[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example 1: Water sample collection device, such as Figures 1 to 5 As shown, it includes an installation plate 1, a float 2 at the bottom of the installation plate 1, a support frame 4 fixedly connected to the top outer wall of the installation plate 1, a fixed plate 3 connected inside the support frame 4 through a lifting mechanism, a collection box 6 connected to the bottom of the fixed plate 3 through a connecting component, and a partition plate 7 dividing the inside of the collection box 6 into multiple sampling chambers.

[0024] The connecting assembly includes a fixing bolt 8 and a connecting block 9. The fixing bolt 8 is threaded to the top outer wall of the collection box 6, and the connecting block 9 is fixedly connected to the top outer wall of the partition plate 7. The connecting block 9 is inserted into the fixing plate 3. The bottom end of the fixing bolt 8 is threaded to the connecting block 9. The bottom outer wall of the fixing plate 3 is provided with a slot 10. The side wall of the collection box 6 is inserted into the slot 10 for limiting. The inner wall of the slot 10 is provided with a sealing ring 11 for sealing.

[0025] A rotating plate 15 is rotatably connected to the top outer wall of the fixed plate 3. A gear ring 16 is fixed to the side wall of the rotating plate 15. A drive gear 17 is provided inside the fixed plate 3. The drive gear 17 and the gear ring 16 are meshed in transmission. A drive mechanism for driving the drive gear 17 to rotate is provided on the top of the fixed plate 3. A plurality of sampling holes 18 are opened on the top of the fixed plate 3, which are respectively connected to a plurality of sampling chambers. A through hole is opened on the top outer wall of the rotating plate 15. A sensor for determining the rotation angle of the rotating plate 15 is provided on the top of the fixed plate 3.

[0026] The lifting mechanism, drive mechanism and other electrical components are all electrically connected to the controller. The controller can be an existing device such as a computer that provides control. The mounting plate 1 is equipped with a power supply module for power supply.

[0027] During sampling, the device is placed on the water surface. The lifting mechanism lowers the fixed plate 3 and the collection box 6. When the collection box 6 reaches the sampling depth, the drive mechanism drives the drive gear 17 to rotate. Through the transmission of the drive gear 17 and the gear ring 16, the rotating plate 15 rotates, aligning the through hole with a sampling hole 18. Water enters the sampling chamber through the through hole and the sampling hole 18 for sampling. After sampling, the rotating plate 15 continues to rotate, misaligning the through hole with the sampling hole 18 to close the sampling chamber. Then, the depth of the collection box 6 can be adjusted, and different sampling can be performed through the remaining sampling chambers. Sampling at depth; after sampling, the fixing bolt 8 can be rotated to remove it. At this time, the connecting block 9 is no longer connected to the fixing plate 3 through the fixing bolt 8, and the collection box 6 can be removed downwards. The side wall of the collection box 6 is separated from the slot 10. The sampling chamber is cleaned. After cleaning, the side wall of the collection box 6 is inserted into the slot 10. The sealing ring 11 seals the gap between the slot 10 and the collection box 6. The connecting block 9 is connected to the fixing plate 3, and then the fixing bolt 8 is screwed in. The bottom end of the fixing bolt 8 is connected to the connecting block 9 to fix the collection box 6.

[0028] The collection box 6 can be easily removed by the connecting components, making it convenient to clean the collection box 6.

[0029] With a rotating plate 15, a gear ring 16, a drive gear 17, and a sampling hole 18, the sampling chamber can be electrically connected to the outside after the sampling depth is reached, eliminating the need for manual connection and making operation convenient.

[0030] Example 2: Water sample collection device. This example is based on Example 1, with the following improvements: Figure 1 As shown, the lifting mechanism includes a connecting rod 12 and a rubber-coated steel wire rope 13. The connecting rod 12 is fixedly connected to the top outer wall of the fixed plate 3. One end of the rubber-coated steel wire rope 13 is fixedly connected to the top of the connecting rod 12. The top outer wall of the support frame 4 is provided with a winding and unwinding assembly 5 for controlling the length of the rubber-coated steel wire rope 13. The winding and unwinding assembly 5 is a mature existing technology, and its basic structure is well known to those skilled in the art, so it will not be described in detail here. The inner wall of the support frame 4 is fixedly connected to multiple telescopic cylinders 14, and the other end of the multiple telescopic cylinders 14 is fixedly connected to the fixed plate 3.

[0031] When adjusting the depth of the collection box 6, the winding and unwinding assembly 5 releases the rubber-coated steel wire rope 13, and the collection box 6 descends under gravity. The multi-section telescopic cylinder 14 extends accordingly, and the multi-section telescopic cylinder 14 limits the collection box 6 to prevent it from swaying in the water.

[0032] With the lifting mechanism in place, the collection box 6 can be provided with all-round support, effectively resisting the impact of water flow and maintaining a stable vertical descent.

[0033] Working principle: During sampling, the device is placed on the water surface. The winding assembly 5 releases the rubber-coated steel wire rope 13, causing the collection box 6 to descend under gravity. The multi-section telescopic cylinder 14 extends accordingly, limiting the collection box 6 and preventing it from swaying in the water. When the collection box 6 reaches the sampling depth, the drive mechanism drives the drive gear 17 to rotate. Through the transmission of the drive gear 17 and the gear ring 16, the rotating plate 15 rotates, aligning the through hole with a sampling hole 18. Water enters the sampling chamber through the through hole and the sampling hole 18 for sampling. After sampling, the rotating plate 15 continues to rotate, misaligning the through hole with the sampling hole 18, thus aligning the sampling chamber... The chamber is sealed, and the depth of the collection box 6 can be adjusted to sample at different depths through the other sampling chambers. After sampling, the fixing bolt 8 can be rotated to remove it. At this time, the connecting block 9 is no longer connected to the fixing plate 3 through the fixing bolt 8, and the collection box 6 can be removed downwards. The side wall of the collection box 6 is separated from the slot 10 to clean the sampling chamber. After cleaning, the side wall of the collection box 6 is inserted into the slot 10, and the sealing ring 11 seals the gap between the slot 10 and the collection box 6. The connecting block 9 is connected to the fixing plate 3, and then the fixing bolt 8 is screwed in. The bottom end of the fixing bolt 8 is connected to the connecting block 9 to fix the collection box 6.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
