In the present embodiment, buffer air bag 13 is set to elliptic conic shape with the integrally-built outline that outer tube 1 forms, reducing this pipe dredging device resistance when front advancing in drainage pipeline, when being more conducive to this pipe dredging device efficient operation, can also strengthen the stability of whole pipe dredging device, thereby make pipe dredging device being difficult for breakking away in traveling process forward, contribute to increase work efficiency.During concrete enforcement, the outline of described outer tube 1 first half is elliptic conic shape, and left surface and the right flank of described outer tube 1 latter half are elliptical arc surface, and upper surface and lower surface are horizontal plane; Described buffer air bag 13 outlines be shaped as elliptic conic shape.The shape of spool 8 is set to truncated cone-shaped, and the shape of valve opening 7 inner surfaces is set to the taper shape matched with described spool 8 shapes, makes water flow control valve door mechanism to close ground more tight, and difficult generation is leaked.
The process that adopts the utility model pipe dredging device to carry out pipe dredging is: at first, connecting one section flexible pipe on described inner tube 2 by flange 16 can be the corrosion resistance rubber tube, make flexible pipe and inner tube 2 tube walls keep tight seamless link state, and by lower well, this pipe dredging device level is inserted in drainage pipeline, by ground high-pressure hydraulic pump, by high-velocity flow, by flexible pipe, be transported in the inner tube 2 of this pipe dredging device; During current acceleration mechanism in high-velocity flow is flowed through inner tube 2, according to the principle of Bernoulli equation, high speed water fails to be convened for lack of a quorum and further accelerates and arrive rapidly water flow control valve door mechanism place, and the discharge after this current acceleration mechanism accelerates is about 10m
3/ h～15m
3/ h, because water velocity has little time more greatly to discharge, cause spool 8 under the impact of current suddenly shutoff in valve opening 7, be that water flow control valve door mechanism closes, produced water hammer effect one time, the energy produced by water hammer effect has passed to whole pipe dredging device by valve seat 6, drives whole pipe dredging device and advances forward, and pipeline sludge is produced to an extruding fluffing action; After water hammer effect finishes, spool 8 is under the elastic force effect of the first spring 11, eject from valve opening 7, bounce back into the front initial position of water hammer effect, current flow out from valve opening 7, via shower nozzle 3 and Venturi tube 4, current are accelerated again, by jet nozzle 5, by the water ejection, further impact and break up mud, thereby advance forward and the effect of water flow jet is issued to the effect of removing mud at pipe dredging device, make mud flow out and enter in next gully by blow-off line; When pipe dredging device advances to forward next gully position, pipe dredging device is taken out from this gully, pipe dredging device is cleaned and safeguards, thereby carry out again the desilting work of next segment pipe.Due to the special structure of Venturi tube 4, make current section's acceleration within it, thereby reached the purpose of strengthening the water flow jet effect, water flow impact pressure is large, better desilting.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification of above embodiment being done according to the utility model technical spirit, change and equivalent structure change, and all still belong in the protection domain of technical solutions of the utility model.
