[0002] A wind turbine is a system that converts the kinetic energy of wind into electrical energy. As an important production equipment for clean energy, the internal transmission components of a wind turbine usually operate under high speed and high torque conditions. In order to ensure the stable operation of the wind turbine transmission components, a lubrication device is often installed inside the wind turbine. Therefore, the stability requirements of the lubrication system are extremely high.

In the process of lubricating oil treatment in the existing technology, a filter is usually used to simply filter it, which makes the anti-clogging effect of the lubrication device poor, and thus the pipeline blockage still occurs inside the lubrication component, which has a great impact on the transmission components of the wind turbine.

[0024] Example 1: Please refer to Figure 1-Figure 3 and Figure 5-Figure 6 The present invention provides a technical solution: a lubricating device for the interior of a wind turbine, comprising a main body mechanism 1, the main body mechanism 1 comprising an oil storage tank 11, a lubricating mechanism 2 is provided below the oil storage tank 11; The lubricating mechanism 2 includes an impurity removal unit 21 . The impurity removal unit 21 is located below the oil storage tank 11 . The impurity removal unit 21 is used to remove solid impurities such as metal impurities in the lubricating oil.

[0025] As a further limitation of the impurity removal unit 21 of the present invention, the impurity removal unit 21 includes a lubrication pump 2101, the input end of the lubrication pump 2101 is fixedly connected to the bottom surface of the oil storage tank 11, the interior of the oil storage tank 11 is filled with lubricating oil, the output end of the lubrication pump 2101 is fixedly connected to the connection box 2102, the inner top wall of the connection box 2102 is fixedly installed with an electromagnet 2103, and the metal impurities inside the lubricating oil are adsorbed on the bottom surface of the electromagnet 2103 by the electromagnet 2103, the right side of the connection box 2102 is fixedly connected to the plunger pump 2104, and the output end of the plunger pump 2104 is fixedly connected to the vortex separator The vortex separator 2105 is fixed with a plurality of piezoelectric ceramic arrays 2106 on the upper surface of the vortex separator 2105. The upper surface of the vortex separator 2105 is fixedly connected with an overflow pipe 2107. The lubricating oil in the connection box 2102 is delivered to the inside of the vortex separator 2105 at a certain pressure through the plunger pump 2104. At the same time, the lubricating oil enters the inside of the vortex separator 2105 in the direction of the tangential vortex separator 2105. At the same time, the high-frequency vibration of the piezoelectric ceramic array 2106 is combined with the acoustic flow effect of the lubricating oil in the inside of the vortex separator 2105, so that the lubricating oil forms a fixed The shear force is directed to further strengthen the centrifugal force of the vortex, so that the solid impurities inside the lubricating oil flow out through the bottom end of the vortex separator 2105, and the clear lubricating oil flows out through the overflow pipe 2107. A treatment cylinder 2108 is provided on the right side of the vortex separator 2105. The end of the overflow pipe 2107 away from the vortex separator 2105 passes through the interior of the treatment cylinder 2108. A distributor 2109 is provided below the treatment cylinder 2108. A filter screen 2110 is fixedly installed on the inner bottom wall of the treatment cylinder 2108. The bottom surface of the treatment cylinder 2108 is fixedly connected to a connecting pipe 2111. The connecting pipe 2111 is The bottom end passes through the interior of the distributor 2109, and the outer surface of the connecting pipe 2111 is fixedly connected to the solenoid valve 2112. By providing the impurity removal unit 21, the metal impurities in the lubricating oil can be removed by the electromagnet 2103 during the transportation of the lubricating oil. At the same time, the centrifugal force is used to separate the larger solid impurities from the lubricating oil in the vortex separator 2105. At the same time, the lubricating oil is further filtered through a finer filter 2110, thereby removing the impurities inside the lubricating oil more comprehensively and avoiding the lubricating oil from clogging the pipeline during transportation.

[0026] The specific implementation of this embodiment is as follows: when the lubricating device provides lubricating oil to the wind turbine, the lubricating pump 2101 is used to extract the lubricating oil in the oil storage tank 11 into the interior of the connecting box 2102, and at the same time, the attraction of the electromagnet 2103 to the metal impurities is used to adsorb the metal impurities on the bottom surface of the electromagnet 2103, and then the lubricating oil enters the interior of the plunger pump 2104. After the plunger pump 2104 pressurizes the lubricating oil, the lubricating oil enters the interior of the vortex separator 2105 at a certain pressure, and at the same time, the high-frequency vibration formed by the piezoelectric ceramic array 2106 is used to further increase the lubricating oil in the vortex separator 2105. The centrifugal force of the internal rotation of 105 causes the heavier solid impurities to be separated from the lubricating oil under the action of centrifugal force, so that the impurities are discharged through the bottom end of the vortex separator 2105, and the clear lubricating oil enters the interior of the treatment cylinder 2108 through the overflow pipe 2107. After being filtered through a relatively fine filter 2110, the lubricating oil enters the interior of the distributor 2109 through the connecting pipe 2111, and is then transported to the corresponding positions of the wind turbine set through the distributor 2109, thereby completing the function of transporting lubricating oil to the wind turbine set, thereby avoiding the phenomenon of impurity blockage management during the transportation process.

[0037] See also Figure 2 and Figure 7 A slider 314 is fixedly installed on the bottom surface of the rack plate 311, and a slide groove 315 is provided on the upper surface of the processing cylinder 2108. The slider 314 is slidably connected to the inside of the slide groove 315. The installation of the slider 314 and the slide groove 315 serves to limit the moving trajectory of the rack plate 311, thereby preventing the rack plate 311 from deviating from the moving trajectory during movement.

[0038] The specific implementation of this embodiment is as follows: during the rotation of the rotary motor 2214, the reciprocating screw rod 2213 drives the incomplete gear 309 to rotate, so that the incomplete gear 309 alternately meshes with the rack plate 311 and the connecting gear 310 during the rotation, so that the rack plate 311 drives the movable frame 312 to move back and forth, so that the movable frame 312 presses the airbag block 306. During the movement of the movable frame 312 to the right, the movable plate 308 compresses the fixed spring 307, so that the gas inside the airbag block 306 enters the interior of the airbag tube 303. This causes the airbag tube 303 to expand toward the inside of the fixed tube 302, thereby squeezing the oil pipeline 301. Similarly, when the movable frame 312 moves to the right, under the action of the elastic force of the fixed spring 307, the movable plate 308 moves to the left, so that the gas inside the airbag tube 303 returns to the inside of the airbag block 306 again, so that the airbag tube 303 continuously squeezes the oil pipeline 301 back and forth. When there are impurities inside the oil pipeline 301, they are expelled by squeezing, avoiding pipeline blockage and preventing lubricating oil from entering the interior of the wind turbine, thereby ensuring a good lubrication effect of the wind turbine.
