The cleaning plate 28 and the adjustment frame 24 form an integrated sliding structure, and the outer wall of the cleaning plate 28 is slidably connected with a dustproof net 5.

[0032] The specific implementation method is as follows: through the reciprocating screw 22, the adjustment frame 24 and the cleaning plate 28, the reciprocating screw 22 drives the adjustment ring 23 to perform reciprocating adjustment. At this time, the adjustment frame 24 is driven by the adjustment ring 23 to perform synchronous adjustment, so that the adjustment frame 24 drives the heat exhaust fan 27 to perform lateral adjustment to complete the discharge of heat dissipated by the radiator 16.

[0033] Working principle: When using the heat dissipation device for transformer equipment, the transformer 6 is first installed on the inner wall of the cabinet 1. The safety of the transformer 6 installed on the inner wall of the cabinet 1 is ensured by the rainproof plate 2 arranged on the top of the cabinet 1 and the protective door 3 installed on the outer wall of the cabinet 1. When the cabinet 1 needs to be cooled after a long period of work, the two fans 4 are started. Since the fans 4 are installed on both sides of the cabinet 1, the two fans 4 replace the air in the cabinet 1.

[0034] Then, the heat generated by the transformer 6 is conducted through the silicone gasket 8 arranged on the inner wall of the heat conducting plate 7, and the heat conducted by the silicone gasket 8 is dissipated through the radiator 16, thereby ensuring the working stability of the internal parts of the heat conducting plate 7. At the same time, the motor 19 is started, and the motor 19 drives the transmission rod 20 to rotate, so that the reciprocating screw 22 rotates synchronously with the transmission rod 20 through the transmission device 21, so that the reciprocating screw 22 drives the adjustment ring 23 connected to the outer wall thread to reciprocate and slide, and then the adjustment frame 24 is driven by the adjustment ring 23 to be adjusted synchronously;

[0035] At this time, the adjusting frame 24 drives the movable ring 25 to slide along the fixed rod 26, so that the adjusting frame 24 drives the heat exhaust fan 27 to adjust horizontally, and completes the discharge of the heat dissipated by the radiator 16. At the same time, the adjusting frame 24 drives the cleaning plate 28 to adjust synchronously, thereby driving the cleaning plate 28 to slide along the outer wall of the dustproof net 5, thereby completing the treatment of dust on the surface of the dustproof net 5;

[0036] When the staff needs to quickly dissipate heat from the heat conducting plate 7, the cylinder 9 is started to drive the adjusting plate 10 to move up and down. Since the outer wall of the adjusting plate 10 is slidably connected to the first slide rail 12, the stability of the adjusting plate 10 in moving up and down is guaranteed, thereby driving the slide groove 11 provided through one side of the adjusting plate 10 to be synchronously adjusted, and then the slide rod 14 provided on the inner wall of the slide groove 11 slides along the track of the slide groove 11;

[0037] At this time, the slide rod 14 drives the adjustment rod 15 to be adjusted synchronously, so that the adjustment rod 15 is adjusted in spacing along the trajectory of the slide groove 11, thereby driving the slide plate 17 to slide along the second slide rail 18 through the adjustment rod 15, and then driving the five radiators 16 to be adjusted in spacing through the slide plate 17, thereby increasing the contact area between the radiator 16 and the silicone gasket 8, and at the same time accelerating the air circulation speed between adjacent radiators 16, improving the heat dissipation effect of the radiator 16, and thereby achieving rapid heat dissipation of the transformer 6.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
