Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cable grounding boxes, in particular to a high-voltage cable grounding box. Background Art

[0002] The high-voltage cable grounding box is used to place the grounding wire and protect the grounding wire. The grounding box and the grounding busbar share the same function, which is to collect the connection equipment of the grounding wire. It is specifically divided into direct grounding box, protective grounding box, three-phase cross-interconnected grounding box, and three-phase six-wire grounding box. The existing high-voltage cable grounding box can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] For the sake of safety, the high-voltage cable grounding boxes widely used in the market usually have an observation port installed on the cabinet door, so that inspectors can directly inspect the inside of the equipment from the outside. However, since the observation port is exposed to the outside, it is easy for a lot of dust to adhere to its surface, causing line of sight obstruction and inconvenience for observers to inspect. For this reason, we propose a high-voltage cable grounding box to solve the above problem. Utility Model Content

[0006] As a further preferred embodiment of the present technical solution, the locking assembly includes a threaded groove formed in the mounting seat, a screw threadedly connected in the threaded groove, and a threaded hole formed in the mounting block, and the end of the screw is also threadedly connected to the threaded hole on the mounting block.

[0007] As a further preferred embodiment of the present technical solution, a sleeve is fixed on the right side of the observation window, and the rear end of the brush plate can be inserted into the sleeve.

[0008] As a further preferred embodiment of the present technical solution, the inner wall of the sliding sleeve is fully fitted with the outer wall of the sliding rod, and the sliding sleeve is slidably connected to the sliding rod.

[0009] As a further preferred embodiment of the present technical solution, two ends of the return spring are respectively connected to the outer wall of the sliding sleeve and the outer wall of the top plate, and the sliding sleeve is elastically connected to the top plate through the return spring.

[0010] As a further preferred embodiment of the present technical solution, a turning handle is provided at the front end of the screw rod, and an anti-slip groove is provided on the turning handle.

[0011] The utility model provides a high-voltage cable grounding box, which has the following beneficial effects:

[0012] 1. The utility model installs a brush plate which can move laterally on the outside of the observation window on the opening and closing cabinet door. When it is necessary to clean the dust on the surface of the observation window, the top plate can be pushed to allow the guide slider to drive the brush plate to move laterally along the guide rail to the front end of the observation window, and the two groups of reset springs release the elastic force to push the two groups of sliding sleeves to move backward, so that the brush plate is tightly attached to the surface of the observation window under the drive of the two groups of sliding sleeves, and then the top plate is pushed back and forth laterally to allow the brush plate to move back and forth laterally along the surface of the observation window, so that the brush plate can quickly clean the dust on the surface of the observation window during the movement, thereby facilitating the user to observe the inside of the high-voltage cable grounding box shell through the observation window, thereby improving the convenience of using the device.

[0013] 2. The utility model has a rotatable screw installed in the mounting seat. When the brush plate is used for a long time, the screw can be rotated to allow the screw to leave the threaded hole on the mounting block under the action of the thread, so that the screw can quickly release the fixation of the mounting block, making it easy for the brush plate to pull the mounting block out of the mounting groove on the mounting seat, thereby facilitating the cleaning and replacement of the brush plate.
