[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0038] In the above description of the present invention, it should be noted that the terms "one side" and "the other side" and the like indicate positions or locations based on the positions or locations shown in the accompanying drawings, or the positions or locations in which the product of the present invention is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0039] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0052] In this embodiment, the inclinometer assembly 2 is connected to the base 11 via a plurality of short struts;

[0053] The inclinometer assembly 2 includes an inclinometer board and three MEMS gyroscopes mounted on the inclinometer board. The function of the inclinometer assembly is to continue tracking the azimuth and attitude obtained by the north-seeking mechanism in real time after the north-seeking mechanism completes the north-seeking process, thereby maintaining the azimuth and attitude.

[0054] The inclinometer board is in electrical communication with the multi-function board.

[0055] In this embodiment, the turbine shaft includes an integrally arranged connecting disk and a shaft body; the lower end of the turbine is rollingly connected to the connecting disk via a rolling assembly, and the upper end is embedded with a rolling bearing 100 and connected to the shaft body; during implementation, the rolling bearing is fixed to the turbine shaft via a locking nut 104, and a nylon ring is provided between the locking nut and the rolling bearing;
