Description

Technical Field

[0001] The present invention relates to a storage device for flight equipment after batch delivery, and in particular to an oxygen-isolated intelligent storage life extension system. Background Art

[0002] After being mass-produced and put into use, flight equipment faces long-term warehouse storage. The storage period of some equipment can reach more than 20 years.

[0003] The normal warehouse storage environment only restricts the storage temperature and humidity environment, while the components and non-metallic materials of flight equipment are slowly oxidized and corroded by oxygen molecules in the air. This factor is an important reason that restricts the overall life of flight equipment. The traditional method of extending storage life is to identify products or raw materials with short lifespans through expensive storage or life tests, and replace them during the overhaul period. This method is not only costly and has a long maintenance cycle, but the product replacement solution does not fundamentally solve the problem of extending storage life, resulting in a large amount of resource waste for this type of equipment. Summary of the invention

[0004] In view of the current status of the above-mentioned prior art, the purpose of the present invention is to provide an oxygen-isolated storage and life extension system, which not only isolates the flight equipment from oxygen during the storage period, fundamentally prevents the various components of the flight equipment (such as rubber, composite materials, components, etc.) from being slowly oxidized and corroded by oxygen, thereby improving the storage life of the flight equipment, but also has functions such as environmental monitoring, intelligent control, remote control, alarm monitoring, etc., and is also convenient for electrical performance testing, rolling, etc. of the flight equipment during the storage period.

[0005] Specifically, the present invention provides an oxygen isolation type intelligent storage life extension system, including: a sealed cabin, an inert gas filling device, an air pressure detection device, an oxygen concentration detection device, a temperature control and detection device, a humidity control and detection device, a camera device, an electrical switching device, a display control and alarm device and a remote monitoring device. Among them, the sealed cabin is used for sealed storage of storage targets (such as flight equipment); the inert gas filling device provides inert gas or other chemically inactive gases to the sealed cabin as needed (such as based on the results of the air pressure detection device and the oxygen concentration detection device). Other components are all arranged on the sealed cabin, connecting the inside and outside of the cabin to respectively realize the detection, display, transmission and controlled adjustment of relevant parameters in the sealed cabin. The display control and alarm device and the remote monitoring device, according to the detection parameter feedback of each component, respectively realize the display and control of the inert gas filling device, the air pressure detection device, the oxygen concentration detection device, the temperature control and detection device, the humidity control and detection device, the camera device and the electrical switching device.

[0006] The sealed shelter includes: the shelter main structure, shelter cover, sealing ring, adapter and lifting assembly. To ensure the sealing effect, the shelter main structure has a rectangular shape and is formed in one piece on five sides, and holes are opened at appropriate positions to facilitate the installation and connection with other devices (such as gas filling, connector lead-out and control interface display, etc.), as well as the exhaust of gas (air exhaust valve); the shelter cover is used to close the lid after the flight equipment is placed; the sealing ring is used to seal the shelter main structure and the shelter cover after the lid is closed, as well as the sealing at the opening; the adapter is used to adapt the storage target (flight equipment) to the structure of the interior space of the shelter, and plays a role in fixing and vibration reduction; the lifting assembly is located outside the shelter, which can facilitate the lifting and rolling of the entire shelter.

[0007] Among them, the inert gas filling device includes: inert gas storage tank and filling pipeline. The inert gas storage tank is used to store inert gas, and can also store chemically inactive gases such as nitrogen; the filling pipeline provides a physical channel for the gas in the gas storage tank to be filled into the cabin; the inert gas filling device cooperates with the air pressure detection device to detect the air pressure of the gas in the sealed cabin and inject gas accordingly.

[0008] The air pressure detection device is used to detect the air pressure of the gas in the sealed cabin, and is equipped with a digital communication interface to facilitate the transmission of the measurement results so as to control the inert gas filling device to implement gas injection.

[0009] Among them, the oxygen concentration detection device can use a mature industrial product oxygen concentration detector, which is mainly composed of a sensor and a transmitter related circuit, and has a digital communication interface to facilitate the transmission of measurement results.

[0010] In this regard, in order to ensure that the air pressure inside the sealed cabin remains relatively stable during the inert gas injection process, the method of injecting inert gas while exhausting the original air in the cabin is usually adopted, and at the same time, an oxygen concentration detection device is used to detect the oxygen concentration. When it is detected that the oxygen concentration in the cabin is lower than the specified value, the injection of inert gas can be stopped and the air exhaust valve can be closed.

[0011] The temperature control and detection device includes: a compressor, a condenser, an evaporator, a four-way valve and a temperature sensor. The compressor, condenser and evaporator cooperate to achieve temperature regulation: in the refrigeration mode, the compressor is used to compress the gaseous refrigerant into a high-temperature and high-pressure state, and then send it to the condenser to dissipate heat and become a liquid refrigerant at room temperature and high pressure. The evaporator is used to vaporize the liquid refrigerant and absorb heat, ultimately achieving the purpose of lowering the temperature. The four-way valve is used to switch between the cooling and heating modes; the temperature sensor is used to detect the temperature in the sealed cabin, and can transmit the detection data through the interface display or data bus.

[0012] The humidity control and detection device includes: humidification equipment, dehumidification equipment and humidity detector. The humidification equipment atomizes water into micron-sized ultrafine particles through ultrasonic high-frequency oscillation to increase the internal humidity when the humidity in the cabin is too low; the dehumidification equipment cools down the evaporator to condense and dehumidify the water vapor in the gas when the humidity in the cabin is too high; the humidity detector is used to sense the humidity inside the cabin and can transmit the detection data through the interface display or data bus.

[0013] Among them, the camera device can use mature industrial products. The camera device is installed in various corners or key positions inside the cabin, which is convenient for observing and photographing the status of stored targets (flight equipment) in the cabin when the cabin is sealed, and it has a lighting fill light function.

[0014] Among them, the electrical transfer device includes: the external connector of the square cabin and the transfer cable. The external connector of the square cabin integrates the power input node and various mainstream bus nodes currently used by flight equipment, such as 1553B, SRIO, RS422, RS485, CAN, ETHERNET, LVDS and optical fiber interfaces, as well as various input and output command interfaces, and has sufficient channel margins reserved; the transfer cable is used to realize the transfer and interconnection between the external connector of the square cabin and external equipment (such as the plug-in connector installed on the missile). Through the electrical transfer device, the electrical interface of the loaded flight equipment can be led out to the outside of the square cabin, which is convenient for the periodic verification and maintenance testing of the flight equipment.

[0015] Among them, the display control and alarm device includes: a display controller, an alarm and a sensor bus input interface. On the one hand, the display controller is used to display status parameters, such as the current status of the stored flight equipment, which may include: model, number, production date, manufacturer, and the current temperature, humidity, air pressure, oxygen concentration, etc. in the cabin; on the other hand, the display controller also has a touch screen control function, which can manually set the qualified range of the cabin temperature, humidity, air pressure and oxygen concentration outside the cabin, as well as manually operate heating and cooling, humidification and dehumidification, inert gas perfusion, etc.; the alarm can use sound and light alarms to give an alarm prompt when the cabin status exceeds the specified range; the sensor bus input interface is used for data communication between this device and the temperature sensor, humidity detector and oxygen concentration detection device.

[0016] Among them, the remote monitoring device includes: Ethernet line, remote computer and terminal display and control program / software. The Ethernet line is used to realize the command and data interaction between the cabin and the remote computer; the remote computer is used to run the terminal display and control software, which can realize all the functions of the above-mentioned display and control device and camera display, etc. The remote monitoring device can remotely realize the batch detection and management tasks of the status of flight equipment in multiple cabins. Through a humanized, concise and efficient view, it can simultaneously display the various states of the monitored cabins, remotely control the changes in temperature, humidity, air pressure and oxygen concentration in the cabin, and issue an alarm when key indicators are abnormal.

[0017] The advantages of an oxygen isolation type intelligent storage life extension system provided by the present invention are:

[0018] 1) By storing flight equipment in an inert gas sealed environment, oxygen-sensitive electronic components and non-metallic materials (such as rubber, etc.) in the flight equipment are completely isolated from oxygen during long-term storage, fundamentally solving the weak link of storage life extension of some components in the flight equipment and improving the storage life of the entire flight equipment;

[0019] 2) The sealed cabin used in the present invention cooperates with various components to detect temperature, humidity, air pressure and oxygen concentration. Compared with the traditional storage environment, it not only realizes more complete physical quantity detection, but also makes each parameter independently controllable;

[0020] 3) The design of the shelter fully considers the electrical performance test, hoisting and transportation, and engine rolling operations during the storage period. For this purpose, the relevant electrical and structural features are specially designed to improve the convenience of use;

[0021] 4) Through the remote monitoring function, efficient detection and management of the status of multiple flight equipment in the warehouse can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
