Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and flood prevention, and in particular to a drainage device for water conservancy construction. Background Art

[0002] Hydraulic engineering, a branch of civil engineering, deals with the flow and transport of fluids, primarily water and sewage. A hallmark of these systems is the extensive use of gravity as the force that causes fluid movement. This area of ​​civil engineering is closely related to the design of bridges, dams, channels, canals, and levees, as well as sanitary and environmental engineering. Hydraulic engineering applies the principles of fluid mechanics to problems related to the collection, storage, control, transportation, regulation, measurement, and use of water.

[0003] In order to handle the drainage of water, pipe discharge is usually adopted in the prior art. However, the water usually contains sediment, so most of the sediment will remain in the pipe during the drainage process, so the pipe needs to be dredged frequently. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a drainage device for water conservancy construction, which is used to solve the problem in the existing technology that most of the sediment will remain in the pipeline during the drainage process, resulting in the need to frequently dredge the pipeline.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solution: a drainage device for water conservancy construction, comprising an inlet pipe and an outlet pipe, a vertical acceleration pipe being connected between the outlet pipe and the inlet pipe, a streamline groove being opened inside the inlet pipe, and a flow velocity component for causing water to form a vortex being provided in the outlet pipe.

[0006] By adopting the above technical solution, when water enters the inlet pipe, it will be initially accelerated and form a vortex due to the streamline groove opened inside the inlet pipe, and then enter the vertical acceleration pipe for secondary acceleration. Then, as the water enters the vortex component in the outlet pipe, the water will vortex. The vortex will bring most of the sediment in the water into the vortex, thereby reducing the amount of sediment remaining in the pipe. By increasing the water flow rate and forming small vortices, the amount of sediment remaining in the pipe can be reduced.

[0007] Furthermore, the flow velocity component includes a vortex tube rotatably connected to the inside of the inlet pipe, and the inside of the vortex tube is provided with vortex grooves, and the vortex grooves are evenly distributed in the vortex tube.

[0008] By adopting the above technical solution, when water enters the vortex tube along the vertical acceleration pipe, the water that has been initially accelerated will drive the vortex tube to rotate along with the vortex groove, further increasing the water rotation speed and allowing the sediment to flow with the water.

[0009] Furthermore, the streamline groove extends into the acceleration pipe.

[0010] By adopting the above technical solution, it is ensured that water can be accelerated evenly.

[0011] Furthermore, both ends of the vortex pipe are provided with fixing rings, and a matching fixing groove is provided on the outlet pipe, and the fixing ring is rotatably connected in the fixing groove.

[0012] By adopting the above technical solution, the fixed ring is rotatably connected to the fixed groove in the outlet pipe, so that the water in the vortex groove drives the vortex pipe to rotate.

[0013] Furthermore, a trumpet-shaped guide tube is provided at one end of the vortex tube facing the acceleration tube.

[0014] By adopting the above technical solution, the provision of the guide pipe ensures that water can normally enter the outlet pipe.

[0015] Furthermore, the wide side of the guide tube fits in the accelerating tube.

[0016] By adopting the above technical solution, the fluidity of water in the accelerated pipeline flowing into the guide pipe is ensured.

[0017] Furthermore, the guide tube is fixedly provided with a rotating ring, and the rotating ring is rotatably connected in the outlet pipe.

[0018] By adopting the above technical solution, the guide tube is rotatably connected to the outlet pipe, thereby ensuring the integrity of the guide tube and the vortex tube.

[0019] Furthermore, the water inlet pipe, outlet pipe and acceleration pipe are made of polyethylene.

[0020] By adopting the above technical solution, the PE pipe has good flexibility and strong impact resistance and can be used in complex environments.

[0021] In summary, the present application includes the following beneficial technical effects: by integrating streamline grooves, acceleration pipes and vortex components, significant beneficial effects are demonstrated. The device cleverly guides and preliminarily accelerates the flow of water through the streamline grooves inside the inlet pipe, while forming vortices, laying the foundation for subsequent water flow acceleration and vortex formation. Subsequently, the water flow enters the vertical acceleration pipe, where it undergoes secondary acceleration, further increasing the kinetic energy of the water flow. When the water flow finally enters the outlet pipe, the vortex component begins to work. The vortex grooves inside the vortex tube are evenly distributed. When the water flow passes through these vortex grooves, it drives the vortex tube to rotate, thereby further increasing the rotation speed of the water. This design not only significantly increases the water flow speed, but more importantly, through the small vortices formed, most of the sediment in the water is effectively brought into the vortex, reducing the deposition of sediment in the pipe.

[0026] The present application is further described in detail below with reference to the accompanying drawings.

[0027] Example, see Figure 1 、 Figure 2 A drainage device for water conservancy construction includes an inlet pipe 1, an outlet pipe 2, and a vertical acceleration pipe 3 connecting the two. Streamline grooves 11 are provided within the inlet pipe 1. These flow grooves 11 guide the water flow, initially accelerating it upon entering the device and gradually forming eddies during the acceleration process. This accelerated, eddy-like flow then enters the vertical acceleration pipe 3 for a secondary acceleration, further increasing its velocity.

[0028] After successfully passing through the acceleration pipe 3, the water flows into the outlet pipe 2, where a velocity assembly is installed to further enhance the vortex effect of the water flow. This velocity assembly includes a vortex tube 21 that is rotatably connected to the interior of the inlet pipe 1. The interior of the vortex tube 21 is evenly distributed with vortex grooves 211. When the water flows through these vortex grooves 211, its kinetic energy drives the vortex tube 21 to rotate. This rotation further increases the speed of the water flow, causing the water flow to form a more intense vortex.

[0029] In this process, the formation of eddies plays a crucial role. It not only enhances the flushing ability of the water flow, but also effectively draws most of the sediment in the water into the eddies and carries them out of the pipe with the flow of water, thus significantly reducing the sediment deposition in the pipe.

[0030] In this embodiment, the streamline groove 11 extends into the acceleration pipe 3 to ensure that the water can be accelerated evenly.

[0031] In this embodiment, refer to Figure 3 Both ends of the vortex tube 21 are fixed with rings 23, and a matching fixed groove 24 is provided on the outlet pipe 2, and the fixed ring 23 is rotatably connected in the fixed groove 24. The fixed ring 23 is rotatably connected to the fixed groove 24 in the outlet pipe 2, so that the water rotates along with the vortex groove 211 and drives the vortex tube 21 to rotate.

[0032] In this embodiment, a trumpet-shaped guide pipe 22 is provided at one end of the vortex tube 21 facing the acceleration pipe 3. The provision of the guide pipe 22 ensures that water can enter the outlet pipe 2 normally.

[0033] In this embodiment, the wide side of the guide tube 22 fits in the accelerating pipe 3 to ensure the fluidity of the water in the accelerating pipe 3 flowing into the guide tube 22 .

[0034] In this embodiment, the guide tube 22 is fixedly provided with a rotating ring, which is rotatably connected to the outlet pipe 2. By rotatably connecting the guide tube 22 to the outlet pipe 2, the integrity of the guide tube 22 and the vortex tube 21 is ensured.

[0035] In this embodiment, the water inlet pipe, the outlet pipe 2 and the acceleration pipe 3 are made of polyethylene. PE pipes have good flexibility and strong impact resistance and can be used in complex environments.

[0036] Specific implementation process: Effectively reduce the deposition of sediment in the pipeline by increasing the water flow speed and forming vortexes. The device includes an inlet pipe 1 and an outlet pipe 2, which are connected by a vertically arranged acceleration pipe 3. A streamline trough 11 is designed inside the inlet pipe 1 to guide the water flow and initially accelerate it; a vortex assembly is provided inside the outlet pipe 2, including a vortex tube 21 that is rotatably connected to the inside of the inlet pipe 1, and vortex troughs 211 are evenly distributed inside the vortex tube 21. When the water flows through the inlet pipe 1, the streamline trough 11 guides the water flow to initially accelerate and form a vortex, and then enters the acceleration pipe 3 for secondary acceleration, and then enters the outlet pipe 2 to further form a vortex through the vortex assembly. The vortex tube 21 rotates with the water flow, further increasing the rotation speed of the water, and the vortex brings most of the sediment in the water into the vortex, reducing the deposition of sediment in the pipeline. The streamline trough 11 extends into the acceleration pipe 3 to ensure uniform acceleration of the water flow. There are fixing rings 23 at both ends of the vortex tube 21, which are rotatably connected in the fixing groove 24 of the outlet pipe 2 to ensure that the vortex tube 21 rotates with the water flow. A trumpet-shaped guide tube 22 is provided at one end of the vortex tube 21 facing the acceleration pipe 3 to ensure that the water flows smoothly into the vortex tube 21. The wide surface of the guide tube 22 fits the acceleration pipe 3 to ensure fluidity. The guide tube 22 is fixed with a rotating ring and rotatably connected in the outlet pipe 2 to ensure the integrity of the guide tube 22 and the vortex tube 21. The water inlet pipe, outlet pipe 2 and acceleration pipe 3 are made of polyethylene, which has good flexibility and impact resistance and can adapt to complex environments. During use, attention should be paid to installation and commissioning, maintenance and cleaning, and safe operation to ensure the normal operation of the device and extend its service life.
