Description

Solid nonpolarizing electrode

Technical field

The utility model belongs to receiver and the probe that receives and transmit earth electric field information, is a kind of solid nonpolarizing electrode specifically

Background technology

Electrode is the key components in the monitoring earth electric field information measuring system, and it is widely used in fields such as the electrocatalyst precursor observation of earthquake ground, the exploration of geophysics electrical method, engineering geophysics, petroleum exploration, hydrogeophysical prospecting and telluric electromagnetic sounding.In existing work, generally use lead electrode or copper electrode, in the high-acruracy survey of some short time, also use unpolarizable electrode, as pertinent literature: " electrical measurement water detection " (geophysics mine locating group of Hebei province geology bureau, hydraulic and electric engineering publishing house, 1974.2, P174-176), reported that geophysics mine locating group of Hebei province geology bureau has made the lead chloride unpolarizable electrode in electrical measurement water detection, its manufacture method is after the galvanized wire immersion is contained 1% chemical pure Klorvess Liquid energising chlorination, become the lead chloride unpolarizable electrode, its difference in Electrode Potential is less than 10 millivolts." Ministry of Geology and Mineral Resources of People's Republic of China (PRC) DC electrical method job specification " (Geology Publishing House, 1984.10, P194-195), " electrical prospecting study course " (China Geological Univ metal physical prospecting teaching and research room, the Geology Publishing House, 1980.4, P546-547), reported the making of copper sulphate unpolarizable electrode, its difference in Electrode Potential is less than 2 millivolts; " telluric electromagnetic sounding research " (Chen Leshou, Liu Guodong, the Earthquake Press, 1984.6, P373-374) reported in the telluric electromagnetic sounding research, fixed station uses stereotype or lead wire net mostly, and the mobile unpolarizable electrode of using of measuring has: copper rod-copper sulfate electrode, cadmium rod-caddy electrode, silver-colored rod-silver chloride electrode.In all these electrodes, owing to exist lead electrode self current potential big, poor stability very easily changes with media environment; And problems such as useful life of other unpolarizable electrode such as copper sulphate short (several days or several months) and use inconvenience.So it is little that many in decades geophysics workers are devoted to develop a kind of extreme difference current potential always, the unpolarizable electrode that long-time stability are good, but for various reasons, this difficult problem never obtains fine solution.

The utility model content

The purpose of this utility model just provides that a kind of extreme difference current potential is little, stability good, noise is low, bandwidth, light durable, be easy to preserve, carry with easy to use, not only be suitable for flow measurement, but also can imbed the solid nonpolarizing electrode of underground long-term observation.

The utility model takes following technical scheme to solve its technical problem to be solved:

A kind of solid nonpolarizing electrode, form by electrode output line, heat-shrinkable T bush, lead rod and pvc pipe body, a block is established in described pvc pipe body upper end, pass an electrode output line on the block and insert in the pvc pipe body, the lower end of electrode output line connects a lead rod, outside suit one heat-shrinkable T bush of electrode output line, the junction suit one pyrocondensation insulated tube of electrode output line and lead rod; In the described pvc pipe body solid, shaped electrolyte is housed, plug in is established in pvc pipe body bottom, and interior plug middle part stays a passage, interior plug lower end to establish an outer plug, leaves the space between Nei Sai and the outer plug.

The utility model electrolyte is a solid, once assembling, the long-term use, have that the extreme difference current potential is little, stability good, noise is low, bandwidth, light durable, be easy to preserve, carry and characteristics such as easy to use.Both be applicable to open-air flow measurement, and can have imbedded underground long-term observation again, also can be used for deep-well, boring, ocean, electrical prospecting such as waterborne.

Technical indicator and performance characteristics:

" the solid nonpolarizing electrode stable performance, extreme difference satisfies the relevant specification requirement all the time between each electrode, has improved the quality and the operating efficiency of electrical prospecting to a certain extent.Solid nonpolarizing electrode can be used as the update equipment of former porcelain jar formula liquid unpolarizable electrode fully." (Gansu Province bureau of geology and mineral resources, " about the proof of solid nonpolarizing electrode effect "); Rotary island telluric electromagnetic sounding result of the test shows in Hainan, " solid nonpolarizing electrode can replace the copper sulphate unpolarizable electrode fully; all be better than the copper sulphate unpolarizable electrode at aspects such as the steady rate of short time, long stability, degree easy to use and reliabilities, do not have significant difference with French electrode." (Hainan Province seismological bureau, " solid nonpolarizing electrode test operation report ")." in Dunhuang-300 kilometers oil and gas pipes electrical prospecting of the southern Eight Immortals, by field work on the spot, kind electrode is compared with ceramic electrode, and following characteristics are arranged: 1, the electrode extreme difference is little for Gansu hydrogeology engineering geological investigation institute utilization solid nonpolarizing electrode; 2, stable performance; 3, easy to use, be easy to carry; 4, light durable, be easy to preserve.We with this unpolarizable electrode carried out 300 kilometers section swash electricity, from electrical measurement work, think that effect is better."
