[0054] Combined with appendix Figures 1-10 In one embodiment of the present invention, an airborne equipment health status monitoring device includes:

[0055] Support plate 1, installed on a civil aircraft;

[0056] Fixture 2 is installed on the top surface of support plate 1;

[0057] Oxygen cylinder 3 is clamped and fixed by bracket 2;

[0058] The fixing plate 4 is set above the fixing frame 2 and located on the side of the oxygen tank 3;

[0059] The restraint assembly 5 is mounted on the side of the fixing plate 4 around the oxygen tank 3;

[0060] The air extraction box 6 is fixedly inserted into the through hole on the side of the fixing plate 4;

[0061] The suction pipe 62 passes through the side of the suction box 6, with the box opening pointing towards the oxygen tank 3; a one-way valve with the valve port facing away from the suction cup 61 is installed inside the suction pipe 62.

[0062] Suction cup 61 is installed at the opening of the box;

[0063] The gas collection box 7 is fixed to the side of the fixing plate 4, and an oxygen concentration monitor is installed inside it;

[0064] The air outlet 71 is located on the side of the air collection box 7;

[0065] The conduit 8 is communicated with the gas inlet hole of the top surface of the gas collecting box 7, and the other end is directed to the valve of the oxygen tank 3.

[0066] Specifically, when monitoring the state of the oxygen tank 3, the fixing plate 4 is arranged on the side of the oxygen tank 3, the fixing plate 4 is horizontally bound by the binding assembly 5, the suction box 6 is sucked by the suction pipe 62, and the suction disc 61 is bound to the side of the oxygen tank 3, so that the internal gas pressure of the suction box 6 is reduced, the one-way valve in the suction pipe 62 prevents the gas leakage of the suction box 6, and thus the suction disc 61 is adsorbed to the side of the oxygen tank 3 and the suction force gradually increases, and the vertical binding of the fixing plate 4 is completed.

[0067] Then the gas inlet of the conduit 8 is aligned with the area where the oxygen tank 3 top may leak, the suction pump arranged in the conduit 8 continuously sucks the gas into the gas collecting box 7, and then the gas is sprayed out through the gas outlet 71 arranged on the side of the gas collecting box 7, the oxygen concentration monitor arranged in the gas collecting box 7 monitors the oxygen concentration of the gas sucked by the conduit 8, and then the oxygen concentration monitor uploads the oxygen concentration to the aircraft alarm system through the electrical signal, when the oxygen concentration reaches a certain value, it is detected that the oxygen tank 3 leaks, the alarm system automatically sends an alarm signal to notify the staff to take corresponding measures, realizes real-time monitoring of the state of the oxygen tank 3, and effectively avoids safety accidents caused by leakage of the oxygen tank 3.

[0068] The binding assembly 5 comprises:

[0069] The pull rope 51 is fixed at one end on the side of the fixing plate 4;

[0070] The fastening bolt 52 is fixedly connected with the other end of the pull rope 51 at the nut;

[0071] The adjusting block 53 is fixedly connected with the end of the pull rope 51 away from the fixing plate 4, and cooperates with the fastening bolt 52;

[0072] The threaded groove 54 is arranged on the side of the adjusting block 53 and is engaged with the fastening bolt 52.

[0073] Specifically, when the size of the oxygen tank 3 is different, the fastening bolt 52 in the binding assembly 5 is twisted, the fastening bolt 52 and the threaded groove 54 are engaged with each other to drive the total length between the fastening bolt 52 and the adjusting block 53 to change, and then the binding degree of the binding assembly 5 to the oxygen tank 3 is adjusted in combination with the pull rope 51, so that the oxygen tank 3 is adjusted synchronously when the size changes, the applicability of the monitoring equipment is improved, and the monitoring equipment is convenient for use for various oxygen tanks 3.

[0074] The airborne equipment health state monitoring device further comprises:

[0075] The rectangular groove 9 is arranged on the vertical inner wall of the gas outlet 71;

[0076] The blocking plate 91 is partially inserted into the rectangular groove 9 and is in sliding contact with the upper and lower inner walls of the air outlet 71.

[0077] The cam 92 is located on one side of the blocking plate 91 inside the rectangular groove 9 and has a circular arc protrusion on the side surface.

[0078] The rotating shaft 93 is movably arranged through the side surface of the rectangular groove 9 and is rotatably arranged at the center of the surface of the cam 92.

[0079] The driving motor 94 is mounted on the surface of the gas collecting box 7 and is connected to the end of the rotating shaft 93 outside the rectangular groove 9.

[0080] Specifically, when the oxygen tank 3 leaks a small amount of oxygen, the gas quickly flows out of the gas collecting box 7, making it difficult for the oxygen concentration monitor to effectively detect changes in oxygen concentration, and causing missed detection. Therefore, by inserting the blocking plate 91 into the rectangular groove 9, the driving motor 94 continuously drives the cam 92 to rotate through the rotating shaft 93. Since the cam 92 is made of a magnet and the surface of the blocking plate 91 is covered with a metal sheet, the cam 92 and the blocking plate 91 are continuously attracted to each other. As the cam 92 rotates, the arc-shaped protrusion on the side surface of the cam 92 intermittently presses the blocking plate 91 out of the rectangular groove 9, so that the blocking plate 91 intermittently blocks the air outlet 71. Therefore, the oxygen gas sucked into the gas collecting box 7 will be temporarily retained, and the gas in the gas collecting box 7 will be temporarily accumulated. The leaked oxygen gas will not immediately flow out of the gas collecting box 7, i.e., the leaked oxygen gas will be temporarily accumulated in the gas collecting box 7, so that the oxygen concentration in the gas collecting box 7 increases, thereby avoiding missed detection of the oxygen concentration monitor due to the small amount of leakage of the oxygen tank 3.

[0081] The airborne equipment health state monitoring device further comprises:

[0082] The adjusting air pipe 10 is fixedly inserted through the bottom surface of the air suction box 6 and is in communication with the air suction box 6.

[0083] The inertia plate 11 is slidably connected inside the adjusting air pipe 10.

[0084] The intercepting rod 12 is fixedly arranged inside the adjusting air pipe 10 and above the inertia plate 11.

[0085] The connecting spring 13 is fixedly arranged at the bottom surface of the inertia plate 11 and at the inner wall of the adjusting air pipe 10.

[0086] Specifically, when the oxygen tank 3 is shaken, the side suction cup 61 of the oxygen tank 3 is easy to fall off, causing the entire monitoring device to slide down on the side of the oxygen tank 3, which cannot be used. Therefore, the adjusting air pipe 10 is arranged. When the oxygen tank 3 is shaken, the adjusting air pipe 10 will vibrate synchronously. The inertial plate 11 inside the adjusting air pipe 10 will move up and down continuously due to the vibration force. When moving downward, the connecting spring 13 will be squeezed. When moving upward, the intercepting rod 12 will be hit. Therefore, the inertial plate 11 will reciprocate inside the adjusting air pipe 10, and the moving range will be larger when the vibration force is larger. When the inertial plate 11 moves downward, the communication space between the adjusting air pipe 10 and the air suction box 6 will be increased, so that the gas pressure inside the air suction box 6 is reduced, thereby increasing the adsorption force of the suction cup 61 on the side of the oxygen tank 3, reducing the risk of the suction cup 61 falling off the oxygen tank 3 due to the vibration force, and increasing the use stability of the monitoring device.

[0087] The conduit 8 is connected by two detachable air pipes, and a continuously working air suction pump is arranged inside. It is convenient for equipment installation, and the gas in the area that may leak at the top of the oxygen tank 3 is continuously sucked into the gas collection box 7.

[0088] A V-shaped air suction cylinder is arranged at the air suction port of the conduit 8. The air suction area space of the conduit 8 is increased, preventing the leaked oxygen of the oxygen tank 3 from being missed.

[0089] The cam 92 is made of a magnet, and the surface of the blocking plate 91 is coated with a layer of metal sheet, which continuously attracts the cam 92. The blocking plate 91 continuously adheres to the side surface of the cam 92 under the action of magnetic force, and moves intermittently into the air outlet 71 during the rotation of the cam 92 in combination with the arc-shaped protrusion.

[0090] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
