Water resources need to be sampled and processed during water resource detection. Sampling is usually done through a sampling device. The existing sampling device is an instrument used for sampling during water resource detection. The sampling device is directly handheld during sampling. The rotating threaded push rod drives the piston to move to absorb the water resources for sampling. The sampling is simple and convenient. At the same time, the threaded push rod is smoothly rotated and adjusted, which improves the convenience of lubrication and movement of the threaded push rod during regular sampling operations.

[0003] When the existing sampling device is used to sample and detect water resources, the sampling device is embedded in water, and the threaded push rod is rotated inside the internal threaded hole to drive the piston to move inside the sampling tube. The piston is moved to extract the water resources to be detected into the sampling tube. Therefore, when the threaded push rod is rotated and moved inside the internal threaded hole for a long time, the threaded push rod is prone to slight instability during movement, which can easily cause internal friction and damage to the threaded structure, making it inconvenient to move and adjust the threaded push rod smoothly, making the sampling operation inconvenient, and affecting the convenience of lubrication and movement of the threaded push rod during regular sampling operations of the sampling device. For this reason, the utility model proposes a water resource sampling device. Utility Model Content

At this time, the threaded push rod 102 is held in hand to drive the threaded push rod 102 to rotate inside the internal threaded hole 107. When the threaded push rod 102 rotates, it drives the piston 106 to move inside the sampling tube 101, and when the piston 106 moves, the water resource inside the water body 103 enters the inside of the sampling tube 101 through the water inlet head 105, so as to facilitate the extraction of sampled water resources;

The elastic block 1044 is deformed to elastically clamp the clamp head 1043 inside the clamp hole 1042, and the filter screen 104 is clamped and fixed. Therefore, when the sampling device body 100 is used after installation, after the filter screen 104 and the end of the water intake body 103 are embedded in the water, if the surface of the filter screen 104 accidentally touches the surface of the internal object and causes damage, the filter screen 104 can be disassembled and replaced by the opposite operation, and the disassembly and replacement are convenient, which improves the convenience of disassembly and replacement of the sampling device body 100 when the filter screen 104 is damaged during sampling.
