Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic panel cleanliness detection technology, and in particular relates to a drone for photovoltaic panel cleanliness detection. Background Technology
[0002] The drone for inspecting the cleanliness of photovoltaic panels is a solution that uses drone technology to efficiently and accurately inspect the cleanliness of photovoltaic panels.
[0003] Existing drones for inspecting the cleanliness of photovoltaic panels require disassembly and maintenance after prolonged use. The equipment is then reinstalled on the drone. However, the installation of these devices is often difficult and requires two workers: one to support and lift the device while the other performs the installation. Furthermore, the installation process involves constant adjustments to align the holes, resulting in low efficiency and making it inconvenient for a single person to perform the installation. Therefore, we propose a drone for inspecting the cleanliness of photovoltaic panels. Utility Model Content
[0004] The purpose of this invention is to provide a drone for detecting the cleanliness of photovoltaic panels. By setting up a mounting plate, specifically, the mounting plate on top of the cleanliness detection device is aligned with a mounting disk. A square positioning block is inserted into the mounting plate for positioning, ensuring that the mounting protrusion aligns smoothly with the threaded shaft, facilitating subsequent installation and fixing. Simultaneously, the mounting disk pushes the locking block. When the bottom of the mounting disk contacts the top of the mounting plate, the locking block springs back to its original position under the elastic action of a spring, thus supporting the cleanliness detection device. This eliminates the need for workers to support the cleanliness detection device, reducing labor costs and enabling rapid installation. It solves the problem that installing cleanliness detection devices previously required two workers, resulting in low installation efficiency and inconvenience for a single person.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a drone for detecting the cleanliness of photovoltaic panels, comprising a drone body, a support, a cleanliness detection device disposed below the support, a fixed plate fixedly connected to the bottom of the support, a lifting assembly disposed above the cleanliness detection device, the lifting assembly comprising a fixed column, a mounting plate disposed below the fixed column, a mounting plate fixedly connected to the top of the cleanliness detection device, a square groove formed at the center of the mounting plate, a square positioning block fixedly connected to the center of the bottom of the mounting plate, the square positioning block being inserted into the mounting plate through the square groove, four locking blocks disposed on the top of the mounting plate, the four locking blocks being arranged in a circumferential array around the mounting plate, a support block being rotatably connected to the bottom of each locking block via a pin, the bottom of the support block being fixedly connected to the top of the mounting plate, and a spring piece fixedly connected to the side of each locking block away from the mounting plate, the bottom of the spring piece being fixedly connected to the top of the mounting plate.
[0007] Furthermore, threaded shafts are fixedly connected to the four corners of the top of the mounting plate, and nuts are threaded onto the outer surface of the threaded shafts. The top of the mounting plate contacts the bottom of the mounting disk. Four mounting protrusions are fixedly connected to the outer surface of the mounting disk. The four mounting protrusions are arranged in a circumferential array with the mounting disk as the center. The mounting protrusions are inserted into the threaded shafts. The top of the locking block is set with an incline. The side of the locking block near the mounting disk is recessed. The recess on the locking block contacts the surface of the mounting disk.
[0008] Furthermore, the top of the fixing column is fixedly connected to the bottom of the fixing plate, a motor is fixedly connected to the right side of the fixing column, an internally threaded swivel is provided inside the fixing column, and a threaded rod is threadedly connected inside the internally threaded swivel.
[0009] Furthermore, the bottom of the threaded rod is fixedly connected to the top of the mounting plate, a bevel gear is provided on the right side of the fixing column, the right side of the bevel gear is fixedly connected to the left output end of the motor, a square groove is opened inside the threaded rod, a square column is slidably connected to the inner wall of the square groove, and the top of the square column is fixedly connected to the bottom of the fixing plate.
[0010] Furthermore, a bevel gear ring is fixedly connected to the outer surface of the internal threaded swivel, and the bevel gear ring meshes with a bevel gear. Limiting rings are rotatably connected to both the outer and inner sides of the top of the internal threaded swivel, and the tops of the two limiting rings are fixedly connected to the bottom of the fixed disk.
[0011] This utility model has the following beneficial effects:
[0012] This invention features a mounting plate, specifically an mounting plate on top of the cleanliness testing equipment that aligns with a mounting disc. A square positioning block is inserted into the mounting plate for positioning, ensuring the mounting protrusion aligns smoothly with the threaded shaft for easy subsequent installation and fixation. Simultaneously, the mounting disc pushes the locking block. When the bottom of the mounting disc contacts the top of the mounting plate, the locking block springs back to its original position under the elastic action of a spring, thus supporting the cleanliness testing equipment. This eliminates the need for workers to support the cleanliness testing equipment, reducing labor and enabling rapid installation.
[0013] This invention features a lifting assembly. Specifically, a starting motor drives a bevel gear to rotate counterclockwise. This bevel gear then drives a bevel gear ring to rotate clockwise, which in turn drives an internal threaded ring to rotate. The threaded rod then moves the cleanliness testing device downwards, placing it below the landing gear for better inspection of the photovoltaic panels. This reduces obstruction and allows the cleanliness testing device to have a wider observation range and higher testing efficiency.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figure 1-6As shown, this utility model is a drone for detecting the cleanliness of photovoltaic panels, including a drone body 1. The drone body 1 includes a support 11. A cleanliness detection device 12 is arranged below the support 11. A fixed plate 111 is fixedly connected to the bottom of the support 11. A lifting assembly 13 is arranged above the cleanliness detection device 12. The lifting assembly 13 includes a fixed column 131. A mounting plate 133 is arranged below the fixed column 131. A mounting plate 121 is fixedly connected to the top of the cleanliness detection device 12. A square groove is opened in the center of the mounting plate 121. A square positioning block 332 is fixedly connected to the center of the bottom of the mounting plate 133. The square positioning block 332 passes through... The square slot is inserted into the mounting plate 121. The top of the mounting plate 121 has four locking blocks 124 arranged in a circular array around the mounting plate 133. The bottom of each locking block 124 is rotatably connected to a support block 241 via a pin. The bottom of the support block 241 is fixedly connected to the top of the mounting plate 121. A spring piece 242 is fixedly connected to the side of the locking block 124 away from the mounting plate 133, and the bottom of the spring piece 242 is fixedly connected to the top of the mounting plate 121. When the mounting plate 121 on top of the cleanliness testing device 12 is aligned with the mounting plate 133, the square positioning block 332 is inserted into the mounting plate 121 to provide positioning, thus positioning the mounting protrusion 33. 1. It can be smoothly aligned with the threaded shaft 122, facilitating subsequent installation and fixing. Simultaneously, the mounting plate 133 pushes the locking block 124. When the bottom of the mounting plate 133 contacts the top of the mounting plate 121, the locking block 124 springs back to its original position under the elastic action of the spring piece 242, thus supporting the cleanliness testing device 12. At this point, the worker does not need to support the cleanliness testing device 12, reducing labor and enabling rapid completion of the installation work. Threaded shafts 122 are fixedly connected to the four corners of the top of the mounting plate 121. Nuts 123 are threaded onto the outer surface of the threaded shafts 122. The top of the mounting plate 121 contacts the bottom of the mounting plate 133. Four mounting protrusions 331 are fixedly connected to the outer surface of the mounting plate 133. The four mounting protrusions 331 are arranged in a circumferential array with the mounting plate 133 as the center. The mounting protrusions 331 are inserted into the threaded shaft 122. The top of the locking block 124 is set with a slope, and the side of the locking block 124 near the mounting plate 133 is set with a recess. The recess on the locking block 124 contacts the surface of the mounting plate 133. Since the top of the locking block 124 is set with a slope, when the mounting plate 133 contacts the locking block 124, it will push the locking block 124. The bottom of the locking block 124 rotates on the support block 241 through the pin and squeezes the spring piece 242, so that the mounting plate 133 can pass through the locking block 124.The top of the fixed column 131 is fixedly connected to the bottom of the fixed plate 111. A motor 132 is fixedly connected to the right side of the fixed column 131. An internally threaded rotating ring 311 is provided inside the fixed column 131, and a threaded rod 134 is threadedly connected inside the internally threaded rotating ring 311. When the motor 132 is started, it drives the bevel gear 135 to rotate counterclockwise. At this time, the bevel gear 135 drives the bevel gear ring 312 to rotate clockwise, and the bevel gear ring 312 drives the internally threaded rotating ring 311 to rotate. At this time, the threaded rod 134 will drive the cleanliness detection device 12 to move downward, so that it moves below the landing gear 112, so as to better detect the photovoltaic panel, reduce the shading, and make the observation range of the cleanliness detection device 12 wider and the detection efficiency higher. The bottom of the threaded rod 134 is fixedly connected to the top of the mounting plate 133. A bevel gear 135 is provided on the right side of the fixed column 131. The right side of motor 135 is fixedly connected to the left output end of motor 132. A square groove 341 is opened inside the threaded rod 134, and a square post 342 is slidably connected to the inner wall of the square groove 341. The top of the square post 342 is fixedly connected to the bottom of the fixed disk 111. The threaded rod 134 is slidably connected to the square post 342 through the square groove 341, which serves to limit the movement of the threaded rod 134, allowing it to move linearly. A bevel gear ring 312 is fixedly connected to the outer surface of the internal threaded rotating ring 311, meshing with the bevel gear 135. Limiting rings 313 are rotatably connected to both the outer and inner sides of the top of the internal threaded rotating ring 311. The tops of both limiting rings 313 are fixedly connected to the bottom of the fixed disk 111. The limiting rings 313 support and limit the movement of the internal threaded rotating ring 311, allowing it to rotate in its original position.
[0026] One specific application of this embodiment is:
[0027] When the cleanliness testing device 12 needs to be installed, the mounting plate 121 on top of the cleanliness testing device 12 is aligned with the mounting disc 133. At this time, the square positioning block 332 at the bottom of the mounting disc 133 will be inserted into the mounting plate 121, thereby playing a positioning role, so that the mounting protrusion 331 can be smoothly aligned with the threaded shaft 122. At the same time, when the mounting disc 133 contacts the locking block 124, it will push the locking block 124. The bottom of the locking block 124 rotates on the support block 241 through the pin, and squeezes the spring piece 242, so that the mounting disc 133 can pass through the locking block 124. After the bottom of the mounting plate 133 contacts the top of the mounting plate 121, the locking block 124 springs back to its original position under the elastic action of the spring piece 242, thereby locking and fixing the mounting plate 133. The cleanliness testing device 12 is then supported, and the mounting protrusion 331 is inserted into the threaded shaft 122. At this point, the operator does not need to support the cleanliness testing device 12. The cleanliness testing device 12 is then fixed by threading the nut 123 onto the threaded shaft 122. When the drone body 1 carries the cleanliness testing device 12 to inspect the photovoltaic panels in the air, the starter motor 132 drives the bevel gear. When wheel 135 rotates counterclockwise, bevel gear 135 drives bevel gear ring 312 to rotate clockwise. Bevel gear ring 312 then drives internal threaded rotating ring 311 to rotate within limiting ring 313. Since internal threaded rotating ring 311 is threadedly connected to threaded rod 134, and threaded rod 134 is slidably connected to square post 342 through square groove 341, threaded rod 134 will move downward. At this time, mounting plate 133 will drive cleanliness detection device 12 downward, moving the cleanliness detection device 12 below landing gear 112 for better detection of photovoltaic panels and reducing shading. In the event of obstruction, the cleanliness detection device 12 includes a high-definition camera or an infrared thermal imager, which is used to capture image information of the photovoltaic panel to provide a data basis for subsequent image recognition and analysis. The collected image data is transmitted back to the ground station or host computer through wireless communication technology to determine the cleanliness status of the photovoltaic panel, such as whether there are stains, damage, or other problems. When it is necessary to land the main body of the drone 1, the cleanliness detection device 12 is first retracted upwards and moved above the landing gear 112, and then the main body of the drone 1 is landed to avoid damage to the cleanliness detection device 12.
