Water photovoltaic anchorage system suitable for large-variation and high-flow-velocity waters and design and construction method of water photovoltaic anchorage system

Abstract

The invention discloses a water photovoltaic anchorage system suitable for large-variation and high-flow-velocity waters and a design and construction method of the water photovoltaic anchorage system. The water photovoltaic anchorage system comprises pipe piles arranged in the waters around a photovoltaic array, wherein the pipe piles are provided with position-limiting pulley assemblies; and theposition-limiting pulley assemblies are connected with steel supports arranged outside the photovoltaic array by anchor ropes. The position-limiting pulley assemblies are arranged at the surface of the pipe piles, so that the anchor ropes which connect the pipe piles with the photovoltaic array are always in the horizontal direction and rise and fall along with the variation of the water level. The water photovoltaic anchorage system is capable of adapting to the large variation of the water level without the need for a large amount of anchor ropes and avoiding instability of the water photovoltaic anchorage system caused by the variation of the water level. The water photovoltaic anchorage system suitable for the large-variation and high-flow-velocity waters has the advantages of uniformstress on a floating body and small vibration and deflection of the photovoltaic array and is applicable to the waters with large variation in the water level and high flow velocity. The water photovoltaic anchorage system can still effectively ensure the overall stability of a water photovoltaic power station under harsh environmental conditions.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, and specifically refers to a water surface photovoltaic anchoring system and a design and construction method suitable for large-variation and high-velocity waters. Background technique [0002] With the large-scale construction of surface photovoltaic power stations in the Lianghuai coal mining subsidence area in China, the stability of floating water surface photovoltaic power stations and the design of their anchoring systems have attracted much attention. At present, the anchoring system of most floating water surface photovoltaic power plants is "imitated by experience" based on the ship mooring system, and there is a lack of reliable calculation basis for both piling anchorage and anchorage anchorage. Most of the anchoring design is to gradually increase the strength of the anchoring system experimentally, or it cannot guarantee the stability of the photovoltaic array ...

AI Technical Summary

Problems solved by technology

The anchor block is subjected to strong wind, wave and current impact in waters with high flow velocity, and it is very prone to anchoring and other situations, which cannot guarantee the stability of the photovoltaic array

The photovoltaic array will rise and fall with the change of the water level, and the photovoltaic array has certain hidden dangers of instability when the water level fluctuates greatly

At present, the existing anchoring system generally adapts to the change of water level by reserving a margin of anchor rope, but too large margin of anchor rope may cause serious deflection and offset of the array, affecting the stability and power generation of the array. If the array spacing is too small, there may even be a collision
