Abstract

The invention discloses a protection device of a wireless indicator diagram sensor of a pumping unit and belongs to the field of oil extraction equipment. The protection device comprises a protection cylinder and a protection box, wherein the protection cylinder and the protection box are connected in sequence. The protection cylinder is used for containing the transmitting end of the wireless indicator diagram sensor, the protection box is used for containing the pressure bearing end of the wireless indicator diagram sensor, and a polish rod of the pumping unit is sleeved with the protection box. An activating hole and a transmitting hole are formed in the protection cylinder, and the activating hole corresponds to an activator of the wireless indicator diagram sensor in position, and the transmitting hole corresponds to a transmitter of the wireless indicator diagram sensor in position. An activating hole plug is arranged on the activating hole in a matched mode, a transmitting hole plug is arranged on the transmitting hole in a matched mode, and both the activating hole plug and the transmitting hole plug are made of insulating materials. According to the protection device of the wireless indicator diagram sensor of the pumping unit, the transmitting end and the pressure bearing end of the wireless indicator diagram sensor can be effectively protected, and normal work of the wireless indicator diagram sensor is guaranteed; and using is convenient, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention relates to the field of oil extraction equipment, in particular to a protection device for a wireless power map sensor of an oil pumping unit. Background technique [0002] When using the pumping unit for oil production, in order to keep abreast of the underground working status of the oil pump deep in the oil well, it is necessary to install a wireless power map sensor on the polished rod of the pumping unit. The wireless power map sensor generally includes a pressure-bearing end and a transmitting end. The operation data of the polished rod of the pumping unit is collected through the pressure-bearing end, and then the collected data is transmitted to the analysis system in the computer through the transmitting end, so as to analyze the oil well pump. The operation status is monitored and analyzed in real time, and problems such as excessive gas and liquid leakage in the oil well are discovered in time, and corresponding maintenance and...
