Description

Technical Field

[0001] This application relates to the field of substations, and particularly to a box-type substation. Background Art

[0002] With the rapid development of social economy and the transformation and upgrading of urban and rural power grids, the disadvantages of traditional substations in terms of land occupation, construction, and maintenance costs have gradually emerged. For this reason, box-type substations, as a new type of compact power supply and distribution device, have emerged as the times require. A box-type substation is a complete set of power distribution device that organically combines functions such as high-voltage power reception, transformer step-down, and low-voltage power distribution, and has characteristics such as a compact structure and small floor area. It arranges high-voltage switchgear, distribution transformers, and low-voltage power distribution devices in a certain wiring scheme into one body, and installs them in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, and movable steel structure box body, with mechatronics and fully enclosed operation.

[0003] Although box-type substations have obvious advantages in terms of portability and economy, there are still certain limitations in heat dissipation performance and electrical safety, and electronic components are prone to shorten their service life due to high temperature. Summary of the Invention

[0004] In order to extend the service life of the box-type substation, this application provides a box-type substation.

[0005] A box-type substation provided by this application adopts the following technical solutions: A box-type substation includes a box body and a water pump. The box body is provided with a receiving cavity and a heat dissipation channel. The heat dissipation channel is arranged on the outer periphery of the receiving cavity. The upper end of the box body is provided with a water storage tank. The bottom of the water storage tank is provided with a water inlet. The outer wall of the box body is provided with a water outlet and a return port. The water inlet and the water outlet are respectively communicated with both ends of the heat dissipation channel. The return port is communicated with the water storage tank. The pump body of the water pump is fixedly connected to the outer wall of the box body. The water inlet end of the water pump is communicated with the water outlet through a water inlet pipe. The water outlet end of the water pump is communicated with the return port through a water outlet pipe.

[0006] By adopting the above technical solutions, the water storage tank is used for storing water, and the water pump drives the water to circulate in the water storage tank and the heat dissipation channel, which is convenient for dissipating heat from the box body and extending the service life of the box-type substation.

[0007] Preferably, it further includes an airbag and a switch. The outer wall of the box body is provided with a through port. The through port is communicated with the receiving cavity. The airbag is fixedly connected to the inner wall of the through port. The mouth of the airbag faces the receiving cavity. The switch is fixedly connected to the outer wall of the box body. The switch is used for the airbag to abut against, and the switch is electrically connected to the water pump.

[0008] By adopting the above technical solution, when the temperature of the box body rises, the gas in the accommodating cavity expands and contracts due to heat, the airbag expands and abuts against the switch, the water pump starts to change the water in the heat dissipation channel, reducing the temperature of the box body and prolonging the service life of the box-type substation.

[0009] Preferably, it further includes a sliding plate and a control column. The sliding plate is arranged below the return port. The sliding plate is slidably connected to the wall of the water storage tank. The sliding direction of the sliding plate is vertical. The sliding plate is provided with a control port. The control column passes through the control port. The control column includes a plugging column and a supporting column. The supporting column is fixedly connected to the bottom of the water storage tank. The plugging column is coaxially and fixedly connected to the upper end of the supporting column. The diameter of the plugging column is equal to the diameter of the control port. The diameter of the supporting column decreases as it approaches the bottom of the water storage tank.

[0010] By adopting the above technical solution, the water discharged from the heat dissipation channel flows back above the sliding plate for heat dissipation. The water below the sliding plate replenishes the water in the heat dissipation channel, improving the heat dissipation efficiency. The sliding plate slides downward, causing the water above the sliding plate to flow to below the sliding plate, realizing water circulation and improving the heat dissipation efficiency.

[0011] Preferably, it further includes a first spring. One end of the first spring is fixedly connected to the bottom of the water storage tank, and the other end of the first spring is fixedly connected to the sliding plate.

[0012] By adopting the above technical solution, when the water volume above the sliding plate increases, the first spring contracts, the sliding plate slides downward, and there is a gap between the inner wall of the control port and the supporting column. The water above the sliding plate automatically flows into the area below the sliding plate.

[0013] Preferably, it further includes a filter plate. The filter plate is arranged above the return port. The filter plate is provided with a filter port. The filter port vertically penetrates the filter plate. The filter plate is slidably connected to the wall of the water storage tank. The sliding direction of the filter plate is vertical.

[0014] By adopting the above technical solution, the filter plate reduces the probability of foreign impurities entering the water storage tank. The filter port facilitates the heat dissipation of the water in the water storage tank, improving the heat dissipation efficiency.

[0015] Preferably, it further includes a plugging plate. The plugging plate is slidably connected to the lower end of the filter plate. The plugging plate is used to block the filter port. The plugging plate is provided with a circulation port for communicating with the filter port.

[0016] By adopting the above technical solution, the sliding of the plugging plate is used to control the connection between the circulation port and the filter port, facilitating the control of the on-off of the filter port.

[0017] Preferably, a second spring is further included. A sliding groove is provided on the groove wall of the water storage tank. A sliding plate is fixedly connected to the outer wall of the filter plate. The sliding plate is slidably embedded in the sliding groove. One end of the second spring is fixedly connected to the upward groove wall of the sliding groove, and the other end of the second spring is fixedly connected to the sliding plate.

[0018] By adopting the above technical solution, when it rains outside, the rainwater fills the filter opening, increasing the overall weight of the filter plate and the blocking plate. The second spring is compressed, causing the filter plate to slide downward.

[0019] Preferably, a push block is further included. The push block is arranged below the filter plate. The push block is fixedly connected to the groove wall of the water storage tank. There are two push blocks, and the two push blocks are respectively arranged on both sides of the blocking plate. Both ends of the blocking plate facing the push block are fixedly connected with abutting blocks. The push blocks and the abutting blocks are arranged in one-to-one correspondence. An abutting surface is provided at one end of the push block facing the blocking plate. The two abutting surfaces are parallel to each other, and the abutting surface is used for the abutting block to abut.

[0020] By adopting the above technical solution, the abutting block abuts against the abutting surface. The up-and-down sliding of the filter plate causes the blocking plate to slide, realizing the opening and closing control of the filter opening. When it rains outside, the rainwater increases the weight of the filter plate. The second spring is compressed, and the filter plate slides downward. The blocking plate slides to open the filter opening, facilitating the replenishment of the water storage tank with rainwater at a lower temperature and improving the heat dissipation efficiency.

[0021] Preferably, a control board is further included. An overflow port is provided on the outer wall of the box body. The overflow port is arranged below the filter plate. The overflow port communicates with the water storage tank. One end of the control board is fixedly connected to the filter plate, and the other end of the control board is slidably connected to the groove wall of the water storage tank. The control board is used to control the opening and closing of the overflow port.

[0022] By adopting the above technical solution, when the filter plate slides downward, the filter opening and the overflow port are opened. The outside rainwater enters the water storage tank, and the water in the water storage tank is discharged from the box body, realizing water circulation and improving the heat dissipation efficiency.

[0023] Preferably, a rotating column, an impeller and a stirring rod are further included. The rotating column is arranged below the overflow port. The rotating column is rotatably connected to the box body around its own axis. One end of the rotating column is arranged in the water storage tank, and the other end of the rotating column is arranged outside the box body. The impeller is arranged outside the box body. The impeller is coaxially and fixedly connected to the rotating column. The stirring rod is arranged in the water storage tank. The stirring rod is fixedly connected to the outer wall of the rotating column.

[0024] By adopting the above technical solution, the water discharged from the overflow port causes the impeller to rotate. The rotation of the stirring rod makes the water in the water storage tank mix evenly, improving the heat dissipation efficiency.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The water tank is used to store water, and the water pump drives the water to circulate in the water tank and the heat dissipation channel, which is convenient for heat dissipation of the box body and prolongs the service life of the box-type substation; 2. When the temperature of the box rises, the gas in the accommodating cavity expands and contracts, the air bag expands and contacts the switch, and the water pump starts to replace water in the heat dissipation channel, thereby reducing the temperature of the box and extending the service life of the box-type substation; 3. When the filter plate slides downward, the filter port and overflow port open, the outside rainwater enters the water storage tank, and the water in the water storage tank is discharged from the box, realizing water circulation and improving heat dissipation efficiency.
