Description

Technical Field

[0001] The present invention relates to the technical field of communication towers, and more particularly to a modular vertical axis wind power generation device suitable for communication towers. Background Art

[0002] With the rapid development of communications technology, the density and height of communication towers, core infrastructure for wireless signal coverage, are increasing. However, their energy supply has long relied on the power grid or diesel generators, resulting in high power costs, significant carbon emissions, and difficulty accessing the grid in remote areas. To reduce operating costs and achieve green energy conservation, integrating wind power generation technology with communication towers has become a hot research and development topic in the industry.

[0003] Traditional communication towers typically use a single-tube structure, which leaves the top space underutilized. Vertical axis wind turbines (VAWTs) are becoming the preferred solution for communication tower power supply systems due to their advantages such as low wind speed startup, strong wind direction adaptability, and low noise. However, the existing technology still has the following key issues: The connection between vertical-axis wind turbines and communication towers is mostly done by flange bolting or welding. However, communication towers are subjected to complex stresses such as wind loads and vibrations for a long time. Traditional connectors are prone to loosening due to fatigue or vibration, and may even cause the risk of structural instability.

[0004] Existing connection devices lack self-locking functions and require regular manual inspection and tightening of bolts. This significantly increases the difficulty and cost of maintenance, especially in remote or high-altitude scenarios.

[0005] Traditional installation methods require customized modifications to communication towers, making it impossible to quickly disassemble and modularly replace wind turbines, limiting the versatility and maintainability of the equipment.

[0006] To improve power generation efficiency, the size or weight of the wind rotor needs to be increased, but traditional connection methods make it difficult to balance power generation performance and the structural bearing capacity of the communication tower, which may cause stress concentration or fatigue damage to the tower.

[0007] In recent years, modular design concepts have been widely used in the field of communication equipment, but existing technologies have not yet solved the problem of modular integration of vertical-axis wind turbines and communication towers, especially the lack of a connection device that is self-locking, accurately positioned, and adaptable to complex working conditions.

[0008] Therefore, developing a modular vertical axis wind power generation device suitable for communication towers and solving stability, maintainability and compatibility issues through innovative connection structures is of great significance for promoting the green transformation of communication infrastructure.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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. The present invention is further described below in conjunction with the embodiments.

[0023] See also Figures 1 to 7 In one embodiment of the present application, a modular vertical-axis wind turbine generator suitable for a communication tower includes a single-tube tower 1 and a vertical-axis wind turbine 4. The vertical-axis wind turbine 4 and the single-tube tower 1 are connected by a connecting assembly. The connecting assembly includes a plug-in mechanism and an inner buckle mechanism. The plug-in mechanism is connected to the axis of the lower end of the vertical-axis wind turbine 4, and the inner buckle mechanism is arranged on the inner side of the upper end of the single-tube tower 1. A first flange 2 is provided on the outer ring surface of the upper end of the single-tube tower 1 outside the inner buckle mechanism, and a second flange 3 is provided on the outside of the plug-in mechanism. The first flange 2 and the second flange 3 are connected to each other to fix the single-tube tower 1 and the vertical axis wind turbine 4.

[0024] Furthermore, a plurality of flange connection holes 10 for positioning and fixing are correspondingly opened inside the first flange 2 and the second flange 3 .

[0025] This embodiment is achieved as follows: by providing a plug-in mechanism at the lower end of the vertical-axis wind turbine 4 and connecting it with the inner buckle mechanism provided at the top of the single-tube tower 1, firstly, auxiliary positioning during assembly and plugging is achieved, thereby improving installation efficiency; secondly, during the assembly and plugging process, the inner buckle mechanism can automatically lock and position, thereby ensuring a stable and rapid connection between the vertical-axis wind turbine 4 and the single-tube tower 1, thereby ensuring stability during subsequent use, and without requiring modification to the tower body, providing a modular structure, so that it can be applied to most vertical-axis wind turbines 4 and single-tube towers 1, thereby significantly reducing installation costs; Furthermore, the vertical axis wind turbine 4 and the single tube tower 1 are subsequently fixed again by the secondary fixing of the first flange 2 and the second flange 3, thereby ensuring the stability of the connection between the vertical axis wind turbine 4 and the single tube tower 1; In addition, the connection component is divided into two parts: an inner buckle mechanism and a plug-in mechanism. The two parts are respectively arranged on the vertical axis wind turbine 4 and the single tube tower 1. It can be set as a modular product and applied to vertical axis wind turbines 4 and single tube towers 1 of different specifications and sizes, thereby reducing installation costs.

[0026] Specifically, it is inserted into the inner buckle mechanism through the plug-in mechanism. During the plug-in process, this is a one-time connection and fixation. After the plug-in mechanism completely enters the inner buckle mechanism, the inner buckle mechanism will be fastened and fixed to the outer side of the plug-in mechanism for a second time, and the overall connection will be more stable.

[0027] It should be noted that the vertical axis wind turbine 4 and the single tube tower 1 are conventional technical means known to those skilled in the art at this stage and are existing technologies, so they will not be described in detail here. The specific power or size of the vertical axis wind turbine 4 and the single tube tower 1 will be adjusted by the actual implementation and will not be limited here.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As a preferred embodiment of the present application, the plug-in mechanism specifically includes a support tube 5 connected to the axis center of the lower end of the vertical axis wind turbine 4 at one end, a plurality of connection grooves 19 evenly opened at the other end of the support tube 5, and an inner rod 22 plugged into the interior of the support tube 5. A second connection shaft 18 is provided inside a single connection groove 19, and a trigger block 20 is connected to the outer side of the second connection shaft 18; The support tube 5 is used to connect the vertical axis wind turbine 4 with the inner buckle mechanism. The outer side of the support tube 5 is also provided with an inner buckle groove 21, which is used to connect with the inner buckle mechanism. The inner side of the support tube 5 is provided with an extrusion groove 17 between the two connecting grooves 19. The extrusion groove 17 is opened downwardly from the inner side of the support tube 5 and extends to the inner sides of the two adjacent trigger blocks 20. The lower end surface of the inner rod 22 is also connected to a trigger part, which is pushed down by the inner rod 22 and contacts the extrusion groove 17. The trigger part contacts the extrusion groove 17 to squeeze the trigger block 20 outward. During the outward extrusion process of the trigger block 20, the inner buckle mechanism is driven to connect with the inner buckle groove 21.

[0029] Furthermore, the trigger part includes a sleeve 23 evenly distributed on the end surface of the inner rod 22, an extrusion spring 24 one end of which is connected to the bottom of a single sleeve 23, and an extrusion column 26 slidably connected to the inside of the sleeve 23. The end surface of the extrusion column 26 located inside the sleeve 23 is connected to the other end of the extrusion spring 24, and the end surface of the extrusion column 26 located outside the sleeve 23 is connected to the extrusion block 25, and the extrusion block 25 is in contact with the extrusion groove 17 and the trigger block 20.

[0030] Furthermore, the number of the sleeves 23 matches the number of the extrusion grooves 17 .

[0031] Furthermore, a toggle slot 7 is formed on the outer side of the support tube 5 above the second flange 3, and a toggle rod 6 is connected to the outer side of the inner rod 22 at a position corresponding to the toggle slot 7, and the toggle rod 6 extends to the outside of the toggle slot 7; The inner rod 22 and the support tube 5 are provided with a fixing hole 9 below the toggle slot 7 , and a fixing rod 8 for fixing the inner rod 22 and the support tube 5 is inserted into the fixing hole 9 .

[0032] This embodiment is implemented as follows: wherein, the plug-in mechanism is used by the support tube 5 in conjunction with the second connecting shaft 18 provided at its lower end. The second connecting shaft 18 is rotated on the outside to connect the trigger block 20, so that the trigger block 20 can be flipped outward. How to flip the trigger block 20 is to drive the trigger part downward by the inner rod 22 inside the support tube 5, and push the trigger part into the inside of the extrusion groove 17. The extrusion groove 17 itself is inclined outward, and the trigger part itself can also extend outward, so as to ensure that the trigger block 20 can be pushed outward stably, ensuring that the subsequent trigger block 20 can stably trigger the inner buckle mechanism. The trigger part of the present application is used in conjunction with the extrusion spring 24 through the sleeve 23 to push out the extrusion column 26. When the extrusion column 26 is pushed outward, the extrusion block 25 will be squeezed into the extrusion groove 17. It should be noted that the installation position of the trigger part is between the gaps of the connecting grooves 19 to ensure that a single trigger part can enter the extrusion groove 17 between the two trigger blocks 20, thereby ensuring that a single trigger part stably triggers the two trigger blocks 20.

[0033] As for how to ensure that the trigger part moves downward stably, the present application pushes down the inner rod 22 so that the inner rod 22 drives the trigger part to move downward inside the support tube 5. In order to facilitate the pushing down of the inner rod 22, a toggle groove 7 is opened on the side of the support tube 5. The outer side of the inner rod 22 is also connected to the toggle rod 6. The toggle rod 6 extends to the outside of the toggle groove 7, pushing the toggle rod 6 to drive the inner rod 22 to move downward. After determining that the trigger part has entered the inner buckle mechanism, it has reached the fixed position. At this time, it is connected to the fixing hole 9 through the fixing rod 8 to achieve fixation.

[0034] See also Figure 1 and Figure 5 As a preferred embodiment of the present application, the inner buckle mechanism specifically includes an inserting cavity 12 opened inside the top of the single-tube tower 1, an extrusion cavity 11 opened inside the inserting cavity 12, and a locking portion installed at the cornice where the extrusion cavity 11 and the inserting cavity 12 meet; The plug-in mechanism is connected to the plug-in cavity 12 and extends into the extrusion cavity 11 . When the plug-in mechanism enters the extrusion cavity 11 , it squeezes the lower end of the locking portion and connects the upper end of the locking portion to the inner buckle groove 21 .

[0035] Furthermore, the locking portion specifically includes a plurality of storage chambers 13 opened inside the plug-in chamber 12 and the extrusion chamber 11, a first connecting shaft 15 installed in the middle position of a single storage chamber 13, and a pressure rod 16 connected to the outside of the first connecting shaft 15. The pressure rod 16 is located at the upper end inside the storage chamber 13 and is equipped with an inner buckle pin 14, and when the plug-in mechanism enters the extrusion chamber 11, it squeezes the lower end of the pressure rod 16 to connect the inner buckle pin 14 with the inner buckle groove 21.

[0036] Furthermore, the number and positions of the receiving cavities 13 correspond to the number and positions of the inner buckle grooves 21 .

[0037] Furthermore, an elastic retraction member is provided between the outer side of one end of the pressure rod 16 close to the inner buckle pin 14 and the receiving cavity 13 .

[0038] This embodiment is implemented as follows: As mentioned above, the inner buckle mechanism is used in conjunction with the plug-in mechanism. The above has explained how the plug-in mechanism enters the inner buckle mechanism to achieve positioning. The inner buckle mechanism is specifically formed by the combination of the plug-in cavity 12 and the extrusion cavity 11. The side cross-sectional shape of the extrusion cavity 11 is an inverted trapezoid, the purpose of which is to adapt to the shape of the trigger portion extending outward. When the trigger portion drives the trigger block 20 to push outward, it will squeeze the locking portion in the inner buckle mechanism. The lower end of the locking portion is squeezed, and its upper end will be buckled inward, thus connecting with the inner buckle groove 21 provided on the outside of the plug-in mechanism, thereby achieving locking; Among them, the locking part is specifically composed of a receiving chamber 13 set inside the plug-in chamber 12 and the extrusion chamber 11, and a first connecting shaft 15 set in the middle section of the receiving chamber 13. A pressure rod 16 is set on the outside of the first connecting shaft 15. The lower end of the pressure rod 16 is inside the extrusion chamber 11. After the trigger block 20 enters the extrusion groove 17, it is pushed toward the periphery of the extrusion chamber 11, thereby pushing the lower end of the pressure rod 16. At this time, the upper end of the pressure rod 16 will be ejected. During the ejection process, the inner buckle pin 14 at its upper end enters the inner buckle groove 21, thereby achieving self-locking.

[0039] It should be noted that the number of storage cavities 13, that is, the number and position of the locking parts, corresponds to the number and position of the inner buckle grooves 21. This ensures that the inner buckle pins 14 can be evenly and stably buckled in the inner buckle grooves 21 on the outside of the support tube 5, ensuring the stability of the support tube 5 and preventing deviation.

[0040] Moreover, in the subsequent disassembly process, it is more convenient to set an elastic pullback member on the outer side of the end of the pressure rod 16 close to the inner buckle pin 14, and pull the upper end of the pressure rod 16 back to make the inner buckle pin 14 disengage from the inner buckle groove 21. Because it is necessary to release the connection between the locking part and the plug-in mechanism during disassembly, the inner rod 22 is driven upward by the upper lifting rod 6, and the extrusion spring 24 is contracted to pull the extrusion column 26 back, so that the trigger block 20 is disengaged from the extrusion block 25, so that the trigger block 20 is rotated and falls back to a state perpendicular to the lower end of the support tube 5 by adhering to the second connecting shaft 18. At this time, the pressure rod 16 The inner buckle pin 14 at the upper end is loose, but is still inside the inner buckle groove 21, so an elastic pullback member needs to be provided to pull the upper end of the pressure rod 16 back toward the inside of the storage chamber 13 to quickly release the connection. The advantage of such a setting is that it can also ensure that when not connected, the upper end of the pressure rod 16 can always be pulled back toward the inside of the storage chamber 13, ensuring that the inner buckle pin 14 will not be blocked during the connection process. For the elastic pullback member, a pullback spring or other elastic materials can be used to ensure that the upper end of the pressure rod 16 can be pulled back toward the inside of the storage chamber 13. The specific selection can be made according to the actual usage.

[0041] In summary, the present invention sets a vertical axis wind turbine 4, a single-tube tower 1 and a connecting assembly, and sets a plug-in mechanism at the lower end of the vertical axis wind turbine 4 and connects it with the inner buckle mechanism set at the top of the single-tube tower 1. First, auxiliary positioning during assembly and plugging is achieved, and the installation efficiency is improved. Secondly, during the assembly and plugging process, the inner buckle mechanism can realize automatic locking and positioning, ensuring a stable and fast connection between the vertical axis wind turbine 4 and the single-tube tower 1, ensuring stability during subsequent use, and there is no need to improve the tower body. It is set as a modular structure, so that it can be applied to most vertical axis wind turbines 4 and single-tube towers 1, which significantly reduces the installation cost.

[0042] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventive means, they shall fall within the scope of protection of the present invention.

[0043] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
