[0002] A high-pressure submersible pump is a pump that can work underwater and provide high-pressure water flow. It is usually composed of a pump body, a motor and a control device. The pump body is usually made of corrosion-resistant materials to meet the special requirements of the underwater environment. The motor is usually designed to be waterproof to ensure safety and reliability when working underwater. The control device is used to control the operation of the pump and can adjust the water pressure and flow as needed. The control device needs to be protected during use of the host, so a control box is required.

Moreover, some existing control boxes are not equipped with heat dissipation devices. When the electrical components are in use, a large amount of heat will be emitted. The electrical components are in a high temperature environment for a long time, which is prone to aging and reduces the service life. Utility Model Content

A dehumidification mechanism is used to dehumidify the interior of the box 1. A fixing mechanism for fixing electrical components is provided on the inner wall of the box 1. During use, the device can cool and dehumidify the interior of the box 1 through the cooperation of the air supply mechanism and the dehumidification mechanism. The air passing through the dehumidification mechanism is converted into low-temperature dry gas. The low-temperature dry gas enters the box 1, creating a good working environment for the electrical components and extending the service life of the electrical components. The spacing between the electrical components can be changed through the fixing mechanism without disassembly, saving much time and improving work efficiency.

[0022] Reference Figure 2 and Figure 4 In a preferred embodiment, the air supply mechanism includes a fan 15, and the fan 15 is rotatably connected to the top of the circular hole in the box body 1. Air inlet pipes 7 are fixed to the symmetrical two side walls of the connecting seat 14, and the two air inlet pipes 7 are connected to the connecting seat 14. A second air inlet port 17 is opened on the top of the inner wall of the two air inlet pipes 7. When the fan 15 is working, the outside air can be blown into the connecting seat 14 through the first air inlet port 5, and the air entering the connecting seat 14 enters the two air inlet pipes 7 respectively.

[0023] Reference Figure 4 and Figure 5 In a preferred embodiment, a ring seat 18 is fixed to the bottom of the connecting seat 14, and a filter screen 19 is fixed to the inner wall of the ring seat 18. The filter screen 19 can filter the outside air to prevent dust in the air from entering the interior of the box 1 and damaging the electrical components.

[0024] Reference Figure 4 and Figure 5In a preferred embodiment, the dehumidification mechanism includes a first fin 4 and a second fin 13, a semiconductor refrigeration plate 16 is arranged inside the second air inlet 17, a plurality of second fins 13 are obliquely fixed to the cold end of the semiconductor refrigeration plate 16, and a plurality of first fins 4 are fixed to the hot end of the semiconductor refrigeration plate 16. A mounting groove is provided on the side wall of the box body 1, and the plurality of first fins 4 are all in the mounting groove. When the semiconductor refrigeration plate 16 is working, the surface temperature of the second fin 13 is relatively low, and part of the heat in the box body 1 is dissipated to the external environment through the first fin 4. The air passing through the second fin 13 is converted into low-temperature dry gas. The low-temperature dry gas enters the box body 1 through the second air inlet 17, and another part of the heat in the box body 1 is discharged outside the box body 1 through the second air outlet 3, thereby creating a good working environment for the electrical components and extending the service life of the electrical components.

[0025] Reference Figure 2 and Figure 3 In a preferred embodiment, the fixing mechanism includes a U-shaped seat 8 and a mounting bracket 10, U-shaped seats 8 are fixed to both symmetrical ends of the top of the fixing plate 6, and slide grooves 9 are provided on the side walls of the two U-shaped seats 8.

The side wall of the box body 1 is rotatably connected with the box door 2. When the electrical component needs to be repaired, the threaded sleeve 12 is rotated to gradually move the threaded sleeve 12 away from the U-shaped seat 8, so that the limiting effect on the mounting bracket 10 can be released.

There is no need for workers to disassemble it, which saves a lot of time and improves work efficiency.

[0026] Working principle of this embodiment: During the use of this device, since the temperature sensor 20 is connected to the controller, the controller controls the switch of the fan 15 and the semiconductor cooling plate 16. When the temperature inside the box 1 is too high, the temperature sensor 20 generates an electrical signal and transmits it to the controller. After the controller receives the signal, it turns on the switch of the fan 15 and connects the semiconductor cooling plate 16. At this time, the surface temperature of the second fin 13 is relatively low, and part of the heat in the box 1 is dissipated to the external environment through the first fin 4. When the fan 15 switch is turned on, the fan 15 starts to rotate, and the outside air is blown into the connecting seat 14 through the first air inlet 5. The air entering the connecting seat 14 enters the two air inlet pipes 7 respectively. The surface of the second fin 13 at the cold end of each semiconductor refrigeration plate 16, the air passing through the second fin 13, is converted into low-temperature dry gas, the low-temperature dry gas enters the box body 1 through the second air inlet 17, and the high-temperature gas in the box body 1 is discharged out of the box body 1 through the second air outlet 3, so as to create a good working environment for the electrical components and extend the service life of the electrical components. When the electrical components need to be repaired, the threaded sleeve 12 is rotated to gradually move the threaded sleeve 12 away from the U-shaped seat 8, so as to release the limiting effect on the mounting frame 10. At this time, the mounting frame 10 can move up and down along the slide groove 9 to change the gap between the electrical components without the need for workers to disassemble them, thereby saving a lot of time and improving work efficiency.
