Abstract
Description
Technical Field
[0001] The present invention relates to the field of security technology, and specifically to an auxiliary device for testing airport radar transmitters. Background Art
[0002] The need to test radar transmitters mainly comes from the following aspects: First, to ensure that the radar system can meet the design requirements and usage standards in actual applications; second, to discover potential problems existing in the radar system and provide a basis for subsequent debugging and optimization; third, to evaluate the working ability and accuracy of the radar system under various conditions, including ranging, speed measurement, angle measurement, and anti-interference ability. In the test of radar transmitters, signal generation and processing is a key link. The test system generates radar signals of various modulation forms through a standard signal source, such as fixed carrier frequency, linear frequency modulation, phase coding, etc. These signals are processed by the transmitter and radiated through the antenna. At the same time, the test system also needs to receive and process the output signals of the transmitter to evaluate the performance indicators of the transmitter. This includes spectrum analysis of signals, demodulation of pulse modulation signals, and evaluation of the performance of the transmitter channel. When assisting in the test of airport radar transmitters, a camera device is required for auxiliary testing. However, there are still some deficiencies in the existing camera mounting bases for assisting in the test of airport radar transmitters. For example, it is difficult to fixedly install cameras of different sizes for auxiliary testing. Summary of the Invention
[0003] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides an auxiliary device for testing airport radar transmitters, which has the advantages of automatic fixed installation and timed cleaning, and solves the problem of difficult fixed installation of cameras of different sizes.

Buffer seats are fixedly connected to both the left and right sides of the bottom end inside the box body, and fans are provided at the upper ends of both the left and right surfaces of the box body. A trigger plate is movably connected to the middle position of the upper surface of the support plate, and a variable resistor is embedded and installed at the left side position of the trigger plate inside the support plate.
[0005] As an optimization, movable sliders are slidably connected to the interiors of the mounting crossbars, and connecting vertical bars are slidably connected to the upper surfaces of the mounting crossbars. Movable connecting rods are movably connected to the upper surfaces of the movable sliders, and adjusting plates are fixedly connected to the lower surfaces of the movable sliders. Support springs are arranged on the outer sides of the adjusting plates, and electromagnet buffer seats are arranged below the adjusting plates. Fixed boxes are fixedly connected to the upper surfaces of the electromagnet buffer seats, and the adjusting plates are slidably connected to the interiors of the fixed boxes.

When the connecting rotating wheels rotate, the movable push blocks are driven to move horizontally with a gap through the deflecting rods.
[0007] As an optimization, adjusting gears are fixedly connected to the middle positions of the upper surfaces of the steering gears, connecting rotating wheels are meshed and connected to the inner side surfaces of the adjusting gears, deflecting rods are movably connected to the outer sides of the upper surfaces of the connecting rotating wheels, movable push blocks are movably connected to the inner ends of the deflecting rods, cleaning plates are fixedly connected to the inner side surfaces of the movable push blocks, limiting plates are fixedly connected to the inner side surfaces of the connecting blocks, and telescopic rods are fixedly connected to the outer side surfaces of the connecting blocks.

[0009] As an optimization, a sealing cover is arranged on the upper surface of the box body, and a perspective window is embedded and installed at the middle position of the sealing cover.
[0010] The present invention has the following beneficial effects: 1. For the airport radar transmitter test auxiliary device, when the lower end of the camera contacts the trigger plate and drives the trigger plate to slide downward, the conducting rod at its lower end slides downward along the lower end of the variable resistor. At this time, the external power supply supplies power to the electromagnet, and the magnetic induction intensity of the electromagnet increases. Magnetic blocks are fixedly connected to the lower surfaces of the adjusting plates, and the magnetic poles of the adjacent ends of the magnetic blocks and the electromagnet are the same.

The movable push block is slidably connected to both sides of the surface of the sealing cover, and cleaning plates are fixedly connected to the inner sides of the movable push blocks. When the movable push block moves horizontally, the outer surface of the perspective window is cleaned by the cleaning plates. BRIEF DESCRIPTION OF THE DRAWINGS
