[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 4 In the utility model: a dust and sand proof wind power switch cabinet, comprising a cabinet 1, through holes 2 are provided on the left and right sides of the cabinet 1, fans 3 are installed on the inner walls of the two through holes 2, air intake cylinders 4 are fixedly connected to the left and right sides of the cabinet 1, two filter plates 5 are embedded on the outer sides of the two air intake cylinders 4, two slide grooves 6 are provided on the two air intake cylinders 4, sliders 7 are slidably connected to the inner walls of the four slide grooves 6, rings 8 are sleeved on the two air intake cylinders 4, the inner sides of the two rings 8 are fixedly connected to the four sliders 7 respectively, and one side of the four sliders 7 is fixedly connected to a spring 9, and the four springs The other ends of 9 are fixedly connected to the four slide grooves 6 respectively, the inner sides of the two circular rings 8 are fixedly connected to two cleaning brushes 801, the outer sides of the four cleaning brushes 801 are in contact with the two air inlet cylinders 4 respectively, the opposite sides of the two air inlet cylinders 4 are sleeved with rotating cylinders 10 rotatably connected thereto, the inner walls of the two air inlet cylinders 4 are embedded with motors 11, the output shafts of the two motors 11 respectively penetrate the two air inlet cylinders 4 and are fixedly connected to the two rotating cylinders 10 respectively, one side of the two rotating cylinders 10 is fixedly connected to two trapezoidal blocks 12, and the opposite sides of the two circular rings 8 are fixedly connected to sliding rods 13.

[0027] In the utility model, when in use, the two fans 3 are turned on at the same time, the fan 3 on the left side draws external air into the cabinet 1 through the through hole 2, and the air will dissipate heat for the electrical equipment in the cabinet 1, and then the fan 3 on the right side will extract the high-temperature gas in the cabinet 1, thereby effectively improving the heat dissipation effect for the electrical equipment, and in the whole process, the filter plate 5 can effectively prevent sand from entering the interior of the cabinet 1, thereby protecting the switch electrical equipment in the cabinet 1.

[0028] After being used for a period of time, a large amount of sand and dust adheres to the surface of the left filter plate 5. At this time, the user turns on the two fans 3 in reverse at the same time. At this time, the fan 3 on the right is used to input air into the cabinet 1, and the fan 3 on the left will draw air out of the cabinet 1. The air will then pass through the filter plate 5 on the air inlet cylinder 4 in the opposite direction. The air recoil effect will clean the filter plate 5, thereby achieving the self-cleaning effect of the filter plate 5. By repeatedly switching the forward and reverse rotation of the fan 3, the filter plates 5 on the two air inlet cylinders 4 can be cleaned.

[0029] During the cleaning process of the filter plate 5, the user turns on the motor 11 on the air intake cylinder 4 where the filter plate 5 is located. The motor 11 will drive the rotating cylinder 10 to rotate. After the rotating cylinder 10 rotates, it will drive the trapezoidal block 12 to continuously slide over one end of the slide rod 13. When the slide rod 13 slides over the top of the trapezoidal block 12, the slide rod 13 will drive the ring 8 to move. After the ring 8 moves, it will drive the slider 7 to slide along the inner wall of the slide groove 6 and compress the spring 9 until the slide rod 13 completely slides over the trapezoidal block 12. At this time, the elastic force of the spring 9 will be released, and the ring 8 will be quickly driven to reset by the elastic force of the spring 9. As the rotating cylinder 10 rotates, the ring 8 will reciprocate left and right. During the process, the cleaning brush 801 will continuously slide on the filter plate 5, thereby scraping off the stubborn sand and dust attached to the surface of the filter plate 5, thereby improving the cleaning effect of the filter plate 5.

[0030] See also Figure 3 and 4 , wherein: one end of the slide rod 13 is rotatably connected to a roller 14 , and the outer side of the roller 14 is in contact with the rotating cylinder 10 .

[0031] In the utility model, the setting of the roller 14 can reduce friction, improve the running smoothness of the device, reduce wear and tear, and increase the service life of the device.

[0032] See also Figure 2 and 3 , wherein: two square covers 15 are fixedly connected to the inner wall of the cabinet 1, and the bottoms of the two square covers 15 are connected to equidistantly arranged air outlet pipes 16, and the air outlet pipes 16 are provided with equidistantly arranged air outlet holes 17.

[0033] In the utility model, the square cover 15 can collect the air entering the cabinet 1, and distribute it to multiple air outlet pipes 16 to spray it from multiple air outlet holes 17 to the switch devices in the cabinet 1, thereby evenly dissipating the heat of the switch devices and improving the heat dissipation effect of the device.

[0034] See also Figure 2 , wherein: a controller 18 is installed on the inner wall of the cabinet 1, and the output end of the controller 18 is respectively connected to the fan 3 and the motor 11 for signal.

[0035] In the present invention, the controller 18 can facilitate the user to operate and control the fan 3 and the motor 11 to start and stop, thereby improving the practicality of the device.

[0036] See also Figure 3 , wherein: a flow sensor 19 is installed on the inner wall of the left through hole 2, and the output end of the flow sensor 19 is connected to the controller 18 signal.

[0037] In the utility model, the flow rate of air entering and exiting the through hole 2 can be detected by setting the flow sensor 19. The power of the fan 3 remains unchanged. By changing the air flow rate, it can be determined whether the filter plate 5 needs to be cleaned, which is beneficial for cleaning the filter plate 5 as soon as possible and improving the practicality of the device.

[0038] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
