Description

a pontoon

Technical field

The present invention relates to the technical field of water surface floating structures, and in particular to a pontoon.

Background technique

For water surface floating pontoons, plastic pontoons are usually used, or a layer of outer skin is filled with foam to form a structure that can float on the water surface. Floating islands are usually made up of a number of floating pontoons. For common water surface floating pontoons, when they are used on the water surface, they are usually floating islands composed of single-layer pontoons that float on the water surface. For the pontoons used in floating photovoltaic systems, for the convenience of operation and maintenance or aesthetic considerations, usually the upper surface of the pontoon (the surface above the water surface and facing the sky) is relatively flat, while the lower surface of the buoy (the surface immersed in the water) is processed and manufactured. For convenience, an inverted V-shaped support component is usually provided. That is to say, the upper surface of the pontoon is relatively flat as a whole. Except for some installation holes, mark information and some anti-slip concave and convex settings, the whole can be regarded as a flat surface; while the lower surface of the pontoon usually consists of some concave grooves. Some internal reinforcement structures are formed to support the pontoons. The surface anti-skid structure, internal reinforcement structure, and support structure for related components (such as photovoltaic modules and photovoltaic module installation fixtures) provided on the pontoon are collectively referred to as the functional structure of the pontoon.

Common floating islands are used in inland reservoirs and lakes. The shape of the buoy has little to do with its long-term safety. The shape of the buoy is not the main factor affecting the long-term safety of the floating island. The environmental conditions for floating islands used in offshore floating photovoltaics are very different from those in inland waters. There are usually few aquatic organisms attached to the pontoons in inland waters, and usually only some algae float, which is harmful to the pontoons. The impact of the weight is minimal, but various shellfish, barnacles and algae will quickly attach to the lower part of the floating island in the sea, adding extra weight and resistance to the buoy, reducing the effective buoyancy of the buoy, thereby threatening the structural safety of the buoy. In order to deploy floating photovoltaic systems at sea, it is necessary to regularly clean up the marine organisms attached to the bottom of the pontoons. When cleaning the marine organisms at the bottom of floating islands, whether it is using high-pressure jets or mechanical removal, in order to facilitate cleaning, the flatter the underwater part, the easier it is to Easy to clean up. The shape characteristics of the existing buoy make it difficult to clean the bottom of the buoy with attached marine organisms.

Contents of the invention

In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a buoy with a flat lower surface, which is conducive to the cleaning of marine organisms attached to the lower surface of the buoy.

In order to solve the above technical problems, the present invention adopts the following technical solution: a pontoon including an internal sealed space The cylinder is formed with an upper surface facing the sky, a lower surface opposite the upper surface and immersed in water, and an outer ring surface connecting the outer peripheral edge of the upper surface and the outer peripheral edge of the lower surface. The lower surface is a flat plane, and the pontoon Functional structures are provided on the upper surface.

Preferably, the functional structure of the pontoon includes a downwardly concave structural reinforcing groove and an upwardly protruding structural reinforcing rib formed on the upper surface.

Preferably, the functional structure of the pontoon includes a tapered groove formed on the upper surface.

Preferably, the functional structure of the pontoon includes anti-slip blocks provided on the upper surface.

Preferably, the lower surface is a complete plane without openings.

Preferably, the cylinder is provided with a mounting hole, the mounting hole penetrates the cylinder from the upper surface to the lower surface, and the hole wall of the mounting hole is formed by a downward recess from the upper surface.

Preferably, the float is a blow molded hollow plastic product.

Preferably, the pontoon is a composite structure in which a film wraps a lightweight material, the film forms a cylinder, and the lightweight material is accommodated in an internal sealed space of the cylinder.

Compared with the existing technology, the present invention has significant progress:

The pontoon of the present invention makes the lower surface of the cylinder into a flat surface, and arranges the functional structure of the pontoon on the upper surface of the cylinder. Therefore, the pontoons can be spliced to form a floating island with an overall flat lower surface, which can be used at sea. In the scene, the marine organisms attached to the bottom of the floating island can be easily cleaned, facilitating regular operation and maintenance, effectively reducing the additional marine life load brought by marine organisms, while reducing the resistance load of the floating island, improving the performance and safety of the floating island. Based on this, the use of the buoys of the present invention can also reduce the overall size and cost of the buoys. For a water surface floating photovoltaic project using tens to hundreds of thousands of buoys, the use of the buoys of the present invention can increase the effective buoyancy and Reducing the cost of raw materials and reducing the difficulty and cost of operation and maintenance of bottom sea organism cleanup have very important engineering and economic benefits.
