[0002] In power grid projects, power outages and maintenance work are frequently involved. When workers are doing power outages for maintenance, they need grounding wires. Grounding wires are an important tool for workers to ensure that voltage is not generated when power is turned off. Grounding wires need to be connected to lines, equipment, etc. through grounding rods and form a safety loop with the earth. In order to make it easy for grounding rods to be hung on cables at high altitudes, existing grounding rods mostly use hook-type clamping devices.

[0003] The prior art discloses a utility model patent document entitled "An improved single-tongue grounding rod that is easy to disassemble and easy to retract", with an authorization announcement number of CN206282990U and an authorization announcement date of 20170627. The utility model patent document comprises a grounding wire clamp and an insulating rod. The grounding wire clamp is provided with a threaded fixing cover, a tongue piece, a convex head, an n-shaped hook, a steel wire, a return spring and a pressure-type joint. The n-shaped hook is provided with a hole I, a concave groove and a hole II; the insulating rod is provided with a π-shaped handle, the π-shaped handle is provided with a groove ring, and the groove ring is provided with a groove. The tail end of the tongue piece is fixed at the connection between the n-shaped hook and the threaded fixing cover by a return spring. The utility model is easy to disassemble and prevent from falling off, easy to retract, and avoid electric shock to the staff; protect the grounding rod and the wire: since the tongue piece and the wire are separated, when the grounding rod is removed, the staff can avoid rough behaviors such as forcible pulling and dragging, thereby protecting both the grounding rod and the wire and the adjacent equipment.

[0004] However, the grounding rod of the above patent document has the following problems when in use: when the grounding rod needs to be removed, one needs to hold the insulating rod with one hand and manually operate the π-shaped handle with the other hand, which requires two-handed operation and is quite troublesome. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a grounding rod that is easy to operate with one hand, so as to solve the technical problem that the current grounding rod needs to be removed with both hands, which is troublesome.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The specific implementation is as follows:

[0025] Embodiment 1, as Figure 1-4As shown, a grounding rod that is convenient for one-hand operation, the grounding rod comprises a wire clamping device and an insulating rod 7, a handle 71 for holding by hand is arranged at the lower end of the insulating rod 7, the wire clamping device comprises a wire hanging hook 1 with an opening downward and a locking structure 2, the locking structure 2 is a U-shaped structure, the opening direction of the locking structure 2 is toward the hook tongue direction of the wire hanging hook 1, the wire hanging hook 1 is provided with a slide groove 11 on the side close to the insulating rod 7, the locking structure 2 is stuck in the slide groove 11 and can slide along the extension direction of the slide groove 11, and the opening of the locking structure 2 is closed or opened by the hook tongue of the wire hanging hook 1 when sliding in the slide groove 11; when in use, the locking structure 2 is locked. The opening of the structure 2 is placed in an open state, the handle 71 of the insulating rod 7 is held and the cable is inserted into the U-shaped opening of the locking structure 2. At this time, the insulating rod 7 is pulled or under the action of the gravity of the grounding rod as a whole, the locking structure 2 is driven by the cable to slide upward, so that the hook tongue of the hanging hook 1 closes the opening of the locking structure 2, and the cable is stably hooked. When it is necessary to remove the wire clamping device, only one hand needs to hold the handle 71 and push it upward, and the cable drives the locking structure 2 to slide downward along the slide groove 11. At this time, the opening of the locking structure 2 is opened, and the wire clamping device can be removed from the cable, so that one-handed operation is realized, and the operation is easier.

[0026] Furthermore, a spring 8 is connected between the top of the locking structure 2 and the top of the slide slot 11. When the spring 8 is in the initial state, the opening of the locking structure 2 is in an open state. When hooking the cable, the opening of the locking structure 2 is in an open state under the action of the spring 8. At this time, the insulating rod 7 can be directly held to hook the cable, eliminating the trouble of manually moving the locking structure 2 to a suitable state in advance.

[0027] Furthermore, the locking structure 2 includes a pulling rod 21, a linkage rod 23 and a hard connecting rod 22. The pulling rod 21 and the linkage rod 23 are parallel to each other. The right ends of the pulling rod 21 and the linkage rod 23 pass through the slide groove 11. At the same time, the right ends of the pulling rod 21 and the linkage rod 23 are connected by the hard connecting rod 22. When in use, the pulling rod 21 contacts the cable and is moved by the cable. The pulling rod 21 drives the linkage rod 23 to move, thereby realizing the opening and closing of the opening of the locking structure 2.

[0028] Furthermore, a sliding joint A212 is provided between the upper end of the hard connecting rod 22 and the pulling rod 21, and the sliding joint A212 and the hard connecting rod 22 and the pulling rod 21 are connected by plugging, and the thickness of the sliding joint A212 is less than the thickness of the hard connecting rod 22 and the pulling rod 21 on both sides thereof; a sliding joint B232 is provided between the lower end of the hard connecting rod 22 and the linkage rod 23, and the sliding joint B232 and the hard connecting rod 22 and the linkage rod 23 are connected by plugging, and the thickness of the sliding joint A212 is less than the thickness of the hard connecting rod 22 and the pulling rod 21 on both sides thereof; the thickness of the sliding joint B232 is less than the thickness of the hard connecting rod 22 and the linkage rod 23 on both sides thereof; when the locking structure 2 slides, since the sliding joint is thinner than the pulling rod 21 and the linkage rod 23, the locking structure 2 is prevented from tilting during sliding.

[0029] Furthermore, the upper side of the linkage rod 23 is connected to the clamp rod 3 through the compression spring 5, and a tension rope 6 is fixed to the lower side of the clamp rod 3. The tension rope 6 can be made of steel wire rope, and a fixed pulley B42 is arranged below the connection between the tension rope 6 and the clamp rod 3, and the fixed pulley B42 is fixed on the linkage rod 23. A fixed pulley A41 is fixed to the upper side of the linkage rod 23 on the right side of the slide groove 11, and a support rod 12 protruding to the right is arranged on the upper side of the slide groove 11. The tension rope 6 passes around the fixed pulley B42 and the fixed pulley A41 in turn and passes through the through hole on the pull rod 21 and is finally connected to the support rod 12; under the support of the spring 8, the tension rope 6 is tightened, and the tension rope 6 pulls the clamp rod 3 to compress the compression spring 5, so that the clamp rod 3 is close to the linkage rod 23, and when the locking structure 2 slides upward, the tension rope 6 is loosened to reduce the pressure on the compression spring 5, and the compression spring 5 pushes the clamp rod 3 upward and close to the linkage rod 23, which tightens the cable and better fixes the position of the cable.

[0030] Furthermore, a slide bar 32 is fixed to the lower side of the clamp rod 3, and an opening 231 is processed on the linkage rod 23 for the slide bar 32 to pass downward; during the sliding process of the clamp rod 3, the movement direction of the clamp rod 3 is stable due to the limiting effect of the slide bar 32 and the opening 231.

[0031] Furthermore, a downwardly concave lower groove 31 is processed in the upper middle part of the clamp rod 3, and an upper groove 211 matching with the lower groove 31 is processed on the lower side of the pull rod 21, so as to facilitate the accurate fixation of the cable position.

[0032] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
