[0025] The water inlet component 7 includes a water inlet pipe 701, a spring 702 and a pad 703. The water inlet pipe 701 passes through the sampling tank 4, and a boss is provided in the water inlet pipe 701. The pad 703 is attached to the boss in the water inlet pipe 701. The back of the pad 703 is provided with a spring 702. The elastic force of the spring 702 is the same as the water pressure of the corresponding water depth.

[0026] In the utility model, a spring 702 and a pad 703 are provided. The spring 702 can support the pad 703. The pad 703 is fitted with the boss in the water inlet pipe 701 to close the water inlet pipe 701. When the sampling tank 4 sinks to the corresponding depth, the water pressure will exceed the elastic force of the spring 702, squeezing the spring 702 and the pad 703 apart, so that the water enters the water storage chamber 8, achieving the effect of stratified sampling, and the structure for achieving the purpose is very simple.

[0027] The water inlet pipe 701 is detachably connected to the sampling tank 4, and the spring 702 with different elastic forces can be replaced by disassembling the water inlet pipe 701;

[0028] By providing the water inlet pipe 701, the water inlet pipe 701 is detachably connected to the sampling tank 4, so that the springs 702 with different elastic forces can be quickly replaced to achieve stratified sampling work at different water depths.

[0029] A filter cartridge 704 is provided on the side of the water inlet pipe 701, and the filter cartridge 704 is used to filter the water entering the water inlet pipe 701;

[0030] By setting the filter cartridge 704, the filter cartridge 704 can cover the water inlet pipe 701, so that the water entering the water inlet pipe 701 can be filtered, thereby preventing impurities in the water from affecting the sampling results.

[0031] The exhaust component 5 includes an exhaust pipe 501 and a float 503. An active cavity 502 is provided in the exhaust pipe 501. The float 503 is located in the active cavity 502. The size of the float 503 is larger than the inner diameter of the exhaust pipe 501 and smaller than the inner diameter of the active cavity 502.

[0032] By setting the float 503 and the movable chamber 502, when the gas is discharged, the gas will push the float 503 open and be discharged to the outside. When the gas is completely discharged, the water flow will lift the float 503, causing the float 503 to float and block the top of the movable chamber 502, so that it closes the exhaust pipe 501, achieving the effect of exhausting air without draining water.

[0033] A threaded sleeve 10 is provided under the sampling tank 4, and a threaded member 9 is provided at a position corresponding to the threaded sleeve 10 on the sampling tank 4. The threaded sleeve 10 and the threaded member 9 are used to connect multiple groups of sampling tanks 4;

[0035] A magnetic member 6 is provided at the top of the sampling tank 4, and the magnetic member 6 is used to adsorb and fix the device. A sealing sleeve is provided on the outside of the magnetic member 6, and the sealing sleeve is used to prevent the water from corroding the magnetic member 6;

[0036] By setting up the magnetic component 6 and the sealing sleeve, the magnetic component 6 can be quickly connected to the external magnetic adsorption equipment, and can be used for remote delivery and collection by drones or unmanned ships, while the sealing sleeve can protect the magnetic component 6 to prevent the water flow from affecting the magnetic component 6.

[0037] Working principle:

[0038] When sampling, the equipment is put into water, and the submersible pump 2 injects water into the ballast tank 1, causing the equipment to sink and drive the sampling tank 4 to sink. When the sampling tank 4 sinks to the corresponding depth, the water pressure is higher than the pressure of the spring 702, which squeezes the pad 703 open, allowing the water to enter the water storage chamber 8. At the same time, the water in the water storage chamber 8 is discharged through the exhaust pipe 501. After the sampling is completed, the submersible pump 2 discharges the water in the ballast tank 1, allowing the equipment to float to the surface, completing the stratified sampling of the water body.

[0039] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
