Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3The utility model provides an embodiment: a water sample collection device for water environment engineering detection, comprising a shell 1, the outer side of the shell 1 is rotatably connected with a connecting rod 3, the top of the connecting rod 3 is fixedly connected with a round rod 4, the inner bottom of the shell 1 is fixedly connected with a submersible motor 18, the output end of the submersible motor 18 is rotatably connected with a rotating block 13, the top of the rotating block 13 is fixedly connected with a sleeve 14, the middle of the sleeve 14 is slidably connected with a collection test tube 15, a top cover 2 is installed on the top of the shell 1, the top of the top cover 2 is fixedly connected with a pull rod 5, a through hole 8 is opened in the middle of the top cover 2, and a counterweight 19 is fixedly connected to the bottom of the shell 1.

[0026] When in use, under the action of the counterweight 19, the sampling device can fall straight to the bottom of the water. When the sampling device falls to different depths, the submersible motor 18 is driven to drive the rotating block 13 to rotate, so that the rotating block 13 drives the three sleeves 14 to rotate, so that the three sleeves 14 can respectively drive the three collection tubes 15 to rotate the bottom of the through hole 8 at different depths, so that water can flow into the middle of the collection tube 15 under the action of water pressure.

[0027] Reference Figure 1 and 2 A card block 11 is fixedly connected to the bottom of the top cover 2, a card slot 16 is opened in the middle of the outer shell 1, the card block 11 is slidably connected to the middle of the card slot 16, a sealing ring 17 is fixedly connected to the inner bottom of the card slot 16, a connecting assembly is installed on the outer periphery of the top cover 2, the connecting assembly includes a plurality of connecting blocks 6, and the plurality of connecting blocks 6 are respectively fixedly connected to the outer periphery of the outer shell 1 and the top cover 2, the middle parts of two adjacent connecting blocks 6 are slidably connected with bolts 7, the outer periphery of the bolts 7 is threadedly connected with nuts 12, the middle part of the outer shell 1 is fixedly connected with a drain port 9, and the middle part of the drain port 9 is fixedly connected with a valve 10.

[0028] During use, when it is necessary to take out a water sample, first turn the valve 10 to discharge the water in the outer shell 1 through the drain port 9, and then turn the nut 12 to remove it from the outer periphery of the bolt 7, so that when the pull rod 5 is pulled, the block 11 can be driven through the top cover 2 to slide into the slot 16, thereby preventing the water in the outer shell 1 from splashing into the collection tube 15 after the top cover 2 is removed, so that the collection tube 15 can be taken out to sample the collected water sample, and the collection tube 15 can be cleaned after being taken out, so as to clean the aquatic organisms and impurities attached to the inner wall of the collection tube 15, thereby ensuring the accuracy of the water sample used next time, and at the same time, under the action of the sealing ring 17, the sealing between the top cover 2 and the outer shell 1 is better and the connection is more stable.

[0029] Reference Figure 2-4A sealing gasket 24 is fixedly connected to the bottom of the top cover 2, a through hole 25 is opened in the middle of the sealing gasket 24, and the through hole 25 is connected to the through hole 1 8. A movable plate 23 is slidably connected to the middle of the sleeve 14, and a compression spring 20 is installed at the inner bottom of the sleeve 14. The collection tube 15 is in contact with the movable plate 23.

[0030] When in use, the collection test tube 15 is inserted into the middle of the sleeve 14, and then the block 11 at the bottom of the top cover 2 is inserted into the slot 16 and fixed by the bolts 7, so that the sealing gasket 24 at the bottom of the top cover 2 can push the collection test tube 15, so that the collection test tube 15 can push the movable plate 23 and squeeze the compression spring 20. After being squeezed, the compression spring 20 will push the movable plate 23 through the reverse thrust, so that the movable plate 23 pushes the collection test tube 15, and the tube mouth of the collection test tube 15 is fully fitted with the sealing gasket 24 to avoid the existence of a gap, so that after the collection test tube 15 rotates to collect water samples, the water flow poured into the outer shell 1 cannot penetrate into the collection test tube 15 through the gap, ensuring the preservation effect of the collection test tube 15 on the water sample after collection, and improving the accuracy of water sample inspection.

[0031] Reference Figure 4 A limit assembly is installed in the middle of the sleeve 14, and the limit assembly includes two slide bars 22. The two slide bars 22 are fixedly connected to the middle of the inner wall of the sleeve 14, and the outer periphery of the two slide bars 22 is slidably connected with a slider 21, and the slider 21 is connected to the movable plate 23.

[0032] During use, when the collection tube 15 pushes the movable plate 23 , the movable plate 23 drives the slider 21 to slide on the periphery of the slide rod 22 , thereby ensuring the sliding stability of the movable plate 23 .

[0033] Working principle: After the water sample is collected, the nut 12 is screwed and removed from the outer periphery of the bolt 7, so that the collection tube 15 can be taken out from the middle of the sleeve 14, so that the water sample in the collection tube 15 can be taken out for testing and the collection tube 15 can be cleaned, so that the inner wall of the collection tube 15 will not be attached with aquatic organisms or impurities, ensuring the accuracy of the next sampling of the collection tube 15.

[0034] After the collection test tube 15 is inserted into the middle of the sleeve 14, the top cover 2 is installed on the top of the shell 1. The top cover 2 will squeeze the collection test tube 15, so that the collection test tube 15 pushes the movable plate 23 and squeezes the compression spring 20. Under the reverse thrust of the compression spring 20, the mouth of the collection test tube 15 will fully contact the sealing gasket 24 to avoid the existence of gaps. After the collection test tube 15 is sampled, water cannot penetrate into the collection test tube 15 through the gap, ensuring that water samples in different collection test tubes 15 will not be mixed by water penetration, thereby improving the detection accuracy.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
