Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic generators, and specifically to an adjusting device for the light-receiving area of a photovoltaic generator set. Background Technique

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. The photovoltaic power generation process is simple, without mechanical rotating parts, does not consume fuel, does not emit any substances including greenhouse gases, is noise-free and pollution-free. Solar energy resources are widely distributed and inexhaustible. Compared with new power generation technologies such as wind power generation, biomass power generation, and nuclear power generation, photovoltaic power generation is a renewable energy power generation technology with the most ideal characteristics of sustainable development and has been more and more widely used.

[0003] In the current practical application of photovoltaic power generation, the position of the solar panels of the photovoltaic generator set is fixed, and they can only receive sunlight from the front area. The light-receiving area is fixed and cannot be adjusted. The light-receiving area of the generator set affects the absorption of light energy by the solar panels, resulting in the fact that the actual converted electrical energy of photovoltaic power generation cannot meet people's electricity consumption needs. Moreover, the solar panels of the photovoltaic generator set are not provided with shielding, and are prone to failure in rainy days. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides an adjusting device for the light-receiving area of a photovoltaic generator set, which has the advantages of automatically adjusting the light-receiving area of the photovoltaic generator set and rain protection.

[0005] To achieve the above object, the present invention provides the following technical solution: An adjusting device for the light-receiving area of a photovoltaic generator set, including a photovoltaic generator set and a support column. A convex mirror is fixedly connected to the top of the support column, and an axle fixator is fixedly connected to the outside of the top of the support column. A driving shaft is rotatably connected to the inside of the axle fixator. A rotating structure is fixedly connected to the outside of the driving shaft. A driving mechanism is fixedly connected to the outside of the axle fixator. A moving mechanism is fixedly connected to the outside of the rotating structure. A convex lens is installed on the top of the moving mechanism.

[0006] Preferably, the driving mechanism includes a motor frame, a motor is fixedly connected to the inside of the motor frame, and a motor rotating shaft is fixedly connected to the output end of the motor.

[0007] Preferably, the moving mechanism includes a telescopic rod, an adapter is fixedly connected to the outside of the telescopic rod, an auxiliary telescopic rod is fixedly connected to the top of the adapter, an auxiliary adapter is fixedly connected to the top of the auxiliary telescopic rod, and a clamp is fixedly connected to the top of the auxiliary adapter.

[0008] Preferably, both sides of the convex lens and the convex mirror are convex, and the focal lengths of both are greater than the distance between the center points of both and the center point of the photovoltaic power generation unit, effectively preventing the convex lens and the convex mirror from concentrating sunlight on a single point on the solar panel of the photovoltaic power generation unit, thus avoiding harm.

[0009] Preferably, there are four sets of the driving mechanism, the moving mechanism and the convex lens, effectively increasing the light-receiving area of the photovoltaic power generation unit.

[0010] Preferably, the motor frame is fixedly connected to the shaft fixator, and the motor rotating shaft is fixedly connected to the driving shaft. The motor rotating shaft can drive the driving shaft to rotate.

[0011] Preferably, the telescopic rod is fixedly connected to the rotating structure, and the fixture is detachably connected to the convex lens. The rotating structure has a supporting and fixing effect on the telescopic rod.

[0012] Beneficial effects:

[0013] 1. For the adjusting device of the light-receiving area of the photovoltaic power generation unit, the position of the convex mirror is fixed by the support column, so that the angle between the convex mirror and the horizontal plane is the same as the angle between the solar panel of the photovoltaic power generation unit and the horizontal plane, and sunlight can be concentrated on the solar panel of the photovoltaic power generation unit. At this time, the motor can be turned on. The motor will drive the motor rotating shaft to rotate. When the motor rotating shaft rotates, the driving shaft fixedly connected to the motor rotating shaft will also start to rotate. The rotation of the driving shaft will drive the rotating structure fixedly connected to the driving shaft to rotate together, thereby adjusting the position of the moving mechanism fixedly connected to the driving shaft, so that the convex lens connected to the moving mechanism can concentrate sunlight on the solar panel of the photovoltaic power generation unit, thus increasing the light-receiving area of the photovoltaic power generation unit and completing the automatic adjustment of the light-receiving area of the photovoltaic power generation unit.

[0014] 2. For the adjusting device of the light-receiving area of the photovoltaic power generation unit, the convex mirror shields the photovoltaic power generation unit. When the adjusting device of the light-receiving area of the photovoltaic power generation unit is in use, the support column is fixed on the outside of the photovoltaic power generation unit. At this time, the convex mirror completely shields the upper part of the photovoltaic power generation unit, providing an effective rain-proof function when it rains and completing rain-proofing.

Specific implementation mode

[0020] 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.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 , an adjusting device for the light-receiving area of a photovoltaic power generation unit, including a photovoltaic power generation unit 1 and a support column 2. A convex mirror 3 is fixedly connected to the top of the support column 2. An outer side of the top of the support column 2 is fixedly connected with a shaft fixator 4. A driving shaft 5 is rotatably connected to the inside of the shaft fixator 4. A rotating structure 6 is fixedly connected to the outside of the driving shaft 5. A driving mechanism 7 is fixedly connected to the outside of the shaft fixator 4. A moving mechanism 8 is fixedly connected to the outside of the rotating structure 6. A convex lens 9 is installed on the top of the moving mechanism 8.

[0023] Among them, the driving mechanism 7 includes a motor frame 71. A motor 72 is fixedly connected to the inside of the motor frame 71. An output end of the motor 72 is fixedly connected with a motor rotating shaft 73.

[0024] Among them, the moving mechanism 8 includes a telescopic rod 81. An adapter 82 is fixedly connected to the outside of the telescopic rod 81. An auxiliary telescopic rod 83 is fixedly connected to the top of the adapter 82. An auxiliary adapter 84 is fixedly connected to the top of the auxiliary telescopic rod 83. A fixture 85 is fixedly connected to the top of the auxiliary adapter 84.

[0025] Among them, both sides of the convex mirror 3 and the convex lens 9 are convex, and the focal lengths of both are greater than the distance between the center point positions of both and the center point position of the photovoltaic power generation unit 1, effectively avoiding the convex lens 9 and the convex mirror 3 from converging sunlight at a point on the solar panel of the photovoltaic power generation unit 1, and uniformly scattering the converged sunlight within the solar energy range of the photovoltaic power generation unit 1, maximizing the utilization of sunlight, reducing energy waste, and at the same time avoiding the harm caused by the sunlight converging at a point to the solar panel of the photovoltaic power generation unit 1.

[0026] Among them, there are four sets of driving mechanisms 7, moving mechanisms 8 and convex lenses 9, which effectively increase the light-receiving area of the photovoltaic power generation unit 1.

[0027] Among them, the motor frame 71 is fixedly connected to the shaft fixator 4, the motor rotating shaft 73 is fixedly connected to the driving shaft 5, and the motor rotating shaft 73 can drive the driving shaft 5 to rotate.

[0028] Among them, the telescopic rod 81 is fixedly connected to the rotating structure 6, the fixture 85 is detachably connected to the convex lens 9, and the rotating structure 6 has a supporting and fixing effect on the telescopic rod 81.

[0029] Working principle: When the adjusting device for the light-receiving area of the photovoltaic power generation unit is in use, the support column 2 fixes the position of the convex lens 3, so that the angle between the convex lens 3 and the horizontal plane is the same as the angle between the solar panel of the photovoltaic power generation unit 1 and the horizontal plane. And the focal length of the convex lens 3 is greater than the distance between the position of its center point and the center point position of the photovoltaic power generation unit 1, so that the convex lens 3 can converge the sunlight on the solar panel of the photovoltaic power generation unit 1, avoiding the harm caused by the sunlight converging at one point to the solar panel of the photovoltaic power generation unit 1. At this time, the motor 72 can be turned on, and the motor 72 will drive the motor rotating shaft 73 to rotate. When the motor rotating shaft 73 rotates, the driving shaft 5 fixedly connected to the motor rotating shaft 73 will also start to rotate. The rotation of the driving shaft 5 will drive the rotating structure 6 fixedly connected to the driving shaft 5 to rotate together, thereby adjusting the position of the telescopic rod 81 of the moving mechanism 8 fixedly connected to the driving shaft 5. And the telescopic rod 81 can extend or contract. During this process, the convex lens 9 connected to the moving mechanism 8 will move on the horizontal plane as the telescopic rod 81 extends or contracts, increasing the effective range of the device on the horizontal plane. And the telescopic rod 81 rotates along with the rotating structure 6 at the same time, increasing the effective range of the device in the vertical direction within the straight-line distance range from the bottom of the telescopic rod 81 of the moving mechanism 8 to the top of the fixture 85. At this time, the auxiliary telescopic rod 83 connected to the telescopic rod 81 through the adapter 82 can also extend or contract, increasing the effective range of the device in space. And the direct sunlight angle changes in the four seasons. At this time, it is necessary to adjust the movement 8 through the above process, so that the convex lens 9 connected to the moving mechanism 8 can converge the sunlight on the solar panel of the photovoltaic power generation unit 1, thereby increasing the light-receiving area of the photovoltaic power generation unit 1 and completing the automatic adjustment of the light-receiving area of the photovoltaic power generation unit 1.

[0030] Embodiment 2

[0031] Please refer to Figures 1-4 , on the basis of Embodiment 1, further, a convex lens 3 is fixedly connected to the top of the support column 2. The two sides of the convex lens 3 are provided with convex structures, and the cross-sectional area of the convex lens 3 is larger than the cross-sectional area of the solar panel of the photovoltaic power generation unit 1.

[0032] Working principle: When the adjusting device for the light-receiving area of the photovoltaic power generation unit is in use, the support column 2 is fixed on the outside of the photovoltaic power generation unit 1. At this time, since the cross-sectional area of the convex mirror 3 is larger than the cross-sectional area of the solar panel of the photovoltaic power generation unit 1, the convex mirror 3 can completely cover the upper part of the photovoltaic power generation unit 1, providing an effective rain-proof function when it rains and completing the rain-proof effect.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
