It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1 and fig. 2, the device for quantitatively separating wigglers according to the embodiment of the present invention includes a first sample cell 1, a main flow channel 2 is connected to a lower end of the first sample cell 1, a first diversion channel 21 and a second diversion channel 22 are respectively disposed at another end of the main flow channel 2, the main flow channel 2 is provided with a counting unit 3, the first diversion channel 21 is provided with a first valve 4, and the second diversion channel 22 is provided with a second valve 5. Wherein, the counting unit 3 can be an ultrasonic counting device, a photoelectric counting device or a voice signal counting device, which counts by detecting the change of optical signals or voice signals when each wiggler passes through.

The device for quantitatively separating wigglers further comprises a second sample cell 6, wherein one side of the second sample cell 6 is provided with an overflow channel 61 communicated with the second sample cell, and the outlet of the overflow channel 61 is positioned above the inlet of the first sample cell 1.

Quantitative wiggler samples can be obtained through the following operations:

closing the first valve 4 and the second valve 5, and placing the wiggler sample into the second sample cell 6;

opening the first valve 4, then injecting water into the second sample cell 6 and the first sample cell 1, when the liquid level in the second sample cell 6 exceeds the inlet of the overflow channel 61, wiggler samples begin to overflow from the second sample cell 6 to the first sample cell 1, the wiggler samples begin to count when passing through the counting unit 3, and when the counting value reaches a preset value, a quantitative wiggler sample is discharged from the first diversion channel 21;

closing the first valve 4, zeroing the counting unit 3, then opening the second valve 5, discharging wiggler samples from the second diversion channel 22, starting counting the wiggler samples when the wiggler samples pass through the counting unit 3, discharging quantitative wiggler samples from the second diversion channel 22 when the counting value reaches a preset value, closing the second valve 5, and performing circulation operation to alternately obtain quantitative wiggler samples from the first diversion channel 21 and the second diversion channel 22.

It should be noted that, in order to ensure that the counting unit counts more accurately, the distance between the counting unit and the first valve 4 and the second valve 5 is minimum, and preferably, the counting probe of the counting unit is arranged in the first valve 4 and the second valve 5.

In order to improve the automation performance of the device, a water supply system for filling the second sample cell 6 and the first sample cell 1 with water is further included. The water supply system can be matched with liquid level meters in the second sample pool 6 and the first sample pool 1 for use, and water supply is suspended when the liquid level reaches a preset value, so that the function of automatic water supply is achieved.

Correspondingly, the first valve 4 and the second valve 5 are electrically connected with the counting unit 3.

The quantitative wiggler separation device further comprises a shell 7, the first sample cell 1 is arranged at the top of the shell 7, and the second sample cell 6 is also arranged at the top of the shell 7 and is positioned on one side above the first sample cell 1. The shell plays a better protection role.

In this embodiment, the second cuvette 6 is inclined in the direction of the first cuvette 1. So that the wiggler sample in the second sample cell 6 overflows to the first sample cell 1 more smoothly under the action of gravity.

Further, the overflow channel 61 extends from a side of the second sample cell 6 to the inlet of the first sample cell 1, and the radial dimension of the channel becomes gradually smaller along the extending direction thereof. So that the pressure of the water column flowing out of the overflow channel 61 is higher, and a certain stirring effect is achieved when the water column impacts the first sample cell 1.

Furthermore, a display screen is arranged on the shell 7, and is electrically connected with the counting unit and used for displaying the counting number.
