Abstract
An analog device for measuring ocean engineering structure electric potential and the distribution is provided, which is provided with a reference electrode and a high input impedance voltmeter. The utility model is characterized in that: the reference electrode is connected on the axle of a slide wheel; the slide wheel is put in the groove of a guide rail; the axle of the slide wheel is connected with a rope and the both ends of the guide rail are fixed on a bracket. The utility model is a device having wide usages and measuring the electric potential value of each point on the measured objects and the change of the electric potential value with the space, which can provide sufficient experimental data to meet the requirement of the above design.
Description
Technical field
The utility model relates to a kind of test potential device, particularly relates to a kind of analogue means of testing oceanographic engineering structures current potential and distribution thereof.
Technical background
In the design of the corrosion and protection of oceanographic engineering structures, to the cathodic protection potential of structures and to be distributed with enough understandings extremely important.Existing potential testing device adopts potentiostat, multimeter or high input impedance voltage table usually, measures by two electrode systems or classical three-electrode system.But each electrode relative position of this device is fixed, current potential space distribution that can not the dynamic test measured object.Application number is to disclose a kind of corrosion potential distribution recognizer in 85101940 the Chinese patent, adopts microcomputer control step motor-driven scanning mechanism, and utilizes that microcomputer carries out the corrosion potential distribution measuring, data processing is stored and handle.This analyzer has higher scanning accuracy and automaticity, can be used for the research of metal corrosion and protection mechanism.Publication number is to disclose a kind of device with electrochemical method test or analysis of material in the patent of China of 1119739, it has M * N array electrode and reference electrode, array electrode draw termination multichannel analog switch, its output signal is transported to microcomputer after the A/D conversion, the control signal of microcomputer output connects the multichannel analog switch by digital I/O and level translator, but direct in-situ is measured the Potential distribution at metal/polymer interface.Above-mentioned disclosed two kinds of devices can both carry out the Potential distribution test, but their applicable object is single-minded, all are not suitable for the corrosion and protection design of oceanographic engineering structures, simultaneously the cost height.
Summary of the invention
The purpose of this utility model provides a kind of analogue means of testing oceanographic engineering structures current potential and distribution thereof, and it can overcome the above-mentioned shortcoming of prior art.
A kind of analogue means of testing oceanographic engineering structures current potential and distribution thereof, contrast electrode and high input impedance voltage table are arranged, it is characterized in that contrast electrode is connected on the axle of pulley, pulley is placed in the groove of guide rail, the axle of pulley is connected with rope, and the two ends of this guide rail are fixed on the support.
The utility model is a kind of each point potential value of the measurement testee with extensive use and the potential value device with spatial variations, and it can provide enough experimental data to satisfy the demand in the design.
Description of drawings and specific embodiments
Accompanying drawing is a structural representation of the present utility model.
The analogue means of this test potential and distribution thereof has contrast electrode 6 and high input impedance voltage table 7, it is characterized in that contrast electrode 6 is connected on the axle of pulley 4, pulley 4 is placed in the groove of guide rail, the axle of pulley 4 is connected with rope 5, the two ends of this guide rail 3 are fixed on the support 2, pulley 4 can move with pulley 4 in the groove of guide rail 3, and measures potential value and certain potential difference (PD) of 2 of measured object point exactly by the voltage table 7 of high input impedance.
When using the utility model, with tested structures for example steel pipe 1 be placed in the seawater of fixed support 2 belows, allow the lower end distance as requested of contrast electrode 6, such as 10 centimetres, near measured object, the other end of contrast electrode 6 is connected with the voltage table of high input impedance 7 one ends, another termination measured object steel pipe 1 of voltage table 7, measure a potential value, move the position of contrast electrode 6 by pulley 4, can record the potential value at place, any selected location, thereby draw out the potential difference (PD) of measured object current potential space distribution curve and any point-to-point transmission.
