Description

Technical Field

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

[0002] A photovoltaic power generation device is a device that converts solar energy into electrical energy. Its principle is to generate current by shining sunlight on photovoltaic cells, thereby realizing the conversion of electrical energy.

[0003] For example, the Chinese patent publication number is CN115833722A, and the technical solution disclosed in the patent document is as follows: a retractable photovoltaic panel with an auxiliary support structure, comprising a base support frame mounted on a rooftop by fastening bolts, wherein the upper end of the base support frame is rotatably mounted with a base bottom plate; further comprising: a half-toothed ring fixedly mounted below the photovoltaic panel assembly; a reinforcing support rod obliquely mounted between the base support frame and the mounting plate; and a movable plate disposed between two groups of photovoltaic panel assemblies. The retractable photovoltaic panel with an auxiliary support structure, through a fixed rod sleeved inside the base bottom plate, enables the fixed rod to rotate the two half-toothed rings by means of a driving gear when the base bottom plate rotates on the base support frame, thereby driving the two mounting plates to rotate relative to each other, thereby achieving retraction and folding, reducing the wind-exposed area, making it less susceptible to damage in windy weather, and facilitating the cleaning of impurities on the surface of the photovoltaic panel assembly.

[0004] The existing technology has the following problems: The above-mentioned device performs the process of adjusting and folding the photovoltaic panel simultaneously, so the range of its tilt angle adjustment is relatively small; secondly, the photovoltaic panel is folded downward from the middle, and its surface is still exposed. Although the wind-exposed area is reduced, it cannot achieve a protective effect in the face of extreme weather such as hail. Summary of the Invention

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] For example 1, please refer to Figure 1-Figure 3The present embodiment provides a retractable photovoltaic power generation device, comprising a bottom plate 1, a support plate 2 being fixedly connected to the upper end of the bottom plate 1, a photovoltaic panel 3 being arranged between the support plates 2, a rotating rod 41 being rotatably connected between the support plates 2, a connecting block A42 being fixedly sleeved on the outer wall of the rotating rod 41, a protective frame 43 being hingedly connected to the outer wall of the connecting block A42, an electric telescopic rod 44 being fixedly connected to the outer wall of the support plate 2, a connecting block B45 being fixedly connected to the output end of the electric telescopic rod 44, an arc frame 46 being fixedly connected to the outer wall of the connecting block B45, and the arc frame The inner wall of 46 is rotatably connected to a connecting shaft 47, and the outer wall of connecting shaft 47 is rotatably connected to a connecting block C48. The outer wall of connecting block C48 is fixedly connected to the photovoltaic panel 3. The other end of the photovoltaic panel 3 is rotatably connected to the interior of the protective frame 43 via a pin. The outer wall of the protective frame 43 is fixedly connected to a hydraulic chamber A49. The two ends of the hydraulic chamber A49 are internally slidably connected to hydraulic rods A410 and B411. The other end of hydraulic rod B411 is fixedly connected to a baffle 412. Baffle 412 is moved by the hydraulic system to provide protection for the upper end. When the photovoltaic panel 3 is folded, baffle 412 will move to a larger position, protecting the upper end of the equipment from external damage. The upper end of connecting shaft 47 is equipped with a cleaning assembly 5, and the interior of baffle 412 is provided with a diversion assembly 6. The outer wall of support plate 2 is fixedly connected to a motor 413, and the output end of motor 413 is fixedly connected to rotating rod 41. A slot 414 is formed on the outer wall of one side support plate 2, into which a connecting block B45 is slidably connected. The slot 414 allows the connecting block B45 to slide, ensuring smooth movement of the electric telescopic rod 44. A through slot is formed on the outer wall of the protective frame 43, into which a baffle 412 is slidably connected.

[0026] When in use, first, when the photovoltaic panel 3 needs to be adjusted to adapt to the angle of sunlight, the motor 413 is started to drive the rotating rod 41 to rotate, and then the connecting block C48 outside the rotating rod 41 will also rotate accordingly, and then the protective frame 43 outside the connecting block C48 will rotate accordingly, and then the photovoltaic panel 3 inside the protective frame 43 will also rotate accordingly, and the connecting shaft 47 that is rotatably connected to the other end of the photovoltaic panel 3 through the connecting block C48 will slide in the arc groove inside the arc frame 46, thereby realizing the inclination adjustment of the photovoltaic panel 3. When the photovoltaic panel 3 needs to be folded for protection, the photovoltaic panel 3 can be reset to a state parallel to the bottom plate 1 first, and then the electric telescopic rod 44 is started to drive the connecting block B45 to slide to the lower end inside the slide groove 414. Then the connecting block B45 will drive the arc frame 46 to move toward the lower end, and the connecting shaft 47 located inside it will also move toward the lower end, and then it will drive one end of the photovoltaic panel 3 to move toward the lower end through the connecting block C48 outside it. Since the other end of the photovoltaic panel 3 is hinged to the inside of the protective frame 43, when the photovoltaic panel 3 rotates and folds inward, it will drive the protective frame 43 to fold inward as well, and then the distance between the photovoltaic panel 3 and the inner wall of the protective frame 43 will become closer and closer, and then the photovoltaic panel 3 will squeeze the hydraulic rod A410 to move toward the inside of the hydraulic warehouse A49, and then the hydraulic rod B411 located inside the other end of the hydraulic warehouse A49 will slide outward, thereby driving the baffle 412 to slide toward the middle, thereby expanding the protection area of the upper end.

[0027] For example 2, please refer to Figure 1-Figure 5 , cleaning component 5, the cleaning component 5 includes a negative pressure airbag 51, the negative pressure airbag 51 is fixedly connected to the upper end of the connecting shaft 47, the negative pressure airbag 51 is located at the upper end of the connecting shaft 47, and its function is to generate negative pressure, inhale air or gas, so that the gas flows and drives the movement of other components, the two ends of the negative pressure airbag 51 are rotatably connected to a connecting pipe 52 through a rotating joint, the outer wall of the connecting pipe 52 is provided with a magnetic block 53, the outer wall of the connecting pipe 52 is movably sleeved with a magnetic ring 54, and the outer wall of the magnetic ring 54 is fixedly connected with a scraper 55.

[0028] The magnetic block 53 is magnetically connected to the magnetic ring 54, and the bottom of the scraper 55 is in close contact with the surface of the photovoltaic panel 3. The scraper 55 slides across the surface of the photovoltaic panel 3 to remove dust, dirt, snow, etc., ensuring the surface of the photovoltaic panel 3 is clean, thereby improving the power generation efficiency of the photovoltaic panel 3. The magnetic connection ensures that the scraper 55 can smoothly clean along the surface of the photovoltaic panel 3. The connection between the magnetic block 53 and the magnetic ring 54 ensures that the scraper 55 moves freely during the cleaning process and does not deviate from its track.

[0029] During use, when the photovoltaic panels 3 on both sides are folded inward, when the angle at the bottom of the photovoltaic panels 3 becomes smaller and smaller, the negative pressure airbag 51 located at the upper end of the connecting shaft 47 will be squeezed, and the gas inside it will enter the interior of the connecting tube 52, which will cause the magnetic block 53 inside the connecting tube 52 to slide, and the magnetic ring 54 magnetically connected to it will slide from one side to the other on the outer wall of the connecting tube 52, and can drive the scraper 55 to move from one side of the photovoltaic panel 3 to the other side, thereby achieving the cleaning of the surface of the photovoltaic panel 3.

[0030] For example three, please refer to Figure 1-Figure 7 The guide assembly 6 includes a accommodating groove 61, which is opened inside the baffle 412. The inside of the accommodating groove 61 is slidably connected to a slide plate 62, and the inner side of the slide plate 62 is rotatably connected to a mounting shaft 63. The outer wall of the mounting shaft 63 is fixedly sleeved with a guide plate 64. The outer wall of the baffle 412 is fixedly connected to a hydraulic bin B65, and the two ends of the hydraulic bin B65 are slidably connected to a hydraulic rod C66 and a hydraulic rod D67. The other end of the hydraulic rod C66 is fixedly connected to the slide plate 62, and the top of the support plate 2 is fixedly connected to a fixed plate 68. A torsion spring 69 is fixedly connected between the slide plate 62 and the guide plate 64.

[0031] A connecting ring 611 is fixedly connected to the outer wall of hydraulic rod D67. A spring 610 is fixedly connected to the outer wall of connecting ring 611. The other end of spring 610 is fixedly connected to the outer wall of hydraulic chamber B65. Spring 610 and connecting ring 611 ensure that hydraulic rod D67 and hydraulic rod C66 rebound and return to their original positions after deflector 64 moves. The reaction force of spring 610 ensures that deflector 64 automatically returns to its original position when no external force is applied, preventing deflector 64 from remaining deployed in the absence of external forces.

[0032] When in use, when the baffle 412 moves outward, it will drive the hydraulic bin B65 to move at the same time, and before the protective frame 43 is folded to the minimum angle, the hydraulic rod D67 at one end of the hydraulic bin B65 will contact the fixed plate 68 at the upper end of the support plate 2, and then the hydraulic rod C66 at the other end of the hydraulic bin B65 will move outward, and then push the slide 62 to slide inside the receiving groove 61, then the guide plate 64 connected to the front end of the slide 62 by the mounting shaft 63 will also move to the outside of the baffle 412. When the guide plate 64 and the mounting shaft 63 move to the outside of the baffle 412, since the guide plate 64 loses the restriction of the receiving groove 61, the torsion spring 69 The lower guide plate 64 rotates upward, and can then fit together with the guide plate 64 on the other side to form a triangular structure, thereby preventing water from accumulating at the upper end of the baffle 412, and preventing hail from accumulating at the upper end of the photovoltaic panel 3 when hail occurs, thereby avoiding damage to the photovoltaic panel 3 when it is unfolded. When the protective frame 43 is reset, the hydraulic rod D67 will be pushed outward through the connecting ring 611 under the action of the spring 610, thereby driving the hydraulic rod C66 to reset, and then the slide plate 62 will slide toward the inside of the receiving groove 61, and then after the guide plate 64 contacts the notch of the receiving groove 61, it will gradually tend to a balanced state until it completely returns to the inside of the receiving groove 61.

[0033] 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 the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
