Description
Technical Field
The utility model relates to a boats and ships field of mooring, more specifically say, relate to a mooring arrangement of low range of swaying.
Background
When the ship is moored to the single-point mooring device, the ship is moored to the single-point mooring device through the mooring device; however, when mooring, the mooring device tends to generate large shaking, so that a mooring device with low swing amplitude is urgently needed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a mooring arrangement of low range of swaying, can make moored boats and ships more stable.
In order to achieve the purpose, the utility model adopts the following technical proposal:
a mooring device with low swing amplitude comprises a mooring bracket connected to a ship, mooring legs connected to the mooring bracket, a ballast tank connected to the mooring legs, and a rocker arm, wherein one end of the rocker arm is connected to the ballast tank, and the other end of the rocker arm is connected to a single-point mooring platform;
the ballast tank is a cylinder which is horizontally placed; the ballast tank is divided into a plurality of chambers by a plurality of vertically arranged partition plates which are axially arranged along the ballast tank; each clapboard is provided with a clapboard opening;
ballast liquid is filled in the ballast tank, and the volume of the ballast liquid is 55-95% of the volume of the ballast tank; the level of ballast liquid is above the lowest bulkhead opening on each bulkhead.
Preferably, 1-20 partition plates are arranged.
Preferably, 1-30 partition plate openings are formed in each partition plate.
Preferably, the baffle opening is a circular opening.
Preferably, the baffle opening is plural and symmetrically distributed around the center of the baffle.
Preferably, the top of the ballast tank is provided with a water filling port with a sealing cover and an air exhaust port with a sealing cover.
Preferably, the bottom of the ballast tank is provided with a water outlet with a sealing cover.
The utility model has the advantages that the damping effect of the ballast liquid can be exerted to the maximum extent by injecting 55-95% of the ballast liquid into the ballast tank and arranging the partition plates, thereby greatly reducing the swing degree of the ballast tank and further the whole mooring device, and leading the mooring of the ship to be more stable; in addition, the partition plate can reduce structural stress caused by sloshing of the ballast tank, so that the structure of the ballast tank is more stable, and the operation safety of the rocker arm (which is a soft rigid arm) is ensured.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 5, the mooring device with low swinging amplitude of the present invention comprises a mooring bracket connected to a ship, a mooring leg connected to the mooring bracket, a ballast tank connected to the mooring leg, and a rocker arm having one end connected to the ballast tank and the other end connected to a single point mooring platform; the ballast tank generally has a tendency to rock toward the Y-axis as shown in fig. 3.
The ballast tank is a cylinder which is horizontally placed; the ballast tank is divided into a plurality of chambers by a plurality of vertically arranged partition plates which are axially arranged along the ballast tank; each clapboard is provided with a clapboard opening; 1-20 partition plates are arranged; each partition plate is provided with 1-30 partition plate openings; the baffle opening is circular opening (the trompil shape can also take other shapes such as polygon), and the baffle opening has a plurality ofly and encircles the central symmetrical distribution of baffle.
Ballast liquid is filled in the ballast tank, and the volume of the ballast liquid is 55-95% of the volume of the ballast tank; the level of ballast liquid is above the lowest bulkhead opening on each bulkhead.
The top of the ballast tank is provided with a water filling port with a sealing cover and an exhaust port with a sealing cover; the bottom of the ballast tank is provided with a water outlet with a sealing cover.
During the use, pour into ballast liquid into through the water filling port, owing to have the damping effect of liquid and baffle, can reduce the range of rocking of ballast tank to reduce rocking arm, ballast leg, and then be the range of rocking of boats and ships, make the mooring of boats and ships more stable.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
