Description

a solar tracker

technical field

The utility model relates to a solar energy, in particular to a solar tracker.

Background technique

The battery panel has the ability to directly convert sunlight energy into electricity. In order to capture the maximum amount of sunlight and collect the maximum solar energy, a tracker is connected to the battery, and it is continuous towards the direction perpendicular to the solar radiation. Align the light-absorbing side of the panel so that the panel can absorb maximum solar radiation energy. This is especially important for high-efficiency panels with centralized batteries, and current trackers are typically dual-axis tracking systems with linear actuators for elevation control and azimuth control for azimuth control. gear or linear motors. However, the gear motor is expensive, and the cost of producing the tracker is high. At the same time, the tracker system is installed on a pillar, which is large in size and heavy in weight and difficult to disassemble.

Contents of the invention

Aiming at the defects and deficiencies in the above-mentioned prior art, the purpose of this utility model is to provide a solar tracker with simple structure, convenient operation and easy popularization and application.

The technical solution for realizing the purpose of the above-mentioned utility model is a solar tracker, including a frame, a base, a telescopic rod I, a telescopic rod II, a vertical rod, a stepping motor, and a gear box, and a tripod is installed under the frame, The lower ends of telescopic rod I, telescopic rod II and vertical rod are fixed on the base, and their upper ends are respectively connected with the triangular bracket installed under the frame through universal joints. The telescopic rod I, telescopic rod II, vertical rod The rods are triangularly distributed on the base, the gear box is installed on the base, and the stepping motor is installed on the gear box.

The lower end of the vertical rod is fixed on the base through the fixing seat.

The gear box is fixed on the base by set screws.

The working principle of the utility model solar tracker:

The solar tracker of the utility model connects the base and the frame through the fixed pole to limit the position of a point of the frame, and the telescopic rod I and the telescopic rod II connect the base and the other two points of the frame, and a plane is determined by three points. One point fixed controls the angle of the solar panel by controlling the height of the two points connected by the telescopic rod, so that the solar panel can fully absorb sunlight.

The angle of the pitch angle of the solar panel can be changed by stretching or shortening the telescopic rods I and II with the same length, and the angle of the azimuth angle of the solar panel can be adjusted by changing the length of the two rods when the lengths of the two telescopic rods are not equal.

Compared with the prior art, the utility model has the advantages that:

The tracker of the utility model is mainly composed of two telescopic rods, a vertical rod, a frame and a base. The structure is simple, the cost is low, and a plane is determined according to three points, and the overall system structure is stable and rigid.
