Description
Technical field
The present invention relates to a kind of article position measuring device, particularly a kind of magnetic suspension photoelectric scanning liquid level measuring sensing head.
Background technology
Chinese patent 200410026069.8 discloses (a kind of liquid position measuring method), it by being fixed with inner core along container height direction, magnetic float is socketed on inner core, when liquid level moves, magnetic float moves relative to inner core, it is designed with number of altitude information along container height in inner core, the reading device of number of altitude information is had in inner core, when float changes up and down with liquid level, float drives reading device to move up and down, reading device reads container height label information constantly, and number of altitude information is converted to the signal of telecommunication is outwards exported by signal output interface.
Summary of the invention
It is an object of the invention to provide a kind of magnetic suspension photoelectric scanning liquid level measuring sensing head that a kind of technique is simple, good reliability is suitable for 5 meters of height level measurements。
The object of the present invention is achieved like this, a kind of magnetic suspension photoelectric scanning liquid level measuring sensing head, it is characterized in that: read head includes cylinder, upper cover, lower cover, lower cover is connected with cylinder lower end, upper cover is connected with cylinder upper end, and there is semicircle orifice cylinder, upper cover and lower cover side, and the semicircle orifice of cylinder, upper cover and lower cover is on upper and lower straight line, being observed by upper cover or lower cover, semicircle orifice penetrates whole read head；Coded level ruler is semicircular body, and the plane face of semicircular body has passed through has coding along length, and coded level ruler section shape along its length is identical, and read head is socketed on coded level ruler.
Described read head lower end has the little cylindrical cavity of self-contained battery with semicircle orifice relative to position, after the little cylindrical cavity of self-contained battery put into by battery, is connected with lower cover with screw thread by the tegillum of band screw thread.
Described read head lower end is socketed with magnet ring around external diameter, magnet ring external diameter and cylinder, upper cover, lower cover external diameter size identical.
The section shape of described coded level ruler is less than the semicircle orifice penetrating whole read head.
There are loophole in the central authorities covered on described, and loophole can directly coordinate fixing luminous tube, or coordinates fixing collimating lens, and luminous tube sends up liquid level information by collimating lens.
The invention have the advantage that owing to sensing head includes cylinder, upper cover and lower cover, there is semicircle orifice cylinder, upper cover and lower cover side, coded level ruler cross section is semicircular body, coded level ruler length, according to measuring the Design of length of liquid level, when sensing head moves up and down with liquid level magnetic float magneticaction, is with the coded level ruler of semicircular body as guide post, that is the coded level ruler of semicircular body is i.e. as coded level ruler, semicircular body positions as guide post again, not only good reliability, and design technology is simple.
Accompanying drawing explanation
Below in conjunction with embodiment accompanying drawing, the invention will be further described:
Fig. 1 is embodiment of the present invention first half structural representation；
Fig. 2 is embodiment of the present invention lower half structural representation.
In figure, 1, cylinder；2, upper cover；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 installing rack；11, magnet ring.
Detailed description of the invention
Fig. 1 is embodiment first half structural representation, and Fig. 2 is embodiment lower half structural representation.The complete embodiment structure providing the present invention is combined by the structure of Fig. 1 and the structure of Fig. 2.
Embodiment 1
Embodiments of the invention are as depicted in figs. 1 and 2, read head includes cylinder 1, upper cover 2, lower cover 3, lower cover 3 is connected by screw thread 4 with cylinder 1, upper cover 2 uses screw 5 to be connected with cylinder 1, there is semicircle orifice 6 cylinder 1, upper cover 2 and lower cover 3 side, the semicircle orifice 6 of cylinder 1, upper cover 2 and lower cover 3, on upper and lower straight line, is observed by upper cover 2 or lower cover 3, and semicircle orifice 6 penetrates whole read head.
There is the little cylindrical cavity of self-contained battery 8 position relative with semicircle orifice 6, read head lower end, after the little cylindrical cavity of self-contained battery 8 put into by battery, is connected with lower cover 3 with screw thread by the tegillum 9 of band screw thread.
Read head lower end is socketed with magnet ring 11 around external diameter, magnet ring 11 external diameter and cylinder 1, upper cover 2, lower cover 3 external diameter size identical.
Coded level ruler 7 is semicircular body, and the plane face of semicircular body has passed through has coding along length, and coded level ruler 7 section shape along its length is identical.
The section shape of coded level ruler 7 is less than the semicircle orifice 6 penetrating whole read head.
There are loophole in central authorities on upper cover 2, and loophole can directly coordinate fixing luminous tube, or coordinates fixing collimating lens, and luminous tube sends up liquid level information by collimating lens.
During work, coded level ruler 7 upper and lower side is fixed in the sealing pipe that the upper and lower side of liquid level container is fixing, seals pipe outer socket magnetic float, and read head is enclosed within outside coded level ruler 7, seals bore more than read head external diameter.There is transmitter the upper end of liquid level container, receives the liquid level information of read head collection and is sent to control room.When read head moves up and down, semicircle coded level ruler plays location and guide effect.When sensing head moves up and down with liquid level magnetic float magneticaction, it is with the coded level ruler of semicircular body as guide post, say, that the coded level ruler of semicircular body is i.e. as coded level ruler, and semicircular body positions as guide post again, not only good reliability, and design technology is simple.
