Description

The deepwater dredging device

Technical field

The utility model relates to a kind of device of environmental protection technical field, particularly a kind of deepwater dredging device.

Background technology

Along with the continuous development of World Economics and the market demand that progressively enlarges, particularly the fast development of century world economy has been expanded new service field for the dredging industry, as mining, sea reclamation, seabeach maintenance, environmental protection regulation, seabed pipe trench, seadrome even archaeology field.Dredging plant has already obtained very big development, and at present commonly used have grab dredger, bucket dredger, cutter suction dredger, drag suction dredger and environmental dredging ship etc., but these legacy equipments exist wearing and tearing big; The maintenance cost height; Supporting inconvenience; Narrow application range; Depth of implements is restricted, and is powerless to deepwater dredging; Can pollute the riverbed during operation; The construction restricted problem such as bigger of marching into the arena.

Through the literature search of prior art is found: application is artificial: Japanese Moburon Design Office Co., Ltd., Chinese patent application number is: CN97199412.9, publication number is: CN1235652, name is called: dredging method and dredger.Its technical scheme is as follows: a kind of dredger, have: communicate with atmosphere and bury housing in water, be connected with this housing and the lower end is provided with the suction pipe of suction portion, to form the drainage pump of water-head between the discharge of the water in the described housing and the water surface in housing and the outside water surface, dismounting is arranged on the described suction pipe container at position midway freely; Adopt the dredging method of described dredger, with described drainage pump the water in the described housing is discharged the back and in housing, form the space, form water-head between the water surface in this housing and the outside water surface, the current that utilize this water-head to produce suck silt particle in the described container from described suction pipe.This device has the following disadvantages: though this technology can be used in mud, silt particle that dredging is deposited in reservoir, lakes and marhshes or bay, this apparatus structure is too complicated, energy consumption is high, maintenance cost is high, this apparatus structure is further improved have very big space.

Summary of the invention

The utility model provides a kind of deepwater dredging device at the deficiencies in the prior art.Simple in structure, saving energy, high efficiency, automaticity height, effect applied widely have been realized.

The utility model comprises gasholder, gas compressor, controller, compression pump, mud pipe, tracheae, force pipe, dredging tube, mud sucking cover, suction bucket, mud filter, mud valve.Connected mode is: gasholder joins by tracheae and gas compressor, and gas compressor joins with controller and mud filter respectively by tracheae, and wherein the tracheae that joins with mud filter is positioned at the upper end of mud filter, leads directly to into the inside of mud filter and is suspended on inside.Controller joins by tracheae and compression pump, compression pump joins by force pipe and mud sucking cover, mud sucking cover is inverted " funnel " shape, join by dredging tube and mud filter in the mud sucking cover, top at dredging tube is connected to mud valve, at the middle part of mud sucking cover the suction bucket is arranged, inhale bucket and also be inverted " funnel " shape, its " funnel " shape opening part diameter is little than mud sucking cover.Inhale bucket and join by dredging tube and mud filter, be connected to mud valve at the top of dredging tube, this mud valve is an one-way cock.Leave the space between mud sucking cover and the suction bucket.Mud filter is " cylindrical ", and there are some barriers inside, and barrier and mud filter inwall are " fan-shaped " shape and arrange.The top and the mud pipe of mud filter join.

This device running is as follows: controller control gas compressor is evacuated to the air in the mud filter in the gasholder, make the mud filter inner space form " vacuum " environment, controller controlled pressure pump injects mud sucking cover with air-water mixture from tracheae, inhaling formation air-water mixture space between bucket and the mud sucking cover, the ratio of air-water mixture can be regulated according to silt humidity and viscosity under water, takes out mud humidity by controller by dredging and carries out automatic mixing.Along with air-water mixture is pressed into the suction bucket by compression pump by the force pipe brute force, the pressure of inhaling between bucket and the mud sucking cover progressively increases, pressure makes the earth of inhaling between bucket and the mud sucking cover recessed, earth is squeezed, inhale the earth projection of bucket " funnel " shape opening part, earth is pressed into mud filter from dredging tube through mud valve, because mud filter inside is " vacuum " environment, therefore earth is under pressure and can enters mud filter easily, when mud filter closely overflows, controller control gas compressor pushes mud filter with the air in the gasholder by the tracheae brute force, mud filter is owing to be subjected to the gas pressure effect, and the mud mixture in its mud filter is pressed into mud pipe and discharges.

In order to keep the continous-stable of mudflow, gas compressor and compression pump are controlled automatically by controller, and mud filter is inner, and each barrier can carry out reciprocal operation owing to adopted the barrier setting, and its structure is applicable to deepwater dredging.

The utlity model has following advantage: simple in structure and energy-conservation, air distributor and pump main body are fixed together, shortened the length of the air hose that connects the two, reduced the energy loss of bringing when compressed air transmits in air hose; The mud gas in the jar becomes closed circulation with gasholder, and air compressor machine only plays the holding pump internal pressure when reaching the pump internal pressure, make energy utilization rate higher, more power saving and energy consumption.The design of mud sucking disk makes can effectively control the muddy water ratio in the dredging process, has improved operating efficiency, has reduced the cost of mud-water separation and purification of water quality.Cut apart by barrier in the single pump housing of the present utility model, not only played the effect of cutting from the pump housing, greatly improved the compressive resistance of the pump housing again, the restriction of pump barrel volume when having reduced deepwater dredging, saved manufacturing cost, the single pump housing is divided into some unit by some barriers with the pump housing, makes operation more simple, has overcome to make up the situation that the pump housing can't adapt to the underwater complex situation.The utility model also can be supporting automatic controller, further raise the efficiency when improving the dredging precision.
