[0001] This application relates to the technical field of toolboxes, and particularly to a portable high-airtight and constant-humidity archaeological toolbox. Background Art

[0002] Before archaeological excavation, cultural relics form a relatively balanced system with the enclosed burial environment, which slows down or even prevents the corrosion and deterioration of cultural relics, enabling some cultural relics to remain in their original state after thousands of years. However, there are generally problems such as backward supporting facilities and simple living conditions at field or underwater archaeological excavation sites. After being excavated, cultural relics often cannot be well protected and stored, resulting in the rapid oxidation of cultural relics by the oxygen-rich air; the day-night alternation and cold-warm changes in environmental temperature and humidity lead to uneven evaporation of moisture on the surface of cultural relics, causing rapid cracking and deformation; light accelerates the photolysis and photooxidation of cultural relics, prompting discoloration and fading of organic cultural relics and painted cultural relics; various microorganisms, insects, and mildews grow rapidly, severely restricting the progress of cultural relics excavation work.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application.

[0033] In the following detailed description, reference may be made to the accompanying drawings that form a part hereof and that show, by way of illustration, specific embodiments in which the application may be practiced. In the drawings, like reference numerals generally describe substantially similar components in different figures. The various specific embodiments of the application are described in sufficient detail below to enable those of ordinary skill in the relevant art and technology to practice the technical solutions of the application. It should be understood that other embodiments may be utilized or structural, logical, or electrical changes may be made to the embodiments of the application.

[0034] This application aims to solve the problem of environmental changes after archaeological cultural relics are unearthed, and create a low-oxygen environment with stable humidity for the cultural relics. By actively filling nitrogen, the portable high-airtight and constant-humidity archaeological toolbox of this application can keep archaeological cultural relic samples with high airtightness and constant humidity in the special environment at the archaeological excavation site, create a low-oxygen preservation environment for the cultural relics, so as to provide immediate protection for the unearthed cultural relics. In addition to the function of temporary storage during transportation, this archaeological toolbox can also be used as a long-term storage device. When used for a long time, the box body can be connected to a nitrogen generation device, with the function of real-time monitoring and precise regulation of the oxygen concentration in the box, so that the environment in the box is maintained in a stable state. If the conditions for using a nitrogen generation device cannot be met on site, the box body can be connected to a nitrogen cylinder, and nitrogen with different concentrations can be selected according to the on-site situation, and then the equipped ground temperature and humidity sensor can transmit the temperature and humidity data in real time. Although the oxygen concentration cannot be accurately detected, a low-oxygen environment can be maintained. At the same time, the interior of the portable high-airtight and constant-humidity archaeological toolbox of this application adopts a multi-layer structure design. The upper layer is a constant-humidity material and / or an archaeological tool storage area, and the lower layer is a sample storage area. This layered design makes the internal space of the toolbox reasonably utilized, facilitating users to quickly access the required items. Therefore, this application can not only keep archaeological samples with high airtightness and constant humidity, but also has the function of storing excavation tools. Therefore, this application is a small movable equipment integrating tool storage and cultural relic protection.

[0035] Figure 1 is one of the three-dimensional structure diagrams of a portable high-airtight and constant-humidity archaeological toolbox according to an embodiment of this application. Figure 2 is the second three-dimensional structure diagram of a portable high-airtight and constant-humidity archaeological toolbox according to an embodiment of this application. Figure 3An exploded view of a portable high-airtight and constant-humidity archaeological toolbox in an open state according to an embodiment of the present application. Figure 4 It is a schematic three-dimensional structure diagram of the first storage chamber of a portable high-airtight and constant-humidity archaeological toolbox in an open state according to an embodiment of the present application. As Figures 1 to 4 shown, in this embodiment, the portable high-airtight and constant-humidity archaeological toolbox of the present application includes a main body 1. Among them, the main body 1 includes a box body 10 and a box cover 20. The box cover 20 can be flip-fitted onto the box body 1 through a hinge (not shown in the figure). A sealing strip 103 and a sealing strip 203 are provided between the docking edges of the box body 10 and the box cover 20. Two buckles 202 are provided on the box cover 20 to ensure the airtightness of the archaeological toolbox. In addition, a handle 201 is provided on the box cover 20, and the main body 1 is made of acrylic, PE or PP material, so that the archaeological toolbox has the characteristics of being lightweight and portable.

[0036] In this embodiment, an air inlet 101 and an air outlet 102 are respectively opened on the main body 1. Among them, the air inlet 101 is used for an external nitrogen source to fill nitrogen into the interior of the main body 1 to form a low-oxygen environment. The air outlet 102 is used to discharge the gas in the main body 1. In some embodiments, the air inlet 101 is located at the center position on the front surface of the box body 10, and the air outlet 102 is located below the hinge on one side of the back surface of the box body 10.

[0037] Mechanical valves (not shown in the figure) are respectively provided inside the air inlet 101 and the air outlet 102. The mechanical valve inside the air inlet is opened when the nitrogen source is connected and closed when pulled out; the mechanical valve inside the air outlet is opened when the exhaust pipe is connected and closed when pulled out. A mechanical valve is a valve that uses a mechanical structure to achieve automatic locking and opening, and is widely used in occasions where automatic control of gas or liquid flow is required. A mechanical valve usually consists of a valve body, a valve core, a spring, a locking mechanism and a driving component, etc. Its working states include an "open state" and a "closed state".

[0038] 1. Open state: When the valve needs to be opened, the driving component (such as a handle or an electromagnetic coil) is activated, overcoming the spring force, and pushing the valve core to move to the open position. Once the valve core reaches this position, the locking mechanism is automatically activated to lock the valve core in the open state, thus maintaining the flow of the fluid.

[0039] 2. Closed state: When the valve needs to be closed, the driving component is activated again to release the locking of the locking mechanism, and the valve core moves to the closed position under the action of the spring force. At this time, the locking mechanism locks the valve core again to prevent the fluid from flowing.

[0040] In addition, the mechanical valve has a self-locking function. When the valve of the mechanical valve is set at a specific open or closed position, it will remain in this state until it is operated again by an external driving component. This design can prevent the accidental change of the valve position due to system pressure changes or other interference factors. The mechanical valve is simple and reliable in design and is suitable for a variety of industrial and civil applications. Especially in systems that require frequent operation or remote control, the mechanical valve can provide stable operating performance and safety protection.

[0041] Generally, a plug-and-play mechanical valve is adopted, and its internal valve disc opens when inserted and closes when pulled out. In this embodiment, for example, a commercially available SMC type one-way valve quick connector can be used as the mechanical valve. The female head model is KK2S-06E, and the male head model is KK2P-06H, but it is not limited to this in actual applications. Among them, the female head is connected to the box body 10, and the male head is connected to the exhaust pipe. The female head is usually in a self-locking state, that is, a closed state. When in use, the male head is inserted into the female head, and the mechanical lock is opened to achieve ventilation. In view of this, the internal structure and working principle of the mechanical valve will not be elaborated here.

[0042] When using the portable high-airtight and constant-humidity archaeological toolbox of the present application for gas replacement, an external quick connector is required. When the quick connector is connected to the air valve, the valve airway can be mechanically opened to achieve gas exchange.

[0043] Specifically, during the gas replacement stage, that is, when exhausting gas, the valves of the inflation port 101 and the air outlet 102 need to be opened simultaneously. Install the exhaust pipe on the air outlet 102. The mechanical valve inside the air outlet 102 is opened, and the mechanical valve inside the inflation port 101 is opened, so that both the inflation port 101 and the air outlet 102 are in an open state. Actively inflate nitrogen into the inflation port 101 through a nitrogen source to replace the gas inside the main body 1 and discharge the gas. When inflating, first, it is necessary to remove the quick connector and the exhaust pipe of the air outlet 102, and the mechanical valve inside the air outlet 102 is closed to close the air outlet 102. Then, connect the inflation port 101 to the nitrogen source externally. The nitrogen source ejects the gas inside it, and the mechanical valve inside the inflation port 101 is opened. Nitrogen enters the main body 1 unidirectionally from the inflation port 101, and the mechanical valve inside the air outlet 102 is closed to fill nitrogen into the main body 1; when the nitrogen source is pulled out, the mechanical valve inside the inflation port 101 is closed to prevent gas from flowing in. The nitrogen source can be a nitrogen generator or a nitrogen cylinder. In this embodiment, the nitrogen generator has both filling and pumping functions. On the one hand, the nitrogen generator can fill the generated nitrogen into the main body 1. On the other hand, the nitrogen generator can also extract gas from the main body 1 for monitoring the gas concentration. The nitrogen cylinder can be selected with different concentrations for inflation. Although the oxygen concentration cannot be accurately detected, a low-oxygen environment can be maintained in a relatively harsher archaeological environment.

[0044] Furthermore, the main operation steps when using a nitrogen generator as the nitrogen source include:

[0045] Step S1, detect the temperature and humidity of the archaeological toolbox. Monitor the current temperature or humidity change inside the archaeological toolbox through the temperature and humidity detection device in the main body 1. The nitrogen generator has functions of displaying temperature, humidity, and oxygen content, and the humidity and oxygen content are automatically adjusted according to the settings. When the humidity exceeds or the oxygen content exceeds / falls below the set threshold, for example, the set value of the oxygen content in the main body 1 is 5%, with an error of ±1%, and the relative humidity is 50%RH, with an error of ±5%. When the oxygen content detection value is 4% and the relative humidity is 47%RH, which meets the requirements, the nitrogen generator automatically stops. If the oxygen content detection value is 4% and the relative humidity is 57%RH, and any one of the indicators exceeds the set value, the nitrogen generator will automatically adjust until all meet the set value and the error range.

[0046] Step S2, detect whether the nitrogen concentration inside the current archaeological toolbox meets the requirements through the nitrogen generator. The user needs to connect the nitrogen generator and connect the nitrogen generator to the inflation port 101 of the main body 1. The nitrogen generator extracts nitrogen from the main body 1 and monitors the nitrogen concentration to judge whether the nitrogen concentration inside the current archaeological toolbox meets the requirements.

[0047] Step S3, if the nitrogen concentration in the current archaeological toolbox is lower than the set threshold, nitrogen is filled into the archaeological toolbox through a nitrogen generator.

[0048] Step S4, monitor the nitrogen concentration. While the nitrogen generator fills nitrogen into the main body 1, it also extracts nitrogen from the main body 1 to judge the nitrogen concentration in the current environment. For example, when the monitored nitrogen concentration reaches the threshold of 95% of the nitrogen concentration, the nitrogen generator will automatically stop inflating.

[0049] In some embodiments, in addition to using a nitrogen generator, the nitrogen source can also directly use a nitrogen cylinder. At this time, the steps of inflating the archaeological toolbox mainly include:

[0050] First, the nitrogen cylinder needs to be adjusted to an appropriate flow rate; second, the air duct needs to be connected to the inflation port end, and the exhaust port is externally connected to the exhaust pipe for gas replacement inside the box. During the replacement, the box cover needs to be closed, and the replacement time is about 5 minutes. After the replacement stage is over, the exhaust pipe externally connected to the exhaust port is removed, and the box is inflated with a slightly smaller gas flow rate than that in the replacement stage. The inflation stage can last for 3 minutes. After inflation, the gas valve of the nitrogen cylinder needs to be closed first, and then the air duct of the inflation port is removed.

[0051] In some embodiments, the archaeological toolbox of the present application is also equipped with a low-oxygen module to reduce the oxygen content in the main body. For the convenience of placement and space saving, the low-oxygen module can adopt a sheet-shaped consumable. Since the low-oxygen module will generate a certain amount of heat during the deoxygenation reaction, it can usually be placed at the tray 30 in the first storage room. That is to say, in the case where the working environment is harsh and nitrogen cannot be actively filled into the toolbox, the low-oxygen module can be directly placed in the archaeological toolbox, which can also effectively reduce the oxygen content in the main body, that is, the oxygen content in the first storage room and the second storage room.

[0052] In addition to the function of temporary storage during transportation, the archaeological toolbox of the present application can also be used as a long-term storage device. When used for a long time, the archaeological toolbox of the present application can be connected to a nitrogen generator to realize the functions of real-time monitoring and precise regulation of the oxygen concentration in the box, so as to keep the environment in the box in a stable state.

[0053] As Figure 3 shown, in this embodiment, the portable high-airtight and constant-humidity archaeological toolbox of the present application further includes a tray 30 and a sample rack 40. Among them, the tray 30 is detachably arranged at the top inside the main body 1, and is used for storing constant-humidity materials and / or archaeological tools; the sample rack 40 is detachably arranged at the bottom inside the main body 1, and is used for storing archaeological samples.

[0054] Combined Figure 4 It can be seen that in this embodiment, a limiting boss 104 is provided on the inner wall of the box body 10 near the opening to carry the tray 30; wherein, the tray 30 divides the space inside the body 1 into a first storage chamber located above and a second storage chamber located below (as Figure 8 shown), that is: the box cover 20, the tray 30 and the inner wall of the box body 10 together form the first storage chamber. A temperature and humidity detection device is placed on the tray 30 in the first storage chamber to detect the humidity retention of the first storage chamber. The temperature and humidity detection device sends real-time monitoring signals to an external terminal monitoring device for data recording or to determine further operation and processing work.

In some embodiments, the temperature and humidity detection device can be a monitoring card, which can be placed in the first storage chamber, that is, in the upper tray 30, for easy viewing and operation by the user. In other embodiments, the archaeological toolbox can be used in combination with passive humidity control consumables to provide a stable constant-humidity environment for cultural relics in a power-off environment. Among them, the humidity control consumables are sheet-shaped consumables friendly to cultural relics, and can be placed at any position in the archaeological toolbox.

In this embodiment, a bridge-type handle 301 facilitating taking and placing is provided on the tray 30, and the area below the bridge-type handle 301 is hollowed out. This hollowed-out setting helps reduce the weight, making it convenient for handling and providing an air replacement channel for the upper and lower spaces to maintain good ventilation. A plurality of partition plates are provided on the tray 30 to divide it into a plurality of grid areas. In some embodiments, the partition plates include a partition plate 302 integrated with the bridge-type handle 301 and an independent partition plate 303, which are used to store the humidity control material and / or the archaeological tools respectively. The design of the partition plate 302 and the partition plate 303 on the tray 30 enables the humidity control material and the archaeological tools to be stored separately, avoiding cross-contamination.

In some other embodiments, ventilation holes are provided directly below the bridge-type handle 301 of the tray 30, and the ventilation holes communicate the first storage chamber and the second storage chamber with each other. A temperature and humidity detection device is placed on the tray 30 in the first storage chamber, which can be used to detect the temperature and humidity of the first storage chamber and the second storage chamber.

[0061] Among them, the sample rack 40 is made of foam material, and the use of this material provides soft support for archaeological samples to prevent damage during transportation.
