Nuclear power plant seawater cooling system gate sealing groove cleaning device

Abstract

The invention discloses a nuclear power plant seawater cooling system gate sealing groove cleaning device which comprises a hoisting head, the hoisting head is fixedly installed in the middle of the upper portion of a rack assembly, a guide wheel assembly is fixedly installed at the corner of the rack assembly, a linear guide rail is fixedly installed on the lower portion of the rack assembly, and four linear sliding blocks are arranged on a sliding block assembly. The sliding block assembly and the linear guide rail form a linear motion pair, the pan-tilt camera is fixedly installed on the side face of the sliding block assembly, a base of the six-joint underwater mechanical arm is fixedly installed on the sliding block assembly, the air jet tool is fixedly installed at the tail end of the six-joint underwater mechanical arm, and the auxiliary camera is fixedly installed on the outer wall of the last joint of the six-joint underwater mechanical arm. The gate sealing groove cleaning device has the beneficial effects that the whole gate sealing groove cleaning device is of a truss type structure, the six-joint underwater mechanical arm can be conveyed to different positions through the crane and the guide wheel assembly, and all positions of the whole gate sealing groove can be covered through cooperation of the mode.

Description

technical field [0001] The invention belongs to a cleaning device, in particular to a cleaning device for a gate sealing groove of a seawater cooling system of a nuclear power plant. Background technique [0002] Nuclear power plants require a large amount of cooling water during operation, and most nuclear power plants use open channels or open channels and tunnels for cooling water intake. There are multiple gates in the seawater cooling system of the nuclear power plant, located at the end of the open channel and at both ends of the tunnel, to control the opening and closing of seawater, and to control the flow of seawater. Due to the large size of the tunnel, the opening and closing of the gate is mostly in the form of a sealing groove. When the cooling water needs to be closed, the gate needs to be lifted into the sealing groove by a crane, and the gate can be pressed by the pressure of the water and the gravity of the gate itself. into the sealing groove for sealing. ...

AI Technical Summary

Problems solved by technology

There are also nuclear power plants that use underwater floating robots for cleaning. Due to the fast water flow in the tunnel, it will affect the work of underwater robots. Therefore, the cleaning work can only be completed when the machine is shut down or the flow rate is low, which will affect the normal operation of the nuclear power plant.
