Household Photovoltaic Cell Follow-up Device

technical field

The invention relates to a power generation device, in particular to a household photovoltaic cell light-following device.

Background technique

Solar photovoltaic cells (PVCell), referred to as photovoltaic cells-SolarCell, use the photovoltaic effect to directly convert the sun's light energy into electrical energy. The photovoltaic effect, also known as the "photovoltaic effect", refers to the phenomenon that light causes a potential difference between different parts of an inhomogeneous semiconductor or a combination of a semiconductor and a metal. When sunlight irradiates the photovoltaic cell, the photons of sunlight excite electron-hole pairs in the cell, and the electrons and holes move to the two ends of the cell respectively. If the external path is formed, a current will be formed to generate electrical energy. The power generation efficiency of photovoltaic cells mainly depends on the amount of light energy received by the solar receiver panel.

Photovoltaic cells have the advantages of non-pollution, green environmental protection, not limited by the geographical distribution of resources, no danger of resource depletion, power generation nearby, high energy quality, short time to obtain energy, and reliable power supply system. However, the energy distribution density irradiated by photovoltaic cells is small, and the obtained energy is greatly affected by weather conditions such as four seasons, day and night, and cloudy or sunny. Therefore, the most important thing to improve the power generation efficiency of photovoltaic cells is to increase the amount of light received by the solar panels of photovoltaic cells per unit time.

Experimental data show that photovoltaic cells follow the rotation of sunlight, and the efficiency of photovoltaic cells of the same scale is increased by 35% to 40%. The adoption of tracking technology can make the shoulders of daily power generation peaks wider and flatter, and the peak time period is longer, reducing the impact on the power grid. In order to improve the efficiency of photovoltaic cells in some foreign photovoltaic fields, more than a dozen photovoltaic panels are connected in series and parallel to perform light source tracking. Due to the large size, the investment in transmission, drive and control systems is more than 5 times higher than that of fixed installations.

In order to realize the purpose, technical solutions and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

As shown in Figure 1 and Figure 2, the household-use photovoltaic cell light-following device of the present invention has a specific structure as follows:

Household photovoltaic cell light follower, its structure is as follows: the output shaft of the motor 1 used to control the rotation of the cam set 2 is connected to the shaft of the cam set 2, and the cam set that drives the solar panel 4 to rotate left and right with the rotating rod 5 as the axis center 2 is two cams with opposite installation directions, the two cams are coaxially connected, the lower end of the rotating rod 5 that can rotate around the bracket 6 is fixed on the bracket 6, and the solar panel 4 that can rotate around the rotating rod 5 is installed on the rotating rod 5 , the upper end of the telescopic rod 3 is fixed on the rotating rod 5 top, and the lower end is fixed on the support 6.

In the figure, motor 1 is an automatic control motor that controls the rotation of the cam. The best choice is the sensor adjustment motor, which can be a timing option to make the cam set reach a certain angle, or rotate according to light control induction. Cam group 2 is that two cams are installed in opposite directions to achieve the purpose of rotating the solar panel 4. The distance between the two cams or the size of the cam and the eccentric size can be adjusted to make the rotation angle of the solar panel larger or smaller. The telescopic rod 3 among the figure, it can be set the telescopic scale of two fixed stalls in summer and winter, can adjust once according to the azimuth of the sun in summer and winter each year, also can use electric adjustment. In the figure, the solar panel 4 is installed on the rotating rod 5 and can rotate around the rotating rod 5 to realize daily angle adjustment. In the figure, the rotating rod 5 is fixed on the support 6 and can rotate around the support to realize the adjustment of the angle of inclination in summer and winter every year. Support 6 among the figure is integral supporting device.

The invention achieves two rotations:

The first rotation is the rotation of the overall tilt angle. The cycle is one year. It can be adjusted once a year according to the sun's orientation in summer and winter. It can set the telescopic scales of two fixed gears in summer and winter. Generally, the telescopic adjustment is manually adjusted. Bar 3 also can use sensor, setting program multi-scale automatic expansion and contraction adjustment, adopting sensor setting program mode control is conventional technology. The second rotation is the rotation of the solar panel. Through the cooperation of the cam group 2, the solar panel 4 can rotate left and right around the rotation rod 5 as the axis center. The cycle is one day. Which position can also be installed with a sensor, which can be automatically adjusted by sensing light. It is a conventional technology to use the sensor to set the program control method.
