Description

Technical Field

[0001] The present invention relates to the technical field of hydroelectric power generation equipment, in particular to turbine-type hydroelectric power generation equipment and a power generation method based on a pressurized water inlet pipeline. Background Art

[0002] Hydropower generation primarily utilizes the potential energy stored in water bodies. To convert this energy into electricity, various types of hydropower stations are required. The basic principle of hydropower generation is to utilize water level differences in conjunction with hydroelectric generators to generate electricity. This involves converting the potential energy of water into mechanical energy in the turbines, which in turn drives the generators to generate electricity. Currently, as the middle route of the South-to-North Water Diversion Project passes through the North China Plain, utilizing the allocated water resources from the South-to-North Water Diversion Project to build a provincial water supply network in North China will not only facilitate water use for rural life and production in northern China, but will also significantly benefit groundwater extraction in the region.

[0003] Among them, in the supporting water networks such as the water plants, supporting trunk canals (such as Baocang trunk canal, Xingqing trunk canal, Langzhuo trunk canal, etc.), and dedicated pipelines (dedicated pipelines supporting major water users, such as dedicated pipelines supporting Shahe Power Plant and Dingzhou Development Zone, etc.) in the river water replacement project for domestic water sources located in the downstream of the South-to-North Water Diversion Project, while ensuring the supply of daily water pressure, there is still some water potential energy loss. In order to utilize this part of the water potential energy, a small power generation equipment is installed in the pressurized water inlet pipeline at the tail end of the South-to-North Water Diversion Project to fully utilize the remaining water energy to convert it into electrical energy.

[0004] Since most of the current small-scale power generation equipment is installed in the branch pipes of the pressurized water inlet pipes, and in the water plant at the end of the South-to-North Water Diversion Project, due to the large number and density of pressurized water inlet pipes, it is difficult to utilize the water pressure when a large number of small-scale power generation equipment are installed when the water pressure is insufficient. This can easily lead to a large amount of idle time for the power generation equipment, unstable power generation power and time, and easy impact on the power grid. Summary of the Invention

Then, the water flows through the bottom drainage mechanism and is input back to the corresponding pressurized water inlet pipe from each drainage branch pipe.

[0021] While the driving rotor rotates, it also drives the generating rotor to rotate inside the magnetic power generation mechanism to generate electricity.

[0022] Compared with the prior art, the present invention provides a turbine-type hydroelectric power generation equipment and a power generation method based on a pressurized water inlet pipeline, which has the following beneficial effects:

[0023] 1. In this turbine-type hydroelectric power generation equipment, after water flows into each liquid inlet flow channel and is guided by each guide blade, the setting of each liquid inlet flow channel of the vortex spiral flow channel can ensure that the water flow can be evenly divided by the guidance of each guide blade, and output to the driving rotor at the same flow rate to impact and drive the driving rotor to rotate. While the driving rotor rotates, it can drive the generating rotor to rotate inside the magnetic power generation mechanism to generate electricity. The input water flow is finally collected by the bottom drainage mechanism and then divided into several water flows and output separately, so that the water flow energy input from each liquid inlet flow channel can be stably utilized, and the stability of the driving rotor's rotation speed is ensured by the guidance of each guide blade and the uniform diversion of the vortex spiral flow channel, thereby ensuring the stability of the power generated by the generating rotor rotating inside the magnetic power generation mechanism, while ensuring the power generation effect, avoiding the fluctuation of the generated power and affecting the stability of the power grid.

[0024] 2. This type of turbine-type hydroelectric power generation equipment first accumulates the water flow input from each input pipe through a liquid collecting tank, and outputs the liquid inside the liquid collecting tank to each liquid inlet channel at the same flow rate, the same flow rate and the same output height through the action of the distributor. It can also control the distributor to ensure the stability of the water flow output from each liquid inlet channel when the water flow in the input pipe is unstable, and ensure the uniform diversion of the driving rotor through the guidance of each guide blade and the vortex spiral flow channel by making the total length and height difference of each liquid inlet channel equal, thereby effectively avoiding the influence of unstable water flow caused by fluctuations in downstream water consumption on the stability of power generation, and can also ensure that the liquid output from the overall drainage mechanism can be distributed by the diversion drainage mechanism and output to multiple drainage branches respectively, thereby ensuring the uniformity of the water flow output from each drainage branch, thereby ensuring effective water flow supply to the downstream, ensuring water consumption downstream and ensuring the stability of power generation.

[0025] 3. This turbine-type hydroelectric power generation equipment, by extending the coordinated cylinder, brings the coordinated pressing plate into contact with the top of the rotating drive rack. Under the drive of the drive cylinder, the angle between each guide vane and the centerline of the vortex is synchronously adjusted with the angle between each rotor blade and the vertical plane. By shortening the coordinated cylinder and maintaining the separation between the coordinated pressing plate and the rotating drive rack during the process of the coordinated pressing plate being driven by the drive cylinder to move, the angle between each rotor blade and the vertical plane can be synchronously adjusted by the drive cylinder, and the angle between each guide vane and the centerline of the vortex can be synchronously adjusted by the synchronous adjustment of the gear ring. Therefore, through the above-mentioned coordinated control and separate control, the angle between each guide vane and the centerline of the vortex can be dynamically and synchronously adjusted according to the actual water flow rate, thereby effectively ensuring the mutual matching of water flow rate and power generation, and improving the power generation effect.

[0026] 4. This power generation method based on a pressurized water inlet pipe ensures the safety of the water supply to the water plant by leading out a liquid inlet branch pipe and a liquid discharge branch pipe from the pressurized water inlet pipe. When the equipment is operating normally, the water inlet to the water plant is fed through a bypass pipe. If the equipment is under maintenance or fails, the water inlet is switched back to the original pressurized water inlet pipe to ensure the stability of the water supply to the water plant. By adopting the setting of multiple liquid inlet flow channels 11, the combined water flow of multiple pressurized water inlet pipes is fully utilized, the water inlet volume is increased to ensure the power generation power, while reducing the investment in power generation equipment and saving the cost of utilizing the remaining water energy.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a turbine-type hydroelectric power generation equipment and a power generation method based on a pressurized water inlet pipeline.

[0041] Example 1:

[0042] See also Figures 1-11 A turbine type hydroelectric power generation device includes a top liquid inlet mechanism 1, a middle fixed shell 2 and a bottom liquid discharge mechanism 3, characterized in that: a driving rotor 4 is rotatably arranged inside the middle fixed shell 2, and the top liquid inlet mechanism 1 is arranged on the top outer side of the middle fixed shell 2; a magnetic power generation mechanism 5 is arranged above the middle fixed shell 2, and a power generation rotor 6 is rotatably arranged inside the magnetic power generation mechanism 5, and the driving rotor 4 and the power generation rotor 6 are coaxially fixed; the top liquid inlet mechanism 1 includes a plurality of liquid inlet flow channels 11, each of which is wound around the middle On the outside of the fixed shell 2, each liquid inlet flow channel 11 is a vortex spiral flow channel, and the cross-section of each liquid inlet flow channel 11 decreases successively from the head end to the tail end; each liquid inlet flow channel 11 is provided with a plurality of guide blades 111 on the side close to the driving rotor 4. After the water flow input from the head end of each liquid inlet flow channel 11 is guided by each guide blade 111, it is output to the driving rotor 4 at the same flow rate, thereby impacting and driving the driving rotor 4 to rotate; while the driving rotor 4 rotates, it can drive the generating rotor 6 to rotate inside the magnetic power generation mechanism 5 to generate electricity.

[0043] When in use, each liquid inlet channel 11 can be connected to a plurality of water inlet pipes (a turbine-type hydroelectric power generation device in this embodiment can operate in the optimal power generation range when water with the same water pressure is input from each liquid inlet channel 11). After the water is input from each liquid inlet channel 11 and guided by each guide blade 111, the setting of each liquid inlet channel 11 of the vortex spiral flow channel can ensure that the water flow can be evenly diverted after being guided by each guide blade 111, and output to the driving rotor 4 at the same flow rate, thereby impacting and driving the driving rotor 4 to rotate, and the driving rotor 4 rotates, and can drive the power generation rotor 6 to rotate inside the magnetic power generation mechanism 5 to generate electricity. The input water flow is finally collected by the bottom drainage mechanism 3 and then divided into several water flows for output respectively, so that the water flow energy input from each liquid inlet flow channel 11 can be stably utilized. The guidance of each guide blade 111 and the uniform flow distribution of the vortex spiral flow channel ensure the stability of the rotation speed of the driving rotor 4, thereby ensuring the stability of the power generated by the rotation of the power generation rotor 6 inside the magnetic power generation mechanism 5. While ensuring the power generation effect, it is avoided that the fluctuation of the generated power affects the stability of the power grid.

[0044] Example 2:

[0045] See also Figures 1-11 The difference from the above embodiment is that, preferably, the top liquid inlet mechanism 1 also includes a flow distributor, which can be connected to each liquid inlet branch respectively, and the liquid input by each liquid inlet branch can enter the liquid inlet distributor 12; the bottom drainage mechanism 3 includes an overall drainage mechanism 31 and a diversion drainage mechanism 32, and the liquid output from the overall drainage mechanism 31 can be distributed by the diversion drainage mechanism 32 and output to multiple drainage branches respectively; each liquid inlet branch corresponds to a drainage branch, and the corresponding liquid inlet branch and drainage branch are respectively connected to a main pipeline.

[0046] Preferably, the flow distributor includes a liquid collecting tank and a liquid distributor, each liquid inlet branch is respectively connected to the liquid collecting tank, and liquid can be input into the liquid collecting tank from each liquid inlet branch. The distributor can output the liquid inside the liquid collecting tank to each liquid inlet channel 11 at the same flow rate, the same flow rate and the same output height; the total length of each liquid inlet channel 11 is the same, and the height difference between the head end and the tail end of each liquid inlet channel 11 is also equal.

[0047] During specific use, the water flow input from each input pipe is first accumulated through the liquid collecting tank, and the liquid inside the liquid collecting tank is output to each liquid inlet channel 11 at the same flow rate, the same flow rate and the same output height through the action of the distributor (the liquid collecting tank and the distributor in this embodiment are both common technical solutions in the prior art). By controlling the distributor, when the water flow in the input pipe is unstable, the stability of the water flow output from each liquid inlet channel 11 can be guaranteed. By making the total length and height difference of each liquid inlet channel 11 equal, the uniform diversion of the guide blades 111 and the vortex spiral flow channel can be guaranteed, thereby ensuring the stability of the rotation speed of the driving rotor 4. This can effectively avoid the influence of the unstable water flow caused by the fluctuation of the water consumption in the downstream on the stability of power generation. The liquid output from the overall drainage mechanism 31 can be distributed by the diversion drainage mechanism 32 and output to multiple drainage branches respectively, thereby ensuring the uniformity of the water flow output from each drainage branch, thereby ensuring the effective water flow supply to the downstream, ensuring the water consumption in the downstream and ensuring the stability of power generation.

[0048] Example 3:

[0049] See also Figures 1-11 , the difference from the above embodiment is that the liquid inlet channel 11 has a vortex centerline, and the angle between each guide blade 111 and the vortex centerline is consistent; a deflection rod 112 is provided at one end of each guide blade 111, and the deflection rod 112 passes through the liquid inlet channel 11, and a driving gear 113 is provided at one end of the deflection rod 112 located outside the liquid inlet channel 11; a synchronous adjustment ring gear 12 is provided outside the circle surrounded by each driving gear 113, and the synchronous adjustment ring gear 12 is meshed with each driving gear 113 at the same time. By driving the synchronous adjustment ring gear 12 to rotate, the angle between each guide blade 111 and the vortex centerline can be driven to be adjusted synchronously.

[0050] The driving rotor 4 includes a rotor shell 41 and a plurality of rotor blades 42. Each guide blade 111 corresponds to a rotor blade 42. A connecting turntable 43 is provided at one end of the rotor blade 42 close to the rotor shell 41. The connecting turntable 43 is embedded in the surface of the rotor shell 41. The angle between each rotor blade 42 and the vertical plane is consistent. Each connecting turntable 43 is rotationally connected to the rotor shell 41, and a seal is maintained between the rotor shell 41 during the rotation of each connecting turntable 43.

[0051] Each connecting turntable 43 is located on one side of the rotor housing 41 and is rotatably provided with a rotating connecting rod 44. Each rotating connecting rod 44 is rotatably connected to the lifting drive disk 46 through a lifting connecting rod 45. The lifting drive disk 46 is controlled by the driving cylinder 47. During the up and down lifting of the lifting drive disk 46, each connecting turntable 43 rotates synchronously to drive the angle between each rotor blade 42 and the vertical plane to be adjusted synchronously.

[0052] A cooperative adjustment mechanism 7 is provided on the inner side of the circle surrounded by each driving gear 113, and the cooperative adjustment mechanism 7 includes a cooperative driving ring gear 71, a rotating amplifying gear 72 and a rotating driving rack 73; the outer side of the cooperative driving ring gear 71 is simultaneously meshed with each driving gear 113, and the top of the cooperative driving ring gear 71 is meshed with the rotating amplifying gear 72, and the rotating amplifying gear 72 is coaxially fixed with a driven gear 74, and the rotating driving rack 73 is meshed with the driven gear 74; a return spring 75 is provided at the bottom end of the rotating driving rack 73, and a cooperative driving plate 48 is also provided on the outer side of the movable end of the driving cylinder 47, and a cooperative pressing plate 482 is provided at the bottom end of the cooperative driving plate 48 via a cooperative cylinder 481.

[0053] When the angles between each guide vane 111 and the centerline of the volute are coordinated with the angles between each rotor blade 42 and the vertical plane, the extension of the coordination cylinder 481 causes the coordination pressing plate 482 to abut against the top end of the rotation drive rack 73. Under the drive of the drive cylinder 47, the angles between each guide vane 111 and the centerline of the volute are adjusted synchronously with the angles between each rotor blade 42 and the vertical plane.

[0054] When the angle between each guide blade 111 and the center line of the vortex and the angle between each rotor blade 42 and the vertical plane are controlled separately, the coordinated cylinder 481 is shortened, and in the process of the driving cylinder 47 driving the coordinated pressing plate 482 to move, the coordinated pressing plate 482 is kept disengaged from the rotating driving rack 73, and the angle between each rotor blade 42 and the vertical plane can be synchronously adjusted by driving the driving cylinder 47, and the angle between each guide blade 111 and the center line of the vortex can be synchronously adjusted by synchronously adjusting the gear ring 12.

[0055] Therefore, through the above-mentioned coordinated control and separate control, the angle between each guide blade 111 and the center line of the vortex can be dynamically and synchronously adjusted according to the actual water flow rate (the potential energy of the water), thereby effectively ensuring the mutual matching of the water flow rate and the power generation power, and improving the power generation effect.

[0056] The integral drainage mechanism 31 is arranged at the bottom end of the driving rotor 4. The inner diameter of the integral drainage mechanism 31 increases and then decreases from top to bottom, thereby avoiding cavitation damage to the rotor blades 42 of the driving rotor 4; the power generation rotor 6 can rotate with the rotation of the driving rotor 4, and cut the magnetic lines of force inside the magnetic power generation mechanism 5 to generate electricity during the rotation of the power generation rotor 6.

[0057] Example 4:

[0058] A method for generating electricity based on a pressurized water inlet pipeline, using a turbine-type hydroelectric power generation device as described in any one of Embodiments 1 to 3, comprises the following steps:

[0059] A liquid inlet branch pipe and a liquid discharge branch pipe are respectively led out from each pressurized water inlet pipe, and control valves are arranged on the pressurized water inlet pipe, the liquid inlet branch pipe and the liquid discharge branch pipe;

[0060] Connect each liquid inlet branch pipe to the liquid inlet channel 11, and connect each liquid discharge branch pipe to the bottom liquid discharge mechanism 3;

[0061] Close the control valves of each pressurized water inlet pipe, and open the control valves of each liquid inlet branch pipe and each liquid discharge branch pipe;

[0062] Each pressurized water inlet pipe outputs water from the corresponding liquid inlet branch pipe to the liquid inlet channel 11. After being guided by the guide blades 111, the water is output to the driving rotor 4 at the same flow rate, thereby impacting and driving the driving rotor 4 to rotate. The water then passes through the bottom drainage mechanism 3 and is input back to the corresponding pressurized water inlet pipe from the drainage branch pipe.

[0063] While the driving rotor 4 rotates, the power generation rotor 6 is driven to rotate inside the magnetic power generation mechanism 5 to generate electricity.

[0064] By leading out a liquid inlet branch pipe and a liquid discharge branch pipe from a pressurized water inlet pipe, a turbine-type hydroelectric power generation equipment as described in any one of Examples 1 to 3 is implemented under the premise of ensuring the water supply safety of the water plant. When the equipment is operating normally, the water plant enters the water plant through a bypass pipe. If the equipment is under maintenance or fails, the water is switched back to the original pressurized water inlet pipe to ensure the stability of the water supply of the water plant. By adopting the setting of multiple liquid inlet channels 11, the combined water flow of multiple pressurized water inlet pipes is fully utilized, the water inlet volume is increased to ensure the power generation power, while reducing the number of power generation equipment invested and saving the cost of utilizing the remaining water energy.

[0065] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
