Description

Technical Field

[0001] This application relates to the field of auxiliary tool technology, and in particular to an installation structure and a wind turbine hub assembly. Background Technology

[0002] To detect the rotational speed of a wind turbine, sensors are typically installed on the turbine hub. Currently, sensors are generally installed by creating a hole at the mounting location on the turbine hub. However, after prolonged use, the sensors are prone to loosening and interference with other components, leading to sensor damage. Utility Model Content

[0003] This application addresses the problem that existing sensors are prone to loosening and damage during installation, and proposes an installation structure and a wind turbine hub assembly. This installation structure improves the installation stability of the sensor and protects the sensor at the same time.

[0004] In a first aspect, this application provides an installation structure for mounting a sensor on a wind turbine hub, comprising:

[0005] The clamping section has a first through hole extending in a first direction inside, and the outer wall of the clamping section is used to connect with the wind turbine hub.

[0006] The mounting section is connected to the clamping section. The interior of the mounting section is provided with a second through hole extending along the first direction. The second through hole communicates with the first through hole. The diameter of the second through hole is smaller than the diameter of the first through hole and is used to install a sensor. The outer wall of the mounting section is used to connect with the wind turbine hub.

[0007] In one embodiment, the mounting structure further includes a transition section, one end of which is connected to the clamping section and the other end of which is connected to the mounting section. The transition section has a third through hole, which is connected to the first through hole and the second through hole. The diameter of the third through hole is larger than that of the second through hole.

[0008] In one embodiment, along the first direction, the length of the transition segment is greater than or equal to the length of the clamping segment.

[0009] In one embodiment, along the first direction, the outer walls of the clamping section, the mounting section, and the transition section are all provided with first threads that are connected in sequence, and the mounting structure is connected to the wind turbine hub through the first threads.

[0010] In one embodiment, the clamping section further includes an abutment portion, which is circumferentially spaced on the outer wall of the clamping section along the first through hole and is used to be clamped by an external clamping member, wherein the abutment portion extends along the first direction and avoids the first thread.

[0011] In one embodiment, the clamping section, the mounting section, and the transition section are manufactured using an integral molding process.

[0012] In one embodiment, the wall of the second through hole is provided with a second thread extending along the first direction, and the mounting structure further includes a connector, in which the sensor is installed, the connector being located within the second through hole and connected to the second thread.

[0013] In one embodiment, along the first direction, the length of the mounting segment is greater than the length of the clamping segment.

[0014] In one embodiment, the mounting structure further includes a locking member, the clamping section having a first mounting hole extending radially along the first through hole, the locking member passing through the fan hub into the first mounting hole, and the mounting section having a second mounting hole extending radially along the second through hole, the locking member passing through the fan hub into the second mounting hole.

[0015] Secondly, this application provides a wind turbine hub assembly, including the mounting structure in the above embodiments.

[0016] The aforementioned mounting structure allows the sensor to be installed internally, protecting it as much as possible without affecting its performance and improving installation stability. Secondly, because both the clamping section and the outer wall of the mounting section are connected to the wind turbine hub, the contact area between the mounting structure and the hub is increased, thereby improving the installation stability of the structure and, consequently, the sensor.

[0027] Please see Figure 1 and Figure 2 This application provides an installation structure 100 for mounting a sensor on a wind turbine hub. The installation structure 100 includes a clamping section 10 and an installation section 20. The clamping section 10 has a first through hole 11 extending along a first direction X inside, and the outer wall of the clamping section 10 is used to connect with the wind turbine hub. The installation section 20 is connected to the clamping section 10, and the installation section 20 has a second through hole 21 extending along the first direction X inside, which communicates with the first through hole 11. The diameter of the second through hole 21 is smaller than the diameter of the first through hole 11, and it is used to mount the sensor. The outer wall of the installation section 20 is used to connect with the wind turbine hub.

[0028] The structure of clamping section 10 is similar to that of mounting section 20; both can be constructed as cylindrical structures.

[0029] During sensor assembly, the sensor can be inserted from the side of the first through hole 11 away from the second through hole 21, and gradually pushed into the second through hole 21, where it can be fixed in place. The user can change the degree to which the sensor is exposed to the mounting structure 100 by moving the sensor within the second through hole 21.

[0030] After the sensor is assembled onto the mounting structure 100, the mounting structure 100 can be assembled. The clamping section 10 and the mounting section 20 of the mounting structure 100 are both connected to the wind turbine hub to improve the installation stability of the entire mounting structure 100.

[0031] In summary, installing the sensor inside the mounting structure 100 protects the sensor as much as possible without affecting its performance and improves its installation stability. Secondly, because the outer walls of both the clamping section 10 and the mounting section 20 of the mounting structure 100 are connected to the wind turbine hub, the contact area between the mounting structure 100 and the wind turbine hub is increased, thereby improving the installation stability of the mounting structure 100 and, consequently, the installation stability of the sensor.

[0032] like Figure 2 As shown, in some embodiments, the mounting structure 100 further includes a transition section 30, one end of which is connected to the clamping section 10 and the other end is connected to the mounting section 20. The transition section 30 is provided with a third through hole 31, which is connected to the first through hole 11 and the second through hole 21. Moreover, the diameter of the third through hole 31 is larger than that of the second through hole 21.

[0033] The transition section 30 can also be constructed as a cylindrical structure. The diameter of the third through hole 31 within the transition section 30 can be equal to that of the first through hole 11, or the diameter of the third through hole 31 can be smaller than that of the first through hole 11. It is only necessary to ensure that the diameter of the third through hole 31 is larger than that of the second through hole 21. This facilitates the smooth passage of the sensor through the third through hole 31.

[0034] The transition section 30 is provided between the clamping section 10 and the mounting section 20 to increase the length of the clamping section 10 in the first direction X, so that the clamping section 10 can be clamped by different types of clamping members, thus expanding the application range of the mounting structure 100.

[0035] Furthermore, in some embodiments, along the first direction X, the length of the transition segment 30 is less than or equal to the length of the clamping segment 10.

[0036] For example, in some examples, the length of the transition section 30 and the length of the clamping section 10 are equal, both being 15 mm. In other examples, the length of the transition section 30 is 15 mm, and the length of the clamping section 10 is 14 mm.

[0037] This design can mitigate the waste of materials caused by an excessively long transition section 30, thus saving materials as much as possible.

[0038] Please see Figure 1 and Figure 2 In some embodiments, along the first direction X, the outer walls of the clamping section 10, the mounting section 20 and the transition section 30 are all provided with first threads 40 connected in sequence, and the mounting structure 100 is connected to the wind turbine hub through the first threads 40.

[0039] When assembling the mounting structure 100, the entire mounting structure 100 is installed in the wind turbine hub, and the mounting structure 100 is connected to the wind turbine hub by the first thread 40. Because the outer walls of the clamping section 10, the mounting section 20 and the transition section 30 are all provided with the first thread 40, the contact area between the entire mounting structure 100 and the wind turbine hub can be increased, thereby improving the adjustment accuracy between the sensor and the slip ring measuring plate of the wind turbine hub.

[0040] Please continue reading. Figure 1 In some embodiments, the clamping section 10 further includes an abutment portion 12, which is circumferentially spaced on the outer wall of the clamping section 10 along the first through hole 11 and is used to be clamped by an external clamping member. The abutment portion 12 extends along the first direction X and avoids the first thread 40.

[0041] For example, a portion of the outer wall of the clamping section 10 is not provided with the first thread 40, these portions extend along the first direction X, and the first through holes 11 are circumferentially spaced, thereby being configured as the abutment portion 12.

[0042] In actual use, the clamping arm of the clamping member can contact the abutment part 12, which is equivalent to setting the first thread 40 on the entire outer wall of the clamping section 10, so that the clamping arm of the clamping member is clamped on the first thread 40 and the clamping arm is clamped on the abutment part 12. This increases the contact area between the clamping arm and the clamping section 10, thereby increasing the friction between the two and improving the stability during the clamping process.

[0043] In some embodiments, the clamping section 10, the mounting section 20, and the transition section 30 are manufactured using an integral molding process.

[0044] This configuration not only improves the connection strength between adjacent sections of clamping section 10, mounting section 20, and transition section 30, but also simplifies the manufacturing process.

[0045] like Figure 2 As shown, in some embodiments, the wall of the second through hole 21 is provided with a second thread 211 extending along the first direction X. The mounting structure 100 also includes a connector (not shown in the figure), in which a sensor is installed. The connector is located in the second through hole 21 and is connected to the second thread 211.

[0046] The connector has an internal slot extending along the first direction X to hold and protect the sensor. The outer wall of the connector has a third thread that mates with the second thread 211 to connect the connector to the mounting structure 100. Because the sensor and mounting structure 100 are connected via the connector, and both the connection between the mounting structure 100 and the connector, and between the connector and the sensor, are detachable, the installation of these components is convenient. Furthermore, if at least one of the mounting structure 100, the connector, or the sensor is damaged, the damaged component can be replaced, reducing maintenance costs.

[0047] Specifically, in some embodiments, the length of the mounting segment 20 is greater than the length of the clamping segment 10 along the first direction X.

[0048] For example, the length of the mounting section 20 is 30mm, and the length of the clamping section 10 is 15mm. This arrangement allows for the miniaturization of the mounting structure 100 while maximizing the proportion occupied by the mounting section 20, thereby improving the connection stability between the connector and the mounting section 20.

[0049] In some embodiments, the mounting structure 100 further includes a locking member (not shown in the figure), the clamping section 10 is provided with a first mounting hole extending radially along the first through hole 11, the locking member passes through the fan hub and enters the first mounting hole, and the mounting section 20 is provided with a second mounting hole extending radially along the second through hole 21, the locking member passes through the fan hub and enters the second mounting hole.

[0050] For example, bolts can be used as locking elements. The mounting structure 100 is equipped with two locking elements, one of which passes through the fan hub into the first mounting hole of the clamping section 10, and the other passes through the fan hub into the second mounting hole of the mounting section 20.

[0051] In this way, the two ends of the mounting structure 100 can be connected to the wind turbine hub in the first direction X, which improves the installation stability of the mounting structure 100.

[0052] In some embodiments, the mounting structure 100 is constructed as a metal component.

[0053] Because the wind turbine hub is also made of metal, it can leak the induced current generated by the sensor housing during operation, reducing the probability of safety chain failure.

[0054] Furthermore, this application also provides a wind turbine hub assembly, which includes the mounting structure 100 in the above embodiments. Since the wind turbine hub assembly includes the mounting structure 100, it possesses all the beneficial effects of the mounting structure 100, which will not be elaborated further here.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
