Brief description of the drawings
Fig. 1 is cross-sectional view of the invention.
Fig. 2 is cut-away section structural representation of the present invention.
Wherein：1 housing, 2 pendulum masses, 3 pulling ropes, 4 spring wires, 5 support rings, 6 foil gauges, the vertical piece of 7 elasticity, 8 annular seatings, 9
Transverse arm, 10 batteries, 11 controllers, 12 electrical stores, 13 antennas.
Specific embodiment
Further detailed description is done to the present invention below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, a kind of seismic detector for detecting rotation earthquake motion of the invention, including cylinder and the housing of closing
1, the inwall of housing 1 middle part is provided with the support ring 5 of annular, and center vertical is provided with the pendulum mass 2 of cylinder, pendulum in support ring 5
Pass through drawing between the top center of body 2 and the top center of housing 1 and between the bottom centre of pendulum mass 2 and the bottom centre of housing 1
Rope 3 is connected, and uniformly spring wire 4 is connected between the side wall of pendulum mass 2 and support ring 5, and the internal upper part of housing 1 is provided with transverse arm 9, transverse arm
9 ends are connected with annular seating 8, and two rectangular vertical pieces 7 of elasticity, two are connected between the bottom of annular seating 8 and the top of pendulum mass 2
Plane where foil gauge 6, and two vertical pieces 7 of elasticity are posted on the vertical piece 7 of elasticity is orthogonal, the top center of pendulum mass 2 with
Through the center of annular seating 8, foil gauge 6 is connected with battery 10 and controller 11 to pulling rope 3 between the top center of housing 1.
The top of housing 1 is provided with electrical store 12, and battery 10, controller 11 are arranged on the center of electrical store 12, controller 11
Radio communication unit is connected with, radio communication unit is connected with antenna 13, and antenna 13 is arranged on the top center of electrical store 12.Pendulum mass
2 middle part is highly identical with support ring 5, and support ring 5 is evenly arranged with three fixing points, each fixing point and the side wall of pendulum mass 2
Between be connected with two spring wires 4, two spring wires 4 are symmetrical above and below, and a spring wire 4 extends obliquely, and another is oblique
Extend downwardly.
Its operation principle is：Rotation earthquake motion is the ripple propagated due to deformation of media occurred in unlimited medium
It is dynamic.When being arrived due to earthquake, ground motion includes translation and rotation, uniform due to spring wire 4 in order to avoid the interference of translation
The translation of pulling force ground will not cause pendulum mass 2 to rotate, but the rotation on ground can make the rotation of pendulum mass 2, and pendulum mass 2 is rotating displacement
When the vertical piece 7 of elasticity can be distorted so that there is the change of resistance etc. in the foil gauge 6 being attached on the vertical piece 7 of elasticity, and
Controller 11 is transmitted a signal to, controller 11 extrapolates the size of moment of torsion according to the change such as resistance, derives turning for pendulum mass 2
Angle, so as to further derive the size of rotation earthquake motion.Can be detected simultaneously using the vertical flexure strip of plane where two
Torsion onto two dimensions, detection more comprehensively, and takes both average value, makes testing result more accurate.Calculate
Result backstage is sent to by radio communication unit and antenna, carry out real-time detection.
Because pendulum mass is held about 2 with pulling rope 3, so rotary inertia and spring of the equation of motion of pendulum mass 2 by pendulum mass 2
The righting moment and damping torque of silk 4 are determined.So the equation of motion of pendulum mass 2 is：；In formula,θ
Corner for pendulum mass 2 relative to housing 1,JIt is the rotary inertia of pendulum mass 2,BIt is damped coefficient,CIt is righting moment coefficient, its shape
In formula with level of displacement put the equation of motion be the same, simply lacked gravity righting moment this, it unlike horizontal pendulum both
Rotation around vertical axis can be recorded, but only record rotating part with recording level displacement again.
The above is only the preferred embodiment of this patent, it is noted that for the ordinary skill people of the art
For member, on the premise of the art of this patent principle is not departed from, some improvement and replacement can also be made, these improve and replace
Also should be regarded as the protection domain of this patent.
