Description

Technical Field

[0001] The utility model relates to the technical field of equatorial mounts, and in particular to a polar axis calibration mechanism for an equatorial mount. Background Art

[0002] The equatorial mount is an important component used to overcome the influence of the earth's rotation on stargazing. Due to the rotation of the earth, the stars seen by observers on the ground move along an arc from east to west. The trajectory is a concentric circle with the center of the circle being the North celestial pole (relative to the northern hemisphere). The function of the equatorial mount is to allow the telescope to move along this arc so that the target always remains in the field of view. In astronomical coordinates, the direction of this arc motion is the right ascension direction. There are three axes on the equatorial mount: the horizontal axis, the declination axis and the polar axis. The axis of the polar axis is used to point to the stars when observing the stars. In other words, the axis of the polar axis is perpendicular to the right ascension direction when observing the stars.

[0003] However, in the prior art, after the equatorial mount is adjusted to the level, if the traditional equipment is accidentally hit and the equatorial mount is tilted, the equatorial mount can only be adjusted to the level again, which affects the operation of the equatorial mount. In addition, after the equatorial mount loses a star, because the traditional equipment cannot quickly rotate the equatorial mount, the traditional equipment can only move and rotate the equatorial mount, calibrate the equatorial mount, and then align it with the star, thereby increasing the working time of the staff.

The outer wall of the soft sleeve 46 contacts the outer wall of the gear 42, and the outer wall of the gear 42 contacts the outer wall of the support rib 47.

[0036] Working principle:

[0037] When in use, first place the base plate 1 on the ground, and then place the equatorial mount in the rotating mechanism 4 in the top plate 7, and the supporting mechanism 3 at the bottom of the rotating mechanism 4 is used to support the level of the rotating mechanism 4. During use, the staff accidentally hits the top plate 7, causing the level of the equatorial mount to change. A supporting mechanism 3 is provided at the bottom of the top plate 7, and the supporting mechanism 3 is fixed to the base plate 1 through a frame 2. With the fixation of the frame 2, the position of the supporting mechanism 3 is fixed. After the position of the top plate 7 changes, because the top plate 7 is connected to the base plate 1 through the wrapping ring 5 and the supporting column 6, the top plate 7 is tilted and pressed onto the supporting mechanism 3, and then the level of the equatorial mount is adjusted by the supporting mechanism 3. The rotating mechanism 4 can quickly rotate the angle of the equatorial mount, so that the staff can quickly align the equatorial mount with the celestial body.

[0038] When the top plate 7 is pressed by the outside world and causes the top plate 7 to tilt, the support mechanism 3 at the pressed position will lift up the top plate 7 at the tilted position, so as to keep the equatorial mount level. After the top plate 7 tilts downward, the fixed cylinder 35 below the top plate 7 moves downward synchronously. A pressure column 34 is provided below the fixed cylinder 35. Therefore, when the fixed cylinder 35 moves downward and contacts the pressure column 34, the pressure column 34 presses downward to the air bag 32 in the fixed shell 31. The air bag 32 is connected to the cavity in the fixed cylinder 35 through the air pipe 33. After the air bag 32 is pressed by the pressure column 34, The air in the airbag 32 moves to the fixed cylinder 35 through the air pipe 33. After the air enters the fixed cylinder 35, the air pressure in the fixed cylinder 35 increases, forcing the piston 36 to move upward, thereby driving the connecting column 37 on the piston 36 to move upward. The connecting column 37 is connected to the rotating plate 45 through the sliding ball 38 and the fixed sleeve 44, so that the rotating plate 45 moves upward, thereby lifting the inclined rotating plate 45, and then keeping the rotating plate 45 level. Because the sliding ball 38 slides in the fixed sleeve 44, it will not affect the movement of the connecting column 37.

[0039] When the force pressing the top plate 7 disappears, under the action of the top spring 39, the top spring 39 pushes the piston 36 to move downward, thereby driving the rotating plate 45 to return to its original position. During the downward movement of the piston 36, the air below the piston 36 returns to the airbag 32 through the air pipe 33, and the cavity in the airbag 32 is replenished, thereby causing the airbag 32 to expand, lifting the pressure column 34 so that the fixed cylinder 35 drives the top plate 7 to return to its original position. After the top plate 7 is returned to its original position, it can play a supporting role again to cope with the external pressure force.

[0040] When it is necessary to adjust the equatorial mount to align with the celestial body, it is only necessary to pull out the limit handle 43, and then rotate the working plate 41 so that the working plate 41 drives the equatorial mount to rotate. In the process of rotating the working plate 41, because the working plate 41 is fixed with a gear 42, and the top plate 7 is fixed with a soft sleeve 46, during the rotation of the working plate 41, the gear 42 contacts the soft sleeve 46, and a supporting rib 47 is fixed on the soft sleeve 46. Under the support of the supporting rib 47, after the soft sleeve 46 contacts the gear 42, the rotation speed of the working plate 41 is slowed down, so that the rotation speed of the working plate 41 can be controlled. In the rotation process, the cooperation between the gear 42 and the soft sleeve 46 can be used to fine-tune the angle of the working plate 41. After the adjustment work of the equatorial mount is completed, the limit handle 43 is reinserted into the soft sleeve 46 so that the soft sleeve 46 has a supporting force, thereby blocking the rotation of the gear 42, and then fixing the working plate 41, so that the position of the equatorial mount remains fixed.
