Description

Technical Field

[0001] The present invention relates to the technical field of wind energy towers, and particularly relates to a wind energy tower with a multi-stage eddy current acceleration function. Background Art

[0002] A wind energy tower is a relatively common wind power generation device. By installing a generator in the wind energy tower, it relies on the natural wind to drive the wind energy blades to rotate for power generation.

[0003] When the existing wind energy tower equipment is in use, since the wind speeds at different heights are different, the speeds at which the natural wind drives the wind energy blades to rotate are also different. This method is likely to cause different wind forces on the blades at different heights, and even the blades with larger wind forces need to drive the blades with smaller wind forces to rotate, thus directly reducing the utilization rate of wind energy. Therefore, a wind energy tower with a multi-stage eddy current acceleration function is proposed to facilitate the automatic startup of the wind power generation equipment corresponding to different heights, thereby improving the utilization rate of wind energy. Summary of the Invention

[0004] Aiming at the problems in the prior art, the present invention provides a wind energy tower with a multi-stage eddy current acceleration function, which is convenient for automatically starting the wind power generation equipment corresponding to different heights, thereby improving the utilization rate of wind energy.

[0005] The technical solution adopted by the present invention to solve its technical problems is a wind energy tower with a multi-stage eddy current acceleration function, including a support platform. The upper part of the support platform is provided with a wind energy tower body, the bottom of the support platform is provided with several groups of support legs, a water storage pool is provided below the support platform, and a water storage tank is provided at the top of the wind energy tower body.

[0006] Several groups of air inlets are equally spaced and distributed on the outer side of the wind energy tower body. A vertically arranged cavity is provided inside the wind energy tower body, and several groups of the air inlets are all communicated with the cavity. Several groups of wind-powered water pump structures corresponding to the air inlets are equally spaced up and down on the inner side of the cavity. The wind-powered water pump structures rely on wind energy to pump the water in the water storage pool into the water storage tank, and a water conservancy power generation mechanism is communicated between the water storage pool and the water storage tank.

[0007] By adopting the above technical solution, when the wind energy enters the cavity through the air inlets, it relies on the wind energy to drive the wind-powered water pump structures to operate. When the wind-powered water pump structures are driven, the water in the water storage pool is pumped into the water storage tank, and the water output from the water storage tank drives the water conservancy power generation mechanism to generate electricity.

[0008] Since the wind speeds at different heights are inconsistent, when the winds at different heights enter the air inlets, they drive the wind-powered water pump structures corresponding to the air inlets to operate. The wind-powered water pump structures at different heights pump the water in the water storage pool into the water storage tank at different speeds, and rely on the water output from the water storage tank to drive the water conservancy power generation mechanism to operate, thereby improving the utilization rate of wind energy.

[0009] Specifically, the structure of the wind-powered water pump includes a first vortex pump. The water inlets of the first vortex pump are all connected to the bottom of the water storage tank through pipelines. The first vortex pump includes a hollow shaft, and a vortex impeller is slidably connected to the upper side of the hollow shaft up and down.

[0010] By adopting the above technical solution, when wind energy enters the cavity through the air inlet, it drives the vortex blades to rotate. When the vortex blades rotate, they drive the hollow shaft to rotate. When the hollow shaft rotates, it drives the first vortex pump. Relying on the drive of the first vortex pump, the water in the water storage tank enters the first vortex pump through the water inlet pipe, so as to drive the first vortex pump to operate through wind energy and vortex blades.

[0011] It should be noted that the first vortex pumps described in the present invention are all connected to the water storage tank through independent water inlet pipes.

[0012] Specifically, a chute is connected to the upper side of the hollow shaft. The vortex impeller includes a hollow cylinder and vortex blades connected to the outside of the hollow cylinder. Side plates are connected to both the upper and lower sides of the vortex blades, and a convex rib slidably connected to the chute is connected to the inside of the hollow cylinder.

[0013] By adopting the above technical solution, when wind energy enters the cavity through the air inlet and drives the vortex blades to rotate, relying on the sliding connection between the convex rib inside the hollow cylinder and the chute on the hollow shaft, the rotation of the hollow cylinder drives the hollow shaft to rotate. When the hollow shaft rotates, it drives the first vortex pump to operate.

[0014] Specifically, the water power generation mechanism includes a water power generator. The top of the water power generator is connected to the water storage tank through a first connecting pipe, and the bottom of the water power generator is connected to the water storage tank through a second connecting pipe.

[0015] By adopting the above technical solution, when the water in the water storage tank is pumped into the water storage tank through the wind-powered water pump structure, relying on the first connecting pipe, the water in the water storage tank enters the water power generator, so as to drive the water power generator to generate electricity. At the same time, relying on the second connecting pipe installed at the bottom of the water power generator, the water in the water power generator enters the water storage tank through the second connecting pipe, and the work is repeated for power generation operation.

[0016] Specifically, telescopic structures are installed on the tops of the first vortex pumps. The telescopic structure includes an annular shell installed on the upper part of the first vortex pump. An annular cavity with an upward opening is provided inside the annular shell. One side of the bottom of the annular cavity is communicated with the water outlet of the first vortex pump through a pipeline, and the other side of the bottom of the annular cavity is communicated with the top of the water storage tank through an upper water pipe. An annular plate is hermetically and slidably connected inside the annular cavity. A return spring is connected between the lower surface of the annular plate and the bottom of the annular cavity. A support rod is connected to the upper surface of the annular plate, and the upper end of the support rod is connected to a support plate. A roller is installed on the upper surface of the support plate, and the roller is in rolling contact with the lower surface of the side plate.

[0017] By adopting the above technical solution, when the first vortex pump is driven, the water body in the storage pool enters the first vortex pump through the water inlet pipe and enters the annular cavity through the communication port. Relying on the water body to drive the annular plate to be hermetically and slidably connected inside the annular cavity, the annular plate moves upward. When the annular plate moves upward, one end of the return spring is driven to move upward and store energy. When the annular plate moves upward, the support rod is driven to move upward synchronously. When the support rod moves upward, the support plate is driven to move upward. When the support plate moves upward to a certain position, the roller installed on the support plate makes moving contact with the lower surface of the side plate. Relying on the rolling contact between the roller and the side plate, and at the same time relying on the continuous upward movement of the support plate to drive the side plate to move upward, the upper water pipe installed on one side of the annular cavity conveys the water body in the annular cavity to the water storage tank.

[0018] When the wind speed outside the wind energy tower body is small, relying on the reset function of the return spring, the annular plate can be driven to move downward and reset.

[0019] When the wind energy outside the wind energy tower body is strong, in order to prevent the vortex blades from being damaged during high-speed rotation. When the wind energy is strong, the speed of driving the vortex blades to rotate is also stronger, so that the pumping effect of the first vortex pump on the storage pool is stronger, the outlet water pressure increases. And when the water body enters the annular cavity, relying on the water body to drive the annular plate to move upward and finally drive the side plate to move upward. When the side plate moves upward, the positions of the vortex blades and the air inlet are staggered, thereby reducing the driving effect on the vortex blades and reducing the rotation speed of the vortex blades, effectively preventing the vortex blades from being damaged in strong wind weather.

[0020] It should be noted that in the initial state, the vortex blades correspond to the air inlet. As the pumping speed of the wind-powered water pump structure increases, the vortex blades are driven to move upward. When the wind speed is large, the vortex blades and the air inlet are staggered to reduce the wind force received by the vortex blades and avoid damage to the vortex blades.

[0021] Specifically, a standby water pump structure is provided below the support platform near the water storage tank. The standby water pump structure includes a second vortex pump. The water inlet of the second vortex pump is connected to the water storage tank through a pipeline, and the water outlet of the second vortex pump is connected to the water storage tank through a pipeline. A vertically installed rotating shaft is provided in the middle of the second vortex pump. The rotating shaft sequentially passes through several groups of hollow shafts. A first annular gear with a downward-facing tooth surface is installed inside the hollow cylinder. A second annular gear corresponding to the first annular gear is installed on the rotating shaft. The tooth surface of the second annular gear faces upward. The first annular gear and the second annular gear are meshed and driven.

[0022] By adopting the above technical solution, in the normal use state, when the first vortex pump conveys water to the annular cavity, it drives the annular plate to move upward. Relying on the upward movement of the annular plate, the side plate is driven to move upward. When the side plate moves upward, it drives the hollow cylinder to move upward, causing the hollow cylinder to slide relative to the hollow shaft. When the hollow cylinder moves upward, the first annular gear inside the hollow cylinder and the second annular gear installed on the rotating shaft are no longer meshed. Thus, the water in the annular cavity is conveyed to the water storage tank through the water supply pipe.

[0023] When one of the first vortex pumps is damaged and unable to work, the water in the water storage tank cannot enter the damaged first vortex pump. At this time, the corresponding vortex blade will not move upward and will continue to rotate by wind energy. Relying on the meshing drive between the second annular gear installed on the rotating shaft and the first annular gear installed on the hollow cylinder, the vortex blade drives the second vortex pump to work, and the water in the water storage tank is conveyed into the second vortex pump through the water inlet, and the water in the second vortex pump is conveyed to the water storage tank through the water outlet, thus ensuring the stability of the wind energy tower operation.

[0024] Specifically, check valves for single-direction water outlet are installed at the water outlets of the first vortex pump and the second vortex pump.

[0025] By adopting the above technical solution, relying on the check valve can effectively prevent the water in the first vortex pump and the second vortex pump from flowing back into the water storage tank. Before use, an appropriate amount of water needs to be added to the first vortex pump and the second vortex pump, so as to facilitate driving the first vortex pump or the second vortex pump to convey the water in the water storage tank to the water storage tank by the rotation of the vortex blade.

[0026] The beneficial effects of the present invention:

[0027] The wind energy tower with a multi-stage vortex acceleration function described in the present invention can rely on wind energy to drive the wind-powered water pump structure to operate. When the wind-powered water pump structure is driven, the water in the water storage tank is pumped into the water storage tank, and the water outlet of the water storage tank drives the hydraulic power generation mechanism to generate electricity;

[0028] A wind energy tower with a multi-stage vortex acceleration function according to the present invention can automatically lift the vortex blades upward when the wind energy water pump structure pumps water, so that the transmission between the first ring gear and the second ring gear is disconnected. At this time, the second vortex pump will not be driven to operate by the rotation of the vortex blades;

[0029] Moreover, when the wind speed is too high and the rotation speed of the vortex blades is relatively large, the vortex blades are further lifted to adjust the relative positional relationship between the vortex blades and the air inlet, so as to reduce the driving effect of the air inlet air on the vortex blades, thereby avoiding the damage caused by the too fast operation speed of the wind energy water pump structure when the wind speed is too high.

[0030] For a damaged set of first vortex pumps in the wind energy tower with a multi-stage vortex acceleration function according to the present invention, since water cannot be supplied to the annular cavity, the vortex blades cannot be lifted. At this time, the vortex blades will always be driven by the first ring gear and the second ring gear, so as to pump water through the second vortex pump, avoiding the corresponding vortex blades from stopping working due to the damage of the first vortex pump 8 and affecting the wind energy utilization rate.

DETAILED DESCRIPTION OF THE INVENTION

[0038] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0039] As Figures 1-5 shown, a wind energy tower with a multi-stage vortex acceleration function according to the present invention includes a support platform 1. An upper part of the support platform 1 is provided with a wind energy tower body 2. A bottom of the support platform 1 is provided with several groups of support legs 3. A water storage pool 4 is provided below the support platform 1. A water storage tank 5 is provided at the top of the wind energy tower body 2;

[0040] Several groups of air inlets 6 are equally spaced and distributed on the outer side of the wind energy tower body 2. A vertically arranged cavity 7 is provided inside the wind energy tower body 2. Several groups of the air inlets 6 are all communicated with the cavity 7. Several groups of wind-powered water pump structures corresponding to the air inlets 6 are equally spaced up and down on the inner side of the cavity 7. The wind-powered water pump structures rely on wind energy to pump the water in the water storage pool 4 into the water storage tank 5. A water conservancy generator structure 16 is communicated between the water storage pool 4 and the water storage tank 5.

[0041] During use, when wind energy enters the cavity 7 through the air inlets 6, it drives the wind-powered water pump structures to operate by relying on the wind energy. When the wind-powered water pump structures are driven, the water in the water storage pool 4 is pumped into the water storage tank 5, and the water storage tank 5 discharges water to drive the water conservancy generator structure 16 to generate electricity;

[0042] Since the wind speeds at different heights are inconsistent, when the wind at different heights enters the air inlets 6, it drives the wind-powered water pump structures corresponding to the air inlets 6 to operate. The wind-powered water pump structures at different heights pump the water in the water storage pool 4 into the water storage tank 5 at different speeds, and rely on the water discharged from the water storage tank 5 to drive the water conservancy generator structure 16 to operate, thereby improving the utilization rate of wind energy.

[0043] As an embodiment of the present invention, the wind-powered water pump structure includes a first vortex pump 8. The water inlets of the first vortex pumps 8 are all connected to the bottom of the water storage pool 4 through pipelines. The first vortex pump 8 includes a hollow shaft 10. A vortex impeller 11 is slidably connected to the upper side of the hollow shaft 10 up and down.

[0044] During use, when wind energy enters the cavity 7 through the air inlets 6, it drives the vortex blades to rotate. When the vortex blades rotate, they drive the hollow shaft 10 to rotate. When the hollow shaft 10 rotates, it drives the first vortex pump 8. Relying on the drive of the first vortex pump 8, the water in the water storage pool 4 enters the first vortex pump 8 through the water inlet pipe, so as to drive the first vortex pump 8 to operate through wind energy and the vortex blades;

[0045] It should be noted that the first vortex pumps 8 described in the present invention are all connected to the water storage pool 4 through independent water inlet pipes.

[0046] As an embodiment of the present invention, a chute 12 is connected to the upper side surface of the hollow shaft 10. The scroll impeller 11 includes a hollow cylinder 13 and scroll blades connected to the outside of the hollow cylinder 13. Side plates 14 are connected to both the upper and lower sides of the scroll blades. A rib 15 that is slidably connected to the chute 12 is connected to the inside of the hollow cylinder 13.

[0047] During use, when wind energy enters the cavity 7 through the air inlet 6 and drives the scroll blades to rotate, relying on the sliding connection between the rib 15 inside the hollow cylinder 13 and the chute 12 on the hollow shaft 10, the rotation of the hollow cylinder 13 drives the hollow shaft 10 to rotate. When the hollow shaft 10 rotates, it drives the first vortex pump 8 to operate.

[0048] As an embodiment of the present invention, the hydroelectric power generation mechanism includes a hydroelectric generator 16. The top of the hydroelectric generator 16 is connected to the water storage tank 5 through a first connecting pipe 17, and the bottom of the hydroelectric generator 16 is connected to the water storage pool 4 through a second connecting pipe 18.

[0049] During use, when the water in the water storage pool 4 is pumped into the water storage tank 5 by the wind-powered water pump structure, relying on the first connecting pipe 17, the water in the water storage tank 5 enters the hydroelectric generator 16, thereby driving the hydroelectric generator 16 to generate electricity. At the same time, relying on the second connecting pipe 18 installed at the bottom of the hydroelectric generator 16, the water in the hydroelectric generator 16 enters the water storage pool 4 through the second connecting pipe 18, and this reciprocating work is carried out for power generation operations.

[0050] As an embodiment of the present invention, a telescopic structure is installed on the top of the first vortex pump 8. The telescopic structure includes an annular shell 19 installed on the upper part of the first vortex pump 8. An annular cavity 20 with an upward opening is provided inside the annular shell 19. One side of the bottom of the annular cavity 20 is connected to the water outlet of the first vortex pump 8 through a pipeline, and the other side of the bottom of the annular cavity 20 is connected to the top of the water storage tank 5 through an upper water pipe 22. An annular plate 23 is hermetically and slidably connected inside the annular cavity 20. A return spring 24 is connected between the lower surface of the annular plate 23 and the bottom of the annular cavity 20. A support rod 25 is connected to the upper surface of the annular plate 23. The upper end of the support rod 25 is connected to a support plate 26. A roller 27 is installed on the upper surface of the support plate 26. The roller 27 is in rolling contact with the lower surface of the side plate 14.

[0051] In use, when the first vortex pump 8 is driven, the water in the water storage tank 4 enters the first vortex pump 8 through the water inlet pipe and enters the annular cavity 20 through the communication port. Driven by the water, the annular plate 23 is hermetically and slidably connected to the annular cavity 20, causing the annular plate 23 to move upward. When the annular plate 23 moves upward, one end of the return spring 24 is driven to move upward and store energy. When the annular plate 23 moves upward, the support rod 25 is driven to move upward synchronously. When the support rod 25 moves upward, the support plate 26 is driven to move upward. When the support plate 26 moves upward to a certain position, the roller 27 installed on the support plate 26 comes into moving contact with the lower surface of the side plate 14. By relying on the rolling contact between the roller 27 and the side plate 14, and at the same time relying on the continuous upward movement of the support plate 26 to drive the side plate 14 to move upward, the water pipe 22 installed on one side of the annular cavity 20 conveys the water in the annular cavity 20 to the water storage tank 5;

[0052] When the wind speed outside the wind energy tower body 2 is relatively low, relying on the reset function of the return spring 24, the annular plate 23 can be driven to move downward and reset;

[0053] When the wind energy outside the wind energy tower body 2 is strong, in order to prevent the vortex blades from being damaged during high-speed rotation, when the wind energy is strong, the speed of driving the vortex blades to rotate is also stronger, so that the pumping effect of the first vortex pump 8 on the water storage tank 4 is stronger, the outlet water pressure increases, and when the water enters the annular cavity 20, the water drives the annular plate 23 to move upward and finally drives the side plate 14 to move upward. When the side plate 14 moves upward, the positions of the vortex blades and the air inlet 6 are staggered, thereby reducing the driving effect on the vortex blades and reducing the rotation speed of the vortex blades, effectively preventing the vortex blades from being damaged in strong wind weather;

[0054] It should be noted that in the initial state, the vortex blades correspond to the air inlet 6. As the pumping speed of the wind-powered water pump structure increases, the vortex blades are driven to move upward. When the wind speed is relatively high, the vortex blades and the air inlet 6 are staggered to reduce the wind force received by the vortex blades and avoid damage to the vortex blades.

[0055] As an embodiment of the present invention, a standby water pump structure is provided below the support platform 1 close to the water storage tank 4. The standby water pump structure includes a second vortex pump 9. The water inlet of the second vortex pump 9 is connected to the water storage tank 4 through a pipeline, and the water outlet of the second vortex pump 9 is connected to the water storage tank 5 through a pipeline. A vertically installed rotating shaft 21 is provided in the middle of the second vortex pump 9. The rotating shaft 21 sequentially passes through several groups of hollow shafts 10. A first annular gear 28 with a downward-facing tooth surface is installed inside the hollow cylinder 13. A second annular gear 29 corresponding to the first annular gear 28 is installed on the rotating shaft 21. The tooth surface of the second annular gear 29 faces upward, and the first annular gear 28 and the second annular gear 29 are meshed and driven.

[0056] In the normal use state of the present invention, when the first vortex pump 8 conveys water into the annular cavity 20, it drives the annular plate 23 to move upward. Relying on the upward movement of the annular plate 23, the side plate 14 is driven to move upward. When the side plate 14 moves upward, it drives the hollow cylinder 13 to move upward, causing the hollow cylinder 13 to slide with the hollow shaft 10. When the hollow cylinder 13 moves upward, the first annular gear 28 in the hollow cylinder 13 is no longer engaged with the second annular gear 29 installed on the rotating shaft 21. Thus, the water is conveyed into the water storage tank 5 through the water supply pipe 22 in the annular cavity 20.

[0057] When one of the first vortex pumps 8 is damaged and unable to work, the water in the reservoir 4 cannot enter the damaged first vortex pump 8. At this time, the corresponding vortex blades will not move upward and will continue to rotate by wind energy. Relying on the meshing transmission between the second annular gear 29 installed on the rotating shaft 21 and the first annular gear 28 installed on the hollow cylinder 13, the vortex blades drive the second vortex pump 9 to work. The water in the reservoir 4 is conveyed into the second vortex pump 9 through the water inlet and the water in the second vortex pump 9 is conveyed into the water storage tank 5 through the water outlet, thus ensuring the stability of the wind energy tower during operation.

[0058] As an embodiment of the present invention, check valves for one-way water outlet are installed at the water outlets of the first vortex pump 8 and the second vortex pump 9.

[0059] By adopting the above technical solution, relying on the check valve, the water in the first vortex pump 8 and the second vortex pump 9 can be effectively prevented from flowing back into the reservoir 4. Before use, an appropriate amount of water needs to be added to the first vortex pump 8 and the second vortex pump 9, so as to facilitate driving the first vortex pump 8 or the second vortex pump 9 to convey the water in the reservoir 4 into the water storage tank 5 by the rotation of the vortex blades.

[0060] When in use, when wind energy enters the cavity 7 through the air inlet 6, the wind energy is relied on to drive the operation of the wind-powered water pump structure. When the wind-powered water pump structure is driven, the water in the reservoir 4 is pumped into the water storage tank 5, and the water outlet of the water storage tank 5 is relied on to drive the operation of the water turbine generator 16 structure.

[0061] Since the wind speeds at different heights are inconsistent, when the wind at different heights enters the air inlet 6, it drives the operation of the wind-powered water pump structure corresponding to the air inlet 6. The wind-powered water pump structures at different heights pump the water in the reservoir 4 into the water storage tank 5 at different speeds, and the water outlet of the water storage tank 5 is relied on to drive the operation of the water turbine generator 16 structure, thereby improving the utilization rate of wind energy.

[0062] When the first vortex pump 8 is driven, the water in the reservoir 4 enters the first vortex pump 8 through the water inlet pipe and enters the annular cavity 20 through the communication port. Driven by the water, the annular plate 23 is in sealed sliding connection with the annular cavity 20, causing the annular plate 23 to move upward. When the annular plate 23 moves upward, one end of the return spring 24 is driven to move upward and store energy. When the annular plate 23 moves upward, the support rod 25 is driven to move upward synchronously. When the support rod 25 moves upward, the support plate 26 is driven to move upward. When the support plate 26 moves upward to a certain position, the roller 27 installed on the support plate 26 comes into moving contact with the lower surface of the side plate 14. By relying on the rolling contact between the roller 27 and the side plate 14, and at the same time, the continuous upward movement of the support plate 26 drives the side plate 14 to move upward, so that the water pipe 22 installed on one side of the annular cavity 20 transports the water in the annular cavity 20 to the water storage tank 5;

[0063] When the wind speed outside the wind energy tower body 2 is relatively low, relying on the reset function of the return spring 24, the annular plate 23 can be driven to move downward and reset;

[0064] When the wind energy outside the wind energy tower body 2 is relatively strong, in order to prevent the vortex blades from being damaged during high-speed rotation, when the wind energy is stronger, the speed of driving the vortex blades to rotate is also stronger, so that the pumping effect of the first vortex pump 8 on the reservoir 4 is stronger, the outlet water pressure increases, and when the water enters the annular cavity 20, driven by the water, the annular plate 23 moves upward and finally drives the side plate 14 to move upward. When the side plate 14 moves upward, the positions of the vortex blades and the air inlet 6 are staggered, thereby reducing the driving effect on the vortex blades and reducing the rotation speed of the vortex blades, effectively preventing the vortex blades from being damaged in strong wind weather.

[0065] Under normal use conditions, when the first vortex pump 8 transports water to the annular cavity 20, the annular plate 23 is driven to move upward. Driven by the upward movement of the annular plate 23, the side plate 14 moves upward. When the side plate 14 moves upward, the hollow cylinder 13 is driven to move upward, causing the hollow cylinder 13 to slide with the hollow shaft 10. When the hollow cylinder 13 moves upward, the first annular gear 28 in the hollow cylinder 13 and the second annular gear 29 installed on the rotating shaft 21 are no longer meshed, so that the water in the annular cavity 20 is transported to the water storage tank 5 through the water pipe 22;

[0066] When one of the first vortex pumps 8 is damaged and cannot work, the water in the reservoir 4 cannot enter the damaged first vortex pump 8. At this time, the corresponding vortex blades will not move upward and will continue to rotate by wind energy. Driven by the meshing transmission between the second annular gear 29 installed on the rotating shaft 21 and the first annular gear 28 installed on the hollow cylinder 13, the vortex blades drive the second vortex pump 9 to work, and the water in the reservoir 4 is transported into the second vortex pump 9 through the water inlet and the water in the second vortex pump 9 is transported to the water storage tank 5 through the water outlet, thus ensuring the stability of the wind energy tower operation.
