Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel bearing devices, in particular to a photovoltaic panel bearing device for photovoltaic energy storage. Background Technique

[0002] Photovoltaic panels are used to convert solar energy into electrical energy. As an environmentally friendly power generation device, they are attracting more and more attention. When installing existing photovoltaic panels, they are mostly fixed, that is, the angle of the photovoltaic panel remains unchanged, resulting in limited solar energy absorbed by the photovoltaic panel and low photoelectric conversion efficiency. Generally, a photovoltaic panel bearing device will determine the installation inclination angle of the photovoltaic panel according to the local latitude and longitude to ensure that the photovoltaic panel receives the maximum solar radiation throughout the day when it is at this inclination angle, thereby ensuring the power generation efficiency of the photovoltaic panel. However, this method cannot adjust the angle of the photovoltaic panel according to the real-time light direction. Based on this situation, it is necessary to design a photovoltaic panel bearing device for photovoltaic energy storage to adjust the inclination angle of the photovoltaic panel according to the light direction. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0020] Referring to Figures 1 - 4 , the photovoltaic panel 1 realizes the adjustment of the angle through the support assembly 4. The support assembly 4 is generally installed on the backlight surface of the photovoltaic panel 1. There are many specific implementation methods for the support assembly 4. The following gives two implementation methods.

[0021] First, referring to Figures 1 - 3 , the first implementation method of the support assembly 4 includes a base 401 hinged to the photovoltaic panel 1 on one side, a lead screw 402 horizontally rotatably connected to the base 401, a first motor 403 fixed to the base 401 and used to provide driving force for the lead screw 402, a block 405 threadedly connected to the outer surface of the lead screw 402, and a support rod 404. One end of the support rod 404 is hinged to the block 405, and the other end of the support rod 404 is hinged to the back of the photovoltaic panel 1. When it is necessary to adjust the pitching angle of the photovoltaic panel 1, the first motor 403 drives the lead screw 402 to rotate, so that the block 405 can move along the lead screw 402, dragging the bottom of the support rod 404 to move. When the bottom of the support rod 404 moves, the hinged angle between one side of the photovoltaic panel 1 and the base 401 changes, and the pitching angle of the photovoltaic panel 1 changes.

[0022] The support assembly 4 can also be added with a mounting shell 407 rotatably connected to the lower part of the base 401 through a bearing 406 on the basis of the above, and a second motor 408 located inside the housing and capable of applying rotational power to the base 401, so as to realize the adjustment of the rotation angle of the photovoltaic panel 1. When the rotation angle of the photovoltaic panel 1 needs to be adjusted, the second motor 408 drives the base 401 to rotate, so that the photovoltaic panel 1 on the base 401 rotates, realizing the adjustment of the rotation angle of the photovoltaic panel 1. Through the cooperation of the above first motor 403 and second motor 408, the pitching angle and rotation angle of the photovoltaic panel 1 can be adjusted.

[0023] Second, referring to Figure 4 , the second implementation method of the support assembly 4 includes a pitching motor 411 whose driving end is connected to the back of the photovoltaic panel 1, a support column 410 fixed to the pitching motor 411, and a rotation motor 409 used to drive the support column 410 to rotate. When it is necessary to adjust the angle of the photovoltaic panel 1 in this implementation method, the pitching motor 411 can drive the photovoltaic panel 1 to adjust the pitching angle, and the rotation motor 409 can drive the support column 410 and the photovoltaic panel 1 as a whole to rotate. Therefore, the cooperation of the pitching motor 411 and the rotation motor 409 can realize the adjustment of the pitching angle and rotation angle of the photovoltaic panel 1.

[0024] Although the above two embodiments of the support assembly 4 are listed in the present utility model, in actual production, there may be other ways to achieve the angle adjustment of the photovoltaic panel 1, which will not be listed one by one here.

[0025] The main innovation of the present utility model lies in that the photovoltaic panel 1 can automatically adjust its angle according to the direction of light. Specifically, by installing a light-sensitive ring 2 and a light-shielding body 3 on the light-receiving surface of the photovoltaic panel 1, and then cooperating with a controller 5, the photovoltaic panel 1 can be adjusted to the angle perpendicular to the light direction at all times. The light-sensitive ring 2 is composed of a plurality of light sensors 201 (such as photodiodes) arranged in a ring, and the light-shielding body 3 is located at the center of the ring formed by the plurality of light sensors 201 and extends vertically upward from the light-receiving surface of the photovoltaic panel 1. Refer to Figure 5 , when the light ray A1 irradiates on the light-shielding body 3, the shadow A2 of the light-shielding body 3 will cover some of the light sensors 201 on the light-sensitive ring 2. The light sensors 201 covered by the shadow A2 and the light sensors 201 that can receive the light irradiation (not covered by the shadow) will generate different signals. The controller 5 judges the current light direction according to the signals received by different light sensors 201, such as Figure 6 , the light sensors 201 transmit the signals to the controller 5, and the controller 5 can judge the current light direction according to the signals received by the light sensors 201, and then issue a control signal to control the support assembly 4, so that the support assembly 4 adjusts the photovoltaic panel 1 to the angle perpendicular to the light direction. At this time, each light sensor 201 on the light-sensitive ring 2 can receive the light irradiation and generate the same signal. At this time, the photovoltaic panel 1 is in the state perpendicular to the light direction. In this state, the photovoltaic panel 1 receives the most light and the photoelectric conversion efficiency is the highest.

[0026] It can be seen that compared with the installation of the traditional fixed-angle photovoltaic panel 1, the present utility model can adjust the angle of the photovoltaic panel 1 in real time by setting the support assembly 4 that can adjust the angle of the photovoltaic panel 1, cooperating with the controller 5, the light-sensitive ring 2 and the light-shielding body 3, so as to ensure the high-efficiency operation of the photovoltaic panel 1.

[0027] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
