Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power station inspection, and in particular to a photovoltaic thermal inspection device based on an unmanned aerial vehicle. Background Art

[0002] Photovoltaic power generation, as an important form of renewable energy power generation, accounts for a large proportion of renewable energy power generation. Compared with centralized photovoltaic power generation, distributed photovoltaic power sources are on the user side, and power generation supplies local loads, which can effectively reduce dependence on grid power supply and reduce line losses. In the process of photovoltaic power station inspection, drone inspection lines are often required. During the inspection process, a drone equipment for photovoltaic power station inspection is required to conduct multi-angle observation.

[0003] During the inspection process, the camera on one side of the drone records and observes, so the camera only swings up and down, which makes the camera's observation range small during the inspection process. Secondly, if the observation position and direction need to be changed, the drone needs to be controlled to rotate and then stabilized before continuing to observe. This makes the video image easy to shake and easy to lose important inspection content.

[0004] An existing patent (publication number: CN220076697U) discloses a drone device for inspecting photovoltaic power stations. If the observation position and direction need to be changed, this utility model only needs to rotate the camera with internal components, so that the camera has a larger observation range during the inspection process. If the observation position and direction need to be changed, there is no need to control the drone to rotate. The drone can inspect various angles during flight, and the video image is not prone to shaking, and important detection content is not easily lost.

[0005] In response to the above problems, existing patents have provided solutions, but the structure used to drive the camera to flip 90 degrees in the above patents is too complicated and requires a series of structures to be linked together. It is not only costly but also prone to failure. At the same time, the tripod used at the bottom of the drone body does not have the function of landing cushioning, so it is easy for the camera to vibrate due to excessive landing impact, which in turn causes damage to the camera.

[0006] To this end, a photovoltaic thermal inspection device based on drones is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide a photovoltaic thermal inspection device based on a drone, which can solve the problem that the structure used to drive the camera to flip 90 degrees in the above-mentioned patent is too complicated and requires a series of structures to be linked, which is not only costly but also prone to failure. At the same time, the tripod at the bottom of the drone body does not have the function of landing cushioning, so that the camera is easily vibrated due to excessive impact when landing, which in turn causes damage to the camera.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: a photovoltaic and thermal inspection device based on a drone, comprising a drone body, a rotating structure provided at the bottom of the drone body, a connecting plate bolted to the bottom of the rotating structure, a rotating mechanism provided on the left side of the bottom of the connecting plate, a carrying plate bolted to the inner side of the rotating mechanism, a camera provided inside the carrying plate, and a slow-descent mechanism provided on the outer side of the drone body;

[0009] The rotating mechanism includes a cavity frame bolted to the left side of the bottom of the connecting plate, a fixing seat bolted to the right side of the top side of the cavity frame, an electric push-pull rod rotatably connected to the inside of the fixing seat, an arc frame rotatably connected to the bottom side of the cavity frame, the left side of the arc frame rotatably connected to the telescopic end of the electric push-pull rod, and the right side of the top of the arc frame bolted to the left side of the bottom of the supporting plate.

[0010] Preferably, the slow-descent mechanism includes brackets bolted to the four outer corners of the drone body, and a telescopic rod is fixedly connected to the inner side of the bottom of the bracket.

[0011] Preferably, a buffer spring is provided on the outer side of the telescopic rod, and the top of the buffer spring is fixedly connected to the inner side of the bottom of the bracket.

[0012] Preferably, a grounding plate is bolted to the bottom of the telescopic rod, and the top of the grounding plate contacts the bottom of the buffer spring.

[0013] Preferably, the rotating structure includes a fixing plate bolted to the bottom of the drone body, and a servo motor is fixedly connected to the inner side of the bottom of the fixing plate.

[0014] Preferably, the output end of the servo motor is bolted to a shaft, the bottom of the shaft is bolted to a connecting disk, and the bottom of the connecting disk is bolted to the top of the connecting plate.

[0015] Preferably, a docking structure is provided on the right side of the bottom of the supporting plate, and the docking structure comprises a docking rod bolted to the right side of the top of the supporting plate, and a magnet sheet is embedded in the inner side of the top of the docking rod.

[0016] Preferably, a magnetic block is fixedly connected to the right side of the bottom of the connecting plate, and the magnetic block is magnetically connected to the magnet sheet.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This application sets up a rotation mechanism, using only a few components such as a cavity frame, a fixed seat, an electric push-pull rod, and an arc frame. The electric push-pull rod is extended and retracted to drive the arc frame to rotate, thereby enabling the carrier plate to achieve a 90-degree flip. This simple structure reduces costs and reduces the risk of failure of linkage components. It can effectively improve the reliability and stability of camera rotation, ensuring that the camera can flexibly adjust the shooting angle during photovoltaic and thermal inspections, thereby improving the inspection effect.

[0019] 2. This application provides a slow-descent mechanism to effectively cushion the impact of the drone landing, preventing the impact force from being directly transmitted to the camera and causing vibration damage, thereby protecting the camera and other components and extending the service life of the equipment. At the same time, it also enhances the stability of the drone body during landing, reduces the risk of damage to the fuselage and tipping caused by landing impact, and ensures the subsequent normal use and flight performance of the equipment.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] A photovoltaic and thermal inspection device based on a drone includes a drone body 1, a rotating structure 2 is provided at the bottom of the drone body 1, a connecting plate 3 is bolted to the bottom of the rotating structure 2, a rotating mechanism 4 is provided on the left side of the bottom of the connecting plate 3, a supporting plate 5 is bolted to the inner side of the rotating mechanism 4, a camera 6 is provided inside the supporting plate 5, and a slow-down mechanism 7 is provided on the outer side of the drone body 1;

[0030] The rotating mechanism 4 includes a cavity frame 401 bolted to the left side of the bottom of the connecting plate 3, a fixing seat 402 is bolted to the right side of the top side inside the cavity frame 401, an electric push-pull rod 403 is rotatably connected to the inside of the fixing seat 402, an arc frame 404 is rotatably connected to the bottom side of the cavity frame 401, the left side inside the arc frame 404 is rotatably connected to the telescopic end of the electric push-pull rod 403, and the right side of the top of the arc frame 404 is bolted to the left side of the bottom of the supporting plate 5.

[0031] In this embodiment: the connecting plate 3 can be rotated 360 degrees in the horizontal direction through the rotating structure 2, thereby driving the rotating mechanism 4 and camera 6 below to change the horizontal observation angle and expand the inspection range. The rotating mechanism 4 uses the telescopic movement of the electric push-pull rod 403 to cleverly drive the arc frame 404 to rotate, thereby driving the supporting plate 5 and camera 6 to achieve a 90-degree flip. The operation is simple and direct. Compared with the complex linkage structure, it effectively reduces the cost, reduces the probability of failure, and improves the stability and reliability of the equipment operation. The descent mechanism 7 plays a key role when the drone body 1 lands, effectively buffering the impact force when landing, avoiding excessive impact force from being transmitted to the camera 6, and preventing the camera 6 from being damaged by vibration. At the same time, it ensures the stability of the overall structure of the drone body 1, ensuring that the performance of the equipment is not affected after multiple inspection tasks, extending the service life of the equipment, and improving the efficiency and quality of the entire photovoltaic thermal inspection operation.

[0032] Specifically, such as Figure 5 As shown, the slow-descent mechanism 7 includes brackets 701 bolted to the four outer corners of the drone body 1, and a telescopic rod 702 is fixedly connected to the inner side of the bottom of the bracket 701.

[0033] Specifically, such as Figure 5As shown, a buffer spring 703 is provided on the outer side of the telescopic rod 702 , and the top of the buffer spring 703 is fixedly connected to the inner side of the bottom of the bracket 701 .

[0034] Specifically, such as Figure 5 As shown, a grounding plate 704 is bolted to the bottom of the telescopic rod 702 , and the top of the grounding plate 704 contacts the bottom of the buffer spring 703 .

[0035] In this embodiment: by setting up a slow-descent mechanism 7, during the landing process of the drone body 1, when the ground plate 704 first contacts the ground, the impact force will cause the telescopic rod 702 to contract, and at this time the buffer spring 703 is compressed. The buffer spring 703 uses its elastic potential energy to absorb and disperse the impact force, effectively reducing the vibration transmitted to the drone body 1 and the camera 6. The bracket 701 is firmly connected to the four corners of the outer side of the drone body 1 to ensure that a uniform buffering effect can be provided in all directions. This structural design can significantly reduce the risk of damage to the camera 6 due to excessive landing impact, while protecting the overall structure of the drone body 1, extending the service life of the equipment, and improving the stability and reliability of the equipment during multiple take-offs and landings.

[0036] Specifically, such as Figure 4 As shown, the rotating structure 2 includes a fixing plate 201 bolted to the bottom of the drone body 1 , and a servo motor 202 is fixedly connected to the inner side of the bottom of the fixing plate 201 .

[0037] Specifically, such as Figure 4 As shown, the output end of the servo motor 202 is bolted to a shaft 203 , the bottom of the shaft 203 is bolted to a connecting disk 204 , and the bottom of the connecting disk 204 is bolted to the top of the connecting plate 3 .

[0038] In this embodiment: by setting up a rotating structure 2, the servo motor 202 is used as a power source, and its output end drives the shaft 203 to rotate, thereby rotating the connecting disk 204, and finally realizing 360-degree free rotation of the connecting plate 3 and all the components below in the horizontal direction. This allows the camera 6 to easily adjust the horizontal observation angle, comprehensively cover various areas of the photovoltaic power station, improve the flexibility and comprehensiveness of the inspection, and help improve the efficiency and accuracy of photovoltaic thermal inspections.

[0039] Specifically, such as Figure 6 As shown, a docking structure 8 is provided on the right side of the bottom of the supporting plate 5 , and the docking structure 8 includes a docking rod 801 bolted to the right side of the top of the supporting plate 5 , and a magnet sheet 802 is embedded inside the top of the docking rod 801 .

[0040] Specifically, such as Figure 6 As shown, a magnetic block 803 is fixedly connected to the right side of the bottom of the connecting plate 3 , and the magnetic block 803 is magnetically connected to the magnet sheet 802 .

[0041] In this embodiment: by setting a docking structure 8, when the supporting plate 5 is in a horizontal state, the magnet piece 802 on the top of the docking rod 801 and the magnetic block 803 at the bottom of the connecting plate 3 will attract each other and dock tightly. This magnetic connection method is simple and reliable. It can not only ensure the position stability of the supporting plate 5 during operation, but also prevent the camera 6 from affecting the shooting effect due to accidental shaking, thereby improving the overall practicality and reliability of the equipment, and helping to improve the performance of photovoltaic thermal inspection equipment in actual applications.

[0042] Working principle: When the photovoltaic thermal inspection equipment based on the drone is used for inspection operations, the servo motor 202 is operated, and the output end of the servo motor 202 drives the shaft 203 to rotate, and the shaft 203 drives the connecting plate 204 to rotate, so that the connecting plate 3 and the rotating mechanism 4 below, the supporting plate 5 and the camera 6 can achieve 360-degree free rotation in the horizontal direction. The operator can flexibly control the servo motor 202 as needed to adjust the horizontal observation angle of the camera 6 to ensure that it can fully cover all areas of the photovoltaic power station and accurately obtain the thermal information of the photovoltaic panels. When the vertical observation angle of the camera 6 needs to be adjusted, such as switching from horizontal shooting to vertical shooting, the electric push-pull rod 403 is started, and the electric push-pull rod 403 is extended and retracted, and its retractable end drives the arc frame 404 connected to it to rotate in the cavity frame 401. Since the top right side of the arc frame 404 is bolted to the bottom left side of the supporting plate 5, the rotation of the arc frame 404 will cause the supporting plate 5 and the camera 6 to flip 90 degrees around the connection point on the left. During the flipping process, the docking rod 801 top The magnetic piece 802 at the bottom will be disconnected from the magnetic block 803 on the right side of the bottom of the connecting plate 3. Then, during the flight, the camera 6 continuously collects thermal images of the photovoltaic panel and transmits the data back to the ground control station in real time via wireless transmission. The operator of the ground control station can monitor the image data in real time and analyze whether there is any thermal abnormality in the photovoltaic panel. When the inspection mission is completed, the drone body 1 returns to land. During the landing process, when the ground plate 704 first contacts the ground, the impact force will cause the telescopic rod 702 to contract and the buffer spring 703 to be compressed. The buffer spring 703 uses its elastic potential energy to absorb and disperse the impact force, effectively reducing the vibration transmitted to the drone body 1 and the camera 6. The stable connection of the bracket 701 at the four corners of the outside of the drone body 1 ensures that a uniform buffering effect can be provided in all directions, protects the overall structure of the drone body 1, reduces the risk of damage to the camera 6 due to excessive impact when landing, extends the service life of the equipment, and ensures the stability and reliability of the equipment during multiple take-offs and landings, so that the next inspection mission can be carried out smoothly.
