Technical Field

[0001] The utility model relates to the field of air circulation machines, in particular to an aircraft air circulation system tuning device. Background Technique

[0002] The air cycle machine (ACM) is the core component of the air conditioning system, mainly composed of a compressor, a turbine, a fan, etc. The high-temperature and high-pressure bleed air from the engine passes through the primary heat exchanger in the double-stage heat exchanger, and after preliminary cooling, it enters the compressor of the air cycle machine, increasing the pressure and temperature of the air flow. Then, it passes through the secondary heat exchanger in the double-stage heat exchanger, and after further cooling, it enters the turbine, reducing the pressure and temperature to meet the requirements of the aircraft air conditioning, and at the same time driving the compressor and the fan to work.

[0003] There are still certain deficiencies in the traditional aircraft air circulation system tuning device during use: the air cycle machine may encounter various faults during use, such as severe erosion on the surface of the fan blades, wear of the nozzle assembly, etc. When inspecting and repairing the nozzle ring and the fine nozzle holes on it, it is difficult for maintenance personnel to clearly see the defects on the inner surface of the nozzle ring. Usually, they need to manually hold a lighting device to operate, which is rather inconvenient. Secondly, when repairing various components, various types of dirt are likely to adhere to the repair table, and it is time-consuming and laborious for subsequent users to clean it up.

[0004] Therefore, it is necessary to provide a new aircraft air circulation system tuning device to solve the above technical problems. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide an aircraft air circulation system tuning device that can effectively illuminate the internal structure of the nozzle ring conveniently and can automatically clean the dirt on the repair table.

[0006] To solve the above technical problems, an aircraft air circulation system tuning device provided by the utility model includes: a base and a lighting assembly. A support member is fixedly connected to the upper surface of the base, and a repair table is fixedly connected to the top of the support member. A through groove is opened at the center position of the surface of the repair table. The lighting assembly includes a top plate, the top plate is matched with the through groove, a cylinder body is fixedly connected to the bottom of the top plate, a second cylinder is fixedly connected inside the cylinder body, the output end of the second cylinder is rotatably connected with a plurality of first connecting rods evenly distributed around the axis, and a plurality of side grooves evenly distributed around the axis are opened on the surface of the cylinder body. The ends of the plurality of first connecting rods all extend to the outside of the cylinder body through the side grooves on the adjacent side.

[0007] The bottom surface of the top plate located outside the cylinder body is provided with a plurality of chutes evenly distributed around the axis. The number of the chutes matches the number of the first connecting rods. A slider is slidably connected inside the chutes.

[0009] Through the above technical solution, when overhauling each component, various types of dirt are easily adhered to the traditional repair table of the air circulation machine, and it is time-consuming and laborious for the user to clean it. Therefore, the device is specifically designed with a cleaning assembly that can automatically perform cleaning. During use, the driving motor drives the movable member to move back and forth on the reciprocating lead screw, and the pump body pumps the cleaning liquid in the water tank into a plurality of spray heads. The spray heads spray the cleaning liquid onto the repair table, and the cleaning brush on one side thereof will brush the surface of the repair table. The sewage generated by the brushing will enter the collection boxes on both sides for recycling. This structural design reduces the labor intensity of the workers and makes the design more user-friendly.

[0010] As a further solution of the present utility model, a communicating vessel is fixedly connected to the surface of the mounting member at a position on one side of the cleaning brush. A plurality of spray heads arranged at equal intervals are provided at the bottom of the communicating vessel. The communicating vessel is connected to a water tank through a delivery pipe.

[0011] Through the above technical solution, the cleaning liquid in the water tank is conveyed to the spray heads through the cooperation of the water tank and the pump body, and then evenly sprayed onto the repair table, facilitating the brushing work of the reciprocating cleaning brush.

[0012] As a further solution of the present utility model, a pump body is installed on the surface of the delivery pipe. An observation plate is arranged on the side wall surface of the water tank. The observation plate is made of a transparent material. A water injection pipe is communicated with the top of the water tank.

[0014] As a further solution of the utility model, a tool table is arranged at a position on one side of the repair table. A plurality of the tool tables are longitudinally distributed, and the plurality of tool tables are fixedly connected through fixing plates.

[0015] Through the above technical solution, the structure is also provided with a plurality of tool tables longitudinally distributed for placing various maintenance tools or components such as blades.

[0016] As a further solution of the utility model, a limiting rod is arranged at a position on one side of the reciprocating lead screw. The limiting rod is fixedly connected to the repair table. The moving part is slidably connected to the limiting rod, and a driving motor is installed at one end of the reciprocating lead screw.

[0017] Through the above technical solution, by making the moving part slidably connected to the limiting rod, the moving part can perform stable horizontal translation, and the structural design is reasonable.

The support part is fixedly connected with a first cylinder through a connecting block, and the output end of the first cylinder is fixedly connected to the bottom of the bottom plate.

[0019] Through the above technical solution, when inspecting and repairing the nozzle ring and the fine nozzle holes on it, it is difficult for maintenance personnel to clearly see the defects on the inner surface of the nozzle ring. Usually, it is necessary to manually hold a lighting device to operate. Therefore, the device is specifically provided with a lighting component. When in use, the nozzle ring is placed outside the top plate, and the first cylinder is started to drive the bottom plate to rise. At this time, several lighting lamps are turned on. The lighting lamps can illuminate the entire inner surface of the nozzle ring, eliminating the need for manual holding of lighting, which is more convenient and labor-saving. At the same time, the angle of the lighting lamps can be adjusted to adapt to nozzle rings of different sizes. When adjusting, the second cylinder is started, and the output end of the second cylinder extends, thereby driving the first connecting rod. The first connecting rod pushes the slider to move inside the chute, so that the slider can push the lighting lamp through the second connecting rod to change its angle. This structure can drive multiple groups of lighting lamps to adjust the angle at the same time, and the design is reasonable.

[0046] The first step: When inspecting and repairing the nozzle ring and the fine nozzle holes on it, it is difficult for maintenance personnel to clearly see the defects on the inner surface of the nozzle ring. Usually, it is necessary to manually hold a lighting device to operate. Therefore, the device is specifically provided with a lighting assembly 2.

The lighting lamps 25 can illuminate the entire inner surface of the nozzle ring. There is no need for manual holding of lighting, which is more convenient and labor-saving. At the same time, the angle of the lighting lamps 25 can be adjusted to adapt to nozzle rings of different sizes. When adjusting, the second cylinder 19 is started, the output end of the second cylinder 19 extends, and then drives the first connecting rod 23. The first connecting rod 23 pushes the slider 21 to move inside the chute 20, so that the slider 21 can push the lighting lamp 25 through the second connecting rod 26 to change its angle.
