Description

Technical Field

[0001] The present invention relates to the technical field of floating bodies on water, and in particular to a multi-module floating body and a preparation method and application thereof. Background Art

[0002] In recent years, the relatively flat land resources are becoming less and less. Photovoltaic power stations usually need to occupy a large area of ​​flat land. However, land resources are very precious in many parts of the country, especially flat land resources, which greatly restricts the construction of photovoltaic power stations. Making full use of water resources to develop photovoltaic power stations has become increasingly popular among local governments. Water photovoltaic power generation is to use idle water surfaces to build photovoltaic power stations, such as abandoned ponds, collapsed areas, muddy grasslands or undeveloped wetlands. Water photovoltaic power stations have many advantages such as not occupying land resources, reducing water evaporation, and avoiding algae growth, and have broad development prospects. During the construction of water photovoltaic power stations, a floating platform on the water is required as a construction platform. The commonly used floating platform on the water is a buoy-type floating platform on the water. The size of the buoy is generally customized according to the size of the equipment. Equipment of different weights requires buoys with different buoyancy. Customized buoys cannot be compatible with a variety of equipment of different weights and sizes. This leads to the inability to mass-produce buoys, high production costs, low construction efficiency, and a large workload for connection and installation.

[0003] In addition, in flood relief or other water work, it is also necessary to build a temporary floating bridge on the water. In some areas with heavy rainfall, temporary floating bridges are also needed as passages to pass through muddy ground. The construction of such temporary floating bridges requires people to soak in water for a long time. The construction process is labor-intensive and the working environment is dangerous. Moreover, the built floating bridge is easily washed across or broken by water, causing life-threatening and economic losses. Summary of the invention
