AI Technical Summary
Although the existing heat dissipation mechanisms of substations can prevent rainwater from entering, water droplets splashed on the ground may still move upwards and enter the interior of the substation, resulting in poor waterproofing.
It adopts a combination structure of multiple irregular plates, baffles, and shielding plates. Gravity is used to make water droplets drip along the irregular plates to the outside. At the same time, the rotation of gears is stabilized by the cooperation of sliding plates, sliders, and push blocks, which precisely controls the rotation of irregular plates to form a waterproof structure and maintain heat dissipation function.
It effectively prevents water droplets from entering the substation while maintaining air exchange between the inside and outside, achieving good waterproofing and heat dissipation effects.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of substation technology, and in particular to a waterproof structure for a substation. Background Technology
[0002] Substations are an important component of the power system. Their main function is to receive high-voltage electricity from power plants or other power grids, convert it into low-voltage electricity suitable for transmission or use through transformers, and then distribute it. Airflow in substations can prevent the internal temperature from rising. However, airflow necessitates a heat dissipation mechanism. While existing substation heat dissipation mechanisms can prevent rainwater from entering by being tilted downwards, raindrops splashing on the ground also tend to move upwards, potentially causing water droplets to enter the substation. Therefore, a waterproof substation structure is needed to solve this problem. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies. Substations are an important component of power systems, primarily responsible for receiving high-voltage electricity from power plants or other power grids, converting it into low-voltage electricity suitable for transmission or use via transformers, and distributing it. Airflow within substations helps prevent internal temperature rise, but this airflow necessitates cooling mechanisms. While existing substation cooling mechanisms can prevent rainwater ingress by tilting downwards, raindrops splashing on the ground also tend to move upwards, potentially allowing water to enter the substation. Therefore, this invention provides a waterproof structure for substations.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof structure for a substation, comprising a housing, a fixing hole on one side of the housing, a heat dissipation mechanism embedded in the inner wall of the fixing hole, the heat dissipation mechanism comprising a support plate, a fixing plate and a waterproof structure arranged opposite to each other, the waterproof structure comprising a shielding plate, multiple sets of irregular plates and baffles arranged from top to bottom between the support plate and the fixing plate, multiple rotating grooves on the side of the fixing plate opposite to the support plate, a rotating rod rotatably connected to the inner wall of the rotating groove, and an irregular plate fixedly connected to one end of the rotating rod.
[0005] In a preferred embodiment, the outer surfaces of the support plate and the fixing plate are slidably connected to the outer surface of the irregular plate, the outer surface of the fixing plate is fixedly connected to the inner wall of the fixing hole, and the outer surface of the support plate is fixedly connected to the inner wall of the fixing hole.
[0006] In a preferred embodiment, a sliding groove is provided on one side of the support plate, and a shaft groove is provided on the inner wall of the sliding groove, with a shaft rod rotatably connected to the inner wall of the shaft groove.
[0007] In a preferred embodiment, one end of the shaft is fixedly connected to one side of the irregular plate, and the other end of the shaft is fixedly connected to a gear.
[0008] In a preferred embodiment, a slide plate is slidably connected to the inner wall of the slide groove, a slider is fixedly connected to one side of the slide plate, a push block is fixedly connected to one side of the slider, and a toothed rack is fixedly connected to the other side of the slide plate, with the toothed rack meshing with a gear.
[0009] In a preferred embodiment, two limiting plates are fixedly connected to the inner wall of the slide groove, and the outer surface of the slider is slidably connected to the inner wall of the slide groove.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: by using multiple irregular plates in combination, the curved shape of the irregular plates can shield the splashed water droplets. At the same time, due to the curved surface, when water droplets splash onto the surface of the irregular plates, they will drip down the irregular plates to the outside of the box due to gravity, thereby preventing water droplets from entering the inside of the box. By using the sliding plate, slider, push block and slide groove in cooperation, the structure of the gear rack can be made more stable, increasing the structural stability of the equipment. At the same time, the movement trajectory of the slider is limited by the limiting plate, thereby enabling more precise control of the gear rotation degree, and the push block achieves the effect of facilitating the control of the movement of the gear rack.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example
[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a waterproof structure for a substation, including a housing 1, a fixing hole 3 on one side of the housing 1, a heat dissipation mechanism 2 on the inner wall of the fixing hole 3, the heat dissipation mechanism 2 including a support plate 21 and a fixing plate 22, a plurality of rotating grooves on one side of the fixing plate 22, a rotating rod 23 rotatably connected to the inner wall of the rotating grooves, a special-shaped plate 24 fixedly connected to one end of the rotating rod 23, the outer surfaces of the support plate 21 and the fixing plate 22 being slidably connected to the outer surface of the special-shaped plate 24, a baffle 25 adapted to the special-shaped plate 24 being fixedly connected to one side of the fixing plate 22, a shielding plate 26 being fixedly connected to one side of the fixing plate 22, the outer surface of the fixing plate 22 being fixedly connected to the inner wall of the fixing hole 3, the outer surface of the support plate 21 being fixedly connected to the inner wall of the fixing hole 3, one side of the baffle 25 being fixedly connected to the inner wall of the fixing hole 3, and the outer surface of the shielding plate 26 being fixedly connected to the inner wall of the fixing hole 3;
[0022] One side of the baffle 25 is fixedly connected to one side of the support plate 21, and one side of the shielding plate 26 is fixedly connected to one side of the support plate 21.
[0023] Through the above embodiments, multiple irregular plates 24 are used in combination. The curved shape of the irregular plates 24 can shield the splashed water droplets. At the same time, due to the curved shape, when water droplets splash onto the surface of the irregular plates 24, they will drip down the irregular plates 24 to the outside of the box 1 by gravity, thereby preventing water droplets from entering the inside of the box 1.
[0024] Furthermore, the rotating rod 23 and the shaft 28 enable the irregular plate 24 to rotate. After multiple irregular plates 24 rotate, they will form a contact state, which can further prevent water droplets from entering the interior of the box 1. At the same time, the shield 26 set at the top can prevent rainwater from entering, and the baffle 25 set at the bottom will contact the bottom irregular plate 24, so the possibility of water droplets entering from this point is extremely small. Thus, multiple irregular plates 24, baffle 25 and shield 26 can form a waterproof structure to prevent water droplets and rainwater from entering. At the same time, it can also serve as a heat dissipation structure to allow the air inside the box 1 to exchange with the outside air to achieve a heat dissipation effect.
[0025] A sliding groove 27 is provided on one side of the support plate 21, and a shaft groove is provided on the inner wall of the sliding groove 27. A shaft rod 28 is rotatably connected to the inner wall of the shaft groove.
[0026] One end of the shaft 28 is fixedly connected to one side of the profile plate 24, and the other end of the shaft 28 is fixedly connected to a gear 29;
[0027] The inner wall of the slide 27 is slidably connected to a slide plate 210. A slider 212 is fixedly connected to one side of the slide plate 210. A push block 213 is fixedly connected to one side of the slider 212. A toothed rack 214 is fixedly connected to the other side of the slide plate 210. The toothed rack 214 is meshed with the gear 29.
[0028] Two limiting plates 211 are fixedly connected to the inner wall of the slide groove 27, and the outer surface of the slider 212 is slidably connected to the inner wall of the slide groove 27.
[0029] Through the above embodiments, by having the slide plate 210, slider 212, and push block 213 cooperate with the slide groove 27, the structure of the gear rack 214 can be made more stable, increasing the structural stability of the equipment. At the same time, the movement trajectory of the slider 212 is limited by the limiting plate 211, thereby enabling more precise control of the rotation degree of the gear 29, and the push block 213 achieves the effect of facilitating the control of the movement of the gear rack 214.
[0030] Working principle:
[0031] like Figures 1-5As shown, in use, the push block 213 drives the slider 212 to move, the slider 212 moves the slide plate 210, the slide plate 210 moves the gear 214, the gear 214 moves the gear 29, the gear 29 moves the shaft 28, and the shaft 28 moves the irregular plate 24. The rotating rod 23 and the shaft 28 can make the irregular plate 24 rotate. After multiple irregular plates 24 rotate, they will form a contact state, which can further prevent water droplets from entering the interior of the box 1. At the same time, the shield 26 set at the top can prevent rainwater from entering, and the baffle 25 set at the bottom will contact the bottom irregular plate 24, so the possibility of water droplets entering from here is extremely small. Thus, multiple irregular plates 24, baffle 25 and shield 26 can form a waterproof structure to prevent water droplets and rainwater from entering. At the same time, it can also serve as a heat dissipation structure to exchange the air inside the box 1 with the outside air to achieve a heat dissipation effect.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
