Abstract
The utility model provides an equatorial instrument which mainly comprises a supporting pedestal, a right ascension axis seat, a declination axis seat, a right ascension worm wheel, a right ascension shaft, a right ascension nut, a balance rod seat, a worm, a balance rod, and a counter weight. The right ascension axis seat is fixed on the supporting pedestal, and the pi end of the declination axis seat is clamped on the right ascension axis seat. Moreover, one end of the right ascension axis seat is changed to be circular, is fixed on the supporting pedestal, and is supported through an arc surface. The declination axis seat can rotate in 108-degree range around the right ascension axis seat. The right ascension worm wheel is fastened through the right ascension nut, is fixed on the right ascension shaft, and can be adjusted freely. The worm is fixed in a clamping groove on the right ascension axis seat. The declination axis seat, the balance rod and the right ascension axis seat form a Z-shaped structure. The balance rod seat is connected with the right ascension shaft. The counter weight is sleeved on the balance rod and can adjust the balance in a sliding manner. A swallow-tailed seat is fixed on a declination shaft, and the other end is fixed with a telescope, thereby enabling the circle center of the whole system to be above a supporting point of the supporting pedestal.
Description
Technical field:
The present invention relates to a kind of equatorial telescope, is to be used in conjunction with a kind of astronomical observation instrument with telescope, specifically right ascension axle bed, declination axle bed and base for supporting composition.Equatorial telescope is to make for flat device shortcoming with improvement, and its fundamental purpose is exactly to want to overcome earth rotation to seeing the impact of star.
Background technology:
At present, on market, a lot of equatorial telescopes, be respectively De Shi and V shape equatorial telescope, but mechanism are loaded down with trivial details, and wherein the most common moral formula equatorial telescope structure, as accompanying drawing 1, mainly comprises: base for supporting, right ascension axle bed, declination axle bed, balance stem and weight.Telescope and weight lay respectively at the two ends of declination axle bed, in T shape, right ascension axle bed is positioned on base, mutually vertical with declination axle bed, and center of gravity is positioned at base exterior, in the process of use, be unfavorable for the stable of structure, and declination axle bed and right ascension axle bed and base depart from greatlyr, structure is too disperseed, and has increased the difficulty of using.
Summary of the invention:
The technical issues that need to address of the present invention are the deficiencies that overcome background technology, and a kind of equatorial telescope solution is provided.
The technical problem to be solved in the present invention is such realization: this equatorial telescope mainly includes base for supporting, right ascension axle bed, declination axle bed, right ascension worm gear, right ascension axle, right ascension nut, balance pole socket, worm screw, balance stem, balance weight formation.Right ascension axle bed is fixed on base for supporting, declination axle bed π end is stuck on right ascension axle bed, and right ascension axle bed one end changes circle into and is fixed on and on base for supporting, utilizes cambered surface to support contact, declination axle bed can rotate within the scope of right ascension axle bed 180 degree, right ascension worm gear is locked and is fixed on right ascension axle by right ascension nut, can freely adjust, worm screw is fixed in the draw-in groove on right ascension axle bed, declination axle bed becomes zigzag with balance stem with right ascension axle bed, balance pole socket is connected with right ascension axle, balance weight is enclosed within on balance stem can slidable adjustment balance, dovetail mount is fixed on declination axle bed, the other end and telescope are fixed, thereby the center of gravity that makes whole system drops on the strong point top of base for supporting.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is described in further detail
Fig. 1 is basic structure and the force diagram of traditional moral formula equatorial telescope
The basic system of Fig. 2 equatorial telescope of the present invention and force diagram
The detail drawing of Fig. 3 embodiment of the present invention
Embodiment:
Figure 1 shows that the structure of the moral formula equatorial telescope that background money technology is mentioned, center of gravity G is positioned at base exterior and support departs from far and structure is too disperseed, and is unfavorable for Stability Analysis of Structures.
Figure 2 shows that the basic structure of equatorial telescope of the present invention, shown in Fig. 2, center of gravity G is positioned at base for supporting top, overlap with the strong point, right ascension axle bed one end changes circle into and is fixed on circular arc base, declination axle bed one end changes π shape into and is stuck on right ascension axle bed, and the other end is connected with dovetail mount, has improved the stability of whole physical construction.
Embodiments of the present invention shown in Fig. 3, right ascension axle bed 2 is fixed on base for supporting 1, and declination axle bed 3 is stuck on right ascension axle bed 2, can within the scope of right ascension axle bed 2180 degree, rotate.Right ascension worm gear 5 is fixed on right ascension axle 6, and by 7 lockings of right ascension nut, worm screw 9 is fixed in the draw-in groove on right ascension axle bed 2.Balance pole socket 8 is connected with right ascension axle 6, and balance weight 11 is enclosed within can slidable adjustment balance on balance stem 10.Dovetail mount 4 is fixed on declination axle bed 3, and the other end and telescope are fixed.Thereby the center of gravity that makes whole system drops on the strong point top of base for supporting 1.
