Battery device for downhole storage pressure gage

Abstract

The present invention relates to the technical field of pressure gages, especially to a battery device for a downhole storage pressure gage. The battery device comprises a sleeve made of plastic materials, the lower end of the sleeve is fixedly connected with a conductive plate, an iron sheet is fixedly connected with the bottom wall of the sleeve, the iron sheet and the conductive plate are connected through a conductive pole, the upper end of the iron sheet is fixedly connected with damping springs, a battery is put at the upper ends of the damping springs, the diameter of the battery is matched with the diameter of the inner cavity of the sleeve, a butting plate is butted against the upper end of the battery, the butting plate is provided with a limiting mechanism, the butting plate ismade of conductive materials, the section area of the butting plate is matched with the section area of the inner cavity of the sleeve, the butting plate is fixedly connected with a screw rod, the upper end of the screw rod is fixedly connected with a conductive disc, and the upper end of the screw rod is provided with a support mechanism. The battery device for the downhole storage pressure gagehas a protection effect on the battery and is convenient to replace the battery.

Description

technical field [0001] The invention relates to the technical field of pressure gauges, in particular to a battery device for downhole storage pressure gauges. Background technique [0002] An instrument for measuring fluid pressure. Usually, the measured pressure is compared with a certain reference pressure (such as atmospheric pressure or other given pressure), so that relative pressure or pressure difference is measured. [0003] According to different working principles, it can be divided into three types: liquid column type, elastic type and sensor type. Liquid column pressure gauges, such as U-shaped tube manometers and exhaust pipe manometers, convert pressure signals into liquid column height signals based on the principle of hydrostatics, and often use water, alcohol or mercury as the working medium for pressure measurement. The elastic type, such as the Bourdon tube manometer, converts the pressure signal into the mechanical deformation of the elastic element, a...

Problems solved by technology

[0004] When working in underground mines, it is necessary to use a pressure gauge to measure the pressure. Due to the harsh operating environment in the mine, the pressure gauge will often vibrate, which will cause the battery of the pressure gauge to loosen, resulting in poor contact, so that the pressure gauge cannot work normally. At the same time, it is not convenient to disassemble the battery and replace and charge the battery
