Title:
RESILIENT MOUNTING PHOTOVOLTAIC TRACKING BRACKET HAVING SELF-LOCKING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/215482
Kind Code:
A1
Abstract:
Disclosed is a resilient mounting photovoltaic tracking bracket having self-locking function, comprising a photovoltaic module support frame for fixing the photovoltaic module, a column (2) for supporting the photovoltaic module support frame, a transfer unit mounted on the column (2), and a drive unit for driving the transfer unit to work. The transfer unit comprises a wire rope (4), a cable clamp, a differential motion spiral wheel (3) and a transmission case (5); the drive unit comprises a drive shaft (6) and a drive and control device (7); and a self-locking structure is provided between the drive shaft (6) and the transmission case (5). Multipoint synergy drive is used to ensure even drive load on the tracking bracket, which greatly reduces the overall torsional deformation of the structure, and thereby guaranteeing the tracking precision of the tracking support and the generating efficiency of the photovoltaic module. Multipoint valid support is used to effectively reduce the vibration response of the structure under wind loading, which improves the safe reliability of the tracking support. Meanwhile, the self-locking at each drive node effectively improve the integral rigidity of the bracket structure as well as the stability and reliability of the structure lock-up.
