Description

Technical Field

[0001] This utility model relates to the field of dredging engineering technology, and in particular to an adjustable underwater mud pump assembly. Background Technology

[0002] A cutter suction dredger is a commonly used engineering vessel. The underwater pump unit and the front-end cutter cutting device are its important construction equipment. The proper matching of the pipeline length between the two directly determines the vessel's suction performance, the concentration of the transported mud, and the construction capacity.

[0003] Traditional underwater pump units are installed in a fixed position, and their location does not change once installed. However, the pipeline distance between the underwater pump unit and the front-end cutter head varies depending on the soil conditions being excavated. The traditional installation method cannot ensure that the pipeline between the underwater pump unit and the front-end cutter head remains in optimal condition under any construction soil conditions. This results in insufficient front-end suction performance, reduced mud concentration, and decreased overall construction performance of the vessel. Utility Model Content

[0018] Example Please see Figure 1 and Figure 2 This embodiment provides an adjustable underwater mud pump assembly, which consists of an underwater pump unit 1, a movable base 2, a rotatable adjustable inlet suction pipe 3, a cable retraction device 4, and an underwater pump displacement traction device 5.

[0019] The underwater pump unit 1 is fixed on a movable base 2, which is installed inside the cutter suction dredger bridge 6 and can move along the bridge. One end of the rotatable adjustable inlet suction pipe 3 is connected to the suction port of the cement slurry pump, and the other end is connected to the slurry pipe on the bridge after the underwater pump unit moves to the correct position. The cable reeling device 4 is used to adjust the length of the cable connected to the underwater motor of the underwater pump unit according to the position of the underwater pump unit 1; the underwater pump displacement traction device 5 is used to adjust the length of the traction steel wire rope connected to the movable base 2 according to the position of the underwater pump unit 1.

[0020] In a preferred embodiment, the movable base 2 is installed in the slide groove of the cutter suction dredger bridge 6 and can move back and forth along the slide groove direction of the bridge 6. The movable base 2 is arranged in a specific slide groove of the cutter suction dredger bridge 6 and can move back and forth along the slide groove direction. After moving to the designated position, it is fixed by the limiting device on it to ensure the stability of the underwater mud pump assembly during normal operation.

[0021] In a preferred embodiment, the cable winding and unwinding device 4 includes a cable winding and unwinding winch 41 and a cable guiding mechanism and its support 42. The movable end of the cable of the cable winding and unwinding winch 41 is connected to the underwater motor of the underwater pump unit 1 through the cable guiding mechanism. By winding and unwinding the cable through the cable winding and unwinding winch 41, the cable length is kept at the optimal level after the underwater pump unit is moved, meeting the construction needs after the underwater pump unit's position is adjusted.

[0022] In a preferred embodiment, the cable reeling and deployment device 4 is arranged on the side buoy of the cutter suction dredger. The movable end of the cable in the cable reeling and deployment device 4 is connected to the underwater motor of the underwater pump unit 1, and the cable length can be freely adjusted as the position of the underwater pump unit 1 moves, eliminating the problem of needing to adjust the wiring again due to insufficient power line length when the position of the underwater pump unit 1 is adjusted.

[0023] In a preferred embodiment, the underwater pump displacement traction device 5 includes a traction winch 51 and at least two traction wire rope guide mechanisms and their supports. The movable end of the traction wire rope of the traction winch 51 is connected to the movable base 2 through each traction wire rope guide mechanism.

[0024] In this embodiment, three traction wire rope guiding mechanisms and their supports are provided. The first traction wire rope guiding mechanism and its support 52 is arranged on the side buoy of the cutter suction dredger, while the second and third traction wire rope guiding mechanisms and their supports 53 and 54 are arranged on the bridge frame 6, located on the left and right sides of the bridge frame 6. When the position of the underwater pump unit 1 needs to be adjusted, the traction wire rope is raised and lowered by the traction winch 51, pulling the movable base 2 to move on the bridge frame 6. After moving to the appropriate position, the movable base 2 is locked to ensure that the relative position between the underwater pump unit 1 and the front-end cutter cutting device 7 is always optimal.

[0025] In a preferred embodiment, the underwater pump relocation and traction device 5 is arranged on the side buoy of the cutter suction dredger. The movable end of the traction wire rope of the underwater pump relocation and traction device 5 is connected to the movable base 2. By raising and lowering the traction wire rope, the position of the underwater pump unit 1 on the bridge of the cutter suction dredger is changed to ensure that the relative position between the underwater pump unit 1 and the front cutter cutting device 7 is always optimal when excavating different soil types.

[0026] In a preferred embodiment, the cable reeling and unloading device and the underwater pump relocation and traction device are located on both sides of the cutter suction dredger to ensure a reasonable layout.

[0027] During installation, the underwater pump unit is fixed on a movable base, which is arranged on the bridge of the cutter suction dredger. It can move along a special groove on the bridge. The cable is wound and released by the cable winding winch 41 and the traction winch 51 to wound and release the traction wire rope, so that the distance between the underwater pump unit and the front-end cutter cutting device is optimal. Then, the movable base is fastened by the limiting mechanism, and then the inlet and outlet pipelines of the underwater mud pump are quickly connected.

[0028] This invention designs an adjustable underwater mud pump assembly to ensure optimal piping between the underwater pump unit and the front-end cutter cutting device, thereby guaranteeing the suction performance of the underwater mud pump, maximizing the concentration of pumped mud, and improving the construction capacity of the cutter suction dredger. Compared with the fixed underwater mud pump assembly of traditional cutter suction dredgers, this is an effective innovation that can be widely promoted and applied in the design and construction of cutter suction dredgers.
