This application claims the priority of the Chinese patent application filed on May 7, 2022, with the application number 202210493609.1 and titled "Suspended River Control Device and Suspended River Control Sand-churning Boat", the full text of which is hereby incorporated by reference.

Technical field

This application relates to the technical field of environmental protection equipment, in particular to suspended river management devices and suspended river management sand stirring boats.

Background technique

The so-called hanging river refers to a river whose river bed is higher than the ground on both sides of the bank. It is also called an "above ground river". The middle reaches of the Yellow River flow through the loose Loess Plateau. The river water carries a huge amount of sediment and flows downstream. The sediment continues to accumulate, causing the river bed to rise continuously. High, the water level rises accordingly, and it faces the threat of floods every flood season. At present, the total length of the "hanging river" area of the Yellow River has exceeded 800 kilometers. The hanging river management devices in related technologies mainly include cutter suction ships and rake suction ships. Both of them stir the river bed sediment to mix the water and sand into mud. The suction pipe sucks the mud into the pump body and sends it to the mud discharge area through the mud discharge pipe. However, this "digging and transporting" method makes the dredging efficiency low and causes energy loss.

In one embodiment, the suspended river management device further includes a jet component, which includes a jet component 430 and a nozzle 410; the jet component 430 is installed on the fixed plate 100 or the hull 510, and is used to generate jet fluid; the inlet of the nozzle 410 is connected to The outlet of the jet component 430 is used to eject the jet fluid generated by the jet component 430 through the nozzle 410 to raise the riverbed sediment. It should be noted that the jet fluid here refers to a fluid with a relatively high pressure, for example, a fluid with a pressure >0.3MPa. The fluid may be water flow, air flow, etc.

Specifically, the jet member 430 generates jet fluid and ejects it through the nozzle 410, so that the jet fluid ejected from the nozzle 410 has a greater impact force. When the jet fluid is ejected on the river bed sediment, it can stir the river bed sediment; When the fluid is sprayed into the water flow, the sediment carried by the sand stirring member 310 in the water flow can be further lifted upward, thereby increasing the distance that the water flow drives the sand to travel downstream, and improving the desilting efficiency. In one embodiment, the fluidic component 430 is a high-pressure pump.

In one embodiment, the nozzle 410 is installed on the outer peripheral surface of the roller shaft 320, and the nozzle 410 is configured to be able to rotate driven by the roller shaft 320 to change the spray direction of the jet fluid ejected through the nozzle 410, so that the nozzle 410 can rotate.

At the same time, when the nozzle 410 rotates synchronously with the roller 320, the roller 320 also applies a certain power to the jet fluid ejected from the nozzle 410, thereby increasing the impact force of the jet fluid, thereby causing the sediment to be impacted by the jet fluid. It can be raised further upon impact. Among them, the nozzle 410 and the sand-stirring piece 310 are both installed on the outer peripheral surface of the roller shaft 320. The rotation of the sand-stirring piece 310 and the nozzle 410 is realized through the roller shaft 320, thereby saving energy.

Since the sediment is constantly being lifted up, that is, the sediment can always be located in the water layer with higher water flow. When the water flow drives the sediment downstream, the sediment can travel a longer distance, realizing the transportation of the sediment. Improve dredging efficiency. Among them, the nozzle 410 and the sand stirring member 310 are arranged in a staggered manner. When the nozzle 410 sprays the jet fluid toward the river bed, it can reduce the impact on the hook 312 to grasp the river bed sediment.

Specifically, the jet fluid generated by the jet component 430 flows into the flow channel 321, and then is sprayed out from a plurality of nozzles 410 connected to the outer circumferential surface of the roller shaft 320, thereby achieving impact on the sediment in the water flow. This method of arranging the flow channel 321 connecting the outlet of the jet member 430 and the inlet of the nozzle 410 reduces the installation of other components and makes the structure of the device more compact.

Furthermore, the diameter of the nozzle of the nozzle 410 is much smaller than the diameter of the flow channel 321, so that the pressure of the jet fluid ejected from the nozzle 410 is greater and the impact force is stronger, thereby being able to remove the sand stirred up by the sand stirring member 310 in the water flow. The sediment is carried higher up in the current.
