Reflection-type simple laser altimeter

Abstract

The invention discloses a reflection-type simple laser altimeter, comprising a reflector, a dial plate, a small counter weight, a reflector bracket, a laser emitter, an emitter bracket and a base plate. The emitter bracket is arranged on the base plate, and the left end of the base plate is provided with the reflector bracket as high as the emitter bracket; the dial plate is semicircular and provided with angle index, the center of circle of the dial plate is connected at the top end of the reflector bracket and can rotate around the same, the top end of the reflector bracket is further connected with the small counter weight through a string, and the reflector is arranged on the semicircular plane of the dial plate; and the laser emitter is connected on the top end of the emitter bracket and can rotate around the same. The reflection-type simple laser altimeter has the beneficial effects that estimated cost of the simple altimeter can be controlled within 100-200 yuan, price is relatively cheap, and the simple altimeter is also convenient to manufacture. In use, the altimeter is simple and convenient to carry during use, and precision of the altimeter also achieves the requirement on design precision of power 0.4kV door-to-door connection wires.

Description

Technical field [0001] The invention relates to a laser altimeter, more specifically, it relates to a reflection type simple laser altimeter for measuring the height of the household connection line or the house to the ground in the design of the 0.4kV household connection line of the electric power project. Background technique [0002] At present, there are four main methods for height measurement in power design: (1) GPS locator; (2) Theodolite or total station; (3) Hand-held infrared altimeter; (4) Large ruler or height measuring stick, flower Rod etc. [0003] GPS locator is troublesome to carry, because the measuring point cannot be placed high on the wall, it is impossible to measure the hanging height of the household connection line, and the price is expensive, more than 100,000 yuan. [0004] Theodolite or total station, the total station bracket is troublesome to set up, troublesome to carry, expensive, more than 30,000. [0005] Hand-held infrared altimeters are difficult...

AI Technical Summary

Problems solved by technology

[0003] GPS locator is troublesome to carry, because the measuring point cannot be placed on the high wall, so it cannot measure the hanging height of the household connection line, and the price is expensive, more than 100,000

[0004] Theodolite or total station, total station bracket setting is more troublesome, troublesome to carry, expensive, more than 30,000

[0005] Hand-held infrared altimeters are difficult to measure due to the influence of communication lines outside the wall, air conditioners and other equipment

[0006] It is troublesome to carry large rulers or height measuring sticks and flower poles, the measuring height is limited, and it is very difficult to measure above 9 meters

[0007] When measuring rural or urban overhead household connections, the above four methods are cumbersome or impossible to measure
