Description

Technical Field

[0001] This application relates to the field of power distribution network line inspection technology, and in particular to a wire storage device. Background Technology

[0002] In power companies, staff need to perform insulation resistance tests on distribution network lines and equipment to ensure that the lines and equipment are operating at a healthy level. Due to height and location limitations of the lines, long test leads are required during actual testing to connect the test leads from the lines or equipment to the testing instruments.

[0003] After the experiment, the test line needs to be stored. The current method is to manually fold and roll it up, which is time-consuming and the test line is prone to tangling. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a wire storage device to solve the problems of low storage efficiency and easy tangling of existing test wires.

[0005] To achieve the above-mentioned technical objectives, this application provides a wire storage device, comprising: a housing, a take-up reel, and a torsion spring;

[0006] The housing is provided with a storage cavity;

[0007] The housing is provided with a first wire hole that communicates with the storage cavity;

[0008] The take-up reel is rotatably disposed within the storage cavity;

[0009] The outer periphery of the take-up reel is provided with an annular groove for the test line to be inserted;

[0010] The take-up reel is provided with a guide groove that communicates with the annular groove;

[0011] The housing is provided with a second wire hole that communicates with the guide groove;

[0012] The torsion spring is disposed inside the receiving cavity, and its two ends are respectively connected to the housing and the take-up reel.

[0013] Furthermore, the take-up reel is connected to a rotating portion extending out of the housing.

[0014] Furthermore, the receiving cavity is screw-shaped so that the test line extending from the guide groove can be guided to pass through the first wire hole.

[0015] Furthermore, it also includes guide wheels;

[0016] The guide wheel is rotatably disposed within the receiving cavity and located beside the first wire hole, for guiding the test line on the take-up wheel to the first wire hole.

[0017] Furthermore, the guide grooves include multiple grooves and are distributed circumferentially around the center of the take-up reel.

[0018] Furthermore, the take-up reel has a hollow cavity inside;

[0019] A guide block is provided inside the hollow cavity;

[0020] The guide groove is disposed on the guide block.

[0021] Furthermore, it also includes a ratchet;

[0022] A ratchet is fixedly connected to the take-up reel;

[0023] The ratchet is movably disposed within the receiving cavity;

[0024] When the ratchet bar engages with the ratchet wheel, the ratchet wheel cannot rotate in the direction of reeling in the line.

[0025] Furthermore, the housing is provided with adjustment holes;

[0026] The ratchet extends out of the housing through the adjustment hole.

[0027] Furthermore, it also includes springs;

[0032] When winding up the test line, the test line can be passed through the second hole, guided through the guide groove to the ring groove, and then wound onto the take-up reel before finally exiting through the first hole. When the line needs to be unwound, it can be pulled out directly from the first hole.

[0040] Please see Figure 1 and Figure 2 The present application provides a wire storage device, comprising: a housing 10, a take-up reel 20, and a torsion spring (not shown in the figure); a storage cavity 11 is provided inside the housing 10; a first wire hole 12 communicating with the storage cavity 11 is provided on the housing 10; the take-up reel 20 is rotatably disposed inside the storage cavity 11; an annular groove 21 for inserting test wire is provided on the outer periphery of the take-up reel 20; a guide groove 22 communicating with the annular groove 21 is provided inside the take-up reel 20; a second wire hole 13 communicating with the guide groove 22 is provided on the housing 10; and the torsion spring is disposed inside the storage cavity 11, with its two ends connected to the housing 10 and the take-up reel 20 respectively.

[0041] When preparing for the test, the staff can pass the test line through the second wire hole 13 into the guide groove 22, and guide it through the guide groove 22 to the ring groove 21, and then pass it out through the first wire hole 12. After that, the test line can be wound around the take-up reel 20 by rotating the take-up reel 20.

[0042] When the test line is extended, it can be pulled out from the first wire hole 12 to the required length for testing. During the extension of the test line, the torsion spring will store force. After the test is completed, the torsion spring can drive the take-up wheel 20 to rotate and retract the test line. Compared with the existing take-up method, it can effectively improve the take-up efficiency and the neatness of the line after take-up. It is also convenient for staff to carry and the length of the extended test line can be adjusted as needed.

[0043] In one embodiment, the housing 10 can be a detachable closed structure, with the take-up reel 20 enclosed in the storage cavity 11 of the housing 10; when threading the wire, the housing 10 can be disassembled first, so that the operator can drive the take-up reel 20 to rotate and wind the test wire.

[0044] As another implementation, the housing 10 can be an open structure, that is, the storage cavity 11 is an open cavity, so that after the test line is passed through the annular groove 21, the operator can directly rotate the take-up reel 20.

[0045] In one embodiment, the housing 10 is a closed structure, and the take-up reel 20 is connected to a rotating part 23 extending out of the housing 10; the operator drives the take-up reel 20 to rotate through the rotating part 23 outside the housing 10, thereby winding the test line onto the take-up reel 20.

[0046] Furthermore, the receiving cavity 11 is screw-shaped so that the test line extending from the guide groove 22 can be guided to pass through the first wire hole 12.

[0047] Specifically, the spiral cavity shape refers to the fact that the cavity wall of the receiving cavity 11 is in the shape of a spiral arc, so that after the test line touches the cavity wall of the receiving cavity 11, it will continue to move along the cavity wall to the first wire hole 12 and pass out.

[0048] In a further improved embodiment, a guide wheel 30 is also included; the guide wheel 30 is rotatably disposed in the receiving cavity 11 and located beside the first wire hole 12, for guiding the test line on the take-up wheel 20 to the first wire hole 12.

[0049] The guide wheel 30 is located at the position corresponding to the first wire hole 12, so that after the test line moves and comes into contact with the guide wheel 30, it can be guided by the guide wheel 30 and pass through the first wire hole 12.

[0050] In application, the guide groove 22 includes multiple grooves and is distributed circumferentially around the center of the take-up reel 20. For example, it can be evenly distributed circumferentially, so that the test line passing through the second wire hole 13 can more easily pass into the guide groove 22.

[0051] In another embodiment, the take-up reel 20 has a hollow cavity 24 inside; a guide block 25 is provided inside the hollow cavity 24; and a guide groove 22 is provided on the guide block 25.

[0052] The take-up reel 20 is provided with a wire-passing hole that connects to the guide groove 22, so that the test wire in the guide groove 22 can pass through to the annular groove 21.

[0053] In a more specific embodiment, a ratchet 40 is also included; a ratchet 26 is fixedly connected to the take-up reel 20; the ratchet 40 is movably disposed in the receiving cavity 11; when the ratchet 40 and the ratchet 26 are engaged, the ratchet 26 cannot rotate in the take-up direction.

[0054] After the test line is pulled out and the torsion spring is charged, the ratchet 40 can lock the ratchet 26, making the take-up reel 20 temporarily unable to rotate. After the test is completed, the ratchet 40 is rotated to separate the ratchet 40 from the ratchet 26, and the take-up reel 20 can then rotate freely to retrieve the test line.

[0055] Furthermore, the housing 10 is provided with an adjustment hole 14; the ratchet 40 extends out of the housing 10 through the adjustment hole 14.

[0056] Thus, the operator can control the ratchet 40 by passing the ratchet 40 through the adjustment hole 14.

[0057] Furthermore, it also includes a spring; the spring is disposed in the receiving cavity 11, with one end connected to the housing 10 and the other end connected to the ratchet 40, for providing an elastic force to the ratchet 40 to move toward the ratchet 26.

[0058] The spring allows the ratchet 40 to automatically engage with the ratchet 26.

[0059] In one embodiment, the housing 10 is provided with at least two storage cavities 11; the take-up reel 20 and the torsion spring are both included in at least two, and are installed in a one-to-one correspondence with the storage cavities 11.

[0060] That is, in this embodiment, two take-up reels 20 can be respectively provided inside the housing 10 for take-up of the line.

[0061] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although this application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
