Embodiment 1

[0033] See figure 1 As shown, the first embodiment of the present invention provides an online cleaning device for intake and drainage tunnels, including: a drive unit 2; at least two cleaning assemblies 3, each of which is respectively arranged on the drive unit 2 and Connected with the drive unit 2; a support base 1 located below the drive unit 2 and connected with the drive unit 2, the support base 1 is used to support the drive unit 2 and stabilize each of the cleaning components 3; the The drive unit 2 is used to drive the support base 1 to move linearly along the water flow direction of the tunnel under the impulsive force of the water flow, and to drive each of the cleaning components 3 to rotate circumferentially along the tunnel; The crown of the cleaning assembly 3 can be resiliently held against the inner wall of the tunnel, and is used to peel off the pollutants attached to the surface of the tunnel.

[0034] Specifically, the support base 1 includes a support bas...

Embodiment 2

[0046] The online cleaning device for intake and drainage tunnels provided by Embodiment 2 of the present invention also includes a connecting device 4, and the connecting device 4 is a transmission connector 41. In this embodiment, the transmission connector 41 is a worm gear transmission. In other In the embodiment, the transmission connector 41 can be one of a right-angle reducer, a T-type reducer or a T-type steering box.

[0047] See figure 2 As shown, in this embodiment, the connecting device 4 is a transmission connector 41, the transmission connector 41 includes a transmission gear 411 and a worm 412, and the transmission gear 411 is sleeved outside the drive shaft 21, so The central axis of the worm 412 is perpendicular to the central axis of the drive shaft 21. The outer surface of the transmission gear 411 is provided with tooth grooves, and the outer surface of the worm 412 is provided with thread grooves. For docking, the worm 412 is connected with the support b...

Embodiment 3

[0062] The present invention provides an online cleaning method for intake and drainage tunnels, the main steps of which are: placing the above-mentioned online cleaning device for intake and drainage tunnels in the intake and drainage culverts, so that the crown of the cleaning assembly 3 can be elastically held against the Turn on the operation switch of the nuclear power plant, and the water flow in the culvert drives the impeller 22 to rotate, thereby driving the drive shaft 21 to rotate. The drive shaft 21 directly drives the cleaning assembly 3, and the cleaning assembly 3 strips the pollutants from the surface of the tunnel. The support seat 1 moves linearly along the water flow direction of the tunnel under the action of the driving force.

[0063] In this embodiment, when the support base 1 and the driving unit are only connected by the bearing bracket 13, the support base 1 is directly pushed by the water flow and moves linearly along the water flow direction in the t...

Abstract

The present invention provides an intake-outlet tunnel on-line cleaning device and method. The intake-outlet tunnel on-line cleaning device comprises a drive unit, as well as at least two washing assemblies and a support block connected to the drive unit. The drive unit is used for driving the support block and the washing assemblies to perform linear movements under the pushing of impact force of water flows in the direction of water flows in the tunnel, and driving the washing assemblies to rotate circumferentially along the tunnel; and the crowns of the washing assemblies are resiliently propped against the inner wall face of the tunnel for peeling off contaminants adhered on the surface of the tunnel. The support block is used for supporting the drive unit and stabilizing each cleaning assembly. According to the invention, the equipment is driven to perform circumferential and axial movements by using impact force of water flows in the tunnel, on-line cleaning of aquatic organisms in the tunnel can be realized without external fuel or electricity, the cleaning cost is reduced, and the convenience in use of the equipment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant marine structures cleaning, and more specifically, relates to an online cleaning device and method for intake and drainage tunnels. Background technique [0002] The pollutants attached to the marine structures of nuclear power plants will have many adverse effects on nuclear power plants. For nuclear power plants with long-distance drainage tunnels, the adhesion of pollutants in the tunnels will increase the power consumption of the plant, reduce the micro-increased output of the units, and reduce the operating performance and reliability of nuclear power units. Therefore, necessary measures must be taken to deal with the problem of pollutant adhesion in drainage tunnels . [0003] At present, there are three main antifouling measures for drainage tunnels of nuclear power plants: [0004] 1. Inhibit the growth of pollutants by adding chemical agents, but this method is only applicab...
