The laser liquid level detection device disclosed by the utility model can be installed on the transparent pipeline, and used for realizing automatic control on the liquid level of a liquid in the transparent pipeline, and is especially suitable for the cases that liquid levels are not easy to measure by contact, for example, measurements for the liquid levels of high-temperature, high-pressure and strong-acid-base liquids in transparent pipelines. The device is simple and easy to use, convenient to install, and beneficial to realize automatic control.
Description
Technical field
The utility model relates to a kind of transparent pipeline laser liquid-level measurement device.
Background technology
In prior art, a lot of liquid level containers have visual transparent pipe liquid level gauge, particularly be not easy to the situation of contact measurement liquid level, as the measurement of the transparency liquid of high temperature, high pressure and strong acid-base liquid level in transparent pipe, need especially a kind of special liquid level detection device.Based on this, the inventor develops a kind of transparent pipeline laser liquid-level measurement device, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of transparent pipeline laser liquid-level measurement device, and it is simple and easy to use, installs easily, is conducive to realize robotization and controls.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of transparent pipeline laser liquid-level measurement device, by modulated laser source and modulated laser receiver, formed, modulated laser source and modulated laser receiver are arranged on respectively the both sides of transparent pipeline, and the laser beam of modulated laser source transmitting is an angle from bottom to top and with the axis of transparent pipeline.
Described modulated laser receiver has guide rod and laser pick-off head, and laser pick-off head is arranged on guide rod in the mode that can slide up and down.
Described guide rod is screw rod, on laser pick-off head, forms screw, by screw rod, coordinates with screw, and laser pick-off head can be slided up and down and locate on guide rod.
Adopt after such scheme, when the utility model is used, the laser beam of modulated laser source is slanted through (direct projection does not have refraction angle) in pipeline through transparent pipeline axis, because the refractive index of laser beam is not different when there is no liquid when pipeline has liquid, so, the deflecting light beams that produces when having liquid of laser beam of transmitting or total reflection light beam and the light beam while not having liquid can be beaten the diverse location at pipeline opposite side modulated laser receiver, by detecting the laser beam of different times, just can tracer liquid liquid level whether arrive detected locating.
The utility model can be installed on transparent pipeline, for realizing robotization, controls transparent pipeline liquid level, is specially adapted to be not easy to the situation of contact measurement liquid level, as the measurement of the liquid of high temperature, high pressure and strong acid-base liquid level in transparent pipeline.This device is simple and easy to use, easy for installation, is conducive to realize robotization and controls.

Fig. 2 is structural representation of the present utility model (liquid level is low);
Fig. 3 is the side view of the utility model modulated laser receiver.
Label declaration
Modulated laser source 1, modulated laser receiver 2, guide rod 21, laser pick-off 22, transparent pipeline 3, liquid level 31.
Embodiment
As shown in Figure 1 to Figure 3, a kind of transparent pipeline laser liquid-level measurement device that the present invention discloses, is comprised of modulated laser source 1 and modulated laser receiver 2.Modulated laser source 1 and modulated laser receiver 2 are arranged on respectively the both sides of transparent pipeline 3.The laser beam of modulated laser source 1 transmitting from bottom to top, and is an angle (direct projection does not have refraction angle, and corner dimension is not) with the axis of transparent pipeline 3.Modulated laser receiver 2 has guide rod 21 and laser pick-off 22, and laser pick-off 22 is arranged on guide rod 21 in the mode that can slide up and down.For convenient, regulate and locating laser Receiver 22, guide rod 21 can adopt screw rod, in laser pick-off 22, forms screw, by screw rod, coordinates with screw, and laser pick-off 22 can be slided up and down and locate on guide rod 21.
When the utility model is used, the laser beam of modulated laser source 1 is slanted through in pipeline through transparent pipeline 3 axis.As shown in Figure 1, in transparent pipeline 3, during no liquid, laser beam penetrates through transparent pipeline 3 along dotted line; While having liquid and liquid level high in transparent pipeline 3, laser beam enters in transparent pipeline 3 along solid line, the deflecting light beams producing in liquid, then pass transparent pipeline 3 and reflect away.As shown in Figure 2, while having liquid and liquid level low in transparent pipeline 3, laser beam enters in transparent pipeline 3 along solid line, the deflecting light beams producing in liquid, then produce total reflection light beam at liquid level 31 places, finally pass transparent pipeline 3 and reflect away.
The utility model because transparent pipeline 3 while having liquid when there is no liquid the refractive index of laser beam different, laser beam issuable deflecting light beams or total reflection light beam when having liquid of transmitting, the light beam producing when not having liquid can be beaten the diverse location at transparent pipeline 3 opposite side modulated laser receivers 2, like this, by detecting the laser beam of different times, just can tracer liquid liquid level whether arrive detected place.
The utility model application of modulation lasing light emitter 1, laser concentration is good, through the laser cooperation modulated laser receiver 2 of ovennodulation, can avoid other light sources impact, and reliability is high; By regulating the position of laser pick-off 22, can adapt to various refractive index liquid and various sizes pipeline.
