Embodiment approach

[0060] The first embodiment refers to a one-dimensional tracker, which is most commonly employed in flat photovoltaic panels. Referring to the diagram shown in Figure 1, the Polar Axis is used as a structural beam and is supported by two ball bearings 3 and 4 (or any other type of bearing housing) together with its base to rotate around the axis. The solar collection panel 2 is fixed on the pole shaft 1 and rotates with it. The bearing 3 is fixed via its seat on a rotatable hinge 7 which is subsequently fixed on the base 6 . The bearing 4 is fixed via its base on a support structure frame 8 which is fixed on the fixture 5 . The length of the frame 8 and its height on the fixing part 5 can be adjusted so that the inclination angle between the polar axis and the horizontal corresponds to the latitude angle of the installation location. like figure 2 As shown, chain gear 9 is driven by motor / worm gear assembly 14 which in turn drives chain 11 . Both ends of the chain 11 are ...

Abstract

The present invention provides a polar axis tracking device of solar collector, wherein the tracking device comprises the following components: the polar axis which is used as a structural beam and is rotatable, a panel which is fixed to the polar axis and rotate along with the polar axis, a chain which has two ends that are horizontally fixed to the polar axis, a chain gear which is matched with the middle part of the chain, and a drive device which drives the chain gear to rotate. The drive device drives the chain gear to rotate. The chain gear drives the chain to move thereby driving the polar axis and the panel to rotate.

Description

【Technical field】 [0001] The present invention belongs to the field of solar energy in a broad sense, and specifically refers to the field of solar tracking systems of photovoltaic cell panels and concentrated solar collectors, especially the field of polar axis solar tracking systems. 【Background technique】 [0002] The present invention refers to a solar collector, especially a polar axis tracking system device, to track the movement of the sun relative to the earth, so as to achieve higher efficiency and lower cost in collecting solar energy. The invention is applied to flat photovoltaic panels and focused photothermal or photovoltaic devices. [0003] Photovoltaic solar panels are widely used in residential or commercial solar applications. Due to the movement of the sun relative to the earth, the sunlight irradiated on the fixed photovoltaic panel has different incident angles at different times of the day or at different times of the year. Such incident light reduces...
