Abstract
Description
Technical Field
[0001] The present invention 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 Art
[0002] Vertical-axis wind turbines (VAWTs) are a type of wind power generation technology with a unique structure and operating principle. Unlike traditional horizontal-axis wind turbines, VAWTs rotate with their shaft perpendicular to the ground. As the wind propels them, they can extract energy from winds in all directions. However, these varying winds also subject the rotor to frequent load changes, potentially increasing wear on the platform and generator. Over time, the VAWT's structure may experience fatigue, reducing its service life.
[0003] Publication number CN216714604U discloses a vertical axis wind power generation support platform, including a support platform, a braking device, a locking device, a limiting shaft sleeve, a cover plate, a wind rotor main shaft, a dust ring, a spherical 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 inner bottom center of the support platform. The vertical axis wind power generation support platform can make the wind rotor run smoothly by shortening the length of the wind rotor main shaft at the inner center of the support platform, and overcome the defects of poor stability of the wind rotor system and excessive swing amplitude of the wind rotor. An auxiliary supporting mechanism is installed on the outer surface of the support platform to improve the stability of the unit, improve the stress condition of the single beam, overcome the swing of the wind rotor, and make the unit more stable. A braking device is installed on the edge of the limiting shaft sleeve, and a locking device is installed on the center edge of the top surface of the support platform to make the braking effect safer and more reliable.
[0004] Although this device reduces the swing amplitude of the main shaft by shortening the length of the wind rotor, making the wind rotor more stable, the rotor will experience frequent load changes due to the constantly changing direction of the wind. The shortened main shaft causes the internal bearings to be subjected to greater deflection force, accelerating internal wear and reducing service life. Summary of the Invention
[0005] In order to solve the above technical problems, the present invention provides a vertical axis wind power generation support platform.
[0006] The present invention is implemented by the following technical solution: a vertical axis wind power generation support platform, comprising a base plate, a support mechanism provided on the top of the base plate, a rotating mechanism provided on the top of the base plate, a support extension platform provided inside the support mechanism, a planetary gear provided on the top of the support extension platform, a driven gear provided on the bottom of the support extension platform, a generator fixedly connected to the top of the base plate, a power generation gear fixedly connected to the top of the generator, and a brake device fixedly connected to the top of the base plate;

[0012] Through the above technical solution, the vertical shaft does not directly contact the rotating shaft through the bottom bearing and the top bearing, thereby reducing the heat generated when the shaft rotates and ensuring normal use of the device.
[0013] As a further improvement of the above solution, the sun gear is meshed with the planetary gears, and the inner wall of the planetary gear is fixedly connected with a fixing rod.
[0014] Through the above technical solution, the power transmission of the sun gear and the planetary gear is used to prevent the generator gear from directly engaging with the sun gear. Through the design of multiple sets of gears and the gradual transmission method, the load of each set of gears is dispersed, preventing a single gear from being subjected to excessive pressure, thereby reducing tooth surface wear and extending the service life of the device.
[0015] As a further improvement of the above solution, the surface of the fixing rod is rotatably connected to the inner wall of the supporting extension platform, and the lower end of the fixing rod passes through the supporting extension platform and is fixedly connected to the inner wall of the driven gear.
[0016] As a further improvement of 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 present invention has the following beneficial effects:
[0018] The present invention provides a support mechanism, specifically, divides the interior of the device into several small spaces through a partition plate, separates the three groups of generators and the internal shaft, and prevents the failure of one group of generators from affecting the normal operation of the remaining generators and the shaft.

At the same time, the graphite of the limiting graphite ring, as an excellent lubricating and wear-resistant material, does not affect energy transmission, thereby extending the service life of the device.

Through the power transmission of the sun gear and the planetary gear, the generator gear does not directly engage with the sun gear. Through the design of multiple sets of gears and the gradual transmission method, the load of each set of gears is dispersed, preventing a single gear from being subjected to excessive pressure, thereby reducing tooth surface wear and extending the service life of the device.

DETAILED DESCRIPTION

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Please combine Figure 1-5 , a vertical axis wind power generation support platform of this embodiment, a base plate 1, a support mechanism 2 is provided on the top of the base plate 1, a rotating mechanism 3 is provided on the top of the base plate 1, a support extension platform 4 is provided inside the support mechanism 2, a planetary gear 5 is provided on the top of the support extension platform 4, a driven gear 6 is provided on the bottom of the support extension platform 4, a generator 7 is fixedly connected to the top of the base plate 1, a power generation gear 8 is fixedly connected to the top of the generator 7, and a brake device 9 is fixedly connected to the top of the base plate 1;
[0030] The support mechanism 2 includes a support barrel 201, and 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 groups of generators 7 and the internal shaft body to prevent the failure of one group of generators 7 from affecting the normal operation of the remaining generators 7 and the shaft body. At the same time, the partition plate 202 serves as a reinforcing rib structure between the support barrel 201 and the bottom plate 1 to improve the structural stability of the device. The surface of the support barrel 201 is fixedly connected to a support frame 203, and one end of the support frame 203 is fixedly connected to a limiting graphite ring 204. The limiting graphite ring 204 is supported by the support frame 203 to limit the swing of the shaft body, thereby reducing the deflection force on the shaft body. At the same time, the graphite of the limiting graphite ring 204, as an excellent lubricating and wear-resistant material, does not affect energy transfer, thereby extending the service life of the device.
[0031] The bottom of the support barrel 201 is fixedly connected to the top of the bottom plate 1 , the bottom of the partition plate 202 is fixedly connected to the top of the bottom 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, the bottom of the vertical shaft 301 is fixedly connected to a bottom bearing 302, the top of the vertical shaft 301 is fixedly connected to a top bearing 303, a rotating shaft 304 is provided on the outside of the vertical shaft 301, and a sun 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 during the rotation of the shaft and ensuring the normal use 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 is meshed with the planetary gear 5. A fixed rod is fixedly connected to the inner wall of the planetary gear 5. The power is transmitted through the sun gear 305 and the planetary gear 5 so that 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 dispersed, preventing a single gear from being subjected to excessive pressure, thereby reducing tooth surface wear and extending the service life of the device.
[0035] The surface of the fixing rod is rotatably connected to the inner wall of the supporting extension platform 4 , and the lower end of the fixing rod passes through the supporting 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 the embodiment of the present application is as follows: when in use, the wind force causes the blades to rotate, and the rotating shaft 304 rotates outside the vertical shaft 301 through the bottom bearing 302 and the top bearing 303. The vertical shaft 301 is prevented from directly contacting the rotating shaft 304 through the bottom bearing 302 and the top bearing 303, thereby reducing the heat generated when the shaft rotates and affecting the normal use of the device. At the same time, it drives the sun gear 305 to rotate, and the planetary gear 5 drives the driven gear 6 to rotate through the sun gear 305. The power transmission through the sun gear 305 and the planetary gear 5 prevents the power generation gear 8 from directly engaging 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 dispersed to prevent a single gear from being subjected to excessive pressure. , thereby reducing tooth surface wear, the power generation gear 8 follows the rotation to enable the generator 7 to start working, and the interior of the device is divided into several small spaces by the partition plate 202, which separates the three groups of generators 7 and the internal shaft to prevent the normal operation of the remaining generators 7 and the shaft from being affected when one group of generators 7 fails. At the same time, the partition plate 202 serves as a reinforcing rib structure between the support barrel 201 and the bottom plate 1 to improve the structural stability of the device. In strong winds, turbulent flow blows the blades to cause 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 part of the deflection force in advance and reducing the impact on the shaft. At the same time, the graphite of the limiting graphite ring 204, as an excellent lubricating and wear-resistant material, does not affect energy transmission, thereby extending the service life of the device.
