[0002] In the field of aviation industry and high-performance power system research and development, turbojet engines, as core power units, require precise testing of their performance parameters for improving engine efficiency, optimizing structural design, and ensuring flight safety. Turbojet engines need to obtain oxygen from the outside environment during operation, and the oxygen content in the intake air directly affects the engine's combustion efficiency and emissions, making it a core external parameter for turbojet engine operation.

[0003] Existing turbojet engines generally do not have an oxygen content adjustment module designed during pre-shipment testing. The engine's air intake mainly relies on the natural air in the test space, which is not sufficiently adjustable. At the same time, during actual operation, aircraft equipped with turbojet engines experience insufficient oxygen content in the air intake at different altitudes, resulting in different operating conditions. This makes the testing in the test space unable to accurately test the operating conditions of the turbojet engine in actual use, and the accuracy of the testing is insufficient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-Figure 5 As shown, this embodiment provides an oxygenation module, including a fixed box 1. The fixed box 1 is provided with an oxygenation mechanism 2 for supplying air with different oxygen contents to a turbojet engine. The oxygenation mechanism 2 is electrically connected to a control mechanism 3 provided in the fixed box 1.

[0028] The oxygen supply mechanism 2 includes an installation assembly installed in the fixed box 1. The installation assembly is equipped with an oxygen supply component for supplying air with different oxygen contents. The oxygen supply component outputs air with different oxygen contents to the turbojet engine.

[0029] The installation assembly includes several fixing blocks 21 fixedly installed at the bottom of the inner cavity of the fixing box 1. A first drive module is provided in the fixing block 21. The first drive module is connected to the fixing disk 22 slidably connected to the fixing block 21. The oxygen supply assembly is fixed by the fixing module provided in the fixing disk 22.

[0030] This utility model discloses an oxygenation module that can provide air with different oxygen contents to the turbojet engine during testing, thereby simulating different operating conditions and recording operating parameters. A fixed box 1 serves as the foundation for the device, with all other components integrated within it, improving the device's integration and facilitating movement and adjustment. A control mechanism 3 controls the oxygenation mechanism 2 to prepare air with different oxygen contents according to set parameters, which is then supplied to the turbojet engine. The installation component is located within the fixed box 1, allowing the oxygenation component to move within the box, facilitating locking and movement, and enabling convenient loading, unloading, and maintenance. A fixing block 21 is fixed to the bottom of the inner cavity of the fixed box 1, and a first drive module drives a fixing disk 22 to slide horizontally on the top of the fixing block 21, adjusting the position of the oxygenation component for easy loading, unloading, and maintenance. The entire device is modularly integrated within the fixed phase, allowing for easy disassembly and replacement of components such as the oxygenation mechanism 2 and the installation component, reducing maintenance costs and difficulty. This utility model has a compact structure, high integration, and is easy to maintain and repair. It can operate stably for a long time and provide air with different oxygen contents to simulate different operating parameters, ensuring the normal operation of the turbojet engine and improving the accuracy of the simulation.

[0031] In one embodiment of this application, the fixed box 1 includes a box body 11, and a partition 12 is provided inside the box body 11. The fixing mechanism is installed on the partition 12 to isolate the partition 12 from the oxygen supply mechanism 2 and reduce mutual interference.

[0032] In one embodiment of this application, the open side of the box 11 is provided with an openable and closable box door 13, which can conveniently protect the internal structure after the box door 13 is closed.

[0033] In one embodiment of this application, the bottom of the housing 11 is provided with several feet 14 to facilitate the fixing of the housing 11.

[0034] In one embodiment of this application, the side wall of the housing 11 is provided with several ventilation openings to facilitate ventilation inside and outside the housing 11 and prevent the high temperature generated by the equipment from affecting the operation of the equipment.

[0035] Further optimizing the design, the first drive module includes a first drive groove 23 formed on the fixed block 21. A first drive screw 24 is rotatably connected within the first drive groove 23. The first drive screw 24 extends out of the fixed block 21 and is connected to a drive motor 25 mounted inside the fixed housing 1. A first drive block 26 is threadedly connected to the first drive screw 24. The first drive block 26 extends out of the first drive groove 23 and is fixedly connected to the bottom end of the fixed disk 22. The first drive groove 23 is designed as an inverted T-shaped structure. The drive motor 25 drives the first drive screw 24 to rotate within the first drive groove 23, causing the first drive block 26 threadedly connected to the first drive screw 24 to translate within the first drive groove 23. This, in turn, causes the fixed disk 22 to slide on the top of the fixed block 21, moving the oxygenation assembly within the fixed housing 1 and adjusting the position of the oxygenation assembly.

[0036] To further optimize the design, two guide grooves 27 are symmetrically arranged on both sides of the first drive groove 23 on the fixed block 21. A guide block 28 is slidably connected within the guide groove 27, extending out of the guide groove 27 and fixedly connected to the bottom end of the fixed disk 22. The two inverted T-shaped guide grooves 27 are symmetrically arranged on both sides of the first drive groove 23. The guide block 28, fixed to the bottom end of the fixed disk 22, slides within the guide grooves 27, thereby limiting the position of the fixed disk 22 and improving its stability.

[0037] The design is further optimized. The fixing module includes a fixed clamp 29 and a movable clamp 210. The fixed clamp 29 is fixedly connected to the fixed disk 22, and the movable clamp 210 is slidably connected to the fixed disk 22 via a second drive module. The oxygen supply component is clamped between the fixed clamp 29 and the movable clamp 210. The oxygen supply component is designed so that the fixed clamp 29 and the movable clamp 210 are located within the fixed disk 22. The fixed clamp 29 provides positioning, while the movable clamp 210 slides within the fixed disk 22 under the drive of the second drive module. This allows oxygen supply components of different sizes and specifications to be fixed within the fixed disk 22, adapting to different specifications and models of oxygen supply components and improving the device's adaptability.

[0038] In a further optimized design, the opposing surfaces of the fixed clamp 29 and the movable clamp 210 are provided with arc-shaped contact surfaces 211. Several clamping blocks 212 are hinged to the contact surfaces 211, and these clamping blocks 212 abut against the outer wall of the oxygen supply assembly. The opposing surfaces of the fixed clamp 29 and the movable clamp 210 are configured as arc-shaped contact surfaces 211, with several hinged clamping blocks 212 on the contact surfaces 211. The angle of the clamping blocks 212 can be deflected according to the specifications of the oxygen supply assembly being contacted, increasing the fixation of the oxygen supply assembly and improving the stability of the fixation.

[0039] In one embodiment of this application, the contact surface 211 between the clamping block 212 and the oxygenation assembly is provided with anti-slip texture to prevent slippage.

[0040] In a further optimized design, the second drive module includes a second drive groove 213 formed within the fixed plate 22. A second drive screw 214 is rotatably connected within the second drive groove 213. The second drive screw 214 is drive-connected to a second drive block 215 slidably connected within the second drive groove 213. The second drive block 215 extends out of the second drive groove 213 and is drive-connected to the movable clamp 210. The second drive screw 214, rotatably connected within the second drive groove 213, can drive the second drive block 215 to slide within the second drive groove 213, thereby driving the movable clamp 210 to translate, facilitating the clamping and releasing of the oxygenation assembly.

[0041] In one embodiment of this application, the second drive screw 214 may be driven by an electric motor or manually. Those skilled in the art can choose according to their needs, and this will not be elaborated here.

[0042] The oxygen supply system is further optimized by including independently configured oxygen cylinder 216, air cylinder 217, and oxygen cylinder 218. The outlet of oxygen cylinder 218 is connected to the turbojet engine. The inlet of oxygen cylinder 218 is connected to both oxygen cylinder 216 and air cylinder 217. Air with different oxygen contents, mixed in oxygen cylinder 216, is supplied to the turbojet engine for operation. Oxygen cylinder 216, air cylinder 217, and oxygen cylinder 218 are fixed in a fixed plate 22 by a fixed clamp 29 and a movable clamp 210, respectively. Oxygen cylinder 216 stores high-concentration oxygen, while air cylinder 217 stores air with lower oxygen content. Oxygen cylinder 216 and air cylinder 217 are connected to oxygen cylinder 218 via a connecting pipe 219, allowing for the preparation of air with different oxygen contents in oxygen cylinder 218 for convenient supply to the turbojet engine.

[0043] In one embodiment of this application, an oxygen content sensor and a flow sensor are provided on the oxygen cylinder 218 to control the oxygen content and flow rate of the air supplied by the oxygen cylinder 218, simulating the operating parameters of a turbojet engine.

[0044] In one embodiment of this application, a first solenoid valve 220 is provided on the connecting pipe 219. The first solenoid valve 220 can be opened and closed under the control of the control mechanism 3 to control the communication between the oxygen in the oxygen supply cylinder 216 and the air in the air cylinder 217.

[0045] Further optimizing the design, the control mechanism 3 includes a control component housed within the fixed housing 1, which is electrically connected to a lighting lamp 33 also housed within the fixed housing 1. The control component includes a control module 31 and a power supply module 32 mounted on the partition 12. The power supply module 32 supplies power to the equipment, while the control module 31 controls the automatic operation of the equipment, enabling it to run according to set parameters.

[0046] In one embodiment of this application, the power supply module 32 can be directly connected to electricity or can use a rechargeable battery, and those skilled in the art can choose according to their needs.
