Seismic simulation device of fire-protection pipeline system

Abstract

The invention relates to a seismic simulation device of a fire-protection pipeline system. The seismic simulation device comprises a framework, a hanging basket, a mobile positioning mechanism and a seismic wave simulation adjustment mechanism, wherein the hanging basket is arranged on the framework by the mobile positioning mechanism, the seismic wave simulation adjustment mechanism is fixedly connected with a fire-protection pipeline and comprises at least one high-frequency low-load electric cylinder and at least one low-frequency high-load electric cylinder, fixed ends of the electric cylinders both are fixedly connected with a sliding block, the sliding block upwards and downwards move and position relative to a sliding rail at a side surface of the framework under a driving effect ofa power piece, ball hinges are arranged at free ends of the electric cylinders, the ball hinges are fixedly connected with a connection piece, and the connection piece is arranged at the periphery ofa middle part of the fire-protection pipeline. The seismic simulation device of the fire-protection pipeline system, created by the invention can be applicable to seismic simulation of fire-protection pipelines with all specifications at the current stage and is of an important significance to research an actual state of the fire-protection pipeline in earthquake.

Description

Technical field [0001] The invention belongs to the field of earthquake simulation, and particularly relates to an earthquake simulation device for a fire pipeline system. Background technique [0002] According to statistics, there are more than 5 million earthquakes on the earth every year, and there are about 20 earthquakes that can cause serious harm to humans. Disasters caused by earthquakes are mainly divided into direct disasters and secondary disasters. Direct disasters are the primary phenomena of earthquakes, such as earthquake fault dislocation and ground vibration caused by earthquake waves. The main disasters caused are: ground damage, building The destruction of objects and structures, the destruction of natural objects such as mountains; secondary disasters are caused by direct disasters, mainly: fire, flood, poisonous gas leakage, plague, etc. In the earthquake disaster, the loss caused by the primary disaster was 31%, and the loss caused by the secondary disaste...

Problems solved by technology

[0003] Although various countries headed by the United States have done a lot of work on earthquake simulation of building bodies since the beginning of the 20th century, and have also incorporated related designs into their respective building design codes, the mechanical and electrical systems or piping systems caused by building shaking damage, which can easily lead to secondary disasters, such as fire, gas or poisonous gas leakage, explosion, etc.

Especially the fire pipeline system, if the fire pipeline system is damaged after an earthquake, a large amount of fire water or gas fire extinguishing agent will not only fail to reduce the disaster, but will also cause a large amount of water leakage, high-pressure gas explosion and other secondary events. disaster, resulting in secondary damage

At present, although many earthquake simulation devices on the building body have been designed and developed in China to improve the design calculation of the building body structure, there is no relevant research on the fire protection pipeline system to avoid damage caused by earthquakes.
