Detailed Implementation

[0034] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0035] Secondly, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] Furthermore, it should be noted that in the description of this application, the terms "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0038] As shown in the background section, in the prior art, oil leaks are prone to occur at the high-speed shaft output end, tube shaft output end, and pipeline connection of the wind turbine gearbox. Furthermore, the wind turbine gearbox is relatively large, and a single oil collection box cannot collect the oil leaking from all the oil leak points of the wind turbine gearbox. Therefore, oil collection boxes are installed below each oil leak point, and each oil collection box is connected to the rear base of the wind turbine gearbox in sequence by multiple screws. Each oil collection box is used to collect the oil leaking from each oil leak point.

[0039] However, the above-mentioned method of installing the oil collection box is inconvenient and has low installation efficiency.

[0040] Based on this, the oil receiving structure and wind turbine generator set provided in this application have an oil receiving structure consisting of at least two support members and multiple oil receiving components. The support members are spaced apart and connected to the rear base frame of the wind turbine gearbox, thereby securing the support members. Two adjacent support members can jointly support multiple oil receiving components. The opposite sides of each oil receiving component rest on two adjacent support members, and adjacent oil receiving components overlap to form an oil flow channel. The oil receiving components are easy to install. The oil receiving structure and wind turbine generator set provided in this application have an easy-to-install oil receiving structure, improving the installation efficiency of the oil receiving structure.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] Figure 1 This is a schematic diagram of the oil receiving structure provided in an embodiment of this application.

[0043] Reference Figure 1 As shown, in a first aspect, this application provides an oil receiving structure, including: at least two support members 100 and a plurality of oil receiving members 200, wherein each support member 100 is spaced apart, and the support member 100 is used to connect to the rear base frame of a wind turbine gearbox.

[0044] The oil receiving parts 200 are respectively mounted on two adjacent support members 100 on opposite sides, and the two adjacent oil receiving parts 200 overlap to form an oil flow channel.

[0045] It should be noted that the rear base frame is the support for the wind turbine gearbox. The rear base frame is located below the wind turbine gearbox. The support member 100 is used to connect to the rear base frame of the wind turbine gearbox. Thus, the support member 100 and the oil receiving member 200 attached to the support member 100 are both located below the wind turbine gearbox. The oil receiving member 200 can collect the oil leaking from various oil leakage points on the wind turbine gearbox.

[0046] For example, the support member 100 can be connected to the rear base frame of the wind turbine gearbox by bolts, welding, or other means. This application embodiment does not impose too many restrictions on the connection method between the support member 100 and the rear base frame.

[0047] For example, the number of support members 100 can be two, three, or more than three. The number of support members 100 can be determined according to the size of the oil receiving member 200 and the wind turbine gearbox. As long as each oil receiving member 200 overlapping the support member 100 can cover the oil leakage area of ​​the wind turbine gearbox, this application embodiment does not impose too many restrictions on this.

[0048] Thus, by connecting the support member 100 to the rear base frame of the wind turbine gearbox, the support member 100 can be fixed, thereby allowing the oil receiving component 200 to be erected on two adjacent support members 100, with the support member 100 providing support for the oil receiving component 200. Since two adjacent support members 100 can jointly support multiple oil receiving components 200, and the oil receiving components 200 are erected on two adjacent support members 100 with adjacent components overlapping each other, compared to the prior art where each oil receiving box is sequentially connected to the rear base frame of the wind turbine gearbox with multiple screws, the installation of the oil receiving component 200 is more convenient, improving the installation efficiency of the oil receiving structure.

[0049] It should be noted that two adjacent oil receiving parts 200 overlap to form an oil flow channel. The oil flow channel can be used to collect oil, avoid secondary oil leakage, and ensure the oil receiving effect of the oil receiving structure.

[0050] It should also be noted that existing oil collection boxes are used to collect locally leaked oil from leak points. Due to the limited size of the oil collection box, the oil collection range is limited, resulting in poor oil collection effectiveness. The oil collection structure provided in this application embodiment allows two adjacent support members 100 to overlap with multiple oil collection members 200, and two adjacent oil collection members 200 overlap to form an oil flow channel. The continuous oil flow channel expands the oil collection range and improves the oil collection effectiveness of the oil collection structure.

[0051] Figure 2 for Figure 1 Schematic diagram of the structure of the intermediate oil connection part 200 Figure 1 .

[0052] In some embodiments, refer to Figure 1 and Figure 2 As shown, the oil receiving member 200 includes an oil receiving part 210 and overlapping parts 220 disposed on both sides of the oil receiving part 210. The overlapping parts 220 overlap on the support member 100.

[0053] The oil receiving part 210 bends toward the support member 100, and the oil receiving parts 210 located on the same side of the same support member 100 overlap sequentially along the extension direction of the support member 100.

[0054] Specifically, the oil receiving part 200 overlaps the support part 100 through the overlapping part 220. No complicated tools or equipment are required. Simply place the overlapping part 220 on the support part 100. The operation is convenient, which improves the installation efficiency of the oil receiving part 200 and saves time and labor costs.

[0055] In practical implementation, the overlapping portions 220 on the same side of the same support member 100 can overlap sequentially along the extension direction of the support member 100, which can guide the oil from one of the two adjacent overlapping portions 220 to the other, avoid the oil from leaking from the joint of the two adjacent overlapping portions 220, and improve the reliability of the oil receiving structure.

[0056] For example, the overlapping portion 220 can be a plane. The planar overlapping portion 220 overlaps the support member 100, which can increase the contact area between the overlapping portion 220 and the support member 100, thereby improving the strength and stability of the overlapping portion.

[0057] Understandably, the support member 100 is located below the wind turbine gearbox, and the oil receiving member 200 overlaps the support member 100 through the overlapping part 220. The oil receiving part 210 of the oil receiving member 200 is bent toward the support member 100, that is, the oil receiving part 210 is bent away from the wind turbine gearbox. In this way, the capacity of the oil receiving part 210 can be increased.

[0058] It should be noted that the bending of the oil receiving part 210 toward the support member 100 can reduce the possibility of oil splashing out from the oil receiving part 210, improve the oil receiving effect of the oil receiving part 210, and thus improve the reliability of the oil receiving member 200.

[0059] For example, the overlap 220 can be arc-shaped. The bottom of the arc-shaped overlap 220 has no sharp edges, and the oil can naturally slide to the lowest point by gravity, which improves the oil collection efficiency and reduces the possibility of oil accumulation at the corners, making it easier to clean and maintain.

[0060] It should also be noted that the oil receiving parts 210 located on the same side of the same support member 100 overlap sequentially along the extension direction of the support member 100, which can guide the oil from one of the two adjacent oil receiving parts 210 to the other, avoid the oil from leaking from the joint of the two adjacent oil receiving parts 210, and improve the reliability of the oil receiving structure.

[0061] In some embodiments, refer to Figure 1 and Figure 2 As shown, the width of the support member 100 is less than twice the width of the overlap 220.

[0062] It should be noted that the width of the overlap 220 is... Figure 2 The length of L1, indicated by the middle arrow, and the width of support member 100 are... Figure 4The length of L2 indicated by the middle arrow and the width of the support member 100 being less than twice the width of the overlap 220 allow the overlaps 220 of the oil receiving members 200 respectively placed on both sides of the support member 100 to at least partially overlap. This enables the oil to flow from one of the two adjacent overlaps 220 to the other, preventing oil leakage from the gap between the two adjacent overlaps 220 and improving the reliability of the oil receiving structure.

[0063] In some embodiments, refer to Figure 1 and Figure 2 As shown, the width of the overlapping part 220 is equal to the width of the support member 100.

[0064] The overlapping portion 220 has a flange 221 on the side away from the oil receiving portion 210, and the flange 221 is inclined toward the support member 100.

[0065] It should be noted that the width of the overlapping portion 220 is equal to the width of the support member 100, which allows the overlapping portions 220 of the oil receiving members 200 respectively laid on both sides of the support member 100 to completely overlap, and the opposite sides of the overlapping portion 220 are flush with the support member 100. Thus, by providing a flange 221 on one side of the overlapping portion 220, with the flange 221 inclined towards the support member 100, the connection strength between the overlapping portion 220 and the support member 100 can be improved, making it difficult for the overlapping portion 220 and the support member 100 to separate.

[0066] It should also be noted that the bending radius of the flange 221 can be consistent with the bending radius of the oil receiving part 210, so that the oil receiving part 210 of one of the oil receiving parts 200 respectively erected on both sides of the support member 100 fits with the flange 221 of the other, which can reduce local stress concentration and thus reduce the risk of material fatigue and damage.

[0067] Figure 3 for Figure 1 Schematic diagram of the structure of the intermediate oil connection part 200 Figure 2 .

[0068] In some embodiments, refer to Figure 3 As shown, the end of the oil flow channel is provided with a stop 211, and the top of the stop 211 is flush with the overlapping part 220.

[0069] Understandably, by providing a stop 211 at the end of the oil flow channel, secondary leakage of the oil collected in the oil flow channel can be prevented, thus ensuring the reliability of the oil receiving part 200.

[0070] Specifically, the top of the stop 211 is flush with the overlap 220, which maximizes the capacity of the oil flow channel, reduces the possibility of secondary oil leakage, reduces the need for frequent cleaning or replacement of the oil receiving part 200, and reduces the time for manual intervention.

[0071] In some embodiments, refer to Figure 1 and Figure 2 As shown, the oil receiving component 200 is provided with a first insertion part 201 and a second insertion part 202, and two adjacent oil receiving components 200 are connected to each other through the first insertion part 201 of one and the second insertion part 202 of the other.

[0072] Understandably, the connection between two adjacent oil receiving parts 200 is improved by connecting the first insertion part 201 of one to the second insertion part 202 of the other through the first insertion part 201 of the other. This prevents the two adjacent oil receiving parts 200 from displacing relative to each other, ensures that the edges of the two adjacent oil receiving parts 200 can remain overlapping, and avoids oil leakage from the joint.

[0073] It should be noted that the first insertion part 201 and the second insertion part 202 can both be provided on the overlapping part 220 of the oil receiving member 200; or they can both be provided on the oil receiving part 210 of the oil receiving member 200. As long as the first insertion part 201 and the second insertion part 202 do not affect the oil receiving member 200 from collecting oil and the oil receiving member 200 does not leak, this application embodiment does not impose too many restrictions on this.

[0074] Specifically, by inserting the plug into the plug hole, the connection between two adjacent oil connection parts 200 can be quickly achieved, which is convenient and improves installation efficiency.

[0075] In some embodiments, one of the first plug-in portion 201 and the second plug-in portion 202 may be a plug hole, and the other may be a plug post that can be plugged into the plug hole.

[0076] For example, the plug can be disposed on the side of the oil receiving member 200 away from the support member 100, so that the part of the oil receiving member 200 with the plug hole is pressed on top of the oil receiving member 200 with the plug, thereby realizing the plug and the plug hole can be plugged in.

[0077] For example, the plug can be provided on the side of the oil receiving member 200 facing the support member 100, so that the part of the oil receiving member 200 with the plug can be pressed on top of the oil receiving member 200 with the plug hole, thereby realizing the plug and the plug hole can be plugged in.

[0078] In some embodiments, one of the first insertion portion 201 and the second insertion portion 202 may be a groove, and the other may be a protrusion that can be inserted into the groove.

[0079] Figure 4 for Figure 1 A schematic diagram of the structure of the middle support member 100.

[0080] In some embodiments, refer to Figure 1 and Figure 4As shown, both ends of the support member 100 are provided with mounting parts 110, which are used to connect to the rear base frame of the wind turbine gearbox.

[0081] Understandably, mounting portions 110 are provided at both ends of the support member 100. The mounting portions 110 provide mounting positions for the support member 100, and the support member 100 can be connected to the rear base frame of the wind turbine gearbox through the mounting portions 110.

[0082] In a specific implementation, the support member 100 has a first support surface 120 and a second support surface 130 located on both sides of the first support surface 120. The first support surface 120 is used to overlap the oil receiving member 200, and the second support surface 130 is used to connect with the mounting part 110.

[0083] For example, the first end of the mounting part 110 can be connected to the second support surface 130 by welding or bolting, and the second end of the mounting part 110 can be connected to the rear base frame of the wind turbine gearbox by welding or bolting. This application embodiment does not impose too many restrictions on this.

[0084] Specifically, the second end of the mounting part 110 can be provided with a mounting surface 111, which can be horizontally set. The mounting surface 111 is provided with multiple through holes, and bolts are connected to the rear base frame of the wind turbine gearbox through the through holes.

[0085] In some embodiments, refer to Figure 1 As shown, the oil receiving structure also includes an oil collecting component 300, which is connected to at least one support component 100 and is connected to the oil flow channel.

[0086] Specifically, by setting up an oil collecting component 300, the oil collecting component 300 can collect the oil in the oil receiving component 200 in a concentrated manner, which is convenient for regular cleaning and maintenance.

[0087] In some embodiments, refer to Figure 1 As shown, the oil collecting component 300 is provided with a connecting pipe 310, and the oil collecting component 300 is connected to the oil flow channel through the connecting pipe 310.

[0088] In a specific implementation, the oil collecting component 300 can be an oil collecting tank or an oil collecting bucket. A connecting pipe 310 can be installed on the oil collecting tank or oil collecting bucket, and an oil drain port 212 (or an oil drain steel pipe) can be installed on the oil flow channel. The connecting pipe 310 is connected to the oil drain port 212 (or oil drain steel pipe), and the oil in the oil flow channel can be discharged into the oil collecting tank or oil collecting bucket in sequence through the oil drain port 212 and the connecting pipe 310. For example, the oil drain port 212 can be located at one end of the oil flow channel near the oil collecting component 300.

[0089] For example, the connecting pipe 310 can be a flexible hose.

[0090] It should be noted that the support member 100 can be inclined so that the height of the end of the support member 100 with the oil collecting member 300 is lower than the height of the other end of the support member 100. This allows the oil in the oil flow channel to flow from high to low, improving the oil collecting efficiency of the oil collecting member 300. In specific implementation, the height of the two ends of the support member 100 can be controlled by changing the length of the mounting portions 110 at both ends of the support member 100.

[0091] Secondly, this application provides a wind turbine generator set, including a wind turbine generator set body and an oil receiving structure disposed on the wind turbine generator set.

[0092] The specific structure and working method of the oil receiving structure have been described in detail in the above embodiments, and will not be repeated here.

[0093] Those skilled in the art will understand that the oil receiving structure and wind turbine generator set provided in this application, wherein the oil receiving structure comprises at least two support members 100 and multiple oil receiving parts 200, with each support member 100 spaced apart. The support members 100 are used to connect to the rear base frame of the wind turbine gearbox, thereby fixing the support members 100. Two adjacent support members 100 can jointly support multiple oil receiving parts 200. The opposite sides of each oil receiving part 200 are respectively mounted on two adjacent support members 100, and two adjacent oil receiving parts 200 overlap to jointly form an oil flow channel. The oil receiving parts 200 are easy to install. The oil receiving structure and wind turbine generator set provided in this application embodiment are easy to install, improving the installation efficiency of the oil receiving structure.
