Abstract

The utility model relates to a dredging boat, which is a tool used for dredging river channels. A boat body is provided with an engine, a screw propeller, an object hanging device and a hydraulic pump which drives a hydraulic oil cylinder to move; the left and the right sides of the boat body are respectively fixedly provided with a lifting post, and the upper end, the middle part and the lower end of each lifting post are respectively hinged with the hydraulic oil cylinder, an upper lifting rod and a water separating plate frame; the lower end of the hydraulic oil cylinder is hinged with the middle part of the upper lifting rod; both ends of a lower lifting rod are respectively hinged with the upper lifting rod and a water separating side which is hinged with the water separating plate frame; a vibrating rod and an object blocking net frame are fixed on the water separating plate frame, the object blocking net frame is connected with a transverse plate via ropes and a vibrating motor and a hoister are fixed on the transverse plate. When the utility model works, the water separating plate frame can automatically fall to insert the river bottom to initiate water flow to generate large potential energy, and the purpose of river channel dredging can be realized by utilizing water force; the utility model has the advantages of convenience, labor saving and work efficiency enhancement.

Description

Dredge ship

Technical field the utility model relates to river course mediation technology, promptly a kind of instrument that is used to dredge the riverbed.

The many rivers of background technology, the Yellow River as China, wash away about 1,600,000,000 tons of quantity of sand and mud every year, because sediment charge is big in the river, the a large amount of depositions of silt often cause one, 20 meter more than above ground level of riverbed, become " aboveground river " very easily cause breach a dyke break down, the serious consequence of river diversion, bring serious threat and loss for people across the Straits' lives and properties, for this reason, need frequent dredging river.Usually the method in cleaning river course has shell pump method, ship to drag for micromicrofarad etc., and all there is big, the ineffective problem of labour intensity in this several method; Other has, and a kind of method-with the water storage of the reservoir method with the high pressure ejection, so as to reaching the purpose of removing the channel fill deposit thing, obviously this method can only be washed away river course nearby, dam, river,, can't solve mediation problem away from the river course on dam, river.

Utility model content the purpose of this utility model is, designs a kind of new-type instrument that mainly utilizes self strength cleaning riverbed of current.

The utility model is achieved in that driving engine, spiral propeller being housed, hanging on the hull commonly used of thing device, sets up hydraulic efficiency pressure system; On the side of a ship of hull both sides, be fixed with lifting column, the upper end of this lifting column, middle part, lower end link with hydraulic ram upper end, last lifting arm upper end, water back-turning plate frame respectively; Hydraulic ram lower end and the hinge joint of last lifting arm middle part; Last lifting arm lower end and following lifting arm upper end hinge; Following lifting arm lower end and the hinge joint of folding water group; Folding water group and the hinge joint of water back-turning plate frame.On the water back-turning plate frame, its rear portion is the plate face, and there are a plurality of water holes the front portion, and leading section is installed with ploughshare.Portion before the water back-turning plate frame of water hole is arranged, be fixed with vibrating head; Have that end flexibly connects under the water back-turning plate frame rear portion of water hole frame and the blocking net frame, end is connected with rigging on the blocking net frame, is fixed on the transverse slat of fore on the rigging, is fixed with the winch of vibrating motor and folding and unfolding vibrating head on the transverse slat.

During work, this ship is sailed to the place, river course that desire is dredged, fore and current are equidirectional, cast anchor.The primer fluid compressing cylinder inserts the water back-turning plate frame in the water by lifting arm.Water is gone out pit with bigger potential energy with the ship below under the guiding of the plate face of water back-turning plate frame.Meanwhile, be connected the also vertical expansion of blocking net frame, rigging between water back-turning plate frame and the fore transverse slat, vibrating head produces vibration under the effect of vibrating motor, and then drive water back-turning plate frame vibration, making ploughshare insert the riverbed also shakes hard riverbed broken, in the wings under the promotion of water, the silt in the place ahead is rolled, washed away thereupon.Because the water back-turning plate frame of tiltedly putting causes the potential energy of the water that penetrates water hole very big for the structure in " top hole down ", and is extremely strong to propelling thrust, the scouring force of the place ahead silt, rubble.If when running into the material that boulder etc. is difficult to wash away, can the water back-turning plate steelframe be risen back hull bottom by hydraulic ram, stone is emerged, with hanging the thing device it is taken away.

The utility model is changed routine and is adopted method artificial or that machinery is fished for channel deposits, but mainly by the potential energy of current, produce powerful scouring force, thereby reaches elimination or alleviate flood, and the control current are regained the purpose that water accounts for the soil.Save manpower and materials greatly, improved work efficiency.
