Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
As shown in Figure 1, the present invention discloses a kind of tuned liquid damper, TLD, tuned sloshing damper with earthquake alarm function, comprise tuned liquid damper, TLD, tuned sloshing damper body 1 and early warning circuit, physiological saline 2 is held in tuned liquid damper, TLD, tuned sloshing damper body 1, physiological saline 2 is ordinary water level 6 at the water level of tuned liquid damper, TLD, tuned sloshing damper body 1, early warning water level 5 position needing early warning is set above tuned liquid damper, TLD, tuned sloshing damper body 1, early warning circuit is non-closed circuit, the gap 3 of early warning circuit is arranged on early warning water level 5 position, arrange prior-warning device 4 in early warning circuit, prior-warning device 4 is buzzer or audible-visual annunciator.
Earthquake intensity mark pipe 9 is communicated with tuned liquid damper, TLD, tuned sloshing damper body 1 bottom, form the U-tube be communicated with, physiological saline 2 in tuned liquid damper, TLD, tuned sloshing damper body 1 enters in earthquake intensity mark pipe 9, and earthquake intensity mark pipe 9 upper end early warning water level 5 position starts to paste PH test paper variable color mould 10 upward, identifies scale simultaneously.
Earthquake intensity (seismicintensity) represents the degree of strength that earthquake affects earth's surface and engineering works.(or being interpreted as the degree of earthquake effect and destruction).When there is no instrument record, with the sensation of people during earthquake or the degree of implements reaction after the earthquake, the changing condition on the damage of engineering works or destructiveness, earth's surface and fixed a kind of macro-scale.If give the vibrations degree that tuned liquid damper, TLD, tuned sloshing damper body 1 is different, the amplitude that tuned liquid damper, TLD, tuned sloshing damper body 1 swings height of liquid level that the is different and rising of earthquake intensity mark pipe 9 water level is different.According to each water level peak of PH test paper metachromatic principle record, when different water levels can represent earthquake, the ground in a certain area and all kinds of building are subjected to the degree of strength of one earthquake impact.More refinement, embody this earthquake intensity size more objectively.
