The bottom plate of the container is made of 16MnDr steel which is low temperature resistant and easy to weld. In order to provide the possibility of helicopter lifting, the container adopts a light structure. Except for the bottom plate which is 6mm, the other plates are made of 2mm bent rib plate. The invention can meet the technical requirements of transporting the astronomical telescope to the Kunlun Station in Antarctica and installing and using it.

Description

Polar Telescope Container

technical field

The invention relates to a container, in particular to a polar telescope container used in an Antarctic astronomical observation base.

Background technique

China will build an observatory in the Antarctic ice dome A, Kunlun Station, and transport the astronomical telescope to Kunlun Station for installation and use. The transportation process is to use the Xuelong ship to transport to the Antarctic land and sea, and then use the helicopter to lift it to the ice and snow surface of the Antarctic land, and then use the snowmobile to pass through the rugged Antarctic ice and snow surface, and transport it for more than 1,000 kilometers to the inland Kunlun Station.

Kunlun Station is 4,200 meters above sea level, and is the coldest place on earth. The temperature in winter is as low as -83°C, and ordinary steel is prone to cold and brittle. However, the working conditions at the station were poor, and there was no one on duty for half a year, and the freight to the station was very high. The installation operator is prone to make mistakes here. Therefore, the container in the prior art cannot meet the technical requirements for transporting the astronomical telescope to the Kunlun Station in Antarctica and installing it for use.

Contents of the invention

The purpose of the present invention is to provide a special container for the Antarctic astronomical telescope which is suitable for use under the harsh conditions of the polar region and during transportation. The performance of the special container must meet the following conditions: 1. Low temperature resistance: able to withstand the extremely low temperature of -80°C in the special natural environment of the polar region; 2. Good seismic performance, able to withstand severe wind and waves at sea, suitable for shipping on the Xuelong During the transportation to the Antarctic, and ensure that the astronomical telescope in it is not damaged; 3. Lightweight: suitable for helicopter lifting; 4. Multi-purpose and convenient to use, reducing workload: the telescope can be reduced in the process of packing and unpacking Installation effort and reduced overall weight.

The solution for accomplishing the task of the above invention is: a polar telescope container, which is made of a box made of low-temperature-resistant steel plates, and is characterized in that the bottom plate of the container is provided with telescope fixing screws; four under the bottom plate of the container There are lifting screws at the corners; the 8 top corners of the box are respectively fixed with lifting bolts for fixing the telescope during transportation.

During transportation, the astronomical telescope is fixed on the bottom plate of the container with fixing screws; shock-absorbing pads (outsourced standard parts) are added between the astronomical telescope and the bottom plate during transportation, and are fixed by the hanging bolts at the 8 corners of the box. Tighten and fix with shock-absorbing cables (outsourced standard parts), which can protect the astronomical telescope from being damaged by sea turbulence. After arriving at the base, the astronomical telescope is placed on the observation base together with the bottom plate. The temporary shock-absorbing fixtures are removed, and the floor of the container becomes the base of the telescope. There are lifting screws at the four corners under the bottom plate to adjust the level of the telescope, and according to the amount of polar snowfall, the height of the telescope can be raised every year to prevent the telescope from being buried by snow.

The present invention has following optimization scheme:

1. The four lifting screws are reinforced with elastic oblique supports to prevent wind vibration.

2. The four lifting screws are made of low temperature resistant steel pipes.

3. A door frame is arranged on the side wall of the container body, and a single door is installed on the door frame through a hinge. The container can be used as a working room when the telescope is installed in the Antarctic.

4. In addition to the 8 corners of the box, which are respectively fixed with lifting bolts for fixing the telescope during transportation, the middle part of the upper and lower long sides of the box is respectively equipped with a lifting bolt for fixing the telescope during transportation. bolt. That is, there can be up to 12 hanging bolts for fixing the telescope during transportation.

5. The bottom plate of the container is made of 16MnDr steel which is low temperature resistant and easy to weld.

6. In order to provide the possibility of helicopter lifting, the total weight of the container (with the telescope) is less than the lifting capacity of the current helicopter, that is, less than 1.5 tons (to ensure that the telescope is less than 4 tons). The container must be of light structure, except the bottom plate is 6mm plate, and the other plates are made of 2mm bent rib plate.

The invention is a special container specially designed to meet the technical requirements of transporting the astronomical telescope to the Antarctic Kunlun Station and installing it for use. The performance of this special container can withstand the extremely low temperature of -80°C in the special natural environment of the polar region, has good seismic performance, and can withstand severe wind and waves at sea. It is not damaged and suitable for helicopter lifting; after arriving at the base, the bottom plate of the container can become the base of the telescope, and the box body can be used as a working room; in the process of packing and unpacking, it can reduce the workload of installing the telescope and reduce the total weight. Easy to use.

Fig. 1 is a structural representation of the present invention;

Figure 2 is a partial enlarged view of the corner of the box.

Embodiment 1, polar telescope container, with reference to Fig. 1, Fig. 2: the base plate of container 1 is provided with telescope fixing screw; The four corners below the base plate are provided with lifting screw rod 2; There are hanging bolts 3 for fixing the telescope in transportation. The four screw rods for lifting are reinforced with elastically elastic support 4 to prevent wind vibration. Four screw rods 2 of lifting adopt the steel pipe of low temperature resistance to make. A door frame is provided on the side wall of the container body of the container, and a single door 5 is installed on the door frame by a hinge. The container can be used as a working room when the telescope is installed in the Antarctic. The bottom plate of the container is made of 16MnDr steel which is low temperature resistant and easy to weld. The container must be of light structure, except the bottom plate is 6mm plate, the other plates are made of 2mm bent rib plate, and the weight is less than 1.5 tons.
