Description

Portable Grounding Device

technical field

The utility model relates to an electric appliance, in particular to a portable grounding device.

Background technique

In the power system, it is often necessary to overhaul the transmission line. During the maintenance, a grounding device is attached to the line to ensure the safety of the line maintenance personnel; the existing grounding device usually includes a hook, a handle is provided at the bottom of the hook, and a grounding wire is provided on the hook. ; Because the length of the existing grounding wires is relatively short, when the height of the transmission line for maintenance is high, the staff will climb from the pole or the transmission tower to a position equal to the height of the transmission line, and then hang the grounding wire. Then go to the working face to work, the process is laborious and dangerous.

Therefore, there is a need for a portable grounding device, which can meet the needs of hanging ground wires for high-altitude operations, shorten the working hours of maintenance operations, improve the work efficiency of staff, and reduce the risk of operation.

Utility model content

In view of this, the purpose of this utility model is to provide a portable grounding device, which can meet the needs of hanging ground wires for high-altitude operations, shorten the working time of maintenance operations, improve the working efficiency of staff, and reduce the risk of operation.

The portable grounding device of the present utility model includes a hook, a handle and a grounding wire. The handle is made of plastic and includes a first rod body, a second rod body and a joint I; the first rod body is provided with an axial channel, and the second rod body The two rods coaxially extend into the axial channel and can move along the axial channel. The joint I is sleeved on the first rod body and the second rod body and is threadedly connected with the second rod body; the hook is connected to the second rod body through the joint II. connected; the joint II includes a connected lower screw rod and a "concave" upper mounting seat, the lower screw rod coaxially extends into the second rod body and is threaded, and the hook is connected to the upper mounting seat.

Further, the first rod body and the joint I are integrally formed.

Further, the lower end of the hook extends into the empty slot of the upper mount and is hinged to the upper mount by bolts.

Further, the hook is in the shape of a "J" and is provided with a double-tongued spring clip for clamping the wire.

Further, the ground wire is connected to the ground pole of the hook through the wiring board.

Further, the length of the first rod body is 1/2-2/3 of the length of the second rod body.

Beneficial effects of the utility model: In the portable grounding device of the utility model, the spiral movement between the second rod body and the joint I makes the second rod body move along the axial channel, thereby making the handle stretchable as a whole, and the handle has a longer length when working at heights. The length of the handle is relatively short when it is idle, which is not only convenient for storage, but also meets the needs of hanging ground wires for high-altitude operations, shortens the working time of maintenance operations, improves the work efficiency of the staff, and reduces the risk of operation; Moreover, through the joint II, the handle and hook are detachable structures, which can be stored independently, and then assembled when in use, further improving its portability.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model.

detailed description

Fig. 1 is a schematic structural view of the present utility model, as shown in the figure: the portable grounding device of this embodiment includes a hook 1, a handle and a grounding wire 3, the handle is made of plastic and includes a first rod body 21, a second rod body 22 and joint I23; the first rod body 21 is provided with an axial passage 21a, the second rod body 22 coaxially extends into the axial passage 21a and can move along the axial passage 21a, and the joint I23 is sleeved on the first The rod body 21 is threadedly connected with the second rod body 22 and the second rod body 22; the hook 1 is connected with the second rod body 22 through the joint II; The mounting seat 42, the lower screw rod 41 coaxially extends into the second rod body 22 and is threaded, and the hook 1 is connected to the upper mounting seat 42; the handle is made of hard plastic to ensure its strength; meanwhile, the first rod body 21 and the second rod body 22 are both hollow structures, so that the handle has a lighter quality; the length of the first rod body 21 is 1/2-2/3 of the length of the second rod body 22, and the second rod body 22 has greater freedom of movement The first rod body 21 can be integrally formed with the joint I23 to improve the structural strength of the handle and prolong the service life; the ground wire 3 is connected to the ground electrode of the hook 1 through the terminal board 6, which is convenient for connection; the hook 1 is in the shape of "J" There is also a double-tongue spring clip 11 for clamping the wire; the spiral movement between the second rod body 22 and the joint I23 makes the second rod body 22 move along the axial channel 21a, so that the handle is stretched as a whole. The handle has a longer length, and the handle has a shorter length when it is idle, which is convenient for storage and also meets the needs of hanging the ground wire 3 for high-altitude operations, shortens the working time of maintenance operations, improves the work efficiency of the staff, and reduces Moreover, through the joint II, the handle and the hook 1 are detachable structures, which can be stored independently, and then assembled when in use, further improving its portability.

In this embodiment, the lower end of the hook 1 extends into the empty slot of the upper mounting seat 42 and is hinged to the upper mounting seat 42 through the bolt 5; the hook 1 is hinged to the joint II, and the hook 1 can move left and right from the axis of the handle. In the case that the hook 1 is vertically connected to the inclined wire, the handle can be rotated and adjusted relative to the horizontal plane to ensure that the hook 1 has a sufficient contact area with the connected wire to better guide the current leakage and meet the grounding requirements. Thermal calibration and electrical calibration of line 3.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
