The specific embodiment
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 for left clasp 2, right clasp 3 provide power supply, left clasp 2, right clasp 3 and central controller 9 control connections.Central controller 9 is connected with audible-visual annunciator simultaneously.Observation window 11 is all left in both sides between left side clasp 2, the right clasp 3, makes people still can observe the variation of liquid level.
As shown in Figure 2, left clasp 2 and right clasp 3 shape symmetries are provided with bayonet unit 6 in the two top and bottom, and left clasp 2 and right clasp 3 are snapped together.But bayonet unit 6 can be the buckle that left clasp 2 and right clasp 3 correspondences are equipped with buckle, and a side that also can be left clasp 2 and right clasp 3 is by rotating shaft hinged (being rotationally connected), and opposite side connects by buckle, can open fast.
As shown in Figure 3, left side clasp 2 is the arc surface of 120 degree (angle can be 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, evenly be densely covered with several miniature light emission pipe 4 and light receiving tubes 5 on the medial surface of left side clasp 2, light emission pipe 4 and light receiving tube 5 belong to prior art.Light emission pipe 4 is used to launch light, and light receiving tube 5 is used to receive the light that light emission pipe 4 launches.Though the inner surface of left clasp 2 is an arc, but the radiation direction of all light emission pipe 4 emissions is parallel, the receive direction of light receiving tube 5 also is parallel simultaneously, so light emission pipe 4 and light receiving tube 5 all be arranged in parallel, can not be along the circumferential direction to be provided with to the 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 receiving tube 5 lay respectively at the left and right sides of demarcation line 31.
Principle of the present invention:
According to physics principle, light is when oblique incidence, and the object density difference of process will reflect, and light in the big object of density 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 a liquid part, then light along dropper 1 vertical cross-section by the time, be oblique incidence, can pass through liquid again through the tube wall 7 of dropper 1, pass through tube wall 7 again, takes place three times and reflects.
Shown in Fig. 5,6, if light B through the no liquid part, then only at tube wall 7 places twice refraction takes place, and because tube wall density is the same, the angle of light is the same, and certain distance slightly only moves right.Will find through contrast, after light A, light B pass the tube wall 7 on opposite, have a range difference d at horizontal direction between the two.
The present invention utilizes this difference to judge just, with vertical certain string or there is the multiple row light emission pipe 4 of appropriate intervals to open, certain row light receiving tube 5 can have only the part light receiving tube 5 of liquid level 8 downsides to receive signal, and the light receiving tube 5 of liquid level 8 upsides can not receive light signal, even be attached with some liquid water droplets on the dropper wall of liquid level 8 upsides, the optical signal that the part of these row light receiving tube 5 upsides receives is still mixed and disorderly and alternate, can judge the height and the level change of liquid level 8 equally.Receiving position difference by light after the refraction of liquid level about in the of 8 in the comparison dropper 1, and then the variation of judgement liquid level 8, if the refracted ray position of the reception of liquid level 8 upsides is different with the refracted ray position of liquid level 8 downsides, illustrate in the dropper 1 liquid is arranged, if the liquid level in the dropper 1 begins to descend, then central controller 9 drives audible-visual annunciator 10 and sends the acousto-optic early warning, if decrease speed is very fast, then illustrate in the dropper 1 and will drip off at once, need close at once, then central controller drives audible-visual annunciator 10 and sends another kind of acousto-optic early warning, reminds family members and nurse to handle at once.
