Description

Technical Field

[0001] This invention relates to the technical field of wind turbine lubrication, and more particularly to a lubrication device for use inside wind turbines. Background Technology

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

[0003] In practical applications, existing lubrication devices often experience pipe blockage due to the deposition of impurities in the lubricating oil and the accumulation of metal debris from long-term operation. This can lead to failures such as bearing wear and gearbox overheating. Current technologies typically use filters to simply filter the lubricating oil, resulting in poor anti-clogging performance of the lubrication device. Consequently, pipe blockage can still occur inside the lubrication components, significantly impacting the transmission parts of the wind turbine. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] By incorporating a cleanup unit, the lubricating oil is transported using electromagnets to remove metallic impurities. Simultaneously, centrifugal force separates larger solid impurities from the lubricating oil within a vortex separator. Furthermore, the lubricating oil undergoes further filtration through a finer filter screen, thus comprehensively removing impurities from the lubricating oil and preventing pipeline blockage during transport.

[0022] By setting up a collection unit, the impurities adsorbed on the electromagnet and separated from the filter screen are collected after the lubricating oil is transported. This prevents impurities from remaining inside the device during the next lubricating oil transport process, thus preventing impurities from entering the wind turbine with the lubricating oil again and further preventing pipeline blockage of the lubrication device.

[0023] By incorporating a squeezing mechanism, the device continuously supplies and discharges gas into the airbag tube during the impurity collection process. This causes the airbag tube to continuously squeeze the oil delivery pipe, thereby clearing any blockages. This further prevents pipe blockages during the delivery of lubricating oil to the wind turbine, thus avoiding insufficient lubrication that could lead to bearing wear and gearbox overheating in the wind turbine.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0039] Example 1: Please refer to Figures 1-3 and Figures 5-6 The present invention provides a technical solution: a lubrication device for the inside of a wind turbine, including a main body mechanism 1, the main body mechanism 1 including an oil storage tank 11, and a lubrication mechanism 2 disposed below the oil storage tank 11;

[0040] The lubrication mechanism 2 includes a cleaning unit 21, which is located below the oil storage tank 11. The cleaning unit 21 is used to remove solid impurities such as metal impurities from inside the lubricating oil.

[0041] As a further definition 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, and the oil storage tank 11 is filled with lubricating oil. The output end of the lubrication pump 2101 is fixedly connected to a connecting box 2102. An electromagnet 2103 is fixedly installed on the inner top wall of the connecting box 2102. The electromagnet 2103 attracts metallic impurities inside the lubricating oil to the bottom surface of the electromagnet 2103. A plunger pump 2104 is fixedly connected to the right side of the connecting box 2102, and the output end of the plunger pump 2104 is fixedly connected to a vortex separator. The vortex separator 2105 has several piezoelectric ceramic elements 2106 fixedly mounted on its upper surface. An overflow pipe 2107 is fixedly connected to the upper surface of the vortex separator 2105. A plunger pump 2104 delivers lubricating oil from the connection box 2102 to the vortex separator 2105 at a certain pressure. Simultaneously, the lubricating oil enters the vortex separator 2105 tangentially. Combined with the high-frequency vibration of the piezoelectric ceramic elements 2106, this creates an acoustic flow effect within the vortex separator 2105, causing the lubricating oil to form a steady flow. The shear force further enhances the centrifugal force of the vortex, causing solid impurities inside the lubricating oil to flow out through the bottom of the vortex separator 2105, while clear lubricating oil flows out through the overflow pipe 2107. A processing cylinder 2108 is located on the right side of the vortex separator 2105. The end of the overflow pipe 2107 away from the vortex separator 2105 extends into the interior of the processing cylinder 2108. A distributor 2109 is located below the processing cylinder 2108. A filter screen 2110 is fixedly installed on the inner bottom wall of the processing cylinder 2108. A connecting pipe 2111 is fixedly connected to the bottom surface of the processing cylinder 2108. The bottom end extends into the interior of the distributor 2109. The outer surface of the connecting pipe 2111 is fixedly connected to the solenoid valve 2112. By setting up the impurity removal unit 21, the lubricating oil removes metal impurities in the lubricating oil during the transportation process by the electromagnet 2103. At the same time, the lubricating oil is separated from the lubricating oil by the centrifugal force inside the vortex separator 2105. The lubricating oil is further filtered by the finer filter screen 2110, thereby removing impurities inside the lubricating oil more comprehensively and preventing the lubricating oil from clogging the pipeline during transportation.

[0042] The specific implementation of this embodiment is as follows: When the lubrication device supplies lubricating oil to the wind turbine, the lubrication pump 2101 draws the lubricating oil from the oil storage tank 11 into the connecting box 2102. Simultaneously, the electromagnet 2103 attracts metal impurities, adsorbing them onto the bottom surface of the electromagnet 2103. The lubricating oil then enters the plunger pump 2104. After being pressurized by the plunger pump 2104, the lubricating oil enters the vortex separator 2105 at a certain pressure. Simultaneously, the high-frequency vibration generated by the piezoelectric ceramic array 2106 further increases the pressure of the lubricating oil in the vortex separator 2105. The centrifugal force generated by the internal rotation of 105 causes heavier solid impurities to separate from the lubricating oil under the action of centrifugal force. As a result, the impurities are discharged through the bottom of the vortex separator 2105, while the clear lubricating oil enters the interior of the processing cylinder 2108 through the overflow pipe 2107. After being filtered by a finer filter screen 2110, the lubricating oil enters the interior of the distributor 2109 through the connecting pipe 2111. Then, the distributor 2109 delivers the lubricating oil to the corresponding positions of the wind turbine, thereby completing the function of delivering lubricating oil to the wind turbine and avoiding the phenomenon of impurities clogging the system during the delivery process.

[0043] Example 2: Please refer to Figures 1-6 and Figure 9 The present invention provides a technical solution: a lubrication device for the inside of a wind turbine. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The lubrication mechanism 2 also includes a collection unit 22, which is located on the right side of the oil storage tank 11. The impurity removal unit 21 and the collection unit 22 are used together. The collection unit 22 is used to collect and process the separated impurities.

[0044] As a further definition of the collecting unit 22 of the present invention, the collecting unit 22 includes a threaded rod 2201, which is rotatably connected to the inside of the connecting box 2102. A rotating motor 2202 is fixedly installed on the right side of the connecting box 2102. The output end of the rotating motor 2202 extends into the inside of the connecting box 2102 and is fixedly connected to the right end of the threaded rod 2201. A movable box 2203 is threadedly connected to the outer surface of the threaded rod 2201. A plurality of connecting springs 2204 are fixedly installed on the inner bottom wall of the movable box 2203. A scraper 2205 is fixedly installed on the top of the plurality of connecting springs 2204. The outer surface of the scraper 2205 contacts the bottom surface of the electromagnet 2103. The elastic force of the connecting springs 2204 is used to make... The scraper 2205 achieves good contact with the bottom surface of the electromagnet 2103, allowing it to remove impurities. A fixed box 2206 is fixedly installed on the inner top wall of the connecting box 2102. As the moving box 2203 moves below the fixed box 2206, the fixed box 2206 presses against the scraper 2205, facilitating its entry into the fixed box 2206. Simultaneously, the moving box 2203 overlaps with the fixed box 2206, facilitating the collection of scraped metal impurities. A collection pipe 2207 is fixedly connected to the upper surface of the fixed box 2206. A collection box 2208 and an air pump 2209 are fixedly installed on the back of the connecting box 2102. The air inlet of 209 extends into the interior of the collection box 2208. The end of the collection pipe 2207 furthest from the connecting box 2102 extends into the interior of the collection box 2208. A dustproof net 2210 is fixedly installed on the inner wall of the collection box 2208. The air pump 2209 discharges the gas inside the collection box 2208, creating a negative pressure inside, allowing metal impurities to enter. A water pump 2211 is fixedly installed on the upper surface of the collection box 2208. A water spray pipe 2212 is fixedly installed on the inner wall of the collection box 2208. The output end of the water pump 2211 extends into the interior of the water spray pipe 2212. A reciprocating screw 2213 is rotatably connected inside the processing cylinder 2108. A rotary motor 2214 is fixedly installed on the upper surface of 08. The top end of the reciprocating screw 2213 is fixedly connected to the output end of the rotary motor 2214. A moving ring 2215 is threadedly connected to the outer surface of the reciprocating screw 2213. Several nozzles 2216 are fixedly installed on the inner wall of the moving ring 2215. The ends of the nozzles 2216 that are close to each other are fixedly connected to a conveying pipe 2217. The end of the conveying pipe 2217 away from the nozzles 2216 passes through the interior of the water spray pipe 2212. The water pump 2211 is fixedly connected to the external water supply pipe, so that the water pump 2211 draws external water into the interior of the water spray pipe 2212 and the nozzles 2216 respectively, thereby rinsing the dust screen 2210 and the filter screen 2110.

[0045] Please see Figure 2 , Figure 5 and Figure 6 The bottom surface of the collection box 2208 is fixedly connected to the first sewage pipe 2218, and the outer surface of the treatment cylinder 2108 is fixedly connected to the second sewage pipe 2219. The outer surfaces of the first sewage pipe 2218 and the second sewage pipe 2219 are both fixedly connected to valve bodies to control their opening and closing. The first sewage pipe 2218 and the second sewage pipe 2219 are fixedly connected to the external impurity storage box through pipes to discharge sewage.

[0046] Please see Figure 4 Several telescopic rods 2220 are fixedly installed on the inner bottom wall of the mobile box 2203. The telescopic end of each telescopic rod 2220 is fixedly connected to the bottom surface of the scraper 2205. The installation of the telescopic rods 2220 restricts the movement trajectory of the scraper 2205, thereby preventing the scraper 2205 from deviating from the movement trajectory when moving, and thus ensuring the stability of the movement of the scraper 2205.

[0047] Please see Figure 2 and Figure 6 The moving ring 2215 has a sliding connection of a limiting rod 2221 inside. The two ends of the limiting rod 2221 that are far apart from each other are fixedly connected to the inner wall of the processing cylinder 2108. The installation of the limiting rod 2221 restricts the movement trajectory of the moving ring 2215, thereby preventing the moving ring 2215 from rotating during movement and ensuring the stability of the movement of the moving ring 2215.

[0048] Please see Figure 3 The movable box 2203 has two sliding rods 2222 inside. The two ends of each sliding rod 2222 are fixedly connected to the inner wall of the connecting box 2102. The installation of the sliding rods 2222 restricts the movement trajectory of the connecting box 2102, thereby ensuring the stability of the movement of the connecting box 2102.

[0049] The specific implementation of this embodiment is as follows: After the lubricating oil delivery is completed, the power provided by the rotating motor 2202 drives the threaded rod 2201 to rotate, thereby causing the threaded rod 2201 to move the movable box 2203. At the same time, the movable box 2203 drives the scraper 2205 to scrape away the metal impurities on the bottom surface of the electromagnet 2103, causing the metal impurities to fall into the interior of the movable box 2203. Then, the movable box 2203 moves below the fixed box 2206 and overlaps with the fixed box 2206. The power provided by the air pump 2209 creates a negative pressure inside the collection box 2208, causing the metal impurities to enter the interior of the collection box 2208 through the collection pipe 2207, thereby collecting the metal impurities. To prevent the lubricating oil from affecting the adsorption of metal impurities during subsequent transportation, the water source is sprayed out through the spray pipe 2212 and the delivery pipe 2217 using the power provided by the water pump 2211. At the same time, the reciprocating screw 2213 is rotated by the power provided by the rotary motor 2214. This causes the reciprocating screw 2213 to drive the moving ring 2215 to move back and forth inside the processing cylinder 2108. As a result, the water source is sprayed onto the outer surfaces of the dustproof net 2210 and the filter screen 2110. The water source carries the separated impurities and is discharged through the first drain pipe 2218 and the second drain pipe 2219, respectively, to prevent impurities from remaining inside the device and entering the wind turbine during the subsequent lubricating oil transportation process.

[0050] Example 3: Please refer to Figures 1-2 and Figures 7-9 The present invention provides a technical solution: a lubrication device for the inside of a wind turbine. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A squeezing mechanism 3 is provided on the right side of the oil storage tank 11. The lubrication mechanism 2 and the squeezing mechanism 3 are used together. The squeezing mechanism 3 is used to reciprocate the squeezing of the pipeline that transports lubricating oil.

[0051] As a further definition of the extrusion mechanism 3 of the present invention, the extrusion mechanism 3 includes two oil supply pipes 301. The end of each oil supply pipe 301 near the distributor 2109 is fixedly connected to the output end of the distributor 2109. A fixing pipe 302 is sleeved on the outer surface of each oil supply pipe 301. The fixing pipe 302 is made of PVC material, so that the pipe has a certain degree of hardness and elasticity. An air bladder pipe 303 is fixedly installed on the inner wall of each fixing pipe 302. The outer surface of each air bladder pipe 303 is in contact with the outer surface of the oil supply pipe 301. The outer surfaces of the two air bladder pipes 303 are fixedly connected to an air inlet pipe 304. A fixing plate 305 is fixedly installed on the upper surface of the processing cylinder 2108. An air bladder block 306 is fixedly installed on the left side of the fixing plate 305. The air bladder block 306 and the air bladder pipe 301 are connected together. The interior of the airbag 306 is filled with gas. Two sets of fixing springs 307 are fixedly installed on the inner wall of the airbag block 306. The left end of the two sets of fixing springs 307 is fixedly installed with a moving plate 308. The left side of the moving plate 308 is in contact with the inner wall of the airbag block 306. An incomplete gear 309 is fixedly installed on the outer surface of the reciprocating screw 2213. A connecting gear 310 is rotatably connected to the upper surface of the processing cylinder 2108. A rack plate 311 is meshed with the outer surface of the connecting gear 310. The incomplete gear 309 alternately meshes with the rack plate 311 and the connecting gear 310, so that the rack plate 311 reciprocates during the rotation of the incomplete gear 309. A moving frame 312 is fixedly installed on the right side of the rack plate 311. The right side of the moving frame 312 is in contact with the left side of the airbag block 306.

[0052] Please see Figure 7 Two sets of telescopic columns 313 are fixedly installed on the inner wall of the airbag block 306. The telescopic end of each telescopic column 313 is fixedly connected to the right side of the moving plate 308. The installation of the telescopic columns 313 plays a role in restricting the movement trajectory of the moving plate 308, thereby preventing the moving plate 308 from deviating from the movement trajectory when moving.

[0053] Please see Figure 2 and Figure 7 A slider 314 is fixedly installed on the bottom surface of the rack plate 311, and a groove 315 is provided on the upper surface of the processing cylinder 2108. The slider 314 is slidably connected inside the groove 315. The installation of the slider 314 and the groove 315 plays a role in restricting the movement trajectory of the rack plate 311, thereby preventing the rack plate 311 from deviating from the movement trajectory when moving.

[0054] The specific implementation of this embodiment is as follows: During the rotation of the rotary motor 2214, the reciprocating screw 2213 drives the incomplete gear 309 to rotate, thereby causing the incomplete gear 309 to alternately mesh with the rack plate 311 and the connecting gear 310 during rotation. This causes the rack plate 311 to drive the moving frame 312 to reciprocate, pressing the airbag block 306. During the movement of the moving frame 312 to the right, the moving plate 308 compresses the fixing spring 307, allowing the gas inside the airbag block 306 to enter the airbag tube 303. This causes the airbag tube 303 to expand into the fixed tube 302, thereby squeezing the oil delivery pipe 301. Similarly, when the moving frame 312 moves to the right, the moving plate 308 moves to the left under the action of the fixed spring 307, causing the gas inside the airbag tube 303 to return to the airbag block 306. This causes the airbag tube 303 to continuously squeeze the oil delivery pipe 301. When there are impurities inside the oil delivery pipe 301, they are discharged through squeezing, preventing the pipe from being blocked and the lubricating oil from entering the wind turbine, thus ensuring good lubrication of the wind turbine.
