[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Embodiment: The present invention provides a mobile power conversion equipment ventilation device, such as Figures 1 to 4As shown, it includes a transformer body 1, and two partitions 2 are fixedly connected inside the transformer body 1. Ventilation slots are connected on both sides of the inner wall of the transformer body 1 and located between the two partitions 2. Exhaust ports are connected on both sides of the inner wall of the transformer body 1 and located directly below the ventilation slots. A plurality of inclined plates 3 are fixedly connected inside each exhaust port, and air also enters the transformer body 1 from the exhaust port through the inclined plates 3, so that the air circulates inside the transformer body 1 and improves the ventilation effect inside the transformer body 1. The top of each ventilation slot is rotatably connected to a rotating shaft 4, and the surface of each rotating shaft 4 is fixedly connected to a first box door 5. When in use, the first box doors 5 on both sides are rotated open by the rotating shaft 4, and each first box door 5 is opened. Both sides of the bottom end of a box door 5 are rotatably connected with a first support rod 6, and both sides of each ventilation slot are rotatably connected with a second support rod 7. The second support rod 7 is rotatably connected to the first support rod 6. When the first box door 5 rotates, the second support rod 7 and the first support rod 6 will gradually change from an inverted "V" to a horizontal state. The top of the first support rod 6 is rotatably connected to a side close to the second support rod 7, and then the cross plate is rotated to block the second support rod 7 through the cross plate, thereby supporting the first box door 5. The two end surfaces of each rotating shaft 4 are fixedly connected with a first gear 8, and winding wheels 9 are provided on both sides of the top end of each ventilation slot. One side of each winding wheel 9 is fixedly connected to a second gear 10, and the second gear 10 is rotatably connected to the first gear 8. The gears 8 are meshed with each other, and when the rotating shaft 4 rotates, the first gear 8 is also driven to rotate, thereby causing the second gear 10 to rotate with the winding wheel 9 to lower the rope 12. The two opposite surfaces of the two partitions 2 are slidably connected with racks 11 at both ends, and the surface of each winding wheel 9 is wound with a rope 12, so that the rack 11 gradually descends, and one end of each rope 12 is fixedly installed on the top of the rack 11. A rotating mechanism is provided at the bottom end of the transformer body 1, and the ventilation effect of the transformer body 1 can be increased by the rotating mechanism. The second box door is hinged on both sides of the transformer body 1. The interior of the transformer body 1 is divided into three cavities by two partitions 2. The left side is a high-voltage chamber, the middle is a transformer chamber, and the right side is a low-voltage chamber. Each partition 2 are connected with a plurality of round holes on the top. When in use, the first boxes 5 on both sides are opened by rotating the first boxes 5 through the rotating shaft 4. When the first boxes 5 are rotated, the second support rod 7 and the first support rod 6 will gradually change from an inverted "V" to a horizontal state, and then the cross plate is rotated to block the second support rod 7 through the cross plate, so as to support the first boxes 5. When the rotating shaft 4 rotates, the first gear 8 is also driven to rotate, and then the second gear 10 and the winding wheel 9 are rotated to lower the rope 12 and the rack 11 to descend, so that the rotating mechanism is opened, so that air can also enter the inside from the bottom of the transformer body 1, thereby improving the circulation and circulation of air inside the transformer body 1, and thus improving the ventilation effect.

[0031] like Figure 5 As shown, the rotating mechanism includes: a rotating plate 15, placement grooves are provided on both sides of the bottom end of the transformer body 1, and a plurality of through grooves are provided on both sides of the bottom end of the inner wall of the transformer body 1, and are all connected with the placement grooves. The rotating plate 15 is hinged in the placement groove, and pressure plates 13 are slidably connected on both sides of the inner wall of the transformer body 1 and located at the bottom end of the rack 11. The bottom end of each pressure plate 13 is fixedly connected with a connecting rod 14, and a connecting piece is rotatably connected between the bottom end of each connecting rod 14 and the top end of one side of the rotating plate 15. The surface of each connecting rod 14 is sleeved with a first spring. When the rack 11 descends, the pressure plate 13 will be squeezed to make it descend, thereby causing the connecting rod 14 to descend, so that one side of the rotating plate 15 rotates downward, so that air can enter the interior of the transformer body 1 through the placement groove and the through groove.

[0032] like Figures 6 to 8 As shown, both sides of the inner wall of the transformer body 1 and between the two partitions 2 are slidably connected with filter screens 17, and both sides of each filter screen 17 are fixedly connected with a plurality of teeth 18, and the inner wall of the transformer body 1 and between the teeth 18 and the rack 11 are rotatably connected with a third gear 16, and the third gear 16 is meshed with the rack 11 and the teeth 18. When the rack 11 descends, the third gear 16 will rotate accordingly, so that the teeth 18 drive the filter screen 17 to rise, thereby filtering the air entering the ventilation slot, so that clean air enters the transformer body 1, and each third gear 16 is rotatably connected with a connecting plate 19 on one side away from the transformer body 1, and an L-shaped frame 20 is fixedly connected to the inner wall of the transformer body 1 and directly below the third gear 16, and each L-shaped frame 20 is slidably connected with a lifting block 21 on one side close to the third gear 16, and a second spring is fixedly connected between the bottom end of each lifting block 21 and the L-shaped frame 20 The other end of the connecting plate 19 is rotatably mounted on the lifting block 21. An arc plate 22 is fixedly connected to one side of each lifting block 21 and located above the connecting plate 19. A rubber ball 23 is fixedly connected to both sides of the inner wall of the transformer body 1 and located above the arc plate 22. A metal frame is provided on the outer wall of each filter 17. A plurality of teeth 18 are equidistantly arranged. When the rack 11 descends, the third gear 16 will rotate accordingly, so that the teeth 18 drive the filter 17 to rise, thereby filtering the air entering the ventilation slot, so that clean air enters the transformer body 1. When the third gear 16 rotates, it will also pull the connecting plate 19, so that the connecting plate 19 moves up and down back and forth, and the lifting block 21 is pulled up and down by the connecting plate 19, so that the connecting plate 19 continuously squeezes the rubber ball 23 through the arc plate 22, so that it continuously contacts and collides with the metal frame of the outer wall of the filter 17, so that the surface of the filter 17 will not be blocked by dust.

[0033] like Figure 7As shown, both sides of the transformer body 1 and below the ventilation slots are connected with collecting slots, and each collecting slot is slidably connected with a collecting box 24. The top of the inner wall of the collecting box 24 near the filter 17 is set as a downward inclined surface, and each collecting slot is near the filter 17 and above the collecting box 24. A brush 25 is fixedly connected, and one side of the brush 25 is in contact with the filter 17. Limiting blocks are inserted on both sides of the bottom end of each collecting slot, and one side of each limiting block is in contact with the outer wall of one side of the collecting box 24. Dust dropped when the filter 17 vibrates will fall into the collecting box 24. As the filter 17 rises and falls, its surface is cleaned twice by the brush 25, thereby effectively preventing dust from accumulating on the surface of the filter 17, thereby preventing the filter 17 from being blocked by dust.

[0034] like Fig. 9 As shown, each first box door 5 is connected to a cavity inside, and an extension plate 26 is slidably connected to the inside of each cavity. Both ends of the bottom end of each extension plate 26 are fixedly connected with abutment plates 27, and rectangular plates 28 are slidably connected on both sides of the bottom end of each cavity and directly below the extension plate 26. A third spring is fixedly connected between the rectangular plate 28 and the bottom end of the cavity. When it rains, the extension plate 26 is pulled outward and the rectangular plates 28 on both sides are squeezed outward by the abutment plates 27, thereby increasing the area of ​​the first box door 5, thereby increasing the shielding area and preventing rainwater from entering the inside of the substation equipment body 1 through the ventilation slots.

[0035] Working principle: When in use, the first box doors 5 on both sides are opened by rotating the rotating shaft 4. When the first box door 5 rotates, the second support rod 7 and the first support rod 6 will gradually change from an inverted "V" to a horizontal state, and then the cross plate is rotated to block the second support rod 7 through the cross plate, thereby supporting the first box door 5. When the rotating shaft 4 rotates, the first gear 8 is also driven to rotate, thereby causing the second gear 10 and the winding wheel 9 to rotate to lower the rope 12, so that the rack 11 descends, the pressure plate 13 is squeezed to make it descend, and then the connecting rod 14 descends, so that one side of the rotating plate 15 rotates downward, so that air can also enter the interior from the bottom of the substation body 1, thereby improving the flow and circulation of air inside the substation body 1, thereby improving the ventilation effect.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
