Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and in particular to a pipeline with a siphon interruption structure for water conservancy engineering. Background Technology

[0002] The siphon effect, also known as the siphon phenomenon, is a physical phenomenon that refers to the phenomenon where liquid flows from the side with higher pressure to the side with lower pressure due to the attraction between liquid molecules and the difference in potential energy. Although the atmospheric pressure is the same on both sides of the water, the side with higher water pressure flows down due to gravity, while the side with lower water pressure flows up due to atmospheric pressure, until the atmospheric pressure plus the water pressure on both sides are equal, the water level in the container becomes the same height, and the water stops flowing.

[0003] However, existing water conservancy projects use pipelines equipped with siphon interruption structures, but the pipelines lack internal anti-siphon structures, so they cannot stop the siphon effect in time. When the pipelines are connected and installed, they are installed by bolts, but the bolt installation cannot increase the contact area, which will reduce the firmness and stability after installation. Utility Model Content

[0004] In view of the above problems, this application provides a pipeline with a siphon interruption structure for water conservancy projects, to solve the problems of existing pipelines with siphon interruption structures for water conservancy projects, which lack an internal structure to prevent siphoning, and cannot stop the siphoning effect in time when it occurs. In addition, when the pipeline is connected and installed, it is installed by bolts, which cannot increase the contact area and will reduce the firmness and stability after installation.

[0005] This application provides a pipeline with a siphon flow interruption structure for hydraulic engineering. It includes a pipe with symmetrically formed limiting grooves on its inner wall. A movable block is movably fitted inside the limiting groove. A first toothed groove is formed at the top of the movable block, and a second toothed groove is meshed with the surface of the first toothed groove. The second toothed groove is formed on the outer wall of a connecting block. The connecting block is hingedly installed inside the limiting groove. Four fan-shaped blades are fixedly installed at the top of the connecting block, and these four fan-shaped blades are disposed on the inner wall of the pipe.

[0006] With the above method, the two pipes are connected and installed. The four fan-shaped blades are pushed to one side by the flowing water. The push of the fan-shaped blades will also drive the connecting block. Since the connecting block is hinged inside the limiting groove, the fan-shaped blades will rotate around the hinge point. The second tooth groove will push the first tooth groove, and then drive the movable block to slide in the limiting groove. The water flow will push open the four fan-shaped blades. When the water flow causes a siphon backflow, the water flow will push the four fan-shaped blades to move in the opposite direction. The reverse movement of the fan-shaped blades will also drive the movable block to move. However, the other side of the movable block is attached to the inner wall of the limiting groove, so it cannot move and thus hinders the reverse rotation of the fan-shaped blades.

[0007] In some embodiments, a slot is provided on one side of the movable block, a connecting rod is movably sleeved on the inner wall of the slot, a telescopic spring is fixedly installed on one side of the slot, the telescopic spring is sleeved on the outer wall of the connecting rod, and the other side of the telescopic spring is fixedly installed on the inner wall of the limiting groove.

[0008] With the above scheme, when the four fan-shaped blades are pushed to one side by the flowing water, the movable block will slide on the outer wall of the connecting rod. The movement of the movable block will also cause the telescopic spring to extend and retract. After the water flow stops pushing, the telescopic spring can be used to reset the four fan-shaped blades.

[0009] In some embodiments, an installation ring is fixedly installed on one side of the pipe, a screw is movably sleeved on the outer wall of the installation ring, an installation block is threadedly connected to one side of the screw, and a connecting ring is fixedly installed on the other side of the pipe, with a plurality of installation grooves formed on the outer wall of the connecting ring.

[0010] The above method involves connecting two pipes together, allowing the connecting ring to be inserted into the connection between the mounting ring and the pipe. By tightening the screw, the mounting block moves along the outer wall of the screw, pushing it outward from the groove and into the mounting slot. This fixes the connecting ring at the connection between the mounting ring and the pipe. Tightening increases the contact area and the stress area, thus improving the firmness and stability of the installation.

[0011] In some embodiments, the mounting block is movably fitted inside the groove, the groove is symmetrically opened on the inner wall of the mounting ring, a slider is symmetrically movably fitted inside the groove, a movable strip is hinged to the top of the slider, and the top of the movable strip is hinged to the bottom of the mounting block.

[0012] With the above scheme, when the mounting block is pushed outward from the groove, it will also cause the movable strips on both sides to move and extend. Then the movable strips will drive the slider to slide in the groove. The movable strips on both sides provide limiting support for the mounting block and provide stability for the movement of the mounting block.

[0013] In some embodiments, a first sealing ring is symmetrically installed on the outer wall of the connecting ring, the first sealing ring being located on the right side of the mounting groove, and a second sealing ring is provided on both the mounting ring and one side of the pipe, the second sealing ring being located on the right side of the mounting block.

[0014] With the above solution, after the two pipes are connected and installed, the connecting ring is moved and embedded into the connection between the installation ring and the pipe. The first sealing ring and the second sealing ring seal the connection both before and after installation, thus preventing leakage after installation.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The four fan-shaped blades are pushed to one side by the flowing water. The push of the fan-shaped blades also drives the connecting block. Since the connecting block is hinged inside the limiting groove, the fan-shaped blades will rotate around the hinge point. The second tooth groove will push the first tooth groove, and then drive the movable block to slide in the limiting groove. The water flow will push open the four fan-shaped blades. When the water flow causes a siphon backflow, the water flow will push the four fan-shaped blades to move in the opposite direction. The reverse movement of the fan-shaped blades will also drive the movable block to move. The other side of the movable block is attached to the inner wall of the limiting groove, so it cannot move. Therefore, it hinders the reverse rotation of the fan-shaped blades and effectively prevents siphon.

[0017] 2. By connecting two pipes together, the connecting ring is inserted into the connection between the mounting ring and the pipe. Tightening the screw causes the mounting block to move along the threaded surface of the screw. The mounting block is pushed outward from the groove and then inserted into the mounting slot, fixing the connecting ring at the connection between the mounting ring and the pipe. Tightening increases the contact area and the force-bearing area, thus improving the firmness and stability of the installation.

[0030] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0031] This application provides a pipeline with a siphon flow interruption structure for use in water conservancy projects. For example... Figures 1-4 As shown, the device includes a pipe 1, with symmetrically arranged limiting grooves 2 on the inner wall of the pipe 1. A movable block 3 is movably sleeved inside the limiting groove 2. A first toothed groove 4 is provided at the top of the movable block 3. A second toothed groove 5 is meshed on the surface of the first toothed groove 4. The second toothed groove 5 is provided on the outer wall of the connecting block 6. The connecting block 6 is hinged and installed inside the limiting groove 2. A fan-shaped blade 7 is fixedly installed at the top of the connecting block 6. Four fan-shaped blades 7 are arranged on the inner wall of the pipe 1.

[0032] Two pipes 1 are connected and installed. The four fan-shaped blades 7 are pushed to one side by the flowing water. The push of the fan-shaped blades 7 will also drive the connecting block 6. Since the connecting block 6 is hinged inside the limiting groove 2, the fan-shaped blades 7 will rotate around the hinge point. The second tooth groove 5 will push the first tooth groove 4, and then drive the movable block 3 to slide in the limiting groove 2. The water flow will push open the four fan-shaped blades 7. When the water flow causes a siphon backflow, the water flow will push the four fan-shaped blades 7 to move in the opposite direction. The reverse movement of the fan-shaped blades 7 will also drive the movable block 3 to move. However, the other side of the movable block 3 is attached to the inner wall of the limiting groove 2, so it cannot move and thus hinders the reverse rotation of the fan-shaped blades 7.

[0033] In the technical solution of this application embodiment, a slot 8 is provided on one side of the movable block 3, a connecting rod 9 is movably sleeved on the inner wall of the slot 8, a telescopic spring 10 is fixedly installed on one side of the slot 8, the telescopic spring 10 is sleeved on the outer wall of the connecting rod 9, and the other side of the telescopic spring 10 is fixedly installed on the inner wall of the limiting groove 2.

[0034] When the four fan-shaped blades 7 are pushed to one side by the flowing water, the movable block 3 will slide on the outer wall of the connecting rod 9. The movement of the movable block 3 will also cause the telescopic spring 10 to extend and retract. After the water flow stops, the telescopic spring 10 can be used to reset the four fan-shaped blades 7.

[0035] In the technical solution of this application embodiment, an installation ring 11 is fixedly installed on one side of the pipe 1, a screw 12 is movably sleeved on the outer wall of the installation ring 11, an installation block 13 is threadedly connected to one side of the screw 12, and a connecting ring 17 is fixedly installed on the other side of the pipe 1, with a plurality of installation grooves 18 opened on the outer wall of the connecting ring 17.

[0036] The two pipes 1 are connected and installed together, so that the connecting ring 17 is movably embedded into the connection between the mounting ring 11 and the pipe 1. Then, the screw 12 is turned, so that the mounting block 13 moves threadedly on the outer wall of the screw 12. The mounting block 13 is pushed outward from the groove 14 and then movably embedded into the mounting groove 18, so that the connecting ring 17 is fixed at the connection between the mounting ring 11 and the pipe 1. By turning, the contact area of ​​the installation is increased, the force-bearing area is increased, and the firmness and stability of the installation are improved.

[0037] In the technical solution of this application embodiment, the mounting block 13 is movably sleeved inside the groove 14, the groove 14 is symmetrically opened on the inner wall of the mounting ring 11, and the slider 15 is symmetrically movably sleeved inside the groove 14. The top of the slider 15 is hingedly mounted with a movable strip 16, and the top of the movable strip 16 is hingedly mounted on the bottom of the mounting block 13.

[0038] When the mounting block 13 is pushed outward from the groove 14, it will also cause the movable strips 16 on both sides to move and extend. Then the movable strips 16 will drive the slider 15 to slide in the groove 14. The movable strips 16 on both sides provide limiting support for the mounting block 13, providing stability for the movement of the mounting block 13.

[0039] In the technical solution of this application embodiment, a first sealing ring 19 is symmetrically installed on the outer wall of the connecting ring 17. The first sealing ring 19 is located on the right side of the mounting groove 18. A second sealing ring 20 is provided on one side of the mounting ring 11 and the pipe 1. The second sealing ring 20 is located on the right side of the mounting block 13.

[0040] After the two pipes 1 are connected and installed, the connecting ring 17 is inserted into the connection between the mounting ring 11 and the pipe 1. The first sealing ring 19 and the second sealing ring 20 seal the connection and installation point from both the front and back to prevent leakage after installation.
