Solar oil pumping unit well polishing rod load sensor

Abstract

The invention provides a solar oil pumping unit well polishing rod load sensor which comprises a load sensor. Outboard of the load sensor is fixed with a pedestal which is fixed with a pillar. An upper end of the pillar is fixed with a plug which is connected with a power supply terminal of the load sensor. A back of the solar energy cell is connected with a sleeve pipe which is provided with a socket inside. The socket is connected with a power supply output terminal of the solar energy cell. The sleeve pipe is in plug cooperation with the pillar, the plug and the socket respectively. Through the solar energy cell, power is supplied to the load sensor. When the solar energy cell needs to be replaced, the sleeve pipe and the pillar are separated, the plug and the socket are separated, and the solar energy cell can be detached conveniently without a mobile sensor. In addition, after cooperation of the sleeve pipe and the pillar and cooperation of the plug and the socket, relative rotation is available, thus adjustment of a solar orientation angle of the solar energy cell can be realized.

Description

technical field [0001] The invention relates to a load sensor, in particular to a load sensor for a polished rod of an oil pumping well. Background technique [0002] In the oil production operation of the pumping well, it is necessary to monitor the dynamometer diagram of the pumping well in real time. One of the important data collected by the power map is the load data of the polished rod of the pumping unit. At present, the wireless load sensor is used to obtain the load data of the polished rod of the pumping well, which gradually replaces the wired load sensor with the advantage of transmitting the collected data without wiring, and the wireless load sensor requires an independent power supply system as a guarantee Can work normally, there are currently two power supply methods for wireless load sensors: 1. Install a disposable large-capacity battery. After the battery is low, remove the sensor to replace the battery and reinstall it; Remove the sensor to charge it, ...

AI Technical Summary

Problems solved by technology

The above two power supply methods have the following disadvantages: after the battery is out of power, it is necessary to remove the sensor from the pumping unit, replace the battery or reinstall it after charging, the operation is cumbersome, time-consuming and laborious

In addition, for the former, waste batteries after replacement of disposable batteries need special recycling, otherwise many environments will cause great pollution
