[0002] The present application relates to the technical field of electric power grids, and in particular to a cable fault detection device. Background Art

[0003] The cable fault detection device is a device specially designed to detect cable faults in power systems. In the power transmission and distribution system, cables are key components for transmitting electric energy, but due to various reasons, cables may have insulation damage, short circuits, ground faults and other problems, affecting the normal operation of the power system. The main function of the cable fault detection device is to locate cable faults in a timely and accurate manner through precise measurement and analysis, thereby improving the reliability and stability of the power grid; the cable fault detection device usually uses high-precision current and voltage sensors to monitor the current and voltage waveforms in the cable in real time; by analyzing the parameters in the cable, it can quickly determine whether the cable has a fault; for example, when a short circuit occurs in the cable, the current waveform will change abnormally, and the cable fault detection device can accurately identify and locate the fault point; the cable fault detection device uses advanced signal processing and data analysis technology to conduct a comprehensive diagnosis of the cable system. This includes monitoring of multiple aspects such as cable length, insulation resistance, and conductor connection status to comprehensively judge the health of the cable. Through these detailed analyses, the specific location of the cable fault can be found more accurately, providing a strong basis for subsequent maintenance and processing; however, the cable fault detection device is generally installed on the overhead cable and exposed to the outside. In heavy snow weather, snowflakes accumulate on the abnormal indicating element and freeze, which can easily cause damage to the abnormal indicating element. The existing technology cannot prevent the accumulation of snowflakes by generating vibrations by clapping. To address this problem, we need to take timely solutions to ensure the normal operation of the abnormal indicating element. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Refer to the attached specification Figure 1-7 A cable fault detection device according to an embodiment of the present invention comprises a device base 1 and a snow collision mechanism 2, wherein the device base 1 comprises an abnormal indication element 101, a trigger carrier plate 102 is fixedly mounted on the top of the abnormal indication element 101, a rotary base 103 is rotatably connected to the inner side of the trigger carrier plate 102, a rotary cylinder A105 is fixedly mounted on the top of the rotary base 103, a spiral spring coil A106 is arranged on the inner side of the rotary cylinder A105, and a linkage rope A107 is fixedly connected to one end of the spiral spring coil A106; a rotary snow removal panel 104 is bonded to the outer side of the rotary base 103, the rotary snow removal panel 104 is arranged in a conical shape, and the rotary snow removal panel 104 and the trigger carrier plate 102 are arranged in a close fit;

[0023] like Figure 4 As shown, one end of the linkage rope A107 is wound around a rotating cylinder B108, a spiral spring coil B is provided on the inner side of the rotating cylinder B108, a transverse support rod 109 is rotatably connected to the inner side of the rotating cylinder B108, a shield shell 110 is fixedly installed on one end of the transverse support rod 109, a linkage rope B111 is wound around the outer side of the rotating cylinder B108, the linkage rope A107 and the linkage rope B111 are wound in opposite directions, a spacing is provided between the linkage rope A107 and the linkage rope B111, one end of the linkage rope B111 is fixedly connected to a corresponding sliding plate 112, and the corresponding sliding plate 112 is fixedly installed on the outer side of the trigger carrier plate 102;

[0024] like Figure 4 As shown, a limited movable sliding column 113 is fixedly installed on one side of the corresponding sliding plate 112, and the limited movable sliding column 113 is slidably connected to the shield shell 110. A corresponding node A114 is fixedly installed on the outer side of the limited movable sliding column 113, and a corresponding node B115 is fixedly installed on the inner side of the shield shell 110.

[0025] It should be noted that when the device is actually used, when snowflakes accumulate on the top of the trigger carrier plate 102, the increased weight of the trigger carrier plate 102 will cause the corresponding sliding plate 112 to slide down. During the sliding process, the corresponding node A114 and the corresponding node B115 will rub against each other, thereby causing the corresponding sliding plate 112 to vibrate and shake off the snowflakes. While the corresponding sliding plate 112 is sliding down, the linkage rope B111 will drive the rotating column B108 to rotate. The length of the linkage rope B111 will increase, and the spiral spring coil B will be tightened at the same time. The rotating column B108 will wind the linkage rope A107 when rotating, causing the rotating column A105 to rotate and tighten the spiral spring coil A106 at the same time. The rotating column A105 drives the rotary snow removal when rotating. The panel 104 rotates, and the snowflakes are removed by the centrifugal force generated by the rotation of the rotary snow removal panel 104. At the same time, the friction between the rotary snow removal panel 104 and the trigger carrier plate 102 generates heat, thereby preventing the snowflakes from remaining. After the snowflakes are removed, the weight of the trigger carrier plate 102 is reduced, and the rebound of the spiral spring coil B drives the rotating column B108 to reversely wind the linkage rope B111, thereby driving the corresponding sliding plate 112 to rise, so that the trigger carrier plate 102 is reset. During the rising process, the rebound of the spiral spring coil A106 drives the rotating column A105 to rotate again, so that the rotary snow removal panel 104 and the trigger carrier plate 102 are rubbed and heated up, so that when the snowflakes come into contact with the trigger carrier plate 102 and the rotary snow removal panel 104, they will melt and flow out, thereby preventing the snowflakes from solidifying.

[0026] Example 2: Figure 6 As shown, the snow-collision mechanism 2 includes an inclined guide rail 201, which is fixedly installed on one side of the shield shell 110, and a corresponding sliding block 202 is slidably connected to the inner side of the inclined guide rail 201. A connecting support rod 203 is fixedly installed on one side of the corresponding sliding block 202. The connecting support rod 203 is slidably connected to the inner side of the shield shell 110, and a stable positioning plate 204 is fixedly installed on one end of the connecting support rod 203. A curved body A205 is hinged on one side of the stable positioning plate 204, and a position limiting column 206 is fixedly installed on the bottom of the stable positioning plate 204. The position limiting column 206 is attached to the bottom of the rotating column A105, and a curved body B207 is fixedly installed on one side of the corresponding sliding plate 112. The curved body B207 and the curved body A205 are arranged in the same vertical plane.

[0027] like Figure 6As shown, a hollow support structure 208 is fixedly installed on the top of the inclined guide rail 201, and a cylindrical hole is opened inside the hollow support structure 208. A spherical impact member 209 is arranged in the cylindrical hole of the hollow support structure 208. The spherical impact member 209 is arranged in a close fit with the corresponding sliding block 202. A transverse structure plate 210 is fixedly installed on the side of the corresponding sliding block 202 away from the connecting support rod 203. An elastic tensioning rope 211 is sleeved on the outer side of the transverse structure plate 210. One end of the elastic tensioning rope 211 is sleeved on a movable top plate 212. The movable top plate 212 is provided on the movable top plate 212. The top plate 212 is arranged on the top of the hollow support structure 208, and the cross-sectional area of ​​the bottom end port of the movable top plate 212 is larger than the cross-sectional area of ​​the bottom end port of the cylindrical hole of the hollow support structure 208. An annular rotating seat 213 is fixedly installed at one end of the movable top plate 212, and the inner side of the annular rotating seat 213 is rotatably connected with an axial fixing rod 214, and the axial fixing rod 214 is fixedly installed on one side of the shield shell 110, and a cantilever arm rod 215 is fixedly installed on the outer side of the annular rotating seat 213, and a movable collision plate 216 is fixedly installed on the top of the cantilever arm rod 215.

[0028] It should be noted that when the device is actually used, when the corresponding sliding plate 112 slides down, the curved body B207 contacts the curved body A205, thereby pushing the curved body A205 to slide down, and the position limiting column 206 is used to limit the curved body A205, thereby preventing the curved body A205 from deflecting downward, and the corresponding sliding block 202 is guided by the inclined guide rail 201. When the corresponding sliding block 202 slides along the inside of the inclined guide rail 201, the distance between the curved body A205 and the curved body B207 will gradually increase until it is detached. When the corresponding sliding block 202 slides down, the elastic tensioning rope 211 is stretched, and when the curved body A205 is detached from the curved body B207, the elastic tensioning rope 211 rebounds and drives the corresponding sliding block 202 to slide up. The spherical impact member 209 hits the movable top plate 212 upward after being hit, so that the movable top plate 212 drives the annular rotating seat 213 to deflect. When the annular rotating seat 213 deflects, the movable collision plate 216 slaps and triggers the supporting plate 102 to generate a large vibration to prevent snowflakes from accumulating. After the slapping is completed, the elastic tensioning rope 211 is used to pull the movable top plate 212 to reset, so that the movable top plate 212 stays on the top of the hollow support structure 208 again. When the corresponding sliding plate 112 slides up, the curved body B207 contacts the curved body A205, so that the curved body A205 deflects upward, thereby leaving more space for the curved body B207 to pass through, so as not to hinder the corresponding sliding plate 112 from sliding up and resetting smoothly.

[0029] A cable fault detection method comprises the following steps:

[0030] S1: When snowflakes accumulate on the top of the trigger carrier plate 102, the weight of the trigger carrier plate 102 increases, causing the corresponding sliding plate 112 to slide down. During the sliding process, the corresponding node A114 rubs against the corresponding node B115, thereby causing the corresponding sliding plate 112 to vibrate, causing the snowflakes to be shaken off. At the same time, the linkage rope B111 drives the rotating cylinder B108 to rotate. When the rotating cylinder B108 rotates, it winds the linkage rope A107, causing the rotating cylinder A105 to rotate and drive the rotating snow removal panel 104 to rotate. The centrifugal force generated by the rotation of the rotating snow removal panel 104 is used to remove the snowflakes. At the same time, the friction between the rotating snow removal panel 104 and the trigger carrier plate 102 generates heat, thereby preventing the snowflakes from remaining.

[0031] S2: When the snowflakes are removed, the weight of the trigger carrier plate 102 is reduced, and the spiral spring coil B rebounds to drive the rotating cylinder B108 to reversely wind the linkage rope B111, thereby driving the corresponding sliding plate 112 to rise, so that the trigger carrier plate 102 is reset. During the rising process, the spiral spring coil A106 rebounds to drive the rotating cylinder A105 to rotate again, so that the rotating snow removal panel 104 and the trigger carrier plate 102 are heated by friction, so that when the snowflakes come into contact with the trigger carrier plate 102 and the rotating snow removal panel 104, they melt and flow out, thereby preventing the snowflakes from solidifying;

[0032] S3: When the corresponding sliding plate 112 slides down, the curved body B207 contacts the curved body A205, thereby pushing the curved body A205 down. The distance between the curved body A205 and the curved body B207 gradually increases until they are separated. When the corresponding sliding block 202 slides down, the elastic tension rope 211 is stretched. When the curved body A205 is separated from the curved body B207, the elastic tension rope 211 rebounds and drives the corresponding sliding block 202 to slide up and hit the spherical impact member 209. After being hit, the spherical impact member 209 hits the movable top plate 212 upward, so that the movable top plate 212 drives the annular rotating seat 213 to deflect. When the annular rotating seat 213 deflects, the movable collision plate 216 hits the triggering carrier plate 102, thereby generating a large vibration to prevent snow accumulation;

[0033] S4: After the beating is completed, the elastic tensioning rope 211 is used to pull the movable top panel 212 to reset, so that the movable top panel 212 stays on the top of the hollow support structure 208 again, and when the corresponding sliding plate 112 slides up, the curved surface body B207 contacts the curved surface body A205, so that the curved surface body A205 deflects upward, thereby leaving more space for the curved surface body B207 to pass through, so as not to hinder the corresponding sliding plate 112 from sliding up and resetting smoothly.
