Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of telescope protection, and particularly relates to a waterproof and dustproof heat preservation environment protection device which can follow the pitching of a telescope. BACKGROUND

[0002] Ali original gravitational wave detection experiment (AliCPT for short) is the first original gravitational wave experiment project in China. The original gravitational wave is generated at the beginning of the birth of the universe, and the AliCPT-1 telescope is used for measuring the B mode polarization of the cosmic microwave background (CMB). Detecting it will have important scientific significance for verifying the inflation theory and bounce theory and exploring the origin and evolution of the universe. The telescope will be erected at the AliCPT observation station in Ali, Tibet, China, at an altitude of 5250 meters. During the pitching and azimuth scanning observation of the telescope, the environmental protection cover follows the movement and protects the telescope from water, dust and heat.

[0003] In the prior art, an organ cover is usually used to protect the telescope. However, in order to meet the strength requirement of the protection cover, the frame layer of the organ cover needs to be thick and many. When the telescope pitches to the limit, the space occupied by the organ cover is too large, and the telescope cannot reach the required pitching range. Therefore, it is of great significance to design a protection cover which can meet the pitching angle of the telescope, occupies small space after folding, and does not rub and interfere with the telescope. SUMMARY

[0004] The application aims to provide a waterproof and dustproof heat preservation environment protection device which can follow the pitching of a telescope, so as to solve the above technical problems.

[0005] To this end, the application provides a waterproof and dustproof heat preservation environment protection device which can follow the pitching of a telescope, comprising:

[0006] A base is provided with a support column at the top, and a bearing is installed at the top of the support column;

[0007] A frame is a multi-layer ring-shaped foldable structure, and the middle part of the frame is connected with the bearing;

[0008] A protective cloth is wrapped outside the frame and connected with the base;

[0009] A protection cover top plate is obliquely arranged at the top of the base and supported on one side of the frame, the top of the protection cover top plate is located above the frame, the top of the protection cover top plate is connected with the protective cloth, and an observation port is formed in the protection cover top plate.

[0010] The base, the frame, the protective cloth and the protective cover top plate can effectively protect the gravitational wave detection telescope, and the position of the protective device can be adjusted to adapt to the outer contour of the telescope when the telescope is scanning and observing.

[0011] Preferably, the frame on the side close to the protective cover top plate is folded towards each other, and the frame on the side away from the protective cover top plate is arranged in layers and the frames in each layer are away from each other.

[0012] One side of the frame can be folded, and the other side is unfolded, and the protective device occupies only about 10 cm of height space when it is folded, which can effectively solve the problem of protecting the telescope and ensure that the protective cover top plate does not interfere with the telescope when the telescope is tilted by 45°-135°.

[0013] Preferably, the cross-sectional size of the frame in the upper layer is smaller than that of the frame in the lower layer.

[0014] By arranging the multi-layer frame with gradually increasing cross-sectional size, the frames in each layer can be arranged without interfering with each other, which is convenient for unfolding and storing. When the multi-layer frame is folded, if the positions close to the bearing are all squeezed in the narrow gap, the thick protective cloth can easily affect the smooth adjustment of the telescope tilt angle, and in severe cases, the frame rod can be bent and broken. The special design of the frame folding to avoid the protective cloth provides sufficient space for the folding of the protective cloth.

[0015] Preferably, the frame at the bearing position is bent towards the bearing and connected with the bearing, the side of the frame away from the protective cover top plate is inclined upward by 12°-40°, and when the side of the frame away from the protective cover top plate is inclined upward by the maximum angle, the minimum distance between the protective cover top plate and the base is 10 cm.

[0016] The frame of the present application can effectively utilize the space between the multiple frames and avoid interference, so that the frame can smoothly unfold with the protective cover outer cover cloth when unfolded, and the upward inclination of 12°-40° when folded can ensure that the telescope does not interfere with the environmental protection device when the telescope is tilted to the limit. The special angle design of the frame of the present application allows the upper frame to be nested inside the lower frame when folded, so that the frame can fall into the base layer by layer when the tilt angle is at the limit, and the protective cover can almost be attached to the base, with a distance of only the thickness of the folded protective cloth (less than 10 cm).

[0017] Preferably, the number of support columns is two, and the top of each support column is connected with a bearing, which is conducive to the unfolding and storage of the frame.

[0018] Preferably, each layer of the frame includes four articulated segments and two adjustment segments, wherein the top of each bearing is connected with two articulated segments of each layer of the frame, and the adjustment segments are connected between the ends of the two articulated segments away from the bearing.

[0019] Preferably, the hinge section comprises a bending section connected with the bearing and an extension section connected with the adjusting section, and the included angle between the bending section and the extension section is 22-70°. The bending angle design of the hinge section can further ensure that the telescope does not interfere with the environmental protection device at the limit of the pitch.

[0020] Preferably, the hinge section and the adjusting section are connected through a nut joint, and one end of the hinge section is provided with an external thread matched with the nut joint.

[0021] Preferably, one end of the hinge section is provided with a pin sleeve, and the end of the pin shaft of the adjusting section is inserted into the pin sleeve, effectively ensuring the strength and stability of the node and facilitating installation and disassembly.

[0022] Preferably, the frames of each layer are connected through a sling, and the end of the sling is connected with a thimble which is sleeved outside the rod of the frame. The distance between the frames of each layer is controlled by the length of the sling, and according to the designed distance, the frames of multiple layers are connected using the sling. When one side of the frame is stretched and unfolded, the other side of the frame naturally falls down one by one, and the protective cloth in the frame spacing is stacked layer by layer. The two frames do not pull each other, and the entire protection device pitches smoothly. The end of the sling is sleeved outside the rod of the frame by the thimble, avoiding the instability and insecurity caused by punching holes in the sling.

[0023] Compared with the prior art, the characteristics and advantages of the present application are that the present application designs a waterproof, dustproof and heat-insulating environmental protection device which can pitch with the telescope. The device has the functions of waterproofing, dustproofing and heat insulation, and can follow the movement of the telescope when the telescope is scanning. The device can protect the telescope in any state, and the protection device does not rub against or interfere with the telescope. After folding, the protective cover can almost stick to the base, and the thickness of the protection device is less than 10 cm, occupying very small space. Moreover, during the folding process, the frame and the protective cloth do not entangle, and the entire protection device pitches smoothly. BRIEF DESCRIPTION OF DRAWINGS
