Description

Technical Field

[0001] The utility model belongs to the technical field of substations, in particular to an outdoor housing of a new type of box-type substation. Background Technique

[0002] The substation is an important part of the power transmission and distribution system. The box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device. The box-type substation has the characteristics of advanced technology, safe and reliable, high degree of automation and flexible combination mode. The box-type substation is mainly applicable to residential areas, urban public transformers, bustling downtown areas and other regions. The outdoor housing is an important part of the box-type substation.

[0003] Most of the existing outdoor housings of box-type substations assemble multiple side plates by bolts or rivets, and then install power transformation equipment inside the box. After installation, a box door will be reserved on the side wall of the box for later maintenance. However, when the power transformation equipment inside the box-type substation is damaged due to long-term use or improper use and needs to be replaced, at this time, due to the large volume of the power transformation equipment, it cannot be removed through the reserved box door on the box body. Therefore, it is necessary to remove the side plates of the box body again to expand the operation space. However, this installation method such as rivets or bolts will greatly affect the removal efficiency, and it cannot be used again after removal, thus causing waste of resources. Therefore, a new type of outdoor housing of box-type substation is urgently needed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide an outdoor housing of a new type of box-type substation to solve the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: An outdoor housing of a new type of box-type substation, including vertical plates and a bottom plate. The vertical plates are symmetrically and fixedly connected to the top surface of the bottom plate. A top plate is fixedly connected between the top surfaces of the two vertical plates. The top surface of the bottom plate is symmetrically provided with a plurality of convex grooves. The top surface of the bottom plate is symmetrically slidably connected with side plates for assembling the outdoor housing of the box-type substation. The lower end of the side plate is fixedly connected with a plurality of sliders, and the plurality of sliders are respectively slidably connected inside the plurality of convex grooves. The lower ends of the plurality of sliders are fixedly connected with rotating columns, and the rotating columns are slidably connected inside the convex grooves;

[0006] Both sides of the two vertical plates are provided with clamping grooves. One side of the inner wall of the clamping groove is provided with an installation hole. A spring is fixedly connected inside the installation hole. One side of the spring close to the clamping groove is fixedly connected with a plug block, and the plug block slidably extends into the clamping groove. One side of the plug block close to the spring is fixedly connected with a pull rod, and the pull rod slidably extends to the outside of the vertical plate. The side of the side plate close to the vertical plate is symmetrically and fixedly connected with clamping blocks, and a rectangular hole is opened on the side wall of the clamping block, and the rectangular hole matches the plug block.

[0007] Preferably, limiting grooves are symmetrically formed on the inner wall of the mounting hole, and limiting blocks are symmetrically and fixedly connected to the side wall of the insertion block.

[0008] Preferably, the two limiting blocks fixedly connected to the side wall of the insertion block are respectively slidably connected to the inside of the two limiting grooves formed on the inner wall of the mounting hole.

[0009] Preferably, cushion blocks are symmetrically and fixedly connected to the side of the side plate away from the vertical plate.

[0010] Preferably, a handle is fixedly connected to the side of the side plate close to the cushion block, and the handle is located at the middle part of the side plate.

[0014] Compared with the prior art, the technical effects and advantages of the present utility model:

[0015] For this new type of outdoor housing of the box-type substation, when it is necessary to replace the power conversion equipment inside the outdoor box-type substation, first pull outwards the pull rod that slides and extends outside the vertical plate, which simultaneously drives the insertion block to contract into the mounting hole and compress the spring until the insertion block moves out of the rectangular hole formed in the clamping block, thereby releasing the limitation on the clamping block and the side plate.

[0016] For this new type of outdoor housing of the box-type substation, pulling the side plate away from the vertical plate drives the slider fixedly connected to its lower end and the rotating column to slide along the convex groove. When the slider and the rotating column slide to the edge of the bottom plate along the convex groove, the rotating column will be limited by the convex groove at this time. Subsequently, the side plate can be flipped 180° away from the vertical plate, which can expand the operation space for the maintenance worker, thus facilitating the removal of the damaged power conversion equipment. Compared with the prior art, this device can effectively remove the side wall of the housing of the box-type substation, thereby increasing the operation space and facilitating the maintenance and disassembly of the power conversion equipment.

Specific embodiments

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0026] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, and are hereby explained together.

[0027] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0028] Such as Figures 1 to 5As shown, the main structure of the outdoor housing of a new type of box-type substation is the vertical plate 2 and the bottom plate 1. The vertical plates 2 are symmetrically and fixedly connected to the top surface of the bottom plate 1. A top plate 3 is fixedly connected between the top surfaces of the two vertical plates 2. A plurality of convex grooves 5 are symmetrically formed on the top surface of the bottom plate 1. The upper half of the convex groove 5 extends to the edge of the bottom plate 1, while the lower half does not extend to the edge of the bottom plate 1. Side plates 4 for assembling the housing of the outdoor box-type substation are symmetrically and slidably connected to the top surface of the bottom plate 1. A handle 15 is fixedly connected to the side of the side plate 4 close to the cushion block 14, and the handle 15 is located in the middle of the side plate 4;

[0029] A plurality of sliders 6 are fixedly connected to the lower end of the side plate 4, and the plurality of sliders 6 are respectively slidably connected inside the plurality of convex grooves 5. A rotating column 7 is fixedly connected to the lower end of the plurality of sliders 6, and the rotating column 7 is slidably connected inside the convex groove 5. When the slider 6 and the rotating column 7 move to the edge of the convex groove 5, the lower half of the convex groove 5 will block the rotating column 7, so that the slider 6 and the rotating column 7 will not move out of the convex groove 5. And because the upper half of the convex groove 5 extends to the edge of the bottom plate 1, the side plate 4 and the slider 6 can be flipped 180°, which is convenient for maintenance workers to disassemble and repair the power transformation equipment inside the box;

[0030] Clamping grooves 8 are formed on both sides of the two vertical plates 2. An installation hole 9 is formed on one side of the inner wall of the clamping groove 8. A spring 10 is fixedly connected inside the installation hole 9. A plug 11 is fixedly connected to the side of the spring 10 close to the clamping groove 8, and the plug 11 slidably extends into the clamping groove 8. Limiting grooves are symmetrically formed on the inner wall of the installation hole 9. Two limiting blocks 13 are symmetrically fixedly connected to the side wall of the plug 11. The two limiting blocks 13 fixedly connected to the side wall of the plug 11 are respectively slidably connected inside the two limiting grooves formed on the inner wall of the installation hole 9. Thanks to the fact that the limiting blocks 13 fixedly connected to the side wall of the plug 11 are slidably connected inside the two limiting grooves formed on the inner wall of the installation hole 9, the sliding direction of the plug 11 can be effectively limited;

[0031] A pull rod 12 is fixedly connected to the side of the plug 11 close to the spring 10, and the pull rod 12 slidably extends to the outside of the vertical plate 2. Clamping blocks 16 are symmetrically fixedly connected to the side of the side plate 4 close to the vertical plate 2. The preferred contact ends of the plurality of clamping blocks 16 and the plug 11 are all arc-shaped. A rectangular hole is formed on the side wall of the clamping block 16, and the rectangular hole matches the plug 11. When the clamping block 16 is inserted into the clamping groove 8 and contacts the plug 11, because the preferred contact end of the clamping block 16 and the plug 11 is arc-shaped, applying a thrust to the side plate 4 will cause the plug 11 to contract into the installation hole 9. When the plug 11 moves relatively to the rectangular hole formed on the side wall of the clamping block 16, the spring 10 will push the plug 11 to be inserted into the rectangular hole, so as to limit the clamping block 16 and the side plate 4.

[0032] On one side of the side plate 4 away from the vertical plate 2, there are symmetrically fixed connection pads 14. Thanks to the two pads 14 fixed on the side plate 4 contacting the ground and supporting the side plate 4, it also prevents the side plate 4 from rubbing against the ground and causing abrasions.

[0033] On one side of the side plate 4 close to the vertical plate 2, there is a fixed connection rectangular gasket 17, and the rectangular gasket 17 is hermetically attached to the side wall of the vertical plate 2. Thanks to the setting of the rectangular gasket 17, it can form a seal between the side plate 4 and the vertical plate 2, further preventing moisture or dust in the air from entering its interior.

[0034] Working principle

[0035] For this new type of outdoor housing of the box-type substation, during use, first, when it is necessary to replace the power transformation equipment inside the outdoor box-type substation, at this time, first pull outwards the pull rod 12 that slides and extends outside the vertical plate 2, and at the same time drive the plug 11 fixedly connected to the end of the pull rod 12 to contract into the installation hole 9 and compress the spring 10 fixedly connected inside the installation hole 9 until the plug 11 moves out of the inside of the rectangular hole opened on the side wall of the block 16 fixedly connected to the side wall of the side plate 4, thereby releasing the limit on the block 16 and the side plate 4. Subsequently, pull the handle 15, thereby driving the side plate 4 to be pulled towards the side away from the vertical plate 2, and at the same time drive the slider 6 fixedly connected to its lower end and the rotating column 7 fixedly connected to the lower end of the slider 6 to slide along the convex groove 5 opened on the top surface of the bottom plate 1. When the slider 6 and the rotating column 7 slide to the edge of the convex groove 5 on the bottom plate 1, at this time, the rotating column 7 will be limited by the convex groove 5, and then the side plate 4 can be flipped 180° towards the side away from the vertical plate 2. At this time, thanks to the two pads 14 fixedly connected to the side plate 4 contacting the ground and supporting the side plate 4, at this time, the operation space of the maintenance worker can be expanded, facilitating the removal of the damaged power transformation equipment. When the power transformation equipment is replaced, just reverse the above actions to install the side plate 4 again.
