Embodiment Construction

[0013] Such as figure 1 As shown, the liquid fluctuation sensing vibration measuring device of the present invention includes a container 1, an inner cylinder 6, a conductive solution 5, a base electrode 2, a sensing electrode 3, a control unit 8 and an alarm unit 4; Inside, it is coaxial with the container 1, and the inner cylinder 6 and the container 1 are fixed and sealed at the bottom. A conductive solution 5 is installed between the inner cylinder 6 and the container 1 . The top of the conductive solution 5 is sealed with a transparent cover 7 to prevent evaporation and loss of the conductive solution and corrosion to the circuit. Because seismic waves may come from any horizontal direction, and a circle is the most symmetrical geometry, a cylindrical inner cylinder was chosen. The copper wires used as the base electrode 2, the first-level sensing electrode 31, the second-level sensing electrode 32, and the third-level sensing electrode 33 are sequentially wound on the ...

Abstract

The invention relates to a liquid fluctuation sensing vibration measurement device. The inner barrel of the device is placed in a container and is coaxial with the container; conductive solution is held between the inner barrel and the container; base electrodes and sensing electrodes are a group of parallel fine wires which are sequentially wound on the outer wall of the inner barrel, and the base electrodes are immersed in the conductive solution all the time; the sensing electrodes and the base electrodes are respectively connected with the input of a control unit, and the output of the control unit is connected with an alarm unit; priority trigger level is set by the control unit, the control unit preferentially triggers the interface connected with the sensing electrode which is the highest, and transfers graded signals to the alarm unit; and the alarm unit gives out graded alarm signals indicating earthquakes with different intensities according to the received graded alarm signals. The measurement device has good reliability and repeatability, simple structure, small volume, low cost, energy conservation and environmental protection, can realize graded alarm to earthquakes with different intensities, and can remind people to transfer or hide in time when earthquake just begins, thereby reducing casualties.

Description

technical field [0001] The invention relates to an earthquake alarm device, in particular to a liquid fluctuation sensing vibration measuring device. Background technique [0002] Seismic waves are elastic waves that radiate outward from the source. Seismic waves are divided into three types according to the propagation mode: longitudinal wave, shear wave and surface wave. At the epicentre, longitudinal waves jolt the ground up and down. Shear waves make the ground shake horizontally, so places farther from the epicenter often do not feel the up and down jumps, but can feel the horizontal shaking. [0003] Earthquake alarm is a means to remind people to take evasion measures as soon as possible when the earthquake wave has arrived, and it is a remedial measure after earthquake forecast or early warning. When an earthquake occurs, people often don't immediately realize that it is an earthquake. And hesitation and delay in judgment at critical moments will lose valuable he...
