Technical Field

The invention relates to the technical field of water surface floating, in particular to a buoy.

Background

In the industries of water surface photovoltaics, water surface floating wharfs and the like, a plastic buoy is usually adopted as a water surface floating buoy, and the large-size plastic buoy is formed by blow molding in a conventional processing method. For blow-molded pontoons, the manufacturing process dictates that no support structure can be added to the interior of the pontoon. If the flotation pontoon is longer, thickness is great, does not increase corresponding bearing structure if the flotation pontoon is inside, then flotation pontoon overall structure can be softer, and the flotation pontoon is used for providing the condition of bearing, and the face that the flotation pontoon atress has great deformation, can be shriveled by the pressure very likely, causes the structural instability, influences its service function, can't satisfy the in-service use requirement. In order to improve the actual overall rigidity of the buoy, the blow-molded buoy generally adopts a structure that a support structure with an inverted V-shaped cross section is arranged on the back surface and is propped against the surface of the opposite buoy, namely, the back surface of the buoy extrudes a skin into the interior of the buoy during blow-molding, so that the support structure reaching the wall surface of the opposite buoy is formed, and the overall strength and rigidity of the buoy are improved. However, the reverse V-shaped structure is adopted on the back of the pontoon, so that the corresponding problems are caused, the first problem is that the effective volume of the pontoon is reduced, and the second problem is that the reverse V-shaped structure exists, and more additional raw materials are used.

Preferably, the cross-sectional area of the waisted hole becomes gradually larger from the middle of the waisted hole to both ends of the waisted hole.

Preferably, the waisted aperture is located on the surface of the top wall at an aperture cross-sectional area no more than 5% of the surface area of the top wall.

Preferably, the waisted aperture is located on the surface of the base wall at an aperture cross-sectional area no more than 5% of the surface area of the base wall.
