Description

Technical Field

[0001] This utility model relates to the field of water sample collection technology, and more specifically, to a water sample collection device. Background Technology

[0002] Water sampling and preservation refers to the process of collecting and preserving water samples from farmland ecosystems, including rainwater, irrigation water, runoff, and soil seepage water. These samples should be collected and preserved according to the requirements of the research. Rainwater can be collected from rain gauges at weather stations or placed in containers outdoors to collect samples during rainfall. Irrigation water should be collected in irrigation ditches or from water sources such as reservoirs, ponds, rivers, and wells. Avoid sampling from paddy fields that have been fertilized. Runoff water can be collected from the outlet of a runoff measurement facility. Soil seepage water can be collected by burying underground drainage pipes or using drainage samplers.

[0003] Currently, water sampling devices are an indispensable tool in water environment monitoring. Most existing water sampling devices can only sample the water surface. When dealing with water sampling at different depths, the device is usually filled with water from the surface and then dropped to the required depth. This makes it difficult to guarantee the accuracy of water sampling at different depths. Therefore, it is necessary to propose a water sampling device to solve the above problems.

During insertion, the distance between the sliding sleeves is determined according to the sampling depth using the first and second scale lines, and then fixed using locking devices. In this way, the collection tube is inserted into the water area to be sampled sequentially. Once positioned correctly, the air pump inflates the sampling tube, causing the float to rise and separating the second and first magnet rings. This allows water at the corresponding depth to enter the sampling tube. Then, the support and extension tubes are pulled upwards, sequentially pulling out the sampling tube. The control valve closes first, and the float, pulled by the connecting rope and the gravity of the second magnet ring, falls back and adheres to the first magnet ring for sealing. The sampling tube is then removed, and the locking mechanism is released to complete the sampling. This method allows for more accurate sampling at different depths and simultaneous sampling at multiple depths, improving accuracy and convenience. Attached Figure Description

[0032] Specifically, the working principle of this water sampling device is as follows: During use, the extension tube 120 is extended by connecting it to the first internal thread 111 via an external threaded tube 121. Then, the support tube 110 and extension tube 120 are positioned by passing through the guide tube 132. Next, multiple sliding sleeves 141 are fitted onto the support tube 110 according to different sampling depths. The threaded post 152 is rotated via the knob 153, causing the end of the threaded post 152 to press against the surface of the support tube 110 or extension tube 120, positioning the sliding sleeve 141 at the lower end of the support tube 110. The sampling cylinder 240 is then secured inside the elastic clamp 144.

Then, the support tube 110 and extension tube 120 are inserted into the water to be sampled. During insertion, the distance between the sliding sleeves 141 is determined according to the sampling depth via the first scale line 112 and the second scale line 123. The sampling tube 240 is fixed by locking member 150. Then, it is inserted into the water area to be sampled. Once inserted to the appropriate position, air pump 210 inflates the sampling tube 240. Under air pressure, the float 262 is pushed upwards, separating the second magnet ring 264 from the first magnet ring 263. Water at the corresponding depth enters the sampling tube 240. Then, the support tube 110 and extension tube 120 are pulled upwards. The sampling tube 240 is pulled out sequentially, first closing the control valve 251. Simultaneously, the float 262, pulled by the connecting rope 265 and under the gravity of the second magnet ring 264, falls back and adheres to the first magnet ring 263 for sealing. Then, the sampling tube 240 is removed, and locking member 150 is released to complete the sampling. This allows for more accurate sampling at different depths and simultaneous sampling at multiple depths, improving accuracy and convenience.

[0033] It should be noted that the specific model and specifications of the air pump 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
