Description

Technical Field

[0001] This invention belongs to the field of substation technology, and particularly relates to a prefabricated substation with automatic circulating heat dissipation. Background Technology

[0002] Prefabricated substations, also known as box-type substations or prefabricated transformer substations, are factory-prefabricated, compact indoor and outdoor power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices according to a specific wiring scheme. They organically combine transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, heat-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. Particularly suitable for urban power grid construction and renovation, they represent a new type of substation that has emerged after traditional civil engineering substations. They are also used in mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system.

[0003] In current prefabricated substations, cooling fans operate during heat dissipation. The fans draw heat from the substation's energy storage equipment inside the protection box into the exhaust duct. As the hot air is expelled, it drives the active fan blades to rotate, which in turn drives the fixed ring and connecting shaft to rotate. This, in turn, drives the active sprocket, chain, and driven sprocket to rotate, which in turn drives the rotating shaft and pressurizing blades to rotate. This accelerates the incoming cold air, allowing it to enter the protection box and dissipate heat from the equipment. The heat is then expelled through the exhaust duct, forming a circulating cooling system. However, during the cooling process, there is localized heat dissipation, leading to uneven heat dissipation. The hot air cannot fully contact the cold source to improve the cooling effect, and the cooled gas cannot fully adhere to the heat dissipation elements, affecting the efficiency of internal heat dissipation. Summary of the Invention

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0016] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0017] like Figures 1-6The diagram shown illustrates the structure of an automatic circulating cooling prefabricated substation according to an embodiment of the present invention. It includes a housing 1, a base plate 2, an outer shell 4, a directional airflow mechanism 100, a water cooling mechanism 200, a circulating airflow mechanism 300, and a uniform heat dissipation mechanism 400. The base plate 2 is fixedly installed on the inner wall of the housing 1. The outer shell 4 is symmetrically arranged on the outer side of the housing 1. A baffle 11 is installed at the top of the housing 1. The housing 1, outer shell 4, and baffle 11 constitute a flow channel 5 to facilitate gas movement. Multiple sets of directional airflow mechanisms 100 are provided. The directional air guiding mechanism 100 is rotatably mounted on the housing 1 and the outer shell 4 to transport hot air from the bottom upwards; the water cooling mechanism 200 is mounted on the side of the air guide hole 6 to cool the gas moving to the top; the circulating flow guiding mechanism 300 is arranged on the water cooling mechanism 200 to facilitate the outward discharge of water droplets generated during gas atomization; the uniform heat dissipation mechanism 400 is arranged inside the housing 1, and the top of the uniform heat dissipation mechanism 400 communicates with the water cooling mechanism 200 to facilitate the return of cooled gas to the housing 1.

[0018] The automatic circulating heat dissipation box-type substation provided in this application can send the heat generated inside the substation upward from multiple directions during actual use, avoiding the problem of uneven heat dissipation caused by local heat dissipation. It not only effectively extends the movement path of the gas, allowing the hot air to fully contact the water mist and improve the cooling effect, but also allows the cooled gas to adhere to the internal components of the substation, so as to control the ambient temperature inside the substation, thereby enabling the substation to work efficiently.

[0019] In one embodiment of the present invention, an isolation cavity 3 is also provided at the bottom end of the base plate 2 to prevent the base plate 2 from directly contacting the ground and to effectively prevent the base plate 2 and the components inside the housing 1 from getting damp and affecting their normal operation.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the directional air guiding mechanism 100 includes an external gear ring 7 rotatably mounted on the housing 1, a longitudinal rotating shaft 8 rotatably mounted on the outer casing 4, and a drive wheel 9 fixedly arranged on the longitudinal rotating shaft 8 and meshing with the external gear ring 7. The housing 1 is provided with a plurality of air guide holes 6 evenly to facilitate gas flow; Multiple fan blades 10 are installed on the longitudinal rotating shaft 8 along the axial direction, and complete the airflow delivery when rotating.

[0021] In the specific implementation of this embodiment, the accompanying drawings are provided. Figure 1 as well as Figure 2It is known that there are 4 longitudinal rotating shafts 8, but 6, 8 or 10 can also be selected and adjusted as needed. During operation, one of the longitudinal rotating shafts 8 can be selected and connected to an external motor via a coupling. When the external motor is working, the longitudinal rotating shaft 8 at the corresponding position rotates along the outer casing 4. Since the drive wheel 9 arranged on the longitudinal rotating shaft 8 meshes with the external gear ring 7, when the external gear ring 7 rotates along the housing 1, the drive wheels 9 at other positions and the longitudinal rotating shaft 8 rotate synchronously. The fan blades 10 also move with the longitudinal rotating shaft 8 to transport the hot air overflowing from the air vent 6 inside the substation upward.

[0022] like Figure 1 and Figure 4 As shown, in another preferred embodiment of the present invention, the water cooling mechanism 200 includes an inclined plate 12 and an air guide plate 13 fixedly installed inside the air guide hole 6, and an atomizing nozzle arranged on the air guide plate 13. The inclined plate 12 is provided with rectangular holes for airflow to pass through; The air guide plate 13 is composed of multiple arc plates connected end to end, so as to extend the movement path of the gas, so that the hot air and water mist can come into full contact and improve the cooling effect. A water tank 19 is installed on the outside of the air guide hole 6, and a pump body 21 is installed on the top of the water tank 19. The pump body 21 is also connected to multiple atomizing nozzles through a diversion pipe 22.

[0023] In the specific implementation of this embodiment, existing refrigeration equipment is also arranged in the water tank 19 as needed to cool the exported warm water. When the hot air passes through the rectangular hole set on the inclined plate 12 and continues to move along the space formed by the inclined plate 12 and the air guide plate 13, the pump body 21 works to draw out the cooling water in the water tank 19 and make the cooling water flow along the diversion pipe 22, and finally spray it out from the atomizing nozzle to fully contact the passing hot air.

[0024] In addition, a support plate 18 is fixedly installed on the outside of the box 1. The upper surface of the support plate 18 is fixedly connected to the water tank 19. A stiffening plate 20 is also installed at the bottom of the support plate 18 to improve the load-bearing capacity of the support plate 18.

[0025] like Figure 5 As shown, in another preferred embodiment of the present invention, absorbent cotton 17 is also installed on the inner side of the top of the inclined plate 12 and the air guide plate 13.

[0026] In the specific implementation of this embodiment, the absorbent cotton 17 is used to absorb the moisture contained in the gas.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, in another preferred embodiment of the present invention, the circulation guiding mechanism 300 includes an inner flow channel 14 disposed in the inclined plate 12 and a drain hole 15 disposed on the inclined plate 12 and communicating with the inner flow channel 14. A return pipe 16 is installed on the outside of the inclined plate 12, and the return pipe 16 is connected to the water tank 19.

[0028] In the specific implementation of this embodiment, after the hot air comes into contact with the water mist, the air temperature drops and moves obliquely upward along the inclined plate 12 and the air guide plate 13. The water droplets fall through the water drop hole 15 and flow along the inner flow channel 14, and are introduced into the water tank 19 through the set return pipe 16.

[0029] like Figure 1 and Figure 5 As shown, in another preferred embodiment of the present invention, the uniform heat dissipation mechanism 400 includes a longitudinal column 24 fixedly installed in the housing 1 and a cooler 23 arranged at the top of the longitudinal column 24 and connected to the inclined plate 12 and the air guide plate 13. An air guide cavity 25 is provided axially inside the longitudinal column 24; The bottom plate 2 has a flow divider 26 communicating with the air guide chamber 25 on its inner side, and a plurality of exhaust holes 27 communicating with the flow divider 26 are also evenly arranged on the bottom plate 2.

[0030] In the specific implementation of this embodiment, the air after removing water vapor enters the cooler 23 for cooling again. The cooled air moves downward along the air guide cavity 25 set on the longitudinal column 24, and after entering the diversion cavity 26, it is finally discharged upward from the exhaust hole 27. The cooled air is cooled when it passes through the internal components of the substation.

[0031] In summary, during use, the heat emitted by the components inside the housing 1 mixes with the gas to form hot air. One of the longitudinal shafts 8 is selectively connected to an external motor via a coupling. When the external motor operates, the corresponding longitudinal shaft 8 rotates along the outer casing 4. Since the drive wheel 9 on the longitudinal shaft 8 meshes with the external gear ring 7, when the external gear ring 7 rotates along the housing 1, the drive wheels 9 at other positions and the longitudinal shaft 8 rotate synchronously. The fan blades 10 also move with the longitudinal shaft 8 to transport the hot air overflowing from the air vent 6 inside the substation upwards. As the hot air passes through the rectangular hole on the inclined plate 12 and continues to move along the space formed by the inclined plate 12 and the air vent 13, the pump 21 operates to extract cooling water from the water tank 19 and allows the cooling water to flow along the diversion pipe 22, finally spraying it out from the atomizing nozzle, making full contact with the passing hot air. Through the absorbent cotton 17, the water can absorb the heat contained in the gas. Moisture-free air enters the cooler 23 after passing the top of the inclined plate 12 and the air guide plate 13, where it is cooled again. The cooled air then moves downward along the air guide cavity 25 set on the longitudinal column 24, and after entering the diversion cavity 26, it is finally discharged upward from the exhaust port 27. The cooled air cools the internal components of the substation as it passes through them. The above process is repeated to achieve internal circulating heat dissipation. In addition, after the hot air comes into contact with the water mist, the water droplets fall through the drain hole 15 and flow along the inner flow channel 14, and are guided into the water tank 19 through the set return pipe 16. In actual use, this application can send the heat generated inside the substation upward from multiple directions, avoiding the problem of uneven heat dissipation caused by local heat dissipation. It not only effectively extends the movement path of the gas, allowing the hot air to fully contact the water mist and improve the cooling effect, but also allows the cooled gas to adhere to the internal components of the substation, so as to control the ambient temperature inside the substation, thereby enabling the substation to work efficiently.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
