These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0053] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0054] As shown in the background technology, in the prior art, an oil collecting bottle is installed on the variable pitch bearing of the wind turbine generator set and connected to the oil drain port of the variable pitch bearing to collect waste oil. The staff needs to regularly inspect the oil collecting bottle. When the waste oil is full, the oil collecting bottle is removed and cleaned, and then reinstalled on the oil drain port. However, when the oil collecting bottle is removed for cleaning, the oil drain port is exposed, and the waste oil may overflow from the oil drain port due to excessive oil discharge. Or if the staff fails to clean and install a clean oil collecting bottle in time, the waste oil generated after the oil collecting bottle is full will flow out of the oil drain port, and may even spill on the electrical equipment of the wind turbine generator set, affecting its normal operation.

[0055] In response to the above technical problems, an embodiment of the present application provides an oil collecting device, including a first oil bottle, a second oil bottle, a partition assembly, a pressure sensor and a controller. The first oil bottle is connected to the oil drain port, the partition assembly is arranged in the first oil bottle to divide the first oil bottle into an oil collecting chamber and an oil guiding chamber, the second oil bottle is detachably connected to the first oil bottle, the oil collecting chamber is connected to the oil drain port, the oil guiding chamber is connected to the second oil bottle, and the oil guiding chamber is arranged between the oil collecting chamber and the second oil bottle. The controller connects or separates the oil guiding chamber and the oil collecting chamber by controlling the opening and closing of the partition assembly. A pressure sensor is arranged in the oil collecting chamber to detect the pressure of the waste oil on the partition component, so as to determine the waste oil content in the oil collecting chamber. When the pressure is greater than or equal to a first preset value, it proves that the waste oil in the oil collecting chamber is about to be full, and the controller controls the partition component to open to allow the waste oil to flow into the second oil bottle. When the pressure is less than the second preset value, it proves that the waste oil has basically flowed into the second oil bottle, and the controller controls the partition component to close, so that the oil collecting chamber can continue to collect oil. In this way, when the staff cleans the waste oil, they only need to remove the second oil bottle, clean it, and then install it on the first oil bottle. During the cleaning process, the waste oil flowing out of the oil drain port flows into the oil collecting chamber, which effectively prevents the waste oil from overflowing.

[0056] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0057] It should be noted that the oil collection device provided in the embodiment of the present application can be applied to various wind turbine generator sets.

[0058] See also Figure 1 and Figure 4 As shown, the oil collecting device 100 of the embodiment of the present application is used to collect waste oil from the oil discharge port of a component, and includes a first oil bottle 110, a second oil bottle 120, a partition assembly 130, a pressure sensor (not shown in the figure) and a controller (not shown in the figure); the first oil bottle 110 is used to be connected to the oil discharge port, and the second oil bottle 120 is detachably connected to the first oil bottle 110; the partition assembly 130 is arranged in the first oil bottle 110 to separate the first oil bottle 110 into an oil collecting chamber 111 and an oil guiding chamber 112, and the oil guiding chamber 11 2 is located between the oil collecting chamber 111 and the second oil bottle 120; the pressure sensor is arranged in the oil collecting chamber 111, and is used to detect the pressure of the waste oil in the oil collecting chamber 111 on the partition assembly 130, and the partition assembly 130 and the pressure sensor are both electrically connected to the controller; the controller is configured to, when the pressure is greater than or equal to a first preset value, control the partition assembly 130 to open, so that the waste oil flows from the oil collecting chamber 111 into the second oil bottle 120 through the oil guide chamber 112; when the pressure is less than the second preset value, control the partition assembly 130 to close.

[0059] In the embodiment of the present application, the first oil bottle 110 is connected to the oil discharge port, the partition assembly 130 is arranged in the first oil bottle 110, and the first oil bottle 110 is divided into an oil collecting chamber 111 and an oil guiding chamber 112. The controller is electrically connected to the partition assembly 130, and the controller controls the partition assembly 130 to open or close so that the oil collecting chamber 111 and the oil guiding chamber 112 are connected or separated. The second oil bottle 120 is detachably connected to the first oil bottle 110, and the second oil bottle 120 is connected to the oil guiding chamber 112, and the oil guiding chamber 112 is located between the oil collecting chamber 111 and the second oil bottle 120. The pressure sensor is arranged in the oil collecting chamber 111 to detect the pressure of the waste oil in the oil collecting chamber 111 on the partition assembly 130, and transmit the pressure signal to the controller.

[0060] During actual use, the oil collecting chamber 111 is connected to the oil drain port, and the partition assembly 130 is closed. The waste oil flows into the oil collecting chamber 111 from the oil drain port and is collected by the oil collecting chamber 111. When the pressure detected by the pressure sensor is greater than or equal to the first preset value, it proves that the waste oil in the oil collecting chamber 111 is about to be full. The controller controls the partition assembly 130 to open, and the waste oil in the oil collecting chamber 111 flows into the second oil bottle 120 through the oil guide chamber 112. When the detected pressure is less than the second preset value, it proves that the waste oil in the oil collecting chamber 111 has been basically drained and flows into the second oil bottle 120. The controller controls the partition assembly 130 to close, and the oil collecting chamber 111 continues to collect the waste oil flowing out of the oil drain port.

[0061] In this way, when the staff inspects, as long as they find waste oil in the second oil bottle 120, they can remove the second oil bottle 120 for cleaning, without having to judge whether the waste oil is about to be full, to prevent untimely cleaning due to misjudgment. After removing the second oil bottle 120, clean the waste oil in the second oil bottle 120 and install it on the first oil bottle 110. During the cleaning process of the second oil bottle 120, the partition assembly 130 is always closed, and the oil collecting chamber 111 can continue to collect waste oil, to prevent the waste oil in the oil outlet from overflowing and spilling on the wind turbine generator set.

[0062] In addition, after the waste oil flows into the second oil bottle 120 from the oil collecting chamber 111, even if the staff does not find it in time, the oil collecting chamber 111 can continue to collect the waste oil, which effectively prevents the waste oil from overflowing due to untimely cleaning.

[0063] In some possible implementations, see Figure 1 As shown, the partition assembly 130 of the embodiment of the present application includes at least one driving member 131 and at least one partition plate 132; the partition plate 132 is rotatably connected to the inner wall of the first oil bottle 110, the driving member 131 is connected to the partition plate 132 in a one-to-one correspondence, and the driving member 131 is electrically connected to the controller; the controller controls the driving member 131 to drive the partition plate 132 to rotate relative to the first oil bottle 110, so that the oil collecting chamber 111 and the oil guiding chamber 112 are connected or separated.

[0064] In a specific implementation, the driving member 131 drives the partition plate 132 to rotate relative to the inner wall of the first oil bottle 110 to achieve the connection or separation of the oil collecting chamber 111 and the oil guiding chamber 112. The controller controls the driving member 131 to drive the partition plate 132 to rotate according to the detection result of the pressure sensor.

[0065] The number of the partition plate 132 and the number of the driving member 131 are both one. At this time, the shape of the partition plate 132 should match the bottle body of the first oil bottle 110, and the size of the partition plate 132 is consistent with the inner diameter of the first oil bottle 110. The partition plate 132 is partially rotatably connected to the inner wall of the first oil bottle 110, so that when the partition plate 132 is rotated to be perpendicular to the inner wall of the first oil bottle 110, the partition plate 132 completely separates the oil collecting chamber 111 from the oil guiding chamber 112. When the partition plate 132 is rotated to be parallel to the inner wall of the first oil bottle 110, the oil guiding chamber 112 and the oil collecting chamber 111 are completely separated. 11 is connected; in addition, the number of driving members 131 and partition plates 132 can also be multiple, and multiple partition plates 132 are arranged in a circle along the inner wall of the first oil bottle 110. When the oil collecting chamber 111 is separated from the oil guiding chamber 112, the cavity of the oil collecting chamber 111 is conical. After the driving member 131 controls each partition plate 132 to rotate, the cone tip opens, so that the waste oil flows from the cone tip into the oil guiding chamber 112. The specific number of driving members 131 and partition plates 132 is not limited in the embodiment of the present application as long as the oil collecting chamber 111 and the oil guiding chamber 112 can be completely separated.

[0066] In some possible implementations, see Figure 1 As shown, the driving member 131 of the embodiment of the present application is a telescopic rod; one end of the telescopic rod is hinged to the partition plate 132, and the other end of the telescopic rod is hinged to the inner wall of the first oil bottle 110. The controller controls the extension or contraction of the telescopic rod to rotate the partition plate 132 relative to the first oil bottle 110.

[0067] In some embodiments, the driving member 131 is configured as a telescopic rod, and the two ends of the telescopic rod are respectively hinged to the partition plate 132 and the inner wall of the first oil bottle 110, so that the controller can rotate the partition plate 132 relative to the first oil bottle 110 by controlling the extension or contraction of the telescopic rod. The telescopic rod can be arranged in the oil collecting chamber 111 or in the oil guiding chamber 112, and the specific position of the telescopic rod is not limited in the embodiment of the present application, as long as it can drive the partition plate 132 to rotate.

[0068] At the same time, the telescopic rod can also play a certain supporting role. When the partition assembly 130 is closed, the telescopic rod can support the partition plate 132 to prevent the partition plate 132 from rotating due to the pressure of the waste oil, thereby enhancing the bearing capacity of the partition plate 132.

[0069] In some possible implementations, see Figure 1 As shown, the embodiment of the present application also includes a connector 140, the first oil bottle 110 includes a first bottle body 113 and a bottleneck 114 connected to the first bottle body 113; the connector 140 is arranged on the bottleneck 114, and the connector 140 is used to connect with the oil drain port so that the oil collecting chamber 111 is connected to the oil drain port; the partition assembly 130 is arranged in the first bottle body 113.

[0070] It should be noted that, since the shapes and sizes of the oil drain ports of different components are different, a connector 140 matching the shape of the corresponding oil drain port is provided on the bottleneck 114 of the first oil bottle 110 so that the oil collecting device 100 can be installed on the oil drain port. In this way, for different oil drain ports, it is only necessary to replace connectors 140 of different types without replacing the entire oil collecting device 100, thereby improving the applicability of the oil collecting device 100.

[0071] In some possible implementations, see Figure 1 As shown, a first connecting portion is provided on a side of the first bottle body 113 away from the bottleneck 114 in the embodiment of the present application; the second oil bottle 120 includes a second bottle body and a second connecting portion (not shown in the figure) provided on the second bottle body, and the first connecting portion and the second connecting portion are detachably connected.

[0072] It can be understood that the first connection part is provided at the bottom of the first bottle body 113, and the second connection part is provided at the top of the second oil bottle 120, and the first connection part is detachably connected to the second connection part, so as to realize the detachable connection between the second oil bottle 120 and the first oil bottle 110. The first connection part can be an external thread provided on the first bottle body 113, and the second connection part can be an internal thread provided on the second bottle body, so that the first connection part and the second connection part are spirally connected, and the second oil bottle 120 can be installed or removed by twisting it, which is convenient to operate and is conducive to improving the cleaning efficiency of waste oil. The specific structures of the first connection part and the second connection part are not limited in the embodiment of the present application, and it is sufficient to realize detachable connection.

[0073] In some possible implementations, see Figures 1 to 4 As shown, the embodiment of the present application also includes a reinforcement component 150, which includes a first connecting member 151, a second connecting member 152 and a mounting seat 153; the mounting seat 153 is connected to the bottleneck 114; the first connecting member 151 and the second connecting member 152 are used to be wound around the component, one end of the first connecting member 151 and one end of the second connecting member 152 are respectively connected to the opposite sides of the mounting seat 153, and the other end of the first connecting member 151 is connected to the other end of the second connecting member 152.

[0074] In a specific implementation, the stability of the oil collecting device 100 fixed only by the connection between the joint 140 and the oil drain port is relatively low. When the component is a rotatable component or moves frequently, for example, the component is a bearing 10 of a wind turbine generator set, the oil collecting device 100 may fall off, thereby causing waste oil to spill. Therefore, a reinforcement component 150 needs to be provided to further enhance the stability of the connection between the oil collecting device 100 and the component.

[0075] Specifically, the component may be a bearing 10 of a wind turbine generator set, and the reinforcement assembly 150 includes a first connecting member 151, a second connecting member 152 and a mounting seat 153. The first connecting member 151 and the second connecting member 152 are both connected to the mounting seat 153 and are wound around the bearing 10. The first connecting member 151 is then connected to the second connecting member 152, thereby binding the mounting seat 153 to the bearing 10, and the mounting seat 153 is connected to the bottleneck 114, thereby playing the role of fixing the oil collection device 100.

[0076] Among them, the first connecting member 151 and the second connecting member 152 can be workpieces with good flexibility and high strength such as chains and steel wires, so that the first connecting member 151 and the second connecting member 152 can be completely fitted with the outer surface of the component, making its binding with the component more stable. The specific structure of the first connecting member 151 and the second connecting member 152 is not limited in the embodiment of this application.

[0077] In some possible implementations, see Figure 1 , Figure 2 and Figure 3 As shown, the reinforcement component 150 of the embodiment of the present application also includes two clips 154; the clip 154 ​​includes a clamping portion 1541 and a clamping portion 1542 connected to the clamping portion 1541; a mounting hole 1531 is provided on the mounting seat 153; the bottleneck 114 is connected to the joint 140 through the mounting hole 1531, and the mounting hole 1531 and the bottleneck 114 are interference fit; the two clamping portions 1541 respectively clamp the other end of the first connecting member 151 and the other end of the second connecting member 152, and the two clamping portions 1542 are clamped.

[0078] In some embodiments, the first connecting member 151 and the second connecting member 152 are connected together by a buckle 154, and the buckle 154 includes a clamping portion 1541 and a snap-on portion 1542. The buckle 154 is clamped on the first connecting member 151 or the second connecting member 152 through the clamping portion 1541, and is snap-on to another buckle 154 through the snap-on portion 1542. In this way, the clamping portion 1541 can be clamped at a position of appropriate length on the first connecting member 151 or the second connecting member 152 according to the size of the component, so as to tie the mounting base 153 tightly to the component.

[0079] Furthermore, a mounting hole 1531 is provided on the mounting seat 153, so that the mounting seat 153 can be mounted on the bottleneck 114, and the bottleneck 114 is connected to the joint 140 through the mounting hole 1531, so that the mounting hole 1531 and the bottleneck 114 have an interference fit, so as to ensure the stability of the connection between the mounting seat 153 and the bottleneck 114, and further ensure the stability of the connection between the oil collecting device 100 and the oil discharge port.

[0080] In some possible implementations, see Figure 1 As shown, the embodiment of the present application also includes a liquid level detection component 160 and an alarm module; the liquid level detection component 160 is arranged in the oil collecting chamber 111, and is used to detect the liquid level of the waste oil in the oil collecting chamber 111, and the alarm module and the liquid level detection component 160 are both electrically connected to the controller; when the liquid level is greater than or equal to the liquid level preset value and the pressure is greater than or equal to at least one of the first preset value, the controller controls the alarm module to issue an alarm prompt.

[0081] It is understandable that regular inspections by staff may result in problems such as untimely inspections, misdetection, and missed inspections. Therefore, an alarm module and a liquid level monitoring component are provided to detect the liquid level of the waste oil in the oil collecting chamber 111 through the liquid level detection component 160. When the liquid level is greater than or equal to the preset liquid level value, it proves that the waste oil in the oil collecting chamber 111 is about to be full. The controller controls the alarm module to issue an alarm prompt to remind the staff to clean it up in time.

[0082] In order to improve the accuracy of the alarm and avoid malfunction of the liquid level detection component 160, it can be set that as long as at least one of the two conditions of the liquid level being greater than or equal to the liquid level preset value and the pressure detected by the pressure sensor being greater than or equal to the first preset value is met, the controller can control the alarm module to issue an alarm prompt.

[0083] Among them, the alarm module can be an alarm prompt that sends out a sound signal such as a buzzer, or an alarm prompt that sends out a light signal for a warning light, or a device that is connected to a communication device of a staff member or a monitoring background device, and sends an alarm message to the communication device or the monitoring background, etc. The specific structure of the alarm module is not limited in the embodiment of the present application, as long as it can remind the staff member to check in time. The liquid level detection member 160 can be a device that can detect the liquid level, such as a floating switch, and its specific structure is not limited in the embodiment of the present application.

[0084] In some possible implementations, see Figure 1 As shown, the embodiment of the present application further includes a manual switch 170; the manual switch 170 is disposed outside the first oil bottle 110, the manual switch 170 is electrically connected to the controller, and the manual switch 170 controls the partition assembly 130 to open or close through the controller.

[0085] In a specific implementation, when the waste oil in the oil collecting chamber 111 is not full, the partition assembly 130 is in a closed state. If the staff needs to clean the waste oil in advance based on maintenance and other work requirements, they can press the manual switch 170 outside the first oil bottle 110, so that the controller controls the driving member 131 to drive the partition plate 132 to rotate relative to the first oil bottle 110, thereby connecting the oil collecting chamber 111 and the oil guide chamber 112, and the waste oil flows into the second oil bottle 120. In this way, the flexibility of the oil collecting device 100 can be improved, and it is convenient to clean the waste oil in different situations.

[0086] See also Figures 1 to 4 As shown, an embodiment of the present application also provides a wind turbine generator set, including a unit body, a bearing 10 and any of the above-mentioned oil collecting devices 100; the bearing 10 is arranged on the unit body, an oil drain port is arranged on the bearing 10, and the oil collecting device 100 is connected to the oil drain port.

[0087] The structure and working principle of the oil collecting device 100 are described in detail in the above embodiments, and will not be described in detail here.

[0088] The bearing 10 of the wind turbine generator set is generally at a high height from the ground, and the operating space at the oil drain port is narrow. The oil collecting device 100 is installed on the bearing 10 of the wind turbine generator set. When the staff cleans the waste oil at high altitude, they only need to remove the second oil bottle 120 and replace it with a new second oil bottle 120. It is easy to operate, has high cleaning efficiency, and effectively prevents the waste oil from flowing out and spilling on the unit body.

[0089] In summary, the oil collecting device 100 provided in the embodiment of the present application includes a first oil bottle 110, a second oil bottle 120, a partition assembly 130, a pressure sensor and a controller, wherein the first oil bottle 110 is connected to the oil discharge port through a joint 140, and the partition assembly 130 divides the first oil bottle 110 into an oil collecting chamber 111 and an oil guiding chamber 112, and the waste oil in the oil discharge port flows into the oil collecting chamber 111 for collection. When the pressure sensor detects that the waste oil exerts a greater pressure on the partition assembly 130, it proves that the waste oil in the oil collecting chamber 111 has been fully collected, and the controller controls the partition assembly 130 to open, and the waste oil flows into the second oil bottle 120 through the oil guiding chamber 112. After the waste oil is drained, the partition assembly 130 closes the oil collecting chamber 111 to continue collecting the waste oil. In this way, when cleaning the waste oil, the staff only needs to remove the second oil bottle 120 for cleaning. During the cleaning process, the waste oil flowing out of the oil discharge port enters the oil collecting chamber 111, thereby preventing the waste oil from overflowing from the oil discharge port and spilling on the components.
