Embodiment
Below in conjunction with drawings and Examples, further describe content of the present invention.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of fuel tank liquid level height measuring device of the present invention comprises scale bar 1, tightrope 4 and float 5.Scale bar 1 vertically extends, and has up and down two ends, and zero graduation is located at the upper end, and the scale value on the shaft increases from top to bottom gradually.Be provided with the first conductor rope ring 11 in the bottom of scale bar 1.Tightrope 4 also has up and down two ends, is provided with fixation mark point 41 between two ends, is used for the scale value on the indicating graduation bar 1 when measuring liquid level.The bottom of tightrope 4 is connected with float 5, and float 5 can swim in the liquid level place under buoyancy.The upper end of tightrope 4 passes from the first conductor rope ring 11 along scale bar 1 is bottom-up.Also the 4th conductor rope ring 12 can be set in the upper end of scale bar 1, the upper end of tightrope 4 passes from the first conductor rope ring 11 and the 4th conductor rope ring 12 successively.
In a preferred embodiment, the present invention also comprises the base 3 as supporting base, and scale bar 1 is connected on the base 3.When measurement mechanism of the present invention was put into fuel tank, base 3 can be fitted with fuel tank bottom surface inwall.As shown in Figure 4, can be provided with through hole 34 on the base 3, to reduce base 3 be put into liquid level suffered resistance of lower time.Base 3 can arrange interface arrangement 31.This interface arrangement 31 can have internal thread, and the bottom of scale bar 1 is provided with the external thread suitable with this internal thread, is threaded connection between scale bar 1 and the base 3.The second conductor rope ring 32 can be provided with at interface arrangement 31 places, the 3rd conductor rope ring 33 can also be provided with in the edge of base 3.The upper end of tightrope 4 is passed from the 3rd conductor rope ring 33 and the second conductor rope ring 32 successively, passes through the first conductor rope ring 11 and the 4th conductor rope ring 12 again.Can be provided with pulley at the second conductor rope ring 32 and the 3rd conductor rope ring 33, tightrope 4 holds the local wheel face through pulley.In order to improve the accuracy of measurement, it is smaller that conductor rope ring 32,33,11 and 12 should arrange as far as possible, only need make tightrope 4 freely pass through to get final product.
The present invention can also comprise connecting link 2, and scale bar 1 is connected on the base 3 by connecting link 2.Base 3 is connected with the scale bar and can be connected with connecting link 2 by screw thread respectively, by the screw thread precession or screw out to adjust scale bar 1 and base 3 between relative position, thereby can be used for calibrating the initial scale of fuel tank liquid level height measuring device of the present invention.When the height of fuel tank is low, can directly be connected with base 3 by scale bar 1 and gets final product.When the height of fuel tank is higher, increases connecting link 2 and can avoid using separately the length of scale bar 1 bigger than normal.
Wherein, base 3, scale bar 1 and connecting link 2 can be made by metal material.Tightrope 4 can be made by fuel-proof non-elastic material.
Below, with reference to the synoptic diagram shown in Fig. 2, measuring method of the present invention is described.As shown in Figure 2, device of the present invention is slowly put into fuel tank, when initial position, the distance of (namely fuel tank bottom) is h0 to float 5 apart from base 3 bottom surfaces.By rotating scale bar 1 and connecting link 2, regulate rule 1 apart from the distance of base 3, so that straight up behind the stretching tightrope, the h0 scale value place on the 41 corresponding scale bars 1 is put in fixation mark.Along with liquid level in the fuel tank rises, float 5 moves up, thereby the fixation mark point 41 that drives on the tightrope 4 moves down.Move height and fixation mark point 41 on the float 5 and move down highly unanimously, therefore, the reading that 41 correspondences are put in fixation mark is exactly the height of the interior liquid level of fuel tank.
