[0002] Solar power generation devices refer to a method of generating electricity by directly converting light energy into electrical energy without going through a thermal process. In some buildings, in order to reduce the use of indoor electricity, corresponding solar power generation devices are usually installed on the roof of the building.

[0003] For example, a solar power generation device with publication number CN210469169U includes a mounting column and a solar panel. The solar panel is located on the right side of the mounting column. The interior of the mounting column is a hollow structure. A rotating shaft is provided inside the mounting column. The rotating shaft is rotatably plugged into the axis of the mounting column. The fan-shaped block is located on the right side of the rotating shaft.

[0004] The above-mentioned prior art has the following technical problems: the existing solar power generation device is directly exposed to the outside when in use. When hail and severe weather occur outside, it is not convenient to shield and protect its light absorption area, which can easily cause hail to directly hit the power generation device, causing damage to the power generation device. At the same time, when the power generation device is performing photoelectric conversion, its overall light absorption range is small, thereby reducing its own photoelectric conversion effect.

[0005] Therefore, we propose a solar power generation device to solve the above problems. Utility Model Content

At the same time, when the power generation device performs photoelectric conversion, its overall light absorption range is small, thereby reducing its own photoelectric conversion effect.

[0007] To achieve the above object, the utility model provides the following technical solution: a solar power generation device, comprising a positioning frame, the interior of which is inlaid with a photovoltaic panel, and the positioning frame is fixed to a support frame at the upper end of a building roof;

[0010] The two guide shafts are connected to two rope drums respectively through pull ropes, and the rope drums are fixed on the output end of the servo motor;

[0011] The inner side of the protective plate is inlaid with a reflective lens, and the outer side of the protective plate is connected to each other through a return spring and a buffer plate. A cleaning mechanism is installed between the photovoltaic panel and the protective plate to clean dust on the surface of the photovoltaic panel and the reflective lens.

[0014] Preferably, the winding directions of the pull ropes on the two rope drums at the output end of the servo motor are opposite.

[0015] By adopting the above technical solution, the winding directions of the pull rope are opposite, so that when the two rope drums rotate in the same direction, the two protection plates and the guide shaft can be pulled to open and close synchronously.

[0016] Preferably, the buffer plate and the protective plate are distributed in parallel, and a plurality of return springs are evenly distributed between the buffer plate and the protective plate.

[0025] 1. A protective plate is provided. When hail falls outside, the two rope drums on the output end can be rotated by turning on the servo motor. The rotation of the two rope drums can be used to pull the protective plate and the guide shaft to rotate by pulling the rope. The protective plate is rotated to a position flush with the positioning frame, so that the photovoltaic panel on the positioning frame can be shielded to prevent hail from directly impacting the photovoltaic panel;

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example 1: Please refer to Figure 1-Figure 3 The existing solar power generation device is directly exposed to the outside when in use. When hail and severe weather occur outside, it is not convenient to shield and protect its light absorption area, which easily causes hail to directly hit the power generation device, causing damage to the power generation device. In order to solve this technical problem, the present embodiment discloses the following technical content: a solar power generation device, including a positioning frame 1, a photovoltaic panel 2 is embedded in the interior of the positioning frame 1, and the positioning frame 1 is fixed on the support frame at the upper end of the building roof; the left and right sides of the upper end of the positioning frame 1 are connected to guide shafts 3, and the two guide shafts 3 are fixedly connected to protective plates 4, and the outer side of the end of the guide shaft 3 is installed with a vortex spring 5 providing a reset elastic force; the two guide shafts 3 are respectively connected to the two rope drums 7 through the pull rope 6, and the rope drum 7 is fixed on the output end of the servo motor 8; the protective plate 4 forms a rotating structure with the positioning frame 1 through the guide shaft 3, and the protective plate 4 is symmetrically arranged about the longitudinal center axis of the photovoltaic panel 2. The pull ropes 6 on the two rope drums 7 at the output end of the servo motor 8 are wound in opposite directions.

[0038] The positioning frame 1 is fixed on the bracket on the roof of the building for use. When hail falls outside, the servo motor 8 at the bottom of the positioning frame 1 is turned on. After the servo motor 8 is turned on, the two rope drums 7 on the output end can rotate synchronously. When the rope drums 7 rotate, the pull ropes 6 can be used to pull the two protective plates 4 to rotate until the two protective plates 4 rotate to a position parallel to the positioning frame 1. The two protective plates 4 are rotated and closed to shield the photovoltaic panels 2 on the positioning frame 1 to prevent hail from outside from directly impacting the photovoltaic panels 2.

[0039] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. When the power generation device performs photoelectric conversion, its overall light absorption range is small, thereby reducing its own photoelectric conversion effect. Figure 1 , Figure 3-Figure 5 As shown, this embodiment discloses the following technical contents: a reflective lens 9 is inlaid on the inner side of the protective plate 4, and the outer side of the protective plate 4 is connected to each other through a return spring 11 and a buffer plate 10, the buffer plate 10 and the protective plate 4 are parallelly distributed, and a plurality of return springs 11 are evenly distributed between the buffer plate 10 and the protective plate 4. The surface of the reflective lens 9 and the protective plate 4 are flush with each other, and the reflective lens 9 is set to a rectangular structure.

[0040] When hail falls outside, the hail first contacts the buffer plate 10 on the outside of the protective plate 4. When the buffer plate 10 is subjected to force, its return spring 11 can be elastically deformed. The elastic deformation of the return spring 11 can play a buffering role, thereby preventing unnecessary damage to the device caused by excessive impact force when hail falls. When the sky is clear, the protective plate 4 is rotated and opened to a tilted state under the action of the pull rope 6 and the vortex spring 5, and the surrounding sunlight can be reflected onto the photovoltaic panel 2 through the reflective lens 9 on the inside of the protective plate 4.

[0041] Embodiment 3: The technical content disclosed in this embodiment is a further improvement on the above-mentioned embodiments 1 and 2. When the existing power generation device is in use, a lot of dust and impurities are attached to the surface of the power generation area, which easily leads to poor absorption of external sunlight during the day. In order to solve this technical problem, Figure 1 , Figure 3 and Figure 6As shown, a cleaning mechanism 12 is installed between the photovoltaic panel 2 and the protective plate 4, which is used to clean the dust on the surface of the photovoltaic panel 2 and the reflective lens 9. The cleaning mechanism 12 includes a cylinder 121, and the cylinder 121 is fixed to the front end of the positioning frame 1, and an adjustment plate 122 is fixedly connected to the telescopic end of the cylinder 121, and the upper and lower ends of the adjustment plate 122 are fixedly connected to cleaning cotton cloth 123. The cleaning cotton cloth 123 at the upper end of the adjustment plate 122 and the inner surface of the protective plate 4 are in contact with each other, and the cleaning cotton cloth 123 at the lower end of the adjustment plate 122 and the photovoltaic panel 2 on the positioning frame 1 are in contact with each other.

[0042] At night, the protective plate 4 rotates and closes. At this time, the lower surface of the protective plate 4 fits against the cleaning cotton cloth 123 on the adjusting plate 122. At this time, the cylinder 121 is turned on. After the cylinder 121 is turned on, it can push the adjusting plate 122 to move. After the adjusting plate 122 moves, the cleaning cotton cloth 123 at the upper end can be used to clean the dust on the surface of the reflective lens 9 on the protective plate 4. At the same time, the cleaning cotton cloth 123 at the lower end of the adjusting plate 122 can be used to clean the dust attached to the surface of the photovoltaic panel 2, so as to ensure the cleanliness of the reflective lens 9 and the surface of the photovoltaic panel 2.
