Description

Technical Field

[0001] This invention belongs to the field of power maintenance equipment technology, and more specifically, relates to a photovoltaic power station maintenance drone. Background Technology

[0002] A photovoltaic (PV) power station is a power generation system that utilizes solar energy, employs specialized materials such as crystalline silicon panels and electronic components like inverters, and connects to the power grid to transmit electricity. It can be divided into stand-alone power generation systems with batteries and grid-connected power generation systems without batteries. Solar power generation is divided into concentrated solar power (CSP) and photovoltaic (PV). Currently, commercially available solar power refers to solar photovoltaic (PV) power generation. PV power generation products are mainly used in three areas: first, providing power to areas without electricity; second, solar-powered consumer electronics, such as various solar chargers, solar streetlights, and solar lawn lights; and third, grid-connected power generation. Currently, grid-connected PV power generation has gradually become an important part of the power supply system.

[0003] On the one hand, because photovoltaic power stations operate outdoors year-round, dust gradually accumulates on the surfaces of photovoltaic panels and other components during operation, affecting the reception of solar radiation and resulting in power generation losses. Simultaneously, dust accumulation can form hot spots on the component surfaces, impacting the lifespan of the photovoltaic modules. Therefore, it is necessary to clean the surfaces of photovoltaic panels and other components to remove dust. On the other hand, the condition of photovoltaic panels and other components needs frequent monitoring and inspection. Therefore, if comprehensive maintenance is required during the operation of a photovoltaic power station, a significant amount of manpower is needed.

[0004] Currently, there are precedents for using specialized drones for the operation, maintenance, and protection of photovoltaic power plants. These drones leverage their flexibility, ease of operation, and manpower-saving characteristics, carrying cameras or detectors to monitor and perform other maintenance tasks. This significantly reduces manpower costs, simplifies maintenance, and provides a new approach to photovoltaic power plant maintenance. However, current drones are limited to simple monitoring and surveillance tasks. They are still unable to handle other maintenance tasks such as cleaning photovoltaic panels, repelling intruders, and transporting maintenance tools, thus not fully meeting the daily maintenance needs of photovoltaic power plants. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic power plant maintenance drone to solve the technical problem that existing drones cannot fully meet the daily maintenance needs of photovoltaic power plants.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a photovoltaic power station maintenance drone is provided, including a drone body, a mounting base, a buffer fastener, and an equipment mounting frame. The mounting base is fixed to the lower part of the drone body; the buffer fastener is connected to the mounting base; the equipment mounting frame is provided with a hanging part for fastening into the buffer fastener and for installing maintenance equipment.

[0007] In one possible implementation, based on the above technical solutions, the equipment mounting frame is a plate-shaped or planar frame structure, and it is provided with a mounting structure for installing maintenance equipment.

[0008] In one possible implementation, based on the above technical solutions, the mounting base is bonded, welded, or connected to the unmanned aerial vehicle body via fasteners.

[0009] In one possible implementation, based on the above technical solutions, the equipment mounting frame is provided with multiple hanging parts, and there are multiple buffer fasteners, which are set one-to-one with the hanging parts.

[0010] In one possible implementation, based on the above technical solutions, the buffer fastener includes a hook, a sealing member, a lower buffer body, and an upper buffer body. One end of the hook is connected to the mounting base; one end of the sealing member is hinged to the free end of the hook, and the other end is detachably connected to the end of the hook connected to the mounting base, so as to seal the hook portion; the lower buffer body is disposed inside the hook portion of the hook and has a groove capable of accommodating the hanging piece; the upper buffer body is disposed on the sealing member and is used to enter the groove when the sealing member closes the hook portion of the hook, so as to press the hanging piece tightly into the groove.

[0011] In one possible implementation, based on the above technical solutions, the upper buffer body is an elastic rubber block, and the sealing member is connected to the end of the mounting base by snapping, plugging, or fasteners.

[0012] In one possible implementation, based on the above technical solutions, the lower buffer body includes a rigid connecting plate, an elastic shell, and a non-Newtonian fluid filler. Both the rigid connecting plate and the elastic shell are U-shaped structures. The rigid connecting plate is connected to the inner side of the hook portion of the hook. The elastic shell is located inside the rigid connecting plate and is fixedly connected to it. The groove is formed inside the elastic shell, and a cavity is provided inside the elastic shell. The non-Newtonian fluid filler fills the cavity.

[0013] In one possible implementation, in conjunction with the above technical solutions, the lower buffer body further includes an air bladder and an air duct. The air bladder is located inside the cavity and connected to the bottom of the cavity. One end of the air duct passes through the elastic shell and communicates with the air bladder, while the other end communicates with the air duct of the adjacent lower buffer body.

[0014] In one possible implementation, based on the above technical solutions, the cavity inside the elastic shell is a long, narrow cavity, and the airbag is a long, narrow structure with its two ends connected to the two ends of the cavity, respectively.

[0015] In one possible implementation, in conjunction with the above technical solutions, the photovoltaic power station maintenance drone further includes an air pressure control component, which is connected to the air duct.

[0016] The beneficial effects of the photovoltaic power station maintenance drone provided by this invention are as follows: Compared with the prior art, this invention facilitates the installation and replacement of various maintenance equipment through the cooperation of the mounting base, buffer fasteners and equipment mounting frame. At the same time, the cooperation of the buffer fasteners and hanging parts can also reduce vibration between the drone body and the maintenance equipment, reduce the transmission of vibration, and reduce the mutual interference between drone flight and maintenance operations. Ultimately, this enables the drone to carry various maintenance equipment for maintenance operations, greatly increasing the types of maintenance operations that the drone can perform, which is conducive to saving manpower and improving the maintenance efficiency of photovoltaic power stations.

[0037] The photovoltaic power plant maintenance drone provided by this invention will now be described.

[0038] like Figure 1 As shown, the first embodiment of the present invention provides a photovoltaic power station maintenance drone, including a drone body 10, a mounting base 20, a buffer fastener 30, and an equipment mounting frame 40. The mounting base 20 is fixed to the lower part of the drone body 10; the buffer fastener 30 is connected to the mounting base 20; the equipment mounting frame 40 is provided with a hanging part 41 for fastening in the buffer fastener 30 and for installing maintenance equipment 60.

[0039] When in use, first fix the mounting base 20 and buffer fastener 30 to the drone body 10, then connect the maintenance equipment 60 to the equipment mounting frame 40, then hang the hanger 41 on the equipment mounting frame 40 on the buffer fastener 30, and then start the drone body 10 to perform maintenance operations.

[0040] Compared with the prior art, the photovoltaic power station maintenance drone provided in this embodiment facilitates the installation and replacement of various maintenance equipment through the cooperation of the mounting base 20, buffer fastener 30 and equipment mounting frame 40. At the same time, the cooperation of the buffer fastener 30 and the hanging part 41 can also reduce vibration between the drone body 10 and the maintenance equipment 60, reduce the transmission of vibration, and reduce the mutual interference between drone flight and maintenance operation. Ultimately, the drone can carry various maintenance equipment to carry out maintenance operations, greatly increasing the types of maintenance operations that the drone can perform, which is conducive to saving manpower and improving the maintenance efficiency of photovoltaic power stations.

[0041] like Figure 1 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0042] The maintenance equipment 60 can be any equipment that may be used for the maintenance of a photovoltaic power station. It can be a cleaning device such as a water sprayer or a brush washing component, or a device such as an audible and visual alarm to drive away intruders such as birds, or a tool storage rack or other tool transport equipment.

[0043] like Figure 1 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0044] The equipment mounting frame 40 is a plate-shaped or flat frame structure, and is equipped with mounting holes, buckles, hinge seats and other mounting structures for installing and maintaining equipment 60.

[0045] like Figure 1 and Figure 3 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0046] The mounting base 20 is fixedly connected to the unmanned aerial vehicle body 10 by bonding, welding, or fasteners.

[0047] like Figure 1 and Figure 4 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0048] The equipment mounting frame 40 is equipped with multiple hanging parts 41 and multiple buffer fasteners 30, which are set one-to-one with the hanging parts 41 to maintain balance.

[0049] like Figures 1 to 3As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0050] The buffer fastener 30 includes a hook 31, a sealing member 32, a lower buffer body 34, and an upper buffer body 33. One end of the hook 31 is connected to the mounting base 20. One end of the sealing member 32 is hinged to the free end of the hook 31, and the other end is detachably connected to one end of the hook 31 connected to the mounting base 20 to seal the hook portion of the hook 31. The lower buffer body 34 is located inside the hook portion of the hook 31 and has a groove 35 that can accommodate the hanging member 41. The upper buffer body 33 is located on the sealing member 32 and is used to enter the groove 35 when the sealing member 32 closes the hook portion of the hook 31 to press the hanging member 41 tightly into the groove 35.

[0051] like Figures 1 to 3 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0052] The upper buffer body 33 is an elastic rubber block, and the sealing part 32 is connected to the hook 31 by a snap-fit, plug-in or fastener-connected connection at one end of the mounting base 20.

[0053] like Figure 3 As shown, in a specific embodiment, the free end of the sealing member 32 is provided with a sliding cavity and a ball 321. The part where the hook 31 connects to the sealing member 32 is provided with a slot. The front end of the ball 321 engages with the slot, and the rear end of the ball 321 slides with the sliding cavity. A spring 323 is provided inside the sliding cavity, and the spring 323 provides an outward pushing force to the ball 321 so that when the sealing member 32 closes the hook of the hook 31, the ball 321 is kept in the slot to prevent the sealing member 32 from opening. The ball 321 is provided with a toggle handle 322 so that when it is necessary to open the sealing member 32, the ball 321 can be removed from the slot by toggle the handle 322. In order to maintain the firmness of the engagement between the ball 321 and the slot, the sliding direction of the ball 321 is in the same direction as the depth direction of the slot. The slot can be directly provided on the hook 31 or on the rigid connecting plate 341 of the lower buffer body 34.

[0054] like Figures 1 to 3 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0055] The upper buffer 33 can also be a hollow elastic block filled with a non-Newtonian fluid, so as to cooperate with the lower buffer 34 to buffer and dissipate energy.

[0056] like Figures 1 to 3 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0057] The lower buffer body 34 includes a rigid connecting plate 341, an elastic shell 342, and a non-Newtonian fluid filler 343. Both the rigid connecting plate 341 and the elastic shell 342 are U-shaped structures. The rigid connecting plate 341 is connected to the inner side of the hook of the hook 31. The elastic shell 342 is located inside the rigid connecting plate 341 and is fixedly connected to the rigid connecting plate 341. A groove 35 is formed inside the elastic shell 342. A cavity is provided inside the elastic shell 342, and the non-Newtonian fluid filler 343 is filled in the cavity.

[0058] Non-Newtonian fluid filler 343 is formed by filling with non-Newtonian fluids. Non-Newtonian fluids are fluids that do not satisfy Newton's law of viscosity, meaning the relationship between their shear stress and shear strain rate is not linear. Non-Newtonian fluids are widely present in daily life, production, and nature. Concentrated solutions and suspensions of polymers are generally non-Newtonian fluids. Polyethylene, polyacrylamide, polyvinyl chloride, nylon 6, PVS, celluloid, polyester, rubber solutions, various engineering plastics, and melts and solutions of chemical fibers are all non-Newtonian fluids. Petroleum, mud, coal-water slurry, ceramic slurry, pulp, paint, ink, toothpaste, silkworm silk regeneration solution, well cleaning and completion fluids used in drilling, magnetic slurry, coatings for certain photosensitive materials, foam, liquid crystals, high-sediment-content water flows, debris flows, and the Earth's mantle are also non-Newtonian fluids. Various slurry-like food materials in the food industry, such as tomato juice, starch solution, egg white, apple pulp, and concentrated sugar water, are also non-Newtonian fluids.

[0059] The rigid connecting plate 341 can form a good connection with the hook of the hook 31, providing strong support for the elastic shell 342 and preventing the elastic shell 342 from being twisted under force. The elastic shell 342 and the non-Newtonian fluid filler 343 can play a role in shock absorption and energy dissipation. When vibration occurs between the UAV body 10 and the equipment mounting frame 40, the elastic shell 342 can play a buffering role by utilizing its own elasticity and the internal pressure of the non-Newtonian fluid. The non-Newtonian fluid can harden or liquefy during vibration, which has a strong energy absorption effect and greatly reduces the transmission of vibration energy. Preferably, the non-Newtonian fluid filler 343 is a shear-liquefied non-Newtonian fluid, so that it can remain in a hardened state during slight vibration, avoiding excessive relative displacement between the UAV body 10 and the equipment mounting frame 40. At the same time, it can liquefy during severe vibration, increasing displacement to buffer and dissipate energy, so that more mechanical energy is converted into heat energy and reducing the transmission of vibration.

[0060] like Figures 1 to 3 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0061] The lower buffer 34 also includes an air bladder 344 and an air duct 345. The air bladder 344 is located inside the cavity and connected to the bottom of the cavity. One end of the air duct 345 passes through the elastic shell 342 and communicates with the air bladder 344, while the other end communicates with the air duct 345 of the adjacent lower buffer 34. By setting up interconnected air bladders 344, the pressure balance within the elastic shells 342 on all the buffer fasteners 30 can be maintained to ensure good shock resistance. When the elastic shell 342 is compressed, the gas inside the air bladder 344 can maintain elasticity and allow the non-Newtonian fluid filling body 343 to undergo greater deformation, thus buffering and dissipating energy and quickly balancing the force.

[0062] like Figures 1 to 3 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0063] The cavity inside the elastic shell 342 is an elongated cavity, and the airbag 344 is an elongated structure with its two ends connected to the two ends of the cavity. This allows the airbag 344 to be evenly distributed within the elastic shell 342, which facilitates greater deformation of the non-Newtonian fluid filler 343 in more directions, thus providing buffering and energy dissipation for a rapid response to pressure changes.

[0064] like Figure 4 As shown, based on the first embodiment, the present invention provides another specific embodiment as follows:

[0065] The photovoltaic power plant maintenance drone also includes an air pressure control component 50, which is connected to an air duct 345 to regulate and balance the air pressure inside the airbag 344.

[0066] In one specific embodiment, the air pressure control component 50 is a rigid housing equipped with an inflation valve and an deflation valve, and is connected to the mounting base 20.

[0067] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
