Mechanized folding and unfolding device for flat net and net bag

Abstract

The invention relates to a mechanical collecting and releasing device for a flat net and a net bag, which comprises a frame, an overhauling platform is horizontally arranged on the frame, an auxiliary mechanism is arranged on the overhauling platform, a net distributing mechanism and a tensioning mechanism are arranged below the overhauling platform, the net distributing mechanism and the tensioning mechanism are horizontally arranged on the frame, and the net distributing mechanism and the tensioning mechanism are arranged on the frame. The frame is further provided with a net drawing mechanism, and the net drawing mechanism is located below the net distributing mechanism. According to the mechanical folding and unfolding device for the flat net and the net bag, mechanical folding and unfolding of the net bag and the flat net are achieved by additionally arranging mechanical equipment, the working efficiency can be greatly improved, sudden outbreak marine organisms can be effectively dealt with, stable operation of a nuclear power unit is guaranteed, impurity removal and unfreezing of a maintenance platform can be achieved, and the maintenance efficiency is improved. Slipping of maintainers caused by impurities or freezing is prevented, and the maintenance safety is improved.

Description

technical field [0001] The invention relates to a mechanized retractable device for flat nets and net pockets, belonging to the field of pre-filtration of circulating water in nuclear power plants. Background technique [0002] my country's nuclear power plants use seawater as a cold source to provide cooling water for nuclear power plants. In order to ensure that the cooling water can meet the requirements, the water source needs to be pre-filtered. The existing pre-filtering measures mostly use some temporary interception facilities to intercept marine organisms by artificially deploying net pockets and flat nets. Manual operations are often required. The efficiency is low, the operation is complicated, and there is no timely and effective response to the sudden outbreak of marine organisms. [0003] Therefore, there is a need for a mechanized retractable device for flat nets and nets. By adding mechanized equipment to realize the mechanized retraction of nets and flat ne...
