[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention cleans the dust on the ventilation net by not touching the ventilation net and not cleaning the ventilation net when the brush barrel moves upward, but touching the ventilation net and cleaning the ventilation net when the brush barrel moves downward. Compared with the traditional up and down cleaning method, this cleaning method can better reduce the amount of dust floating in the air during the cleaning process, thereby reducing the possibility of entering the electrical equipment.

[0016] 2. During the upward movement of the first fixed rod, the elastic cloth is stretched upward simultaneously, thereby isolating the ventilation net from the interior of the frame box, reducing the possibility of dust floating in the frame box. Moreover, through the cooperation of the elastic cloth and the one-way cleaning effect of the cleaning component, during cleaning, the dust will always be between the ventilation net and the elastic cloth, further improving the blocking effect of the elastic cloth. Also, during the upward movement of the first fixed rod, the elastic cloth is pulled, causing the elastic cloth to unfold and shake off the dust on the elastic cloth, further realizing the function of automatically cleaning the dust on the surface of the elastic cloth. And the cleaned dust will slide through the inclined plate to the leakage groove and then slide out of the frame box, enabling the dust to be automatically discharged from the frame box, further facilitating the staff to handle and collect the dust cleaned from the ventilation net.

[0017] 3. Through the swing of the third curved rod, in cooperation with the up and down movement of the brush barrel, when the brush barrel moves upward, water is not sprayed. When the brush barrel moves downward after reaching the uppermost end, water is sprayed. At this time, in cooperation with the blocking effect of the elastic cloth, it further realizes that while using liquid to moisten the brush barrel and improve the cleaning effect on the ventilation net, it also reduces the dispersion effect of the atomized liquid in the air.

[0018] 4. By knocking on the surface of the ventilation net during the cleaning process, the ventilation net vibrates, further improving the cleaning effect on the dust on the surface of the ventilation net. And in cooperation with the atomized water spraying component, the blocking component and the cleaning component working together, it further has the following effects. First, only when the cleaning component works, the vibration relaxation component will work. At this time, the elastic cloth in the blocking component will also rise, further preventing the probability of dust floating in the air when patting the dust on the surface of the ventilation net. Second, through the setting of the flapping plate, it can also form an isolated effect together with the elastic cloth. During the operation of the atomized water spraying component, the atomized water is better isolated between the flapping plate and the elastic cloth, thereby further preventing the dispersion of the atomized water in the frame box. Third, also because the flapping plate is plate-shaped, through the setting of the flapping flapping plate, during the flapping process, a flowing wind will be generated, blowing the dust that has not been cleaned clean out of the ventilation net and falling outside the frame box, further improving the cleaning effect on the ventilation net.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1. Please refer to Figures 1 to 14 , this embodiment provides a technical solution: a switch cabinet for a transformer, including a frame box 1. A cleaning box 5 is fixedly connected to the outer surface of the frame box 1. A ventilation component is arranged inside the frame box 1, and the ventilation component includes: A ventilation net 8.

A leakage slot 9 is also opened on the side surface of the frame box 1, and the leakage slot 9 is arranged below the ventilation net 8.

[0023] More specifically, in this embodiment: Install electrical equipment such as a transformer in the switch cabinet, then close the door 3. Next, make the transformer and electrical equipment work inside the frame box 1. The heat generated by the transformer and electrical equipment during energized operation will be dissipated from the frame box 1 through the ventilation net 8, thereby achieving the purpose of heat dissipation. The setting of this ventilation component uses the ventilation net 8 to dissipate the heat generated by the transformer and electrical equipment working inside the frame box 1, thereby reducing the probability of damage to the transformer and electrical equipment inside the frame box 1 due to high temperature.

[0024] It should be noted that this embodiment also includes: An external component is arranged inside the frame box 1, and the external component includes: A heightening block 2, a door 3 and a handle 4. A through slot is opened on the surface of the frame box 1, and the side wall of the through slot is hinged to the surface of the door 3. The surface of the door 3 is connected to the surface of the handle 4. The upper surface of the heightening block 2 is connected to the lower surface of the frame box 1. A display screen 7 is also fixedly connected to the surface of the door 3.

[0025] More specifically, in this embodiment: The setting of the heightening block 2 allows a space to be formed between the bottom of the switch cabinet and the ground when using this switch cabinet, further preventing the possibility of short - circuit of the transformer and electrical equipment inside the switch cabinet on a damp ground. And through the settings of the door 3, the handle 4 and the display screen 7, it further facilitates the use of this electrical equipment, thereby improving the practicability of this switch cabinet.

[0026] Embodiment 2. On the basis of the above - mentioned embodiment: Please refer to Figures 1 to 14 , in this embodiment, it includes: A cleaning component is arranged inside the cleaning box 5, and the cleaning component includes: Fixing plate 1 - 24, handle 2 - 6 and rotating shaft 1 - 14. The end face of handle 2 - 6 is connected to the surface of rotating shaft 1 - 14. The surface of rotating shaft 1 - 14 rotates through the surface of cleaning box 5. The end face of fixing plate 1 - 24 is connected with fixing block 1 - 22. The end face of fixing block 1 - 22 is connected to the inner wall of cleaning box 5. One end of fixing plate 1 - 24 is provided with a through - hole. The groove wall of the through - hole is rotatably connected to the surface of rotating shaft 1 - 14. The end surface of the end of rotating shaft 1 - 14 away from handle 2 - 6 is fixedly connected with crank 1 - 23. The end face of crank 1 - 23 away from rotating shaft 1 - 14 is hinged to crank 2 - 20. The central end face of crank 2 - 20 is hinged to crank 3 - 17. One end of crank 3 - 17 away from crank 2 - 20 is rotatably connected to the surface of fixing plate 1 - 24. One end of crank 2 - 20 away from crank 3 - 17 is provided with a through - slot opening. The surface of the through - slot opening is fixedly connected with fixing rod 1 - 42. The surface of fixing rod 1 - 42 is rotatably connected with brush barrel 31.

[0027] More specifically, in this embodiment: When the frame box 1 is dissipated heat through the ventilation net 8 for a long time, a large amount of dust will accumulate on the surface of the ventilation net 8. These dusts will affect the heat dissipation effect of the ventilation net 8. Therefore, it is necessary to clean the ventilation net 8. During cleaning, the transformer and electrical equipment in the frame box 1 are powered off. Then, rotate handle 2 - 6 to drive rotating shaft 1 - 14 to rotate. The rotation of rotating shaft 1 - 14 will further drive crank 1 - 23 to rotate. The rotation of crank 1 - 23 will drive crank 2 - 20 to move. And through the restriction of crank 3 - 17, while further driving crank 3 - 17 to swing, it also makes crank 2 - 20 swing, so as to drive fixing rod 1 - 42 to have the following two motion states: First: When fixing rod 1 - 42 drives brush barrel 31 to move upward, at this time, crank 2 - 20 will drive fixing rod 1 - 42 to move in a curve similar to a semi - arc, so that when brush barrel 31 moves upward, it does not contact ventilation net 8; Second: When fixing rod 1 - 42 drives brush barrel 31 to move downward, at this time, crank 2 - 20 will drive fixing rod 1 - 42 to move straight downward, further making brush barrel 31 roll on the surface of ventilation net 8, so as to brush off the dust on ventilation net 8; By making brush barrel 31 not contact ventilation net 8 during the upward movement process and not perform cleaning operation on ventilation net 8, and making brush barrel 31 contact ventilation net 8 during the downward movement process and perform cleaning operation on ventilation net 8, the effect of one - way cleaning is achieved; The setting of this cleaning component is such that during the upward movement of the brush barrel 31, it does not contact the ventilation net 8 and does not perform a cleaning operation on the ventilation net 8. When the brush barrel 31 moves downward, it contacts the ventilation net 8 and performs a cleaning operation on the ventilation net 8 to clean the dust on the ventilation net 8. Compared with the traditional up-and-down cleaning method, this cleaning method can better reduce the amount floating in the air during the cleaning process, thereby reducing the possibility of entering the electrical equipment.

[0028] Embodiment 3, on the basis of the above embodiment: Please refer to Figures 1 to 14 , in this embodiment, it includes: a blocking component is arranged in the frame box 1, and the blocking component includes: The second fixing plate 40, the elastic cloth 32 and the inclined plate 33. The lower end surface of the elastic cloth 32 is connected to the upper surface of the inclined plate 33. The lower surface of the inclined plate 33 is connected to the inner wall of the frame box 1, and the side surface of the elastic cloth 32 is slidably connected to the inner wall of the frame box 1.

The surface of the first connecting block 48 abuts against the surface of the ventilation net 8.

[0029] More specifically, in this embodiment: during the upward movement of the first fixing rod 42, it will pull the elastic cloth 32 upward through the second fixing plate 40. And since the path of the first fixing rod 42 during the upward movement is an arc surface, it can further pull the elastic cloth 32, so that the elastic cloth 32 can be better unfolded, and thus the dust on the elastic cloth 32 can be better shaken off; The setting of this blocking component is such that during the upward movement of the first fixing rod 42, the elastic cloth 32 is simultaneously stretched upward, thereby isolating the ventilation net 8 from the inside of the frame box 1, and further reducing the possibility of dust floating in the frame box 1. And it also cooperates with the one-way cleaning effect of the cleaning component of the elastic cloth 32, so that during cleaning, the dust will always be between the ventilation net 8 and the elastic cloth 32, further improving the blocking effect of the elastic cloth 32. Also, during the upward movement of the first fixing rod 42, the elastic cloth 32 is pulled to make the elastic cloth 32 unfold, and the dust on the elastic cloth 32 is shaken off, which further realizes the function of automatically cleaning the dust on the surface of the elastic cloth 32. And the cleaned dust will slide through the inclined plate 33 to the leakage groove 9 and then slide out of the frame box 1, so that the dust can be automatically discharged from the frame box 1, which further facilitates the staff to handle and collect the dust cleaned from the ventilation net 8.

[0031] More specifically, in this embodiment: By rotating the handle two 6 to drive the rotating shaft one 14 to rotate, and further driving the curved rod three 17 to swing around the connection point of the fixing plate one 24 and the curved rod three 17 through the curved rod one 23 and the curved rod two 20, thereby driving the sliding column one 16 on the curved rod three 17 to slide in the arc-shaped sliding bracket 15, and then driving the arc-shaped piston 18 to slide in the arc-shaped piston cylinder 10 through the socket part 28. Further cooperation with the cleaning assembly has the following two motion states: One: When the brush cylinder 31 moves upward, at this time, the sliding column one 16 slides leftward in the arc-shaped sliding bracket 15, further driving the arc-shaped piston 18 to move in the arc-shaped piston cylinder 10 in a direction away from the bottom of the arc-shaped piston cylinder 10, and then cooperating with the check valve one 26 and the check valve two 27 to inject water into the arc-shaped piston cylinder 10; Second: when the brush barrel 31 moves to the uppermost end, at this time the brush barrel 31 contacts the surface of the ventilation net 8, and at this time the first sliding column 16 slides to the right in the arc-shaped sliding frame 15, further driving the arc-shaped piston 18 to move towards the bottom of the arc-shaped piston cylinder 10 in the arc-shaped piston cylinder 10. With the one-way fluidity of the first one-way valve 26 and the second one-way valve 27, the liquid in the arc-shaped piston cylinder 10 is sprayed out from the atomizing nozzle rod 47 through the first hose 19; With the setting of this atomizing water spraying assembly, through the swing of the third curved rod 17, and in cooperation with the up and down movement of the brush barrel 31, it is further realized that no water is sprayed when the brush barrel 31 moves upward, and when the brush barrel 31 moves downward after moving to the uppermost end, water is sprayed. At this time, with the blocking effect of the elastic cloth 32, it is further realized that while using the liquid to moisten the brush barrel 31 and improve the cleaning effect on the ventilation net 8, the effect of atomized liquid floating in the air is also reduced.

The end face of the gear ring 2 39 is connected to a flapping plate 30. The end face of the flapping plate 30 is provided with a penetrating rotating opening, and the groove wall of the rotating opening is rotatably connected to the surface of the fixed rod 2 44. The groove wall of the sliding frame 1 37 is provided with a limiting groove. The surface of the sliding column 2 36 that is slidably connected to the sliding frame 1 37 is fixedly connected with a square block, and the surface of the square block is slidably connected to the groove wall of the limiting groove, so that the sliding column 2 36 can only slide on the groove wall of the sliding frame 1 37 and cannot rotate.

[0033] More specifically, in this embodiment, when the curved rod 20 drives the fixed rod 1 42 to make an arc motion when ascending and a linear motion when descending, the following two motion states are provided: First, when the fixing rod 1 42 moves upward, due to the curved motion, the gear ring 1 41 and the straight tooth row 1 29 are further not engaged, and the flapping plate 30 is further not driven to flap the ventilation net 8; Second: When the first fixed rod 42 moves upward to the uppermost position and then moves downward, at this time, the first toothed ring 41 meshes with the tooth surface of the first straight tooth row 29. When the first fixed rod 42 moves downward, it will further drive the first toothed ring 41 to roll on the surface of the first straight tooth row 29, thereby causing the first toothed ring 41 to rotate. Further, it drives the triangular piece 43 to rotate clockwise, thereby continuously pushing the toggle frame 35 to swing around the second fixed rod 44. When the end of the toggle frame 35 close to the triangular piece 43 moves upward, under the restricting action of the first sliding frame 37, the second sliding column 36 in the sliding groove 49 will move towards the direction of the second fixed rod 44, further squeezing the first sliding block 51 and thus squeezing the first spring 50. At the same time, it drives the second sliding column 36 to slide in the first sliding frame 37, further driving the second straight tooth row 38 to move, thereby causing the second toothed ring 39 to rotate, driving the flapping plate 30 to rotate around the second fixed rod 44. When the triangular piece 43 disengages from one end of the toggle frame 35, the first spring 50 releases pressure, further driving the second sliding column 36 and the toggle frame 35 to return to their original positions. Further, it also drives the second sliding column 36 to return to its original position in the first sliding frame 37. Then, through the movement of the second straight tooth row 38, the second toothed ring 39 rotates in the reverse direction, thereby causing the flapping plate 30 to flap the surface of the ventilation net 8, making the surface of the ventilation net 8 vibrate and loosening the dust on the surface of the ventilation net 8; With the setting of this vibration and loosening component, by knocking on the surface of the ventilation net 8 during the cleaning process, the ventilation net 8 vibrates, further improving the cleaning effect of the dust on the surface of the ventilation net 8. And in cooperation with the atomizing water spraying component, the blocking component and the cleaning component working together, it further has the following effects. First, only when the cleaning component works, the vibration and loosening component will work. At this time, the elastic cloth 32 in the blocking component will also rise, further preventing the probability of dust floating in the air when flapping the dust on the surface of the ventilation net 8. Second, through the setting of the flapping plate 30, it can also jointly form an isolation effect with the elastic cloth 32. During the operation of the atomizing water spraying component, the atomized water is better isolated between the flapping plate 30 and the elastic cloth 32, thereby further preventing the atomized water from floating in the frame box 1. Third, also because the flapping plate 30 is plate-shaped, through the setting of flapping the flapping plate 30, further, during the flapping process, a flowing wind will be generated, blowing the dust that has not been cleaned clean out of the ventilation net 8 and falling outside the frame box 1, further improving the cleaning effect of the ventilation net 8.

[0034] Working principle: When this kind of switch cabinet for transformers is in use, it has the following steps: During cleaning, power off the transformer and electrical equipment in the framework box 1, then rotate the handle two 6 to drive the rotation shaft one 14 to rotate. The rotation of the rotation shaft one 14 will further drive the crank one 23 to rotate. The rotation of the crank one 23 will drive the crank two 20 to move, and through the restriction of the crank three 17, further drive the crank three 17 to swing. At the same time, the crank two 20 will also swing, thereby driving the fixed rod one 42 to have the following two motion states: First: When the fixed rod one 42 drives the brush barrel 31 to move upward, at this time, the crank two 20 will drive the fixed rod one 42 to move in a semi-circular curve, so that the brush barrel 31 does not contact the ventilation net 8 during the upward movement. During the upward movement of the fixed rod one 42, it will pull the elastic cloth 32 upward through the fixing plate two 40 to unfold the elastic cloth 32. At the same time, the sliding column one 16 slides to the left in the arc-shaped sliding frame 15, further driving the arc-shaped piston 18 to move away from the bottom of the arc-shaped piston cylinder 10 in the arc-shaped piston cylinder 10, and then cooperating with the one-way valve one 26 and the one-way valve two 27 to inject water into the arc-shaped piston cylinder 10, and making the gear ring one 41 and the straight tooth row one 29 not engage, further not driving the flapping plate 30 to flap the ventilation net 8; Second, when the fixed rod 42 drives the brush cylinder 31 to move downward, the curved rod 20 drives the fixed rod 42 to move downward in a straight line, further making the brush cylinder 31 roll on the surface of the ventilation net 8, thereby brushing off the dust on the ventilation net 8. At this time, the descent of the fixed rod 42 drives the elastic cloth 32 to gradually shrink, and when the brush cylinder 31 moves to the uppermost end, the brush cylinder 31 contacts the surface of the ventilation net 8, and the sliding column 16 slides to the right in the arc-shaped sliding frame 15, further driving the arc-shaped piston 18 to move toward the arc-shaped piston cylinder 10 in the arc-shaped piston cylinder 10. The bottom of the piston cylinder 10 moves, and the one-way flow of the one-way valve 1 26 and the one-way valve 27 is coordinated, so that the liquid in the arc piston cylinder 10 passes through the hose 19, and the liquid is sprayed out from the atomizing nozzle rod 47. At the same time, the tooth ring 1 41 is meshed with the tooth surface of the straight tooth row 29, and the fixed rod 1 42 moves downward, which will further drive the tooth ring 1 41 to roll on the surface of the straight tooth row 29, so that the tooth ring 1 41 rotates, and further drives the triangular piece 43 to rotate clockwise, thereby continuously pushing the toggle frame 35 to swing with the fixed rod 2 44 as the axis, so that when the toggle frame 35 moves upward near one end of the triangular piece 43, under the restriction of the sliding frame 1 37, the sliding column 2 36 in the sliding groove 49 will move toward the direction of the fixed rod 2 44. The sliding block 1 51 is moved, further squeezing the sliding block 1 51 and thus squeezing the spring 1 50, and at the same time driving the sliding column 2 36 to slide in the sliding frame 1 37, further driving the straight tooth row 2 38 to move, thereby causing the tooth ring 2 39 to rotate, and driving the flapping plate 30 to rotate around the fixed rod 2 44 as the axis. When the triangular piece 43 is separated from one end of the toggle frame 35, the spring 1 50 releases the pressure, further driving the sliding column 2 36 and the toggle frame 35 to recover, and further driving the sliding column 2 36 to recover in the sliding frame 1 37, and then through the movement of the straight tooth row 2 38, the tooth ring 2 39 rotates in the opposite direction, thereby causing the flapping plate 30 to flap the surface of the ventilation net 8, causing the surface of the ventilation net 8 to vibrate, loosening the dust on the surface of the ventilation net 8.
