Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicle (UAV) power inspection, and in particular to a mounting device for a detection device for a transmission line. Background Art

[0002] With the increasing development of social economy and the continuous improvement of users' electricity requirements, the power industry is facing increasingly severe challenges. The stability of power transmission and distribution, and the high quality requirements of power supply and power consumption are of great importance. In the power system, high-voltage overhead transmission lines are the main arteries of regional power transmission. Due to long-term exposure to the outdoors, overhead transmission equipment is prone to abnormal conditions such as wear, broken strands, rust, overheating, and tower collapse during long-term operation. On the other hand, lightning strikes insulators, high-voltage discharge caused by tree branch contact, line insulation aging, and foreign matter coverage can also easily induce transmission line failures. Therefore, daily inspections of high-voltage overhead transmission lines are the top priority to ensure the safe, stable, and efficient operation of the power grid. Installing detection equipment on overhead lines is a new solution for overhead transmission line detection. Using drones equipped with transmission line mounting devices can efficiently and reliably realize the installation and removal of detection equipment.

[0003] Using various online equipment for testing can reduce the workload of maintenance personnel, and can also monitor and analyze the lines in real time. However, the installation and disassembly of online testing equipment is currently a difficult problem. The traditional method is that maintenance personnel install and disassemble on-site, which has great work risks and low work efficiency. Drone maintenance is the main direction for the maintenance of overhead power transmission lines in the future. At this stage, using drones as a maintenance method to realize field high-altitude maintenance has become an indispensable maintenance method for overhead power transmission lines.

[0004] In the prior art, a Chinese patent with application number CN202021640630.2 discloses a power transmission line mounting device, which consists of a carrying box, a support plate, a fastening nut, a connecting shaft, a guide wheel, a connecting rod, a lock, a rotating shaft, a limit ring, a threaded hole, and an outer part. However, the mounting device itself does not work in coordination with the drone to achieve the mounting and retrieval of the power transmission line detection equipment, and the structure is relatively complex, with the risk of damage due to too many online times. At the same time, the mounting device is inconvenient to go online, and the maintenance personnel are cumbersome to operate, and it does not have the ability to work stably for a long time and multiple times.

[0005] Currently, there are two ways to inspect overhead transmission lines: manual inspection and inspection robot inspection. Manual inspection has the problems of low work efficiency, high operation risk and susceptibility to factors such as terrain and weather. Although inspection robots can improve work efficiency, they are easily affected by high voltage, causing problems such as robot malfunction and uncontrollable. Summary of the invention

[0044] As a preferred embodiment, the movable bracket 105 is rectangular, and the locking structure of the movable bracket 105 is a limiting groove 109 provided on the upper part of the movable bracket 105. There are four limiting grooves 109, which are respectively provided on the four side surfaces of the upper part of the movable bracket 105. At the same time, the locking structure of the sliding bracket 204 is an arc-shaped buckle 208 provided on the top of the sliding bracket 204. There are four arc-shaped buckles 208, which are respectively matched with the four limiting grooves 109, and the arc-shaped buckles 208 are used to prevent the sliding bracket 204 from slipping off from the movable bracket 105.

[0045] In this embodiment, a button 103 is provided on the movable bracket 105, and the button includes a button cover, and a spring limiting hole is provided in the button cover, and a spring is connected to the spring limiting hole, and the other end of the spring is connected to a fixing column 108;

[0046] The button 103 is also provided with a positioning pin 101, a fixing block 102, a wedge block 104 and a button wedge block 107;

[0047] The button 103 is provided with two button wedges 107, which are respectively installed on the inner side of the button cover, and a wedge 104 is installed between the two button wedges 107;

[0060] (2) Determine that the target line is below the drone through visual positioning, and determine the distance between the target line and the rotor through ranging. The drone falls along the Z direction. The pilot ensures the accuracy of the rotor position through visual observation or the assistance of another drone.

[0061] (3) After determining the target line position, the transmission line slides into the groove of the fixed bracket through the rotating wheel. After the fixed bracket and the transmission line are fixed in relative position, the UAV drives the movable bracket to move downward, and the hatch on the lower side of the movable bracket clamps the rotating wheel. At the same time, the positioning pin passes through the positioning hole of the sliding bracket to ensure that the movable bracket and the sliding bracket are relatively fixed, thereby ensuring that the entire device is fixed on the transmission line;

[0062] (4) The drone disconnects from the connected component and flies away from the scene.

[0063] When retrieving the mounting device from the power transmission line, this embodiment provides a preferred installation method embodiment, which mainly includes the following steps:

[0064] (1) The UAV flies to about 2.5 meters above the target line and determines through visual positioning that the target line is below the UAV;

[0065] (2) Using the distance measuring equipment, determine the distance between the target line and the operable range of the rotating wheel. The UAV falls in the Z direction. The pilot then ensures the accuracy of the mounting device's rotating wheel position by visual inspection or with the assistance of another UAV.

[0066] (3) The drone is connected to the connecting component at the top of the fixed and movable brackets, and uses its own mechanical claw structure to press the buttons on both sides of the movable bracket. The spring is compressed, the positioning pin pops out of the positioning hole of the sliding bracket, and the drone drives the movable bracket to move upward. The hatch fixed on the lower side of the movable bracket moves upward at the same time. The movable bracket and the sliding bracket are connected through the limit groove and the arc buckle. The rotating wheel rotates to move the power transmission line located in the groove of the fixed bracket out;

[0067] (4) The drone carries the mounting device with the detection equipment and flies away from the scene and returns.

[0068] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
