Description

Technical Field

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. The photovoltaic power generation process does not produce greenhouse gas emissions and is environmentally friendly. The photovoltaic power generation system operates stably and reliably, has relatively low maintenance costs, and has a long service life. It can be achieved from small household solar power stations to large centralized solar power plants.

[0003] Photovoltaic brackets are structural devices used to support solar panels in photovoltaic power generation systems. They are important components to ensure the stability of photovoltaic power generation.

[0016] Compared with the prior art, the present invention provides an efficient photovoltaic power generation bracket structure, which has the following

[0017] beneficial effects:

[0018] 1. By setting a translation component and an L-shaped support frame, when the vehicle stops moving and photovoltaic power generation is required, the translation component moves the sliding frame outward. After the sliding frame moves to the outermost end, the opening and closing drive component on its side drives the lowermost L-shaped support frame to rotate. When the lowermost L-shaped support frame rotates 90 degrees, the active baffle on its upper part will fit with the passive baffle under the upper-layer L-shaped support frame and drive it to rotate. And so on. After the lowermost L-shaped support frame rotates 270 degrees, the second-layer L-shaped support frame rotates 180 degrees, and the third L-shaped support frame rotates 90 degrees. At this time, the four L-shaped support frames are completely rotated and unfolded, increasing the area of the photovoltaic panel by four times, achieving the purpose of increasing the area of the photovoltaic panel within a limited range and thus improving the power generation efficiency.

[0019] 2. By setting a first translation component and a second translation component, the first translation component and the second translation component can drive the sliding frames connected to them to move horizontally. When it is necessary to unfold the photovoltaic power generation panel, the first translation component and the second translation component move the folded L-shaped support frame outward through the sliding frame, so as not to affect the unfolding of the L-shaped support frame. On the contrary, when power generation work is not required, the first translation component and the second translation component move the folded L-shaped support frame closer to the center through the sliding component, and the photovoltaic panel carried by it will not exceed the original roof range.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-7 , a high-efficiency photovoltaic power generation bracket structure, including a translation component 1. There are four slide carriages 4 on the translation component 1. There are four L-shaped support frames 2 on the four slide carriages 4. The four L-shaped support frames 2 are stacked on the slide carriage 4. The top L-shaped support frame 2 is fixedly connected to the slide carriage 4. The bottom three L-shaped support frames 2 are sleeved on the slide carriage 4 and rotatably connected thereto. And torsion springs 7 connected to the slide carriage 4 are provided on the middle two L-shaped support frames 2. An active baffle 5 is fixedly provided on the upper parts of the three L-shaped support frames 2 from bottom to top. A passive baffle 6 is fixedly provided on the lower parts of the three L-shaped support frames 2 from top to bottom. And the rotation paths of the active baffle 5 and the passive baffle 6 are the same and the included angle between them is 90 degrees. An opening and closing drive component 3 is provided on the slide carriage 4. The opening and closing drive component 3 is in transmission connection with the lowermost L-shaped support frame 2;

[0030] By setting the translation component 1 and the L-shaped support frame 2, when the vehicle stops moving and photovoltaic power generation is required, the translation component 1 moves the sliding frame 4 outward. When the sliding frame 4 moves to the outermost end, the opening and closing drive component 3 on its side drives the lowermost L-shaped support frame 2 to rotate. When the lowermost L-shaped support frame 2 rotates 90 degrees, the active baffle 5 on its upper part will fit with the passive baffle 6 under the upper-layer L-shaped support frame 2 and drive it to rotate. And so on. When the lowermost L-shaped support frame 2 rotates 270 degrees, the second-layer L-shaped support frame 2 rotates 180 degrees, and the third L-shaped support frame 2 rotates 90 degrees. At this time, the four L-shaped support frames 2 are completely rotated and unfolded, increasing the photovoltaic panel area by four times, achieving the purpose of increasing the photovoltaic panel area within a limited range and thus improving the power generation efficiency;

[0031] In addition, a torsion spring 7 is further provided on the sliding frame 4. The torsion spring 7 is connected to the two middle-layer L-shaped support frames 2. When the lowermost L-shaped support frame 2 is driven by the opening and closing drive component 3 to reset, the two middle-layer L-shaped support frames 2 will rotate and reset relying on the elastic force of the torsion spring 7. In this way, only one L-shaped support frame 2 needs to be driven to complete the unfolding and storage of the remaining L-shaped support frames 2, greatly simplifying the drive structure and reducing the manufacturing and maintenance costs.

[0032] The opening and closing drive component 3 includes a first gear 301 provided under the lowermost L-shaped support frame 2. A second gear 302 is meshed on the side of the first gear 301. A third worm gear 303 is provided under the second gear 302. A third worm 304 is meshed on the side of the third worm gear 303. A second motor 305 is provided on the end face of the third worm 304;

[0033] By setting the third worm 304 and the third worm gear 303, the second motor 305 can drive the third worm 304 to rotate, and drive the second gear 302 to rotate by using the meshing of the third worm 304 and the third worm gear 303, so that the second gear 302 drives the lowermost L-shaped support frame 2 to rotate through the meshing with the first gear 301. And the third worm 304 and the third worm gear 303 have a self-locking characteristic, so that after the second motor 305 stops driving, the self-locking of the third worm 304 and the third worm gear 303 is used to resist the torsion force of the torsion spring 7, so that the L-shaped support frame 2 can be stably fixed for a long time after unfolding.

[0034] The translation component 1 includes a first translation assembly 101 and a second translation assembly 102 arranged vertically and staggeredly. Both the first translation assembly 101 and the second translation assembly 102 are connected to two diagonally opposite sliding frames 4. A translation drive assembly 103 is provided at the staggered position of the first translation assembly 101 and the first translation assembly 101;

[0035] By setting the first translation component 101 and the second translation component 102, the first translation component 101 and the second translation component 102 can drive the sliding frames 4 connected thereto to move horizontally. When the photovoltaic power generation panels need to be unfolded, the first translation member 1 and the second translation member 1 move the folded L-shaped support frame 2 outward through the sliding frames 4, so that the unfolding of the L-shaped support frame 2 will not be affected. On the contrary, when power generation work is not required, the first translation member 1 and the second translation member 1 move the folded L-shaped support frame 2 towards the center through the sliding members, and the photovoltaic panels carried by it will not exceed the original roof range.

[0036] The first translation component 101 includes two first fixing plates 1011. A first bidirectional lead screw 1012 that is in threaded cooperation with the sliding frame 4 is rotatably provided inside the two first fixing plates 1011. A first sliding rod 1014 that is in sliding cooperation with the sliding frame 4 is fixedly provided. The second translation component 102 includes two second fixing plates 1021. A second bidirectional lead screw 1022 that is in threaded cooperation with the sliding frame 4 is rotatably provided inside the two second fixing plates 1021. A second sliding rod 1024 that is in sliding cooperation with the sliding frame 4 is fixedly provided.

[0037] By setting the first bidirectional lead screw 1012 and the second bidirectional lead screw 1022, when the first bidirectional lead screw 1012 and the second bidirectional lead screw 1022 rotate, they drive the horizontal movement thereof by using the threaded cooperation with the sliding frame 4, and the thread directions at both ends are opposite, so that when the two sliding frames 4 connected thereto move, they will move away from or towards each other, achieving the effect of unfolding or storing. In addition, a first sliding rod 1014 and a second sliding rod 1024 are also provided in cooperation. The two can limit the running path of the sliding frame 4 and prevent the sliding frame 4 from rotating on its own.

[0038] The first bidirectional lead screw 1012 and the second bidirectional lead screw 1022 are arranged in a staggered layer. A first support plate 1013 fixedly connected to the first sliding rod 1014 is sleeved near the center position of the first bidirectional lead screw 1012. A second support plate 1023 fixedly connected to the second sliding rod 1024 is sleeved near the center position of the second bidirectional lead screw 1022.

[0039] By setting the first support plate 1013 and the second support plate 1023, the first support plate 1013 is sleeved on the first bidirectional lead screw 1012, and it can support the first bidirectional lead screw 1012 without affecting its rotation, avoiding the problem of jumping caused by the excessive length of the first bidirectional lead screw 1012. The second support plate 1023 has the same effect as above, and is used to support and stabilize the second bidirectional lead screw 1022. In addition, it should be further explained that the first bidirectional lead screw 1012 and the second bidirectional lead screw 1022 are arranged in a staggered layer, so that the two can be linked by the same set of translation drive component 103 to ensure the consistency of the opening and closing and storing work.

[0040] The translation drive assembly 103 includes a connecting frame 1031. A gear set 1032 is provided inside the connecting frame 1031. A first motor 1033 is provided below the gear set 1032. A first worm 1034 and a second worm 1037 are provided above the gear set 1032. A first worm gear 1036 engaged with the side of the first worm 1034 is connected to the first bidirectional lead screw 1012. A second worm gear 1035 engaged with the side of the second worm 1037 is connected to the second bidirectional lead screw 1022.

[0041] By providing the first worm 1034 and the second worm 1037, both the first worm 1034 and the second worm 1037 are provided on the gear set 1032, and the two can rotate synchronously under the drive of the first motor 1033. When the first worm 1034 rotates, it will drive the first bidirectional lead screw 1012 to rotate by using the first worm gear 1036 engaged therewith. When the second worm 1037 rotates, it can drive the second bidirectional lead screw 1022 to rotate through the second worm gear 1035 engaged therewith, achieving the purpose of synchronous rotation of the first bidirectional lead screw 1012 and the second bidirectional lead screw 1022. And by using the transmission characteristics of the worm gear and the worm, it also has the effects of self-locking and speed reduction.

[0042] The L-shaped support frame 2 includes a strengthening member 201 connected to the sliding frame 4. A bearing member 202 for supporting the photovoltaic panel is provided on the side of the strengthening member 201. Mounting holes 203 for fixing the photovoltaic panel are provided inside the bearing member 202.

[0043] By providing the strengthening member 201 and the bearing member 202, the bearing member 202 is L-shaped and can be connected to both sides of the photovoltaic panel by using the mounting holes 203 inside itself. By fixing both sides of the photovoltaic panel, it can support the photovoltaic panel, while the strengthening member 201 can improve the strength of the bearing member 202 and reduce the falling angle of the bearing member 202, so that the photovoltaic panel can be stably placed.

[0044] Working principle: When high-efficiency power generation is required, the translation component 1 drives the sliding frame 4 to move outwards. The sliding frame 4 moves the connected L-shaped support frame 2 to the edge. Then the opening and closing drive component 3 drives the lowermost L-shaped support frame 2 to rotate. When the lowermost L-shaped support frame 2 rotates 90 degrees, the active baffle 5 on its upper part will fit with the passive baffle 6 on the lower part of the upper L-shaped support frame 2. At this time, it will drive the upper L-shaped support frame 2 to rotate. When the lowermost L-shaped support frame 2 rotates 270 degrees, the upper L-shaped support frame 2 will rotate 180 degrees and 90 degrees, so that the stacked lower L-shaped support frame 2 and the photovoltaic panel carried by it are unfolded.

[0045] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
