Optical fiber traction device for installing optical fiber sensor

Abstract

The invention discloses an optical fiber traction device for installing an optical fiber sensor. The device comprises a base. Two sliding grooves are formed in the top of the base in parallel. According to the invention, the pressing plate arranged on the lifting plate can drive the traction roller to clamp an optical fiber. During clamping, an elastic spring can provide certain elastic clamping for the pressing plate, and the damage of the optical fiber to the traction device during traction is weakened. Therefore, the service life of the traction device is prolonged. The bidirectional screwrod can be driven to rotate through the servo motor arranged at one end of the base. The two-way lead screw can drive the first sliding block and the second sliding block which are in threaded connection with the two ends to move relatively during rotation. When the first sliding block and the second sliding block move, the first lifting rod and the second lifting rod which are crossed between thebase and the lifting plate can be driven to perform crossed movement, so that the height of the lifting plate can be effectively adjusted, and the traction device is convenient to use.

Description

technical field [0001] The invention relates to an optical fiber pulling device, in particular to an optical fiber pulling device for installing an optical fiber sensor, and belongs to the technical field of optical fiber sensor installation equipment. 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. It changes and becomes a modulated optical signal, which is then sent to the optoelectronic device through the optical fiber, and the measured parameters are obtained after the demodulator. During the whole process, the light beam is introduced through...

AI Technical Summary

Problems solved by technology

When the existing optical fiber pulling device is in use, since the optical fiber is a whole section, the impact force and vibration generated by the optical fiber during pulling are relatively large, resulting in a short service life of the pulling device. At the same time, the existing pulling device Cannot adjust the height of the tow while working
