Background Art

[0002] The present invention relates to the technical field of hydropower stations, and in particular to a hydropower station pressure pipeline upgrading and reconstruction system which combines air and water flow mixing technology and utilizes a vortex line inner tube structure design, and aims to improve the power generation efficiency of the hydropower station by increasing the pressure and flow velocity of the water flow and introducing air mixing. Summary of the invention

[0003] The utility model provides a hydropower station pressure pipeline renovation and upgrading system based on vortex effect, comprising a pressure water tank, a front pressure pipeline and a rear pressure pipeline, an inner pipe with vortex lines on the outer wall, an air introduction pipe, a flange connection joint, and a water turbine generator.

[0004] .Pressure water tank: stores and regulates water flow entering from upstream.

[0005] Pressure pipeline: It is divided into front pressure pipeline and rear pressure pipeline. The front pressure pipeline is embedded with an inner pipe with vortex lines on the outer wall, and the rear pressure pipeline is a hollow pipe. The two sections of pressure pipeline are connected by flange joints.

[0006] Inner tube with vortex line: The outer wall is designed in the shape of vortex line. The flowing water in the current pressure pipe flows along the outer wall of the inner tube with vortex line under the pressure of the pressure pool water, so that the water flowing through the pressure pipe forms a vortex and gushes out, thereby increasing the rotational force of the water flow and sucking the air at the top through the inner tube. The pressurized water flow in the front pressure pipe plus the air in the inner tube with vortex line on the outer wall enter the rear pressure pipe to form a high-pressure mixture of water and gas, achieving the effect of double pressurization.

[0008] Hydro-turbine generator: receives water flow accelerated by the vortex effect and mixed with air, and uses its kinetic energy to drive the generator to generate electricity.

[0009] Fixed flange connection joint: used to connect the front pressure pipe and the rear pressure pipe, and to fix the inner pipe with swirl line on the outer wall suspended in the pressure pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of the overall structure of an embodiment of the hydropower station pressure pipeline upgrading and transformation system. DETAILED DESCRIPTION

[0011] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings.

[0012] like Figure 1 As shown, the utility model is a hydropower station pressure pipeline renovation and upgrading system based on the vortex effect, which mainly includes an air duct 1, a pressure water tank 2, a front pressure pipeline 3, an inner pipe 4 with a vortex line on the outer wall, a flange connection joint 5, a rear pressure pipeline 6, and a turbine generator 7.

[0013] The air duct 1 is located above the pressure water tank 2 and is used to introduce external air. When the hydropower station is in operation, air enters the inner tube 4 with vortex lines on the outer wall through the air duct 1 and mixes with the vortex water of the rear pressure pipe 6 to form a water-gas mixture.

[0014] The pressure tank 2 is a facility used to store and regulate water flow in a hydropower station. Water flows into the pressure tank 2 from upstream, and enters the front pressure pipe 3 through a certain pressure effect. It then impacts the turbine generator through the rear pressure pipe 6 to generate electricity.

[0015] The front end of the front pressure pipe 3 is connected to the bottom of the pressure pool and is embedded in the inner pipe 4 with vortex lines on the outer wall. The flowing water in the current pressure pipe flows along the outer wall of the inner pipe with vortex lines under the pressure of the pressure pool water, causing the water flow in the pressure pipe to form a vortex and gush out, thereby increasing the rotational force of the water flow and sucking the air at the top through the inner pipe 4 with vortex lines on the outer wall, and entering the rear pressure pipe 6 to form a water-gas high-pressure mixture, achieving a double pressurization effect.

[0016] The inner tube 4 with vortex lines on the outer wall is connected to the air duct 1, and it is nested in the front pressure pipe 3. The outer wall of the inner tube 4 is designed to be in the shape of a vortex line, and a strong vortex effect is generated when the water flows through the outer wall. This vortex effect can enhance the rotational force and density of the water flow, thereby increasing the kinetic energy of the water flow. At the same time, the air enters the inner tube 4 with vortex lines through the air duct 1, and is sucked by the vortex water flow of the front pressure pipe 3 to mix with the water in the rear pressure pipe 6 to form a water-gas mixture. Under the action of the vortex effect, this water-gas mixture has higher energy density and flow rate.

[0017] The flange connection joint 5 is used to connect the front pressure pipeline and the rear pressure pipeline, and to fix the inner pipe with the swirl line on the outer wall suspended in the pressure pipeline.

[0018] The rear pressure pipe 6 is completely hollow, receiving the water flow that has passed through the front pressure pipe 3 and has fully rotated to form a vortex, and the air sucked into the inner pipe 4 with vortex lines on the outer wall, forming a high-strength and high-pressure water-gas mixture to impact the hydro-generator 7 to generate electricity.

[0019] The hydro-turbine generator 7 is a power generation device in a hydropower station. When the water-gas mixture hits the blades of the turbine, the blades rotate, thereby driving the generator to generate electricity. Since the water-gas mixture has a higher energy density and flow rate under the action of the vortex effect, the hydro-turbine generator 7 can generate more electricity. This practical technology not only makes full use of water resources, but also maximizes economic benefits.
