Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and specifically to a safety protection device for a wind power component and a method for using the same. Background Art

[0002] A wind turbine is one of the important sources of current renewable energy. A wind turbine converts wind energy into mechanical work. The mechanical work drives the rotor to rotate, and finally outputs alternating current power equipment. A wind turbine generally consists of components such as a wind wheel, a generator (including devices), a yaw device (tail fin), a tower, a speed limit safety mechanism, and an energy storage device. The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of wind force. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates to generate electricity driven by the wind wheel shaft.

[0003] After retrieval, a safety protection device for a wind power component disclosed in a utility model patent with the Chinese patent publication number "CN119641572A" relates to the technical field of wind power generation, including: a nacelle, a tower barrel is fixedly installed at the bottom end of the nacelle, and a first rotating shaft is provided at the left end of the nacelle. A fan blade is fixedly installed on the first rotating shaft. The other end of the first rotating shaft is connected to one end of a gearbox. The other end of the gearbox is connected to a generator through a second rotating shaft. The bottom end of the gearbox is fixedly installed on a support seat, and a motor protection mechanism is arranged at the bottom end of the generator; by setting the motor protection mechanism and through the operation of the motor protection mechanism, the technical problem proposed in the background art is effectively improved: in the prior art, most protection devices only focus on the protection of a single factor, such as lightning protection or wind and snow protection, and lack the safety protection of internal wind power components.

[0004] Although this device achieves a protection effect by setting a motor protection mechanism, since this device realizes the lubrication of the gearbox through multiple complex components such as a gear lubrication mechanism, it increases the manufacturing and maintenance costs, and once a certain component is damaged, the repair difficulty and cost are relatively high; at the same time, this device uses a fixedly installed filter plate and a water pump to extract the lubricating fluid. If it runs for a long time, the filter plate may affect the circulation efficiency. Therefore, a safety protection device for a wind power component and a method for using the same are proposed to solve the above-mentioned problems. Summary of the Invention

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1

[0045] Please refer to Figures 1-7 , a safety protection device for a wind power component, including a tower pole 1, a nacelle 2, a generator 3, a rotating shaft 4, a gearbox 5, a rotating hub 6 and a blade 7. The nacelle 2 is welded and installed at the top of the tower pole 1. The generator 3 is installed inside the nacelle 2. One end of the said generator 3 is fixedly installed with a rotating shaft 4. One end of the rotating shaft 4 is fixedly installed with a gearbox 5. The rotating hub 6 is installed on the nacelle 2. The blades 7 are fixedly installed on the surface of the rotating hub 6.

[0046] In this embodiment, the blade 7 drives the rotating hub 6 to rotate under the action of wind force. The rotating hub 6 transmits the power to the gearbox 5 through the rotating shaft 4. After the gearbox 5 adjusts the rotation speed, it drives the generator 3 to generate electricity through the rotating shaft 4, completing the conversion of wind energy into electrical energy.

[0047] A shock absorption component 9 is fixedly installed inside the nacelle 2. The shock absorption component 9 includes an installation frame 901 fixedly installed on the inner bottom wall of the nacelle 2. Two sliding rods 902 are fixedly installed inside the installation frame 901. Sliding blocks 903 are slidably installed on the surfaces of the two sliding rods 902. A support plate 904 is welded between the two sliding blocks 903. A fixed plate 905 is fixedly installed on the inner bottom wall of the installation frame 901. Two inclined blocks 906 are slidably installed on the surface of the fixed plate 905. A shock absorber 907 is fixedly installed between the two inclined blocks 906 and on the top of the fixed plate 905. Two vertical rods 908 are fixedly installed at the bottom of the support plate 904. Pulleys 909 are rotatably installed on the surfaces of the two vertical rods 908. Dampers 910 are fixedly installed on the left and right sides of the fixed plate 905 at the bottom of the support plate 904.

[0048] A through hole is opened at the top of the installation frame 901. A rubber pad is fixedly installed at the top of the support plate 904. The bottom of the generator 3 passes through the through hole and extends into the installation frame 901 and is installed with the support plate 904 through bolts. One ends of the two dampers 910 away from the support plate 904 are fixedly connected to the inner bottom wall of the installation frame 901. And the two pulleys 909 are both slidably connected to the surface of the inclined block 906.

[0049] In this embodiment, when the generator 3 operates to generate vibration, the vibration is transmitted to the support plate 904, driving the slider 903 to slide on the surface of the slide bar 902, changing the position of the support plate 904. The vertical rod 908 and the pulley 909 at the bottom of the support plate 904 move accordingly, squeezing the inclined block 906 on the surface of the fixed plate 905, prompting the inclined block 906 to compress the shock absorber 907, converting the vibration energy into the elastic potential energy of the shock absorber 907. At the same time, the dampers 910 on the left and right sides at the bottom of the support plate 904 work synchronously to consume the vibration energy and inhibit the excessive shaking of the support plate 904. The sliding fit between the pulley 909 and the inclined block 906 further disperses and buffers the vibration impact force, reducing the vibration transmitted to the nacelle 2 and other components.

[0050] In this embodiment, by setting the combination of the slider 903 and the slide bar 902, the shock absorber 907, the damper 910, and the pulley 909 and the inclined block 906, the vibration generated during the operation of the generator 3 can be effectively absorbed and buffered, reducing the risk of loosening and wear of components caused by vibration, and extending the service life of the generator 3 and other related components. Second, by reducing the vibration transmission through the shock absorption component 9, the operating noise of the equipment in the nacelle 2 can be reduced, the impact on the surrounding environment can be reduced, and at the same time, the stability and reliability of the wind power component operation can be improved, ensuring the power generation efficiency and power quality.

A method for using a safety protection device of a wind power component, which is applied to the safety protection device of a wind power component described in claims 1-8, and is characterized in that: It includes the following usage steps: S1: During use, the blade (7) drives the rotating hub (6) to rotate under the action of wind force. The rotating hub (6) transmits the power to the gearbox (5) through the rotating shaft (4). After the gearbox (5) adjusts the rotational speed, it then drives the generator (3) to generate electricity through the rotating shaft (4), completing the conversion from wind energy to electrical energy; S2: When the vibration generated during the operation of the generator (3) is first transmitted to the support plate (904), the support plate (904) drives the slider (903) to slide on the slide bar (902). At the same time, the pulley (909) of the bottom vertical rod (908) presses against the inclined block (906), and the inclined block (906) compresses the shock absorber (907).

The lubricating oil after use in the gearbox (5) is pumped back by the pump body (1151) through the connecting pipe (1152), enters the working filter plate A (1154) or the spare filter plate B (1155) for filtration through the three-way electric valve (1153). The filtered lubricating oil flows back to the lubricating oil cavity (112) through the oil return pipe (1156), realizing the recycling of the lubricating oil; S4: When it is necessary to clean the filter plate, the cleaning liquid in the cleaning liquid tank (1161), after the solenoid valve (1162) is opened, enters the backwashing pipeline (1163) through the liquid outlet pipe, and is sprayed onto the working filter plate A (1154) or the spare filter plate B (1155) through the high-pressure nozzle (1164) to wash away the impurities on the filter plate. The waste liquid generated by the washing flows into the waste liquid tank (1165) through the drain port at the bottom of the filter plate; S5: The heat insulation layer (802) on the protection plate (801) maintains the stability of the temperature inside the nacelle (2), and the anti-corrosion coating (803) prevents the nacelle (2) from being corroded. The bird repeller (12) emits a bird repelling signal through the sound outlet hole (13) to prevent birds from approaching the nacelle (2), reducing the interference and damage of birds to the equipment.
