When the movable plate 9 and the U-shaped plate 25 are moved, no friction or collision will occur with the water circulation pipe 16, and different parts are protected. The contact area between the movable plate 9 and the water circulation pipe 16 can be increased by the arc groove 24, and the thickness of the movable plate 9 can be reduced, which plays a role in heat dissipation and cooling, thereby ensuring the normal operation of the distribution cabinet and its internal equipment.

The cooling fan 13 uses the temperature difference between the hot air in the cabinet and the external cold air to perform heat exchange to achieve heat dissipation in the cabinet. The circular holes 21 transmit the cold air generated by the cooling fan 13 to the equipment housing 1 through multiple groups of circular holes 21, so that the heat of multiple groups of distribution units is reduced. The sensor 12 and the controller 20 are connected to the two groups of cooling fans 13 through cables. The sensor 12 monitors the temperature inside the cabinet, converts the temperature data into electrical signals and outputs them to the controller 20. The controller processes and calculates according to the data provided by the sensor, and outputs control signals to the cooling fans 13, so that the two groups of cooling fans 13 are started.

[0030] According to the attached Figure 8As shown, a movable frame 10 is fixed to the inner wall of the movable plate 9 by screws, and the movable frame 10 is provided with multiple groups, and the sizes of the multiple groups of movable frames 10 are different.

During maintenance, the designated movable frame 10 and the distribution unit can be taken out separately by screws, which is convenient for maintenance and repair; the movable plate 9 has low density, light weight and corrosion resistance, while maintaining high strength and toughness, and can transfer the heat generated by different distribution units to the water circulation pipe 16, and absorb and take away the heat inside the distribution cabinet through the circulating water, so as to achieve the purpose of heat dissipation and improve the heat dissipation performance of the equipment.

[0031] According to the attached Figure 8 As shown, a heat dissipation hole 23 is provided at the bottom end of the inner wall of the movable plate 9, a reserved hole 22 is provided at one end of the movable plate 9, and reserved holes 22 are respectively provided at one end of the movable plate 9 and one side of multiple groups of movable frames 10, and multiple groups of reserved holes 22 are provided at equal distances.

The bottom end of the movable frame 10 is set to be hollow. The reserved holes 22 facilitate wiring between different distribution units, reduce the difficulty of connection and installation, and the heat dissipation holes 23 provide channels for the circulation of heat.

[0032] According to the attached Fig. 9 As shown, a U-shaped plate 25 is fixed to the back of the movable plate 9, an electric push rod 27 is installed on the inner wall of the equipment housing 1, and a connecting plate 28 is fixed to the piston end of the electric push rod 27, connecting rods 29 are hinged at both ends of the connecting plate 28, and a movable plate 30 is hinged at the other end of the connecting rod 29, and multiple groups of U-shaped plates 25 are provided, and the multiple groups of U-shaped plates 25 are symmetrically arranged on the back of the movable plate 9. The movable plate 30 is movably inserted in the U-shaped plate 25.

[0033] According to the attached Fig.11 As shown, a square slider 31 is fixed to the back of the movable plate 30, and square slide grooves 26 are symmetrically provided at both ends of one side of the rear door plate 7, and the square slide grooves 26 are adapted to the square slider 31, and the two are slidably inserted. As the movable plate 30 moves, the square slider 31 slides left and right in the square slide groove 26, and the moving positions of the square slider 31 and the movable plate 30 are limited, so that the movable plate 30 and the square slider 31 can only move left and right.

[0034] The sensor 12, cooling fan 13, water pump 18, pressure water level detector 19, controller 20 and electric push rod 27 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be repeated here.

[0035] Working principle: put the whole device in a suitable position, move the device through the universal wheel 2, open the front door panel 3 and the rear door panel 7 for maintenance, and start the water pump 18 and the electric push rod 27 in the device through external remote control; During maintenance, the electric push rod 27 is started, so that the piston end of the electric push rod 27 drives the connecting plate 28 upward to move, so that the use angle of the two sets of connecting rods 29 is rotated and moved, and the two sets of connecting rods 29 become vertical, driving the two sets of movable plates 30 and the square slider 31 to move toward the middle at the same time, so that the square slider 31 slides in the square slide groove 26, so that the movable plate 30 is moved out of the U-shaped plate 25, and then the handrail on the surface of the movable plate 9 is held, and the movable plate 9 and the U-shaped plate 25 are pulled out of the square slot 17, so that the multiple sets of The moving frame 10 is pulled out, and the arc groove 24 is away from the water circulation pipe 16. As the moving plate 9 moves, the slider 14 and the L-shaped plate 15 slide in the fixed block 8. Finally, different moving frames 10 and distribution units can be taken out in turn by screws. After maintenance, the moving frame 10 and the distribution unit are installed and restored, and the moving plate 9 is pushed into the deep of the equipment housing 1, so that the arc groove 24 on the back of the moving plate 09 contacts the water circulation pipe 16. Similarly, the electric push rod 27 is started in the reverse direction, so that the U-shaped plate 25 is limited by the controller 20. When in use, water is injected into the water tank 5 by removing the sealing plug, and the pressure water level detector 19 detects the water level. After the lowest water level is prompted, the water adding operation is performed. The water pump 18 transfers the water in the water tank 5 to the water circulation pipe 16. The water in the water circulation pipe 16 circulates, and the heat of the equipment housing 1 and the distribution unit is reduced through the movable plate 9. At the same time, the sensor 12 and the controller 20 start two sets of cooling fans 13. The cooling fan 13 introduces external cold air into the equipment housing 1 through the dustproof net 4, and exchanges heat with the hot air in the cabinet. Then the cooling fan 13 simultaneously flows the cold air through the circular hole 21 to the bottom of the partition 11, and flows out along the cooling holes 23 at the bottom of the movable plate 9 and the movable frame 10. Finally, the heat flows out along the dustproof net 4 on the surface of the front door panel 3 through the gap between the slider 14 and the equipment housing 1. The heat inside the equipment housing 1 is evenly and dispersed through the rising of hot air and the sinking of cold air to perform heat dissipation treatment.
