Tension stabilizing device for probe waveguide wire

Abstract

The invention discloses a tension stabilizing device for a probe waveguide wire, and belongs to the technical field of petroleum detection. The device comprises a bearing piece, an installation guiding piece, an elastic piece, a lead, the waveguide wire and a waveguide wire fixing assembly, wherein the installation guiding piece is inserted in one end of the bearing piece, and the elastic piece and the waveguide wire fixing assembly are both arranged in the installation guiding piece; the elastic piece is provided with an axial leg and an electrical connection part, the waveguide wire is arranged on the bearing piece and penetrates through the elastic piece to be in contact with the axial leg, and the contact portion of the axial leg and the waveguide wire penetrates through the waveguidewire fixing assembly; the wire is arranged on the bearing part and extends towards the elastic piece to be electrically connected to the electrical connection part of the elastic piece. According to the device, when the external environment changes, tension exerted on the waveguide wire can be stably linearly changed through the elastic piece, then signals can be stably transmitted, and the measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of oil detection, in particular to a tension stabilizing device used on probe waveguide wires. Background technique [0002] At present, in the gasoline retail industry, the equipment used to measure or measure the oil in the tank has been widely used. Compared with the manual measurement method, the measurement equipment or metering equipment has the advantages of safety, accuracy and remote online management. Measuring equipment or metering equipment such as probes, which send electrical signals on the waveguide wire at a rated rate, and when they encounter a magnetic material, a signal will be reflected, and the original transmitted signal will continue to move forward, and finally return along the loop, so that Determine the required time parameters, and then calculate the liquid level height. At present, there are relatively few probes with stable and high-precision liquid level measurement, and these ...

AI Technical Summary

Problems solved by technology

At present, there are relatively few probes with stable and high-precision liquid level measurement, and these probes will drop the line and jump the liquid level when the ambient temperature changes greatly or the vibration is strong. The reason for this failure is due to The pulling force of the waveguide wire cannot be returned or stuck after the ambient temperature changes, resulting in disconnection or liquid level jumps, which ultimately affects the measurement accuracy of the oil in the tank
