Description

TECHNICAL FIELD

Floating monitoring station, with its advantages of not needing fixed shore support, can be flexibly deployed in the target water area, has become one of the mainstream equipment for real-time monitoring of water quality, which can realize the continuous collection and analysis of key indicators such as pH value, dissolved oxygen and pollutant concentration of water body.

[0003] However, the existing floating monitoring station for water quality detection still has many technical defects in actual application, which limits the accuracy and sampling efficiency of monitoring data: The traditional floating monitoring station mostly uses a single sampling device, which can only collect the water of a fixed water layer. If the water quality data of shallow and deep water areas are needed, the sampling device needs to be raised and lowered repeatedly, which not only is cumbersome to operate and has low sampling efficiency, but also easily disturbs the water body due to the movement of the device multiple times, resulting in the mixing of water samples of different water layers, which cannot truly reflect the vertical water quality distribution difference of the target water area, affecting the representativeness of the monitoring data.

[0004] The driving assembly of the existing monitoring station mostly uses ordinary motor with screw rod or rope transmission, which lacks high-precision limiting guide structure. Under the complex water environment such as water flow impact and wind wave disturbance, the lifting stroke of the sampling device is easy to deviate, resulting in the inconsistency between the actual sampling depth and the preset depth, and it is difficult to stabilize the positioning in the static state, further reducing the comparability of different batches of sampling data.

[0005] The water body is easy to stratify in natural state, and the temperature, solute concentration and suspended matter distribution of shallow and deep water bodies are different, and local water area may form uneven concentration due to pollutant settlement and biological activity. The existing sampling device mostly uses direct suction type collection without setting a water sample mixing mechanism, which is easy to collect local abnormal water sample, resulting in that the detection result cannot reflect the overall water quality condition of the water layer.

The following mainly introduces the working principle and process, and the specific work is as follows: The device is placed in the test area. The brake motor 221 drives the ball nut 224 to move downwards. The ball nut 224 drives the two sampling devices 3 to enter the water via the transmission block 23, the moving rod 24, and the baffle 25. When the brake motor 221 drives the two sampling devices 3 to enter the shallow water layer, the pressure sensor 36 in one of the sampling devices 3 reaches the specified water pressure. The pressure sensor 36 serves as the power source signal for the automatic water sampler 35 to start opening and closing for sampling. At the same time, the electric push rod 342 drives the automatic water sampler 35 to rotate and move to start sampling. It can accurately mix the water in the sampling area in a small range, and complete the mixing and sampling simultaneously, improving the representativeness of the water sample and the quality of water quality testing. After the automatic water sampler 35 finishes sampling, it is reset by the electric push rod 342 to complete the sampling of the shallow water in the test area.

[0026] Furthermore, the deep water body of the water body is detected. Similarly, the other sampling device 3 for deep water body sampling is driven by the brake motor 221 to the deep water body. Similarly, the pressure sensor 36 in the other sampling device 3 serves as the opening and closing signal of the automatic water quality sampler 35, and works with the electric push rod 342 to complete the sampling of the deep water body. Then, the electric push rod 342 is used to reset the sampler. Once the shallow and deep water samples from the target water area are collected, the two sampling devices 3 are reset by driving the brake motor 221, and the water quality can then be tested by the staff.
