Description

Technical Field

[0001] This utility model relates to the field of pitch motor technology, specifically to an oil leak-proof cover. Background Technology

[0002] A pitch motor is a drive device in a wind turbine generator set used to dynamically adjust the blade pitch angle. Its core function is to achieve precise control of wind energy capture efficiency and unit safety by changing the blade pitch angle. It connects to the main control system through slip rings or wireless communication and receives feedback parameters from sensors such as wind speed and rotational speed in real time.

[0003] Existing pitch motors still have certain shortcomings in actual use: the output shaft of existing pitch motors lacks a structure to prevent oil leakage, which causes the lubricating oil at the bearing to be thrown out from the gap between the output shaft and the motor housing when the output shaft rotates, resulting in pollution of the external environment. Based on the shortcomings of existing technology, this utility model designs an oil leakage prevention cover. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This type of oil leak-proof cover, through the oil leak-proof structure, when the oil leak-proof structure is fixed on the pitch motor, by putting the magnetic suction ring on the outside of the output shaft and adsorbing it on the outer surface of the motor, at this time, by turning the throttle, the output shaft can be rotated. Due to the limiting of the two side limit rods, the threaded rod can push the mounting base to move and clamp the output shaft. Thus, the rotation of the output shaft is not hindered when the motor is working. At the same time, due to the setting of the conical ring, the lubricating oil can be kept inside the magnetic suction ring, thus preventing the lubricating oil inside the motor from being thrown out from the through hole, thereby achieving the purpose of preventing oil leakage from the pitch motor.

[0015] 2. This type of oil leak-proof cover, through its collection structure, allows the lubricating oil inside the magnetic collar to enter the collection tank through the oil leakage hole when there is oil leakage at the output shaft. The lubricating oil inside the collection tank can be observed through the transparent window and scale lines. After a certain amount has been collected, the lubricating oil inside the collection tank can be taken out and reused. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 An oil leak-proof cover includes an oil leak-proof structure 1 installed on the outer surface of a pitch motor. The oil leak-proof structure 1 includes a magnetic collar 101 and a metal sealing gasket 102. A conical ring 111 is fixedly installed on the inner wall of the magnetic collar 101. Two fixing seats 105 are fixedly installed on one side of the outer surface of the magnetic collar 101. A through hole 104 is opened inside the magnetic collar 101. Threaded rods 106 are rotatably installed inside the two fixing seats 105. A throttle 107 is fixedly installed on one side of the two threaded rods 106. Mounting seats 108 are rotatably installed on the other end of the two threaded rods 106. Clamping wheels 110 are rotatably installed inside the two mounting seats 108. Two limiting rods 109 are fixedly installed on one side of the two mounting seats 108. The two limiting rods 109 are movably connected to the fixing seats 105.

[0024] Please see Figure 1-2 The metal sealing gasket 102 can be fitted over the magnetic collar 101. The internal threads of the metal sealing gasket 102 are fitted with four fixing bolts 103, which are threadedly connected to the pitch motor.

[0025] By fitting a metal sealing gasket 102 over the magnetic collar 101 and securing it with fixing bolts 103, lubricating oil can be prevented from leaking out of the gap between the magnetic collar 101 and the pitch motor.

[0026] Please see Figure 4-5The magnetic collar 101 has an oil leakage hole 112 inside. A collection structure 2 is fixedly installed on one side of the outer surface of the magnetic collar 101. The collection structure 2 includes a connecting pipe 21. The connecting pipe 21 communicates with the oil leakage hole 112. A collection hose 22 is fixedly installed at one end of the connecting pipe 21, and a collection tank 23 is threadedly installed at one end of the collection hose 22. A transparent window 24 is fixedly installed on the outer surface of the collection tank 23. A scale line 25 is opened on one side of the outer surface of the collection tank 23, and the scale line 25 is opened on one side of the transparent window 24.

[0027] When there is oil leakage at the output shaft, the oil leakage hole 112 allows the lubricating oil inside the magnetic collar 101 to enter the collection tank 23 through the collection hose 22 for collection. The lubricating oil inside the collection tank 23 can be observed through the transparent window 24 and the scale line 25. After a certain amount has been collected, the lubricating oil inside the collection tank 23 can be taken out and reused.

[0028] Working principle: When using an oil leak preventer, firstly, the magnetic collar 101 is placed around the output shaft and adheres to the outer surface of the motor. Then, a metal sealing gasket 102 is placed over the magnetic collar 101 and secured with fixing bolts 103. This prevents lubricating oil from leaking out of the gap between the magnetic collar 101 and the pitch motor. Then, by rotating the throttle 107, the limiting rods 109 on both sides cause the threaded rod 106 to push the mounting base 108 to move and clamp the output shaft, thus preventing oil leakage during motor operation. The output shaft rotation is hindered. At the same time, due to the setting of the conical ring 111, the lubricating oil can stay inside the magnetic collar 101, thus preventing the lubricating oil inside the motor from being thrown out from the through hole 104. Finally, when there is oil leakage at the output shaft, the lubricating oil inside the magnetic collar 101 can be collected in the collection tank 23 through the collection hose 22 by the setting of the oil leakage hole 112. The lubricating oil inside the collection tank 23 can be observed through the transparent window 24 and the scale line 25. After a certain amount is collected, the lubricating oil inside the collection tank 23 can be taken out and reused.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
