Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a submersible sewage pump coupling device. Background Art

[0002] As we all know, submersible sewage pump is the abbreviation of submersible sewage pump. It is mainly used in municipal engineering, building construction, industrial sewage and sewage treatment occasions to discharge sewage, wastewater and rainwater containing solids and long fibers. The two commonly used installation methods of submersible sewage pumps are coupling installation and mobile installation. Among them, coupling installation is suitable for submersible sewage pumps of various specifications and is the most commonly used installation method for submersible sewage pumps. Coupling installation is to connect the pump to the pipeline through a coupler. The pump is easy to disconnect from the outlet pipeline. When the water pump is overhauled, it can be lifted by a lifting device.

[0003] The coupling device of the submersible sewage pump includes a coupler, a coupling flange, a guide rod, etc. The submersible sewage pump is connected to the coupler, and the coupler can slide up and down along the guide rod. The coupling flange is connected to the outlet pipe. During installation, the submersible sewage pump and the coupler are slid down along the track. When the coupling device descends to the bottom of the guide rod, the coupler is aligned with the coupling flange. The weight of the submersible sewage pump makes the coupler fit with the coupling flange. The submersible sewage pump can start working after it is started. When the submersible sewage pump needs to be repaired, the maintenance personnel do not need to go into the water to work, but only need to lift the pump body for maintenance.

[0004] The existing coupler is fixedly provided with a guide groove that matches the guide rod. After the coupler is slid up and down many times, the guide groove on the existing coupler is easily worn, and the matching degree between the guide groove and the guide rod is reduced. At this time, the coupler is prone to shaking during the lifting process. After the coupler and the coupling flange are aligned, the sealing performance is reduced, and during installation, the guide groove and the guide rod need to be aligned up and down for installation, which is inconvenient to install and has low practicality. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a submersible sewage pump coupling device, which can effectively prevent the coupler from shaking, improve the sealing performance, and facilitate the installation of the coupler and the guide rod.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a submersible sewage pump coupling device, comprising a coupler and a sewage pipe, a mounting frame is provided at the bottom of the sewage pipe, a coupling flange is provided at one end of the sewage pipe, two guide rods are provided on the coupling flange, the coupler is installed on the guide rods, the coupler and the coupling flange match, connecting blocks are provided on both sides of the coupler, the same bidirectional screw is rotatably installed on the two connecting blocks, rotating blocks are provided at both ends of the bidirectional screw, both sides of the bidirectional screw are connected to limit blocks by threads, a slide groove is provided on the coupler, each of the limit blocks is provided with a sliding block matching the slide groove, and guide grooves are provided on the two limit blocks.

[0009] Furthermore, the diameter of the guide groove is larger than the diameter of the guide rod.

[0010] Furthermore, a flange plate is provided at the other end of the coupling flange.

[0011] Furthermore, the coupler is provided with a plurality of bolts for mounting a submersible sewage pump.

[0012] Furthermore, the coupler and the coupling flange are both provided with sealing rubber rings that match each other.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a submersible sewage pump coupling device, which has the following beneficial effects:

[0015] The coupling device of a submersible sewage pump is provided with a connecting block, a bidirectional lead screw, a limit block, a guide groove, a guide groove and a sliding block. The spacing between the two guide grooves can be adjusted by rotating the bidirectional lead screw. When the guide groove is worn, the guide groove and the guide rod can still be tightly fitted by rotating the bidirectional lead screw, thereby effectively preventing the shaking of the coupler during the descent process and effectively preventing the sealing performance of the coupler and the coupling flange from being reduced. During the installation process, the bidirectional lead screw is rotated to bring the two limit blocks closer, thereby expanding the installation range of the guide groove. There is no need to align the guide groove and the guide rod up and down for installation like a traditional coupler, thereby facilitating the installation of the guide groove and the guide rod.
