Description
Technical field
The utility model is to be related to a kind of hand-held desilting equipment, concretely relates to one kind and is primarily adapted for use in large scale
The hand-held desilting equipment of box culvert.
Background technology
Sewage reduces from flow velocity after the big soft Box-shaped Drainage Culvert of Box-shaped Drainage Culvert inflow of the gradient, the silt carried in sewage
It is easily deposited with suspended solid in the box culvert that the gradient is small, size is big；In addition, the discharge of sewage and stream that box culvert is received in dry season
Speed is much smaller than rainy season value so that rainy season can be deposited by bulky grain suspended matter that sewage is taken away at dry season；At the same time,
Possible physics, chemical reaction can also cause curing, being hardened for sediment between deposit, further deepen the thickness of siltation.
All there is different degrees of siltation problem in the large scale box culvert in lot of domestic and foreign city at present, if siltation pipeline is cleared up not in time
It will influence the normal operation in residents ' health and city.
Domestic and international application mainly has high-pressure water jet dredging method, winch dredging method, Shui Chong in the dredging method of box culvert at present
Brush dredging method and retain rinse door dredging the methods of.These methods are substantially to be designed for small size box culvert, some technologies
Be not suitable for applying in large scale box culvert, there are operating cost is excessively high, dredging ability when large scale box culvert is run for some technologies
It is insufficient, do not adapt to there are secondary pollution and the limitations such as MODEL OVER COMPLEX TOPOGRAPHY.With vehicular high pressure water currently more prevailing
For Jet Dredging method, due to the high-pressure water jet provisioned in it, size is less than normal for large scale box culvert section, is produced
Raw high-pressure water jet cannot stir the deposit in entire section；Its cost and operating cost are very high, it is difficult in common row
Waterpipe is gone along with sb. to guard him in enterprise and is applied；It needs to consume a large amount of clean waters during dredging, itself does not simultaneously meet sustainable development
Theory, and impact generates waste water and may overflow or pour in down a chimney into branch drain from inspection shaft, be easy to cause secondary pollution.At present
The box culvert dredging of China urban, which is also to rely on, manually removes, such as artificial clear using spade and the progress of rubber raft tool
It becomes silted up, efficiency is very low.

Further, the side of idler wheel is connected by axis with dredging gear, and opposite side and dredging baffle side are fixed, idler wheel
Main body is made of stainless steel, and idler wheel surrounding package rubber, main function moves equipment and protection dredging for convenience of staff
Gear.
Further, dredging baffle is made of the stainless steel that three bread are wrapped up in, and for fixing dredging gear, idler wheel, connection are held
Hand, while mud is prevented to be splashed to staff upwards.
Further, water service hose is made of rubber, primarily serves the effect of water.
Its basic principle makes it for high pressure water flow is transported to dredging gear by high pressure cleaning pump, and impacts dredging gear
Quick rotation stirs mud by atwirl gear and the high-velocity flow to splash, mud is broken up, is washed away, so as to play
The effect of dredging.
Compared with prior art, the beneficial effects of the utility model are：
1. can not only remove loose mud, equally there is preferable dredging effect for hardened mud.
2. on the basis of conventional high-tension water-jet dredging, the stirring action of dredging gear is increased, improves the effect of dredging
Rate.
3. staff can very easily grasp handle and carry out dredging, convenient hand-held, and without using traditional
The equipment such as spade mitigate the burden of staff significantly.
4. can not only clean the mud of box culvert bottom, the mud of box culvert side can also be cleaned.
5. for the utility model in front end not using electric power, risk of not getting an electric shock in dredging is safer.
6. the structure of utility model is relatively easy, of low cost, be conducive to large-scale promotion use.
