DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 The utility model provides a technical solution: an electrical box with excellent moisture-proof performance, comprising an electrical box 1, shutters 2 are arranged on both sides of the electrical box 1, a drying mechanism 3 is arranged on one side of the electrical box 1, and a heat dissipation mechanism 4 is arranged on one side of the electrical box 1;

[0023] The drying mechanism 3 includes a first vent 301, an air duct 302, a first fixing rod 303, a first fan 304, a first connecting pipe 305, a filter 306, a second connecting pipe 307, a heating wire 308, a protective net 309 and a fixed base 310. The first vent 301 is opened on one side of the electrical box 1, the air duct 302 is fixedly connected to the surface of the first vent 301, the first fixing rod 303 is fixedly connected to the inner surface of the air duct 302, one end of the first fixing rod 303 is fixedly connected to the first fan 304, the inner side of the air duct 302 is fixedly connected to the first connecting pipe 305, the inner surface of the first connecting pipe 305 is fixedly connected to the filter 306, and the inner side of the air duct 302 is fixedly connected to the second The connecting tube 307 and the inner surface of the second connecting tube 307 are fixedly connected with the heating wire 308, the inner side of the air duct 302 is fixedly connected with the protective net 309, and the surface side of the air duct 302 is fixedly connected with the fixed base 310. During use, when it is necessary to input dry air into the interior of the electrical box 1, the first fan 304 can be turned on, and the switch of the heating wire 308 can be turned on at the same time. The first fan 304 will introduce external air through the filter 306. The filter 306 will absorb some moisture due to the nature of its own material. Then the air will be blown to the heating wire 308 by the first fan 304 for heating. At this time, the moisture in the air will be dissipated after being heated, thereby achieving the effect of inputting dry air into the electrical box 1.

[0024] Furthermore, the material of the filter 306 is sponge, and the material of the heating wire 308 is nickel-chromium alloy. Through the setting of the sponge filter 306, a part of the moisture in the air can be filtered out when passing through the sponge filter 306, thereby improving efficiency. Through the setting of the nickel-chromium alloy heating wire 308, the nickel-chromium alloy has a higher resistivity and good heat resistance, and the nickel-chromium alloy material has a small resistance temperature coefficient and a long service life, thereby reducing costs.

[0025] Furthermore, the heat dissipation mechanism 4 includes a second vent 401, a second fixing rod 402, a second fan 403, a first connecting block 404, a temperature sensor 405, a fixing block 406, a driving motor 407, a threaded rod 408, a first limiting block 409, a first limiting groove 410, a transmission block 411, a threaded hole 412, a second connecting block 413, a window door 414, a second limiting block 415 and a second limiting groove 416. A second vent 401 is provided on one side of the electrical box 1, one end of the inner surface of the electrical box 1 is fixedly connected to the second fixing rod 402, the other end of the second fixing rod 402 is fixedly connected to the second fan 403, and the inner surface of the electrical box 1 A first connecting block 404 is fixedly connected to one side of the electrical box 1, and a temperature sensor 405 is fixedly connected to the other end of the first connecting block 404. A fixing block 406 is fixedly connected to one side of the inner surface of the electrical box 1, and a driving motor 407 is fixedly connected to one end of the fixing block 406. A threaded rod 408 is fixedly connected to the output end of the driving motor 407. A first limiting block 409 is fixedly connected to one side of the inner surface of the electrical box 1, and a first limiting groove 410 is provided inside the first limiting block 409. A transmission block 411 is slidably connected to the surface of the first limiting groove 410, and a threaded hole 412 is provided inside the transmission block 411. One end of the transmission block 411 is fixedly connected to the second connecting block 413, the other end of the second connecting block 413 is fixedly connected to the window door 414, and one side of the inner surface of the electrical box 1 is fixedly connected to the second limiting block 415, and one side of the second limiting block 415 is provided with a second limiting groove 416. During use, when the temperature sensor 405 senses that the temperature in the electrical box 1 is too high, the temperature sensor 405 will trigger the switch of the second fan 403, and the temperature sensor 405 will also trigger the switch of the drive motor 407. At this time, the output end of the drive motor 407 drives the threaded rod 408 to rotate, and the rotation of the threaded rod 408 drives the transmission block 411 to move in the first limiting groove 410, and the position of the transmission block 411 The displacement of the second connecting block 413 will drive the window door 414 to move in the second limiting groove 416, so as to achieve the effect of opening the second vent 401 to allow the second fan 403 to ventilate and cool down. The temperature of the electrical box 1 can be controlled. When the temperature sensor 405 senses that the temperature in the electrical box 1 has reached a reasonable level, the temperature sensor 405 will trigger the switch of the second fan 403, and the second fan 403 will stop operating. At the same time, the temperature sensor 405 will also trigger the switch of the drive motor 407, and the window door 414 will reach a certain position to close the second vent 401, thereby reducing energy loss and reducing costs.

[0026] Furthermore, the transmission block 411 is threadedly connected to the threaded rod 408, and the threaded rod 408 is movably socketed with the first limiting groove 410. Through the setting of the transmission block 411 and the threaded rod 408, the rotational motion of the drive motor 407 can be converted into the linear displacement motion of the transmission block 411. Through the setting of the threaded rod 408 and the first limiting groove 410 being movably socketed, it can be ensured that the threaded rod 408 will not be affected during the rotation process.

[0027] Furthermore, there are two groups of second limit blocks 415, which are respectively distributed on both sides of the window door 414. The window door 414 is slidably connected to the second limit groove 416. Through the setting of the two groups of second limit blocks 415, the movement of the window door 414 can be smoother. Through the setting of the window door 414 and the second limit groove 416, the window door 414 can achieve the effect of opening and closing the second vent 401.

[0028] Furthermore, there are two groups of temperature sensors 405 and two groups of second fixing rods 402. By setting two groups of temperature sensors 405, the temperature sensors 405 can detect the temperature in the electrical box 1 more timely and accurately. By setting two groups of second fixing rods 402, the second fan 403 can be fixed more firmly in the electrical box 1.

[0029] Furthermore, the window door 414 and the second vent 401 are movably abutted against each other. By disposing the window door 414 and the second vent, the movement of the window door 414 can be kept unaffected.

[0030] Working principle: During use, when it is necessary to input dry air into the electrical box 1, the first fan 304 can be turned on, and the switch of the heating wire 308 can be turned on at the same time. The first fan 304 will introduce external air through the filter 306. The filter 306 will absorb some moisture due to the nature of its own material. Then the air will be blown to the heating wire 308 by the first fan 304 for heating. At this time, the moisture in the air will be dissipated after being heated, thereby achieving the effect of inputting dry air into the electrical box 1. When the temperature sensor 405 senses that the temperature in the electrical box 1 is too high, the temperature sensor 405 will trigger the first fan 304 to blow the external air through the filter 306. The second fan 403 is turned on and off, and the temperature sensor 405 also triggers the switch of the drive motor 407, so as to achieve the effect of opening the second vent 401 to allow the second fan 403 to ventilate and cool down. The temperature of the electrical box 1 can be controlled. When the temperature sensor 405 senses that the temperature in the electrical box 1 has reached a reasonable level, the temperature sensor 405 will trigger the switch of the second fan 403, and the second fan 403 will stop operating. At the same time, the temperature sensor 405 will also trigger the switch of the drive motor 407, and the window door 414 will reach a certain position to close the second vent 401, thereby reducing energy loss and reducing costs.
