Embodiment
The present invention proposes a kind of single air cleft bandwidth detection sensor, and it makes simple, and production cost is low, can use in various rugged environments, realizes having very high practical value easily.
First embodiment of single air cleft bandwidth detection sensor involved in the present invention as shown in Figure 1.Two parts mainly are set on the support 5 to be formed, leave air cleft between these two parts and detect space 9, a part is that first air cleft forms the unit, comprise that generating plate 4 by first inlet plate 6 and first air cleft is bolted to connection first air chamber 11 that constitutes, and first inlet plate 6 and first air cleft generate between the plate 4 to being tightly connected, as Fig. 3, Fig. 4 and shown in Figure 5, wherein, Fig. 3 has shown that first air cleft forms the inner structure of unit and air cleft detecting unit, one side of first inlet plate 6 is provided with inlet suction port 7 is installed on first air intake opening, 10, the first air intake openings 10.On first air cleft generation plate 4 first slit, 12, the first inlet suction ports 7 being set links to each other with the source of the gas 8 that has regulator.
Another part of sensor is to form the air cleft detecting unit that the unit is fixed together by the bolt and first air cleft, this air cleft detecting unit comprises the check-out console 3 of fixedlying connected with first air cleft generation plate 4, test chamber 13 is set on the check-out console 3, some gas detecting tubes 2 are set in the test chamber 13, and the position of gas detecting tube 2 is corresponding with the position that first air cleft generates first slit 12 on the plate 4.Gas detecting tube 2 links to each other with the signals collecting conversion and the computer information processing system 1 that have the pneumoelectric sensor.The quantity of the gas detecting tube 2 that is provided with in the test chamber 13 is many more, and the precision of detection is just high more.
During work, the air cleft of the band steel slowly being sent into this sensor detects in the space 9, as shown in Figure 2, open source of the gas 8, gases at high pressure import in first air chamber 11 by first inlet suction port 7, form voltage stabilizing gas, and pass through the effect cambium layer gas body in first slit 12, be air cleft, width is 0.03mm～0.05mm.Do not detect in the space 9 through out-of-date from air cleft when there being the band steel, laminar flow gas will enter gas detecting tube 2, and changes and computer information processing system 1 records signal by the signals collecting that has the pneumoelectric sensor.Detect in the space 9 through out-of-date from air cleft as the band steel, because gas can not penetrate the band steel, air cleft by first generates the laminar flow gas of plate 4 generations and is with steel to shelter from, make corresponding being covered in the gas detecting tube 2 partly not receive gas signal by the band steel, do not covered in the gas detecting tube partly 2 and can receive gas signal, will detect the parameters such as width of band steel like this by the computer information processing system 1 that has pneumatic-electric signal collection conversion that links to each other with gas detecting tube 2 by the band steel.
The second embodiment of the present invention is similar to first example structure, and different is second air cleft that is connected with the source of the gas 8 that has regulator also to be set on the support 5 form the unit, as shown in Figure 6.It is the same substantially with first air cleft formation cellular construction that this second air cleft forms cellular construction, as Fig. 8, Fig. 9 and shown in Figure 10, wherein, Fig. 8 has shown that second air cleft forms the inner structure of unit, be inside be provided with second air chamber 11 ', second inlet suction port 7 of outer setting and second air chamber 11 ' be connected ' and produce second slit 12 of second air cleft '.Need to prove that this second air cleft forms second slit 12 in unit ' parallel with first slit 12 of first air cleft formation unit, second air cleft of second slit 12 ' generation passes that air cleft detects space 9 and its direction is perpendicular with the direction of first air cleft of described first slit, 12 generations, and in use, the band steel does not pass through from the air cleft detection space 9 that first air cleft forms between unit and the air cleft detecting unit, but in the space between first air cleft formation unit and second air cleft formation unit, pass through, accept detection.
First air cleft forms the working position of unit, second air cleft formation unit and air cleft detecting unit and puts as shown in Figure 6.First air cleft formation unit and air cleft detecting unit promptly form the laminar flow gas of horizontal direction in last horizontal positioned.Second air cleft formation unit is vertically being placed down, and promptly the laminar flow gas direction of Xing Chenging blows to the air cleft detection space 9 that first air cleft generates plate 4 straight up, and two-layer gas body is orthogonal.
During work, as shown in Figure 7, open source of the gas 8, gas will form first air chamber 11 of unit and second air chamber 11 ' interior generation voltage stabilizing gas that second air cleft forms the unit at first air cleft, and by first slit 12 and second slit 12 ' generation first air cleft and second air cleft, first air cleft and second air cleft detect space 9 at air cleft and interfere, and result of interference makes two air clefts flow to atmosphere from different directions, and two air cleft width are 0.03mm～0.05mm.Regulate the gaseous tension of first air cleft and second air cleft and can control the flow direction that two air clefts are interfered back gas, regulate regulator in the present embodiment and make the air cleft of winning form the gaseous tension of unit greater than the gaseous tension in second air cleft formation unit.The band steel is passed through from the space that first air cleft forms between unit and second air cleft formation unit.When not being with steel to pass through, by regulating the gaseous tension of first air cleft and second air cleft, make and do not receive gas signal in the gas detecting tube 2, when the band steel passes through, because forming unit generation laminar flow gas, second air cleft is with steel to block, at this moment, the gas signal that only has first air cleft to form the unit generation can be received by gas detecting tube 2, and in computer system, show, just can't do not received by gas detecting tube 2 by the gas signal of first air cleft of being with steel to block, also just in computer system, can't show, can realize the measurement of bandwidth thus.
This sensor construction is simple, easy to use, by adopting the mode of gas micrometer, the bandwidth of band steel and the quality of plate face are measured accurately, made full use of the character of air cleft, come the wide and plate face quality of check-out console by the variation that detects air cleft gas, production cost is low, can in various rugged environments, use, realize having very high practical value easily.
Obviously; the foregoing description only is for giving an example of being done clearly is described; and be not limitation of the invention; for the person of ordinary skill of the art; can also make other multi-form variations on the basis of the above description; the form of the composition of air chamber for example; air cleft detecting unit and first air cleft formation unit can not be fixed together the gas signal that only need make gas detecting tube can receive air cleft and get final product; or the like; here also need not carry out exhaustive for all embodiments; and the conspicuous variation that is proposed thus still is within protection scope of the present invention.
