Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and particularly to distributed photovoltaic power stations located on rooftops. Background Technology

[0002] With the vigorous promotion of new energy sources, more and more rural areas are starting to install photovoltaic panels on their roofs to generate electricity using solar energy. These distributed photovoltaic power stations can not only meet the electricity needs of rural households, but also feed excess electricity into the power grid to achieve energy recycling and utilization, bringing additional economic benefits to farmers. At the same time, they reduce dependence on traditional fossil fuels, resulting in good economic and environmental benefits.

[0003] However, when actually installing a distributed photovoltaic power station, maintenance or cleaning requires climbing onto the roof, which not only poses safety issues, but also makes climbing difficult because rural houses may be single-story or tiled, and the roof shapes are not uniform.

[0004] Therefore, it is necessary to propose distributed photovoltaic power stations located on rooftops to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a distributed photovoltaic power station located on a rooftop to solve the problem of climbing work required when maintaining and cleaning distributed photovoltaic power stations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distributed photovoltaic power station located on a rooftop, comprising: A photovoltaic power station component, comprising a photovoltaic panel and a guide rail, wherein the guide rails are arranged in pairs and installed on the roof of a building; both sides of the photovoltaic panel are connected to a fixed frame, and a sliding plate is fixedly installed at the end of the fixed frame away from the photovoltaic panel, the sliding plate being slidably disposed in the guide rail; Both the photovoltaic panels and the guide rails are assembled. Multiple guide rails are installed end-to-end on the roof to form a "two"-shaped track. Multiple photovoltaic panels form a long rectangular plate, and the multiple photovoltaic panels in the long rectangular plate slide simultaneously in the "two"-shaped track. Pull rings are fixedly connected to the slide plates at both ends of the "two"-shaped track. The pull rings are used to install connecting ropes.

[0008] Preferably, an upper base plate is fixedly disposed on the upper surface of the fixed frame, the upper base plate is located on the upper surface of the guide rail, and a first cleaning cotton plate is fixedly disposed on the lower surface of the upper base plate, the lower surface of the first cleaning cotton plate being movably attached to the upper surface of the guide rail. As the photovoltaic panel moves along the length of the guide rail, the first cleaning cotton board wipes the upper surface of the guide rail.

[0009] Preferably, the inner side of the fixing frame is provided with a slot, and the end of the photovoltaic panel is engaged in the slot. The slide plate is provided with a guide component, which includes a first guide wheel and a second guide wheel. Multiple first guide wheels and multiple second guide wheels are provided. The multiple second guide wheels are distributed on the upper and lower surfaces of the slide plate. The first guide wheels are distributed on the side of the slide plate away from the fixing frame. When the photovoltaic panel moves along the length direction of the guide rail, the second guide wheels and the first guide wheels roll along the inner wall of the guide rail.

[0010] Preferably, a rubber connecting pad is fixedly provided at one end of the slide plate, and a mounting plate is fixedly connected to the end of the rubber connecting pad. The mounting plate is fixedly installed on an adjacent slide plate by screws. When the photovoltaic panel is pulled and moved by the pull rope, the adjacent photovoltaic panels can bend and adapt due to the elastic deformation of the rubber connecting pad.

[0011] Preferably, a fixed chuck is installed on the bottom wall of the house, and a first winding device is provided at the end of the pull rope, which is engaged in the fixed chuck. When pulling the rope, two people need to pull the rope on both sides at the same time. The two people operate the two first winding devices respectively. The one pulling upward uses the first winding device to wind up the rope, and the one being pulled uses the first winding device to loosen the rope.

[0012] Preferably, an electrical box is installed on the roof of the house, and the electrical box is connected to the photovoltaic panel by a wire, which is wound up in a second winder; When the photovoltaic panel is pulled to the ground, the wire in the second rewinder is automatically unwound to adapt to the change in the position of the photovoltaic panel.

[0015] Preferably, a water tank is installed on the top of the house, and a water pump is connected to the water tank. The water pump is connected to a water pipe, and the water pipe is connected to a water inlet channel.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention, through the combination of guide rail and pull rope design, eliminates the need for climbing operations. Simply pull the pull rope from the ground to bring the photovoltaic panels to the ground for maintenance and cleaning, reducing the number of times you need to climb and lowering the operational risks. 2. In this invention, users can operate the cleaning themselves, and pulling the pull rope in the opposite direction can also pull the photovoltaic panels on the ground into the guide rail for installation, reducing the burden on power workers and making maintenance simple and convenient; 3. The distributed photovoltaic power station on the roof in this invention is not only suitable for single-story houses, but also for rooftops. When the photovoltaic power station components are installed on tiled roofs, the photovoltaic panels can still be maintained by pulling ropes. 4. The present invention is provided with a first cleaning cotton board and a second cleaning cotton board, which wipe the upper surface of the guide rail and the surface of the photovoltaic panel respectively, which can reduce impurities on the surface of the guide rail and prevent impurities from falling on the surface of the photovoltaic panel and affecting the photovoltaic power generation efficiency. In addition, water in the water tank can be pumped out through the water pipe, water inlet channel, water inlet chamber and water spray hole in sequence to soften and rinse stubborn stains on the surface of the photovoltaic panel. The cleaning effect is good and the cleaning cotton board can be used continuously for a long time. 5.

[0035] Example 1 This invention provides, for example Figures 1-14 The distributed photovoltaic power station shown on the rooftop can pull the photovoltaic panels 2 to the ground for maintenance and cleaning without the need for climbing, making it easy and safe.

[0036] Furthermore, the rooftop distributed photovoltaic power station allows for ground-based cleaning of the photovoltaic panel 2 and guide rail 3 surfaces, eliminating the need for climbing operations, reducing the frequency of climbing operations, and increasing safety.

[0037] refer to Figures 1-2 As shown, the distributed photovoltaic power station on the roof includes a photovoltaic power station component 1, which includes a photovoltaic panel 2 and a guide rail 3. The guide rails 3 are arranged in pairs, and each pair of guide rails 3 has a fixed edge 4 fixed on the side away from each other. The fixed edge 4 is provided with multiple fixing holes, and the fixed edge 4 is installed on the roof through the fixing holes. The photovoltaic panel 2 is connected to both sides of a fixing frame 8. A sliding plate 14 is fixedly provided at the end of the fixing frame 8 away from the photovoltaic panel 2, and the sliding plate 14 is slidably disposed in the guide rail 3.

[0038] refer to Figures 8-12Furthermore, in this rooftop distributed photovoltaic power station, the photovoltaic panels 2 and guide rails 3 are all assembled. Multiple guide rails 3 are installed end to end on the roof to form a "two"-shaped track. Multiple photovoltaic panels 2 form a long rectangular plate, and the multiple photovoltaic panels 2 in the long rectangular plate slide simultaneously in the "two"-shaped track. Pull rings 13 are fixedly connected to the slide plates 14 at both ends of the "two"-shaped track. The pull rings 13 are used to install connecting ropes 27. The two connecting ropes 27 on the same side of the "two"-shaped track are connected together by a pull rope 24. Guides 21 are installed on both sides of the exterior walls of the house (including bungalows 20 and tiled houses 28). Multiple guides 21 are provided. The multiple guides 21 are distributed along the height direction of the house, and the guides 21 are located at the center line of the length direction of the photovoltaic power station module 1. The side of the guide 21 away from the house is provided with a guide groove 29, and the pull rope 24 is movably installed in the guide groove 29.

[0039] refer to Figures 13-14 As shown, when it is necessary to maintain the photovoltaic power station module 1, there is no need to climb to a height. Simply pull the rope 24 on one side of the cart to make the photovoltaic panel 2 slide out of the guide rail 3, and then tighten the rope 24 on the other side to make the photovoltaic panel 2 gradually slide out of the guide rail 3 and be placed on the ground from the top of the building. This allows for maintenance of the photovoltaic power station module 1. It is simple and convenient to use and improves the safety of the operation.

[0040] The present invention utilizes the combined design of guide rail 3 and pull rope 24 to allow the photovoltaic panel 2 located on the house to be pulled to the ground. Pulling the pull rope 24 in the opposite direction can also pull the photovoltaic panel 2 on the ground into the guide rail 3 for installation. The operation is simple and convenient. When the photovoltaic panel 2 needs to be cleaned, the user can clean it himself, reducing the burden on power workers. Maintenance is simple and convenient. In actual use, monitoring devices such as cameras can be installed on the house to monitor the usage status of the photovoltaic panel 2 for convenient management.

[0041] When the photovoltaic power station module 1 is installed on the roof tile 28, the photovoltaic panel 2 can still be maintained by pulling the rope 24. It has a wide range of applications. The core structure of the rope 24 and the guide rail 3 in this invention is derived from the prior art of using ropes to pull objects to move them from high to low places. It is easy to implement, but the following safety precautions should be taken during use: First: Ensure that the materials of the pull rope 24 and the connecting rope 27 are safe and reliable. The pull rope 24 and the connecting rope 27 are made of polyester double braided rope with a diameter in the range of 2~5cm. They have excellent tensile strength, can withstand large pulling forces, have low elongation during use, and have stable length. This avoids the phenomenon of sudden drop in the elasticity of the photovoltaic panel 2 due to the pull rope 24 and the connecting rope 27, which could lead to safety accidents. They also have strong UV resistance, excellent wet storage performance, high strength in humid environments, and a soft feel with no torque, making them easy to operate and more suitable for outdoor use. Similarly, galvanized steel wire rope, carbon fiber rope, aramid fiber rope, etc. can be selected according to actual needs, which will not be elaborated here.

[0042] Second: Ensure the reliability of guide rail 3. The installation design of guide rail 3 needs to take into account the size and weight of photovoltaic panel 2. When installing guide rail 3, expansion screws need to be used to fix it to the roof to ensure a stable installation. Third: It is necessary to ensure that the photovoltaic panel 2 can smoothly enter and exit the guide rail 3. A rounded chamfer is designed at the end of the guide rail 3 to facilitate the entry and exit of the photovoltaic panel 2. It is not shown in the figure and is a common technology, so it will not be described in detail here.

[0043] refer to Figures 1-2 As shown, a side bracket 5 is fixedly installed on the guide rail 3, and a cleaning plate 6 is connected to the side bracket 5. The cleaning plate 6 is located above the photovoltaic panel 2. A second cleaning cotton plate 11 is fixedly installed on the bottom surface of the cleaning plate 6. The second cleaning cotton plate 11 is movably attached to the bottom surface of the photovoltaic panel 2. When the photovoltaic panel 2 moves in and out of the guide rail 3, the second cleaning cotton plate 11 can wipe away the stains on the surface of the photovoltaic panel 2. The surface of the photovoltaic panel 2 can be cleaned by pulling the pull rope 24 on the ground, which is convenient and practical.

[0044] Furthermore, an upper substrate 9 is fixedly disposed on the upper surface of the fixed frame 8. The upper substrate 9 is located on the upper surface of the guide rail 3. A first cleaning cotton board 10 is fixedly disposed on the lower surface of the upper substrate 9. The lower surface of the first cleaning cotton board 10 is movably attached to the upper surface of the guide rail 3. When the photovoltaic panel 2 moves along the length direction of the guide rail 3, the first cleaning cotton board 10 can wipe the upper surface of the guide rail 3, which can reduce impurities on the surface of the guide rail 3, keep the area around the photovoltaic panel 2 clean, and prevent impurities from falling on the surface of the photovoltaic panel 2 and affecting the photovoltaic power generation efficiency.

[0045] refer to Figures 3-7 As shown, a slot 12 is provided on the inner side of the fixed frame 8, and the end of the photovoltaic panel 2 is engaged in the slot 12. A guide component 15 is provided on the slide plate 14. The guide component 15 includes a first guide wheel 16 and a second guide wheel 17. Multiple first guide wheels 16 and multiple second guide wheels 17 are provided. Multiple second guide wheels 17 are distributed on the upper and lower surfaces of the slide plate 14. The first guide wheels 16 are distributed on the side of the slide plate 14 away from the fixed frame 8. When the photovoltaic panel 2 moves along the length direction of the guide rail 3, the second guide wheels 17 and the first guide wheels 16 roll along the inner wall of the guide rail 3, which plays a guiding role, so that the photovoltaic panel 2 can move smoothly.

[0046] Furthermore, a rubber connecting pad 19 is fixedly installed at one end of the slide plate 14, and an mounting plate 18 is fixedly connected to the end of the rubber connecting pad 19. The mounting plate 18 is fixedly installed on an adjacent slide plate 14 by screws. When the photovoltaic panel 2 is pulled and moved by the pull rope 24, the adjacent photovoltaic panels 2 can bend and adapt due to the elastic deformation of the rubber connecting pad 19, avoiding the phenomenon that multiple photovoltaic panels 2 are too long in a straight line and are easy to break and difficult to operate.

[0047] When one of the pull ropes 24 is pulled, the other pull rope 24 is attached to the guide groove 29, ensuring that the photovoltaic panel 2 can move in a straight line along the length of the guide rail 3. A fixed chuck 22 is also installed on the bottom wall of the house. The end of the pull rope 24 is provided with a first winding device 23, which is engaged in the fixed chuck 22. When the pull rope 24 is pulled, two people need to pull both pull ropes 24 at the same time. The two people operate the two first winding devices 23 respectively. The one pulling upward uses the first winding device 23 to wind up the pull rope 24, and the one being pulled uses the first winding device 23 to loosen the pull rope 24, ensuring that the photovoltaic panel 2 is stably pulled to the ground.

[0048] Furthermore, considering that the photovoltaic panel 2 needs to be used in conjunction with the electrical box 26, the electrical box 26 is fixedly installed on the roof of the house in this invention. The electrical box 26 and the photovoltaic panel 2 are connected by a sufficiently long wire. The wire is wound in the second winder 25. When the photovoltaic panel 2 is pulled to the ground, the wire in the second winder 25 is automatically unwound to adapt to the change in position of the photovoltaic panel 2.

[0049] It should be noted that both the first rewinder 23 and the second rewinder 25 use commercially available cable unwinding reels, which are common existing technologies and will not be described in detail here; the electrical box 26 contains common solar converters for converting solar energy into electrical energy, etc., which will not be described in detail here.

[0050] Example 2 refer to Figure 15 As shown, inclined surfaces 30 are provided on both sides of the upper substrate 9. When the upper substrate 9 moves along the surface of the guide rail 3, the debris on the surface of the guide rail 3 can be guided along the inclined surface 30 and fall onto the outside of the guide rail 3, without entering the surface of the photovoltaic panel 2. This further avoids the phenomenon of debris entering the surface of the photovoltaic panel 2 or entering the sliding connection between the photovoltaic panel 2 and the guide rail 3, causing jamming.

[0051] It should be noted that the first cleaning cotton board 10 and the second cleaning cotton board 11 have a large surface area and need to be maintained for a long time, so they need to be replaced regularly.

[0052] Example 3 refer to Figures 16-17As shown, a water inlet channel 34 is provided inside the side support 5, and a water inlet cavity 35 is provided inside the cleaning plate 6. The water inlet cavity 35 is connected to the water inlet channel 34. Multiple water spray holes 36 are provided on the bottom surface of the cleaning plate 6, and these holes are evenly distributed. The water spray holes 36 are connected to the inside of the water inlet cavity 35. A water tank 31 is installed on the top of the structure, and a water pump 32 is connected to the water tank 31. The water pump 32 is connected to a water pipe 33. Water is stored in tank 31. When water pump 32 is started, the water in tank 31 is pumped out through water pipe 33, water inlet channel 34, water inlet chamber 35 and water spray hole 36 in sequence. The water seeps out from the second cleaning cotton board 11 and acts on the surface of photovoltaic panel 2, softening the stubborn stains on the surface of photovoltaic panel 2. The cleaning effect is good. Also, due to the impact of water, the stains can be washed away from photovoltaic panel 2 and second cleaning cotton board 11, so that the second cleaning cotton board 11 can be used for a long time.

[0053] As an extension, if a solar water heater is installed on the roof, an extension pipe is installed on the water pump 32 to extend into the water intake chamber of the solar water heater. At a suitable temperature, the water pump 32 is used to extract hot water from the solar water heater to clean the surface of the photovoltaic panel 2, resulting in a better cleaning effect. Furthermore, in future research and development, it is possible to use the photovoltaic panel 2 to directly heat the water tank 31, eliminating the need for photovoltaic pipes on the water tank 31.

[0054] In summary, the rooftop distributed photovoltaic power station provided in this invention solves the problem of maintenance requiring climbing, and has a wide range of applications.
