DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] like Figure 1-Figure 6As shown, this embodiment proposes a high and low voltage wire loss detection device, including a detection box 2 sleeved on the wire 1, the detection box 2 includes an upper detection box and a lower detection box, the upper detection box and the lower detection box can be combined to form a complete detection box 2, and the upper detection box and the lower detection box are connected by bolts, so that the detection box 2 is conveniently sleeved on the wire 1, and the upper detection box and the lower detection box are respectively located on both sides of the wire 1 to clamp the wire 1 after being matched.

[0031] The detection box 2 is slidably connected to a lifting rod 22, and the lifting rod 22 is rotatably connected to a detection wheel 14 that rolls on the surface of the wire 1. The detection box 2 is slidably connected to a first recording pen 16 and a second recording pen 17. When the detection wheel 14 rises or falls, it can drive the first recording pen 16 or the second recording pen 17 to record on the paper tape 13, thereby recording defects of the wire 1.

[0032] The lifting rod 22 is provided with a large spring 23, one end of the large spring 23 is connected to the detection box 2, and the other end of the large spring 23 is connected to the lifting rod 22. Under the action of the large spring 23, the detection wheel 14 is always in contact with the surface of the wire 1. When the surface of the wire 1 is deformed, such as convex or concave, relative sliding can occur between the lifting rod 22 and the detection box 2.

[0033] The detection box 2 is slidably connected to the transmission plate 19, and the lifting rod 22 is fixedly connected to the fixed plate 21. A gap is provided between the transmission plates 19 for the fixed plate 21 to move freely. After the fixed plate 21 and the transmission plate 19 are in contact, the transmission plate 19 can be driven to move simultaneously.

[0034] The fixed plate 21 and the transmission plate 19 are staggered, and the gap distance between them is appropriate enough. When the deformation of the wire 1 is less than the threshold value, the fixed plate 21 will not contact the transmission plate 19. When the deformation of the wire 1 is large enough, the fixed plate 21 will contact the transmission plate 19, and can drive the transmission plate 19 to move simultaneously.

[0035] The second recording pen 17 is fixedly connected to the transmission plate 19, and the detection box 2 is rotatably connected to the reversing wheel 18. The two ends of the reversing wheel 18 are respectively engaged with the first recording pen 16 and the second recording pen 17. When the second recording pen 17 moves, the first recording pen 16 can be driven to move through the reversing wheel 18 to realize the recording work on the paper tape 13.

[0036] The transmission plate 19 is connected to the detection box 2 through a small spring 20. The small spring 20 and the large spring 23 are arranged in parallel. The movement directions of the transmission plate 19 and the lifting rod 22 are parallel. In the initial state, under the elastic force of the small spring 20, the distances between the first recording pen 16 and the second recording pen 17 and the paper tape 13 are equal, and the bottom surfaces of the first recording pen 16 and the second recording pen 17 are on the same horizontal plane.

[0037] The detection box 2 is rotatably connected to a paper receiving wheel 11 and a paper releasing wheel 12, the paper releasing wheel 12 is wrapped with a paper tape 13, the other end of the paper tape 13 is wrapped around the paper receiving wheel 11, the detection box 2 is fixedly connected to a bottom plate 15, the paper tape 13 is located on the bottom plate 15, the paper tape 13 and the bottom plate 15 are both located below the first recording pen 16 and the second recording pen 17, the bottom plate 15 is used to support the paper tape 13 to facilitate the recording work of the recording pen.

[0038] The detection box 2 is rotatably connected to a transmission rod 6, the transmission rod 6 is connected to a motor 5, the motor 5 and the detection box 2 are fixedly connected, the motor 5 can drive the transmission rod 6 to rotate, and the transmission rod 6 drives the paper collection wheel 11 to rotate through the first belt.

[0039] The detection box 2 is rotatably connected to a plurality of pressure rods 4, and the pressure rods 4 are rotatably connected to a running wheel 3 that rolls on the wire 1. The pressure rods 4 are connected to the detection box 2 through a torsion spring, and the transmission rod 6 drives the running wheel 3 to rotate through a second belt. Under the action of the torsion spring, the running wheel 3 can always be in contact with the wire 1 for wires 1 of different thicknesses, thereby being suitable for the use of wires 1 of different specifications.

[0040] The pressure rod 4 located on the other side is rotatably connected to the passive wheel 24. The passive wheel 24 and the walking wheel 3 are respectively located on both sides of the detection box 2. When the motor 5 drives the walking wheel 3 to rotate, the detection box 2 can be moved on the wire 1. The walking method is not affected by the length of the wire and can detect wires that are long enough.

[0041] The transmission rod 6 is fixedly sleeved with a first pulley 25 and a second pulley 26, the walking wheel 3 is fixedly connected with a third pulley, the third pulley and the first pulley 25 are sleeved with a second belt, the paper receiving wheel 11 is fixedly connected with a fourth pulley, and the fourth pulley and the second pulley 26 are sleeved with a first belt.

[0042] The detection box 2 is also slidably connected to a plurality of brackets 8, which are connected to the detection box 2 via compression springs. The brackets 8 are rotatably connected to rubber wheels 7 that roll on the wires 1. The rubber wheels 7 can walk on the wires 1, providing auxiliary support for the detection box 2, thereby facilitating subsequent detection of the wires by the detection wheels.

[0043] It also includes a detection clamp 9 clamped on the wire 1 and a detection meter 10 connected to the detection clamp 9. When the detection meter 10 detects abnormal line loss through the detection clamp 9, the detection box 2 moves along the surface of the wire 1 to detect the shape of the wire 1. The detection meter 10 and the motor 5 are connected to a control center.

[0044] A method for using a high- and low-voltage electric wire line loss detection device, using the above-mentioned high- and low-voltage electric wire line loss detection device, comprises the following steps:

[0045] S1: When the detection meter 10 detects that the line loss is abnormal, the line loss abnormality is detected according to the current of the line, the wire 1 that may have abnormal line loss is located, and the corresponding signal is transmitted to the control center, and the control center controls the motor 5 of the corresponding wire 1 to work;

[0046] S2: The motor 5 drives the transmission rod 6 to rotate, and the transmission rod 6 drives the paper receiving wheel 11 to reel in the paper tape 13. At the same time, the transmission rod 6 drives the running wheel 3 to rotate, so that the detection box 2 moves along the surface of the wire 1;

[0047] S3: When there is an abnormality in the shape of the wire 1, the bulge or depression of the wire 1 drives the detection wheel 14 to move, and the detection wheel 14 drives the fixed plate 21 to move through the lifting rod 22. After the fixed plate 21 and the transmission plate 19 come into contact, the second recording pen 17 is driven to move, and the second recording pen 17 drives the first moving pen 16 to move through the reversing wheel 18 to realize recording on the paper tape 13.

[0048] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
