Description

Technical Field

[0001] The invention relates to the technical field of waterproof performance testing equipment, in particular to a waterproof grade testing equipment for aviation obstruction lights. Background Art

[0002] As an important device to ensure the safety of aircraft, the protection level of aviation obstruction lights must meet strict standards to ensure stable operation under adverse weather conditions. The waterproof level of aviation obstruction lights is usually required to reach IP55 or higher, which means that the lights can prevent foreign objects and dust from entering, and can also prevent water ejected from the nozzle in all directions from entering the electrical appliances and causing damage.

[0003] The rain test device is a key device for testing the waterproof performance of aviation obstruction lights. By simulating rain impacts of different intensities and angles, it is possible to evaluate whether the waterproof ability of the light meets the predetermined standards. This test not only includes direct water spray tests, but may also include long-term exposure of the light to a humid environment to observe its durability and reliability.

[0004] Chinese patent CN108362443B discloses a multi-angle waterproof lamp test device capable of simulating different environments, comprising a bottom plate, both sides of the top of the bottom plate are fixedly connected to a box body through support columns, the bottom of the inner wall of the box body is fixedly connected to a fixed frame through support rods, and both sides of the fixed frame are threadedly connected to threaded rods, and the opposite ends of the two threaded rods are fixedly connected to fixed blocks. The present invention relates to the technical field of lamp test equipment. The multi-angle waterproof lamp test device capable of simulating different environments can adjust the use position of the DC nozzle and the spray nozzle in the test, so as to perform a comprehensive waterproof test on the lamp, improve the test effect, and through the selective use of the DC nozzle and the spray nozzle, it can simulate the use performance and service life of the lamp under different water flow rates, thereby improving the practicality of the device, and through the coordinated use of the solar simulator, the heating block and the refrigerator, it can test the use performance and service life of the lamp under light, high temperature and low temperature.

[0005] As shown in the above patent, the existing lamp waterproof performance test device often sets a box door on the front wall of the test box. During the test, the lamp is put in and taken out by opening and closing the box door. However, since the test process needs to simulate the rain environment, the test is carried out by spraying water towards the lamp, and water droplets will inevitably splash on the box door and the inner wall of the test box. When the box door is opened, these water droplets may drip on the laboratory floor, which not only affects the cleanliness of the floor, but also causes a waste of water resources.

[0035] See also Figures 6 to 9 In the embodiment of the present invention, a rotating seat 21 is fixedly connected to one side of the top cover 3, and the rotating seat 21 is rotatably connected to the mounting plate 2 through a rotating shaft 22. The rotating shaft 22 is fixedly connected to the rotating seat 21, and the rotating shaft 22 is rotatably connected to the mounting plate 2.

[0036] In this embodiment, preferably, the transmission mechanism includes an adjustment plate 23, a roller 25, an elastic pull rope 24 and a push plate 26. The top of the adjustment plate 23 is fixedly connected to the rotating shaft 22. A notch is provided at the bottom of the mounting plate 2. The adjustment plate 23 is arranged in the notch. The adjustment plate 23 can be rotated 90° to the right in the notch. The bottom end of the adjustment plate 23 extends into the test cavity 103. The roller 25 is rotatably installed at the bottom end of the adjustment plate 23. An elastic pull rope 24 is fixedly connected to one side of the bottom of the adjustment plate 23. One end of the elastic pull rope 24 away from the adjustment plate 23 is fixedly connected to the bottom wall of the mounting plate 2. The push plate 26 is arranged below the roller 25, and the push plate 26 contacts the roller 25. An adjustment component for adjusting the position of the push plate 26 is provided in the test cavity 103; the adjustment component includes a slide plate 27, a guide column 28, a third guide rail 32 and a push block 35. A plurality of guide posts 28 are fixedly installed at the bottom end of the plate 2, and the guide posts 28 pass through the slide plate 27, and the guide posts 28 and the slide plate 27 are slidably matched, and a limit plate 29 is fixedly installed at the bottom end of the guide posts 28, and a second spring 30 is sleeved on the guide posts 28, and the bottom end of the second spring 30 is fixedly connected to the limit plate 29, and the top end of the second spring 30 is fixedly connected to the slide plate 27, and the push plate 26 is fixedly connected to the slide plate 27, and a second traction rope 31 is fixedly connected to the bottom end of the slide plate 27, and the third guide rail 32 is fixedly installed at the bottom of the inner cavity of the test cavity 103, and a third slider 33 is slidably installed in the third guide rail 32, and the bottom end of the second traction rope 31 is fixedly connected to the third slider 33, and an adjusting rod 34 is fixedly installed on one side of the third slider 33, and a push block 35 is fixedly installed on the side wall of the test bench 4, and the push block 35 is located just above one end of the adjusting rod 34;The transmission mechanism is provided with two groups, which respectively drive the two top covers 3 to rotate. When the test bench 4 is located at the bottom of the inner cavity of the test chamber 103, the push block 35 presses on the end of the adjusting rod 34, so that the third slider 33 is located at the bottom position of the inner cavity of the third guide rail 32. At this time, the second traction rope 31 pulls the slide plate 27 so that the second spring 30 is in a compressed state, so that the push plate 26 does not produce pressure on the roller 25. At this time, under the pulling force of the elastic pull rope 24, the adjusting plate 23 is in a vertical state, so that the top cover 3 is in a horizontal state to close the top opening of the test box 1. When the test bench 4 moves upward, the test bench 4 drives the push block 35 to move upward. When the push block 35 moves upward, the push block 35 releases the lock on the adjusting rod 34, so that the third slider 33 can slide upward, so that the bottom end of the second traction rope 31 moves upward. At this time, under the elastic force of the second spring 30, the slide plate 27 moves upward, so that The push plate 26 moves upward, and when the push plate 26 moves upward, it squeezes the roller 25, so that the adjustment plate 23 rotates rightward, thereby driving the top cover 3 to rotate upward 90° through the rotating shaft 22, so that the top cover 3 is automatically opened. When the test bench 4 descends, after the push block 35 presses on the adjustment rod 34, the adjustment rod 34 drives the third slider 33 to move downward, and the third slider 33 drives the slide plate 27 to move downward through the second traction rope 31, thereby driving the push plate 26 to move downward. When the push plate 26 moves downward, the roller 25 is squeezed, so that the adjustment plate 23 is reset under the tension of the elastic pull rope 24, so that the top cover 3 is automatically closed. Through the above-mentioned structure, the transmission mechanism can automatically open the top cover 3 when the test bench 4 rises, and automatically close the top cover 3 when the test bench 4 descends, which improves the convenience of operation, and does not require the electrical drive element of the equipment to drive, which reduces the cost and improves the synchronization. ;

[0037] Working principle: During the test, the test bench 4 is driven to rise by the driving mechanism. As the test bench 4 rises, the transmission mechanism drives the top cover 3 to rotate 90° and open. Since the length of the second guide rail 15 is less than the length of the first guide rail 12, the sliding stroke of the second slider 16 is less than the sliding stroke of the first slider 11. When the second slider 16 slides upward to the limit position, the second slider 16 stops sliding, so that the cross plate 9 stops rising, and the first slider 11 continues to drive the test bench 4 to move upward, so that the cross plate 9 and the test bench 4 are separated from each other. The cross plate 9 is pulled upward by the first traction The rope 8 pulls the slide 5 to move, thereby compressing the first spring 6. When the slide 5 slides, the multiple clamps 7 move away from each other, and then the aviation obstruction light can be placed between the multiple clamps 7. As the test bench 4 moves downward, the cross plate 9 and the test bench 4 approach each other. At this time, under the elastic action of the first spring 6, the slide 5 drives the clamps 7 to move toward the aviation obstruction light, so that the multiple clamps 7 clamp the aviation obstruction light, and the top cover 3 is driven to close through the transmission mechanism, and then the multiple spray heads 17 spray toward the aviation obstruction light, thereby performing a waterproof test on the aviation obstruction light;

[0038] At the same time, when the test bench 4 moves upward, the test bench 4 drives the push block 35 to move upward. When the push block 35 moves upward, the push block 35 releases the lock on the adjusting rod 34, so that the third slider 33 can slide upward, so that the bottom end of the second traction rope 31 moves upward. At this time, under the elastic force of the second spring 30, the slide plate 27 moves upward, so that the push plate 26 moves upward. When the push plate 26 moves upward, it squeezes the roller 25, so that the adjusting plate 23 rotates right, thereby driving the top cover 3 to rotate 90° upward through the rotating shaft 22, so that the top cover 3 is automatically opened. When the test bench 4 descends, after the push block 35 presses on the adjusting rod 34, the adjusting rod 34 drives the third slider 33 to move downward. The third slider 33 drives the slide plate 27 to move downward through the second traction rope 31, thereby driving the push plate 26 to move downward. When the push plate 26 moves downward, the squeezing of the roller 25 is released, so that the adjusting plate 23 is reset under the pulling force of the elastic pull rope 24, so that the top cover 3 is automatically closed.
