Problems solved by technology

Hand-held bayonet sensors are mainly used for oil field inspections, and the requirements for accuracy are not high. The main requirements are light weight and convenient installation. Calculating the force value of the strain signal has problems such as difficult control of the installation strength, low measurement accuracy, and a small range of available signals for acquisition.

Abstract

The invention discloses a hand-held bayonet sensor; the sensor is clamped on an oil pumping unit pull bar through a clamping slot and locked and fixed by a locking screw rod on one side; the sensor can use the thickening or thinning deformations of the oil pumping unit pull bar receiving force applications to measure the oil pumping unit pull bar received force, thus changing a conventional sensor measuring mode; a sensor force limit opening is set; when the locking screw rod is clamped to reach certain force value, the force limit opening is closed. The strain area receives a large initial force when a sensor is locked in the prior art, so the sensor mounting intensity is hard to control; the hand-held bayonet sensor can solve said problems, can reduce the sensor self measuring range, thus greatly improving the sensor precision; the collected available signal scope is tens of times bigger than before, so rear end treatments are convenient.

Description

Technical field [0001] The invention belongs to the technical field of sensors, and relates to a load sensor, in particular a handheld bayonet sensor. Background technique [0002] Existing bayonet sensors are mainly used in the field of oil fields. In the production process of coalbed methane and oil fields, to grasp whether the pumping unit system is working normally, it is generally divided into fixed bayonet sensors and handheld bayonet sensors. Hand-held bayonet sensors are mainly used for oilfield inspections. They do not require high accuracy. The main requirements are lightness and convenient installation. The main design ideas of the existing hand-held bayonet sensors are to use a large amount of time to ensure the installation strength, and then zoom in and out. The strain signal calculates the force value, which has problems such as difficult installation strength, low measurement accuracy, and small signal range available for acquisition. Summary of the invention [0...
