[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below in conjunction with the drawings.

[0027] Please refer to Figures 1-4 The utility model discloses a layered self-adaptive sampling device for reservoir silt, which comprises:

[0028] The outer shell 11;

[0029] The sampling assembly includes three first electric push rods 21, a fixed frame 22, a connecting frame 23, a second electric push rod 24, a connecting frame 25 and a sampling tube 26. The first electric push rods 21 are arranged inside the outer shell 11. The fixed frame 22 is fixed at the output end of the first electric push rod 21. The connecting frame 23 is fixed at one side of the fixed frame 22, and the fixed frame 22 and the connecting frame 23 are mutually penetrated. The second electric push rod 24 is fixed inside the connecting frame 23. The connecting frame 25 is fixed at the output end of the second electric push rod 24 and extends into the fixed frame 22. The connecting frame 25 is fixed inside the sampling tube 26, and the sampling tube 26 is placed inside the fixed frame 22.

[0030] The outer shell 11 is the main frame of the whole sampling device, which provides physical support for the internal components. The three first electric push rods 21 can be controlled to extend or shorten by an external controller, so as to realize the position movement of the fixed frame 22 in three-dimensional space, thereby accurately determining the sampling position of the sampling tube 26. When the second electric push rod 24 works, it can drive the connecting frame 25 to move outside the fixed frame 22, thereby driving the sampling tube 26 to move towards the sludge and completing the sampling action.

[0031] The upper surface of the outer shell 11 is fixed with a buoyancy bin 12. The top surface of the fixed frame 22 is fixedly connected with the output end of the first electric push rod 21, and the lower surface of the fixed frame 22 is fixedly connected with the next first electric push rod 21. There are three groups of first electric push rods 21 connected with the fixed frame 22, and the lower surface of the fixed frame 22 of the last group is fixed with a spiral drill bit 29. The outer surface of the sampling tube 26 is provided with a balance hole 261. The rear side of the sampling tube 26 is fixed with a rubber ring 27. The front end of the sampling tube 26 is fixed with an electromagnetic valve 28, and the rear end of the sampling tube 26 is fixed with a memory alloy cover.

[0032] The connecting frame 25 cooperates with the second electric push rod 24 and the sampling tube 26 to transmit power and ensure the accurate movement of the sampling tube 26 during sampling. The balance hole 261 maintains the internal and external pressure balance of the sampling tube 26 during sampling, preventing excessive pressure difference from affecting the sampling effect or damaging the sampling tube 26. The buoyancy bin 12 provides buoyancy, so that the whole sampling device can float on the water surface. When the sampling tube 26 moves towards the sludge under the action of the electric push rod, the electromagnetic valve 28 is opened, and the sludge sample enters the sampling tube 26, completing the collection of the sample.

[0033] Working principle:

[0034] When sampling, only need to put the outer shell 11 into the reservoir, under the connection of the buoyancy bin 12, the outer shell 11 will float on the water surface, then through the external controller controls the first electric push rod 21, three first electric push rod 21 elongation, will drive the position adjustment of the fixed frame 22 synchronously, the fixed frame 22 moves, synchronously determines the sampling position of the sampling tube 26, then through the external controller, start the second electric push rod 24, the second electric push rod 24 drives the connecting frame 25 to move outside the fixed frame 22, the connecting frame 25 synchronously drives the sampling tube 26 to move to the sludge, and then opens the electromagnetic valve 28, the electromagnetic valve 28 opens to make the sludge enter the inside of the sampling tube 26, and then closes the electromagnetic valve 28 after sampling is completed;

[0035] This step can effectively avoid the leakage of sludge samples, ensure the integrity of the samples from entering the sampling tube 26 to the subsequent processing process, and is crucial for the subsequent accurate sample analysis and research.

[0036] Please refer to Figures 1-4 The embodiment shown in the embodiment is based on the above, further comprising:

[0037] The support assembly comprises a fixed frame 31, a third electric push rod 32, a cross plate 33, the fixed frame 31 is fixed at the top center of the buoyancy bin 12, the third electric push rod 32 is fixed inside the fixed frame 31, the output end of the third electric push rod 32 is fixed with the cross plate 33, and the cross plate 33 is slidably placed inside the fixed frame 31;

[0038] The fixed frame 31 provides a stable mounting base for the third electric push rod 32, ensuring that the third electric push rod 32 can perform extension and contraction motion in a fixed position. When the third electric push rod 32 is started, it can drive the cross plate 33 to move up and down inside the fixed frame 31, while driving the four movable plates 34 to move correspondingly.

[0039] The cross plate 33 is rotatably penetrated by the movable plate 34, the lower end of the movable plate 34 is rotatably penetrated by the support rod 35, the outer surface of the outer shell 11 is fixed with the limiting frame 36 on four sides, and the support rod 35 is slidably penetrated inside the limiting frame 36;

[0040] When the cross plate 33 moves up and down, the movable plate 34 will rotate around the connection point with the cross plate 33, while driving the support rod 35 to adjust the angle. When the support rod 35 is inserted into the sludge under the limitation of the limiting frame 36, an anchoring point will be formed in the sludge, resisting the inclination and shaking of the sampling device due to gravity, water flow impact and other factors.

[0041] Working principle:

[0042] When the sampling device is placed, the third electric push rod 32 is started by an external controller, the third electric push rod 32 is elongated, the cross plate 33 is synchronously moved downwards, the movable plate 34 is synchronously pushed to move downwards, and under the limiting of the limiting frame 36, the supporting rod 35 is inserted into the sludge, so that the sampling device is prevented from tilting and the accuracy of sampling is affected.

[0043] In this step, the supporting rod 35 is inserted into the sludge, and the outer shell 11 is supported and fixed from four directions, so that the sampling device is effectively prevented from tilting due to its own gravity or other external force factors.
