Underwater propeller installation method

Abstract

The invention discloses an underwater propeller installation method. In the prior art, the biochemical pool must be subjected to production stopping, water discharge and sewage clearing before the installation of the underwater propeller in the biochemical pool, such that the time and the labor are consumed, the potential safety hazard exists, and the sewage treatment plant can be subjected to economic loss. A purpose of the present invention is to solve the problems in the prior art. According to the present invention, the underwater propeller is installed in the biochemical pool through thespecial well channel type fixed bracket in the case of the non-stop production of the biochemical pool; and compared to the method in the prior art, the method of the present invention has the following characteristics that the construction period is short, the well channel type fixed bracket can be rapidly lifted in place to complete the installation after the production, the biochemical pool canbe constructed without the stop production of water discharge and sewage discharge, the impact on the sewage treatment plant is minimized, the construction is safe, and the safety of the constructionworker can be ensured at a maximum while the installation quality requirements can be met.

Description

technical field [0001] The invention relates to an installation method of an underwater thruster. Background technique [0002] The biochemical sewage tank of the sewage treatment plant needs to be installed with underwater propellers. In the existing technology, when installing underwater propellers, it is generally necessary to completely shut down the biochemical sewage tank and drain the sewage. The slide rail is fixed and installed in the pool. [0003] When installing underwater thrusters, there are the following disadvantages: [0004] 1. The environment is harsh, the space is confined, the air quality is extremely poor, and there is a risk of suffocation. [0005] 2. The height in the pool is high, and there is a risk of falling from a high place. [0006] 3. The pool is wet, and there is a risk of electric shock when performing live operations such as welding. [0007] And there is also the disadvantage of inconvenient maintenance in the later stage after instal...

AI Technical Summary

Problems solved by technology

[0011] The technical problem to be solved by the present invention is to provide an installation method for an underwater thruster, and solve the problem that in the prior art, when an underwater thruster is installed in a biochemical pool, it is necessary to stop production, drain water, and clean up the biochemical pool first, which is time-consuming and laborious, and has potential safety hazards. At the same time, it will also bring economic losses to the sewage treatment plant.
