Solar tracker with movement in two axes and actuation in only one of them

Abstract

According to FIG. 6, it consists of a solar tracking device with two axes of rotation, which is actuated only in one of them by virtue of the incorporation into the mechanism of a support bar of adjustable length (8), which is articulated at its two ends and anchored via one side to the body that tracks the sun (4) and via the other side to an adjustable support (5) joined to the base of the actual tracker or to the ground. In turn, the bar is equipped with a shock-absorbing spring system (10) that allows it to be operated as a dynamic control element for the whole assembly.

Description

[0001]The present invention relates to a solar tracking device with two axes of rotation, which is actuated in only of them, by virtue of the incorporation into the mechanism of a support bar of adjustable length, which is articulated at its two ends and anchored at one side to the body carrying out the solar tracking, and at the other to an adjustable support joined to the base of the actual tracker or to the ground. In turn, the bar is equipped with a shock-absorbing spring system that allows it to be operated as a dynamic control element for the whole assembly.BACKGROUND OF THE INVENTION[0002]Solar tracking devices with two axes (orientation movement—tracking of the azimuth—and inclination movement—tracking of the elevation-) are known. These devices seek maximum energy collection from solar radiation by making the incidence of the solar rays be perpendicular throughout the day to the collection surface of the thermal or photovoltaic device.[0003]The two rotations determining the...

Benefits of technology

[0015]1. ARM OF ADJUSTABLE LENGTH: FIG. 4 describes, only by way of example, the components of the arm in its most complex configuration. It is seen in the sectioned view that at the two ends it incorporates two ball and socket joints (1) and (2), restricting the translations between the lashed bodies, but not rotations. It also has a manually or automatically actuated mechanical, electrical, magnetic, hydraulic or pneumatic extension-compression mechanism (3). It furthermore incorporates a shock-absorbing spring system (4) responsible for attenuating both the forces that can act on the tracker at specific moments (gusts of wind) and for reducing vibrations and resonances to which the tracker might be exposed by external actions (for example, incidence of the wind). Simpler configurations not incorporating the elements for adjusting the length and / or suspension elements, depending on the features that the tracker is to have, can be chosen.

Problems solved by technology

Compared with a tracker system with only one axis, the tracker with two actuated axes is more expensive to construct and maintain and less reliable since it incorporates more elements that can break down.
