Description

Technical Field

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

[0002] A prefabricated substation is a complete set of power distribution equipment that combines high-voltage switchgear, power transformers, and low-voltage power distribution equipment in one or more boxes according to different wiring methods. Currently, most prefabricated substations operate in a fully enclosed manner. When a prefabricated substation is put into use, the heat generated by the internal components cannot be quickly dissipated, resulting in excessively high internal temperatures. In severe cases, this can cause component failures. Therefore, a detachable prefabricated prefabricated substation is proposed to improve the ease of installation and to automatically adjust the heat dissipation efficiency based on the internal temperature of the substation, thereby ensuring the safe operation of the prefabricated substation. Summary of the Invention

[0003] To address the problems in the existing technology, this invention provides a detachable prefabricated box-type substation that can automatically adjust its heat dissipation efficiency according to the temperature of the internal space of the box-type substation, thereby ensuring the safety of the box-type substation in use.

[0004] The technical solution adopted by the present invention to solve its technical problem is a detachable prefabricated box-type substation, including an upward-opening box body. The box body is connected by several sets of vertically arranged partitions. Adjacent partitions are detachably connected. The bottom of the box body is connected to a bottom plate. The upper surface of the box body is provided with a horizontally arranged cover plate. The cover plate is detachably connected to the top of the partitions. The upper surface of the cover plate is provided with symmetrically inclined heat insulation plates. The upper edges of two sets of heat insulation plates are fixedly connected. The lower surface of the heat insulation plates is fixedly connected with two sets of triangular baffles. The housing is equipped with several sets of hydraulic lifting structures. The output end of the hydraulic lifting structure is detachably connected to the lower surface of the heat insulation plate. The upper surface of the cover plate is equipped with a heat dissipation structure. The lower surface of the cover plate is fixedly connected with a thermal expansion structure. The lower end of the heat dissipation structure passes through the cover plate and contacts the thermal expansion structure.

[0005] By adopting the above technical solution, the installation convenience of the prefabricated substation can be improved by relying on the base plate, cover plate and several sets of partitions, and the assembly of the box body can be facilitated. When the enclosure is assembled and put into use, the components inside the enclosure will generate heat during use. At this time, the heat dissipation structure can transfer the heat inside the enclosure out, thereby completing the heat dissipation inside the enclosure and ensuring the safety of the components. When the internal temperature of the enclosure reaches a certain level, the heat dissipation structure can no longer meet the heat dissipation requirements. The thermal expansion structure drives the hydraulic lifting structure to work. When the hydraulic lifting structure works, it moves the heat insulation plate upward, which in turn moves the baffle upward. As the heat insulation plate moves upward, the distance between the heat insulation plate and the cover plate increases, thereby improving the air circulation between the heat insulation plate and the cover plate and further improving the heat dissipation efficiency of the heat dissipation structure. At the same time, it can automatically adjust the heat dissipation efficiency according to the temperature of the internal space of the prefabricated substation to ensure the safety of the prefabricated substation in use.

[0006] Specifically, the hydraulic lifting structure includes several sets of vertically arranged first hydraulic telescopic rods and second hydraulic telescopic rods. The fixed ends of the first hydraulic telescopic rods and second hydraulic telescopic rods pass through the cover plate and are fixedly connected to the cover plate. The output ends of the first hydraulic telescopic rods and second hydraulic telescopic rods are fixedly connected to the lower surface of the heat insulation plate. The fixed ends of the first hydraulic telescopic rods and second hydraulic telescopic rods are all connected to a first connector. The first connector is connected to the thermal expansion structure through a pipeline.

[0007] By adopting the above technical solution, when the temperature inside the box is high, the heat dissipation structure cannot meet the heat dissipation requirements. The heat inside the box drives the thermal expansion structure to work. When the thermal expansion structure works, it connects with the first hydraulic telescopic rod and the second hydraulic telescopic rod through the pipes and the first joint, and drives the output ends of the first hydraulic telescopic rod and the second hydraulic telescopic rod to extend. At the same time, it drives the heat insulation plate to move up. As the heat insulation plate moves up, the distance between the heat insulation plate and the cover plate increases, thereby improving the air circulation between the heat insulation plate and the cover plate, and further improving the heat dissipation efficiency of the heat dissipation structure.

[0008] Specifically, the thermal expansion structure includes a liquid storage tank fixedly connected to the lower surface of a cover plate, the liquid storage tank being filled with a thermal expansion fluid, and a number of second connectors being provided at the lower end of the liquid storage tank, the second connectors being connected to the first connectors through pipelines.

[0009] By adopting the above technical solution, when the temperature inside the box is high, the heat dissipation structure cannot meet the heat dissipation requirements. As the temperature inside the box rises, the thermal expansion fluid in the liquid storage tank expands. The thermal expansion fluid enters the first hydraulic telescopic rod and the second hydraulic telescopic rod through the second joint, the pipeline, and the first joint, and drives the output ends of the first hydraulic telescopic rod and the second hydraulic telescopic rod to extend, thereby improving the heat dissipation efficiency of the heat dissipation structure. It should be noted that the liquid storage tank described in this invention can be made of copper.

[0010] Specifically, the heat dissipation structure includes several sets of heat dissipation fins fixedly connected to the upper surface of the cover plate. The heat dissipation fins are vertically arranged, and the lower end of the heat dissipation fins passes through the cover plate and is located inside the liquid storage tank. A cleaning structure is fixedly connected to the surface of the cover plate, and the cleaning structure is used to clean the heat dissipation fins.

[0011] By adopting the above technical solution, when the cabinet is assembled and put into use, the components inside the cabinet will generate heat during use. As the temperature inside the cabinet rises, the heat inside the cabinet is absorbed by the liquid storage tank and the thermal expansion fluid. At the same time, the heat is transferred from the liquid storage tank by the heat sink and dissipated through the heat sink, thereby ensuring the safety of the components inside the cabinet. As the temperature inside the tank rises, the thermally expanding fluid in the storage tank expands, driving the output ends of the first and second hydraulic telescopic rods to extend. At the same time, the heat insulation plate moves upward. As the heat insulation plate moves upward, the distance between the heat insulation plate and the cover plate increases, thereby improving the airflow between the heat insulation plate and the cover plate and further improving the heat dissipation efficiency of the heat sink. The cleaning structure makes it easy to clean the heat sink, ensuring its heat dissipation effect.

[0012] Specifically, the cleaning structure includes a vertically arranged cleaning plate, and one side of the cleaning plate is provided with several sets of slots, which correspond to the heat sink. The cleaning plate has sliding grooves at both ends. The cover plate has a first rotating shaft and a second rotating shaft. Both ends of the first rotating shaft and the second rotating shaft are rotatably connected to vertically arranged support rods. The lower ends of the support rods are fixedly connected to the upper surface of the cover plate. Both ends of the first rotating shaft are connected to a first pulley, and both ends of the second rotating shaft are connected to a second pulley. The outer side of the first pulley is provided with a transmission belt. One end of the transmission belt passes through the sliding groove, wraps around the second pulley, and is fixedly connected to one side of the cleaning plate. The other end of the transmission belt is fixedly connected to the side of the cleaning plate away from the second rotating shaft. One end of the first rotating shaft is fixedly connected to a gear. The upper end of the first hydraulic telescopic rod is provided with a drive structure, which meshes with the gear for transmission.

[0013] By adopting the above technical solution, when the temperature inside the box is high, the thermal expansion fluid in the storage tank expands and drives the output ends of the first hydraulic telescopic rod and the second hydraulic telescopic rod to extend. When the output end of the first hydraulic telescopic rod moves upward, it drives the drive structure to move upward synchronously. The drive structure and gear meshing drive the first rotating shaft to rotate in the opposite direction. When the first rotating shaft rotates in the opposite direction, the first pulley and the transmission belt drive the second pulley to rotate in the opposite direction. When the transmission belt moves, it drives the cleaning plate to move. As the cleaning plate moves, the grooves clean both sides of the heat sink, thereby ensuring the heat dissipation effect of the heat sink. The support rods can ensure the overall stability of the first and second rotating shafts.

[0014] Specifically, the drive structure includes a connecting block, which is fixedly connected to the outer side of the output end of the first hydraulic telescopic rod. A vertically arranged rack is fixedly connected to one side of the connecting block, and the lower end of the rack passes through the cover plate and is located inside the housing. The rack meshes with a gear for transmission.

[0015] By adopting the above technical solution, when the output end of the first hydraulic telescopic rod moves upward, it drives the connecting block and the rack to move upward synchronously. As the rack moves upward, the rack meshes with the gear, thereby driving the first rotating shaft to rotate and driving the cleaning plate to move to clean the heat sink. When the temperature inside the housing decreases, the thermal expansion fluid stops expanding. At the same time, the output ends of the first and second hydraulic telescopic rods move down to reset. When the output end of the first hydraulic telescopic rod moves down, the rack engages with the gear again, driving the cleaning plate to reset and move, thus facilitating the cleaning of the heat sink again. Simultaneously, as the first and second hydraulic telescopic rods reset and move down, the heat insulation plate resets and moves down synchronously, thus facilitating the return to the initial state.

[0016] Specifically, a storage box is fixedly connected to the lower surface of the cover plate, and a through hole is provided on the upper surface of the cover plate, which communicates with the interior of the storage box. A discharge port is provided on one side of the storage box, which passes through a partition. A horizontally arranged spiral feeding rod is provided inside the storage box. The end of the spiral feeding rod away from the discharge port passes through the storage box and is rotatably connected to the storage box. A one-way bearing is fixedly connected to the end of the spiral feeding rod near the discharge port. A first pulley is fixedly connected to the one-way bearing. A second pulley is fixedly connected to the end of the first rotating shaft near the first pulley. The first pulley and the second pulley are driven by a transmission belt.

[0017] By adopting the above technical solution, when the transmission belt moves, it drives the cleaning plate to move. When the cleaning plate moves, it cleans both sides of the heat sink by relying on the slot. When the cleaning plate moves to a certain position, the cleaning plate moves the dust and other impurities on the heat sink into the through hole. At the same time, the dust and other impurities fall into the storage box, which facilitates the storage of the impurities cleaned on the heat sink. When the output end of the first hydraulic telescopic rod moves upward, it drives the first rotating shaft to rotate. When the first shaft rotates, it drives the first pulley to rotate by the second pulley and the transmission belt. At this time, the first pulley cannot drive the screw feed rod to rotate because of the one-way bearing. When the temperature inside the box decreases, the output end of the first hydraulic telescopic rod resets and moves downward. It drives the first rotating shaft to rotate in the forward direction by means of the rack and gear. When the first rotating shaft rotates in the forward direction, it drives the first pulley to rotate by means of the second pulley and the transmission belt. At this time, the first pulley drives the spiral feeding rod to rotate by means of the one-way bearing. When the spiral feeding rod rotates, it conveys the dust and other impurities in the storage box. As the spiral feeding rod rotates, it outputs the dust in the storage box to the discharge port. The dust and other impurities are discharged to the outside of the box by means of the discharge port, thereby further improving the convenience of use. The screw feeder can block the discharge port to prevent garbage and other impurities from entering the storage box through the discharge port; It should be noted that the bottom of the storage box described in this invention is arc-shaped, which facilitates the cleaning of dust and other impurities inside the storage box when the spiral cleaning rod rotates.

[0018] Specifically, several sets of elastic protective nets are fixedly connected between the upper surface of the cover plate and the lower surface of the heat insulation plate.

[0019] By adopting the above technical solution, the elastic protective net can protect the space between the cover plate and the insulation plate, preventing birds from entering the insulation plate to build nests and thus creating safety hazards.

[0020] Specifically, the outer side of the enclosure is equipped with an inspection door.

[0021] By adopting the above technical solution, the access port facilitates maintenance personnel to enter the enclosure and inspect and maintain the components inside.

[0022] The beneficial effects of this invention are: The present invention discloses a detachable prefabricated box-type substation. As the temperature inside the box rises, the thermal expansion fluid in the storage tank expands, driving the output ends of the first and second hydraulic telescopic rods to extend. At the same time, the heat insulation plate moves upward. As the heat insulation plate moves upward, the distance between the heat insulation plate and the cover plate increases, thereby improving the air circulation between the heat insulation plate and the cover plate and further improving the heat dissipation efficiency of the heat sink. At the same time, the heat dissipation efficiency can be automatically adjusted according to the temperature of the internal space of the box-type substation to ensure the safety of the box-type substation in use. The present invention discloses a detachable prefabricated box-type substation. When the temperature inside the box is high, the thermal expansion fluid in the storage tank expands and drives the output ends of the first and second hydraulic telescopic rods to extend. When the output end of the first hydraulic telescopic rod moves upward, it drives the rack to move upward synchronously. The rack and gear meshing drives the first rotating shaft to rotate in the opposite direction. When the first rotating shaft rotates in the opposite direction, the first pulley and the transmission belt drive the second pulley to rotate in the opposite direction. When the transmission belt moves, it drives the cleaning plate to move. As the cleaning plate moves, the grooves clean both sides of the heat sink, thereby ensuring the heat dissipation effect of the heat sink. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] To facilitate automatic adjustment of heat dissipation efficiency based on the internal temperature of the prefabricated substation and ensure its safe operation, as one embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 5 As shown, the present invention discloses a detachable prefabricated box-type substation, comprising an upward-opening box 1, the box 1 being connected by several sets of vertically arranged partitions, adjacent partitions being detachably connected, a bottom plate 2 being connected to the bottom of the box 1, a horizontally arranged cover plate 3 being provided on the upper surface of the box 1, the cover plate 3 being detachably connected to the top of the partitions, a symmetrically inclined heat insulation plate 4 being provided on the upper surface of the cover plate 3, the upper edges of two sets of heat insulation plates 4 being fixedly connected, and two sets of triangular baffles 5 being fixedly connected to the lower surface of the heat insulation plate 4. The housing 1 is equipped with several sets of hydraulic lifting structures. The output end of the hydraulic lifting structure is detachably connected to the lower surface of the heat insulation plate 4. The upper surface of the cover plate 3 is equipped with a heat dissipation structure. The lower surface of the cover plate 3 is fixedly connected with a thermal expansion structure. The lower end of the heat dissipation structure passes through the cover plate 3 and contacts the thermal expansion structure.

[0027] When in use, the base plate 2, cover plate 3 and several sets of partitions can improve the ease of installation of the prefabricated substation and facilitate the assembly of the enclosure 1. When the enclosure 1 is assembled and put into use, the components inside the enclosure 1 will generate heat during use. At this time, the heat dissipation structure can transfer the heat inside the enclosure 1 to the outside, thereby completing the heat dissipation inside the enclosure 1 and ensuring the safety of the components. When the temperature inside the enclosure 1 reaches a certain level, the heat dissipation structure can no longer meet the heat dissipation requirements. The thermal expansion structure drives the hydraulic lifting structure to work. When the hydraulic lifting structure works, it moves the heat insulation plate 4 upward. When the heat insulation plate 4 moves upward, it moves the baffle 5 upward simultaneously. At the same time, as the heat insulation plate 4 moves upward, the distance between the heat insulation plate 4 and the cover plate 3 increases, thereby improving the air circulation between the heat insulation plate 4 and the cover plate 3, further improving the heat dissipation efficiency of the heat dissipation structure. At the same time, it can automatically adjust the heat dissipation efficiency according to the temperature of the internal space of the prefabricated substation, ensuring the safety of the prefabricated substation in use.

[0028] To facilitate the upward movement of the heat insulation plate 4, for example, such as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the present invention also includes a hydraulic lifting structure comprising several sets of vertically arranged first hydraulic telescopic rods 6 and second hydraulic telescopic rods 7. The fixed ends of the first hydraulic telescopic rods 6 and second hydraulic telescopic rods 7 pass through the cover plate 3 and are fixedly connected to the cover plate 3. The output ends of the first hydraulic telescopic rods 6 and second hydraulic telescopic rods 7 are fixedly connected to the lower surface of the heat insulation plate 4. The fixed ends of the first hydraulic telescopic rods 6 and second hydraulic telescopic rods 7 are all connected to a first connector 8. The first connector 8 is connected to the thermal expansion structure through a pipeline.

[0029] When the temperature inside the housing 1 is high during use, the heat dissipation structure cannot meet the heat dissipation requirements. The heat inside the housing 1 drives the thermal expansion structure to work. When the thermal expansion structure works, it connects with the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 through the pipes and the first connector 8, and drives the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 to extend. At the same time, it drives the heat insulation plate 4 to move upward. As the heat insulation plate 4 moves upward, the distance between the heat insulation plate 4 and the cover plate 3 increases, thereby improving the air circulation between the heat insulation plate 4 and the cover plate 3, and further improving the heat dissipation efficiency of the heat dissipation structure.

[0030] To facilitate the extension of the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7, for example, as shown... Figure 2 , Figure 3 , Figure 4 As shown, the present invention also includes a liquid storage tank 9 fixedly connected to the lower surface of the cover plate 3, the liquid storage tank 9 being filled with a thermally expanding fluid, and a plurality of second connectors 10 being provided at the lower end of the liquid storage tank 9, the second connectors 10 being connected to the first connector 8 through pipelines.

[0031] When in use, when the temperature inside the housing 1 is high, the heat dissipation structure cannot meet the heat dissipation requirements. As the temperature inside the housing 1 rises, the thermal expansion fluid in the liquid storage tank 9 expands. The thermal expansion fluid enters the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 through the second connector 10, the pipeline, and the first connector 8, and drives the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 to extend, thereby improving the heat dissipation efficiency of the heat dissipation structure. It should be noted that the liquid storage tank 9 described in this invention can be made of copper.

[0032] To further improve the heat dissipation efficiency of the heat sink 11, for example, such as Figure 3 , Figure 4 , Figure 5As shown, the present invention also includes a plurality of heat dissipation fins 11 fixedly connected to the upper surface of the cover plate 3. The heat dissipation fins 11 are vertically arranged, and the lower end of the heat dissipation fins 11 passes through the cover plate 3 and is located inside the liquid storage tank 9. A cleaning structure is fixedly connected to the surface of the cover plate 3, and the cleaning structure is used to clean the heat dissipation fins 11.

[0033] When the enclosure 1 is assembled and put into use, the components inside the enclosure 1 will generate heat during use. As the temperature inside the enclosure 1 rises, the heat inside the enclosure 1 is absorbed by the liquid storage tank 9 and the thermal expansion fluid. At the same time, the heat is transferred from the liquid storage tank 9 by the heat sink 11 and dissipated through the heat sink 11, thereby ensuring the safety of the components inside the enclosure 1. As the temperature inside the housing 1 rises, the thermal expansion fluid in the liquid storage tank 9 expands, driving the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 to extend. At the same time, the heat insulation plate 4 moves upward. As the heat insulation plate 4 moves upward, the distance between the heat insulation plate 4 and the cover plate 3 increases, thereby improving the airflow between the heat insulation plate 4 and the cover plate 3, and further improving the heat dissipation efficiency of the heat sink 11. The cleaning structure makes it easy to clean the heat sink 11, ensuring the heat dissipation effect of the heat sink 11.

[0034] To facilitate cleaning of the heat sink 11, for example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the present invention also includes a cleaning structure comprising a vertically arranged cleaning plate 12, wherein one side of the cleaning plate 12 is provided with a plurality of slots 13, the slots 13 corresponding to the heat sink 11; The cleaning plate 12 has sliding grooves 20 at both ends. The cover plate 3 has a first rotating shaft 14 and a second rotating shaft 15. The first rotating shaft 14 and the second rotating shaft 15 are rotatably connected to vertically arranged support rods 16 at both ends. The lower end of the support rods 16 is fixedly connected to the upper surface of the cover plate 3. The first rotating shaft 14 has a first pulley 17 at both ends. The second rotating shaft 15 has a second pulley 18 at both ends. The outer side of the first pulley 17 is provided with a transmission belt 19. One end of the transmission belt 19 passes through the sliding groove 20, wraps around the second pulley 18, and is fixedly connected to one side of the cleaning plate 12. The other end of the transmission belt 19 is fixedly connected to the side of the cleaning plate 12 away from the second rotating shaft 15. A gear 21 is fixedly connected to one end of the first rotating shaft 14. The upper end of the first hydraulic telescopic rod 6 is provided with a drive structure. The drive structure meshes with the gear 21 for transmission.

[0035] When in use, when the temperature inside the housing 1 is high, the thermal expansion fluid in the liquid storage tank 9 expands and drives the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 to extend. When the output end of the first hydraulic telescopic rod 6 moves upward, it drives the drive structure to move upward synchronously. The drive structure meshes with the gear 21 and the transmission belt 19 to drive the first rotating shaft 14 to rotate in the opposite direction. When the first rotating shaft 14 rotates in the opposite direction, the first pulley 17 and the transmission belt 19 drive the second pulley 18 to rotate in the opposite direction. When the transmission belt 19 moves, it drives the cleaning plate 12 to move. As the cleaning plate 12 moves, the slots 13 clean both sides of the heat sink 11, thereby ensuring the heat dissipation effect of the heat sink 11. The support rod 16 can ensure the overall stability of the first rotating shaft 14 and the second rotating shaft 15.

[0036] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes a driving structure comprising a connecting block 22, the connecting block 22 being fixedly connected to the outer side of the output end of the first hydraulic telescopic rod 6, and a vertically arranged rack 23 being fixedly connected to one side of the connecting block 22, the lower end of the rack 23 passing through the cover plate 3 and located inside the housing 1, and the rack 23 meshing with the gear 21 for transmission.

[0037] When in use, when the output end of the first hydraulic telescopic rod 6 moves upward, it drives the connecting block 22 and the rack 23 to move upward synchronously. As the rack 23 moves upward, the rack 23 meshes with the gear 21, thereby driving the first rotating shaft 14 to rotate and driving the cleaning plate 12 to move to clean the heat sink 11. When the temperature inside the housing 1 decreases, the thermal expansion fluid stops expanding. At the same time, the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 move down to reset. When the output end of the first hydraulic telescopic rod 6 moves down, the rack 23 meshes with the gear 21 again, driving the cleaning plate 12 to reset and move, thus facilitating the cleaning of the heat sink 11 again. Simultaneously, as the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 reset and move down, the heat insulation plate 4 resets and moves down synchronously, thus facilitating the restoration to the initial state.

[0038] To facilitate the discharge of dust and other impurities to the outside of the housing 1, for example, such as Figure 4 , Figure 7 , Figure 8As shown, the present invention further includes a storage box 24 fixedly connected to the lower surface of the cover plate 3, a through hole 25 provided on the upper surface of the cover plate 3, the through hole 25 communicating with the interior of the storage box 24, a discharge port 26 provided on one side of the storage box 24, the discharge port 26 penetrating a partition, a horizontally arranged spiral feeding rod 27 provided inside the storage box 24, the end of the spiral feeding rod 27 away from the discharge port 26 passing through the storage box 24 and rotatably connected to the storage box 24, a one-way bearing 28 fixedly connected to the end of the spiral feeding rod 27 near the discharge port 26, a first pulley 29 fixedly connected to the one-way bearing 28, a second pulley 30 fixedly connected to the end of the first rotating shaft 14 near the first pulley 29, and the first pulley 29 and the second pulley 30 being driven by a transmission belt 31.

[0039] When in use, when the transmission belt 19 moves, it drives the cleaning plate 12 to move. When the cleaning plate 12 moves, it cleans both sides of the heat sink 11 by relying on the slot 13. When the cleaning plate 12 moves to a certain position, the cleaning plate 12 moves the dust and other impurities on the heat sink 11 into the through hole 25. At the same time, the dust and other impurities fall into the storage box 24, so as to facilitate the storage of the impurities cleaned on the heat sink 11. When the output end of the first hydraulic telescopic rod 6 moves upward, it drives the first rotating shaft 14 to rotate. When the first rotating shaft 14 rotates, it drives the first pulley 29 to rotate by the second pulley 30 and the transmission belt 31. At this time, the first pulley 29 cannot drive the spiral feeding rod 27 to rotate because the one-way bearing 28 is unable to drive the spiral feeding rod 27 to rotate. When the temperature inside the housing 1 decreases, the output end of the first hydraulic telescopic rod 6 resets and moves downward. The rack 23 and gear 21 drive the first rotating shaft 14 to rotate in the forward direction. When the first rotating shaft 14 rotates in the forward direction, the second pulley 30 and the transmission belt 31 drive the first pulley 29 to rotate. At this time, the first pulley 29 drives the spiral feeding rod 27 to rotate through the one-way bearing 28. When the spiral feeding rod 27 rotates, it conveys dust and other impurities in the storage box 24. With the rotation of the spiral feeding rod 27, the dust in the storage box 24 is output to the discharge port 26. The dust and other impurities are discharged to the outside of the housing 1 through the discharge port 26, thereby further improving the ease of use. The screw feed rod 27 can block the discharge port 26 to prevent garbage and other impurities from entering the storage box 24 through the discharge port 26; It should be noted that the bottom of the storage box 24 described in this invention is arc-shaped, which facilitates the cleaning of dust and other impurities inside the storage box 24 when the spiral cleaning rod rotates.

[0040] For example, such as Figure 1 As shown, the present invention also includes a plurality of sets of elastic protective nets 32 fixedly connected between the upper surface of the cover plate 3 and the lower surface of the heat insulation plate 4.

[0041] When in use, the elastic protective net 32 ​​can protect the space between the cover plate 3 and the heat insulation plate 4, preventing birds from entering the heat insulation plate 4 to build nests and thus creating safety hazards.

[0042] For example, such as Figure 1 As shown, the present invention also includes an inspection door 33 on the outside of the housing 1.

[0043] During use, the access port allows maintenance personnel to easily enter the enclosure 1 and inspect and maintain the components inside.

[0044] When in use, the present invention can improve the ease of installation of the prefabricated substation by relying on the base plate 2, the cover plate 3 and several sets of partitions, and at the same time facilitate the assembly of the box body 1. When the enclosure 1 is assembled and put into use, the components inside the enclosure 1 will generate heat during use. As the temperature inside the enclosure 1 rises, the heat inside the enclosure 1 is absorbed by the liquid storage tank 9 and the thermal expansion fluid. At the same time, the heat is transferred from the liquid storage tank 9 by the heat sink 11 and dissipated through the heat sink 11, thereby ensuring the safety of the components inside the enclosure 1. When the temperature inside the housing 1 is high, the heat sink 11 cannot meet the heat dissipation requirements. As the temperature inside the housing 1 rises, the thermal expansion fluid in the liquid storage tank 9 expands. The thermal expansion fluid enters the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 through the second connector 10, the pipeline, and the first connector 8, and drives the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 to extend. At the same time, it drives the heat insulation plate 4 to move upward. As the heat insulation plate 4 moves upward, the distance between the heat insulation plate 4 and the cover plate 3 increases, thereby improving the air circulation between the heat insulation plate 4 and the cover plate 3, and further improving the heat dissipation efficiency of the heat sink 11. When the output end of the first hydraulic telescopic rod 6 moves upward, it drives the rack 23 to move upward synchronously. The rack 23 meshes with the gear 21 and the transmission belt 19 drives the first rotating shaft 14 to rotate in the opposite direction. When the first rotating shaft 14 rotates in the opposite direction, the first pulley 17 and the transmission belt 19 drive the second pulley 18 to rotate in the opposite direction. When the transmission belt 19 moves, it drives the cleaning plate 12 to move. As the cleaning plate 12 moves, the slots 13 clean both sides of the heat sink 11, thereby ensuring the heat dissipation effect of the heat sink 11. When the cleaning plate 12 moves to a certain position, the cleaning plate 12 moves the dust and other impurities on the heat sink 11 into the through hole 25, and at the same time the dust and other impurities fall into the storage box 24, so as to facilitate the storage of the impurities cleaned on the heat sink 11. When the temperature inside the housing 1 decreases, the thermal expansion fluid stops expanding. At the same time, the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 move down to reset. When the output end of the first hydraulic telescopic rod 6 moves down, the rack 23 meshes with the gear 21 again and drives the cleaning plate 12 to reset and move, so as to facilitate cleaning the heat sink 11 again. At the same time, when the output end of the first hydraulic telescopic rod 6 is reset and moved down, the rack 23 and gear 21 drive the first rotating shaft 14 to rotate in the forward direction. When the first rotating shaft 14 rotates in the forward direction, the second pulley 30 and the transmission belt 31 drive the first pulley 29 to rotate. At this time, the first pulley 29 drives the spiral feeding rod 27 to rotate through the one-way bearing 28. When the spiral feeding rod 27 rotates, it conveys dust and other impurities in the storage box 24. With the rotation of the spiral feeding rod 27, the dust in the storage box 24 is output to the discharge port 26. The dust and other impurities are discharged to the outside of the box 1 through the discharge port 26, thereby further improving the ease of use. When the output ends of the first hydraulic telescopic rod 6 and the second hydraulic telescopic rod 7 are reset and moved downward, they drive the heat insulation plate 4 to reset and move downward simultaneously, so as to facilitate the restoration to the initial state.
