Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic assembly installation, and in particular to a photovoltaic assembly installation structure that is easy to flip. Background Art

[0002] A photovoltaic power generation device is a power generation device that uses photovoltaic modules to absorb solar radiation energy and convert it into electrical energy. However, the angle of light varies throughout the year, and fixed photovoltaic modules cannot keep their light-receiving surfaces perpendicular to the sunlight. Therefore, they cannot maximize the absorption of solar radiation and achieve optimal power generation efficiency. Photovoltaic brackets that can adjust the angle position of photovoltaic modules can drive photovoltaic modules to dynamically change the installation angle, allowing photovoltaic modules to track the position of the sun as much as possible so that their light-receiving surfaces are perpendicular to the sunlight. For example, patent No. 2022212287144 discloses an angle-adjustable photovoltaic bracket.

[0003] For photovoltaic modules installed on the plateau, due to environmental and weather reasons, when encountering strong winds, the inclined photovoltaic panels are easily blown over due to the large contact area with the strong wind. In addition, strong winds can easily blow up flying sand and hit the photovoltaic panels, causing the photovoltaic panels to be scratched, which greatly affects the efficiency of the photovoltaic panels in absorbing sunlight. In addition, hail is very likely to occur on the plateau. If hail falls directly on the photovoltaic panels, the photovoltaic panels are easily damaged. For this reason, a photovoltaic module installation structure that is easy to flip is proposed. Summary of the Invention

[0015] 2. During the flipping process of the photovoltaic panel, the multiple blades on the shielding mechanism can be flipped synchronously to ensure that the edges of the blades can remain perpendicular to the sunlight and that the sunlight blocked by the blades can be ignored;

[0016] 3. When the photovoltaic panel is in a horizontal state and a maximum tilt state, the shielding mechanism is in a completely closed state, thereby ensuring that the shielding mechanism can completely shield the photovoltaic panel. Therefore, in windy weather, shielding the photovoltaic panel through the shielding mechanism can prevent sand and gravel in the wind from contacting the photovoltaic panel, and can avoid the photovoltaic panel being scratched by sand and gravel. In hail weather, the shielding mechanism in the maximum tilt state has a smaller contact area with the hail. In addition, since multiple blades are in an inclined state, the shielding mechanism can weaken the impact force generated by the hail, and provide certain protection for itself and the photovoltaic panel.

[0027] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please refer to Figures 1-9 The present invention provides a technical solution: a photovoltaic assembly installation structure that is easy to flip, comprising two bases 1, both of which are fixedly mounted with a connecting seat 2, a support rod 3 and a telescopic mechanism 4 are provided above the base 1, the bottoms of the support rod 3 and the telescopic mechanism 4 are fixedly connected to the corresponding connecting seat 2 respectively, the tops of the two support rods 3 and the two telescopic mechanisms 4 are hinged with the same photovoltaic bracket 6, the top of the photovoltaic bracket 6 is fixedly mounted with a photovoltaic panel 5, the same adjustment mechanism 7 is provided between the two telescopic mechanisms 4, the adjustment mechanism 7 is used to detect the wind force and drive the two telescopic mechanisms 4 to extend and retract, the extension and retraction of the two telescopic mechanisms 4 will drive the photovoltaic panel 5 to flip at different angles with the connection point between the photovoltaic bracket 6 and the support rod 3 as the center of the circle, a protective mechanism 9 is fixedly mounted on the top of the photovoltaic panel 5, and a shielding mechanism 8 is provided on the protective mechanism 9. During the flipping process of the photovoltaic panel 5, the shielding mechanism 8 will present different opening angles.

[0029] The telescopic mechanism 4 includes a circular box 41 whose bottom end is fixedly connected to the corresponding connecting seat 2, a cylinder 42 is slidably installed on the circular box 41, a connecting block 47 is fixedly installed on the top of the cylinder 42, and the connecting block 47 is connected to the photovoltaic bracket 6, a slider 43 is fixedly installed on the bottom end of the cylinder 42, and the slider 43 is slidably connected to the inner wall of the circular box 41, and a bevel gear 45 is rotatably installed on the bottom inner wall of the circular box 41, and a screw 44 is fixedly installed on the top of the bevel gear 45, which is threadedly connected to the inner wall of the cylinder 42, and a bevel gear 2 46 is meshed with the bevel gear 1 45.

[0030] The bottom of the photovoltaic bracket 6 is provided with two rotating shafts 61 and two rotating shafts 62. The two rotating shafts 61 and the two rotating shafts 62 are arranged in a rectangular shape. The two rotating shafts 61 respectively pass through the corresponding rotating shaft 61 and are rotatably connected to the corresponding rotating shaft 61. A sliding hole 48 is provided on the connecting block 47. The two rotating shafts 62 respectively pass through the corresponding sliding hole 48 and are rollingly connected to the inner wall of the corresponding sliding hole 48.

[0031] Furthermore, when the photovoltaic panel 5 rotates with the axes of the two first rotating shafts 61 as the center, the second rotating shaft 62 slides in the sliding hole 48 .

[0032] Two symmetrically distributed guide grooves are provided on the side of the slider 43. Two guide rods are fixedly installed on the inner wall of the round box 41. The two guide rods are slidingly connected to the inner walls of the corresponding guide grooves. A limit ring 49 is fixedly installed on the inner wall of the round box 41. The limit ring 49 is located above the bevel gear 2 46.

[0033] Furthermore, through the cooperation of the guide groove and the guide rod, the slider 43 can only move vertically up and down in the round box 41, ensuring that when the screw 44 rotates, the cylinder 42 can only move up and down, and by setting a limit ring 49, the downward movement of the slider 43 can be limited to ensure that the slider 43 will not contact the bevel gear 2 46.

[0034] The adjusting mechanism 7 includes an installation box 71, and circular tubes 72 are fixedly installed on both sides of the installation box 71. The ends of the two circular tubes 72 away from each other are fixedly connected to the corresponding circular boxes 41. The two circular boxes 41 are connected to the installation box 71 through the corresponding circular tubes 72. A plurality of support rings 75 are fixedly installed in the circular tube 72. The same transmission shaft 76 is rotatably installed in the plurality of support rings 75. The ends of the two transmission shafts 76 away from each other are fixedly connected to the corresponding bevel gears 46. A dual-axis motor 74 is fixedly installed in the installation box 71, and the two ends of the output shaft of the dual-axis motor 74 are fixedly connected to the corresponding transmission shafts 76.

[0035] Furthermore, by controlling the rotation direction of the dual-axis motor 74 , the telescopic mechanism 4 can be extended or retracted.

[0036] A wind speed meter 73 is fixedly installed on the outside of the installation box 71.

[0037] Furthermore, the wind speed meter 73 can detect the strength of the wind blowing directly on the front or back of the photovoltaic panel 5 .

[0038] The protection mechanism 9 includes two baffles 1 91 and two baffles 2 92 . The two baffles 2 92 are located between the two baffles 1 91 and are fixedly connected to the two baffles 1 91 . An ash discharge pipe 93 is fixedly installed through the baffle 1 91 near the two support rods 3 .

[0039] Furthermore, when the photovoltaic panel 5 is in an inclined state, the baffle 91 equipped with the ash discharge pipe 93 is in a lower state. At this time, the dirt that falls on the top of the photovoltaic panel 5 and is not stuck will automatically roll along the inclined photovoltaic panel 5 to the ash discharge pipe 93 and finally be discharged from the ash discharge pipe 93.

[0040] The shielding mechanism 8 includes two horizontal plates 81 fixedly mounted on the top of the two baffles 92, and a plurality of linearly distributed baffles 82 are provided between the two baffles 91. A circular shaft 83 is fixedly mounted at both ends of the baffle 82. The circular shafts 83 at both ends of the baffle 82 respectively rotate through the corresponding horizontal plates 81. A swing arm 84 is fixedly sleeved on the circular shaft 83. The same horizontal plate 85 is hinged on the multiple swing arms 84 on the same side. Two rollers 86 are rotatably mounted on the side of the horizontal plate 85 away from the swing arm 84. The same vertical rod 87 is provided between the two rollers 86, and the bottom end of the vertical rod 87 is fixedly connected to the corresponding base 1.

[0041] In this embodiment: when in use, when it is necessary to adjust the inclination angle of the photovoltaic panel 5, it is only necessary to start the installation box 1 71, and the installation box 1 71 drives the two transmission shafts 76 to rotate, and the transmission shaft 76 then drives the bevel gear 1 45 to rotate through the bevel gear 2 46, and the rotation of the bevel gear 1 45 will drive the screw 44 to rotate. During the rotation of the screw 44, the cylinder 42 will move up and down along the axial direction, and the cylinder 42 will drive the connecting block 47 to move up and down. When the connecting block 47 moves up and down, it will drive the photovoltaic bracket 6 and the two rotating shafts 1 61 to rotate as the center of the circle. The photovoltaic bracket 6 drives the photovoltaic panel 5 to rotate synchronously, so that the photovoltaic panel 5 presents different inclination angles;

[0042] When the photovoltaic panel 5 rotates with the two rotating shafts 61 as the center, the positions of the four rollers 86 on the two horizontal plates 85 thereon will change. However, due to the obstruction of the two vertical rods 87, the front and rear positions of the two horizontal plates 85 will be displaced. The horizontal plates 85 then drive the multiple baffles 82 to flip through the multiple swing arms 84, thereby ensuring that when the inclination angle of the photovoltaic panel 5 is adjusted, the inclination angles of the multiple baffles 82 will also change simultaneously, ultimately ensuring that the sun's radiation angle is always perpendicular to the edges of the baffles 82. Since the edges of the baffles 82 block very little sunlight, it is ensured that sunlight can fully illuminate the photovoltaic panel 5.

[0043] When the wind speed meter 73 detects the occurrence of strong winds, the dual-axis motor 74 can be remotely started to fully retract the two telescopic mechanisms 4. During this process, the two telescopic mechanisms 4 will drive the photovoltaic panels 5 to rotate around the rotating shaft 1 61 and be in a horizontal state. The photovoltaic panels 5 in the horizontal state have a smaller windward surface, so when encountering strong winds, the photovoltaic panels 5 can be prevented from being overturned by the strong wind. In the case of hail, the dual-axis motor 74 is remotely started to fully extend the two telescopic mechanisms 4, so that the photovoltaic panels 5 are in a maximum tilt state.

[0044] When the photovoltaic panel 5 is in a horizontal state and a maximum tilt state, the ends of the multiple blades 82 will fit together, so as to completely cover the photovoltaic panel 5. Therefore, in windy weather, the shielding mechanism 8 shields the photovoltaic panel 5, which can prevent sand and gravel in the wind from contacting the photovoltaic panel 5, and can avoid the photovoltaic panel 5 being scratched by sand and gravel. In hail weather, the shielding mechanism 8 in the maximum tilt state has a smaller contact area with the hail. In addition, since the multiple blades 82 are in a tilted state, the shielding mechanism 8 can weaken the impact force generated by the hail, and provide certain protection for itself and the photovoltaic panel 5.

[0045] 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.
