Description

Technical Field

[0001] The invention relates to the technical field of water source sampling and detection, in particular to a water source sampling and detection device for geological survey. Background Art

[0002] When sampling and testing water sources in geological surveys, water sampling is generally carried out in groundwater environment detection wells. When sampling deeper water sources, the sampler is generally sent into the water by hanging for sampling. For example, a Chinese patent with authorization announcement number CN216247357U discloses a water source sampling and testing device for hydrogeological surveys, including a main frame. By setting a ratchet and a pawl, when the user collects water and takes samples, the device can stop immediately at any depth, thereby avoiding excessive sinking of the water collection device. By setting a float and a scale rope, the user can accurately judge the depth of the water collection device, thereby improving the accuracy of the sampling results and reducing the difficulty of operation.

[0003] When sampling water sources, the sample collecting device is extended into the water by pulling a rope, similar to the above-mentioned prior art. When sampling water sources at deeper locations in water environment detection wells, the sampling device needs to be extended into deeper water. In order to accurately sample water samples of an accurate depth, the water intake hole of the sampling device needs to be extended into a specific depth, and then opened for water intake through the cooperation of external detection equipment, a wireless transmitter and a controller, and then closed. The water environment detection well is in a state of having water for a long time, and more attachments are likely to accumulate on the upper layer of the water source. When the water intake device is placed in the water, attachments located on the upper layer of the water source are likely to adhere to the surrounding side of the water intake device. When the water intake hole is subsequently opened to take water, impurities in the upper layer are likely to enter, affecting water quality detection. Summary of the invention
