[0033] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the present invention provides an embedded mobile power distribution cabinet, comprising a power distribution cabinet body 1, a cabinet door 2 and a wall 3, one side of the cabinet door 2 is hinged to one side of the front of the power distribution cabinet body 1, the outside of the power distribution cabinet body 1 is interlaced with the inside of the wall 3, a filter 4 is fixedly installed in the middle of the front of the cabinet door 2, a bracket 5 is fixedly installed on one side of the front of the cabinet door 2, and a heat dissipation cleaning mechanism is arranged inside the bracket 5;

[0034] The heat dissipation cleaning mechanism is composed of a frame 6, a motor 7, a threaded rod 8, a limit rod 9, two brushes 10 and three small fans 11. The motor 7 is fixedly installed inside the frame 6, and the frame 6 is fixedly installed on the right side of the top of the bracket 5.

[0035] Sliding mechanisms are provided on both sides of the bottom of the power distribution cabinet body 1.

The inner cavities of the two concave frames 13 are respectively connected to the outside of the two slide rails 12.

[0036] The tops of both sides of the front of the power distribution cabinet body 1 are provided with mounting grooves 14, the bottoms of the two mounting grooves 14 are provided with square grooves 15, and the two mounting grooves 14 are provided with connecting mechanisms, which are composed of a rotating drum 16, a screw rod 17 and a block 18;

[0037] Rectangular grooves 19 are provided in the middle of both sides of the distribution cabinet body 1, and circular holes 22 are provided at the top and bottom ends of the two rectangular grooves 19. Limiting plates 20 are inserted into the two rectangular grooves 19, and semicircular grooves 21 are provided on both sides of the top and bottom ends of the two limiting plates 20. Fixing mechanisms for fixing the limiting plates 20 are provided inside the four circular holes 22, and the four fixing mechanisms are composed of a telescopic rod 23, a hemispherical body 24 and a spring 25.

[0038] Among them, the output shaft of the motor 7 is fixedly connected to one end of the threaded rod 8, and the two ends of the threaded rod 8 are respectively connected to the right side of the top and bottom ends of the bracket 5 through bearings, and the outside of the threaded rod 8 is threadedly connected to one end of two brushes 10. Through the heat dissipation and cleaning mechanism, when the inside of the distribution cabinet body 1 needs to dissipate heat, people can control the rotation of the output shaft of the motor 7 to rotate the threaded rod 8, so that the two brushes 10 and three small fans 11 can be moved to the surface of the filter 4, so that when the fan is working, the outside wind can be blown into the inside of the distribution cabinet body 1 through the filter 4, thereby improving the heat dissipation effect, and when the surface of the filter 4 needs to be cleaned of dust, the output shaft of the motor 7 can be controlled to intermittently rotate forward and reverse, so that the two brushes 10 can move up and down with the rotation of the threaded rod 8 under the restriction of the limit rod 9, thereby cleaning the surface of the filter 4, thereby improving practicality.

[0039] Among them, the two ends of the limiting rod 9 are fixedly connected to the left side of the top and bottom ends inside the bracket 5 respectively, the outside of the limiting rod 9 is interlaced and connected with one end of the two brushes 10, and the top and bottom ends of the three brushes 10 are fixedly connected to the opposite sides of the two brushes 10 respectively. Through the restriction of the limiting rod 9, when the output shaft of the motor 7 rotates, the two brushes 10 can only move with the rotation of the threaded rod 8 but cannot rotate with the threaded rod 8.

[0040] Among them, the top ends of the two concave frames 13 are fixedly connected to the two sides of the bottom end of the distribution cabinet body 1, and the bottom ends of the two slide rails 12 are fixedly connected to the two sides of the bottom end of the inner cavity of the wall 3. A number of ball bearings 26 are respectively mounted on the top ends of the two slide rails 12, and the top ends of the several ball bearings 26 are respectively slidably connected to the top ends of the two concave frames 13. The ball bearings 26 can reduce the friction between the slide rails 12 and the concave frames 13, so that the distribution cabinet body 1 is easier to move.

[0041] Among them, the outsides of the two rotating cylinders 16 are respectively slidably connected with the insides of the two mounting grooves 14, and the insides of the two rotating cylinders 16 are provided with threads adapted to the screw rods 17. The insides of the two rotating cylinders 16 are respectively connected with the external threads of the two screw rods 17, and the tops of the two screw rods 17 are respectively connected with the two sides of the top of the inner cavity of the wall 3. Through the connecting mechanism, people can rotate the two rotating cylinders 16 so that the two screw rods 17 move with the rotation of the two rotating cylinders 16 under the restrictions of the two blocks 18 and the two square grooves 15, so that the tops of the screw rods 17 can be separated from the two sides of the top of the inner cavity of the wall 3, so that people can pull the distribution cabinet body 1 out of the inner cavity of the wall 3, which increases people's operating space and facilitates people's operation.

[0042] Among them, the bottom ends of the two screw rods 17 are fixedly connected to the middle parts of the top ends of the two blocks 18, and the outsides of the two blocks 18 are slidingly connected to the insides of the two square grooves 15. Through the restrictions of the blocks 18 and the square grooves 15, when the rotating drum 16 rotates, the screw rods 17 can only move up and down but cannot rotate with the rotating drum 16.

[0043] Among them, one end of the four telescopic rods 23 is fixedly connected to one end of the inside of the four circular holes 22, and the other ends of the four telescopic rods 23 are fixedly connected to the middle of one end of the four hemispheres 24, and the outside of the four hemispheres 24 are respectively connected with the inside of four semicircular grooves 21. Through the coordinated use of the fixing mechanism and the semicircular grooves 21, people can pull the limit plate 20 with force, and through the semicircular grooves 21 and the arc surfaces on the hemispheres 24, the semicircular grooves 21 can push the hemispheres 24 into the inside of the circular holes 22, so that the limit plate 20 can extend out of the rectangular groove 19 and can also be retracted into the inside of the distribution cabinet body 1. When the limit plate 20 is retracted into the inside of the distribution cabinet body 1, people can take the distribution cabinet body 1 out from the inside of the wall 3, which facilitates the installation and disassembly of the distribution cabinet body 1.

[0044] Among them, it is characterized in that four springs 25 are respectively arranged on the outside of the four telescopic rods 23, one end of the four springs 25 is respectively fixedly connected to one end of the inside of the four circular holes 22, and the other end of the four springs 25 is respectively fixedly connected to one end of the four hemispheres 24. Through the elastic force of the spring 25, when people do not pull the limit plate 20 hard, the hemisphere 24 can be inserted into the inside of one of the semicircular grooves 21 under the action of the elastic force of the spring 25 to fix the limit plate 20.

[0045] The motor 7 is electrically connected to an external driver, the driver is electrically connected to an external controller, the controller is electrically connected to an external power source, and the three small fans 11 are electrically connected to the external power source via an external switch.

[0046] During operation, first, when the inside of the power distribution cabinet body 1 needs to be cooled, the output shaft of the motor 7 is controlled to rotate, so that the output shaft of the motor 7 drives the threaded rod 8 to rotate, and the two brushes 10 move with the rotation of the threaded rod 8 under the restriction of the limit rod 9. When it moves to the middle of the filter 4, the output shaft of the motor 7 is controlled to stop rotating, and the power of the three small fans 11 is turned on, so that the three small fans 11 blow air to the inside of the power distribution cabinet body 1 to dissipate heat. When heat dissipation is not required, the power of the three small fans 11 is turned off. When the surface of the filter 4 needs to be cleaned, The output shaft of the control motor 7 is intermittently rotated, so that the two brushes 10 are intermittently moved up and down to clean the surface of the filter screen 4. After cleaning, the two brushes 10 are controlled to move to the top of the filter screen 4, and the output shaft of the control motor 7 stops rotating. When people need to inspect the inside of the distribution cabinet body 1, the two rotating drums 16 are rotated, so that the two screw rods 17 move downward with the rotation of the two rotating drums 16 under the restriction of the two blocks 18 and the two square grooves 15, and are separated from the two sides of the top of the inner cavity of the wall 3, and the distribution cabinet body 1 is pulled to make the distribution cabinet body 1 extends out of the wall 3, the two concave frames 13 slide on the two slide rails 12, and the cabinet door 2 is opened to inspect the electrical components inside the power distribution cabinet body 1. When the inspection is completed, the cabinet door 2 is closed, and the power distribution cabinet body 1 is pushed into the wall 3, and the two rotating cylinders 16 are rotated in the opposite direction. The two rotating cylinders 16 drive the two screw rods 17 to move upward and insert them into the two sides of the top of the inner cavity of the wall 3 respectively. When people need to remove the power distribution cabinet body 1 from the inside of the wall 3, repeat the above operation to pull the power distribution cabinet body 1 out of the wall 3, open the cabinet door 2, and push it to the wall 3. The two limit plates 20 are pulled hard inside, and through the semicircular grooves 21 and the arc surfaces on the hemispherical bodies 24, four of the semicircular grooves 21 can push the four hemispherical bodies 24 into the four circular holes 22, so that the two limit plates 20 can be retracted into the inside of the distribution cabinet body 1. When the limit plates 20 are retracted into the inside of the distribution cabinet body 1, the four hemispherical bodies 24 are inserted into the inside of the other four semicircular grooves 21 under the action of the elastic force of the four springs 25, so that the limit plates 20 no longer block the distribution cabinet body 1, allowing people to take the distribution cabinet body 1 out from the inside of the wall 3.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
