Description

Novel mooring buoy

Technical Field

The invention relates to the field of offshore ship mooring equipment facilities, in particular to a buoy for docking ships or offshore equipment.

Background

To develop the mineral resources of magas in africa, it is planned to build a ship-out terminal on the south west coast of magas. However, the lack of local bulk carrier ports and docks required to export these titanium ore resources has necessitated finding a suitable way to ship these ores in order to develop local economies and solve civil problems without expending significant capital and time. To this end a multi-point mooring system has been developed to replace the conventional wharf. In the multi-point mooring system, a connecting shaft of the existing buoy is positioned on a central axis in the buoy (as shown in fig. 1), and the connecting shaft has the problems of large inclination angle (as shown in fig. 2), poor stability, susceptibility to seawater erosion of equipment on the buoy and the like during normal operation.

Disclosure of Invention

In order to solve the above problems, the present invention provides a novel mooring buoy, which aims to achieve the purpose of ensuring the buoy to be always in a balanced state in the working process and avoiding an overlarge inclination angle, and adopts the following technical scheme:

a novel mooring buoy is provided with a cylindrical barrel, wherein a circular upper deck is arranged at the top of the barrel, a circular bottom plate is arranged at the bottom of the barrel, and the circle centers of the upper deck, the bottom plate and the barrel are the same; the edge of the upper deck is provided with a sector platform which is sunken downwards, a quick release hook is fixed at the platform, and the quick release hook is fixed on the platform through a release hook base; a connecting shaft extends towards the edge of the base plate opposite to the releasing hook base in the barrel by taking the releasing hook base as a starting point, and a lifting lug is fixed at the end part of the connecting shaft and penetrates through the base plate; the outer surface of the cylinder body is covered with anti-collision rubber.

Above-mentioned novel mooring buoy, further, the connecting axle with the bottom plate axis forms 45 degrees contained angles.

Above-mentioned novel mooring buoy, further, quick release hook is connected with the boats and ships that moor through the mooring line, the lug is connected with the grabbing power anchor through the mooring anchor chain.

In the novel mooring buoy, a circle of guardrail is arranged along the edge and the circumferential direction of the upper deck.

In the novel mooring buoy, further, a guide ballast anchor is further arranged on the mooring anchor chain.

The novel mooring buoy is further characterized in that the interior of the buoy is divided into 4 areas in an equal space mode to form 4 empty chambers.

The novel mooring buoy is further provided with 1 manhole cover on the surface of the upper deck at the top of each area.

The structure of the invention is more optimized, the stress direction of the system is transmitted along the direction of a quick release hook, a connecting shaft, a lifting lug for connecting an anchor chain, a mooring anchor chain and a mooring cable in a direction close to a straight line, the main stress structure is the structure of the connecting shaft, and the buoyancy generated by the buoy shell is mainly without huge mooring force. Therefore, the weight is effectively reduced while the normal function is ensured, the balance and the stability of the buoy are kept, and the construction cost is saved.

Detailed Description

The invention is further explained with reference to the drawings.

As shown in fig. 3 and 4, the novel mooring buoy has a cylindrical cylinder body 6, a circular upper deck is arranged at the top of the cylinder body, a circular bottom plate is arranged at the bottom of the cylinder body, the upper deck, the cylinder wall and the bottom form an empty cabin inside the buoy, the empty cabin and other spaces inside the buoy are divided into 4 areas, each area is provided with a manhole cover, and the manhole covers are arranged at the upper deck.

At the upper deck edge, be provided with the fan-shaped platform of undercut, be fixed with quick release hook on the platform, quick release hook passes through the release hook base to be fixed on the platform. Inside the flotation pontoon, use the release hook base as the starting point, it has the connecting axle to the diagonal extension, and the welding of connecting axle tip has the lug, and the lug passes the bottom plate. The connecting shaft and the central axis of the bottom plate form an included angle of 45 degrees. The quick release hook is connected with a mooring ship through a mooring anchor chain, the lifting lug is connected with the grabbing anchor through a mooring cable, and the grabbing anchor is fixed on the seabed. And a guide ballast anchor is also fixed between the holding power anchor and the lifting lug and on the mooring cable.

The connecting shaft is the main stressed structure of the buoy, and by adopting the structure with the connecting shaft arranged obliquely, the quick release hook, the mooring anchor chain, the connecting shaft, the mooring cable and the holding power anchor are almost kept on the same straight line (as shown in figure 5) when the buoy is used, the system stress direction is transmitted along the quick release hook, the mooring anchor chain, the connecting shaft, the mooring cable and the holding power anchor in the direction close to the straight line, the buoy mainly generates buoyancy and is not subjected to huge mooring force, the normal function is ensured, meanwhile, the buoy can be kept to be close to the horizontal state and not to be inclined, equipment on a deck on the buoy is prevented from being corroded by seawater, the weight is effectively reduced, and the construction cost is saved.

The barrel body outer surface and the barrel wall are covered with a layer of anti-collision rubber, the anti-collision rubber is arranged along the direction of the barrel body and is attached to the barrel body outer surface, and the effect of protecting the buoy is achieved. A circle of guardrail is arranged along the edge and the circumferential direction of the upper deck.

The novel buoy structure provided by the invention has the advantages that the structure is optimized, the arrangement direction of the connecting shaft is changed under the condition that the buoy body is not changed, the stability of the buoy in the use process is further ensured, and equipment on a deck on the buoy is prevented from being corroded. The normal function is guaranteed, meanwhile, the weight is effectively reduced, and the construction cost is saved.
