Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower pipeline desilting, and more specifically, to a water conservancy and hydropower pipeline desilting device. Background Art

[0002] In the context of existing technologies, pipeline maintenance in the field of water conservancy and hydropower, especially dredging operations, faces a significant challenge. This challenge stems from the fact that the required fixed thrust for pipelines under different conditions to achieve a stable state and smoothly carry out internal dredging operations is variable. The effectiveness of the dredging process depends to a large extent on whether the mobile frame can provide appropriate thrust to ensure the stability of the pipeline during dredging according to the specific conditions of the pipeline, such as the diameter and material of the pipeline, and the nature of the internal sediment. Stable fixation is a prerequisite for the smooth progress of dredging operations, because only after the pipeline is stably fixed can the dredging equipment efficiently remove the sediment in the pipeline, ensure smooth water flow, and avoid potential blockage problems.

[0003] However, the existing dredging equipment lacks sufficient flexibility in design and cannot adjust the thrust according to the actual needs of the dredging operation. This design deficiency leads to a major limitation in actual operations, and it is impossible to provide a customized solution for pipelines of different specifications and conditions. For pipelines with larger diameters or harder internal sediments, a greater thrust is required to ensure that the dredging equipment can be stably attached to the inner wall of the pipeline; while for pipelines with smaller diameters or softer sediments, a smaller thrust is required to avoid damage to the pipeline. This limitation of the existing equipment not only affects the dredging efficiency, but may also increase the risk of pipeline damage, further affecting the safe operation and maintenance costs of the water conservancy and hydropower systems.

[0030] In this embodiment, since multiple mobile frames 3 need to be placed in the pipeline when silt removal is required, and at this time the diameter of the multiple mobile frames 3 is larger than the diameter of the pipeline, when a larger thrust is required, the fixing sleeve 6 with more fixing grooves 12 is selected and installed on the fixing plate 7, so that multiple fixing plates 7 can be fixed, and the spring 5 in the fixed position is in a fixed state, so the stiffness coefficient of the spring 5 becomes larger, and the thrust generated when the same distance is compressed is greater, thereby ensuring the fixation of the thrust, and when the two fixing sleeves 6 need to be fixed to each other, it is only necessary to clamp the threaded groove 15 on the insertion rod 11 on the one-way piece 13. Since the one-way piece 13 is arranged along the threaded groove 15, it will be effectively clamped, and when it needs to be unlocked, it is only necessary to push the unlocking sleeve 16 to contact the one-way piece 13, thereby unlocking the clamping between the one-way piece 13 and the insertion rod 11.

[0033] In summary, when the overall equipment is in use or running: since multiple mobile frames 3 need to be placed in the pipeline when dredging is required, and at this time the diameter of the multiple mobile frames 3 is larger than the diameter of the pipeline, when a larger thrust is required, the fixing sleeve 6 with more fixing grooves 12 is selected and installed on the fixing plate 7, so that multiple fixing plates 7 can be fixed, and the spring 5 in the fixed position is in a fixed state, so the stiffness coefficient of the spring 5 becomes larger, and the thrust generated when compressed by the same distance is greater, thereby ensuring the fixation of the thrust, and when the two fixing sleeves 6 need to be fixed to each other, it is only necessary to clamp the threaded groove 15 on the insertion rod 11 on the one-way piece 13. Since the one-way piece 13 is arranged along the threaded groove 15, it will be effectively clamped, and when it needs to be unlocked, it is only necessary to push the unlocking sleeve 16 to contact the one-way piece 13, thereby unlocking the clamping between the one-way piece 13 and the insertion rod 11.
