Traditional coal sampling methods are mostly designed for coal piles or stationary coal, which are not suitable for dynamic coal flow in pipeline transportation. Currently, there are some shortcomings in the sampling devices for coal transportation pipelines.

[0003] Traditional coal transportation pipeline sampling devices often have complex structural designs and cumbersome installation and disassembly processes. When performing sampling operations, staff need to spend a lot of time and energy, which not only reduces work efficiency but also increases labor intensity. Some devices require specialized tools to disassemble in multiple steps to complete sampling. For work scenarios with frequent sampling, this operation method seriously affects the work progress. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figures 1-5. This utility model provides a technical solution:

[0018] Example 1: A coal slurry sampling device based on a coal transportation pipeline, comprising a movable pipe 1, a connecting pipe 2 fixedly connected to the upper end of the movable pipe 1, and a cover plate 3 fastened to the upper end of the connecting pipe 2.

[0019] In use, the moving pipe 1 can be used in conjunction with external equipment to move and transport the dynamic coal flow. When sampling is required, the cover plate 3 can be opened and the sample can be taken through the connecting pipe 2.

[0020] Example 2: The technical solution of this example, which differs from Example 1, includes: Installation openings 4 are provided on both sides of the cover plate 3; sliding grooves 5 are provided on the inner walls of both sides of the installation openings 4; connecting grooves 6 are provided on the upper ends of both sides of the connecting pipe 2; slots 7 are provided on the inner walls of the opposite sides of the connecting grooves 6; installation plates 8 are fixedly connected to the inner walls of the installation openings 4 away from the slots 7; telescopic dampers 9 with externally wrapped springs are fixedly connected to both sides of the installation plates 8; vertical plates 10 are fixedly connected to the other side of the telescopic dampers 9; locking blocks 11 are fixed to the side of the vertical plates 10 near the slots 7, and the locking blocks 11 are engaged inside the slots 7; pull rods 13 are fixedly connected to the upper ends of the vertical plates 10; sliding rods 1 are fixedly connected to both sides of the pull rods 13. 2. The slide rod 12 is slidably connected to the inside of the slide groove 5 on both sides. The lower end of the cover plate 3 extends into the moving tube 1 through the connecting pipe 2 via a cable, and the lower end of the cable is fixedly connected to the sampler 18. Stepper motors 14 are fixedly connected to both sides of the middle part of the cover plate 3. The output end of the stepper motor 14 is fixedly connected to the winding wheel 15 via a rotating rod. The winding wheel 15 is connected to the connecting rope 16 via a drive. The other side of the connecting rope 16 is fixedly connected to the pull rod 13. The upper outer walls of both sides of the moving tube 1 are fixedly connected to the symmetrically arranged electric telescopic rods 17. The output ends of the electric telescopic rods 17 are fixedly connected to the outer walls of both sides of the cover plate 3 via brackets. The stepper motor 14 drives the winding wheel 15 to move in the opposite direction via the rotating rod.

[0021] When sampling is required by opening cover 3, the stepper motor 14 on cover 3 is started by connecting an external power source. The output of stepper motor 14 drives the winding wheel 15 to rotate via a rotating rod. The rotation of winding wheel 15 will wind up the connecting rope 16. As the connecting rope 16 winds up, it will gradually pull the pull rod 13. The pull rod 13, under the force, will move stably in conjunction with the sliding rod 12 under the sliding limit action inside the sliding groove 5. As the pull rod 13 moves, it will synchronously drive the lower vertical plate 10 to move. The vertical plate 10 will drive the locking block inside the locking groove 7. 11 moves out of the slot 7. At the same time, as the vertical plate 10 moves, it will continuously compress the spring and the telescopic damper 9. The external limiter limits the rotating rod and the winding wheel 15. At this time, the cover plate 3 will release the limit from the connecting pipe 2. The electric telescopic rods 17 on both sides of the moving pipe 1 will be activated. The output end of the electric telescopic rod 17 will push the cover plate 3 to rise through the bracket. When the cover plate 3 rises, it will drive the sampler 18 to rise through the cable, thereby taking liquid coal samples from the moving pipe 1. Finally, it will be taken out from the inside of the connecting pipe 2 for testing.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
