Embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the dredger of the present invention, as shown in Figure 1 to Figure 3, including hull 1, hull 1 use hermetically sealed side
Cabin floating drum, is linked together by steel member, has Ride Control System and propulsion system on hull 1.Frame is built on hull 1
Workbench, is provided with high-pressure hydraulic pump 2, sewage pump 3, generating set on platform（Not shown in figure）, centrifuge 7, storage spoil hopper 6 and
High-pressure jet formula underwater desilting device 4.The front end of hull 1 is provided with the dragging for pulling high-pressure jet formula underwater desilting device 4
Mechanism 5, pulls and high-pressure hydraulic pump 2 is provided with rear side of mechanism 5, and the water source of the high-pressure hydraulic pump 2 in the present embodiment is derived from river
River water, the rear side of high-pressure hydraulic pump 2 are provided with sewage pump 3, and the rear end of sewage pump 3 is connected with centrifuge 7, and centrifuge 7 takes out sewage pump 3
The sewage to come up carries out mud-water separation, and water is directly discharged into river, and mud enters storage spoil hopper 6, high-pressure jet formula underwater desilting dress
4 are put to be connected with high-pressure hydraulic pump 2 and sewage pump 3.High-pressure jet formula underwater desilting device 4 includes housing, and housing uses stainless steel
Form, the purpose so designed in order to increase the weight of housing so that housing the bottom tightly fasten.The present embodiment
In housing be bottom opening, the bionical tortoise shell construction of closed upper part, high-pressure jet formula underwater desilting device 4 is walked under water
The appearance design of Shi Caiyong tortoise shell constructions can be avoided when running into barrier to be passed through and the appearance design of tortoise shell construction has
It is close to the bottom beneficial to high-pressure jet formula underwater desilting device 4.Housing forward end has the dragging orifice plate 43 being connected with pulling mechanism 5,
Orifice plate 43 is pulled to be obliquely installed in the upper end of housing.Dragging mechanism in the present embodiment uses bowden cable and loop chain with pulling orifice plate
The advantages of common towing, so design is that wirerope and loop chain are spare each other, and when accident occurs in any one, another also can be by water
Lower equipment is recovered on dredger in time.Case top has the dirt removal first 41 that be connected with high-pressure hydraulic pump 2, dirt removal first 41 away from
Enclosure interior is goed deep into one end that high-pressure hydraulic pump 2 connects, and dirt removal first 41 is vertically arranged, and the benefit so designed is that dirt removal first 41 can be straight
The underwater dirt of impact is connect, there is stronger impact force.Dirt removal first 41 in the present embodiment has the effect of Multi-angle impact, can be right
Water-bed dirt, which implements comprehensive impact, to be ensured to rush dirt.In order to increase dirt removal effect, dirt removal first 41 sets three, exists certainly
Other Arbitrary Digits are alternatively in other embodiment, and first 41 parallel interval of three dirt removals arranges and positioned at the front end of housing.Shell
Rear side at the top of body in dirt removal first 41 deviates from what is be connected with sewage pump 3 with the sewage absorpting heat 42 being connected with sewage pump 3, sewage absorpting heat 42
It is in flare openings that enclosure interior and end are goed deep into one end, and sewage absorpting heat 42 is vertically arranged, and the purpose so designed is to incite somebody to action
The dirt that dirt removal first 41 has been rushed sucks to greatest extent.Sewage absorpting heat 42 in the present embodiment is also three, is implemented certainly at other
Any other number is alternatively in example, and three 42 parallel intervals of sewage absorpting heat arrange and positioned at the rear end of housing.The present embodiment
In dirt removal first 41 caliber be less than sewage absorpting heat 42 caliber, the purpose so designed be in order to make impact water be less than suction out water
Amount, avoid causes housing to be tumbled because amount of flush water is more than water absorption, so as to contribute to housing to consolidate under water.
In order to increase obstacle climbing ability when high-pressure jet formula underwater desilting device 4 is walked under water, housing bottom is provided with
Inclined plate 44, inclined plate 44 are tilted to the front end of housing, and inclined plate 44 is located at four end all around of housing, when high-pressure jet formula is clear under water
Silt device 4 can be avoided when all around four sides run into barrier under water.Hull outside is provided with rubber curtain 45,
When water-bed rugged pebble layer is crossed under working status, when housing cannot closely be buckled in the bottom, rubber curtain can
Play sealing function, timely sealing slurry, it is ensured that will not polluted-water.Underwater microorganism is sucked during dredging in order to prevent
（Such as fish shrimp crab）, housing bottom is also equipped with protection network, and protection network can also be replaced by flase floor in other embodiments.This implementation
High-pressure jet formula underwater desilting device 4 in example is provided with underwater level meter, and underwater level meter is based on Internet of Things automated control
With detection technique, the thickness of water bottom mud is detected in real time, underwater level meter is by calculating according to different silt depths
Machine automatically controls that the speed of travel, dirt removal be first 41,42 pressure of sewage absorpting heat provides possibility.High-pressure jet formula underwater desilting device 4 is also
Remote monitor is installed, remote monitor is based on Internet of Things and 4G mechanicss of communication, can supervise high-pressure jet formula water by video
The real-time status that lower Accrete clearing device 4 is run simultaneously can remote monitoring, supervision and offer technical support.High injection in the present embodiment
Streaming underwater desilting device also installs Beidou navigation additional, realizes positioning and remote weighing.Managed based on network communications technology using backstage
Software is managed, remote control is carried out to Ride Control System, realizes that dredger is unmanned, intelligent work.
The dredger of the present invention drives to working region in use, dredger pulls high-pressure jet formula underwater desilting device 4,
High-pressure jet formula underwater desilting device 4 is immersed to the bottom, determines equipment posture and in good condition.Start boat-carrying generating set to set
It is standby that electric power is provided, start boat-carrying centrifuge 7, high-pressure hydraulic pump 2, sewage pump 3 successively.The high pressure water flow that high-pressure hydraulic pump 2 produces is through height
Dirt removal first 41 in injection streaming underwater desilting device 4 sprays, and stirs mud sludge, forms mud, high-pressure jet formula is clear under water
Sewage in silt device 4 is taken away through sewage absorpting heat 42 by sewage pump 3, is sent into boat-carrying centrifuge 7, sewage is carried out muddy water by centrifuge 7
Separation, water are directly discharged into river, and sludge enters storage spoil hopper 6, complete the dredging work of the working region.Dredger pulls high injection
