Description

MULTIAXIAL MOVEMENT DEVICE, PARTICULARLY FOR SOLAR PANELS AND THE LIKE The present invention relates to a multiaxial movement device, particularly for solar panels and the like. In the renewable energy sector, the use is known of solar followers applied to photovoltaic panels, the function of which is to orient an individual solar panel over the course of the day so that the solar rays stroke the panels perpendicularly. In this way it is possible to optimize the yield of the solar panel. More specifically, such solar followers are typically provided with two servomotors which are responsible, respectively, for the east-west orientation of the solar panel and for the inclination of the panel with respect to the vertical. In fact, from the point of view of the Earth, the sun, in addition to moving from east to west, over the course of the day, rises and falls with respect to the horizon. Such conventional followers are not devoid of drawbacks, among which is the fact that the two servo-actuators can move out of phase over time, and so will not ensure that the sun is correctly followed. Another drawback of conventional followers consists in that, since there are two servo-actuators with associated kinetic mechanisms, the risk of a machine shutdown owing to a malfunction is very high. A further drawback of conventional followers consists in that they require energy to make the two servo-actuators operate, with consequent drop in yield with respect to the ideal yield. The aim of the present invention consists in providing a multiaxial movement device, particularly for solar panels and the like, that is capable of making it possible to follow the parabolic movement of the sun and at the same time the alignment from sunrise to sunset, while simultaneously varying the inclination of the solar panel to anticipate the maximum irradiation on the terrestrial axis, in so doing making it possible to maximize the energy yield. This aim and other objects which will become better apparent hereinafter are all achieved by a multiaxial movement device, particularly for solar panels and the like, which comprises a container body which contains inside it gearmotor means which are kinematically connected to a supporting shaft which partly protrudes from said container body and is associated with a body to be moved; characterized in that said supporting shaft: - is rotatably associated with said container body about its longitudinal axis, remaining integral with it in translation; - is hollow; - is hinged to said body to be moved at its portion that protrudes from said container body eccentrically with respect to said longitudinal axis along a first pivoting axis which is transverse to said longitudinal axis so as to be integral in rotation therewith with respect to said longitudinal axis, and - is kinematically associated with said gearmotor means at its portion that is internal to said container body so as to make said body to be moved rotate about said longitudinal axis with respect to said container body as a result of the rotation of said supporting shaft about said longitudinal axis; and characterized in that it comprises an actuation rod which is slideably accommodated in the internal cavity of said supporting shaft along said longitudinal axis so as to protrude from said supporting shaft outside said container body with a first end, which is hinged to a linkage which in turn is hinged to said body to be moved along a second pivoting axis which is parallel to and spaced apart from said first pivoting axis, and inside said container body with a second end which is opposite to said first end; said actuation rod being integral in rotation with said supporting shaft and being associated, at said second end, with cam means so that it can slide along said supporting shaft as a result of the rotation of said supporting shaft about said longitudinal axis with consequent rotation of said body to be moved about said first pivoting axis concurrently with the rotation of said body to be moved about said longitudinal axis.
