Abstract

The utility model discloses an efficient dredging boat that consists of a boat body, a water pump, a water pipe, a sand emitting squirt gun and a driving device. When the utility model is working, powerful water steam can force the deposited sediment to leave the river bed and to flow into the water with optimal angle and pressure. The sediment is brought by water steam and will flow away with the water steam in certain condition, which is a natural principle of the movement of sand and water. Such method greatly reduces the engineering cost, sends the sands toward the sea and completely solves the problem of discarding sediment.

Description

Efficient dredger

The utility model belongs to the boats and ships class, particularly be a kind of working ship of removing river channel sedimentation silt.

Existing working ship is as cutter suction dredger; Towards Suction Dredger; Strand is towards compound dredger; Though each is different for their structure, they have a common characteristic: all be the shoal materials of river bed to be dug deliver on the bank.For the engineering of digging husky spoir enormous amount, deposit spoir and abandon and husky just become problem, for example to reduce the riverbed engineering be exactly like this to the removing silt of the Yellow River.A kind ofly can be placed in desilting working ship in the deep-sea, just become people's hope abandoning sand.

The purpose of this utility model just provides a kind of desilting working ship that can be sent to channel aggradation silt the sea.

The purpose of this utility model is achieved in that accompanying drawings is as follows:

A kind of desilting working ship, its design feature is: motive power machine and water pump are installed in hull 1, the water inlet 2 of its water pump is located at the below of fore, 2 delivery ports of water pump were located at the both sides of ship in 3 minutes near on the straight line of fore, what be connected with pump outlet 3 is 2 water pipes 4, what be connected with water pipe 4 other ends is to fix linkage 6 on the sand shot hydraulic giant group 5 from the sand shot hydraulic giant group 5 in motion tracking riverbed, and the other end of linkage 6 is located at pump outlet 3 places.

Deposit is under water carried by current, as long as conditions being possessed, these deposits necessarily can flow away with water again, and this is a kind of natural phenomena.Efficient dredger is a floating object waterborne, and its work can make the shoal materials riverbed that leaves successively sneak in the mobile water, becomes the most important condition that shoal materials moves again.

Accompanying drawing is the structural representation of efficient dredger.

Description of drawings and embodiment:

Among the figure, 1 is hull, and 2 is pump intake, and 3 is pump outlet, and 4 is water pipe, and 5 are sand shot hydraulic giant group, and 6 is linkage.

By accompanying drawing as can be known, channel aggradation silt is implemented the working media-water of impact, enter hull 1 by pump intake 2, come out from pump outlet 3 in the pressurization back, through water pipe 4, arrival can be adjusted the sand shot hydraulic giant group 5 of angle, and impacted to the riverbed with the angle of the best by the control of linkage 6.

If it is not enough that pump outlet 3 keeps clear of the length of fore or water pipe 4, sand shot hydraulic giant group 5 just is not easy to touch the riverbed, and can't work.So the position of pump outlet 3 should be located at the place near pump intake 2, the length of water pipe 4 should be between 0.5 to 1.5 captain, and the operating depth of the long more adaptation of water pipe 4 is just dark more.

By accompanying drawing as can be seen, asked an angle to working flow and horizontal plane that the riverbed impacts, the size of this angle will be determined according to the quality of removing thing, generally should fix on 20 degree between 80 degree, finishes by handle linkage 6 in the service depot.Can also adjust the direction of the current that impact to the riverbed by handling linkage 6, the realization boats and ships move forward or move backward.

Working condition of the present utility model is as follows:

Start the water pump that diesel engine drives in the hull 1, the river laggard oral siphon 4 that will pressurize, at this moment will be according to the quality situation that will remove mud, the pressure of water is adjusted to a suitable numerical value, generally in 0.5 kg/cm to 15 kg/cm scope, the water of these band pressure is implemented to impact to shoal materials from the sand shot hydraulic giant group 5 of following the tracks of the riverbed and (is realized that the method for following the tracks of the riverbed has a variety of, for example the simplyst be: utilize the deadweight of sand shot hydraulic giant group 5 just can realize), shoal materials is mixed, then with the current direction sea with the river that flows.Thereby finish the mission of desilting.Can handle the angle that linkage 6 is regulated directive riverbed current repeatedly in order to obtain optimum efficiency,, obtain till the most satisfied effect up to finding the soil property that is fit to here and the angle of current.

Advantage of the present utility model is mainly manifested in: with the engineering of existing similar identical horsepower Ship is compared, and efficient can improve greatly. The second, solved a difficult problem of throwing aside useless husky roach.
