The person who was called a fool in the doggerel was the director of another 100-ton repair factory, but he was simply implicated by Sun Shanming and Lin Zhenkang. As soon as the joke came out, he also came under public scrutiny, and some people
He took the opportunity to vent his dissatisfaction with him, and was eventually slandered as a fool.
Li Qinjun, a native of Liaoning, went abroad during the Beiyang years and graduated with a master's degree in science and engineering. After returning to China, he entered a shipyard in the Northeast and became an apprentice at the shipyard. He systematically studied ship-related design and construction, and participated in or presided over many projects.
Ship construction.
Before September 18th, he had been out of the army and was responsible for all the work of a small shipyard for several years. After September 18th, the shipyard was taken away by Japanese businessmen, and he quietly withdrew southward with his family.
Finally, he came to Shanghai and re-employed a shipyard, but his resume was not outstanding. Most of the ships he participated in the construction were small boats that could only sail in the Bohai Sea, and most of the ships built by the shipyard he was responsible for ran on inland rivers.
Motorized boats are mainly iron-hulled boats and iron-framed wooden-hulled boats, and there is even a lot of work to modify the sails.
Therefore, his position in the Shanghai shipyard was not high and he only did some auxiliary work, so when the Lin family approached him, he readily agreed.
His resume is not top-notch among the people recruited by the Lin family, but the small shipyard he was responsible for was very similar to the Lin family's 100-ton shipyard, and the ships he built were very similar. In addition, the shipyard was only
He was the lowest grade in the Lin family shipyard, so he was appointed as the factory director after consideration.
It can be said that his performance is completely in line with most of the Lin family's imaginations of a shipyard director. He understands technology and can handle various technical problems even if he cannot solve them himself.
The problem is clearly understood and what kind of help is needed, and it can be reported accurately, clearly and meticulously. As long as the Lin family follows the instructions, they will basically avoid any misunderstandings.
All affairs in the shipyard are handled in an orderly manner, and all matters are advanced in an orderly manner. He has a very thorough understanding of the needs of the Lin family and can propose various effective solutions, solutions, etc., to meet the needs of the Lin family.
The source of the ridicule and mudslinging was a new ship designed and built by its organizers. It suffered a serious malfunction during the test and eventually sank. Judging from the results alone, it was by far the most successful among the three shipyards.
serious accident.
But the accident had nothing to do with it. When the Lin family purchased the ship's power system components, the seller mixed some defective products into them. They were not even considered defective products, but scrap products that the factory should not be able to produce.
When he was testing the ship, the engine drive shaft suddenly broke. Because it was running at full power at the time, the broken shaft and debris were extremely powerful, damaging the engine and penetrating the oil pipeline, causing the ship to lose its main power and causing a fire in the engine room.
.
Because it was a small boat, the main engine and the auxiliary power engine were both in the same engine room. Once the fire started, the temperature rose rapidly, and the two auxiliary power engines stopped one after another due to the temperature.
Fortunately, the captain who was testing the ship was very experienced, and Li Qinjun had given careful instructions beforehand. As soon as the ship had a problem, he immediately sailed to the shore. When the ship lost all power and was not far from the shore, the captain immediately made the decision to abandon the ship and swim ashore. Otherwise, he would have probably lost his life.
There were casualties.
The water flow in the test section of the river was very fast. Even if it was not far from the shore, it would be dangerous for the crew to get ashore. The boat was carried away by the current, hit several rocks and sank directly. After being salvaged later, it was found that the river water was still flowing far away, and people were killed.
It's unimaginable to be swept away.
The Lin family organized many people to study the cause of the ship's problem. The final conclusion was that there was a serious problem with the transmission shaft, and during the blank processing stage, due to improper operation, serious hidden damage was formed on the steel, causing the processed transmission to be damaged.
The shaft has a huge defect problem.
This defect is obvious and can be easily discovered during processing, inspection and other aspects. The items should be scrapped directly, but for some reason, they still continue to be processed, and finally let the dealer mix it with the good ones and sell them to the Lin family.
Through the inspection of other goods purchased from the same dealer, some problematic products were discovered. The other party obviously did it deliberately, so the problem appeared on the dealer and the Lin family who did not know much about the industry.
As for the shipyard, on the one hand, the Lin family purchased the items; on the other hand, others had also covered up the problem areas, so the problems were discovered very quickly, and the shipyard did not have a corresponding inspection department.
During this period, few domestic factories had a complete set of processes, which was normal. However, the shipyard had learned its lesson and organized dedicated personnel to carefully inspect the purchased materials and parts before using them.
When it came to building a new ship, Li Qinjun was not like Sun Shanming who was overjoyed about his success, nor was he like Lin Zhenkang, who was itchy and reluctant to get started when he saw the success of others. Instead, he really believed that the Lin family needed such a ship, so he organized people to conduct research.
Design and build.
Li Qinjun presided over the design and construction of a small boat of 20 to 30 tons, which was used to tow or push other ships, that is, a small tugboat.
The reason is that it was learned that the Lin family modified their ships mainly to allow normal navigation on the Yangtze River waterway entering and exiting Sichuan and Chongqing. After research, they believed that even in the Three Gorges section, only a small section of the river has very turbulent water flow. There is no need for normal navigation.
Through this small section of the river, a more powerful power system is installed on the ship.
The purpose of developing tugboats is to help ships navigate this part of the river through tugboat dragging, pushing, etc., so that the carrier ships can choose to be equipped with lower power power systems, so they can navigate inside and outside Sichuan and Chongqing, thereby reducing
Modification costs.
After all, waterways with extreme conditions only account for a very small part of the entire journey, and for this small part, it is definitely very uneconomical to significantly increase the installed power.
Normal commercial shipping pays attention to cost-effectiveness, that is, the unit price or cost of transporting people and goods should be as low as possible. Even if a high-power engine is installed, during normal navigation, a trade-off must be made between speed and consumption.
In water transportation, speed and fuel consumption do not increase in equal proportions. Even if the installed power is very sufficient, for the sake of economy, there is a high probability that it will not be used in normal navigation. The large amount of excess power will be used most of the time.
If you don’t use it, wouldn’t it be a waste?
The Lin family lacks transportation capacity, but the transportation of raw materials, equipment, etc. often takes thousands of kilometers, and the products produced may have to be transported out of Sichuan. Therefore, the Lin family still needs to consider economics for most of the transportation. This ship type is also very
It meets the needs of the Lin family.
Moreover, transportation capacity and reducing shipping power are not completely in conflict and opposition. Even if the Lin family is not short of money and can purchase many high-horsepower engines, the difficulty of obtaining high-horsepower and low-horsepower engines is different.
Even the difficulty and time of installing the two onto the ship are different. Installing a lower-horsepower engine on the transport ship will obviously provide more modified ships faster. In a detailed calculation, it can still
Provide more transportation capacity faster.
The tugboat is equipped with a high-horsepower engine as the main power and two lower-horsepower engines as auxiliary power and backup engines when necessary. Like Lin Zhenkang's boat, it uses three engines and three propellers.
Most of the reasons why small boats use multiple oars are to prevent accidents. Unfortunately, things happened in unexpected places. However, after investigation, the Lin family still recognized and accepted this boat. At present, many of them have been built and put into use.
.
The reason for being scolded is that one is being implicated and dragged down, and the other is that some people are targeting, slandering, and throwing dirty water. Who is he? In fact, you can hear this from the wording in the doggerel, idiot, idiot, etc.
Class is basically a word used in Sichuan and Chongqing.
There are a large number of Sichuan and Chongqing poor people working in the Three Gorges waterway to make a living. Li Qinjun built this boat, and Minxian was considered to be a threat to their jobs. Of course, it is definitely not them who are slandering and throwing dirty water, but those who call themselves
It's the guy who speaks for them.
Those who say this are either stupid or bad. What the Lin family is doing is incremental, and this move can greatly increase the navigation volume of the Three Gorges. One liter of shipping volume, the associated loading and unloading, freight transportation and even the built factories can bring a large number of employees.
Demand, and the demand for catering and other services, can also provide more opportunities to make a living. At least many people no longer have to work hard to squeeze here to get fiber optics, instead of being unable to find other ways out like now.
Let’s get back to the topic, the tug-barge fleet we met on Lin Mo Road. On both sides of the fleet, the smaller boats that don’t burn coal are tug boats designed and built by Li Qinjun.
The one that towed the fleet at the beginning was an extension of the original tugboat, so the two looked a little weird. After the main engine of this ship was replaced by a coal-burning high-horsepower steam engine, the fuel was replaced by coal, mainly for
Long-distance towing reduces costs. The ship is being refitted on an expedited basis. After a certain amount of experience is accumulated, a new ship type will be designed that is more suitable for this job.
As for the barges, they were the ones designed and built by Sun Shanming. Li Qinjun was also responsible for cleaning up the mess. He was mainly the director of the three factories. He was the only one who was reliable. As for the other talented people with more famous titles, after Sun Shanming's incident, the Lin family also had some
I was scared, but I also sent them to the team to deal with the aftermath, to try out their skills first, so as not to make a joke again when I join the company later.
After some discussion, these people finally agreed that the only way to change the formed ship into a barge was to move the control room, engine room, etc. on the bow side to the stern side, and cut off the bow section.
The ship has been shortened, and its performance has been optimized and improved in all aspects, making it more suitable for domestic waterway needs. At the same time, it has been replaced with a rudder-wing system that can greatly increase stability and anti-wave performance. After some modifications, the ship can basically
It can travel normally in most inland waters in the country.
The engine room was moved to the stern, and only one low-horsepower engine was retained. It used parking brakes, small maneuvers in and out of the dock, slow and short-distance maneuvers in calm waters, etc. The main purpose of removing the high-horsepower engine was to reduce weight and adjust the center of gravity of the ship.
Line these.
The only engine was retained by Li Qinjun after repeated insistence. The consideration point is exactly the same as the design and construction of the tugboat. Keeping a small number of moving boats can allow the barge to have wider applicability, such as braking to stop the ship, entering and exiting the dock, etc.
If this kind of work requires the assistance of other ships, it will be very troublesome and inconvenient, which will greatly reduce the practicality of the ship. Just a small investment in adding some auxiliary power to it can greatly improve these problems, which is very cost-effective.
