Dust covers 7 are fixedly connected to the outer walls on both sides of the protection box 1. The dust cover 7 is used to prevent dust and other debris from entering the protection box 1 to protect the internal electrical equipment from pollution. A cleaning component is arranged on the outside of the dust cover 7. The function of the cleaning component is to regularly remove dust and dirt attached to the surface of the dust cover 7 to ensure that the dust cover 7 always maintains a good working condition and further improves the protection effect. A mounting block 13 is fixedly connected inside the dust cover 7 to provide a support for subsequent components. A stable installation foundation is formed. The side of the mounting block 13 away from the fan 3 is rotatably connected to the second circular gear 14. The meshing relationship between the second circular gear 14 and the first circular gear 5 forms an effective power transmission system, so that the cleaning component can realize the automatic cleaning function through gear transmission. The side of the second circular gear 14 away from the mounting block 13 is fixedly connected to the fan gear 15. The fan gear 15 is used to drive the fan gear 15 to rotate through the rotation of the second circular gear 14, and convert the rotational motion into linear motion. The lower parts of the left and right sides of the protective box 1 are fixedly connected to the brackets 18. The brackets The bracket 18 provides a good installation environment for other components. A conveying component is fixedly connected to the middle of the bracket 18. The conveying component is used to replace the air inside the protective box 1. A box body 24 is fixedly connected to the rear side of the protective box 1. The box body 24 is used to accommodate a cooling component. A cooling component is arranged inside the box body 24. The temperature inside the protective box 1 is reduced by cooling means to ensure that the power facilities can still operate safely and stably in a high temperature environment. Two plate condensers 29 are fixedly connected to the inner wall of the rear side of the protective box 1. The plate condenser 29 cools the gas or steam to cool the inside of the protective box 1.

[0028] The cleaning assembly includes four fixed blocks 8, which are the basic structure of the cleaning system and are responsible for supporting and positioning related components to ensure that they can operate stably during the cleaning process. The four fixed blocks 8 are fixedly connected to the upper and lower sides of the dust cover 7 to form a stable support structure to ensure stability during work. A fixed rod 9 is fixedly connected between two adjacent fixed blocks 8. The fixed rod 9 not only enhances the connection strength between the fixed blocks 8, but also provides a guide rail for the sliding of the cleaning plate 10 to ensure that it can move smoothly. Two cleaning plates 10 are slidably connected to the outside of the fixed rod 9. The cleaning plate 10 can be moved in the dust cover 7 through a sliding mechanism. The surface of the dust cover 7 performs reciprocating motion, thereby achieving effective cleaning of the surface of the dust cover 7. A rack plate 11 is fixedly connected between the two cleaning plates 10. The reciprocating sliding of the rack plate 11 drives the cleaning plate 10 to slide reciprocatingly to clean the surface of the dust cover 7. A spring 12 is sleeved on the upper outer part of the fixed block 8. The spring 12 is used to reset when subjected to external pressure, pushing the rack plate 11 to reset. A connecting plate 16 is fixedly connected to the outer side of the bottom cleaning plate 10. The connecting plate 16 is used to install the connecting rod 17. The bottom of the connecting plate 16 is fixedly connected to the connecting rod 17. The connecting rod 17 is used to transmit the movement of the connecting plate 16.

[0029] The first circular gear 5 and the second circular gear 14 are meshed to transmit the power generated by the fan 3 to the cleaning component, so that it can automatically perform cleaning operations. The fan gear 15 and the rack plate 11 are meshed to ensure that the cleaning plate 10 can move in a straight line, so that the cleaning plate 10 can efficiently clean the surface of the dust cover 7. One end of the spring 12 is fixedly connected to the bottom of the upper fixing block 8, and the other end of the spring 12 is fixedly connected to the upper part of the upper cleaning plate 10, providing an upward elastic force to ensure that the cleaning plate 10 always maintains a certain pressure to achieve an effective cleaning effect.

[0030] The conveying assembly includes a cylinder 19, which is the core part of the conveying system and is responsible for accommodating and guiding the flow of materials inside to ensure that the materials can be smoothly transported to the predetermined position. The outer side of the cylinder 19 is fixedly connected to the middle of the bracket 18 to ensure the stability of the cylinder 19 and prevent it from being displaced or tilted during operation. A piston 20 is slidably connected to the inside of the cylinder 19. The function of the piston 20 is to promote the flow of materials inside the cylinder 19 through reciprocating motion to achieve an effective conveying function. Two one-way valves 21 are fixedly connected to the bottom of the cylinder 19. The one-way valve 21 can control the flow direction of the material to ensure that the material flows in only one direction to prevent backflow, thereby improving the conveying efficiency. The bottom of the front one-way valve 21 is fixedly connected to an air inlet pipe 22 for introducing gas into the protective box 1. The bottom of the rear one-way valve 21 is fixedly connected to an air outlet pipe 23 for introducing gas into the cylinder 19 to ensure the stability and cleanliness of the internal environment.

[0031] One end of the connecting rod 17 away from the connecting plate 16 passes through the upper side of the cylinder 19 and is fixedly connected to the upper side of the piston 20, so that the piston 20 can generate up and down movement through the up and down movement of the connecting rod 17 to inhale and discharge the gas inside the cylinder 19.

[0032] The cooling component includes multiple mounting frames 25, which provide a stable support for the cooling equipment to ensure that it remains stable during operation. The mounting frame 25 is internally rotatably connected to an impeller 26, which is used to generate rotation through the flow of gas. The impeller 26 is fixedly connected to a rotating shaft 27 on the side away from the mounting frame 25. The rotating shaft 27 provides support for the rotation of the impeller 26 and transmits the rotational power to other related components. The rotating shaft 27 is fixedly connected to a fan 28 on the side away from the impeller 26. The fan 28 generates rotation through the rotation of the rotating shaft 27 to discharge the gas into the protective box 1.

[0033] One end of the air inlet pipe 22 away from the one-way valve 21 passes through the protective box 1 and is arranged inside the protective box 1, ensuring that the gas inside the protective box 1 can smoothly enter the cylinder 19 for replacement. The one end of the air outlet pipe 23 away from the one-way valve 21 passes through the mounting frame 25 and is arranged inside the mounting frame 25, ensuring that the gas inside the cylinder 19 can be discharged smoothly and maintain good air circulation.

[0034] The front side of the protective box 1 is rotatably connected to two box doors 2, which can be easily opened and closed, making it easy to maintain and inspect the equipment inside the box and improving the convenience of use. A handle is provided on the front side of the box door 2 to facilitate users to easily open and close the box door 2 when needed, thereby improving the comfort and convenience of operation.

[0035] Working principle: when it is necessary to protect the power facilities, the power facilities are installed inside the protection box 1, and the two fans 3 are started. The fan 3 rotates to drive the reducer 4 to rotate, and the reducer 4 rotates to drive the first circular gear 5 to rotate. The first circular gear 5 and the second circular gear 14 are meshed. Therefore, the first circular gear 5 rotates to drive the second circular gear 14 to rotate, and the second circular gear 14 rotates to drive the fan gear 15 to rotate. The fan gear 15 and the rack plate 11 are meshed. The fan gear 15 rotates to drive the rack plate 11 to slide. When the rack plate 11 slides upward, it will drive the two cleaning plates 10 to slide upward. At the same time, the spring 12 is squeezed by the cleaning plate 10. Because the fan gear 15 is fan-shaped, when the fan gear 15 rotates to the other side, the spring 12 will be reset due to being squeezed, thereby pushing the cleaning plate 10 to slide downward, so as to clean the outside of the dust cover 7. During the sliding process, the cleaning plate 10 will also drive the connecting plate 16 to slide, and further drive the connecting rod 17 to slide. The sliding of the connecting rod 17 drives the piston 20 to slide. When the piston 20 slides, the air pressure inside the cylinder 19 will change. When the air pressure inside the cylinder 19 increases, the gas inside the protection box 1 will be sucked into the cylinder 19 through the action of the front one-way valve 21 and the air inlet pipe 22. When the air pressure at the bottom of the cylinder 19 decreases, the gas inside the cylinder 19 will be discharged through the action of the rear one-way valve 21 and the air outlet pipe 23. When the gas is discharged, the impeller 26 is driven to rotate under the action of the air outlet pipe 23. The impeller 26 rotates, further driving the rotating shaft 27 and the fan 28 to rotate, and the gas is discharged for a second time. The secondary discharged gas will be cooled under the action of the plate condenser 29, further reducing the temperature inside the protection box 1, ensuring that the electrical components inside the protection box 1 will not be damaged due to high temperature.
