Description
Technical field
The invention belongs to nuclear plant water intaking mouth service technique fields, and in particular to a kind of sea work intake bottom silt purging
Tool.
Background technology
The water intaking of nuclear power station seawater intake is used as to carry out by dredger with power station cooling water, each overhaul intake
Dredging works, and cannot be introduced into intake structures since dredger volume is excessive, leads to 5 meters before intake structures of marine site silt
Mud can not be cleared up, and to overcome traditional dredging to limit to and deficiency, develop a kind of special bottom silt wiping tool
Invention content
The object of the present invention is in view of the shortcomings of the prior art, provide it is a kind of can with the comprehensive of effective guarantee marine site dredging,
Ensure intake seawater flow, the extra large work intake bottom silt wiping tool of the safe operation of protection power station.
The technical scheme is that：
A kind of sea work intake bottom silt wiping tool, it is characterised in that：Including air inlet, upper gas-guide tube, handle, under
Gas-guide tube, counterweight and duck bill hole, the upper gas-guide tube upper end is equipped with air inlet, lower end is equipped with downtake, and the handle is set to
On upper gas-guide tube, the counterweight is set to downtake lower end, and the duck bill hole is set to counterweight lower end.
Present apparatus main body is single layer straight pipe.
It is described to be designed to that pagoda connector is convenient and high-pressure air pipe is attached including air inlet.
The weight of the counterweight is 5kg.
The beneficial effects of the invention are as follows：
The present invention is that overcome traditional dredging to limit to comprehensive with deficiency effective guarantee marine site dredging, it is ensured that intake
Seawater flow, the safe operation of protection power station.
Description of the drawings
Fig. 1 is a kind of extra large work intake bottom silt wiping tool
Specific implementation mode
The present invention is further introduced below in conjunction with the accompanying drawings：
A kind of sea work intake bottom silt wiping tool, including air inlet 1, upper gas-guide tube 2, handle 3, downtake 4,
Counterweight 5 and duck bill hole 6,2 upper end of upper gas-guide tube is equipped with air inlet 1, lower end is equipped with downtake 4, and the handle 3 is set to upper
On gas-guide tube 2, the counterweight 5 is set to 4 lower end of downtake, and the duck bill hole 6 is set to 5 lower end of counterweight.
Present apparatus main body is single layer straight pipe.
It is described to be designed to that pagoda connector is convenient and high-pressure air pipe is attached including air inlet 1.
The weight of the counterweight 5 is 5kg.
Embodiment
The making of special mud wiping tool is blown for mud before the work water-fetching head structures of field gulf nuclear power station sea
Sweep, the shape of mud wiping tool is "-" type, when design in view of dredging tool to pass through it is artificial transmit up and down, in view of height
Drop is 5 meters, the landing of Accrete clearing device in order to prevent, is convenient to staff again and takes over the firm of tool and be not easy to slide special
Property, mud wiping tool is specially designed as single layer straight pipe, is convenient to transmit up and down, mud wiping tool is divided into two up and down
It is grouped as, top half is air inlet and handle, and the top half of device is the stainless steel tube of an a diameter of Φ 25, in order to increase
Add the air inflow of compressed air, the top contact of top half to make the stainless steel tube of Φ 10, be designed to pagoda connector it is convenient and
High-pressure air pipe is attached, and the lower half portion of Accrete clearing device is the stainless steel tube of Φ 14, and the diameter of upper and lower two parts dredging pipe becomes
Change and is pressurized (intensified pressure) for tube interior to preferably carry out mud purging work, the lower half portion of Accrete clearing device
For the stainless steel tube of Φ 14, there are one round clump weight weight 5kg, round clump weight effects to be to maintain dredging purging dress for outside weldering
The vertical drop set more accurately is put into front of the structures to be purged, another effect of round counterweight prevents seawater bottom
Flow velocity is excessive, and wiping tool can not be fixed, however circular clump weight plays the role of fixed, mud purging work in seawater bottom
Has total length 9m
The head of mud wiping tool head clamp connection high-pressure hose, high-pressure hose other end and air compressor machine
The outlet (0.75MPa) connection, mud blow device is inserted by gas-guide tube ф 25 on mud wiping tool and downtake ф 14
In mud before extra large work water-fetching head structures, operating personnel must both hands help steady handle, prevent the excessive wiping tool of air-flow de-
Hand connects pneumatics electromechanical source and supplies gas, and compressed air is transported to leading in mud wiping tool by high-pressure hose by air compressor machine
Tracheal strips, compressed air are blown out from duckbill nozzle, are put into using wiping tool at the cement Horizon before water-fetching head structures
Mud in, logical upper compressed air cleans out mud before intake strucure, by mud wiping tool to structures before
Cleaning work is purged, the flow of water-fetching head seawater is effectively guaranteed, meets requirement of the power station to inflow, it is effective to protect
It demonstrate,proves, power station unit stablizes the reliability of safe operation.
