The current installation structure of a submersible flow thruster generally consists of a submersible flow thruster main unit, sliding guide rails, guide rail brackets, and a lifting device.

[0003] The patent document with announcement number CN215666748U discloses a lifting device for a submersible flow pusher in a sewage treatment tank. The utility model discloses a lifting device for a submersible flow pusher in a sewage treatment tank, including a lifting frame, a chain and a lifting device. The lifting frame includes a fixed seat, a column and a cantilever. The fixed seat is fixedly installed on the ground, the bottom end of the column is rotatably connected to the fixed seat, and a fixed frame is provided at the top. The bottom end of the cantilever is fixedly connected to the fixed frame by bolts, and the top extends to the sewage tank and is connected to the sprocket. The free end of the chain is used to connect the submersible flow pusher, and the middle part passes through the sprocket and is connected to the lifting device. The lifting device is set on the ground. In the above application document, the top end of the cantilever is rotated to the required direction by rotating the column. However, its rotating column lacks a limiting structure, and it can always rotate. When lifting, the movable rotating column will cause the cantilever to shake, which is not convenient for stable lifting. Utility Model Content

There are two limiting plates 405 and limiting rods 406. The limiting rod 406 is fixedly connected to the upper side of the base plate 1, and the upper side of the support ring 404 is fixedly connected to the insertion rod 407. The limiting assembly 4 also includes a limiting ring 408, which is fixedly connected to the outer surface of the second column 3. A socket 409 is provided below the limiting ring 408. The socket 409 is a through hole that can pass through the socket 409 and the insertion tube 801.

A lifting device 6 is fixedly installed below the cantilever 5, and the lifting device 6 can electrically reel in the rope for lifting, which is a prior art.

[0023] When the above-mentioned equipment is used, the bottom plate 1 is first moved to be placed next to the sewage treatment tank, and then the bottom plate 1 is fixed. At this time, the rotating ring 402 is driven to rotate by the toggle rod 403, so that it descends on the thread 401 on the first column 2. At this time, the support ring 404 will also descend, and the support ring 404 will drive the insertion rod 407 to pull the insert 801 out of the socket 409 on the limit ring 408. At this time, the second column 3 can rotate on the first column 2, thereby adjusting the direction of the cantilever 5 to facilitate the lifting equipment 6 to lift the submersible flow propeller in the sewage treatment tank.
