Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically a high- and low-voltage prefabricated prefabricated substation. Background Technology

[0002] Prefabricated high and low voltage box-type substations, or simply box-type substations, are factory-prefabricated integrated power distribution equipment. They integrate high-voltage switches, distribution transformers, low-voltage power distribution, and auxiliary devices, with internal compartments divided into independent functional chambers. This equipment can perform high-voltage step-down, power distribution, protection, and metering functions. It features a compact structure, small footprint, convenient installation, and simple operation and maintenance. It also has waterproof, dustproof, and condensation-proof outdoor use capabilities, and is widely used in residential communities, industrial parks, municipal engineering projects, photovoltaic and wind power projects, and temporary construction sites. It is a mainstream power distribution facility in urban and rural power distribution networks. Internal fans draw in internal air, allowing external air to flow into the box through fish-scale-shaped perforations, achieving foundation cooling.

[0003] To ensure effective heat dissipation within the prefabricated substation, perforations resembling fish scales are typically installed on the outer wall of the enclosure door. Driven by a fan, outside air continuously enters the enclosure through these perforations. In actual use, due to the small spacing between the perforations, rainwater splashing when it falls on the perforation shields can easily reach the air inlets and be drawn into the substation with the airflow. This rapid influx of rainwater can lead to excessively high humidity inside the equipment, affecting its safe operation. To address these shortcomings, this invention proposes an improvement. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a high- and low-voltage prefabricated box-type substation, including a base, a substation shell fixedly connected to the top of the base, a door rotatably connected to the side wall of the substation shell, and a plurality of fish-scale holes opened on the side wall of the door, and further including: The limiting mechanism is fixedly installed on the side wall of the cabinet door. The limiting mechanism includes a fixing plate fixedly connected to the side wall of the cabinet door, and several arc-shaped plates are fixedly connected to the side wall of the fixing plate. The fixing mechanism is located on the side wall of the arc-shaped plate one. The fixing mechanism includes several intercepting rods fixedly connected to the side wall of the arc-shaped plate one. The bottom of the arc-shaped plate one is fixedly connected to the fixing plate two.

[0005] Auxiliary mechanisms are fixedly installed on the side wall of the substation enclosure; In this process, after the auxiliary mechanism extracts the air from inside the substation casing, the outside air will enter the substation casing through the fish-scale holes and complete the cooling operation inside the substation casing.

[0006] Preferably, the limiting mechanism includes: The fixing component is fixedly installed on the side wall of the fixing plate one; Through-hole assembly, the through-hole assembly is opened on the side wall of the fixing plate one; The fixing plate is fixedly installed on the side wall of the door by a fixing component.

[0007] Preferably, the fixing mechanism includes: Interception components are arranged at both ends of the arc-shaped plate. The guide components are fixedly installed on both sides of the fixed plate two; When external rainwater accumulates in the gap between the arc-shaped plate one and the fish-scale holes, the accumulated rainwater will be discharged outward through the interception component and the arc-shaped plate two.

[0008] Preferably, the auxiliary mechanism includes: The circulation component is fixedly installed on the side wall of the substation casing; The circulation component continuously draws air from inside the substation casing and discharges it to the outside.

[0009] Preferably, the fixing component includes a plurality of bolts fixedly connected to one side wall of the fixing plate; When the fixing plate is fixed to the side wall of the box door with bolts, the through hole assembly should be fitted onto the outside of the fish scale hole.

[0010] Preferably, the through-hole assembly includes a plurality of through holes formed on one side wall of the fixing plate; The number of through holes, fish scale holes and arc-shaped plates are equal.

[0011] Preferably, the interception component includes flow grooves formed on both sides of the arc-shaped plate; Rainwater located between the curved plate and the fish-scale holes will flow outward through the flow channel.

[0012] Preferably, the guide component includes an arc-shaped plate two fixedly connected to both sides of the fixed plate two; The edge of the second curved plate is in close contact with the edge of the first fixed plate, and a rubber pad is fixed to the top of the second fixed plate. When the second fixed plate is in contact with the fish scale hole, the rubber pad is deformed under pressure to achieve a seal.

[0013] Preferably, the circulation component includes a fan fixedly connected to the side wall of the substation casing, and an operation panel is fixedly connected to the side wall of the fan; The system includes a fan that draws air from inside the substation casing, while outside air enters the substation casing through fish-scale-shaped holes. Additionally, there are four interception bars.

[0014] The present invention has the following beneficial effects: (1) In view of the problem that raindrops splashing and being collected by the fish scale holes, the present invention provides an arc-shaped plate and an intercepting rod inside the device. When raindrops fall towards the fish scale holes, the rainwater will first penetrate the gap between the intercepting rods and enter the gap between the arc-shaped plate and the fish scale holes. At this time, the raindrops will be divided into multiple water droplets by the intercepting rods and then hit the outer wall of the fish scale holes. Since the intercepting rods are triangular with a smaller top and a larger bottom, most of the splashing raindrops will spread outward and be intercepted by the bottom plane of the arc-shaped plate. Through the above design, the total amount of rainwater entering the substation shell in a certain period of time is reduced.

[0015] (2) The present invention utilizes the above-mentioned design of raindrops preferentially penetrating the gap of the interception bar. The interception bar is designed as a triangle with a smaller top and a larger bottom. When rainwater falls obliquely due to external environmental factors, the raindrops will hit the interception bar in an oblique manner. The rainwater splashed against each other will cover the outer wall of the arc plate, forming a "buffer zone". When subsequent raindrops fall downward, the subsequent raindrops will mix with the splashed water droplets. At this time, the lateral potential energy of the splashed water droplets will be absorbed by the subsequent raindrops, and the impact force and splash range of the raindrops are greatly reduced.

[0016] (3) The present invention utilizes the above-mentioned design of rainwater accumulating in the gap between the fish scale hole and the arc plate to set up an interception component and a guiding component inside the equipment. The rainwater accumulated in the gap will be discharged outward through the flow channel, and will come into contact with the rainwater outside the fixed plate along the outer wall of the arc plate and finally drip down along the outer wall of the fixed plate. At the same time, the rubber pad improves the airtightness between the fish scale hole and the fixed plate. Through the above design, rainwater is prevented from accumulating at position U through the gap between the fish scale hole and the fixed plate, which would cause the rainwater at position U to flow upward along the inner wall of the fish scale hole when the fish scale hole is drawing air, resulting in the problem of increased humidity inside the substation shell.

[0017] (4) The present invention utilizes the design of the above-mentioned arc plate two to guide the rainwater inside the gap to flow outward, so that the accumulated rainwater flows out downward through the fixed plate one, avoiding the rainwater inside the gap from dripping down from the outer wall of the arc plate one in the form of water droplets, and under the action of external wind force, the falling water droplets come into contact with the arc plate one below again, reducing the load on the overall waterproof structure.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figures 1-6 This invention relates to a high- and low-voltage prefabricated box-type substation, comprising a base 13, a substation housing 14 fixedly connected to the top of the base 13, a door 15 rotatably connected to the side wall of the substation housing 14, and a plurality of fish-scale holes 16 formed on the side wall of the door 15, and further comprising: The limiting mechanism 1 is fixedly installed on the side wall of the door 15. The limiting mechanism 1 includes a fixing plate 111 fixedly connected to the side wall of the door 15. Several arc-shaped plates 122 are fixedly connected to the side wall of the fixing plate 111. Fixing mechanism 2 is located on the side wall of the arc plate 122. Fixing mechanism 2 includes several intercepting rods 211 fixedly connected to the side wall of the arc plate 122. Fixing plate 221 is fixedly connected to the bottom of the arc plate 122.

[0023] Auxiliary mechanism 3 is fixedly installed on the side wall of the substation casing 14; In this process, after the auxiliary mechanism 3 extracts the air from inside the substation housing 14, the outside air will enter the substation housing 14 through the fish-scale holes 16 and complete the cooling operation inside the substation housing 14.

[0024] Restricted agency 1 includes: Fixing component 11 is fixedly disposed on the side wall of fixing plate 111; Through-hole assembly 12, which is formed on the side wall of fixing plate 111; To address the issue of raindrops splashing and being collected by the fish-scale holes 16, an arc-shaped plate 122 and an intercepting rod 211 are installed inside the equipment. When raindrops fall towards the fish-scale holes 16, the rainwater will preferentially penetrate the gap between the intercepting rods 211 and enter the gap between the arc-shaped plate 122 and the fish-scale holes 16. At this time, the raindrops will be divided into multiple water droplets by the intercepting rods 211 and then hit the outer wall of the fish-scale holes 16. Since the intercepting rods 211 are triangular with a smaller top and a larger bottom, most of the splashing raindrops will spread outward and be intercepted by the bottom plane of the arc-shaped plate 122. Through the above design, the total amount of rainwater entering the substation casing 14 within a certain period of time is reduced.

[0025] Fixed mechanism 2 includes: Interception component 21 is arranged at both ends of the arc-shaped plate 122; Guide component 22 is fixedly mounted on both sides of the fixing plate 221; When external rainwater accumulates in the gap between the arc-shaped plate 122 and the fish-scale hole 16, the accumulated rainwater will be discharged outward through the interception component 21 and the arc-shaped plate 222.

[0026] Auxiliary mechanism 3 includes: The flow component 31 is fixedly installed on the side wall of the substation casing 14; The circulation component 31 continuously draws air from inside the substation casing 14 and discharges it to the outside.

[0027] Example 2, please refer to Figures 2-8 The present invention is a high and low voltage prefabricated box-type substation. Based on the first embodiment, the fixing component 11 includes a number of bolts 112 that are fixedly connected to the side wall of the fixing plate 111. When the fixing plate 111 is fixed to the side wall of the box door 15 by bolts 112, the through hole assembly 12 should be fitted onto the outside of the fish scale hole 16. The arc plate 122 will completely cover the outer wall of the fish scale hole 16, and there will be a gap between the fish scale hole 16 and the arc plate 122. The side wall of the fixing plate 221 is in close contact with the end of the fish scale hole 16. The rubber pad will be deformed under pressure, so that rainwater cannot flow down through the gap between the fixing plate 221 and the fish scale hole 16.

[0028] Through-hole assembly 12 includes a plurality of through holes 121 formed in the side wall of fixed plate 111; Utilizing the design that prioritizes raindrop penetration through the gaps in the interceptor bar 211, the interceptor bar 211 is designed as a triangle, smaller at the top and larger at the bottom. When rainwater drips obliquely due to external environmental factors, the raindrops will impact the interceptor bar 211 at an angle. Figure 9 As shown, when raindrops fall downwards along path M, the rainwater will simultaneously come into contact with positions H and G on the interceptor bar. At this time, some of the rainwater that comes into contact with position H will splash towards position G, while some of the rainwater that comes into contact with position G will splash towards position H. The rainwater that splashes against each other will cover the outer wall of the arc plate 122, forming a "buffer zone".

[0029] The interception component 21 includes flow channels 212 formed on both sides of the arc-shaped plate 122; As subsequent raindrops fall downwards, they mix with the splashing water droplets. At this point, the lateral potential energy of the splashing water droplets is absorbed by the subsequent raindrops, significantly reducing the impact force and splash range of the raindrops.

[0030] The guide component 22 includes an arc-shaped plate 222 fixedly connected to both sides of the fixed plate 221; Utilizing the design that allows rainwater to accumulate in the gap between the fish-scale holes 16 and the arc-shaped plate 122, an interception component 21 and a guiding component 22 are installed inside the device. Rainwater accumulated in the gap will be discharged outwards through the flow channel 212, contacting the rainwater on the outside of the fixed plate 111 along the outer wall of the arc-shaped plate 222, and finally dripping down the outer wall of the fixed plate 111. Simultaneously, the rubber pad improves the airtightness between the fish-scale holes 16 and the fixed plate 221. Through this design, rainwater is prevented from accumulating in the gap between the fish-scale holes 16 and the fixed plate 221. Figure 8 The position of U causes rainwater at position U to flow upward along the inner wall of the fish scale hole 16 when air is drawn in, resulting in increased humidity inside the substation casing 14.

[0031] The circulation component 31 includes a fan 311 fixedly connected to the side wall of the substation housing 14, an operation panel 312 fixedly connected to the side wall of the fan 311, and four interception bars 211.

[0032] By utilizing the design of the arc-shaped plate 222 to guide the rainwater inside the gap to flow outward, the accumulated rainwater flows downward through the fixed plate 111, preventing the rainwater inside the gap from dripping down from the outer wall of the arc-shaped plate 122 in the form of water droplets. Furthermore, under the action of external wind, the falling water droplets come into contact with the arc-shaped plate 122 below again, reducing the load on the overall waterproof structure.

[0033] One specific application of this embodiment is as follows: Before use, the fixing plate 111 needs to be fixed to the side wall of the door 15 using bolts 112. Since the number of through holes 121 and fish scale holes 16 is equal, during installation, it is necessary to ensure that each fish scale hole 16 passes through the through hole 121, presenting the following appearance. Figure 7 In state P, the arc-shaped plate 122 will completely cover the outer wall of the fish-scale hole 16, and there will be a gap between the fish-scale hole 16 and the arc-shaped plate 122. The side wall of the fixing plate 221 will be in close contact with the end of the fish-scale hole 16. The rubber pad will be deformed under pressure, so that rainwater cannot flow down through the gap between the fixing plate 221 and the fish-scale hole 16.

[0034] To address the issue of raindrops splashing and being collected by the fish-scale holes 16, an arc-shaped plate 122 and an intercepting rod 211 are installed inside the equipment. When raindrops fall towards the fish-scale holes 16, the rainwater will preferentially penetrate the gap between the intercepting rods 211 and enter the gap between the arc-shaped plate 122 and the fish-scale holes 16. At this time, the raindrops will be divided into multiple water droplets by the intercepting rods 211 and then hit the outer wall of the fish-scale holes 16. Since the intercepting rods 211 are triangular with a smaller top and a larger bottom, most of the splashing raindrops will spread outward and be intercepted by the bottom plane of the arc-shaped plate 122. Through the above design, the total amount of rainwater entering the substation casing 14 within a certain period of time is reduced.

[0035] Utilizing the design that prioritizes raindrop penetration through the gaps in the interceptor bar 211, the interceptor bar 211 is designed as a triangle, smaller at the top and larger at the bottom. When rainwater drips obliquely due to external environmental factors, the raindrops will impact the interceptor bar 211 at an angle. Figure 9 As shown, when a raindrop falls downward along path M, the rainwater will simultaneously contact positions H and G on the interceptor bar 211. At this time, some of the rainwater that contacts position H will splash towards position G, and some of the rainwater that contacts position G will splash towards position H. The splashed rainwater will cover the outer wall of the arc plate 122, forming a "buffer zone". When subsequent raindrops fall downward, they will mix with the splashed water droplets. At this time, the lateral potential energy of the splashed water droplets will be absorbed by the subsequent raindrops, and the impact force and splash range of the raindrops will be greatly reduced.

[0036] Utilizing the design that allows rainwater to accumulate in the gap between the fish-scale holes 16 and the arc-shaped plate 122, an interception component 21 and a guiding component 22 are installed inside the device. Rainwater accumulated in the gap will be discharged outwards through the flow channel 212, contacting the rainwater on the outside of the fixed plate 111 along the outer wall of the arc-shaped plate 222, and finally dripping down the outer wall of the fixed plate 111. Simultaneously, the rubber pad improves the airtightness between the fish-scale holes 16 and the fixed plate 221. Through this design, rainwater is prevented from accumulating in the gap between the fish-scale holes 16 and the fixed plate 221. Figure 8 The position of U causes rainwater at position U to flow upward along the inner wall of the fish scale hole 16 when air is drawn in, resulting in increased humidity inside the substation casing 14.

[0037] By utilizing the design of the arc-shaped plate 222 to guide the rainwater inside the gap to flow outward, the accumulated rainwater flows downward through the fixed plate 111, preventing the rainwater inside the gap from dripping down from the outer wall of the arc-shaped plate 122 in the form of water droplets. Furthermore, under the action of external wind, the falling water droplets come into contact with the arc-shaped plate 122 below again, reducing the load on the overall waterproof structure.
