Description

Technical Field

[0001] The utility model relates to the technical field of oil change for wind turbines, in particular to an offshore wind power modular oil change device. Background Art

[0002] In recent years, with the increasing reduction of non-renewable energy, sustainable energy has attracted more and more attention, which has led to the rapid development of wind power technology. However, with the rapid development of wind power equipment, maintenance issues have become increasingly important. After a period of use, the gearbox of the wind turbine will produce certain wear and tear, which will affect the normal use of the lubricating oil in the gearbox. Therefore, maintenance personnel need to regularly replace the lubricating oil in the wind turbine gearbox.

[0003] Currently, when replacing the lubricating oil in the gearbox, the waste lubricating oil in the gearbox needs to be extracted first. At the same time, in order to extend the service life of the wind turbine, the gearbox needs to be cleaned and then new lubricating oil that meets the gearbox cleanliness standards is injected. Currently, when replacing the new lubricating oil, there may be particles in the new lubricating oil. The new lubricating oil with particles entering the gearbox is likely to cause wear on the transmission between the gears, thereby affecting the service life of the gearbox. Utility Model Content

A fuel delivery pipe 8 is connected to the middle of the upper end of the barrel cover 7. A new oil barrel drain pipe 9 is connected to the rear end of the new oil barrel 6. A second solenoid valve 10 is installed outside the new oil barrel drain pipe 9. The end of the return oil pipe 3 of the waste oil barrel 2 is connected to the gearbox interface of the offshore wind power. Taking the waste oil barrel 2 as a module, the waste oil in the gearbox is discharged into the waste oil barrel 2. Finally, after opening the first solenoid valve 5, the first solenoid valve 5 is externally connected to a power supply and a switch. In this way, the waste oil in the waste oil barrel 2 can be discharged from the waste oil barrel drain pipe 4. The end of the fuel delivery pipe 8 of the new oil barrel 6 is connected to the gearbox interface of the offshore wind power. Taking the new oil barrel 6 as another module, in this way, the new oil in the new oil barrel 6 is pumped into the new oil through the new oil barrel drain pipe 9 by a pump. The second solenoid valve 10 is externally connected to a power supply and a switch. In this way, new oil can be stored and enter the new oil barrel 6. In this way, the new oil in the new oil barrel 6 can be input into the gearbox of the offshore wind power along the fuel delivery pipe 8.

[0017] A fixed disk 11 is fixed to the inner wall of the barrel cover 7. A spiral enclosing plate 19 is fixed to the upper end of the fixed disk 11. The upper end of the spiral enclosing plate 19 is fixed to the top end of the inner wall of the barrel cover 7. A filter screen 20 is fixed to the inner side of the spiral enclosing plate 19. The upper and lower ends of the filter screen 20 are respectively fixed to the top end of the inner wall of the barrel cover 7 and the upper end of the fixed disk 11. An oil delivery assembly is installed on one side of the lower end of the fixed disk 11. The oil delivery assembly includes an oil pump 12, a three-way valve assembly, a top pipe 14, an inclined pipe 15, a side pipe 16 and a bottom pipe 17. The oil pump 12 is fixed to the fixed disk 11. The three-way valve assembly is arranged on the right side of the oil pump 12. The top pipe 14 is connected to the upper part of the three-way valve assembly. The upper part of the top pipe 14 penetrates through the fixed disk 11 and extends to the inner side of the spiral enclosing plate 19. The bottom pipe 17 is connected to the lower part of the three-way valve assembly. The side pipe 16 is connected to the left part of the three-way valve assembly. The end of the side pipe 16 is connected to the oil suction end of the oil pump 12. The inclined pipe 15 is connected to the oil discharge end of the oil pump 12. The end of the inclined pipe 15 is communicated with the top pipe 14. The three-way valve assembly includes a three-way valve body 13, a motor 18 and a three-way valve ball 21. The three ends of the three-way valve body 13 are respectively connected to the top pipe 14, the side pipe 16 and the bottom pipe 17. The three-way valve ball 21 is rotatably connected inside the three-way valve body 13. The motor 18 is fixedly installed at the front end of the three-way valve body 13. The end of the output shaft of the motor 18 penetrates into the three-way valve body 13 and is fixed to the three-way valve ball 21. A T-shaped channel 22 is arranged inside the three-way valve ball 21. The side pipe 16 is communicated with the bottom pipe 17 through the T-shaped channel 22. The bottom pipe 17 is communicated with the top pipe 14 through the T-shaped channel 22. When the oil delivery pipe 8 inputs new oil into the gearbox of the offshore wind turbine, through the oil pump 12, the oil pump 12 is externally connected to a power supply and a switch. In this way, the bottom pipe 17 sucks in the new oil, then enters the side pipe 16 along the T-shaped channel 22, and then is discharged into the top pipe 14 from the inclined pipe 15, and then enters the inner side of the spiral enclosing plate 19 from the top pipe 14. In this way, the new oil flows spirally from the outside to the inside along the spiral enclosing plate 19, passes through the filter screen 20 to filter the new oil, and then the filtered new oil is input into the gearbox of the offshore wind turbine through the oil delivery pipe 8, so as to prevent particles from entering the gearbox mixed with the new oil.

[0018] When the filter screen 20 needs to be cleaned, first rotate the three-way valve ball 21 counterclockwise by ninety degrees. The motor 18 is externally connected to a controller, a reversing switch, and a power supply. The reversing switch can be operated to enable the controller to control the motor 18 to rotate forward or backward by ninety degrees. In this way, after the motor 18 rotates backward by ninety degrees, it can drive the three-way valve ball 21 to rotate counterclockwise by ninety degrees, so that the bottom pipe 17 is connected to the top pipe 14 through the T-shaped channel 22. Then, connect the water pump through the oil delivery pipe 8. The water pump pumps water into the oil delivery pipe 8, and then the oil delivery pipe 8 inputs the water into the spiral baffle 19 and flows in a spiral from the inside to the outside, so as to backwash the filter screen 20. Then the flushing water enters the top pipe 14. Because the inclined pipe 15 is in an inclined state, the flushing water will not enter the inclined pipe 15. After that, the flushing water will be discharged from the bottom pipe 17 along the T-shaped channel 22 into the new oil barrel 6, and then discharged to the outside through the new oil barrel drain pipe 9 of the new oil barrel 6, thus improving the practicability.
