Prepackaged box-type substation with rainproof flow guide structure

Abstract

This utility model belongs to the field of power equipment protection technology, and particularly relates to a prefabricated box-type substation with a rainproof and flow-guiding structure. It includes a transformer box, protective doors, and a flow-guiding top. Two protective doors are rotatably mounted on the front of the transformer box, arranged side-by-side and in contact with each other. A flow-guiding top is installed on the top of the transformer box. This utility model, by incorporating a flow-guiding top, water tank, flow-guiding hopper, filter plate, and connecting pipes, not only effectively collects rainwater, preventing it from directly impacting the top of the transformer box and flowing along the side walls into the interior, but also absorbs the heat emitted by the transformer box as the rainwater flows through the connecting pipes, achieving physical cooling of the transformer box. Simultaneously, through a drain pipe, solenoid valve, water level detector, detection probe, and controller, the rainwater collected in the water tank is promptly discharged to prevent water accumulation. The overall structure combines rainproof and flow-guiding functions, heat dissipation, and intelligent drainage, significantly improving the operational reliability of the box-type substation.

Description

Technical Field

[0001] This utility model belongs to the field of power equipment protection technology, and in particular relates to a prefabricated box-type substation with a rainproof and flow-guiding structure. Background Technology

[0002] Prefabricated box-type substations are complete sets of power distribution equipment that integrate high-voltage switchgear, transformers, and low-voltage power distribution devices. They have advantages such as compact structure, convenient installation, and reliable operation, and are widely used in outdoor power distribution scenarios such as urban power distribution networks, industrial parks, residential communities, and temporary power supply.

[0003] In open-air operation, prefabricated substations are often directly exposed to rainy weather. Rainwater directly impacts the top of the enclosure and flows along the side walls. It can easily seep into the interior through the enclosure joints, door gaps, cable entry points, etc., causing electrical equipment to become damp and its insulation performance to deteriorate, which can lead to short circuits, corrosion, or even operational failures, seriously affecting the reliability of power supply.

[0004] Therefore, there is a particular need for a prefabricated box-type substation with a rainproof and flow-guiding structure to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing prefabricated substations that are prone to dampness, short circuits or corrosion due to rainwater infiltration during rainy weather, which threatens the reliability of power supply, this utility model provides a prefabricated prefabricated substation with a rainproof and flow-guiding structure.

[0006] This utility model is achieved through the following technical means: a prefabricated box-type substation with a rainproof and flow-guiding structure, including a transformer box, protective doors, a flow-guiding top, a water tank, flow-guiding hoppers, a filter plate, connecting pipes, a drain pipe, a solenoid valve, a support plate, a water level detector, a detection probe, and a controller. Two protective doors arranged side-by-side are rotatably mounted on the front of the transformer box, and the two protective doors are in contact with each other. A flow-guiding top is installed on the top of the transformer box, completely obscuring the transformer box from a top-down view. A water tank is installed at the bottom of the transformer box. Two flow-guiding hoppers arranged left and right are fixedly connected to the lower part of the flow-guiding top, and the bottom surface of the flow-guiding hoppers is flush with the transformer box. The top surface remains in contact with the top of each guide hopper, and a filter plate is placed on top of each guide hopper. The filter plate is located inside the guide hopper top. Two connecting pipes arranged front and back are connected to the bottom of each guide hopper. The end of the connecting pipe away from the guide hopper top extends into the water tank. A drain pipe is connected to the lower rear of the water tank. A solenoid valve is installed on the drain pipe. Two support plates arranged side by side are installed on one side of the top of the water tank. A water level detector is installed on the left support plate. The detection probe connected to the lower part of the water level detector passes through the left support plate and extends into the water tank. A controller is installed on the right support plate. The solenoid valve and the water level detector are both electrically connected to the controller.

[0007] As a preferred technical solution of this utility model, it also includes hanging rings, with two symmetrically arranged hanging rings fixedly attached to the top of the flow guide.

[0008] As a preferred technical solution of this utility model, it also includes a handle, with a handle installed on both sides of the top of each filter plate.

[0009] As a preferred technical solution of this utility model, it also includes a protective shell, with protective shells installed on both sides of the transformer box, and the protective shells covering the two connecting pipes on the corresponding side.

[0010] As a preferred technical solution of this utility model, the connecting pipe adopts a serpentine bending arrangement to form a tortuous flow channel.

[0011] As a preferred technical solution of this utility model, the bottom of the detection probe is close to the bottom of the water tank.

[0012] Beneficial effects: This utility model, by setting up a guide top, water tank, guide bucket, filter plate and connecting pipe, can not only effectively collect rainwater and prevent rainwater from directly impacting the top of the transformer box and flowing along the side wall into the interior, but also absorb the heat emitted by the transformer box by the rainwater as it flows through the connecting pipe, thus achieving physical cooling of the transformer box. At the same time, through the drain pipe, solenoid valve, water level detector, detection probe and controller, the rainwater collected in the water tank is discharged in time to prevent water accumulation. The overall structure takes into account rainproof and guide functions, heat dissipation and intelligent drainage functions, significantly improving the operational reliability of the box-type substation.

[0020] Example: A prefabricated box-type substation with a rainproof and flow-guiding structure, such as... Figures 1-6 As shown, the system includes a transformer box 1, a protective door 2, a flow guide top 3, a hanging ring 4, a water tank 5, a flow guide hopper 6, a filter plate 7, a handle 8, a connecting pipe 9, a protective shell 10, a drain pipe 11, a solenoid valve 111, a support plate 12, a water level detector 13, a detection probe 131, and a controller 14. Two protective doors 2 are rotatably mounted on the front of the transformer box 1, arranged side-by-side and in contact with each other. A flow guide top 3 is bolted to the top of the transformer box 1, completely obscuring the transformer box 1 from a top-down view, ensuring that rainwater is absorbed by the flow guide top 3 during rainfall. The top of the guide tube 3 is fixedly connected to two symmetrically arranged hanging rings 4 for easy hoisting of the transformer box 1. A water tank 5 is bolted to the bottom of the transformer box 1. Two guide buckets 6 are fixedly connected to the lower part of the guide tube 3, arranged horizontally. The bottom surface of the guide buckets 6 is in contact with the top surface of the transformer box 1. A filter plate 7 is placed on top of each guide bucket 6, located inside the guide tube 3. Each filter plate 7 has handles 8 bolted to its top left and right sides for easy removal and cleaning. Two connecting pipes 9 are connected to the lower part of each guide bucket 6, arranged front and rear, with the connecting pipes 9 away from the guide tube. The lower end of the top 3 extends into the interior of the water tank 5. The connecting pipe 9 is arranged in a serpentine bend, forming a tortuous flow channel. When rainwater flows through the connecting pipe 9, the flow path is effectively extended, increasing the heat exchange time with the outer wall of the transformer box 1. Protective shells 10 are bolted to both sides of the transformer box 1, covering the two connecting pipes 9 on the corresponding side to prevent the connecting pipes 9 from being exposed and damaged. A drain pipe 11 is connected to the lower rear part of the water tank 5. A solenoid valve 111 is installed on the drain pipe 11. Two parallel valves are bolted to the rear top of the water tank 5. The support plate 12 is arranged in rows. A water level detector 13 is fixed to the left support plate 12 by bolts. The detection probe 131 connected to the lower part of the water level detector 13 passes through the left support plate 12 and extends into the water tank 5. The bottom end of the detection probe 131 is close to the bottom of the water tank 5 to ensure accurate detection of the low water level in the water tank 5. A controller 14 is fixed to the right support plate 12 by bolts. The solenoid valve 111 and the water level detector 13 are both electrically connected to the controller 14. The controller 14 is a programmable logic controller, model Huichuan Easy 521-24T4DT.

[0021] During rainfall, rainwater is collected by the guide top 3 and flows into the guide bucket 6. After impurities are filtered by the filter plate 7, it flows into the water tank 5 through the connecting pipe 9. During the flow of rainwater through the connecting pipe 9, it exchanges heat with the outer wall of the transformer box 1, achieving physical cooling of the transformer box 1. The rainwater flowing into the water tank 5 causes the water level in the water tank 5 to rise. The water level detector 13 monitors the water level in real time through the detection probe 131. When the water level rises to the point of submerging the bottom of the detection probe 131, the water level detector 13 sends a signal to the controller 14. The controller 14 controls the solenoid valve 111 to open the drain pipe 11 and discharge the rainwater in the water tank 5. After the rain stops, the water level in the water tank 5 gradually drops. When the detection probe 131 can no longer detect the water level, the controller 14 controls the solenoid valve 111 to close the drain pipe 11 and stop the drainage.
