[0001] This utility model relates to the field of transformer substation housing technology, specifically a modular transformer substation housing. Background Technology

[0002] A prefabricated transformer substation enclosure is a special type of equipment housing used in power systems. It typically consists of a base, top cover, front panel, back panel, and side panels.

[0003] A search revealed patent CN218216249U, which describes a modular transformer substation enclosure. The enclosure includes a housing and two doors rotatably mounted on the housing. Each door has a fixed ventilation window. Each door has a rotatably mounted roller, and dustproof nets are fixedly connected to the circumference of each roller. Each door has a locking component to restrict the sliding of the dustproof nets. Each door also has a cleaning component for cleaning the dustproof nets. By utilizing the dustproof nets and the cleaning components to remove dust from the nets, the enclosure not only blocks external dust but also removes dust adhering to the nets, thus improving the protection of the internal substation.

[0004] Although the dust filter of the current transformer substation can be cleaned, it can only be cleaned manually. If it is not cleaned in time, dust and impurities will continue to accumulate, which will aggravate the heat dissipation problem of the equipment, affect the normal operation and life of the equipment, and there is also the problem of low cleaning efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a modular transformer substation housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular transformer substation housing, comprising a housing, a top cover fixedly installed on the top of the housing, a top cover hinged to one side of the housing, two top covers symmetrically arranged, heat dissipation plates provided on the side walls of the two top covers, heat dissipation holes evenly opened on the side walls of the two heat dissipation plates, and a cleaning component provided on one side of the two heat dissipation plates.

[0007] The cleaning component includes a mounting plate disposed on one side of the heat sink. The mounting plates are evenly distributed, and each mounting plate has multiple brush bristles inside. Each brush bristle is fixedly connected by a connecting plate. Both ends of each mounting plate are fixedly connected by a fixing plate. Both fixing plates are slidably installed inside the door. A slider is fixedly installed on the side wall of one of the fixing plates. A cam is provided at the bottom end of the slider. A rotating shaft is fixedly installed inside the cam. A motor is provided at the end of the rotating shaft away from the cam. The motor is located inside the door.

[0008] As a further preferred embodiment of this technical solution, the slider is slidably installed inside the door, and a spring is installed between the slider and the heat sink.

[0009] As a further preferred embodiment of this technical solution, each mounting plate is provided with two connecting plates inside, and the two connecting plates are symmetrically distributed.

[0010] As a further preferred embodiment of this technical solution, the connecting plate is slidably installed inside the mounting plate, and a first tension spring is provided between the connecting plate and the mounting plate.

[0011] As a further preferred embodiment of this technical solution, the heat sink is mounted on the side wall of the cabinet door by connecting bolts, and an auxiliary cleaning component is provided inside the cabinet door.

[0012] As a further preferred embodiment of this technical solution, the side wall of the cabinet door is provided with a through groove, which is located at the bottom end of the heat dissipation plate.

[0013] As a further preferred embodiment of this technical solution, the fixed plate auxiliary cleaning assembly includes a push plate disposed inside the box door, the push plate being slidably connected to the box door, a second tension spring being installed between the push plate and the box door, a wedge being fixedly connected to the side wall of the push plate, a moving rod being disposed at the top of the wedge, and the moving rod being fixedly installed at the bottom end of the fixed plate.

[0014] This utility model provides a modular transformer substation housing, which has the following advantages:

[0015] (1) By setting up the cleaning component, when the heat sink needs to be cleaned, the PLC controls the motor to start. The start of the motor drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the rotation of the cam, the rotation of the cam drives the slider to move upward, the movement of the slider drives the movement of the fixed plate, the movement of the fixed plate drives the movement of the mounting plate, and the movement of the mounting plate drives the movement of the brush, so that the brush cleans the heat sink and heat dissipation holes. This avoids the problem that although the current transformer substation housing can clean the dust screen, it can only be cleaned manually. If the cleaning is not timely, dust and impurities will continue to accumulate, which will aggravate the heat dissipation problem of the equipment, affect the normal operation and life of the equipment, and there is also the problem of low cleaning efficiency. This invention improves the cleaning efficiency and indirectly improves the heat dissipation effect of the assembled transformer substation housing.

[0016] (2) By setting up the auxiliary cleaning component, when the mounting plate moves downward, the movement of the mounting plate drives the movement of the moving rod. After the bottom end of the moving rod contacts the wedge, it drives the wedge to move outward. The movement of the wedge drives the movement of the push plate, which pushes the impurities inside the through groove and pushes them outward, thereby improving the cleanliness of the inside of the box door.

Second tension spring. Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figures 1 to 6 As shown, in this embodiment, a modular transformer housing includes a housing 1, a top cover 2 is fixedly installed on the top of the housing 1, a top cover 2 is hinged to one side of the housing 1, two top covers 2 are symmetrically arranged, a heat dissipation plate 4 is provided on the side wall of both top covers 2, heat dissipation holes 5 are evenly opened on the side wall of both heat dissipation plates 4, and a cleaning component is provided on one side of both heat dissipation plates 4.

[0026] The cleaning component includes a mounting plate 8 disposed on one side of the heat sink 4. The mounting plates 8 are evenly distributed, and each mounting plate 8 has multiple bristles 9 inside. Each bristle 9 is fixedly connected by a connecting plate 10. Both ends of each mounting plate 8 are fixedly connected by a fixing plate 12. Both fixing plates 12 are slidably installed inside the door 3. A slider 13 is fixedly installed on the side wall of one of the fixing plates 12. A cam 17 is provided at the bottom end of the slider 13. A rotating shaft 16 is fixedly installed inside the cam 17. A motor 15 is provided at the end of the rotating shaft 16 away from the cam 17. The motor 15 is located inside the door 3.

[0027] The heat dissipation hole 5 is set downward to minimize the possibility of external rainwater entering the enclosure 1 through the heat dissipation hole 5 when the transformer enclosure is used outdoors.

[0028] When cleaning the heat sink 4, the motor 15 can be controlled to start at regular intervals to ensure that the heat sink 4 is cleaned in a timely manner.

[0029] By configuring the cleaning components, when cleaning of the heat sink 4 is required, the PLC controls the motor 15 to start. The start of the motor 15 drives the rotation of the rotating shaft 16, which in turn drives the rotation of the cam 17. The rotation of the cam 17 causes the slider 13 to move upward, which in turn moves the fixed plate 12. The movement of the fixed plate 12 then moves the mounting plate 8, which in turn moves the brush 9. This allows the brush 9 to clean the heat sink 4 and the heat dissipation holes 5. This avoids the problem that, although the current transformer substation housing can clean the dust filter, it can only be done manually. If cleaning is not timely, dust and impurities will accumulate, which will aggravate the heat dissipation problem of the equipment, affect the normal operation and lifespan of the equipment, and also result in low cleaning efficiency. This improves the cleaning efficiency and indirectly improves the heat dissipation effect of the assembled transformer substation housing.

[0030] like Figures 1 to 6 As shown, slider 13 is slidably installed inside the door 3, and spring 14 is installed between slider 13 and heat sink 4.

[0031] When the slider 13 slides inside the door 3, it causes the spring 14 to deform and store elastic potential energy. The release of this elastic potential energy, combined with the rotation of the cam 17, causes the slider 13 to move up and down repeatedly, thereby causing each set of brush bristles 9 to move up and down repeatedly to clean the heat dissipation plate 4 and the heat dissipation holes 5, further improving the cleaning effect of the device.

[0032] like Figures 1 to 6 As shown, each mounting plate 8 has two connecting plates 10 inside, and the two connecting plates 10 are symmetrically distributed.

[0033] The inner wall of the box door 3 away from the heat dissipation plate 4 is also evenly provided with heat dissipation holes 5. The mounting plate 8 is located between the two sets of heat dissipation holes 5, and the two connecting plates 10 are symmetrically distributed. When the mounting plate 8 moves, it can clean the heat dissipation holes 5 on the side wall of the heat dissipation plate 4 and the heat dissipation holes 5 inside the box door 3, thereby improving the comprehensiveness of the cleaning of the device.

[0034] like Figures 1 to 6 As shown, the connecting plate 10 is slidably installed inside the mounting plate 8, and a first tension spring 11 is provided between the connecting plate 10 and the mounting plate 8.

[0035] When the mounting plate 8 moves the brush bristles 9 to one side of the heat dissipation hole 5, the elastic potential energy of the first tension spring 11 drives the brush bristles 9 to slide to one side of the heat dissipation hole 5, making it easier for the brush bristles 9 to embed into the interior of the heat dissipation hole 5 and clean the interior of the heat dissipation hole 5.

[0036] like Figures 1 to 6 As shown, the heat sink 4 is installed on the side wall of the door 3 by connecting bolts 6, and the interior of the door 3 is equipped with an auxiliary cleaning component.

[0037] This allows for the removal of the heat sink 4 to facilitate maintenance of the interior of the cabinet door 3.

[0038] like Figures 1 to 6 As shown, a through groove 7 is provided on the side wall of the door 3, and the through groove 7 is located at the bottom of the heat dissipation plate 4.

[0039] The channel 7 is inclined. When the brush 9 cleans the side wall of the heat sink 4, some dust and impurities may be carried into the door 3 by the brush 9. These impurities fall to the bottom and are discharged from the channel 7.

[0040] like Figures 1 to 6 As shown, the auxiliary cleaning assembly of the fixed plate 12 includes a push plate 20 disposed inside the box door 3. The push plate 20 is slidably connected to the box door 3. A second tension spring 21 is installed between the push plate 20 and the box door 3. A wedge block 19 is fixedly connected to the side wall of the push plate 20. A moving rod 18 is provided at the top of the wedge block 19. The moving rod 18 is fixedly installed at the bottom of the fixed plate 12.

[0041] With the auxiliary cleaning component in place, when the mounting plate 8 moves downward, the movement of the mounting plate 8 drives the movement of the moving rod 18. After the bottom end of the moving rod 18 contacts the wedge 19, it drives the wedge 19 to move outward. The movement of the wedge 19 drives the movement of the push plate 20, which pushes the impurities inside the through groove 7 outward, thereby improving the cleanliness of the inside of the door 3.

[0042] When the moving rod 18 moves downward and the wedge block 19 moves, the wedge block 19 drives the push plate 20 to move, causing the second tension spring 21 to deform and store elastic potential energy. When the moving rod 18 moves upward, the elastic potential energy is released through the second tension spring 21, causing the push plate 20 to reset.

[0043] This utility model provides a modular transformer substation housing, the specific working principle of which is as follows:

[0044] When the heat sink 4 needs to be cleaned, the motor 15 is started by the PLC control. The start of the motor 15 drives the rotation of the rotating shaft 16, which in turn drives the rotation of the cam 17. The rotation of the cam 17 drives the slider 13 to move upward. The movement of the slider 13 causes the spring 14 to deform and store elastic potential energy. The spring 14 releases its elastic potential energy and, in conjunction with the rotation of the cam 17, causes the slider 13 to move up and down repeatedly. The movement of the slider 13 drives the fixed plate 12 to move, which in turn drives the mounting plate 8 to move. The movement of the mounting plate 8 drives the brush bristles 9 to move. When the mounting plate 8 moves the brush bristles 9 to one side of the heat dissipation hole 5, the elastic potential energy of the first tension spring 11 drives the brush bristles 9 to slide towards one side of the heat dissipation hole 5, so that the brush bristles 9 are embedded in the interior of the heat dissipation hole 5 to clean the interior of the heat dissipation hole 5. The cleaned impurities fall to the bottom.

[0045] When the mounting plate 8 moves downward, the movement of the mounting plate 8 drives the movement of the moving rod 18. After the bottom end of the moving rod 18 contacts the wedge block 19, it drives the wedge block 19 to move outward. The movement of the wedge block 19 drives the movement of the push plate 20, which pushes the impurities inside the through groove 7 and pushes them outward.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
