The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
In order to solve the problems that the loading and unloading efficiency is low and drainage needs to be done in the transportation process of a barge due to the fact that the dredged soil loaded into the barge contains a large amount of water, the invention provides a loading and unloading structure of a trailing suction hopper dredger, which comprises a loading and unloading mud pipe 1, a supporting member 2, a mud discharge pipe 3, a hose 4, an annular water baffle 5, a T-shaped energy dissipation loading and unloading pipe 6 and a telescopic piece 7, and is shown in figures 1 to 5;
the mud charging and refuting pipe 1 comprises a straight pipe section 8 and an inclined pipe section 9, the inlet end of the inclined pipe section 9 is higher than the outlet end, the inlet end of the inclined pipe section 9 is communicated with the straight pipe section 8, the inlet end of the inclined pipe section 9 and the straight pipe section 8 can be connected through a bent pipe in a welding mode, the outlet end of the inclined pipe section 9 is a sand outlet, the cross section area of the inclined pipe section 9 is gradually reduced from the inlet end to the outlet end, an opening is formed in the side wall, far away from the water surface, of the inclined pipe section 9, a filter screen 10 is detachably mounted in the opening, and the outlet end of the inclined;
the support member 2 is installed on a boat body 11 of the dredger, the hose 4 is installed on the support member 2, one end of the hose 4 is communicated with the mud discharging pipe 3, the other end of the hose is communicated with the straight pipe section 8, the annular water baffle 5 is sleeved on the outer wall of the inclined pipe section 9 and located between the filter screen 10 and the outlet end, and the telescopic piece 7 is installed on the boat body 11 and connected with the straight pipe section 8.
When the drag suction dredger adopts the loading and barge structure, the dredged soil dug by the drag suction dredger with flow velocity is transported into the mud discharging pipe 3, is impacted to the straight pipe section 8 of the loading and barge pipe 1 through the mud discharging pipe 3, and is impacted to the inclined pipe section 9 through the straight pipe section 8, when the dredged soil is impacted to the inclined pipe section 9, as shown in fig. 3, because the filter screen 10 is positioned on the outer wall of the inclined pipe section 9 far away from the water surface, namely on the upper side wall of the inclined pipe section 9, the dredged soil impacts the filter screen 10, so that the water in the dredged soil is discharged through the filter screen 10, the filter screen 10 blocks the sediment in the dredged soil, the sediment continues to flow in the inclined pipe section 9, and is finally transported into the barge through the T-shaped energy dissipation loading pipe 6, because the cross-sectional area of the inclined pipe section 9 from the inlet end to the outlet end is gradually reduced, the flow velocity of the dredged soil in the loading and the dredged soil impact force on the filter screen 10 is further, the effect of separating water from silt is achieved, the moisture of dredged soil entering the barge is greatly reduced, the utilization rate of the space of the barge is improved, meanwhile, the water drainage treatment in the cabin of the barge is not needed, and the workload is reduced; an annular water baffle 5 is arranged between the filter screen 10 and the outlet end of the inclined pipe section 9, and when water flow discharged from the filter screen 10 flows to the annular water baffle 5 along the outer wall of the inclined pipe section 9, the water flow can fall into a river or sea water along the annular water baffle 5 to prevent the water flow discharged from the filter screen 10 from flowing to a mud barge along the outer wall of the inclined pipe section 9; the action that extensible member 7 can be through extension or shorten drives the dress and refutes mud pipe 1 and revolve around hose 4, on the one hand, can constantly adjust and refute the position that the pipe 6 was refuted to the T type energy dissipation dress that mud pipe 1 is connected with the dress, make T type energy dissipation dress refute the silt in the pipe 6 and evenly adorn in the hopper barge hold, guarantee the safety and stability of dress mud in-process hopper barge, the dress time of refuting has been shortened, on the other hand, can make the dress refute mud pipe 1 fast turn through extensible member 7, make the dress refute mud pipe 1 and realize vibrations, can make the silt vibrations of jam on filter screen 10 drop, wherein install extensible member 7 in straight tube section 8, can avoid the water-washed brush extensible member 7 that comes through filter screen 10 outflow, produce adverse effect to extensible member 7.
As shown in fig. 2, in the present invention, the support member 2 comprises an outer frame 12 and a support bar 13, the support bar 13 is supported on the hull 11, the outer frame 12 is mounted on the support bar 13, the hose 4 is fixed in the outer frame 12, and the outer wall of the other end of the hose 4 is fixed on the inner wall of the straight pipe section 8, so that the rotation of the mud filling pipe 1 is not affected.
In the present invention, preferably, the included angle between the inclined pipe section 9 and the horizontal plane is α, α is not less than 25 ° and not more than 40 °, if α is too large, the working length of the mud loading pipe 1 is short, so that the mud and sand cannot smoothly enter the mud barge, and if α is too small, the dredged soil cannot sufficiently wash the filter screen 10, and the water and sand in the dredged soil cannot be effectively separated.
In the invention, the telescopic part 7 can be a hydraulic telescopic rod, and the extension of the hydraulic telescopic rod can be controlled manually or by a motor.
In the present invention, the outer wall of the loading mud pipe 1 is coated with an anticorrosive coating, such as paint, so that the loading mud pipe 1 can be prevented from being corroded.
In the invention, the grain sizes of silt in the dredged soil are different according to different working places of the trailing suction hopper dredger, so that the filter screens 10 with different apertures are selected according to different working places, water can be discharged through the filter screens 10, and the silt is blocked by the filter screens 10; in the invention, the filter screen 10 is arranged in the opening through the bolt, so that the filter screen 10 is detachably connected with the inclined pipe section 9, the filter screen 10 can be detachably replaced, when the harrow suction dredger works in different places, the filter screens 10 with different apertures can be arranged, the applicability is wider, on the other hand, if the filter screen 10 is damaged, only the filter screen 10 is replaced, the whole mud pipe 1 is not required to be replaced, the material is saved, and the maintenance process is convenient.
As shown in fig. 5, the T-shaped energy dissipation barge 6 comprises an inclined pipe 14 and a horizontal pipe 15, the inclined pipe 14 is communicated with the middle of the horizontal pipe 15, the outlet end of the inclined pipe section 9 is communicated with the inclined pipe 14, and when silt is transported to the joint of the inclined pipe 14 and the horizontal pipe 15, the flow direction of the silt flow can be changed, the impact of the silt flow on the barge is reduced, and the stability of the barge is ensured.
