Abstract
The utility model discloses a riverbed desilting device which comprises a diversion pipe which is arranged in the direction of an upstream face, wherein a water outlet of the diversion pipe is communicated with a water delivery pipe of which the diameter gradually decreases, and a water outlet of the water delivery pipe is provided with a locating device. The riverbed desilting device is characterized in that a kinetic energy difference of a surface layer water current and a bottom layer water current of a river is utilized to disturb silt at the river bottom, the surface layer water current with large kinetic energy is delivered to the river bottom through the diversion pipe and the water delivery pipe which is communicated with the diversion pipe and gradually decreases in diameter, silt silted at the river bottom is disturbed, so that silting of the silt at the riverbed is reduced. The riverbed desilting device is simple in structure, low in manufacturing cost and capable of being used repeatedly, does not need motive power, has no influence on a watercourse and environment of two banks, and can be widely applied to dredging engineering of the watercourse.
Description
Technical field
The utility model relates to the hydraulic engineering field, especially relates to a kind of river dredging device.
Background technology
The silt alluvial often causes the riverbed water level to be raised behind the riverbed, and the river course flood section dwindles, and brings flood control safety hidden danger.The channel aggradation problem that how to solve heavily silt-carrying river is the person's that perplexs the water conservancy working for a long time a a difficult problem.The main mode of river dredging is the dredge boat desilting at present, and the dredge boat type comprises cutter suntion dredger, dipper dredger and the grab boat etc. of self-propulsion type trailing suction hopper dredger, band dredging tube line.Adopt dredge boat to remove riverbed sludge, not only complex structure, make the maintenance cost costliness, and sludge treatment also can take a large amount of spaces on the bank, is difficult to large-scale promotion application.
Summary of the invention
It is a kind of simple in structure, cheap that the utility model purpose is to provide, and can reuse, and need not power, and river course and two sides environment are not had influence, can be widely used in the river dredging device of training of river channel engineering.
For achieving the above object, the utility model can be taked following technical proposals:
River dredging device described in the utility model, it comprises the mozzle that is provided with along the upstream face direction, and the delivery port of described mozzle is communicated with the water-supply-pipe of tapered diameter, and the delivery port of described water-supply-pipe is provided with positioner.
Described water-supply-pipe is the plastic film capicitor of automatically retractable.
The hollow out formula cone that described positioner is welded by connecting rod for two-layer circular metal framework up and down.
Described mozzle is the horn mouth structure, uniformly on mozzle water inlet outer wall is provided with a plurality of pin holes.
The utility model advantage is to utilize the kinetic energy difference of top layer, river current and bottom current to come the disturbance bed-silt, water-supply-pipe by mozzle and the tapered diameter that is communicated with it, the top layer current that will have big kinetic energy are delivered to the river bed, disturbance river bed silt alleviates riverbed silt alluvial.Of the present utility model simple in structure, cheap, can reuse, need not power, river course and two sides environment there are not influence, can be widely used in the training of river channel engineering.

The specific embodiment
Shown in Fig. 1,2,3,4, river dredging device described in the utility model, it comprises the mozzle 1 that is provided with along the upstream face direction, the delivery port of described mozzle 1 is communicated with the water-supply-pipe 2 of tapered diameter, described water-supply-pipe 2 from mozzle 1 linkage section to the bottom delivery port, caliber dwindles gradually, discharge area reduces gradually, water velocity strengthens gradually, has bigger kinetic energy when making current flow to delivery port, has aggravated current washing away bed-silt; Described water-supply-pipe 2 is the plastic film capicitor of automatically retractable, and length can be flexible automatically with the riverbed depth according to residing position in the river course, regulates the water-supply-pipe flexibility; Delivery port at water-supply-pipe 2 is provided with positioner, the hollow out formula cone that described positioner is welded by connecting rod 4 for two-layer circular metal framework 3 up and down, fixing delivery port position, assurance delivery port stability, and its frame construction does not influence water yield, and the silt that can not cause disturbance is obstructed at delivery port and causes the secondary alluvial; Described mozzle 1 is the horn mouth structure, is positioned at outer wall upper edge level and vertical direction is symmetrically arranged with four pin holes 5 at the water inlet of mozzle 1.
During use, with fixed cylinder 6,7 are individually fixed in the two sides, river course, by fixed handle 8,9 with protecting wire net 10 and fixed cylinder 6,7 connect, described protecting wire net 10 is made for polyethylene or nylon material, at river major trough and point bar place according to actual desilting needs, by the bayonet lock that is used with pin hole 5 with one or more river dredging devices along the river road upstream face direction be fixed on the protecting wire net 10, because protecting wire net 10 is connected with Accrete clearing device, can cushion than the impact of high speed water flow Accrete clearing device, reduce the influence of Accrete clearing device, reduce the flow energy loss flow-shape.And corresponding mozzle 1 place connects foam ball float 12 by nylon rope 11 on protecting wire net 10, can indicate the position of Accrete clearing device in the river.Water-supply-pipe 2 by mozzle 1 and the tapered diameter that is communicated with it, the top layer current that will have big kinetic energy are delivered to the river bed, disturbance river bed silt, alleviate riverbed silt alluvial, reach the purpose of river dredging, fixed cylinder 6,7 can be moved to the other places recycling with Accrete clearing device after place desilting finishes.Of the present utility model simple in structure, cheap, can reuse, need not power, river course and two sides environment there are not influence, can be widely used in the training of river channel engineering.
