Abstract
The utility model discloses a circular deformation measurer, comprising a circle measuring circuit, an ampere meter, a switch and a power supply, etc., wherein the circle deformation measurer is used for measuring the circle deformation amount of a cylinder, etc., the wires in a circle measuring circuit is prepared by a material with excellent flexibility and with resistance greatly changing with deformation, and the circle measuring circuit is arranged on the cylinder, etc., to detect and calculate the deformation amount of the cylinder through detecting current change by using the ampere meter, thereby being simple in structure, and novel and convenient in use.
Description
Technical field
The utility model relates to a kind of distortion measurement appearance, relates in particular to a kind of circular distortion measurement appearance.
Background technology
In the building, have a lot of places to need cylinder or elliptic cylindrical as support now, often these pillars play important effect, and we need pay close attention to and detect to prevent unexpected the generation it.
Therefore, ad hoc meter the utility model.
The utility model content
The purpose of the utility model is to provide a kind of circular distortion measurement appearance; Comprise circular metering circuit, reometer, switch, power supply; Be used to measure the circular deformation quantity of cylinder etc., the lead in the circular metering circuit adopts and is easy to flexible and resistance changes material greatly with deformation, partly is positioned over circular metering circuit on the column structure; The deformation quantity that changes this cylinder through reometer detection electric current detects, and the technical scheme of the utility model is following:
A kind of circular distortion measurement appearance; Form by circular metering circuit, reometer, switch, power supply electrical connection; It is characterized in that: circular metering circuit partly is positioned on the column structure, and the current change quantity that detects circular metering circuit through reometer detects the circular deformation quantity of column structure.Lead employing in the said circular metering circuit can be stretched and resistance changes material greatly with deformation.Implementation step comprises:
On A, the cylinder that circular metering circuit is detected around needs;
B, CC, the observation electric current changes;
C, if electric current is 0, explain that cylinder is damaged, if electric current changes, explain that cylinder is out of shape in contraction or expansion or certain direction, and can calculate deformation quantity through formula.
Among the said step C, wherein change in current is mainly confirmed circular deformation quantity by the law of resistance (law of resistance), and formula is R=pL/S.P wherein: process the resistivity of material of resistance, L: turn to the conductor length of resistance, S: the conductive wire cross-section that turns to resistance is long-pending, R: resistance value can calculate the coefficient of long-range contraction or expansion according to this while.
The beneficial effect of the utility model: a kind of instrument of measuring circular deformation that is provided, simple in structure, be easy to realize, easy to use and be easy to the exploitation of upgrading on this basis.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, will carry out comparatively detailed explanation to the preferred embodiment of the utility model.
It is as shown in Figure 1,
The concrete steps that the utility model is realized are following:
On step 1, the cylinder that circular metering circuit (1) is detected around needs;
Step 3, if electric current (2) is 0, explain that cylinder is damaged, if electric current changes, explain that cylinder is out of shape in contraction or expansion or certain direction, and can calculate deformation quantity through formula.
In step 3, wherein change in current is mainly confirmed circular deformation quantity by the law of resistance (law of resistance), and formula is R=pL/S.P wherein: process the resistivity of material of resistance, L: turn to the conductor length of resistance, S: the conductive wire cross-section that turns to resistance is long-pending, R: resistance value can calculate the coefficient of long-range contraction or expansion according to this while.。
Should be understood that; Above-mentioned description to embodiment is comparatively detailed; Can not therefore think restriction to the utility model scope of patent protection; Variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
