[0003] However, the motor needs to consume electric energy. Therefore, part of the electricity generated by the solar energy will be consumed by the motor, which reduces the power generation efficiency; at the same time, most photovoltaic panel tracking devices are installed outdoors on a large scale. , so the motor needs to be overhauled regularly, and some motors will suddenly fail due to the instability of the motor movement

The invention discloses a photovoltaic panel tracking device by the utilization of liquid thermal expansion. The photovoltaic panel tracking device comprises a horizontal base, a spinning shaft support and a liquid thermal expansion device, wherein the horizontal base is composed of multiple square tubes, the spinning shaft support is installed on the horizontal base, and the liquid thermal expansion device is installed on the horizontal plane and located on the outer side of the horizontal base. The liquid thermal expansion device comprises a lifting piston rod perpendicular to the horizontal plane, an expansion oil heat collection box which is hollow inside and filled with liquid thermal expansion media, and a hydraulic cylinder installed on the expansion oil heat collection box. The photovoltaic panel tracking device is simple in structure, convenient to install and arrange and low in investment cost; in the working process, sunlight irradiates the expansion oil heat collection box to enable the volume of expansion oil to be increased, and the expansion oil is pressed into the hydraulic cylinder to drive the piston rod to ascend and descend and finally drive a spinning shaft to rotate without other power. The whole device can be free of maintenance, so that it is avoided that a motor is adopted for a traditional photovoltaic panel tracking device and consumes energy itself, and besides manpower and material resources are saved for overhauling.
Description
technical field [0001] The invention relates to a tracking device, in particular to a photovoltaic panel tracking device utilizing thermal expansion of liquid. Background technique [0002] In a traditional photovoltaic panel tracking device, generally at least one set of power mechanism is required to drive the photovoltaic panel to rotate, and the power mechanism is usually a motor. [0003] However, the motor needs to consume electric energy. Therefore, part of the electricity generated by the solar energy will be consumed by the motor, which reduces the power generation efficiency; at the same time, most photovoltaic panel tracking devices are installed outdoors on a large scale. , so it is necessary to regularly overhaul the motor, and some motors will fail suddenly due to the instability of the motor movement. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a photovoltaic panel tracking device using liquid...
