Photovoltaic tracking system with end position protection function

Abstract

Photovoltaic tracking system with end-position protection function, characterized in that it comprises: a torsion tube (1), wherein adjacent torsion tubes (1) form a continuous structure in the longitudinal direction by means of a connecting bridge (2); a support base (3), wherein a first locking area (33) and a second locking area (34) are provided on the support base (3), the support base (3) comprises a support arm (31), the connecting bridge (2) is rotatably connected to the support arm (31), and a recess (21) for the passage of the support arm (31) is provided in the base of the connecting bridge (2); a locking head (4), wherein the locking head (4) is rotatably mounted on the base of the connecting bridge (2), wherein the connecting bridge (2) has a passage position and a first locking position when passing the support base (3); wherein in the passage position the locking head (4) is inclined through the support base (3). passes through;In the first locking position, the locking head (4) is inclined against the first locking area (33) or the second locking area (34) to prevent the connecting bridge (2) from driving the torsion tube (1) to a further rotation; the connecting bridge (2) switches between the through position and the first locking position by rotating backwards.
