Detailed description of the invention
As shown in Figure 1, the present invention is stuck in the outside of Murphy's burette 1, comprise left clasp 2, right clasp 3, central controller 9, power supply, audible-visual annunciator 10, power supply is connected with left clasp 2, right clasp 3 and provides power supply for left clasp 2, right clasp 3, left clasp 2, right clasp 3 and central controller 9 control connection.Central controller 9 is connected with audible-visual annunciator simultaneously.Between left clasp 2, right clasp 3, observation window 11 is all left in both sides, makes people still can observe the change of liquid level.
As shown in Figure 2, left clasp 2 and right clasp 3 symmetrical shape, be provided with bayonet unit 6 at the two top and bottom, left clasp 2 and right clasp 3 snapped together.Bayonet unit 6 can be that left clasp 2 and right clasp 3 correspondence be equipped with can the buckle of buckle, also can be the side of left clasp 2 and right clasp 3 by rotating shaft hinged (being rotationally connected), opposite side is connected by buckle, can open fast.
As shown in Figure 3, left clasp 2 is the arc surface of 120 degree (angle can set according to actual needs), because the shape of needs and dropper 1 is coincide, dropper 1 is up big and down small, so the mid portion of left clasp 2 slopes inwardly, the medial surface of left clasp 2 is evenly densely covered with several miniature light emission pipe 4 and light receiver pipes 5, light emission pipe 4 and light receiver pipe 5 belong to prior art.Light emission pipe 4 for emission of light, the light that light receiver pipe 5 launches for receiving light emission pipe 4.Although the inner surface of left clasp 2 is arc, but the radiation direction that all light emission pipes 4 are launched is parallel, the receive direction of light receiver pipe 5 is also parallel simultaneously, so light emission pipe 4 and light receiver pipe 5 all be arranged in parallel, can not be along the circumferential direction arrange to center.
In a lateral direction, the center of left clasp 2 has demarcation line 31(to be often referred to centrage), light emission pipe 4 and light receiver pipe 5 lay respectively at the left and right sides of demarcation line 31.
Right clasp 3 is identical with left clasp 2, and the left and right of demarcation line 31 is also light emission pipe 4 and light receiver pipe 5 respectively.Like this when the two is mounted opposite, the light that the light emission pipe 4 that light receiver pipe 5 can receive opposite is just launched.Central controller 9 adopts PLC system to programme, and controls the transmitting of light emission pipe 4 and the Signal reception of light receiver pipe 5, and compares to it, judges.
Principle of the present invention:
According to physics principle, light is when oblique incidence, and the object density of process is different, and will reflect, the light in the object that density is large and normal angle are less than the angle of incident ray and normal.
As shown in Figure 4, dropper 1 is circular, and there is liquid its underpart, and top does not have liquid.If light A is through there being liquid part, then light along dropper 1 vertical cross-section by time, be oblique incidence, can through the tube wall 7 of dropper 1, then through liquid, then through tube wall 7, occurs three times and reflect.
As shown in Figure 5,6, if light B is through no liquid part, then only at tube wall 7 place, twice refraction occurs, and because tube wall density is the same, the angle of light is the same, only slightly towards certain distance that moves right.Will find through contrast, light A, light B, through after the tube wall 7 on opposite, have a range difference d at horizontal direction therebetween.
The present invention utilizes this difference to judge just, by certain string vertical or there is the multiple row light emission pipe 4 of appropriate intervals to open, certain row light receiver pipe 5 can only have the some light receiving tube 5 on the downside of liquid level 8 to receive signal, and the light receiver pipe 5 on the upside of liquid level 8 can not receive light signal, even if the dropper wall on the upside of liquid level 8 is attached with some liquid drop, the optical signal that part on the upside of this row light receiver pipe 5 receives is still mixed and disorderly and interrupted, can judge height and the level change of liquid level 8 equally.Different by the receiving position of light after the refraction of liquid level about 8 in comparison dropper 1, and then judge the change of liquid level 8, if the refracted ray position of the reception on the upside of liquid level 8 is different with the refracted ray position on the downside of liquid level 8, illustrate in dropper 1 have liquid, if the liquid level in dropper 1 starts to decline, then central controller 9 drives audible-visual annunciator 10 to send acousto-optic early warning, if decrease speed is very fast, then illustrate in dropper 1 and will drip off at once, need to close at once, then central controller drives audible-visual annunciator 10 to send another kind of acousto-optic early warning, remind family members and nurse's Immediate management.
