Since the threaded shaft 6 is threadedly connected to the cleaning plate 7, and the outer wall of the cleaning plate 7 is in contact with the inner wall of the cabinet 1 and one side of the outer wall of the filter body 3, the rotation of the threaded shaft 6 drives the cleaning plate 7 to move back and forth, thereby cleaning the dust on the inner wall of the cabinet 1 and the surface of the filter body 3, which can not only solve the problem of dust clogging the filter body 3, but also clean the dust on the inner wall of the cabinet 1, thereby not only keeping the cabinet 1 clean, but also ensuring that the heat dissipation efficiency and effect of the cabinet 1 are not easily reduced.

[0019] Square through grooves 9 are provided on opposite sides of the outer wall of the cleaning plate 7; one end of the outer wall of a pair of rotating rods 8 is rotatably connected to the center of one side of the inner wall of a pair of square through grooves 9; the opposite end of the outer wall of a pair of rotating rods 8 passes through the cleaning plate 7; the outer side wall of one end of a pair of rotating rods 8 passing through the cleaning plate 7 is fixedly connected to a first gear 10; an auxiliary plate 11 is fixedly connected to one end of the outer wall of a pair of rotating rods 8 that does not pass through the cleaning plate 7, and the pair of auxiliary plates 11 are matched with the inner side wall of the cabinet 1; gear strips 12 are slidably connected to opposite sides of the inner wall of the cleaning plate 7, and a pair of gear strips 12 are respectively meshed with a pair of first gears 10; the gear strip 12 matches the cabinet 1, and when the cabinet 1 is cleaned, one side of the inner wall of the cabinet 1 and one side of the inner wall of the cabinet door 2 will move the gear strip 12 clamps, so that the gear bar 12 is not easy to move. At this time, when the cleaning plate 7 moves under the rotation of the threaded shaft 6, the cleaning plate 7 will drive the rotating rod 8, the first gear 10 and the auxiliary plate 11 to move. Because a pair of gear bars 12 are respectively engaged with a pair of first gears 10, the first gear 10 moves, while the gear bar 12 remains relatively stationary, and the gear bar 12 is slidably connected to the inner wall of the cleaning plate 7, so that the first gear 10 will rotate due to the gear bar 12 when moving, so that the first gear 10 drives the rotating rod 8 to rotate, so that the rotating rod 8 drives the auxiliary plate 11 to rotate, and the rotation of the auxiliary plate 11 further improves the cleaning range and cleaning efficiency of the cleaning plate 7, so that the device not only has a faster cleaning speed, but also has a better cleaning efficiency.

[0020] The cleaning plate 7 includes a square plate 701 and a sliding plate 702; the sliding plate 702 is in an inverted L shape; sliding grooves 21 are provided at both ends of the outer wall of the square plate 701; the outer walls of a pair of sliding plates 702 are respectively slidably connected to the inner walls of a pair of sliding grooves 21; the inner walls of a pair of sliding grooves 21 are provided with adjustment plates 22; springs 23 are fixedly connected to the opposite sides of the outer walls of the pair of adjustment plates 22, and one end of the outer wall of the pair of springs 23 is respectively fixedly connected to one end of the outer wall of the pair of sliding plates 702. By the cleaning plate 7 including the square plate 701 and the sliding plate 702, the cleaning plate 7 can be telescopically adjusted according to the size of the cabinet 1. When the cleaning plate 7 is in contact with the inner wall of the cabinet 1 for a long time and is thus worn, the elastic force of the spring 23 will cause the sliding plate 702 to continue to fit the inner wall of the cabinet 1, so that the cleaning mechanism on the sliding plate 702 maintains the best cleaning effect, thereby increasing the service life of the device and also enabling the device to maintain the best cleaning effect for a long time.

[0021] A pair of second through grooves 24 are provided on one side of the outer wall of the square plate 701, and the pair of second through grooves 24 are respectively connected to the pair of sliding through grooves 21; the adjusting plate 22 is convex in shape, and the outer side walls of the pair of adjusting plates 22 are respectively slidably connected to the inner side walls of the pair of sliding through grooves 21 and the pair of second through grooves 24; a pair of first threaded rods 25 are rotatably connected to one side of the outer wall of the square plate 701 through a pair of first square plates, and one end of the outer wall of the pair of first threaded rods 25 passes through the pair of adjusting plates 22 respectively, and the pair of first threaded rods 25 are respectively threadedly connected to the pair of adjusting plates 22; the pair of first threaded rods 25 are symmetrical about the center line of the square plate 701, and by rotating the first threaded rods 25, since the first threaded rods 25 are threadedly connected to the adjusting plate 22, the rotation of the first threaded rods 25 causes the adjusting plate 22 to move on the inner side of the sliding through grooves 21 and the second through grooves 24 The spring 23 is moved along the wall. When the adjusting plate 22 moves, the movement of the adjusting plate 22 will drive the spring 23 to move, so that the device can adjust the elastic force of the spring 23.

When the rotating rod 8 drives the auxiliary plate 11 to rotate, the rotation of the auxiliary plate 11 will drive the brush plate 15, the circular rod 14 and the second gear 16 to rotate around the rotating rod 8. Because the annular rack 18 and a pair of second gears 16 are meshed with each other, when the second gear 16 rotates around the rotating rod 8, the annular rack 18 will rotate, so that the second gear 16 drives the circular rod 14 to rotate, and the circular rod 14 drives the brush plate 15 to rotate, so that the brush plate 15 cleans the inner wall of the cabinet 1 and the filter body 3. The cleaning effect of the brush is better and it is easier to clean the dust on the filter body 3. The brush plate 15 not only rotates but also rotates around the rotating rod 8 while rotating, so that the cleaning effect and cleaning efficiency of the device are further improved. While the dust-proof effect of the device is better, the filter body 3 is not easy to accumulate dust on the surface under the rotation cleaning of the brush plate 15, thereby clogging the filter body 3, so that the heat dissipation effect and heat dissipation efficiency of the device are guaranteed.

[0023] A placement groove 26 is provided at the top of one side of the outer wall of the opening of the power cabinet; the outer wall of the placement plate 4 is slidably placed on the inner wall of the placement groove 26; one end of the outer wall of the motor 5 is arranged on one side of the outer wall of the placement plate 4; a threaded groove 27 is provided on one side of the outer wall of the placement plate 4; a bolt 28 is threadedly connected to one side of the outer wall of the cabinet 1, and one end of the outer wall of the bolt 28 passes through one side of the outer wall of the cabinet 1 and is located in the placement groove 26; the bolt 28 matches the threaded groove 27, and when the placement plate 4 and the cleaning plate 7 need to be taken out for cleaning, maintenance or replacement, the bolt 28 is rotated to move the bolt 28 out of the threaded groove 27, and the fixation of the placement plate 4 is released, and the placement plate 4 and the cleaning plate 7 and other machines are removed. The structure can be taken out, so that the device is not only convenient for repairing and cleaning the placement plate 4 and the cleaning plate 7, but also when the placement plate 4 or the cleaning plate 7 or other mechanisms are damaged, there is no need to replace the entire cabinet 1, only the placement plate 4 and the cleaning plate 7 need to be taken out for replacement, thereby reducing the replacement cost of the device, and the overall replacement of the cabinet 1 is relatively cumbersome, making its overall replacement not only troublesome, but also too time-consuming and labor-intensive. The dust removal and heat dissipation mechanism in the device is convenient for disassembly and installation, making the device more convenient and practical, and the placement plate 4 and the cleaning plate 7 are convenient for disassembly and installation, and the square plate 701 and the sliding plate 702 can adjust the distance, so that the scope of application of the device is increased.

[0024] Embodiment 2:

[0026] When the present invention is in use, the motor 5 drives the threaded shaft 6 to rotate. Since the threaded shaft 6 is threadedly connected to the cleaning plate 7, and the outer wall of the cleaning plate 7 is in contact with the inner wall of the cabinet 1 and one side of the outer wall of the filter body 3, the rotation of the threaded shaft 6 drives the cleaning plate 7 to move back and forth, thereby cleaning the dust on the inner wall of the cabinet 1 and the surface of the filter body 3, thereby not only solving the problem of dust blocking the filter body 3, but also cleaning the dust on the inner wall of the cabinet 1, thereby not only keeping the cabinet 1 clean, but also ensuring that the heat dissipation efficiency and effect of the cabinet 1 are not easily reduced. When the cabinet 1 is cleaned, one side of the inner wall of the cabinet 1 and one side of the inner wall of the cabinet door 2 will clamp the gear bar 12, making the gear bar 12 difficult to move. At this time, the cleaning plate 7 When the threaded shaft 6 rotates and moves, the cleaning plate 7 drives the rotating rod 8, the first gear 10 and the auxiliary plate 11 to move. Because the pair of gear bars 12 are respectively meshed with the pair of first gears 10, the first gear 10 moves, while the gear bars 12 remain relatively stationary, and the gear bars 12 are slidably connected to the inner wall of the cleaning plate 7, so that the first gear 10 rotates due to the gear bars 12 when moving, so that the first gear 10 drives the rotating rod 8 to rotate, so that the rotating rod 8 drives the auxiliary plate 11 to rotate, and the cleaning range and cleaning efficiency of the cleaning plate 7 are further improved through the rotation of the auxiliary plate 11, and when the rotating rod 8 drives the auxiliary plate 11 to rotate, the rotation of the auxiliary plate 11 drives the brush plate 15 and the circular rod 14 and the second gear 1 6 rotates around the rotating rod 8, because the annular rack 18 and a pair of second gears 16 are meshed with each other, when the second gear 16 rotates around the rotating rod 8, the annular rack 18 will rotate, so that the second gear 16 drives the circular rod 14 to rotate, and the circular rod 14 drives the brush plate 15 to rotate, so that the brush plate 15 cleans the inner wall of the cabinet 1 and the filter body 3, because the cleaning effect of the brush is better, and it is easier to clean the dust on the filter body 3, and the brush plate 15 not only rotates, but also rotates around the rotating rod 8 while rotating, so that the cleaning effect and cleaning efficiency of the device are further improved, so that the dustproof effect of the device is better, and the cleaning plate 7 includes a square plate 701 and a sliding plate 702, so that the cleaning plate 7 The telescopic adjustment can be performed according to the size of the cabinet 1. When the cleaning plate 7 is in contact with the inner wall of the cabinet 1 for a long time and is thus worn, the elastic force of the spring 23 will cause the sliding plate 702 to continue to fit the inner wall of the cabinet 1, so that the cleaning mechanism on the sliding plate 702 maintains the best cleaning effect, thereby increasing the service life of the device and allowing the device to maintain the best cleaning effect for a long time. By rotating the first threaded rod 25, since the first threaded rod 25 is threadedly connected to the adjustment plate 22, the rotation of the first threaded rod 25 causes the adjustment plate 22 to move on the inner wall of the sliding through groove 21 and the second through groove 24. When the adjustment plate 22 moves, the movement of the adjustment plate 22 drives the spring 23 to move, so that the elastic force of the spring 23 can be adjusted by the device.When the elastic force of the spring 23 is reduced due to long-term use, the elastic force of the spring 23 can be restored by rotating the first threaded rod 25, and the elastic force of the spring 23 can be adjusted by rotating the first threaded rod 25, so that the device can adjust the elastic force of the spring 23 according to the cleaning situation in the cabinet 1, so that the sliding plate 702 can be better attached to the inner wall of the cabinet 1, and the sliding plate 702 is not easy to be too tightly attached to the cabinet 1, which causes the sliding plate 702 to be seriously worn or the movement of the sliding plate 702 is more laborious, resulting in excessive power consumption and increased costs, thereby The device can make the sliding plate 702 operate normally while reducing its wear and energy consumption. When the rotating rod 8 rotates, the rotation of the pair of rotating rods 8 will drive the two groups of large fan blades 19 to rotate, so that the two groups of large fan blades 19 blow air and dissipate heat to the electrical components in the cabinet 1 from both sides of the cabinet 1. When the rotating rod 8 rotates, the circular rod 14 will rotate and rotate at the same time, so that a group of circular rods 14 will drive multiple groups of small fan blades 20 to rotate and blow air, and the multiple groups of small fan blades 20 will rotate around the rotating rod 8 while rotating, so that the blowing of the multiple groups of small fan blades 20 The wind range is increased, and the multiple groups of small fan blades 20 cooperate with the two groups of large fan blades 19 to further improve the heat dissipation efficiency and heat dissipation effect in the cabinet 1, so that the device not only has a dustproof function, but also has the effect of accelerating the heat dissipation of the cabinet 1. When it is necessary to take out the placement plate 4 and the cleaning plate 7 for cleaning, maintenance or replacement, the bolt 28 is rotated to move the bolt 28 out of the thread groove 27 to release the fixation of the placement plate 4. At this time, the placement plate 4 and the cleaning plate 7 and other mechanisms are taken out, so that the device is not only convenient for the maintenance and cleaning of the placement plate 4 and the cleaning plate 7, but also when the placement plate 4 and the cleaning plate 7 are taken out, the placement plate 4 and the cleaning plate 7 can be easily cleaned. When the plate 4 or the cleaning plate 7 or other mechanisms are damaged, there is no need to replace the entire cabinet 1. Only the placement plate 4 and the cleaning plate 7 need to be taken out for replacement, thereby reducing the replacement cost of the device. The overall replacement of the cabinet 1 is relatively cumbersome, making its overall replacement not only troublesome, but also too time-consuming and labor-intensive.
