Description

Technical Field

[0001] This utility model relates to the field of testing and verification device technology, and in particular to a marine testing and verification device for the detection performance of airborne radar based on a ship platform. Background Technology

[0002] Marine radar is a type of radar mounted on ships for navigation, collision avoidance, ship positioning, and navigation in narrow waterways; it is also known as marine radar. Marine radar provides essential observation tools for navigators in poor visibility conditions. Its advent was a major milestone in the development of navigation technology.

[0003] When ships sail at sea, they are prone to turbulence due to the marine environment. To simulate the detection performance of airborne radar under turbulent conditions, testing and verification devices are needed. In existing technologies, airborne radar is typically placed on a swaying platform for testing; however, the simulation effect of a swaying platform is relatively limited, and its efficiency needs improvement.

[0004] Therefore, it is necessary to propose a marine testing and verification device for airborne radar detection performance based on a ship platform to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a marine testing and verification device for the detection performance of airborne radar based on a ship platform, in order to solve the problem that in the prior art, airborne radar is usually placed on a swaying platform for testing, but the simulation effect of the swaying platform is relatively simple and the efficiency of use needs to be improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine testing and verification device for airborne radar detection performance based on a ship platform, comprising a support platform mounted on top of the base frame;

[0008] The rubber pad is provided with an elastic adjustment component, which includes an inner cavity and an air bladder. The inner cavity is opened inside the rubber pad, and the air bladder is fixedly connected to the inside of the inner cavity.

[0009] The support platform is equipped with an adjustment component for adjusting the degree of airbag inflation.

[0010] Preferably, the regulating assembly includes a pump body, an air duct, and a solenoid valve. The pump body is fixedly connected to the outer wall of the support platform. One end of the air duct is connected to the pump body, and the other end of the air duct is connected to the airbag. The solenoid valve is installed on the air duct.

[0011] Preferably, the bottom of the placement plate is fixedly connected to an elastic telescopic rod, the bottom end of which abuts against the support platform, and multiple elastic telescopic rods are provided.

[0012] Preferably, a barrier is fixedly connected to the top of the placement plate.

[0013] Preferably, a swing frame is fixedly connected to the bottom of the support platform, a vertical frame is fixedly connected to the top of the base frame, and the swing frame is hinged to the top of the vertical frame.

[0014] Preferably, an electric hydraulic cylinder is hinged to the base frame, and the telescopic end of the electric hydraulic cylinder is hinged to the swing frame.

[0015] Preferably, casters are installed at all four corners of the bottom of the base frame.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1.

[0023] This utility model provides, for example Figures 1-4 The device shown is a marine test and verification device for airborne radar detection performance based on a ship platform. It includes a base frame 1, and casters 14 are installed at the four corners of the bottom of the base frame 1. The casters 14 are equipped with a braking structure to move the test and verification device to a suitable position for positioning.

[0024] To simulate the turbulence of a ship platform at sea, a support platform 2 is installed above the base frame 1. A rubber pad 3 is mounted on top of the support platform 2, and a mounting plate 4 for placing an airborne radar is fixedly connected to the top of the rubber pad 3. In actual use, the airborne radar is fixed to the mounting plate 4. When the support platform 2 swings, the rubber pad 3 will cause the mounting plate 4 to swing synchronously, producing a turbulence effect, thus simulating the turbulence of an airborne radar in a maritime environment.

[0025] Furthermore, a positioning mechanism (not shown in the figure) is provided on the top of the placement plate 4. The positioning mechanism includes structures such as clamps, which are used to fix the airborne radar on the placement plate 4.

[0026] A barrier 5 is fixedly connected to the top of the placement plate 4 to prevent the airborne radar from slipping off during the positioning process.

[0027] To increase the diversity of the swaying simulation effect, an elastic adjustment component is set inside the rubber pad 3. The elastic adjustment component includes an inner cavity 6 and an airbag 7. The inner cavity 6 is opened inside the rubber pad 3, and the airbag 7 is fixedly connected inside the inner cavity 6. When the airbag 7 is fully inflated, it provides rigid support for the rubber pad 3, and the rubber pad 3 will not deform arbitrarily. At this time, the swaying frequency of the airborne radar is consistent with the swaying frequency of the support platform 2. When the airbag 7 is contracted, there is a certain deformation space inside the rubber pad 3, and the rubber pad 3 is easy to deform and sway. At this time, the swaying frequency of the airborne radar is greater than the swaying frequency of the support platform 2, and the turbulence is more obvious. Thus, the swaying frequency can be adjusted. The more obvious the contraction of the airbag 7, the greater the swaying frequency, increasing the diversity of the swaying simulation effect and facilitating the testing and verification of the detection performance of the airborne radar.

[0028] This invention, by setting up structures such as rubber pads 3 and airbags 7, adjusts the oscillation frequency of airborne radar, increases the diversity of sway simulation effects, and improves the detection performance of airborne radar as a sea-based testing and verification device.

[0029] To adjust the inflation level of the airbag 7, an adjustment assembly for adjusting the inflation level of the airbag 7 is provided on the outside of the support platform 2. The adjustment assembly includes a pump body 8, an air duct 9, and a solenoid valve 15. The pump body 8 is fixedly connected to the outer wall of the support platform 2. One end of the air duct 9 is connected to the pump body 8, and the other end of the air duct 9 is connected to the airbag 7. The solenoid valve 15 is installed on the air duct 9. The pump body 8 can switch between air supply and suction modes. When in air supply mode, the solenoid valve 15 is opened, and air is inflated into the airbag 7 through the air duct 9. Then the solenoid valve 15 is closed. When in suction mode, the solenoid valve 15 is opened, and air is suctioned from the airbag 7 through the air duct 9. Then the solenoid valve 15 is closed.

[0030] A pressure sensor can also be installed inside the airbag 7 to monitor the pressure inside the airbag 7, thereby controlling the degree of inflation of the airbag 7.

[0031] To prevent the placement plate 4 from directly impacting the support platform 2, an elastic telescopic rod 10 is fixedly connected to the bottom of the placement plate 4. Multiple elastic telescopic rods 10 are provided, and the bottom end of the elastic telescopic rod 10 abuts against the support platform 2. When the support platform 2 swings, the bottom end of the elastic telescopic rod 10 located on the downward tilting side of the support platform 2 abuts against the support platform 2 and retracts adaptively, thereby preventing the placement plate 4 from directly impacting the support platform 2.

[0032] A swing frame 12 is fixedly connected to the bottom of the support platform 2, and a vertical frame 11 is fixedly connected to the top of the base frame 1. The swing frame 12 is hinged to the top of the vertical frame 11, allowing it to swing at the top of the vertical frame 11. An electric hydraulic cylinder 13 is hinged to the base frame 1, with its extension and retraction end hinged to the swing frame 12. Specifically, by controlling the extension and retraction of the electric hydraulic cylinder 13, the swing frame 12 is driven to swing at the top of the vertical frame 11, thereby causing the support platform 2 and other structures to swing.
