Description

Technical Field

[0001] This utility model relates to a pipeline for water conservancy engineering construction, and in particular to a pipeline for water conservancy engineering construction, belonging to the field of water conservancy engineering technology. Background Technology

[0002] Water conservancy engineering programs cultivate senior engineering and technical personnel with knowledge in surveying, planning, design, construction, scientific research, and management of water conservancy projects, enabling them to work in planning, design, construction, scientific research, and management in water conservancy, hydropower, and soil and water conservation departments.

[0003] Traditional pipeline systems typically employ rigid connections, resulting in poor structural flexibility. When uneven settlement occurs in the foundation, significant stress concentration can easily occur inside the pipeline, greatly increasing the risk of circumferential or longitudinal cracking. Similarly, when traversing areas with complex geological conditions and prone to deformation, such as earthquake zones and landslide areas, these pipelines face extremely high risks of damage, severely impacting their safety and durability.

[0004] Therefore, there is an urgent need to improve a type of pipeline used in water conservancy engineering construction in order to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a pipeline for water conservancy engineering construction, making the pipeline system a flexible network that can absorb deformation and displacement and prevent pipeline rupture.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a pipeline for water conservancy engineering construction, comprising a first pipeline and a second pipeline, wherein a first connecting ring is provided at one end of the first pipeline, a second connecting ring is provided at one end of the second pipeline, a plurality of ball grooves are provided on one side of the first connecting ring, at least two lip-shaped sealing rings are fixedly installed in the ball grooves, and a ball head is provided at one end of the second connecting ring, wherein the ball head is in rolling connection with the ball grooves.

[0007] Preferably, the first connecting ring and the second connecting ring are provided with clamps on their outer sides, and a ring-shaped sealing ring is fixedly installed on the inner side of the clamps.

[0008] Preferably, a ball socket is provided on one side of the second connecting ring, and the ball head is in rolling connection with the ball socket, the number of ball sockets being the same as the number of ball grooves.

[0009] Preferably, corrugated pipes are fixedly installed on both the first pipe and the second pipe, and the corrugated pipes are located on the side close to the first connecting ring and the second connecting ring.

[0010] Preferably, both the first connecting ring and the second connecting ring are provided with threaded holes, and the number of threaded holes is at least four, and the four threaded holes are symmetrically arranged.

[0011] Preferably, the threaded hole is threadedly connected to a bolt, and the bolt is threadedly connected to a wear-resistant bushing.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. When the second connecting ring contacts the surface of the first connecting ring, the ball head is inserted into the ball groove. This allows the two pipe sections to deflect freely within a certain angle. The lip seal has self-tightening properties; the higher the internal water pressure, the tighter the sealing lip grips, resulting in a better sealing effect. When the pipe is subjected to external force, the ball head will roll within the ball groove and socket, causing slight displacement of the pipe. This perfectly adapts to foundation settlement and external impacts, releasing stress through deflection and preventing pipe cracking. A clamp is installed between the two connecting rings, with a ring-shaped sealing ring fixed inside, further enhancing the overall sealing performance. The clamp is secured with bolts to ensure that the two connecting rings will not detach under internal pressure and external force. The multi-stage sealing ensures that the risk of leakage is extremely low even with deflection angles.

[0014] 2. The worker first places the wear-resistant bushing into the connecting ring, aligns the bolt with the threaded hole, and then tightens the bolt to make the bolt and the threaded hole engage, thus completing the installation of the wear-resistant bushing. The pipe and the wear-resistant bushing should be kept as smooth as possible, with no steps, to reduce turbulence and scouring, and greatly extend the service life of the pipe. If the wear-resistant bushing has a problem, only the wear-resistant bushing needs to be replaced, resulting in low maintenance costs. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Examples, such as Figures 1-5 As shown, a pipeline for water conservancy construction includes a first pipeline 1 and a second pipeline 2. A first connecting ring 4 is provided at one end of the first pipeline 1, and a second connecting ring 10 is provided at one end of the second pipeline 2. Several ball grooves 6 are formed on one side of the first connecting ring 4, and at least two lip seals 7 are fixedly installed within each ball groove 6. A ball head 9 is provided at one end of the second connecting ring 10, and the ball head 9 rolls into contact with the ball grooves 6. Clamps 3 are provided on the outer sides of the first connecting ring 4 and the second connecting ring 10, and ring seals 301 are fixedly installed on the inner side of the clamps 3. By providing at least two lip seals 7 within each ball groove 6, when the second connecting ring 10 contacts the surface of the first connecting ring 4, the ball head 9 engages within the ball groove 6, allowing the two... The pipe sections can freely deflect within a certain angle, and the lip seal 7 has self-tightening properties. The higher the internal water pressure, the tighter the sealing lip grips, and the better the sealing effect. When the pipe is subjected to external force, the ball head 9 will roll in the ball groove 6 and ball socket 8, and the pipe will undergo slight displacement, perfectly adapting to foundation settlement and external impact. Stress is released through deflection to prevent pipe cracking. At the same time, a clamp 3 is set between the two connecting rings, and a ring-shaped sealing ring 301 is fixedly installed inside the clamp 3, making the overall sealing performance better. The clamp 3 is fastened with bolts to ensure that the two connecting rings will not come apart when subjected to internal pressure and external force. The multi-stage sealing ensures that the risk of leakage is extremely low even when there is a deflection angle.

[0024] like Figures 2-4As shown, a ball socket 8 is further provided on one side of the second connecting ring 10, and the ball head 9 is rolled in connection with the ball socket 8. The number of ball sockets 8 is the same as the number of ball grooves 6. Corrugated pipes 5 are fixedly installed on both the first pipe 1 and the second pipe 2. The corrugated pipes 5 are located on the side close to the first connecting ring 4 and the second connecting ring 10. By setting the number of ball sockets 8 and ball grooves 6 to be the same, the ball head 9 rolling in the ball socket 8 can be connected to the ball groove 6. When the pipes are subjected to external force, the two pipes can be displaced. By installing the corrugated pipes 5 on the side close to the first connecting ring 4 and the second connecting ring 10, the pipe length change caused by thermal expansion and contraction is effectively absorbed, further reducing the system stress.

[0025] like Figures 2-4 As shown, furthermore, both the first connecting ring 4 and the second connecting ring 10 are provided with threaded holes 12, with at least four threaded holes 12. The four threaded holes 12 are symmetrically arranged. Bolts 11 are threadedly connected to the threaded holes 12, and wear-resistant bushings 13 are threadedly connected to the bolts 11. The operator first puts the wear-resistant bushing 13 into the connecting ring, aligns the bolts 11 with the threaded holes 12, and then tightens the bolts 11 so that the bolts 11 and the threaded holes 12 are threadedly connected, thereby completing the installation of the wear-resistant bushing 13. The pipe and the wear-resistant bushing 13 are kept as smooth as possible, with no steps, which reduces turbulence and scouring, and greatly extends the service life of the pipe. If the wear-resistant bushing 13 has a problem, only the wear-resistant bushing 13 needs to be replaced, resulting in low maintenance costs.

[0026] It is important to note that the pipe, corrugated pipe, and connecting ring are integrated into one unit without any seams, ensuring its airtightness and preventing leakage.

[0027] In this embodiment, as Figures 1-5 As shown in this embodiment, the principle of a pipeline for water conservancy engineering construction is as follows:

[0028] When the second connecting ring 10 contacts the surface of the first connecting ring 4, the ball head 9 is inserted into the ball groove 6. This allows the two pipe sections to deflect freely within a certain angle. The lip seal 7 has self-tightening properties. The higher the internal water pressure, the tighter the sealing lip grips, and the better the sealing effect. When the pipe is subjected to external force, the ball head 9 will roll in the ball groove 6 and the ball socket 8, and the pipe will undergo slight displacement, perfectly adapting to foundation settlement and external impact. Stress is released through deflection, preventing pipe cracking. At the same time, a clamp 3 is set between the two connecting rings, and a ring-shaped sealing ring 301 is fixedly installed inside the clamp 3, making the overall sealing performance better. The clamp 3 is fastened with bolts to ensure that the two connecting rings will not come apart when subjected to internal pressure and external force. The multi-stage sealing ensures that the risk of leakage is extremely low even when there is a deflection angle.
