Description

Technical Field

[0001] The present invention relates to the technical field of radar antennas, and in particular to a large radar antenna cabin. Background Art

[0002] Large radar antenna pods typically range from several to tens of meters in length and are usually stationary. When exposed to solar radiation, the temperature difference between the illuminated and shadowed areas is significant, leading to a large temperature gradient within the pod. If the pod's insulation is inadequate, temperature-sensitive equipment within the pod will not function properly, impacting the pod's telecommunications performance. Summary of the Invention

[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a large radar antenna cabin.

[0004] The present invention provides a large radar antenna cabin, comprising:

[0005] A cabin body, one side of the cabin body being a reflective surface with a reflective plate installed, and the other side opposite to the reflective surface being a reflective back side with a cabin door installed;

[0006] A partition door is provided inside the cabin, and the interior space of the cabin is divided into a constant temperature insulation zone located on the side of the partition door close to the reflective surface and a common insulation zone located on the side of the partition door close to the back reflective surface via the partition door.

[0007] Preferably, the partition door is provided with ventilation shutters.

[0008] Preferably, the partition door is a heat-insulating door.

[0009] Preferably, the space of the constant temperature insulation zone is smaller than the space of the common insulation zone.

[0010] Preferably, the cabin includes a supporting frame, an outer skin fixed to the outside of the supporting frame, an inner skin fixed to the inside of the supporting frame, and a thermal insulation layer located between the outer skin and the inner skin.

[0011] Preferably, the inner skin is made of non-metallic material, and a heat insulating layer is provided on the side of the inner skin away from the heat insulating layer.

[0012] Preferably, the thermal insulation layer is thermal insulation foam adhered to the surface of the inner skin.

[0013] Preferably, the insulation layer of the cabin body located in the constant temperature insulation zone is formed by spraying and stacking a foaming agent in layers, and the insulation layer located in the common insulation zone is formed by pasting multiple layers of insulation foam.

[0014] Preferably, the supporting skeleton includes transverse beams and longitudinal beams constituting an outer frame, and the transverse beams and longitudinal beams are both hollow structures, and are filled with thermal insulation materials.

[0015] Preferably, the heat-insulating material inside the transverse beam and the longitudinal beam is formed by foaming a foaming liquid.

[0016] This invention employs a partition door within the cabin, which divides the interior space into a constant-temperature insulation zone near the reflective surface and a normal insulation zone near the door. The constant-temperature insulation zone is used to house equipment sensitive to temperature gradients, ensuring that these devices maintain a suitable constant temperature. The normal insulation zone is used to house other equipment and to ensure the passage and work of personnel. This structural design not only meets the telecommunications performance requirements of temperature-gradient-sensitive equipment but also reduces insulation design costs.

[0026] Reference Figure 1-2The present invention proposes a large radar antenna cabin, comprising: a cabin body 1, one side of the cabin body 1 being a reflective surface with a reflector 2 installed, and the other side of the cabin body 1 opposite to the reflective surface being a reflective back surface with a cabin door 3 installed. A partition door 4 is provided inside the cabin body 1, and the partition door 4 is a heat-insulating door, and divides the internal space of the cabin body 1 into a constant temperature insulation zone 1a located on the side of the partition door 4 close to the reflective surface, and a common insulation zone 1b located on the side of the partition door 4 close to the reflective back surface. During operation, the constant temperature insulation zone 1a is used to place equipment that is sensitive to temperature gradients to ensure that the relevant equipment is at a suitable constant temperature; while the common insulation zone 1b is used to place other equipment that has no requirements for temperature gradients and provides a working space for staff.

[0027] In a further embodiment, the space of the constant temperature insulation zone 1a is smaller than the space of the common temperature insulation zone 1b.

[0028] Reference Figure 3 The partition door 4 is provided with ventilation louvers 5 so that ventilation and heat exchange can be carried out between the constant temperature insulation area 1a and the common insulation area 1b.

[0029] Reference Figure 4-6 The cabin 1 includes a support frame 11, an outer skin 12 fixed to the outside of the support frame 11, an inner skin 13 fixed to the inside of the support frame 11, and an insulation layer 14 located between the outer skin 12 and the inner skin 13. The specific installation method is as follows:

[0030] The outer skin 12 can be fixed to the support frame 11 by riveting or welding, and then the insulation material 6 is set between the frame of the support frame 11 and the outer skin 12 to form an insulation layer 14. Finally, the inner skin 13 is screwed or riveted to the support frame 11 to form a large antenna cabin with insulation function.

[0031] Reference Figure 7 In a further embodiment, the inner skin 13 is made of a non-metallic material with a large thermal resistance coefficient. After the inner skin 13 is riveted, thermal insulation foam is added on the side away from the thermal insulation layer 14 to form a thermal insulation layer 15. This can isolate the thermal bridge of the metal support frame 11 and prevent heat from diffusing inward.

[0032] Reference Figure 8-9In a further embodiment, the insulation layer 14 of the cabin 1 located in the constant temperature insulation zone 1a is formed by spraying and stacking a foaming agent in layers, while the insulation layer 14 located in the normal insulation zone 1b is formed by gluing together multiple layers of insulation foam. The insulation layer 14 in the constant temperature insulation zone 1a is sprayed with a foaming agent to achieve a layer-by-layer stacking of the insulation material 6. This results in a continuous and dense insulation layer 14 in the constant temperature insulation zone 1a, with strong intra- and inter-layer adhesion, resisting debonding and exhibiting excellent insulation performance. The insulation layer 14 in the normal insulation zone 1b is gluing together multiple layers of insulation foam, achieving better insulation performance. Compared to spraying a foaming agent, this method saves processing costs and time, and requires less manual skill and expertise.

[0033] In a further embodiment, the support frame 11 includes transverse beams and longitudinal beams forming an outer frame. The transverse beams and longitudinal beams are hollow structures and are filled with thermal insulation material 6 to increase the thermal resistance of the cross-section of the transverse beams and longitudinal beams and form a closed thermal insulation layer 14 on the side walls, bottom wall, and bottom wall of the cabin 1.

[0034] Specifically: the heat-insulating material 6 located inside the frame is formed by foaming a foaming liquid.

[0035] As can be seen from the above, the present invention employs a partition door 4 within the cabin 1, which divides the interior of the cabin 1 into a constant-temperature insulation zone 1a near the reflective surface and a normal insulation zone 1b near the door 3. The constant-temperature insulation zone 1a is used to house equipment sensitive to temperature gradients, ensuring that these equipment maintains a suitable constant temperature; the normal insulation zone 1b is used to house other equipment and to ensure the passage and work of personnel. This structural design not only meets the telecommunications performance requirements of temperature-gradient-sensitive equipment but also reduces insulation design costs.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
