Abstract

The invention discloses a protective sleeve for fiber grating strain sensors, which comprises an outer shell. The cavity of the outer shell is movably connected with an inner shell. The front surfaceof the outer shell is fixedly connected with a fixed block. The front surface of the inner shell is fixedly connected with a locking block. The top and bottom of the cavity of the outer shell are fixedly connected with rotating shafts. Rotating shaft slots are respectively arranged in the top and bottom of the inner shell. The rotating shafts are matched with the rotating shaft slots. Through thecooperative use of the rotating shafts, a moving block, a first wedge block, a moving rod, a shifting block, a spring, a moving plate, a second wedge block, an inserting block, a sliding block, a movable hole, a movable frame and a clamping block, the problem that the existing protective sleeve is inconvenient to use is solved, users can replace a fiber grating strain sensor more conveniently, users can use the protective sleeve conveniently, and the practicability of the protective sleeve for fiber grating strain sensors is greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber gratings, in particular to a protective sleeve for an optical fiber grating strain sensor. Background technique [0002] Fiber grating is a kind of diffraction grating formed by axial periodic modulation of the refractive index of the fiber core by a certain method. It is a passive filter device. Because the grating fiber has small , can be embedded in smart materials, and its resonance wavelength is sensitive to changes in the external environment such as strain, refractive index, concentration, etc., so it has been widely used in the field of optical fiber communication and sensing. [0003] The protective sleeve of the optical fiber grating strain sensor is a tool applied to the optical fiber grating strain sensor. However, the existing protective sleeve is inconvenient to use. The practicability of the fiber grating strain sensor protective sleeve is improved. Contents of the inventio...
