Description

Technical Field

[0001] This invention belongs to the field of photovoltaic and photothermal technology, and specifically relates to an adjustable solar photovoltaic and photothermal integrated device. Background Technology

[0002] An adjustable solar photovoltaic-thermal integrated device is a high-efficiency energy harvesting system that dynamically coordinates the photovoltaic and solar thermal outputs through mechanical structures or intelligent control methods. It can flexibly adjust its operating mode according to seasonal changes, weather conditions, and real-time energy demands from users. In summer, it enhances heat dissipation to ensure photovoltaic power generation efficiency, while in winter, it prioritizes heat preservation and collection. This proactive adjustment capability effectively solves the pain points of traditional solar systems, such as fixed electrical and thermal output and poor seasonal adaptability, thereby significantly improving the overall utilization rate of solar energy and achieving optimal temporal and spatial matching between energy production and demand.

[0003] An existing adjustable solar photovoltaic-thermal integrated device requires attention to spacing during use; otherwise, mutual shading may occur as the photovoltaic panels rotate to align with the sun. This necessitates a larger footprint, which in turn increases the length of the heat pipes, requiring better insulation and resulting in higher overall costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an adjustable solar photovoltaic-thermal integrated device.

[0005] The technical solution adopted to solve the above technical problems is: an adjustable solar photovoltaic-thermal integrated device, including a first base, lifting mechanisms on both sides of the first base, a third base at the end of the lifting mechanism away from the first base, a second base between the first base and the third base, a driving mechanism on the first base, the second base and the third base, a support frame fixedly connected to the upper surface of the first base, the second base and the third base, a fixed rod fixedly connected through the support frame, and a mounting seat rotatably connected to the fixed rod.

[0006] By using the above technical solutions, including lifting and driving mechanisms, photovoltaic panels can face the sun at any time, while reducing the footprint and significantly lowering operating costs, ensuring that they do not block each other.

[0007] Furthermore, a plurality of photovoltaic panels are fixedly connected to the upper surface of the mounting base, a plurality of brackets are fixedly connected to the mounting base, and heat pipes are fixedly connected through the brackets. The photovoltaic panels are arranged in a parabolic shape, the heat pipes are located at the focal point of the parabolic surface of the photovoltaic panels, and the two ends of the heat pipes are provided with connecting interfaces.

[0008] The above technical solution can focus solar energy onto the heat pipe through a photovoltaic panel, heating the liquid inside the heat pipe and achieving the integration of photovoltaic and solar thermal energy, which greatly improves the utilization efficiency of solar energy.

[0009] Furthermore, a hydraulic rod is rotatably connected to the lower surface of the second base, and a second fixing plate is fixedly connected to the end of the hydraulic rod away from the second base. The second fixing plate has several second fixing holes.

[0010] The above technical solution involves activating a hydraulic rod, which raises the second base. The second base then moves the third base upwards via a first and second connecting rod. Since the first, second, and third bases are all connected by the first and second connecting rods, which are parallel to each other, the third base remains parallel to the first base during lifting, preventing it from tilting. This improves overall stability, prevents the photovoltaic panels from obstructing each other, reduces the required floor space, and lowers operating costs.

[0011] Furthermore, a plurality of first fixing plates are fixedly connected to the lower surface of the first base, and the first fixing plates are provided with first fixing holes. The first fixing plates and the second fixing plates are arranged on the same horizontal plane.

[0012] The above technical solution can fix the first base to the ground, so that when the hydraulic rod lifts the second base, it can form a lever with the first and second connecting rods to lift the third base. The lifting height is twice that of the second base, so that the photovoltaic panels will not block or interfere with each other.

[0013] Furthermore, the drive mechanism includes a motor fixedly connected to a first base, a second base, and a third base, respectively. A drive gear is fixedly connected to the output end of the motor. A sleeve is fitted on the fixed rod. Driven gears are fixedly connected to both ends of the sleeve. A steel wire rope is wound on the sleeve. Both ends of the steel wire rope are fixedly connected to the mounting base. The drive gear and the driven gear mesh with each other.

[0014] The above technical solution uses a motor to drive a drive gear, which in turn drives a driven gear, which in turn drives a sleeve. The sleeve then drives the mounting base to rotate via a wire rope. This allows the photovoltaic panel to be adjusted to face the sun at any time, improving photovoltaic thermal efficiency. Compared to directly driving the fixed rod to rotate, this method significantly reduces the torque on the fixed rod and extends its service life.

[0015] Furthermore, the lifting mechanism includes a first fixed shaft fixedly connected to both sides of the first base, the second base, and the third base, and a second fixed shaft fixedly connected to both sides of the first base, the second base, and the third base.

[0016] The above technical solution allows the first base, second base, and third base to be connected into a parallelogram mechanism via the first and second connecting rods. This ensures that the third base rises to twice the height of the second base, and also keeps the second and third bases vertical during ascent, preventing the photovoltaic panels from tilting.

[0017] Furthermore, a first connecting rod is rotatably connected through the first fixed shaft, and a second connecting rod is rotatably connected through the second fixed shaft, with the second connecting rod and the first connecting rod arranged in parallel.

[0018] The above technical solution uses a hydraulic rod to push the second base upward. The first, second, and third bases form a parallelogram mechanism through the first and second connecting rods, which causes the third base to rise synchronously. This staggers the photovoltaic panels, preventing them from shading each other and reducing the overall footprint. It also shortens the length required for heat pipe connections, greatly reducing the cost of use.

[0019] Furthermore, the first base, the second base, and the third base are arranged in parallel, and the first base, the second base, and the third base are arranged in a T-shape.

[0020] By using the above technical solution, the parallel arrangement of the first, second, and third bases ensures that the second and third bases remain vertically upright during the upward movement, preventing the photovoltaic panels from tilting due to random rotation.

[0021] The beneficial effects of this invention are as follows: This invention uses a motor to drive a drive gear, which in turn drives a driven gear, which in turn drives a sleeve. The sleeve then drives the mounting base via a wire rope, allowing the photovoltaic panel to be adjusted to face the sun at any time, improving photovoltaic thermal efficiency. Compared to directly driving the fixed rod, this significantly reduces the torque on the fixed rod, extending its service life. Furthermore, this invention uses a hydraulic rod to push the second base upwards. The first, second, and third bases form a parallelogram mechanism with the first and second connecting rods, causing the third base to rise synchronously. This staggers the photovoltaic panels, preventing them from shading each other and reducing the overall footprint. It also shortens the length required for heat pipe connections, greatly reducing operating costs. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] like Figures 1-6 As shown, an adjustable solar photovoltaic-thermal integrated device in this embodiment includes a first base 1, with lifting mechanisms 4 on both sides of the first base 1, and a third base 3 at the end of the lifting mechanism 4 away from the first base 1. A second base 2 is provided between the first base 1 and the third base 3. A support frame 15 is fixedly connected to the upper surface of the first base 1, the second base 2 and the third base 3. A fixed rod 16 is fixedly connected through the support frame 15, and a mounting seat 10 is rotatably connected to the fixed rod 16. The first base 1, the second base 2 and the third base 3 are connected by the lifting mechanism 4, so that the first base 1, the second base 2 and the third base 3 can rise in steps, avoiding mutual shading and interference between the photovoltaic panels 11.

[0026] A number of photovoltaic panels 11 are fixedly connected to the upper surface of the mounting base 10, and a number of brackets 12 are fixedly connected to the mounting base 10. A heat pipe 13 is fixedly connected through the bracket 12. The photovoltaic panel 11 is arranged in a parabolic shape, and the heat pipe 13 is located at the focal point of the parabolic surface of the photovoltaic panel 11. The photovoltaic panel 11 focuses sunlight onto the heat pipe 13, thereby realizing the integration of photovoltaic and photothermal energy.

[0027] A hydraulic rod 9 is rotatably connected to the lower surface of the second base 2. A second fixing plate 7 is fixedly connected to the end of the hydraulic rod 9 away from the second base 2. A number of second fixing holes 8 are provided on the second fixing plate 7. A number of first fixing plates 5 are fixedly connected to the lower surface of the first base 1. A number of first fixing holes 6 are provided on the first fixing plates 5. The first fixing plates 5 and the second fixing plates 7 are set on the same horizontal plane. The first fixing plates 5 and the second fixing plates 7 are fixed to the ground by fixing bolts passing through the first fixing holes 6 and the second fixing holes 8. The second base 2 is raised by the hydraulic rod 9. Then the second base 2 moves the third base 3 upward by the first connecting rod 43 and the second connecting rod 44.

[0028] The lifting mechanism 4 includes a first fixed shaft 41 fixedly connected to both sides of the first base 1, the second base 2, and the third base 3 respectively. A second fixed shaft 42 is fixedly connected to both sides of the first base 1, the second base 2, and the third base 3. A first connecting rod 43 is rotatably connected through the first fixed shaft 41, and a second connecting rod 44 is rotatably connected through the second fixed shaft 42. The second connecting rod 44 and the first connecting rod 43 are arranged in parallel. The first base 1, the second base 2, and the third base 3 are arranged in a T-shape. The heat pipe 13 has connecting interfaces 14 at both ends. Since the first base 1, the second base 2, and the third base 3 are all connected by the first connecting rod 43 and the second connecting rod 44, and the first connecting rod 43 and the second connecting rod 44 are arranged in parallel, the third base 3 remains parallel to the first base 1 during lifting and will not tilt arbitrarily, improving overall stability. This also prevents the photovoltaic panels 11 from obstructing each other, reducing the required floor space and lowering operating costs.

[0029] like Figure 4 and Figure 5 As shown, a drive mechanism is provided on the first base 1, the second base 2, and the third base 3. The drive mechanism includes a motor 17 fixedly connected to the first base 1, the second base 2, and the third base 3, respectively. A drive gear 18 is fixedly connected to the output end of the motor 17. A sleeve 19 is sleeved on the fixed rod 16. Driven gears 20 are fixedly connected to both ends of the sleeve 19. A steel wire rope 21 is wound on the sleeve 19. Both ends of the steel wire rope 21 are fixedly connected to the mounting base 10. The drive gear 18 and the driven gear 20 mesh with each other. The motor 17 drives the drive gear 18 to rotate. The drive gear 18 drives the driven gear 20 to rotate. The driven gear 20 drives the sleeve 19 to rotate around the fixed rod 16. The sleeve 19 drives the mounting base 10 to rotate through the steel wire rope 21, so that the photovoltaic panel 11 faces the sun and focuses the sunlight onto the heat pipe 13. The liquid in the heat pipe 13 is transported to other places through the pipe connection interface 14.

[0030] The working principle of this embodiment is as follows: the first fixing plate 5 and the second fixing plate 7 are fixed to the ground by fixing bolts passing through the first fixing hole 6 and the second fixing hole 8. Then, the motor 17 drives the drive gear 18 to rotate, the drive gear 18 drives the driven gear 20 to rotate, the driven gear 20 drives the sleeve 19 to rotate around the fixing rod 16, and the sleeve 19 drives the mounting base 10 to rotate through the steel wire rope 21, so that the photovoltaic panel 11 faces the sun and focuses the sunlight on the heat pipe 13. The liquid in the heat pipe 13 is transported to other places through the pipe connection interface 14.

[0031] When there is shading between photovoltaic panels 11, the hydraulic rod 9 is activated, which lifts the second base 2. Then, the second base 2 lifts the third base 3 via the first connecting rod 43 and the second connecting rod 44. Since the first base 1, the second base 2, and the third base 3 are all connected by the first connecting rod 43 and the second connecting rod 44, and the first connecting rod 43 and the second connecting rod 44 are set in parallel, the third base 3 is parallel to the first base 1 during the lifting process and will not tilt arbitrarily, which improves the overall stability. At the same time, it prevents the photovoltaic panels 11 from shading each other, reduces the required floor space, and lowers the operating cost.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
