Description

Technical Field

[0001] This invention belongs to the field of submarine technology, and in particular relates to a river estuary tracing submarine. Background Technology

[0002] The estuary-tracing submarine is an underwater powered device that uses nozzle jets to trace the source of rivers. It is unmanned, propellerless, rudderless, and has no detour radius. Its two ends are mutually forward and backward, making it highly maneuverable underwater. It has a strong sand-flooding ability, directly guides the sand dunes that block the river, lowers the river mouth below the sea surface, increases the flow velocity, and enhances the ability to carry sand into the sea.

[0003] Under the combined action of water and sediment transport, sediment carried upstream is transported to the river mouth. However, due to the backwater effect of the ocean, the flow conditions at the river mouth are restricted, disrupting the conditions for water and sediment transport. This leads to sediment deposition at the river mouth, forming barrier dunes that impede the smooth flow of river water and sediment into the sea. This results in the phenomenon of the river mouth swaying and the riverbed rising, with the suspended riverbed of the Yellow River estuary being a typical example. Sedimentation at the river mouth not only affects navigation channels and the estuarine ecosystem but also reduces the efficiency of water and sediment transport, increasing flood control and management costs.

[0004] However, existing estuary dredging and sediment removal technologies typically rely on manual or mechanical vessel operations, which suffer from drawbacks such as low efficiency, high construction costs, poor mobility, inability to operate continuously for extended periods, and difficulty in simultaneously achieving estuary headwaters transport and sediment removal. Furthermore, traditional devices are easily obstructed in shallow water or complex environments with sand dunes, failing to fully utilize the co-movement of water and sediment, thus making it difficult to completely resolve sediment deposition problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the invention is to provide a river mouth tracing submarine that can effectively dredge the river mouth, improve the conditions for water and sediment co-movement, enhance the utilization value of sediment, and provide an efficient and economical engineering solution for the treatment of suspended rivers and river mouth dredging.

[0006] This invention proposes a river estuary tracing submarine, comprising: a shuttle-shaped body, a base plate, a balance chamber, a pressure main pipe, a water intake system, a pressurization system, a jet drive system, and a sand-cultivating jet system; The spindle-shaped body is disposed above the substrate, and the balance chamber is disposed below the substrate; The water inlet system includes a left water inlet located on the left side of the spindle-shaped body and a right water inlet located on the right side of the spindle-shaped body; The pressurization system includes a left pressurization device and a right pressurization device. The left inlet is connected to the left pressurization device, and the right pressurization device is connected to the right inlet. Both the left and right pressurization devices are connected to the pressure main pipe. The jet drive system includes a front branch pipe, a rear branch pipe, a front nozzle regulating valve, and a rear nozzle regulating valve. The front branch pipe and the rear branch pipe are both connected to the pressure main pipe. The front nozzle regulating valve is located on the front branch pipe, and the rear nozzle regulating valve is located on the rear branch pipe. The sand-cultivating jet system includes a sand-cultivating branch pipe, a front sand-cultivating nozzle regulating valve, and a rear sand-cultivating nozzle regulating valve. The sand-cultivating branch pipe is connected to the pressure main pipe. The sand-cultivating jet system is used to flush the sand dunes at the river mouth, so that the deposited sediment is disturbed and transported into the sea with the river mouth water flow. The pressure header is used to supply high-pressure water flow to the jet drive system and the sand-cultivating jet system to drive the estuary source-tracing submarine to move forward, backward, translate, and rotate, and to carry out scouring, disturbance, and transport operations on the estuary sediment.

[0007] The beneficial effects of this invention are as follows: In this embodiment of the invention, the estuary-tracing submarine, through its compact structural design of a shuttle-shaped body, base plate, and balance chamber, combined with a water intake system, a pressurization system, a jet drive system, and a sand-cultivating jet system, achieves unmanned underwater operation and flexible maneuverability. It can move forward, backward, translate, and rotate in the complex environment of the estuary. At the same time, it uses high-pressure nozzles to flush the barrier dunes and transport sediment into the sea, thereby effectively dredging the estuary, improving the conditions for water and sediment movement, enhancing the utilization value of sediment, and providing an efficient and economical engineering solution for the treatment of suspended rivers and estuary dredging.
