Description

Technical Field

[0001] This utility model relates to the field of conductor winding technology, and more specifically, to a grounding resistance meter measuring wire winding device. Background Technology

[0002] According to the "Operating Regulations for 500kV Overhead Transmission Lines," a full-line grounding resistance measurement is required every 5 years, and a 2km protection section of the substation incoming line is measured annually. During the annual spring inspection and electrical preventative testing, grounding resistance meters are frequently used. However, during use, the measuring wire often becomes tangled, knotted, or broken. Untangling these issues is time-consuming and tedious, thus affecting the lifespan of the measuring wire. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a grounding resistance meter measuring wire reel, which aims to improve the problem that the measuring wire often gets tangled, knotted, twisted, or broken.

[0004] This utility model is implemented as follows: This utility model provides a grounding resistance meter measuring wire reel, including a shaft, a drive wheel, and two wire holders.

[0005] The grip shaft has a hollow structure and an opening that can form a grip.

[0006] The drive wheel is rotatably connected to the grip shaft, and the drive wheel has a first winding position and a second winding position.

[0007] Both lead frames are connected to the grip shaft, and their ports extend to the first take-up position and the second take-up position, respectively.

[0008] In one embodiment of this utility model, a rotating rod is installed on the side of the drive wheel away from the guide frame.

[0009] In one embodiment of this utility model, the drive wheel has two wire end holes.

[0010] In one embodiment of this utility model, the rotating rod is connected to the driving wheel via a fixed seat, and the fixed seat is fitted with an elastic element that abuts against the rotating rod.

[0011] In one embodiment of the present invention, the conductor frame has a conductor hole through which the measuring wire passes.

[0012] The beneficial effects of this utility model are as follows: The grounding resistance meter measuring wire reel obtained through the above design allows for the following operation: Since the measuring wire length is fixed, the driving wheel rotates under external power according to the coaxial transmission principle. Because the driving wheel is connected to the shaft, the rotation of the driving wheel will inevitably drive the rotation of the shaft. Therefore, by manufacturing a coaxial circular reel proportionally based on the measuring wire length ratio, two measuring wires can be simultaneously and synchronously wound and unwound.

[0013] Improve the efficiency of winding and unwinding the measuring wire, prevent the measuring wire from bending into dead angles and causing strand breakage and damage, and improve the efficiency of grounding resistance measurement;

[0014] The use of a 500kV transmission line grounding resistance meter reel eliminates the need for personnel to manually wind and unwind the wire during grounding resistance measurement, reducing the likelihood of the measuring wire breaking or becoming unusable due to twisting. This improves the service life of the grounding resistance measuring wire and shortens the time required to measure the grounding resistance of each tower. Attached Figure Description

[0027] Example

[0028] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a ground resistance meter measuring wire reel, including a grip shaft 100, a drive wheel 200 and two conductor frames 300.

[0029] Please refer to Figure 1 and Figure 2 The drive wheel 200 rotates on the grip shaft 100. When the drive wheel 200 rotates, the two measuring wires are guided by the guide frame 300 and wound around the drive wheel 200 at the corresponding positions in sequence.

[0030] Please see Figure 1 and Figure 2 The grip shaft 100 is a hollow structure and has two openings that can form a grip 110. The fingers can be inserted into the corresponding openings so that the grip shaft 100 can be gripped tightly in the hand.

[0031] Please see Figure 1 , Figure 2 and Figure 3The drive wheel 200 is rotatably connected to the grip shaft 100. The drive wheel 200 has a first winding position 210 and a second winding position 220. The drive wheel 200 also has two end holes 240. One end of each of the two measuring wires is passed through the corresponding end hole 240, causing the measuring wires to be wound up at one end. When the drive wheel 200 rotates, the two measuring wires can be directly wound onto the first winding position 210 and the second winding position 220. Two lead frames 300 are both connected to the grip shaft 100, and their ends extend to the first winding position 210 and the second winding position 220, respectively. Specifically, the lead frame 300 has a lead hole 310 for the measuring wires to pass through, which guides the measuring wires, ensuring that the two measuring wires are accurately wound onto the corresponding first winding position 210 and second winding position 220.

[0032] Please see Figure 1 and Figure 2 A rotating rod 230 is installed on the side of the drive wheel 200 away from the guide frame 300, allowing for easy manual rotation of the drive wheel 200. The rotating rod 230 is connected to the drive wheel 200 via a fixed seat 231. The fixed seat 231 is fitted with an elastic element 2311, which is a helical spring, that abuts against the rotating rod 230. When the rotating rod 230 is rotated, the elastic element 2311 provides cushioning against the fixed seat 231, thus preventing excessive force from causing friction damage between the rotating rod 230 and the fixed seat 231.

[0033] Specifically, the working principle of this grounding resistance meter measuring wire reel is as follows: When in use, hold the handle 110 with one hand and rotate the rotating rod 230 with the other hand, so that its drive wheel 200 can rotate on the handle shaft 100. Then, under the action of the guide frame 300, the two measuring wires can be sequentially distributed and wound up on the first winding position 210 and the second winding position 220, realizing the simultaneous and synchronous winding and unwinding of the measuring wires. This reduces the probability of the measuring wires being twisted or broken, improves the service life of the grounding resistance measuring wires, and shortens the time required to measure the grounding resistance of each tower.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
