Visual turbidity detection device and detection method thereof

A visual turbidity detection device, comprising:

• an observing box, comprising:
• a box;
• wherein the box defines an observing space inside;
• at least one side of the box defines an observing window, and at least one side of the box is capable of being disassembled from the box to define an opening to take and place a sample to be tested;
• an observing assembly, comprising:
• a first base and a first rotation shaft;
• wherein a first end of the first rotation shaft is rotatably connected to a bottom wall of the box, a shaft body of the first rotation shaft is fixedly connected to the first base, and a second end of the first rotation shaft extends out of a top wall of the observing box;
• the first base is configured to place the sample to be tested;
• the second end of the first rotation shaft is configured to rotate and drive the first base to rotate under drive of external forces, to make the first base rotate the sample to be tested to an observing position;
• and the observing window is facing towards the observing position;
• and
• at least one light assembly, configured to irradiate the sample to be tested in the observing position;
• wherein the at least one light assembly is disposed on an inner wall of the observing box;
• wherein the observing assembly further comprises:
• at least one test unit, and each test unit comprises:
• a second rotation shaft and a second base;
• in each test unit, the second base is rotatably connected to an upper part of the first base, a third end of the second rotation shaft is fixedly connected to the second base, the second rotation shaft is configured to rotate and drive the second base to rotate relative to the first base under drive of external forces, a fourth end of the second rotation shaft extends out of the observing box, and the second base defines at least one limit groove configured to place the sample to be tested;
• and
• wherein the at least one limit groove is a plurality of limit grooves, and the plurality of limit grooves are annularly arranged with the second rotation shaft as a center line;
• or wherein the at least one test unit is a plurality of test units, and the second rotation shafts of the plurality of test units are annularly arranged with the first rotation shaft as a center line.
