[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The device for detecting cable faults provides a technical solution:

[0024] The first embodiment includes a support frame 1, a controller 6 and a power supply box 2 fixed at the bottom of the support frame 1. The support frame 1 is also provided with a clamping assembly 5 for clamping the device onto the surface of the cable. The front of the support frame 1 is provided with two detectors 7, one above the other. The support frame 1 is also provided with a drive wheel assembly 8 for driving the device to move. The support frame 1 is also provided with a de-icing assembly 3.

[0025] The de-icing assembly 3 includes a support wheel 32 and a hot air blower 36. When de-icing the cable surface, the hot air blower 36 is started and hot air is sent into the support wheel 32 to melt the ice layer on the cable surface. The inner wall of the support wheel 32 is rotatably connected to a middle rod 34, and multiple fan blades 35 are fixedly connected at equal intervals on the surface of the middle rod 34. Hot air blows onto the fan blades 35, causing the multiple fan blades 35 to rotate so that the hot air is blown evenly onto the cable surface.

[0026] The de-icing assembly 3 also includes a hollow rotating rod 31, which is rotatably connected to the front of the support frame 1. A support wheel 32 is fixedly connected to one end of the hollow rotating rod 31 located in front of the support frame 1. The support wheel 32 is hollow inside, and the hollow rotating rod 31 and the support wheel 32 are in a communication state. Multiple air outlets 33 are evenly opened on the surface of the support wheel 32. A hot air blower 36 is fixedly connected to the back of the support frame 1. An air supply pipe 37 is fixedly connected to the air outlet of the hot air blower 36, and one end of the air supply pipe 37 is fixedly connected to the back of the support frame 1. The air supply pipe 37 is in a communication state with the hollow rotating rod 31. A drain outlet 38 is opened on the top of the support frame 1. A water baffle 39 is fixedly connected to the front of the support frame 1. Two water baffles 39 are located on the left and right sides of the support wheel 32, respectively, and the water baffles 39 extend from the drain outlet 38 to the bottom of the support frame 1.

[0027] When there is ice on the cable surface, the hot air blower 36 is started to blow hot air from the support wheel 32 onto the cable surface to remove ice, ensuring that the detection device can perform detection normally. The water from the melting ice is discharged from the drain 38 and is prevented from being blown into the electronic components in the device by the baffle 39, which improves the practicality of the device during use.

[0028] The second embodiment differs from the first embodiment in that: two support and stabilizing components 4 are arranged symmetrically on the left and right sides of the support frame 1. The support and stabilizing components 4 include an L-shaped plate 41, which is fixedly connected to the back of the support frame 1. A connecting rod 42 is fixedly connected to the front of the L-shaped plate 41, and a U-shaped seat 43 is rotatably connected to the surface of the connecting rod 42. A pressure roller 44 is rotatably connected inside the U-shaped seat 43. A torsion spring 45 is sleeved on the surface of the connecting rod 42 between the L-shaped plate 41 and the U-shaped seat 43. One end of the torsion spring 45 is fixedly connected to the U-shaped seat 43, and the other end of the torsion spring 45 is fixedly connected to the surface of the connecting rod 42.

[0029] A staggered and symmetrical support and stabilizing component 4 is set on both sides of the device, and the stability of the device when moving on the cable surface is improved by the staggered clamping of two pressure rollers 44.

[0030] In use, the cable is positioned between the clamping assembly 5 and the support wheel 32, and the device is clamped to the cable surface by the clamping assembly 5. At this time, the two pressure rollers 44 on the left and right are positioned above and below the cable, respectively, so as to stabilize the entire structure. In addition, when there is ice on the cable surface, the hot air fan 36 is started, and hot air is introduced into the support wheel 32 through the air supply pipe 37. After the hot air enters the support wheel 32, it comes into contact with the fan blades 35, thereby driving multiple fan blades 35 to rotate, so that the hot air is blown out evenly from multiple air outlets 33, thereby de-icing the cable surface when the device moves. The water produced by the melting ice is discharged from the drain outlet 38 under the action of the two baffles 39.
