Description

Technical Field

[0001] This utility model relates to the field of astronomical observation equipment technology, and in particular to a two-dimensional turntable for suspending multiple astronomical telescopes. Background Technology

[0002] A two-dimensional turntable for astronomical observation is a precision device capable of rotating within two mutually perpendicular planes. It is primarily used to adjust the angles of observation instruments to achieve precise positioning and tracking of celestial bodies. For example, Chinese patent CN201921914877.6 discloses a radiometric correction device for remote sensing data, which includes a support base, a support column, a detection head, and an internal focusing telescope. The support column is perpendicularly connected to the upper surface of the support base, and the upper surface of the support column is connected to the detection head. The internal focusing telescope is embedded within the detection head, and the detection head and support column are hinged via a two-dimensional turntable. This device can only accommodate one telescope in the detection head. When observing celestial bodies at different distances, the focal length of the telescope needs to be adjusted separately, which is time-consuming and labor-intensive. Utility Model Content

[0018] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0019] like Figure 1 The diagram shows a schematic representation of the structure of a two-dimensional turntable for suspending multiple astronomical telescopes provided by this invention. The two-dimensional turntable includes a base 10, a horizontal rotation component 20 disposed on the base 10, a limiting component 30 disposed within the horizontal rotation component 20, a pitch rotation component 40 disposed on the horizontal rotation component 20, and a mounting component 50 disposed on the pitch rotation component 40. It is conceivable that the two-dimensional turntable for suspending multiple astronomical telescopes also includes other functional modules, such as a power supply module, a screw module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0020] The base 10 serves as a support platform to support the horizontal rotation component 20 and the pitch rotation component 30, and the interior of the base 10 can be used for cable arrangement.

[0021] Please refer to the following: Figures 2 to 4 The horizontal rotation assembly 20 includes a chassis 21, a first rotating shaft 22 fixedly mounted on the chassis 21, a fixed plate 23 mounted on the side of the chassis 21 away from the base 10, a horizontal axis motor 24 fixedly mounted on the fixed plate 23, a connecting ring 25 mounted on the output end of the horizontal axis motor 24, and a moving plate 26 fixedly connected to the connecting ring 25.

[0022] The chassis 21 is fixedly mounted on the base 10, and its surface has a through hole for passing cables through, so that the horizontal axis motor 24 and the power module can be electrically connected.

[0023] The first rotating shaft 22 is located at the center of the chassis 21 and is hollow inside, so that the cable in the base 10 can be passed through the vertical shaft 21 and reach the pitch rotation component 40, so that the pitch rotation component 40 can be electrically connected to the power module.

[0024] The fixed plate 23 and the chassis 21 are fixedly connected by an annular sleeve 27. The sleeve 27 can protect the internal components and prevent dust and corrosion. The space inside the sleeve 27 can also be used for cable arrangement.

[0025] The horizontal axis motor 24 is a frameless torque motor, a high-performance special motor that uses rotor and stator core components and omits the traditional outer casing structure, allowing electromagnetic components to be embedded inside the equipment. The motor works by generating torque through the interaction of the magnetic field between permanent magnets and electromagnetic windings, thus converting electrical energy into mechanical energy. The working principle of the horizontal axis motor 24 is existing technology and will not be elaborated further here. The horizontal axis motor 24 can drive the connecting ring 25 to rotate, thereby causing the moving disk 26 to rotate around its center, achieving horizontal rotation.

[0026] The limiting component 30 includes a limiting rod 31, a limiting seat 32 disposed on one side of the limiting rod 31, and a swing block 33 rotatably disposed on the limiting seat 32.

[0027] The limiting rod 31 is fixedly mounted on the moving plate 26, and its length direction is towards the fixed plate 23.

[0028] The limiting seat 32 is fixedly mounted on the fixed plate 23 and corresponds to the limiting rod 31.

[0029] The swing block 33 is crescent-shaped, with its concave surface facing the fixed plate 23. Two circular grooves 34 are spaced apart in the middle section of the convex surface of the swing block 33. A ball plunger 35 is provided in the middle section of the limiting seat 32. The two circular grooves 34 can be respectively locked in the ball plunger 35, thereby fixing the rotation state of the swing block 33.

[0030] When the limiting rod 31 rotates with the moving disk 26, it deflects the swing block 33, causing it to tilt to one side. After rotating 360° around the center of the moving disk 26, the limiting rod 31 reaches the other side of the swing block 33. At this point, the side of the swing block 33 away from the limiting rod 31 abuts against the limiting seat 32, and the limiting rod 31 abuts against the other side of the swing block 33, thus restricting its further movement and achieving the purpose of limiting the rotation of the moving disk 26.

[0031] The pitch rotation assembly 40 includes a housing 41, a pitch axis motor 42 fixedly mounted on the inner wall of the housing 41, and a second rotating shaft 43 mounted on the output end of the pitch axis motor 42.

[0032] The cover 41 is fixedly mounted on the moving plate 26 by screws, so that the pitch rotation assembly 40 can rotate with the moving plate 26.

[0033] The structure of the pitch axis motor 42 is the same as that of the horizontal axis motor 24. Both are frameless torque motors that can drive the second rotating shaft 43 to rotate around the axis of the second rotating shaft 43 to achieve rotation in the pitch direction.

[0034] One end of the second rotating shaft 43 is fixedly mounted on the output end of the pitch axis motor 43, and the other end is fixedly mounted on a bearing 45. The outer circumferential wall of the bearing 45 is fixedly mounted on the cover 41. In this way, the second rotating shaft 43 can rotate under the drive of the pitch axis motor 42 while ensuring the stability of both ends.

[0035] The mounting assembly 50 includes a connecting rod 51 passing through the second rotating shaft 33, at least two support blocks 52 respectively disposed at both ends of the connecting rod 51, and a plurality of sliders 53 respectively disposed on the two support blocks 52.

[0036] It should be noted that the two-dimensional turntable for suspending multiple astronomical telescopes is used to suspend multiple astronomical telescopes 60 on the mounting component 50. The multiple astronomical telescopes 60 can be set with different focal lengths, so that stars at different distances can be observed simultaneously without adjusting the focal length of the astronomical telescopes, thus saving debugging operations and debugging time.

[0037] The slider 53 is fixedly mounted on the astronomical telescope 60 so that the astronomical telescope 60 is fixedly mounted on the hanging assembly 50 by the locking structure between the slider 53 and the support block 52. The specific locking structure will be described below.

[0038] The connecting rod 51 is fixedly inserted into the second rotating shaft 33 via a flange. The exposed portion of the connecting rod 51 can be balanced by inserting counterweights to maintain the weight distribution at both ends, thus ensuring the two-dimensional turntable remains stress-balanced and preventing tilting when different numbers of astronomical telescopes 60 are hung at both ends of the mounting assembly 50. Within the load-bearing capacity of the connecting rod 51, multiple support blocks 52 can be hung at both ends. Each support block 52 can have a slider 53 connected to both sides, allowing multiple astronomical telescopes 60 to be hung on the mounting assembly 50.

[0039] The support block 52 and the slider 53 are connected by a dovetail structure, and the slider 53 is limited in two directions, so that the slider 53 can only slide in the support block 52 to adjust the placement of the astronomical telescope 60.

[0040] At least two locking blocks 54 are provided on one side of the support block 52, which can lock the slider 53 by turning the locking screw, thereby fixing the slider 53.

[0041] Compared with the prior art, the two-dimensional turntable for suspending multiple astronomical telescopes provided by this utility model realizes the full-circle rotation of the mounting component 50 through the horizontal rotation component 20 and the pitch rotation component 40. The mounting component 50 can hang multiple astronomical telescopes 60 with different focal lengths, so that stars at different distances can be observed at the same time, eliminating the need for adjustment of the astronomical telescopes 60 and saving debugging time.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
