Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation devices, and more specifically, to a rooftop concentrating photovoltaic power generation device. Background Art

[0002] Photovoltaic power generation technology has become very popular and can be installed in many locations with good lighting. Photovoltaic power generation devices installed on the roof of a house are not easily blocked by high buildings and have higher power generation efficiency. However, for some special roofs, such as the insulation layer of a triangular slope, the inclined roof often has the problem of time-limited lighting. For example, in the morning, the photovoltaic power generation device on one side has good lighting and high power generation efficiency, while the other side has very low power generation efficiency due to the lack of light. In the afternoon, the situation may be reversed. For the same photovoltaic power generation component, there is always the problem of poor lighting.

The photovoltaic power generation components on either side of the roof are symmetrically distributed about the centerline of the focusing mechanism. The device relates to the field of photovoltaic power generation. This rooftop concentrating photovoltaic power generation device, based on research and analysis of existing issues with rooftop photovoltaic power generation, has been designed to enable multi-faceted focusing and adapt to temperature differences caused by focusing.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Example 1, see Figures 1-4This embodiment provides a rooftop concentrating photovoltaic power generation device, comprising: a roof 1; a tilting reflector 5, the tilting reflector 5 being mounted on the top of the roof 1; an electric telescopic rod 6, the electric telescopic rod 6 being mounted on the top of the roof 1; a fixing block 7, the fixing block 7 being mounted on the top of the roof 1; a movable reflector 8, the movable reflector 8 being mounted on the top of the roof 1; and a photovoltaic panel 9, the photovoltaic panel 9 being mounted on the top of the roof 1. The back side of the fixed block 7 is rotatably connected to the first rotating rod 21 through a bearing, the movable reflector 8 is fixedly sleeved on the outer wall of the first rotating rod 21, the top of the fixed block 7 is rotatably connected to the anemometer 22 through a bearing, the outer wall of the first rotating rod 21 is slidably connected to a connecting plate 210, the side of the connecting plate 210 is fixedly connected to a second spring 211, the side of the second spring 211 is fixedly connected to a first ratchet disk 212, the outer wall fixed sleeve of the first rotating rod 21 is provided with a second ratchet disk 213, the outer wall fixed sleeve of the first rotating rod 21 is provided with an extrusion plate 10, and the top of the roof 1 is equipped with a transmission assembly for transmitting the anemometer 22 and the first ratchet disk 212. By assembling key components such as the tilting reflector 5, the movable reflector 8, the photovoltaic panel 9, etc. on the top of the roof 1, and utilizing structures such as the fixed block 7, the first rotating rod 21, the anemometer 22 and the transmission assembly to achieve automatic adjustment of the reflector angle. After sensing wind speed, anemometer 22 drives first and second ratchet discs 212 and 213 through a transmission assembly, driving first rotating rod 21 to rotate. This in turn adjusts the angle of movable reflector 8, ensuring that light is more accurately reflected onto photovoltaic panel 9 and improving photovoltaic power generation efficiency. This improves the device's automation level and enhances its adaptability to different wind direction conditions, thereby enhancing the stability and efficiency of photovoltaic power generation. The transmission assembly includes a slide bar 218, which is fixedly connected to the back of the fixed block 7. The back of the fixed block 7 is rotatably connected to the second rotating rod 23 via a bearing. The outer wall of the second rotating rod 23 is slidably connected to a movable ring 24. The outer wall of the movable ring 24 is hinged to a first movable rod 25. A ball 26 is hinged to the side of the first movable rod 25. A second movable rod 27 is hinged to the side of the ball 26. The second movable rod 27 is hinged to the outer wall of the first rotating rod 21. A push rod 28 is fixedly connected to the side of the movable ring 24. A first spring 29 is movably sleeved on the outer wall of the push rod 28. The rotation of the anemometer 22 is driven by the first bevel gear 214, the second bevel gear 215, and the pulley 217, which drives the second rotating rod 23 to rotate, thereby causing the movable ring 24 to slide along the second rotating rod 23. The linkage between the first movable rod 25, the ball 26, and the second movable rod 27 ultimately drives the first ratchet disc 212, thereby locking the movable reflector 8. The setting of the first spring 29 can buffer the impact force during the movement, ensure the smoothness of the transmission, and further improve the stability and reliability of the device. The push rod 28 is rotatably connected to the front of the connecting plate 210 through a bearing, and the connecting plate 210 is slidably connected to the outer wall of the slide bar 218. The bottom of the anemometer 22 is fixedly connected to the first bevel gear 214, and the back of the fixed block 7 is rotatably connected to the third rotating rod 216 through a bearing. The outer wall of the third rotating rod 216 is fixedly sleeved with a second bevel gear 215. The outer wall of the third rotating rod 216 and the outer wall of the second rotating rod 23 are connected by a pulley 217. The bottom of the anemometer 22 is fixedly connected to the first bevel gear 214. By meshing with the second bevel gear 215, the rotation of the anemometer 22 is transmitted to the third rotating rod 216, and then connected to the second rotating rod 23 through the pulley 217, finally achieving the locking of the first rotating rod 21.The first bevel gear 214 and the second bevel gear 215 are meshed with each other, and two ends of the first spring 29 are fixedly connected to the side surface of the moving ring 24 and the side surface of the connecting plate 210 respectively.

[0028] When the above-mentioned device is used, the electric telescopic rod 6 rises to drive the extrusion plate 10 to rotate, and the extrusion plate 10 drives the first rotating rod 21 to rotate, and the first rotating rod 21 drives the movable reflector 8 to rotate, which is used to adjust and prop up the movable reflector 8 to be tilted. When the light itself is tilted at a large angle and the light on the other side is very weak, the light can be irradiated on the surface of the photovoltaic panel 9. When encountering a storm, the storm drives the anemometer 22 to rotate, and the anemometer 22 rotates to drive the first bevel gear 214 to rotate, the first bevel gear 214 drives the second bevel gear 215 to rotate, the second bevel gear 215 drives the third rotating rod 216 to rotate, the third rotating rod 216 drives the pulley 217 to rotate, the pulley 217 drives the second rotating rod 23 to rotate, and the second When the rotating rod 23 rotates, the centrifugal force causes the ball 26 to move outward, and the ball 26 drives the first movable rod 25 to move toward the back, and the first movable rod 25 drives the movable ring 24 to move toward the back, and the movable ring 24 drives the push rod 28 to move toward the back. When the push rod 28 moves toward the back, the first spring 29 is squeezed, and the push rod 28 pushes the connecting plate 210 to move toward the back, and the connecting plate 210 slides on the outer wall of the slide rod 218. At the same time, the connecting plate 210 drives the second spring 211 to move toward the back, and the second spring 211 drives the first ratchet disk 212 to move toward the back until the first ratchet disk 212 engages with the second ratchet disk 213, thereby limiting the first rotating rod 21, so that the movable reflector 8 will not be damaged due to rotation during a storm.

[0029] Example 2, see Figures 1-6On the basis of the first embodiment, a rotating device 3 for folding the tilting reflector 5 is installed on the top of the roof 1. When the tilting reflector 5 needs to be folded or unfolded, the rotating device 3 is driven to rotate the tilting reflector 5 around its hinge point to achieve folding or unfolding. This design is convenient for protecting the tilting reflector 5 in bad weather or when it is not needed to prevent it from being damaged. It also facilitates the installation, maintenance and transportation of the device, and improves the adaptability and flexibility of the device. The rotating device 3 includes a slide 37, which is fixedly connected to the front of the tilting reflector 5. A slide groove 38 is provided on the front of the roof 1. The slide 37 is slidably connected to the inner wall of the slide groove 38. When the tilting reflector 5 is folded or unfolded, the slide 37 slides in the slide groove 38 to play a guiding and limiting role, ensuring that the folding and unfolding process of the tilting reflector 5 is smooth and accurate. This structural design simplifies the complexity of the rotating device 3, reduces manufacturing costs, and improves the stability and reliability of the device. A first hydraulic reservoir 31 is fixedly connected to the top of the roof 1. A first hydraulic rod 32 is slidably connected to a piston at one end of the first hydraulic reservoir 31. A gear block 33 is fixedly connected to the bottom of the first hydraulic rod 32. The tilting mirror 5 is hinged to the top of the roof 1 via a hinged rod 34. A circular gear 35 is fixedly sleeved on the outer wall of the hinged rod 34. A second hydraulic rod 36 is slidably connected to a piston at one end of the first hydraulic reservoir 31. The second hydraulic rod 36 is fixedly connected to the front of the connecting plate 210. The circular gear 35 and the gear block 33 mesh with each other. The second hydraulic rod 36 is fixedly connected to the front of the connecting plate 210, transmitting hydraulic power to the transmission assembly to achieve coordinated adjustment of the movable mirror 8 and the tilting mirror 5. This hydraulic drive method has the characteristics of high power and fast response, and can quickly and smoothly complete the folding action of the tilting mirror 5, thereby improving the degree of automation and operational convenience of the device.

[0030] When the above-mentioned equipment is in actual use, when the connecting plate 210 moves toward the back, it drives the second hydraulic rod 36 to move toward the back. During the movement of the second hydraulic rod 36 toward the back, the internal pressure of the first hydraulic tank 31 increases, driving the first hydraulic rod 32 to move to the right. The first hydraulic rod 32 drives the gear block 33 to move to the right. The gear block 33 drives the circular gear 35 to rotate counterclockwise. The circular gear 35 drives the articulated rod 34 to rotate. The articulated rod 34 drives the tilting reflector 5 to rotate. During the movement of the tilting reflector 5, the slide plate 37 is driven to slide on the inner wall of the slide groove 38, which is used to limit the moving trajectory of the tilting reflector 5.

[0031] Example 3, see Figures 1-9On the basis of the first embodiment, the top of the roof 1 is equipped with a limiting device 4 for improving the stability of the movable reflector 8 when encountering wind. The limiting device 4 includes a second hydraulic tank 41, which is fixedly connected to the top of the first hydraulic tank 31. The piston at one end of the second hydraulic tank 41 is slidably connected to the third hydraulic rod 42, and the third hydraulic rod 42 is fixedly connected to the back of the second hydraulic rod 36. The inner wall of the first rotating rod 21 is fixedly connected to the airbag 43, and the outer wall of the airbag 43 is fixedly connected to the limiting rod 44. The front of the fixed block 7 is fixedly connected to the fixing rod 45, and the outer wall of the airbag 43 is fixedly connected to the connecting hose 46. The end of the connecting hose 46 away from the airbag 43 is fixedly connected to the top of the second hydraulic tank 41 to prevent it from excessive swinging or damage due to excessive wind force, thereby ensuring the stability of the movable reflector 8 during operation. This design effectively enhances the adaptability and reliability of the device in complex outdoor environments, ensuring the normal operation and power generation efficiency of the photovoltaic power generation device. When the movable reflector 8 is affected by wind, the gas in the airbag 43 enters the second hydraulic compartment 41 through the connecting hose 46, causing the third hydraulic rod 42 to slide in the second hydraulic compartment 41, thereby pushing the limit rod 44 to contact the fixed rod 45, limiting the swing of the movable reflector 8, enhancing the stability of the movable reflector 8 under strong wind conditions, and further improving the wind resistance and reliability of the device.

[0032] When the above-mentioned equipment is in actual use, when the second hydraulic rod 36 moves toward the rear side, it squeezes the third hydraulic rod 42. During the movement of the third hydraulic rod 42 toward the rear side, the internal pressure of the second hydraulic tank 41 increases, and the hydraulic oil is transferred to the airbag 43 through the connecting hose 46. After the airbag 43 expands, it drives the limit rod 44 on the outer wall to move outward, and is clamped on the outer wall of the fixed rod 45 through the gaps between the multiple limit rods 44, thereby improving the stability of the first rotating rod 21 and the movable reflector 8 when encountering wind.

[0033] When the above-mentioned device is used in a specific manner, the above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the scope of protection of the present invention.
