Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, and in particular to an inspection UAV for detecting the temperature status of photovoltaic panels. Background Technology

[0002] With the rapid development of photovoltaic power generation technology, the construction of large-scale photovoltaic power plants is increasing. The operating status of photovoltaic modules directly affects power generation efficiency, and abnormal temperatures (such as hot spot effect, localized overheating, etc.) are one of the main reasons for the degradation or even damage of module performance. Therefore, it is crucial to regularly monitor the temperature of photovoltaic panels.

[0003] Currently, infrared thermal imagers have become the core equipment for photovoltaic (PV) inspections, enabling non-contact measurement of surface temperature distribution on PV panels and rapid identification of abnormal heat-generating areas. However, PV power plants are typically built in open areas (such as deserts, Gobi, and wastelands), where pollutants such as dust, sand, and rainwater easily adhere to the PV panels and inspection equipment. When drones equipped with infrared thermal imagers conduct inspections, if the lens is obstructed by dust, it can lead to blurred images, increased temperature measurement errors, and even the inability to accurately identify hot spot faults.

[0004] Therefore, this application proposes an inspection drone for detecting the temperature status of photovoltaic panels to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8 This utility model provides a technical solution: an inspection drone for detecting the temperature status of photovoltaic panels, comprising a drone body 1, an equipment mounting plate 4 disposed below the drone body 1, a gimbal 8 fixedly connected to the lower end of the equipment mounting plate 4, an infrared thermal imager 9 disposed at the lower end of the gimbal 8, a protective cover 5 rotatably connected to the lower end of the equipment mounting plate 4, an adjustment motor 11 fixedly connected to the upper end of the equipment mounting plate 4, the output end of the adjustment motor 11 passing through the equipment mounting plate 4 and fixedly connected to an adjustment gear 12, an adjustment gear ring 10 fixedly connected to the inner side wall of the protective cover 5, the inner end of the adjustment gear ring 10 being provided with meshing teeth, and the adjustment gear 12 engaging with the adjustment gear 12 through the meshing teeth. The gear ring 10 is engaged, and a cleaning scraper 13 is fixedly connected to the lower end of the equipment mounting plate 4. The protective cover 5 is located inside the cleaning scraper 13. The cleaning scraper 13 is U-shaped, and a cleaning wiping cotton 14 is fixedly connected to the inner wall of the cleaning scraper 13. After long-term flight testing, dust easily adheres to the surface of the protective cover 5. At this time, the adjusting motor 11 drives the adjusting gear 12 to rotate. Through the engagement of the adjusting gear 12 and the adjusting gear ring 10, the protective cover 5 is rotated. During the rotation of the protective cover 5, the cleaning scraper 13 and the cleaning wiping cotton 14 are engaged to clean the outer wall of the protective cover 5, thereby ensuring that external dust will not affect the testing equipment.

[0028] The protective cover 5 is made of a high light transmittance material, and the inner wall of the cleaning and wiping cotton 14 has a wave-shaped structure design. The wave-shaped structure can better fit the small unevenness on the outer wall of the protective cover 5 and achieve multiple wiping and cleaning.

[0029] An auxiliary electric push rod 6 is fixedly connected to the upper end of the equipment mounting plate 4. A contact plate 7 is fixedly connected to the output end of the auxiliary electric push rod 6. The contact plate 7 is located directly below the main body of the UAV 1. During the detection process, the auxiliary electric push rod 6 is used to push the contact plate 7 to contact the lower end of the main body of the UAV 1 to ensure the stability of the equipment mounting plate 4. At the same time, it works with the gimbal 8 to ensure the stability of the infrared thermal imager 9.

[0030] Two connecting frames 15 are provided above the equipment mounting plate 4. Support rods 2 are fixedly connected to both the left and right ends of the drone body 1. The support rods 2 are L-shaped. The lower end of the support rods 2 is fixedly connected to a support plate 3. The two support rods 2 are located in the two connecting frames 15 respectively. The connecting frames 15 are U-shaped. Connecting bolts 17 are provided above the connecting frames 15. The lower end of the connecting bolts 17 passes through the upper side wall of the connecting frame 15 and the horizontal rod of the support rod 2 and is threaded to a connecting plate 16. The rear end of the connecting plate 16 is slidably connected to the rear inner wall of the connecting frame 15 through a limiting groove. The equipment mounting plate 4 in the device is connected to the drone body 1 through the connecting frames 15 on the left and right sides and the fixing bolts, so that the infrared thermal imager 9 can be installed and disassembled as needed without affecting other uses of the drone.

[0031] Two limiting slide rods 19 are fixedly connected to the upper end of the equipment mounting plate 4. The upper end of the limiting slide rod 19 passes through the lower side wall of the connecting frame 15 and is fixedly connected to the top plate 18. Two buffer springs 20 are sleeved on the limiting slide rod 19. The adjacent ends of the two buffer springs 20 are fixedly connected to the lower inner wall and the lower outer wall of the connecting frame 15, respectively. The ends of the two buffer springs 20 that are far apart from each other are fixedly connected to the lower end of the top plate 18 and the upper end of the equipment mounting plate 4, respectively. The cooperation of the buffer springs 20 and the buffer springs 24 can prevent the impact force when the equipment lands from damaging the equipment.

[0032] Two baffles 21 are installed above the support plate 3. The two baffles 21 are located on the front and rear sides of the support rod 2, respectively. The lower end of the baffle 21 is fixedly connected to the support rod 22. The lower end of the support rod 22 passes through the support plate 3 and is fixedly connected to the contact block 23. The four support rods 22 are all independent, which enables the device to land on uneven ground. The support rod 22 is fitted with a second buffer spring 24. The upper and lower ends of the second buffer spring 24 are fixedly connected to the baffle 21 and the adjacent side wall of the support plate 3, respectively. When landing, the second buffer spring 24 enables the UAV to be better cushioned when landing.

[0033] Working principle: During use, the mounting plate 4 is connected to the support rods 2 on both sides of the drone body 1 using fixing bolts and connecting frame 15. When it is necessary to monitor the temperature of the photovoltaic panel, the drone body 1 lifts the infrared thermal imager 9 to a high altitude. At this time, the auxiliary electric push rod 6 pushes the contact plate 7 to contact the lower end of the drone body 1, thus ensuring the stability of the mounting plate 4. At the same time, it works with the gimbal 8 to ensure the stability of the infrared thermal imager 9. During the detection process, the protective cover 5 protects the infrared thermal imager 9 from infrared thermal imaging. Instrument 9 is susceptible to interference from external dust. The protective cover 5 uses a high-transmittance material to effectively reduce infrared attenuation and ensure normal operation of the testing equipment. After prolonged flight testing, dust easily accumulates on the surface of the protective cover 5. At this time, the adjusting motor 11 drives the adjusting gear 12 to rotate. Through the cooperation of the adjusting gear 12 and the adjusting ring 10, the protective cover 5 rotates. During the rotation of the protective cover 5, the cleaning scraper 13 and cleaning wiping cotton 14 work together to clean the outer wall of the protective cover 5, thus ensuring that external dust does not affect the testing equipment. When the device is about to land, the auxiliary electric push rod 6 retracts, and the contact plate 7 moves away from the lower end of the drone body 1. Upon landing, the second buffer spring 24 provides better cushioning during landing. Simultaneously, a limit slide rod 19 is installed on the equipment mounting plate 4, and a buffer spring 20 is installed between the limit slide rod 19 and the connecting frame 15. The cooperation of the first buffer spring 20 and the second buffer spring 24 prevents damage to the equipment from the impact force during landing.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
