Description

Very Shallow Water Moorings

The utility model relates to a mooring device for ships, in particular to a mooring device for extremely shallow water, which is suitable for mooring ships in relatively shallow waters.

There are three mooring methods in the prior art: one is chain mooring, which is composed of anchor chains and anchors. , there is no way to meet the needs of mooring under high sea conditions in extremely shallow water mooring; on the moored object. The cable mooring has good structural flexibility, but the disadvantage is that the energy of the catenary is very small, it is easy to wear, and the mooring is troublesome. It also cannot meet the needs of mooring in high sea conditions; the third is chain plus counterweight mooring. This mooring can increase the resilience, but it is still difficult to provide the flexibility required for mooring, and mooring in extremely shallow water also cannot meet the needs of mooring in high sea conditions.

The purpose of the utility model is to provide a new design of an extremely shallow water mooring device which is suitable for use in extremely shallow water, has both rigidity and flexibility, and occupies a smaller water area.

The above tasks are achieved in such a way: the mooring device is composed of a mooring foundation, a ground connection piece, a bottom counterweight, a connection piece, a float, a connection piece, a suspension counterweight, a connection piece, a buoy connected with connecting parts in sequence.

The purpose of this utility model can also take the following measures to achieve:

The mooring foundation can be piles, anchors, weight blocks, anchor spindles and seabed surrounding injection consolidations.

The ground connection can be a chain, a cable, or a mooring arm.

The link can be a chain or a cable.

The material used for the counterweight at the bottom of the seat and the counterweight for suspension can be packaged ore sand or river sand, stones, concrete blocks, metal parts or fluid ballast.

The floater can be foam plastics, plastic tanks, metal tanks and other objects with surplus buoyancy.

The buoy is welded with steel plates.

The mooring foundation is connected with the ground link through a rotatable joint on its top surface. The rotatable joint may be a universal joint, a ball joint, a swivel, a link, or the like.

After adopting the above-mentioned new design, due to the special design of the lying connection piece, the upward pulling force of the mooring foundation can be reduced to zero, and its firmness can be effectively improved. The setting of the counterweight and the float can improve the recovery force of the device and the utilization rate of the tension, so that the device has both rigid and flexible mooring characteristics, providing enough structural flexible movement space for the movement of the moored object, and mooring The movement of the object is controlled within the flexible range of the mooring device structure, and the moored object should be avoided from excessive movement within the range of the elastic high stress end of the mooring device material.

Compared with the prior art, the utility model has the following advantages:

1. The device has good structural elasticity, which can effectively reduce the mooring load;

2. Reduce the movement in the elastic high stress end range of the mooring device material;

3. Improved mooring characteristics and reduced device fatigue;

4. Replacing material flexibility with structural flexibility to further reduce the requirements for water area;

5. The operation is more convenient, safe and reliable;

6. The least investment and the shortest construction period;

7. The application area is extended to extremely shallow water areas, which can be used in offshore, harbors, rivers, and lakes;

8. It can play a positive role in promoting the loading and unloading of liquid bulk cargo, the mooring of marine tourism facilities and marine aquaculture facilities, reduce construction investment and loading and unloading costs, and play a role in the development of energy transportation, tourism, and marine aquaculture. Active promotion.

Below in conjunction with accompanying drawing, the structure of the present utility model is further described.

Fig. 1 is the schematic diagram of a kind of structure of the utility model;

Fig. 2 is a reference diagram of the utility model using state;

FIG. 3 is a top view of FIG. 1 .

As shown in Figure 1, the utility model is composed of a mooring foundation 1, a ground connection part 2, a bottom counterweight 3, a connection part 4, a float 5, a connection part 6, a suspension counterweight 7, a connection part 8. The buoy 9 and the connecting piece 10 are connected in sequence. Mooring foundation 1 uses anchor ingots, ground connecting parts 2, connecting parts 4, 6, and 8 use chains, seat bottom counterweight 3 uses mixed chain soil blocks, and suspension counterweight 7 adopts ore sand and is installed in a container production. Float 5 adopts foamed plastics to make. The buoy 9 is welded with steel plates, the connecting piece 10 is made of a steel wire cable, and the connection between the mooring foundation 1 and the lying connecting piece 2 is connected by a swivel 11 .

The utility model is particularly suitable for mooring marine objects in extremely shallow water.
