[0031] In an exemplary embodiment, the upper surface of the case 1 is provided with a slow back hand 17 and a telescopic shoulder strap 18. The slow back hand 17 and the telescopic shoulder strap 18 can facilitate the user to put and take the case 1, so that the case 1 is more convenient to move to the position of the patch 24 needing curing and repair.

[0032] In an exemplary embodiment, the rear surface of the case 1 is provided with a telescopic pull rod 19, and the bottom of the case 1 is provided with at least one pulley 20. The telescopic pull rod 19 cooperates with the pulley 20, so that when moving on a relatively flat ground / surface, the telescopic pull rod 19 can be used as a push rod, and the case 1 can be pushed to move on the ground / surface, which is more convenient to operate.

[0033] In an exemplary embodiment, the outer side of the case 1 is provided with a cooling fan 21, the case is provided with a cooling channel corresponding to the mounting position of the cooling fan 21, and the cooling fan 21 is electrically connected with the charging power supply 10. The cooling fan 21 is directly powered by the charging power supply 10. During the process of monitoring the repair and curing of the patch 24, the cooling fan 21 is started to cool the components inside the case 1, such as the thermal repair instrument 5, the air source electric pump 6, the dielectric instrument main machine 7, the dielectric box 8, the display control unit 9, the charging power supply 10, etc., to avoid short circuit or other failures caused by overheating of the above components, and to ensure the service life of the components.

[0034] In an exemplary embodiment, as shown in Figure 1 , the display control unit 9 comprises a touch display 901 and a computer main machine 902; wherein the computer main machine 902 is signal connected with the touch display 901, the touch display 901 is arranged on the outer side of the case 1, and the computer main machine 902 is fixed on the upper end of the third sliding drawer assembly 4.

[0035] In an exemplary embodiment, the first sliding drawer assembly 2, the second sliding drawer assembly 3 and the third sliding drawer assembly 4 have the same structural composition. Taking the first sliding drawer assembly 2 as an example, as shown in Figure 1 , the first sliding drawer assembly 2 comprises a first sliding drawer plate 201 and a first pull rod 202, the two ends of the first sliding drawer plate 201 are movably installed inside the case 1 through the sliding rail 101 arranged inside the case 1, and the first pull rod 202 is fixedly connected with the end of the first sliding drawer plate 201.

Wherein, the first sliding drawer plate 201 is not necessarily square as shown in Figure 1 , but can also be L-shaped as shown in Figure 3 . When the first sliding drawer assembly 2, the second sliding drawer assembly 3 and the third sliding drawer assembly 4 all have L-shaped sliding drawer plates, the opening side of the case 1 for mounting each sliding drawer assembly is closed. At the same time, considering that the case 1 is moved, in order to avoid the sliding drawer assemblies from sliding out of the case 1 due to external impact, a lock piece can be installed in cooperation with the inner side wall of the case 1 and the sliding drawer plate. The specific structure of the lock piece can refer to the installation of a drawer lock. Only when the corresponding sliding drawer assembly needs to be opened, the lock piece will be opened.

[0037] In an exemplary embodiment, the charging power supply 9 is a lithium battery, and the outer side of the case 1 is provided with a charging port 22 corresponding to the charging power supply.

[0038] The following embodiment of the utility model will be further illustrated by a specific maintenance case to show the feasibility and progressiveness of the utility model. It should be noted that in the following maintenance case, the model and size of most components in the portable device for composite material field maintenance and curing monitoring will be specifically exemplified. It can be understood that such exemplification is only an example and is not a limitation of the utility model. The utility model does not necessarily limit each component according to the model as exemplified below.

[0039] The composite material thermal repair instrument and the air source electric pump are installed at the bottom of the portable device and are fixed on the first sliding assembly 2. The thermal repair instrument is model HCS9000B and the air source electric pump is model HCS20055-04, both of which are manufactured by HEATCON Company. The main size of the thermal repair instrument is about 46cm*34cm*15cm and the main size of the air source electric pump is about 48cm*15cm*10cm. The air source electric pump integrates a vacuum gauge, a fuse and a motor. The thermal repair instrument provides temperature conditions for the curing of the repair patch 24 and the air source electric pump provides negative pressure conditions for the curing of the repair patch 24. There is an air source electric pump starting switch on the left side of the case.

[0040] The dielectric instrument host 7 is selected as a dielectric method resin curing monitor (DEA instrument) and is located in the middle layer of the case 1 together with the dielectric box 8 and is fixed on the second sliding assembly 3. The DEA instrument is model DEA 288 and is manufactured by Germany Nide Company. The size of the DEA instrument host is about 50cm*36cm*20cm and the main size of the dielectric box which must be connected is about 20cm*8cm*6cm. The DEA instrument is connected with the dielectric box 8 through a cable and the dielectric box 8 is connected with a dielectric sensor to monitor the change of ion viscosity of the repair patch 24 in the curing process.

[0041] The display and control unit 9 is located at the uppermost layer of the case 1 and is a designed integrated computer including a touch display screen 901 and a computer host 902. The touch display screen 901 is placed on the outside of the portable device and can be touched and operated. The computer host 902 is buried in the interior of the portable device and is fixed on the third sliding assembly 4. The size of the control and display computer is about 50cm*46cm*15cm. The computer host 902 can control the thermal repair instrument and the DEA instrument through control software and does not need to separately operate the running program of the thermal repair instrument and the DEA instrument, thereby playing a portable role. At the same time, the designed computer host 902 can display the reading of the vacuum gauge of the air source electric pump.

[0042] Lithium battery is fixed at the back of the portable device, close to the telescopic pull rod. The size of lithium battery is 55cm x 46cm x 21cm, and each electrical equipment inside the case is connected with lithium battery. When the device is running, lithium battery can provide energy for each equipment, and each equipment does not need to be externally connected with a separate wire. At the same time, the back side of the portable device (outside the telescopic pull rod) is provided with a lithium battery charging port to ensure the power supply of the device and play a portable role.

[0043] Three wire winding columns are arranged on the right side of the portable device, and from bottom to top, the first wire 14 leading out the electric blanket, the second wire 16 leading out the dielectric sensor / thermocouple, and the vacuum valve connecting pipe 15 can be wound, respectively. The side close to the portable device of the wire winding column is provided with a hole, which is convenient for leading out the electric blanket, dielectric sensor / thermocouple and vacuum valve from the inside of the device, dielectric box and air source electric pump, and storing through the wire winding column, playing a portable role.

[0044] The slow back handle and the telescopic back strap are located on the upper surface of the portable device case 1 shell, the telescopic pull rod is located on the back surface of the portable device, and the pulley is located at the bottom of the portable device. During the carrying process before use, the worker can carry the device by the slow back handle, or push / pull the device by the telescopic pull rod and pulley, or move the device by the telescopic back strap, playing a portable role.

[0045] The dielectric sensor is used to monitor the change of ion viscosity in the curing process of the composite material, and the suitable sensor model includes: IDEX 115 / 35T with / without filter cloth version (temperature monitoring is available), IDEX 115L (temperature monitoring is not available) and mini IDEX (temperature monitoring is available), and the type of the sensor is determined according to the type of the monitored composite material. For example, for the curing monitoring of the carbon fiber reinforced plastic (CFRP) patch 24 in this paper, the sensor with filter cloth version is required to prevent the dielectric metal sensor from contacting and conducting with the carbon fiber, and the IDEX 115L sensor with filter cloth version is selected (this sensor has no temperature monitoring function, and a K-type thermocouple needs to be separately connected between the dielectric box and the CFRP patch 24).

[0046] The first slide assembly 2, the second slide assembly 3 and the third slide assembly 4 are located inside the case and carry the hot repair instrument / air source electric pump, the dielectric instrument / dielectric box and the control and display computer from bottom to top, respectively. The pull rod is located outside the slide rail to facilitate pulling out the slide rail. During the maintenance of the device, the equipment can be taken out / put in through the slide rail, playing a portable role.

[0047] The cooling fan is located outside the left side shell of the case and is used for ventilation and heat dissipation inside the case. The cooling fan is directly powered by the lithium battery, and starts to operate at the same time when the lithium battery switch is turned on.

[0048] Selection of control software: Installation of the following software on the computer host 902 in the display control unit 9: curing parameter data acquisition and analysis software, dielectric real-time monitoring software NETZSCH DEA Measurement, and dielectric analysis software Analysis. The curing parameter data acquisition and analysis software can set the curing process required for the patch 24, directly call the data in the process library from the software, manually input if there is no curing parameter of the target patch 24 in the process library, and then click the "Start Program" button to realize the curing of the patch 24. The dielectric real-time monitoring software can obtain the information of the ion viscosity of the patch 24 during the curing process, and can directly start the dielectric analysis software through the software to realize real-time analysis of the curing state of the patch 24. The control architecture is shown in Figure 5 . The control software can control the curing and monitoring of the patch 24 at the same time, which is more portable than the original host control of each device separately.

[0049] As shown in Figure 4 , when the patch 24 is repaired by using the portable device, the dielectric sensor (model: filter cloth IDEX 115L) is placed in the sealed bag, the monitoring electrode side is in contact with the matrix resin of the composite patch 24, and the electric blanket is placed in the sealed bag. The vacuum valve connecting pipe is connected with the vacuum valve placed in the sealed bag, and then the sealed bag is packaged. The curing process required for the patch 24 (heating / cooling rate, holding time) and the ion viscosity monitoring parameters (dielectric frequency, material information, sensor information, etc.) are set through the display control unit 9. Taking the T300 / 2019B medium temperature curing epoxy resin composite patch 24 as an example, combined with Figure 6 , the use method of the portable device includes the following steps:

[0050] Step 1, package the patch 24, during which the sensor, electric blanket and vacuum valve are buried in the vacuum bag 23, as shown in Figure 4 . Turn on the lithium battery switch and start the device.

[0051] Step 2, input the curing process parameters: heating to 125℃-heating rate 1℃ / min; holding at 125℃ for 120min; cooling from 125℃ to 40℃-cooling rate 1℃ / min. Set the dielectric monitoring parameters: monitoring frequency, monitoring time, etc.

[0052] Step 3, turn on the air source electric pump switch, extract the air in the sealed bag, and display the vacuum degree on the computer. If the vacuum degree does not reach-75Kpa, the sealing degree of the sealed bag needs to be checked manually until the sealing degree meets the requirements; then the total control software runs the program to monitor the ion viscosity of the patch 24 during the curing process.

[0053] Step 4, the curing process acquires the ion viscosity information of the patch 24 in real time, the complete ion viscosity curve is obtained after the curing is completed, and the curing index is analyzed by using software, as shown in Figure 7 .

[0054] The above embodiments are only used for describing the present application, but not for limiting the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions belong to the scope of the present application, and the patent protection scope of the present application should be defined by the claims.
