Solar battery wireless inclinometer

摘要

An inclinometer that provides inclination data of a walking beam in a rod pumping system includes a cover including an indented portion external to the inclinometer. The cover is attached to a chassis which together provide an internal area. Magnets are attached to a bottom of the chassis to magnetically attach the inclinometer to the walking beam. A power supply within the internal area includes a power storage and a charger. A solar panel is disposed in the indented portion of the cover and electrically connects to the power supply through a hole in the cover. Beam angle sensor circuitry measures an inclination of the walking beam and transmits corresponding inclination measurement data via an antenna in the internal area. The power supply is configured to supply power to this beam angle sensor circuitry.

1. An inclinometer to provide inclination data of a walking beam in a rod pumping system, the inclinometer comprising:
a cover including an indented portion external to the inclinometer; a chassis, the cover attached to the chassis, and the cover and the chassis providing an internal area of the inclinometer; one or more magnets attached to a bottom of the chassis and configured to magnetically attach the inclinometer to the walking beam; a power supply within the internal area of the inclinometer and including a power storage and a charger; a solar panel disposed in the indented portion of the cover and electrically connected to the power supply through a hole in the cover; an antenna, wherein the antenna is within the internal area of the inclinometer; beam angle sensor circuitry configured to measure an inclination of the walking beam and transmit corresponding inclination measurement data via the antenna, wherein the power supply is configured to supply power to the beam angle sensor circuitry; and a magnetic switch within the internal area of the inclinometer and disposed at a side of the cover, the magnetic switch configured such that the power supply is connected or disconnected to the beam angle sensor circuitry by placement of a magnet at a location exterior to the inclinometer corresponding to the interior location of the magnetic switch.
