Embodiment 1

[0022] see figure 2 , diagram 2-1 , a device that tracks sunlight

[0023] In the warp tracking part, the bottom end of the battery panel frame 1 is hinged to the bottom plate of the trolley 3 through a hinge point 2, wherein the upper end of the battery panel frame 1 is hinged to the rocker 10 through a two-dimensional hinge point, and the other end of the rocker 10 is hinged to the crank 9 Hinged in a one-dimensional hinged form warp tracking section. In addition, according to the change of the season, by moving the hinged position of the rocker 10 on the crank 9 and locking and fixing it with the locking member 4, the daily pitch angle ∠θ swing of the battery panel frame 1 can be adjusted to adapt to different The daily change in solar elevation angle over the seasons. Realize that the battery panel frame 1 automatically tracks the illumination of the sun at any time.

[0024] The circular track 6 of the tackle in the latitudinal tracking part adopts a negative track ...

Embodiment 2

[0028] see image 3 , Figure 3-1 , a device for tracking sunlight, the working surface of the damping curve 8 in the latitudinal tracking part is a coaxial annular surface with the track 6, and the piston rod on the damping cylinder 7 is realized by cooperating with the working surface of the damping curve 8 in the axial direction Control the speed of sliding on the track 6 around the central axis 5 of the tackle 3 carrying the battery board frame. Others are with embodiment 1.

Embodiment 3

[0030] see Figure 4 , a device for tracking sunlight, the working surface of the damping curve 8 in the latitudinal tracking part is an annular surface that coincides with the track 6, and the piston rod of the damping cylinder 7 fixed on the pulley 3 is also determined by the working surface of the damping curve 8 in the axial direction. Surface cooperation, to realize the control of the moving speed of the trolley 3 carrying the battery board frame on the track 6 around the central axis 5. In this example, a wheel on the tackle 3 is directly fixed on the piston rod of the damping cylinder 7, so that it doubles as the motion support of the tackle 3 and the damping speed-limiting effect. Others are with embodiment 1.

Abstract

The invention relates to a device for tracking solar irradiation, which is designed for solving the technical problems of small structural scale, low running benefit, poor capacity of resisting windy sand, inapplicability in environments with larger windy sand, high maintenance cost, extra energy consumption, high running failure rate, short service life of components and the like existing in the traditional dynamic solar illumination tracking system. The device for tracking solar irradiation mainly comprises a battery board frame, a warp tracking part and a weft tracking part, wherein the weft tracking part comprises an annular track with a negative gradient, a track central shaft and a tackle; and the warp tracking part is formed by fixing the bottom end of the battery board frame on the tackle through an articulated joint. The invention has the characteristics and advantages that the device for tracking solar irradiation is suitable for occasions needing to automatically track the solar illumination in real time and large structure fabrication, is used for large-scale photovoltaic power stations and can steadily and reliably run by only utilizing the geopotential without needing extra energy sources. The invention is especially suitable for windy sand environments in the northwest of China and has the characteristics of simple installation, stable running, high efficiency, low cost, windy sand resistance, easy maintenance and the like.

Description

Technical field: [0001] The invention relates to a solar energy collection device, in particular to a device for tracking sunlight. It is suitable for large-scale photovoltaic power plants, especially for use in the windy and sandy environment in Northwest my country. Background technique: [0002] At present, most photovoltaic systems adopt the form of installation with fixed angles of panels, so that the efficiency of receiving light is very low. And existing dynamic tracking system mainly adopts high-speed rotating parts to realize tracking, as: announcement number: CN101135913, CN101201628, CN2533435, involved " solar energy full-automatic tracking turntable ", " fixed solar receiver automatic tracking device of elevation rotating shaft "; " Sun synchronous tracking device" and other devices, so the equipment has poor anti-wind and sand capabilities, and is not suitable for use in environments with large wind and sand, and the installation and maintenance costs are high...
