[0027] like Figures 1 to 5 As shown, a high and low voltage cabinet with a waterproof insulation structure includes: a fixed box 1, an air outlet 102 is provided inside the fixed box 1, and the air outlet 102 is connected to the fixed box 1, a connecting groove is provided inside the fixed box 1, and a rotating plate 101 is provided on the outside of the fixed box 1; a sealing mechanism for blocking water, the sealing mechanism includes a support member 2, a drying member 3 and a sealing member 4, the support member 2 is arranged on the outside of the fixed box 1 for providing support for the fixed box 1, the drying member 3 and the sealing member 4 are arranged inside the support member 2, the sealing member 4 is used to guide the air, the drying member 3 is used to filter moisture in the air, and the drying member 3 cooperates with the sealing member 4 to block water. Specifically, when it is necessary to use the fixed box 1 to install electrical components, the electrical components are first protected by the fixed box 1 in cooperation with the rotating plate 101. While protecting the electrical components, the air entering the fixed box 1 is filtered by the cooperation of the support member 2 and the drying member 3 to prevent dust and moisture from entering the fixed box 1 during use. Inside, ensure the stability of the electrical components during use, and finally block water through the cooperation of the seal 4 and the support 2 to prevent water from invading the fixed box 1 through the support 2 and causing a short circuit in the electrical components. A sealing strip is provided between the rotating plate 101 and the fixed box 1 to prevent water and air from penetrating into the fixed box 1 through the gap between the rotating plate 101 and the fixed box 1 during use. The electrical components include switches, circuit breakers, fuses, buttons, indicator lights, instruments and various protective devices, etc. The electrical components are all existing technologies and will not be explained in detail here. The electrical components and the fixed box 1 can be connected by snaps or bolts, which is convenient for quickly adding and replacing electrical components during use. A fan is provided inside the air outlet 102, and the fan can discharge the air inside the fixed box 1 through the air outlet 102. A control valve is provided inside the air outlet 102 to control the air flowing inside the air outlet 102 to prevent air outside the fixed box 1 from entering the fixed box 1 through the air outlet 102.
[0028] like Figures 1 to 5As shown, the support member 2 includes a support block 201, the support block 201 is open on one side, the open side of the support block 201 is connected to the fixed box 1, and the support block 201 is located directly below the connecting groove, and the support block 201 is connected to the connecting groove, the outer side of the support block 201 is opened with at least one air inlet 202, and the air inlet 202 passes through the support block 201, and the first baffle 203 and the second baffle 204 are sequentially provided at one end of the opposite surface of the air inlet 202, and the first baffle 203 and the second baffle 204 are connected to the support block 201, and the first baffle 202 03 is provided with a guide groove 205 on one side opposite to the support block 201. Specifically, during use, the air entering the air inlet 202 is guided by the cooperation of the first baffle 203 and the second baffle 204 to prevent the air from directly entering the support block 201 during use. The support block 201 and the fixed box 1 are connected by bolts or snaps, and a sealing ring is provided between the support block 201 and the fixed box 1 to prevent the air from entering the support block 201 through the gap between the support block 201 and the fixed box 1 during use.
[0029] like Figures 1 to 5 As shown, the drying member 3 includes a fixing frame 301, which slides inside the support block 201, and the support block 201 is located just below the connecting groove. A drying block 302 is provided inside the fixing frame 301, and an air inlet 303 is provided on the outside of the drying block 302, and the air inlet 303 is connected to the support block 201. Specifically, during use, the drying block 302 can filter dust and moisture in the air to ensure that the air entering the fixed box 1 is dry and clean. There is a movable gap between the drying block 302 and the fixing frame 301. The connection is detachable, so that the drying block 302 can be replaced after being used for a long time, ensuring the air filtering effect. The air entering the support block 201 can be guided into the fixing frame 301 through the air inlet hole 303, so that the drying block 302 filters the air. The fixing frame 301 and the support block 201 are connected by threads or buckles, and the fixing frame 301 can be pulled out from the support block 201, which is convenient for replacing the drying block 302 when the drying block 302 is blocked.
[0030] like Figures 1 to 5As shown, the sealing member 4 includes a plurality of fixing strips 401, which are arranged between the first baffle 203 and the support block 201. A through hole 402 is provided on the outside of the fixing strip 401, and the through hole 402 passes through the fixing strip 401, and the open end of the fixing strip 401 is parallel to the height direction of the fixed box 1. A plurality of connecting rods 405 are provided inside the fixing strip 401, and the connecting rod 405 moves relative to the fixing strip 401, and the moving direction of the connecting rod 405 is parallel to the opening direction of the through hole 402. A sealing block 406 is provided inside the through hole 402, and the sealing block 406 is adapted to the through hole 402, and one end of the sealing block 406 is connected to the connecting rod 405, and the other end of the connecting rod 405 is sleeved with a spring 407. Specifically, when the water level rises, the sealing block 406 slides into the through hole 402 under the push of the water, so that the sealing block 406 cooperates with the through hole 402 to control the air flow channel between the first baffle 203 and the support block 201. Blocking prevents water from entering the fixed box 1 through the air inlet 202, ensuring the stability of the electrical components during use. The fixing strip 401 is placed between the first baffle 203 and the support block 201, so that air can only enter the fixed box 1 through the through hole 402. The adaptation of the sealing block 406 to the through hole 402 means that the sealing block 406 can be inserted into the through hole 402 and the through hole 402 is blocked by the sealing block 406 to prevent water from entering the fixed box 1 through the through hole 402 when the water level rises. A sealing gasket is provided between the sealing block 406 and the through hole 402 to further ensure the water blocking effect. The shape of the sealing block 406 can be cylindrical, hexagonal or elliptical, etc. The connecting rod 405 connects the sealing block 406 and the fixing strip 401. The spring 407 can provide the sealing block 406 with the power to reset when it is used, so that the sealing block 406 can automatically slide out from the through hole 402 after the water level drops.
[0031] like Figures 1 to 5 As shown, a connecting frame 403 is further provided on the outside of the connecting rod 405, and a guide block 404 is provided on the outside of the connecting frame 403, and the guide block 404 slides inside the guide groove 205. Specifically, when in use, multiple connecting rods 405 are connected through the connecting frame 403 to ensure that the multiple connecting rods 405 can move synchronously to avoid the sealing block 406 from tilting relative to the fixed bar 401 during movement. The guide block 404 cooperates with the guide groove 205 to further guide the moving direction of the connecting frame 403, further ensuring the accuracy of the moving direction of the connecting frame 403.
[0032] like Figures 1 to 5As shown, the interior of the sealing block 406 is hollow, and the density of the sealing block 406 is less than that of water. Specifically, when the water level rises, since the density of the sealing block 406 is less than that of water, the sealing block 406 can always float on the water surface during the rising water level. The hollow sealing block 406 further increases the buoyancy of the sealing block 406, ensuring that the sealing block 406 can fit tightly with the through hole 402 when the water level rises. The buoyancy of the sealing block 406 is greater than the elastic force of the spring 407, ensuring that the sealing block 406 can fit tightly with the through hole 402 during the rising water level.
[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention.
