An elastic structure anti-impact frame body for use in ships, automobiles, aircraft, trains, railcars and other moving vehicles, said frame body being a wholly or partially elastic frame, the bearing components constituting the frame body forming an arc-shape or a wave-shaped curve, and the frame body being made of an elastic material. The whole or part of the structure of the elastic structure anti-impact frame body has an elastic deformation function; on the premise that the elastic structure does not affect normal driving or bearing capacity, under the force of an impact on said frame, the frame body will elastically deform within a corresponding safe range, and can cushion and absorb the energy of the impact; the frame body, when releasing the energy of the impact, returns to the original shape, greatly improving the anti-impact security factor.

A float for a barrier for a waterway, a waterway barrier including the float, and a method for forming the waterway barrier are provided. The float includes a caseless float body which is formed of a single, homogeneous material. The material may be a high density urethane or a functional equivalent.

The present invention relates to a hull for a water craft. More particularly it relates to an inflatable hull with flexible tension members acting in tension, and extending between the gunnels to aid in maintaining the hull shape in operation.

There is provided an assembleable boat made of fiber-reinforced plastic (FRP) including a bottom wall assembly; a left side wall assembly; a right side wall assembly; and a front wall assembly. the bottom wall assembly, the back wall assembly, the left side wall assembly, the right wall assembly, and the front wall assembly are mechanically connected to form the assembleable boat; and each of the bottom wall assembly, the left side wall assembly, the right wall assembly, and the front wall assembly is made of FRP.

A method of manufacturing a body of a structure includes arranging a plurality of foam components of the body such that each one of the foam components abuts at least one other of the foam components to form a shape. The method also includes applying polyurea along intersection lines of the foam components and covering a surface of the shape, thereby bonding the components together and providing a composite material forming the body of the structure.

There is provided an assembleable boat made of fiber-reinforced plastic (FRP) including a bottom wall assembly; a left side wall assembly; a right side wall assembly; and a front wall assembly. the bottom wall assembly, the back wall assembly, the left side wall assembly, the right wall assembly, and the front wall assembly are mechanically connected to form the assembleable boat; and each of the bottom wall assembly, the left side wall assembly, the right wall assembly, and the front wall assembly is made of FRP.

The present disclosure provides a carrying device and an operation method thereof. The carrying device includes: a floating platform; and at least one flexible unit provided on a bottom side of the floating plate and having a cavity formed therein. The flexible unit is deformed under a stress to reduce the friction force between the flexible unit and the solid in the water, which allows the carrying device to break free from the solid without external help.
