Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine generators, and specifically to a vertical-axis wind tourism sightseeing generator set with a concrete tower. Background Art

[0002] Traditional horizontal-axis wind turbine generators are usually restricted by the wind direction and require relatively complex mechanical rotating devices to capture and convert wind energy. Vertical-axis wind turbine generators have certain advantages under certain environmental conditions due to their simple structure and being not restricted by the wind direction. However, there is still room for improvement in the wind energy capture efficiency and mechanical stability of existing vertical-axis wind turbine generators. For example, when an existing vertical-axis wind turbine generator operates in the normal horizontal direction, a large reverse resistance will be generated on the arc surface of the reverse wind blades under the blowing resistance of the wind, which will seriously affect the power generation efficiency of the vertical-axis wind turbine generator. Summary of the Invention

[0003] To solve the above technical problems, the present invention is achieved through the following technical solutions: A vertical-axis wind tourism sightseeing generator set with a concrete tower, including a concrete tower, which is located at the central position of the generator set. The whole concrete tower is made of high-strength and lightweight materials to ensure the stability and load-bearing capacity of the whole structure. The diameter of the concrete tower is set moderately, which can not only provide sufficient support but also not increase too much resistance. It also includes:

[0004] A multi-layer blade assembly, which is distributed around the concrete tower with different radii. The multi-layer blade assembly is used for the hierarchical guidance of wind. The multi-layer blade assembly includes a support frame assembly installed on the concrete tower, and the number of the support frame assemblies is three groups.

The wind guiding assembly includes a top support frame, and the top support frame is rotatably installed on the top of the concrete tower. A wind guiding body is installed around the side of the top support frame in a circular shape, and the inside of the wind guiding body is hollow. The wind guiding body is used to guide the wind upward to the first wind blade assembly and the second wind blade assembly. That is, the wind guiding assembly is located upstream of the multi-layer blade assembly and is used to guide the wind flow to pass through the multi-layer blade assembly smoothly. Among them, the whole wind guiding assembly adopts a streamline curved surface design to reduce wind resistance and ensure the stability, uniformity, and smoothness of wind guiding at the same time.

[0006] Preferably, the first wind blade assembly includes first blades which are evenly distributed along the circumference on the side of the support frame assembly. The number of the first blades is three groups, and the tops of the three groups of first blades are all located directly below the air guide body.

[0007] Preferably, the second wind blade assembly includes second blades which are evenly distributed along the circumference on the side of the support frame assembly.

[0010] Preferably, the support frame assembly includes a wind wheel disc rotatably installed on a concrete tower. The side of the wind wheel disc is fixedly connected with first cross beams in a circular array. The side of the wind wheel disc is installed with second cross beams in a circular array, and the second cross beams are arranged at an equal arc length interval with the first cross beams. Among them, the second cross beams have the same structure as the first cross beams, and the second cross beams are shorter than the first cross beams.

[0011] Preferably, corner blocks are fixedly connected in a circular array on the side of the wind wheel disc. The corner blocks are located between the first cross beams and the second cross beams, and the number of the corner blocks is three groups. And from a top view angle, the blades and the support frame assembly are partially in an equilateral triangle shape, so that when the multi-layer blade assembly operates as a whole, it can ensure that the concrete tower is in a balanced stress state as a whole and guarantee the normal operation of the wind turbine generator set; a double-headed screw is threadedly installed in the middle of the corner block. One end of the double-headed screw away from the wind wheel disc is installed with a sealing piece.

The annular tooth cavity is used to increase the fusion welding contact area between the pin head and the solder. The bolt is threadedly installed with the pin head through the first cross beam. The first blade is attached to the first cross beam through the notch, so that the blade structure and the cross beam structure can be attached and installed, and the blade will not be directly and abruptly assembled on the cross beam, increasing the contact installation area between the two, and improving the stability and structural strength during the operation of the blade.

[0014] Preferably, the overall shape of the air guide body is a Möbius ring design, and the longitudinal section of the air guide body is triangular. The air guide body has three sets of circulating guiding surfaces. Among them, the air guide assembly further includes annular stirrups, and the number of annular stirrups is three. The annular stirrups are integrally provided with the air guide body along the three sets of circulating guiding surfaces of the air guide body, serving as the guiding and supporting framework of the air guide body.

[0015] Preferably, the top support frame has an extension frame, and the extension frame is fixedly connected to the side of the top support frame in a circular array. One end of the extension frame away from the top support frame is fixedly connected to a support rod, and the support rod is fixedly connected to the inside of the air guide body.

[0017] The present invention provides a vertical-axis wind-tourism sightseeing type generator set with a concrete tower, having the following beneficial effects:

[0018] First, for this vertical-axis wind-tourism sightseeing type generator set with a concrete tower, through the overall use of the Möbius ring-shaped curved surface air guiding structure of the air guide body, airflows from different directions can be uniformly guided to the inside of the air guide body on its three surfaces that circulate, reverse, and transform, and then, through the blade structure adjacent to the bottom of the air guide body, the airflows are dispersed and guided, so as to realize the unified guiding function of the air guide body for the wind, be able to guide and disperse the wind energy in different directions, and realize the effective promotion and conversion of the wind energy to the air guide assembly.

[0019] Second, for the vertical-axis wind-tourism sightseeing generator set with a concrete tower, by means of a hollow air guide body, while reducing the self-weight of the air guide body, the structural strength and toughness at the edge of the air guide body are enhanced by using annular stirrups. At the same time, the sharp edges at the edge of the air guide body are eliminated. With the annular stirrup structure with a curved surface cooperating with the three curved surfaces of the air guide body, the air resistance of the air guide body itself is reduced, enabling the air flow to smoothly flow along the guidance of the air guide body.

[0020] Third, for the vertical-axis wind-tourism sightseeing generator set with a concrete tower, through the connection setting of the triangular support inside the air guide body and the annular stirrup, while providing support for the installation of the annular stirrup on the air guide body at the end angle part, it can also provide strong support for the three curved surfaces on the inner side of the air guide body. By utilizing the stability of the triangle, while strengthening the overall structural strength of the air guide body, effective support for the curved surfaces in all directions of the air guide body is achieved, improving the wind pressure resistance performance of the air guide body itself, and ensuring the air flow guiding performance of the air guide body itself. While ensuring the overall structural strength of the air guide body, the overall mass of the air guide body can be reasonably controlled, and the weight balance control of the entire concrete tower is realized.

[0021] Fourth, for the vertical-axis wind-tourism sightseeing generator set with a concrete tower, while horizontally fixing and supporting the air guide body on the top of the concrete tower through the top support frame combined with the support rod, by using the support rod as the structure where the air guide body contacts the top support frame, the blocking effect of the support structure of the top support frame on the air flow guiding path is weakened, ensuring the smoothness and fluidity of the air flow guiding into the air guide body; through the extension frame, the structural connection strength between the support rod and the top support frame is further strengthened and consolidated, enabling the support rod to combine with the top support frame and, together with the air guide body, withstand the impacts from various angles of the wind energy. The air guide assembly can adapt to the air flow impacts at different azimuth angles, can adapt to complex and changeable wind directions, can realize the unified guidance and collection of the air flow in different angle wind directions, and achieve the effective utilization of wind energy.

[0022] Fifth, for the vertical-axis wind-tourism sightseeing generator set with a concrete tower, by setting the air guide assembly upstream of the blades, before the wind direction enters the blade area, the air flow can be guided and collected, improving the utilization efficiency of wind energy.

[0023] Sixth, for the vertical-axis wind-tourism sightseeing generator set with a concrete tower, through the design of the inner support plate, after the blades are welded to the crossbeam structure with solder, the inner support plate can be welded to the blades as a whole, while extending the contact area between the blades and the crossbeam structure, it can provide a pulling force in the lateral direction for the blades, strengthening the installation strength between the blades and the crossbeam structure, and also enhancing the structural strength inside the crossbeam, ensuring the safe use of the blades and the crossbeam structure.

[0024] VII. The vertical-axis wind-tourism sightseeing generator set of the concrete tower, through the design of the annular tooth cavity, can make the solder after melting fill the entire annular tooth cavity in a surrounding serrated shape, so that the solder can form an annular serrated stirrup structure on the surface of the pin head, further enhancing the assembly and bonding strength of the blade on the crossbeam structure, and avoiding the problem of local loosening caused by the extrusion deformation of the blade when encountering strong wind.

[0025] VIII. The vertical-axis wind-tourism sightseeing generator set of the concrete tower, through the setting of the notch, can well fit and assemble the blade with the corresponding crossbeam structure. After the pin head is inserted inside the metal thin sleeve and thread-connected with the bolt, the solder can be welded around the notch by the way of concentrating the heating on the fitting part of the crossbeam and the blade, so that the solder can fill on the pin head, annular tooth cavity, bolt, inner support plate and notch, welding the blade and the crossbeam into a whole. By using the method of first installing with thread positioning and then strengthening the overall bonding strength of the connecting part with solder, the double reinforcement installation of the blade and the crossbeam is realized, the bonding strength of the blade and the crossbeam is improved, and the safe use performance of the blade is improved.

[0026] IX. The vertical-axis wind-tourism sightseeing generator set of the concrete tower, through the additional installation points provided by the angle block, adaptively installs an additional second crossbeam structure, and can further install a crossbeam structure shorter than the second crossbeam to stagger-install the blade with a smaller radius at the position between the first blade and the second blade, so as to further expand the area of the guiding contact section of the multi-layer blade assembly for the air flow, further improve the conversion efficiency of the multi-layer blade assembly for wind energy, and can be selectively installed and used in combination with the specific application scenario of the wind power generator set, the specific wind energy resources in the area where the wind power generator set is located, and the overall quality and load of the wind power generator set during operation, so that the wind power generator set can be applied under different working conditions.

[0027] X. For the vertical-axis wind-tourism sightseeing generator set of the concrete tower, the blades on the support frame assembly are staggeredly distributed around the concrete tower in different radii, so as to effectively expand the guiding contact section of the top of the multi-layer blade assembly for the wind direction, improve the conversion of wind energy, and improve the utilization efficiency of wind energy.

Blue transparent glass is installed at the four surrounding frame positions of each layer. There is a staircase between each layer, which is convenient to reach the top of the concrete tower 1 for the maintenance of the generator set.

[0048] The support frame assembly 21 includes a wind wheel disc 211 rotatably installed on the concrete tower 1. The side of the wind wheel disc 211 is fixedly connected with first cross beams 212 in a circular array. The side of the wind wheel disc 211 is installed with second cross beams 213 in a circular array, and the second cross beams 213 are arranged at an equal arc length interval with the first cross beams 212. Among them, the second cross beams 213 have the same structure as the first cross beams 212, and the second cross beams 213 are shorter than the first cross beams 212.

[0049] The sides of the wind wheel disc 211 are fixedly connected with corner blocks 216 in a circular array. The corner blocks 216 are located between the first cross beam 212 and the second cross beam 213, and the number of the corner blocks 216 is three groups. A double-headed screw 214 is threadedly installed in the middle of the corner block 216. One end of the double-headed screw 214 away from the wind wheel disc 211 is installed with a sealing piece 215. The sealing piece 215 is fitted and installed in the middle of the corner block 216 for shielding and protecting the double-headed screw 214. The second cross beam 213 is threadedly installed with the wind wheel disc 211 through the cooperation of the double-headed screw 214 and the corner block 216. Among them, the second cross beam 213 is fitted with the corner block 216.

[0050] An opening 121 is provided at one end of the first cross beam 212 away from the wind wheel disc 211. A bolt 122 is threadedly installed on the side of the first cross beam 212 facing away from the first blade 220, and the bolt 122 is correspondingly installed on one side of the opening 121.

The bolt 122 is threadedly installed with the inner support plate 125, and the inner support plate 125 is in contact with the solder 123.

[0051] The overall shape of the air guide body 32 is designed in a Mobius ring shape, and the longitudinal section of the air guide body 32 is triangular. The air guide body 32 has three groups of circulating guiding surfaces. Among them, the air guide assembly 3 further includes annular stirrups 33, and the number of the annular stirrups 33 is three groups. The annular stirrups 33 are integrally arranged with the air guide body 32 along the three groups of circulating guiding surfaces of the air guide body 32, serving as the guiding and supporting framework of the air guide body 32. A triangular support frame 34 is fixedly installed inside the air guide body 32 along the trend of the circulating guiding surface, and the three end parts of the triangular support frame 34 are respectively fixedly connected with the three groups of annular stirrups 33.

[0052] A disc 11 is fixedly installed at the top of the concrete tower 1. The top support frame 31 is fixedly installed with the concrete tower 1 through the disc 11. The air guide body 32 is fixedly installed with the concrete tower 1 through the top support frame 31. Among them, the air guide body 32 is used to guide the wind onto the first blade 220 and the second blade 230.

[0053] The application of the present invention is mainly in large vertical-axis wind turbines. When in use, before the wind direction enters the blade area of the multi-layer blade assembly 2 through the air guiding assembly 3, by using the air guiding body 32 designed with a Möbius ring structure, the wind direction towards its inner part from all around can be guided smoothly to the first blade 220 and the second blade 230 of the multi-layer blade assembly 2, so that the wind guided by the air guiding body 32 can be evenly divided into multiple strands and guided onto each stagger-arranged blade. By using the wind shunted and guided to act on the blades, the multi-layer blade assembly 2 is pushed to rotate on the concrete tower 1, thereby realizing the operation of the wind turbine generator.

[0054] The blades on the support frame assembly 21 are staggeredly distributed around the concrete tower 1 in different radii, so as to effectively expand the contact guiding cross-section of the top of the multi-layer blade assembly 2 with the wind direction, improve the conversion of wind energy, and enhance the utilization efficiency of wind energy.

[0055] Before use, additional installation points provided by the angle block 216 can be used to adaptively install an additional second cross beam 213 structure. A cross beam structure shorter than the second cross beam 213 can be further installed to staggeredly install the blades with a smaller radius between the first blade 220 and the second blade 230, so as to further expand the area of the guiding contact cross-section of the multi-layer blade assembly 2 with the air flow, further improve the conversion efficiency of the multi-layer blade assembly 2 for wind energy, and can be selectively installed and used in combination with the specific application scenario of the wind turbine generator, the specific wind energy resources in the area where the wind turbine generator is located, and the overall mass and load of the wind turbine generator during operation, so that the wind turbine generator can be applied under different working conditions.

[0056] When the angle block 216 is not enabled, the front end of the double-headed screw 214 is blocked by the sealing piece 215, and the double-headed screw 214 is blocked and protected inside the angle block 216 to prevent dust from clogging or polluting the double-headed screw 214 and affecting the later use.

[0057] By adopting the curved surface air guiding structure of the Möbius ring for the whole air guiding body 32, air flows from different directions can be uniformly guided to the inner side of the air guiding body 32 on its three curved surfaces with cyclic flipping and transformation, and the air flow is dispersed and guided through the blade structure next to the bottom of the air guiding body 32, so as to realize the unified guiding function of the air guiding body 32 for the wind, guide and disperse the wind energy in different directions, and realize the effective pushing and conversion of the wind energy on the air guiding assembly 3.

[0058] By means of the air guide body 32 with a hollow structure, while reducing the weight of the air guide body 32 itself, the structural strength and toughness at the edges of the air guide body 32 are strengthened by using the annular stirrup 33. At the same time, the sharp corners at the edges of the air guide body 32 are eliminated. With the annular stirrup 33 structure with a curved surface cooperating with the three curved surfaces of the air guide body 32, the air resistance of the air guide body 32 itself is reduced, enabling the air flow to flow smoothly along the guidance of the air guide body 32.

[0059] Through the connection setting of the triangular support 34 inside the air guide body 32 and the annular stirrup 33, while providing support at the end corners for the installation of the annular stirrup 33 on the air guide body 32, it can also provide strong support for the three curved surfaces on the inner side of the air guide body 32. Utilizing the stability of the triangle, while strengthening the overall structural strength of the air guide body 32, it realizes effective support for the curved surfaces in all directions of the air guide body 32, improves the wind pressure resistance performance of the air guide body 32 itself, and ensures the air flow guiding performance of the air guide body 32 itself. While ensuring the overall structural strength of the air guide body 32, it can reasonably control the overall mass of the air guide body 32, and realize the weight balance control of the overall concrete tower 1.

[0060] By arranging the air guide assembly 3 upstream of the blade, before the wind direction enters the blade area, it can guide and converge the air flow, improving the utilization efficiency of wind energy.

[0061] Through the above design, the concrete tower vertical axis wind tourism sightseeing type generator set of the present invention has the following advantages:

[0062] It can improve the utilization efficiency of wind energy: The design of the multi-layer blade assembly 2 and the air guide assembly 3 effectively increases the capture area and utilization efficiency of wind energy, and improves the overall performance of the generator set.

[0063] It can reduce the structural complexity: Compared with the traditional horizontal axis wind turbine generator set, the structure of the present invention is simpler, reducing the number and complexity of mechanical components, lowering the manufacturing cost and maintenance difficulty, solving the wind noise problem during the operation of the wind turbine, and improving the power generation efficiency.

[0064] It can enhance the mechanical stability: The central setting of the concrete tower 1 and the staggered arrangement design of the blades effectively reduce the mechanical vibration and structural stress under the action of wind force, improve the stability and safety of the generator set, and increase the service life of the generator set.

[0065] Second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 8As shown in the figure, on one side of the first blade 220 facing the notch 121, two groups of pin heads 221 are fixedly connected. An annular tooth cavity 222 is formed in the middle of the pin head 221, and the annular tooth cavity 222 is formed in a circular sawtooth shape on the pin head 221. The annular tooth cavity 222 is used to increase the fusion welding contact area between the pin head 221 and the solder 123. The bolt 122 is threadedly installed with the pin head 221 through the first cross beam 212, and the first blade 220 is attached to the first cross beam 212 through the notch 121.

[0066] During use, due to the setting of the notch 121, the blade can be well attached and assembled with the corresponding cross beam structure. After the pin head 221 is inserted inside the metal thin sleeve 124 and threadedly connected with the bolt 122, the solder 123 can be fusion welded around the notch 121 by concentrating heat on the fitting part of the cross beam and the blade, so that the solder 123 can fill the pin head 221, the annular tooth cavity 222, the bolt 122, the inner support plate 125 and the notch 121, welding the blade and the cross beam into a whole. By first performing threaded positioning and installation, and then using the solder 123 to strengthen the overall bonding strength of the connection part, the double reinforcement installation of the blade and the cross beam is realized, the bonding strength between the blade and the cross beam is improved, and the safe use performance of the blade is enhanced.

[0067] Through the design of the annular tooth cavity 222, the molten solder can be filled in the entire annular tooth cavity 222 in a surrounding sawtooth shape after heat melting, so that the solder can form an annular sawtooth-shaped stirrup structure on the surface of the pin head 221, further enhancing the assembly bonding strength of the blade on the cross beam structure and avoiding the problem of local loosening caused by the extrusion deformation of the blade when encountering strong wind.

[0068] Through the design of the inner support plate 125, after the solder welds the blade and the cross beam structure together, the inner support plate 125 can be welded with the blade into a whole. While extending the combined contact area between the blade and the cross beam structure, it can provide a pulling force in the horizontal direction for the blade, strengthen the installation strength between the blade and the cross beam structure, and also improve the internal structural strength of the cross beam, ensuring the safe use of the blade and the cross beam structure.

[0069] For the third embodiment, on the basis of the first and second embodiments, please refer to Figure 12 As shown in the figure, the top support frame 31 has an extension frame 311. The extension frame 311 is fixedly connected to the side of the top support frame 31 in a circular array. One end of the extension frame 311 away from the top support frame 31 is fixedly connected with a support rod 312. The support rod 312 is fixedly connected to the inside of the air guide body 32. The top support frame 31 is provided with air holes 313 in a circular array, which are used to reduce the mass of the top support frame 31, reduce the wind resistance of the top support frame 31, and at the same time ensure that the air flow will not be completely blocked by the top support frame 31 and cannot be smoothly guided onto the blade.

[0070] In use, while the air guiding body 32 is horizontally fixed and supported at the top of the concrete tower 1 through the top support frame 31 in combination with the support rod 312, the support rod 312 is used as the structure where the air guiding body 32 contacts the top support frame 31 to weaken the blocking effect of the support structure, i.e., the top support frame 31, on the air flow guiding path, ensuring the smoothness and fluidity of the air flow guiding into the air guiding body 32; the extension frame 311 is used to further strengthen and consolidate the structural connection strength between the support rod 312 and the top support frame 31, enabling the support rod 312 to be combined with the top support frame 31 and, together with the air guiding body 32, withstand the impacts from various angles of the wind energy, so that the air guiding assembly 3 can adapt to the air flow impacts at different azimuth angles, can adapt to complex and changeable wind directions, can achieve the unified guiding and collection of the air flow at different angles of the wind direction, and can effectively utilize the wind energy.
