Folding unfolding type inflatable anti-collision connecting bridge

Abstract

The invention provides a folding unfolding type inflatable anti-collision connecting bridge. The connecting bridge is arranged on the outer edge of an offshore oil platform and comprises a protectingshell, an air bag, an inflating device, a pressure sensor, a butt joint device and a positioning sensor; the protecting shell is in a strip shape and is arranged along the outer edge of the offshore oil platform, and the outer side face of the protecting shell is an unfolding shell which can be unfolded under the driving by a motor; and the air bag is contained in the protecting shell, and the butt joint device used for detecting and checking the position of a ship and the positioning sensor are arranged outside the air bag. According to the connecting bridge, alignment, connection and energytransmission between the ship and the platform can be rapidly, accurately and safely realized under the condition that the marine environment is relatively severe; and the device adopts a device whichcan be inflated and unfolded, so that the device can be conveniently unfolded and folded, the occupied area of the device is small.

Description

technical field [0001] The present invention relates to the technical field of offshore platforms, in particular, to a folding and unfolding inflatable anti-collision connecting bridge. Background technique [0002] When the oil tanker loads and transports the oil and gas collected from the offshore oil platform, it often hits the platform, and the alignment is not easy. Since oil tankers are generally heavier, a collision can have very serious consequences. Difficulty in alignment is also one of the main reasons why the ship hits the platform. [0003] The current anti-collision devices are as follows [0004] (1) A bridge pier anti-collision device [0005] Inventor: Cheng Xiaoyan [0006] The device adopts a newly disclosed anti-collision device for bridge piers. By installing blocks on the outer walls of the bridge piers, the device adopts a multi-layer buffer structure design, which has strong buffering capacity during impact and effectively reduces the damage of th...

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
