Abstract
A vehicle and method for cleaning parabolic trough solar collectors (2) by means of a motorized vehicle (1) which includes a water tank (4); front (5) and rear (6) cleaning arms, with a telescopic part having several sections, coupled at one end to a pivoting head (8) which supports a rotary cleaning brush (9) and comprises spray nozzles (10), as well as proximity sensors (12) for the brushes (9). It comprises the same number of front and rear transverse guide rails (13) which include a linear movement means (14) coupled, by means of a pivot (15), to the cleaning arms (5, 6). The brushes (9) are movable in relation to the head (8) by means of a shaft (21) actuated by a retraction actuator (27) for overcoming obstacles (26).
