Technical Field

[0001] The utility model relates to the field of sampling devices, in particular to an underwater water quality detection sampling device. Background Art

[0002] Underwater water quality testing refers to the process of measuring and analyzing the physical, chemical, and biological properties of water in an underwater environment. This testing is crucial for assessing and monitoring the health of water bodies, understanding the distribution and impact of pollutants, and formulating water resource management strategies. In the process of water quality monitoring, sampling devices are needed to collect water samples for subsequent analysis.

[0003] During the sampling process, existing sampling devices usually use a sampling container to extend underwater for sampling. Due to the different depths in different waters, the sampling container cannot accurately reach the predetermined water depth for sampling, resulting in the collected water samples not representing the actual water quality of the target water layer, reducing the accuracy of the sampling detection data.

[0004] Therefore, for the above-mentioned existing sampling devices, due to the different depths in different waters, the sampling container cannot accurately reach the predetermined water depth for sampling, resulting in the collected water samples not being able to represent the actual water quality of the target water layer, reducing the accuracy of the sampling detection data. An underwater water quality detection sampling device can be designed to record the depth changes during the dive, provide basic data for subsequent data analysis, and monitor the depth changes of the sampling tube at the same time, so as to facilitate timely adjustment of the diving depth and make adjustments according to different diving depths to adapt to different working environments and depth requirements.

A threaded head 210 is provided between the sampling tube 209 and the connecting plate 208. The sampling tube 209 is threadedly fixed to the connecting plate 208 through the threaded head 210. The sampling tube 209 can be replaced with the threaded head 210 according to the sampling requirements of different measurements to ensure sampling accuracy. At the same time, after the sampling is completed, the sampling tube 209 can be removed and the remaining sampling tubes 209 can be installed for secondary sampling, ensuring that the device can take multiple groups of samples in a short time and improving the detection accuracy. An electromagnetic valve 211 is provided on the outer wall of the sampling tube 209. One end of the electromagnetic valve 211 passes through the sampling tube 209 and extends to the interior. A feeding trough is provided at one end of the sampling tube 209. The sampling tube 209 is controlled by the electromagnetic valve 211. After reaching the target position, it is opened to collect samples, realizing remote control and automatic operation. It is quickly closed after sampling, reducing the contact time of the sample with the external environment and improving the sealing of the device.

[0024] See also Figure 1-Figure 3 In this embodiment, a positioning block 203 is provided at the outer end of the positioning wheel 205, and a cylinder 204 is provided at one end of the positioning block 203 away from the positioning wheel 205. A telescopic rod is provided at one end of the cylinder 204, which passes through the positioning block 203 and is fixedly connected to the positioning wheel 205. The sampling tube 209 is driven by the cylinder 204 to adjust laterally, so that the sampling tube 209 can be accurately positioned to the target water depth for sampling to meet specific sampling depth and operating conditions. A telescopic plate 202 is provided at the lower end of the positioning block 203, and a sleeve plate 201 is provided between the telescopic plate 202 and the supporting platform 1.

[0025] See also Figure 2-Figure 4In this embodiment, a control panel 214 is provided on the outer wall of the sleeve plate 201, and a transmission cable is provided at the outer end of the control panel 214.

By using the discharge pipe 213, the sample is directly guided to the designated collection container, which is convenient for the operator to collect and process the sample.

[0026] When working, first use the support table 1 to move the equipment to the designated placement position, use the telescopic rod to adjust the height of the sampling tube 209 along the inside of the sleeve plate 201, and after the height of the telescopic rod is adjusted, use the pin to insert the sleeve plate 201 to fix the telescopic plate 202.

After the cylinder 204 is telescopically adjusted, the sampling tube 209 is replaced with the threaded head 210 according to the sampling requirements of different measurements to ensure accurate sampling. After the sampling tube 209 is replaced, the telescopic ruler 206 connected to the rotating motor 207 is started to drive the sampling tube 209 into the water. In the process, the underwater depth of the dive is judged by the retractable ruler 206, and the depth changes during the dive are recorded to provide basic data for subsequent data analysis. At the same time, the depth changes of the sampling tube 209 are monitored to facilitate timely adjustment of the diving depth. Adjustments are made according to different diving depths to adapt to different working environments and depth requirements. After the sampling tube 209 reaches the specified position, the control panel 214 is used to control the electromagnetic valve 211 to open the sampling tube 209 to collect underwater samples, realizing remote control and automatic operation. After sampling, it is quickly closed to reduce the contact time of the sample with the external environment. The operating status and performance indicators of the sampling device are monitored in real time through the control panel 214, potential problems are discovered and handled in a timely manner, and sampling of samples at different water depths is realized.
