Accompanying drawing explanation
The structural representation of the banded chi driving device for oil tank internal liquid level measuring system that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the schematic diagram of banded chi.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model content of the present utility model is further described.
As shown in Figure 1, the banded chi driving device for oil tank internal liquid level measuring system that the present embodiment provides comprises the chi dish 2 be fixedly installed on adapter plate 1, code wheel 3, first roller 4 and the second roller 5.
As shown in Figure 1, the center-point of chi dish 2 is A point; The center-point of code wheel 3 is B point; The center-point of the first roller 4 is D point; The center-point of the second roller 5 is E point; Straight line AC is horizon.The center position of chi dish 2 is provided with the winding axle 8 for being wound in plate-like for banded chi 9, and chi dish 2 can curl and rotates around axle 8.Chi dish 2 is wound in the banded chi 9 of plate-like for holding.Code wheel 3 is disposed adjacent with chi dish 2, and code wheel 3 can rotate around its center-point B, and code wheel 3 is provided with the pin (not shown) that can coordinate with the knock hole 10 on banded chi 9.First roller 4 and the second roller 5 are all arranged at the side away from chi dish 2 of code wheel 3, and the first roller 4 can rotate around its center-point D, and the second roller 5 can rotate around its center-point E.The the first gap (not shown) can passed for banded chi 9 is provided with between first roller 4 and code wheel 3; The the second gap (not shown) can passed for banded chi 9 is provided with between second roller 5 and code wheel 3.During use, banded chi 9 is successively through the first gap and the second gap.First roller 4 and the second roller 5 are close to code wheel 3 for making banded chi 9.
In a kind of preferred implementation of the present embodiment, the line DB of the center-point D of the first roller 4 and the center-point B of code wheel 3 vertically.The line EB of the center-point E of the second roller 5 and the center-point B of code wheel 3 in the horizontal direction.Angle between the line of centres AB of code wheel 3 and chi dish 2 and horizon AC is 30-35 °.
In the one of the present embodiment more preferably in embodiment, the angle between the line of centres AB of code wheel 3 and chi dish 2 and horizon AC is 33.2 °.
Adapter plate 1 is also fixedly installed alignment light electric switch 6, and alignment light electric switch 6 is positioned at the below of code wheel 3 and the second roller 5.Alignment light electric switch 6 is in U-shaped, and one of them arm launches infrared ray, and be called launcher arm, another arm receiving infrared-ray, is called receptor arm.Banded chi 9 passes between the two-arm of alignment light electric switch 6.
As shown in Figure 2, banded chi 9 is provided with a line arrangement and the multiple knock hole 10 of well-distributed, and banded chi 9 is provided with scale.The end of banded chi 9 is fixedly connected with probe 7.
When probe 7 is sunk to oil tank internal detection liquid level by needs, the banded chi 9 being wound in plate-like stretches under the Action of Gravity Field of probe 7, and moves downward along vertical direction through behind the second gap.When code wheel 3 walked around by banded chi 9, the knock hole 10 on banded chi 9 and the bayonet fittings on code wheel 3, make the motion of banded chi 9 drive code wheel 3 to rotate, thus realize the coding count of code wheel 3.In brief, when probe 7 along vertical direction sink to oil tank inner time, due to pop one's head in 7 Action of Gravity Field, probe 7 drives banded chi 9, and banded chi 9 drives code wheel 3.
When banded chi 9 does sunken caves relative to alignment light electric switch 6, banded chi 9 is continuously across alignment light electric switch 6 place, when the knock hole 10 on banded chi 9 passes the two-arm of alignment light electric switch 6, the infrared ray that alignment light electric switch 6 launcher arm is launched can through the knock hole 10 of banded chi 9, and the receptor arm of alignment light electric switch 6 can receive the infrared ray from launcher arm; Otherwise, when on banded chi 9 except knock hole 10 partially pass through the two-arm of alignment light electric switch 6 time, the receptor arm of alignment light electric switch 6 cannot receive the infrared ray from launcher arm.The distance of sunken caves accurately obtaining banded chi 9 measured by alignment light electric switch 6, and realizes the continuous periodic calibration to banded chi 9 according to result of detection.
When probe 7 takes out from oil tank inside by needs, by the winding axle 8 of such as hand mode rotary ruler dish 2, banded chi 9 is wrapped in and is wound around on axle 8, and the banded chi 9 be wrapped on winding axle 8 is in plate-like.When banded chi 9 does upward movement relative to alignment light electric switch 6, banded chi 9 is continuously across alignment light electric switch 6 place, with in like manner above-mentioned, the upward movement of alignment light electric switch 6 to banded chi 9 detects, measure the upward movement distance accurately obtaining banded chi 9, and realize the continuous periodic calibration to banded chi 9 according to result of detection.
Should be appreciated that above is illustrative and not restrictive by preferred embodiment to the detailed description that the technical solution of the utility model is carried out.Those of ordinary skill in the art can modify to the technical scheme described in each embodiment on the basis of reading the utility model specification sheets, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
