Multifunctional pile leg applicable to ocean platform

Abstract

The invention discloses a multifunctional pile leg applicable to an ocean platform. The multifunctional pile leg comprises a pile leg main body and a pile shoe. The pile shoe is a sealed hollow shell.The bottom of the pile leg main body is connected with the top of the pile shoe. The multifunctional pile leg further comprises a jetting mechanism and a seawater lifting device. The jetting mechanism comprises an upper jetting unit and a lower jetting unit which are mutually independent. A water conveying pipe is vertically arranged between an upper conveying pipe and a lower conveying pipe. Thewheel face of a guide pipe pulley abuts against the upper conveying pipe or the lower conveying pipe. A rope coiling device pulls the water conveying pipe to slide up and down along a gap between theupper conveying pipe and the lower conveying pipe through a guide pipe pulley mechanism. The seawater lifting device is arranged on a truss of the pile leg main body. The water conveying pipe is controlled to ascend and descend in the truss of the pile leg main body through the rope coiling device mounted on the ocean platform so that seawater can be extracted rapid; and the jetting mechanism isarranged for assisting in pulling out the pile shoe, and rapid pull-out of the pile shoe is achieved.

Description

technical field [0001] The invention relates to the field of ocean platforms, in particular to a multifunctional pile leg suitable for ocean platforms. Background technique [0002] An ocean platform is a common ocean engineering equipment, which mainly includes a platform body and legs. The main body of the platform extends the legs into the bottom of the sea through the lifting system. When the legs reach the bottom of the sea, it can raise the main body of the platform to a certain height and carry the weight of the main body of the platform. A stable offshore platform is built through the support of the legs and shoes. Working platform; when transferring, pull up the pile legs, lower the main body of the platform and float on the water surface, and then it can be towed to another place. For the sealed spud cans, the interior is not connected to the outside world, so the upper surface of the sealed spud cans will be subjected to soil accumulation and seawater pressure du...

AI Technical Summary

Problems solved by technology

Since the offshore platform is generally more than 10 meters above the sea level, the length of the steel structure tower is required to be more than 10 meters, with many consumables and high cost; moreover, a complex lifting mechanism is required to drive the tower up and down, which consumes a lot of energy and costs. high difficulty
