Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically to a prefabricated substation that can be quickly inspected and repaired. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor / outdoor power distribution unit that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after traditional civil engineering substations. Prefabricated substations are suitable for 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] For example, the patent with the national authorized patent announcement number CN220585754U discloses a box-type substation that is easy to maintain. It includes a box body with a door on the front, ventilation slots on both side walls of the box body, and a first mounting plate installed on the top of the bottom plate of the box body through a front and rear sliding mechanism. The first mounting plate is used to install substation components. During maintenance, after the box door is opened, the first mounting plate can be moved outside the box body to increase the exposed space of the components, thereby allowing for better maintenance.

[0004] However, the aforementioned prefabricated substations that are easy to maintain have a risk of being blown away by the wind, accidentally bumped, or accidentally closed by their own weight, colliding with the moved equipment. This could easily injure maintenance personnel or damage the equipment, affecting maintenance efficiency. Furthermore, they lack an effective stabilizing structure during the sliding process. Utility Model Content

[0005] This utility model aims to solve the problems mentioned in the background art and provides a prefabricated substation that can be quickly inspected and maintained.

[0006] The specific technical solution is as follows: A prefabricated substation capable of rapid maintenance includes: a box body, a mating block installed on one side of the box door, a limit block installed on the side of the box base, a first threaded hole on the lower surface of the inner wall of the box, a maintenance assembly to be disassembled and installed inside the box, a mounting plate on the upper surface of the maintenance assembly, the mounting plate being used to install electrical equipment inside the substation, and the box door being able to be fixed by the cooperation of the limit block and the mating block when opened.

[0007] As a preferred embodiment of this utility model, the mating block is provided with a sliding hole, a spring is connected to the upper surface of the inner wall of the sliding hole, a limit plate is slidably installed in the sliding hole, and the lower surface of the spring is connected to one end of the surface of the limit plate.

[0008] As a preferred embodiment of this utility model, the upper surface of the limiting block is provided with a hole that matches the limiting plate, and the limiting block and the limiting plate are provided with the same insertion hole on one side. The insertion hole of the limiting block communicates with the hole, and a fixing rod is inserted into the insertion hole.

[0009] As a preferred embodiment of this utility model, the door can be fixed by pulling the limiting plate into the hole on the limiting block when it is opened for maintenance.

[0010] As a preferred embodiment of this utility model, the maintenance component includes a linear slide rail, which is provided in two sets and is respectively detachably installed on one end of the lower surface of the inner wall of the box. Positioning plates are respectively installed on the opposite side of the two sets of linear slide rails, and the upper surface of the positioning plate is provided with a second threaded hole that is the same as the lower surface of the inner wall of the box.

[0011] As a preferred embodiment of this utility model, a sliding plate is slidably installed inside the linear slide rail, and anti-detachment grooves are provided on both sides of the inner wall of the linear slide rail. Anti-detachment sliders are installed on both sides of the sliding plate, and the anti-detachment sliders are slidably installed in the anti-detachment grooves. The two sliding plates are respectively connected to the two ends of the lower surface of the mounting plate.

[0012] As a preferred embodiment of this utility model, one end of the upper surface of the sliding plate is provided with a receiving groove, one end of the receiving groove is rotatably mounted with a rotating shaft, one end of the rotating shaft is rotatably connected to a flip plate, the flip plate is L-shaped, the surface of the flip plate is provided with universal wheels, and the flip plate and the sliding plate are provided with the same third threaded hole on one side.

[0013] As a preferred embodiment of this utility model, two connecting plates are connected between the two linear slide rails. One of the connecting plates is equipped with a motor on one side, and the output shaft of the motor is connected to a screw. The other end of the screw is mounted on the other connecting plate via a bearing, and a connecting block is threaded onto the outer surface of the screw.

[0014] As a preferred embodiment of this utility model, the two sides of the connecting block are shaped as inclined plates, and each end of the screw is provided with a stabilizing rod. The two stabilizing rods are fixedly installed between the two connecting plates, and the inclined plates in the connecting block are slidably installed on the corresponding stabilizing rod side.

[0015] As a preferred embodiment of this utility model, the connecting block and the upper surface of the two inclined plates are all fixedly connected to one end of the lower surface of the mounting plate. When the sliding plate is moved out of the box, the flip plate flips from a horizontal storage state to a vertical state by rotating the rotating shaft, so that the universal wheel originally facing upwards rotates to the lower end, and the rotated universal wheel contacts the ground. The third threaded hole is threaded with a bolt.

[0016] This utility model has the following beneficial effects: 1. The prefabricated substation with rapid maintenance provided by this utility model, through the design of the box door, mating block, limit plate, and maintenance components, allows for easy maintenance by opening the box door, pulling the limit plate in the mating block to insert it into the limit block installed on the base, and then inserting the fixing rod through the insertion holes of the limit block and the limit plate to fix it, so that the box door is firmly locked in the open state, avoiding shaking caused by external forces. This allows the staff to carry out maintenance work stably, avoids shaking interference with operation, and improves the convenience of maintenance. The spring can quickly complete the reset. Then, the electrical equipment on the mounting plate can be moved out of the box through the maintenance components, eliminating the need to work in a small box, facilitating direct contact with the equipment for maintenance, and greatly reducing the difficulty of operation.

[0017] 2. The prefabricated substation with rapid maintenance provided by this utility model, through the design of linear slide rail, sliding plate, tilting plate, and screw, starts the motor and drives the screw to rotate, causing the connecting block to move along the screw axis. During the movement, the stabilizing rod can prevent the connecting block from shifting, ensuring that the mounting plate and the sliding plate below can be smoothly slid out of the box along the linear slide rail. The anti-detachment sliders on both sides of the sliding plate slide in the anti-detachment groove to prevent it from detaching from the linear slide rail. When one end of the sliding plate moves out of the box, the operator can rotate the tilting plate out of the receiving groove by rotating the shaft, so that the universal wheel turns downward and contacts the ground. By fixing the bolt in the third threaded hole, accidental rotation is avoided. Then, when moving out, the frictional resistance when the mounting plate is moved out as a whole is reduced, so that the equipment slides out smoothly. Attached Figure Description

[0024] Example 1 The prefabricated substation provided in this embodiment can be quickly inspected and repaired, such as... Figures 1-6 As shown, the enclosure includes: a housing 1; a mating block 201 is installed on one side of the door 101 on the housing 1; a limiting block 2 is installed on the side of the base 102 of the housing 1; a first threaded hole is provided on the lower surface of the inner wall of the housing 1; a maintenance assembly 4 is disassembled and installed inside the housing 1; a mounting plate 3 is provided on the upper surface of the maintenance assembly 4; the mounting plate 3 is used to install electrical equipment in the substation; the door 101 can be fixed by the limiting block 2 cooperating with the mating block 201 when opened. A sliding hole 205 is provided in the mating block 201; a spring 202 is connected to the upper surface of the inner wall of the sliding hole 205; a limiting plate 203 is slidably installed in the sliding hole 205; the lower surface of the spring 202 is connected to one end of the surface of the limiting plate 203. A hollow hole adapted to the limiting plate 203 is provided on the upper surface of the limiting block 2; both the limiting block 2 and the limiting plate 203 have the same insertion hole on one side; the insertion hole of the limiting block 2 communicates with the hollow hole; and a fixing rod 204 is inserted into the insertion hole. When the door 101 is opened for maintenance, it can be fixed by pulling the limiting plate 203 into the hole on the limiting block 2.

[0025] Through the design of the enclosure door 101, mating block 201, limiting plate 203, and maintenance component 4, during maintenance, the enclosure door 101 is opened, and the limiting plate 203 in the mating block 201 is pulled into the limiting block 2 installed on the base 102. Then, the insertion rod 204 is passed through the insertion hole of the limiting block 2 and the limiting plate 203 and fixed, so that the enclosure door 101 is firmly locked in the open state, avoiding shaking caused by external force. This allows the staff to carry out maintenance work stably, avoids shaking interference with operation, and improves maintenance convenience. The spring 202 can quickly complete the reset. Then, the electrical equipment on the mounting plate 3 can be moved out of the enclosure 1 through the maintenance component 4, eliminating the need to work in a small enclosure and facilitating direct contact with the equipment for maintenance, greatly reducing the difficulty of operation.

[0026] Example 2 The prefabricated substation provided in this embodiment can be quickly inspected and repaired, such as... Figures 3-6As shown, the maintenance component 4 includes a linear slide rail 401. Two sets of linear slide rails 401 are detachably installed on one end of the lower surface of the inner wall of the housing 1. Positioning plates 402 are installed on opposite sides of the two sets of linear slide rails 401. The upper surface of the positioning plates 402 has a second threaded hole identical to that on the lower surface of the inner wall of the housing 1. Sliding plates 409 are slidably installed inside the linear slide rails 401. Anti-detachment grooves 403 are provided on both sides of the inner wall of the linear slide rails 401. Anti-detachment sliders 410 are installed on both sides of the sliding plates 409, and the anti-detachment sliders 410 are slidably installed within the anti-detachment grooves 403. The two sliding plates 409 are respectively connected to both ends of the lower surface of the mounting plate 3. A receiving groove 411 is provided at one end of the upper surface of the sliding plate 409. A rotating shaft 412 is rotatably mounted at one end of the receiving groove 411. A flip plate 413 is rotatably connected to one end of the rotating shaft 412. The flip plate 413 is L-shaped and has universal wheels 414 on its surface. The flip plate 413 and the sliding plate 409 have the same third threaded hole on one side. Two connecting plates 405 are connected between the two linear slide rails 401. A motor 404 is provided on one side of one of the connecting plates 405. The output shaft of the motor 404 is connected to a screw 406. The other end of the screw 406 is mounted on one side of the other connecting plate 405 through a bearing. A connecting block 408 is threadedly connected to the outer surface of the screw 406. The two sides of the connecting block 408 are sloping plates. A stabilizing rod 407 is provided at each end of the screw 406. The two stabilizing rods 407 are fixedly installed between the two connecting plates 405. The sloping plates in the connecting block 408 are slidably installed on one side of the corresponding stabilizing rod 407. The connecting block 408 and the upper surface of the two inclined plates are fixedly connected to one end of the lower surface of the mounting plate 3. When the sliding plate 409 moves out of the box 1, the flip plate 413 flips from the horizontal storage state to the vertical state through the rotation of the rotating shaft 412, so that the universal wheel 414 originally facing upwards rotates to the lower end. After rotation, the universal wheel 414 contacts the ground, and the third threaded hole is threaded with a bolt.

[0027] Through the design of linear guide rail 401, sliding plate 409, tilting plate 413, and screw 406, the output shaft of starter motor 404 drives screw 406 to rotate, causing connecting block 408 to move axially along screw 406. During the movement, stabilizing rod 407 can prevent connecting block 408 from shifting, ensuring that the mounting plate 3 and the sliding plate 409 below can be smoothly driven to slide out of the housing 1 along linear guide rail 401. Anti-detachment sliders 410 on both sides of sliding plate 409 slide in anti-detachment groove 403 to prevent detachment from linear guide rail 401. When one end of sliding plate 409 moves out of housing 1, the operator can rotate the tilting plate 413 out of the receiving groove 411 by rotating shaft 412, so that caster wheel 414 turns downward and contacts the ground. By fixing bolt in the third threaded hole, accidental rotation is avoided. Then, when moving out, the frictional resistance when the mounting plate 3 is moved out as a whole can be reduced, so that the equipment slides out smoothly.

[0028] In summary, the prefabricated substation with rapid maintenance provided in this embodiment has the following advantages: through the cooperation of the locking block 201, the limiting plate 203, and the limiting block 2, the door 101 is securely locked in the open state, avoiding shaking caused by external forces, enabling the staff to carry out maintenance work stably, and improving stability during the sliding process, reducing shaking during movement and reducing friction when sliding out.

[0029] During use, open the enclosure door 101 during maintenance, pull the limiting plate 203 in the mating block 201 and insert it into the limiting block 2 installed on the base 102. Then, insert the fixing rod 204 through the insertion hole of the limiting block 2 and the limiting plate 203 to fix it, so that the enclosure door 101 is securely locked in the open state. Then, start the motor 404 and its output shaft drives the screw 406 to rotate, so that the connecting block 408 moves axially along the screw 406. During the movement, the stabilizing rod 407 can prevent the connecting block 408 from shifting, ensuring that the mounting plate 3 and the sliding below can be smoothly driven. The plate 409 slides out of the housing 1 along the linear slide rail 401. The anti-detachment sliders 410 on both sides of the sliding plate 409 slide in the anti-detachment groove 403 to prevent it from detaching from the linear slide rail 401. When one end of the sliding plate 409 moves out of the housing 1, the operator can rotate the rotating shaft 412 to make the flip plate 413 rotate out of the receiving groove 411, so that the caster wheel 414 turns downward and contacts the ground. By fixing the bolt in the third threaded hole, accidental rotation is avoided. Then, when it is moved out, the frictional resistance when the mounting plate 3 is moved out as a whole can be reduced, so that the mounting plate 3 slides out smoothly.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
