[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and deliver gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas delivery machinery. The fans usually mentioned include ventilators, blowers, and wind turbines. When the gearbox is in use, lubricating oil needs to be added inside the gearbox to lubricate the gears in the gearbox and extend the service life of the gears.

[0027] Reference Figure 1-5 , a wind turbine gearbox oil leakage warning device, comprising a wind turbine gearbox body 1, a protective cover 2 and a warning mechanism;

[0028] The wind turbine gearbox body 1 includes a gearbox 1 101 and a gearbox 2 102. One side of the gearbox 101 is sealed and connected to the gearbox 2 102. The sealing sleeve of the gearbox 101 and the gearbox protective sleeve 2 is arranged at the connection between the gearbox 101 and the gearbox 2 102. The early warning mechanism is arranged on the protective sleeve 2.

[0029] The early warning mechanism includes a sealing ring 3, a sleeve 4, a telescopic rod 5, an arc plate 6, a spring 7 and a sensor 8. The sealing ring 3 is slidably connected in the protective sleeve 2, and the sealing ring 3 is sleeved at the connection between the gear box 1 101 and the gear box 2 102. Through the coordinated design of the fan gear box body 1, the protective sleeve 2, the early warning mechanism and the air pipe 10, not only can the effect of oil leakage early warning of the fan gear box body 1 be achieved, but also the effect of sealing the oil leakage point can be achieved to prevent excessive leakage of lubricating oil, and the simple structure improves convenience and practicality.

[0030] In this embodiment, four sleeves 4 are fixedly installed in the protective sleeve 2, and telescopic rods 5 are slidably connected in the four sleeves 4. One end of the four telescopic rods 5 is fixedly connected to an arc plate 6, which is used to stabilize the four arc plates 6 in the protective sleeve 2. The four arc plates 6 are all in contact with the sealing ring 3, which is used to limit the sealing ring 3 and balance the force on the sealing ring 3.

[0031] In this embodiment, the sensor 8 is fixedly installed in the protective cover 2 and corresponds to one of the four arc plates 6 .

[0032] In this embodiment, a button is provided on the sensor 8 , and a fixing rod 9 is fixedly mounted on one of the four arc plates 6 , and the fixing rod 9 abuts against the button to facilitate triggering the sensing system in the sensor 8 .

[0033] In this embodiment, springs 7 are respectively provided on the four sleeves 4, one ends of the four springs 7 are fixedly connected to the protective sleeve 2, and the other ends of the four springs 7 are respectively fixedly connected to the four arc plates 6. The four arc plates 6 are restored to their original state through the action of the four springs 7, and the sealing ring 3 is further tightly fitted with the connection between the gear box 1 101 and the gear box 2 102.

[0034] In this embodiment, a mounting hole is opened on the gear box 102, and an air pipe 10 is sealed in the mounting hole. The air pipe 10 is provided with a valve 11 to facilitate the delivery of gas between the sealing ring 3 and the gear box 1 101 and the gear box 2 102.

[0035] In this embodiment, the sealing ring 3 has a certain elasticity.

[0036] In this embodiment, the sensor 8 is connected to an external alarm system to facilitate notifying the staff to deal with the oil leakage problem and avoid accidents.

[0037] Working principle: When in use, firstly, the protective sleeve 2 and the sealing ring 3 are sleeved on the connection between the gear box 1 101 and the gear box 2 102, and then, the gas is transported between the sealing ring 3 and the gear box 1 101 and the gear box 2 102 through the action of the air pipe 10 and the mounting holes on the gear box 2 102, so that the sealing ring 3 expands and the distance between the gear box 1 101 and the gear box 2 102 bracket increases, and then the valve 11 on the air pipe 10 is closed. In this process, the sealing ring 3 acts on the four arc plates 6 so that the four arc plates 6 are driven by the four telescopic rods 5 to slide in the sleeve 4, and the four springs 7 are compressed respectively, and at the same time, one of the four arc plates 6 drives the fixed rod 9 to move synchronously, and one end of the fixed rod 9 presses the button on the sensor 8, so as to achieve the purpose of installing the fan gearbox oil leakage warning device;

[0038] When leakage occurs at the connection between the gear box 1 101 and the gear box 2 102, since there is gas between the sealing ring 3 and the gear box 1 101 and the gear box 2 102, the gas enters the fan gear box body 1 through the leakage, thereby achieving the effect of pressure relief. At the same time, the sealing ring 3 shrinks and is sleeved on the connection between the gear box 1 101 and the gear box 2 102, thereby achieving the effect of sealing the leakage.

[0039] While the sealing ring 3 contracts, the four arc plates 6 are restored to their original states through the forces of the four springs 7. During this process, one of the four arc plates 6 drives the fixing rod 9 to move synchronously and causes the fixing rod 9 to disengage from the button on the sensor 8, thereby triggering the sensing system of the sensor 8, causing the external alarm system to issue an alarm notification, thereby achieving the effect of oil leakage early warning.

[0040] The technical progress achieved by the utility model compared with the prior art is that through the cooperation of various components, not only can the oil leakage warning effect of the fan gearbox main body 1 be achieved, but also the oil leakage point can be sealed to prevent excessive leakage of lubricating oil, and the simple structure improves convenience and practicality.
