Description

Underwater dredging device

Technical Field

The utility model relates to a power equipment is located the bank, and agitator, inlet tube can be at the storehouse face underwater desilting device that removes under water.

Background

In actual construction, do not possess drainage condition or drainage cost too high construction storehouse face, need carry out drainage and desilting when carrying out the storehouse face clearance, adopt traditional clearance mode, adopt drainage facility to take out water earlier, then carry out silt and fine sand clearance, and need many times repeated flushing and suction clearance, construction cost is high, inefficiency, process are loaded down with trivial details, and the manual work drops into greatly.

Disclosure of Invention

The utility model aims at providing a simple manufacture, simple to operate, safe and reliable, but reuse's a desilting device under water.

The purpose of the utility model is realized like this:

an underwater dredging device, a bottom plate of a floating pontoon 1 is respectively reserved with a 1 st hole 9 and a 2 nd hole 10 according to the pipe diameters of an air supply pipe 3 and a water inlet pipe 6, the hole diameter of the reserved hole is 10mm larger than the pipe diameter, a ship body is coated with an anticorrosive paint layer, an air compressor 2, a slurry pump and a water outlet pipe thereof are positioned on the bank, the air supply pipe 3 and the water inlet pipe 6 which are positioned above the floating pontoon 1 adopt flexible pipes, the air supply pipe and the water inlet pipe which are positioned below the floating pontoon are respectively adopted with a 1 st rigid pipe and a 2 nd rigid pipe, the 1 st rigid pipe and the 2 nd rigid pipe respectively penetrate through the 1 st hole 9 and the 2 nd hole 10 on the floating pontoon 1, one end of the air supply pipe 3 adopts a flexible sleeve to be connected with an outlet of the air compressor 2, the other end of the air supply pipe is connected with the 1 st rigid pipe, an underwater stirrer 4 is connected with the 1 st rigid pipe, the slurry pump 5 is respectively connected with one end of the water inlet pipe 6 and the water outlet pipe 7, the other end of the water inlet pipe 6 is connected with the 2 nd rigid pipe, a chain block positioned on the floating pontoon is used for adjusting the 1 st hole 10, 2 rigid pipe, one end of cable 8 is connected to vessel 1, the other end is located on shore for towing vessel 1 to move on the water surface.

The air compressor 2, the air supply pipe 3 and the stirrer 4 form a set of stirring system, and underwater deposited silt and fine sand are suspended in water through stirring. The mud pump 5, the water inlet pipe 6 and the water outlet pipe 7 form a set of water pumping system, and the mud and the fine sand suspended in the water are pumped out together with the water.

Air supply pipe 3, inlet tube 6 are fixed on pontoon 1, and one end is close to the siltation body, and the other end is connected air compressor machine 2, slush pump 5, pull pontoon 1 through hawser 8 and move on the surface of water, can remove the clearance, steerable clearance scope.

The air supply pipe 3, the water inlet pipe 6 and the water outlet pipe 7 above the pontoon 1 are all flexible pipes, so that the installation is convenient and the movement of the pontoon is convenient; air supply pipe 3 below the pontoon and water inlet pipe 6 adopt rigid pipes, so that stirrer 4 is convenient to fix, and the phenomenon that the air supply pipe is out of control due to overlarge power when stirrer 4 operates is avoided, and the equipment operates stably.

When the underwater dredging device operates, the device is hoisted to the water surface by adopting hoisting equipment, the air compressor 2, the stirrer 4 and the mud pump 5 are opened to clean underwater silt and fine sand, and the device is hoisted to the shore for storage after the cleaning is finished, is cleaned and maintained in time, cleans surface stains, and can be repeatedly used.

The utility model discloses silt and fine sand under water are guaranteed quick effectual clearance to the desilting device under water, the utility model discloses simple manufacture, simple to operate, safe and reliable can be used to other positions after dismantling, reuse many times to greatly increased has enough to meet the need the use number of times and has prolonged life, and simple structure, convenient operation, effect are showing, material source is wide, the construction is simple swift, according to the operating mode characteristics of difference, only need adjust air feed pipe, intake pipe length and size, can extensively be used for the desilting construction under water.
