Description

A parabolic trough vertical axis tracking solar collector

technical field

The utility model relates to a solar heat collector, in particular to a parabolic trough vertical axis tracking solar heat collector suitable for heating and heating in rural areas and remote mountainous areas.

Background technique

In view of this, there is an urgent need to design a tracking solar collector suitable for heating and heating in rural areas and remote mountainous areas.

Utility model content

Aiming at the above-mentioned problems and defects in the prior art, the purpose of this utility model is to provide a parabolic trough vertical axis tracking solar collector to improve heat collection efficiency and facilitate heating and heating for rural and mountainous areas.

The technical solution adopted by the utility model to solve the technical problem is a parabolic trough vertical axis tracking solar heat collector, which includes photovoltaic battery board I, photovoltaic battery board II, reflector, vacuum tube, vacuum tube bracket I, vacuum tube bracket II, cold water Pipe, hot water pipe, stepper motor, coupling, control unit, battery, rotating spindle, front fixed bracket, rear fixed bracket;

It is characterized in that the hot water pipe and the cold water pipe are respectively installed at the front and rear ends of the vacuum pipe, the vacuum pipe is installed on the vacuum pipe support I and the vacuum pipe support II, and the vacuum pipe support I and the vacuum pipe support II are installed on the rotating spindle, The photovoltaic cell panel I and the photovoltaic cell panel II are respectively mounted on the left and right ends of the reflector, the reflector is mounted on the rotating shaft, and the rotating shaft is mounted on the front fixing bracket and the rear fixing bracket; the photovoltaic cell The solar panel I and the photovoltaic panel II convert light energy into electrical energy and store it in the storage battery. The storage battery is used to supply power to the stepping motor. The control unit, storage battery and stepping motor are installed at the front of the reflector; Shaft adapters are used to connect the shafts of rotating spindles and stepper motors.

The working principle of a parabolic trough vertical axis tracking solar heat collector of the utility model is:

First, according to the north-south direction of the collector installation, set the angle between the main axis of rotation and the horizontal plane as the local latitude, then the cold water enters the vacuum tube from the end of the cold water pipe, the reflector condenses the light to the vacuum tube and heats it, and the photovoltaic panel I And the photovoltaic panel II converts sunlight energy into electrical energy and stores it in the battery. When the angle of sunlight is deflected, the intensity of sunlight received by the two photovoltaic panels on the left and right of the reflector changes, resulting in There is a potential difference in the potential, and the control unit controls the rotation direction of the stepper motor according to the potential difference. When viewed at the end where the control unit is installed, if the potential difference between the photovoltaic panel I and the photovoltaic panel II is greater than zero, the stepper motor rotates clockwise. If the potential difference between photovoltaic cell panel I and photovoltaic cell panel II is less than zero, the stepper motor rotates counterclockwise; if the potential difference between photovoltaic cell panel I and photovoltaic cell panel II is equal to zero, the stepper motor is stationary.

The beneficial effect of the utility model is that sunlight at different angles can be tracked along the east-west direction, a continuously high heat collection effect can be obtained, and the daily average heat collection efficiency can be significantly improved, and the power to drive the mirror to rotate is entirely from the electric energy transformed by the photovoltaic battery panel , without the need to arrange additional power supply and its circuit. It has the characteristics of convenient installation, high-efficiency heat collection, and energy saving. It is especially suitable for regional heating and heating in rural areas and remote mountainous areas.
