[0002] Marine heat exchangers are essential specialized products in shipbuilding and are crucial for the proper operation of core ship components, such as power systems. Heat exchangers are devices used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. They are an industrial application of convective heat transfer and heat conduction. Frequency converters are primarily used to adjust the operating frequency of equipment, reduce energy loss, and enable smooth equipment startup, minimizing damage to motors caused by the high current generated during direct startup.

[0021] A sealing sleeve 27 is fixedly provided on one side of the square tube 22, and the movable block 24 moves through the sealing sleeve 27 to prevent leakage of hydraulic oil. A first limiting groove 29 is provided on the inner surface of the fixed frame 21, and a first limiting block 291 is slidably provided in the first limiting groove 29. The first limiting block 291 is fixedly connected to the protective plate 25 to prevent the protective plate 25 from detaching from the fixed frame 21. The square tube 22 is provided with a plurality of square tubes, and the square tubes 22 are arrayed on the inner surface of the fixed frame 21 to enhance the buffering force. When an external object contacts the main body 1 of the converter frequency conversion control device, it first contacts the sponge protective pad 26 on one side of the protective plate 25. The protective plate 25 is subjected to force to move the movable block 24, and the square slide 23 slides along the inner wall of the square tube 22. The hydraulic oil inside it flows along the square hole 231, and the buffer spring 28 is compressed under force, thereby forming damping and buffering to prevent the impact force from being transmitted to the interior of the converter frequency conversion control device main body 1 and causing damage to internal components.

[0022] The moisture-proof component 3 includes a connecting frame 31 and a moisture-proof plate 33. The connecting frame 31 is fixedly connected to the lower surface of the converter frequency conversion control device body 1.

[0024] Working Principle: When the present invention is in use, before an external object contacts the main body 1 of the converter frequency conversion control device, it first contacts the sponge protective pad 26 on one side of the protective plate 25. The protective plate 25 is subjected to force to move the movable block 24, and the square slide 23 slides along the inner wall of the square tube 22. The hydraulic oil inside it flows along the square hole 231, and the buffer spring 28 is compressed by force, thereby forming a damping and buffering effect, preventing the impact force from being transmitted to the interior of the converter frequency conversion control device main body 1 and causing damage to the internal components.

[0025] The moisture-proof plate 33 can prevent moisture from entering the interior of the switch frequency conversion control device body 1. After the moisture-proof plate 33 has been used for a period of time, the pull block 38 can be moved to move the stopper 36 downward, and the stopper 36 is out of contact with the moisture-proof plate 33. The old moisture-proof plate 33 can be removed by the protruding rod on one side and the new moisture-proof plate 33 can be pushed in. After releasing the pull block 38, the force of the first spring 35 can be used to move the stopper 36 upward to limit the moisture-proof plate 33.
