Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a prefabricated substation with good protection performance. Background Art

[0002] A prefabricated substation, also known as a box-type substation, organically combines functions such as transformer step-down and low-voltage power distribution, and is installed in a closed steel structure box. The prefabricated substation supplies power to industries and residents by transforming voltage. Generally, the prefabricated substation operates in a fully sealed and unmanned manner, and the equipment in the box is relatively compact. In order to facilitate the timely dissipation of heat generated during equipment operation, the prefabricated substation mainly relies on natural air cooling, and installs louvers on the box body to ensure ventilation and heat dissipation while being able to intercept foreign objects from the outside.

[0003] When there are many trees around the installation location of the prefabricated substation, the fallen leaves of the trees can enter the box along the gaps of the louvers when they flutter with the wind. Once a fire breaks out in the equipment, the fallen leaves in the box will increase the speed of fire spread, which is not conducive to fire fighting. Summary of the Invention

[0004] By providing a prefabricated substation with good protection performance in the embodiments of the present application, the problem in the prior art that when there are many trees around the installation location of the prefabricated substation, the fallen leaves of the trees can enter the box along the gaps of the louvers when they flutter with the wind, and once a fire breaks out in the equipment, the fallen leaves in the box will increase the speed of fire spread is solved.

[0006] The protection component includes a protection frame, a partition board, and an air supply pipe one;

[0007] The protection frame is a rectangular frame with a hollow interior and openings on both sides in the long side direction. The protection frame is fixed on the surface of the louver, and the protection frame is parallel to the louver;

[0010] The outlet end of the branch pipe is fixed with two air guide pipes, and the outlet ends of the air guide pipes extend into the gas soft bags;

[0011] When the branch pipe is inflated, the two gas soft bags in the ventilation cavity expand simultaneously until they collide with each other. When the branch pipe is evacuated, the two gas soft bags in the ventilation cavity shrink and return to their original positions.

[0012] Furthermore, there are multiple partitions, and the multiple partitions are evenly spaced and distributed in the protection frame, and the side surfaces of the partitions are in contact with the surface of the blinds;

[0014] Furthermore, a baffle is fixed on the protective frame, and an infrared sensor is fixed on one side of the baffle close to the ventilation cavity. The infrared sensor is electrically connected to the air pump of the air supply pipe 1 through a circuit.

[0015] Furthermore, the protection assembly also includes a collection tank;

[0016] The collecting tank is a rectangular plate with a hollow interior and an opening at the top, and is fixed to the bottom of the protection frame. The bottom of the protection frame has an opening, and the bottom opening of the protection frame coincides with the top opening of the collecting tank.

[0017] Furthermore, a metal plate is fixed to the side of the collecting tank via a connecting plate, a positioning plate is fixed to the side of the protective frame, and a sliding groove for use with the metal plate is provided at the bottom of the positioning plate.

[0021] Furthermore, a weight plate is fixed on each of the two gas soft bags in the ventilation cavity, and the weight plates can contact each other after the gas soft bags are expanded.

[0022] Furthermore, a control valve is fixed on each branch pipe.

[0023] Furthermore, each of the pressure plates is provided with ventilation holes.

[0024] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0025] Through the provided protection component, by inflating and deflating the air in the first air supply pipe, the gas soft bag can be expanded and contracted.

Specific implementation manners

[0041] To facilitate the understanding of the present invention, the present application will be described more comprehensively with reference to the relevant drawings; the preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0042] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] As Figures 1 to 10 shown, the present application provides a prefabricated substation with good protection performance, including a box body 100, on which a louver 110 for ventilation and heat dissipation is fixed, and further including a protection component 200, which is used to protect the louver 110 so that fallen leaves are not easily introduced into the box body 100 through the gaps of the louver 110;

[0045] The protection component 200 includes a protection frame 210, a partition board 212 and a first air supply pipe 220;

[0046] The protective frame 210 is a rectangular frame with a hollow interior and openings on both sides in the long side direction. The protective frame 210 is fixed on the surface of the louver 110 and is parallel to the louver 110. That is to say, the protective frame 210 does not block the louver 110 and does not affect the ventilation of the louver 110.

[0047] The partition 212 is vertically fixed in the opening of the protective frame 210. The protective frame 210 forms a ventilation cavity 211 through the partition 212. The ventilation cavity 211 facilitates the flow of air, and the ventilation cavity 211 is vertically arranged and is staggeredly distributed with the louver 110, which can prevent leaves from entering the gaps of the louver 110. Two parallel gas soft bags 213 are fixed in the ventilation cavity 211, and the outer periphery of the gas soft bag 213 is airtight and fixed to the inner side surface of the ventilation cavity 211.

[0048] The first air supply pipe 220 is fixed on the protective frame 210. The intake end of the first air supply pipe 220 is connected to an air pump, and the air pump is fixed on the protective frame 210. The outlet end of the first air supply pipe 220 is fixed with a branch pipe 221 that is used in cooperation with the ventilation cavity 211. That is to say, the ventilation cavity 211 is used in cooperation with the branch pipe 221.

[0049] The outlet end of the branch pipe 221 is fixed with two air guide pipes 222. The outlet ends of the air guide pipes 222 extend into the gas soft bag 213, and the connection part of the air guide pipe 222 and the gas soft bag 213 is sealed and fixed.

[0050] When the branch pipe 221 is inflated, the two gas soft bags 213 in the ventilation cavity 211 expand simultaneously until they abut against each other. When the branch pipe 221 is evacuated, the two gas soft bags 213 in the ventilation cavity 211 contract and return to their original positions.

[0051] It is easy to understand that when the air pump inflates the first air supply pipe 220, the two gas soft bags 213 in one ventilation cavity 211 can quickly expand and abut against each other. The inflated gas soft bags 213 clamp the leaves floating into the ventilation cavity 211, and at the same time block the contact between the leaves and the external air. Subsequently, when the first air supply pipe 220 is evacuated, the two gas soft bags 213 contract. At this time, the leaves fall into the protective frame 210 under the action of gravity, preventing the leaves from entering the box body 100 from the louver 110.

[0052] Specifically, as Figures 1 to 10 shown, the number of the partitions 212 is multiple, and the multiple partitions 212 are evenly spaced in the protective frame 210. The side surface of the partition 212 contacts the surface of the louver 110. That is to say, the length of the partition 212 can abut against the louver 110, making it difficult for the fallen objects to enter the louver 110.

[0053] A ventilation cavity 211 is formed between the adjacent partition plates 212, and two parallel gas soft bags 213 are fixed in each ventilation cavity 211;

[0054] It is easy to understand that multiple ventilation cavities 211 can disperse the flowing air. When the hot air flowing centrally in the box body 100 passes through the ventilation cavities 211, the hot air can flow dispersedly, avoiding heat concentration;

[0055] Specifically, as Figure 10 shown, a baffle 214 is fixed on the protection frame 210. The baffle 214 is a convex structure, which can prevent foreign objects from rubbing against the protection frame 210. An infrared sensor 215 is fixed on one side of the baffle 214 close to the ventilation cavity 211. The model of the infrared sensor 215 is KJT LT15-S30-3D1. The infrared sensor 215 is electrically connected to the air pump of the first air supply pipe 220 through a circuit. That is to say, the emitter of the infrared sensor 215 emits infrared rays of a certain frequency. When foreign impurities enter the ventilation cavity 211, after the infrared sensor 215 senses an object, the receiver receives the infrared rays and converts them into electrical signals, causing the air pump to start running. When no object is detected, the air pump is in a suspended state of operation, and it does not need to keep running all the time, which can reduce the loss of the equipment and save the use cost.

[0056] In the above embodiment, the object entering the protection frame 210 is detected by the infrared sensor 215. When the infrared sensor 215 detects an object, the first air supply pipe 220 fills and evacuates each branch pipe 221 through the air pump, so that the two gas soft bags 213 in the corresponding ventilation cavity 211 expand and abut against each other, and the object entering is clamped by the abutting surfaces of the gas soft bags 213. Then the gas soft bags 213 contract, and the object falls downward under the action of gravity and is intercepted in front of the shutter 110, making it difficult for foreign objects to enter the box body 100 and reducing the danger in case of a sudden fire.

[0057] Specifically, as Figures 1 to 14 shown, the protection component 200 further includes a collection tank 230, and the collection tank 230 is used to collect the objects that fall after entering the ventilation cavity 211, further reducing the danger of the objects passing through the shutter 110 and entering the box body 100;

[0058] The collection tank 230 is a rectangular plate with a hollow interior and an open top, and it is fixed at the bottom of the protection frame 210. An opening is provided at the bottom of the protection frame 210, and the bottom opening of the protection frame 210 coincides with the top opening of the collection tank 230. That is to say, the objects entering the ventilation cavity 211 can fall into the collection tank 230;

[0059] Specifically, as Figures 4 to 14As shown, a metal plate 2311 is fixed to the side of the collection groove 230 through a connecting plate 231. The connecting plate 231 is fixed to the side of the collection groove 230. A positioning plate 232 is fixed to the side of the protective frame 210. A chute for cooperating with the metal plate 2311 is opened at the bottom of the positioning plate 232. The chute of the positioning plate 232 facilitates the positioning of the metal plate 2311.

[0060] Specifically, as Figures 5 to 7 shown, a magnet is fixed in the chute of the positioning plate 232, and the metal plate 2311 can be magnetically adsorbed on the magnet in the chute of the positioning plate 232.

[0061] It is easy to understand that the collection groove 230 is convenient for disassembly. By sliding the metal plate 2311 on the collection groove 230 away from the magnet in the chute of the positioning plate 232, the collection groove 230 can be disassembled, and the objects intercepted in the collection groove 230 can be cleaned up uniformly.

[0062] In the above embodiment, the intercepted objects are collected by the collection groove 230. At the same time, the collection groove 230 is set as a detachable structure. Through the magnetic adsorption of the metal plate 2311 and the magnet in the chute of the positioning plate 232, the disassembly of the collection groove 230 can be realized, which is convenient for disassembling and cleaning the intercepted objects. At the same time, the installation method is simple, and the installation work can be completed without installation tools outdoors.

[0063] Specifically, as Figures 1 to 14 shown, the air outlet end of the first air supply pipe 220 is fixed with a second air supply pipe 223. That is to say, the first air supply pipe 220 and the second air supply pipe 223 share one air pump, which reduces the use cost and lightens the load-bearing burden of the structure.

[0064] The air outlet end of the second air supply pipe 223 extends into the collection groove 230, and a one-way valve 2231 is fixed on the air outlet end of the second air supply pipe 223. The one-way valve 2231 is used to pump air out of the collection groove 230, and at the same time, the one-way valve 2231 is used to prevent air from being inflated into the collection groove 230.

[0065] In the above embodiment, when the air pump inflates the first air supply pipe 220, the one-way valve 2231 of the second air supply pipe 223 can prevent external air from entering the collection groove 230. When the air pump pumps air out of the first air supply pipe 220, the second air supply pipe 223 pumps air out of the collection groove 230, which can increase the suction force in the ventilation cavity 211, accelerate the falling speed of the object after the gas soft bag 213 shrinks, increase the suction force on the falling object, and facilitate the collection of the object.

[0066] Specifically, as Figures 11 to 14As shown, a weight plate 2131 is fixed on each of the two gas soft bags 213 in the ventilation cavity 211. After the gas soft bags 213 are expanded, the weight plates 2131 can contact each other, and the weight plates 2131 are used to increase the contact force with the object;

[0067] It is easy to understand that when the gas soft bag 213 expands and contacts, the heavy pressure plate 2131 can increase the contact force during the contact, better isolate the object from the external air, and make the object fall into the collection tank 230 more easily;

[0068] Specifically, if Figure 14 As shown, each branch pipe 221 is fixed with a control valve 2211, and the control valve 2211 is used to control the inflated gas soft bag 213;

[0069] Specifically, if Figures 11 to 14 As shown, each of the heavy pressure plates 2131 is provided with a ventilation hole 2132, and the ventilation hole 2132 is used to maintain air circulation.

[0070] In the above embodiment, when encountering severe weather such as thunderstorms, the control valve 2211 is opened, and the air supply pipe 220 is inflated by the air pump to inflate the gas bag 213 until the pressure plates 2131 collide with each other, and then the control valve 2211 is closed to keep the gas bag 213 in the inflated state and the ventilation chamber 211 in a closed state, which can prevent rainwater from splashing into the box body 100 and prevent debris brought by strong winds from being blocked in the ventilation chamber 211. The ventilation holes 2132 can keep the air circulating in the box body 100 when the ventilation chamber 211 is closed, thereby better protecting the electrical equipment in the box body 100 and ensuring the safety of equipment operation.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
