Description

Technical Field

[0001] The utility model relates to the technical field of UAV inspection, and particularly relates to a UAV inspection device for a photovoltaic power station. Background Technique

[0002] UAV inspection of photovoltaic power stations is an innovative method that combines UAV technology with the maintenance of photovoltaic power stations. By using UAVs to conduct efficient inspection, monitoring, and maintenance of photovoltaic power stations, this inspection method is based on AI image recognition technology. Industry-level UAVs are used to automatically fly following the terrain to collect visible light and infrared temperature images, accurately and efficiently detecting defect faults of solar photovoltaic panels.

[0003] The existing Chinese patent: a UAV inspection device for a photovoltaic power station, patent number: CN216301505U, includes a UAV body. An installation box is bolted to the bottom of the UAV body. A clamping mechanism is arranged in the inner cavity of the installation box. Both sides of the bottom of the installation box are movably connected with connecting plates. A protective frame is bolted to the opposite sides of the connecting plates. Through the cooperation of a first motor, a driving gear, a driven gear, a positive and negative threaded rod, a first threaded sleeve, a fixed block, and a clamping rod, it is convenient for users to install and disassemble the protective frame, so as to cover the camera in the protective frame to protect the camera, prevent the camera from being easily collided with sundries during use, resulting in the camera lens being blurred and the camera being damaged. Through the cooperation of a second motor, a lead screw, a second threaded sleeve, a brush, a sliding column, and a sliding sleeve, the front of the protective frame is cleaned to remove the dust on the front of the protective frame, preventing the dust from affecting the shooting effect of the camera.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: in the above UAV inspection device, the dust on the surface of the protective frame is directly cleaned by a brush. The fine particles such as silicon dioxide contained in the dust have a high hardness, and directly brushing is likely to scratch the protective frame, resulting in blurred shooting. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the utility model provides a UAV inspection device for a photovoltaic power station, which solves the technical problem that in the above UAV inspection device, the dust on the surface of the protective frame is directly cleaned by a brush. The fine particles such as silicon dioxide contained in the dust have a high hardness, and directly brushing is likely to scratch the protective frame, resulting in blurred shooting.

[0007] (2) Technical Solutions

[0008] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0009] A photovoltaic power station drone inspection device includes a drone body and a landing gear. A glass protective cover is fixedly installed at the side end of the landing gear, and a spray pipe is fixedly installed at the side end of the landing gear. A water tank is fixedly installed inside the landing gear, a water pump is fixedly installed at the bottom end of the water tank, and a water delivery pipe is fixedly installed at the bottom end of the water pump; the end of the water delivery pipe is connected to the spray pipe. A threaded rod is rotatably installed at the bottom end of the landing gear, a brush plate is threadedly installed on the threaded rod, and a motor is fixedly installed at the bottom end of the landing gear; the motor drives the threaded rod to rotate through the engagement of gears. A pan-tilt is fixedly installed inside the glass protective cover, a camera is installed inside the pan-tilt, and a grid plate is fixedly installed inside the water tank.

[0010] Preferably, a water filling pipe is fixedly installed at the side end of the water tank.

[0011] Preferably, two bolts are symmetrically threadedly installed on both sides of the landing gear.

[0012] (III) Beneficial effects

[0013] First, before use, it is necessary to first add a cleaning agent and clean water into the water tank through the water filling pipe, and then operate the drone body to take off and inspect the photovoltaic power station through the camera. When dust adheres to the glass protective cover during the shooting process, the water pump is started, and the water inside the water tank is conveyed to the spray pipe through the water delivery pipe, and then sprayed on the glass protective cover through the opening at the side end of the spray pipe to moisten the dust on the glass protective cover. The motor is started to drive the threaded rod to rotate through the engagement of gears. Since the threaded rod is threadedly connected to the brush plate, the rotation of the threaded rod will push the brush plate to slide, and the sliding brush plate can brush the moistened dust on the surface of the glass protective cover. The friction between the moistened dust and the glass protective cover is greatly reduced. By first moistening the dust on the surface of the glass protective cover through the spray pipe and then brushing, it can avoid scratching the glass protective cover and achieve the effect of improving the shooting clarity.

[0014] Second, the water tank is located in the exact center of the landing gear, ensuring that the center of gravity of the water tank is always located at the center position of the drone body, avoiding the center of gravity shift caused by the reduction of the water source inside the water tank. The grid plate inside the water tank can divide the water in the water tank to prevent the water from sloshing back and forth when the drone is flying at a high speed, which affects the flight stability. When it is necessary to maintain the drone body or the landing gear, loosen the two bolts, and then the drone body or the landing gear can be slid from the side to separate the drone body and the landing gear for maintenance.

[0022] In the embodiment of the present application, by providing a UAV inspection device for a photovoltaic power station, the above technical problem that in the UAV inspection device, the dust on the surface of the protection frame is directly cleaned by a brush, and the fine particles such as silicon dioxide contained in the dust have a high hardness, and the protection frame is easily scratched by direct brushing, resulting in blurred shooting, is effectively solved. Before use, it is necessary to first add a cleaning agent and clean water into the water tank through the water filling pipe, and then operate the UAV body to take off and inspect the photovoltaic power station through the camera shooting. When dust adheres to the glass protective cover during the shooting process, the water pump is started, and the water in the water tank is transported to the spraying pipe through the water delivery pipe, and then sprayed on the glass protective cover through the opening at the side end of the spraying pipe to moisten the dust on the glass protective cover. The motor is started to drive the threaded rod to rotate through the meshing of the gears. Since the threaded rod is threadedly connected to the brush plate, the rotation of the threaded rod will push the brush plate to slide, and the sliding brush plate can brush the moistened dust on the surface of the glass protective cover. The friction between the moistened dust and the glass protective cover is greatly reduced. By first moistening the dust on the surface of the glass protective cover through the spraying pipe and then brushing, the glass protective cover can be prevented from being scratched, and the effect of improving the shooting clarity is achieved. The water tank is located in the center of the landing gear, ensuring that the center of gravity of the water tank is always located at the center of the UAV body, avoiding the center of gravity shift caused by the reduction of the water source in the water tank. The grid plate in the water tank can divide the water in the water tank to prevent the water from sloshing back and forth due to the too fast flight speed of the UAV, affecting the flight stability. When maintenance needs to be carried out on the UAV body or the landing gear, loosen the two bolts, and the UAV body or the landing gear can be slid from the side to separate the UAV body and the landing gear for maintenance.

[0023] Embodiment

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the technical solution in the embodiment of the present application effectively solves the above-mentioned technical problem of the drone inspection device. By directly cleaning the dust on the surface of the protective frame with a brush, the fine particles such as silicon dioxide contained in the dust have a relatively high hardness, and directly brushing is likely to scratch the protective frame, resulting in blurred shooting. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the present utility model provides a drone inspection device for a photovoltaic power station, including a drone main body 1 and a landing gear 2. A glass protective cover 3 is fixedly installed at the side end of the landing gear 2, a spray pipe 4 is fixedly installed at the side end of the landing gear 2, a water tank 9 is fixedly installed inside the landing gear 2, a water pump 11 is fixedly installed at the bottom end of the water tank 9, and a water delivery pipe 8 is fixedly installed at the bottom end of the water pump 11.

[0026] The end of the water delivery pipe 8 is connected to the spray pipe 4. A threaded rod 5 is rotatably installed at the bottom end of the landing gear 2, a brush plate 6 is threadedly installed on the threaded rod 5, and a motor 7 is fixedly installed at the bottom end of the landing gear 2; the motor 7 drives the threaded rod 5 to rotate through the engagement of gears.

[0027] A pan-tilt 15 is fixedly installed inside the glass protective cover 3, a camera 16 is installed inside the pan-tilt 15, a grid plate 12 is fixedly installed inside the water tank 9, a water filling pipe 13 is fixedly installed at the side end of the water tank 9, and two bolts 14 are symmetrically threadedly installed on both sides of the landing gear 2.

[0028] Working principle:

[0029] First step, the motor 7, the water delivery pipe 8, and the cloud platform 15 are connected to the control system of the UAV main body 1 through wires, and the camera 16 is connected to the image transmission system of the UAV main body 1 through wires. Before use, it is necessary to first add cleaning agent and clean water into the water tank 9 through the water filling pipe 13, and then operate the UAV main body 1 to take off and conduct an inspection of the photovoltaic power station through the camera 16. When dust adheres to the glass protective cover 3 during the shooting process, the water pump 11 is started, and the water in the water tank 9 is conveyed to the spray pipe 4 through the water delivery pipe 8, and then sprayed on the glass protective cover 3 through the opening on the side end of the spray pipe 4 to moisten the dust on the glass protective cover 3. The motor 7 is started to drive the threaded rod 5 to rotate through the meshing of gears. Since the threaded rod 5 is threadedly connected to the brush plate 6, the rotation of the threaded rod 5 will push the brush plate 6 to slide, and the sliding brush plate 6 can brush the moistened dust on the surface of the glass protective cover 3. The friction between the moistened dust and the glass protective cover 3 is greatly reduced. By first moistening the dust on the surface of the glass protective cover 3 through the spray pipe 4 and then brushing it, the glass protective cover 3 can be prevented from being scratched, achieving the effect of improving the shooting clarity.

[0030] Second step, the water tank 9 is located in the center of the landing gear 2, ensuring that the center of gravity of the water tank 9 is always located at the center position of the UAV main body 1, avoiding the center of gravity shift caused by the reduction of the water source inside the water tank 9. The grid plate 12 inside the water tank 9 can divide the water in the water tank 9 to prevent the water from sloshing back and forth and affecting the flight stability when the UAV is flying at a high speed. When maintenance needs to be carried out on the UAV main body 1 or the landing gear 2, loosen the two bolts 14, and the UAV main body 1 or the landing gear 2 can be slid from the side to separate the UAV main body 1 and the landing gear 2 for maintenance.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
