Abstract
The invention discloses a method and device for regulating abrasive jet. The device mainly comprises a water jet generation system, an abrasive mixing system and a monitoring control system. The method and the device mainly involve the following three operation modes: a demolition and rescue operation mode, a cutting operation mode and a fire extinguishing operation mode. According to the method and the device, an ultrahigh frequency electromagnetic wave radar monitor monitors the cutting depth of abrasive jet in real time, and transmits the cutting depth information and the radar reflection signal intensity information to a controller in real time, when the abrasive jet cuts through an object or reaches a specified cutting depth, the controller gives an instruction to timely cut off the abrasive supply, relieve water pressure and turn off the power, thus effectively preventing abrasive jet overcutting and other problems. Especially in the abrasive jet demolition and rescue field, the method and the device have important significance in protecting survivors from jet damage.
Description
Technical field
The present invention relates to abradant jet technical field, in particular to a kind of regulate and control the method for abradant jet and device.
Background technology
After since the sixties in 19th century, abradant jet is applied to oil well drilling, simple by system, cost is low, stock-removing efficiency advantages of higher, its cleaning, rust cleaning, the operation such as cutting and fractured rock is widely used.Fire incident, terrorist attack, earthquake, tsunami etc. threaten the sudden accident of public safety frequently to occur in all parts of the world in recent years.This kind of disaster often all can cause the destruction of building, and have personnel in building overhead space generally after being ruptured and survive.Disaster relief generally requires orcible entry building ruins and then rescue survivor, but the main equipments such as existing excavator cannot meet basic demand quick and safe flexibly, and for cutting the traditional specialty instrument such as rig of mixed earth, impacting brill etc. cannot the effective metal material such as cutting steel plate, reinforcing bar.Abroad there is the relevant device utilizing abradant jet to carry out Post disaster relief at present, and abradant jet also shows excellence in the field such as Post disaster relief, fire extinguishing, but at present application mostly adopt artificial feel to assess depth of cut and effect, abrasive material can not be regulated and controled by it, the supply of abrasive material can not be stopped in time after abradant jet has cut through garbage, particularly easily causing incised wound people in cutting rescue, survivor can be produced serious threat by the abradant jet of high energy.On the other hand, being difficult to determine depth of cut when cutting object currently with abradant jet, particularly when needing the cutting operation carrying out given depth, existing abradant jet technology is often difficult to be competent at.
Summary of the invention
For solving the problem existing for prior art, the invention provides a kind of regulate and control the method for abradant jet and device.
The technical solution adopted in the present invention is: a kind of regulate and control the method for abradant jet and device, including water jet generation systems, abrasive mixed assembly system, monitor control system.Described water jet generation systems mainly includes water pump, filter, relief valve, water tank, high-pressure water pipe, Pressure gauge, relief valve, power supply, conductor wire.Described abrasive mixed assembly system mainly includes abrasive can, controllable stop valve, hybrid chamber, nozzle, choke valve.Described monitor control system mainly includes controller, uhf electromagnetic wave radar monitoring device, holding wire.Described uhf electromagnetic wave radar monitoring device is arranged on nozzle.Described uhf electromagnetic wave radar monitoring device sent electromagnetic wave every 0.02 second and carries out the detection of depth of cut.Described high-pressure water pipe is provided with relief valve.Described relief valve, power supply, controllable stop valve, controller and uhf electromagnetic wave radar monitoring device are connected with each other by holding wire.Relief valve, power supply, controllable stop valve can be controlled by described controller.
When carrying out orcible entry and rescuing people's operation, described water jet generation systems and abrasive mixed assembly system produce abradant jet and carry out orcible entry operation, the depth of cut of abradant jet monitored in real time by uhf electromagnetic wave radar monitoring device simultaneously, and by holding wire, depth of cut data message and radar appearance intensity data information are transferred to controller in real time.Controller processes depth of cut data message and the radar appearance intensity data information of uhf electromagnetic wave radar monitoring device conveying in real time.When adjacent moment depth of cut data message is uprushed, namely when the growth of depth of cut generation staged and radar appearance intensity reduce by 70% and are above, the judgement that cut material body is cut through made by controller, is simultaneously emitted by instruction and makes controllable stop valve close in time, cuts off the supply of abrasive material；And open relief valve, lay down hydraulic pressure；Simultaneously close off power supply.
When carrying out cutting operation, if needing to carry out given depth of cut operation, inputting the depth data to cut first in the controller, then water jet generation systems and abrasive mixed assembly system generation abradant jet carry out cutting operation.The depth of cut of abradant jet monitored in real time by uhf electromagnetic wave radar monitoring device, and by holding wire, depth of cut data message is transferred to controller in real time.Controller processes the depth of cut data message of uhf electromagnetic wave radar monitoring device conveying in real time.When depth of cut data reach the depth of cut specified, controller sends instruction makes controllable stop valve close in time, cuts off the supply of abrasive material；And open relief valve, lay down hydraulic pressure；Simultaneously close off power supply.When carrying out simple cutting operation, namely not the given cut degree of depth time, differ primarily in that monitor control system can work when it is with given cut deep operation, concrete steps repeat no more.
When carrying out extinguishing operation, controller sends instruction makes controllable stop valve close, and cuts off the supply of abrasive material.Water jet generation systems and abrasive mixed assembly system produce pure water jets and carry out extinguishing operation.After fire extinguishing completes, open relief valve, lay down hydraulic pressure；Simultaneously close off power supply.
As preferably, described high-pressure water pipe being provided with relief valve, choke valve, Pressure gauge and filter.
