Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides a technical solution: such as Figures 1-5As shown, an experimental device for simulating an aviation battery temperature detector includes an experimental chamber 1. A temperature control chamber 2 is fixedly installed on the bottom wall of the experimental chamber 1. A movable seat 6 is slidably connected inside the experimental chamber 1. An electric telescopic rod 7 is fixedly installed on the top surface of the movable seat 6. A placement frame 8 is fixedly installed at the bottom end of the electric telescopic rod 7. Each outer side of the placement frame 8 has a through groove 24. A detector body 23 is detachably installed on the bottom wall of the placement frame 8. A sealing plate 25 is fixedly installed on the outer side of the placement frame 8. A second sealing ring 26 is fixedly installed on the bottom surface of the sealing plate 25. An opening is opened on the top surface of the temperature control chamber 2. Multiple spring telescopic rods 14 are symmetrically installed on the top wall of the temperature control chamber 2. A mounting plate 15 is installed at the bottom end of the multiple spring telescopic rods 14. A sealing column 13 is fixedly installed on the top surface of the mounting plate 15 and inserted into the opening. A first sealing ring 16 is fixedly installed on the outer side of the sealing column 13. A temperature control mechanism is provided inside the temperature control chamber 2.

[0023] Furthermore, the temperature control mechanism includes multiple heating modules 17, which are symmetrically installed on the bottom wall of the temperature control chamber 2. Multiple temperature sensors 19 are installed on the bottom wall of the temperature control chamber 2, and a temperature controller 18 is fixedly installed on the bottom wall of the temperature control chamber 2. A circulation mechanism is provided on the outside of the temperature control chamber 2, and a cooling module 5 is fixedly installed on the outside of the experimental chamber 1. The circulation mechanism is connected to the cooling module 5. It should be noted that the heating module 17 can be a PTC heating element or a resistance wire heater, which can provide rapid heating capability. The cooling module 5 can be a compressor refrigeration unit, which can achieve rapid cooling. Through the circulation mechanism, cold or hot air can be quickly filled into the temperature control chamber 2 to complete the temperature increase or decrease. The temperature controller 18 can be a PID temperature controller, which can receive the electrical signal from the temperature sensor 19 and dynamically adjust the power of the heating module 17 and the cooling module 5 to achieve temperature control.

[0024] Furthermore, the circulation mechanism includes a second gas collecting box 4 and a first gas collecting box 3, both of which are fixedly installed on the outside of the experimental chamber 1. The second gas collecting box 4 is connected to the temperature control box 2. The bottom of the second gas collecting box 4 is fixed and connected to a first pipe 10 and a second pipe 11, respectively. Solenoid valves 12 are installed on both the first pipe 10 and the second pipe 11. The second pipe 11 is connected to the refrigeration module 5. The other end of the refrigeration module 5 and the first pipe 10 are both connected to the first gas collecting box 3. A fan 9 is fixed and connected to the outside of the temperature control box 2, and the fan 9 is connected to the first gas collecting box 3. It should be noted that the solenoid valve 12 can be used to cool or refrigerate the temperature control box 2 according to the actual usage scenario.

[0025] Furthermore, the moving mechanism includes a drive motor 20, which is fixedly mounted on the side wall of the experimental chamber 1. The output shaft of the drive motor 20 is connected to a threaded rod 21 via a coupling, and the threaded rod 21 is threadedly connected to the moving seat 6.

[0026] Furthermore, a limiting rod 22 is fixedly installed on the side wall of the experimental chamber 1, and the limiting rod 22 is slidably connected to the movable seat 6. The limiting rod 22 can limit the movable seat 6, preventing it from rotating and thus allowing it to slide linearly.

[0027] Furthermore, the placement rack 8 is located directly above the opening of the temperature control box 2, and the drive motor 20 is a conical rotor motor.

[0028] This utility model provides a simulation experimental device for an aviation battery temperature detector. The specific working principle is as follows: First, the user opens the sealed door of the experimental chamber 1 and drives the threaded rod 21 to rotate by starting the drive motor 20. In this way, the moving seat 6 is moved with the cooperation of the limiting rod 22. The moving seat 6 drives the placement rack 8 to move to the opening of the experimental chamber 1, so that the user can install the detector body 23 in the placement rack 8. Then, the drive motor 20 is started to reverse, driving the moving seat 6 to reset and making the placement rack 8 directly above the opening of the temperature control chamber 2.

[0029] Next, the electric telescopic rod 7 can be activated to drive the placement frame 8 to descend, and pressure is applied to the top of the sealing column 13 through the bottom surface of the placement frame 8, thereby driving multiple spring telescopic rods 14 to stretch their built-in springs, and adjusting the mounting plate 15 and the first sealing ring 16 to slide downward. When the second sealing ring 26 abuts against the top surface of the temperature control box 2, the first gas collecting box 3 stops driving the placement frame 8 to slide downward, and the temperature control box 2 is sealed again through the second sealing ring 26. At this time, the scene experiment can be carried out on the detector body 23.

[0030] When simulating the operation of the battery during takeoff, the temperature inside the temperature control box 2 can be rapidly increased by multiple heating modules 17, and the hot air inside the temperature control box 2 can be drawn out by the fan 9 and then enter the temperature control box 2 again through the second air collection box 4 and the first air collection box 3 in sequence, so as to quickly make the temperature inside the temperature control box 2 uniform. Then the detector body 23 located inside the temperature control box 2 can detect the continuous increase in temperature, thereby simulating the operation of the battery during takeoff.

[0031] When the battery is in cruise mode, the temperature inside the temperature control box 2 needs to be kept constant. The temperature controller 18 and temperature sensor 19 detect the temperature inside the temperature control box 2 in a timely manner. When the temperature rises, the solenoid valve 12 on the second pipe 11 can be opened, and the solenoid valve 12 on the first pipe 10 can be closed. This allows air to be cooled by the cooling module 5 and enter the temperature control box 2, thereby cooling the temperature inside the temperature control box 2. The temperature controller 18 adjusts the power of the cooling module 5 and the heating module 17 in a timely manner to ensure that the temperature inside the temperature control box 2 remains constant, thus simulating the temperature changes when the battery is in cruise mode.

[0032] Meanwhile, when in the landing state, the heating module 17 can be stopped to supply heat, and the solenoid valve 12 on the first pipe 10 can be closed, allowing air to pass through the cooling module 5 and cool down the temperature inside the temperature control box 2, thereby simulating the temperature drop of the battery. Through the above test, the working condition of the battery can be fully simulated, and the working condition of the detector body 23 can be tested.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
