detailed description

The present invention will be further described below in conjunction with specific examples.

The invention provides a connection mechanism for super large floating bodies on the sea, which includes several telescopic devices connected between super large floating bodies. When the two super-large floating bodies rotate relative to each other in the horizontal plane, all the distributed telescopic systems take the center line as the axis of symmetry, and produce telescopic movements in opposite directions according to the rotation direction of the super-large floating bodies, that is, the telescopic system on one side is under pressure, and the telescopic system on the other side Pulled, play the same buffer role.

Preferably, the telescopic device is a hydraulic device. The telescopic device can also be a simple telescopic rod or the like.

Further preferably, as shown in Figures 1 to 6, the two super-large floating bodies are the first floating body 3-1 and the second floating body 3-2, and the hydraulic device includes a piston connected to the first floating body 3-1 Rod 5, the cylinder body 2 fixedly connected with the second floating body 3-2, the front end of the cylinder body 2 is provided with the piston 7 fixedly connected with the piston rod 5, and the rear end of the cylinder body 2 is connected with a cylinder extending to the outside of the second floating body 3-2. Liquid pipeline 10.

Further preferably, the liquid pipeline 10 is provided with an impeller set 1 , the second floating body 3 - 2 is provided with a generator 8 , and the impeller set 1 is connected to the generator 8 . When the water flow passes, a part of the energy of the floating body movement can be converted into electrical energy.

The second floating body 3-2 includes a suspension platform 11, a floating tank 6, and a column 4 for connecting the suspension platform 11 and the floating tank 6, and the cylinder body 2 is fixed in the suspension platform 11 of the second floating body 3-2.

Further, the connection between the piston rod 5 and the first floating body 3-1 is a ball hinge.

Further preferably, it also includes a buffer device arranged on the side of the super-large floating body. The excess energy of the super-large floating body will be absorbed by the buffer device between the super-large floating bodies to protect the super-large floating body module. In this embodiment, the buffer device is a rubber block 9, which can be realized with waste tires or the like.

When the first floating body 3-1 moves towards the second floating body 3-2 under the action of wind, wave and current, the piston rod 5, which is hinged by the ball on the first floating body 3-1, moves accordingly, pushing the water in the cylinder body 2 to flow to the right, As the diameter of the cylinder body becomes smaller and the water in the cylinder body 2 flows out continuously, the flow rate of the water flow increases gradually, and the resistance received by the piston rod 5 becomes larger and larger, thereby hindering the movement of the first floating body 3-1 to the second floating body 3-2. continued movement. Since this resistance is generated due to the restriction of fluid flow, it can be regarded as flexible resistance, and no rigid collision will cause damage to the piston rod. The leftward and rightward movement of the piston rod 5 relative to the second floating body 3-2 will cause the water flow in the liquid pipeline 10 to flow at a high speed, and the impeller group 1 installed in the liquid pipeline 10 and the generator 8 on the second floating body 3-2 will The kinetic energy when the water flows is converted into electric energy for the electricity consumption of the second floating body 3-2.

The ultra-large floating body described in the present invention is a floating body with a length and a width of a kilometer or more used in the sea, and is usually used for replenishment and rescue of ships operating in deep seas.

The above embodiments are only used to illustrate the design concept and characteristics of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The protection scope of the present invention is not limited to the above embodiments. Therefore, all equivalent changes or modifications based on the principles and design ideas disclosed in the present invention are within the protection scope of the present invention.
