Abstract
The utility model relates to a mercury dip meter, including the vacuum cap, the vacuum tube, the mercury ball, stub and resistance wire, the vacuum tube is the arc vacuum tube of downwarping, be located inside the vacuum cap, the mercury ball sealing closes in the inside of vacuum tube, can be in the vacuum tube internal flow, the stub pastes the top at the inner wall of vacuum tube, the resistance wire pastes the bottom at the inner wall of vacuum tube, the mercury ball contacts with stub and resistance wire when the vacuum tube internal flow all the time, the length of stub and resistance wire slightly is greater than the length of vacuum tube, the stub is drawn forth from the one end of vacuum tube, the resistance wire is drawn forth from the other end of vacuum tube, the tip of drawing forth the end at stub and resistance wire do not is connected with a wire, the through -hole of the other end bottom the vacuum cap of wire is drawn forth to connect an external resistance on one of them wire. Only need during the use to fix this mercury dip meter on the testee, regularly measure the change volume of resistance value between the wire of drawing forth, can extrapolate the change value at inclination.
Description
Technical field
The utility model relates to a kind of mercury inclinometer, and utilize gravity to cause mercury bulb to flow and cause the change of instrument resistance, the object at inclination angle is measured in final realization.
Background technology
In productive life at ordinary times, often need the angle of inclination measuring some certain objects such as various buildings and each class A of geometric unitA, for small-sized object, usually manual measurement mode is taked, although it is convenient to measure, but need could obtain through complicated calculating the angle of inclination surveyed, and measuring accuracy is not high, for large-sized objects such as buildingss, manual measurement is obviously unrealistic, thus need to use inclinometer, but, existing inclinometer complex structure, expensive, install and use inconvenient, and seem " wasting one's talent on a petty job " when for measuring small-sized object.
Utility model content
The purpose of this utility model is to provide the instrument at the measurement inclination angle that a kind of structure is simple, precision is high, easy to install and use, cost is low, to overcome the defect existed in prior art.
For solving the problem, the utility model adopts following technical scheme:
A kind of mercury inclinometer, comprise vacuum (-tight) housing 1, vacuum tube 2, mercury bulb 3, stub 4 and resistance wire 5, vacuum tube 2 is reclinate arc vacuum pipe, be positioned at the inside of vacuum (-tight) housing 1, mercury bulb 3 is closed in the inside of vacuum tube 2, can in vacuum tube 2 internal flow, stub 4 is attached to the top of the inwall of vacuum tube 2, resistance wire 5 is attached to the bottom of the inwall of vacuum tube 2, mercury bulb 3 contacts with stub 4 and resistance wire 5 all the time when vacuum tube 2 internal flow, the length of stub 4 and resistance wire 5 is slightly larger than the length of vacuum tube 2, stub 4 is drawn from one end of vacuum tube 2, resistance wire 5 is drawn from the other end of vacuum tube 2, a wire is connected in the end of the exit of stub 4 and resistance wire 5, the other end of described wire is drawn by the through hole bottom vacuum (-tight) housing 1, and a wire connects an outer meeting resistance 6 wherein.
As further improvement, described vacuum tube 2 is fixed on the bottom of vacuum (-tight) housing 1 by two supports.
As further improvement, the outside surface of described vacuum (-tight) housing 1 is also enclosed with shell 7.
As further improvement, described vacuum (-tight) housing 1 is vacuum glass cover.
As further improvement, described vacuum tube 2 is glass tube with vacuum.
As further improvement, described shell 7 is opaque plastic casing.
As further improvement, the through hole bottom described vacuum (-tight) housing 1 is seal bore.
Mercury inclinometer of the present utility model only need be fixed in testee surface when using, or be embedded in testee inside, but two wires to be drawn, install and first measure the resistance between two wires with ohmmeter afterwards, only the changes values leading line resistance need be measured in the observation process of postorder, can extrapolate the changing value at inclination angle, be the instrument at the measurement inclination angle that a kind of structure is simple, precision is high, easy to install and use, cost is low.
Accompanying drawing explanation
