Abstract

The utility model discloses a simple height measurer which is provided with a scale (1) with the length graduation and a scale (2) with the length graduation, and the scales are provided with an indicator tube (3) with an elbow or an indicator tube (4) with the elbow. The end part of the elbow is provided with an air valve (5) or an air valve (6), the indicator tubes (1), (2) are communicated by a communicating tube (9) positioned on the bottom end of the indicator tubes, and inner parts of the tubes (3), (4), (9) are filled with the indicating liquid with color. The device is especially suitable for the height measurement of the mountain area with larger height difference and the hilly area. The simple height measurer can not be restricted by the visual field and the visibility, and the simple height measurer has very convenient operation.

Description

Simple height measurer

The utility model relates to a kind of instrument of measuring height.

For a long time, the height that people generally use spirit-leveling instrument to carry out the face of land and object is measured, and this instrument price is expensive, operates cumbersome.(as occasions such as place such as forest, reed, careless boa, village, tunnel, Sui Dong, tunnel and night, dense fogs) uses very difficult under the situation of visual field difference and low visibility.

The purpose of this utility model is, a kind of simple and easy measurement of higher degree instrument is provided, and has to measure accurately, easy and simple to handle, is not subjected to the characteristics of the visual field or visibility restriction, and easy to manufacture, cost is low.

Technical solution of the present utility model is, it has the scale of two band length scales, its design feature is, an inditron of being with elbow is housed on every scale, the same caliber of two inditrons, the elbow end of inditron has air door, and two inditrons are connected by the connection flexible pipe that is connected on the bottom, inditron and be filled with indicator solution in communicating pipe.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings: Fig. 1 is a practical structures, and Fig. 2 is the indication tubular construction, and Fig. 3 is an elevation metering schematic diagram.In the accompanying drawings:

1,2--scale 3,4--inditron

5,6--air door 7,8--elbow

9--is communicated with flexible pipe

Referring to attached Fig. 1 and 2, the utility model has scale (1) and (2) of two strip length scales, the indicator tube (3) of band elbow (7) is housed on the scale (1), the indicator tube (4) of band elbow (8) is housed on the scale (2), and there is air door (5) termination of elbow (7), and there is air the termination of elbow (8) Valve (6) connects with being communicated with flexible pipe (9) respectively with the bottom of two indicator tubes (3) (4) of caliber, and two indicator tubes (3) (4) are communicated with. Be filled with indicator solution in indicator tube (3) and (4) and the described pipe (9).

For the purpose of easy to use, indicator solution in pipe (3) (4) highly is advisable (be communicated with flexible pipe (9) and also be full of by liquid this moment) to be charged to 1/2nd of liquid level arrival straight-tube portion (non-elbow part), and two scales (1) (2) should have common zero starting point.

Referring to Fig. 3, operation principle of the present utility model and using method are: because two scales are in differing heights, will keep again balance (same level height) with liquid level in two indicator tubes of caliber during use, then the relatively former scale of liquid level in each indicator tube will change. At this moment, actual measurement discrepancy in elevation a equals poor (b-c) of indicator solution scale of living on two scales. When once measuring greatly for fear of the discrepancy in elevation, the bottom that a scale occurs is higher than the top of another scale and makes the situation (liquid level in this moment another indicator tube be down to zero following) of the overflow of one of them indicator tube, should close earlier described valve (5) or (6) when carrying out this measurement, make the compressed and unlikely overflow of its top air because liquid level rises when this situation then occurring, after possibility is overflowed in eliminating, open again then described valve and normally measure.

This measuring instrument is measured accurately, makes and uses very convenient, easy, is not subjected to the restriction of the visual field, visibility, is particularly suited for mountain area and hilly country and uses, and work efficiency is high more a lot of than existing jack board.

Embodiment: wooden scale (1) (2) scale length overall is 1.5 meters, 0.5 centimetre of minimum calibrated dial, fill red water liquid and in glass inditron (3) (4), reach 0.75 meter scale place to liquid level, being communicated with flexible pipe (9) is 30 meters long rubber hose, and valve (5) (6) is the simple glass communicating valve.

Claims

1, a kind of simple and easy measurement of higher degree instrument, scale (1) and (2) that the strip length scale is arranged, it is characterized in that, be equipped with inditron (3) on the described scale (1), this inditron (3) has the elbow (7) of band air door (5), is equipped with inditron (4) on the described scale (2), and this inditron (4) has the elbow (8) of band air door (6), the connection flexible pipe (9) of inditron (3) (4) through being connected on its bottom is communicated with, and wherein is filled with indicator solution.
