[0021] In this embodiment, the support frame 1 is fixed at the predetermined position according to the design requirements, ensuring that the levelness and perpendicularity of the support frame 1 meet the standards to ensure the stability and safety of the pipeline device 2 after installation. The stable installation of the support frame 1 is the basis for the normal operation of the entire pipeline device 2, which can effectively bear the weight and pressure of the pipeline and the internal water flow. The engineering pipeline body 21 is placed on the support frame 1 at the appropriate position for preliminary positioning. The engineering pipeline body 21 serves as the main channel for water flow transmission. The communication assembly 3 is installed at one end of the engineering pipeline body 21 and is used to realize the connection between different pipelines and the water flow through.

The second fixed seat 43 is detachably installed at the bottom of the first fixed seat 42. The first fixed seat 42 and the second fixed seat 43 are fixedly connected together through the bolts 44, ensuring firm and reliable connection. The sealing assembly 45 is clamped and arranged between the second fixed seat 43 and the communication pipe 41.

The first fixed seat 42 and the second fixed seat 43 in the installation device 4 are detachably connected through the bolts 44. This design makes it convenient to disassemble and install when maintenance or replacement of parts is needed, reducing maintenance cost and difficulty. The sealing assembly 45 adopts a multi-layer sealing design. The cross clamping ring sleeve 451 is clamped with the inner wall of the second fixed seat 43, and the fourth sealing ring 452 is installed on both sides, forming multiple sealing lines. The multi-layer sealing structure can effectively prevent water leakage. Even in the case of long-term use or under certain external force, it can also maintain good sealing performance. When the sealing performance of the sealing ring is reduced due to wear or temperature change, the compression spring 453 can produce elastic deformation and continuously press the sealing ring, compensating for the sealing gap, thereby ensuring the durability of the sealing effect. The double-layer clamping plate 423 of the first fixed seat 42 has several sets of counterweight blocks 424 installed inside, increasing the weight and stability of the first fixed seat 42. When the pipeline is impacted by water flow or external vibration,The counterweight 424 can play a buffering and stabilizing role, reduce the shaking and displacement of the pipeline, ensure the normal operation of the pipeline device 2, the double-layer clamping plate 423 is clamped and installed at the groove combined by the fixed seat sleeve 421 and the first flange seat 422, and the outer wall thereof is tightly installed with the outer wall of the communication pipe 41. This clamping and fixing mode can effectively fix the communication pipe 41, prevent it from loosening or falling off during operation, and improve the structural reliability of the whole pipeline device 2.

[0022] Specifically, the second fixing seat 43 comprises a second flange seat 431, a first clamping sleeve 432, a second sealing ring 433 and a third sealing ring 434. The first clamping sleeve 432 is arranged at the top end of the second flange seat 431, the second sealing ring 433 is arranged at the outer periphery of the first clamping sleeve 432 and the outer wall of the second flange seat 431, and the first clamping sleeve 432 is clamped and installed at the bottom wall of the second flange seat 431.

[0023] In this embodiment, the second fixed seat 43 is provided with a second sealing ring 433 and a third sealing ring 434, which together with the fourth sealing ring 452 in the previous sealing assembly 45 form a multi-layer sealing structure. The second sealing ring 433 is located between the outer wall of the second flange seat 431 and the first sleeve ring 432, which can effectively prevent external impurities and water vapor from entering the second fixed seat 43, and prevent internal water flow from leaking to the outside. The third sealing ring 434 plays a sealing role at the connection with the connecting pipe 41 and other components, further enhancing the sealing performance of the entire installation device 4. The multi-layer sealing design can block the water flow at different levels and positions, greatly reducing the risk of water leakage. The sealing rings work together to form a complete sealing system. The second sealing ring 433 and the third sealing ring 434 can undertake the main sealing task according to different pressures and working environments. In the case of low pressure, the third sealing ring 434 plays a major sealing role. When the pressure is high or subjected to external impact, the second sealing ring 433 can provide additional sealing protection to ensure the stability of the sealing effect. The first sleeve ring 432 is installed in the bottom wall of the second flange seat 431, which increases the structural strength of the second flange seat 431. When the pipeline is subjected to water flow impact or external vibration, the first sleeve ring 432 can provide certain support and fixation, reducing the deformation and shaking of the second flange seat 431, thereby improving the stability of the entire second fixed seat 43. The clamping connection between the first sleeve ring 432 and the second flange seat 431 makes the connection between them more firm and less likely to loosen. The second fixed seat 43 is detachably connected to the first fixed seat 42 through the bolts 44, which not only ensures the firmness of the connection, but also facilitates subsequent maintenance and repair. During installation, proper bolt tightening sequence and torque control can make the second fixed seat 43 tightly combined with the first fixed seat 42 to form a whole. During pipeline operation, the two can jointly bear the water flow pressure and external force, improving the structural reliability of the entire installation device 4.

[0024] Specifically, the inner wall of one end of the connecting pipe 41 is provided with a clamping groove 411, and the clamping groove 411 is clamped and installed with the first sleeve ring 432.

[0025] In this embodiment, the groove 411 on the inner wall of one end of the connecting pipe 41 is engaged with the first retaining ring 432, which makes the connection between the two highly accurate and stable. The shape and size of the groove 411 match the first retaining ring 432, which can form a tight mechanical connection. When the pipeline is subjected to water flow impact, vibration or external pressure, the engagement structure of the groove 411 and the first retaining ring 432 can effectively resist these external forces, prevent the connection from loosening or falling off, and ensure the overall structural stability of the pipeline device 2. The bolt 44 connection provides additional tension and constraint, which makes the second fixing seat 43 tightly connected with the first fixing seat 42, and also indirectly strengthens the connection between the connecting pipe 41 and the second fixing seat 43. In complex engineering environments, multiple fixing methods can ensure that the pipeline device 2 can operate stably under various working conditions.

[0026] Specifically, rubber sleeves 425 are fixedly installed at the snap-fit ​​joints of the fixed seat 421 and the first flange seat 422, and a first sealing ring 426 is provided on the inner wall of the other end of the first flange seat 422.

[0027] In this embodiment, a rubber sleeve 425 is installed at the snap-fit ​​joint between the fixed seat 421 and the first flange seat 422. The rubber sleeve 425 has good elasticity and flexibility. When the pipeline is subjected to water flow impact, vibration or external pressure, the rubber sleeve 425 can play a role in buffering and shock absorption, reducing stress concentration between the fixed seat 421 and the first flange seat 422, and preventing damage to the snap-fit ​​joint due to excessive force. The rubber sleeve 425 can also fill the small gaps at the snap-fit ​​joint, increase the tightness of the connection, and prevent the connection from loosening. The presence of the rubber sleeve 425 optimizes the snap-fit ​​structure between the fixed seat 421 and the first flange seat 422. It can make the snap-fit ​​smoother, reduce friction and wear during the snap-fit ​​process, and improve the quality and reliability of the snap-fit. During long-term use, the rubber sleeve 425 can maintain the stability of the snap-fit ​​joint, ensuring that the fixed seat 421 and the first flange seat 422 are always tightly connected.
