[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0028] See also Figure 1-Figure 5 The present invention provides a technical solution: a power distribution device, comprising a power distribution cabinet body 1, a cooling fan 11 is arranged on the front of the inner wall of the power distribution cabinet body 1, a dustproof net 12 is embedded on the left and right sides of the power distribution cabinet body 1, and also includes a rainproof device 2 and an anti-blocking device 3;

[0029] The rainproof device 2 includes four telescopic rods 21, a water collecting box 22, a filter 23, two guide inclined plates 24, a hinged rod 25, a baffle 26 and four L-shaped plates 27. The four telescopic rods 21 are respectively fixed at the four corners of the top of the distribution cabinet body 1, and the two guide inclined plates 24 are respectively fixed between the tops of the telescopic ends of the two telescopic rods 21. The water collecting box 22 is fixed between the two guide inclined plates 24. The filter 23 is fixed at the top of the water collecting box 22. The filter 23 will block impurities in the rainwater to prevent impurities from being deposited in the water collecting box 22. The four L-shaped plates 27 are respectively fixed on the left and right sides of the distribution cabinet body 1. On the side and right sides, the baffle 26 is slidably installed on the top of the L-shaped plate 27, and a spring is provided between the baffle 26 and the inner wall of the L-shaped plate 27, and the hinged rod 25 is hinged between the top of the baffle 26 and the bottom of the water collecting box 22. Rainwater will fall into the water collecting box 22, and the water collecting box 22 moves downward under the action of gravity. The water collecting box 22 pushes the hinged rod 25 to drive the baffle 26 to form a shielding protection at the dustproof net 12, thereby avoiding the problem of rainwater tilting and falling, and easily entering the distribution cabinet body 1 through the dustproof net 12, thereby reducing the probability of leakage accidents caused by electronic components in the distribution cabinet body 1 after contacting rainwater.

[0030] The rainproof device 2 also includes a cover plate 28, which is fixed to the bottom of the back side of the water collecting box 22, and the cover plate 28 is located above the cooling fan 11. Ten centimeters are left between the cover plate 28 and the air inlet of the cooling fan 11. The side of the baffle 26 is fixedly connected with an inclined plate 29. At the same time, the water collecting box 22 drives the cover plate 28 to cover the air inlet of the cooling fan 11, thereby avoiding the cooling fan 11 from sucking external humid air into the distribution cabinet body 1, causing the electrical components in the distribution cabinet body 1 to be damaged by moisture; water overflowing from the water collecting box 22 will be discharged to the two sides of the distribution cabinet body 1 through the guide inclined plate 24.

[0031] The anti-blocking device 3 includes two Z-shaped tubes 31, an L-shaped folded tube 32, a U-shaped frame 33, a scraper 34 and a spring plate 35. The two Z-shaped tubes 31 are respectively fixed on the left and right sides of the bottom of the water collecting box 22, and the Z-shaped tube 31 passes through the top of the distribution cabinet body 1. The Z-shaped tube 31 has a small inner diameter and is used to drain the water inside the water collecting box 22 after the rain stops. The L-shaped folded tube 32 is fixed at the bottom of the Z-shaped tube 31, and one end of the L-shaped folded tube 32 away from the Z-shaped tube 31 passes through the wall of the distribution cabinet body 1. The U-shaped frame 33 is fixed on the side of the Z-shaped tube 31 close to the wall of the distribution cabinet body 1. The spring plate 35 is arranged between the bottom of the U-shaped frame 33 and the outer wall of the dustproof net 12, and the scraper 34 is fixed inside the U-shaped frame 33. The scraper 34 contacts the outer wall of the dustproof net 12. As the rainwater inside the water collecting box 22 is continuously replenished and discharged, the water collecting box 22 drives the Z-shaped tube 31 to move up and down. The Z-shaped tube 31 drives the scraper 34 to scrape the surface of the dustproof net 12 through the U-shaped frame 33. The dustproof net 12 vibrates slightly and drives away the flying insects that fly to the dustproof net 12 on rainy days, thereby avoiding the problem of flying insects blocking the dustproof net 12 and affecting the heat dissipation of the distribution cabinet body 1.

[0032] When in use, when the distribution cabinet main body 1 is used on a rainy day, the guide inclined plate 24 will form a protection on the top of the distribution cabinet main body 1, thereby avoiding the problem that rainwater falling on the distribution cabinet main body 1 will cause corrosion to the distribution cabinet main body, and the rainwater will fall into the water collecting box 22. The filter screen 23 will block the impurities in the rainwater to avoid the impurities from being deposited in the water collecting box 22. The inclined plate is used to form a preliminary shielding for the dustproof net 12 at the initial stage of rain. When the rain increases, the amount of rainwater in the water collecting box 22 increases. As the amount of rainwater in the water collecting box 22 increases, the water collecting box 22 moves downward under the action of gravity, and the water collecting box 22 pushes the hinged rod 25 to drive the baffle 26 to slide along the top of the L-shaped plate 27. The baffle 26 is away from the outer wall of the distribution cabinet main body 1, so that the baffle 26 is formed at the dustproof net 12. Continuous shielding and protection for a long time can achieve a stronger protection effect, thereby preventing rain from tilting and falling, and easily entering the distribution cabinet body 1 through the dustproof net 12, thereby reducing the probability of leakage accidents caused by electronic components in the distribution cabinet body 1 coming into contact with rain; at the same time, the water collecting box 22 drives the cover 28 to move downward, and the cover 28 moves to the air inlet of the cooling fan 11, and the cover 28 blocks the air inlet of the cooling fan 11, thereby preventing the cooling fan 11 from sucking external humid air into the distribution cabinet body 1, causing the electrical components in the distribution cabinet body 1 to be damaged by moisture. At the same time, since there is a ten-centimeter gap between the cover 28 and the air inlet of the cooling fan 11, the cover 28 will not affect the blowing and heat dissipation function of the cooling fan 11.

[0033] At the same time, the water collecting box 22 pushes the Z-shaped tube 31 to move downward, and the L-shaped folded tube 32 is squeezed and compressed by the Z-shaped tube 31. The L-shaped folded tube 32 and the Z-shaped tube 31 will continue to slowly discharge the rainwater in the water collecting box 22. When the rainwater in the water collecting box 22 becomes less, under the elastic force of the telescopic rod 21, the telescopic rod 21 pushes the water collecting box 22 to move upward. Since the opening of the water collecting box 22 is much larger than the drainage port of the Z-shaped tube 31, in heavy rain weather, the water intake per unit time of the water collecting box 22 is much larger than the drainage volume of the Z-shaped tube 31. Therefore, as the rainwater inside the water collecting box 22 is continuously replenished in large quantities and discharged in small quantities, the gravity of the water collecting box 22 will continue to increase. The replenishment and drainage process of the water collecting box 22 is not a dynamic balance, and the water overflowing from the top of the water collecting box 22 will be discharged through the diversion The inclined plate 24 is discharged to both sides of the distribution cabinet body 1. At the same time, the falling rainwater also carries a certain impact force. Under the impact force of rainwater and the change of gravity, the water collecting box 22 will move up and down, and the water collecting box 22 will drive the Z-shaped tube 31 to move, and the Z-shaped tube 31 will drive the U-shaped frame 33 to move, and the U-shaped frame 33 will drive the scraper 34 to scrape the surface of the dustproof net 12. The dustproof net 12 vibrates slightly and drives away the flying insects that fly to the dustproof net 12 on rainy days, thereby avoiding the problem of flying insects blocking the dustproof net 12 and affecting the heat dissipation of the distribution cabinet body 1. Since water passes through the L-shaped folded tube 32 and the Z-shaped tube 31, the air at the L-shaped folded tube 32 and the Z-shaped tube 31 will become cold, thereby improving the heat dissipation performance of the distribution cabinet body 1 on rainy days.

[0034] See also Figure 1-Figure 8 Based on the first embodiment, this embodiment further includes a sealing device 4 and an insect repellent device 5;

[0035] The insect repellent device 5 includes an insect repellent box 51, two elastic pressing members 52, a spraying pipe 53, and two U-shaped slide plates 54. The insect repellent box 51 is fixed to the bottom of the inner wall of the power distribution cabinet body 1, the two elastic pressing members 52 are fixed to the top of the insect repellent box 51, and the two U-shaped slide plates 54 are respectively fixed to the sides of the two elastic pressing members 52 away from each other. The U-shaped slide plate 54 contacts the outer wall of the spring plate 35, and the spraying pipe 53 is fixed to the bottom of the side of the dustproof net 12 away from the power distribution cabinet body 1. The spraying pipe 53 is in contact with the insect repellent. The agent boxes 51 are connected by a hose, and the elastic pressing piece 52 is used to control the insect repellent in the insect repellent box 51 to be sprayed out from the spray pipe 53. The Z-shaped tube 31 pushes the U-shaped frame 33 to squeeze the spring plate 35. The spring plate 35 bulges and deforms and pushes the U-shaped slide plate 54 to squeeze the elastic pressing piece 52. The elastic pressing piece 52 squeezes the insect repellent in the insect repellent box 51 to be sprayed out from the spray pipe 53. The insect repellent drives away and kills the flying insects at the dustproof net 12, thereby reducing the probability of the flying insects blocking the dustproof net 12.

[0036] The insect repellent device 5 also includes an elastic protrusion plate 55 and an arc rod 56. The elastic protrusion plate 55 is fixed on the side of the dustproof net 12 close to the distribution cabinet body 1, and the arc rod 56 is fixed on the side of the elastic protrusion plate 55 close to the U-shaped slide plate 54. The end of the arc rod 56 away from the elastic protrusion plate 55 contacts the outer wall of the dustproof net 12. A protrusion is fixed on the side of the elastic protrusion plate 55 close to the U-shaped slide plate 54. The protrusion of the elastic protrusion plate 55 is located on the movement trajectory of the U-shaped slide plate 54. At the same time, the U-shaped frame 33 pushes the spring plate 35 to drive the U-shaped slide plate 54 to move back and forth left and right. The U-shaped slide plate 54 pushes the elastic protrusion plate 55 to drive the arc rod 56 to knock on the dustproof net 12. The dustproof net 12 vibrates and shakes off the flying insects adhering to the dustproof net 12, thereby reducing the frequency of workers' maintenance of the dustproof net 12.

[0037] The sealing device 4 includes a circular plate 41, two trapezoidal plates 42, a circular rubber plate 43 and a resisting rod 44. The circular plate 41 is slidably installed inside the power distribution cabinet body 1. A spring sheet is arranged between the circular plate 41 and the inner wall of the power distribution cabinet body 1. The two trapezoidal plates 42 are respectively fixed on the left and right sides of the back of the circular plate 41. The circular rubber plate 43 is fixed on the front of the circular plate 41. The resisting rod 44 is fixed on the front of the Z-shaped tube 31. The inclined surface of the trapezoidal plate 42 is located on the motion track of the resisting rod 44. The Z-shaped tube 31 drives the resistance rod 44 to move downward, and the resistance rod 44 pushes the trapezoidal plate 42 to drive the circular plate 41 to move, and the circular plate 41 drives the circular rubber plate 43 to fit closely against the door of the distribution cabinet body 1, so that the circular rubber plate 43 seals the gap between the distribution cabinet body 1 and the door of the distribution cabinet body 1, thereby avoiding the problem of rainwater overflowing into the interior of the distribution cabinet body 1 through the gap between the distribution cabinet body 1 and the door of the distribution cabinet body 1, thereby improving the waterproof performance of the distribution cabinet body 1.

[0038] When in use, when the water collecting box 22 pushes the Z-shaped tube 31 to move downward, the Z-shaped tube 31 pushes the U-shaped frame 33 to squeeze the spring plate 35, and the spring plate 35 bulges and deforms. The spring plate 35 pushes the U-shaped slide plate 54 to move in the direction of the insect repellent box 51, and the U-shaped slide plate 54 squeezes the elastic pressing piece 52. The elastic pressing piece 52 squeezes the insect repellent in the insect repellent box 51 and sprays it from the spray pipe 53. The insect repellent kills the flying insects at the dustproof net 12, thereby reducing the probability of the flying insects blocking the dustproof net 12; at the same time, when the U-shaped frame 33 moves, the U-shaped frame 33 squeezes the spring plate 35 to deform. When the spring plate 35 does not push the U When the U-shaped slide plate 54 is moved, the U-shaped slide plate 54 will be reset under the elastic force of the elastic pressing piece 52. When the U-shaped slide plate 54 moves, it will push the protrusion of the elastic protrusion plate 55 to drive the elastic protrusion plate 55 to move away from the U-shaped slide plate 54, and the elastic protrusion plate 55 will drive the arc rod 56 away from the dust-proof net 12. When the U-shaped slide plate 54 does not push the protrusion of the elastic protrusion plate 55, under the elastic force of the elastic protrusion plate 55, the elastic protrusion plate 55 will drive the arc rod 56 to knock the dust-proof net 12, and the dust-proof net 12 will vibrate and shake off the flying insects adhering to the dust-proof net 12, thereby reducing the frequency of workers' maintenance of the dust-proof net 12.

[0039] At the same time, when the water collecting box 22 pushes the Z-shaped tube 31 to move downward, the Z-shaped tube 31 drives the resistance rod 44 to move downward, and the resistance rod 44 pushes the inclined surface of the trapezoidal plate 42 to push the circular plate 41 to move toward the front direction of the distribution cabinet body 1, and the circular plate 41 drives the circular rubber plate 43 to lean against the cabinet door of the distribution cabinet body 1, and the circular plate 41 pushes the circular rubber plate 43 close to the cabinet door of the distribution cabinet body 1, so that the circular rubber plate 43 seals the gap between the distribution cabinet body 1 and the cabinet door of the distribution cabinet body 1, thereby avoiding the problem of rainwater overflowing into the interior of the distribution cabinet body 1 through the gap between the distribution cabinet body 1 and the cabinet door of the distribution cabinet body 1, thereby improving the waterproof performance of the distribution cabinet body 1.
