[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] This utility model provides an environmental engineering water sampling device, such as... Figure 1-4 As shown, it includes a connecting rope 2 fixedly connected to the top of the connector 1. A cylindrical rod 3 is fixedly installed at the top of the connecting rope 2 by a threaded cap. A hollow connecting rod 4 is threadedly installed at the bottom of the connector 1. A hollow connecting seat 5 is threadedly installed at the bottom of the hollow connecting rod 4. A water collection tank 6 is threadedly connected to the bottom of the hollow connecting seat 5. Multiple filter holes 11 are opened on the outer side of the bottom of the water collection tank 6.
[0025] In this embodiment, by setting a hollow connecting rod 4 and a hollow connecting seat 5, when water sampling is carried out, the water collection tank 6 installed at the bottom of the hollow connecting seat 5 can be smoothly lifted out of the water through the hollow connecting rod 4. When encountering aquatic plants and impurities, the water collection tank 6 can easily complete the sampling operation through the cooperation of the hollow connecting rod 4 and the hollow connecting seat 5, which can meet the needs of various complex aquatic environments.
[0026] The hollow connecting seat 5 has an inverted funnel-shaped structure. The water collection tank 6 is connected to the hollow connecting rod 4 through the hollow connecting seat 5. The outer side of the connector 1 is provided with an exhaust hole 7, which is connected to the hollow connecting rod 4.
[0027] In this embodiment, the hollow connector 5 is designed with a smooth, funnel-shaped outer surface, which facilitates its smooth removal from the water and avoids entanglement with aquatic plants. By providing an vent 7, air can be discharged from the vent 7 on one side of the connector 1 through the hollow connector 5 and the hollow connecting rod 4 when the water collection tank 6 is submerged in water for sampling. This allows water to enter the water collection tank 6 for sampling. The hollow connecting rod 4 can be connected in multiple sections as needed to ensure that the connector 1 is always above the water surface, facilitating normal venting of the vent 7.
[0028] A fixed plate 8 is fixedly installed on the inner side of the water collection tank 6. A fixed cylinder 9 is fixedly installed on the top of the fixed plate 8. A filter frame 12 is threadedly installed on the bottom of the fixed plate 8. A movable rod 14 is movably installed on the inner side of the filter frame 12. A cone block 10 is threadedly installed on the top of the movable rod 14. A limit ball 15 is fixedly installed on the bottom of the movable rod 14.
[0029] In this embodiment, by setting a filter frame 12, the water filtered through the filter hole 11 can be filtered a second time during the sampling process. After the water sample is collected and enters the water collection tank 6 through the fixed cylinder 9, it is convenient for the cone block 10 to contact and seal with the fixed cylinder 9, so that the water sample can be better stored in the water collection tank 6.
[0030] A fixed sleeve 13 is fixedly installed on the inner side of the filter frame 12. The movable rod 14 passes through the fixed sleeve 13 and is slidably installed with the fixed sleeve 13. The diameter of the limiting ball 15 is larger than the inner diameter of the fixed sleeve 13. The bottom circumferential surface of the cone block 10 contacts and seals with the top inner circular surface of the fixed cylinder 9.
[0031] In this embodiment, by setting up the cone block 10 and the fixed cylinder 9, when the water collection tank 6 is filled with water, the water enters through the filter hole 11 and is filtered by the filter frame 12 under the action of the gravity of this device, so that the water lifts up the cone block 10. After the sampling is completed, the cone block 10 contacts and seals with the fixed cylinder 9 during the lifting process, thereby storing the water sample in the water collection tank 6 for preservation.
[0032] Working principle: In use, first connect the connecting rope 2 to one end of the cylindrical rod 3 via the threaded cap. Then, thread the connector 1 at the bottom of the connecting rope 2 to the hollow connecting rod 4. Thread the hollow connecting rod 4 to the hollow connecting seat 5. Thread the hollow connecting seat 5 to the water collection tank 6. The operator holds the cylindrical rod 3 and lowers the water collection tank 6 into the water to take a sample. The bottom of the water collection tank 6 enters the water, and impurities in the water are filtered through the filter holes 11. After secondary filtration through filter frame 12, the water in the collection tank 6 is lifted by its own gravity, causing the water to pass through the fixed cylinder 9 into the collection tank 6 for collection. The gas in the collection tank 6 is discharged through the hollow connecting seat 5 and the hollow connecting rod 4 via the vent 7 on one side of the connector 1, facilitating the collection of water samples. After the water has submerged the hollow connecting seat 5, the collection tank 6 can be removed from the water. During this process, the cone block 10 will contact and seal with the fixed cylinder 9 to ensure that the water is stored in the collection tank 6, thus completing the sampling.
