When the water body is clear and the suspended substances are relatively less, the box body is opened from the right side (161 and 162), the sampling bottle is arranged at the sampling port (731) of the four-way shunt pipe, the drain port plug (733) is removed, a filter membrane meeting the experimental requirements is placed in the glass sand core filtering device (between 210 and 220), the box body is closed, the device is placed in water, the water body enters the first part in the box body from the wall surface of the perforated metal plate at the top of the box body, and can be discharged from the wall surface of the perforated metal plate at the same time, so that the water body is ensured to be in a flowing state, but a relatively stable environment is formed by the filter cup (210) of the glass sand core filtering device, preventing the filter membrane from being washed away or damaged by water flow. After the device reaches a preset position, the wireless remote control power supply controller (400) is utilized to start the circulating water pump (510), water samples are filtered, when the filtered water samples pass through the water inlet (520) of the circulating water pump, the remote liquid turbine flowmeter (600) starts to measure and calculate the volume of the filtered water samples, then the water samples enter the four-way shunt pipe through the water outlet (530) of the circulating water pump, at the moment, the water samples firstly enter the through-connected water outlet (720) and are discharged into the 3 rd part of the inside of the box body, one side of the bottom wall surface of the 3 rd part is a common metal plate (191), one side of the bottom wall surface of the 3 rd part is a rubber structure (192) with cross cracks, when the water sample is less in the box, only a small part of water sample can slowly permeate into the 4 th part in the box through the split, most of water sample still remains in the 3 rd part, and along with the increase of filtered water sample, the water sample can enter the sampling port (731) of the four-way shunt tube after filling the 3 rd part space, and the sampling bottle is filled, so that the volume of the filtered water sample is enough, the suspended matter (microorganism) sample collected on the filter membrane can reach the test level, and the shunt tube can be cleaned by the water sample filtered in the earlier stage, so that the water sample filled in the sampling bottle is not polluted or diluted. After 2 sampling bottles are filled, the 3 rd part in the box body is filled with the filtered water sample, and the water sample is forced to be flushed down by pressure along with the continuous filtration of the circulating water pump to form a cross split (192) on one side of the 3 rd partition rubber wall surface and enter the 4 th part in the box body. When the 4 th part in the box body is filled with the water sample, the water sample can also be forced to downwards rush out of the cross split of the rubber wall surface (163) part at the lower part of the right side wall surface of the box body under pressure and is discharged into a river, and meanwhile, the 4 th part is used as a partition, so that unfiltered water in the river can be prevented from flowing backwards and penetrating into the 3 rd part to pollute the filtered water sample. In the sampling process, the filtered sample volume can be observed in real time through the remote liquid turbine flowmeter (600), after the filtered volume reaches the experimental design requirement, the circulating water pump (510) is closed through the wireless remote control power supply controller (400), the device stops working, the device is retracted, in the retraction process, a first part of water sample in the box body can be discharged out of the device through the perforated metal plate wall surface, but a small amount of water sample can be reserved in the filter cup (210) of the filter device, and the filter membrane is ensured not to be polluted.

After the device reaches a preset position, the wireless remote control power supply controller (400) is utilized to start the circulating water pump (510), when the filtered water sample starts to be filtered and passes through the water inlet (520) of the circulating water pump, the remote liquid turbine flowmeter (600) starts to measure and calculate the volume of the filtered water sample, the water sample enters the four-way shunt pipe through the water outlet (530) of the circulating water pump, the water sample firstly passes through the through-connection water outlet (720), and the water sample enters the shunt pipe sampling port (731) due to the blocking of the outlet by the plug (733), and the sampling bottle is filled. At this time, the water sample in the earlier stage is firstly discharged out of the water outlet and the pipeline thereof, and the pollution or dilution of the water sample in the sampling bottle can be ensured to be less as much as possible. After the sampling bottle and the four-way shunt pipe are filled with water samples, the water samples can be flushed by water pressure to open a drain plug (733) and enter the third part, then the water samples penetrate into the fourth part in the box body, and finally the water samples are discharged into a river. Meanwhile, the 4 th part is used as a partition, so that unfiltered water in the river can be prevented from penetrating into the third part to pollute the filtered water sample. In the sampling process, the filtered sample volume can be observed in real time through the remote liquid turbine flowmeter, after the filtered volume reaches the experimental design requirement, the circulating water pump is closed through the wireless remote control power supply controller (400), the device stops working, the device is retracted, in the retraction process, a first part of water sample in the box body can be discharged out of the device through the wall surface of the perforated metal plate, but a small amount of water sample can be reserved in the filter cup (210) of the filter device, and the filter membrane is prevented from being polluted.
