Anchoring body and underwater vacuum anchoring system

Abstract

The invention discloses an anchoring body. The anchoring body comprises a connecting piece which is arranged at the top of the anchoring body and is structurally characterized in that the upper portion of the anchoring body is a solid balance weight body, the lower portion of the anchoring body is of a groove structure with a downward opening, the groove structure is located under the balance weight body and connected with the balance weight body, and the exhaust pipe penetrates through the balance weight body and is communicated with the groove structure. According to the anchoring body, the groove structure is formed in the lower portion of the anchoring body, a vacuum cavity structure is formed in the lower portion of the anchoring body through an underwater waterproof soil body, then the exhausting pipe communicated with the groove structure is connected with external vacuumizing equipment, negative pressure can be formed in the lower groove structure (the vacuum cavity structure), and the anchoring block can be conveniently sunk into the soil body; the horizontal resistance provided by the lateral soil pressure of the soil body is effectively utilized and can be verified through mechanical calculation.

Description

technical field [0001] The invention relates to the field of anchoring systems for floating photovoltaic power plants, in particular to an anchoring body and an underwater vacuum anchoring system. Background technique [0002] Floating photovoltaic power generation projects on water have the advantages of saving land, increasing power generation, protecting water resources, convenient operation and maintenance, reducing costs, and convenient consumption. They have developed rapidly in recent years. The anchoring system is to ensure the safe operation of floating photovoltaic power generation systems Important Guarantee. [0003] There are two types of anchoring systems commonly used at present: pile anchor type and counterweight block type. Among them, the pile-anchor anchorage system uses the pile foundation driven into the water to provide anchoring force. After the operation period of the power station expires, there is a problem that the pile foundation is difficult to ...

AI Technical Summary

Problems solved by technology

Among them, the pile-anchor anchorage system uses the pile foundation driven into the water to provide anchoring force. After the operation period of the power station expires, there is a problem that the pile foundation is difficult to remove; the counterweight anchor system uses the counterweight placed in the bottom of the water to provide anchorage However, the anchoring force that the counterweight can provide is affected by the buoyancy of the water body and the depth of the anchoring block entering the soil. The anchoring force that can be provided is difficult to verify through calculation, and the required counterweight is large in size, which is not conducive to construction and cost control.
