A connecting pipe 307 is fixedly connected to the side of 302, a quick connector 306 is fixedly connected to the side of the connecting pipe 307, a solenoid valve 305 is fixedly connected to the side of the connecting pipe 307, and a water outlet pipe 303 is fixedly connected to the side of the water pump 301. Multiple connecting pipes 307 are set, and catheters of different lengths are connected to the connecting pipe 307 through the quick connector 306 to avoid placing the ends of the catheters in water at different positions. When sampling, one of the solenoid valves 305 is opened and the other solenoid valves 305 are closed. The water pump 301 is running to extract water from the position and transport it to the rotating mechanism 2 through the water outlet pipe 303. The solenoid valve 305 is closed, and the next solenoid valve 305 is opened to continue sampling. At the same time, the rotating mechanism 2 is running to transport the sample to the detection mechanism 4 for mutual detection.

[0023] The rotating mechanism 2 includes a base 201, the side of the base 201 is fixedly connected to the inner wall of the side of the housing 101, a mounting groove 213 is provided at the top of the base 201, a turntable 205 is movably sleeved on the side of the mounting groove 213, a stepper motor 212 is fixedly connected to the bottom of the base 201, the output shaft of the stepper motor 212 passes through the bottom of the mounting groove 213 and is fixedly connected to the bottom of the turntable 205, a mounting frame 206 is fixedly connected to the top of the turntable 205, and a mounting shaft is movably sleeved at the top of the mounting frame 206 corresponding to the position of the water outlet pipe 303 209, a detection cup 204 is fixedly connected to the side of the installation shaft 209, and the detection cups 204 with the same number as the connecting tube 307 are evenly distributed on the top of the turntable 205. During the sampling process, the detection cup 204 is located directly below the water outlet pipe 303, and the water sample falls into the detection cup 204 through the water outlet pipe 303. Then the stepper motor 212 is started to drive the turntable 205 to rotate, so that the next detection cup 204 moves to the bottom of the water outlet pipe 303 for sampling. At the same time, the detection cup 204 containing the sample moves to the bottom of the detection mechanism 4 for detection.

[0024] Among them, the bottom end of the installation groove 213 is movably connected to a roller 214 through a pin, and the top end of the roller 214 is transmission-connected to the bottom end of the turntable 205. The roller 214 supports the turntable 205. When the turntable 205 rotates, the roller 214 rolls along the bottom end of the turntable 205 to reduce the friction between the turntable 205 and the installation groove 213.

[0025] Among them, the top of the base 201 is fixedly connected with an annular guide rail 202, and the inner wall of the side of the annular guide rail 202 is provided with a slide groove 203.

[0026] Among them, a high-pressure nozzle 207 is fixedly connected to the side of the base 201, and a hot air nozzle 208 is fixedly connected to the side of the base 201. When the opening of the detection cup 204 moves downward to the position of the high-pressure nozzle 207, the high-pressure nozzle 207 sprays high-pressure pure water to rinse the detection cup 204, and then moves to the position of the hot air nozzle 208, and the hot air nozzle 208 blows out hot air to dry the detection cup 204.

The water pump 301 is operated to extract water at the position, and the water is transported to the inside of the detection cup 204 through the outlet pipe 303. After the sampling is completed, the solenoid valve 305 is closed, and the next solenoid valve 305 is opened to continue sampling. At the same time, the stepping motor 212 is started to drive the turntable 205 to rotate, so that the next detection cup 204 moves to the right below the outlet pipe 303 for sampling. When the detection cup 204 moves to the right below the detection probe 403, the automatic telescopic rod 402 pushes the detection probe 403 downward to make the detection cup 204 The probe 403 is inserted into the water inside the detection cup 204 for detection. At the same time, the limit column 210 slides in the slide groove 203 as the turntable 205 rotates. When the detection cup 204 after the detection is close to the front of the housing 101, the connecting rod 211 drives the installation shaft 209 to rotate to make the detection cup 204 flip over, and the sample inside the detection cup 204 is poured into the waste water tank 102. When it moves to the position of the high-pressure nozzle 207, the high-pressure nozzle 207 sprays high-pressure pure water to rinse the detection cup 204, and then moves to the position of the hot air nozzle 208. The hot air nozzle 208 blows out hot air to dry the detection cup 204, and then moves. When it is close to the position of the water outlet pipe 303, the detection cup 204 flips again so that the opening of the detection cup 204 faces upward. This is repeated to perform sampling and detection on multiple different positions.
