[0002] High-voltage cabinets refer to electrical products with voltage levels of 3.6kV to 550kV, which are used for switching, control or protection in power generation, transmission, distribution, power conversion and consumption in power systems. They are important equipment in power systems.

[0003] In order to ensure the normal operation and safety of the high-voltage cabinet, it is generally necessary for staff to conduct regular inspections of the high-voltage cabinet.

[0004] The inspection staff mainly inspects the appearance, interior and operating status of the high-voltage cabinet. When the inspection staff inspects the operating status of the high-voltage cabinet, they mainly observe whether the high-voltage cabinet is running smoothly, whether the temperature and humidity inside the high-voltage cabinet are normal, whether there is abnormal overheating, and whether there is any abnormal sound or odor.

[0005] At present, in order to reduce the workload of inspection personnel, a monitoring component for humidity monitoring and smoke monitoring inside the high-voltage cabinet is generally installed inside the high-voltage cabinet, and the operation inside the high-voltage cabinet is monitored in real time through the monitoring component. At present, when installing the monitoring component, the monitoring component is generally directly fixed on the inner wall of the high-voltage cabinet. When the internal situation of the high-voltage cabinet is monitored by the monitoring component, there is a defect of a small monitoring range. Utility Model Content

[0006] In order to improve the monitoring range of the monitoring component, the present application provides a high-voltage cabinet monitoring device.

[0007] The present application provides a high-voltage cabinet monitoring device that adopts the following technical solution:

[0008] A high-voltage cabinet monitoring device comprises a rotary drive assembly arranged on the inner side wall of the high-voltage cabinet, a telescopic drive assembly arranged on the rotary drive assembly and a processor arranged on the outer side wall of the high-voltage cabinet, wherein the monitoring assembly is installed on the telescopic drive assembly, the rotary drive assembly is used to drive the telescopic drive assembly and the monitoring assembly to perform rotary reciprocating motion, the telescopic drive assembly is used to make the monitoring assembly move radially along the rotary reciprocating direction, and the rotary drive assembly, the telescopic drive assembly and the monitoring assembly are all electrically connected to the processor.

[0009] By adopting the above technical solution, when the operating environment inside the high-voltage cabinet is monitored by the monitoring component, the processor controls the operation of the rotary drive component and the telescopic drive component, and the rotary drive component causes the monitoring component to perform a rotary reciprocating motion along the rotation center, thereby increasing the monitoring range of the monitoring component. The telescopic drive component is installed on the rotary drive component, and when the monitoring component performs a rotary reciprocating motion, the rotary reciprocating radius of the monitoring component is adjusted by the telescopic drive component, thereby further increasing the monitoring range of the monitoring component. At the same time, it is convenient for the monitoring component to adapt to high-voltage cabinet spaces of different sizes.

[0010] Optionally, the rotary drive assembly includes a turntable arranged on the inner side wall of the high-voltage cabinet, a driving wheel arranged on the inner side wall of the high-voltage cabinet near the turntable, and a driving motor arranged on the inner side wall of the high-voltage cabinet for driving the driving wheel to rotate. The turntable and the driving wheel are both rotatably matched with the inner side wall of the high-voltage cabinet through a mounting seat, the turntable and the driving wheel are connected by a drive belt, the drive motor and the processor are electrically connected, and the telescopic drive assembly is installed on the turntable.

[0011] By adopting the above technical solution, when the rotary drive assembly is working, the driving motor drives the driving wheel to rotate, and the driving wheel drives the turntable to rotate synchronously through the driving belt. Since the monitoring assembly rotates with the turntable, the convenience of the monitoring assembly to perform rotary reciprocating motion is improved. At the same time, the driving wheel drives the turntable to rotate through the driving belt, which improves the rotation stability of the turntable and reduces the working noise when the turntable is driven to rotate.

[0012] Optionally, the mounting seat includes a mounting plate arranged on the inner side wall of the high-voltage cabinet, a mounting rod arranged on the side of the mounting plate close to the turntable, and a positioning portion arranged on the mounting plate close to the mounting rod, the mounting rod rotates through the turntable, and the positioning portion is used to position the turntable.

[0013] By adopting the above technical solution, when installing the rotary disk, the installation disk is pre-installed on the inner wall of the high-voltage cabinet, the installation rod is rotated to pass through the rotary disk, and the rotary disk is positioned by the positioning part, thereby improving the working stability and installation convenience of the rotary disk. When the rotary disk is working, the larger contact area between the installation disk and the inner wall of the high-voltage cabinet reduces the possibility of the installation disk turning over, thereby improving the working stability of the rotary disk.

[0014] Optionally, the positioning portion includes a positioning block disposed on the mounting plate, a positioning groove is formed on a side of the positioning block close to the rotating plate, and the rotating plate is partially located inside the positioning groove.

[0015] By adopting the above technical solution, when the turntable is working, since the turntable is partially located inside the positioning groove, the inner wall of the positioning groove limits the turntable, thereby reducing the possibility of the turntable detaching from the mounting rod and improving the working stability of the turntable.

[0016] Optionally, the positioning portion further includes a plurality of balls arranged on one side of the inner wall of the positioning groove close to each other, and the plurality of balls are all in rolling cooperation with the turntable.

[0017] By adopting the above technical solution, when the turntable is working, due to the rolling cooperation between the ball bearings and the turntable, the turntable is positioned by the ball bearings, thereby reducing the rotational resistance of the turntable, improving the convenience of the turntable, and reducing the energy loss of driving the turntable to rotate.

[0018] Optionally, the telescopic drive assembly includes an active telescopic rod with one end arranged on the rotary drive assembly and a driven telescopic group with one end arranged on the rotary drive assembly, the driven telescopic group includes a plurality of coaxially nested telescopic sleeves, two adjacent telescopic sleeves are slidably matched, one end of the active telescopic rod away from the rotary drive assembly is connected to the telescopic sleeve away from the rotary drive assembly, the active telescopic rod is electrically connected to the processor, and the monitoring assembly is arranged on the telescopic sleeve away from the rotary drive assembly.

[0019] By adopting the above technical solution, the driven telescopic group is composed of a plurality of coaxially nested telescopic sleeves, and two adjacent telescopic sleeves are slidably matched, and the overall length of the driven telescopic group is changed by making the two adjacent telescopic sleeves slide relative to each other. When the overall length of the driven telescopic group needs to be changed, the overall length of the active telescopic rod is changed, and the end of the active telescopic rod drives the telescopic sleeve away from the rotary drive component to move, thereby improving the convenience of changing the overall length of the driven telescopic group and the convenience of changing the size of the rotary reciprocating radius of the monitoring component. At the same time, the driven telescopic group is composed of a plurality of telescopic sleeves, which reduces the overall weight of the driven telescopic group, thereby reducing the energy loss of the rotary drive component driving the telescopic drive component to operate.

[0020] Optionally, a guide rod is threadedly connected to the wall of the telescopic sleeve, and a guide groove is opened on the outer wall of the telescopic sleeve along the axial direction of the telescopic sleeve, and the end of the guide rod on the larger diameter of the two adjacent telescopic sleeves slides with the guide groove of the smaller diameter telescopic sleeve.

[0021] By adopting the above technical solution, the guide rod is threadedly connected to the tube wall of the telescopic sleeve, and the end of the guide rod is located inside the guide groove of the adjacent telescopic sleeve. The guide rod limits the telescopic sleeve through the inner wall of the guide groove, thereby reducing the possibility of relative rotation between the two adjacent telescopic sleeves, thereby improving the working stability of the monitoring component. At the same time, since the guide rod is threadedly connected to the tube wall of the telescopic sleeve, it is convenient to move the guide rod on the tube wall of the telescopic sleeve by rotating the guide rod, thereby improving the convenience of installing and removing the two adjacent telescopic sleeves.

[0022] Optionally, a rotation hole is formed on one end of the guide rod away from the guide groove, and a rotation pin is inserted into and fitted in the rotation hole.

[0023] By adopting the above technical solution, when the guide rod needs to be rotated, the staff inserts the rotating pin into the rotating hole and rotates the guide rod by twisting the rotating pin, thereby improving the convenience of rotating the guide rod and further reducing the overall weight of the guide rod.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the operating environment inside the high-voltage cabinet is monitored by the monitoring component, the processor controls the operation of the rotary drive component and the telescopic drive component. The rotary drive component causes the monitoring component to perform a rotary reciprocating motion along the rotary center, thereby increasing the monitoring range of the monitoring component. The telescopic drive component is installed on the rotary drive component. When the monitoring component performs a rotary reciprocating motion, the rotary reciprocating radius of the monitoring component is adjusted by the telescopic drive component, thereby further increasing the monitoring range of the monitoring component. At the same time, it is convenient for the monitoring component to adapt to high-voltage cabinet spaces of different sizes.

[0026] 2. When the rotary drive assembly is working, the driving motor drives the driving wheel to rotate, and the driving wheel drives the turntable to rotate synchronously through the driving belt. Since the monitoring assembly rotates with the turntable, the convenience of the monitoring assembly to perform reciprocating motion is improved. At the same time, the driving wheel drives the turntable to rotate through the driving belt, which improves the rotation stability of the turntable and reduces the working noise when the turntable is driven to rotate.
