Abstract

The utility model belongs to height testing equipment for oil tank liquid level, particularly suitable for the horizontal oil tank underground or half-underground. The utility model is characterized in that a float floating on the liquid level is connected with a shaft by a set of four-bar linkage which is composed of parallelograms. When the float lifts following the liquid level, the shaft rotates in a bearing frame. A pointer is fixed on the shaft, and a dial plate with scale is fixed on the bearing frame. When the shaft rotates and drives the pointer to rotate, the data of the height of the liquid level can be displayed on the sedentary dial plate. The utility model has the advantages of simple structure, high safety, accurate metering and easy use. The utility model can be popularized in each oil depot and filling station.

Description

Horizontal oil tank level-meter

The utility model belongs to oil tank level height equipment, is specially adapted to underground or semi-underground horizontal tank.

Oil tank need constantly be measured liquid level in the process of transmitting-receiving oil, so that grasp a jar interior oil storage quantity at any time.Ullage rule is generally adopted in the measurement of existing oil tank oil storage quantity, open the gauging cap earlier, chi is inserted in the jar, measure, the not only danger but also dangerous of this method, the a large amount of effusion meeting of oil gas causes great harm to human body, therefore to horizontal tank, does not still have a kind of simple liquid level checkout equipment--liquid level gauge at present.

The purpose of this utility model is that design a kind ofly is applicable to general horizontal tank, particularly is applicable to the liquid level gauge of underground or semi-underground horizontal tank.

The purpose of this utility model is achieved in that fixes a bearing bracket stand on oil tank top, a rotating axle is housed on the bearing bracket stand, other has a float, float on the liquid level in the oil tank, with liquid level one lifting, be connected with the four-bar mechanism that a cover is made up of parallelogram between float and the axle, during the float lifting, axle rotated in positive and negative direction by four-bar mechanism.Fix a root pointer at axle head, fix the dial plate of a band scale on the bearing bracket stand, when axle rotates, drive pointer and rotate, on dial plate, show to change and hold the size at angle, thereby measure the height of tank level.Liquid level gauge can be made various models and specification, to be applicable to the oil tank of all kinds and capacity.

Advantage of the present utility model: simple in structure, safe and reliable, accurate measurement, easy to use.

Introduce structure of the present utility model and principle of work thereof in detail below in conjunction with accompanying drawing.

Fig. 1 is an overall construction drawing of the present utility model;

Fig. 2 is the A-A cut-open view.

Referring to Fig. 1, as seen from the figure, float (9) is with liquid surface lifting, motion between minimum level (14) and high liquid level (HLL) (15).One end of driving stem (8) is fixedlyed connected with float (9), and the other end and fixed bar (11) are hinged, and a hinge (10) is housed therebetween.A hinge (7) is arranged on the driving stem (8) in addition, and an end of connecting rod (6) and driving stem (8) constitute hinged with hinge (7).The other end constitutes hinged with hinge (5) and follower lever (4), the other end of follower lever (4) becomes fixedly connected with axle (3).Axle (3) is placed on the bearing bracket stand (13), can rotate on bearing bracket stand (13).Hence one can see that, and hinge (5.7.10) and spool (3) are four end points of parallelogram, form a four-bar mechanism, between bearing bracket stand (13) and base plate (12) and the fixed bar (11), is fixedly connected, all is fixed in oil tank top.

When float (9) during with liquid surface lifting, driving stem (8) is swung around hinge (10).Follower lever (4) is also done corresponding swing by connecting rod (6).Since between follower lever (4) and the axle (3) for fixedlying connected, so spool (3) rotate in bearing bracket stand (13).

Referring to Fig. 2, as seen from the figure the axle (3) the fixedly connected root pointer in end (2).Bearing bracket stand (13) is gone up the dial plate (1) with a band of screw (17) fixed installation scale.When axle (3) rotated with the lifting of float (9), pointer (2) correspondingly rotated.Because dial plate (1) is motionless, so pointer (2) indicates different number of divisions on dial plate (1), this number can reflect liquid level.16 is a dog screw among the figure, makes follower lever (4) become fixedly connected with axle (3).

Float (9) is used copper, is hollow-core construction.Remaining parts all adopts metal material to make, and also can all use oil resistant plastics to make.

Above-mentioned accompanying drawing and explanation thereof have provided embodiment of the present utility model.

Claims

1, a kind of horizontal tank liquid level gauge is characterized in that it is by forming with lower member:

A. float (9) that floats on liquid level.

B. one is placed on the pedestal (13) axle that can rotate (3) thereon.

C. overlapping the four-bar mechanism be made up of parallelogram with one between float (9) and the axle (3) links to each other.D. the four-bar mechanism of parallelogram composition comprises: a driving stem (8), the one end is fixedlyed connected with float (9), and the other end and fixed bar (11) are hinged with hinge (10), a fixed bar (11), fix with bearing bracket stand (13) and base plate (12), be installed on the top of oil tank.A connecting rod (6), the one end is hinged with hinge (7) and driving stem (8), and the other end is hinged with hinge (5) and follower lever (4).A follower lever (4), the one end is hinged with hinge (5) and connecting rod (6), and the other end becomes fixedly connected with screw (16) with axle (3).Hinge (5.7.10) and axle (3) are formed four end points of parallelogram.

E. one is installed on axle (3) end and the pointer (2) of fixedlying connected with axle (3).

F. the dial plate (1) of a band scale is fixed on the bearing bracket stand (13) with screw (17).

2,, it is characterized in that float (9) is made of copper hollow-core construction as the said liquid level gauge of claim 1.Remaining parts is made by metal material, also can adopt oil resistant plastics to make.
