Description

Technical Field

[0001] The utility model relates to a dredging technology, in particular to an underwater dredging device. Background Art

[0002] During operation, the bottom of some sections of the channel along the line is partially deposited with granular debris due to factors such as rainfall and rainwater scouring the slopes around the channel. Larger stones and relatively large debris can be framed by divers underwater and cleaned by lifting equipment or winches. However, smaller gravel, fine sand and silt are deposited on the bottom of the channel for a long time to form a plate-like body, which is difficult to be washed away by the water flow. If divers use underwater bagging and framing to clean, the efficiency is low, and some particles will be washed downstream by the water flow and deposited again. The equipment of the utility model solves the problem that due to the channel width and actual water flow conditions, dredging ships and conventional suction equipment cannot be used to clean the particles deposited on the bottom of some channels, thereby making it inconvenient to dredge the particles deposited on the bottom of the channel.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0015] like Figures 1 to 3 In the embodiment of the underwater silt removal device of the utility model shown in the figure, the underwater silt removal device comprises a sand suction pump 1, a collar 2 is fixedly connected to the sand suction pump 1, a fixing block 3 is fixedly connected to the upper side of the collar 2, a support rod 4 is rotatably connected in the fixing block 3, and buoys 5 are fixedly connected to both ends of the support rod 4, respectively. A water inlet and a water outlet are provided on the sand suction pump 1, a water inlet pipe 6 is connected to the water inlet of the sand suction pump 1 by bolts, and a water outlet pipe 7 is connected to the water outlet of the sand suction pump 1 by bolts. Starting the sand suction pump 1 can extract gravel and fine sand silt with smaller particles through the water inlet pipe 6, a sedimentation tank is set up in the first-level horseway of the channel, and then the sedimentation tank is discharged to the sedimentation tank through the outlet pipe 7. In the pond, clean water flows back into the channel through the side ditch at the foot of the outer slope of the first-level horseway of the channel, and the sand suction pump 1 can be supported by two buoys 5, so that the device can float on the channel water, and the diver dives into the water. The diver controls the position of the flexible hose 8 connected to the water inlet pipe 6 to cooperate with the suction work of the silt underwater. The dredging method of the device has little disturbance to the underwater silt, and the diver can timely grasp the underwater dredging situation without omission, and the cleaning effect is ideal, which is convenient for dredging the particles deposited on the bottom of the channel, and solves the problem that the commonly used dredging and pumping equipment stirs a large area under dynamic water conditions, thereby polluting the water source and having poor efficiency.

[0016] In one embodiment of the present application, preferably, the water inlet pipe 6 and the water outlet pipe 7 are respectively connected with a flexible hose 8. Through the provision of the flexible hose 8, one end of the flexible hose 8 connected to the water outlet pipe 7 can be conveniently placed in a sedimentation tank set up at the first-level horseway of the channel.

[0017] In one embodiment of the present application, preferably, both front and rear ends of the buoy 5 are fixedly connected with hanging rings 9. When the device is in use, two winches can be set upstream and downstream of the repair position to facilitate the control of the movement of the dredging equipment in the channel, and the wire ropes on the winches are respectively connected to the corresponding hanging rings 9.

[0018] In one embodiment of the present application, preferably, a plurality of support rods 10 are connected between the two buoys 5 by bolts. By providing the support rods 10, the connectivity between the two buoys 5 can be strengthened, thereby enhancing the structural stability of the device.

The device can rotate the fixing block 3 on the support rod 4, thereby adjusting the position of the sand suction pump 1, which is convenient to use. By rotating the knob 11, one end of the knob 11 is in contact with the surface of the support rod 4, thereby fixing the adjusted position of the sand suction pump 1.

When smaller particles of gravel, fine sand and silt are extracted through the water inlet pipe 6 and deposited on the bottom of the channel for a long time to form a plate body, the setting of the inclined plate 16 can drive the rotating column 15 to rotate, and then drive the cutter 17 to rotate, so that the plate body can be cut by the cutter 17 and the inclined plate 16, thereby facilitating the breaking of the plate body and facilitating dredging.

[0021] When the utility model is in use, two winches are respectively arranged at the upstream and downstream of the repair position to facilitate the control of the movement of the dredging equipment in the channel. The steel wire ropes on the winches are respectively connected to the corresponding hanging rings 9, so that the position of the device in the channel is controlled by four winches, and one end of the flexible hose 8 connected to the outlet pipe 7 is placed in the sedimentation tank set up at the first-level horseway of the channel. The diver dives into the water and controls the position of the flexible hose 8 connected to the inlet pipe 6 to cooperate with the suction work of the sediment underwater. The construction sequence is easy to be constructed in the reverse direction of the water flow to ensure that the water inlet direction is reversed. In the direction of water flow, the sand suction pump 1 is started to extract smaller particles of gravel and fine sand and silt through the water inlet pipe 6. When smaller particles of gravel and fine sand and silt are extracted through the water inlet pipe 6 and deposited on the bottom of the channel for a long time to form a plate body, the setting of the inclined plate 16 can drive the rotating column 15 to rotate, and then drive the cutter 17 to rotate, so that the plate body can be cut by the cutter 17 and the inclined plate 16, so as to facilitate the breaking of the plate body and facilitate dredging, and then discharged into the sedimentation tank through the outlet pipe 7, and the clean water uses the side ditch at the outer slope foot of the first-level horseway of the channel to flow back into the channel.
