June 14, 2019 at 23:48The concept of a prefabricated tower with a dome cover mainly for astronomical observations
Astronomical observations are most often carried out from stationary shelters. Their construction is difficult when installed in mountainous areas, areas with a harsh climate. And often in such conditions, there is a favorable astroclimate. Observatories are arranged in the mountains in Antarctica. For example, China is creating the largest astronomical base there.
Extensive experience in creating domed towers was gained at the Pulkovo Observatory over many years of its activity. Yuri Sergeyevich Streletsky, the chief designer of the equipment for the main astronomical instruments of this observatory, offers an advance design of a pre-fabricated tower with a dome cover (made in the form of a layout). It, for example, can be used for observations conducted by the Arctic and Antarctic Research Institute.
Appointment
The construction is intended for use in difficult conditions in mountainous areas and / or difficult meteorological conditions in areas with harsh climates.
Device
Main components: tower 1, dome cover 2 and elevator 3.
"
The tower is mounted on a steel frame 4, secured with anchor bolts to the base, for example, rocky ground.
The supporting structure of the tower is a rotary portal, which from the original near horizontal position is brought into vertical working position by means of, for example, cable drives. The rotary portal is a parallelogram design. It consists of the following main components: bearing steel pipe 5, two rotary players and 6, a support 7.
A supporting steel pipe with a diameter of 400 mm (from the standard assortment), in the lower part, is pivotally mounted on the axes of 2 brackets 8 mounted on the frame 4. Two pivoting arms 6 of steel profiles are mounted on the axes of 2 brackets 9 mounted on the frame . The caliper 7 is connected to the 2 upper hinges 10 of the two rotary arms 6 and the upper rotary axis 11 of the support pipe 5. The
dome cover 2, which is installed on the caliper 7, contains a turntable 12, a shelter from inclined flat panels 13, a rectangular viewing slot with sliding sashes 14 formed on one of the flat panels.
An observation device 15 is installed inside the dome cover on the upper area of the carrier pipe 5 (for example, an optical astronomical instrument such as a telescope). For access to the inside of the dome cover on one of the panels on the hinges, a door 16 is installed, folding up.
The elevator 3 consists of two inclined steel profiles 17 with rail tracks and a movable carriage 18 with a guard for personnel moved by a cable drive. The bottom lift is mounted on the main steel frame 4, on top it is connected to the service platform, fixed in the lower part of the dome cover 2 directly under the door 16.
Transportation and installation
The main components are delivered, for example, by road or caterpillar vehicles. After unloading at the installation site, the frame is fixed on the base, the main nodes are connected together in the initial position. Then the lift is made from the initial to the working position by means of drives of the structure itself.
Distinctive features
Simplicity and ease of installation in inaccessible places, for example, in the Arctic, Antarctic, mountainous areas. This is achieved by lifting the tower together with the dome cover from the original to the working position. The whole structure is made of standard parts having a low cost.
Resistance to difficult meteorological conditions: strong winds, snow charges. It is provided by a narrow rectangular slit and two drive sliding flaps mounted on one of the inclined panels. Each leaf in the upper part is mounted on a hinge, in the lower part it enters the guide.
Functioning and conducting observations The
rotation of the observational instrument around the vertical axis is carried out together with the rotation of the dome cover on the turntable. The rotation of the tool around the horizontal axis is due to the drive of its mounting.
Observations are carried out mainly remotely. Periodic maintenance and adjustment of the equipment is carried out by the operator, climbing the carriage with a fence to the service platform and further into the coating through the lifting door.
The presented avan-project is designed to ensure the following requirements:
The indicated object may be of interest for astronomical expeditions in various climatic zones. It can be successfully applied both for the indicated tasks and for arranging school astronomical observatories in remote areas.
Participants in the development of the avan-project:
The author of the project is Yuri S. Streletsky, chief designer of equipment for the main astronomical instruments of the GAO.
Scientific Advisor - Senior Researcher, Arctic and Antarctic Research Institute, Ph.D. mat. Sciences Sergey Nikolaevich Shapovalov.
