Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a detachable pipeline sound-absorbing covering device. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

This system includes a lower semi-circular arc-shaped pipe support, an upper semi-circular arc-shaped pipe support, and a lifting assembly installed below the pipe for raising and lowering the lower semi-circular arc-shaped pipe support. The lower and upper semi-circular arc-shaped pipe supports interlock to form a circular pipe support that tightly hugs the pipe. Sound-insulating cotton is added to the inner circumferential walls of both the lower and upper semi-circular arc-shaped pipe supports. The lifting assembly includes a horizontally fixed plate on the ground, driving components at both ends of the fixed plate, and a lifting plate connected to the driving components. The lifting plate rises and falls vertically under the drive of the driving components, and the lifting plate is detachably connected to the lower semi-circular arc-shaped pipe support. The advantage of this utility model is that it is suitable for noise reduction treatment of pipes at various ground heights.

[0004] The existing equipment has the following problems when in use: the pipelines are numerous, the workload of a series of protection and sound insulation treatments for the pipelines is huge, and due to the different environments in which the pipelines are located, it is difficult to install the protective devices, and subsequent maintenance is also inconvenient. Especially when facing complex pipeline layouts, the disassembly and reinstallation process is time-consuming and labor-intensive, which exacerbates the complexity and economic burden of maintenance.

The insulation layer increases the insulation effect of the pipeline and reduces the temperature loss of the pipeline. The sound insulation layer prevents the leakage of internal noise from the pipeline, effectively reducing the noise pollution generated during pipeline operation. Secondly, the integrated design of the sound insulation layer and the extension makes the subsequent installation and disassembly of the sound insulation layer extremely simple, greatly improving work efficiency and facilitating subsequent maintenance and replacement.

[0012] Preferably, the groove has a fixing hole inside, which is adapted to a fixing bolt.

[0013] By adopting the above technical solution, the connection stability of the upper and lower connecting parts can be enhanced by inserting the fixing bolt into the fixing hole.

[0014] Preferably, a sealing gasket is provided between the upper connecting part and the lower connecting part.

The sound insulation layer 9 prevents the leakage of noise inside the pipeline and effectively reduces the noise pollution generated during pipeline operation. Furthermore, the integral molding design of the sound insulation layer 9 and the extension part 7 makes the subsequent installation and disassembly of the sound insulation layer 9 extremely convenient, greatly improving work efficiency and facilitating subsequent maintenance and replacement.

[0026] Working principle: The insulation layer 8 is bonded to the sound insulation layer 9. The extension 7 on the sound insulation layer 9 is inserted into the slot, thereby installing the sound insulation layer 9 inside the upper connecting part 4 and the lower connecting part 10. The insulation layer 8 increases the insulation effect of the pipeline and reduces the temperature loss of the pipeline. The sound insulation layer 9 prevents the leakage of internal noise from the pipeline and effectively reduces the noise pollution generated during pipeline operation. Secondly, the sound insulation layer 9 and the extension 7 are integrally molded, which makes the subsequent installation and disassembly of the sound insulation layer 9 extremely simple, greatly improving work efficiency and facilitating subsequent maintenance and replacement. When the upper connecting part 4 and the lower connecting part 10 are aligned, the rotating fixing block 1 drives the roller 2 to slide in the slide groove 3. The fixing block 1 then enters the lower connecting part 10 to complete the pre-connection. At this time, the fixing bolt 5 is rotated to align with the fixing hole 6 to firmly connect the upper connecting part 4 and the lower connecting part 10. The sealing gasket can effectively prevent sound leakage from the connection. In subsequent use, if it is necessary to replace the sound insulation layer 9 or the insulation layer 8, simply loosen the fixing bolt 5 to separate the upper connecting part 4 and the lower connecting part 10.
