Description

Technical Field

[0001] The utility model relates to the field of ground wire management, in particular to a ground wire management device for a high-voltage power transmission line. Background Art

[0002] The ground wire of the high-voltage transmission line is the lifeline to ensure the personal safety of the workers. The operation of installing and removing the ground wire is the most dangerous operation in electrical operations. Once an accident occurs, it will have a great impact.

[0003] In the prior art, in order to facilitate the management of the ground wires of the high-voltage transmission lines, it is necessary to use a management cabinet to classify and store the ground wires of the high-voltage transmission lines. However, there are many types of ground wires for high-voltage transmission lines, including insulating rods, testers, grounding wires, insulating gloves, insulating clothing, safety helmets, etc. When the insulating rods need to be managed and stored, the grounding wires are wrapped around the surface of the insulating rods, and then the insulating rods are separated and fixed inside the management box with clamps. However, when taking the insulating rods, the clamps on the outside of the insulating rods need to be removed one by one. When they are not needed, the insulating rods can be put back in a fixed position and then the clamps can be installed to fix them. The operation is inconvenient and it is not convenient for personnel to manage and record.

[0004] Therefore, it is necessary to invent a ground wire management device for high-voltage transmission lines. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ground wire management device for a high-voltage transmission line, comprising a box body and a management frame, the management frame is installed inside the box body, a top plate is installed on the upper end of the management frame, a bottom plate is installed on the bottom of the management frame, a placement plate is installed in the middle of the management frame, positioning components are symmetrically installed on both sides of the management frame, and a limiting component is installed on the side of the positioning component away from the management frame.

[0007] Based on the above features: the placement plate is installed in the inner cavity of the box, so that the top plate on the upper end of the placement plate is in close contact with the upper end of the inner cavity of the box, and the bottom plate on the lower end of the placement plate is in close contact with the lower end of the inner cavity of the box. The placement plate can distribute multiple spaces in the middle of the management rack, which is convenient for classifying and placing tools such as testers, insulating gloves, insulating clothing, and safety helmets. The grounding wire can be wrapped around the surface of the insulating rod. When the insulating rod needs to be stored, the management rack can be pulled out, and then the limit assembly is pulled open so that the insulating rod can be fixed at intervals on the inside of the positioning assembly. When the insulating rod is fixed, the limit assembly can be reinserted on one side of the positioning assembly to facilitate limiting the insulating rod, and finally the management rack can be pushed back into the box.

[0008] Preferably, T-shaped sliding blocks are symmetrically installed on the inner walls at both ends of the box body, and observation windows are symmetrically opened at the lower ends of both sides of the box body.

[0009] Based on the above features: T-shaped slide grooves are symmetrically provided at both ends of the top plate and the bottom plate, and the top plate and the bottom plate are slidably connected by the T-shaped slide grooves and the T-shaped sliders, so that the management rack can be pulled and pushed easily.

[0010] Preferably, grooves are spaced apart on the upper end of the bottom plate, a movable plug is installed on the upper end of the inner cavity of the groove, a through hole is opened at the lower end of the groove away from the management frame, and a lamp bead is installed inside the through hole.

[0011] Based on the above features: it is convenient for personnel to check whether there is still space to fix the insulating rod at the outer end of the box without pulling out the management frame for confirmation.

[0012] Preferably, a controller is installed at the lower end of the inner cavity of the groove, and a contact switch is installed at the upper end of the controller.

[0013] Based on the above features: when the movable plug descends and contacts the contact switch, the contact switch is electrically connected to the controller, so that the contact switch turns on the controller, and the controller is electrically connected to the lamp bead, and the lamp bead can emit light.

[0014] Preferably, a convex rod and a buffer spring are installed at the bottom of the movable plug block, and the convex rod is located in the middle of the buffer spring.

[0015] Based on the above characteristics: when the movable plug-in block descends, the convex rod will contact the contact switch, at which time the buffer spring will be squeezed and deformed, and when the buffer spring rebounds the movable plug-in block, the convex rod will separate from the contact switch, and the lamp bead will go out and will not emit light.

[0016] Preferably, the positioning assembly comprises a positioning plate and slots spaced apart on the surface of the positioning plate, and positioning slots are provided between adjacent slots.

[0017] Based on the above features: the positioning plates are fixed on both sides of the management frame, and the insulating rods can be limited inside the card slots.

[0019] Based on the above features: after the insulating rod is installed, the limit baffle can be inserted into the positioning slot using the guide rod. At this time, the limit baffle will fit onto one side surface of the positioning plate to prevent the insulating rod from detaching from the slot. When the management frame is pushed into the box, the side of the limit baffle away from the positioning plate will use rollers to roll in contact with the inner wall of the box, which can not only enhance the movement effect of the management frame, but also tighten the limit baffle to prevent the limit baffle from falling off by itself.

[0020] The beneficial effects of the utility model are:

[0021] 1. It is convenient to manage and store the grounding tools of high-voltage transmission lines. The placement plate can distribute multiple spaces in the middle of the management frame, which is convenient for the classification and placement of tools such as testers, insulating gloves, insulating clothes, and safety helmets. The grounding wire can be wrapped around the surface of the insulating rod. When the insulating rod needs to be stored, the management frame can be pulled outward, and then the limit baffle is pulled outward to clamp the insulating rods one by one in the inner side of the slot on one side of the positioning plate. When the insulating rod is inserted, the limit baffle can be inserted into the positioning slot using the guide rod. At this time, the limit baffle will fit on one side of the positioning plate. Finally, the management frame can be pushed into the box.

[0022] 2. When the management rack is pushed into the box, the top plate and the bottom plate are connected by T-shaped grooves and T-shaped sliders, which makes it easy for the management rack to be pulled and pushed. The side of the limit baffle away from the positioning plate will use rollers to roll with the inner wall of the box, which can not only enhance the movement effect of the management rack, but also tighten the limit baffle to prevent it from falling off by itself.

[0023] 3. When the insulating rod is installed, the lower end of the insulating rod will press the movable plug-in. At this time, the movable plug-in will squeeze the buffer spring back to the inner cavity of the groove, and when the movable plug-in descends, it will use the convex rod to contact the contact switch, and then the contact switch will use the controller to turn on the lamp bead to emit light. When the insulating rod is taken out, the buffer spring can rebound the movable plug-in, and the convex rod will also be separated from the contact switch, so that the lamp bead will not emit light when it is turned off, which is convenient for personnel to check whether there is still a position to fix the insulating rod at the outer end of the box without pulling out the management frame for confirmation.
