Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy engineering testing equipment, specifically relating to a water conservancy engineering sediment content collection and testing mechanism. Background Technology

[0002] In water conservancy projects, accurate detection of sediment content in water bodies is crucial. It has important significance for the planning, design, operation and management of water conservancy projects, as well as ecological environment assessment. However, the existing methods for collecting and detecting sediment content have many shortcomings. In the sample collection stage, traditional collection devices are mostly unable to adapt to water environments with different depths and flow rates. Many devices can only perform sampling at a single depth or angle, and cannot obtain comprehensive samples from different water layers. This results in samples that lack representativeness, which in turn affects the accuracy of the test results. In terms of the testing process, traditional equipment often separates the collection and testing processes, requiring manual transfer of the collected samples to specialized testing equipment for testing. This increases the complexity of the operation process, reduces testing efficiency, and can easily lead to problems such as sample contamination during sample transfer, which seriously affects the reliability of the test results. Utility Model Content

[0023] The lifting assembly includes a hydraulic telescopic rod 6, a mounting block 7, a motor 8, and a lead screw 9. A groove 5 is provided on the front surface of the frame 4, and the inner wall of the groove 5 is fixedly connected to the hydraulic telescopic rod 6. The mounting block 7 is fixedly installed at the output end of the hydraulic telescopic rod 6. The motor 8 is fixedly installed on the upper surface of the mounting block 7. A guide rod 11 is fixedly connected to the lower surface of the mounting block 7. The inner wall of the displacement block 10 is movably connected to the guide rod 11. The side surface of the lead screw 9 is threadedly connected to the displacement block 10. The lifting assembly can adjust the position of the sampling cylinder 23 in the water body, facilitating sampling of water at different depths. The guide rod 11 ensures the stability of the displacement block 10 during lifting and lowering, preventing swaying. The traveling wheels 2 facilitate movement of the mechanism at different detection locations, and a locking mechanism is provided on the traveling wheels 2, improving the equipment's mobility.

[0024] The detection assembly includes a detection platform 29, a detection position 30 and a weighing position 34 set on the upper surface of the detection platform 29, and a weighing sensor 35 fixedly connected to the bottom inner wall of the weighing position 34. The angle adjustment mechanism includes an electric telescopic rod 17, a winding roller 15 and a traction rope 16. The weighing sensor 35 is used to detect the weight of the collection tube 23 after water sample collection and the collection tube 23 after drying.

[0025] The sampling assembly includes a displacement block 10, an extension block 18 movably connected to the inner wall of the displacement block 10, a mounting post 20 fixedly connected to the inner wall of the extension block 18 via a spring 19, and a collection cylinder 23 fixedly connected to the side surface of the mounting post 20 via bolts.

The lower surface of the device is rotatably connected to a shaft 13. A gear 14 is fixedly connected to the side surface of the shaft 13. The gear 14 meshes with a rack 27. The side surface of the shaft 13 is fixedly connected to a winding roller 15. One end of the traction rope 16 is fixedly connected to the winding roller 15. A limit ring 21 is fixedly connected to the side surface of the mounting column 20. A circular ring 25 is fixedly connected to the side surface of the limit ring 21. The circular ring 25 is fixedly connected to the traction rope 16. A pressure sensor 22 is provided on the side surface of the limit ring 21.

When the collection tube 23 is at the bottom of the water body, it will prevent it from falling further and ensure the safety of the lifting component.

[0026] When collecting water samples, simply control the solenoid valve 24 to open so that water enters the collection tube 23. During the entry process, activate the electric telescopic rod 17 to push out the extension block 18, causing the collection tube 23 to move in the water. During the displacement, the rack 27 moves and rotates the gear 14 it meshes with, which in turn causes the winding roller 15 to rotate and wind up the traction rope 16. The traction rope 16 pulls the limit ring 21, causing the mounting column 20 to rotate. At this time, the spring 19 tightens and the collection tube 23 stands upright during rotation. During the rotation, water from different depths can be collected sequentially. By combining water samples from various depths, the comprehensiveness of the samples is ensured, and the accuracy of the test is improved.

[0027] A magnetic strip 181 is fixedly connected to the side surface of the extension block 18, and an iron strip 201 is fixedly connected to the side surface of the mounting column 20. The magnetic strip 181 can be attracted to the iron strip 201, making the collection cylinder 23 more stable in a parallel state. A control display 28 is fixedly connected to the rear surface of the frame 4. The control display 28 is used to control the start and stop of each component, and to receive and analyze information transmitted back by the pressure sensor 22. It also allows operators to intuitively control the operation of the equipment and view the test data, realizing human-machine interaction. The test table 29 is fixedly connected to the frame 4. The assembly includes a heating tube 32 and a rotating fan 33. A frame 31 is fixedly connected to the lower surface of the detection stage 29. The heating tube 32 is fixedly connected to the frame 31. The rotating fan 33 is set on the upper surface of the frame 31. A solenoid valve 24 is installed inside the collection tube 23. The solenoid valve 24 is used to open and close the opening at the upper end of the collection tube 23. The heating tube 32 is used to raise the temperature to heat the collection tube 23 placed in the detection position 30 to dry the internal moisture. When the rotating fan 33 is started, it blows the hot air generated by the heating tube 32 onto the collection tube 23 to make the heating more complete and reduce the drying time.

[0028] The working principle of this utility model is as follows: When collecting water samples from a body of water, push the device to the collection point, and fix the collection cylinder 23 on the mounting column 20 with bolts. Then, start the motor 8 to rotate the lead screw 9, thereby moving the displacement block 10 to the bottom of the lead screw 9. Then, according to the sampling depth, start the hydraulic telescopic rod 6 to adjust the height of the collection cylinder 23. When collecting water samples, simply control the solenoid valve 24 to open so that water enters the collection cylinder 23. During the entry process, start the electric telescopic rod 17 to push out the extension block 18, so that the collection cylinder 23 is displaced in the water. During the displacement process, the rack 27 is displaced and the gear 14 meshing with it rotates, thereby causing the winding roller 15 to rotate and wind up the traction rope 16. The traction rope 16 pulls the limit ring 21 to rotate the mounting column 20. At this time, the spring 19 tightens and the collection cylinder 23 stands up during rotation. During the rotation, water samples from different depths can be collected sequentially, and water samples from each depth can be combined.

[0029] After the data collection is completed, close the solenoid valve 24, start the hydraulic telescopic rod 6 and the motor 8 to move the collection cylinder 23 upward. The staff removes the collection cylinder 23 and places it on the weighing position 34 for weight detection. Then, place it in the detection position 30. After opening the solenoid valve 24, start the heating tube 32 to heat the collection cylinder 23 to evaporate the moisture. At the same time, start the rotating fan 33 to blow the hot air generated by the heating tube 32 onto the collection cylinder 23. After the moisture evaporates, place the collection cylinder 23 on the weighing position 34 for weighing again.
