[0014] As a further technical solution of the present invention, the first rotating shaft is connected to the cleaning box through internal and external threads.

[0015] As a further technical solution of the present invention, the cleaning box and the maintenance plate are connected by bolts.

[0016] A method for using a transformer cabinet circuit protection component comprises the following steps:

[0017] S1: When the substation cabinet is ventilated, the motor is started to drive the second rotating shaft to rotate, the second rotating shaft drives the first rotating shaft to rotate through the pulley group, and the rotation of the first rotating shaft drives the cooling fan to rotate for ventilation;

[0018] S2: At the same time, the rotation of the first rotating shaft drives the rotation of the cleaning box, and the rotation of the cleaning box drives the rotation of the first mounting shaft and the second mounting shaft, so that the cleaning tape rotates on one side of the filter, and the dust and mosquitoes on one side of the filter are stuck away.

[0019] S3: When the cleaning box is rotating, the moving rod slides inside the slide groove, and when the moving rod slides and contacts the protrusion, it slides toward the inside of the maintenance plate through its guide, and the movement of the moving rod drives the movement of the tooth block, and the movement of the tooth block drives the gear to rotate, and the rotation of the gear drives the rotation of the second connecting shaft, and the rotation of the second connecting shaft drives the rotation of the first connecting shaft, and the rotation of the first connecting shaft drives the rotation of the first installation shaft, so that the first installation shaft rewinds the cleaning tape and unfolds the unused part;

[0020] S4: When the moving rod slides toward the inside of the maintenance plate, the first spring is deformed to store elastic potential energy. When the moving rod is separated from the protrusion, the elastic potential energy is released by the first spring to move the moving rod back to its original position.

[0021] S5: When the moving rod moves to reset, the tooth block is forced to rotate to the inside of the moving rod, and at the same time, the second spring is forced to deform, and the elastic potential energy is released to rotate the tooth block to reset, so that the first mounting shaft does not rotate when the moving rod is reset, so as to ensure the stability of the cleaning tape after use.

[0022] S6: After use, the cleaning box is removed from the outer wall of the first rotating shaft by rotation for maintenance.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention is arranged by cooperating with a ventilation component and a cleaning component. When the substation cabinet is ventilated, the second rotating shaft is driven to rotate by starting the motor. The rotation of the second rotating shaft drives the first rotating shaft to rotate through the pulley group. The rotation of the first rotating shaft drives the heat dissipation fan to rotate for ventilation. At the same time, the rotation of the first rotating shaft drives the rotation of the cleaning box. The rotation of the cleaning box drives the rotation of the first installation shaft and the second installation shaft, so that the cleaning tape rotates on one side of the filter to stick to the mosquitoes on one side of the filter. The device first blocks most of the mosquitoes from entering the cabinet through the filter, and then sticks the mosquitoes attached to the surface of the filter through the cleaning tape, thereby ensuring the circuit protection effect of the substation cabinet.

[0025] 2. The present invention arranges a rotating assembly. When the cleaning box is rotating, the moving rod slides in the interior of the slide groove. When the moving rod slides and contacts the protrusion, it slides toward the interior of the maintenance plate through its guide. The movement of the moving rod drives the movement of the tooth block. The movement of the tooth block drives the gear to rotate. The rotation of the gear drives the rotation of the second connecting shaft. The rotation of the second connecting shaft drives the rotation of the first connecting shaft. The rotation of the first connecting shaft drives the rotation of the first installation shaft, so that the first installation shaft reels up the cleaning tape and unfolds the unused part to prevent the viscosity from decreasing after use and affecting the use effect. The cleaning tape is gradually unfolded and used to ensure the cleaning effect of the filter, thereby improving the circuit protection effect of the substation cabinet.

[0026] 3. The present invention provides a first guide plate. When the cleaning tape installed on the outer wall of the second mounting shaft is gradually unfolded and used, the first guide plate allows the cleaning tape to always fit one side of the filter screen, thereby ensuring the cleaning effect of the cleaning tape on mosquitoes or dust on the surface of the filter screen.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The cleaning assembly includes a cleaning box 10 arranged on one side of the filter 4, a maintenance plate 11 is installed on the top of the cleaning box 10, a cleaning tape 14 is arranged inside the cleaning box 10, and both ends of the cleaning tape 14 are respectively installed on the outer walls of the first mounting shaft 12 and the second mounting shaft 13, and the first mounting shaft 12 is rotatably connected to the cleaning box 10 through a rotating assembly.

[0039] The cleaning tape 14 is configured as an insect sticky tape, and the sticky side of the cleaning tape 14 faces the filter screen 4;

[0040] Through the setting of the ventilation component, when the substation cabinet is ventilated, the second rotating shaft 8 is driven to rotate by the motor 9, and the second rotating shaft 8 rotates through the pulley group 7 to drive the first rotating shaft 6 to rotate, and the rotation of the first rotating shaft 6 drives the cooling fan 5 to rotate for ventilation;

[0041] At the same time, the rotation of the first rotating shaft 6 drives the rotation of the cleaning box 10, and the rotation of the cleaning box 10 drives the rotation of the first mounting shaft 12 and the second mounting shaft 13, so that the cleaning tape 14 rotates on one side of the filter screen 4 to stick the mosquitoes on one side of the filter screen 4 away.

[0042] The device first blocks most mosquitoes from entering the cabinet 1 through the filter 4, and then removes the mosquitoes attached to the surface of the filter 4 through the cleaning tape 14, thereby ensuring the circuit protection effect of the transformer cabinet.

[0043] like Figures 1 to 7 As shown, the rotating assembly includes a first connecting shaft 17 fixedly installed on the top of the first mounting shaft 12, a second connecting shaft 18 is arranged on the outer wall of the first connecting shaft 17, the second connecting shaft 18 is rotatably installed inside the maintenance plate 11, a gear 19 is fixedly connected to the top of the second connecting shaft 18, a gear block 21 is meshingly connected to one side of the gear 19, the gear block 21 is evenly arranged on one side of the moving rod 20, one end of the moving rod 20 is slidably installed inside the slide groove 22, the slide groove 22 is opened inside the vent 3, and a protrusion 23 is fixedly installed inside the slide groove 22.

[0044] By setting the rotating assembly, when the cleaning box 10 is rotating, the moving rod 20 slides in the inside of the slide groove 22, and when the moving rod 20 slides and contacts the protrusion 23, it slides toward the inside of the maintenance plate 11 through its guide, and the movement of the moving rod 20 drives the movement of the tooth block 21, and the movement of the tooth block 21 drives the gear 19 to rotate, and the rotation of the gear 19 drives the rotation of the second connecting shaft 18, and the rotation of the second connecting shaft 18 drives the rotation of the first connecting shaft 17, and the rotation of the first connecting shaft 17 drives the rotation of the first installation shaft 12, so that the first installation shaft 12 reels the cleaning tape 14 and unfolds the unused part to prevent the viscosity from decreasing after use and affecting the use effect. The cleaning tape 14 is gradually unfolded and used to ensure the cleaning effect of the filter 4, thereby improving the circuit protection effect of the substation cabinet.

[0045] like Figure 6 As shown, the first connecting shaft 17 is slidably connected to the second connecting shaft 18 .

[0046] like Figure 4 and Figure 7 As shown, the moving rod 20 is slidably installed inside the maintenance plate 11 , and a first spring 24 is installed between the moving rod 20 and the maintenance plate 11 .

[0047] When the moving rod 20 slides toward the inside of the maintenance plate 11, the first spring 24 is deformed to store elastic potential energy. When the moving rod 20 is separated from the protrusion 23, the elastic potential energy is released by the first spring 24 to move the moving rod 20 back to its original position.

[0048] The first spring 24 cooperates with the protrusion 23 to make the moving rod 20 move back and forth.

[0049] like Figure 7 As shown, the tooth block 21 is rotatably mounted inside the moving rod 20 via a third rotating shaft 25 , and a second spring 26 is provided on one side of the tooth block 21 .

[0050] One side of the tooth block 21 is set as an inclined surface;

[0051] When the moving rod 20 moves to reset, the tooth block 21 is forced to rotate to the inside of the moving rod 20, and at the same time the second spring 26 is forced to deform and releases its elastic potential energy to rotate and reset the tooth block 21, so that the first mounting shaft 12 does not rotate when the moving rod 20 is reset, thereby ensuring the stability of the winding of the cleaning tape 14 after use.

[0052] like Figure 4 and Figure 6 As shown, a first guide plate 15 is provided inside the cleaning tape 14 , and the first guide plate 15 is fixedly installed inside the cleaning box 10 .

[0053] The first guide plate 15 is arranged on a side close to the filter 4. When the cleaning tape 14 installed on the outer wall of the second installation shaft 13 is gradually unfolded and used, the cleaning tape 14 is always in contact with one side of the filter 4 through the first guide plate 15 to ensure the cleaning effect of the cleaning tape 14 on mosquitoes or dust on the surface of the filter 4.

[0054] like Figure 6 As shown, a second guide plate 16 is provided inside the cleaning tape 14 , and the second guide plate 16 is fixedly installed inside the cleaning box 10 .

[0055] A certain angle and distance are set between the cleaning tape 14 and the first installation shaft 12 to prevent the cleaning tape 14 outside the second installation shaft 13 from adhering to each other after being rolled up.

[0056] like Figure 3 As shown, the first rotating shaft 6 is connected to the cleaning box 10 through internal and external threads.

[0057] The cleaning box 10 can be removed from the outer wall of the first rotating shaft 6 by rotating the cleaning box 10 for maintenance.

[0058] like Figure 3 and Figure 4 As shown, the cleaning box 10 and the maintenance plate 11 are connected by bolts.

[0059] The maintenance plate 11 is removed by bolts, and the cleaning tape 14 is maintained and replaced.

[0060] A method for using a transformer cabinet circuit protection component comprises the following steps:

[0061] S1: When the substation cabinet is ventilated, the motor 9 is started to drive the second rotating shaft 8 to rotate, and the rotation of the second rotating shaft 8 drives the first rotating shaft 6 to rotate through the pulley group 7, and the rotation of the first rotating shaft 6 drives the cooling fan 5 to rotate for ventilation;

[0062] S2: At the same time, the rotation of the first rotating shaft 6 drives the rotation of the cleaning box 10, and the rotation of the cleaning box 10 drives the rotation of the first mounting shaft 12 and the second mounting shaft 13, so that the cleaning tape 14 rotates on one side of the filter 4 to stick away the dust and mosquitoes on one side of the filter 4.

[0063] S3: When the cleaning box 10 is rotating, the moving rod 20 slides inside the slide groove 22. When the moving rod 20 slides and contacts the protrusion 23, it slides toward the inside of the maintenance plate 11 through the guide. The movement of the moving rod 20 drives the movement of the tooth block 21. The movement of the tooth block 21 drives the gear 19 to rotate. The rotation of the gear 19 drives the rotation of the second connecting shaft 18. The rotation of the second connecting shaft 18 drives the rotation of the first connecting shaft 17. The rotation of the first connecting shaft 17 drives the rotation of the first installation shaft 12, so that the first installation shaft 12 reels the cleaning tape 14 and unfolds the unused part.

[0064] S4: When the moving rod 20 slides toward the inside of the maintenance plate 11, the first spring 24 is deformed to store elastic potential energy. When the moving rod 20 is separated from the protrusion 23, the elastic potential energy is released by the first spring 24 to move the moving rod 20 back to its original position.

[0065] S5: When the moving rod 20 moves to reset, the tooth block 21 is forced to rotate to the inside of the moving rod 20, and at the same time, the second spring 26 is forced to deform, and the elastic potential energy is released to rotate the tooth block 21 to reset, so that the first installation shaft 12 does not rotate when the moving rod 20 is reset, so as to ensure the stability of the cleaning tape 14 after use.

[0066] S6: After use, the cleaning box 10 is rotated and removed from the outer wall of the first rotating shaft 6 for maintenance.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
