Description

180-degree translation open-type intelligent astronomical dome

Technical Field

The utility model relates to an astronomical calotte especially relates to an astronomical calotte that can realize opening the space more than 180, belongs to the astronomy field.

Background

The astronomical dome is used for placing a large astronomical telescope and is generally built on a high mountain top with a wide view field or the top end of a building so as to be beneficial to astronomical observation. Current astronomical domes have skylights that can be opened and closed. When an astronomical telescope is required to observe an celestial body, the skylight is opened; when not in use, the skylight is closed. The astronomical dome body can rotate horizontally by 360 degrees and is used for multi-azimuth observation.

To date, astronomical domes have been externally crawled, clam-shell and petal from the perspective of skylights. The structural design of these astronomical domes suffers from the following drawbacks:

1. the dome is externally provided with a crawling structure skylight:

the dome is provided with a strip skylight and a skylight cover capable of sliding outside the dome, and the skylight cover crawls on the outer surface of the astronomical dome to open or close the skylight. After the skylight is opened, the skylight cover is not in close contact with the outer surface of the astronomical dome to form a movement obstacle, the skylight cover is inevitably lifted to be very high, and the gap between the inner surface of the skylight cover and the outer surface of the movable dome is very large. The astronomical dome is generally built on the top of a building or on the top of a mountain, the structure is unreasonable in areas with high wind power, and the skylight is easily turned over by wind. And in order that the inner surface of the skylight cover does not interfere with the inner surface of the dome after the skylight is closed, a large reserved gap is required to be reserved during manufacturing so as to compensate for the accumulated error of the huge skylight cover formed in the manufacturing, installation and the like processes.

2. Clam type dome and petal type dome defects:

three lamella or two lamella formula domes have very big safety problem in steel construction and mechanical mechanics design, and the origin has with the fulcrum. The dome is driven by the chassis, and due to the weight of the dome, taking an 8-meter dome as an example, the self weight is about 4 tons, the semicircular height of the 8-meter dome is a petal-shaped metal body with the height of 4 meters, and the area of the petal-shaped metal body is 33.33 square meters. The lamella formula calotte all can produce strong inertia impulsive force when starting with the stop, and lamella formula calotte lamella form metal body, the transmission all welds on fossil fragments below the calotte, fossil fragments and the chassis welding of square pipe preparation, and each lamella of lamella formula calotte only leans on the hinge to connect and hold the lift along two lift lead screw rotation axes, the bottom of lamella only leans on the welding hinged joint to connect, astronomical observation is because of earth's rotation, the calotte need be 360 rotary motion, the calotte motor starts from static to operation and rotates inertia, three 4 meters height just like the metallic flaps of sail, self nearly 1 ton is heavy self-shake when the operation, very easily cause limited lift lead screw rotation axis bending deformation and continuous use's rotation axis metal wearing and tearing, three or two can not get back to the primary site. When the two-lobe or three-lobe body is opened, a large V-shaped force arm is formed from the bottom to the top of the transmission, and the large moment and torque generated in the case of gust can also bring disastrous results to a dome and personnel. When the petal type astronomical dome is completely opened, the observation opening is a V-shaped opening, and the widest part of the zenith is less than 800 mm; and the opening from the zenith to the horizon ring is V-shaped and smaller, so that the observation at low latitude causes great obstacle to the observation visual field, and even the observation cannot be carried out. The light rays of the celestial body with a slightly low observation horizon height are largely shielded by the dome, so that the light entering the telescope is seriously reduced, and the resolution of the telescope is seriously reduced finally. In the multi-petal type astronomical dome, light rays are seriously blocked by the narrow V-shaped petal openings, and the image definition seen in a high-end astronomical telescope arranged in the dome is only equivalent to a small telescope of hundreds of yuan.

The technical contents listed in the prior art only represent the techniques mastered by the utility model, and are not regarded as the prior art for evaluating the novelty and creativity of the utility model.
