Description
Technical field
The utility model relates to the training of river channel technical field, especially a kind of Accrete clearing device that is used for training of river channel mud.
Background technology
Lake, China dense waterway net region river is numerous, water system is flourishing, but the river channel sedimentation problem becomes increasingly conspicuous.The blocked up river course effective depth that makes of river channel sedimentation shoals, water body capacity and irrigation and drainage ability drop, and the water body endogenous pollution increases the weight of, and water ecological environment worsens, and has weakened overall productivity in agriculture, has influenced the people's productive life.Dredging is the most effective engineering measure of rural area water resource, aquatic attitude and water environment protection.
Both at home and abroad existing little channel cleanout mud technical pattern has three kinds, and the one, water in the river course is drained with water pump in the back of constructing a dam, and with slush pump mud is extracted into the bank precipitation, but influence navigation or downstream water supply during desilting, the mud that hardens is difficult for extracting; The 2nd, mud in the river course is dug out in utilization grab excavator operation on river levee, stacks on the spot or transports with car and boat, but limited by river course and river levee width, is difficult for operation; The 3rd, with dredger desilting under water, characteristics are that complete machine is extracted into the bank while walk with mud and precipitates in water, can submersible, but wayward, the facility price is higher, difficult after operation is finished.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of simple in structure, integrated silt loosening and sucking device for removing silt that cost is low is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of integrated silt loosening and sucking device for removing silt, comprise high-pressure intake pipe, hydraulic spray, mud suction nozzle cover, mud outflow tube road, described mud suction nozzle cover is connected with an end in mud outflow tube road, described high-pressure intake pipe comprises first delivery port and second delivery port, in described mud outflow tube road, be provided with a water under high pressure runner, the import of this water under high pressure runner is connected with second delivery port, the outlet of water under high pressure runner is communicated with the inner chamber in mud outflow tube road and is consistent with the Way out in mud outflow tube road, described hydraulic spray is arranged on the described mud suction nozzle cover, and its water inlet is connected with first delivery port of high-pressure intake pipe.
Described water under high pressure runner is the annular water flow road, and the delivery port in annular water flow road is taper.
Between first delivery port of described high-pressure intake pipe and hydraulic spray, be provided with first water pipe, on described first water pipe, also be provided with a hydraulic pressure control valve.
Described hydraulic spray is 3, and is distributed on the same circle of mud suction nozzle cover.
The extended line of described 3 hydraulic spray spout directions meets at a bit, and intersection point is on the axis of described mud suction nozzle cover.
The negative pressure control valve of one adjusting nozzle diameter also is set between mud end and the water under high pressure runner exit in advancing of described mud outflow tube road.
The utility model integrated silt loosening and sucking device for removing silt, comprise one road high-pressure intake pipe, one road mud outflow tube, the water route of high-pressure water pipe is divided into two-way, one tunnel the loosening mud that hardens of 3 aperture jet water courses on the suction nozzle cover, one the tunnel oppositely flows out from the mud outflow tube through the water under high pressure runner, the current of high pressure are after the water under high pressure runner flows out from the mud outflow tube, rear end in the outlet of the water under high pressure of mud outflow tube forms a negative pressure, this just is in a pressure reduction between the outside of mud suction nozzle cover and mud outflow tube, mud is under the effect of this pressure reduction, flow out by auto-pumping and from outflow tube, saved pump housing extraction is set on the mud outflow tube.
Compared with prior art, the beneficial effects of the utility model are:
(1) the product reasonable integral structure is brief, has functions such as modular unit combination, and is in light weight, is convenient to carrying, movement-less part, and non-maintaining, specifications and characteristics meets the dredging standard;
(2) structure design uniqueness is regulated the best jet flow amount of inhaling according to the mud characteristic;
(3) it is unobstructed to have a drainage, is difficult for stopping up the advantage of tube chamber.
(4) easy operating by one man operation, is stood on the buoyancy aid by a people in the little river of deep water and operates in shallow water;
(5) safety, environmental protection and cost economy, the acceptable price of end user;
(6) be easy to produce, material and production are based on " standard " machine shop.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As Fig. 1, shown in Figure 2, the utility model integrated silt loosening and sucking device for removing silt is by high-pressure intake pipe 1, hydraulic spray 4, mud suction nozzle cover 3, mud outflow tube road 2, negative pressure control valve 5, high-pressure intake pipe 1 has two outlets, an outlet 11 is connected with hydraulic spray 4 on the mud suction nozzle cover 3, be used to spray the loosening mud that hardens of water under high pressure, the interior water under high pressure runner 21 in another outlet 12 and mud outflow tube road 2 is connected, the outlet of water under high pressure runner 21 and mud to go out flow path direction consistent, when water under high pressure when water under high pressure runner reverse flow goes out, can form the chamber 22 of a negative pressure in the rear end of outlet, referring to Fig. 4, utilize this negative pressure, the mixture that becomes flexible with mud and water can be extracted out from mud outflow tube road.In another outlet 12, the control valve 13 that is used to regulate hydraulic pressure is installed, as shown in Figure 2.
By from foremost High-Pressure Water, divide two-way to enter high-pressure intake pipe, one the tunnel enters mud suction nozzle cover inner chamber, the fluid that is formed by inner chamber becomes flexible the mud that hardens by 3 aperture jet water courses on the suction nozzle cover, cause mobile after utilizing kinetic energy to make liquid and deposit mixes, because the Incoercibility of ideal liquid, so mud directly flows to mud outflow tube road; Another road High-Pressure Water enters mud outflow tube road by the negative pressure control valve, produces the continuous sucking effect, is used for slurry conveyed.
