Description

Technical Field

[0001] The utility model is applicable to the technical field of equipment installation and provides a support column installation structure for radar cross section testing. Background Art

[0002] Radar cross section (RCS) testing is a key technique used to evaluate and characterize an object's ability to interact with radar waves. RCS refers to the effectiveness of radar waves reflected from an object back to the radar receiver. It is closely related to the object's shape, material, and angle. This test is widely used in military, aerospace, automotive electronics, and other fields, providing crucial data support for target identification, stealth technology, and radar design. By accurately measuring a target's RCS, researchers can assess its radar reflection characteristics and optimize its design to achieve better stealth performance.

[0003] During radar cross-section testing, the rotating fine-tuning support column is a crucial component for ensuring test accuracy and data reliability. Because the radar cross section is directly related to the object's angle of incidence and observation, precise angular adjustment of the object under test is essential. This fine-tuning typically involves a drive motor rotating the support column to fine-tune the rotation of the platform on top of the column. During extended testing and fine-tuning, the drive motor is typically buried in an enclosed underground space, making it difficult to dissipate internal heat, creating safety risks.

The device includes a base, a mounting groove provided on the base, a bottom mounting seat mounted in the mounting groove, a turntable fixedly connected to the bottom mounting seat, and a support column mounted on the output end of the turntable;

[0005] A support portion, an air duct partition and an air duct outer wall are installed on the top of the base, and the air duct partition and the air duct outer wall form a hollow cavity structure; an exhaust fan is provided on the air duct partition, and an air outlet top cover and an air inlet top cover are installed on the top of the support portion and the air duct outer wall.

[0011] Furthermore, the vertical edge is made of rubber, and the upper top surface of the vertical edge abuts against the lower bottom surface of the disc.

[0012] The two air chamber heat dissipation structures of the utility model remove heat from the device. Under the condition of long-term testing and fine-tuning, the heat generated by the drive motor in the enclosed space underground can be removed, eliminating safety hazards.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See also Figure 1-5 The present invention provides a support column mounting structure for radar cross-section testing, comprising a base 1 with a mounting slot 11, within which a bottom mounting seat 01 is mounted. A turntable 02 is fixedly connected to bottom mounting seat 01, and a support column 04 is fixedly connected to the top of the output end of turntable 02. Turntable 02 can rotate support column 04 at the top. During radar cross-section testing, rotating and fine-tuning the support column is a crucial step in ensuring test accuracy and data reliability.

[0024] The top of the base 1 is fixedly connected with a support part 21 and an outer wall of the air duct 22. The base 1 is square. Two support parts 21 are fixedly connected on one side of the top of the base 1. The outer wall of the air duct 22 is installed on the opposite sides of the two support parts 21. The support part 21 and the outer wall of the air duct 22 can play a supporting role. The top of the base 1 is fixedly connected with an air duct partition 23. The air duct partition 23 and the outer wall of the air duct 22 form a hollow cavity structure, which can form an air duct while playing a supporting role.

[0025] An exhaust fan 231 is installed on the air duct partition 23. An air outlet cover 4 and an air inlet cover 3 are installed on the top of the support portion 21 and the air duct outer wall 22. Specifically, the air outlet cover 4 is mounted on the top of the support portion 21 and the air duct outer wall 22, and the air inlet cover 3 is mounted on the top of the air duct outer wall 22. An air outlet grille 41 and an air inlet grille 31 are respectively installed on the air outlet cover 4 and the air inlet cover 3.

[0026] The cavity inside the outer wall 22 of the air duct (between the air duct partition 23 and the outer wall 22 of the air duct) is the ventilation cavity 20. An equipment cavity 10 is provided between the support part 21 and the air duct partition 23. The exhaust fan 231 connects the ventilation cavity 20 with the equipment cavity 10. When the exhaust fan 231 is started, the outside air is drawn into the ventilation cavity 20 through the air inlet grille 41. The exhaust fan 231 can blow the gas in the ventilation cavity 20 into the equipment cavity 10, and then the gas is discharged from the device through the air outlet grille 41.

[0027] A disc 05 is fixedly connected to the support column 04. The rotation axis of the support column 04 coincides with the central axis of the disc 05. When the turntable 02 is working, the disc 05 can rotate together with the support column 04. The upper top surface of the disc 05 is in the same plane as the upper top surface of the air outlet cover 4.

[0028] Preferably, the bottom height of the ventilation cavity 20 is lower than the bottom height of the equipment cavity 10. When the exhaust fan 231 is working, large dust particles carried by the airflow entering the ventilation cavity 20 will fall to the bottom of the ventilation cavity 20 due to gravity and the inertia caused by the airflow velocity, and will not enter the equipment cavity 10.

[0029] Preferably, a plenum partition 24 is provided between the support portion 21 and the air duct partition 23. The plenum partition 24 corresponds to the air outlet grille 41 on the air outlet top cover 4 and divides the interior of the device into the equipment chamber 10 and the air outlet chamber 30. A through-hole is provided in the plenum partition 24, allowing communication between the equipment chamber 10 and the air outlet chamber 30. The plenum partition 24 can collect dust that falls from the air outlet grille 41. When cleaning the laboratory floor, dust particles will land on the plenum partition 24, making cleaning easier.

[0030] Preferably, the inner rim of the reserved hole 42 is provided with an inner edge 421, and a vertical edge 422 is mounted on top of the inner edge 421. The upper surface of the vertical edge 422 abuts the lower surface of the disk 05. The vertical edge 422 is made of rubber. This arrangement prevents dust from entering the device through the gap between the reserved hole 42 and the disk 05, preventing dust particles from landing on the turntable 02.

[0031] During the actual installation of this device, construction personnel will reserve a mounting position on the ground at the test site, the size of which matches the device. A threaded post is provided at the bottom of the mounting position to facilitate installation. Mounting hole 101 is provided on base 1. The post is inserted into mounting hole 101 and then threaded into a nut at the top to secure it. After adjusting the nut to precisely level base 1, caulking cement is directly applied between base 1 and the bottom of the mounting position. After installation, the top surfaces of the device's outlet cover 4 and inlet cover 3 are flush with the ground. Turntable 02 rotates to fine-tune support column 04. During this rotation, disk 05 rotates, providing a constant shielding effect on the device's interior, preventing dust from entering the device and accumulating on turntable 02, potentially damaging it.

[0032] Therefore, the device can remove the heat inside the device through its two air chamber heat dissipation structures. Under long-term testing and fine-tuning conditions, the heat generated by the drive motor in the enclosed space underground can be removed, eliminating safety hazards; at the same time, the two heat dissipation outlets respectively prevent large dust particles from contacting the turntable 02 through the unique air duct structure in the device, thereby preventing accelerated damage caused by dust accumulation on the turntable 02.

[0033] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
