Solar energy refers to the thermal radiation energy of the sun, which is mainly manifested in the so-called sunlight. In modern times, it is generally used to generate electricity or provide energy for water heaters. Solar cells are also called "solar chips" or "photovoltaic cells".

DETAILED DESCRIPTION

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] Example 1 See also Figure 1-Figure 9 The steel structure support for photovoltaic power generation shown in the figure includes a base 1, a supporting mechanism 4, an adjusting mechanism 8, a cleaning mechanism 11 and two groups of photovoltaic panels 2. The base 1 is rotatably connected with a first electric telescopic rod 3. The base 1 is provided with a rotating member 41 for driving the bottom end of the first electric telescopic rod 3 to rotate and adjust. The rotating member 41 can be driven by a motor to rotate. The supporting mechanism 4 includes two groups of guide frames 5 installed on the upper side of the base 1. The telescopic end of the first electric telescopic rod 3 is fixedly connected with a first rotating shaft 6. The first rotating shaft 6 is rotatably connected with a connecting plate 42. The two groups of photovoltaic panels 2 are rotatably connected to the two sides of the connecting plate 42 respectively. A guide member 7 for guiding movement in the guide frame 5 is provided on the side of the photovoltaic panel 2 away from the connecting plate 42, which is used to drive the connecting plate 42 to rise and fall through the first electric telescopic rod 3, so that the photovoltaic panel 2 can be rotated, flipped and retracted.

[0020] The adjusting mechanism 8 includes a mounting ring 9 movably sleeved with the outer wall of the first electric telescopic rod 3, and two groups of second electric telescopic rods 10 are rotatably connected to the mounting ring 9, and the telescopic ends of the second electric telescopic rods 10 are connected to the guide frame 5. The adjusting mechanism 8 also includes two groups of connecting rods 27 fixedly installed between the two ends of the two groups of guide frames 5, and the telescopic ends of the second electric telescopic rods 10 are fixedly connected with second rotating shafts 28. The connecting rods 27 are rotatably connected to the second rotating shafts 28, and are used to adjust the angle of the guide frame 5 through the second electric telescopic rod 10, thereby changing the overall inclination angle of the photovoltaic panel 2 and improving the light receiving efficiency. The cleaning mechanism 11 includes two groups of cleaning rollers 12 installed on the guide frame 5, which are used to clean the surface of the photovoltaic panel 2 when the first electric telescopic rod 3 drives the photovoltaic panel 2 to flip, and at the same time, the cleaning rollers 12 are self-cleaned through the connecting plate 42.

[0021] The guide member 7 includes four groups of guide blocks 13 which are respectively slidably connected to the inner walls of the guide frames 5 on both sides; a first spring 14 is fixedly connected between the two groups of guide blocks 13 in the same guide frame 5; a rotating rod 15 which is rotatably connected to the guide block 13 is fixedly connected to the side surface of one end of the photovoltaic panel 2 away from the connecting plate 42; a side plate 40 is fixedly connected to the side surface of one end of the photovoltaic panel 2 away from the connecting plate 42; a lifting member 16 is provided on the guide frame 5, which is used to enable the first electric telescopic rod 3 to drive the guide frame 5 and the photovoltaic panel 2 to be lifted and lowered as a whole when the guide frame 5 is in a tilted state.

[0022] The lifting member 16 includes a device box 17 fixedly installed on the side of the guide frame 5, a device groove 18 is opened in the device box 17, a clamping block 19 is slidably connected in the device groove 18, a second spring 20 fixedly connected to the device groove 18 is fixedly connected to one side of the clamping block 19, an electromagnet 21 is fixedly connected in the device box 17, and a control member 22 for sensing the horizontal state of the guide frame 5 and controlling the operating state of the electromagnet 21 is provided on the guide frame 5. The control member 22 includes a control frame 23 fixedly installed at the bottom of the guide frame 5, an arc groove 24 is opened in the control frame 23, a ball 25 is rollingly connected in the arc groove 24, and a control key 26 for controlling the power supply status of the electromagnet 21 is fixedly connected to the bottom of the control frame 23.

[0023] In the present embodiment, in the initial state, the connecting plate 42 and the photovoltaic panels 2 on both sides are in the same horizontal plane. At this time, the guide blocks 13 on both sides are at the two end positions of the guide frame 5. The extended lengths of the second electric telescopic rods 10 on both sides are the same, which can ensure that the guide frame 5 is in a horizontal state. By adjusting the telescopic lengths of the second electric telescopic rods 10 on both sides, the inclination angle of the guide frame 5 and the photovoltaic panel 2 as a whole can be adjusted, so that the photovoltaic panels 2 on both sides are combined into a whole and tilted. The first electric telescopic rod 3 is driven by the rotating member 41 to rotate the connecting plate 42 and the photovoltaic panel 2 together to adjust the direction, so that the photovoltaic panel 2 can receive light energy toward the illuminated position. At this time, since the guide frame 5 is in a tilted state, the ball 25 is offset in the arc groove 24 and no longer conflicts with the control key 26. The electromagnet 21 is powered off, so that the second spring 20 pops out the clamping block 19, and the clamping block 19 limits the guide blocks 13 on both sides, so that the guide blocks 13 cannot slide in the guide frame 5, thereby realizing the limiting of the positions of the photovoltaic panels 2 on both sides and improving the stability during the adjustment process.

[0024] By driving the first rotating shaft 6 through the first electric telescopic rod 3 to lift the connecting plate 42, the photovoltaic panels 2 and the guide frame 5 on both sides can be lifted and lowered as a whole. At this time, since the guide block 13 is limited, the position of the photovoltaic panel 2 is fixed. At the same time, the length of the second electric telescopic rod 10 on both sides is fixed. The lifting and lowering of the connecting plate 42 can synchronously drive the guide frame 5, the second electric telescopic rod 10 and the mounting ring 9 to lift and lower together, so that the photovoltaic panel 2 in an inclined state can be height-adjusted, which is convenient for creating a height difference between adjacent photovoltaic panels 2 and reducing light obstruction.

[0025] When encountering bad weather, first control the second electric telescopic rods 10 on both sides to extend and retract, adjust the guide frame 5 to a horizontal state, and the ball 25 rolls to the bottom of the middle of the arc groove 24, triggering the control key 26 to energize the electromagnet 21, and the electromagnet 21 absorbs the magnetic material of the clamping block 19 to slide in the device groove 18, and the clamping block 19 releases the clamping of the guide block 13. Thereafter, the first electric telescopic rod 3 is controlled to retract, which can drive the connecting plate 42 to make the photovoltaic panels 2 on both sides flip downward, and the photovoltaic panel 2 drives the rotating rod 15 to rotate while making the guide block 13 slide in the guide frame 5, compressing the first spring 14. During this process, the side plate 40 flips with the photovoltaic panel 2. When the photovoltaic panel 2 rotates to a vertical state, the side plate 40 just rotates to a horizontal state and closes at the top position to prevent rainwater, sand and gravel and other materials from entering between the photovoltaic panels 2 on both sides, thereby improving the protection performance of the surface of the photovoltaic panel 2.

[0026] It is worth noting that when the first electric telescopic rod 3 lifts up or pulls back the photovoltaic panel 2 to an inclined state, the second electric telescopic rods 10 on both sides can still drive the guide frame 5 and the photovoltaic panel 2 to rotate and adjust as a whole, so as to achieve the diversity of flipping and better receive light at different angles. When the first electric telescopic rod 3 drives the photovoltaic panel 2 to move up and flip, the cleaning roller 12 will be linked to clean the surface of the photovoltaic panel 2, and the cleaning roller 12 will be self-cleaned through the connecting plate 42. The device has a compact structure, convenient and efficient installation, and can flip the photovoltaic panels 2 on both sides at multiple angles, thereby reducing the impact and corrosion of external substances such as rainwater on the photovoltaic panel 2, extending the service life of the photovoltaic panel 2, and at the same time, it can realize the self-cleaning function of the surface of the photovoltaic panel 2 during the flipping process, reduce the hindrance of stains to light energy conversion, and improve the power generation efficiency.

[0027] Example 2 See also Figure 1-Figure 9 Embodiment 2 is described. This embodiment further describes Embodiment 1. The cleaning mechanism 11 shown in the figure also includes a sliding frame 29 fixedly mounted on the upper side of the guide frame 5. Two groups of first sliding blocks 30 and second sliding blocks 31 are slidably connected in the sliding frames 29 on both sides. One side of the first sliding block 30 and the second sliding block 31 are respectively fixedly connected with a third spring 32 fixedly connected to the sliding frame 29. A threaded rod 33 is threadedly connected on the second sliding block 31. The threaded rod 33 passes through the first sliding block 30 and the cleaning roller 12, and is movably connected to the inner wall of the first sliding block 30 and the cleaning roller 12. A cleaning member 34 for self-cleaning the cleaning roller 12 is provided on the connecting plate 42.

[0028] The cleaning member 34 includes a cleaning shaft 35 installed on a connecting plate 42, a collecting groove 36 is provided on the connecting plate 42, both ends of the cleaning shaft 35 are rotatably connected to the collecting groove 36, the outer wall of the cleaning shaft 35 can be in contact with the outer walls of the cleaning rollers 12 on both sides for transmission, and a collecting member 37 for collecting dust in the collecting groove 36 is provided on the mounting ring 9. The collecting member 37 includes a vacuum cleaner 38 fixedly installed on the mounting ring 9, and the input end of the vacuum cleaner 38 is connected to a hose 39 fixedly connected to the bottom of the connecting plate 42, and the top of the hose 39 is connected to the collecting groove 36.

[0029] In this embodiment, when the guide frame 5 is in a horizontal state, the first electric telescopic rod 3 is started to lift up, and the cleaning rollers 12 on both sides can be pushed to both sides through the cleaning shaft 35. At the same time, the connecting plate 42 drives the photovoltaic panels 2 on both sides to flip upward, and the cleaning rollers 12 roll to both sides on the surface of the photovoltaic panel 2. As the photovoltaic panel 2 continues to flip, the cleaning rollers 12 complete the comprehensive cleaning of the upper surface of the photovoltaic panel 2. During this process, the first sliding block 30 and the second sliding block 31 slide to both sides in the sliding frame 29, compressing the third spring 32, so that the surface of the cleaning roller 12 always has a force that resists the upper surface of the photovoltaic panel 2, thereby improving the cleaning intensity.

[0030] When the photovoltaic panel 2 is in a horizontal state, the third springs 32 on both sides push the first sliding block 30 and the second sliding block 31 so that the cleaning roller 12 and the outer wall of the cleaning shaft 35 in the middle fit each other. At this time, the cleaning shaft 35 is started to rotate, which can drive the cleaning roller 12 to rotate, and the dust on the outer wall of the cleaning roller 12 is removed by friction. At the same time, the dust is sucked by the vacuum cleaner 38, and the dust can be drawn into the vacuum cleaner 38 through the collecting groove 36 and the hose 39 for collection. When replacing, the threaded rod 33 can be unscrewed from the second sliding block 31 and pulled out from the cleaning roller 12, so that the cleaning roller 12 can be replaced and repaired.
