Abstract

The utility model provides a river-way dredging device used for dredging a river-way. The device is constituted by that a wide-body, a ship whose rear segment forms a U-shaped split drags a barrel which can sink down to the river bed at the location of the U-shaped split. The centre shafts of the barrel whose periphery is provided with multiple flinty steel tooth rows are respectively installed on two rotating hinge wheels through two right and left connecting rods. On the occasion of dredging, the multiple ring pointed-wedge shaped flinty steel tooth rows of the barrel being pressed on the silt layer of the river bed, the solid silt layer is turned into loose, generating 'a sinuous flow' under the impact of the water flow, to be carried upward by the barrel and to be carried away by the strong water flow, and thereby, the goal of river-way dredging is achieved.

Description

A kind of Accrete clearing device of river course

Technical field

The utility model relates to and a kind of river course mud sand is silted up the device that carries out desilting.

Background technology

Because soil erosion, a lot of river courses of China all have a large amount of mud sand depositions to cause riverbed mud sand to silt up every year.As the Yellow River of China owing to annual have number to be deposited on the middle and lower reaches in river course, accumulate over a long period in hundred million tons mud sand, subterranean stream becomes canal on embankment, and also not efficiently at present, practicable Accrete clearing device and method.

Summary of the invention

The purpose of this utility model provides a kind of effect that can utilize river course self flow dynamic, and river course mud sand is silted up the device that carries out efficient desilting.

The channel cleanout device that the utility model is designed is with an expanded letter, and the hull that forms the U-shaped split at its back segment constitutes in cylinder that can be sunken to the riverbed down of U-shaped split place traction; Said cylinder comprises the cylinder of a band axis, at the spaced circular ring type steel ring of the fixing many rows of the periphery wall of cylinder, each is arranged has gusset to interconnect between the steel ring, fix the hard steel tooth of a circle glut shape in the periphery of each row's steel ring, thereby constitute the cylinder that its outer peripheral face has many row's hard steel teeth; The axis of said cylinder by about two connecting rods be installed in respectively on two rotatable hinge wheels of hull, said connecting rod can freely stretch from hinge wheel through transmission.

This channel cleanout device is when carrying out the channel cleanout operation, the cylinder that has the hard steel tooth of said hull traction is on the riverbed, under the promotion of water flow dynamic energy, roll across the riverbed, when cylinder rolls across the riverbed, glut shape hard steel tooth on the cylinder is pushed down into the mud layer of sand in the weight of cylinder self, the mud layer of sand passes through the extruding stirring on inclined-plane, the steel-tooth left and right sides and becomes loose mud sand, and generation " sinuous flow " under the impact of current, taken away by strong current upward by the cylinder band, therefore, cylinder rolls on the riverbed and goes over, the top layer, riverbed is promptly peeled a layer from, as long as enough the utility model equipment is arranged in river course each section operation, the mud sand on the riverbed will be taken out of outside the river mouth.Diameter of cylinder big more (diameter of cylinder can greater than 10 meters), water velocity is big more, and then the efficient of desilting is high more.

The effect of the traction ship in this channel cleanout device is that stable guiding traction cylinder advances, the traction ship generally is the operation of following current traction cylinder, when ship and cylinder will be returned the upstream, cylinder can be pulled away from the water surface, reducing ship resistance, can be by being arranged on the hull derricking gear cylinder is sling (rotating drivening rod by hinge wheel makes cylinder go up the water surface).If cylinder is bulky, for alleviating the cylinder own wt, the available aluminium alloys manufacturing of the cylindrical body part of cylinder, and can be made into sealed cylinder or make the structure of the segment space sealing of cylindrical shell.

The hard steel tooth of each the circle glut shape on the said cylinder can be assembled by the hard steel tooth assembly of polylith glut shape, to be assemblied on the steel ring easily.

The hard steel tooth of said glut shape can be fixed on outer rim on the steel ring with screw, changes when making things convenient for the medium hard steel odontotripsis.

The transmission mechanism that said connecting rod is freely stretched can adopt multiple mode, comprise adopt rack-and-pinion the transmission mechanism or the transmission mechanism of turbine worm etc.

In this channel cleanout device, the contact surface that is connected the position of said connecting rod and cylinder is sphere preferably, and this sphere can be bonded with the carbide alloy assembly unit.

The channel cleanout device that the utility model is designed, the cylinder that has many row's hard steel teeth with traction ship traction carries out dredging operation in the riverbed, by the cylinder steel-tooth stirring of riverbed mud layer of sand and the kinetic energy that makes full use of current are promoted, making the mud layer of sand in riverbed be stripped out the relief current takes away, reach the purpose of desilting, apparatus structure of the present utility model is reasonable, in carrying out channel cleanout, has practicality, efficient, energy-saving advantages.

The specific embodiment

Be described in further detail below in conjunction with the CONSTRUCTED SPECIFICATION of accompanying drawing the specific embodiment of the present utility model:

The overall structure of this channel cleanout device as shown in Figure 1 and Figure 2,2 for being used for the expanded letter hull of traction cylinder 1, the rear portion of this expanded letter hull forms the split hull of U-shaped, the axis 11 of cylinder 1 by about two connecting rods 3 be installed in respectively on two hinge wheels 4 of hull, rotation (adding pulling apparatus in addition) by hinge wheel 4 can lift cylinder to the water surface, and the transmission by the turbine worm fit structure between connecting rod 3 and the hinge wheel 4 can make connecting rod 3 freely stretch.The structure of cylinder 1 as shown in Figure 3, the center of this cylinder 1 is the cylinder 12 of the sealing of a band axis 11, at the spaced circular ring type steel ring 13 of the fixing many rows of the periphery wall of cylinder 12, each is arranged has gusset 15 to interconnect between the steel ring, said cylinder 12, circular ring type steel ring 13 and gusset 15 are the steel member, by being welded into an integral body.Fix the hard steel tooth 14 of a circle glut shape in the periphery of each row's steel ring 13, hard steel tooth 14 is assembled by the hard steel tooth assembly of polylith glut shape, the outer rim of said steel ring 13 is shaped on screw hole, every hard steel tooth assembly is fixed on the outer rim of steel ring 13 with screw 16, thereby constitutes the cylinder that its outer peripheral face has many row's hard steel teeth.When this channel cleanout device carried out dredging operation, cylinder 1 sank down into the riverbed face in U-shaped split place of hull, formed angle C (as shown in Figure 1) with the riverbed face, rolled at the riverbed face under the double action of the traction of hull and current then, carried out desilting work.
