Description
Technical Field
[0001] The present application relates to the technical field of hydropower generation, and in particular to a spiral water turbine and a flow guide assembly. Background Art
[0002] Hydropower is a sustainable energy supply and a sustainable energy solution that can provide a large amount of clean and stable electricity. Hydropower stations can flexibly adjust water flow and power generation according to grid demand, reduce dependence on fossil fuels, and ensure stable supply. Hydropower is environmentally friendly. Hydropower does not require the burning of any fuel, so it produces almost no greenhouse gas emissions such as carbon dioxide. As an environmentally friendly way of power generation, it is of great significance to mitigate climate change and improve air quality.
[0003] At present, my country's technical level in the field of hydropower generation is also constantly improving, which has also greatly promoted the development of my country's hydropower generation technology and further improved my country's research progress in hydropower generation equipment. The research on hydropower generation is mainly focused on the research of turbines, and research technologies in other fields at home and abroad are also constantly being applied to the research and development and improvement of turbines in hydropower generation.
[0004] For example, in the existing Chinese patent with the publication number CN206917798U, a hydroelectric composite axial flow turbine is disclosed, which includes a generator, a water inlet guide pipe, a bucket runner chamber, a negative pressure backflow prevention chamber, a spiral runner chamber and a water outlet guide pipe, wherein the generator is arranged above the bucket runner chamber, the water inlet guide pipe is connected to the bucket runner chamber, the bucket runner chamber is arranged above the negative pressure backflow prevention chamber, the negative pressure backflow prevention chamber is arranged above the spiral runner chamber, and the water outlet guide pipe is arranged below the spiral runner chamber. Through the above-mentioned prior art, the bucket runner and the spiral runner can be driven to rotate in sequence by water flow flushing, so as to drive the water turbine shaft to rotate, and the generator is operated to generate electrical energy.
[0005] However, the above prior art has the following technical defects:
[0006] When the above-mentioned prior art is in operation, water at a high place enters the Pelton runner chamber through the first water inlet guide pipe and the second water inlet guide pipe, and the water flow washes the Pelton runner blades, causing the Pelton runner and driving the turbine shaft to rotate; the water flow passes through the Pelton runner blades, enters the spiral runner chamber, drives the turbine shaft to rotate through the spiral runner, and works on the generator to generate electrical energy. The water flow passes through the Pelton runner blades, and enters the negative pressure backflow prevention chamber from the backflow prevention plate guide hole of the Pelton runner chamber, and then continues along the backflow prevention plate guide hole of the negative pressure backflow prevention chamber to enter the spiral runner chamber. After multiple layers of flow, the energy of the water flow has been greatly weakened, and the water flow is dispersed and it is difficult to effectively drive the spiral runner to rotate, and even if it rotates, the efficiency generated is low.
[0007] Secondly, since the rotation efficiency of the spiral impeller of the above device is low, it mainly relies on the rotation of the upper bucket impeller to drive the water turbine shaft to rotate, and work on the generator to generate electricity. When water enters the bucket impeller chamber through the first water inlet guide pipe and the second water inlet guide pipe, and flushes the bucket impeller blades to rotate the bucket impeller, it only acts on the bucket impeller through the natural flow of water to make it rotate; on the one hand, the force of the naturally flowing water flow is limited, and on the other hand, the water flow entering the bucket impeller chamber through the first water inlet guide pipe and the second water inlet guide pipe is relatively dispersed and cannot be concentrated on the bucket impeller blades, resulting in the water flow passing through the above device. It is difficult to efficiently drive the water turbine shaft to rotate and work on the generator.
[0008] Based on this, on the basis of the existing hydroelectric composite axial flow turbine, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

DETAILED DESCRIPTION
[0040] The following is combined with Figure 1-Figure 13 This application is described in further detail.
[0041] The embodiment of the present application discloses a spiral water turbine and a guide assembly, which can centrally guide the water flow during the hydroelectric power generation process so that the water flow acts on the hydroelectric power generation equipment more efficiently, and can be applied to different water environments to meet a variety of usage scenarios.
[0042] The embodiment of the present application provides a spiral water turbine to solve the problem in the prior art that water flow dispersion leads to low rotation efficiency of the water turbine shaft, making it difficult to efficiently drive the water turbine shaft to rotate and perform work on the generator.
[0043] Embodiment 1:
[0044] Reference Figure 1 and Figure 2 As shown, the present application provides a spiral water turbine, comprising a linkage shaft 1 and a cone 11 mounted on one end of the linkage shaft 1, wherein the cone 11 is fixedly mounted on one end of the linkage shaft 1; a guide mechanism 2 is provided on the cone 11 and the linkage shaft 1, which is used to centrally guide the water flow through the cone 11. When in use, one end of the linkage shaft 1 is mounted on the power generation equipment, and under the action of the guide mechanism 2, the linkage shaft 1 can be driven to rotate efficiently by the flow of water, and the rotation of the linkage shaft 1 can do work on the power generation equipment to generate electrical energy.
[0045] The guiding mechanism 2 includes two spiral blades 21 installed around the cone 11 and having a diameter that changes with the cone 11. A conical cylindrical flow guide cover 22 is provided at the cone 11. The conical cylindrical flow guide cover 22 is symmetrically inclined with two mounting plates 23 at one end toward the linkage shaft 1. The two mounting plates 23 and the conical cylindrical flow guide cover 22 are fixedly connected; the mounting plate 23 is provided with an escape port 231, which is conducive to the flow of water and reduces the blocking effect of the mounting plate 23 on the water flow; the mounting plate 23 is provided with an assembly component 3 for quickly mounting the conical cylindrical flow guide cover 22 on the linkage shaft 1.
[0046] The conical cylindrical flow guide cover 22 is installed on the linkage shaft 1 through the assembly component 3, and is covered around the cone 11 and the two spiral blades 21. When the water flows from the head end with a smaller diameter of the conical cylindrical flow guide cover 22 to the end with a larger diameter, the water flow can be more concentrated and efficiently flow from the tip of the two spiral blades 21 on the cone 11 to the end, and the cone 11 and the linkage shaft 1 are driven to rotate by the convergence and orderly flow of the water flow at the two spiral blades 21 on the cone 11.
[0047] Reference Figure 2 and Figure 3 As shown, considering that the conical cylindrical flow deflector 22 needs to be installed on the linkage shaft 1 so that the water flow can continuously act on the spiral blade 21, the assembly component 3 includes a main telescopic rod 31 and a secondary telescopic rod 32 installed on the side of the mounting plate 23 facing the linkage shaft 1, and the two mounting plates 23 are both installed with the main telescopic rod 31 and the secondary telescopic rod 32 on the side facing the linkage shaft 1; the telescopic ends of the main telescopic rod 31 and the secondary telescopic rod 32 are connected with an arc-shaped fitting rod 33, and the arc-shaped fitting rod 33 is fixedly connected with the telescopic ends of the main telescopic rod 31 and the secondary telescopic rod 32. When the arc-shaped fitting rod 33 is stressed, the main telescopic rod 31 and the secondary telescopic rod 32 can telescopically adjust the distance between the arc-shaped fitting rod 33 and the linkage shaft 1 to be suitable for linkage shafts 1 of different diameters. The mounting plate 23 is provided with an assembly lock rod 34 that is rotatable, and the mounting plate 23 is provided with a plug hole 232 for installing the assembly lock rod 34.
[0048] By rotating the assembly locking rod 34, the arc-shaped fitting rod 33 can be driven to press against the connecting shaft 1. By rotating the two assembly locking rods 34 respectively, the two arc-shaped fitting rods 33 can be driven to press against the connecting shaft 1 to achieve a fixed clamping effect, so as to achieve the effect of detachably installing the conical cylindrical air guide cover 22 on the connecting shaft 1 through the mounting plate 23, so that the conical cylindrical air guide cover 22 is always covered on the periphery of the cone 11 and the two spiral blades 21.
[0049] Reference Figure 3As shown, the insertion end of the assembly locking rod 34 has a threaded portion 35. It should be noted that the diameter of the threaded portion 35 is smaller than the main body of the assembly locking rod 34. A through hole 331 is provided on the arc-shaped fitting rod 33 for the threaded portion 35 of the assembly locking rod 34 to pass through. The shape of the through hole 331 allows the threaded portion 35 to pass through, and the main body of the assembly locking rod 34 will be abutted in the through hole 331. The linkage shaft 1 is symmetrically provided with an internal threaded hole 101 that is compatible with the threaded portion 35 of the assembly locking rod 34. During installation, the conical guide cover 22 is sleeved on the outer periphery of the cone 11 and the two spiral blades 21, so that the arc-shaped fitting rod 33 stays at the connection hole 331 and is aligned with the position of the internal thread hole 101, and then the assembly lock rod 34 is rotated to rotate the threaded portion 35 into the internal thread hole 101, so that the assembly lock rod 34 and the linkage shaft 1 are threadedly connected, and under the shape limitation of the connection hole 331, the main body of the assembly lock rod 34 abuts against the connection hole 331, so as to realize the arc-shaped fitting rod 33 against the linkage shaft 1. The device in this embodiment is placed horizontally as shown in the figure, which is suitable for centralized guidance of water flow in open waters.
[0050] Embodiment 2:
[0051] Reference Figure 4 As shown, on the basis of the first embodiment, in order to be applicable to the water flow environment falling from a height, the naturally flowing water flow is centrally guided so that the water flow acts more efficiently and centrally on the spiral blade 21, thereby improving the rotation efficiency of the linkage shaft 1. A water collecting unit 4 is also provided at one end of the conical cylindrical flow guide cover 22 away from the mounting plate 23. In this embodiment, the water collecting unit 4 preferably includes a side outer ring 42 mounted on the end of the conical cylindrical flow guide cover 22 through three L-shaped pads 41. The equipment of this embodiment is placed vertically and is suitable for water areas where water flows from a height. Through the cooperation of mounting equipment such as bolts and the three L-shaped pads 41, when in use, the side outer ring 42 is fixedly mounted on the side walls of other surrounding facilities and is located at the upper end of the conical cylindrical flow guide cover 22.
[0052] Reference Figure 5 and Figure 6As shown, in order to gather the water flow falling from a high place into the conical cylindrical flow deflector 22 and prevent the water flow from being too dispersed and reducing the force on the spiral blades 21, the inner wall of the side outer ring 42 is provided with a conical portion 43 with a diameter gradually reduced from top to bottom, and the bottom side of the side outer ring 42 is provided with an annular shell 44 that is covered outside the conical portion 43, and an inclined cavity 401 is provided between the annular shell 44 and the conical portion 43. The side outer ring 42 is at the upper end of the conical cylindrical flow deflector 22, and the annular shell 44 and the conical portion 43 extend into the conical cylindrical flow deflector 22. It should be noted that the side outer ring 42, the annular shell 44, the conical portion 43 and the conical cylindrical flow deflector 22 are on the same central axis. The water flow falling from a high place can be concentrated into the conical cylindrical flow deflector 22 and flushed on the two spiral blades 21 under the gathering of the side wall of the conical portion 43. Avoid the water flow entering the conical cylindrical flow deflector 22 from being too dispersed.
[0053] Reference Figures 7 to 9 As shown, since the energy of naturally flowing water is limited and depends on the falling height and is uncertain, in order to ensure the rotation efficiency of the linkage shaft 1, when the falling height of the water flow is low and the force of the water flow automatically flowing and scouring the spiral blade 21 is small, a part of the water flow can be temporarily stored. After a certain amount of water is accumulated, it is uniformly discharged to the spiral blade 21 to improve the rotation efficiency of the linkage shaft 1. An annular liquid storage box 46 is slidably installed in the inclined cavity 401 through the two side blocks 45, and rectangular openings 441 for sliding installation of the two side blocks 45 are symmetrically opened on the annular shell 44, and a control component 5 is provided at the bottom of the side outer ring 42 for controlling the downward and upward movement of the annular liquid storage box 46.
[0054] A plurality of water collecting ports 431 communicating with the inclined cavity 401 are formed in an annular manner on the side wall of the conical portion 43, a guide ring 47 is formed on the inner wall of the conical portion 43 below the water collecting ports 431, a plurality of water inlets 461 communicating with the inner cavity are formed on the inner wall of the annular liquid storage box 46, an annular water outlet 462 is formed below the water inlet 461, and an inclined ring 48 is formed at the bottom of the inner cavity of the annular liquid storage box 46. In the process of water flowing through the conical portion 43 and entering the conical cylindrical guide cover 22, a part of the water flow will enter the annular liquid storage box 46 through the water collecting port 431 and the water inlet 461 under the obstruction of the guide ring 47. Under the action of the control component 5, when a certain amount of water is stored in the annular liquid storage box 46, the annular liquid storage box 46 can automatically slide down, and the lower half of the annular liquid storage box 46 extends out of the inclined cavity 401. At this time, the water stored in the annular liquid storage box 46 can be discharged outward through the annular water outlet 462, so that a large amount of stored water can be concentrated on the two spiral blades 21, so that the two spiral blades 21 can be subjected to a higher energy force, thereby driving the cone 11 and the linkage shaft 1 to rotate more efficiently.
[0055] The tilting ring 48 is fixedly mounted on the bottom of the inner cavity of the annular liquid storage box 46 , and the upper side of the tilting ring 48 is tilted, which can drive the water stored in the annular liquid storage box 46 to be discharged more quickly and concentratedly.
[0056] Reference Fig.10 and Fig.11 As shown, considering the need to control the position of the annular liquid storage box 46, when a certain amount of water is stored, the annular liquid storage box 46 can automatically move down to discharge the temporarily stored water through the annular water outlet 462. When the water flow inside the annular liquid storage box 46 is discharged, the annular liquid storage box 46 can be automatically driven to move up and reset to store water again. The control component 5 includes a limiting round rod 51 symmetrically installed at the bottom of the side outer ring 42 and respectively passing through the two side blocks 45. The two limiting round rods 51 are fixedly connected to the side outer ring 42; the side blocks 45 are penetrated with a supply The limiting rod 51 penetrates the rod hole 451, and the limiting rod 51 located above the side block 45 is provided with a first magnet 52. The side block 45 is embedded with a second magnet 53 that attracts the first magnet 52. In the initial state, the first magnet 52 and the second magnet 53 attract each other. At this time, the annular liquid storage box 46 is located at the highest position, and each water inlet 461 on the annular liquid storage box 46 overlaps and communicates with the corresponding water collection port 431, and the water flow can enter the inner cavity of the annular liquid storage box 46 through the water collection port 431 and the water inlet 461. The upper side of the side block 45 has a rectangular groove 452 for installing the second magnet 53.
[0057] It should be noted that the first magnet 52 is fixedly mounted on the limiting rod 51, and the suction force between the first magnet 52 and the second magnet 53 is relatively strong. Only when more than three-quarters of the volume of water is stored in the annular liquid storage box 46, the weight at this time can force the second magnet 53 to separate from the first magnet 52. When a certain amount of water is stored in the annular liquid storage box 46, it can automatically move downward to discharge the water through the annular water outlet 462.
[0058] Reference Fig.12As shown, a circular magnet 1 54 is arranged at the bottom end of the limiting rod 51, a circular magnet 2 55 which repels the circular magnet 1 54 is embedded and installed at the lower side of the side block 45, and a concave groove 453 is provided at the lower side of the side block 45 for installing the circular magnet 2 55, and a push spring 56 is sleeved on the limiting rod 51 between the circular magnet 1 54 and the circular magnet 2 55. The push spring 56 always has a driving force to push the side block 45 upward. It should be noted that the repulsive force between the circular magnet 1 54 and the circular magnet 2 55 plus the pushing force of the push spring 56 is relatively small in total. Only when the water stored in the annular liquid storage box 46 is discharged, the annular liquid storage box 46 can be pushed upward by the side block 45 under the repulsive force and the driving force of the push spring 56, and return to the initial position under the suction of the first magnet 52 and the second magnet 53 to collect the stored water again. Repeated circulation ensures that when the natural water flow falls at a low height and the force acting on the spiral blades 21 is small, the linkage shaft 1 can still rotate efficiently through the storage of water in the annular liquid storage box 46, thereby providing protection for power generation efficiency.
[0059] Embodiment three:
[0060] The embodiment of the present application provides a flow guide assembly, including the contents of the spiral water turbine described in the above-mentioned embodiment 1 and embodiment 2. The details will not be repeated here.
[0061] Embodiment 4:
[0062] Reference Fig.13 As shown, on the basis of the second and third embodiments, in order to facilitate the operator to install the side outer ring 42 at the best position, so that the water discharged from the annular liquid storage box 46 flushes the spiral blade 21 at the best angle, and can provide a guarantee for the smooth rotation of the conical cylindrical flow guide cover 22, and at the same time can minimize the friction between the side outer ring 42 and the conical cylindrical flow guide cover 22, a number of round balls 49 are arranged on the bottom side of the side outer ring 42 for equidistant rotation, and a number of limiting circular grooves 421 for limiting the installation of the round balls 49 are opened on the bottom side of the side outer ring 42. In order to facilitate the staff to select the position height, when installing the side outer ring 42, the side outer ring 42 is directly placed on the upper end of the conical cylindrical flow guide cover 22, so that the round balls 49 collide with the upper side of the conical cylindrical flow guide cover 22.
[0063] On the one hand, under the resistance of multiple round balls 49, the upper side of the conical cylindrical air guide cover 22 has a force, which can make the conical cylindrical air guide cover 22 rotate more smoothly with the linkage shaft 1; on the other hand, when installing, the staff directly places the side outer ring 42 on the upper end of the conical cylindrical air guide cover 22, and the conical part 43 and the annular shell 44 are inserted into the conical cylindrical air guide cover 22. Each round ball 49 can be in resistance with the upper side of the conical cylindrical air guide cover 22, and the side outer ring 42 does not need to directly contact the upper side of the conical cylindrical air guide cover 22, thereby reducing the friction between the two, making the conical cylindrical air guide cover 22 more stable and smooth when rotating. At the same time, when the annular liquid storage box 46 stores a sufficient amount of water, it moves down and concentrates on draining water onto the spiral blades 21 to ensure that the water flow flushes the spiral blades 21 at the optimal angle to avoid excessive distance between the bottom of the side outer ring 42 and the upper end of the conical cylindrical air guide cover 22, which causes the annular liquid storage box 46 to drain water at an excessively high angle, resulting in less force on the spiral blades 21.
[0064] The implementation principle of this embodiment is:
[0065] (1) Connection and installation: The conical cylindrical air guide cover 22 is sleeved on the outer periphery of the cone 11 and the two spiral blades 21. The assembly locking rod 34 is rotated to rotate the threaded portion 35 into the internal threaded hole 101. The assembly locking rod 34 is threadedly connected to the linkage shaft 1, and the conical cylindrical air guide cover 22 is stably installed on the linkage shaft 1 through the tight contact of the two arc-shaped fitting rods 33.
[0066] (2) Converging and guiding: The water flow is guided by the inner conical portion 43 of the side outer ring 42, so that the water flow converges and flows into the conical cylindrical guide cover 22, and is concentrated on the spiral blades 21. The conical cylindrical guide cover 22 can make the water flow more concentrated and efficiently flow from the tips of the two spiral blades 21 on the cone 11 to the end.
[0067] (3) Integrated storage: When water flows through the conical portion 43 and converges into the conical cylindrical flow guide cover 22, a portion of the water flows through the water collection port 431 and the water inlet 461 and enters the annular liquid storage box 46 to be centrally stored under the obstruction of the guide ring 47.
[0068] (4) Unified discharge: When a certain amount of water is stored in the annular liquid storage box 46, the annular liquid storage box 46 moves downward and extends out of the inclined cavity 401, and the stored water is discharged outward through the annular water outlet 462. A large amount of stored water is concentrated on the two spiral blades 21, so that the two spiral blades 21 are subjected to a higher energy force, thereby driving the linkage shaft 1 to rotate more efficiently.
