Description

A blade-type method for removing marine deposits in nuclear power water intake tunnels

technical field

The invention relates to the technical field of water intake tunnel cleaning equipment, in particular to a blade-type method for removing marine deposits in nuclear power water intake tunnels.

Background technique

At present, during the use of nuclear power water intake tunnels, there will be a lot of marine organisms attached in the long run. The attachment of marine organisms will reduce the water intake per unit section of the tunnel, which will affect the work of the entire nuclear power plant. The marine organisms attached to the tunnel are generally composed of shellfish, and their shells and secretions have a certain degree of hardness. The inner wall of the water intake tunnel is made of reinforced concrete, and the cross section of the tunnel is generally circular or horseshoe-shaped. To remove attached marine organisms, not only work and cleaning efficiency must be considered, but also the protection of the inner wall of the concrete must be considered.

At present, the removal of marine deposits in nuclear power water intake tunnels uses the walking wheel assembly installed on the frame to make the entire equipment move normally in the tunnel. The frame plays the role of fixing the tool mounting seat and track wheels, and the tool assembly is controlled by a hydraulic cylinder. The height of the cutter is to make it contact with the inner wall of the tunnel. The hydraulic cylinder drives the serrated cutter to move back and forth to shovel off the marine organisms attached to the inner wall of the tunnel. The cutter components are evenly distributed on the frame to ensure full coverage of the tunnel section cleaning area. Although this cleaning method can replace manual cleaning of marine organisms in the tunnel, it brings about significant changes in cleaning efficiency. However, there are dead angles in the tunnel cleaning, and the tunnel cleaning is not thorough, especially for tunnels with a horseshoe-shaped cross section. The attached marine organisms cannot be cleaned according to the actual conditions of the tunnel, and the cleaning effect is poor.

The prior art tunnel sea organism cleaning machines cannot perform directional cleaning without dead ends according to the shape of the tunnel section, and the tunnel cleaning is not thorough, which not only has poor cleaning efficiency and low work efficiency, but also easily damages the reinforced concrete on the inner wall of the tunnel.

Contents of the invention

The purpose of the present invention is to provide a blade-type method for removing marine deposits in nuclear power water intake tunnels in view of the deficiencies in the prior art. The multi-stage retractable electric blade is used as a cleaning tool for marine deposits, and the air bag controls the cleaning machine. The depth position of the dive, the propeller is the power device for the cleaning machine to walk underwater, and the blade-type underwater cleaning machine is integrated into one, and the propeller power device is turned on to control the forward speed of the machine so that the machine moves forward to the direction of the target well , obtain the attachment position of sea organisms through the imaging device, and after reaching the attachment point of sea organisms, turn on the hydraulic foot to fix the cleaning machine, adjust the inflation and exhaust of the airbag, control the depth position of the cleaning machine, and open the multi-stage retractable electric blade, which can be adjusted according to the tunnel. According to the actual situation, the attached marine organisms are directional cleaned, which greatly improves the work efficiency and cleaning effect. The directional cleaning without dead ends can be carried out according to the shape of the tunnel section, so that it can be accurately in place, targeted, and does not damage the reinforced concrete and structure of the inner wall of the tunnel. Simple, easy to use, high cleaning efficiency, and has certain application prospects.

The specific technical solution for realizing the object of the present invention is: a blade-type method for removing marine deposits in nuclear power water intake tunnels. The depth position where the machine dives, the propeller is the power device for the cleaning machine to walk underwater, and the camera and laser scanner are the image devices, which are integrated on the frame of the steel structure for the underwater cleaning machine. The machine is placed in the middle well In the tunnel, turn on the propeller power device to control the forward speed of the machine, so that the machine moves forward to the direction of the target well. By adjusting the gas in the airbag, the depth of the cleaning machine's dive is controlled to reach the sea creature attachment position collected by the camera and laser scanning. A multi-stage retractable electric cutter head is used to remove marine organisms. The underwater cleaning machine uses a control chip to control electric blades, propellers, air bags, cameras and laser scanners to achieve directional removal of marine organisms in water intake tunnels.

The control chip is connected with a computer arranged outside the water intake tunnel through a control cable or wireless communication, so that the underwater cleaning machine can directionally remove marine deposits in the water intake tunnel.

Compared with the prior art, the present invention has the advantages of directional cleaning of the attached marine organisms without dead ends according to the actual conditions of the tunnel, so as to be accurate, targeted, and not damage the reinforced concrete on the inner wall of the tunnel. The structure is simple, easy to use, and the cleaning efficiency is high. , the production cost is low, the work efficiency is greatly improved, and the utility model has certain application prospects.
