[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. In a broad sense, wind energy is also solar energy, so it can also be said that a wind turbine is a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium. A wind turbine generally consists of a wind rotor, a generator (including a device), a rectifier (tail), a tower, a speed limit safety mechanism, and an energy storage device. It is often used in areas where wind energy is more developed. The working principle of a wind turbine is relatively simple, and the wind rotor rotates under the action of wind.

[0003] However, the existing wind turbines still have certain shortcomings when in use. Since the wind turbines are rotated mechanically, friction will occur in the driving components when the machinery rotates for a long time, thereby reducing the rotation rate of the machinery and reducing the efficiency of power generation. At the same time, long-term friction of the driving components will also affect the service life of the driving components, causing damage to the driving components and reducing the protection effect of the driving components.

At the same time, the friction of the driving parts for a long time will also affect the service life of the driving parts, causing damage to the driving parts and reducing the protection effect of the driving parts.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0024] A lubrication structure for a driving component of a wind turbine generator comprises a support column 1, a top plate 2 is fixedly connected to the top of the support column 1, a fixing box 3 is fixedly connected to the top of the top plate 2, a round rod 5 is rotatably connected inside the fixing box 3, the round rod 5 extends to the outside of the fixing box 3, a fan blade 4 is fixedly connected to the outside of the round rod 5, a driven gear 18 is fixedly connected to the outside of the round rod 5, a generator body 20 is fixedly connected inside the fixing box 3, a driving gear 19 is rotatably connected to the side of the generator body 20, the driving gear 19 is arranged on the side of the driven gear 18, the driving gear 19 and the driven gear 18 are meshed, and a noise monitor 17 and a control switch 16 are fixedly connected to the inner wall of the fixing box 3 respectively.

[0025] In this embodiment, Figure 1 and Figure 3 As shown, the top of the fixed box 3 is fixedly connected to the oil storage tank 6, the bottom of the oil storage tank 6 is fixedly connected to the oil dripping tube 10, the bottom of the oil dripping tube 10 extends into the fixed box 3, the oil dripping tube 10 is fixedly connected to the top of the meshing point of the driven gear 18 and the driving gear 19, a foam pad 12 is slidably connected in the oil storage tank 6, the top of the foam pad 12 is fixedly connected to the connecting plate 13, the top of the oil storage tank 6 is abutted with a cover plate 9, the top of the cover plate 9 is fixedly connected to a pull ring 8, and the inner bottom wall of the cover plate 9 is fixedly connected to a pressure sensor 15.

[0026] Among them, the lubricating oil in the oil storage tank 6 can be dripped to the meshing point of the two gears through the oil dripping tube 10, so as to lubricate the driving components of the generator body 20 and avoid the driving components from being damaged due to long-term wear. At the same time, when the foam pad 12 and the extrusion rod 14 move downward, the pressure sensor 15 cannot detect the pressure, so that the alarm light 7 flashes, prompting timely addition of lubricating oil, so that the lubricating oil in the oil storage tank 6 can be continuously dripped.

[0027] In this embodiment, Figure 2 and Figure 4 As shown, an extrusion rod 14 is fixedly connected to the top of the connecting plate 13, and the extrusion rod 14 is opposite to the pressure sensor 15, and the surface of the extrusion rod 14 and the pressure sensor 15 are against each other. An alarm light 7 is fixedly connected to the outer surface of the oil storage tank 6, and the alarm light 7 is electrically connected to the pressure sensor 15. The output end of the noise monitor 17 is electrically connected to the input end of the control switch 16, and the output end of the control switch 16 is electrically connected to the input end of the electric valve 11. A plurality of fan blades 4 are provided, and the plurality of fan blades 4 are evenly distributed on the outer surface of the round rod 5 at equal angles, and the sizes of the plurality of fan blades 4 are the same.

[0028] Among them, the noise monitor 17 can be used to monitor the noise of the driven gear 18 and the driving gear 19 when they are engaged. When the presence of noise is detected, the electric valve 11 is opened by the control switch 16 to allow lubricating oil to drip between the driven gear 18 and the driving gear 19, so as to lubricate the driven gear 18 and the driving gear 19, thereby improving the automation of the lubrication mechanism during use and making it more convenient to use.

[0029] Working process of the utility model: when the lubrication structure of the driving part of the wind turbine designed by the present invention is working, the fan blade 4 is rotated by the wind force, thereby driving the round rod 5 and the driven gear 18 to rotate. Since the driven gear 18 and the driving gear 19 are meshing, the driving gear 19 can be driven to rotate, and the mechanical energy generated by the rotation of the driving gear 19 is converted into electrical energy through the generator body 20, and the noise when the driven gear 18 and the driving gear 19 are meshing is monitored by the noise monitor 17. When noise occurs, the electric valve 11 is opened by the control switch 16, and then the lubricating oil is dripped on the meshing point of the driven gear 18 and the driving gear 19 through the oil drip tube 10. When the lubricating oil gradually decreases, the foam pad 12 drives the connecting plate 13 and the extrusion rod 14 to move downward, so that the extrusion rod 14 no longer squeezes the pressure sensor 15. At this time, the alarm light 7 flashes, thereby prompting people to add lubricating oil in time, so that the lubricating device is more practical when used.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
