Description

However, due to environmental factors, human damage or natural aging, high-voltage cables are often damaged, which not only affects the normal transmission of electricity, but also may pose a threat to personnel safety. Therefore, quickly and accurately locating the damaged parts of high-voltage cables has become an urgent problem to be solved in the power industry. In the existing technology, through the integrated detection device (combined with the image data collected by the high-definition camera and infrared thermal imager), the self-propelled mobile platform and the intelligent analysis system, it is possible to automatically patrol along the high-voltage cable and monitor the cable operation status in real time. When the cable is found to be damaged, the device can quickly lock the damaged location and send the location information to the operation and maintenance personnel through the wireless communication module so that they can take timely measures to repair it.

DETAILED DESCRIPTION

[0018] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1-3 The present invention provides a self-propelled high-voltage cable damage location positioning device, comprising a walking mechanism 1, a damage detection device 2 is installed on the top of the walking mechanism 1, and is characterized in that: a damage location device 4 is installed at the bottom of the walking mechanism 1, and a battery 3 is arranged on the top of the walking mechanism 1, and the battery 3 is used to power the walking mechanism 1, the damage detection device 2, and the damage location device 4; The damage positioning device 4 includes a storage box 41, and a plurality of hook positioning members 42 are stored inside the storage box 41.

By setting the positioning bar 43, the hook positioning piece 42 can be stabilized to prevent the hook positioning piece 42 from tipping over inside the storage box 41. When the hook positioning piece 42 is pushed up, it moves up at the gap between one end of the positioning bar 43 and one side of the inner wall of the storage box 41 to prevent the positioning bar 43 from restricting the upward movement of the hook positioning piece 42.

[0021] Reference Figure 4 The vertical pushing mechanism 45 includes an electric cylinder 451, which is fixedly connected to the side wall of the storage box 41. The output end of the electric cylinder 451 is fixedly connected to a vertical rod 453 through a connecting plate 452.

The output shaft of the electric cylinder 451 retracts to drive the vertical rod 453 to move upward, and the vertical rod 453 can push the hook positioning member 42 upward to make it move upward.

[0022] Reference Figure 4There are two vertical pushing mechanisms 45, which are installed on the front and back sides of the storage box 41 respectively. Two notches are set at the bottom of the hook positioning member 42, and the two notches are respectively adapted to the vertical rods 453 of the two vertical pushing mechanisms 45. When the two vertical pushing mechanisms 45 are output during use, the top of the vertical rod 453 is embedded in the bottom notch of the hook positioning member 42, thereby preventing the hook positioning member 42 from tilting or tipping over during the ejection process.

[0023] Reference Figure 5 The horizontal pushing mechanism 44 includes a horizontal arm 441, one end of which is fixedly connected to one end of the inner wall of the storage box 41, and an axial hole is opened inside the horizontal arm 441, and a threaded rod 442 is movably sleeved in the axial hole. The side wall of the horizontal arm 441 is opened with a sliding groove connected to the axial hole, and a sleeve 443 is threadedly sleeved on the side wall of the threaded rod 442. A horizontal pushing plate 444 is arranged on the outside of the horizontal arm 441, and a protrusion is arranged on the side wall of the horizontal pushing plate 444, and the protrusion passes through the sliding groove of the horizontal arm 441 and is connected with the sleeve 443. One side of the horizontal pushing plate 444 abuts against the hook positioning member 42, and a motor 445 is installed on the outside of the storage box 41. The output shaft of the motor 445 passes through the storage box 41, the horizontal arm 441 is connected with the threaded rod 442, and when in use, the threaded rod 442 is driven to rotate by the output power of the motor 445, and the sleeve 443 is moved under the influence of the threaded structure, and the horizontal pushing plate 444 is driven to move by the sleeve 443 to achieve the effect of horizontally pushing the hook positioning member 42.

[0024] Reference Figure 6 The hooking and positioning member 42 includes a U-shaped frame 421. The two vertical tops of the U-shaped frame 421 are both provided with arm grooves. The two arm grooves are fixedly connected with fixed columns 422. The side walls of the two fixed columns 422 are movably sleeved with hanging arms 423. The side walls of the two hanging arms 423 are respectively connected to the inner walls of the arm grooves through two torsion springs 424. The inner walls of the hanging arms 423 are fixedly connected with sliders 429. The side walls of the torsion springs 424 are provided with arc grooves. The sliders 429 are slidably sleeved in the arc grooves. When the hooking and positioning member 42 moves up and contacts the cable, First, the two hanging arms 423 are pressed against the cable. At this time, the two hanging arms 423 are pressed and flipped downward and hidden in the arm groove until the cable enters the inner cavity of the U-shaped frame 421 and is no longer in contact with the hanging arms 423. Under the torsion effect of the two torsion springs 424, the two hanging arms 423 are flipped up to restore their positions. The slider 429 cooperates with the arc groove on the side wall of the torsion spring 424 to limit the flipping angle of the two hanging arms 423, ensuring that the two hanging arms 423 can be hung on the cable, thereby making the hook positioning member 42 contact with the cable to achieve an automatic hanging effect.

[0025] Reference Figure 6 The two hanging arms 423 are in a horizontal state, and there is a gap at their inner ends. This arrangement can avoid interference between the hook positioning member 42 and the hanger 46, and the hanger 46 can reach the top of the storage box 41 through the gap between the two hanging arms 423.

The bottom end of the moving column 425 is fixedly connected to an end plate 426, which is transmission-connected to the bottom of the U-shaped frame 421 through a tension spring 427. A ribbon 428 is fixedly connected to the bottom of the end plate 426. The tension of the tension spring 427 can make the end plate 426 drive the moving column 425 to move up, so that the moving column 425 is pressed against the bottom of the cable. Since the two hanging arms 423 are suspended on the cable, the moving column 425 and the hanging arm 423 cooperate to clamp the cable, thereby avoiding displacement of the hook positioning member 42 on the cable, resulting in inaccurate positioning of the damaged position. The tension spring 427 can achieve a striking effect, which is convenient for maintenance personnel to find the position.

A reduction motor 114 is installed on the front of the U-shaped plate 111. The output end of the reduction motor 114 passes through the U-shaped plate 111 and is connected to a V-shaped wheel 112. A top platform 115 is installed on the top of the U-shaped plate 111; the bottom fixed frame 12 includes two frame plates 121, and the inner walls of the two frame plates 121 are movably sleeved with V-shaped wheels 122 at both ends.

When the moving platform 11 and the bottom fixed frame 12 are installed, the V-shaped wheels 1 112 cooperate with the V-shaped wheels 2 122 to clamp the cable, so that the walking mechanism 1 is installed on the cable, and the V-shaped wheels 1 112 are rotated by the reduction motor 1 114 and the transmission effect of the transmission mechanism 113, so that the walking mechanism 1 can walk on the cable.

[0028] Reference Fig.10 , 11The steering assembly 13 includes two fixed plates 131, and the inner sides of the two fixed plates 131 are movably sleeved with a swivel 132, and the side wall of the swivel 132 is fixedly connected with a plurality of steering wheels 133. A reduction motor 134 is installed on one side of the fixed plate 131, and the output shaft of the reduction motor 134 passes through the fixed plate 131 and is connected with the swivel 132. The side wall of the steering wheel 133 is provided with a plurality of wheel grooves along the cable axial direction. The plurality of wheel grooves are movably sleeved with rollers 135. When in use, it is necessary to ensure that the plurality of steering wheels 133 are in contact with the side wall of the cable, and the movable swivel 132 is driven to rotate by the reduction motor 134, and the plurality of steering wheels 133 are driven to rotate by the swivel 132. Under the influence of friction, the steering wheel 133 can roll along the cable axis to achieve a surrounding effect, thereby driving the entire device to surround along the cable axis. By setting the roller 135, when the device walks on the cable, the roller 135 contacts the side wall of the cable and rolls, thereby avoiding that the steering assembly 13 causes a large friction resistance to the position of the walking mechanism 1.

[0029] The working principle of the present invention is as follows: after the walking mechanism 1 is installed on the cable, the walking mechanism 1 is driven to move on the cable by the moving platform 11, and the cable damage detection is performed by the battery 3, and the walking mechanism 1 can be made to circle along the cable by the operation of the turning component 13, so as to facilitate the all-round detection of the cable and avoid the omission of the detection of the cable damage due to the occurrence of the detection blind spot; When a damaged cable is detected, a single hooking positioning piece 42 inside the storage box 41 is pushed upward by the vertical pushing mechanism 45 to move it up until the hooking positioning piece 42 contacts the cable and is automatically suspended, thereby marking the damaged position through the hooking positioning piece 42, thereby locating the damaged part of the cable, making it easier for maintenance personnel to detect it from a distance, and then the horizontal pushing mechanism 44 is used to push several hooking positioning pieces 42 horizontally as a whole, thereby filling the position of the hooking positioning piece 42 that was ejected.
