Example Embodiment

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0020] by Figure 1-10 It can be seen that the present invention includes a disc-shaped base 1 placed horizontally. The center of the upper end surface of the base 1 is provided with a fixed column 2 placed vertically, and the upper end surface of the base 1 is provided with a plurality of winding columns placed outside the fixed column 2 3. Each winding column 3 can rotate in one direction on the base 1. Multiple winding columns 3 are evenly distributed around the fixed column 2 with different thicknesses. The height of the fixed column 2 is higher than the winding column 3. , The outer circular surface of the fixed column 2 is provided with a plurality of annular grooves 4, and the plurality of circular grooves 4 are evenly arranged on the outer circular surface of the fixed column 2, and the number of the annular grooves 4 and the wi...

Abstract

The invention provides an optical fiber detection device, which effectively solves the problems that the existing device has single function and is inconvenient to use, the tension cannot be kept constant, and the measurement is unprecise due to uneven winding. According to the technical scheme, the optical fiber detection device comprises a base, wherein the upper end of the base is provided witha fixed column, the upper end surface of the base is provided with a plurality of wire winding columns which are positioned around the fixed column and have different thicknesses, a plurality of annular grooves are formed in the outer circumferential surface of the fixed column, the number of the annular grooves equals that of the wire winding columns, a tension device capable of rotating insideeach annular groove is fixed therein, and each wire winding column is provided with a pressing block corresponding to the height of the corresponding annular groove; and each tension device comprisesan arc-shaped block clamped in the corresponding annular groove, a rotatable supporting column is mounted on each arc-shaped block, a sleeve perpendicular to each supporting column is fixed on the supporting column, a first through hole is formed in the center of the sleeve, a plurality of clamping blocks are arranged inside one end of each sleeve, and each sleeve is internally provided with an adjusting column which can move along the axial direction of the sleeve. The optical fiber detection device is novel in concept and ingenious in structure.

Description

technical field [0001] The invention relates to the technical field of optical fiber detection, in particular to an optical fiber detection device. Background technique [0002] One of the most important advantages of optical fiber in common use today is its flexibility. Since the optical fiber is installed in different environments, the optical fiber must be able to bend to accommodate different bends; the result is that the condition of total internal reflection cannot be satisfied in the bent optical fiber, which means that a part of the light beam will go from the fiber to the fiber. Core escaped. Therefore, the optical power reaching the destination is less than the optical power emitted from the light source when it enters the fiber. The loss of optical power will occur after the optical fiber is bent. This is one of the most important reasons for the total attenuation of light propagating in the optical fiber; since there is no direct way to eliminate the cause of ...
