The sliding block is in clearance fit with the sliding rod.
The double-end lead screw thread is bounded by the first bearing seat, and the thread directions of the left side and the right side are opposite.
The photovoltaic support is four in number, and the shape, size are the same.
The working principle of the invention is as follows: when needs expand the photovoltaic support, electric putter work drives the photovoltaic support and expandes gradually, because the cooperation of support slider and support guide rail, each photovoltaic support is linear motion, and the stopper plays limiting displacement, prevents that the photovoltaic support breaks away from each other. When the photoelectric detection device detects that the sun altitude changes and the pitch angle of the photovoltaic support needs to be changed, the photoelectric detection device transmits information to the controller, the controller controls the first motor to work, the double-end lead screws on the two sides of the first bearing seat are opposite in thread direction, so that the two lead screw nuts move in different directions all the time, the pitch angle of the photovoltaic support is changed, and the universal wheels are used for automatically adjusting the distance between the rear bottom plate and the front bottom plate when the photovoltaic support is unfolded and folded and the pitch angle of the photovoltaic support is changed. When the photovoltaic support needs to be folded, the motor of the electric push rod and the lead screw motor rotate in the opposite direction.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that: (1) the device can fold the photovoltaic bracket when not used or needing to be transferred and stored, and is convenient to carry, transport and store; (2) the photoelectric detection device is installed, and the photoelectric detection device is matched with the controller, the double-end lead screw and the motor of the electric push rod for comprehensive use, so that the pitch angle of the photovoltaic support can be adjusted by tracking sunlight in real time, and the power generation efficiency is improved.
