DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0026] like Figures 1 to 5 As shown, an intelligent emergency repair vehicle for damaged equipment includes a drone control terminal 12, a drone 13, and a drone delivery platform 15, and also includes a plurality of modular intelligent emergency repair cabins divided according to the actual needs of emergency repair of the damaged structure;

[0027] The lower surface of the intelligent emergency repair shelter is equipped with a traction pin 2 for quick disassembly and assembly with the vehicle carrying chassis 17, and the upper surface of the shelter is equipped with a lifting ring 1 for aircraft transportation;

[0028] The intelligent emergency repair cabins include low-temperature storage cabins, drone nest cabins, intelligent command cabins, expandable activity cabins, emergency repair equipment cabins, energy storage and production cabins, and automatic robot cabins. The present invention greatly improves the application scope and flexibility of intelligent emergency repair vehicles with the help of modular design concepts. Different emergency repair cabin modules can be configured and combined according to actual emergency repair needs, and facilitates the subsequent production and technical upgrades of cabins.

[0029] The present invention standardizes the design of different modular shelters, including the length, width, height and various dimensional parameters of the shelter, and the material selection and manufacturing process of the shelter are standardized. The overall shape of the designed standardized shelter is a rectangular parallelepiped, and the shelter wall plate is made of high-strength steel. For some shelters with special needs such as low-temperature storage cabins, the materials of the shelter will be adjusted accordingly. In order to be able to use the automobile transport chassis to complete the transportation of each modular shelter of the intelligent emergency repair vehicle. A traction pin 2 for connecting to a common automobile transport chassis 17 is designed on the lower surface of the shelter, which can realize the universal applicability of the transport chassis and avoid redesigning and purchasing the automobile transport chassis. In addition, the traction pin 2 adopts a magnetically replaceable design. When there is a lack of an applicable automobile transport chassis during the emergency repair process, the traction pin 2 at the bottom of the shelter can be replaced to achieve a greater degree of universality of the transport chassis. A hoisting ring 1 is set at the four corners of the top of the shelter to meet the needs of aircraft hoisting and transportation when the forced landing environment is extremely harsh and the transport vehicle is difficult to arrive safely. The bottom of the shelter is equipped with a hydraulic support rod 7, which is used to support the shelter and adjust the shelter to a level after the shelter arrives at the emergency repair site and is deployed.

[0030] The low-temperature storage cabin, drone nest cabin, intelligent command cabin, expandable activity cabin, emergency repair equipment cabin, energy storage and production cabin, and automatic robot cabin are all equipped with solar panels 3, cabin top covers 11, and drive motors 10 for opening the cabin top covers 11. The solar panels 3 are provided with lithium iron phosphate batteries 18 in the energy storage and production cabins to store the electricity collected by the solar panels during the day, so as to provide emergency electricity supply when the cabin generator fails.

[0031] When the cabins are hoisted to the vehicle carrying chassis 17 in sequence, the cabin energy interfaces 5 between different cabins are connected through energy cables, and the cabin energy interface 5 of the cabin at the front is connected to the lithium iron phosphate battery 18 of the vehicle carrying chassis 17, so as to ensure the energy supply of each cabin during the movement of the intelligent repair vehicle and ensure the normal operation of the functions of each cabin.

[0032] When each cabin of the intelligent emergency repair vehicle is successfully transported to the emergency repair site, the lithium iron phosphate battery 18 of the vehicle carrying chassis 17 is connected to each cabin to achieve a stable energy supply during the emergency repair process. The cabin energy interface 5 is provided with overcurrent protection, leakage current protection, and lightning protection and grounding protection functions. Each cabin is provided with a cabin communication bus interface 6, which facilitates the later access of various devices in the cabin to the Internet of Things of the intelligent display emergency repair vehicle, and realizes the intelligent perception and two-way flow of vehicle information.

[0033] The low-temperature storage cabin, drone nest cabin, intelligent command cabin, expandable activity cabin, emergency repair equipment cabin, energy storage and production cabin, and automatic robot cabin are all equipped with automated robotic arms. Maintenance personnel can control the automated robotic arms through an external intelligent command terminal 9 to complete automated damage removal work on damaged aircraft.

[0034] The bottom of the low-temperature storage cabin, drone nest cabin, intelligent command cabin, expandable activity cabin, emergency repair equipment cabin, energy storage and production cabin, and automatic robot cabin are all provided with hydraulic support rods 7, which are used to support the cabin and adjust the cabin to a level after the cabin arrives at the emergency repair site and is deployed.

[0035] The left and right sides of the low-temperature storage cabin, drone nest cabin, intelligent command cabin, expandable activity cabin, emergency repair equipment cabin, energy storage and production cabin, and automatic robot cabin are all provided with side quick-connect cabinets 4 for placing various sensors of the Internet of Things. The side quick-connect cabinets 4 are provided with cabin energy interfaces 5 and cabin communication bus interfaces 6, which can realize real-time intelligent monitoring of the operating status of the intelligent emergency repair vehicle group, intelligent and automated implementation during the repair process, and intelligent and rapid repair structure design and decision-making.

[0036] The low-temperature storage cabin is used to store the repair raw materials needed in the repair process when the intelligent repair vehicle rushes to the repair site. For the repair of composite materials, the required carbon fiber composite prepreg needs to be stored at low temperature, so the designed low-temperature storage cabin needs to be able to store raw materials at various temperatures. Each of the walls of the low-temperature storage cabin is wrapped with high-temperature materials inside, and a foam insulation layer partition is designed in the middle of the cabin, dividing the cabin into left and right sides from the middle, which are the low-temperature storage room and the room temperature return room. Among them, the temperature of the low-temperature storage room is controlled at about 0 degrees Celsius by the on-board air conditioner, and two low-temperature refrigerators are installed inside. The low-temperature refrigerator must meet the requirements of long-term continuous operation. When used to store composite prepreg, the refrigerator temperature is set at about minus 18 degrees Celsius. On the side of the refrigerator, several standardized storage grids are provided for storing other repair raw materials. In the room temperature return room, a work surface and an operating table equipped with a fume hood are installed to perform the temperature return and cleaning operations of the raw materials after taking out the raw materials stored at low temperature. Among them, the low-temperature storage room is covered with thermal insulation materials on all sides and on the floor to reduce heat exchange with the outside world and ensure a constant temperature in the storage room.

[0037] The low-temperature storage cabin is provided with a low-temperature storage room and a constant temperature room. The present invention focuses on the intelligence of the repair vehicle, changes the form of the previous traditional mechanical repair vehicle, introduces many intelligent and unmanned design concepts and advanced technologies, makes the repair process assisted by the intelligent repair vehicle more standardized and intelligent, and can greatly improve the efficiency of the repair work and the repair effect of structural damage.

[0038] The temperature of the low-temperature storage room is controlled by a constant temperature air conditioner, and various prepregs used for composite material repair are stored.

[0039] The normal temperature room is used to warm up the prepreg materials taken out from the low temperature storage room, and to provide a space for local manual work under extremely harsh outdoor conditions.

[0040] The top of the drone nest cabin is provided with an openable window connected by mechanical actuation, the middle of the drone nest cabin is provided with a liftable drone landing platform 14, and other areas in the drone nest cabin are provided with storage grids 8 for storing moisture-proof boxes. The storage grids 8 in the cabin are all standardized in design, and different grids can be quickly combined and placed through magnetic contact points on the surface of the grids. At the same time, the grids are also intelligently designed. A small touch display is designed in front of the grid, which can be used to display the name of the item or equipment stored in the current grid, as well as the current usage of the item or equipment. This information is transmitted to the intelligent command terminal 9 through the cabin communication bus interface 6, so as to realize real-time storage status supervision of almost all equipment and objects on the repair vehicle.

[0041] The drone nest cabin is used to realize the take-off and landing of industrial-grade drones, and is equipped with a non-contact drone storage and charging grid 16. It is also equipped with binocular cameras and ultrasonic scanners and other non-destructive testing equipment, which can automatically complete damage detection and three-dimensional model building of damaged structures.

[0042] The intelligent command cabin is the data and control center of the intelligent repair vehicle, which is equipped with a high-performance computing terminal. The cabin is the gathering place of all cabin data buses, which is used to process the status information from each cabin, each device and even each storage grid, and realize the real-time status detection and command control of the intelligent repair vehicle. The cabin is equipped with a system interactive large screen, which is convenient for the commander to obtain the system status information in real time and quickly complete the command. The high-performance computing terminal and the system interactive large screen are used to analyze and process the real-time state information of each cabin and the external perception information, and make corresponding decisions based on this information. A communication information transmitter and signal amplifier are installed on the top of the cabin, which facilitates two-way information transmission with the dispatched drone and the repair base.

[0043] A small communication antenna and satellite communication device are installed on the top of the shelter, which can realize real-time information transmission between the repair vehicle and the repair base. After completing the non-destructive testing of the damaged parts of the aircraft, the signal transmission device of the intelligent command shelter will transmit the collected aircraft damage information to the high-performance computing terminal of the maintenance base, and use the aircraft repair structure optimization design software installed on the high-performance computing terminal to complete the design plan of the aircraft repair structure, and then transmit the design plan to the intelligent repair vehicle in the field for the next step of repair work. In addition, the shelter can also use the intelligent information of the storage grid to realize real-time supervision of the use status of almost all items and equipment on the repair vehicle, ensuring the safe and efficient repair work.

[0044] In this embodiment, the intelligent repair vehicle is also equipped with an expandable activity cabin to meet the outdoor living and activity needs of the repair personnel. The cabin is equipped with a retractable awning on the side, which can quickly form an outdoor activity venue for people to gather. The cabin is also equipped with hydraulic telescopic rods around the bottom to support and fix the activity cabin on various outdoor grounds. After the cabin is firmly supported, the electric telescopic structure designed in the middle of the cabin starts to operate. When the cabin is retracted, an activity room cabin with a width twice the width of the cabin can be formed for maintenance personnel to rest and entertain.

[0045] In this embodiment, the emergency repair equipment cabin adopts a standard cabin structure, which is mainly used for the storage of various emergency repair equipment and emergency repair items. The cabin is mainly composed of storage grids of different sizes, and various equipment and materials are stored in different areas of the cabin according to different uses, which is convenient for searching. For handheld rechargeable devices, they can be charged inside the grid, and the effect of automatic stop when full is achieved. The main equipment equipped in the cabin includes: composite material hot repair instrument, heating blanket, AC and DC argon arc welding machine, portable vise for welding, C-type ultrasonic flaw detector, eddy current flaw detector, X-ray real-time imaging system, detachable folding workbench, optical theodolite, endoscope, Leeb hardness tester, handheld vacuum cleaner type equipment. The specific equipment carried on the vehicle will be adjusted and supplemented according to the different emergency repair tasks each time.

[0046] In this embodiment, the energy cabin is used to store and produce various types of energy required during the emergency repair process to ensure the smooth progress of the emergency repair work. The interior of the cabin is divided into an energy storage area and a production area according to different functions. The energy storage area is used to store rare gas energy that is used in small quantities during the emergency repair process or is difficult to produce outdoors, and is equipped with a small lithium iron phosphate battery as an emergency power supply device for the intelligent emergency repair vehicle, wherein the gas is stored in a composite material high-pressure gas cylinder and fixed to the bottom of the cabin through a fixed base. The battery pack is charged in advance at the maintenance base, and during the emergency repair mission, the solar panels on the top of the repair vehicle and the generator located in the energy cabin are used to supplement the power. The battery pack is independent of the entire vehicle circuit in non-emergency situations. When the main generator fails, the emergency battery pack will quickly connect to the circuit to ensure the continuous energy supply of the emergency repair vehicle. The energy production area is mainly used to generate the electric energy needed in the repair process, and to provide a stable power supply for each cabin and equipment on the repair vehicle through the equipped transformer. In this embodiment, a diesel generator is used for power generation, and a three-phase four-wire system is adopted. The power supply is led to the cabin to the distribution box after the lightning protection and leakage protection switch. The distribution box supplies power to various electrical equipment such as air-conditioning equipment, task equipment, lighting equipment, ventilation equipment, and monitoring and shooting equipment. The power supply system is provided with a total power supply switch, which has overcurrent protection, leakage current protection, and lightning protection and grounding protection functions. In addition, considering the huge noise during the power generation process, the cabin is wrapped with sound insulation sponge all around, and the cabin is placed away from the cabin where people live or stay. Various styles of power interfaces are designed on the front of the energy cabin to meet some temporary power needs outside the cabin.

[0047] In this embodiment, the robot automatic shelter is the main execution part of the intelligent emergency repair vehicle. In order to provide a larger working rotation space for the robot arm, the top and side of the shelter are removed and a semi-open design is adopted. Among them, the automated robotic arm is installed on the left side of the shelter, which can realize automatic three-dimensional movement. By replacing the device at the end of the robotic arm, the robotic arm can be used to complete automated drilling, grinding, welding, and patch pasting operations. These operation instructions are all issued by the intelligent command shelter, and the execution of the repair process is completed by the robot software program designed in advance. In addition, a digital twin model of the automated robotic arm is established, which can realize real-time monitoring of the execution status of the robotic arm, and verify the correctness of the instruction through simulation before the instruction is executed, thereby ensuring the safe and accurate execution of the execution process. A small hoisting device is installed on the right side of the shelter for the hoisting of materials and equipment during the preparation of the emergency repair vehicle and the hoisting operation of maintenance personnel during the emergency repair process.

[0048] When the drone 13 needs to take off, the drone delivery platform 15 first transports the drone 13 to the drone landing platform 14 located in the middle of the cabin. The drone landing platform 14 will slowly rise upwards driven by the motor. At the same time, the open cabin top cover 11 will be opened. When the drone landing platform 14 rises to the designed height, the gripper fixing the drone is released, and the drone 13 is controlled by the drone control terminal 12 to take off. The drone nest cabin is equipped with drone storage and charging grids 16 for storing and charging drones.

[0049] The drone nest cabin mainly includes three types of drones, namely detection drones, non-destructive testing drones and tethered lighting drones.

[0050] When the repair vehicle is driving to the repair site, the top cover of the engine nest can be opened during the movement of the vehicle to release the detection drone to detect the road ahead, and the road conditions ahead can be transmitted to the intelligent command cabin of the intelligent repair vehicle in real time through the communication device. The on-board artificial intelligence or commander can determine the next driving route based on the road conditions.

[0051] When the repair vehicle is about to arrive at the forced landing location, a high-precision non-destructive testing drone is dispatched in advance to inspect the damaged parts and establish a three-dimensional damage model, which speeds up the damage detection and completes the repair structure design and actual execution.

[0052] When emergency repair work is carried out at night, the cabin can also release a tethered lighting drone, which can be hovered above the emergency repair area to provide a clear and bright working environment for the repair work, further speeding up the repair work.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and the specification only describe the principles of the present invention.
