Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, in particular to a transmission mechanism of a maintenance-free wind turbine. Background Art

[0002] A wind turbine is a device that uses wind energy to generate electricity. Its core principle is to convert the kinetic energy of wind into mechanical work, which then drives the rotor to rotate and ultimately outputs alternating current. A wind turbine captures wind energy through a rotor. The rotor rotates under the action of wind, converting the kinetic energy of wind into mechanical energy of the rotor shaft. The mechanical energy is transmitted to the generator through a transmission device (such as a gearbox), and the generator converts the mechanical energy into electrical energy.

[0003] The transmission device of a wind turbine is generally a gearbox. When the fan blades rotate, they drive the wind rotor shaft to rotate. When the wind rotor shaft rotates, the mechanical energy needs to be transmitted to the generator through the gearbox and converted into electrical energy. There are multiple sets of gear transmissions inside the gearbox. Therefore, wind power gear oil needs to be added to the inside of the gearbox to lubricate and protect the gears. After long-term use of wind power gear oil, external pollutants such as sand and dust will enter the oil to form abrasive particles, which will damage the surface of the gears.

[0022] The present invention has the following beneficial effects:

[0023] The wind wheel of the present invention is driven by wind force to drive the wind wheel shaft to rotate inside the support frame. When the wind wheel shaft rotates, the mechanical energy is transmitted to the inside of the generator through the gear box and is transmitted as electrical energy. When the wind turbine gear oil inside the gear box needs to be processed, the electric push rod is started to push the connecting plate to move. When the connecting plate moves, it pulls the telescopic rod to extend to the extreme. When the telescopic rod is extended to the extreme, it pushes the slide bar to slide. When the slide bar moves, it pulls the vertical plate to move. When the vertical plate moves, it will tilt. When the vertical plate tilts, the top of the vertical plate will move downward. The arc plate slides on the surface of the slide plate as the vertical plate moves downward and separates from the inner wall of the through-hole plate. At this time, the gear box is The wind turbine gear oil will enter the interior of the extension frame. After entering the interior of the extension frame, the wind turbine gear oil flows into the interior of the separation frame through the connecting pipe. The sieve plate will filter the wind turbine gear oil in the separation frame. The filtered wind turbine gear oil will flow into the lower interior of the separation frame. After the wind turbine gear oil passes through the sieve plate, the internal abrasive particles will be stored on the top of the sieve plate and separated from the wind turbine gear oil, avoiding the abrasive particles in the wind turbine gear oil from damaging the parts inside the gear box, thereby increasing the service life of the gear box. Start the water pump to start operation. The water pump will draw the filtered wind turbine gear oil into the interior of the circulation pipe and transmit it to the interior of the gear box for recycling.

[0024] After the telescopic rod of the present invention is extended to the limit, the electric push rod can push the telescopic rod to retract when it is contracted. When the electric push rod pushes the telescopic rod to extend and contract reciprocally, the linkage plate will push the scraper to move on the surface of the sieve plate through the push rod. The scraper will clean the surface of the sieve plate when it moves, so as to prevent abrasive particles in the wind power gear oil from accumulating on the top of the sieve plate and affecting the filtering effect. The filtered wind power gear oil is transmitted to the interior of the gear box for recycling. The wind power gear oil is used to protect the parts inside the gear box, so as to prevent the parts inside the gear box from wearing out too quickly and requiring frequent maintenance.

[0025] When the push rod of the present invention moves, it pushes the movable plate to squeeze the synchronous plate. The synchronous plate can limit the movable plate, so that when the movable plate squeezes the synchronous plate, it pushes the synchronous plate to move upward. When the synchronous plate moves, it pushes the sealing plate to move upward through the connection between the lifting plate and the movable frame. The sealing plate moves upward to push the air pressure inside the cylindrical frame to be transmitted to the inside of the bent pipe. The compressed air in the bent pipe will be transmitted to the inside of the gear box through the connection between the transmission pipe and the mounting frame. After the air pressure enters the interior of the gear box, the wind power gear oil inside it can be quickly pushed into the interior of the extension frame for separation and processing, thereby improving the processing efficiency of the wind power gear oil.

[0026] When the wind turbine gear oil in the gear box needs to be replaced, the present invention transmits the wind turbine gear oil in the gear box to the inside of the separation frame through the extension frame, starts the electric rod to push the moving ring to move toward the end away from the gear box, and when the moving ring moves, it pushes the disc to slide inside the filling tank and separate from the top of the circular tube through the pull rod. At this time, the wind turbine gear oil in the filling tank will be transmitted to the inside of the gear box through the circular tube to replace the wind turbine gear oil, so that the wind turbine gear oil can be replaced in time.
