Description

Deflection tilt angle gauge

The present invention relates to a tilt angle gauge, and more particularly to a gauge that produces bending deformation for changes in the environment.

For earthquakes, geology, hillsides, earth rocks, bridges or houses and other environmental projects such as water and soil conservation, or the embedding of various pipelines and pipelines, due to various changes or deformations, it is often an overall environmental warning. However, because the above factors are buried below the surface, and the volume and range are very large, it is not easy to observe by visual observation when there is a slight change, or the lack of objectivity by visual observation.

Therefore, in the prior art, the tilting tube is first buried in the ground and then placed into a tilting sensor (IP) of about 50 cm in length, and the tilt angle of each tilting tube is measured, and finally tilted according to the tilting tube. The change in angle reverses the magnitude of the lateral movement of the inclined tube with the formation. However, this method requires manual measurement and the efficiency of the measurement is not good. Although electronic components have been used in recent years to replace manual timing measurement, electronic automatic monitoring tubes are expensive, susceptible to electromagnetic waves, and cause signal noise, and instruments and equipment are buried in the ground for a long time, which is susceptible to short-circuit or lightning strikes. problem.

More specifically, as disclosed in the Chinese Patent No. I250326 "Fiber Bending Tester", a sensor using a fiber Bragg grating element can be used to measure the angle of the structure skew or offset. The optical fiber is mainly composed of a fiber core and a cladding covering the fiber core. The refractive index of the fiber core is higher than the refractive index of the fiber shell, so that the light is made of a dense medium (high The total refractive index occurs when the refractive index region is transferred to the sparse medium (low refractive index region), so that the light is continuously propagated in the dense medium. The two ends of the fiber Bragg grating element of the prior art are respectively fixed in the base and the rotating end seat, and the fiber Bragg grating elements are respectively disposed on different surface sides of the connecting plate. The fiber extension extends from both ends of the fiber Bragg grating element and is exposed on the surface of the base and the rotating end seat, respectively, and each end face has a connector for serial connection. The prior art has a complicated mechanical structure, is not easy to manufacture, is expensive, and is susceptible to failure of the foreign object to catch the joint gap (and the fiber Bragg grating element and the fiber extension portion are not easily installed, and the two ends of the fiber Bragg grating element are They are fixed in the base and the rotating end seat respectively, so the bending angle of the two ends is limited, so that the market acceptance is not high.

After that, although the inventor designed a new Taiwan patent with a "tilt angle gauge" and approved the announcement as the new type M447983, the second segment can be made by a simple structure, especially the pivoting member. The first segment can be pivoted, and when the external environment (such as earth and stone) is bent, there is a compliant angle change, and the first segment and the second segment can form a protection for the first test strip. The mechanical structure and the manufacturing are relatively simple, and the installation is relatively easy, and the first measuring strip of the present case can make the second segment and the first segment pivotable under the pivoting member, and the bending angle can be relatively large.

However, with the new patent No. M447983, the inventor believes that there is still room for improvement, that is, although the second segment and the first segment can be pivoted, the bending angle can be relatively large, but it is too large. The bending angle can also cause the first strip to be excessively twisted to cause excessive deflection and damage. Moreover, the pivoting member is still insufficient for the universal change of the angle.

In view of the problems of the prior art, the inventors believe that there is a need to improve the foregoing, and accordingly, the inventors have devised a flexural tilt angle gauge comprising a first segment, the first segment being at least There is a first pipe, and a second segment, the second segment is at least a second pipe, the second pipe is in communication with the first pipe; a flexible connecting strip is connected between the first segment and the second segment, and the first pipe and the second pipe allow one The first test strip runs through.

The present invention has a simple construction, and in addition to retaining the advantages of the original novel, the present invention has a simpler structure, and the flexible connecting strip can cause "universality" between the second segment and the first segment. The deflection of the multi-directional direction has a compliant angle change when the external environment (such as earth and stone) is bent, and the first segment and the second segment can form a protection for the first test strip.

A phase grating that produces a periodic change in refractive index along the axial direction of the core to form a permanent space, which acts essentially to form a narrow band (transmissive or reflective) filter or mirror within the core. When a beam of broad-spectrum light passes through a fiber grating, the wavelength that satisfies the Bragg condition of the fiber grating will be reflected, and the remaining wavelengths continue to be transmitted through the fiber grating.

The short period fiber grating is called a Bragg Bragg Grating (FBG). That is, when the light propagating in the optical fiber encounters the short-period fiber grating, a certain resonant wavelength of light is coupled to a light that is reversely advanced (the modal propagation constant is negative) by the influence of the fiber grating, that is, incident. Light of this wavelength in the light produces a reflection effect at the short period fiber grating.
