Segmented type cylinder body applied to high-rise tower frame and swinging shock attenuation device connected with cylinder body

Abstract

The invention discloses a segmented type cylinder body applied to a high-rise tower frame and a swinging shock attenuation device connected with the cylinder body. A wind power generation tower frameis formed by connecting multiple segments of tower frame cylinder bodies (4) through flange joints (3). A cylinder body connecting unit is formed at each joint of two cylinder bodies. Each cylinder body connecting unit comprises an upper segment cylinder body (11), an upper segment cylinder body connecting flange (12) integrally connected with a corresponding upper segment cylinder body (11), a lower segment cylinder body (16) and a lower segment cylinder body connecting flange (17) integrally connected with a corresponding lower segment cylinder body (16). By means of the swinging shock attenuation device, when an earthquake happens, pre-tightening interfaces between segmented type cylinder bodies are separated, and swinging movement is generated. The swinging shock attenuation device issimple and efficient, novel in structure, easy to install, convenient to maintain and safe and reliable; and shock resistant capacity of high-rise tower frames such as the wind power generation towerframe and the like can be improved effectively.

Description

technical field [0001] The invention relates to a sway shock absorbing device connected to a high-rise tower barrel, in particular to a sway shock absorber applied to a segmented barrel of a high tower and connected to the barrel. Background technique [0002] As a clean renewable energy, wind power has significant social and environmental benefits, and is of great significance to promoting the development of renewable energy in my country. The state supports and encourages the development of wind power. my country is rich in wind resources. According to the statistics of the National Meteorological Administration, the national wind energy density in my country is about 100W / m 2 , the wind energy resource reserve is about 1.6x10 5 MW, great development potential. At the same time, my country is also an earthquake-prone country. From attached figure 1 China's effective wind power density distribution map and attached figure 2 Comparing my country's peak ground accelerat...

Problems solved by technology

Moreover, this damping scheme has no rocking mechanism. The vibration isolation device formed by the metal pressure ring 7 and the metal rubber sleeve 5 is not a variable stiffness unit. This damping scheme cannot dissipate the input energy of the earthquake through the local collision accompanied by the reciprocating rocking motion. This scheme also has limited ability to reduce the seismic response of the superstructure of the tower and ensure the safety of the superstructure during an earthquake
