Description

Technical Field

[0001] The present invention relates to the technical field of transformer substation inspection, and in particular to a transformer substation hanging cabinet type inspection system. Background Art

[0002] Electricity plays a vital role in the development of the national economy. As the power industry rapidly develops toward larger units, larger capacities, and higher voltages, ensuring the safe operation of power supply systems and the constant stability and good condition of power equipment have become prominent issues in power management. Substations are the core of the entire power grid, playing a crucial role in dispatching power. Therefore, substation inspections are particularly important.

[0003] Current inspection methods include traditional inspection and intelligent inspection. Traditional inspection remains the predominant method for substation inspections in my country, but it suffers from numerous drawbacks, including the inability to ensure on-site inspection personnel arrive and operate according to pre-determined standards, limited information storage in tables, and a lack of on-site access to detailed inspection standards and operating procedures for each substation's specific equipment. To automate and streamline substation equipment inspections, reduce staff workload, and improve work quality, the demand for intelligent inspection systems is urgent. Intelligent inspection has gradually replaced traditional inspections.

[0004] However, the current inspection method is mostly to operate the inspection camera to conduct mobile inspections at a certain height or to fix it in a position for sentry inspections. Due to the complex inspection environment, the inspection camera is exposed for a long time, causing dust accumulation, and lacks protection and cannot be stored. To a certain extent, it accelerates its damage and aging. In response to this, we designed a substation cabinet inspection system. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a substation cabinet type inspection system.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A substation cabinet-type inspection device comprises a cabinet body and an inspection camera, wherein the inspection camera is installed inside the cabinet body, a mounting bracket is fixed on the top of the cabinet body, and a mounting bracket is fixed on the top of the cabinet body, wherein the mounting bracket can be fixedly suspended on a wall or the mounting bracket can be installed on a track for electrically driven sliding, so as to move horizontally for large-scale inspection, and the cabinet body is in the shape of an inverted U-shaped structure, and slots are provided at positions near the openings at both ends of the top of the cabinet body, partitions are inserted in the slots, and first racks are fixed on both sides of the inner wall of the partition, and the first racks are fixed to the lower part of the outer wall of the partition, the inner wall of the cabinet body is rotatably provided with a gear meshing with the first rack, and the inner wall of the cabinet body is installed with a pushing mechanism driven by an electric push rod;

[0008] The pushing mechanism includes a mounting plate, the inner wall of the cabinet is slidingly provided with a second rack meshing with the gear, the outer wall of the second rack is fixed with a connecting rod, the connecting rod is fixed to the outer wall of the mounting plate, the inspection camera is fixed to the bottom of the mounting plate, and the substation is inspected by the inspection camera located inside the cabinet. During operation, the electric push rod drives the mounting plate to move downward, and the inspection camera is synchronously moved downward. When moving downward, the second rack connected to the connecting rod moves downward. Due to the downward movement of the second rack, the gear meshing with it rotates clockwise, thereby realizing the upward movement of the first rack meshing with the gear, so that the partition moves up, and the partitions located at both ends of the cabinet move up, so that both ends of the cabinet are opened, so that the inspection camera that moves downward is exposed and works.

[0009] Cleaning members are installed at both ends of the inner wall of the cabinet near the partition, and the cleaning members are connected to the gear through a transmission mechanism. The cleaning members are used to clean the lens of the inspection camera. The electric push rod drives the mounting plate to move downward, and the arranged inspection camera moves downward synchronously. When moving downward, the second rack connected to the connecting rod moves downward. Due to the downward movement of the second rack, the gear engaged with it rotates clockwise, thereby realizing the upward movement of the first rack engaged with the gear, so that the partition moves up, and the partitions located at both ends of the cabinet move up, so that the two ends of the cabinet are opened, so that the inspection camera that moves down is exposed and works. In the process of moving downward, due to the rotation of the gear, the first synchronous wheel rotates, and the second synchronous wheel rotates through the synchronous belt, thereby realizing the rotation of the rotating rod, so that the cleaning sleeve on the rotating rod cleans the lens of the inspection camera, and then the inspection can be carried out freely. Similarly, when the inspection camera is not used for inspection, the inspection camera can be driven to move up by the electric push rod, and the gear rotates counterclockwise. Similarly, the partition moves down, and the rotating rod rotates synchronously, and the lens of the inspection camera that needs to be stored is cleaned again.

[0010] As a further solution of the present invention, the top of the electric push rod is fixed to the top of the inner wall of the cabinet, and the output end of the electric push rod is fixed to the top of the mounting plate.

[0011] As a further solution of the present invention, an engaging groove is provided at one end of the connecting rod close to the mounting plate, and the engaging groove is engaged with the outer wall of the mounting plate. The connecting rod is fixed to the mounting plate by bolts, so that the connecting rod can be installed and disassembled for replacement and maintenance.

[0012] As a further solution of the present invention, a first limiting groove is provided on the outer wall of the first rack, and a second limiting strip corresponding to the first limiting groove is fixed on the inner wall of the cabinet. The first limiting groove is slidably arranged in the second limiting strip to ensure that when the electric push rod moves the mounting plate, the moving first rack can move more stably under the action of the second limiting strip.

[0013] As a further solution of the present invention, a second limiting groove is provided on the outer wall of the second rack, and a first limiting strip corresponding to the second limiting groove is fixed on the inner wall of the cabinet. The second limiting strip is slidably arranged in the first limiting strip to ensure that when the electric push rod moves the mounting plate, the moving second rack can move more stably under the action of the first limiting strip.

[0014] As a further solution of the present invention, the cleaning member includes a rotating rod, and the outer wall of the rotating rod is provided with a cleaning cover that is in close contact with the inspection camera lens.

[0015] As a further solution of the present invention, the transmission mechanism includes a first synchronous wheel, a synchronous belt and a second synchronous wheel. The first synchronous wheel is fixed coaxially with the gear, and the second synchronous wheel is fixed to the end face of the rotating rod. The first synchronous wheel and the second synchronous wheel are connected by a synchronous belt. The second synchronous wheel is set on the inner wall of the cabinet through shaft rotation. When the first synchronous wheel rotates, the synchronous belt can drive the second synchronous wheel to rotate, and then realize the rotation of the rotating rod, so that the cleaning sleeve rotates to clean the lens of the moving inspection camera, and the cleaning effect is better.

[0016] As a further solution of the present invention, a support rod is fixed to the bottom of the inspection camera, a connecting seat is fixed to the bottom of the support rod, and a chassis is fixed to the bottom of the connecting seat by bolts. The chassis is adapted to the bottom of the cabinet, and is provided with a support rod, a connecting seat and a chassis. When the inspection camera moves, the chassis is driven to move synchronously to ensure that the partition and the chassis are close to or away from each other. When they are close to each other, the cabinet, partition and chassis are ensured to completely protect the inspection camera, so that the inspection camera is effectively stored. When the inspection camera moves down and needs to work, the partition and the chassis are away from each other to achieve rapid work.

[0017] As a further solution of the present invention, a mounting box is fixed to the top of the inner wall of the cabinet, and a circuit board, a controller and a wireless connection module are installed in the mounting box. A through hole is opened on the mounting box, and the electric push rod is arranged through the hole.

When moving downward, the second rack connected to the connecting rod moves downward, and due to the downward movement of the second rack, the gear meshing with it rotates clockwise, thereby realizing the upward movement of the first rack meshing with the gear, so that the partition moves up, and the partitions located at both ends of the cabinet move up, so that the two ends of the cabinet are opened, so that the inspection camera that moves downward is exposed and works. In the process of moving downward, due to the rotation of the gear, the first synchronous wheel rotates, and the second synchronous wheel is realized by the synchronous belt to rotate, thereby realizing the rotation of the rotating rod, so that the cleaning sleeve on the rotating rod cleans the lens of the inspection camera, and then the inspection can be carried out freely. Similarly, when the inspection camera is not used for inspection, the inspection camera can be driven to move upward by the electric push rod, and the gear rotates counterclockwise. Similarly, the partition moves down, and the rotating rod rotates synchronously, and the lens of the inspection camera that needs to be stored is cleaned again, thereby strengthening the protection of the inspection camera.

When moving downward, the second rack 8 connected to the connecting rod 6 moves downward. Due to the downward movement of the second rack 8, the gear 12 meshing with it rotates clockwise, thereby realizing the upward movement of the first rack 201 meshing with the gear 12, so that the partition 2 moves upward. The partitions 2 located at both ends of the cabinet 1 move upward, so that the two ends of the cabinet 1 are opened, so that the inspection camera 3 that moves downward is exposed and works.

[0040] Cleaning parts 13 are installed at the positions near the partition 2 at both ends of the inner wall of the cabinet 1.

The electric push rod 4 drives the mounting plate 5 to move downward, and the inspection camera 3 is synchronously moved downward. When moving downward, the second rack 8 connected to the connecting rod 6 moves downward. As the second rack 8 moves downward, the gear 12 meshing with it rotates clockwise, thereby realizing the upward movement of the first rack 201 meshing with the gear 12, so that the partition 2 moves upward. The partitions 2 at both ends of the cabinet 1 move upward, so that both ends of the cabinet 1 are open, which is convenient for the inspection camera to move downward. The inspection camera 3 is exposed and starts working, and in the process of moving downward, due to the rotation of the gear 12, the first synchronous wheel 141 rotates, and the second synchronous wheel 143 rotates through the synchronous belt 142, and then the rotating rod 131 rotates, so that the cleaning sleeve 132 on the rotating rod 131 cleans the lens of the inspection camera 3, and then the inspection can be carried out freely. Similarly, when the inspection camera 3 is not used for inspection, the inspection camera 3 can be driven to move up by the electric push rod 4, and the gear 12 rotates counterclockwise. Similarly, the partition 2 moves downward, and the rotating rod 131 rotates synchronously, and the lens of the inspection camera 3 that needs to be stored is cleaned again.

[0043] In this embodiment, a first limiting groove 202 is provided on the outer wall of the first rack 201, and a second limiting strip 11 corresponding to the first limiting groove 202 is fixed on the inner wall of the cabinet 1. The first limiting groove 202 is slidably arranged in the second limiting strip 11 to ensure that when the electric push rod 3 moves the mounting plate 5, the moving first rack 201 can move more stably under the action of the second limiting strip 11.

[0044] In this embodiment, a second limiting groove 9 is provided on the outer wall of the second rack 8, and a first limiting strip 10 corresponding to the second limiting groove 9 is fixed on the inner wall of the cabinet 1. The second limiting groove 9 is slidably arranged in the first limiting strip 10 to ensure that when the electric push rod 3 moves the mounting plate 5, the moving second rack 8 can move more stably under the action of the first limiting strip 10.

[0045] In this embodiment, the cleaning member 13 includes a rotating rod 131, and the outer wall of the rotating rod 131 is provided with a cleaning sleeve 132 that is close to the lens of the inspection camera 3.
