Abstract

A passive locking system for solar trackers having a connecting rod (110), a guide lock (120) and a suspension mechanism applied to a pin (116) integral with the connecting rod (110). The connecting rod (110) is joined at a first end (112) to a rotation profile (200) of the solar tracker. The second end (114) of the connecting rod (110) has the aforementioned pin (116). The guide lock (120) is elongated, fixed to a support post and has two upper (122) and lower longitudinal edges (124) and an inner guide rail (126). The upper and lower longitudinal contours of the guide rail (126) have teeth (127) along the same. The system has a suspension mechanism that damps the movements of the pin (116) within the guide rail (126) substantially perpendicular to the contours of the rail.

Abstract

Disclosed is a locking device for a solar tracker, comprising at least one hydraulic cylinder on the solar tracker with photovoltaic modules on a shaft that can be actuated to rotate in order to orient the modules towards the sun, with respect to a support post supporting the modules, the cylinder having two independent chambers for containing oil. Between the chambers is disposed a piston to which respective rods are connected, the rods extending through the chambers and projecting from the ends of the cylinder, and the chambers communicate with each other by means of conduits, between which is arranged a solenoid valve that controls the passage of oil between the chambers when the piston moves. According to the invention, the device is designed to be disposed on the solar tracker such that one end of a rod is connected to the rotation shaft and the other end is freely moveable, the cylinder being fixed to the post.
