Description

Technical Field

[0001] The utility model relates to the technical field of electric power maintenance equipment, in particular to a high-voltage power transmission line damage detection device. Background Art

[0002] With the rapid development of the power system, high-voltage transmission lines are the key link in power transmission, and their safe operation is of vital importance. However, due to environmental factors, material aging, external force damage and other reasons, high-voltage transmission lines often suffer from damage, such as broken strands, corrosion, foreign body entanglement, etc. If these damages are not detected and repaired in time, they may cause line failures and even serious safety accidents.

[0003] In order to ensure the safe operation of high-voltage transmission lines, various line detection devices are widely used in line inspection and maintenance. These detection devices usually need to be installed on the transmission cable and move along the cable to achieve comprehensive detection of the line. However, the existing line detection equipment has some shortcomings in design and use, especially in the anti-slip mechanism.

[0004] Existing line detection equipment often lacks an effective anti-detachment mechanism. During the operation of the equipment, once it encounters strong vibration, wind or other external forces, the detection equipment may fall off the cable, which will not only lead to the interruption of the detection task, but also may pose a safety threat to the personnel and facilities below. Therefore, we propose a high-voltage transmission line damage detection device to solve the above problem. Summary of the invention

Detailed implementation manners

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0026] This application provides a high-voltage transmission line damage detection device, which is mainly used to solve the problem that existing line detection devices in the prior art often lack an effective anti-disengagement mechanism. During the operation of the device, once encountering strong vibrations, wind forces, or other external forces, the detection device may fall off the cable, which will not only cause the interruption of the detection task but also pose a safety threat to the personnel and facilities below, and provides the following technical solutions. The following will be combined with Figure 1-Figure 4 make a detailed description:

[0027] A high-voltage transmission line damage detection device includes:

[0028] A base 1, on both sides of the top of which are fixedly provided H-shaped brackets 2, and on the top of the H-shaped brackets 2 is fixedly provided an installation box 3;

[0029] An auxiliary wheel 4 is arranged on the H-shaped bracket 2, and an adjusting member 5 for adjusting the height of the auxiliary wheel 4 is arranged on the H-shaped bracket 2;

[0030] Traveling wheels 6 are rotatably connected to both sides of the front of the installation box 3 through a rotating shaft;

[0031] A driving mechanism 7 is arranged inside the installation box 3 for driving the traveling wheels 6 to rotate;

[0032] A detection mechanism 8 is arranged on the front of the installation box 3 for detecting whether the cable is damaged;

[0033] The limiting mechanism 9 is arranged on both sides of the detection mechanism 8 and is used to prevent the walking wheels 6 from detaching from the cable. The limiting mechanism 9 includes a U-shaped seat 901 fixedly arranged on the front surface of the installation box 3. A rectangular notch is formed on the upper side of the U-shaped seat 901, and a movable plate 902 is hinged in the rectangular notch. A U-shaped notch 9011 is formed on the lower side of the U-shaped seat 901. A screw rod 903 is fixedly arranged at the free end of the movable plate 902. The screw rod 903 slidably penetrates through the U-shaped notch 9011, and a resisting nut 904 is threadedly connected to the end of the screw rod 903. A first limiting plate 905 is fixedly arranged in the middle of the U-shaped seat 901, and a second limiting plate 906 is fixedly arranged in the middle of the bottom of the movable plate 902. The cable penetrates between the first limiting plate 905 and the second limiting plate 906.

[0034] Workflow description:

[0035] In the first step, place the high-voltage transmission line breakage detection device on the cable to be detected, make the walking wheels 6 contact the cable, and at the same time use the limiting mechanism 9 for limiting. The specific operation is as follows: Place the cable between the first limiting plate 905 and the second limiting plate 906. Ensure that the cable is correctly installed in the gap formed by the two limiting plates. After the cable is placed, rotate the movable plate 902 so that the screw rod 903 is inserted into the U-shaped notch 9011, and then rotate the resisting nut 904 to make it抵触 the U-shaped seat 901. In this way, the cable is restricted in the space formed by the two limiting plates, which can not only keep the detection device moving along the cable but also prevent damage to the cable.

[0036] In the second step, start the driving mechanism 7 to drive the walking wheels 6 to rotate, so that the device moves along the cable. During the movement of the device, the detection mechanism 8 detects the appearance of the cable to judge whether there is a breakage.

[0037] In the third step, if a breakage is found, notify the relevant personnel in time for handling.

[0038] By setting the limiting mechanism 9, the high-voltage transmission line breakage detection device effectively avoids the device detaching from the cable, improves the stability and safety of the device. At the same time, the device has a simple structure and is easy to operate, and is applicable to various types of high-voltage transmission lines.

[0039] As Figure 3 shown, in some embodiments, the first limiting plate 905 and the second limiting plate 906 have the same specifications and are both semi-elliptical. More specifically, the semi-elliptical design enables the limiting plates to better adapt to the curved surface of the cable. When the cable is placed between the two semi-elliptical limiting plates, they jointly form a space close to a circle, which helps to better guide the cable and prevent it from shifting during movement.

[0040] As Figure 2As shown, in some embodiments, the adjustment member 5 includes an adjustment rod 501 threadedly connected to the middle part of the H-shaped bracket 2, a slider 502 is slidably connected above the inner wall of the H-shaped bracket 2, the upper end of the adjustment rod 501 is rotatably connected to the slider 502 through a bearing, and the auxiliary wheel 4 is rotatably connected to the front of the slider 502 through a rotating shaft. More specifically, when in use, the operator can rotate the adjustment rod 501, and rotating the adjustment rod 501 will cause it to rise or fall along the thread. When the adjustment rod 501 moves, the slider 502 connected thereto slides vertically above the inner wall of the H-shaped bracket 2, thereby driving the auxiliary wheel 4 to move up and down.

[0041] like Figure 4 As shown, in some embodiments, the driving mechanism 7 includes a rotating rod 701 rotatably connected between the inner side walls of the installation box 3, a motor 702 is installed on the outer wall of one side of the installation box 3, one end of the motor 702 is connected to one end of the rotating rod 701, and a driving bevel gear 703 is fixed on both sides of the rotating rod 701. The end of the walking wheel 6 located inside the installation box 3 is connected to a driven bevel gear 704, and the driving bevel gear 703 and the driven bevel gear 704 are meshed. More specifically, when the motor 702 is started, the rotating rod 701 rotates, driving the driving bevel gear 703 to rotate. When the driving bevel gear 703 rotates, its teeth are meshed with the teeth of the driven bevel gear 704, thereby driving the driven bevel gear 704 to rotate. As the driven bevel gear 704 rotates, the walking wheel 6 connected thereto also starts to rotate. By adjusting the size and number of teeth of the driving and driven bevel gears 704, the transmission ratio can be controlled, and then the rotation speed of the walking wheel 6 can be controlled to meet different detection requirements.

[0042] like Figure 2 As shown, in some embodiments, the detection mechanism 8 includes a fixed plate 801 fixed between the front side of the installation box 3 and the top of the base 1, and a mounting plate 802 is fixedly provided on the upper side of the fixed plate 801. A CCD appearance detector 803 is installed on the opposite side of the two mounting plates 802. More specifically, when the detection equipment moves along the cable, the CCD appearance detector 803 continuously scans the surface of the cable. The CCD appearance detector 803 is a high-precision image detection device, which can capture detailed images of the cable surface, has high resolution and sensitivity, and can identify minor damage, corrosion, foreign matter attachment or other potential defects on the cable. It should be noted that the CCD appearance detector 803 and the motor 702 are both prior arts, and their working principles and circuits (including power supply) are not described in detail.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
