[0002] As the global demand for clean energy continues to grow, solar energy has gained widespread attention and application as a renewable energy technology. Solar photovoltaic panels provide people with a clean and sustainable source of energy by converting solar energy into electrical energy. In the prior art, solar photovoltaic panels are usually installed on the roof, wall or other supporting structures of a building through fixed components.

[0003] When using existing solar photovoltaic panel fixing components, the photovoltaic panels are fixed to the supporting frame by bolts. However, the existing solar photovoltaic panel fixing components cannot achieve corresponding adjustment of the angle of the photovoltaic panel, and thus cannot optimize the angle of receiving solar radiation, thereby limiting the maximum degree of solar radiation received by the photovoltaic panel in a day, thereby reducing the power generation efficiency and solar energy utilization rate. Secondly, it is impossible to assist in fixing and protecting the solar photovoltaic panels in bad weather, which will increase the risk of damage to the photovoltaic panels, such as being blown off by the wind or hit by hail, which will not only lead to a decrease in power generation efficiency, but also may cause equipment damage and safety hazards, increase maintenance and replacement costs, and affect the overall stability and reliability of the photovoltaic power generation system. Finally, it is impossible to clean the debris and dust on the outer surface of the solar photovoltaic panel, which will cause the surface of the photovoltaic panel to be blocked, affecting the absorption and conversion efficiency of sunlight, thereby reducing power generation and energy output.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1: Figure 1 and Figure 2 As shown, a fixing component of an embodiment of the present invention includes a fixing seat 1, the top of the fixing seat 1 is fixedly connected to a support frame 2, the inner surface of the support frame 2 is rotatably connected to a frame 3, one side of the support frame 2 and the top of the fixing seat 1 are jointly provided with a protective component 5, one side of the protective component 5 is provided with a cleaning component 6, the protective component 5 is used to adjust the angle of the frame 3 and to protect and assist in fixing the photovoltaic panel, and the cleaning component 6 is used to clean debris on the outer surface of the photovoltaic panel installed on the frame 3.

[0034] Specifically, after the fixing base 1 is effectively fixed to the relevant ground, the photovoltaic panel is installed on the frame 3, and then the frame 3 is adjusted in angle through the protection component 5, so that the photovoltaic panel on the frame 3 can change in angle. The protection component 5 can also be used to shield the outer surface of the photovoltaic panel in bad weather, and the cleaning component 6 can be used to effectively clean the dust attached to the outer surface of the photovoltaic panel during each shielding process.

[0035] like Figures 4 to 8As shown, the protective assembly 5 of this embodiment includes a rectangular box 51 fixedly connected to the top of the fixing seat 1 and one side of the supporting frame 2, and the limiting plates 52 are symmetrically fixedly connected to the two sides of the frame 3. An adjusting mechanism 53 is provided on one side of the inner surface of the rectangular box 51, and a hydraulic mechanism 54 is provided on the other side of the inner surface of the rectangular box 51. The inner surfaces of the two limiting plates 52 are both provided with fixing mechanisms 55, and the rear ends of the two limiting plates 52 are jointly provided with protective mechanisms 56.

[0036] like Figure 4 and Figure 5 As shown, the adjustment mechanism 53 of this embodiment includes a double-axis motor 531 fixedly connected to the inner surface of the rectangular box 51, one side output end of the double-axis motor 531 is fixedly connected to a threaded rod 532 through a coupling, the outer surface of the threaded rod 532 is threadedly connected to a slider 533 tightly attached to the inner surface of the rectangular box 51, the outer surface of the frame 3 is symmetrically fixedly connected to a gear 534 on both sides, and the slider 533 is symmetrically fixedly connected to a rack 535 meshing with the gear 534 on both sides.

[0037] Specifically, when the angle of the frame 3 needs to be adjusted, the output end of one side of the dual-axis motor 531 is started to drive the threaded rod 532 to rotate through the coupling. Since the threaded rod 532 and the slider 533 are threadedly connected, the threaded rod 532 drives the slider 533 to move during the rotation, so that the two racks 535 move. Since the rack 535 and the gear 534 are meshingly connected, the gear 534 drives the photovoltaic panel on the frame 3 to rotate in angle, so that the angle of the photovoltaic panel can be accurately and efficiently adjusted to adapt to different lighting conditions and improve the utilization efficiency of solar energy.

[0038] like Figure 4 and Figure 5 As shown, the hydraulic mechanism 54 of this embodiment includes an oil tank 541 fixedly connected to the inner surface of the rectangular box 51, the output end on the other side of the dual-axis motor 531 is fixedly connected to a threaded rod 542 through a coupling, the outer surface of the threaded rod 542 is threadedly connected to a slider 543 tightly attached to the inner surface of the rectangular box 51, the top of the slider 543 is fixedly connected to a push plate 544 slidably connected to the inner surface of the oil tank 541, one side of the inner surface of the oil tank 541 is symmetrically fixedly connected to a connecting pipe 545, and the other side of the inner surface of the oil tank 541 is symmetrically fixedly connected to a connecting pipe 546.

[0039] like Figure 4 and Figure 6As shown, the fixing mechanism 55 of this embodiment includes a cylindrical block 551 fixedly connected to the inner surfaces of the two limit plates 52, the inner surfaces of the two cylindrical blocks 551 are slidably connected with piston rods 552, the outer surfaces of the two piston rods 552 are sleeved with springs 553, the two ends of the two springs 553 are respectively fixedly connected to the pistons on the piston rods 552 and the inner surfaces of the cylindrical blocks 551, the inner surfaces of the two cylindrical blocks 551 are fixedly connected to the outer surface of the connecting pipe 545, and the bottom ends of the two piston rods 552 are fixedly connected to the fixing plates 554.

[0040] Specifically, when it is necessary to assist in fixing the photovoltaic panel, the output end on the other side of the dual-axis motor 531 is started to drive the threaded rod 2 542 to rotate through the coupling. Since the threaded rod 2 542 and the slider 2 543 are threadedly connected, the threaded rod 2 542 drives the slider 2 543 to move during the rotation, so that the push plate 544 moves on the inner surface of the oil tank 541. At this time, the hydraulic oil in the oil tank 541 is pushed into the two cylindrical blocks 551 through the two connecting pipes 1 545. Under the action of the hydraulic oil, the two piston rods 552 are pushed toward the photovoltaic panel, so that the spring 1 553 is in a compressed state, and the fixing plate 554 on the piston rod 552 is squeezed on the top of the photovoltaic panel, so as to assist in fixing the photovoltaic panel. This can enhance the stability and safety of the photovoltaic panel and ensure that the photovoltaic panel can be firmly installed under various conditions.

[0041] It should be noted that the dual-axis motor 531 in this solution is a mature driving technology means and equipment in the prior art. In this solution, the couplings on both sides can rotate independently and can stop after rotating to a set number of circles. Its internal structure, connection method and principle will not be explained further.

[0042] like Figure 4 , Figure 7 and Figure 8 As shown, the protective mechanism 56 of this embodiment includes a circular groove 561 opened on the inner surface of the limiting plate 52, a circular groove block 562 is fixedly connected to one side of the two limiting plates 52, a fixing rod 563 is fixedly connected to the inner surface of the circular groove block 562, a spring 564 is fixedly connected to the outer surface of the fixing rod 563, and a protective cloth 565 is fixedly connected to one end of the spring 564, a sliding groove 568 is opened on the side of the inner surface of the two limiting plates 52 close to each other, and a sliding rod 566 fixedly connected to one side of the protective cloth 565 is slidably connected to the inner surfaces of the two sliding grooves 568, a spring 2 569 is fixedly connected to one side of the inner surface of the two circular grooves 561, one end of the two springs 2 569 is fixedly connected to a piston block 5610 slidably connected to the inner surface of the circular groove 561, one side of the two piston blocks 5610 is fixedly connected to a pull rope 567 fixedly connected to one side of the sliding rod 566, and the inner surfaces of the two circular grooves 561 are fixedly connected to the outer surface of the connecting pipe 2 546.

[0043] Specifically, when the push plate 544 pushes the hydraulic oil into the connecting pipe 1 545, the hydraulic oil in the circular groove 561 is extracted through the connecting pipe 2 546 and enters the oil tank 541. Under the action of the positive and negative pressure difference, the piston block 5610 slides toward the direction of the oil tank 541 under the compression reaction force of the spring 2 569, thereby driving the pull rope 567 to tighten, pulling the slide bar 566 to slide on the inner surface of the slide groove 568, and pulling the protective cloth 565 to cover the photovoltaic panel. At this time, the spring 564 is in a deformed state, and can cooperate with the fixing mechanism 55. It can not only assist in fixing the photovoltaic panel through the fixing mechanism 55 in severe weather to enhance stability, but also can simultaneously achieve shielding and protection of the photovoltaic panel, reduce wind resistance and damage risks, improve the safety and protection of the photovoltaic panel, and ensure its durability and service life under severe weather conditions, thereby ensuring the continuous and stable operation of the photovoltaic power generation system.

[0044] Embodiment 2: Figure 4 , Fig. 9 and Fig.10 As shown, compared with the first embodiment, in order to clean the outer surface of the photovoltaic panel body 4, the cleaning component 6 of this embodiment includes an L-shaped plate 61 fixedly connected to one side of the rectangular box 51, a cleaning mechanism 63 is provided at the top end of the L-shaped plate 61, and a cleaning mechanism 62 is provided at the bottom end of the sliding rod 566.

[0045] like Figure 4 , Fig. 9 and Fig.10 As shown, the cleaning mechanism 62 of this embodiment includes two fixed blocks 621 fixedly connected to the bottom end of the sliding rod 566, the inner surfaces of the two fixed blocks 621 are rotatably connected to a cleaning roller 622, the inner surface of the limiting plate 52 is symmetrically fixedly connected to a rack 2 624, and the outer surface of the cleaning roller 622 is symmetrically fixedly connected to a gear 2 623 meshing with the rack 2 624.

[0046] Specifically, when it is necessary to clean the dust attached to the outer surface of the photovoltaic panel, the slide bar 566 will drive the cleaning roller 622 to move during the movement. Since the gear 2 623 and the rack 2 624 are meshingly connected, the gear 2 623 can rotate during the movement, thereby driving the cleaning roller 622 to rotate and effectively clean the debris and dust on the outer surface of the photovoltaic panel. This not only improves the cleaning efficiency of the photovoltaic panel and reduces the cost and difficulty of manual cleaning, but also ensures that the surface of the photovoltaic panel is always kept clean, thereby improving the power generation efficiency and overall performance of the photovoltaic panel, and providing a strong guarantee for the stable operation of the photovoltaic power generation system.

[0047] like Figure 4 and Fig.10As shown, the cleaning mechanism 63 of this embodiment includes a water collection frame 631 fixedly connected to the top of the L-shaped plate 61, a filter screen 632 is fixedly connected to the inner surface of the water collection frame 631, a connecting pipe three 633 is fixedly connected to the inner surface of the water collection frame 631, and a solenoid valve 634 is fixedly installed on the upper end of the connecting pipe three 633.

[0048] Specifically, the water collection frame 631 can also collect rainwater on rainy days and filter it through the filter net 632. Before or after cleaning, the cleaning roller 622 can control the rainwater through the connecting pipe three 633 to spray out the outer surface of the photovoltaic panel through the control of the solenoid valve 634 to rinse the outer surface of the photovoltaic panel. This not only improves the cleaning effect of the photovoltaic panel, makes full use of rainwater resources, but also reduces the water resource consumption during the cleaning process. At the same time, it simplifies the cleaning process and improves the convenience and efficiency of photovoltaic panel maintenance.

[0049] It should be noted that the solenoid valve 634 is a mature control technology means and equipment in the prior art. In this solution, it is used to control the flow direction of the liquid, and its internal structure, principle and connection method will not be explained again.

[0050] It should be noted that the connecting pipe three 633 is made of soft material. In actual use, the connecting pipe three 633 can be fixed on the outer surface of the circular groove block 562, and the height of the water accumulation frame 631 is always higher than the height of the photovoltaic panel.

[0051] The solar photovoltaic panel includes a photovoltaic panel body 4 , which is fixedly mounted on the top of the frame 3 .

[0052] Working principle: during use, when the angle of the frame 3 needs to be adjusted, the output end of one side of the dual-axis motor 531 is started to drive the threaded rod 1 532 to rotate through the coupling. Since the threaded rod 1 532 and the slider 1 533 are threadedly connected, the threaded rod 1 532 drives the slider 1 533 to move during the rotation process, so that the two racks 1 535 move. Since the rack 1 535 and the gear 1 534 are meshingly connected, the gear 1 534 drives the photovoltaic panel on the frame 3 to rotate in angle;

[0053] When it is necessary to assist in fixing the photovoltaic panel, the output end of the other side of the dual-axis motor 531 is started to drive the threaded rod 2 542 to rotate through the coupling. Since the threaded rod 2 542 and the slider 2 543 are threadedly connected, the threaded rod 2 542 drives the slider 2 543 to move during the rotation, so that the push plate 544 moves on the inner surface of the oil tank 541. At this time, the hydraulic oil in the oil tank 541 is pushed into the two cylindrical blocks 551 through the two connecting pipes 1 545. Under the action of the hydraulic oil, the two piston rods 552 are pushed toward the photovoltaic panel, so that the spring 1 553 is in a compressed state, and the fixing plate 554 on the piston rod 552 is squeezed on the top of the photovoltaic panel, and the push plate 544 When the hydraulic oil is pushed into the connecting pipe 1 545, the hydraulic oil in the circular groove 561 is drawn into the oil tank 541 through the connecting pipe 2 546. Under the action of the positive and negative pressure difference, the piston block 5610 slides toward the direction of the oil tank 541 under the compression reaction force of the spring 2 569, thereby driving the pull rope 567 to be tightened, pulling the slide bar 566 to slide on the inner surface of the slide groove 568, and pulling the protective cloth 565 to cover the photovoltaic panel. At this time, the clockwork 564 is in a deformed state, and can cooperate with the fixing mechanism 55, not only can the fixing mechanism 55 be used to assist in fixing the photovoltaic panel in bad weather to enhance stability, but also can simultaneously achieve shielding protection for the photovoltaic panel;

[0054] When it is necessary to clean the dust attached to the outer surface of the photovoltaic panel, the slide bar 566 will drive the cleaning roller 622 to move during the movement. Since the gear 2 623 and the rack 2 624 are meshingly connected, the gear 2 623 can realize self-rotation during the movement, thereby driving the cleaning roller 622 to rotate and effectively clean the debris and dust on the outer surface of the photovoltaic panel. The water accumulation frame 631 can also collect rainwater on rainy days and filter it through the filter net 632. Before or after the cleaning roller 622 cleans, the rainwater can be sprayed out through the connecting pipe three 633 under the control of the solenoid valve 634 to rinse the outer surface of the photovoltaic panel.
