Abstract

The utility model relates to a liquid measurement detection device flows, it is based on infrared sensing principle, installs on transparent, vertically pipeline, can measures, sends alarm signal to the liquid of circulation in this pipeline when flowing to end liquid drop count and liquid. This patent can change the tandem product that forms and have better social and economic benefits.

Description

A kind of working fluid measuring and testing device
(1) technical field
This utility model relates to a kind of working fluid measuring and testing device, and specifically this is a kind of convection current can to carry out measuring, one after another drop of drop be counted and sends when liquid flows to end the working fluid measuring and testing device based on infrared ray sensing principle of alarm signal by the liquid in transparent, vertical pipeline.
(2) background technology
In many occasions such as production, life, drip drink, processing industry fill and cooling, patient infusion etc. such as agriculture and forestry drip irrigation, animal husbandry all to run into liquid and circulate in transparent vertical pipe or in the way of the form of drop circulates conveying and sight, it is necessary in these cases apply working fluid measuring and testing device.Curing the disease for patient infusion and do to illustrate, the patient infusion typically patient that cures the disease lies on one's sick bed, and transfusion bag is hung above patient, fills in the vein blood vessel that the medicinal liquid in bag passes into patient by transfusion catheter, syringe needle etc.;When medicinal liquid in transfusion catheter is about to flow to end, it was shown that this bag of medicinal liquid is thoroughly carried complete, it is necessary to patient, entourage press alarm switch or nurse call to replace transfusion bag;If when not having entourage to only have patient to infuse alone and patient falls asleep again, this situation is just very awkward, and the vein blood vessel of patient there is also the situation of blood back;If there being entourage to accompany and attend to patient infusion, a main task of entourage is exactly that the medicinal liquid conveying observed in transfusion bag is over and does not have, this more time that will consume entourage and bigger energy;If there being so a kind of working fluid measuring and testing device, when medicinal liquid flows to end, it can send relative alarm signal automatically, and how big this can bring social benefit.Equally, in the occasion such as drip irrigation, embedding, the monitoring of working fluid, monitoring, gauge check is also particularly significant.For this, we investigated a kind of working fluid measuring and testing device.
(3) utility model content
The purpose of this utility model is to provide a kind of working fluid measuring and testing device that the liquid of circulation in transparent, vertical pipeline can count, measure, detects and send when liquid flows to end alarm signal.
This utility model is achieved through the following technical solutions: a kind of working fluid measuring and testing device, it is to be formed by matrix, RF transmitter, infrared receiver, circuit four part-structure;Its sensing principle is: when having drop pass through or have liquid communication in transparent, vertical pipeline, the infrared ray that RF transmitter is launched is stopped by the liquid of the drop in pipeline or continuous flow, infrared receiver does not just receive the infrared ray that RF transmitter is launched, and therefore circuit just creates the signal of telecommunication of drop or liquid communication;When not having drop or liquid communication in transparent, vertical pipeline, the infrared ray that RF transmitter is launched can be received by infrared receiver, and circuit just can be produced without the signal of telecommunication and the relevant action of drop or liquid communication.
As previously mentioned: transparent, vertical pipeline is the premise being suitable for working fluid measuring and testing device, and transparent duct wall is suitable for the infrared penetration that RF transmitter is launched;Vertical pipeline ensure that working fluid measuring and testing device gauge check exactly is monitored.
As previously mentioned " matrix ", it is wrapped on transparent, vertical pipeline, and the internal diameter of matrix is consistent with the external diameter of the pipeline surrounded by it;Matrix is again the carrier of RF transmitter, infrared receiver, circuit part.
" matrix " is opened on matrix and is shaped with through through hole as previously mentioned, and the through hole of matrix side opens system for placing RF transmitter, and the through hole of matrix opposite side opens system for placing infrared receiver;Matrix is provided with relevant circuit.
RF transmitter as previously mentioned, can send the infrared ray being not less than 940 nano wave lengths after powered up, and it can be LED light emitting diode, it is also possible to be LD semiconductor laser.
Infrared receiver as previously mentioned, it is made up of wave filter and light sensitive diode, the wave filter of its prime can filter out visible ray, light sensitive diode is able to receive that the infrared ray that RF transmitter is launched, when having infrared ray, the circuit being connected with light sensitive diode is in " leading to " state, and during without infrared ray, the circuit being connected with light sensitive diode is in " breaking " state.
Circuit part as previously mentioned, it is attached on matrix the side of infrared receiver, and circuit part becomes the corresponding signal of telecommunication " leading to " " breaking " State Transferring of infrared receiver.
The beneficial effects of the utility model are: a kind of working fluid measuring and testing device, it needs the liquid of flowing in transparent, vertical pipeline is counted, measures, detects, monitored suitable in many occasions such as production, life, scientific experiments, can obtain good economic benefit and social benefit after popularization and application.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model.
In accompanying drawing 1: 1 transparent vertical pipeline 2 matrix 3 RF transmitter 4 is with infrared receiver 5 circuit part of wave filter.
(5) detailed description of the invention
As shown in Figure 1, this utility model one working fluid measuring and testing device, the internal diameter of its matrix 2 matches with the external diameter of transparent, vertical pipeline, the through hole of matrix 2 side is provided with RF transmitter 3, the through hole of matrix 2 opposite side is provided with the infrared receiver 4 of wave filter, being provided with circuit part 5 on matrix 2, after circuit part 5 is energized, this working fluid measuring and testing device just can normal operation.

Claims (1)

1. a working fluid measuring and testing device, it is characterized in that: matrix opens, on (2), the through hole being shaped with decussation, the side of matrix (2) horizontal through hole is provided with RF transmitter (3), the opposite side of horizontal through hole is provided with the infrared receiver (4) with wave filter, and matrix (2) is provided with circuit part (5).
