Description

Technical Field

[0001] The utility model relates to the field of equatorial mount controllers, in particular to an equatorial mount controller which is convenient for heat dissipation. Background Art

[0002] The equatorial mount was created to improve the shortcomings of the horizontal device. Its main purpose is to overcome the effect of the earth's rotation on stargazing. A set of standard astronomical telescopes is often composed of a telescope, an equatorial mount, a tripod and other components. When using an equatorial mount, its polar axis must first be aligned with the North Celestial Pole. (Ideally) after full alignment, the telescope does not need to be adjusted in declination for any star it is facing. It only needs to rotate the telescope at a constant speed in the right ascension (or hour angle) direction according to the speed of the star's travel, so that the star can always remain in the field of view of the telescope. The equatorial mount controller uses external electrical components to automatically align the polar axis through numerical control.

[0003] However, although the existing technology has many technical advantages, it has the disadvantage that when the traditional equatorial mount controller is in use, heat will be generated when the electrical components are working, and the sealed equatorial mount controller cannot effectively dissipate the heat, which causes the temperature inside the equatorial mount controller to rise. The temperature affects the resistivity, and in severe cases affects the numerical control accuracy of the controller, so that the polar axis is not aligned, resulting in erroneous observation data.

The outer wall of the fixed frame contacts the bottom of the top cover, and an anti-skid groove is provided in the wall of the fixed knob, and the anti-skid groove is arranged in a ring array with the central axis of the fixed knob as the axis. The anti-skid groove provided on the fixed knob increases the roughness of the surface of the fixed knob, thereby increasing the friction between the fixed knob and the finger when twisting, so that the fixed knob is not easy to slip and is easier to twist, and the first rotating shaft is externally connected to a motor to provide power for the rotation of the air inlet blades.

The heat dissipation mechanism blows air from the inside to the outside and discharges it through the heat dissipation holes, thereby taking away the heat on the heat conductive sheet and dissipating the heat for the electrical components.

The second rotating shaft 52 is externally connected to a motor to provide power for the rotation of the heat dissipation blades 53.

[0026] The wall of the bottom plate 1 is provided with heat dissipation holes 11, and the heat dissipation holes 11 are symmetrically arranged along the central axis of the bottom plate 1. The outer wall of the bottom plate 1 is fixedly connected with a heat conductive sheet 12, and the heat conductive sheet 12 is arranged in a linear array along the central axis of the bottom plate 1. The top of the heat conductive sheet 12 is fixedly connected with a fixing plate 13. The wall at the top of the top cover 2 is provided with an air inlet hole 21, and the wall of the top cover 2 is provided with a connecting hole 22, and the connecting hole 22 is located inside the control terminal 3. The heat dissipation holes 11 are used for the heat dissipation mechanism 5 to discharge air, the heat conductive sheet 12 is used to quickly conduct the heat emitted by the components on the fixing plate 13 to the heat conductive sheet 12, and the air inlet hole 21 is the air inlet channel of the air inlet mechanism 4.

[0027] The air inlet mechanism 4 includes a fixed frame 41, the outer wall of the fixed frame 41 is fixedly connected with a cross fixing rod 42, the outer wall of the cross fixing rod 42 is rotatably connected with a first rotating shaft 43 through a bearing, the outer wall of the first rotating shaft 43 is fixedly connected with an air inlet blade 44, and the air inlet blade 44 is arranged in a ring array with the central axis of the first rotating shaft 43 as the axis, and the inner wall of the fixed frame 41 is threadedly connected with the inner wall of the top cover 2 through a fixed knob 45.

[0028] Working principle:

[0029] When in use, the bottom plate 1 is fixedly connected to the top cover 2 by bolts, and the control terminal 3 controls the operation of the electrical components on the fixed plate 13. The interior of the control terminal 3 has a connecting hole 22 opened on the top cover 2, which is used to connect the control terminal 3 and the electrical components under the top cover 2. The equatorial mount connected to the electrical components is calibrated through the control terminal 3 to align it with the polar axis, and the heat is dissipated through the air intake mechanism 4 and the heat dissipation mechanism 5, thereby increasing the heat dissipation ventilation volume and making the electrical components dissipate heat faster.

[0030] By setting up an air intake mechanism 4, the first rotating shaft 43 on the cross fixing rod 42 is driven to rotate by a motor, thereby driving a plurality of air intake blades 44 to rotate.

The second rotating shaft 52 is externally connected to a motor to provide power for the rotation of the heat dissipation blades 53. The heat dissipation mechanism 5 blows air from the inside to the outside and is discharged through the heat dissipation holes 11. While forming an air duct with the air intake mechanism 4 to increase the ventilation volume, it takes away the heat on the heat conducting plates 12 and further dissipates the heat of the electrical components.

[0031] When the air intake mechanism 4 and the heat dissipation mechanism 5 need to be inspected or replaced, the bottom plate 1 and the top cover 2 are separated by bolts. Under the action of the threaded connection, the fixing knob 45 is turned, and with the cooperation of the anti-slip groove 451, the fixing knob 45 is moved away from the top cover 2. At this time, the fixing frame 41 can be removed for easy maintenance and replacement.
