Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a vertical axis speed increaser of a wind generator. Background Art

[0002] Wind power generation is a renewable energy utilization method that converts wind energy into electrical energy. It has the advantages of being clean, renewable, and widely distributed. Wind turbines are mainly divided into two categories: horizontal-axis wind turbines and vertical-axis wind turbines. Vertical-axis wind turbines have unique advantages in some specific scenarios due to their unique structural characteristics, such as insensitivity to wind direction changes, compact structure, and easy installation and maintenance.

[0003] Traditional vertical axis wind turbine speed increasers mostly use planetary gear speed increasers. Although they have the advantages of compact structure and large speed ratio, planetary gear speed increasers are expensive and inconvenient to install and maintain at high altitudes. At the same time, heat dissipation is also a key factor in the operation of traditional speed increasers. High temperature environment can easily cause damage to gear components and reduce the service life of the equipment. Moreover, the entry of dust and impurities will also cause wear on the gear surface, further affecting the normal operation of the equipment. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a vertical axis speed increaser for a wind turbine.

[0005] The present invention is implemented by the following technical solution: a vertical axis speed increaser of a wind turbine, comprising a gearbox, the inner wall of the gearbox is rotatably connected to a driving gear, the surface of the driving gear is fixedly connected to a wind power rotating rod, the surface of the driving gear is meshingly connected to a driven gear, the surface of the driven gear is fixedly connected to a transmission speed increase rod, the lower surface of the gearbox is fixedly connected to a downward pressure column, the bottom end of the downward pressure column is fixedly connected to a buffer spring, and the bottom end of the buffer spring is fixedly connected to a base.

[0006] Through the above technical solution, an effective speed-increasing function is achieved through the design of the difference in the number of teeth of the driving gear and the driven gear, so that the transmission speed-increasing rod can obtain a higher speed, meeting the high speed requirement of the wind turbine. The setting of the down-pressure column and the buffer spring can effectively buffer the impact of external force, reduce the wear of the gears and other components in the gearbox caused by the impact force, and improve the stability and service life of the equipment.

[0007] As a further improvement of the above solution, the wind power rotating rod and the transmission speed increasing rod respectively pass through the gear box.

[0008] Through the above technical solution, the wind power rotor and the transmission speed increasing rod are designed to run through the gear box, ensuring that power can be smoothly transmitted from the wind impeller to the driving gear and from the driven gear to the external equipment.

[0009] As a further improvement of the above solution, the surface of the transmission speed increasing rod is rotatably connected to a shaft seat.

[0010] Through the above technical solution, the setting of the shaft seat can effectively improve the stability of the transmission speed-increasing rod, so that it can remain stable during high-speed rotation, reduce vibration and noise, and improve the operating stability and reliability of the speed increaser.

[0011] As a further improvement of the above solution, the shaft seat is fixedly connected to the inner wall of the gear box.

[0012] As a further improvement of the above solution, a plurality of holes are provided on the surface of the gear box, and a filter is fixedly connected to the inner wall of the hole.

[0013] Through the above technical solution, the filter can effectively filter the air entering the gearbox, preventing dust and impurities from entering, thereby keeping the inside of the gearbox clean, reducing gear wear caused by dust and impurities, and improving the operating efficiency and service life of the equipment.

[0014] As a further improvement of the above solution, an assembly groove is provided on the inner top wall of the gear box, and a mounting frame is fixedly mounted on the inner wall of the assembly groove by bolts.

[0015] As a further improvement of the above solution, a heat dissipation fan is provided on the inner wall of the mounting frame.

[0016] Through the above technical solution, the cooling fan can accelerate the flow of air inside the gearbox, dissipate heat in time, effectively reduce the temperature inside the gearbox, prevent damage to gears and other components due to high temperature, and improve the operating stability and reliability of the equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention uses wind power to drive the wind-driven rotating rod to rotate, thereby causing the driving gear to rotate, and utilizes the difference in the number of teeth of the driving gear and the driven gear to realize the accelerated rotation of the driven gear, thereby driving the transmission accelerating rod to output power at a higher speed, efficiently meeting the high-speed demand of the wind turbine. At the same time, the setting of the lower pressure column and the buffer spring can effectively buffer the impact of external force and reduce the damage of the impact force to the gear box. The damping rod in the base further ensures the stability of the equipment. In addition, the cooling fan accelerates the air flow in the gear box, discharges heat through the holes and slots, effectively reducing the internal temperature, and the filter screen blocks dust and impurities, keeping the interior clean, avoiding component damage caused by high temperature or impurities, and further improving the stability and reliability of the equipment.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. 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.

[0026] Example:

[0027] Please combine Figure 1-4 , a vertical axis speed increaser of a wind turbine generator in this embodiment includes a gearbox 1, the inner wall of the gearbox 1 is rotatably connected to a driving gear 2, the surface of the driving gear 2 is fixedly connected to a wind power rotating rod 3, the surface of the driving gear 2 is meshingly connected to a driven gear 4, the surface of the driven gear 4 is fixedly connected to a transmission speed increase rod 5, the lower surface of the gearbox 1 is fixedly connected to a lower pressure column 7, the bottom end of the lower pressure column 7 is fixedly connected to a buffer spring 8, the bottom end of the buffer spring 8 is fixedly connected to a base 9, the wind power rotating rod 3 is connected to the wind impeller, and when the wind drives the wind power rotating rod 3 to rotate, the rotation of the wind power rotating rod 3 drives the driven gear 4 to rotate through the driving gear 2. Due to the design difference in the number of teeth between the driving gear 2 and the driven gear 4, the driven gear 4 has fewer teeth. Therefore, when the driving gear 2 rotates, it can drive the driven gear 4 to rotate a larger number of circles, thereby causing the transmission speed-increasing rod 5 on the surface of the driven gear 4 to rotate faster. When the gearbox 1 is impacted by an external force, the lower pressure column 7 will drop, thereby compressing the buffer spring 8. The buffer spring 8 cushions the impact force through its own elastic deformation, reducing the impact of the external force on the gearbox 1. At the same time, the damping rod set inside the base 9 can further ensure the stability of the gearbox 1.

[0028] The wind-driven rotating rod 3 and the transmission speed-increasing rod 5 respectively pass through the gear box 1, so that the wind-driven rotating rod 3 can transmit the rotation of the wind impeller to the driving gear 2 in the gear box 1, and at the same time, the transmission speed-increasing rod 5 can transmit the speed-increasing rotation of the driven gear 4 to the outside of the gear box 1, thereby realizing the input and output of power.

[0029] The surface of the transmission speed increasing rod 5 is rotatably connected to the shaft seat 12, which supports and positions the transmission speed increasing rod 5, ensuring that the transmission speed increasing rod 5 can remain stable during rotation and avoiding shaking or deviation that affects the normal operation of the speed increaser.

[0030] The shaft seat 12 is fixedly connected to the inner wall of the gear box 1 .

[0031] The surface of the gear box 1 is provided with several holes and slots, and the inner wall of the hole and slot is fixedly connected with a filter 6 to realize the circulation of air inside and outside the gear box 1. At the same time, the filter 6 can effectively prevent dust, impurities, etc. from entering the interior of the gear box 1, keeping the interior of the gear box 1 clean and preventing dust and impurities from causing wear to gears and other components.

[0032] An assembly groove is formed on the inner top wall of the gear box 1 , and an installation frame 10 is fixedly mounted on the inner wall of the assembly groove by bolts.

[0033] A cooling fan 11 is provided on the inner wall of the mounting frame 10. When working, the cooling fan 11 accelerates the flow of air inside the gear box 1, and takes away the heat generated by the operation of the gears inside the gear box 1 through the air flow, thereby achieving heat dissipation inside the gear box 1, reducing the temperature inside the gear box 1, and preventing damage to components such as gears due to excessive temperature.

[0034] The implementation principle of a vertical axis speed increaser of a wind turbine in the embodiment of the present application is as follows: when wind acts on the wind impeller, the rotation of the wind impeller drives the wind rotor rod 3 to rotate, and the wind rotor rod 3 is fixedly connected to the driving gear 2, so the rotation of the wind rotor rod 3 is directly transmitted to the driving gear 2, and the driving gear 2 is meshed with the driven gear 4. Since there is a difference in the number of teeth of the driving gear 2 and the driven gear 4, and the number of teeth of the driven gear 4 is small, according to the gear transmission principle, when the driving gear 2 rotates, the driven gear 4 will rotate at a higher speed, and the driven gear 4 is fixedly connected to the transmission speed increaser 5, so that the transmission speed increaser 5 can realize the accelerated rotation, and output the power to the outside of the gear box 1 at a higher speed, meeting the high speed requirement of the wind turbine. When the gear box 1 is impacted, the lower pressure column 7 will drop accordingly, thereby compressing the buffer The spring 8 and the buffer spring 8 can effectively absorb and buffer the impact force by virtue of their own elastic deformation, reducing the impact of external force on the gear box 1. At the same time, the damping rod arranged inside the base 9 further ensures the stability of the gear box 1, and prevents the gear box 1 from shaking or shifting due to impact, thereby protecting key components such as gears from wear and tear, and improving the stability and service life of the equipment. When the cooling fan 11 is working, it will accelerate the flow of air inside the gear box 1, and discharge the heat generated by the operation of the gears inside the gear box 1 through the holes and slots, thereby achieving effective heat dissipation inside the gear box 1 and reducing the temperature inside the gear box 1. The filter 6 can effectively prevent dust, impurities, etc. from entering the gear box 1, keep the inside of the gear box 1 clean, prevent dust and impurities from causing wear to components such as gears, and further extend the service life of the equipment.

[0035] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
