Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to a box-type substation that is convenient for maintenance. Background Art

[0002] A box-type substation, also called a prefabricated substation or a prefabricated transformer substation, is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device. It is a factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme, that is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, mouse-proof, fire-proof, anti-theft, heat-insulating, fully enclosed steel structure box. It is especially suitable for urban network construction and transformation and is a brand-new substation that emerged after civil substations.

[0003] Box-type substations are applicable to mines, factories and enterprises, oil and gas fields, and wind power stations. They replace the original civil power distribution rooms and substations and become new types of complete sets of power transformation and distribution devices. In order to ensure the normal power supply of factories and enterprises, the staff needs to regularly overhaul the substation to eliminate faults and ensure normal production. When a fault occurs in the factory circuit, it needs to be repaired in a timely and rapid manner to ensure normal operation.

[0004] The box doors of existing box-type substations usually open from the side. When the staff maintains on both sides of the box-type substation, it is easy to hit the box door, and it cannot play a sunshade role when maintaining under the scorching sun, which has deficiencies. Summary of the Invention

[0005] The purpose of the present invention is to solve the above technical problems and provide a box-type substation that is convenient for maintenance.

[0006] The technical solution of the present invention is as follows: A box-type substation that is convenient for maintenance, comprising: A cover plate, which is provided with a through groove; A box body, which has openings on both sides, and each opening is rotatably connected with a cover plate; A slide plate, which has a rack and is installed on the cover plate and can slide up and down along the cover plate; A gear, which is rotatably arranged in the through groove and meshes with the rack on the slide plate; Two first magnets, which are arranged at intervals on the cover plate; Two second magnets, which are arranged at intervals on the slide plate, and the position of the slide plate is adjusted by the attraction of the second magnets at different positions to the first magnets; Two moving plates, which are slidably arranged on the cover plate, and each moving plate is provided with a rack on one side; A traction device, which connects the moving plate and the cover plate; A sealing frame, slidably arranged in the box body, can be driven to move by a first driving device.

[0007] In a possible technical solution, the cover plate includes: A first chute, slidably connected to the sliding plate; A jack, communicating with the first chute; A plug rod, arranged at the bottom of the sliding plate and adapted to the jack; The box body further includes: Second chutes, opened on both sides of the inner wall of the box body; Slide rods, opened on both sides of the sealing frame, and the slide rods can slide in the second chutes, facilitating reliable connection and disassembly with the cover plate.

[0008] In a possible technical solution, the weights of the two moving plates are different; The box-type substation further includes: A dehumidification device, arranged on the box body, for drying the air flowing into the box body. The dehumidification device includes: A first protective box, arranged on the box body, and the first protective box is provided with through holes; A humidity sensor, arranged in the first protective box; A controller, arranged in the box body and connected to the humidity sensor; An electric heating element, arranged in the box body and electrically connected to the controller; A storage box, connected to the first pull rope, and activated carbon is stored in the storage box, protecting electrical components while extending the service life of the equipment, improving the operation reliability of the equipment in the box-type substation, and preventing condensation and corrosion.

[0009] In a possible technical solution, it further includes a second driving device, and the second driving device includes: An electromagnet, arranged on the cover plate; A fifth magnet, arranged on the moving plate, for driving any one of the moving plates to move downward relative to the cover plate.

[0010] In a possible technical solution, the box-type substation further includes: Two second protective boxes, correspondingly arranged on the cover plate, and each second protective box has an opening on its upper surface; A protective plate, arranged on both sides of the upper surface of the first protective box, for extending the service life of the substation; Two guiding devices, and each guiding device includes: An inclined rod, arranged on the box body; The guide wheel is rotatably arranged on the inclined rod to improve the smoothness of the side cover plate of the box-type substation switch and reduce mechanical wear.

[0011] In a possible technical solution, the traction device includes: A first pulling rope connecting the two moving plates; A second pulling rope connecting the moving plate and the cover plate, which is convenient and fast for maintenance.

[0012] The beneficial effects of the present invention are as follows: By pulling the first pulling rope or the second pulling rope, the position of the moving plate on the cover plate changes, and then the cover plate is opened or closed on the box body, which is convenient for the maintenance of the box-type substation. Moreover, after the cover plate is opened, it can play a sunshade role. Specifically, it is reflected in: The moving plate moves upward under the action of the pulling force, contacts the gear and drives it to rotate. The rotation of the gear drives the sliding plate to move downward. The second magnet on the top of the sliding plate is separated from the first magnet above the cover plate. The second magnet attracts the first magnet, fixes the sliding plate and then fixes the moving plate to prevent it from sliding downward on the cover plate. Moreover, the third magnet and the fourth magnet are separated, and the spring gives a pulling force to the top of the sealing frame to make it move into the box body. Since the weight of the top of the cover plate is greater than that of the bottom and the inner side is greater than the outer side, the opening of the box body is opened, and the staff can maintain the inside of the box-type substation. At the same time, the cover plate can also play a role in shading the sun.

[0013] After the inside of the box-type substation is maintained, pull the second pulling rope to make the cover plate rotate in the reverse direction and return to the vertical position. Pull the moving plate downward to make it move downward. The moving plate drives the gear to rotate, and the rotation of the gear drives the sliding plate to move upward. The second magnet attracts the first magnet to fix the sliding plate. At the same time, the third magnet gives a suction force to the fourth magnet to drive the sealing frame to move and seal the contact part between the box body and the cover plate.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1 Referring to Figures 1 to 12 As shown, this embodiment provides a box-type substation convenient for maintenance, including: A box body 10 with openings on both sides and two cover plates 2. An air inlet groove 101 is provided on the box body 10. Round rods 201 are provided on both sides near the top of the cover plate 2. The cover plate 2 is rotatably arranged on the box body 10 through the two round rods 201. The cover plate 2 is further provided with a sliding plate 202 with a rack, a gear 203, a through groove 204 and two spaced-apart first magnets 205. The sliding plate 202 is slidably arranged on the cover plate 2. Two second magnets 2021 are arranged at intervals on the sliding plate 202. The gear 203 is rotatably arranged in the through groove 204 and meshes with the rack on the sliding plate 202; Further included are: Two moving plates 3 each provided with a rack on one side are slidably arranged on the cover plate 2; A traction device, the traction device includes a first pulling rope 4 and two second pulling ropes 5. The first pulling rope 4 connects the two moving plates 3, one end of which is connected to the bottom of the moving plate 3 and the other end passes through the cover plate 2; A sealing frame 6 provided with a sealing gasket on one side is slidably arranged in the box body 10; Two first driving devices, which include a third magnet 7, a spring 8, a fourth magnet 9 and a connecting block 11. The third magnet 7 is arranged on the sliding plate 202, the fourth magnet 9 is arranged on the sealing frame 6, the connecting block 11 is arranged on the inner wall of the box body 10, and the spring 8 connects the sealing frame 6 and the connecting block 11. In the present invention, when internal maintenance of the box-type substation is required, by pulling the first pulling rope 4 on one side, the moving plate 3 on the other side moves upward under the action of the pulling force and contacts the gear 203 to drive it to rotate. The rotation of the gear 203 drives the sliding plate 202 to move downward. The second magnet 2021 on the top of the sliding plate 202 is separated from the first magnet 205 above the cover plate 2, and the second magnet 2021 on the bottom of the sliding plate 202 attracts the first magnet 205 below the cover plate 2 to fix the sliding plate 202 and further fix the moving plate 3 to prevent it from sliding downward on the cover plate 2. And the third magnet 7 is separated from the fourth magnet 9, and the spring 8 gives a pulling force to the top of the sealing frame 6 to make it move into the box body 10. Since the weight of the top of the cover plate 2 is greater than that of the bottom and the inner side is greater than the outer side, the cover plate 2 rotates through the round rod 201 until one side of the cover plate 2 abuts against the wall body at the opening of the box body 10, thereby opening the opening of the box body 10. The staff can perform internal maintenance on the box-type substation. At the same time, the cover plate 2 can also play a role in blocking the sun. When the internal maintenance of the box-type substation is completed, pull down the second pulling rope 5 to make the cover plate 2 rotate in the reverse direction and return to the vertical position, and then pull down the moving plate 3 to make it move downward. The moving plate 3 drives the gear 203 to rotate, and the rotation of the gear 203 drives the sliding plate 202 to move upward. The second magnet 2021 on the top of the sliding plate 202 attracts the first magnet 205 above the cover plate 2 to fix the sliding plate 202. At the same time, the third magnet 7 attracts the fourth magnet 9 to drive the sealing frame 6 to move. The side of the sealing frame 6 provided with the sealing gasket closely abuts against one side of the cover plate 2, thereby sealing the contact part between the box body 10 and the cover plate 2. Specifically, four T-shaped rods are arranged on one side of the moving plate 3, and two third chutes adapted to the T-shaped rods are arranged on the cover plate 2; one end of the second pulling rope 5 passes through the cover plate 2 and is wound in the box body 10; the tops of the cover plate 2, the bottom and the top of the sliding plate 202 are all arc-shaped to prevent interference during the rotation of the cover plate 2; It should be noted that in this embodiment, a first sliding groove 206 and a jack 207 communicating therewith are provided on the cover plate 2. The sliding plate 202 can slide in the first sliding groove 206. A plug rod 2022 adapted to the jack 207 is provided at the bottom of the sliding plate 202. The plug rod 2022 is adapted to the jack 207 to prevent the sliding plate 202 from falling off the first sliding groove 206.

[0018] It should be noted that in this embodiment, second sliding grooves 102 are provided on the inner walls of both sides of the box body 10. Slide rods 601 are provided on both sides of the sealing frame 6. One end of the slide rod 601 can slide in the second sliding groove 102. The slide rod 601 is adapted to the second sliding groove 102 to enable the sealing frame 6 to move horizontally back and forth in the box body 10.

[0019] It should be noted that In this embodiment, second protection boxes 208 with open tops are provided on both of the cover plates 2. Two cover plates 2081 are detachably provided on the top of the second protection box 208. A semi-circular hole is provided on one side of the cover plate 2081. Specifically, the left moving plate 3 abuts against the cover plate 2081, and the right moving plate 3 abuts against the inner wall of the second protection box 208. The cover plate 2081 is connected to the second protection box 208 by bolts. The second protection box 208 and the cover plate 2081 can prevent external personnel from randomly pulling the first pull rope 4; the semi-circular holes on the two cover plates 2081 combine to form a circular hole for the first pull rope 4 to pass through.

[0020] In this embodiment, the second driving device includes an electromagnet 19 and a fifth magnet 20. The electromagnet 19 is provided on the cover plate 2, and the fifth magnet 20 is provided on the moving plate 3. The electromagnet 19 is electrically connected to the controller 16.

[0025] It should be noted that there is also a second driving device, and the second driving device includes: An electromagnet 19, which is arranged on the cover plate 2. A fifth magnet 20, which is arranged on the moving plate 3 and is used to drive any one of the moving plates 3 to move downward relative to the cover plate 2.

[0026] It should be noted that the present embodiment further includes a first time relay 14 and a second time relay 15. The first time relay 14 and the second time relay 15 are both arranged in the box 10, and the first time relay 14 and the second time relay 15 are both connected to the controller 16, the first time relay 14 is connected to the two electric heating elements 17 and the second drive device, and is used to link the electric heating elements and the second drive device to work, and the second time relay 15 is connected to the second drive device, and is used to link the second drive device to stop working.

[0027] It should be noted that the first pull rope 4 passes through the first protective box 12 and is connected to the two storage boxes 18. The storage boxes 18 are provided with grid holes on one side and the bottom. The second driving device is used to drive one of the movable plates 3 to move downward relative to one of the cover plates 2. Specifically, the weight of the movable plate 3 on the right is greater than that of the movable plate 3 on the left. When the humidity of the air in the box 10 is greater than the preset value of the humidity sensor 13, a signal is sent to the controller 16. The controller 16 controls the first time relay 14, the two electric heating elements 17 and the second driving device to work. The second driving device works to drive the movable plate 3 on the left to move downward and then drives the first pull rope 4 to move. The first pull rope 4 drives the movable plate 3 on the right to move upward. The movement of the first pull rope 4 drives the two storage boxes 18 to move. The storage box 18 on the left moves to above the electric heating element 17 on the left. The electric heating element 17 works to dry the activated carbon in the storage box 18.
