Abstract
The utility model provides a rotary mooring arrangement which is resilient and elastic, comprising a connecting cylinder, connecting pieces and a mooring base. The utility model is characterized in that it has sitting counterbalances and hanging counterbalances; at the front end of the mooring base and the lower part of each connecting piece, at least one sitting counterbalance is arranged; the hanging counterbalances arranged on the connecting pieces between the cylinder and the sitting counterbalance joint with the connecting pieces and hang together in the water below the connecting cylinder and at least one hanging counterbalance are provided. When more than two hanging counterbalances are provided, serial connection will be arranged among them. A mooring arrangement adopting the above mentioned technical proposal can cut down the drawing force, strengthen the firmness of the mooring base and the resilience and the elasticity of the whole mooring arrangement and increase the energy storage of the connecting pieces. The utility model is also applicable in shallow waters, effectively avoiding the limitation of the prior art and is of small investment and short construction period.
Description
Affiliated technical field
The utility model relates to the mooring gear of boats and ships and the marine facility that floats, and particularly a kind of have good restoring force and an elastomeric turntable type mooring gear, is particularly suitable for the operation at sea of marine floating production storage unit and uses.
Background technology
In the prior art, a kind of comparatively turret mooring device of the marine floating production storage unit mooring of confession commonly used is arranged, this mooring gear is by connecting cylindrical shell, linking part and mooring foundation is formed, connecting cylindrical shell is connected with the main structure of marine floating production storage unit by mechanical locking device, a plurality of mooring foundations link part by many and connect with the cartridge type center shaft that is connected the cylindrical shell center, whole connection cylindrical shell and marine floating production storage unit can be done the weathercock motion of 360 degree around the cartridge type center shaft, make marine floating production storage unit not normally produced by the influence of wind-force and wind direction.This mooring gear has weather vaning capability, and stressed little, reduced investment, production cycle is short, easy to use and advantage such as safe and reliable.But not enough is, and required to link part (as chain etc.) longer, a little less than the constraint very to object space, displacement easily, and the finite energy that links the part savings that suspends, the elasticity that provides mooring required is provided, especially mooring in shallow water, its energy that links part savings can't satisfy the requirement of high sea situation mooring very little.
Summary of the invention
In order to overcome the defective that existing turret mooring device accumulation of energy is little and be difficult to use in shallow waters, the utility model provides a kind of have good restoring force and elastomeric turntable type mooring gear, this mooring gear is simple in structure, practical, savings has higher energy, restoring force is good, and can use in shallow water.
Task of the present utility model realizes by this way: a kind of have good restoring force and an elastomeric turntable type mooring gear, include the connection cylindrical shell, link part and mooring foundation, it is characterized in that also having seat end counterweight and hang counterweight, be provided with at every front end that links part bottom mooring foundation and be no less than a seat end counterweight that places on the seabed at least, hang counterweight and be arranged at linking on the part between connection cylindrical shell and the seat end counterweight, and with respectively link part and be connected and be suspended in the seawater that connects the cylindrical shell below, the quantity that hangs counterweight is no less than one at least, and above suspension counterweight is cascaded on two.
The purpose of this utility model can also take following measure to realize:
Described suspension counterweight can be by being linking part and linking part and be connected thereon.
Described mooring foundation can be that fixed thing is poured into a mould in stake, anchor, pouring weight, anchor ingot and seabed.
The described part that links can be chain, cable or rod shaped structure.
Described rod shaped structure links the metal construction in the available triangle of part, rectangle, trapezoidal, prismatic and T type cross section and makes.
Described seat end counterweight and suspension counterweight can be ore in sand form or river sand, stone, cement concrete, metal piece or the fluid ballast thing of packing.
Each root between suspension counterweight and seat end counterweight links and also is provided with float on the part.
Each root between suspension counterweight and seat end counterweight links and also is provided with auxiliary counterweight on the part.
Described float can be that foamed plastic, plastic tank, metal can and other have the object of buoyancy.
After above-mentioned improvement and since customized design seat end counterweight, the uplift force of mooring foundation is reduced, improve the fastness of mooring foundation effectively.The suspension counterweight is set, can improve the restorability of whole mooring gear, and make this device have the hard and soft self-regulation elasticity mooring property that has both, for enough structural flexibility motion spaces are provided by the motion of mooring object, avoid producing acute motion, reduce mooring load.In addition, owing to be provided with the suspension counterweight, also increase the energy savings when linking part and being raised, improved the stability of mooring gear.Float is set reduces the friction that links part and sea bed, and after auxiliary counterweight is set, when this device when shallow waters uses, the auxiliary device ground of just lying, can reduce friction that links part and sea bed and the stability that improves this mooring gear equally, further improve mooring property, thereby make the application region of this mooring gear can expand different depth of water scopes to.The technical program also has reduced investment, implements and advantage such as production cycle is short easily.
