Description
Technical Field
The invention relates to the technical field of ocean platforms, in particular to a folding and unfolding type inflatable anti-collision connecting bridge.
Background
When the oil tanker loads and transports oil gas collected by the offshore oil platform, the oil tanker often collides with the platform and is not easy to align. Since the tanker is generally heavy, the impact can have very serious consequences. The difficulty in alignment is also a main cause of the impact of the ship on the platform.
The current anti-collision device is as follows
(1) Pier buffer stop
The inventor: chengdou swallow
The device is with novel a pier buffer stop who discloses, through at pier outer wall mounting thing piece, adopts multilayer formula buffer structure design, and buffer capacity is strong during the striking, effectively reduces the damage of pier under huge impact force.
(2) Floating pier anti-collision device
The inventor: kongjin river
The device is arranged at the periphery of a pier and is characterized by comprising a steel skeleton, an air bag and a guide assembly, wherein the steel skeleton is formed by welding angle steel or square steel pipes, an air bag installation space is arranged in the steel skeleton, the air bag is fixed in the space, a steel plate is fixed on the inner side of the steel skeleton, and the guide assembly is fixed on the steel plate; the surface of the steel skeleton is covered with a layer of rubber film, and the rubber film forms a smooth surface. In the invention, the air bag part is exposed on the river surface and can be coated with warning color for safety prompt. The steel skeleton can carry out the self-adaptation regulation of upper and lower position along the pier along with the change of river course surface of water under the drive of gasbag, has solved the problem that safeguard measure can not carry out the altitude mixture control among the current protection system. Safety protection can be better carried out to the bridge, the problem of the bridge life decline that avoids causing because the striking.
(3) A buffer stop for boats and ships
The inventor: wu Guo Hua
Including two effect single piston hydro-cylinders and gasbag subassembly, two effect single piston hydro-cylinders and gasbag subassembly are installed in the inside of wall body in proper order in turn, two effect single piston hydro-cylinders are provided with rodless chamber and have the pole chamber in the inside of wall body, two effect single piston hydro-cylinders are keeping away from the one end fixedly connected with rubber fender of wall body the middle surface fixedly connected with first electro-magnet of rubber fender the middle surface of first electro-magnet is provided with laser displacement sensor, the gasbag subassembly is in the inside second electro-magnet that is provided with of wall body, the one end sliding connection of second electro-magnet has magnet the one end intercommunication of magnet is connected with the gasbag. The anti-collision device for the ship can avoid economic loss caused by collision through the double-acting single-piston type oil cylinder and the air bag assembly, and has high use value.
The former two kinds of pier buffer stop one kind is through installing thing piece multilayer buffering formula structure, and another kind comprises steel skeleton, gasbag and direction, and wherein the steel skeleton is formed by angle steel or square steel pipe welding, and two kinds all can effectively and safely protect the pier, and the gasbag is in the gas filled state always. The third protection device for protecting the ship realizes the protection of the ship through the double-acting single-piston type oil cylinder and the air bag assembly, and the air bag is always in an inflated state.
In the technique that exists at present, protector all is fixed unchangeable, and is adjustable, and first kind pier protector can not remove along with the surface of water, and the second kind though can reciprocate but can not shrink, and these two kinds of protector are only applicable to the pier, but not fully satisfactory at offshore platform.
