Abstract

The invention discloses a depth meter which comprises a support and a meter ring. A connecting rod is arranged between the support and the meter ring, an insert needle made of hard alloy is arranged below the support, a display screen is arranged on the meter ring, and a button, a precision setting button, a clear button and a voice broadcasting button are sequentially arranged under the display screen. The depth meter which is a novel design scheme is simple in technology and skillful and novel in design, simple in structure, attractive in appearance, wide in service range and favorable for popularization, can be used for metering depth conveniently, can be applied to any environments, and can broadcast by voice automatically in a dark environment, so that flexibility in use is improved, automation degree is high, metering error is reduced, and production cost is saved.

Description

technical field [0001] The invention relates to the field of petroleum machining, in particular to a depth gauge. Background technique [0002] At present, in the process of oil extraction, some depth measurements are often carried out in order to know exactly how deep it is, and a lot of preparations should be made accordingly. However, if there is a ruler to measure, this method is cumbersome, and the error of the amount is too large. Large, so a depth gauge is needed. For example, the patent application document of Chinese application number 200410036196.6 discloses a depth gauge, which includes: a measuring rope used to be lowered into the measured body; Wheel surface; grating angular displacement sensor, the above-mentioned pulley drive is connected to the photoelectric code disc of the grating angular displacement sensor. Every time the pulley rotates one circle, the grating angular displacement sensor sends out two pulse signals of a selected number of either in-phase...
