Description

Technical Field

[0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular to a wind power generation inspection unmanned aerial vehicle. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. It is a clean and renewable energy source that is increasingly valued by countries around the world. The device required for wind power generation is called a wind turbine. This type of wind turbine can be roughly divided into three parts: the wind rotor, the generator, and the tower. During the installation and use of wind turbines, they need to be inspected frequently, and wind turbine inspection plays an important role in the wind power maintenance process. Regular assessment of the health status of wind turbines and real-time monitoring of the operating status of wind turbines are an indispensable part of this process. Among them, it is particularly important to check the dust pollution on the surface of the wind turbine equipment and whether the surface anti-corrosion layer is cracked or falling off.

[0003] The existing Chinese patent with publication number CN117104555A is a power inspection UAV, including a cleaning component and a camera component arranged on the same side of the UAV body; the cleaning component includes a first connecting seat connected to an electric telescopic rod and a cleaning ring, and a motor drives the electric telescopic rod and drives the first connecting seat and the cleaning ring to move relative to the camera assembly; the cleaning ring is located on the periphery of the camera assembly and a plurality of air jets are provided on its inner surface, and a blower transmits gas to the air jets. The cleaning ring moves with the electric telescopic rod to the position of the camera, and the gas ejected from the air jets is used to clean the camera assembly. In this solution, when the picture taken by the camera assembly is blurred, the electric telescopic rod is used to make the cleaning ring and the camera body at the same height, and the blower is used to eject the air through the air jets to clean the camera body, thereby ensuring the clarity of the picture taken by the camera body; when cleaning is not required, the cleaning ring and the lens of the camera assembly are misaligned to avoid affecting the shooting of the camera assembly;

The blower transmits gas to the air jets, and the cleaning ring moves with the electric telescopic rod to the position of the camera, and uses the gas ejected from the air jets to clean the camera component; the clarity of the picture taken by the camera body is ensured; however, during the inspection of wind turbine equipment, the drone carries a camera to inspect the wind turbine equipment at high altitude. During the inspection, there is the influence of wind at high altitude, which makes it difficult for the drone to maintain stability and shake, and then drives the camera component to shake synchronously, resulting in fluctuations in the acquired picture, which in turn affects the staff's judgment on the detection results.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figure 1 to Figure 2 As shown, a wind power generation inspection drone according to an embodiment of the present invention comprises a housing 1, a camera 11 is arranged on the top of the housing 1, and a plurality of fan blade assemblies are arranged on the side of the housing 1;

[0034] A receiving plate 2 is provided at the bottom end of the housing 1, and a pair of adsorption components are symmetrically provided on both sides of the receiving plate 2; the adsorption components can be adsorbed to the surface of the wind turbine equipment to limit and stabilize the drone;

[0035] When inspecting wind turbine equipment by drone, the drone carries a camera to inspect the high-altitude wind turbine equipment. During the inspection, there is wind at high altitude, which makes it difficult for the drone to remain stable and shake, which in turn drives the camera component to shake synchronously, resulting in fluctuations in the acquired image, which in turn affects the staff's judgment on the detection results. To solve the above problem, an adsorption component is provided in an embodiment of the present invention. When in use, the staff controls the fan blade component of the drone to start, driving the casing 1 and the camera 11 to inspect the high-altitude wind turbine equipment. Specifically, the staff controls the casing 1 to approach the wind turbine equipment, and controls the adsorption component to contact the surface of the wind turbine equipment through the receiving plate 2, and fixes the casing 1 on the surface of the wind turbine equipment through the adsorption component, and then restricts the camera 11 on the casing 1 to be fixed on one side of the wind turbine equipment. After that, the image collected by the camera 11 remains stable, and the influence of wind force on the camera 11 is greatly weakened, thereby avoiding affecting the staff's judgment on the detection results.

[0036] like Figures 1 to 4 As shown, the adsorption component includes a connecting component, a first motor 23 is arranged on the surface of the connecting component, a receiving wheel 24 is arranged at the end of the output end of the first motor 23, a plurality of air extraction grooves 25 are opened on the wheel surface of the receiving wheel 24, a suction cup 26 is inserted into the interior of the air extraction groove 25, and the opening part of the suction cup 26 is located on the outside of the air extraction groove 25; an air pump 3 is arranged on the side of the receiving wheel 24, a plurality of first conduits 31 are connected to the input end of the air pump 3, and a first solenoid valve 32 is connected to the end of the first conduit 31 away from the air pump 3; the output end of the first solenoid valve 32 When the adsorption component is adsorbed to the surface of the wind turbine generator set, the connection component drives the outermost suction cup 26 to press against the surface of the wind turbine generator set through the receiving wheel 24, and the opening of the suction cup 26 is blocked by the surface of the wind turbine generator set, and the air pump 3 is in the starting state, and the air pump 3 draws air into the air extraction groove 25 through the first conduit 31 and the first solenoid valve 32, so that the suction cup 26 is adsorbed to the surface of the wind turbine generator set; then the first motor 23 is started, and the first motor 23 drives the receiving wheel 24 to rotate, and at the same time the microcomputer controls different A solenoid valve 32 is opened and closed. Specifically, when the receiving wheel 24 rotates, the air pump 3 first inflates the suction cup 26 in contact with the surface of the wind turbine equipment through the first conduit 31 and the first solenoid valve 32, so that the suction cup 26 reduces the adsorption force on the wind turbine equipment; then, as the receiving wheel 24 rotates, the suction cup 26 adsorbed on the surface of the wind turbine equipment is pulled and deformed, and at the same time, the opening of the other suction cup 26 is blocked by the surface of the wind turbine equipment. At this time, the first solenoid valve 32 corresponding to the suction cup 26 originally connected to the wind turbine equipment is closed, and the suction cup 26 currently connected to the wind turbine equipment is closed. The first solenoid valve 32 corresponding to the contacted suction cup 26 opens, and as the receiving wheel 24 continues to rotate, the suction cup 26 that was originally in contact with the wind turbine equipment falls off from the surface of the wind turbine equipment due to the reduction of the adsorption force; the current suction cup 26 is adsorbed to the surface of the wind turbine equipment, completing the alternating adsorption between the suction cups 26; in this process, the receiving wheel 24 is continuously restricted to the surface of the wind turbine equipment, so that the housing 1 drives the camera 11 to move on the surface of the wind turbine equipment and remain stable; facilitating the camera 11 to stably collect the inspection images of the wind turbine equipment.

[0037] The connecting assembly includes a second motor 21 and a connecting frame 22; the shell portion of the second motor 21 is installed on the side of the receiving plate 2, and the output end of the second motor 21 is connected to the connecting frame 22; the shell portion of the first motor 23 is installed on the side of the connecting frame 22; when in use, the second motor 21 can drive the connecting frame 22 to rotate, and the connecting frame 22 drives the receiving wheel 24 to rotate synchronously. Specifically, the first motor 23 is a servo motor that can control the rotation angle; so that the receiving wheel 24 is suitable for partial detection of different angles on the wind turbine equipment; for example, for the detection of the fan blades of the generator, the receiving wheel 24 needs to roll on the fan blade at an angle of the tilting effect; therefore, the setting of the second motor 21 and the connecting frame 22 improves the comprehensiveness of the inspection of the wind turbine equipment.

[0038] like Figures 4 to 7 As shown, the wheel surface of the receiving wheel 24 is provided with a plurality of collars 4, the number of which is the same as the number of the suction cups 26; and the collars 4 are sleeved on the outer side of the suction cups 26; an annular airbag 41 is provided on the side of the collar 4 facing the suction cups 26; a connecting hose 42 is provided on the side of the annular airbag 41, and a second conduit 43 is provided on the end of the connecting hose 42 away from the annular airbag 41; a second solenoid valve 44 is provided on the end of the second conduit 43 away from the connecting hose 42, and the input end of the second solenoid valve 44 is connected to the output end of the air pump 3; when the opening of the suction cup 26 is pressed against When the suction cup 26 touches the surface of the wind turbine equipment, the airflow output through the output end of the air pump 3 enters the second duct 43 through the input end of the second solenoid valve 44, and then enters the annular airbag 41 through the connecting hose 42. Then the annular airbag 41 expands to press against the side of the suction cup 26, so that the opening part of the suction cup 26 is pressed against the surface of the wind turbine equipment, thereby improving the sealing effect between the suction cup 26 and the surface of the wind turbine equipment; it is beneficial to ensure the stability of the use of the suction cup 26; it should be pointed out that the second solenoid valve 44 corresponding to the suction cup 26 is synchronously adaptively opened and closed.

[0039] The output end of the air pump 3 is connected to a pressure relief valve (not shown in the drawings of the specification); when the second solenoid valve 44 is opened, the annular airbag 41 is connected to the output end of the air pump 3; when the air pump 3 injects air into the annular airbag 41 causing the air pressure in the annular airbag 41 to be too high, the pressure relief valve opens to release air to prevent the annular airbag 41 from being damaged due to excessive air pressure.

[0040] An annular groove 5 is provided on the side of the ring 4 facing the suction cup 26. The annular groove 5 surrounds the annular airbag 41 and an annular plate 51 is inserted inside. The end of the annular plate 51 outside the annular groove 5 is connected to the annular airbag 41; when the annular airbag 41 expands, the annular plate 51 is located on the outside of the annular airbag 41 to limit the expansion direction of the annular airbag 41, and the end of the annular plate 51 outside the annular groove 5 is connected to the annular airbag 41. Therefore, as the annular airbag 41 expands, the annular plate 51 is driven to move in the annular groove 5 to continuously limit the expansion of the annular airbag 41. It should be pointed out that during the expansion of the annular airbag 41, the annular plate 51 does not separate from the annular groove 5.

[0041] like Figures 8 to 9As shown, a third motor 61 is installed on the side of the connecting frame 22, and a rotating roller 6 is provided at the output end of the third motor 61, and a pair of protrusions are symmetrically provided on the roller surface of the rotating roller 6; when the receiving wheel 24 rotates, the receiving wheel 24 drives the opening of the suction cup 26 to contact the rotating roller 6; when the receiving wheel 24 rotates, the third motor 61 is started, driving the rotating roller 6 to rotate synchronously, and when the receiving wheel 24 drives the opening of the suction cup 26 to contact the rotating roller 6, the protrusion on the rotating rotating roller 6 squeezes the opening of the suction cup 26, and the opening of the suction cup 26 is squeezed by the protruding part of the rotating roller 6 and as the rotating roller 6 rotates, the opening part of the suction cup 26 is scraped, so that the dust contaminated on the opening part of the suction cup 26 from the surface of the wind turbine equipment is cleaned; it is conducive to the normal use of the subsequent suction cup 26.

[0042] A pair of grooves are provided at the end of the rotating roller 6, and a centrifugal block 62 is inserted into the groove; a pair of connecting springs are provided between the end of the centrifugal block 62 and the inner wall of the groove; when in use, the third motor 61 is controlled to change speed and rotate, so that the centrifugal force exerted on the centrifugal block 62 changes, so that the centrifugal block 62 will reciprocate in the groove based on the pulling force of the connecting spring, and intermittently disengage from the groove; the opening part of the suction cup 26 is impacted, thereby causing the suction cup 26 to vibrate, and when the suction cup 26 vibrates, the dust in the opening part is accelerated to fall off, which is beneficial to the cleaning of the suction cup 26.

[0043] The surfaces of the first motor 23, the second motor 21, and the third motor 61 are all covered with windproof plates (not shown in the drawings of the specification) to prevent dust or rain carried by the air from directly entering the heat dissipation holes of the first motor 23, the second motor 21, and the third motor 61 at high altitudes and causing damage.

[0044] The structure of the adsorption component is made of lightweight plastic, which reduces the weight of the drone and the power consumption of the drone, and helps to increase the inspection time of the drone.

[0045] When working, the staff controls the fan blade assembly of the drone to start, driving the housing 1 and the camera 11 to inspect the high-altitude wind turbine equipment. Specifically, the staff controls the housing 1 to approach the wind turbine equipment, and controls the adsorption assembly to contact the surface of the wind turbine equipment through the receiving plate 2, and fixes the housing 1 on the surface of the wind turbine equipment through the adsorption assembly, thereby restricting and fixing the camera 11 on the housing 1 to one side of the wind turbine equipment. After that, the picture collected by the camera 11 remains stable, and the influence of wind force on the camera 11 is greatly weakened; Avoid affecting the staff's judgment on the test results; when the adsorption component is adsorbed to the surface of the wind turbine equipment, the connection component drives the outermost suction cup 26 to press against the surface of the wind turbine equipment through the receiving wheel 24, and the opening part of the suction cup 26 is blocked by the surface of the wind turbine equipment, and the air pump 3 is in the starting state, and the air pump 3 draws air into the exhaust groove 25 through the first conduit 31 and the first solenoid valve 32, so that the suction cup 26 is adsorbed to the surface of the wind turbine equipment; then the first motor 23 is started, and the first motor 23 drives the receiving wheel 24 to rotate, and at the same time the microcomputer Control the opening and closing of different first solenoid valves 32. Specifically, when the receiving wheel 24 rotates, the air pump 3 first inflates the suction cup 26 in contact with the surface of the wind turbine equipment through the first conduit 31 and the first solenoid valve 32, so that the suction cup 26 reduces the adsorption force on the wind turbine equipment; then, as the receiving wheel 24 rotates, the suction cup 26 adsorbed on the surface of the wind turbine equipment is pulled and deformed, and at the same time, the opening of the other suction cup 26 is blocked by the surface of the wind turbine equipment. At this time, the first solenoid valve 32 corresponding to the suction cup 26 originally connected to the wind turbine equipment is closed, and the suction cup 26 currently connected to the wind turbine equipment is closed. The first solenoid valve 32 corresponding to the suction cup 26 in contact with the equipment opens, and as the receiving wheel 24 continues to rotate, the suction cup 26 that was originally in contact with the wind turbine equipment falls off from the surface of the wind turbine equipment due to the reduction of the adsorption force; the current suction cup 26 is adsorbed to the surface of the wind turbine equipment, completing the alternating adsorption between the suction cups 26; in this process, the receiving wheel 24 is continuously restricted to the surface of the wind turbine equipment, so that the housing 1 drives the camera 11 to move on the surface of the wind turbine equipment and remain stable; facilitating the camera 11 to stably collect the inspection images of the wind turbine equipment.

[0046] When in use, the second motor 21 can drive the connecting frame 22 to rotate, and the connecting frame 22 drives the receiving wheel 24 to rotate synchronously. Specifically, the first motor 23 is a servo motor, which can control the rotation angle; so that the receiving wheel 24 is suitable for partial detection of different angles on the wind turbine equipment; for example, for the detection of the fan blades of the generator, the receiving wheel 24 needs to roll on the fan blade at an angle of tilting effect; therefore, the arrangement of the second motor 21 and the connecting frame 22 improves the comprehensiveness of the inspection of the wind turbine equipment; when the opening of the suction cup 26 is pressed against the surface of the wind turbine equipment, the airflow output through the output end of the air pump 3 enters the second conduit 43 through the input end of the second solenoid valve 44, and then enters the annular airbag 41 through the connecting hose 42, and then the annular airbag The expansion of the bag 41 produces a pressure on the side of the suction cup 26, so that the opening part of the suction cup 26 is pressed against the surface of the wind turbine equipment, thereby improving the sealing effect between the suction cup 26 and the surface of the wind turbine equipment; it is beneficial to ensure the stability of the use of the suction cup 26; wherein when the second solenoid valve 44 is opened, the annular airbag 41 is connected to the output end of the air pump 3; when the air pump 3 injects air into the annular airbag 41 and the air pressure in the annular airbag 41 is too high, the pressure relief valve opens to release air to avoid damage caused by excessive air pressure in the annular airbag 41; wherein when the annular airbag 41 expands, the annular plate 51 is located on the outside of the annular airbag 41 to limit the expansion direction of the annular airbag 41, and the end of the annular plate 51 located outside the annular groove 5 is connected to the annular airbag 41 Therefore, as the annular airbag 41 expands, the annular plate 51 is driven to move in the annular groove 5, continuously limiting the expansion of the annular airbag 41; when the receiving wheel 24 rotates, the third motor 61 is started to drive the rotating roller 6 to rotate synchronously, and when the receiving wheel 24 drives the opening of the suction cup 26 to contact the rotating roller 6, the protrusion on the rotating rotating roller 6 squeezes the opening of the suction cup 26, and the opening of the suction cup 26 is squeezed by the protruding part of the rotating roller 6 and as the rotating roller 6 rotates, the opening part of the suction cup 26 is scraped, so that the dust on the surface of the wind turbine equipment at the opening part of the suction cup 26 is cleaned; it is conducive to the normal use of the subsequent suction cup 26; when in use, the third motor 61 is controlled to rotate at a variable speed so that the centrifugal block 62 is subjected to the centrifugal The force changes, so the centrifugal block 62 will move back and forth in the groove based on the tension of the connecting spring, and intermittently disengage from the groove; it impacts the opening part of the suction cup 26, which causes the suction cup 26 to vibrate. When the suction cup 26 vibrates, the dust in the opening part is accelerated to fall off, which is beneficial to the cleaning of the suction cup 26; the surfaces of the first motor 23, the second motor 21, and the third motor 61 are all sleeved with windproof plates (not shown in the drawings of the specification); dust or rain carried by the air at high altitudes is prevented from directly pouring into the heat dissipation holes of the first motor 23, the second motor 21, and the third motor 61, causing damage; the structure of the adsorption component is made of lightweight plastic; the weight of the drone is reduced, and the power consumption of the drone is reduced; it is beneficial to increase the inspection time of the drone.
