[0021] The present invention will now be described in further detail with reference to the accompanying drawings.
[0022] In practice:
[0023] See the example. Figures 1-3 To address the problems existing in the prior art, this utility model proposes a manual adjustment device for north-finding angle measurement, comprising a horizontally positioned azimuth base 1 and a housing rotatably mounted on the azimuth base 1, with a mounting base 27 for mounting an optical sight instrument above the housing. The housing houses an azimuth rotation mechanism, a pitch rotation mechanism, a two-axis gyroscope 24, and a quartz flexural accelerometer 15. The azimuth rotation mechanism drives the housing to rotate horizontally on the azimuth base 1. The pitch rotation mechanism is connected to the mounting base 27 and drives the mounting base 27 to pitch in a vertical plane. The two rotation axes of the two-axis gyroscope 24 are parallel to the horizontal plane and perpendicular to each other.
[0024] This invention can find north in a stationary state using a two-axis gyroscope and a quartz flexural accelerometer. By rotating the base, it drives the optical aiming instrument mounted on the top mounting to rotate, thus achieving target orientation tracking. Furthermore, by adjusting the orientation rotation mechanism and the pitch rotation mechanism separately or simultaneously, it drives the optical aiming instrument mounted on the mounting to rotate, thereby achieving target orientation measurement and target tracking angle measurement. It has a simple structure, small size, is easy to carry, has strong sealing and anti-interference capabilities, can perform target tracking angle measurement very well, and is easy to use.
[0025] Specifically, the housing includes a base 2 and a top cover 26 that are fastened together. The base 2 is rotatably connected to the azimuth base 1. The top cover 26 has a rotating groove at its upper end. The mounting base 27 is connected to the pitch rotation mechanism through the rotating groove, and the mounting base 27 can pitch and rotate in a vertical plane along the rotating groove. The two-axis gyroscope 24 is a fiber optic gyroscope.
[0026] More specifically, the azimuth rotation mechanism includes a load bearing 3 installed in the base 2, the inner ring of which is fixedly connected to the azimuth base 1, and the outer ring of which is fixedly connected to the base 2; it also includes an azimuth turbine 4 and an azimuth worm 16, the outer teeth of which mesh with the azimuth worm 16, the azimuth turbine 4 being fixedly connected to a turbine washer 5, and the turbine washer 5 being fixedly connected to the azimuth base 1; one end of the azimuth worm 16 is provided with an azimuth gear 7, and an azimuth gear shaft 8 meshing with the azimuth gear 7 is rotatably mounted on the base 2, the azimuth gear shaft 8 extending out of the base 2 and connected to a first handwheel 9 on the outer side of the base 2. Rotating the first handwheel 9 drives the azimuth gear shaft 8 to rotate, the azimuth gear shaft 8 drives the azimuth gear 7 to rotate, and the azimuth worm 16 rotates and rotates around the azimuth turbine 4 under the meshing action, thereby driving the entire base 2 to rotate horizontally.
[0027] It also includes an orientation encoder 6, the stator end of which is fixed on the turbine washer 5, and the rotor end is fixed to the base 2. In this way, the orientation encoder 6 can effectively obtain the horizontal rotation angle of the housing.

[0029] The pitch rotation mechanism includes a pitch drive shaft 20 and a pitch sub-shaft 12 rotatably mounted inside the top cover 26 and coaxially arranged. The pitch drive shaft 20 and the pitch sub-shaft 12 are rotatably mounted inside a pitch sleeve 13. The pitch sleeve 13 is fixedly mounted on the top cover 26, and sealing rings are filled between the pitch sleeve 13 and the pitch drive shaft 20 and the pitch sub-shaft 12, as well as between the pitch sleeve 13 and the top cover 26. Specifically, the pitch sleeve 13 is mounted on a pitch bearing 10, and the pitch bearing 10 is sealed to the top cover 26 by the sealing rings.

A bevel gear 22 is provided at one end of the pitch worm gear 21, and a bevel gear shaft 19 that meshes with the bevel gear 22 is rotatably mounted on the base 2. The bevel gear shaft 19 extends out of the base 2 and is connected to a second handwheel on the outside of the base 2. Specifically, the bevel gear shaft 19 is connected to the base 2 via a bevel gear shaft seat 18, and a sealing ring is provided between the bevel gear shaft seat 18 and the base 2. Turning the second handwheel causes the bevel gear shaft 19 to rotate, which in turn drives the pitch worm gear 21 to rotate. The pitch worm gear 21 drives the pitch transmission shaft 20 to rotate through the pitch turbine 23, which in turn drives the mounting base 27 to pitch and rotate in the vertical plane.
[0031] It also includes a pitch encoder 14, the rotor end of which is connected to the pitch subshaft 12, and the stator end is fixed on an encoder base 11, which is fixed on the top cover 26.
