A type of prefabricated substation

Abstract

This invention relates to the field of substation technology and discloses a prefabricated substation, comprising a main body with air outlets on both the left and right sides. The inclined fixing plate inside the main body and multiple bending frames at the bottom of the fixing plate guide hot air, transforming the disordered rising hot air into an orderly and uniformly oriented flow. This reduces the stagnation of hot air within the main body and the limited flow speed through the air outlets, ensuring stable exhaust of hot air while reducing the risk of overheating due to heat accumulation within the substation, thus improving heat dissipation and cooling efficiency within the main body.

Description

Technical Field

[0001] This invention relates to the field of substation technology, specifically a prefabricated substation. Background Technology

[0002] A prefabricated substation (also known as a prefabricated substation or prefabricated transformer substation) is a factory-prefabricated compact power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. It has the characteristics of moisture-proof, rust-proof, dust-proof, fire-proof, theft-proof, heat-insulating, fully enclosed, and mobile features, and is widely used in urban power grid renovation, mines, factories, oil and gas fields, wind power stations, and temporary power supply scenarios.

[0003] Typical prefabricated substations contain numerous high-voltage devices and are mostly enclosed structures. Since the ventilation of most enclosed prefabricated transformers relies solely on the ventilation openings on the surface of the enclosure, achieving ventilation and cooling through natural air circulation, when a large amount of heat is generated inside the substation, the hot air tends to stagnate within the substation, and the speed of its flow to the outside through the ventilation openings is limited. This can easily lead to excessive heat remaining inside the substation, making it difficult to dissipate quickly and causing it to linger for too long. This can result in excessively high temperatures inside the substation and also affect the working efficiency of the equipment within the substation. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated substation to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a prefabricated substation, comprising a main body, with air outlets on both the left and right sides of the main body, and further comprising:

[0007] The rotating mechanism is installed inside the main body and is used to guide the hot gas when the equipment inside the main body is working, so as to prevent the hot gas from accumulating inside the main body.

[0008] An auxiliary mechanism is installed on the side wall of the rotating mechanism to prevent hot gas from colliding and spreading when it rises during operation.

[0009] Furthermore, the main body includes:

[0010] The bootloader is installed and set inside the main body.

[0011] Furthermore, the rotating mechanism includes several support plates disposed at the bottom of the main body, and the rotating mechanism also includes:

[0012] The movable component is installed at the bottom of the support plate;

[0013] A rotating component is mounted on the side wall of the movable component.

[0014] Furthermore, the auxiliary mechanism includes two L-plates disposed on the side wall of the active component, and the auxiliary mechanism also includes:

[0015] A sliding assembly is installed between two L-plates.

[0016] Furthermore, the guiding component includes a fixed plate fixedly connected to the inner wall of the top of the main body, and several bending frames are fixedly connected to the bottom of the fixed plate, with the bending frames arranged symmetrically in pairs.

[0017] Furthermore, each set of bending frames is arranged at equal intervals, and a V-shaped plate is set between two bending frames. The V-shaped plate is fixedly connected to the fixing plate.

[0018] A bending plate is fixedly connected to the side of the bending frame away from the V-shaped plate, and the fixing plate is set at an angle inside the main body.

[0019] Furthermore, several support plates are arranged in pairs, symmetrically distributed with the center of the fixed plate as the center, and the four groups of support plates are arranged at equal distances.

[0020] The active component includes an inclined plate that is fixedly connected between two support plates.

[0021] Furthermore, a movable plate is slidably connected to the outer surface of the inclined plate, and a semi-circular groove is provided on the side wall of the movable plate;

[0022] The rotating assembly includes a middle plate rotatably connected to the side wall of the movable plate, and an inclined plate is fixedly connected to the bottom of the middle plate.

[0023] Furthermore, a linear spring is fixedly connected to the side wall of the L-plate, and the end of the linear spring away from the L-plate is fixedly connected to the side wall of the inclined plate.

[0024] The sliding assembly includes a T-shaped plate fixedly connected between two L-plates, and the side wall of the T-shaped plate has several rectangular grooves.

[0025] Furthermore, a spring frame is slidably connected to the bottom inner wall of the rectangular groove, the elastic end of the spring frame is fixedly connected to the bottom inner wall of the rectangular groove, and a rocking plate is rotatably connected inside the spring frame.

[0026] The swaying plate is positioned between the two bending frames.

[0027] The present invention has the following beneficial effects:

[0028] 1. In this invention, the inclined fixing plate inside the main body and the multiple bending frames at the bottom of the fixing plate can guide hot air, transforming the disordered rising hot air into an orderly and uniform flow. This reduces the situation where hot air stagnates inside the main body and its flow speed to the outside through the air outlet is limited. This ensures that the hot gas can be stably discharged to the outside, while reducing the situation where the temperature is too high due to heat accumulation in the substation, and improving the efficiency of heat dissipation and cooling inside the main body.

[0029] 2. In this invention, the rotating movable plate can reduce the downward retraction of hot air, and at the same time, the returning hot air can boost the gas flow guided by the bending frame. This reduces the retraction and stagnation of hot air, while further accelerating the flow speed of hot air and the discharge speed through the air outlet, thereby further improving the cooling efficiency of the internal heat of the main body.

[0030] 3. In this invention, when hot air passes through the narrow channel in the middle of the T-shaped plate, the hot air will enter the wide external area. At this time, the flow rate of the hot air will decrease instantly after acceleration. The reduced hot air will then flow along the guide of the inclined fixed plate and the bending frame. By slowing down the flow rate of the gas, the interaction and diffusion between the gas and the hot air flowing through the bottom of the fixed plate after passing through the inclined plate and the movable plate can be reduced. This ensures that the hot air can flow stably outward through the fixed plate, while improving the continuity of the hot air flow and exhaust, and improving the cooling efficiency.

[0031] 4. In this invention, when the gas flows outward through the bending frame, the shaking plate will block the two streams of gas at the outlets of the two bending frames. At the same time, the shaking plate will also shake under the flow of gas flowing out of the outlets of the two bending frames. At this time, the shaking plate can reduce the convergence and diffusion of the gas flowing out of the two bending frames between the outlets of the two bending frames, further reduce the diffusion of hot air at the outlets of the bending frames, and further enhance the continuity and flow intensity of the hot air being discharged outward.

[0032] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0047] 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.

[0048] Please see Figure 1 - Figure 11 As shown, the present invention is a prefabricated substation, including a main body 1, with air outlets 101 on both the left and right sides of the main body 1, and further including:

[0049] Rotating mechanism 2 is installed inside the main body 1 and is used to guide the hot gas when the equipment inside the main body 1 is working, so as to prevent the hot gas from accumulating inside the main body 1.

[0050] Auxiliary mechanism 3 is installed on the side wall of rotating mechanism 2 to prevent hot gas from colliding and spreading when it rises during operation of rotating mechanism 2.

[0051] Entity 1 includes:

[0052] The guide component 11 is installed inside the main body 1.

[0053] The rotating mechanism 2 includes several support plates 201 disposed at the bottom of the main body 1, and the rotating mechanism 2 also includes:

[0054] Active component 21 is installed at the bottom of support plate 201;

[0055] Rotating component 22 is mounted on the side wall of movable component 21.

[0056] The auxiliary mechanism 3 includes two L-plates 301 disposed on the side wall of the movable component 21, and the auxiliary mechanism 3 also includes:

[0057] The sliding component 31 is installed between the two L-plates 301.

[0058] The guide component 11 includes a fixing plate 111 fixedly connected to the inner wall of the top of the main body 1. Several bending frames 112 are fixedly connected to the bottom of the fixing plate 111, and the bending frames 112 are symmetrically distributed in pairs.

[0059] Each set of bending frames 112 is arranged at equal distances, and a V-shaped plate 114 is provided between two bending frames 112. The V-shaped plate 114 is fixedly connected to the fixing plate 111.

[0060] A bending plate 113 is fixedly connected to the side of the bending frame 112 away from the V-shaped plate 114. The fixing plate 111 is inclined inside the main body 1. Since the fixing plate 111 is inclined on the top inner wall of the main body 1, when more hot air flows upward and contacts the bottom of the fixing plate 111, some of the hot air will flow towards one of the air outlets 101 of the main body 1 under the guidance of the inclined side walls of the multiple bending frames 112.

[0061] Several support plates 201 are arranged in pairs, symmetrically distributed with the center of the fixed plate 111 as the center, and the four groups of support plates 201 are arranged at equal distances.

[0062] The active component 21 includes an inclined plate 211 fixedly connected between two support plates 201.

[0063] A movable plate 212 is slidably connected to the outer surface of the inclined plate 211, and a semi-circular groove is provided on the side wall of the movable plate 212.

[0064] The rotating assembly 22 includes an intermediate plate 221 rotatably connected to the side wall of the movable plate 212. An inclined plate 222 is fixedly connected to the bottom of the intermediate plate 221. When the movable plate 212 is subjected to a downward pushing force, the movable plate 212 will form a large angle with the inclined plate 211, as shown in the attached figure. Figure 8 In the state of being in motion, when the hot air folds back downwards, it will return to the bottom of the fixed plate 111 under the guidance of the upper semi-circular groove of the movable plate 212 and the inclined surface of the inclined plate 211.

[0065] A linear spring is fixedly connected to the side wall of L plate 301, and the end of the linear spring away from L plate 301 is fixedly connected to the side wall of inclined plate 211.

[0066] The sliding assembly 31 includes a T-shaped plate 311 fixedly connected between two L-plates 301. The side wall of the T-shaped plate 311 has several rectangular grooves. When the T-shaped plate 311 slides upward, a flow channel is formed between the T-shaped plate 311 and the inclined plate 211. At the same time, when hot air flows obliquely on the surface of the inclined plate 211, the hot air will pass through the narrow channel in the middle between the T-shaped plate 311 and the inclined plate 211 and flow faster.

[0067] A spring frame 312 is slidably connected to the bottom inner wall of the rectangular groove. The elastic end of the spring frame 312 is fixedly connected to the bottom inner wall of the rectangular groove. A rocking plate 313 is rotatably connected inside the spring frame 312.

[0068] The shaking plate 313 is positioned between the two bending frames 112. The shaking plate 313 will block the two streams of gas at the outlets of the two bending frames 112. At the same time, the shaking plate 313 will shake under the flow of gas flowing out of the outlets of the two bending frames 112.

[0069] When in use, the high-voltage equipment inside the substation generates a lot of heat during operation, which accumulates inside the main body 1. When a lot of heat is formed inside the main body 1, the hot gas will flow upward. At this time, the hot gas will be discharged outward through the air outlet 101. Meanwhile, the external gas will enter the main body 1 through the air inlet at the bottom of the observation door on the side wall of the main body 1, thereby achieving the purpose of cooling the heat inside the main body 1.

[0070] When the high-pressure equipment inside the main body 1 is working and generating a large amount of hot air, the rising hot air flows to the bottom of the fixed plate 111. Since the fixed plate 111 is inclined on the top inner wall of the main body 1, when a large amount of hot air flows upward and contacts the bottom of the fixed plate 111, some of the hot air will be guided by the inclined side walls of the multiple bending frames 112 to flow towards one of the air outlets 101 of the main body 1. At the same time, some hot air will flow through the inlet on the bending frame 112 and flow inside the bending frame 112. When it passes through the narrow channel of the outlet of the bending frame 112, the flow velocity of the gas flowing inside the bending frame 112 will increase, and it will draw the relatively slower external gas to be discharged outward towards one of the air outlets 101. Meanwhile, due to the openings of the V-shaped plate 114 and the bending plate 113 With the outlet fixing plate 111 facing the inclined direction of the bending frame 112, when hot air flows at the bottom of the fixing plate 111, the V-shaped plate 114 and the bent plate 113 can reduce the situation where hot air rises to the bottom of the fixing plate 111 and turns back to the other side of the hot air flow direction. At this time, the inclined fixing plate 111 inside the main body 1 and the multiple bending frames 112 at the bottom of the fixing plate 111 can guide the hot air, transforming the disorderly rising hot air into an orderly and uniform flow. This can reduce the situation where hot air stagnates in the main body 1 and the flow speed to the outside through the air outlet 101 is limited. This can ensure that the hot gas can be stably discharged to the outside, while reducing the situation where the temperature is too high due to the accumulation of heat in the substation, and improving the heat dissipation and cooling efficiency inside the main body 1.

[0071] When a large amount of hot air rises and comes into contact with the bottom of the fixed plate 111, the rising hot air will diffuse and reflux downwards after hitting the fixed plate 111. When a large amount of hot air refluxes downwards, the reflux of hot air will generate a downward pushing force on the movable plate 212. When the movable plate 212 is subjected to the downward pushing force, the movable plate 212 will form a large angle with the inclined plate 211, as shown in the attached figure. Figure 8 In the state of the hot air, when the hot air returns downward, it will return to the bottom of the fixed plate 111 under the guidance of the semi-circular groove on the upper part of the movable plate 212 and the inclined surface of the inclined plate 211. At the same time, the rotating movable plate 212 can reduce the downward return of hot air, and can also use the returning hot air to boost the gas flow rate guided by the bending frame 112. This can reduce the hot air return and stagnation, further accelerate the flow speed of hot air and the discharge speed through the air outlet 101, and further improve the cooling efficiency of the heat inside the main body 1.

[0072] When one side of the movable plate 212 rotates downwards under the push of hot air, the side of the movable plate 212 without the semicircular groove will tilt upwards. When the movable plate 212 tilts upwards, it pushes the L-plate 301, causing the T-shaped plate 311 to slide upwards. When the T-shaped plate 311 slides upwards, a flow channel is formed between the T-shaped plate 311 and the inclined plate 211. At the same time, when the hot air flows obliquely on the surface of the inclined plate 211, the hot air will pass through the narrow channel in the middle between the T-shaped plate 311 and the inclined plate 211 and flow faster. Then, when the hot air passes through the T-shaped plate... When the narrow passage in the middle of 311 is reached, hot air will enter the wide external area. At this time, the flow rate of the hot air will decrease instantly after acceleration. The reduced hot air will then flow along the guide of the inclined fixed plate 111 and the bending frame 112. By slowing down the flow rate of the gas, the interaction and diffusion between the gas and the hot air flowing through the bottom of the fixed plate 111 after passing through the inclined plate 111 and the movable plate 212 can be reduced. This ensures that the hot air can flow stably outward through the fixed plate 111, while improving the continuity of the hot air flow and exhaust, and improving the cooling efficiency.

[0073] When the L-plate 301 drives the T-plate 311 to slide upward, the T-plate 311 will drive the swaying plate 313 to slide upward through the spring frame 312, so that the swaying plate 313 is at the outlet between the two bending frames 112. Then, when the gas flows outward through the bending frame 112, the swaying plate 313 will block the two streams of gas at the outlet of the two bending frames 112. At the same time, the swaying plate 313 will also sway under the flow of gas flowing out of the outlet of the two bending frames 112. At this time, the swaying plate 313 can reduce the convergence and diffusion of the gas flowing out of the two bending frames 112 between the outlets of the two bending frames 112, further reducing the diffusion of hot air at the outlet of the bending frame 112, and further enhancing the continuity and flow intensity of the hot air being discharged outward.
