Description

Technical Field

[0001] This invention relates to the field of power testing technology, and in particular to a device for inspecting the appearance of electrical wires. Background Technology

[0002] High-altitude power lines are an indispensable part of modern society, mainly used for power transmission and communication, but their operating environment is complex. Visual inspection of high-altitude power lines is difficult, as they are typically installed at high locations such as mountains, bridges, and urban steel structures. For manual inspection, workers must perform dangerous high-altitude operations, facing serious safety hazards. For example, application number CN202420009649.9 discloses a high-altitude high-voltage transmission line inspection device, including a drone body, a walking mechanism, an inspection mechanism, and a main control panel. The inspection mechanism is located below the drone body and includes an image acquisition device and an infrared thermal imager. This device performs visual inspection of high-altitude power lines through the image acquisition device; however, a single, unidirectional image acquisition camera cannot effectively perform a comprehensive visual inspection of the power lines. In harsh inspection environments, the camera lens of the image acquisition device is easily contaminated, thus affecting the progress of the power line visual inspection. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a wire appearance inspection device to more accurately resolve the problems described above.

The appearance inspection component includes a ring-shaped support body formed by connecting a main support and a secondary support. The upper end of the secondary support is hinged to one end of the main support. Four image acquisition and inspection instruments are arranged in a ring array on the outer side of the main support and the secondary support. A top frame is connected to the upper part of the main support. A transparent glass cover is provided on the inner wall of the main support and the secondary support, corresponding to the image acquisition end of the image acquisition and inspection instrument. The transparent glass cover is sealed to the outside of the image acquisition end of the image acquisition and inspection instrument. A brush holder is provided at each position of the transparent glass cover. The brush holder is provided with a brush part, and the brush part is in contact with the surface of the corresponding transparent glass cover. The brush holders are connected by connecting rods. A sliding rod is provided inside the main support at the position corresponding to both ends of the brush holder. The ends of the brush holders are slidably connected with the sliding rods. A second electrically controlled telescopic rod is fixed to the bottom outer wall of the main support. The telescopic rod end of the second electrically controlled telescopic rod is provided with a pull rod, and the pull rod is connected to the connecting rod.

[0005] Furthermore, the image acquisition end of the image acquisition and detection instrument is located inside the main support and the secondary support, and the direction of the image acquisition end of the image acquisition and detection instrument is pointing to the center of the annular support body formed by the main support and the secondary support.

[0006] Furthermore, a first electrically controlled telescopic rod is connected to the upper side of the main support. The telescopic rod of the first electrically controlled telescopic rod extends obliquely downward toward the side of the secondary support. A connecting lug is integrally formed on the outer wall of the secondary support, and the telescopic rod end of the first electrically controlled telescopic rod is connected to the connecting lug.

[0007] Furthermore, the guide of the slide rod is aligned with the axial direction of the annular support body formed by the main support and the secondary support, and the guide of the telescopic rod of the second electrically controlled telescopic rod is aligned with the guide of the slide rod.

[0008] Furthermore, the brush holder has a liquid storage chamber for storing cleaning agent inside, and a number of permeation holes are provided between the liquid storage chamber and the brush part. The brush holder has a replenishment hole that communicates with the liquid storage chamber.

[0009] Furthermore, the main support and the tie rod are provided with a hinge lug at the upper and lower positions on the same side. A roller support arm is hinged to each of the two hinge lugs. A guide roller is rotatably connected to the end of the roller support arm. The two roller support arms and the two guide rollers are arranged symmetrically upward and downward. An annular guide groove is opened on the guide roller.

[0010] Furthermore, the outer end of the pull rod is fixed with a linkage sheet metal, and a pair of curved arm pull rods are hinged on the linkage sheet metal. The pair of curved arm pull rods are respectively connected to the middle part of the roller support arm.

[0011] Furthermore, a cleaning wheel support arm is rotatably connected to the outer end of the roller support arm, and a cleaning wheel is connected to the outer end of the cleaning wheel support arm. A cleaning cotton sleeve is provided on the outside of the cleaning wheel.

[0012] Furthermore, both the shaft connected to the guide roller and the shaft connected to the cleaning wheel are provided with toothed pulleys at one end, and the guide roller and the toothed pulley connected to the shaft of the cleaning wheel are connected by a toothed belt. The middle part of the roller support arm and the middle part of the cleaning wheel support arm are provided with spring connecting supports, and a pressure spring is connected between the spring connecting supports provided in the middle parts of the roller support arm and the middle part of the cleaning wheel support arm.

[0013] The beneficial effects of this invention are: 1. This invention combines the use of a drone to transport the wire to be inspected to the location of the wire. By controlling the extension of the telescopic rod of the first electrically controlled telescopic member, the secondary support is rotated, and the secondary support and the main support open an opening, allowing the wire to enter the middle of the main support and the secondary support along the opening. Then, the telescopic rod of the first electrically controlled telescopic member is retracted, causing the secondary support and the main support to close again. With the help of the drone, the invention moves along the wire, so that four image acquisition and inspection instruments can collect and inspect the appearance of the wire in different directions. Furthermore, a transparent glass cover is provided on the outside of the image acquisition end of the image acquisition and inspection instrument to prevent dust and impurities in the external environment from contaminating the lens of the image acquisition end of the image acquisition and inspection instrument. 2. This invention periodically controls the extension and retraction of the telescopic rod of the second electrically controlled telescopic rod. The connecting rod is pulled by the pull rod. Under the guidance of the slide rod, the brush bracket is used to wipe and clean the surface of the corresponding transparent glass cover. The brush bracket is provided with a liquid storage chamber for storing cleaning agent. The cleaning agent wets the brush part through the permeation hole, thereby improving the cleaning effect of the brush part on the surface of the transparent glass cover. 3. In this invention, after the wire to be tested enters the annular support body composed of the main support and the secondary support, the second electrically controlled telescopic rod pulls the pull rod, so that the linkage sheet metal pulls a pair of roller support arms through the curved arm pull rod. The pair of wire rollers clamp the wire to be tested, which is used to guide the invention along the wire to be tested and ensure the accuracy of image acquisition of the image acquisition and detection instrument. 4. In the process of traveling on the wire, the wire roller contacts and rolls with the wire. When the wire roller rolls, it drives the cleaning wheel to rotate through the transmission of the toothed belt. The cleaning cotton sleeve on the cleaning wheel wipes and cleans the dust and impurities on the wire, thereby improving the accuracy of the image acquisition and detection instrument in acquiring visual data of the wire.

The cleaning agent wets the brush part 1061 through the penetration holes 1065, thereby improving the cleaning effect of the brush part 1061 on the surface of the transparent glass cover 105. The brush holder 106 has a replenishment hole 1066 that communicates with the liquid storage chamber 1064. The replenishment hole 1066 is used to fill the liquid storage chamber 1064 with cleaning agent before testing.

[0023] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: The present invention periodically controls the extension and retraction of the telescopic rod of the second electrically controlled telescopic rod 107, and the connecting rod 1062 is pulled by the pull rod 1071. Under the guidance of the slide rod 1063, the brush bracket 106 causes the brush part 1061 provided on the brush bracket 106 to wipe and clean the surface of the corresponding transparent glass cover 105. The brush bracket 106 is provided with a liquid storage chamber 1064 for storing cleaning agent. The cleaning agent wets the brush part 1061 through the permeation hole 1065, thereby improving the cleaning effect of the brush part 1061 on the surface of the transparent glass cover 105. Example 3

[0024] On the same side as the main support 101 and the tie rod 1071, there is a hinge lug 1011 at the upper and lower positions. A roller support arm 108 is hinged to each of the two hinge lugs 1011. A guide roller 1081 is rotatably connected to the end of each roller support arm 108. The two roller support arms 108 and the two guide rollers 1081 are arranged symmetrically upwards and downwards. An annular guide groove is formed on the guide roller 1081. A linkage plate is fixed to the outer end of the tie rod 1071. A pair of curved arm pull rods 1082 are hinged to the sheet metal 1072. The pair of curved arm pull rods 1082 are respectively connected to the middle of the roller support arm 108. When the second electrically controlled telescopic rod 107 pulls the pull rod 1071, the sheet metal 1072 pulls the pair of roller support arms 108 through the curved arm pull rods 1082, so that the pair of wire rollers 1081 clamp the wire to be tested, which is used to guide the present invention along the wire to be tested.

[0025] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: After the wire to be tested enters the annular support body composed of the main support 101 and the secondary support 102, the second electrically controlled telescopic rod 107 pulls the pull rod 1071, so that the linkage sheet metal 1072 pulls a pair of roller support arms 108 through the curved arm pull rod 1082, and a pair of wire rollers 1081 clamp the wire to be tested, which is used to guide the present invention along the wire to be tested and ensure the accuracy of image acquisition by the image acquisition and detection instrument 103.
