[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an ultrasonic wind measuring device. (Refer to...) Figure 1 An ultrasonic anemometer includes a base 1, a horizontal moving assembly 2, a connecting shaft 3, an ultrasonic anemometer 4, and a mounting base 5. The base 1 is fixed to the top of the generator nacelle. The horizontal moving assembly 2 is mounted on the base 1. The connecting shaft 3 is mounted on the moving end of the horizontal moving assembly 2. The ultrasonic anemometer 4 is mounted on the connecting shaft 3 via the mounting base 5.

[0032] Reference Figure 1 and Figure 2 The base 1 includes a mounting box 11, a mounting plate 12, and a second drive motor 13. A circular 542-shaped protruding plate 111 is fixed to the bottom of the outer side of the mounting box 11. Four threaded rods 112 are evenly distributed circumferentially on the upper surface of the protruding plate 111. The threaded rods 112 are threaded onto the protruding plate 111, facilitating the fixing of the mounting box 11 to the top of the generator set nacelle. The mounting plate 12 is horizontally positioned and rotatably connected to the top of the mounting box 11. A horizontal moving assembly 2 is mounted on the upper surface of the mounting plate 12. The second drive motor 13 is fixed inside the mounting box 11, and its output end is fixedly connected to the mounting plate 12. Start the second drive motor 13, which can drive the mounting plate 12 to rotate, thereby causing the horizontal moving component 2 mounted on the mounting plate 12 to rotate, which in turn causes the connecting shaft 3 and the ultrasonic anemometer 4 to rotate, thereby changing the installation position of the ultrasonic anemometer 4. This eliminates the need to remove the ultrasonic anemometer 4 if it is not installed accurately, making it easier to install the ultrasonic anemometer 4.

[0033] Reference Figure 1 and Figure 2The horizontal moving assembly 2 includes a fixed plate 21, a screw 22, a first drive motor 23, a guide rod 24, and a slider 25. Two fixed plates 21 are symmetrically fixed on both sides of the upper surface of the mounting plate 12. The screw 22 is rotatably connected between the two fixed plates 21. The first drive motor 23 is fixedly connected to the outer side of one of the fixed plates 21, and its output end is fixedly connected to the screw 22. The guide rod 24 is fixedly connected between the two fixed plates 21. One side of the slider 25 is threaded to the screw 22, and the other side is slidably connected to the guide rod 24. A connecting shaft 3 is mounted on the upper surface of the slider 25. Start the first drive motor 23, which can drive the screw 22 to rotate. The rotation of the screw 22 can drive the slider 25 to move on the screw 22, so that the connecting shaft 3 and the ultrasonic anemometer 4 can move, thereby changing the installation position of the ultrasonic anemometer 4. This eliminates the need to remove the ultrasonic anemometer 4 if it is not installed accurately, making it easier to install the ultrasonic anemometer.

[0034] Reference Figure 1 and Figure 2 The movement trajectory of the connecting shaft 3 can pass through the rotation center of the mounting plate 12, maximizing the movement range of the connecting shaft 3 and making the installation range of the ultrasonic anemometer 4 wider. The connecting shaft 3 includes an outer cylinder 31, an inner rod 32, and a limiting bolt 33. The outer cylinder 31 is fixedly connected to the upper surface of the slider 25. The inner rod 32 is connected to the ultrasonic anemometer 4 and is slidably connected inside the outer cylinder 31. Multiple evenly distributed first limiting grooves are formed on the outer side of the inner rod 32 along the axial direction. The limiting bolt 33 is threaded onto the outer cylinder 31 and passes through the outer cylinder 31 and is inserted into the first limiting groove of the inner rod 32. By moving the inner rod 32, the length of the connecting shaft 3 can be changed, thereby changing the installation height of the ultrasonic anemometer 4 and thus changing the installation position of the ultrasonic anemometer 4. This allows for the installation of the ultrasonic anemometer 4 without removal if the installation is inaccurate, facilitating its installation.

[0035] Reference Figure 1 and Figure 3The mounting base 5 is fixed to the top of the inner rod 32. A mounting groove 51 is formed in the middle of the upper surface of the mounting base 5. A through hole 52 is formed in the middle of the outer side of the mounting base 5. A flared groove 53 is formed on the side wall of the through hole 52. A limiting shaft 54 ​​is inserted into the through hole 52 of the mounting base 5. A ring 542 is fixed to the outer end face of the limiting shaft 54. A boss 541 is fixed to the outer side of the limiting shaft 54, and the boss 541 is slidably connected in the flared groove 53. A spring 55 is installed in the flared groove 53 of the mounting base 5. One end of the spring 55 is fixed to the end face of the flared groove 53, and the other end is fixed to the end face of the boss 541. The ultrasonic anemometer 4 can be inserted into the mounting groove 51, and a second limiting groove for the limiting shaft 54 ​​to be inserted is formed on the outer side of the bottom of the ultrasonic anemometer 4.

[0036] Reference Figure 1 and Figure 3 During installation of the ultrasonic anemometer 4, pulling the ring 542 disengages the limiting shaft 54 ​​from the mounting groove 51, allowing the operator to insert the ultrasonic anemometer 4 into the mounting groove 51. After the ultrasonic anemometer 4 is inserted into the mounting groove 51, releasing the ring 542 causes the limiting shaft 54 ​​to insert into the second limiting groove under the action of the spring 55. This secures the ultrasonic anemometer 4, facilitating its installation. During removal of the ultrasonic anemometer 4, pulling the ring 542 disengages the limiting shaft 54 ​​from the second limiting groove, allowing the operator to remove the ultrasonic anemometer 4, facilitating its disassembly.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
