Description

Technical Field

[0001] This invention belongs to the field of infrared drone detection technology, and particularly relates to an infrared drone for detecting hot spots in photovoltaic modules. Background Technology

[0002] The photovoltaic module hot spot detection infrared drone is a specialized drone equipment that integrates infrared thermal imaging technology. Its core purpose is to inspect photovoltaic power plant modules for faults. It can quickly identify hot spot effects caused by problems such as shading, aging, and damage to photovoltaic panels, locate fault points in a timely manner, and ensure the safe and stable operation of the power plant.

[0003] Traditional infrared drones for hot spot detection have poor cushioning performance. Photovoltaic power plants are often deployed in complex terrains such as deserts, mountains, and rooftops. When the drone lands, it is prone to tilting or rigid ground contact. When faced with high landing speed or irregular ground impact, the cushioning tripod may not be able to fully absorb the impact energy, resulting in the impact force being directly transmitted to the fuselage, causing problems such as gimbal shift, infrared camera failure, or even damage to the entire structure. In view of this, we propose an infrared drone for hot spot detection of photovoltaic modules. Summary of the Invention

[0004] The purpose of this invention is to provide an infrared drone for detecting hot spots in photovoltaic modules, in order to solve the problems mentioned in the background art.

A rotating assembly, located within a support frame, is used to drive several screws to rotate.

[0008] In this technical solution, it is ensured that the user can control the elastic force of several buffer springs.

[0009] In the above technical solution, the rotating component further includes: A plurality of first gear slots are formed in the bracket. A first bevel gear and a second bevel gear are rotatably connected in each of the plurality of first gear slots, and the first bevel gear and the second bevel gear mesh with each other.

A plurality of second gear slots are formed in the bracket, and a third bevel gear and a fourth bevel gear are rotatably connected in each of the plurality of second gear slots, and the third bevel gear and the fourth bevel gear mesh with each other; A plurality of through slots are formed in the bracket and are respectively connected to a plurality of first gear slots and a plurality of second gear slots. Each of the plurality of through slots is rotatably connected to a connecting rod, and the two ends of the plurality of connecting rods extend into the plurality of first gear slots and the plurality of second gear slots and are respectively fixedly connected to a plurality of second bevel gears and a plurality of third bevel gears. A plurality of first rotating slots are respectively opened on the bottom surface of the inner wall of a plurality of second gear slots. A first gear is rotatably connected in each of the plurality of first rotating slots, and the top of each of the plurality of first gears extends into the plurality of second gear slots and is fixedly connected to a plurality of fourth bevel gears. The second rotating groove is formed inside the bracket and is connected to several first rotating grooves. A second gear is rotatably connected inside the second rotating groove and meshes with several first gears. A rotating rod is fixedly connected to the bottom surface of the second gear, and one end of the rotating rod passes through the inner wall of the second rotating groove and extends to the outside.

[0010] In this technical solution, it is ensured that the user can drive several screws to rotate simultaneously.

[0011] Furthermore, the above technical solution also includes: The first extrusion block is fixedly connected to the bottom surface of the bracket and is located on one side of the rotating rod; A fixing block is fixedly connected to the bottom surface of the bracket and is located on the other side of the rotating rod. A limiting groove communicating with the outside is opened in the fixing block. A sliding rod is slidably connected in the limiting groove. A second pressing block is fixedly connected to one end of the sliding rod. An adjustment component is located within a fixed block and is used to move a sliding rod.

[0012] In this technical solution, the rotating rod is ensured not to rotate due to external influences, thereby further improving the stability of the overall device.

[0013] In the above technical solution, the adjustment component further includes: Bolts, the bolts being threaded into the slide bar; The third rotating groove is formed on the inner wall of the limiting groove and is connected to the outside.

[0016] In this technical solution, it is ensured that when the bolt rotates, the bolt can rotate normally within the limiting groove, and it is also ensured that when the rotating block rotates, one end of the rotating block can rotate normally within the limiting groove. At the same time, because the rotating block is provided with anti-slip texture on its periphery, when the user rotates the rotating block by hand, the anti-slip texture on the periphery of the rotating block will reduce the possibility of hand slippage.

[0018] In this technical solution, because the threads on several screws have the same direction of rotation and the same thread pitch, when several screws rotate, several pressure plates will be acted upon by the threads of several screws respectively, and move up and down at the same time, ensuring that when several first bevel gears rotate, the bottom ends of several first bevel gears can rotate normally within the bracket, and at the same time, ensuring that when the rotating rod rotates, the rotating rod can rotate normally within the bracket.

[0019] In the above technical solution, further, the two ends of the connecting rod are rotatably connected to the first gear groove and the second gear groove respectively, and the top end of the first gear is rotatably connected to the second gear groove.

[0021] The beneficial effects of this invention are: 1. This photovoltaic module hot spot detection infrared drone, through the setting of brackets, fixing rods, sliding grooves, sliders, buffer feet, and buffer springs, allows several sliders, buffer feet, and buffer springs to buffer the drone.

The above structure design allows the buffer feet to fully absorb the impact energy when the drone faces a large landing speed or irregular ground impact, thereby preventing the impact force from being directly transmitted to the fuselage, causing problems such as gimbal offset, infrared camera failure, or even damage to the entire structure, thus improving the overall buffering performance of the device.

[0022] 2.

[0026] Example 1: This example provides an infrared drone for detecting hot spots on photovoltaic modules, including drone 1, and also including: The bracket 2 is fixedly connected to the bottom surface of the drone 1. Several fixed rods 3 are fixedly connected to the bottom surface of the bracket 2. Each of the fixed rods 3 has a groove 4 that communicates with the outside. Each of the grooves 4 has a slider 5 that is slidably connected. Each of the sliders 5 has a buffer foot 6 fixedly connected to its periphery. Several buffer springs 8 are respectively set in several sliding grooves 4, and the bottom ends of several buffer springs 8 abut against the top surfaces of several sliders 5.

[0027] When the drone 1 faces a large landing speed or irregular ground impact, several buffer feet 6 will contact the ground first. When the buffer feet 6 contact the ground, the impact generated by landing will be initially reduced. At the same time, the buffer feet 6 will squeeze the buffer springs 8 through several sliders 5, thereby further reducing the impact generated by landing and ensuring that the overall device can be provided with buffering capacity.

[0028] Example 2: This example provides an infrared drone for detecting hot spots on photovoltaic modules. In addition to the technical solutions of the above examples, it also has the following technical features and includes: Several pressure plates 7 are slidably connected in several sliding grooves 4. The bottom surfaces of several pressure plates 7 abut against the tops of several buffer springs 8. Each of the pressure plates 7 is threaded with a screw 9, and the screw 9 is rotatably connected to the bracket 2. A rotating assembly is located inside the bracket 2 and is used to drive several screws 9 to rotate.

[0029] In use, the user drives several screws 9 to rotate by rotating the component, so that several pressure plates 7 move up and down under the action of the threads of several screws 9. When several pressure plates 7 move down, several pressure plates 7 will compress several buffer springs 8 respectively, so that the user can control the elastic force of several buffer springs 8.

[0030] Example 3: This example provides an infrared drone for detecting hot spots on photovoltaic modules. In addition to the technical solutions described in the above examples, it also has the following technical features: the rotating component includes: A plurality of first gear slots 10 are formed in the bracket 2. A first bevel gear 11 and a second bevel gear 12 are rotatably connected in each of the plurality of first gear slots 10. The first bevel gear 11 and the second bevel gear 12 mesh with each other. The bottom ends of the plurality of first bevel gears 11 penetrate the inner wall of the plurality of first gear slots 10 and extend into the bracket 2 and are fixedly connected to the top ends of the plurality of screws 9 respectively. A plurality of second gear slots 13 are formed in the bracket 2, and a third bevel gear 14 and a fourth bevel gear 15 are rotatably connected in each of the plurality of second gear slots 13, and the third bevel gear 14 and the fourth bevel gear 15 mesh with each other. Several through slots 16 are formed in the bracket 2 and are respectively connected to several first gear slots 10 and several second gear slots 13. Each of the several through slots 16 is rotatably connected to a connecting rod 17, and the two ends of the several connecting rods 17 extend into the several first gear slots 10 and several second gear slots 13 respectively and are fixedly connected to several second bevel gears 12 and several third bevel gears 14 respectively. A plurality of first rotating grooves 18 are respectively opened on the bottom surface of the inner wall of a plurality of second gear grooves 13. A first gear 19 is rotatably connected in each of the plurality of first rotating grooves 18, and the top of each of the plurality of first gears 19 extends into the plurality of second gear grooves 13 and is fixedly connected to a plurality of fourth bevel gears 15. The second rotating groove 20 is opened in the bracket 2 and is connected to several first rotating grooves 18. A second gear 21 is rotatably connected in the second rotating groove 20 and meshes with several first gears 19. A rotating rod 22 is fixedly connected to the bottom surface of the second gear 21, and one end of the rotating rod 22 passes through the inner wall of the second rotating groove 20 and extends to the outside.

[0031] In operation, the user manually rotates the rotating rod 22, causing the second gear 21 to rotate within the second rotating groove 20. This causes the second gear 21 to drive several first gears 19 to rotate within several first rotating grooves 18. The first gears 19 then drive several fourth bevel gears 15 to rotate within several second gear grooves 13. The fourth bevel gears 15 then drive several third bevel gears 14 to rotate. The third bevel gears 14, through several connecting rods 17, drive several second bevel gears 12 to rotate within several first gear grooves 10. When the second bevel gears 12 rotate, they drive several first bevel gears 11 to rotate within several first gear grooves 10. When the first bevel gears 11 rotate, they drive several screws 9 to rotate, ensuring that the user can simultaneously rotate several screws 9.

[0032] Example 4: This example provides an infrared drone for detecting hot spots on photovoltaic modules. In addition to the technical solutions of the above examples, it also has the following technical features and includes: The first pressing block 23 is fixedly connected to the bottom surface of the bracket 2, and the first pressing block 23 is located on one side of the rotating rod 22; The fixing block 24 is fixedly connected to the bottom surface of the bracket 2 and is located on the other side of the rotating rod 22. The fixing block 24 has a limiting groove 25 that communicates with the outside. A sliding rod 26 is slidably connected in the limiting groove 25. One end of the sliding rod 26 is fixedly connected to a second pressing block 27. An adjustment component is located within the fixed block 24 and is used to move the slide bar 26.

[0033] In use, the user adjusts the component to move the slide bar 26 along the limiting groove 25, which in turn moves the second pressing block 27. This allows the second pressing block 27 and the first pressing block 23 to clamp and fix the rotating rod 22, ensuring that the rotating rod 22 will not be affected by external factors and thus further improving the stability of the overall device.

[0034] Example 5: This example provides an infrared drone for detecting hot spots on photovoltaic modules. In addition to the technical solutions described in the above examples, it also has the following technical features: the adjustment component includes: Bolt 28 is threaded into slide bar 26; The third rotating groove 29 is formed on the inner wall of the limiting groove 25 and is connected to the outside. A rotating block 30 is rotatably connected in the third rotating groove 29, and one end of the rotating block 30 extends into the limiting groove 25 and is fixedly connected to the bolt 28.

[0035] In use, the user manually rotates the rotating block 30, causing one end of the rotating block 30 to drive the bolt 28 to rotate within the slide rod 26. This causes the slide rod 26 to move along the limiting groove 25 under the action of the bolt 28 thread, ensuring that the user can control the movement of the slide rod 26.

[0036] Example 6: This example provides an infrared drone for detecting hot spots in photovoltaic modules. In addition to the technical solutions of the above examples, it also has the following technical features: the bolt 28 is located in the limiting groove 25 and is rotatably connected to the limiting groove 25; one end of the rotating block 30 is rotatably connected to the limiting groove 25; and anti-slip textures are provided on the periphery of the rotating block 30.

[0037] Specifically, it is ensured that when the bolt 28 rotates, the bolt 28 can rotate normally within the limiting groove 25, and it is also ensured that when the rotating block 30 rotates, one end of the rotating block 30 can rotate normally within the limiting groove 25. At the same time, because the rotating block 30 is provided with anti-slip texture on its periphery, when the user rotates the rotating block 30 by hand, the anti-slip texture on the periphery of the rotating block 30 will reduce the possibility of hand slippage.

[0038] Example 7: This example provides an infrared drone for detecting hot spots in photovoltaic modules. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on several screws 9 have the same direction of rotation and the same thread pitch; the bottom ends of several first bevel gears 11 are rotatably connected to the bracket 2; and the rotating rod 22 is rotatably connected to the bracket 2.

[0039] Since the threads on the screws 9 have the same direction of rotation and the same thread pitch, when the screws 9 rotate, the pressure plates 7 will be acted upon by the threads of the screws 9, and move up and down simultaneously. This ensures that when the first bevel gears 11 rotate, the bottom ends of the first bevel gears 11 can rotate normally within the bracket 2. At the same time, it ensures that when the rotating rod 22 rotates, the rotating rod 22 can rotate normally within the bracket 2.

[0040] Example 8: This example provides an infrared drone for detecting hot spots in photovoltaic modules. In addition to the technical solutions of the above examples, it also has the following technical features: the two ends of the connecting rod 17 are rotatably connected to the first gear groove 10 and the second gear groove 13, respectively, and the top end of the first gear 19 is rotatably connected to the second gear groove 13.

[0041] Specifically, it is ensured that when the connecting rod 17 rotates, both ends of the connecting rod 17 can rotate normally in the first gear groove 10 and the second gear groove 13 respectively, and it is also ensured that when the first gear 19 rotates, the top end of the first gear 19 can rotate normally in the second gear groove 13.

[0042] Working principle: In use, the user manually rotates the rotating rod 22, causing the rotating rod 22 to drive the second gear 21 to rotate within the second rotating groove 20. This causes the second gear 21 to drive several first gears 19 to rotate within several first rotating grooves 18. The several first gears 19 then drive several fourth bevel gears 15 to rotate within several second gear grooves 13. The several fourth bevel gears 15 then drive several third bevel gears 14 to rotate. The several third bevel gears 14, through several connecting rods 17, drive several second bevel gears 12 to rotate within several first gear grooves 10. When the several second bevel gears 12 rotate, they drive several first bevel gears 11 to rotate within several first gear grooves 10. When the bevel gear 11 rotates, several first bevel gears 11 will drive several screws 9 to rotate, causing several pressure plates 7 to move up and down under the action of the threads of several screws 9. When several pressure plates 7 move downward, several pressure plates 7 will compress several buffer springs 8, allowing the user to control the elasticity of several buffer springs 8. When the UAV 1 faces a large landing speed or irregular ground impact, several buffer feet 6 will contact the ground first. When several buffer feet 6 contact the ground, the impact generated by landing will be initially reduced. At the same time, several buffer feet 6 will squeeze several buffer springs 8 through several sliders 5, thereby further reducing the impact generated by landing and ensuring that the overall device can be provided with buffering capacity. In use, the user manually rotates the rotating block 30, causing one end of the rotating block 30 to drive the bolt 28 to rotate within the slide rod 26. This causes the slide rod 26 to move along the limiting groove 25 under the action of the bolt 28 thread, which in turn causes the slide rod 26 to drive the second pressing block 27 to move. This allows the second pressing block 27 and the first pressing block 23 to clamp and fix the rotating rod 22, ensuring that the rotating rod 22 will not be affected by external factors and thus further improving the stability of the overall device.
