Description

Technical Field

[0001] The utility model relates to the technical field of submersible flow pushers, in particular to a submersible flow pusher for sewage treatment. Background Art

[0002] Submersible flow thrusters are mechatronic devices that are widely used in sewage treatment plants. Existing submersible flow thrusters are conventionally installed at the bottom of the pool. The entire set of equipment mainly includes the flow thruster host, underwater guide rails, lifting devices, lifting bases, etc. The underwater guide rails are welded together with the coupling base where the flow thrusters are placed. The lifting device lifts the flow thruster host, slides down along the guide rails to the coupling base, and is supported on the bracket to be installed in place.

[0003] In order to ensure the stable operation of the equipment, the guide rails and coupling bases installed on the bottom of the conventional pool need to be fixed on the bottom of the pool. They are generally fixed by embedded parts welding or expansion bolts. They can only be installed when there is no water in the pool and the bottom of the pool is clean. For newly built pools, this is easy to meet, but for projects that need to be upgraded and renovated and are in operation, the required installation conditions cannot be met. When there is water in the pool, the installers cannot go down to the bottom of the pool for installation operations. If it is necessary to install it in the conventional pool bottom fixing method, it is necessary to drain the pool and remove the sludge on the bottom of the pool before normal installation. The installation cost is high, the cycle is long, and the installation risk is high: the installers need to be equipped with corresponding safety facilities, and carry installation tools to go down to the bottom of the pool several meters deep for installation operations.

[0004] Conventional flowmakers installed at the bottom of a pool will immediately cause equipment vibration, noise, damage, and even failure of the entire system once the pool bottom installation becomes loose or the connection reliability fails. When there is water in the pool, although the flowmaker can be lifted up for maintenance, it is inconvenient to maintain and repair the loose guide rails and bases underwater. The pool still needs to be drained and cleaned, resulting in a large amount of time and manpower and material resources being wasted, affecting the normal operation of the sewage treatment plant and causing economic losses. Therefore, it is urgent to propose corresponding submersible flowmakers for sewage treatment to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and to provide a submersible flow propeller for sewage treatment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A submersible flow promoter for sewage treatment comprises a counterweight base, a mounting seat, a lifting assembly and a flow promoter main unit, wherein a support column is integrated on the top of the mounting seat, and the lifting assembly is integrated at the open end of the support column, a guide rail and a side bracket are fixedly connected to the top of the counterweight base, a coupling base is fixedly connected to the top of the side bracket, the flow promoter main unit is placed on the top of the coupling base, and a roller sleeve slidably connected to the guide rail is fixedly connected to the outside of the flow promoter main unit, a notch is provided on the side of the roller sleeve away from the flow promoter main unit that matches the connecting seat, and a rolling wheel slidably matched with the guide rail is integrated on the inner surface wall of the longitudinal end of the roller sleeve, a rotating seat is fixedly connected to the bottom of the support column, and the outer surface wall of the rotating seat is rotatably connected to the inner surface wall of the mounting seat through a bearing, and a locking portion for axial locking of the rotating seat is integrated on the outer surface wall of the mounting seat.

[0008] Preferably, the locking portion comprises an outer seat fixedly connected to the outer wall of the mounting seat, a positioning rod is screwedly connected between the outer seat and the mounting seat, and an open end of the positioning rod abuts against the outer wall of the rotating seat.

[0009] Preferably, a connecting seat is fixedly connected to the top of the guide rail, and a lower bracket is fixedly connected to the bottom of the counterweight base.

[0010] Preferably, a mainframe bracket is fixedly connected to the top of the counterweight base, and an open end of the mainframe bracket is fixedly connected to an outer wall of the coupling base.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the present application, the coupling base is fixed on the side bracket, the side bracket is connected to the lower end of the guide rail as a whole, and is installed on the counterweight base by bolts. The counterweight base is provided with a lower bracket and a main engine bracket on both sides. After the above installation is completed, it is hoisted into the pool as a whole and placed stably on the bottom of the pool. The upper end of the guide rail is fixed to the side wall of the pool top walkway with a connecting seat and bolts, and the support column is fixed to an appropriate position on the pool top walkway by bolts. The flow pusher main engine is combined on the coupling base, and the roller sleeve on its outer side is set on the track. The lifting chain on the lifting hoist is connected to the flow pusher main engine, and the flow pusher main engine can be lifted up and lowered. The lifting hoist is operated to make the flow pusher main engine slide down along the guide rail into the pool and take place on the coupling base. In this way, the flow pusher main body can be lifted and placed independently, and the flow pusher does not need to be connected to the bottom of the pool through fasteners, thereby ensuring the convenience of subsequent overall disassembly and maintenance of the flow pusher.

[0013] 2. In the present application, after the flow-propelling device body and the roller sleeve are lifted to a suitable height by means of a lifting hoist, the support column is moved, and the support column drives the rotating seat to rotate and cooperate with the mounting seat through the bearing. The support column links the lifting hoist and the flow-propelling device main unit until the propeller main unit is deflected to a suitable angle. The positioning rod is then rotated to screw it into the outer wall of the mounting seat, and the axial locking of the support column is achieved through the contact friction between the positioning rod and the rotating seat, thereby ensuring the convenience of taking and placing the flow-propelling device main unit.

In this way, the flow pusher main machine 6 can be lifted and placed independently, and the flow pusher as a whole does not need to be connected to the pool bottom through fasteners, so as to ensure the convenience of subsequent disassembly and maintenance of the flow pusher as a whole.

[0025] It should be noted that the lifting assembly 11 here adopts a conventional lifting hoist, and the structure will not be described in detail here.

[0026] Specifically, Figure 2 and Figure 4 The outer wall of the rotating seat 14 is rotatably connected to the inner wall of the mounting seat 9 through a bearing 15, and the outer wall of the mounting seat 9 is integrated with a locking part for axially locking the rotating seat 14.

The support column 10 is fixed to an appropriate position on the pool top walkway by bolts. The flow-making device mainframe 6 is combined with the coupling base 5, and the roller sleeve on its outer side is set on the guide rail 3. The lifting chain on the lifting hoist is connected to the flow-making device mainframe 6, and the flow-making device mainframe 6 can be lifted up and lowered. The lifting hoist is operated to make the flow-making device mainframe 6 slide down along the guide rail 3 into the pool. The base 5 is put into place, so that the main unit 6 of the flow-maker can be lifted and placed independently, and the flow-maker as a whole does not need to be connected to the bottom of the pool by fasteners, so as to ensure the convenience of subsequent disassembly and maintenance of the whole flow-maker.
