Compound damping and limiting device for horizontal-direction friction viscosity of photovoltaic power station

Abstract

Disclosed is a compound damping and limiting device for horizontal-direction friction viscosity of a photovoltaic power station. The compound damping and limiting device is arranged between a foundation and an upper structure bottom plate, a slideway is fixed on the upper structure bottom plate, a friction unit is embedded into the slideway to be capable of sliding freely in a direction perpendicular to the friction force, the friction unit and the foundation are fixed by sway braces, and one ends of additional oil dampers are connected with concrete piers of an upper structure through spherical hinges. The compound damping and limiting device for horizontal-direction friction viscosity of the photovoltaic power station has the advantages that the problem of secondary destruction caused by pipeline fracture resulting from overlarge photovoltaic power station isolating layer displacement under the action of moderate and small earthquakes is solved, and the device starts to slide under the action of large earthquakes to consume earthquake energy as a friction damper.

Description

technical field [0001] The invention relates to the field of shock absorption of building structures, which is used for shock absorption and isolation of structures sensitive to the displacement of shock-isolation layers. Background technique [0002] As a renewable energy source, solar energy has multiple advantages such as cleanliness, safety, durability and potential economy, and has an important strategic position in the national energy field. The available total amount of water energy, wind energy, tidal energy, etc. is small, and the existing technical level cannot meet human needs. Although the energy produced by nuclear energy is huge, there are problems of uncontrollability and potential safety hazards. Geothermal energy also has theoretical potential, but there are technical challenges. Therefore, solar energy is an effective clean and safe energy that can be used at this stage and can solve the needs of human beings in the future. [0003] As an important means...

Problems solved by technology

[0004] The site selection of solar photovoltaic power plants is generally located in areas with sufficient sunlight, and many of them are located in plateaus and other earthquake-prone areas. The application of photovoltaic nuclear power plants is of great significance, but the excessive displacement of the isolation layer causes the pipelines entering and leaving the power station to break, which is easy to cause secondary damage. Therefore, the horizontal friction-viscous composite damping limit device of this photovoltaic power plant is developed to solve its application. Key Issues to be Solved
