Description

Technical Field

[0001] The present invention relates to a design of an external field microwave rapid repair device and a connection mechanism therewith, in particular to a design of a microwave repair device for damaged components of fiber reinforced resin-based composite materials and a connection and fixing mechanism, specifically to a design and use method of an external field microwave repair device for fiber reinforced resin-based composite materials and an equipment of a self-locking connecting rod mechanism. Background Art

[0002] At present, the use of advanced fiber-reinforced thermosetting composite materials with excellent mechanical properties in aircraft has become a key technical indicator to measure the advancement of aircraft. Especially in the fields of military and civil aviation, the large-scale application of fiber-reinforced composite materials can significantly reduce the structural weight of aircraft and improve the physical properties of aircraft. At the same time, it can also greatly reduce the number of parts, simplify the assembly process, and shorten the manufacturing cycle. However, in battlefield environments, fiber-reinforced composite materials are very easy to be damaged by bird strikes, lightning strikes or bullets. The opportunity for war is fleeting, and extremely high requirements are placed on the rapid repair of damaged parts of fighter planes. However, it is difficult to quickly and efficiently complete the task of repairing damaged aircraft composite components in an external field environment. The labor required for repair is huge, and the physical fitness of the staff is extremely high.

[0003] At present, when repairing damaged composite components of aircraft in an outdoor environment, the traditional repair method is hot repair, that is, an indirect heating repair method such as laying an "electric blanket" in the area to be repaired. The patch in the area to be repaired is heated and cured in the form of heat conduction in the area to be repaired. In addition, there is a method of directly heating and curing the composite material by directly energizing the carbon fiber composite material. For example, invention patent CN108407340A discloses a repair technology that uses electrical loss to heat and cure carbon fiber reinforced resin-based composite components. However, this method requires a large amount of preparation work before repair, the repair process is relatively complicated, the repair cycle is long, the energy consumption is high, the economic benefit is poor, and the quality after repair is difficult to guarantee, and the technical requirements of the workers are high.

[0004] In recent years, some field rapid repair equipment using microwave curing technology has also appeared. For example, invention patents CN103802339A and CN105584061A both disclose a repair method for microwave curing carbon fiber reinforced composite materials by using a microwave source to generate microwave energy. However, this repair process method for carbon fiber composites is only applicable to repair operations on simple planes, and cannot solve the repair task of damaged parts of fiber reinforced composite components with variable curved surfaces. Moreover, the invention technology requires workers to work in the repair area for a long time, which consumes a lot of physical strength of the workers. For example, if the area to be repaired is located at the lower end of the wing, the workers need to press and fix the tight fit between the resonant cavity and the component to be repaired for a long time. This will not only bring serious risks of microwave leakage and cause damage to the workers' bodies, but also greatly consume the workers' physical strength. Therefore, these resonant cavity devices suitable for simple planes are difficult to be promoted on a large scale. Up to now, there is no device for repairing damaged fiber reinforced composite components that can realize repair operations for any complex curved surface and solve the problem of extremely high labor intensity of workers in repair operations. Summary of the invention

[0005] The purpose of the present invention is to design an external field microwave repair device and a method for using it to repair damaged fiber-reinforced resin-based composite components in order to solve the problem that existing composite repair equipment is difficult to apply to the repair task of fiber-reinforced composite components with complex curved surfaces, and the problem that the repair workers consume a lot of physical strength in the repair operation of fiber-reinforced composite components. By using a high-temperature resistant flexible sponge, a flexible sealing ring, and a flexible anti-leakage metal film composed of an adaptive flexible mechanism, it can effectively achieve adhesion with the surface to be repaired of the fiber-reinforced composite component with a variable curved surface, and at the same time, combined with an automatic locking device, it can conveniently and efficiently complete the positioning and fixing of the resonant cavity.

[0006] One of the technical solutions of the present invention is:

[0007] An outdoor microwave rapid repair device, comprising a multi-channel microwave transceiver antenna, a multi-degree-of-freedom hinge-link mechanism and a holding device 6, characterized in that: the holding device 6 is installed on the top of an adaptive microwave resonant cavity 14, the end of the holding device 6 is connected to the multi-degree-of-freedom hinge-link mechanism 7, and the multi-degree-of-freedom hinge-link mechanism 7 is equipped with a self-locking nut 8 for realizing the locking and positioning of the connecting rod; a cable sleeve 13, a microwave transmitting device 4 and a microwave receiving device 12 are jointly installed on the multi-channel microwave transceiver antenna of the adaptive microwave resonant cavity 14 5, the cable sleeve 13 realizes the retraction and extension of the multi-channel microwave transceiver antenna 5 by means of elastic force and manual tension; the adjustable locking collar 3, the flexible sealing ring 10, the flexible high-temperature resistant sponge 11, and the flexible metal film 2 jointly assist the adaptive microwave resonant cavity 14 to realize the adaptive installation of any variable curved surface; the magnetic locking device 16 is installed at the bottom of the multi-degree-of-freedom hinge-link mechanism 7, and the multi-degree-of-freedom hinge-link mechanism 7 can be installed, fixed, disassembled and stored on the surface of the field microwave repair instrument 9 by rotating the magnetic locking knob 15.

[0008] The present invention has a high degree of interchangeability and can be applied to the surface attachment of fiber-reinforced composite components with complex curved surfaces. The top of the center axis of the adaptive microwave resonant cavity 14 is connected to a foldable and retractable multi-channel microwave transceiver antenna 5, and is connected to a gripping device 6 designed in combination with ergonomics at the top, and is connected to a multi-degree-of-freedom hinge-link mechanism 7 at the end of the gripping device; the resonant cavity is integrated with a temperature sensor, an optical fiber sensor, an infrared sensor transfer interface, a multi-channel microwave signal transmitting device, and a multi-channel microwave reflection signal receiving device, and the foldable and detachable multi-channel microwave transceiver antenna 5 can be opened and closed by pulling the cable sleeve 13 at the center axis of the multi-channel microwave transceiver antenna 5. The flexible high-temperature resistant sponge 11, the flexible sealing ring 10, and the flexible metal film 2 are all made of flexible high-temperature resistant materials, which facilitates the resonant cavity to be closely attached to the surface 1 of the damaged fiber-reinforced resin-based composite component with a curved surface. And on the outside of the flexible metal film 2, an adjustable locking collar 3 is installed to achieve locking and fixing of the fitting part. A gripping device 6 with ergonomic design is connected to the top of the resonant cavity, and a multi-degree-of-freedom hinge-link mechanism 7 with self-locking function is connected to the end of the gripping device. After the resonant cavity is fixed to the area to be repaired, only a self-locking nut 8 needs to be tightened to fix the multi-degree-of-freedom linkage mechanism. After the repair work is completed, the gripping device, the multi-degree-of-freedom hinge-link mechanism 7, the multi-channel microwave transceiver antenna 5, and the adjustable resonant cavity can be completely disassembled and folded and stored in the field microwave rapid repair instrument.

[0009] The external field microwave repair instrument 9 is mainly used for repairing the surface of fiber-reinforced resin-based composite material components with variable curved surfaces. A flexible high-temperature resistant sponge 11 and a flexible sealing ring 10 are installed at the bottom of the resonant cavity, and a layer of flexible metal film 2 is wrapped on the outside of the resonant cavity, and is locked and fixed with an adjustable locking collar 3, so as to ensure that the resonant cavity can adapt to the repair of different curved surfaces. When the curvature of the surface of the area to be repaired is large, the resonant cavity can be replaced with a resonant cavity shell suitable for special working surfaces to adapt to the repair of special working surfaces.

[0010] The detachable multi-channel microwave transceiver antenna 5 can be opened by pulling the cable sleeve 13 when repairing the damaged surface 1 of the fiber-reinforced resin-based composite material component. At the same time, the multi-channel microwave transceiver antenna 5 also integrates an infrared sensor, a temperature sensor, a microwave reflection signal receiving sensor and a multi-channel microwave source transmitter, and is connected to the host of the external microwave repair instrument 9 through a coaxial cable bus. After the repair work is completed, the multi-channel microwave transceiver antenna 5 is closed by pulling the cable sleeve 13, and folded and stored in the external microwave repair instrument 9.

When repairing damaged components of fiber-reinforced resin-based composite materials, the resonant cavity is fixed and pressed to achieve close adhesion between it and the surface of the composite component. The resonant cavity can be fixed by only tightening the self-locking nut 8. In addition, the end of the multi-degree-of-freedom hinge-link mechanism 7 is fixedly installed between the link mechanism and the external field microwave repair instrument 9 through the magnetic locking device 16. After the repair work is completed, when disassembling the equipment, only the magnetic locking knob 15 and the self-locking nut 8 need to be rotated to complete the disassembly of the resonant cavity and the connecting rod mechanism.

[0012] The second technical solution of the present invention is:

[0013] A method for using an external microwave rapid repair device, characterized in that it comprises the following steps:

[0014] Step 1: Connect the magnetic locking device 16 to the end of the multi-degree-of-freedom hinge-link mechanism 7 that realizes the self-locking function, and fix the magnetic locking device 16 on the external field microwave repair instrument 9, and rotate the magnetic locking knob 15 to complete the installation and fixation between the microwave repair instrument and the hinge-link mechanism; install the end of the holding device 6 designed in combination with ergonomics to the top of the multi-degree-of-freedom hinge-link mechanism 7, and tighten the self-locking nut 8 at the connection part;

[0015] Step 2: Pull the cable sleeve 13 of the multi-channel microwave transceiver antenna to open the multi-channel microwave transceiver antenna 5, and connect the data bus at the end of the central axis of the multi-channel microwave transceiver antenna 5 to the adapter connector at the top of the central axis of the resonant cavity, tighten the locking nut to fix the multi-channel microwave transceiver antenna 5; then connect the adaptive microwave resonant cavity 14 to the top of the holding device 6, and the installation of the entire equipment can be completed;

[0016] Step 3: Determine the repair position of the fiber reinforced composite component to be repaired, align the resonant cavity with the position to be repaired, fix it through the multi-degree-of-freedom hinge linkage mechanism 7, and pre-press a certain pressure on the resonant cavity so that the flexible sealing ring 10 can be completely attached to the surface 1 of the damaged composite component with variable curvature;

[0017] Step 4: After ensuring that the pre-pressure can make the flexible sealing ring 10 completely adhere to the surface of the damaged fiber-reinforced resin-based composite component with a variable curved surface; tighten the self-locking nut 8 to fix the multi-degree-of-freedom hinge-link mechanism 7; finally, adjust the adjustable locking collar 3 and fix and lock the leak-proof flexible metal film 2 to the cavity wall of the resonant cavity to prevent microwave leakage.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to illustrate certain specific embodiments of the present invention, but are not used to limit the scope of protection of the present invention. In addition, after the present invention is disclosed, any modifications or changes made by those skilled in the art based on the principle of the repair device for damaged fiber composite components in the present invention shall fall within the scope of protection defined in the claims of this application.

[0026] like Figure 1-3 shown.

[0027] An adjustable microwave repair device for damaged components of fiber-reinforced resin-based composite materials includes an adaptive microwave resonant cavity 14, which is installed at the top of a holding device 6 designed in combination with ergonomics. A detachable multi-channel microwave transceiver antenna 5 is connected to the top of the center axis of the cavity of the resonant cavity; the adaptive microwave resonant cavity 14 includes an integrated temperature sensor, an optical fiber sensor, an infrared sensor transfer interface, an adjustable locking collar 3 (threaded structure), a flexible sealing ring 10, a flexible high-temperature resistant sponge 11, a flexible metal film 2, and a detachable multi-channel microwave transceiver antenna 5, such as Figure 1 As shown. A holding device 6 with an ergonomic design is connected to the top of the central axis of the adaptive microwave resonant cavity 14, and a multi-degree-of-freedom hinge-link mechanism 7 with a self-locking function is connected to the end of the holding device 6. A magnetic locking device 16 that can be locked by magnetic force is installed at the end of the hinge-link mechanism. When performing microwave curing repairs on damaged components of fiber-reinforced resin-based composite materials, it is only necessary to fix the position of the resonant cavity and closely adhere it to the curved surface to be repaired, and tighten the self-locking nut 8 to complete the fixation of the multi-degree-of-freedom hinge-link mechanism 7. Moreover, after the repair work is completed, the multi-degree-of-freedom self-locking hinge-link mechanism can be removed from the external field microwave repair instrument 9 by loosening the self-locking nut and rotating the magnetic locking knob. When disassembling and storing the resonant cavity, the multi-channel microwave transceiver antenna 5 can be removed from the resonant cavity body, and the folding and storage of the multi-channel microwave transceiver antenna 5 can be completed by pulling the rope sleeve 13. Finally, the multi-degree-of-freedom hinge linkage mechanism 7 and the holding device can be disassembled from the device, folded and stored in the external field microwave repair instrument 9 to complete the storage of the resonant cavity.

[0028] Details are as follows:

[0029] like Figure 1 As shown, the present invention takes the central axis of the adaptive microwave resonant cavity 14 as the center of the microwave radiator, and installs a multi-channel microwave transceiver antenna 5 (with an opening spring and a folding buckle similar to an automatic umbrella) at the top position of the central axis of the resonant cavity, and the folding and unfolding of the multi-channel microwave transceiver antenna 5 is realized by pulling the cable sleeve 13. The data transmission bus of the multi-channel microwave transceiver antenna 5 is connected to the data transmission bus of the external field microwave rapid repair instrument, and the holding device designed in combination with ergonomics is connected to the top of the adaptive microwave resonant cavity 14. The multi-degree-of-freedom hinge-link mechanism 7 with a self-locking function is connected to the end of the holding device 6, and the magnetic locking knob 15 is rotated to fix the multi-degree-of-freedom hinge-link mechanism 7 on the microwave repair instrument. After installation, adjust the angle and position of the resonant cavity so that the surface of the resonant cavity is closely attached to the surface to be repaired of the damaged fiber-reinforced composite component, and tighten the self-locking nut 8 to fix the hinge-link mechanism. Adjust the adjustable locking collar 3 so that the leak-proof flexible metal film is closely attached to the working surface to be repaired to prevent microwave leakage. After the repair work is completed, the adaptive microwave resonant cavity 14 can be removed from the work surface by rotating the magnetic locking knob 15 and the self-locking nut 8, and the data transmission bus connected to the external field microwave repair instrument 9 can be unplugged to complete the disassembly of the resonant cavity. Loosen the locking nut between the holding device 6 and the multi-degree-of-freedom hinge-link mechanism 7, as well as the locking nut connected to the top of the central axis of the resonant cavity, complete the disassembly of the holding device and the multi-degree-of-freedom hinge-link, and fold and store it in the external field microwave repair instrument 9. Finally, take the foldable multi-channel microwave transceiver antenna 5 out of the adaptive microwave resonant cavity 14, pull the rope sleeve 13 to close the multi-channel microwave transceiver antenna 5, and complete the folding and storage of the multi-channel microwave transceiver antenna 5. Loosen the adjustable locking collar, and store the adaptive microwave resonant cavity 14 and the multi-channel microwave transceiver antenna 5 in the external field microwave repair instrument 9.

[0030] Example.

[0031] An external field microwave repair device for damaged fiber reinforced composite materials, such as Figure 1As shown, the device includes an integrated optical fiber temperature sensor and an infrared sensor for real-time monitoring of temperature changes, an adjustable locking collar 3, a flexible sealing ring 10, a flexible high temperature resistant sponge 11, a flexible metal film 2, an adaptive microwave resonant cavity 14, a multi-channel microwave transceiver antenna 5, and a cable sleeve 13 for controlling the folding and opening of the multi-channel microwave transceiver antenna 5. The surface 1 of the damaged component of the variable curvature composite material of the fiber reinforced resin-based composite material is tightly attached to the flexible sealing ring 10 of the adaptive microwave resonant cavity 14. The flexible sealing ring 10 is lined with a flexible high temperature resistant sponge 11 to improve the fit between the flexible sealing ring 10 and the damaged component surface. The outer rings of the flexible sealing ring 10 and the flexible high temperature resistant sponge 11 are covered with a flexible metal film 2. The flexible metal film 2 should cover the surface of the damaged component at the same time to prevent microwave leakage. Finally, the flexible metal film 2 and the flexible sealing ring 10 are locked on the adaptive microwave resonant cavity 14 with an adjustable locking collar 3. The multi-degree-of-freedom hinge linkage 7 is adjusted, and the adaptive microwave resonant cavity 14 is pressed on the area to be repaired to ensure a close fit between the resonant cavity and the area to be repaired. Tighten the self-locking nut 8 on the multi-degree-of-freedom hinge linkage 7 to fix the position of the resonant cavity. Tighten the adjustable collar on the outside of the flexible metal film to fix the microwave leakage-proof metal film, ensure the close fit between the metal film and the resonant cavity and the bonding surface of the area to be repaired, and prevent microwave leakage.

[0032] like Figure 2 As shown, after the adaptive microwave resonant cavity 14 completes the repair work on the damaged component of the fiber-reinforced composite material, the multi-channel microwave transceiver antenna 5 can be folded and stored by pulling the cable sleeve 13. At the same time, the adaptive microwave resonant cavity 14 can be removed from the external field microwave repair instrument 9 and the surface 1 of the damaged composite component to be repaired by loosening the self-locking nut 8 and the magnetic locking knob 15. By loosening the locking nut connected between the holding device and the multi-channel microwave transceiver antenna 5 and the hinge-link mechanism, the disassembly of the multi-channel microwave transceiver antenna 5, the holding device and the hinge-link mechanism can be completed. Finally, adjust the flexible locking collar, and fold the adaptive microwave resonant cavity 14, the multi-channel microwave transceiver antenna 5, the multi-degree-of-freedom hinge-link mechanism 7 and the holding device 6 into the external field microwave repair instrument 9.

[0033] like Figure 3As shown, if the adaptive microwave resonant cavity works at the lower end of the component to be repaired, the position of the multi-degree-of-freedom hinge-link mechanism 7 can be adjusted to achieve the repair operation of any repair curved surface. And after the staff adjusts the position of the adaptive microwave resonant cavity 14, it only needs to tighten the self-locking nut 8 and lock the flexible adjustable locking collar 3 to complete the installation and fixation of the equipment. In addition, if the curvature of the working surface to be repaired is large, the cavity of the resonant cavity can be replaced to adapt to the repair task of the special curved surface. Therefore, a variety of highly interchangeable resonant cavities suitable for certain special complex curved surfaces are equipped at the top of the multi-degree-of-freedom hinge-link mechanism.

[0034] Figure 1 The method for using the external field microwave rapid repair device shown includes the following steps:

[0035] Step 1: Connect the magnetic locking device 16 to the end of the multi-degree-of-freedom hinge-link mechanism 7 that realizes the self-locking function, and fix the magnetic locking device 16 on the external field microwave repair instrument 9, and rotate the magnetic locking knob 15 to complete the installation and fixation between the microwave repair instrument and the hinge-link mechanism; install the end of the holding device 6 designed in combination with ergonomics to the top of the multi-degree-of-freedom hinge-link mechanism 7, and tighten the self-locking nut 8 at the connection part;

[0036] Step 2: Pull the cable sleeve 13 of the multi-channel microwave transceiver antenna to open the multi-channel microwave transceiver antenna 5, and connect the data bus at the end of the central axis of the multi-channel microwave transceiver antenna 5 to the adapter connector at the top of the central axis of the resonant cavity, tighten the locking nut to fix the multi-channel microwave transceiver antenna 5; then connect the adaptive microwave resonant cavity 14 to the top of the holding device 6, and the installation of the entire equipment can be completed;

[0037] Step 3: Determine the repair position of the fiber reinforced composite component to be repaired, align the resonant cavity with the position to be repaired, fix it through the multi-degree-of-freedom hinge linkage mechanism 7, and pre-press a certain pressure on the resonant cavity so that the flexible sealing ring 10 can be completely attached to the surface 1 of the damaged composite component with variable curvature;

[0038] Step 4: After ensuring that the pre-pressure can make the flexible sealing ring 10 completely adhere to the surface of the damaged fiber-reinforced resin-based composite component with a variable curved surface; tighten the self-locking nut 8 to fix the multi-degree-of-freedom hinge-link mechanism 7; finally, adjust the adjustable locking collar 3 and fix and lock the leak-proof flexible metal film 2 to the cavity wall of the resonant cavity to prevent microwave leakage.

[0039] The present invention does not involve any existing technology that is the same as the existing technology or can be implemented by using the existing technology.
