Description

Technical Field

[0001] This utility model relates to the field of lighting testing technology, specifically to an optical testing device for aviation obstruction lights. Background Technology

[0002] Aviation obstruction lights, also known as navigational lighting equipment, are special lighting fixtures used to identify obstacles. They belong to the navigational lighting equipment industry. Aviation obstruction lights are a category of lights within this industry. To distinguish them from general-purpose lighting, aviation obstruction lights are not constantly lit but flashing. Low-intensity aviation obstruction lights are constantly lit, while medium-intensity and high-intensity aviation obstruction lights flash, with a flashing frequency of not less than 20 times per minute and not more than 60 times per minute. The function of aviation obstruction lights is to display the outline of structures, enabling aircraft operators to judge the height and outline of obstacles and serving as a warning. Aviation obstruction light optical testing equipment is a professional device used to test and evaluate the performance of aviation obstruction lights to ensure that they meet aviation safety standards. This includes a strobe tester, which is an optical measuring instrument that controls the light source to flash rapidly at a specific frequency.

[0003] When conducting frequency tests on a large number of aviation obstruction lights, the light source needs to operate continuously. The light emitted by the light source will cause the temperature inside the housing to rise. When dissipating heat through ordinary heat dissipation holes, the heat dissipation efficiency is poor, and dust can easily enter the housing, which will affect the use of the corresponding electrical components.

[0004] To address this, an optical testing device for aviation obstruction lights is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an optical testing device for aviation obstruction lights.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aviation obstruction light optical testing device includes:

[0008] The housing has a light source at its front end and a transparent baffle covering the light source at its front end. The housing is fully enclosed with the transparent baffle. A base is provided at the rear end of the housing.

[0009] The PLC circuit board is located inside the housing;

[0010] A cooling assembly for cooling the interior of a housing, the cooling assembly including a condenser tube disposed within the housing;

[0011] A turbulence-dissipating component for circulating air within the housing, and a cooling component including a fan disposed within the housing.

[0012] Preferably, the side wall of the housing is also provided with a display screen, a connector, and an adjustment button, and the display screen, connector, and adjustment button are all electrically connected to the PLC circuit board.

[0013] Preferably, a water storage tank is fixedly installed at the top of the shell, and a heat exchange liquid is provided in the water storage tank. One end of the condenser extends into the water storage tank, and a water pump is fixedly installed on the side wall of the water storage tank. The inlet of the water pump is connected to the other end of the condenser, and the outlet of the water pump is connected to a water injection pipe located at the top of the water storage tank.

[0014] Preferably, a semiconductor cooling chip is fixedly installed on the side wall of the water storage tank.

[0015] Preferably, a mixing blade roller is rotatably installed inside the water storage tank, and a turbine blade is fixedly installed on the outer side of the mixing blade roller, with the end of the water injection pipe aligned with the top of the turbine blade.

[0016] Preferably, the diameter of the end of the water injection pipe gradually decreases.

[0017] Preferably, two ventilation holes are provided on both sides of the housing near the light source, and one of the ventilation holes is located on the rear side of the fan.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By setting up a cooling component, after the water pump is powered on, it drives the heat exchange fluid in the water tank to flow in the condenser tube. At this time, the heat exchange fluid in the condenser tube can exchange heat with the high-temperature air in the shell, which can lower the temperature inside the shell. This provides a suitable environment for the light source and PLC circuit board, preventing them from malfunctioning due to high temperature and extending their service life. The sealed shell also isolates dust, reducing the impact of dust on electrical components. When the heat exchange fluid flows back, the water flow can drive the turbine blades to rotate. At this time, the mixing blade roller can rotate in the water tank, driving the heat exchange fluid in the water tank to flow. This ensures that the heat exchange fluid is fully cooled by the semiconductor refrigeration chip, guaranteeing the cooling effect of the heat exchange fluid.

[0020] 2. By setting up a baffle component, the fan, together with two vents, can ensure that the air inside the casing circulates within the casing and the transparent baffle, allowing the cooled air after heat exchange to circulate and ensuring the cooling effect. Attached Figure Description

[0034] The airflow evacuation assembly is used to circulate air within the housing 1, and the cooling assembly includes a fan 11 disposed within the housing 1.

[0035] In this embodiment, when testing the frequency of the aviation obstruction light, the housing 1 is fully enclosed with the transparent baffle 3, which can prevent dust from entering the housing 1. The cooling component can cool the housing 1, and the turbulence component can circulate the cold air after heat exchange inside the housing 1, which helps to cool the housing 1.

[0036] As one embodiment of this utility model, please refer to Figure 2 The side wall of the housing 1 is also provided with a display screen 5, a connector 6 and an adjustment button 7, and the display screen 5, connector 6 and adjustment button 7 are all electrically connected to the PLC circuit board 12.

[0037] In this embodiment, after the wiring is connected through the connector 6, the display screen 5 can observe the frequency of the tested aviation obstruction light, and the adjustment button 7 can adjust the frequency of the light source 2, which facilitates the testing of the aviation obstruction light.

[0038] As one embodiment of this utility model, please refer to Figure 4 A water tank 10 is fixedly installed at the top of the shell 1. The water tank 10 contains heat exchange fluid. One end of the condenser tube 14 extends into the water tank 10. A water pump 8 is fixedly installed on the side wall of the water tank 10. The inlet of the water pump 8 is connected to the other end of the condenser tube 14. The outlet of the water pump 8 is connected to a water injection pipe 15, which is located at the top of the water tank 10.

[0039] In this embodiment, after the water pump 8 is powered on, the water pump 8 can drive the heat exchange liquid in the water tank 10 to flow in the condenser tube 14. At this time, the heat exchange liquid in the condenser tube 14 can exchange heat with the high temperature air in the shell 1, which can lower the temperature inside the shell 1 and provide a suitable environment for the light source 2 and PLC circuit board 12. This can prevent the light source 2 and PLC circuit board 12 from failing due to high temperature and can improve the service life of the light source 2 and PLC circuit board 12.

[0040] As one embodiment of this utility model, please refer to Figure 3 A semiconductor cooling chip 9 is fixedly installed on the side wall of the water storage tank 10.

[0041] In this embodiment, the cold end of the semiconductor cooling chip 9 can cool the heat exchange liquid in the water storage tank 10, which can cause the temperature of the heat exchange liquid that has risen after heat exchange to drop again, and can continuously cool the inside of the shell 1.

[0042] As one embodiment of this utility model, please refer to Figure 4 A mixing blade roller 17 is rotatably installed inside the water storage tank 10. A turbine blade 16 is also fixedly installed on the outside of the mixing blade roller 17, and the end of the water injection pipe 15 is aligned with the top of the turbine blade 16.

[0043] In this embodiment, after the water is discharged from the water injection pipe 15, the water flow can drive the turbine blades 16 to rotate. At this time, the mixing blade roller 17 can rotate in the water storage tank 10. The mixing blade roller 17 can drive the heat exchange liquid in the water storage tank 10 to flow, so that the heat exchange liquid can be fully cooled by the semiconductor cooling chip 9, and the cooling effect of the heat exchange liquid can be guaranteed.

[0044] As one embodiment of this utility model, please refer to Figure 4 The diameter of the end of the water injection pipe 15 gradually decreases.

[0045] In this embodiment, the smaller diameter water injection pipe 15 has a larger water pressure when it is sprayed out, which can provide sufficient power for the rotation of the turbine blade 16.

[0046] As one embodiment of this utility model, please refer to Figure 4 Two ventilation holes 13 are provided on both sides of the housing 1 near the light source 2, and one of the ventilation holes 13 is located on the rear side of the fan 11.

[0047] In this embodiment, the fan 11, together with two ventilation holes 13, can ensure that the air inside the housing 1 flows between the housing 1 and the transparent baffle 3, thus ensuring the cooling effect.

[0048] Working Principle: First, after connecting the wiring via connector 6, the frequency of light source 2 can be adjusted using adjustment button 7, facilitating testing of the aviation obstruction light. During testing, light source 2 operates continuously, causing the temperature inside housing 1 to rise. At this time, water pump 8 is activated. After water pump 8 is powered on, it drives the heat exchange fluid in water tank 10 to flow in condenser tube 14. The heat exchange fluid in condenser tube 14 can exchange heat with the high-temperature air inside housing 1, lowering the temperature inside housing 1. This provides a suitable environment for light source 2 and PLC circuit board 12, preventing them from malfunctioning due to high temperatures and extending their service life. The cold end of the semiconductor cooling chip 9 can cool the heat exchange fluid in the water tank 10, causing the temperature of the heat exchange fluid that has risen after heat exchange to drop again, and continuously cooling the inside of the shell 1. The heat exchange fluid can flow back into the shell 1 through the condenser pipe 14. After the water is discharged from the water pipe 15, the water flow can drive the turbine blades 16 to rotate. At this time, the mixing blade roller 17 can rotate in the water tank 10. The mixing blade roller 17 can drive the heat exchange fluid in the water tank 10 to flow, so that the heat exchange fluid can be fully cooled by the semiconductor cooling chip 9, ensuring the cooling effect of the heat exchange fluid. In addition, the fan 11, together with the two vent holes 13, can ensure that the air inside the shell 1 flows in the shell 1 and the transparent baffle 3, ensuring the cooling effect.
