Abstract
The utility model relates to a sand disturbing and sludge cleaning device for a river channel, which makes use of the water surface kinetic energy to disturb mud and sand on the river bottom. By making use of the difference between the water surface flow velocity and the river bottom velocity, the utility model increases the river bottom velocity, and enhances the scouring effect of the water flow to the river bed and the transportation ability of the water flow to the mud and sand. The utility model is used for the sludge cleanness of the deposited sludge in rivers and channels to solve the problems that the existing sludge cleaning device has complex structure and is inconvenient to operate underwater, the existing sludge cleaning device has poor practicability and is difficult to generalize and apply in the manufacture, and the existing sludge cleaning device has larger investment and is difficult to form construction scale, etc. The utility model is mainly composed of a water inlet funnel, a flow guiding funnel and a plasticity conduit pipe, wherein a water inlet of the water inlet funnel of the utility model faces to the water flow, and a water outlet is connected with the flow guiding funnel; the other end of the flow guiding funnel is connected with the conduit pipe, and a sand flushing opening of the tail end of the conduit pipe is pulled to the river bed. The utility model makes use of the self energy of the water flow of the river channel to clean out sludge without other energy consumption and pollution, can work all the time, can continuously perform function and can continuously perform effect.
Description
Affiliated technical field
The utility model relates to a kind of rivers river course that utilizes water surface kinetic energy destabilization river sediment Accrete clearing device of silt under water.
Background technology
The heavily silt-carrying river river channel sedimentation is the biggest problem of river regulation.Raise flood level after the channel aggradation, cause difficulty to flood control.Channel aggradation often causes that the river gesture is changeable, at any time flood protection works is caused danger.Riverbed, section, downstream part, the Yellow River exceeds the outer tens of rice of dike, once embankment bursts, really becomes " the water sky of the Yellow River comes up " concerning the outer occupants of dike.
River course desilting under water at present mainly contains: disturbance is dredged desilting and is dredged desilting.Wherein disturbance is dredged desilting and is mainly contained jet disturbing type, blast disturbance and other utensil disturbance.The desilting of dredging mainly contains jet drawing-in type, air-powered pump formula, pump cutter formula, long-armed strand suction formula (or bucket wheel) formula, deep water grab type, submersible type, submersible dredge pump drawing-in type etc.
Heavily silt-carrying river for example the Yellow River has several hundred million tons of silts to enter the river course every year, can reach more than 1,000,000,000 tons at most.By artificial mechanism silt is gone out clearly outside the river course, it only is " a drop in the ocean " to the quantity that channel deposits reduces, and it is the main method that solves the channel deposits problem that sediment is gone into the sea.The quantity of silt alluvial and the mission requirements desilting equipment of channel cleanout are simple in structure, cheap, and practicability and effectiveness forms scale easily.
Once there was multinomial river course to disturb the patent utensil of sand and desilting in the past, but also not having of on the most outstanding the Yellow River of Sedimentation Problems, promoting the use of.The major defect that exists: 1. complex structure, inconvenient subaqueous construction; 2. practicality is not strong, is difficult to apply aborning; 3. investment is bigger, is difficult to the formation scale.
Summary of the invention
The technical problems to be solved in the utility model: the utility model overcomes the defective of equipment existence in the past, provides a kind of river course of water surface flow energy disturbance river sediment that utilizes to disturb husky dredging device.
The technical scheme that its technical problem that solves the utility model adopts is:
Utilize the difference of water surface flow velocity and bed velocity that the river course is guided to the river bed near the bigger current of water surface flow velocity, increase bed velocity, strengthen current to the souring in riverbed and current to the defeated ability of moving of silt, reach the channel cleanout purpose.Realize this purpose by the utility model.
Core of the present utility model is the water guide system, is made of influent hopper, water conservancy diversion funnel and plasticity water-supply-pipe.More than three parts fuse, the water inlet of influent hopper is met to current, delivery port connects the water conservancy diversion funnel with flange, water conservancy diversion funnel other end plug-in type connects water-supply-pipe, outsidely tightens with ferrule, water-supply-pipe tail end sand surfing mouth drags in the riverbed.Above the water conservancy diversion funnel buoyancy tank is installed, is guaranteed that by buoyancy tank influent hopper places the nearly water surface.Flag is installed on the buoyancy tank, indicates the position of this device in the river course.On the riverbed of job position, place rake, the water guide system is linked to each other with rake, stop this device to drift about or slow down the speed of drift with current by wire rope.
The water inlet of influent hopper is a rectangle, and outlet has a plurality of, and the cross section is circle.Water conservancy diversion funnel and water-supply-pipe cross section are circular.Water-supply-pipe adopts plasticity better and the material of certain degree of hardness is arranged, and water-supply-pipe can form linear preferably naturally and keeps in touch the riverbed in the use.Rake is a tabular, and all there is spine top and bottom.
The beneficial effects of the utility model are: 1. utilize the streamflow self-energy to carry out channel cleanout, do not have other energy consumption; 2. transfer to the work that can always not stop behind the river course, play a role continuously, constantly tell on; 3. simple in structure, cheap, can form bigger scale with less investment, channel cleanout is produced bigger effect; 4. streamflow and two sides environment there is not any pollution effect.
Description of drawings
Fig. 1 is a structure side view of the present utility model.
Fig. 2 is a structure vertical view of the present utility model.
1. influent hoppers among the figure, 2. water conservancy diversion funnel, 3. buoyancy tank, 4. flag, 5. water-supply-pipe, 6. sand surfing mouth, 7. lacing grommet, 8. wire rope, 9. rake.
The specific embodiment
The utility model is made of influent hopper (1), water conservancy diversion funnel (2), buoyancy tank (3), flag (4), water-supply-pipe (5), sand surfing mouth (6), lacing grommet (7), wire rope (8), rake (9).Influent hopper (1), water conservancy diversion funnel (2) and water-supply-pipe (5) constitute core of the present utility model, claim the water guide system.During use, the water inlet of influent hopper (1) is met to current, and delivery port connects water conservancy diversion funnel (2) with flange, and water conservancy diversion funnel (2) other end plug-in type connects water-supply-pipe (5), and water-supply-pipe tail end sand surfing mouth (6) drags in the riverbed.Buoyancy tank (3) is installed above the water conservancy diversion funnel (2), is guaranteed that by buoyancy tank (3) influent hopper (1) places the nearly water surface.Buoyancy tank (3) is gone up flag (4) is installed, and indicates the position of this device in the river course.Water conservancy diversion funnel (2) bottom is welded with lacing grommet (7), rake (9) is placed on the riverbed of job position, and wire rope (8) one ends tie up on the lacing grommet (7), and an end ties up on the rake (9), the water guide system is linked to each other with rake, stop this device to drift about or slow down the speed of drift with current.Only need one group of the utility model is positioned in the river course that needs desilting, other is without any need for operation.
