Indicator diagram collector of pumping well

Abstract

The invention discloses an indicator diagram collector of a pumping well. Two pressure-bearing heads are arranged at the upper end of a load body; a through slot, which corresponds to the pressure-bearing heads, is formed in the load body; a corresponding variant is arranged between one pressure-bearing part on the load body and the corresponding through slot; a supporting body is connected to the rear end of the load body; a groove is formed in one side at which the supporting body is associated with the load body; a circuit board and an acceleration chip and a communication module on the circuit board are arranged in the groove; a battery is arranged in a battery compartment in the supporting body; an antenna is arranged in an indicating window on the supporting body; a strain gauge, the battery and the circuit board are connected; the antenna is connected with the communication module; a rear cover plate is connected to the rear end of the supporting body; a transparent protective cover is arranged at the port of the indicating window. Two corresponding variants are adopted, so that the test precision is greatly improved; the circuit board, the acceleration chip and the communication module are arranged in the groove to be protected better; by virtue of the battery compartment, the supporting body is not dismounted during a battery changing process, and therefore, the problem that the test precision of load and displacement signals is lowered due to disturbance is avoided.

Description

technical field [0001] The invention relates to a work diagram collector, in particular to a work diagram collector for pumping wells. Background technique [0002] The basic composition of an existing pumping unit well power map collector is as follows: a pair of protruding pressure bearing heads are provided on the upper side of the load body with a "U"-shaped opening, and a through groove corresponding to the pressure bearing head is opened on the load body , a strain body is installed between each pressure head and the corresponding through groove on the load body, and a strain gauge is attached to the strain body, and a battery mounting frame is fixed in the rear cavity of the load body, and the battery mounting frame A fixed battery is installed on the top; the rear end of the load body is connected with a cover plate, and a circuit board is fixed on the cover plate. An acceleration chip and a wireless communication module are welded on the circuit board. The wires con...

AI Technical Summary

Problems solved by technology

The shortcomings of the pumping unit well power map collector mentioned above are: (1), the load test unit is two strain bodies, and the test accuracy is low; (2), the battery is installed on the load body, and the battery must be replaced when replacing the battery. The cover plate "concentrated body" is removed. During the removal process, it is inevitable to drive the load connector, circuit board, etc., so that the original calibrated load signal and the original calibrated acceleration direction may be disturbed, and the load and displacement signals. Disturbance will reduce the test accuracy, and it is very inconvenient to replace the battery in this way
