Description

Technical Field

[0001] The utility model relates to the technical field of dredging ships, and more particularly to a slow drainage device for dredging ships. Background Art

[0002] In the existing technology, a slow drainage device for a suction dredger is a device specially designed for a suction dredger to slowly discharge mud during dredging operations. The main purpose of this device is to reduce the impact on the environment during the drainage process, especially to reduce the pollution of water quality by mud and avoid damage to aquatic ecosystems.

[0003] A common problem with existing suction dredger drainage devices is that sediment enters the drain pipe along with the water flow during the drainage process, which can lead to blockage of the drain pipe. Since the mud generated during dredging operations contains a large amount of solid particles, these particles are easily deposited on the inner wall of the pipe during the drainage process. Over time, the sediment accumulates more and more, eventually forming a blockage. This blockage not only affects drainage efficiency, but may also require cleaning and maintenance of the drain pipe, increasing operating costs and downtime. In addition, long-term blockage may also cause structural damage to the drainage system, further affecting the normal operation of the suction dredger.

[0004] On the other hand, the drainage devices in the prior art often have the problem of inconvenient drainage flow rate adjustment. During dredging operations, the drainage flow rate needs to be flexibly adjusted according to the operating environment and environmental protection requirements to reduce the impact on the environment and improve drainage efficiency. However, the existing drainage devices may lack an effective flow rate adjustment mechanism, or the adjustment process is complicated and requires manual intervention, which not only increases the difficulty of operation, but may also lead to inaccurate drainage flow rate control, thereby affecting the overall effect of the dredging operation. Therefore, developing a device that can easily adjust the drainage flow rate is crucial to improving the flexibility and environmental performance of dredging operations. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a slow drainage device for a dredger, which has the following beneficial effects:

[0018] 1. The anti-blocking mechanism realizes the function of stirring and breaking up the sediment in the drain pipe through the cooperation of the top ring, sealing cover, motor, rotating rod and stirring rod. When there is sediment in the drain pipe, starting the motor drives the rotation of the rotating rod and stirring rod, which can effectively stir and break up the sediment and discharge it with the water flow, preventing the sediment from settling and clogging in the drain pipe. This design improves the patency of the drain pipe, reduces the workload of cleaning and maintenance, and extends the service life of the drain pipe.

[0019] 2. The control mechanism realizes the function of adjusting the drainage flow rate of the drainage device through the cooperation of the connecting pipe, adjusting pipe, adjusting plate, spiral plate and locking sleeve. By rotating the adjusting pipe, the connecting block and the screw rod are driven to rotate, and the adjusting plate is threadedly matched with the adjusting plate, so that the adjusting plate slides along the slide groove to squeeze or stretch the spiral plate, thereby changing the flow space between the spiral plates to realize the adjustment of the drainage flow. This design allows the operator to flexibly adjust the drainage flow rate according to actual needs, thereby improving the adaptability and flexibility of the drainage device.

[0020] 3. The locking mechanism realizes the locking and unlocking function of the control mechanism through the cooperation of the rotating sleeve, the main gear, the screw and the slave gear. By rotating the rotating sleeve, the main gear and the slave gear are driven to engage with each other, thereby driving the screw to rotate and engage with the transmission sleeve threadably, so that the transmission sleeve moves and drives the locking block to move out of the lock groove, realizing the limited fixation of the locking sleeve. This design allows the operator to easily lock and unlock the control mechanism, ensuring the stability and accuracy of the drainage flow rate. At the same time, the existence of the locking mechanism also improves the safety and reliability of the drainage device. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A rust-proof pipe 18 is provided inside the drainage pipe 1, and the two ends of the rust-proof pipe 18 are respectively connected to the top ring 2 and the connecting pipe 7. The setting of the rust-proof pipe 18 effectively prevents rust inside the outer water pipe and extends the service life of the pipe.

This design improves the operating convenience and safety of the equipment.

[0036] The bottom end of the regulating pipe 8 is rotatably provided with a water outlet pipe 24.

[0037] In this embodiment, the drainage pipe 1 is connected to the water storage equipment of the dredger, and the locking mechanism is operated to release the lock of the lock sleeve 13, so that the adjusting pipe 8 can be rotated, and the rotating adjusting rod drives the connecting block 9 to rotate, and the connecting block 9 drives the screw rod 10 to rotate and threadedly cooperate with the adjusting piece 11, so that the adjusting piece 11 slides along the slide groove 23 to squeeze or stretch the spiral piece 12.

When the flow rate becomes faster, the drainage flow rate of the drainage device can be adjusted. When it is adjusted to a suitable flow rate, the transmission sleeve 15 is controlled by the locking mechanism to drive multiple groups of locking blocks 16 to move into the locking groove 14. The locking blocks 16 are pushed to be engaged in the locking groove 14 by the push spring 17, and the locking sleeve 13 is limited and fixed, so that the adjusting tube 8 cannot rotate. When there is sediment stored in the drainage pipe 1, the starting motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the stirring rod 6 to rotate to stir and break up the sediment stored in the drainage pipe 1, so that the sediment is discharged with the water flow.

[0038] See also Figure 4 As an implementation of the locking mechanism: a locking mechanism is provided on the connecting pipe 7, and the locking mechanism includes a rotating sleeve 25, a main gear 26, a screw 27 and a slave gear 28.

The setting of the stoppers 29 prevents the screw rods 27 from excessively rotating during the transmission process, ensuring the correct transmission ratio between the connecting pipe 7 and the transmission sleeve 15. This design improves the transmission accuracy and stability of the equipment.

[0040] More specifically, rotating the rotating sleeve 25 drives the main gear 26 to rotate, so that the main gear 26 and multiple groups of slave gears 28 engage with each other, thereby driving the multiple groups of slave gears 28 to rotate, and at the same time drives the multiple groups of screws 27 to rotate and threadedly cooperate with the transmission sleeve 15, so that the transmission sleeve 15 moves along the screws 27. The movement of the transmission sleeve 15 drives the multiple groups of locking blocks 16 to move out of the lock groove 14, and the limiting fixation of the lock sleeve 13 can be released.

The squeezing of the spiral piece 12 makes the flow space between them smaller, thereby slowing down the flow speed, and the stretching of the spiral piece 12 makes the flow space larger, thereby making When the flow rate becomes faster, the drainage flow rate of the drainage device can be adjusted. When the appropriate flow rate is adjusted, the transmission sleeve 15 is controlled by the locking mechanism to drive multiple groups of locking blocks 16 to move into the locking groove 14. The lock blocks 16 are pushed to be engaged in the locking groove 14 by the push spring 17, and the locking sleeve 13 is limited and fixed, so that the adjusting tube 8 cannot rotate.
