Description

Technical Field

[0001] This invention relates to the field of communication tower technology, and more specifically, to a modular vertical axis wind power generation device suitable for communication towers. Background Technology

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

[0003] Traditional communication towers typically employ a single-tube tower structure, resulting in underutilization of their top space. Vertical axis wind turbines (VAWTs), with their advantages of low-wind-speed start-up, strong wind direction adaptability, and low noise, are gradually becoming the preferred solution for communication tower power supply systems. However, the following key issues still exist in existing technologies:

[0004] Vertical axis wind turbines are often connected to communication towers by flange bolts or welding. However, communication towers are subjected to complex stresses such as wind loads and vibrations over a long period of time. Traditional connecting parts are prone to loosening due to fatigue or vibration, which may even lead to structural instability.

[0005] Existing connection devices lack self-locking functionality, requiring regular manual inspection and bolt tightening. This significantly increases maintenance difficulty and cost, especially in remote or high-altitude environments.

[0006] Traditional installation methods require customized modifications to communication towers, making it impossible to quickly disassemble and modularly replace wind power generation devices, thus limiting the equipment's versatility and maintainability.

[0007] To improve power generation efficiency, the size or weight of the wind turbine needs to be increased. However, traditional connection methods are difficult to balance power generation performance with the load-bearing capacity of the communication tower structure, which may lead to stress concentration or fatigue damage to the tower.

[0008] In recent years, the modular design concept has been widely used in the field of communication equipment, but existing technologies have not yet solved the problem of modular integration between vertical axis wind turbines and communication towers, especially lacking a connection device that is self-locking, accurately positioned, and adaptable to complex working conditions.

[0009] 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. Summary of the Invention

[0010] The purpose of this invention is to provide a modular vertical axis wind power generation device suitable for communication towers, so as to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a modular vertical axis wind power generation device suitable for communication towers, comprising a single-tube tower and a vertical axis wind turbine, wherein the vertical axis wind turbine and the single-tube tower are spliced ​​together by a connecting component, the connecting component comprising a plug-in mechanism and an inner fastening mechanism, the plug-in mechanism being connected to the lower end of the shaft of the vertical axis wind turbine, and the inner fastening mechanism being disposed on the inner side of the upper end of the single-tube tower;

[0012] The upper outer ring of the monotube tower is provided with a first flange located outside the inner buckling mechanism, and a second flange is provided outside the plugging mechanism. The first flange and the second flange are connected to each other to fix the monotube tower and the vertical axis wind turbine.

[0013] A further technical solution of this application: The plug-in mechanism specifically includes a support cylinder with one end connected to the lower shaft of the vertical axis wind turbine, a plurality of connecting slots evenly opened at the other end of the support cylinder, and an inner rod inserted inside the support cylinder. A second connecting shaft is provided inside a single connecting slot, and a trigger block is connected to the outside of the second connecting shaft.

[0014] The support cylinder is used for the vertical axis wind turbine to be inserted into the inner buckling mechanism. The outer side of the support cylinder is also provided with an inner buckling groove, which is used to connect with the inner buckling mechanism. The inner side of the support cylinder is provided with a pressing groove between the two connecting grooves. The pressing groove is opened downward from the inner side of the support cylinder and extends to the inner side of the two adjacent trigger blocks.

[0015] The lower end face of the inner rod is also connected to a trigger part. The trigger part is pushed down by the inner rod and contacts the extrusion groove. The contact between the trigger part and the extrusion groove causes the trigger block to be extruded outward. During the outward extrusion of the trigger block, the inner buckling mechanism is connected to the inner buckling groove.

[0016] A further technical solution of this application: The triggering part includes sleeves evenly distributed on the end face of the inner rod, a compression spring connected at one end to the bottom of the single sleeve, and a compression column slidably connected inside the sleeve. The end face of the compression column inside the sleeve is connected to the other end of the compression spring, and the end face of the compression column outside the sleeve is connected to a compression block. The compression block is in contact with the compression groove and the trigger block.

[0017] A further technical solution of this application is that the number of sleeves matches the number of extrusion grooves.

[0018] A further technical solution of this application: the outer side of the support cylinder is provided with a through groove above the second flange, and a lever is connected to the outer side of the inner rod corresponding to the position of the through groove, and the lever extends to the outside of the through groove.

[0019] The inner rod and the support cylinder are provided with a fixing hole below the actuation groove, and a fixing rod for fixing the inner rod and the support cylinder is inserted into the fixing hole.

[0020] A further technical solution of this application: The inner buckling mechanism specifically includes an insertion cavity opened inside the top of the single-tube tower, a squeezing cavity opened inside the insertion cavity, and a locking part installed at the junction of the squeezing cavity and the insertion cavity.

[0021] The insertion mechanism is connected to the insertion cavity and extends into the extrusion cavity. When the insertion mechanism enters the extrusion cavity, it extrudes the lower end of the locking part and connects the upper end of the locking part to the inner groove.

[0022] A further technical solution of this application: The locking part specifically includes a plurality of storage cavities opened inside the insertion cavity and the compression cavity, a first connecting shaft installed in the middle section of a single storage cavity, and a pressure rod connected to the outside of the first connecting shaft. The upper end of the pressure rod located inside the storage cavity is equipped with an inner buckling pin, and when the insertion mechanism enters the compression cavity, it squeezes the lower end of the pressure rod, and the inner buckling pin is connected to the inner buckling groove.

[0023] A further technical solution of this application: the first flange and the second flange have corresponding flange connection holes for positioning and fixing.

[0024] A further technical solution of this application: an elastic pull-back member is provided between the outer side of the end of the pressure rod near the inner buckle pin and the storage cavity.

[0025] Compared with the prior art, the technical solution provided by this invention has the following advantages:

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0037] Please see Figures 1 to 7 In one embodiment of this application, a modular vertical axis wind power generation device suitable for communication towers 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 spliced ​​together by a connecting component. The connecting component includes a plug-in mechanism and an inner fastening mechanism. The plug-in mechanism is connected to the lower shaft of the vertical axis wind turbine 4, and the inner fastening mechanism is disposed on the inner side of the upper end of the single-tube tower 1.

[0038] A first flange 2 is provided on the outer ring surface of the upper end of the single-tube tower 1, located outside the inner buckling mechanism, and a second flange 3 is provided on the outer side 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.

[0039] Furthermore, the first flange 2 and the second flange 3 have corresponding flange connection holes 10 for positioning and fixing.

[0040] This embodiment is implemented as follows: by connecting the plug-in mechanism at the lower end of the vertical axis wind turbine 4 to the internal fastening mechanism at the top of the monotube tower 1, auxiliary positioning is first achieved during assembly and plugging, improving installation efficiency. Secondly, during the assembly and plugging process, the internal fastening mechanism can automatically lock and position, ensuring a stable and rapid connection between the vertical axis wind turbine 4 and the monotube tower 1, ensuring stability during subsequent use. Furthermore, no modifications to the tower body are required, as the modular structure allows it to be applied to most vertical axis wind turbines 4 and monotube towers 1, significantly reducing installation costs.

[0041] Furthermore, the vertical axis wind turbine 4 and the monotube tower 1 are further secured by the second fixing of the first flange 2 and the second flange 3, thus ensuring the stability of the connection between the vertical axis wind turbine 4 and the monotube tower 1.

[0042] Furthermore, the connection component is divided into two parts: an internal buckling mechanism and a plug-in mechanism. These two parts are respectively set on the vertical axis wind turbine 4 and the monotube tower 1. It can be set as a modular product and applied to vertical axis wind turbines 4 and monotube towers 1 of different specifications and sizes, thereby reducing installation costs.

[0043] Specifically, the insertion mechanism is inserted into the inner locking mechanism. During the insertion process, this is the first connection and fixation. After the insertion mechanism is fully inserted into the inner locking mechanism, the inner locking mechanism will then be locked and fixed to the outside of the insertion mechanism a second time, making the overall connection more stable.

[0044] It should be noted that the vertical axis wind turbine 4 and the monotube tower 1 are conventional technical means known to those skilled in the art at this stage and are existing technologies. Therefore, they will not be described in detail here. The specific power or size of the vertical axis wind turbine 4 and the monotube tower 1 used can be adjusted by the implementer and is not restricted here.

[0045] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As a preferred embodiment of this application, the plug-in mechanism specifically includes a support cylinder 5 connected at one end to the lower shaft of the vertical axis wind turbine 4, a plurality of connecting slots 19 evenly opened at the other end of the support cylinder 5, and an inner rod 22 inserted inside the support cylinder 5. A second connecting shaft 18 is provided inside each connecting slot 19, and a trigger block 20 is connected to the outside of the second connecting shaft 18.

[0046] The support cylinder 5 is used to connect the vertical axis wind turbine 4 to the inner buckling mechanism. The outer side of the support cylinder 5 is also provided with an inner buckling groove 21, which is used to connect with the inner buckling mechanism. The inner side of the support cylinder 5 is provided with a pressing groove 17 between the gaps of the two connecting grooves 19. The pressing groove 17 is opened downward from the inner side of the support cylinder 5 and extends to the inner side of the two adjacent trigger blocks 20.

[0047] The lower end face of the inner rod 22 is also connected to a trigger part. The trigger part is pushed down by the inner rod 22 and contacts the extrusion groove 17. The contact between the trigger part and the extrusion groove 17 extrudes the trigger block 20 outward. During the outward extrusion of the trigger block 20, the inner buckling mechanism is connected to the inner buckling groove 21.

[0048] Furthermore, the triggering part includes sleeves 23 evenly distributed on the end face of the inner rod 22, a compression spring 24 connected at one end to the bottom of the inner sleeve 23, and a compression column 26 slidably connected inside the sleeve 23. The end face of the compression column 26 inside the sleeve 23 is connected to the other end of the compression spring 24, and the end face of the compression column 26 outside the sleeve 23 is connected to a compression block 25. The compression block 25 is in contact with the compression groove 17 and the triggering block 20.

[0049] Furthermore, the number of sleeves 23 matches the number of extrusion grooves 17.

[0050] Furthermore, the outer side of the support cylinder 5 is provided with a through groove 7 above the second flange 3, and the outer side of the inner rod 22 is connected to a lever 6 corresponding to the position of the through groove 7, and the lever 6 extends to the outside of the through groove 7.

[0051] The inner rod 22 and the support cylinder 5 are provided with a fixing hole 9 below the actuation groove 7, and a fixing rod 8 for fixing the inner rod 22 and the support cylinder 5 is inserted into the fixing hole 9.

[0052] This embodiment is implemented as follows: The insertion mechanism is used by the support cylinder 5 in conjunction with the second connecting shaft 18 set at its lower end. The trigger block 20 is rotatably connected to the outside of the second connecting shaft 18, so that the trigger block 20 can be flipped outward. The flipping of the trigger block 20 is achieved by the inner rod 22 inside the support cylinder 5 driving the trigger part to move downward, pushing the trigger part into the squeezing groove 17. The squeezing groove 17 itself is inclined outward, and the trigger part itself can also extend outward. This ensures that the trigger block 20 can be stably pushed outward, ensuring that the trigger block 20 can stably trigger the inner buckling mechanism in the future.

[0053] The triggering part of this application is used in conjunction with the compression spring 24 through the sleeve 23 to push out the compression column 26. When the compression column 26 is pushed outward, it will squeeze the compression block 25 into the compression groove 17. It should be noted that the installation position of the triggering part is between the gaps of the connecting groove 19, so as to ensure that a single triggering part can enter the compression groove 17 between the two triggering blocks 20, thus ensuring that a single triggering part stably triggers the two triggering blocks 20.

[0054] To ensure the stable downward movement of the triggering part, this application uses the downward push of the inner rod 22 to drive the triggering part to move downward inside the support cylinder 5. To facilitate the downward push of the inner rod 22, a toggle groove 7 is provided on the side of the support cylinder 5. A lever 6 is also connected to the outer side of the inner rod 22. The lever 6 extends to the outside of the toggle groove 7. Pushing the lever 6 drives the inner rod 22 to move downward. After confirming that the triggering part has entered the inner buckling mechanism, it reaches the fixed position. At this time, it is fixed by connecting the fixing rod 8 to the fixing hole 9.

[0055] Please see Figure 1 and Figure 5 As a preferred embodiment of this application, the inner buckling mechanism specifically includes an insertion cavity 12 opened inside the top of the single tube tower 1, a compression cavity 11 opened inside the insertion cavity 12, and a locking part installed at the junction of the compression cavity 11 and the insertion cavity 12.

[0056] The insertion mechanism is connected to the insertion cavity 12 and extends into the compression cavity 11. When the insertion mechanism enters the compression cavity 11, it compresses the lower end of the locking part and connects the upper end of the locking part to the inner groove 21.

[0057] Furthermore, the locking part specifically includes a plurality of storage cavities 13 opened inside the insertion cavity 12 and the compression cavity 11, a first connecting shaft 15 installed in the middle section of a single storage cavity 13, and a pressure rod 16 connected to the outside of the first connecting shaft 15. The upper end of the pressure rod 16 located inside the storage cavity 13 is equipped with an inner buckle pin 14, and when the insertion mechanism enters the compression cavity 11, it squeezes the lower end of the pressure rod 16, connecting the inner buckle pin 14 with the inner buckle groove 21.

[0058] Furthermore, the number and position of the receiving cavities 13 correspond to the number and position of the inner buckle grooves 21.

[0059] Furthermore, an elastic pull-back member is provided between the outer side of the end of the pressure rod 16 near the inner buckle pin 14 and the storage cavity 13.

[0060] This embodiment is implemented as follows: As mentioned above, the inner locking mechanism is used in conjunction with the insertion mechanism. It has been explained above how the insertion mechanism enters the inner locking mechanism to achieve positioning. Specifically, the inner locking mechanism is formed by the combination of the insertion cavity 12 and the compression cavity 11. The side view cross-sectional shape of the compression cavity 11 is an inverted trapezoid, which is intended to adapt to the shape of the trigger part extending outward. When the trigger part drives the trigger block 20 to push outward, it will squeeze the locking part in the inner locking mechanism. The lower end of the locking part is squeezed, and its upper end will be locked inward, thus connecting with the inner locking groove 21 provided on the outside of the insertion mechanism, thereby achieving locking.

[0061] Specifically, the locking part consists of a receiving cavity 13 set inside the insertion cavity 12 and the compression cavity 11, and a first connecting shaft 15 set in the middle section inside the receiving cavity 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 compression cavity 11. After the trigger block 20 enters the compression groove 17, it is pushed towards the outside of the compression cavity 11. This pushes the lower end of the pressure rod 16. At this time, the upper end of the pressure rod 16 will be pushed out. During the pushing out process, the inner buckle pin 14 at its upper end enters the inner buckle groove 21, thus realizing self-locking.

[0062] It should be noted that the number and position of the storage cavities 13, which is also the number and position of the locking parts, correspond to the number and position of the inner buckle grooves 21. This ensures that the inner buckle pins 14 can be evenly and stably fastened around the inner buckle grooves 21 on the outside of the support cylinder 5, ensuring the stability of the support cylinder 5 and preventing any deviation.

[0063] Furthermore, it facilitates subsequent disassembly. An elastic pull-back component can be installed on the outer side of the end of the pressure rod 16 near the inner buckle pin 14 to pull back the upper end of the pressure rod 16, causing the inner buckle pin 14 to disengage from the inner buckle groove 21. Since the connection between the locking part and the insertion mechanism needs to be released during disassembly, this is achieved by lifting the lever 6, which moves the inner rod 22 upwards, causing the compression spring 24 to contract and pull back the compression column 26. This allows the trigger block 20 to disengage from the compression block 25, enabling the trigger block 20 to rotate and fall back to a state perpendicular to the lower end of the support cylinder 5, attached to the second connecting shaft 18. At this point, the pressure rod 16... The upper inner pin 14 is loose, but it is still inside the inner groove 21. Therefore, an elastic pull-back component is needed to pull the upper end of the pressure rod 16 back into the storage cavity 13 to quickly disconnect the connection. The advantage of this design is that when not connected, the upper end of the pressure rod 16 can always be pulled back into the storage cavity 13, ensuring that the inner pin 14 will not obstruct the connection process. The elastic pull-back component can be a pull-back spring or other elastic material, which can be used to ensure that the upper end of the pressure rod 16 can be pulled back into the storage cavity 13. The specific choice can be made according to the actual use.

[0064] In summary, this invention, by setting up a vertical axis wind turbine 4, a monotube tower 1, and a connecting assembly, and by connecting the lower end of the vertical axis wind turbine 4 with the inner fastening mechanism at the top of the monotube tower 1, firstly achieves auxiliary positioning during assembly and connection, improving installation efficiency. Secondly, during the assembly and connection process, the inner fastening mechanism can automatically lock and position, ensuring a stable and rapid connection between the vertical axis wind turbine 4 and the monotube tower 1, ensuring stability during subsequent use. Furthermore, it eliminates the need for tower body modifications, and its modular structure allows it to be applied to most vertical axis wind turbines 4 and monotube towers 1, significantly reducing installation costs.

[0065] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0066] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
