Abstract
The invention belongs to the field of electronic measurement technologies, and particularly provides a laser-based liquid level warning device which comprises a pipe (1), a laser transmitter (2), a laser receiver (3), a telescopic rod (4), a sliding bolt (5) and a suspension (6). The laser-based liquid level warning device has the advantages that the laser-based liquid level warning device can be inserted in liquid and can be communicated with the liquid owing to holes in the pipe, the liquid level consistency of the laser-based liquid level warning device and the liquid can be guaranteed, and the suspension can float at the liquid level; laser light which is transmitted to the laser receiver by the laser transmitter can be shielded by the suspension when the liquid level reaches set limit, laser signals cannot be received by the laser receiver at the moment, accordingly, the alarm can be started, and users can be reminded.
Description
Technical field
The invention belongs to electronic measuring technology field, specifically provide a kind of liquid level prior-warning device based on laser, the level gauging of multiple occasion can be adapted to, when reaching the setting limit, start and report to the police, easy to use.
Background technology
The measurement of liquid level has very large demand in real life, be no matter for the level gauging of nontransparent device or for other for ensureing that safety does not allow liquid level to exceed for the occasion of certain limit, measure and have very important meaning with early warning.
Now liquid level gauge kind is commercially many, generally also comprise float, radar, ultrasound wave etc. metering system, these metering systems are in order to reach higher measuring accuracy, often need loaded down with trivial details physical construction and the cost of great number, and in life, in a lot of situation, we do not need very accurately to measure liquid level, only need to be pointed out just when liquid level reaches early warning height.
For this situation, the invention provides a kind of liquid level prior-warning device based on laser, comprise conduit, generating laser, laser pickoff, expansion link, sliding bolt, suspended matter, device is inserted in liquid, due to conduit having hole, can realize being communicated with liquid, both guarantees liquid level is consistent, meanwhile, suspended matter can swim in liquid level; When liquid level reaches the limit of setting, suspended matter can block the laser of laser transmitter projects to laser pickoff, now, laser pickoff does not receive laser signal, starts alarm, reminding user, its essence is also float-type measuring method, but the rectilinearity that make use of laser is good, reduces cost, different containers and liquid can be adapted to simultaneously.
Summary of the invention
The object of the invention is to overcome complex structure in prior art, problem that cost is high.
For this reason, the invention provides a kind of liquid level prior-warning device based on laser, comprise conduit, generating laser, laser pickoff, expansion link, sliding bolt, suspended matter, wherein: conduit is the glass tube of hollow, and hole is arranged at bottom; Expansion link is fixed on sliding bolt, and generating laser is fixed on the left end of expansion link, and laser pickoff is fixed on the right-hand member of expansion link; Sliding bolt is fixed on conduit, can slide along conduit; Suspended matter is placed on the inside of conduit; Generating laser and laser pickoff are just right in the same horizontal line.
Above-mentioned a kind of liquid level prior-warning device based on laser, described suspended matter can arbitrarily slide in conduit, floats on liquid level during work.
Above-mentioned a kind of liquid level prior-warning device based on laser, described expansion link can extend and shorten, to adapt to the container of different size.
Above-mentioned a kind of liquid level prior-warning device based on laser, described conduit has scale.
Above-mentioned a kind of liquid level prior-warning device based on laser, described laser pickoff end has alarm.
Above-mentioned a kind of liquid level prior-warning device based on laser, described generating laser 2 end has battery, and is connected with laser pickoff 3 end.
Beneficial effect of the present invention: a kind of liquid level prior-warning device based on laser, comprise conduit, generating laser, laser pickoff, expansion link, sliding bolt, suspended matter, device is inserted in liquid, due to conduit having hole, can realize being communicated with liquid, both guarantees liquid level is consistent, and meanwhile, suspended matter can swim in liquid level; When liquid level reaches the limit of setting, suspended matter can block the laser of laser transmitter projects to laser pickoff, now, laser pickoff does not receive laser signal, start alarm, reminding user, the rectilinearity that make use of laser is good, reduce cost, different containers and liquid can be adapted to simultaneously.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of liquid level prior-warning device based on laser of the present invention.
Description of reference numerals: 1, conduit; 2, generating laser; 3, laser pickoff; 4, expansion link; 5, sliding bolt; 6, suspended matter; 7, hole.
Embodiment
As the structural representation that Fig. 1 is a kind of liquid level prior-warning device based on laser, comprise conduit 1, generating laser 2, laser pickoff 3, expansion link 4, sliding bolt 5, suspended matter 6, wherein, conduit 1 is the glass tube of hollow, and hole 7 is arranged at bottom; Expansion link 4 is fixed on sliding bolt 5, and generating laser 2 is fixed on the left end of expansion link 4, and laser pickoff 3 is fixed on the right-hand member of expansion link 4; Sliding bolt 5 is fixed on conduit 1, can slide along conduit 1; Suspended matter 6 is placed on the inside of conduit 1; Generating laser 2 is just right in the same horizontal line with laser pickoff 3.
Suspended matter 6 can arbitrarily slide in conduit 1, floats on liquid level during work.Expansion link 4 can extend and shorten, to adapt to the container of different size.Conduit 1 there is scale.Laser pickoff 3 end has alarm.Generating laser 2 end has battery, and is connected with laser pickoff 3 end.
During work, first by the length of adjustment expansion link 4, device is made to adapt to container; Unclamp sliding bolt 5, the scale of early warning is set, fixing sliding bolt 5; Open generating laser 2, slowly put in container by device, fixing, now, in container, inject liquid, if liquid exceedes early warning height, laser pickoff 3 will be reported to the police.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
