Pile-washing-out monitoring device for self-elevating platform

Abstract

The invention relates to a pile-washing-out monitoring device for a self-elevating platform. The pile-washing-out monitoring device comprises a seawater collection header pipe, wherein a pile-washing-out hose is connected to the water outlet end of the seawater collection header pipe, a pile-washing-out pipe is connected to the water outlet end of the pile-washing-out hose, an annular spray pipe is connected to the lower end of the pile-washing-out pipe, a plurality of nozzles are arranged on the annular spray pipe, and a pump inlet control valve, a high-pressure jet water pump, a pump outletcheck valve, an isolating valve, an upper pile-washing-out control valve and a lower pile-washing-out control valve are connected between the seawater collection header pipe and the pile-washing-out hose in sequence. By means of the pile-washing-out monitoring device, the flowing state and relative flow speed of liquid in the pile-washing-out pipeline are displayed in real time, the purpose of remotely judging whether or not water flow is injected to the bottom of a pile shoe, and judging the amount of the injected water flow is achieved, the next pile pulling operation is conveniently judged,the workload for pile pulling is greatly reduced, the time for pile pulling is greatly shortened, and the efficiency of pile cleaning and pile pulling is improved.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a self-elevating platform pile flushing monitoring device. Background technique [0002] In the 21st century, with the continuous growth of energy consumption in our country, the development strategy of developing marine resources and developing clean energy is constantly expanding, and offshore wind power generation, as an inexhaustible new energy source, is being favored by more and more people. The development of wind power projects requires the use of wind power installation ships, a self-elevating offshore engineering platform. The most critical technology of the platform is that the entire hull can be lifted above the water surface through a set of leg lifting systems, so that It is not disturbed by wind and waves, and it is convenient for the installation and maintenance of wind power generation equipment. The insertion and removal process of pile legs is an indispensable process in ...

AI Technical Summary

Problems solved by technology

[0003] Because the pile boots are buried in the seabed mud after a long period of pressure, it is difficult to inject pile flushing water. The length of flushing piles and the amount of water vary greatly depending on the seabed conditions, and the pile flushing pipeline is a Fully enclosed high-pressure system, so it is impossible to judge the progress of the pile flushing during the pile flushing process. It can only be judged by repeated trials, which is laborious and inconvenient
