During the descending process, the sensor integrated device monitors and feeds back the depth of the sampling device in real time. After reaching the specified depth, the specific sampling bottle for collecting water sample at this depth is determined by controlling the electromagnetic valve, and the sensor integrated device records and returns the temperature data of the water sample to the control center. After completing the water sample collection at the first depth, the lifting rope can be continuously released to realize water sample collection at different depths at the same location. After the sampling is completed, the rotating winch lifts the sampling device to the water surface. Through the sampling device, multiple water samples at different depths can be collected at one time, and the water samples are independent of each other and do not affect each other, which improves the sampling efficiency and accuracy.

After the water sample in the suction bottle is extracted, the normally open pipe clamp valve is opened, and the residual water sample in the suction bottle is discharged from the drain pipe, so as to avoid cross contamination of the water samples.
[0010] Further, the lifting device comprises a rotating winch and a winch support frame for supporting the rotating winch, the lifting rope is wound on the rotating winch, and a plurality of rope pressing devices are arranged on the periphery of the rotating winch and fixedly installed on the winch support frame.

[0015] Based on the above, opening the semicircular end cap can observe the inside of the sampling bottle, and the inside of the sampling bottle can be quickly flushed to ensure that there is no cross contamination in the sampling process and ensure the accuracy of the collected data. At the same time, the volume of the semicircular end cap is small, and it is easy to open, which avoids conflict with the upper structure of the sampling device.
[0016] Further, the sensor integrated device is internally provided with a temperature sensor and a depth sensor.
[0017] Based on the above, the temperature sensor is used for monitoring the temperature of the water sample collected at the current depth, and the temperature plays a significant role in the research of water quality. In the process of collecting water samples, the temperature of the water sample is easily affected by the outside world and changes, so real-time temperature data needs to be collected. The depth sensor is used for monitoring the depth of the water sample collected at the current depth, and transmitting data back to the control center.
