Description
Technical field
The present invention relates to a kind of article position measuring device, particularly a kind of method for designing of magnetic-suspension optoelectronic scanning level gauging sensing head.
Background technology
Chinese patent 200410026069.8 discloses (a kind of liquid position measuring method), it by be fixed with inner core along the container height direction, the magnetic float is socketed on the inner core, when liquid level moves, the magnetic float moves relative to inner core, along the container height design height mark information is arranged in the inner core, the reading device that height mark information is arranged in the inner core, when float changes up and down with liquid level, float drives reading device and moves up and down, reading device reads the container height label information constantly, and is that electric signal is outwards exported by signal output interface with the height mark information translation.
Summary of the invention
The purpose of this invention is to provide the method for designing that a kind of technology is simple, good reliability is fit to a kind of magnetic-suspension optoelectronic scanning level gauging sensing head of 5 meters height level gaugings
The object of the present invention is achieved like this, a kind of method for designing of magnetic-suspension optoelectronic scanning level gauging sensing head, it is characterized in that: read head comprises cylindrical shell, loam cake, lower cover, lower cover is connected with the cylindrical shell lower end, loam cake and cylindrical shell upper end is connected, and cylindrical shell, loam cake and lower cover one side have semicircle orifice, the semicircle orifice of cylindrical shell, loam cake and lower cover about on the straight line, observe by loam cake or lower cover, semicircle orifice penetrates whole read head; Coded level ruler is a semicircular body, and the plane face of semicircular body has passed through and along length coding arranged, and coded level ruler section shape along its length is identical, and read head is socketed on the coded level ruler.
Described read head lower end and semicircle orifice relative position have the little cylindrical cavity of self-contained battery, after battery is put into self-contained battery roundlet chamber, are connected with lower cover with screw thread by the tegillum of being with screw thread.
Described read head lower end is socketed with magnet ring around external diameter, and the magnet ring external diameter is identical with the external diameter size of cylindrical shell, loam cake, lower cover.
The section shape of described coded level ruler is less than the semicircle orifice that penetrates whole read head.
There is light hole in the central authorities that cover on described, and light hole can directly cooperate fixedly luminotron, or cooperate fixedly collimation lens, and luminotron upwards sends liquid level information by collimation lens.
Advantage of the present invention is: because sensing head comprises cylindrical shell, loam cake and lower cover, cylindrical shell, loam cake and lower cover one side have semicircle orifice, the coded level ruler cross section is a semicircular body, coded level ruler length is according to the Design of length of measuring liquid level, when sensing head moves up and down with liquid level magnetic float magneticaction, is that coded level ruler with semicircular body is a guide pole, the coded level ruler that is to say semicircular body is promptly as coded level ruler, semicircular body is again as guide pole location, good reliability not only, and also design technology is simple.
Description of drawings
The invention will be further described below in conjunction with the embodiment accompanying drawing:
Fig. 1 is an embodiment of the invention first half structural representation;
Fig. 2 is an embodiment of the invention Lower Half structural representation.
Among the figure, 1, cylindrical shell; 2, loam cake; 3, lower cover; 4, screw thread; 5, screw; 6, semicircle orifice; 7, coded level ruler; 8, the little cylindrical cavity of self-contained battery; 9, the tegillum of band screw thread; 10, read head circuit erecting frame; 11, magnet ring.
Embodiment
Fig. 1 is an embodiment first half structural representation, and Fig. 2 is an embodiment Lower Half structural representation.Provide full implementation example structure of the present invention by the structure of Fig. 1 and the structure combination of Fig. 2.
Embodiments of the invention as depicted in figs. 1 and 2, read head comprises cylindrical shell 1, loam cake 2, lower cover 3, lower cover 3 is connected by screw thread 4 with cylindrical shell 1, loam cake 2 adopts screw 5 to be connected with cylindrical shell 1, cylindrical shell 1, loam cake 2 and lower cover 3 one sides have semicircle orifice 6, the semicircle orifice 6 of cylindrical shell 1, loam cake 2 and lower cover 3 is observed by loam cake 2 or lower cover 3 on straight line up and down, and semicircle orifice 6 penetrates whole read head.
Read head lower end and semicircle orifice 6 relative positions have self-contained battery roundlet chamber 8, after battery is put into self-contained battery roundlet chamber 8, are connected with lower cover 3 with screw thread by the tegillum 9 of being with screw thread.
The read head lower end is socketed with magnet ring 11 around external diameter, and magnet ring 11 external diameters are identical with the external diameter size of cylindrical shell 1, loam cake 2, lower cover 3.
Coded level ruler 7 is a semicircular body, and the plane face of semicircular body has passed through and along length coding arranged, and coded level ruler 7 section shape along its length is identical.
