Automatic cleaning and trash blocking net device for power station seawater water-intaking open channel

Abstract

The invention relates to the technical field of nuclear power station maintenance, and particularly discloses an automatic cleaning and trash blocking net device for a power station seawater water-intaking open channel. The device is arranged in the water channel, dirt is intercepted through a concentric-square-shaped trash blocking net, moreover, the dirt in the water channel is taken away from the water surface by rotating, when the dirt rotates along with the concentric-square-shaped trash blocking net to the position between a driving roller and a follow-up roller, high-pressure water mistsprayed out of a back flushing nozzle is used for washing dirt which is adhered to the outer surface of the concentric-square-shaped trash blocking net away from a net body, the dirt is scraped awaythrough a back flushing baffle to be further collected onto a dirt conveying belt, and the dirt is transported to a collecting box at the top of a bank slope through the dirt conveying belt. Accordingto the device, electric control automatic cleaning is adopted to replace manpower to automatically intercept and clear the dirt in the seawater water-intaking open channel of the power station, so that the clearing and maintaining efficiency is improved, and the problem that the influences of weather and people on the existing trash blocking and trash removing construction activities are generally large is solved.

Description

Technical field [0001] The invention belongs to the technical field of nuclear power plant maintenance, and in particular relates to a device for automatically cleaning trash interception nets for seawater intake channels of power plants. Background technique [0002] During operation, there are unforeseen contaminants in the open sea water intake channels of nuclear power plants, such as seaweed, fish, jellyfish, garbage, shell fragments, etc. The existing decontamination methods are basically blocked by trash nets and manually cleaned regularly. form. In the seawater intake open channel, several straight-face nets are arranged horizontally as trash nets to block the entire cross-section of the flow channel in multiple layers. The apertures of the trash nets are reduced from the outside to the inside in order to filter and intercept the dirt layer by layer. When the weather is small, a dedicated person will drive the boat to salvage the dirt in the net to the cabin. Due to the...

AI Technical Summary

Problems solved by technology

If the ship cannot be launched in bad weather, the dirt will not be cleaned up in time, and the excessive accumulation of dirt will pass through the trash net and enter the drum net, resulting in failure of the cold source of the power station and affecting the safe operation of the power station

Therefore, when there is a lot of dirt in the water area, it needs to be cleaned up every day, which will consume a lot of labor costs, and a lot of water surface operations will also increase the risk of drowning and heat stroke
