[0002] The main effects of humidity on electrical equipment are insulation strength, mold growth, and metal corrosion. High humidity reduces the insulation strength of electrical equipment. Moisture in the air adheres to the surface of the insulating material, reducing the insulation resistance of the electrical equipment. The leakage current of the equipment is greatly increased, causing insulation breakdown, creepage or flashover, and electrical failure. Humid air is conducive to the germination and growth of mold spores. When the hyphae are covered with a mesh on the surface of the insulator, the insulation performance of the product is greatly reduced. During the metabolism process, molds will also secrete acidic substances, causing a dark film on the conductive metal and electrical contact material, resulting in increased contact resistance. If it is in such an environment for a long time, it will corrode the circuit, reduce the accuracy of the instrument, or cause equipment failure, or even burn the instrument.

[0018] The staff rotates the handle 13, which drives the bevel gear transmission structure 301 to rotate. The bevel gear transmission structure 301 drives the nut pair 1 303 to move up and down in the opposite direction through the screw rod 1 302. The two nut pairs 1 303 drive the two limit structures 4 to move up and down, so as to install the dehumidification device housing 1 on the electrical equipment;

[0019] The limiting structure 4 includes a telescopic rod 401 installed on the outer wall of one side of the screw rod 302, a threaded rod 402 is installed at the movable end of the telescopic rod 401, the bottom end of the threaded rod 402 penetrates the outside of the movable end of the telescopic rod 401 and is fixed with a pressure plate 403, and a latch 404 is installed at one end of the surface of the telescopic rod 401;

[0020] After the staff adjusts the distance adjustment structure 3, the two telescopic rods 401 clamp the electrical equipment, adjust the length of the two telescopic rods 401 by the latch 404, and then rotate the two threaded rods 402 so that the pressure plate 403 at the bottom of the threaded rods 402 presses the electrical equipment, thereby installing the dehumidifier housing 1 on the outer wall of the electrical equipment;

[0021] An exhaust fan 5 is installed on the inner wall of one side of the dehumidification device housing 1, a heater 6 is installed inside the dehumidification device housing 1 on one side of the exhaust fan 5, and a moisture filtering structure 7 is installed on the side of the heater 6 away from the exhaust fan 5.

A gear column 903 is rotatably installed on the top of the dehumidifier housing 1, and the gear column 903 and the rack 902 are meshed with each other.

[0023] The reduction motor 8 drives the double-link structure 901 to rotate. When the double-link structure 901 rotates, since the upper and lower links are hinged to each other, the upper link at the top of the double-link structure 901 rotates with the reduction motor 8, and the upper link drives the lower link to move left and right along the X-axis, thereby driving the rack 902 to move left and right along the X-axis. The left and right movement of the rack 902 drives the gear column 903 to rotate, thereby realizing the reciprocating rotation of the gear column 903;

[0024] A drain pipe 12 is installed on the outer wall of one side of the dehumidifier housing 1, and a condensing mechanism 11 is installed inside the dehumidifier housing 1 on the side of the drain pipe 12.

[0025] The reciprocating rotation of the gear column 903 drives the bidirectional screw 1001 to rotate forward and reversely, and the rotation of the bidirectional screw 1001 drives the nut pair 1002 at both ends of the surface of the bidirectional screw 1001 to move oppositely or relatively, thereby driving the fans 1003 on one side of the surface of the two nut pair 1002 to move relatively or oppositely, thereby achieving the purpose of cooling the liquid inside the condensation mechanism 11;

[0026] A drain pipe 12 is installed on the outer wall of one side of the dehumidifier housing 1, and a condensing mechanism 11 is installed inside the dehumidifier housing 1 on one side of the drain pipe 12. The condensing mechanism 11 includes a return pipe 1101 installed at one end inside the dehumidifier housing 1, and a condensing box 1102 is installed on the side of the return pipe 1101 away from the moisture filtering structure 7. The return pipe 1101 and the condensing box 1102 are connected to each other. A water pump 1103 is installed on the outer wall of one side of the condensing box 1102, and the discharge end of the water pump 1103 is connected to the liquid inlet end of the return pipe 1101, and the input end of the water pump 1103 is electrically connected to the output end of the control panel 14;

[0027] The water pump 1103 continuously extracts the condensate in the condensation box 1102 to the return pipe 1101 for reflux, and the fan 1003 cools the condensate in the return pipe 1101 by blowing air. The residual gas heated by the heater 6 is condensed into small water droplets when it contacts the cooling liquid in the return pipe 1101 and flows out along the drain pipe 12. The second layer of drying is set to accelerate the drying rate of the electrical equipment;

[0028] The output end of the control panel 14 is electrically connected to the input ends of the exhaust fan 5 , the heater 6 , the reciprocating drive unit 9 , and the condensing mechanism 11 .

[0029] When the embodiment of the present application is in use, the staff first adjusts the front shell 2 by turning the handle 13 to adjust the distance between the two limiting structures 4 so that the limiting structure 4 can be fixed on the heat dissipation port of the electrical equipment, and then turns on the exhaust fan 5, the heater 6, the reduction motor 8, the reciprocating drive unit 9 and the condensing mechanism 11 through the control panel 14 to work. The exhaust fan 5 draws the humid gas in the electrical equipment into the interior of the dehumidification device housing 1, and then the heater 6 heats the humid air entering the interior of the dehumidification device housing 1, and the humid air is filtered and dried by the moisture filtering structure 7. Because the reciprocating drive unit 9 drives the sweeping blower mechanism 10 to move up and down continuously, the sweeping blower mechanism 10 continuously blows air to cool the refluxed liquid in the condensing mechanism 11, and the residual water vapor in the air filtered by the moisture filtering structure 7 is cooled into water again by the condensing mechanism 11, and finally the water and The dry air flows out along the drain pipe 12. The arrangement of the distance adjustment structure 3 and the limit structure 4 enables the dehumidifier housing 1 to be fixed on electrical equipment of different sizes, thereby improving the use range of the dehumidifier housing 1. The dehumidifier housing 1 has strong flexibility and is easy to use. The reciprocating drive unit 9 drives the sweeping blower mechanism 10 to continuously blow air up and down on the condensing mechanism 11, thereby accelerating the cooling speed of the liquid in the condensing mechanism 11 and improving the cooling effect of the condensing mechanism 11 on the humid gas. The double drying of the gas by the moisture filtering structure 7 and the condensing mechanism 11 improves the drying effect of the dehumidifier on the electrical equipment and accelerates the drying rate of the electrical equipment. The dehumidifier housing 1 is arranged outside the electrical equipment for use to extract the humid gas in the electrical equipment, thereby preventing the condensed water droplets from entering the electrical equipment components during the use of the dehumidifier in the electrical equipment and damaging the electrical components, thereby protecting the use function of the electrical equipment components.
