Description

Technical Field

[0001] This utility model belongs to the field of hydropower generation, and specifically relates to a lever-effect V-blade semi-circular horizontal water turbine nozzle structure. Background Technology

[0002] Currently, the more traditional power generation methods in society usually include thermal power generation, hydropower generation, wind power generation, photovoltaic power generation, nuclear power, etc. Among them, hydropower generation is widely used due to its advantages such as low cost, large power generation, and no environmental pollution.

[0003] The water turbine is the core equipment in hydroelectric power generation. Traditional water turbines typically include reaction turbines and impulse turbines. Reaction turbines include several types such as mixed-flow, axial-flow, oblique-flow, and through-flow turbines, while impulse turbines include several types such as bucket turbines, oblique-impact turbines, and double-impact turbines. Both impulse and reaction turbines generate electricity by jetting water, using the energy of the water flow to drive the turbine runner and ultimately the generator.

[0004] Reaction turbines and impulse turbines can be classified as horizontal or vertical depending on the main shaft configuration. However, existing horizontal turbines often have improperly positioned nozzles and spray angles, resulting in low water energy utilization and consequently affecting the turbine's power generation efficiency. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a lever-effect V-blade semi-circular horizontal water turbine nozzle structure that can maximize the utilization of water flow energy and improve power generation efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a lever-effect V-blade semi-circular horizontal water turbine nozzle structure, including:

[0008] A crescent-shaped housing, wherein the crescent-shaped housing has an internal mounting cavity;

[0009] V-shaped impeller, the V-shaped impeller includes a impeller disk and several V-shaped blades, the impeller disk is disposed in the mounting cavity, and the several V-shaped blades are arranged around the outside of the impeller disk, and the "V" shaped openings of each V-shaped blade are in the same direction;

[0010] One or more nozzles are provided on the crescent-shaped housing, and a nozzle mounting port is provided that communicates with the mounting cavity. The rotary disk has a central axis that passes vertically through its center point. The angle between the line connecting the nozzle mounting port and the center of the rotary disk and the central axis is between 50 degrees and 130 degrees. The nozzle is mounted on the nozzle mounting port and faces the V-shaped blade.

[0011] In this application, the nozzle is connected to the high-pressure input pipeline of the self-circulating integrated hydraulic station. The high-pressure water flow can enter the installation cavity from the nozzle and directly impact the V-shaped blades of the turbine runner, thereby driving the turbine runner to rotate faster. The turbine runner drives the turbine's generator bulb through the rotating shaft to work, realizing hydroelectric power generation.

[0012] By setting the nozzle angle as described above, the V-shaped blades can maximize the catch of the water jet from the nozzle, reducing water waste. At the same time, it can also prevent the weight of the water jet from creating resistance to the rotation of the rotor, maximizing the use of water energy and improving power generation efficiency.

[0013] Furthermore, two nozzle mounting ports are provided, one vertically positioned at a 50-degree angle to the central axis, and the other obliquely positioned at a 105-degree angle to the central axis, such that both nozzle mounting ports are tangent to the outer circumference of the rotary disk. By positioning the nozzle mounting ports at 50 and 105 degrees to the central axis of the rotary disk, and ensuring that both nozzle mounting ports are tangent to the outer circumference of the rotary disk, the weight of the water flow can be prevented from creating resistance to the rotation of the rotary disk, thus maximizing the utilization of the water flow's energy.

[0014] Further, the crescent-shaped housing includes a first crescent-shaped housing, a first circular housing, a first injection guide housing, a second injection guide housing, a second crescent-shaped housing, and a second circular housing. The first crescent-shaped housing and the second crescent-shaped housing are arranged opposite to each other, and the first circular housing and the second circular housing are arranged opposite to each other. The outer side of the first circular housing is installed on the inner side of the first crescent-shaped housing. The outer side of the second circular housing is installed on the inner side of the second crescent-shaped housing. The first injection guide housing is fastened to the inner side of the edges of the second crescent-shaped housing and the first crescent-shaped housing. The second injection guide housing is seamlessly connected to the first injection guide housing and fastened to the inner side of the edges of the second crescent-shaped housing and the first crescent-shaped housing. The nozzle mounting port is opened on the first injection guide housing.

[0015] Furthermore, the V-blade impeller also includes a water-blocking ring. The impeller disc is mounted on the inner wall of the water-blocking ring, and several V-shaped blades are arranged around the center line of the arc surface of the outer circumference of the water-blocking ring, with one end of each V-shaped blade connected to the outer wall of the water-blocking ring. When water flows into the V-shaped blades, the water-blocking ring can cooperate with the V-shaped blades to form a water storage groove, thereby preventing water from flowing out of the V-shaped blades and improving the utilization rate of the water flow.

[0016] The beneficial effects of this utility model are as follows: Compared with the prior art, by setting the angle and position of the nozzle, this application enables the V-shaped blade to maximize the reception of the water flow sprayed from the nozzle, thereby reducing water waste; at the same time, it can also avoid the weight of the water flow from causing resistance to the rotation of the turntable, thereby maximizing the utilization of the water flow's energy and improving power generation efficiency.

[0027] In this application, the nozzle 4 is connected to the high-pressure input pipeline of the self-circulating integrated hydraulic station. The high-pressure water flow can enter the installation cavity from the nozzle 4 and directly impact the V-shaped blades 32 of the turbine runner 31, thereby driving the turbine runner 31 to rotate faster. The turbine runner 31 drives the turbine's generator ball to work through the rotating shaft, realizing hydroelectric power generation.

[0028] The crescent-shaped shell 1 is adapted to the shape of the circular rotating disk 31, and can form a flow channel around the V-shaped blade 32 inside. The crescent-shaped shell 1 can block the water flow in the flow channel, thereby preventing water from splashing out and improving the utilization rate of water flow.

[0029] By setting the above angle, the nozzle 4 can maximize the ability of the V-shaped blade 32 to receive the water flow sprayed from the nozzle 4, thereby reducing water waste. At the same time, it can also prevent the weight of the water flow from causing resistance to the rotation of the rotary disk 31, thus maximizing the use of water energy and improving power generation efficiency.

The second injection guide housing 14 is seamlessly connected to the first injection guide housing 13 and fastened to the inner side of the edges of the second crescent-shaped housing 15 and the first crescent-shaped housing 11. The nozzle mounting port 5 is opened on the first injection guide housing 13. The above structure facilitates the assembly of the crescent-shaped housing 1, thereby facilitating the installation of the rotary disk 31.

[0032] Furthermore, the V-blade impeller 3 also includes an impeller water-blocking ring 33. The impeller disk 31 is mounted on the inner wall of the impeller water-blocking ring 33.
