Description

Technical Field

[0001] This utility model relates to the field of rake arm tube flushing pipe technology, specifically a high-efficiency rake arm tube high-pressure flushing pipe. Background Technology

[0002] A trailing suction hopper dredger is a type of suction dredger. It works by sucking in mud through rakes located on the sides or stern of the hull, operating while simultaneously sucking in mud and moving. It utilizes rakes to loosen the soil, and the dredger has an open-bottom mud compartment; the volume of the compartment indicates the size of the dredger. A trailing suction hopper dredger is a large, self-propelled, hopper-type dredger equipped with rake heads and a hydraulic suction system. During dredging, the suction pipe is lowered to the riverbed. Using the vacuum effect of a mud pump, mud is drawn from the riverbed through the rake heads and suction pipe into the dredger's mud compartment. High-pressure nozzles are installed on the rake heads, and high-pressure water jets are mounted on the rake arms. During operation, high-pressure water flows through the high-pressure water jets and is then ejected from the nozzles, breaking up and loosening compacted sand. The cutting and shearing action of the rake teeth further suspends the mud and sand, facilitating its intake into the suction pipe and improving dredging efficiency.

[0003] The horizontal section of the high-pressure water jet pipe on the rake arm tube often adopts a tortuous and circuitous approach, running from the lower end of the rake arm tube. Due to the circuitous nature of the pipeline, it is more time-consuming and labor-intensive to manufacture. In addition, the connecting pipe of the high-pressure water jet section of the slider is connected by a straight pipe, which increases the pipe resistance and weakens the high-pressure water jet effect during high-pressure water jet operation.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This high-efficiency rake arm pipe high-pressure flushing pipe, by setting up connecting hoses, reducing pipes, connecting pipes and water inlet pipes, places the connecting hoses, reducing pipes, connecting pipes and water inlet pipes at the upper end of the horizontal section of the rake arm pipe. The use of a support frame avoids the defects of bending when traveling at the lower end and the time-consuming manufacturing and installation.
