Fig. 1 is the structural representation of embodiments of the invention；
Fig. 2 is the bucket wheel device structural representation of embodiments of the invention；
Fig. 3 is the structural representation of the middle standing pillar of embodiments of the invention；
Fig. 4 is another structural representation of the middle standing pillar of embodiments of the invention.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention done concrete explaination.
The semi-submersible dredget of embodiments of the invention, preferably cutter suction dredger or bucket-wheel suction dredger, enter
One step is preferably cutter suction dredger.Semi-submersible type cutter suction dredger as shown in Figure 1, including be sequentially connected
Can dive into the lower buoyancy aid 1 in water, supporter, preferably middle standing pillar 2, the upper mounting plate 3 that can bubble through the water column.
The front end of lower buoyancy aid 1 is provided with the reamer rack device 4 with watertightness performance, and upper mounting plate 3 is provided with dynamical system,
And guide pile device 5.Embodiments of the invention by being located at the lower buoyancy aid that can dive in water by reamer rack device
On, add maximum dredging depth, so that maximum dredging depth reaches more than 50 meters, can be widely applied to out
Spacious marine site.
As shown in fig. 1, the end of the reamer rack device 4 of embodiments of the invention is preferably provided with reamer, such as figure
Shown in 2, the end of reamer rack device 4 is also provided with bucket wheel, by changing reamer or bucket wheel, the present embodiment
It is applicable to cutter suction dredger, bucket wheel suction dredger.As shown in fig. 1, in the present embodiment, lower buoyancy aid 1
Shape take the shape of the letter U, reamer rack device is set at the notch of U-shaped, rear end arranges pumping system in cabin, pump in cabin
System is provided with piping, and piping includes inhaling mud and the suction pipe of spoil disposal and comb, and piping is connected with reamer rack device.Strand
Cutter holder device submerges in water completely because needing in construction, therefore the suction, discharge pipeline, reamer or the bucket wheel that arrange on it
And drive system, underwater dredge pump and drive system thereof and assembly pulley all have good watertightness performance.
As shown in Figures 3 and 4, in an embodiment of the present invention, middle standing pillar 2 is to be shaped as square body
Shape or cylindrical, quantity six or eight, it is uniformly distributed in the left and right sides of lower buoyancy aid.Due to middle standing pillar
Being distributed in the surrounding of lower buoyancy aid, thus overall water plane area square is relatively big, dredger has enough stabilities；
Simultaneously as the water plane area of middle standing pillar is less, the motion response natural period of dredger is bigger；And
Physical ability of floating downward provides bigger and vertical swings damping, thus dredger has more excellent exercise performance.
As shown in fig. 1, in an embodiment of the present invention, upper mounting plate 3 entirety is rectangle, for single deck or
Box-structure, arranges dynamical system, crane span structure upending frame, guide pile device 5, deck machinery, cabin, goes straight up to
The equipment such as machine platform.
Guide pile device 5 is preferably the location equipment that two sets are identical.Two overlap identical equipment is arranged on upper mounting plate 3
Stern, the preferably left and right sides of upper mounting plate 3 stern；Or guide pile device 5 includes a set of for guide pile
Trolley device, is arranged on the middle part of upper mounting plate 3 stern, and another set of is secondary stake device, is arranged on upper mounting plate 3
The side of stern.Guide pile device 5, through upper mounting plate 3, middle standing pillar 2 and lower buoyancy aid 1, inserts seabed.
The employing mode such as hydraulic jack or winch that hoists of guide pile device 5.
Embodiments of the invention wind-engaging, wave, stream loading are less；Yawmoment is minimum；Direction to environmental load
Insensitive, thus there is excellent capacity of anti-storm.The strong adaptability of the ship type of embodiments of the invention simultaneously,
Can scaling to adapt to different operation sea situation, the demand of operating water depth.
Being described in detail the specific embodiment of the present invention above, but it is intended only as example, the present invention is also
It is not restricted to particular embodiments described above.To those skilled in the art, any the present invention is carried out
Equivalent modifications and substitute the most all among scope of the invention.Therefore, without departing from the spirit of the present invention and model
Enclose lower made impartial conversion and amendment, all should contain within the scope of the invention.
