Abstract
The present invention relates to a kind of working fluid measuring and testing device, it is based on infrared sensing principle, on transparent, vertical pipeline, alarm signal is sent when the liquid of circulation in the pipeline can be measured, droplet counting and liquid are flow to end.The tandem product to be transformed of the invention has preferable Social benefit and economic benefit.
Description
(1) technical field
The present invention relates to a kind of working fluid measuring and testing device, specifically this be one kind can convection current by transparent, vertical
Liquid in straight pipeline measured, one after another drop of drop is counted and send when liquid flows to end alarm signal based on
The working fluid measuring and testing device of infrared ray sensing principle.
(2) background technology
In many occasions such as production, life, filling drink, processing industry and cooling, disease are dripped in such as agriculture and forestry drip irrigation, animal husbandry
People's transfusion etc. can all run into liquid circulation or in the way of conveying of being circulated in the form of drop and scene in the transparent vertical pipe, at this
It is necessary to apply upper working fluid measuring and testing device in the case of a little.Done so that patient infusion is cured the disease as an example to illustrate, patient infusion
The typically patient that cures the disease lies on one's sick bed, and infusion bag hanging fills the liquid in bag by defeated in the top of patient
Fluid catheter, syringe needle etc. are passed into the vein blood vessel of patient；When liquid in transfusion catheter will flow to end, show this bag of liquid
Thoroughly conveying is finished, it is necessary to patient, entourage press alarm switch or nurse call to replace infusion bag；If not having
Entourage only patient infuses alone and patient falls asleep again in the case that, such case is just very awkward, the vein of patient
Blood vessel there is also the situation of blood back；If there is entourage to accompany and attend to patient infusion, a main task of entourage is exactly
Liquid conveying in observation infusion bag is over and does not have, and this will consume the more time and larger energy of entourage；If this
A kind of working fluid measuring and testing device, in the case where liquid flows to end, it can automatically send relative alarm signal, and this can band
Come how big social benefit.Equally, in the occasions such as drip irrigation, embedding to working fluid monitoring, monitoring, gauge check
Also it is particularly significant.For this, we investigated a kind of working fluid measuring and testing device.
(3) content of the invention
It is an object of the invention to provide it is a kind of the liquid that is circulated in transparent, vertical pipeline can be counted, measured,
Detection and liquid send the working fluid measuring and testing device of alarm signal when flowing to end.
The present invention is achieved by the following technical solutions：A kind of working fluid measuring and testing device, it is by matrix, red
Outside line transmitter, infrared receiver, the part-structure of circuit four are formed；Its sensing principle is：When in transparent, vertical pipeline
When having drop to pass through or have liquid communication, the infrared ray that RF transmitter is launched is by the drop or the liquid of continuous flow in pipeline
Body is stopped that infrared receiver does not just receive the infrared ray that RF transmitter is launched, therefore circuit has just been generated
The electric signal of drop or liquid communication；When there is no drop or liquid communication in transparent, vertical pipeline, RF transmitter
The infrared ray launched can be received by infrared receiver, circuit can just be produced without drop or liquid communication electric signal and
Relevant action.
As previously described：Transparent, vertical pipeline is the premise for being applicable working fluid measuring and testing device, transparent duct wall
It is suitable for the infrared penetration that RF transmitter is launched；Vertical pipeline ensure that working fluid measuring and testing device is accurate
Ground gauge check monitoring.
As previously described " matrix ", it is wrapped on transparent, vertical pipeline, the internal diameter of matrix with surrounded by it
The external diameter of pipeline is consistent；Matrix is again the carrier of RF transmitter, infrared receiver, circuit part.
" matrix " is opened on matrix and is formed with through through hole as previously described, and the through hole of matrix side is placement infrared emitting
Device and open system, the through hole of matrix opposite side opens system to place infrared receiver；The circuit of correlation is installed on matrix.
RF transmitter, can send the infrared ray not less than 940 nano wave lengths after powered up as previously described, and it can be
LED light emitting diodes, or LD semiconductor lasers.
Infrared receiver as previously described, it is made up of wave filter and photodiode, and the wave filter of its prime can be filtered
Fall visible ray, photodiode can receive the infrared ray that RF transmitter is launched, when having infrared ray, with photosensitive two pole
The circuit of pipe connection is in " logical " state, and during without infrared ray, the circuit being connected with photodiode is in " disconnected " state.
Circuit part as previously described, it is attached on matrix the side for having infrared receiver, and circuit part connects infrared ray
" logical " " disconnected " State Transferring of device is received into corresponding electric signal.
The beneficial effects of the invention are as follows：A kind of working fluid measuring and testing device, it is applied to production, life, science reality
Testing etc. needs to count the liquid flowed in transparent, vertical pipeline in many occasions, measures, detects, monitoring, and promotes
Preferable economic benefit and social benefit can be obtained after.
(4) illustrate
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is structural representation of the invention, and accompanying drawing 1 is also Figure of abstract.
In accompanying drawing 1：1 transparent vertical infrared receiver of the RF transmitter 4 with wave filter of 2 matrix of pipeline 3
The circuit part of device 5.
(5) specific embodiment
As shown in Figure 1, a kind of working fluid measuring and testing device of the invention, the internal diameter of its matrix 2 with it is transparent, vertical
The external diameter of pipeline match, RF transmitter 3 is installed, in the through hole of the opposite side of matrix 2 in the through hole of the side of matrix 2
The infrared receiver 4 of wave filter is provided with, circuit part 5 is installed on matrix 2, it is this after being powered to circuit part 5
Working fluid measuring and testing device just can be with normal work.
Claims (1)
1. a kind of working fluid measuring and testing device, it is characterised in that：The through hole for being formed with right-angled intersection, the water of matrix 2 are opened on matrix 2
The side of flat through hole is provided with RF transmitter 3, and the opposite side of horizontal through hole is provided with the infrared receiver with wave filter
4, circuit part 5 is installed on matrix 2.
