Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
As shown in fig. 1, fig. 2 and fig. 4, the present invention provides a photovoltaic tracker rotor with a full distribution of components, for increasing the power generation amount of the photovoltaic tracker and increasing the utilization rate of the field, the photovoltaic tracker rotor with a full distribution of components comprises a photovoltaic component 100, a component fixing mechanism 200, a light diverging mechanism 300 and a main shaft 400, wherein:
the plurality of photovoltaic modules 100 are sequentially arranged along the main shaft 400, and each photovoltaic module 100 is fixedly connected to the top of the main shaft 400 through a module fixing mechanism 200 and has an inclination angle facing the incident direction of light;
the front end of each photovoltaic module 100 extends into the shadow coverage area at the back of the previous photovoltaic module 100 along the light incidence direction, the light diverging mechanism 300 is disposed at the rear end, and the light diverging mechanism 300 can diverge the received incident light to the shadow coverage area.
In the process of implementing the photovoltaic tracker rotor, considering that, for example, when the distance between the photovoltaic modules 100 is set to be small, the shadow shielding of the photovoltaic modules 100 can cause the disconnection of a whole row or a whole column of the photovoltaic modules 100, which affects the power generation efficiency, under the background that the cost of the photovoltaic modules is gradually reduced, the applicant creatively proposes that the light scattering mechanism is used for scattering light (as shown in fig. 1 and 2), so that a light source is obtained in a shadow coverage area, which is not high in illumination intensity, but effectively enables the whole row or the whole column of the photovoltaic modules 100 to form a passage, and further, the power generation efficiency under the condition of shadow shielding is improved.
In specific implementation, the distance between the front photovoltaic module 100 and the rear photovoltaic module 100 along the incident direction of the light can be set in various embodiments. For example, as shown in fig. 1 and fig. 2, in order to reduce the pitch of the photovoltaic modules 100 and ensure the photoelectric conversion efficiency of the individual photovoltaic modules 100, the front ends of the photovoltaic modules 100 in the light incident direction may be aligned with the rear end of the photovoltaic module 100 in front, that is, the photovoltaic modules 100 may be laid without a pitch.
In particular implementations, the light diverging mechanism 300 may be arranged in a variety of embodiments. For example, as shown in fig. 3 and 4, since the concave lens 310 has excellent light divergence performance and high cost performance, and is not easily damaged in use, the light divergence mechanism 300 may include a concave lens 310 and two lens holders 320, wherein: the concave point of the concave lens 310 is located at the center along the incident direction of the light ray, and the width of the concave lens is the same as that of the photovoltaic module 100; the two lens brackets 320 are disposed on two sides of the rear end of the photovoltaic module 100, and the concave lens 310 is fixed between the two lens brackets 320. Further, as shown in fig. 3, in order to ensure the light transmittance of the light diverging mechanism 300 and avoid blocking light, the concave lens 310 may be fixedly connected to the two lens holders 320 through EVA transparent glue. In addition, the two lens holders 320 may also be transparent material holders, so as to further improve the light transmittance. When the lens support 320 is disposed, the U-shaped lens support 320 may be selected, one side of the opening of the U-shaped lens support 320 may be fixed to the rear end of the photovoltaic module 100, and two sides of the concave lens 310 are fixed by the U-shaped support.

Further, as shown in fig. 2, in order to ensure that the front bracket 210 and the rear bracket 220 are stably connected to the main shaft 400, the front bracket 210 and the rear bracket 220 may both have a base attached to the top of the main shaft 400, and meanwhile, the base may be connected to the main shaft 400 in various embodiments, for example, each base may be fixedly connected to the main shaft 400 by the U-bolt 230 because the U-bolt 230 has high connection stability and is convenient to install. As another example, the base may also be field welded to the spindle 400. Further, in order to avoid the base of the front bracket 210 and the base of the rear bracket 220 from affecting the arrangement of the adjacent photovoltaic modules 100, the base of the front bracket 210 and the base of the rear bracket 220 may be oppositely arranged, that is, both the base and the base are arranged in the coverage area of each photovoltaic module 100, so as to avoid affecting the installation of the front and rear modules.
In particular implementations, the rear bracket 220 may be provided in a variety of embodiments. For example, as shown in fig. 1 and 2, in order to ensure the bearing capacity and the connection stability of the rear bracket 220, the rear bracket 220 may be disposed perpendicular to the main shaft 400, and the top end of the rear bracket is connected to the rear end of the bottom of the photovoltaic module 100.
In particular implementations, the concave lens 310 may be arranged in a variety of embodiments. For example, as shown in fig. 3, in order to ensure light emission performance of the concave lens 310, the concave lens 310 may be disposed in parallel with the photovoltaic module 100.
In particular embodiments, the spindle 400 may be selected for use in various embodiments. For example, in order to ensure that the main shaft 400 is stably connected with the fixing mechanism and the contact area between the main shaft 400 and the fixing mechanism is increased, the cross section of the main shaft 400 may be square, so as to effectively improve the operational reliability of the photovoltaic tracker rotor.
