Description

Technical Field

[0001] This utility model generally relates to the field of solar power generation, and more specifically, to a device for automatically and continuously cleaning solar photovoltaic panels and solar thermal reflectors. Background Art

[0002] Currently, my country has the world's largest installed capacity of solar energy, and solar energy has become my country's third largest source of electricity after thermal and hydropower. Guided by the policy direction of prioritizing new energy sources in power generation, the application of solar energy will continue to grow. Ground-mounted solar power stations mainly include photovoltaic (PV) and solar thermal power stations such as tower solar power stations. Routine maintenance has revealed that ground dust often covers the surface of solar panels, reducing power generation efficiency and affecting the station's revenue. Therefore, the surfaces of many solar panels require regular cleaning to remove dust and bird droppings. Current technologies often struggle with this. Existing water trucks are too large to fit into the array and can easily damage the solar panels. Using robotic rollers to move the solar panels can cause vibrations that may lead to microcracks in the silicon wafers, and the rollers can damage the frame of the solar panel components, affecting the panel's lifespan. Moving from one row of solar panels to another is difficult. Vacuum suction cups are slow and time-consuming, and require numerous components such as air pumps and suction cups.

[0003] Therefore, how to automatically, efficiently, and safely clean the surface of solar power plant panels to improve power generation efficiency is an urgent technical problem to be solved. Utility Model Content

[0034] like Figures 1 to 4 As shown, the dual-purpose cleaning device for solar power stations of this invention is used for automatic and continuous cleaning of the panels 6 of a solar power station. The panels 6 can be photovoltaic panels, solar thermal reflectors, or a combination of both. The panels 6 are fixedly installed by brackets 7, and their surfaces are typically tilted at a certain angle.

[0035] In this embodiment, the dual-purpose cleaning equipment for solar power plants includes a moving mechanism 1, a rotating mechanism 2, a lifting mechanism 3, an execution mechanism 4, and a cleaning mechanism 5. The moving mechanism 1 is movably positioned on the side of the plate 6 to be cleaned; the rotating mechanism 2 is mounted on the moving mechanism 1; the lifting mechanism 3 is mounted on the rotating mechanism 2 and can rotate horizontally under the drive of the rotating mechanism 2; the execution mechanism 4 is suspended and mounted on the lifting mechanism 3 and can rise and fall under the drive of the lifting mechanism 3; the cleaning mechanism 5 is mounted at the end of the execution mechanism 4 away from the lifting mechanism 3, and the cleaning mechanism 5 is used to clean the plate 6.

[0036] In this embodiment, the moving mechanism 1 is an electric vehicle. The moving mechanism 1 includes wheels 11 and a frame 12. The frame 12 moves under the drive of the wheels 11.

[0038] In this embodiment, the rotary mechanism 2 includes a first mating part 21 and a second mating part 22 that are rotatably engaged. The first mating part 21 is mounted on the chassis of the frame 12 of the moving mechanism 1, and the second mating part 22 is engaged with the first mating part 21 through a bearing and locked by a locking nut.

[0039] In this embodiment, a first thrust bearing 27 and a second thrust bearing 28 are respectively clamped at both ends of the axial fit between the first mating part 21 and the second mating part 22, and a sliding bearing 29 is clamped between the radial mating surfaces of the first mating part 21 and the second mating part 22, so that the first mating part 21 and the second mating part 22 can be positioned in the horizontal direction and rotated at the same time.

[0040] In this embodiment, a motor 23 and a reducer 24 are mounted on the second mating part 22, and a gear ring 26 is mounted on the first mating part 21.

During the rotation, the first thrust bearing 27 and the second thrust bearing 28 bear axial force, and the sliding bearing 29 bears radial load, making the relative rotation between the first mating part 21 and the second mating part 22 safer and more reliable.

[0041] In this embodiment, the lifting mechanism 3 includes a base 31, a lifting frame 32, a platform 33, and a drive cylinder 34.

The extension and retraction of the piston rod of the drive cylinder 34 drives the lifting frame 32 to extend and retract, causing the platform 33 to move up and down in the vertical plane.

[0042] In this embodiment, the actuator 4 is fixed above the lifting mechanism 3, with one end fixedly connected to the counterweight 8 and the other end connected to the cleaning mechanism 5 via the upright frame 42. The main body of the actuator 4 is a cantilever beam 41, with the counterweight 8 and the upright frame 42 connected to both ends of the cantilever beam 41, respectively.

A narrow through groove 44 is provided on the adjusting handle 43, and a locking member is provided on the cantilever beam 41. By adjusting the relative position of the narrow through groove 44 relative to the locking member, the angle of the cleaning mechanism 5 is adjusted. After the angle is determined, its posture is locked by the locking member.

[0043] In this embodiment, the cleaning mechanism 5 includes a disc brush 51, a connector 52, a motor 53, bearings 56 and 57, and a rotating shaft 55. The disc brush 51 is mounted on the connector 52 and has bristles 54 for cleaning the plate 6. The connector 52 is rotatably connected to the upright frame 42 via the rotating shaft 55, and is also hinged to the adjusting handle 43. Bearings 56 and 57 are positioned between the disc brush 51 and the connector 52, and are sleeved onto the rotating shaft 55. The motor 53 is driven by the disc brush 51 via the rotating shaft 55, and the rotating shaft 55 and the disc brush 51 are fixed together by a locking nut.

The water spraying mechanism 9 consists of a water tank 91, a water pump 92, a switch, a valve, a water pipe 93, and a nozzle 94. The water pump 92 is connected to the water tank 91. The water pipe 93 is arranged along the actuator 4, with one end connected to the water pump 92 and the other end connected to the nozzle 94. The nozzle 94 is located above the cleaning mechanism 5. The switch controls the opening and closing of the nozzle 94, the valve controls the water volume of the nozzle 94, and the water pump 92 is automatically controlled by the control system.

[0045] In this invention, the position of the actuator 4 is adjusted by the moving mechanism 1, the rotating mechanism 2 and the lifting mechanism 3, thereby driving the cleaning mechanism 5 to clean the surface of the plate 6. This will not cause vibration damage and can automatically, efficiently and safely clean the surface of the solar power station plate 6, thereby improving power generation efficiency and having very high market value.
