Problems solved by technology

Although high tracking accuracy can be guaranteed in this way, due to the law of the sun's movement, its angular velocity in the two directions of horizontal angle and pitch angle is uneven, which makes the control program very large and complicated, and the cost of system production and maintenance is high. Very high and unstable, which also hinders the large-scale application of tracking technology

Embodiment 1

[0035] like Figure 1 ~ Figure 2 As shown, the battery panel fixing frame 1 is a welded frame structure (or a combined aluminum profile frame structure) for fixing the battery panel. In order to reduce wind resistance, the battery panels can be installed in parallel, but there is a certain gap between them, and they can also be installed at a certain inclination angle with the battery panel fixing frame.

[0036] The support frame 2 is a welded columnar steel structure, the lower end of the support frame is fixed to the foundation through fastening bolts, and the upper end of the support frame 2 is connected to the battery panel fixing frame 1 through a three-dimensional rotating member 3 .

[0037] like figure 2 As shown, the three-dimensional rotating component 3 includes a left and right angle rotation axis 31 and a pitch angle rotation axis 32 arranged in a cross shape, and the two axes are integrated by welding. According to whether the two axes are on the same plane, ...

Embodiment 2

[0049] Such as image 3 As shown, the difference from Embodiment 1 is that the transmission part is an integrally cast semi-circular arc body 5, and tooth-shaped protrusions are provided on the outer edge of the semi-circular arc body 5; the two ends of the semi-circular arc body 5 Directly welded or bolted on the left and right angular rotation axis 31 , and the two connection points are symmetrical about the pitch angle rotation axis 32 .

[0050] A driving device 42 ' is installed in the middle part of support frame 2, and this driving device 42 ' comprises motor and worm gear reducer, and gear 43 is installed on the power output shaft of worm gear reducer, and this gear is just in time with semicircular arc body 5 The teeth mesh with each other and are used to transmit power, which is the transmission wheel. The movement of the panel fixing frame 1 in the pitch direction can be controlled by the driving device 42'.

[0051] The left and right corner tracking components a...

Embodiment 3

[0054] Such as Figure 4 As shown, the difference from the second embodiment is that: the two ends of the semicircular arc body 5 are provided with pin holes radially and coaxially along the semicircular arc body 5, and at the same time, the battery panel fixing frame 1 corresponds to the pin holes. A pair of side lugs are provided at the position, and the two side lugs are located on the extension line of the left and right angle rotation axes, and are symmetrical about the pitch angle rotation axis 32 . Pin holes are also provided on the side ears, and the semicircular body 5 is just hinged on the battery board fixing frame through the round pin 62 . And there are some positioning holes 61 on the semi-circular arc body 5, a series of positioning holes are evenly distributed on the semi-circular arc body to form a positioning structure, the number of positioning holes can be set according to the situation, the more the number, the higher the positioning accuracy. A bracket i...

Abstract

The invention relates to a sunlight-tracking double-shaft device and a control method thereof. The sunlight-tracking double-shaft device comprises a battery board fixing bracket, a support bracket, a pitch angle rotation driving member and a left and right angle rotation driving member, wherein the battery board fixing bracket is connected with the support bracket through a three-dimensional rotating mechanism consisting of a pitch angle rotating shaft and a left and right angle rotating shaft which are distributed in a crisscross shape; and the pitch angle rotation driving member and a left and right angle tracking drive member control the coordinated rotation of the pitch angle and the left and right angles according to a control method, thereby enabling the working surface of a battery board in a tracking device to accurately correspond to the position of the sun and achieving the purpose of sunlight tracking. The sunlight-tracking double-shaft device has the characteristics of simple and reasonable structure, low energy consumption for running, high running precision, simple control program and the like, and is convenient for installation and daily maintenance.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, specifically a dual-axis tracking sunlight device that can automatically adjust the sun-reflecting surface through simple clock program control, so that the sunlight always maintains the best incident angle, and maximizes the efficiency of solar energy utilization. and its control methods. Background technique [0002] Most of the current solar photovoltaic power generation systems are fixed installation of solar panels. This structure can only ensure that the sunlight is irradiated at the best angle at a certain time on a certain day of the year, so the utilization rate of sunlight is relatively low. Due to different lighting conditions in different regions, the use of dynamic tracking technology can increase photovoltaic power generation by more than 30% - 50%. However, most of the existing solar tracking technologies have high costs due to complex structures and other reasons...
