The invention provides a locking release mechanism applicable to a solar battery array. The locking release mechanism comprises a left-handed screw rod, a right-handed screw rod, a left-handed lock hook, a right-handed lock hook, a left lock ring, a right lock ring, a left sliding rail, a right sliding rail, a shell, a worm, a worm wheel, a rotating shaft, a drive bevel gear, a left driven bevel gear, a right driven bevel gear, a driving unit, a left screw rod supporting piece and a right screw rod supporting piece. The gear worm + orthogonal bevel gear + screw rod sliding rail + conical lock hook principle is adopted, the driving unit is used for receiving an external actuating signal so as to drive the worm to rotate; by virtue of gear worm drive, the drive bevel gear is driven to rotate; by virtue of bevel gear drive, the left-handed screw rod and the right-handed screw rod are respectively driven to rotate, so that the left-handed lock hook and the right-handed lock hook are respectively driven to move along the left sliding rail and the right sliding rail, hooking and unhooking of the left lock ring and the lock ring which are fixedly arranged on a solar panel are realized, and repeated locking and release of the solar panel are finished.
