Detailed Description

The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1 to 4, an embodiment of the present invention proposes a pull-out cap shelter, including a base plate 1, and further including:

the shelter body 101 is arranged on the bottom plate 1, the shelter body 101 comprises a working cabin 2 arranged on the bottom plate 1 and an equipment cabin 3 sleeved on the working cabin 2, and the equipment cabin 3 is slidably arranged on the bottom plate 1;

the driving component is arranged between the working cabin 2 and the equipment cabin 3 and is used for adjusting the equipment cabin 3 to enable the equipment cabin 3 to move along the length direction of the working cabin 2 so as to enable the equipment cabin 3 to be contained in the working cabin 2 or to move to one side of the working cabin 2;

and a locking assembly arranged between the bottom plate 1 and the equipment compartment 3 and used for fixing the equipment compartment 3.

In the embodiment of the present invention, the shelter body 101 is formed by the independent working cabin 2 and the equipment cabin 3, during initial production, the influence caused by continuous production can be reduced, when the working cabin 2 and the equipment cabin 3 are installed, by installing both the working cabin 2 and the equipment cabin 3 on the base plate 1 and connecting the working cabin 2 with the base plate 1 in a fixed manner, bolts or welding can be adopted in the fixed manner, when the equipment cabin 3 is installed, the inner diameter of the equipment cabin 3 is larger than the outer diameter of the working cabin 2, so that the equipment cabin 3 can be directly sleeved in the working cabin 2, the working cabin 2 and the equipment cabin 3 adopt a sliding sleeve manner, when target measurement equipment (such as a radar and an antenna) needs to be installed on the base plate 1, the area of the base plate 1 for installing the measurement equipment needs to be completely exposed, and the equipment cabin 3 slides on the working cabin 2 until being completely accommodated on the working cabin 2 along the length direction of the working cabin 2, so that the area of the base plate 1 for installing the measurement equipment can be rapidly exposed.

Based on other use conditions, the equipment cabin 3 is not only stored on the working cabin 2 when the target measurement equipment is installed, for example, when the antenna is used for working, the antenna cannot be blocked by other objects, and the periphery of the antenna can be hollowed out after the equipment cabin 3 is stored on the working cabin 2 so as to be used for measurement; for example, when the installed measuring equipment is maintained and overhauled, in order to expand the space around the target measuring equipment, the equipment cabin 3 can be stored on the working cabin 2, the area of the bottom plate 1 for installing the measuring equipment is completely displayed, and the equipment cabin 3 slides on the working cabin 2, so that even if the area of the bottom plate 1 for installing the measuring equipment is completely displayed, other redundant space can not be occupied, the whole structural size of the square cabin body 101 can not be increased, and the influence of the installation environment can not be caused.

Secondly, under the effect of drive assembly, when adjusting equipment compartment 3, can be automatic come to adjust equipment compartment 3, the equipment compartment 3 is accomodate to work on the cabin 2 in order to install, adjust, maintain and use equipment fast to the equipment compartment 3 is restored fast, protects the measuring equipment who installs on bottom plate 1, avoids receiving external erosion.
