Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: An environmental detection sampling device, such as Figure 1 As shown, it includes a sampling barrel main body 10, a weighted ring block 11 is fixedly installed on the lower end of the outer wall of the sampling barrel main body 10, and a mounting column 12 is evenly fixedly installed on the upper end of the outer wall of the sampling barrel main body 10. A connecting rope 13 is fixedly installed on the outer wall of the mounting column 12, and a hanging rope 14 is fixedly installed on the end of the connecting rope 13 away from the mounting column 12. Automatic switch components 15 are respectively provided at the upper and lower ends of the inner wall of the sampling barrel main body 10. By setting up the automatic switch component, the floating cover and the third engaging sealing tooth in the automatic switch component can automatically float up and disengage from the first engaging sealing tooth and the second engaging sealing tooth after the sampling barrel main body enters the water source, thereby opening for sampling. At the same time, when the sampling barrel main body rises, the floating cover and the third engaging sealing tooth automatically descend under the gravity of the water source and engage with the first engaging sealing tooth and the second engaging sealing tooth to achieve automatic closing, effectively avoiding contamination of the water source sample during the recovery process and improving the efficiency and effect of sampling.

[0029] Example 2: Based on Example 1, Figure 2 As shown, the sampling bucket body 10 includes a transparent sampling bucket 16, a first movable limiting groove 17 is provided at the upper end of the inner wall of the transparent sampling bucket 16, and a first engaging sealing tooth 18 is fixedly installed at the bottom of the inner wall of the transparent sampling bucket 16 at the first movable limiting groove 17, and the inner wall of the first engaging sealing tooth 18 is movably engaged with the outer wall of the automatic switch component 15, and a second movable limiting groove 19 is provided at the lower end of the inner wall of the transparent sampling bucket 16, a second engaging sealing tooth 20 is fixedly installed at the bottom of the inner wall of the transparent sampling bucket 16 at the second movable limiting groove 19, and the inner wall of the second engaging sealing tooth 20 is movably engaged with the outer wall of the automatic switch component 15. By providing a weighting ring block, the weighting ring block can increase the weight of the sampling bucket body, making it more stable when being put into use, and not prone to tilting or rolling, thereby further improving the accuracy and reliability of sampling.

[0030] Example 3: Based on Example 1 and Example 2, Figure 3As shown, the automatic switch assembly 15 includes a floating cover 21, and a third engaging sealing tooth 22 is evenly fixedly installed on the bottom of the floating cover 21, and the outer wall of the third engaging sealing tooth 22 is movably connected to the inner wall of the transparent sampling barrel 16, the outer wall of the third engaging sealing tooth 22 is movably engaged with the inner wall of the first engaging sealing tooth 18, and the outer wall of the third engaging sealing tooth 22 is movably engaged with the inner wall of the second engaging sealing tooth 20. By providing a connecting rope and a hanging rope, the connecting rope and the hanging rope can conveniently control the delivery and recovery of the sampling barrel body, the operation is simple and easy, and the difficulty of the sampling operation is reduced.

[0031] The working principle of the present invention is as follows: when it is necessary to carry out environmental detection sampling, first, the operator puts the sampling bucket body 10 into the predetermined water source through the connecting rope 13 and the hanging rope 14. Due to the weighted ring block 11 installed at the lower end of the outer wall of the sampling bucket body 10, the sampling bucket body 10 can remain stable during the putting process and is not prone to tilting or rolling, thereby improving the accuracy and reliability of sampling. As the sampling bucket body 10 is completely immersed in water, the internal automatic switch component 15 begins to play its role. Specifically, due to the buoyancy of the floating cover 21, it will automatically float up as the water level rises. When the floating cover 21 rises to a certain position, the third engaging sealing tooth 22 at its bottom will disengage from the first engaging sealing tooth 18 and the second engaging sealing tooth 20 on the inner wall of the transparent sampling bucket 16, thereby opening the top and bottom of the sampling bucket body 10, allowing water to enter the bucket for sampling. During the sampling process, the design of the transparent sampling bucket 16 allows the operator to intuitively observe the sampling The sampling situation is ensured, the accuracy and completeness of the sampling are ensured. At the same time, due to the design of the first movable limiting groove 17 and the second movable limiting groove 19, the floating cover 21 and the third engaging sealing tooth 22 can maintain a stable movement trajectory during the rising and falling process, further improving the reliability of sampling. When the sampling is completed, the operator recovers the sampling bucket body 10 from the water by pulling the connecting rope 13 and the hanging rope 14. During the recovery process, due to the gravity of the water source, the floating cover 21 will automatically drop, so that the third engaging sealing tooth 22 will engage with the first engaging sealing tooth 18 and the second engaging sealing tooth 20 again, realizing the automatic closing of the sampling bucket body 10. This design effectively avoids the contamination of the water source sample during the recovery process, improves the efficiency and effect of sampling, and realizes the automatic opening and closing function of the sampling bucket body through the design of the automatic switch component, thereby improving the efficiency and effect of sampling. At the same time, the design of the weighted ring block and the transparent sampling bucket further improves the accuracy and reliability of sampling.
