Description

Technical Field

[0001] The present invention belongs to the technical field of lightning arrester detection, and in particular relates to a wind turbine lightning arrester detection device. The present invention also relates to the above-mentioned wind turbine lightning arrester detection method. Background Art

[0002] As wind turbines continue to grow in size, the reliability of their lightning protection systems is critical to the safe operation of the entire unit.

[0003] At present, the lightning protection system of wind turbines is mainly composed of external lightning rods and internal wires. The principle is to safely divert lightning to the ground through lightning rods and lightning conductors. However, frequent lightning diversion and rain erosion cause the surface of the lightning rods to rust, and the internal wires to break or fail. If not discovered in time, the wind turbine is very likely to be destroyed by lightning in thunderstorms.

[0004] In the past, the inspection method for wind turbine lightning protection systems was manual inspection. This method required the use of a high-altitude hanging basket to send workers to the vicinity of the lightning rod, and the workers then used a file to grind it before conducting an Ohm's method inspection. This manual method of high-altitude work is extremely dangerous, and the method of lifting the hanging basket is inefficient. The existing technology is drone inspection technology, and its mainstream includes two types: negative pressure suction cup drone inspection and Ohm's method ceiling drone inspection device.

[0005] The Ohm method ceiling-mounted drone is to install a detection net on the top. This method can only detect the lightning receptor at the tip of the blade, and the whole is bulky. After the drone flies to the designated position, it cannot be fine-tuned, and it is necessary to carry wires up, which can easily cause the drone to hover out of control. In addition, the drone rotor needs to provide upward pressure during the detection, and there is a great risk of crashing if it is not operated properly. The negative pressure suction cup type UAV detection device is a mechanical arm installed at the lower end of the UAV, with a negative suction pressure cup at the end of the arm. During detection, the arm is extended to allow the pressure cup to be adsorbed to the surface of the fan blade, and then the probe on the pressure cup is used for detection. However, in actual applications, there is a problem of poor contact in probe detection, and the designer did not take into account the instantaneous force generated by the fan vibration, which can easily cause the suction cup to fall off, resulting in detection failure; and the UAV needs to exert force for both adsorption and peeling of the suction cup, and improper operation can also easily cause the risk of collision; and when the device is operating normally, the unidirectional extension of the mechanical arm will cause the center of gravity of the UAV to shift, resulting in unstable flight.

[0006] In addition, the obvious problem with other types of drone detection devices is that the drones are operated with lines and cannot be flexibly fine-tuned after reaching the location, the lightning rods are not polished, resulting in inaccurate detection, and the operation with lines easily makes it more difficult for the drone to hover in the air. Summary of the invention

[0007] The purpose of the present invention is to provide a wind turbine lightning arrester detection device, which solves the problems in the prior art of fan vibration causing the suction cup to fall off during the lightning arrester detection process and the difficulty of hovering when the drone is carrying a line for detection.

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the wind turbine lightning arrester detection device of the present invention, the direction motor 203 in the first vector cylinder 202 rotates to control the direction gear 204 to drive the rotating gear 206 to rotate and adjust the flight direction of the UAV 1, and the power of the rotating motor 209 adjusts the flight speed of the UAV 1; the upper end rail 308 cooperates with the lower end rail 309 to fix the UAV 1 and the rotating component 3, the connecting teeth 303 are engaged with the moving gear 304, and the first motor 305 rotates to drive the UAV 1 and the rotating component 3 to rotate; the infusion hose 405 transports the cleaning liquid in the high-pressure bottle 403 to the bristles 5020 to clean the impurities in the lightning arrester.

[0023] The cam 40914 is irregular in shape. Driven by the third motor 40913, the cam 40914 rotates to drive the compression spring 40916 to compress and deform and recover, thereby realizing power generation of the piezoelectric ceramic 40915. The suction cup 5023 is connected to the air hose 4079, which is connected to the air inlet 4076. The air volume in the suction cup is controlled by the movement of the one-way valve 4075, thereby realizing the adsorption function of the suction cup 5023. The first telescopic tube 5018 and the second telescopic tube 6018 can be telescoped, thereby improving the flexibility of the device during operation. The retractable wire 4094 passes through the hollow column 6023 and is connected to the fixed boss 6024, transmitting the voltage to the cap shell 6021, and the cap 6033 contacts the lightning arrester for detection. The camera 8 transmits the captured photos to the control component 7, and the control component 7 can determine the position of the drone 1, specify the best route, and complete the control of the grinding and detection work according to the content of the photos. The retractable wire 4094 is connected to the fixed boss 6024. When the retractable wire 4094 is tightly connected to the fixed boss 6024, 6022 is in a compressed state, and the cap 6028 and the cap shell 6021 are tightly fitted and do not shake. When the retractable wire 4094 and the fixed boss 6024 are not tightly connected, a small displacement shake may occur between the cap 6028 and the cap shell 6021. The detection copper cap wire 40910 transmits the generated voltage to the cap 6033, and the lightning arrester is detected through the cap 6033 to receive the lightning. The device is concave, and the limit plate 6031 controls the tension line 6030 through the rotation of the eleventh motor 6025 to open and close, which can realize the action of clamping or loosening the lightning rod; the rust removal component 5 carried by the drone 1 can greatly improve the safety of practitioners, and most wind turbines are built in sparsely populated areas. The drone 1 can fly directly to the destination. The drone 1 is equipped with an image acquisition component camera 8, which can transmit its own position information and lightning rod information, grinding and detection working status in real time, making the cost lower and the result more reliable.

[0024] The present invention uses piezoelectric ceramic 40915 as a power source for lightning strike detection. Only staff are required to perform detection at the bottom, and there is no need for the drone to work with a line, thereby improving detection efficiency. The present invention can grind the lightning receptor on the side of the fan blade, and after the drone 1 hovers, the rust removal component 5 or the detection component 6 is in the process of docking with the lightning receptor, and the setting of the direction adjustment component 2 and the rotation component 3 can control rust removal or detection, thereby improving the flexibility of detection and rust removal. The present invention applies the drone 1 to rust removal and detection of lightning receptors on wind turbine blades for the first time. The drone 1 has a higher posture change under complex flight conditions such as vertical take-off and landing, hovering, inverted flight, and sharp turns. The surface of the fan blade is mostly arc-shaped, and the purpose of rust removal and detection without dead angles can be achieved by using the drone 1 to adjust the tilt state of the fuselage in real time.

[0025] The piezoelectric ceramic 40915 can generate instantaneous high-voltage current after being hammered. The current is guided to the ground through the lightning receptor, and the electromagnetic induction coil is used on the ground to measure the result. The whole process avoids the difficulties of UAV line operation, and the detection method of simulated lightning is similar to that of lightning strikes, making the measurement results more accurate.
