Technical Field

[0001] The embodiments of the present application relate to the technical field of power equipment, and in particular, to an oil collecting device and a wind turbine generator. Background Art

[0002] A wind turbine generator is the main equipment for wind power generation. The pitch system of a wind turbine generator usually uses lubricating oil for lubrication, and multiple oil collecting bottles are usually arranged on the pitch bearing. The waste oil produced by the pitch bearing will enter the oil collecting bottles through the drain pipe, and the waste oil will be transported to the bottom of the oil collecting bottles through the drain pipe.

[0003] In the existing pitch oil collecting system of a wind turbine generator, due to the operating characteristics of the pitch, the waste oil discharge is concentrated in one or two bottles, and there is no waste oil discharge in the oil collecting bottles at other positions. Therefore, the bottles with concentrated waste oil are prone to fall off, resulting in more oil stains on the hub cover, which not only affects the beauty of the wind turbine, but also poses a safety hazard of causing the operators to slip.

[0031] Therefore, referring to Figures 1 to 3 , an oil collecting device 100 is provided in an embodiment of this application. The oil collecting device 100 is arranged on the hub cover of a wind turbine. The oil collecting device 100 includes a connection part 101 and an oil collecting pipe 102. The connection part 101 is arranged at the oil outlet of the hub cover of the wind turbine, and the oil collecting pipe 102 is connected to the connection part 101 to collect the waste oil flowing out of the connection part 101.

[0032] Compared with the existing oil collecting system, in the oil collecting device 100 provided in the embodiment of this application, the oil collecting bottle is replaced by the oil collecting pipe 102. The waste oil discharged from the oil outlet of the hub cover of the wind turbine can flow into the oil collecting pipe 102 through the connection part 101. The oil collecting pipe 102 can provide sufficient accommodation space for the waste oil to prevent the waste oil from leaking out. When it is necessary to clean the waste oil, only the oil collecting pipe 102 needs to be removed and cleaned. Therefore, the oil collecting device 100 provided in the embodiment of this application has a simple structure, is convenient to install and easy to clean.

[0033] Furthermore, referring to Figure 2 and Figure 5 , in some embodiments of this application, the oil collecting device 100 further includes a three-way joint seat 103. The oil collecting pipe 102 is communicated with the connection part 101 through the three-way joint seat 103. The function of the three-way joint seat 103 is to connect the oil collecting pipe 102 and the connection part 101, so as to ensure the stable connection between the oil collecting pipe 102 and the connection part 101, thus facilitating the collection of waste oil and preventing the waste oil from leaking out.

[0034] Furthermore, referring to Figure 4 , in some embodiments of this application, the connection part 101 includes a stud 111, a boss 112 and a connector 113. The stud 111 is fixedly connected to the oil outlet of the hub cover of the wind turbine. The boss 112 is arranged between the stud 111 and the connector 113. The connector 113 is connected to the oil collecting pipe 102 through the three-way joint seat 103. The boss 112 is arranged between the stud 111 and the connector 113.

[0035] Specifically, the stud 111 of the connection head 101 is fixedly connected to the oil outlet of the hub cover of the wind turbine. The boss 112 of the connection head 101 is arranged between the stud 111 and the connector 113. The function of the boss 112 is to abut against the three-way joint seat 103. The connector 113 of the connection head 101 is connected to the oil collecting pipe 102 through the three-way joint seat 103, so as to further ensure the stable connection between the oil collecting pipe 102 and the connection head 101, thus facilitating the collection of waste oil and preventing the leakage of waste oil.

[0036] Further, referring again to Figure 4 , in some embodiments of the present application, the diameter of the boss 112 is greater than the diameter of the stud 111 and / or the connector 113. The function of the boss 112 of the connection head 101 is to allow an external force to be applied to its outer surface, so that the stud 111 of the connection head 101 is tightly connected to the oil outlet of the hub cover of the wind turbine, so as to further ensure the stable connection between the oil collecting pipe 102 and the connection head 101, thus facilitating the collection of waste oil and preventing the leakage of waste oil.

[0037] Further, referring to Figure 5 , in some embodiments of the present application, the three-way joint seat 103 includes a laterally extending portion 131 and a joint connecting portion 132 connected to each other, wherein the extending direction of the joint connecting portion 132 is perpendicular to the extending direction of the laterally extending portion 131. The laterally extending portion 131 is arranged inside the oil collecting pipe 102, and the joint connecting portion 132 is in communication with the connection head 101. The laterally extending portion 131 of the three-way joint seat 103 is arranged inside the oil collecting pipe 102, and the joint connecting portion 132 is in communication with the connection head 101 to ensure the stable connection between the oil collecting pipe 102 and the connection head 101, thus facilitating the collection of waste oil and preventing the leakage of waste oil.

[0038] Further, as Figure 5 shown, in some embodiments of the present application, the laterally extending portion 131 is a hollow structure, and the laterally extending portion 131 is provided with an installation port. The joint connecting portion 132 is connected to the laterally extending portion 131 through the installation port. Therefore, after the waste oil is discharged from the oil outlet of the hub cover of the wind turbine, it can flow into the laterally extending portion 131 through the joint connecting portion 132 and is finally collected by the oil collecting channel 102. The oil collecting pipe 102 can provide enough accommodation space for the waste oil to prevent the leakage of waste oil.

[0039] Furthermore, in some embodiments of the present application, the lateral extension portion 131 is sleeved inside the oil collecting pipe 102 by interference fit, and the connector 113 of the connector portion 101 is sleeved inside the connector connecting portion 132 of the tee joint seat 103 by interference fit. Therefore, with the above arrangement, the oil collecting device 100 provided by the embodiments of the present application can prevent waste oil from leaking out, so as to avoid production accidents and not affect the appearance of the wind turbine.

[0040] Furthermore, in some embodiments of the present application, the number of the connector portions 101 is multiple, and the multiple connector portions 101 are evenly distributed on the hub cover of the wind turbine, and the oil collecting pipe 102 extends on the outer surface of the hub cover of the wind turbine. Therefore, after the waste oil is discharged from the oil outlet of the hub cover of the wind turbine, it can flow into the oil collecting channel 102 through the multiple connector portions 101 for collection, and the oil collecting pipe 102 can provide sufficient accommodation space for the waste oil, so as to ensure that all the generated waste oil can flow into the oil collecting pipe 102 to further prevent the waste oil from leaking out.

[0041] Furthermore, referring to Figure 3 , in some embodiments of the present application, the oil collecting device 100 further includes an end cap 104, the end cap 104 is arranged at the end of the oil collecting pipe 102, and the end cap 104 covers the lateral extension portion 131 of the tee joint seat 103.

[0042] Specifically, the function of the end cap 104 is to block the oil collecting pipe 102 at the end position, so as to prevent waste oil from leaking out. The end cap 104 covers the lateral extension portion 131 of the tee joint seat 103 to ensure that the end cap 104 can be stably installed at the end of the oil collecting pipe 102, so as to ensure the stable operation of the oil collecting device 100.

[0043] In a second aspect, an embodiment of the present application further provides a wind turbine, including the oil collecting device 100 as described in any one of the above.
