Detailed implementation mode

[0027] Now, with reference to the accompanying drawings and embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0028] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, an aircraft automatic anti-skid brake tester includes a base 1, side plates 2 fixed to both sides of the top of the base 1, a partition board 4 fixed to the inner side walls of the side plates 2 at the top of the base 1, a connecting slide plate 6 provided on the top of the base 1, a second rotating shaft 7 provided inside the partition board 4, a wheel mounting seat 8 provided at one end of the second rotating shaft 7, and a brake device 11 provided on the outer wall of the partition board 4. It further includes: an environment simulation structure 9, the environment simulation structure 9 is provided at the bottom end of the wheel mounting seat 8, the environment simulation structure 9 includes a third motor 901 provided at the bottom of the base 1, a lifting screw rod 902 fixed to the top of the third motor 901, a simulated ground block 903 provided on the outer wall of the lifting screw rod 902, and a wind and rain simulator 904 installed on the inner side wall of the side plate 2. The third motor 901 and the lifting screw rod 902 are symmetrically distributed at the bottom end of the wheel mounting seat 8. The lifting screw rod 902 is threadedly connected to the simulated ground block 903. A water outlet is provided at the top of one side of the wind and rain simulator 904 close to the wheel mounting seat 8, and an air outlet is provided at the middle position of the wind and rain simulator 904.

[0029] It should be noted that due to the different sizes of the wheels, the heights between the wheels and the simulated ground block 903 are also different. By providing the environment simulation structure 9, when the third motor 901 is started, it drives the lifting screw rod 902 to rotate. The rotation of the lifting screw rod 902 causes the simulated ground block 903 to move up and down on the outer wall of the lifting screw rod 902 until the simulated ground block 903 reaches the specified position. The wind and rain simulator 904 then discharges water and air according to requirements to simulate the road surface effect in rainy and windy weather.

[0030] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, a dust-proof structure 3 is provided at the top of the inner wall of the side plate 2. The dust-proof structure 3 includes a rotating base 301 fixed to the top end of the base 1 away from one side of the wheel mounting seat 8, a first rotating shaft 304 rotatably connected to the inside of the rotating base 301, a first motor 303 provided on the outer wall of the side plate 2, and a dust-proof housing 302 fixedly connected to the outer wall of the first rotating shaft 304. One end of the first rotating shaft 304 penetrates through the rotating base 301 and extends to the outside of the side plate 2 and is fixedly connected to the output end of the first motor 303.

[0031] It should be noted that during simulation, with the dust-proof structure 3 provided, starting the first motor 303 causes the first rotating shaft 304 to drive the dust-proof housing 302 to rotate on the top of the rotating base 301, realizing the opening and closing between the top end of the base 1 and the inner wall of the side plate 2, so that the base 1, the side plate 2, the dust-proof housing 302 and the partition plate 4 form a relatively airtight space, thus protecting against external dust when not in use and preventing internal water from splashing when in use.

[0032] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a moving structure 5 is provided at the bottom end of the connecting slide plate 6 on the top of the base 1. The moving structure 5 includes a moving chute 501 opened at the top end of the base 1, a moving rotating rod 502 rotatably connected to the inside of the moving chute 501, a second motor 503 provided inside the base 1, and a moving slider 504 threadedly connected to the outer wall of the moving rotating rod 502. Both ends of the moving rotating rod 502 extend to the inside of the base 1, one end of the moving rotating rod 502 is fixedly connected to the output end of the second motor 503, the top end of the moving slider 504 is fixedly connected to the connecting slide plate 6, and a sewage discharging structure 10 is provided at the bottom end of the simulated ground block 903. The sewage discharging structure 10 includes a sewage collecting tank 1001 opened at one side of the top end of the base 1, a first lower sewage tank 1002 opened at the bottom end of the sewage collecting tank 1001, a second lower sewage tank 1003 opened at the bottom end of the first lower sewage tank 1002, and a sewage discharging pipe 1004 opened at the bottom end of the second lower sewage tank 1003. The side view cross-section of the first lower sewage tank 1002 is designed as an inverted isosceles trapezoid, and the side view cross-section of the second lower sewage tank 1003 is designed as an inverted cone.

[0033] It should be noted that in the test of wind and rain conditions, there will be a large amount of water inside the test instrument. Through the sewage discharge structure 10, when the test is carried out under wind and rain conditions, the water produced by the wind and rain simulator 904 will slide along the simulated ground block 903 into the sewage collection tank 1001, gather in the first lower sewage tank 1002 and fall into the second lower sewage tank 1003, and finally be discharged through the sewage pipe 1004, realizing the cleaning of the internal sewage.

[0034] When the utility model is in use, the third motor 901 is started to drive the lifting screw rod 902 to rotate. The rotation of the lifting screw rod 902 causes the simulated ground block 903 to move up and down on the outer wall of the lifting screw rod 902 until the simulated ground block 903 reaches the specified position. The wind and rain simulator 904 then discharges water and air according to requirements to simulate the road surface effect under rainy and windy weather. The first motor 303 is started to drive the first rotating shaft 304 to drive the dust-proof shell 302 to rotate on the top of the rotating base 301, realizing the opening and closing between the top side plate 2 of the base 1 and the inner side wall, so that the base 1, the side plate 2, the dust-proof shell 302 and the partition plate 4 form a relatively closed space. When the test is carried out under wind and rain conditions, the water produced by the wind and rain simulator 904 will slide along the simulated ground block 903 into the sewage collection tank 1001, gather in the first lower sewage tank 1002 and fall into the second lower sewage tank 1003, and finally be discharged through the sewage pipe 1004, realizing the cleaning of the internal sewage.
