Problems solved by technology

Because the sampling water is turbid surface water, or other turbid environmental protection water, the water contains sand and other sundries, the sand entering the measurement chamber 52 seriously affects the accuracy of the instrument measurement signal, and damages the measurement chamber 52 and the lower piston 40. Surface roughness, causing drift in the measurement signal

Embodiment 1

[0015] It works like this:

[0016] See figure 2 : The present invention adds a sand trap 66 to the base 64 of the measuring chamber. When the sand in the sampled water enters the space 42 of the measurement chamber 52, it immediately falls into the sand trap 66, and stays in the trap 66 and cannot come out. The invention effectively avoids the influence of sand particles in the measurement water on the measurement signal, and protects the surface finish of the measurement chamber 52 and the lower piston 40 from damage. The sand is washed out of the trap 66 when cleaning the probe.

[0017] The present invention enables the measurement chamber base 64 to have two functions: (1) prevent the sample water from flowing out of the measurement chamber 52; (2) provide a sand trap.

Abstract

The invention relates to a novel design of a base of a measuring chamber of a streaming potential online sensor, particularly relates to improvement of a streaming potential online measuring apparatus, and discloses an additional sand trap of a base of a measuring chamber of a probe. The additional sand trap has the advantages that a base of a probe of an existing streaming potential online sensor is improved (is additionally provided with the base trap), so that sand which is fed into the measuring chamber of the probe can immediately fall into the base trap of the probe, influence of the sand on measurement signals can be eliminated, and the surface smoothness of the measuring chamber and a lower piston can be protected against damage.

Description

technical field [0001] The invention relates to a new design of the base of a swimming potential online sensor measurement chamber, in particular to a technology of adding sand traps to the base of the measurement chamber of the probe measurement chamber of a swimming potential online measurement instrument. Through the improvement of the current swimming potential online sensor probe base (adding base traps), the invention makes the sand particles entering the probe measuring chamber fall into the probe base trap immediately, eliminating the influence of the sand particles on the measurement signal, and at the same time protecting the measuring chamber and the The surface finish of the lower piston is not damaged. Background technique [0002] The swimming potential online sensor is a real-time measurement device, and the sampled water continuously flows through the sensor probe (inflow from the probe water inlet 14, and discharged from the probe water outlet 10). Since th...
