Description

Technical Field

[0001] This utility model relates to the technical field of vertical axis wind power generation equipment, and in particular to a vertical axis wind power generation support platform. Background Technology

[0002] Vertical axis wind turbines are a type of wind power generation technology with a unique structure and operating principle. Unlike traditional horizontal axis wind turbines, the shaft of a vertical axis wind turbine is perpendicular to the ground. When the wind drives its rotation, it can harvest energy from winds in all directions. However, the winds from all directions also subject the rotor to frequent load changes, which may lead to accelerated wear on the platform and generator. The structure of a vertical axis wind turbine may encounter fatigue problems during long-term operation, reducing its service life.

[0003] CN216714604U discloses a vertical axis wind power generation support platform, including a support platform, a braking device, a locking device, a limiting bushing, a cover plate, a wind turbine main shaft, a dustproof ring, a self-aligning roller bearing, a gear speed-increasing mechanism, a power generation device, a single-row tapered roller bearing, a main shaft support, and a platform base. The main shaft support is fixedly installed at the center of the bottom of the support platform. This vertical axis wind power generation support platform, by shortening the length of the wind turbine main shaft at the center inside the support platform, enables the wind turbine to run smoothly and overcomes the defects of poor stability of the wind turbine system and excessive wind turbine sway. Installing an auxiliary support mechanism on the outer surface of the support platform can improve the stability of the unit, improve the stress condition of the single crossbeam, overcome wind turbine sway, and make the unit more stable. Installing a braking device on the edge of the limiting bushing and a locking device on the center edge of the top surface of the support platform can make the braking effect safer and more reliable.

[0004] Although this device reduces the oscillation amplitude of the main shaft by shortening its length, making the wind turbine more stable, the rotor will experience frequent load changes due to the constantly changing wind direction. The shortened main shaft causes the bearings inside to be subjected to greater eccentric forces, accelerating internal wear and reducing service life. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a vertical axis wind power generation support platform.

[0006] This utility model is achieved using the following technical solution: a vertical axis wind power generation support platform, including a base plate, a support mechanism and a rotating mechanism on the top of the base plate, a support extension platform inside the support mechanism, a planetary gear on the top of the support extension platform, a driven gear at the bottom of the support extension platform, a generator fixedly connected to the top of the base plate, a generator gear fixedly connected to the top of the generator, and a braking device fixedly connected to the top of the base plate;

[0007] The support mechanism includes a support barrel, a partition plate is fixedly connected to the surface of the support barrel, a support frame is fixedly connected to the surface of the support barrel, and a limit graphite ring is fixedly connected to one end of the support frame.

[0008] The above technical solution divides the interior of the device into several small spaces using partition plates, separating the three generators and the internal shaft. This prevents the failure of one generator from affecting the normal operation of the remaining generators and shaft. At the same time, the partition plates act as reinforcing ribs between the support barrel and the base plate, improving the structural stability of the device. The support frame supports the limiting graphite ring to limit the swing of the shaft, reducing the bias force on the shaft. Meanwhile, the graphite in the limiting graphite ring is an excellent lubricating and wear-resistant material that does not affect energy transfer, thus extending the service life of the device.

[0009] As a further improvement to the above solution, the bottom of the support barrel is fixedly connected to the top of the base plate, the bottom of the partition plate is fixedly connected to the top of the base plate, and the inner wall of the support barrel is fixedly connected to one end of the support extension platform.

[0010] As a further improvement to the above solution, the rotating mechanism includes a vertical shaft, a bottom bearing fixedly connected to the bottom of the vertical shaft, a top bearing fixedly connected to the top of the vertical shaft, a rotating shaft provided on the outside of the vertical shaft, and a stellar gear fixedly connected to the surface of the rotating shaft.

[0011] As a further improvement to the above solution, the bottom of the vertical shaft is fixedly connected to the top of the base plate, the surface of the bottom bearing is fixedly connected to the bottom of the inner wall of the rotating shaft, and the surface of the top bearing is fixedly connected to the top of the inner wall of the rotating shaft.

[0012] The above technical solution ensures that the vertical shaft does not directly contact the rotating shaft by using bottom and top bearings, thereby reducing the heat generated during shaft rotation and ensuring normal operation of the device.

[0013] As a further improvement to the above scheme, the sun gear meshes with the planetary gear, and a fixing rod is fixedly connected to the inner wall of the planetary gear.

[0014] Through the above technical solution, the power transmission between the stellar gear and the planetary gears is achieved by preventing the generator gear from directly meshing with the stellar gear. By using a multi-gear design and a gradual transmission method, the load of each gear set is distributed, avoiding excessive pressure on a single gear, thereby reducing tooth surface wear and extending the service life of the device.

[0015] As a further improvement to the above solution, the surface of the fixing rod is rotatably connected to the inner wall of the support extension platform, and the lower end of the fixing rod passes through the support extension platform and is fixedly connected to the inner wall of the driven gear.

[0016] As a further improvement to the above solution, the inner wall of the limiting graphite ring is rotatably connected to the surface of the rotating shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model incorporates a support mechanism, specifically a partition plate that divides the interior of the device into several small spaces, separating the three generators and the internal shaft. This prevents a failure in one generator from affecting the normal operation of the remaining generators and shaft. Simultaneously, the partition plate acts as a reinforcing rib between the support barrel and the base plate, improving the structural stability of the device. A support frame supports a limiting graphite ring to limit the shaft's sway, reducing the bias force on the shaft. Furthermore, the graphite in the limiting graphite ring, being an excellent lubricating and wear-resistant material, does not affect energy transfer, extending the device's service life.

[0019] This invention features a rotating mechanism that uses bottom and top bearings to prevent the vertical shaft from directly contacting the rotating shaft, reducing the heat generated during shaft rotation and ensuring normal device operation. Power transmission via a sun gear and planetary gears prevents the generator gear from directly meshing with the sun gear. The design of multiple gear sets, using a gradual transmission method, distributes the load across each gear set, preventing excessive pressure on individual gears, thus reducing tooth wear and extending the device's lifespan.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment provides a vertical axis wind power generation support platform, comprising a base plate 1, a support mechanism 2 and a rotation mechanism 3 on the top of the base plate 1, a support extension platform 4 inside the support mechanism 2, a planetary gear 5 on the top of the support extension platform 4, a driven gear 6 at the bottom of the support extension platform 4, a generator 7 fixedly connected to the top of the base plate 1, a generator gear 8 fixedly connected to the top of the generator 7, and a braking device 9 fixedly connected to the top of the base plate 1.

[0030] The support mechanism 2 includes a support barrel 201. A partition plate 202 is fixedly connected to the surface of the support barrel 201. The partition plate 202 divides the interior of the device into several small spaces, separating the three sets of generators 7 and the internal shaft. This prevents the failure of one set of generators 7 from affecting the normal operation of the other generators 7 and the shaft. At the same time, the partition plate 202 serves as a reinforcing rib structure between the support barrel 201 and the base plate 1, improving the structural stability of the device. A support frame 203 is fixedly connected to the surface of the support barrel 201. A limiting graphite ring 204 is fixedly connected to one end of the support frame 203. The limiting graphite ring 204 supported by the support frame 203 provides limiting support for the swing of the shaft, reducing the bias force on the shaft. Meanwhile, the graphite in the limiting graphite ring 204 is an excellent lubricating and wear-resistant material that does not affect energy transmission, extending the service life of the device.

[0031] The bottom of the support barrel 201 is fixedly connected to the top of the base plate 1, the bottom of the partition plate 202 is fixedly connected to the top of the base plate 1, and the inner wall of the support barrel 201 is fixedly connected to one end of the support extension platform 4.

[0032] The rotating mechanism 3 includes a vertical shaft 301, a bottom bearing 302 fixedly connected to the bottom of the vertical shaft 301, a top bearing 303 fixedly connected to the top of the vertical shaft 301, and a rotating shaft 304 disposed on the outside of the vertical shaft 301. A stellar gear 305 is fixedly connected to the surface of the rotating shaft 304. The bottom bearing 302 and the top bearing 303 prevent the vertical shaft from directly contacting the rotating shaft 304, thereby reducing the heat generated when the shaft rotates and ensuring the normal operation of the device.

[0033] The bottom of the vertical shaft 301 is fixedly connected to the top of the base plate 1, the surface of the bottom bearing 302 is fixedly connected to the bottom of the inner wall of the rotating shaft 304, and the surface of the top bearing 303 is fixedly connected to the top of the inner wall of the rotating shaft 304.

[0034] The sun gear 305 meshes with the planet gear 5. A fixed rod is fixedly connected to the inner wall of the planet gear 5. Through the power transmission between the sun gear 305 and the planet gear 5, the generator gear 8 does not directly mesh with the sun gear 305. Through the design of multiple sets of gears and the gradual transmission method, the load of each set of gears is distributed, avoiding excessive pressure on a single gear, thereby reducing tooth surface wear and extending the service life of the device.

[0035] The surface of the fixed rod is rotatably connected to the inner wall of the support extension platform 4, and the lower end of the fixed rod passes through the support extension platform 4 and is fixedly connected to the inner wall of the driven gear 6.

[0036] The inner wall of the limiting graphite ring 204 is rotatably connected to the surface of the rotating shaft 304.

[0037] The implementation principle of a vertical axis wind power generation support platform in this application embodiment is as follows: During use, wind power causes the blades to rotate. The rotating shaft 304 rotates outside the vertical shaft 301 through the bottom bearing 302 and the top bearing 303. The bottom bearing 302 and the top bearing 303 prevent the vertical shaft 301 from directly contacting the rotating shaft 304, reducing the heat generated during shaft rotation from affecting the normal operation of the device. At the same time, it drives the sun gear 305 to rotate. The planetary gear 5 drives the driven gear 6 to rotate through the sun gear 305. Through the power transmission between the sun gear 305 and the planetary gear 5, the generating gear 8 does not directly mesh with the sun gear 305. Through the design of multiple sets of gears and the gradual transmission method, the load of each set of gears is distributed, avoiding excessive pressure on a single gear. This reduces tooth surface wear. The generator gear 8 rotates to start the generator 7. The partition plate 202 divides the inside of the device into several small spaces, separating the three generators 7 and the internal shaft. This prevents the failure of one generator 7 from affecting the normal operation of the other generators 7 and the shaft. At the same time, the partition plate 202 acts as a reinforcing rib between the support barrel 201 and the base plate 1, improving the structural stability of the device. In strong winds, turbulent air blows the blades, causing the rotating shaft 304 to vibrate and swing. The support frame 203 supports the limiting graphite ring 204 to limit the swing of the shaft, offsetting some of the bias force in advance and reducing the impact on the shaft. Meanwhile, the graphite in the limiting graphite ring 204 is an excellent lubricating and wear-resistant material that does not affect energy transmission and extends the service life of the device.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
