Description

Technical Field

[0001] The present invention relates to the field of power system equipment, and particularly to a fault location and inspection device for transmission lines. Background Art

[0002] The traditional manual inspection mode of transmission lines exposes problems such as low efficiency and high risks. Therefore, the development of power inspection towards automation and intelligence is an inevitable trend. Currently, the device suitable for transmission line inspection is the unmanned aerial vehicle (UAV). UAV inspection not only has high efficiency and low risks, but also can achieve automated and intelligent operations, greatly improving the reliability of power grid operation and ensuring the safe operation of the power grid. In order to improve the inspection efficiency of UAVs, the flight route also needs to be reasonably planned. A straight inspection route will result in dead corners on both sides of the transmission line, and a reciprocating inspection route will increase the inspection time and reduce the inspection efficiency, and also has higher requirements for the performance of UAVs. Summary of the Invention

[0003] The object of the present invention is to provide a fault location and inspection device for transmission lines. The device uses a zigzag inspection route to more comprehensively cover the equipment on the transmission line with a shorter inspection route, improving the inspection efficiency. Cameras are installed around the inspection UAV to increase the shooting range of the UAV and improve the accuracy of inspection.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A fault location and inspection device for transmission lines. Base stations are set at both ends of the inspection line. The inspection route between the two base stations is in a zigzag form. There are several inspection UAVs in the base stations. The inspection UAV includes a UAV body. A control box is arranged at the bottom of the UAV body. An installation frame is arranged at the bottom of the control box. Cameras are installed on the front, rear, left, and right of the installation frame. A control module, a flight module, an image acquisition module, a storage module, and a communication module are arranged in the control box. The control module collects and processes data and signals. The flight module includes a positioning module and an automatic flight module. The automatic flight module controls the flight route of the inspection UAV, and the positioning module determines the position of the inspection UAV. The image acquisition module includes a normal image storage module and an image automatic acquisition module. The normal image storage module stores the states of each device under normal conditions. The image automatic acquisition module is responsible for photographing the equipment on the line when the inspection UAV is flying. The control module is responsible for comparing the real-time state of the equipment with the normal state. The storage module can store the inspection data of the inspection UAV. The communication module can be docked with the base stations at both ends to monitor the inspection UAV.

[0005] Optionally, a rotating motor is arranged at the central position of the bottom of the control box, and a manual camera is arranged at the output end of the rotating motor.

[0006] Optionally, the flight module further includes a manual flight module. When the data of the image automatic acquisition module is different from the data of the normal image storage module, the inspection UAV switches to the hover state and waits for the staff to intervene for manual operation. The image acquisition module further includes an image manual acquisition module. After the staff intervenes, the manual camera is controlled to further inspect the abnormal equipment.

[0007] Optionally, a placement groove is provided at the bottom of the control box. The rotary motor and the manual camera are arranged in the placement groove, and a telescopic cylinder is arranged between the rotary motor and the top of the placement groove.

[0008] Optionally, landing legs are provided at the bottom of the control box.

[0009] Optionally, the inspection routes for round trips between two base stations are symmetrically arranged.

[0010] The power transmission line fault location and inspection device of the present invention has the following advantages: (1) The inspection route in the form of a broken line cooperates with the cameras around the inspection UAV, enabling the inspection UAV to perform a full-round inspection of the equipment during a one-way flight, reducing the flight distance of the inspection UAV, lowering the flight intensity of the inspection UAV, and thus reducing the failure rate of the inspection UAV.

[0011] (2) When a problem is found, the staff intervenes in a timely manner and further inspects the equipment by controlling the manual camera, improving the inspection quality and dealing with abnormal situations in a timely manner.

[0012] (3) In the case where the manual camera does not need to intervene, the placement groove can protect the manual camera. Brief Description of the Drawings

[0018] The present invention will be further described below with reference to the drawings.

[0019] As Figures 1 - 5As shown in the figure, a power transmission line fault location and inspection device is provided with base stations 1 at both ends of the inspection line. There are several inspection drones arranged inside the base stations 1. The inspection route 11 between the two base stations 1 is in a zigzag form. The zigzag form enables the inspection drones to inspect all the equipment on the power transmission line during a one-way flight, improving the inspection efficiency. The inspection routes 11 for the round trip between the two base stations 1 are symmetrically arranged, so that the inspection drones can further inspect the equipment during the return journey, improving the inspection quality.

[0020] The inspection drone includes a drone body 2. A control box 3 is arranged at the bottom of the drone body 2. An installation frame 4 is arranged at the bottom of the control box 3. Cameras 5 are installed on the front, back, left and right of the installation frame 4, increasing the camera range of the inspection drone. A placement groove 6 is arranged at the bottom of the control box 3. A telescopic cylinder 7 is arranged in the placement groove 6. A rotary motor 8 is installed at the bottom of the telescopic cylinder 7. A manual camera 9 is arranged at the output end of the rotary motor 8. Under normal circumstances, the manual camera 9 is located inside the placement groove 6 and is in a protected state. When the manual camera 9 needs to intervene, the telescopic cylinder 7 pushes the manual camera 9 out of the placement groove 6, and the rotary motor 8 can drive the manual camera 9 to rotate 360°, for further inspection of abnormal equipment. A number of landing legs 10 are also symmetrically arranged at the bottom of the control box 3, keeping the inspection drone stable before takeoff and landing.

[0021] A control module, a flight module, an image acquisition module, a storage module and a communication module are arranged inside the control box 3. The control module centrally collects and processes data and signals. The flight module includes a positioning module, an automatic flight module and a manual flight module. The automatic flight module controls the flight route of the inspection drone. The positioning module determines the real-time position of the inspection drone. When an abnormal situation is found, the inspection drone maintains a hovering state and switches to the manual flight module. The image acquisition module includes a normal image storage module, an image automatic acquisition module and an image manual acquisition module. The normal image storage module stores the states of various equipment under normal conditions. The image automatic acquisition module is responsible for taking pictures of the equipment on the line when the inspection drone is flying. The control module is responsible for comparing the real-time state of the equipment with the normal state. When an abnormality is found, the staff intervenes and controls the manual camera 9 through the image manual acquisition module to further inspect the abnormal equipment. The storage module can store the inspection data of the inspection drone. The communication module can be docked with the base stations 1 at both ends to monitor the inspection drone.

[0022] Under normal circumstances, the inspection UAV flies from one base station 1 to another along the inspection route 11 to inspect the power transmission line between the two base stations 1. The cameras 5 installed on the inspection UAV are used to photograph the equipment along the way. The controller compares the real-time data captured with the normal data stored. If there is no abnormality, the inspection UAV continues to fly. If an abnormality occurs, the inspection UAV hovers at the current position and waits for the staff to intervene. After the staff intervenes, the UAV switches to manual operation. The staff releases the manual camera 9 and operates the inspection UAV to fly to the abnormal position. The abnormal equipment is further inspected through the manual camera 9 to confirm or eliminate the fault. After the inspection is completed, the inspection UAV flies to the inspection route 11 and continues to complete the automatic inspection. A shorter inspection route 11 covers more comprehensive equipment, reducing the flight intensity of the inspection UAV, improving the inspection efficiency, and being able to intervene in a timely manner when an abnormality is found, respond quickly, accurately locate the abnormal equipment and conduct troubleshooting, thus improving the inspection quality.

[0023] Optionally, the flight module further includes that when the data of the image automatic acquisition module is different from the data of the normal image storage module, the inspection UAV switches to the hovering state and waits for the staff to intervene in the manual operation. The image acquisition module further includes that after the staff intervenes, the manual camera 9 is controlled to further inspect the equipment with abnormalities.

[0024] The embodiments described above are only partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
