Abstract
The invention relates to improvement of a probe of a streaming potential online measuring instrument and in particular relates to a novel design of a water inlet and a water outlet of a probe as improvement of a streaming potential online measuring instrument. The probe comprises a probe water inlet, a probe water outlet and a measuring chamber, wherein sand grains are sent into the probe along with sampling water from the probe water inlet to move in a parabolic manner; in the design of a registered streaming potential online measuring instrument, the water inlet and the water outlet of the probe are arranged on the same horizontal line; the fed sand grains are incapable of being discharged out of the outlet and enter the measuring chamber of the instrument, thus measuring signals are seriously interfered; according to the design, the horizontal line of the probe water outlet is lower than the horizontal line of the probe water inlet by a certain distance, so that the sand grains moving in the probe in the parabolic manner can be discharged out of the probe water outlet to ensure that the sand grains are incapable of entering the measuring chamber of the instrument, thereby ensuring accuracy and stability of the measuring signals of the instrument.
Description
Technical field
The present invention relates to the improvement of streaming potential on-line measurement instrument probe, relate in particular to a kind of streaming potential on-line measurement instrument and improve---probe water inlet and water delivering orifice newly design.The present invention, by improving water inlet and the water delivering orifice design of streaming potential on-line measurement instrument probe, effectively avoids the foreign material such as the grains of sand to enter probe measurement chamber, improves the Stability and dependability of streaming potential on-line measurement apparatus measures signal.
Background technology
Streaming potential on-line measurement instrument is real-time measurement apparatus, sample water continuously by surveying instrument pop one's head in (sample water from probe water inlet flow into, from probe water delivering orifice discharge).Because sample water is muddy surface water, or other muddy environment-protective waters, the foreign material such as the grains of sand in water, contained.
Streaming potential principle shows, the residual charge in this commercial measurement sample water, the foreign material interferometry signals such as the grains of sand.The grains of sand that enter measuring chamber have a strong impact on the accuracy of apparatus measures signal, and the smooth finish on damage measurement chamber and lower piston surface, cause measuring-signal to produce drift.
Summary of the invention
1, technical matters to be solved
Existing streaming potential on-line measurement instrument has the following disadvantages: the grains of sand that enter measuring chamber have a strong impact on the accuracy of apparatus measures signal, and the smooth finish on damage measurement chamber and lower piston surface, causes measuring-signal to produce drift.
2, technical scheme
In order to overcome the above problems, to the invention provides a kind of streaming potential on-line measurement instrument and improve---probe water inlet and water delivering orifice newly design, and comprising: probe water inlet 14, probe water delivering orifice 10, measuring chamber 52.The present invention is according to physics level throw motion principle, and the object on desktop is subject to after horizontal thrust, is subject to the superposition of gravity and impulse force after it leaves desktop simultaneously, and this object is done trajectory motion, as shown in Figure 1.
The grains of sand are made level throw motion with sample water from probe water inlet is injected probe, in registered streaming potential on-line measurement Instrument Design, owing to popping one's head in water inlet and water delivering orifice on same horizontal line, the grains of sand that enter cannot be discharged from outlet, to enter the measuring chamber of instrument, severe jamming measuring-signal.The present invention designs probe water delivering orifice horizontal line lower than probe water inlet horizontal line certain distance, and the grains of sand of making level throw motion in probe can be discharged from probe water delivering orifice.
3, beneficial effect
The present invention utilizes level throw motion principle in physics to improve existing streaming potential on-line measurement instrument probe design, the grains of sand that enter from probe water inlet are discharged from probe water delivering orifice, guarantee that the grains of sand do not enter the measuring chamber of instrument, thereby guarantee accuracy and the stability of apparatus measures signal.

Embodiment
Below by embodiment, the present invention is described in detail.
Embodiment 1
Its working method is as follows:
According to level throw motion principle, the present invention will pop one's head in water delivering orifice 10 horizontal lines reduce, make it lower than probe water inlet 14 horizontal line certain distances, effectively the foreign material such as the grains of sand of injecting from probe water inlet 14 with sample water are discharged from probe water delivering orifice 10, guarantee that probe measurement chamber 52 is interior without foreign material such as the grains of sand, thereby guarantee accuracy and the reliability of streaming potential on-line measurement apparatus measures signal.
