A folding and unfolding inflatable anti-collision connecting bridge

Abstract

The invention provides a foldable and unfoldable inflatable anti-collision connecting bridge, which is arranged on the outer edge of an offshore oil platform, and includes: a protective shell, an air bag, an inflatable device, a pressure sensor, a docking device, and a positioning sensor; the protective shell is a strip It is installed along the outer edge of the offshore oil platform, and the protective shell is an expansion shell that can be expanded under the electric drive. The airbag is stored inside the protective shell, and the docking device and positioning device for detecting and correcting the position of the ship are arranged outside the airbag. Sensor; the present invention can quickly, accurately and safely realize the alignment, connection and energy transmission of the ship and the platform under the relatively harsh conditions of the marine environment. Since the device adopts an inflatable device, the device can be conveniently deployed and stows away so the unit has a small footprint.

Description

technical field [0001] The invention relates to the technical field of offshore platforms, in particular to a foldable and unfoldable inflatable anti-collision connecting bridge. Background technique [0002] When an oil tanker loads and transports the oil and gas collected by an offshore oil platform, it often hits the platform, and alignment is difficult. Since tankers are generally heavy, collisions can have very serious consequences. Difficulty in alignment is also one of the main reasons for the ship to hit the platform. [0003] The current anti-collision device is as follows [0004] (1) A bridge pier anti-collision device [0005] Inventor: Cheng Xiaoyan [0006] The device uses a newly disclosed anti-collision device for bridge piers. By installing blocks on the outer wall of the piers and adopting a multi-layer buffer structure design, the buffer capacity is strong during impact, and the damage of the bridge piers under huge impact force is effectively reduced....

AI Technical Summary

Problems solved by technology

[0014] In the current existing technologies, the protection devices are fixed and cannot be adjusted. The first type of pier protection device cannot move with the water surface, while the second type can move up and down but cannot shrink. These two protection devices are only applicable On the bridge pier, it is unsatisfactory to put it on the offshore platform

The protective device of the third ship is more suitable for ships and occupies a larger area, and the airbag of the device is always inflated, so it is not easy to retract

If the device is placed on an offshore platform, it will increase the weight of the platform and have a great impact on the work of the platform

More importantly, none of the above-mentioned devices can realize fast, accurate positioning and safe connection between the ship and the platform, especially when there are strong winds and waves at sea, the above-mentioned devices cannot realize fast, accurate and safe connection between the ship and the offshore platform

If the positioning and accurate connection cannot be realized, it is impossible to guarantee the floating of the ship due to the action of sea wind and waves during the process of oil and gas transmission. This kind of floating will easily cause the collision between the ship and the platform.

If the impact occurs during the transmission process, this impact may also cause oil and gas leakage, fire or even explosion
