s2, installing the worm (3): firstly, fixedly mounting two bearings on a worm (3) by utilizing an inner ring, then screwing one end which is not connected with a driving motor (4) into a lower cavity, respectively fixing a first plugging piece (13) and a second plugging piece (14) with corresponding outer rings of the bearings until the distances between the two bearings and the port of the lower cavity are equal, and connecting a sealing ring in a compression state to realize sealing by penetrating a corresponding adjusting hole (16) through an adjusting piece (15) and connecting the sealing ring with a shell (1);

s3, fixing the position of the worm wheel (2): the sealing main part (10) is matched with the sealing auxiliary part (11) through a fastener (12) to realize the sealing of the upper cavity;

s4, adjusting the center distance: the first plugging piece (13) and the second plugging piece (14) are unscrewed for one to two circles, the sealing rings are still in a compression state, the first plugging piece (13) and the second plugging piece (14) can move relative to the shell (1) of the lower cavity under the action of the outside, the two wedge-shaped sliding blocks (20) move towards the center by adjusting the two-way screw (17) so as to gradually support the first plugging piece (13) and the second plugging piece (14), the displacement quantity of the first plugging piece (13) and the second plugging piece (14) can be directly observed to meet the zero-clearance condition of the worm wheel (2) and the worm (3) through the scale variation quantity on the ratchet bar (20), and the ratchet bar (20) is locked by the locking block (19) under the action of the spring so as to release the load of the two-way screw (17;

s5, installing a driving motor (4): fixedly connecting the output end of the driving motor (4) with the worm (3) at the second plugging piece (14), and then penetrating a waist-shaped hole in the adjusting seat (6) by using a bolt and fixing the driving motor (4) and the adjusting seat (6);

s6, checking: after the drive motor (4) is started to check that the transmission of the worm wheel (2) and the worm (3) reaches the standard, the first protective cover (21) and the second protective cover (22) are covered at corresponding positions.

10. A gap adjusting method in the operation process of a photovoltaic power generation double-shaft output rotation driving device is characterized by comprising the following steps:

the first (13) and the second (14) plugging pieces are unscrewed for one to two circles, the sealing rings are still in a compression state, the first (13) and the second (14) plugging pieces can move relative to the shell (1) of the lower cavity under the action of the outside, the two wedge-shaped sliding blocks (20) move towards the center by adjusting the two-way screw (17) to gradually support the first (13) and the second (14) plugging pieces, the displacement on the ratchet bar (20) can be directly observed through the scale variation on the ratchet bar (20) to meet the zero-clearance condition of the worm wheel (2) and the worm (3), and the ratchet bar (20) is locked by the locking block (19) under the action of the spring to release the load of the two-way screw (17).
