Description

Gearbox oil inline dedicated filtration device Technical Field

[0001] This utility model relates to gear oil filtration, and in particular to a dedicated online filtration device for gearbox gear oil. Background Technology

[0002] Wind farms typically operate in harsh environments, often characterized by strong winds and sandstorms, or by coastal areas with high humidity and salt spray. Long-term operation in such conditions can lead to contamination and deterioration of the gear oil in the gearbox if it is not regularly filtered and regenerated. This contamination results in issues such as excessive particle size, iron content, and acid value; a dark reddish-black color; a foul odor; and the production of large amounts of gummy substances. This deterioration in oil quality causes wear and damage to bearings, gears, and other components within the wind turbine's bearing housing. Examples include severe gear flaking, significant wear on the secondary parallel gear teeth, and broken bearing roller supports. These conditions severely impact the normal operation of wind power generation, increase maintenance costs, and intensify the workload for maintenance workers. The cost of replacing and restoring spare parts for wind turbine generators is substantial; the total cost of replacing a single main shaft can exceed 500,000 yuan.

[0003] Therefore, after long-term research, the inventors proposed an online dedicated process device without affecting the operation of the gearbox. Summary of the Invention

[0025] As shown in Figure 1, the online gear oil filtration device for gearboxes includes a movable support 8. The movable support 8 is equipped with an oil suction filter 2, a motor pump unit 3, a regeneration filter tank 5, a fine filter tank 6, and a control panel 4. The oil inlet of the oil suction filter 2 is connected to the oil outlet of the gearbox via a pipe. The oil outlet of the fine filter tank 6 is connected to the oil inlet of the gearbox via an oil supply pipe. The oil outlet of the regeneration filter tank 5 is connected to the oil inlet of the fine filter tank 6 via an oil pipe. The oil inlet of the motor pump unit 3 is connected to the oil outlet of the oil suction filter 2 via a pipe, and the oil outlet of the motor pump unit 3 is connected to the oil inlet of the regeneration filter tank 5 via a pipe. The control panel 4 is connected to the motor pump unit 3 via a wire and controls the motor. Pump unit 3 is in operation. Control panel 4 is existing technology. Due to its low control requirements, a commercially available microcontroller can be used to control the operation of motor pump unit 3. When motor pump unit 3 is in operation, the gear oil in the gearbox enters the suction filter 2 through the oil pipe for primary filtration. The gear oil after primary filtration is then transported by motor pump unit 3 to the regeneration filter tank 5 for secondary filtration. The gear oil after secondary filtration then passes through the fine filter tank 6 for tertiary filtration. Finally, the filtered gear oil re-enters the gearbox to lubricate the gears, thus enabling the gear oil to be used multiple times, thereby reducing costs. Moreover, the gear oil does not affect the lubrication of the gearbox during the filtration process, realizing online filtration of gear oil.

[0026] In this embodiment, an inlet ball valve 1 is installed on the pipe connecting the oil suction filter 2 and the gearbox, and an outlet ball valve 7 is installed on the pipe connecting the fine filter tank 6 and the gearbox. By adjusting the inlet ball valve 1, the oil inlet flow rate of the oil suction filter 2 can be controlled, and by adjusting the outlet ball valve 7, the oil supply flow rate of the fine filter tank 6 can be controlled. Thus, the size and opening / closing of the inlet ball valve 1 and the outlet ball valve 7 can be reasonably controlled according to the condition of the gear oil in the gearbox. For example, when the gear oil in the gearbox is newly added, there is no need to filter the gear oil. At this time, the inlet ball valve 1 and the outlet ball valve 7 are closed. After the gear oil has been used for a period of time, the inlet ball valve 1 and the outlet ball valve 7 can be kept in a half-open state. After long-term use of the gear oil, the inlet ball valve 1 and the outlet ball valve 7 need to be adjusted to a fully open state to lubricate the gear oil at full power and ensure the normal operation of the gears in the gearbox.

[0027] In this embodiment, the movable support 8 includes a base 11, on which a vertical frame 13 is vertically mounted. The oil suction filter 2, the regeneration filter tank 5, and the fine filter tank 6 are all detachably mounted on the vertical frame 13 via clamps. Furthermore, the vertical frame 13 is provided with several crossbeams, and each crossbeam is provided with a protruding mounting bracket 14. An installation gap is formed between the mounting bracket 14 and the crossbeam. A waist-shaped groove 15 is laterally opened on the front end face of the mounting bracket 14. One end of the clamp is mounted on the mounting bracket 14, and the clamp includes two opposing half-hoops 21. The two ends of the semi-hoop 21 are provided with outwardly folded ears 22. The folded ear 22 at one end of the semi-hoop 21 passes through the waist-shaped groove 15 and enters the installation gap. A limit block 23 is provided on the outside of the folded ear 22 located in the installation gap. The height of the limit block 23 is greater than the height of the waist-shaped groove 15, and the two limit blocks 23 are locked to the two corresponding folded ears 22 by locking bolts 24. The folded ear 22 at the other end of the semi-hoop 21 is locked by fastening bolts 25. Taking the fine filter tank 6 as an example, the oil suction filter 2, the regeneration filter tank 5 and the fine filter tank 6 are explained. The clamp is detachably connected to the movable bracket 8. During installation, the fine filter tank 6 is hoisted to the corresponding position, and then the two half-clamps 21 are brought closer to the fine filter tank 6. The bent lug 22 at one end of the half-clamp 21 is inserted into the installation gap, and then the outer side of the bent lug 22 is fully secured by the limiting block 23. The two limiting blocks 23 and the two corresponding bent lugs 22 are locked together by the locking bolts 24, and the bent lug 22 at the other end of the clamp is locked together by the fastening bolts 25. After the fastening bolts 25 and the locking bolts 24 are locked, the clamp will hold the fine filter tank 6 in place. The clamp is tightened and a limit stop 23 is provided to prevent the clamp from coming off the mounting bracket 14, thus ensuring the reliability of the clamp installation. After long-term use, the clamp can be tightened again by tightening the fastening bolt 25 to ensure the reliability of the clamp holding the fine filter. When the fine filter needs to be replaced, the fastening bolt 25 can be loosened to release the fine filter from the two half clamps 21, and then a new fine filter can be installed. The fastening bolt 25 can then be tightened. In this embodiment, there are at least two clamps, which respectively hold the top and bottom of the fine filter.

[0028] In this embodiment, a collection box 12 is also placed on the base 11. The collection box 12 is located below the regeneration filter tank 5 and the fine filter tank 6. When the regeneration filter tank 5 and the fine filter tank 6 need to be cleaned after long-term use, the waste oil of the regeneration filter tank 5 and the fine filter tank 6 can be directly put into the collection box 12 and then the waste oil is centrally processed.

[0029] In this embodiment, the bottom of the base 11 is provided with a universal wheel with a locking function. The universal wheel with the locking function is the prior art, and its installation method with the base 11 is also the prior art, so it will not be described in detail. After the universal wheel is unlocked, the filter device can be easily moved. Therefore, the filter device can be moved to the vicinity of the gearbox to filter the gear oil according to actual needs.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
