Simple height indicator

Abstract

The invention relates to a measuring apparatus, in particular to a simple height indicator, which is characterized by being provided with a horizontal rod (1) with a level meter (2), one end of the horizontal rod (1) is provided with a goniometer (3) and hinged with a pointing pipe (5) capable of swinging by a pin roll and an optical sights with a through hole is arranged on the pointing pipe (5). Also a power supply, an angle sensor, a length sensor, an operating key (11), a single chip program-controlled module and a digital display (10) can be additionally provided. When the simple height indicator is used, the horizontal rod is laid flat near an object to be measured and the pointing pipe is swung to point at the top end of the object to be measured so that the height of the object to be measured is determined by a trigonometric function formed by the distance to the object to be measured and the corner of the pointing pipe as well as the height. The simple height indicator has the advantages of small volume, light weight, simple structure, low cost and easy operation, can measure the heights of a plurality of objects at close range, is convenient for carrying and is particularly suitable for being equipped and used in an ordinary laborer of a factory, a mine and the industries of power circuit maintenance, construction and installation and the like.

Description

technical field [0001] The invention relates to a measuring instrument, namely a simple altimeter. Background technique [0002] In engineering practice, we often need to know the height of certain objects, especially to judge the height without directly touching the object. For example: you need to know the height of a mountain without climbing, you need to know the height of a building without going upstairs, you need to know the height of a telephone pole without climbing a pole, etc. Of course, according to the current level of science and technology, it is not difficult to solve this problem. Using various advanced equipment that people have mastered, the height measurement of these objects can be well completed within a certain distance. However, these advanced equipments are relatively complicated, cost high, require high technical level of operators, and are inconvenient to carry, so it is difficult to equip a large number of junior personnel engaged in simple labor...

Problems solved by technology

In order to solve this problem, people have proposed a variety of methods without using equipment, such as using the shadow of the sun for judgment, using fingers for visual inspection, etc., but these methods have relatively large errors, and some require certain mental calculations, such as Pythagorean Theorems and other knowledge have certain requirements on workers' education level and computing ability, and the operation is relatively cumbersome, so they have not been popularized.
