Abstract
The utility model relates to the technical field of vibration sensors, in particular to a water light vibration sensor for detecting vibration by utilizing water and light. Light emitted by a laser generator of the sensor is reflected by a water surface, reflection light irradiates a photoelectric tube, and the photoelectric tube transmits a light signal to a circuit module for processing; when no vibration exists, the circuit module outputs a stable low level signal; and the water surface generates surface wave and the reflection light is deviated after the sensor is influenced by a vibration signal, the photoelectric tube detects the deviation of light, and the circuit module outputs a square wave signal to enable a vibration indicating lamp to glitter. The sensor can detect micro vibration, has the advantages of simple structure, high sensitivity, difficult damage, low fabrication cost and the like, and can meet various requirements of industry, safety monitoring and scientific research.

Embodiment
The utility model provides a kind of water light shock sensor, below in conjunction with the drawings and specific embodiments the utility model is described further.
As depicted in figs. 1 and 2, the structure of this sensor is: water storage case 2 is positioned at lower house 12 tops, and both are fixed on the base 1 in the one-piece construction mode; Being shaped as rectangle and being inverted trapezoidal combination of water storage case 2, the angle of being inverted trapezoidal two hypotenuses and surface level is 60 °, and at water storage case 2 tops water inlet 5 is set; In lower house 12, two hypotenuse positions of water storage case 2 install laser generator 3 and photoelectric tube 7 respectively, and laser generator 3 two hypotenuses with water storage case 2 are vertical respectively with photoelectric tube 7; Built-in standby power supply 4 and circuit module 8 are installed in lower house 12, and wherein, built-in standby power supply 4 is connected with laser generator 3, circuit module 8 respectively, and circuit module 8 is connected with photoelectric tube 7, signal analyse block 9 and external power source 10 respectively; Adjustable feet 11 is installed on the base 1.
When this sensor uses, inject water 6 to water storage case 2, open laser generator 3 by water inlet 5, by regulating water surface elevation, make the reflection of light that laser generator 3 sends, reflex on the photoelectric tube 7, by photoelectric tube 7 receiving optical signals and output to circuit module 8 through flow surface.
Under the working sensor state, when not detecting vibration signal, the light that laser generator 3 sends is after the total reflection of flow surface, shine on the photoelectric tube 7, after circuit module 8 processing, obtain stable low level signal, the vibrations pilot lamp on the circuit module 8 is in the state that extinguishes.After sensor is given a shock effect of signals, the water surface produces external waviness, make reflection ray be offset, less external waviness just can be that reflection ray produces bigger skew, this moment, photoelectric tube 7 detected the skew of light, obtained a square-wave signal after handling through circuit module 8, made and shook the pilot lamp flicker, simultaneously square-wave signal is outputed to signal analyse block 9, carry out subsequent treatment.
The adjustable feet 11 of regulating on the base 1 gets final product the luminous point of accommodation reflex light and the area that overlaps of photoelectric tube 7, thereby regulates sensitivity.
This sensor also is provided with built-in standby power supply 4 under the situation of using external power source 10, to guarantee that sensor can all can use under all states.
