[0041] Referring to Figure 3 , the surface of the rubber ring block 302 is provided with an embedding groove 304, and the inner wall of the ring groove 303 is provided with a sliding contact assembly 305, wherein when the tank door 102 is pressed and sealed with the tank body 101, the contact column head 305a is embedded into the inside of the embedding groove 304.

The contact column head 305a and the embedded slide column 305b are installed in the inner part of the slot hole 106 and are designed as an integrated structure.

[0043] With reference to Figure 6 The inner part of the inner groove 305d is provided with an ultrasonic sensor 306. The monitoring end of the ultrasonic sensor 306 faces the embedded groove 304 and is used for scanning and monitoring the internal cracks of the rubber ring block 302. The ultrasonic sensor 306 is electrically connected to the processor. The end part of the inner groove 305d is provided with a panel 307.

[0044] With reference to Figure 6 The integrated contact column head 305a and the embedded slide column 305b are further provided with a large-diameter expansion ring 305c at the middle position thereof. The matching installation area of the expansion ring 305c is located in the inner part of the expansion groove 106b. A spring 308 is further installed between the expansion ring 305c and the expansion groove 106b. The spring 308 is used for limiting the entire slide contact assembly 305. After the tank door 102 is opened, the slide contact assembly 305 is ejected from the slot hole 106, that is, the slide contact assembly 305 is located at the initial position.

[0045] With reference to Figure 6 The end part of the embedded slide column 305b and the inner wall of the slot hole 106 are provided with a leaf spring 309. The inner part of the leaf spring 309 is integrated with a pressure sensor for monitoring the pressure of the contact and extrusion of the slide contact assembly 305. The pressure sensor is electrically connected to the processor.

[0046] With reference to Figure 1 , Figure 2 The monitoring component 300 is provided with ten groups. The positions of the ten groups of monitoring components 300 correspond to and match the positions of the ten groups of locking components 200.

[0047] Further, the processor comprises a rubber strip monitoring module, a pressure monitoring module and a data processing module.

[0048] With reference to Figure 6 Further, the rubber strip monitoring module acquires the data fed back by the ultrasonic sensor 306, is used for monitoring the internal aging state of the rubber ring block 302, monitors the crack state existing in the inner part of the rubber ring block 302, and transmits the monitored data signal to the data processing module.

[0049] Specifically, after the tank door 102 is closed with the tank body 101, the contact column head part 305a is located inside the embedding groove 304, that is, the inside of the rubber strip ring block 302. By the operation of the ultrasonic sensor 306, the aging state of the inside of the rubber strip ring block 302 is monitored, the crack state inside the rubber strip ring block 302 is identified, the data obtained by monitoring is fed back to the rubber strip monitoring module, the rubber strip monitoring module analyzes the crack data obtained by monitoring to generate a coefficient, which is marked as a gap monitoring coefficient T, and the rubber strip monitoring module transmits the gap monitoring coefficient T to the data processing module.

[0050] Referring to Figure 6 Further, the pressure monitoring module is used to obtain the contact pressure generated between the internal sliding contact assembly 305 and the embedding groove 304 when the tank door 102 is closed by the locking part 200, and transmit the monitored data signal to the data processing module. The embedded sliding column part 305b of the sliding contact assembly 305 is continuously compressed after the tank door 102 is closed, and the rotating disc 204b continuously rotates to lock, which will cause the sliding contact assembly 305 to be continuously compressed. The pressure sensor transmits the monitored data to the pressure monitoring module. During the operation of the pressure monitoring module, it is a continuous monitoring process.

[0051] Since the tank door 102 is closed and sealed with the tank body 101, the monitoring data area of the pressure sensor is stable at this time. The tank door 102 has a threshold value in a completely sealed state. When the pressure sensor reaches or exceeds this threshold value, it represents that the tank door 102 in this state is in a completely sealed state. The data processing module compares the real-time monitoring value of the pressure sensor with the threshold value. If the threshold value is not reached, the indicator light 301 is turned on. If the threshold value is reached, the indicator light 301 is turned off. Therefore, when the tank door 102 is sealed, the rotating disc 204b is rotated until each indicator light 301 is turned off.

[0052] Specifically, since the aircraft hot press tank creates various environments such as different pressure environments, different temperature environments, and different humidity environments inside the tank body 101 when processing the internal materials, the growth and manufacturing of the aircraft materials are catalyzed in this high-temperature and high-pressure environment. Since the tank door 102 is closed, the sealing property of the tank door 102 and the tank body 101 will change due to the high-temperature and high-pressure environment inside the tank body 101. Different positions may produce a non-sealed state. At this time, the real-time monitoring data of the pressure sensor will fluctuate. The pressure sensor transmits the monitoring data to the pressure monitoring module. The pressure monitoring module analyzes the data monitored by the pressure sensor to generate a data, which is marked as a pressure monitoring coefficient F. The pressure monitoring module transmits the pressure monitoring coefficient F to the data processing module.

[0053] Further, the data processing module: the monitoring data signal of the ultrasonic sensor 306 is transmitted to the data processing module by the adhesive tape monitoring module, the monitoring data of the pressure sensor is transmitted by the pressure monitoring module, and the data processing module performs weighted operation analysis according to the obtained adhesive tape monitoring data and pressure monitoring data to comprehensively judge whether the sealing of the current position needs to be adjusted.

[0054] In order to solve the problem of the sealing of the tank door 102 under the condition of high temperature and high pressure in the tank body 101, specifically, the data processing module analyzes the gap monitoring coefficient T transmitted by the adhesive tape monitoring module and the pressure monitoring coefficient F transmitted by the pressure monitoring module, combines the two coefficients by weighting, and respectively introduces corresponding weight coefficients and , which represent their importance in the weighting process. The weighted sum expression is:

[0055] = × + × ;

[0056] Among them:

[0057] : is the gap monitoring coefficient of the ultrasonic sensor to the gap inside the adhesive tape ring block

[0058] : is the pressure monitoring coefficient generated by the pressure sensor sliding contact assembly

[0059] : is the weight of the gap monitoring coefficient

[0060] : is the weight of the pressure monitoring coefficient

[0061] Further, the processor further includes a data feedback module, and the data feedback module includes an indicator light 301 fixed on one side of the tank door 102. The data feedback module controls the on-off of the indicator light 301 according to the analysis and processing result of the data processing module.

[0062] Specifically, S obtained by the data processing module calculation and analysis is equivalent to whether the corresponding locking component 200 rotating disc 204b needs to be screwed and fastened, that is, whether the sealing of ten groups of monitoring components 300 monitoring positions is good and whether air leakage occurs. A threshold value G can be set to judge the on-off of the indicator light 301.

[0063] Among them: G is a preset threshold value, which is set according to the actual situation, indicating that when the comprehensive result S exceeds the threshold value T, it means that the indicator light 301 needs to be turned on to remind the user to fasten the rotating disc 204b at the corresponding position, otherwise it is not necessary.

[0064] Turning on the indicator light 301

[0065] In practical applications, the weights and should be based on the specific application scenarios and requirements to ensure that they can accurately reflect the relative importance in the scene. At the same time, the sum of the two weights should usually be equal to 1 (or 100%, if expressed in percentage form), to represent that they together constitute the entire weight of the weighted sum.

[0066] In the working process, the above-mentioned adhesive strip monitoring module, pressure monitoring module and data processing module are a continuous working process, which is a process of real-time collection of internal data. The adhesive strip monitoring module transmits the gap monitoring coefficient T to the data processing module, the pressure monitoring module transmits the pressure monitoring coefficient F to the data processing module, and the data processing module substitutes the relevant data into: = × + × The data processing module compares the size of S and the threshold value G, and the data feedback module makes the bright and dark action signal of the indicator light 301. When S G, the indicator light 301 corresponding to the position is turned on, prompting the operator to tighten the corresponding position of the rotating disc 204b to maintain sealing; when S G, the indicator light 301 is turned off, prompting the operator to take no action.

[0067] In the working process of the aviation hot press tank, due to the high heat and high pressure inside the tank body 101, the phenomenon of insufficient sealing of the tank door 102, through the process of real-time monitoring and the bright and dark action of the indicator light 301, the operator can be assisted to perform emergency sealing, which can also better guarantee the growth and manufacturing environment of the internal aviation materials, and improve the manufacturing success rate of the aviation materials.

[0068] The above formulas are all dimensionless numerical calculations, and the formulas are obtained by software simulation of a large amount of data to obtain a formula of the nearest real situation, and the preset parameters in the formula are set by the person skilled in the art according to the actual situation.
