Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As the structural representation that Fig. 1 ~ Fig. 4 is baffle board device.
A kind of reflective level meter caliberating device, comprise baffle board device and and the guide tracked thing distance of positions from checkout console, it is characterized in that: described baffle board device (as shown in figures 1-4); Be made up of mounting base 1, travel(l)ing rest 5 and reflecting plate 4; Level tune supporting 2 is equipped with below described mounting base 1, above described mounting base 1, two fixed supports 9 are connected and fixed by screw thread is vertical with described mounting base 1, and be symmetrical arranged each other: fixed support 9 described with two is telescopic respectively two described travel(l)ing rest 5 lower ends is connected, and is fixed by latch 8; Described reflecting plate 4 left and right sides is equipped with cross bar 6 in the middle part of limit respectively, and described cross bar 6 is placed in the groove of two symmetrically arranged travel(l)ing rest 5 upper ends respectively; Described reflecting plate 4 surface indicates the marked net ruling 10(of level and vertical direction as shown in Figure 5), reflecting plate 4 lower side hangs with weight 3.
The described guide tracked thing distance of positions is from checkout console, comprise operation stand, be placed in the dull and stereotyped and standard stadimeter erecting frame of transmission on described operator's console, two standard stadimeter Parallel Symmetrics are placed in the two ends, left and right of described standard stadimeter erecting frame, and the distance between two standard stadimeters is greater than the width of described transmission flat board.
The quantity of described adjustable horizontal supporting is 4.
The quantity of described weight is 2.
Use the guide tracked scaling method of said reflection plate unit simulation, it is characterized in that: be from the close-by examples to those far off arranged in order multiple stage baffle board device (as shown in Figure 5), from the calibration point of first piece of reflecting plate 4, launched marked net ruling 10 that two bundles and the contour visual laser spots of same level be radiated at reflecting plate 4 surface formed by standard stadimeter described in operator's console and project, according to the installation site of projected position adjustment mounting base 1 and by regulating the height of Level tune supporting to regulate the levelness of mounting base in horizontal and vertical both direction, line number and the columns of the projection correspondence finally making laser spots be formed on each reflecting plate 4 are all in identical position, can keep projection that each laser spots is formed on each reflecting plate point-blank, thus simulate each calibration point situation on the same track.
Baffle board device of the present invention in use, can fixed support 9 described with two be telescopic is respectively connected by two described travel(l)ing rests 5, and is fixed by latch 8; The cross bar 6 be furnished with in described reflecting plate about 4 side, and the groove being placed in two symmetrically arranged travel(l)ing rest 5 tops respectively; Described reflecting plate 4 surface indicates the marked net ruling 10 of level and vertical direction.Utilize two weights 3 hung on below reflecting plate 4, using cross bar 6 as fulcrum, under the effect of the gravity of weight 3 own, automatically reflecting plate 4 and surface level is made to keep vertical, the projection of visual laser spots on reflecting plate 4 mesh lines that two bundles utilizing operator's console to launch are contour with same level, by regulating the height of 4 horizontal supportings 2, subpoint is in a straight line, thus ensures the levelness of mounting base 1 in horizontal and vertical both direction.
Utilize many cover mounting bases 1 and travel(l)ing rest 5, according to spacing distance required when detecting fixed installation, the combination of any range, different calibrating point can be realized, the calibration point paid close attention to hangs reflecting plate.Do not needing to use in the occasion of reflecting plate, remove reflecting plate 4 and weight 3, extracting latch 8 can take off travel(l)ing rest 5, does not affect the follow-up use (see figure 5) of this reflection unit.The mounting means of this adjustable distance, makes the present invention both go for the calibrating of the short range level meters such as ultrasound wave, may be used for equally again the calibrating of the isometric range level meter of radar.
Operator's console supporting with it can be installed the transmitter-receiver device of ultrasound wave or radar, ultrasound wave (or radar) signal launched is through the reflection of reflection unit, thus received by the receiving trap of its correspondence, the distance between operator's console and reflection unit can be calculated according to reflection interval, calculate through the conversion of follow-up numerical value and can realize the function that thing position measured by level meter.
Above to the description of embodiment, be intended to further illustrate the technical scheme that the present invention relates to, enable those of ordinary skill in the art's application implementation the present invention.Be to be understood that every based on the present invention's enlightenment, any apparent conversion or equivalent alternative, also should be considered to fall into protection scope of the present invention.
