For the integral cooperative turning of the water distributor, the two support tables are positioned at the same side of the outer water distribution ring.

Furthermore, the two connecting rods rotate coaxially.

In order to improve the supporting strength of the supporting platform, the supporting platform is a triangular supporting platform.

Furthermore, the supporting table comprises a left supporting plate and a right supporting plate, the top of the left supporting plate is connected with the top of the right supporting plate through an installation block, the bottom of the left supporting plate is connected with the bottom of the right supporting plate through a bottom plate, a plurality of installation holes are formed in the bottom plate, and the overall stability of the supporting table is improved.

In order to facilitate installation and fixation of the ball bearing, the ball bearing is positioned between the bearing pressing plate and the installation block and is clamped and fixed by matching the bearing pressing plate and the installation block.

Furthermore, the top of the mounting block is concave, the bearing pressing plate is convex, and the bearing pressing plate and the mounting block form a circular mounting hole for accommodating the ball bearing.

The utility model discloses following beneficial effect has: utilize on-the-spot driving, outer water distribution ring is arranged in on the brace table, then slowly lift by crane water distributor unilateral until vertical state, because whole water distributor is fixed in one by the ball bearing on the brace table, water distributor upper portion is pulled by the driving, the lower part is fixed by two ball bearings, so when whole water distributor is by level to vertical state, the forward coherence force reduces greatly, thereby whole safety of standing up the process has been guaranteed, water distributor's throwing has been avoided, guarantee driving and other equipment steady operation.
