Optical fiber sensor packaged by basalt fibers

Abstract

The invention discloses an optical fiber sensor packaged by basalt fibers, and relates to the technical field of optical fiber sensors. Included are a body and a connector, mounting plates are arranged at the front end and the rear end outside the main body; a buffer block is mounted in the mounting plate, a connecting wire is arranged at one end of the exterior of the main body, a limiting deviceis mounted at the exterior of the connecting wire, a connecting sleeve is arranged at one end of the interior of the connecting wire, a built-in wire is mounted in the connecting sleeve, and a protective frame is arranged at the top of the main body. The sensor has the advantages that a clamping plate, a fixed spring and a positioning plate are arranged; a limiting assembly can be properly adjusted according to the size of a connecting pipe; the structure is simple, operation is convenient, the clamping plate is properly adjusted through the elasticity of the fixing spring, the clamping plateand the positioning plate can wrap the connecting pipe, the connecting stability degree between the connecting pipe and the main body is increased, and normal use of the optical fiber sensor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of optical fiber sensors, in particular to an optical fiber sensor packaged with basalt fibers. Background technique [0002] Optical fiber sensor is a sensor that converts the state of the measured object into a measurable optical signal. The working principle of the fiber optic sensor is to send the light beam incident from the light source into the modulator through the optical fiber, and interact with the measured parameters outside the modulator to make the optical properties of the light such as light intensity, wavelength, frequency, phase, polarization state, etc. Changes, become a modulated optical signal, and then sent to the photoelectric device through the optical fiber, and the measured parameters are obtained after the demodulator. With the development of the times, the use of optical fiber sensors has become particularly important. [0003] The optical fiber sensors on the market are inconven...

Problems solved by technology

[0004] The object of the present invention is to provide an optical fiber sensor packaged with basalt fiber to solve the problem that the optical fiber sensor proposed in the background technology is inconvenient for the user to firmly limit the connection between the connecting line and the main body after installation, resulting in During long-term use, there will be poor contact between the connecting wire and the main body, which will cause inconvenience to the user, and it is inconvenient to protect the fiber optic sensor itself during use, and it is easy to damage the inside of the fiber optic sensor due to the external environment. Some of the buttons or display components cause damage, and there is no buffering effect on external forces
