[0028] Figures 1-9 An embodiment of the mounting bracket for a blade rotation monitoring device of the present invention is shown, including a support frame A1, a mounting frame A2, and an adjustment mechanism A3. The mounting frame A2 is disposed at the end of the adjustment mechanism A3 and is used to mount the monitoring device. The adjustment mechanism A3 is disposed on the support frame A1 and is used to adjust the lateral position and / or longitudinal position of the mounting frame A2 so that the orientation of the mounting frame A2 is the same as the extension direction of its corresponding blade.

[0029] This invention uses a mounting bracket to place the monitoring device at the central axis of the wind turbine. The lateral and / or longitudinal position of the monitoring device on the mounting bracket A2 can be easily adjusted via the adjustment mechanism A3. This greatly improves the efficiency of installing the monitoring device and quickly aligns its orientation with the extension direction of the corresponding blade. This ensures that the monitoring range of the device accurately covers the corresponding blade position. The corresponding blade position can be the tip of the blade.

[0030] Preferred, such as Figure 2 As shown, the support frame A1 is located at the central shaft of the impeller. The support frame A1 includes a base A11, an extension seat A12, a top seat A13, and a mounting seat A14. The extension seat A12 is located between the base A11 and the top seat A13, and the mounting seat A14 is located outside the top seat A13. The base A11 is used to connect to the impeller, the extension seat A12 is used to extend the length of the support frame A1, the top seat A13 is used to connect to the mounting seat A14, and the mounting seat A14 is used to house the adjustment mechanism A3.

[0031] Preferably, the base A11 and the top seat A13 are square plate structures, and the extension seat A12 is a hollow column structure. The base A11 and the top seat A13 both extend into the extension seat A12 with protrusions that are adapted to the hollow cross section of the extension seat A12. The two ends of the extension seat A12 surround the protrusions, which facilitates the installation of the extension seat A12 and improves the stability of the mounting bracket.

[0032] Preferably, the mounting base A14 has a square plate structure and is located on the long side of the top base A13. A reinforcing rib A15 is provided between the mounting base A14 and the top base A13 to improve the firmness of the mounting base A14.

[0033] Preferred, such as Figure 3 and Figure 4As shown, the mounting bracket A2 includes a connecting plate A21 connected to the adjustment mechanism A3. The connecting plate A21 includes a connecting portion A211 connected to the adjustment mechanism 3, and an extension portion A212 extending to one side from the outer end of the connecting portion A211. The extension portion A212 is used to mount the monitoring device. The extension portion A212 increases the contact area between the mounting bracket A2 and the monitoring device, ensuring the stability of the monitoring device.

[0034] Preferably, two connecting plates A21 are symmetrically arranged, and a partition A22 is provided between the lower and upper ends of each connecting plate A21. The partition A22 can improve the connection strength between the two connecting plates A21.

[0035] Preferred, such as Figure 5 As shown, the adjustment mechanism A3 includes a first rocking component A31, which is used to adjust the lateral position of the mounting bracket A2.

[0036] Preferred, such as Figure 5 and Figure 6 As shown, the first swing assembly A31 includes a hinge A311 and an extension A312. The hinge A311 is hinged to the mounting base A14 and can swing left and right relative to the mounting base A14. The extension A312 is located in the middle of the hinge A311 and extends away from the support frame A1. There are two extensions A312, which are symmetrically arranged on the left and right sides of the mounting hole A141. The connecting part A211 of the mounting frame A2 is sandwiched between the two extensions A312.

[0037] Preferred, such as Figure 2 and Figure 6 As shown, the mounting base A14 has a mounting hole A141. First hinge plates A142 extend from the front and rear sides of the mounting base A14 away from the support frame A1. A hinge member A311 is disposed within the mounting hole A141. Both the mounting hole A141 and the hinge member A311 are square, with the width of the hinge member A311 being smaller than the width of the mounting hole A141. A second hinge plate A3111 extends from the hinge member A311 away from the support frame A1. The first hinge plate A142 and the second hinge plate A3111 are hinged together by a hinge shaft. This allows the hinge member A311 to swing left and right relative to the mounting base A14.

[0038] Furthermore, such as Figure 5 As shown, the adjustment mechanism A3 also includes a first locking component A32, which is used to lock the lateral swing position of the hinge A311.

[0039] Preferred, such as Figure 5 and Figure 8As shown, the first locking assembly A32 includes a first locking seat A321 and a second locking seat A322. The first locking seat A321 is installed on the front and rear sides of the mounting hole A141 and extends towards the support frame A1. The second locking seat A322 is installed on the front and rear ends of the hinge member A311 and extends towards the support frame A1. The first locking seat A321 and the second locking seat A322 can be fixedly connected by bolts, thereby fixing the hinge member A311 to the mounting base A14 and locking the lateral swing position of the mounting frame A2.

[0040] Preferred, such as Figure 5 and Figure 8 As shown, in one embodiment, the locking part A3212 of the first locking seat A321 and the second locking seat A322 are respectively provided with a plurality of evenly distributed first indexing holes A323. A locking pin is inserted into a pair of corresponding first indexing holes A323 to fix the first locking seat A321 and the second locking seat A322, thereby fixing the hinge A311 to the mounting seat A14 and locking the lateral swing position of the mounting bracket A2.

[0041] In another embodiment, such as Figure 5 and Figure 7 As shown, both the locking portion A3212 of the first locking seat A321 and the second locking seat A322 extend with meshing gear teeth A324. The meshing of the gear teeth A324 fixes the first locking seat A321 and the second locking seat A322, thus fixing the hinge A311 to the mounting base A14 and locking the lateral swing position of the mounting bracket A2. At this time, the first locking seat A321 can move relative to the mounting base A14, moving closer to or further away from the second locking seat A322. A slotted hole A3241 can be provided on the fixing portion A3211 of the first locking seat A321, and a bolt is installed at the slotted hole A3241. The diameter of the bolt is smaller than the diameter of the slotted hole A3241. When the bolt is loosened, the first locking seat A321 can move relative to the mounting base A14. When the first locking seat A321 approaches the second locking seat A322, it meshes with the second locking seat A322, and tightening the bolt locks the swing position of the hinge A311. When the first locking seat A321 moves away from the second locking seat A322, it separates from the second locking seat A322, allowing the first locking seat A321 to swing and adjust the swing position of the hinge A311.

[0042] Preferred, such as Figure 5 and Figure 8As shown, the first locking seat A321 includes a fixing part A3211 horizontally disposed on the mounting seat A14, and a locking part A3212 extending upward from the fixing part A3211. The locking part A3212 is provided with a first limiting hole A3213, and a first limiting bolt A3221 is provided at the first limiting hole A3213. One end of the first limiting bolt A3221 is fixed to the second locking seat A322. The width of the first limiting hole A3213 is greater than the diameter of the first limiting bolt A3221, thereby allowing the first limiting bolt A3221 to slide within the first limiting hole A3213. The first limiting bolt A3221 limits the swing path and range of the hinge member A311 relative to the mounting seat A14, ensuring the stability of the lateral swing of the hinge member A311.

[0043] Furthermore, such as Figure 5 and Figure 9 As shown, the adjustment mechanism A3 also includes a second swing assembly A33, which is used to adjust the longitudinal position of the mounting bracket A2.

[0044] Preferred, such as Figure 9 As shown, the second rocking assembly A33 includes a rocking seat A331. A rocking hole A3311 is provided in the middle of the hinge A311. The rocking seat A331 is located on the left and right sides of the rocking hole A3311, extending towards the support frame A1. The connecting plate A21 extends through the rocking hole A3311 to the upper outer side of the rocking seat A331. A second limiting hole A3312 is provided on the rocking seat A331, and a second limiting bolt A3313 corresponding to the second limiting hole A3312 is provided on the connecting plate A21. The second limiting bolt A3313 can slide within the second limiting hole A3312. The second limiting bolt A3313 limits the swing path and range of the connecting plate A21, ensuring the stability of the connecting plate A21's back-and-forth swing.

[0045] Furthermore, such as Figure 9 As shown, the rocker seat A331 is also provided with a plurality of evenly distributed second indexing holes A3314. The connecting plate A21 at the corresponding position of the second indexing hole A3314 is provided with a locking hole A213. Locking pins can be inserted into the corresponding second indexing hole A3314 and locking hole A213 to lock the connecting plate A21 and the rocker seat A331, thereby locking the longitudinal swing position of the mounting bracket A2.

[0046] Preferably, two rocker seats A331 are provided, one on the upper side and one on the lower side of the connecting plate A21. The two rocker seats A331 can further limit the swing of the connecting plate A21 and prevent the lower end of the connecting plate A21 from shaking.

[0047] Therefore, this invention discloses a mounting bracket for a blade rotation monitoring device. This invention uses the mounting bracket to precisely position the monitoring device at the optimal detection orientation of the wind turbine blades. The lateral and / or longitudinal positions of the monitoring device on the mounting bracket can be easily adjusted via an adjustment mechanism.
