Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a prefabricated substation that is easy to maintain. Background Technology

[0002] In power systems, prefabricated substations are an important type of power equipment, widely used in urban power grid construction, industrial and mining enterprises, and residential communities. However, traditional prefabricated substations face several problems in their design and operation that urgently need to be addressed.

[0003] On the one hand, maintenance difficulties are a prominent problem in traditional prefabricated substations. Due to their compact internal structure and limited space, maintenance often requires a significant amount of time and effort to disassemble and install various components, especially the removal and replacement of protective panels, which is extremely inconvenient. This not only increases the workload of maintenance personnel but may also lead to excessively long maintenance times, affecting the continuity of power supply. Moreover, during maintenance, the confined space makes it difficult for operators to maneuver, easily causing secondary damage to the equipment, further increasing maintenance costs and risks.

[0004] On the other hand, traditional prefabricated substations also have shortcomings in heat dissipation. With the continuous development of power equipment and the increase in power, prefabricated substations generate more and more heat during operation. If the heat cannot be dissipated in time, it will cause the internal temperature of the equipment to rise, affecting the performance and lifespan of the equipment, and may even lead to equipment failure and safety accidents. Traditional prefabricated substations are often not well designed for heat dissipation, with unreasonable layout and number of ventilation holes, which cannot meet the heat dissipation requirements of the equipment.

[0005] Therefore, developing a convenient prefabricated substation is of great practical significance. It can effectively solve the problems of traditional prefabricated substations in terms of maintenance, heat dissipation, and component replacement, and improve the performance and reliability of prefabricated substations. Utility Model Content

[0006] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the compact internal structure and limited space of prefabricated substations, which often require a lot of time and effort to disassemble and install various components during maintenance, especially the disassembly and replacement of protective plates, which is extremely inconvenient. Traditional prefabricated substations are often not perfect in terms of heat dissipation design, and the layout and number of heat dissipation holes are unreasonable, which cannot meet the heat dissipation needs of the equipment. Therefore, this utility model proposes a prefabricated substation that is easy to maintain.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A prefabricated substation that is easy to maintain, including a supporting base plate;

[0009] Support columns are fixedly installed at the top four corners of the support base plate;

[0010] The top plate is fixedly installed on the top of the four support columns;

[0011] The upper guard plate and the lower guard plate are respectively fixedly installed on the four sides of the bottom of the top plate and the four sides of the top of the supporting base plate;

[0012] The second guard plate is snapped between the support columns on both sides;

[0013] The first limiting component is disposed on one side of the upper guard plate and is used to limit the second guard plate;

[0014] A connecting plate that can be slidably connected between the lower guard plate and the upper guard plate on the front and back sides;

[0015] The door panel is hinged to one side of the two connecting plates that are close to each other;

[0016] The first guard plate is located on the side of the two connecting plates that are far apart from each other;

[0017] The second limiting component is disposed inside the upper and lower guard plates and is used to limit the first guard plate.

[0018] The first guard plate can be released by sliding the connecting plate after the door panel is removed, and the second guard plate can be removed by operating the first limit component after the first guard plate is removed, thus enabling four-sided maintenance.

[0019] In one possible design, the first limiting component includes:

[0020] A sliding vertical plate is slidably connected to the bottom of the upper guard plate;

[0021] A limiting groove is formed on one side of the sliding vertical plate;

[0022] An annular limiting protrusion is fixedly installed on the inner wall of the second guard plate and engages with the limiting groove.

[0023] One possible design also includes:

[0024] The limiting vertical rod can slide through the bottom inner wall of the upper guard plate and is located on both sides of the sliding vertical plate;

[0025] A pull plate is fixedly installed on the top of the two limiting vertical rods;

[0026] A tension spring connects the tension plate and the upper guard plate;

[0027] The upper pull plate can release the restriction on the sliding vertical plate.

[0028] In one possible design, the second limiting component includes:

[0029] The strip-shaped groove is formed inside the upper and lower protective plates;

[0030] A rectangular hole is formed on one side of the upper and lower protective plates and communicates with the strip groove;

[0031] A rectangular insert is fixedly installed on the top and bottom of the first protective plate and can be slidably embedded in the strip groove;

[0032] Pushing the first guard plate allows the rectangular insert to slide through the slot into the rectangular hole to complete the disassembly.

[0033] One possible design also includes:

[0034] Mounting plates are fixedly installed on both sides of the top of the support base plate to secure the lower guard plate.

[0035] In one possible design, the second protective plate has multiple second heat dissipation holes, and the first protective plate has multiple first heat dissipation holes, which are evenly distributed.

[0036] In this application, when the device needs maintenance, the two door panels can be opened by rotating the handle. After the door panels are opened, space is left for the two connecting plates to move laterally. At this time, the two connecting plates can be slid and brought closer to each other. The two connecting plates no longer abut against the first guard plate together with the support column. At this time, the first guard plate moves laterally, so that the rectangular insert slides from the inside of the slot to one side of the rectangular hole. Then the first guard plate is pushed out, and the rectangular insert moves out from the inside of the rectangular hole. The first guard plate can be cleaned or replaced.

[0037] Since the front and back sides of the device are identical, it can be disassembled using the method described above. When disassembling the second guard plates on both sides, the first guard plate must be disassembled first to make room for disassembling the second guard plates. The two pull plates can be lifted, which will move the two limiting vertical rods upward and stretch the tension springs. At this time, the two limiting vertical rods are no longer located on both sides of the two sliding vertical plates, and the limiting of the two sliding vertical plates is released. The two sliding vertical plates can be slid laterally, causing them to move away from each other. At this time, the limiting groove and the annular limiting protrusion are no longer engaged, thus releasing the braking state of the two second guard plates. The two second guard plates can then be cleaned or replaced. At the same time, space can be made available from all sides for the device, facilitating the maintenance of the transformer inside the device, increasing the working space, and making it convenient to use.

[0038] Beneficial Effects: This prefabricated substation offers a simple and efficient operation process for device maintenance. By rotating the door panel, lateral movement space is created for the connecting plates, allowing them to move closer together and releasing the obstruction on the first protective plate. This allows the first protective plate to be easily pushed out for cleaning or replacement. Since the front and rear sides of the device are identical, this method can be used to disassemble the first protective plate on both sides. When disassembling the second protective plates on both sides, first remove the first protective plate to create space, then lift the pull plate to move the limiting vertical rod upwards, releasing the restriction on the sliding vertical plates and allowing them to move away from each other, thus releasing the braking state on the second protective plate, allowing for cleaning or replacement. This design provides ample space from all sides, greatly facilitating the maintenance of the internal transformer, increasing workspace, and improving maintenance efficiency.

[0039] Both the first and second guard plates are easily disassembled and replaced. The first guard plate achieves positioning through the engagement of a rectangular insert with a slot and rectangular hole; disassembly is simple, requiring only a few steps to remove the rectangular insert. The second guard plate is fixed by the engagement of a limiting slot with an annular limiting protrusion and by the limiting vertical rod limiting the sliding vertical plate; disassembly also follows clear steps. This design allows for quick and flexible replacement of the guard plates when they are damaged or require periodic cleaning, ensuring the normal operation of the prefabricated substation.

[0040] The second protective plate has multiple second heat dissipation holes, and the first protective plate has multiple first heat dissipation holes. The arrangement of these heat dissipation holes helps the heat generated by the prefabricated substation during operation to dissipate in a timely manner, reduce the internal temperature of the equipment, avoid damage to the equipment due to excessive temperature, extend the service life of the equipment, and improve the stability and reliability of the equipment.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0047] In one embodiment: Refer to Figure 1-4 A prefabricated substation includes: a supporting base plate 1, which is made of rectangular steel plate, with four supporting columns 2, made of high-strength angle steel, fixedly installed at its four corners by welding. A rectangular top plate 3 is bolted to the top of the four supporting columns 2, with the edge of the top plate 3 extending beyond the outer edge of the supporting columns 2 to form a rain shelter. Four upper protective plates 6, rectangular in shape and located between adjacent supporting columns 2, are bolted to the four sides of the bottom of the top plate 3. Four lower protective plates 9 are bolted to corresponding positions on the four sides of the top of the supporting base plate 1, with the lower protective plates 9 parallel to the upper protective plates 6 and located inside the supporting columns 2.

[0048] Between the two support columns 2 located on both sides of the housing, two symmetrically arranged second protective plates 12 are engaged via a slot structure. The second protective plates 12 are made of galvanized steel, and their inner walls are fixedly fitted with annular limiting protrusions 19 by welding. At the bottom of the upper protective plate 6, two symmetrically arranged sliding vertical plates 21 are slidably connected via slide rails. The sliding vertical plates 21 are made of aluminum alloy profiles, and one side has a U-shaped limiting groove 20, which engages with the annular limiting protrusions 19 of the second protective plates 12. Two limiting vertical rods 18 slide through the bottom inner wall of the upper protective plate 6 via guide sleeves. The two limiting vertical rods 18 are located on the outer sides of the two sliding vertical plates 21, and their tops are fixedly fitted with the same pull plate 17 by welding. A tension spring 16 is installed between the pull plate 17 and the bottom inner wall of the upper protective plate 6, with both ends of the tension spring 16 hooked onto pre-set hanging holes on the pull plate 17 and the upper protective plate 6, respectively.

[0049] Between the lower guard plate 9 and the upper guard plate 6 on the front and back of the enclosure, two symmetrically arranged connecting plates 5 are slidably connected by guide rails. The connecting plates 5 are made of rectangular steel plates, and the side closer to each other is hinged to the door panel 4, with a handle installed on the outer surface of the door panel 4. The side of the connecting plates 5 furthest from each other is fixedly installed with bolts to the first guard plate 8, which is made of the same galvanized steel plate as the second guard plate 12. The upper guard plate 6 and the lower guard plate 9 have strip grooves 15 inside, and the ends of the strip grooves 15 connect to rectangular holes 14. Four rectangular inserts 13 are fixedly installed on the top and bottom of the first guard plate 8 by welding, and the rectangular inserts 13 form a sliding fit structure with the strip grooves 15 and the rectangular holes 14.

[0050] When maintenance is required, the operator opens both doors 4 by turning the handle on door 4. Once opened, doors 4 provide lateral movement space for the two connecting plates 5. The two connecting plates 5 are slid inwards along the guide rails until they are close to each other. At this point, the connecting plates 5 no longer collide with the first guard plate 8 along with the support column 2. The first guard plate 8 is then pushed laterally, causing the rectangular insert 13 at the top of the first guard plate 8 to slide along the slot 15 to the rectangular hole 14. Continuing to push, the rectangular insert 13 is completely removed from the rectangular hole 14, thus completing the disassembly of the first guard plate 8. Since the front and rear structures of the enclosure are identical, the first guard plate 8 can be disassembled using the same method.

[0051] When disassembling the second guard plates 12 on both sides, the first guard plate 8 at the corresponding position must be disassembled firstly as described above to leave room for operation. The operator lifts the two pull plates 17 upwards simultaneously with both hands. The pull plates 17 drive the limiting vertical rods 18 to move upwards along the guide sleeve and stretch the tension spring 16. When the limiting vertical rods 18 move out of both sides of the sliding vertical plate 21, the lateral limiting of the sliding vertical plate 21 is released. Push the two sliding vertical plates 21 laterally to move them away from each other. When the limiting groove 20 is completely separated from the annular limiting protrusion 19, the braking state of the second guard plate 12 is released. At this time, the second guard plate 12 can be pulled out of the slot for cleaning or replacement.

[0052] This structural design allows the enclosure to be opened from all four sides, enabling access to internal equipment such as transformers from four directions during maintenance, significantly increasing workspace. Both the first protective plate 8 and the second protective plate 12 are detachable, allowing for quick replacement without specialized tools, thus improving maintenance efficiency. The rational layout of the ventilation holes increases airflow within the enclosure, effectively reducing equipment operating temperature and extending equipment lifespan. The overall structure utilizes standardized interface design, ensuring high interchangeability of components and reducing future maintenance costs.

[0053] This application can be used in the field of power equipment, or in other fields applicable to this application.

[0054] In another embodiment: Reference Figure 1-4A convenient-to-maintain prefabricated substation is used in the field of power equipment. Multiple mounting plates 10 are bolted to both sides of the top of the supporting base plate 1. The mounting plates 10 are made of L-shaped angle steel, with their vertical surfaces connected to the supporting base plate 1 by bolts, and their horizontal surfaces used for mounting the lower protective plate 9. Multiple second heat dissipation holes 11 are evenly distributed on the second protective plate 12, and multiple first heat dissipation holes 7 are correspondingly distributed on the first protective plate 8.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
