Technical Field
[0001] The utility model relates to the technical field of pipeline protection, in particular to a pipeline protection device for a sluice pump station. Background Art
[0002] A sluice pump station is a low-head hydraulic structure built on a river channel that uses the gate of a sluice to control flow and adjust water levels. Closing the gate can block floods, tides or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industrial and domestic water use; opening the gate can discharge floods, waterlogging, abandoned water or wastewater, and can also supply water to downstream rivers or channels. Pipes are required for the transportation of water in a sluice pump station. Existing sluice pump station pipelines, especially those set in the water flow, are often impacted by debris in the water body. Over time, it is easy to cause wear, deformation, or even damage to the pipe body, which will not only reduce the service life of the pipeline and increase the workload of maintenance personnel, but also affect the normal use of the pipeline and the normal water delivery of the sluice pump station, posing certain hidden dangers.

By connecting the installation components and the sealing protection components to the pipeline, the pipeline can be sealed and waterproofed, and by using the buffer protection components arranged on the sealing protection components, the pipeline can be further sealed and buffered, thereby reducing the probability of damage to the pipeline caused by the impact of debris in the water body and protecting the normal use of the pipeline.

At this time, the piston 7 is in a state of completely blocking the pipe opening of the pressure relief water outlet pipe 6, and the water will not be discharged from the pressure relief water outlet pipe 6. When the water pressure inside the water pipeline 1 is abnormal and causes the water pressure to be greater than the normal range, the water pressure will apply an upward thrust to the piston 7 and then push the piston 7 to slide vertically. At this time, the spring 8 is gradually compressed and deformed to generate elastic force, and the piston 7 gradually releases the blockage of the pipe opening of the pressure relief water outlet pipe 6. At this time, the water will be discharged from the pressure relief water outlet pipe 6, achieving the purpose of automatic pressure relief. When the water pressure inside the water pipeline 1 returns to normal When the pressure relief pressure threshold needs to be adjusted, the locking nut 16 is first loosened upwards, that is, the locking fixation of the screw rod 11 is released, and the screw rod 11 is driven to rotate by rotating the adjusting knob 12 clockwise, so that the connecting plate 9 can be driven to move vertically upwards through the shaft seat 10. At this time, the elongation of the spring 8 gradually increases, and the pressure relief pressure threshold gradually increases. Reduce. Similarly, by rotating the adjusting handle 12 counterclockwise to drive the screw rod 11 to rotate, the connecting plate 9 can be driven to move vertically downward through the shaft seat 10. At this time, the elongation of the spring 8 gradually decreases, and the pressure relief pressure threshold gradually increases. After the deformation of the spring 8 is adjusted appropriately, the locking nut 16 is tightened downward to lock and fix the screw rod 11, thereby facilitating the adjustment of the height position of the connecting plate 9, thereby changing the deformation of the spring 8, and adjusting the pressure relief pressure threshold of the water in the water pipeline 1, which can be suitable for pressure relief of water pipelines 1 of different models and materials.
