Vertical height-transmitting instrument

Abstract

The invention discloses a vertical height-transmitting instrument, which comprises an upper device (1) and a lower device (2), wherein the upper device (1) is provided with a first rectangle frame body (11); the lower device (2) is provided with a second rectangle frame body (21); a steel rod (13) and an aluminum rod (14) are fixed at the lower end of the upper device (1); the other end of each of two stainless steel wires is fixed on a cross rod (18) through a connector (19); and one end of the cross rod (18) is fixed in the side wall of the second rectangle frame body (21), and the other end of the cross rod (18) is fixed with a heavy weight (20). By the vertical height-transmitting instrument, the defects that the conventional monitoring methods such as a level observation method, a precise pitch measuring method and the like are limited to a great extent and are low in accuracy are overcome, field condition limitation can be effectively eliminated, and the problem that the conventional measurement method cannot be performed due to condition limitation; and accuracy can reach + / -0.1 millimeter and observation accuracy is greatly improved.

Description

technical field [0001] The invention relates to a vertical altimeter, which belongs to the field of safety monitoring. It is a special instrument used to regularly monitor the elevation difference between two points at different elevations on the same vertical line and its change. The instrument can also be used to transfer elevations from one elevation surface to another in one pass. Background technique [0002] In the vertical displacement monitoring of large-scale water conservancy projects, the elevation difference change monitoring between two points at different elevations on the same vertical line will be affected by external conditions such as no connecting channel between the upper and lower elevation surfaces, large temperature changes between the upper and lower elevation surfaces, etc. , the traditional monitoring methods such as leveling observation, precision distance measurement, etc. are greatly limited, and the accuracy is low.

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problem that the elevation difference change monitoring between two points on different elevation surfaces on the same vertical line is easily restricted by field conditions, and the temperature of the upper and lower elevation surfaces changes greatly, which affects the monitoring accuracy. Poor monitoring can effectively get rid of the limitation of on-site conditions, completely eliminate the influence of temperature, and greatly improve the monitoring accuracy
