Embodiment Construction

[0036] Below in conjunction with accompanying drawing and embodiment this sensor is described in detail:

[0037] 1. Overall

[0038] Such as figure 1 , the sensor includes a base 101, a first support leg 1021, a second support leg 1022, a third support leg 1023, a moving plate 103, a first fixed plate 1041, a second fixed plate 1042, a suspension wire 105, and a bracket 106 and shell 107, suspension wire fixed adjuster 108, suspension wire shielding tube 109, side position stop screw 110, positive position stop screw 111 and lock pendulum 112;

[0039] The shell 107 and the base 101 are connected up and down to form a closed whole body, and the first support leg 1021, the second support leg 1022, and the third support leg 1023 arranged in an isosceles right triangle are arranged under the base 101;

[0040] A support 106 is provided on the inner wall of the housing 107, a first fixed plate 1041 and a second fixed plate 1042 parallel to each other are respectively provided o...

Abstract

The invention discloses a two-degree-of-freedom earth crust deformation inclination and rotation observation sensor, and relates to an earthquake omen early warning observation technology. The two-degree-of-freedom earth crust deformation inclination and rotation observation sensor is constructed in such a way: a housing and a pedestal are connected in an up-down mode to form an enclosed integral body, and the lower surface of the pedestal is provided with a first support leg, a second support leg and a third support leg which are arranged in the shape of an isosceles right angled triangle; the inner wall of the housing is provided with a support, the two sides of the support are respectively provided with a first fixed pole plate and a second fixed pole plate in parallel, and the center of the top portion of the support is provided with a suspension fiber fixation adjuster; and the suspension fiber fixation adjuster, a suspension fiber and a movable pole plate are successively connected in an up-down mode, and the movable pole plate is disposed between the first fixed pole plate and the second fixed pole plate and is parallel to isosceles edges of the pedestal. The two-degree-of-freedom earth crust deformation inclination and rotation observation sensor has the following advantages: single-point horizontal amount and a rotation amount can be simultaneously measured, the observation frequency band is wide, the dynamic scope is large, and the linearity is good; and change and high-frequency vibration of an Earth tide can be reflected, and change of an earth crust deformation rotation amount can also be observed.

Description

technical field [0001] The invention relates to an earthquake precursor early warning observation technology, in particular to a two-degree-of-freedom crustal deformation tilt and rotation observation sensor. Background technique [0002] Prediction of earthquake precursors is one of the major topics in earthquake research. Successfully predicting the time, place, and size of earthquakes is also a worldwide problem, largely due to the inability to obtain comprehensive, accurate and quantitative information related to earthquake precursors. Crustal deformation measurement is one of the main means for earthquake precursors to predict earthquakes. The physical concept is clear, directly reflects the changes in the crust, and explains the stress and deformation of the crust and the process and end of earthquakes caused by faults. [0003] After entering the 21st century, the country has higher and more specific requirements for earthquake precursor instruments. Among the parame...
