Pendulum type three-dimensional vibration acceleration sensor

Abstract

The invention relates to the technical field of acceleration sensors and particularly relates to a pendulum type three-dimensional vibration acceleration sensor. The pendulum type three-dimensional vibration acceleration sensor comprises a shell, a sphere and a rope body, wherein the ball body and the rope body are both arranged in the shell, one end of the rope body is connected with the top of the interior of the shell, the other end of the rope body is connected with the ball body, an inner surface of the shell is plated with an electrode material, the ball body is a charged charged ball body, and the material of the ball body is different from that of the electrode material. The pendulum type three-dimensional vibration acceleration sensor is advantaged in that vibration energy of instrument vibration is converted into electric energy, an auxiliary power supply does not need to be carried, use is more convenient, a vibration state of the instrument can be monitored at the same time, and stability is better.

Description

technical field [0001] The invention relates to the technical field of acceleration sensors, in particular to a pendulum-type three-dimensional vibration acceleration sensor. Background technique [0002] As one of the most common phenomena in nature, vibration exists in everything from the universe to particles. All forms of physical phenomena, including sound, light, heat, etc., contain vibrations. People cannot live without vibration: the beating of the heart, the vibration of the eardrum and the vocal cords are all indispensable functions of the human body; human vision depends on the stimulation of light, and light is essentially a kind of electromagnetic vibration; life cannot be without sound And music, and the production, transmission and reception of sound are inseparable from vibration. In the field of engineering technology, vibration phenomena abound. For example, the vibration of bridges and buildings under the excitation of gusts or earthquakes, the vibratio...

Problems solved by technology

In the Chinese patent CN106500833A, a spaceborne vibration monitoring device based on a vibration sensor is disclosed. The batteries of the vibration sensor in this device all need external circuits for power supply, so they need to be replaced in a short period of time, which greatly increases the cost of monitoring

At the same time, if using cables for power supply will undoubtedly make the whole monitoring system cumbersome and increase the instability of monitoring
