Description

Technical Field

[0001] The utility model relates to the technical field of cultural relic preservation chambers, in particular to a cultural relic preservation chamber capable of digitally removing oxygen and changing constant humidity values. Background Art

[0002] In the excavation, preservation and restoration of cultural relics, preventing cultural relics from being damaged by oxidation and maintaining a stable humidity are always two fundamental issues; once cultural relics that have been buried underground for thousands of years are unearthed, the instantaneous destruction of the original preservation environment will greatly challenge the tolerance limit of the cultural relics themselves. For fragile paper or silk fabrics, this challenge is usually a disaster, and the bright colors and flexible textures quickly turn black and brittle. This oxidation damage to cultural relics is called "carbonization" in the industry; changes in humidity cause the structural fibers of cultural relics to twist and deform until they dry and break. Therefore, controlling constant humidity and deoxygenation protection have always been an important part of cultural relic work.

[0003] Compared with the needs of cultural heritage protection, the available technical means are relatively insufficient. In recent years, large-scale humidity control equipment has begun to appear in the warehouse construction of some cultural and museum units, and heavy-duty deoxygenation equipment has been installed in a very small number of places. This can promote the protection of cultural relics to a certain extent. However, since it is a facility fixed in the warehouse and does not have the convenience of mobility, it cannot meet the needs of mobile protection of cultural relics from excavation to restoration and even scientific research exchanges. Therefore, we have specially developed this lightweight and portable cultural relic protection cabin. Utility Model Content

[0010] As a preferred embodiment of the present invention, an elastic sealing ring is further disposed between the top closing frame and the main frame.

[0012] As a preferred embodiment of the utility model, an electronic monitoring module, a guide tube and a gas injection pipe are arranged in the installation groove, and a one-way gas valve is also arranged in the main frame. A gas injection port, an oxygen detection port, a charging port, a medicine liquid replenishing port and an exhaust port are arranged in sequence on one side of the main frame close to the installation groove.

[0013] As a preferred embodiment of the utility model, the charging port is electrically connected to the electronic monitoring module, and one end of the gas injection pipe is arranged on the gas injection port; the other end of the gas injection pipe is arranged in the installation groove, and the gas outlet of the gas injection pipe is upward and located in the upper part of the installation groove space; the gas outlet valve port of the one-way air valve is connected to the exhaust port, and the air inlet valve port of the one-way air valve is provided with an exhaust pipeline, and the end of the exhaust pipeline away from the one-way air valve is arranged in the humidity control medicine cabin, and is located at the bottom of the humidity control medicine cabin; one end of the guide tube is connected to the medicine liquid replenishing port, and the other end of the guide tube is connected to the medicine liquid absorption layer.

[0014] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0015] 1. The utility model has a digital oxygen monitoring function, which can realize the oxygen-free state. The real-time digital delayed detection device makes the gas replacement work accurate and efficient. The sequential combined operation of nitrogen and helium makes the common replacement error smaller. The long-term continuous helium injection of external equipment effectively avoids the agitation of the gas in the cabin and forms a pure gas stratification. The design of the exhaust pipeline ensures that the air to be discharged is deposited at the bottom of the cabin, and finally enters the exhaust pipeline from the lowest point and is discharged outside the cabin. The oxygen-free state is particularly important for the protection of cultural relics. This protection cabin can provide an ideal means for cultural relics protection work.

[0016] 2. The utility model has the function of resetting the constant humidity target value. Through the liquid medicine replenishment port and the pipeline in the cabin, the user can readjust the liquid medicine ratio in the cabin according to his own needs. The newly injected liquid medicine is mixed with the original liquid medicine in the absorption layer, changing the original ratio and thus changing to a new constant humidity target value. The entire operation process does not require moving or opening the protection cabin, eliminating the risk of accidental damage to the cultural relics. When the process is completed and the injection needle is pulled out of the liquid medicine replenishment port, the sealing plug in the port rebounds again to complete the sealing, and does not affect the overall airtight state of the protection cabin.

[0017] 3. The utility model has the functions of electronic monitoring, wireless data transmission and satellite positioning. The main power supply, satellite locator, signal transmitter, oxygen content detector and temperature and humidity sensor are centrally installed in the equipment integration cabin. Through the multiple breathable square holes of the supporting partition and the breathable component structure in the cabin, the bottom and upper gases in the protective cabin are monitored in real time and the data are wirelessly uploaded to the user; the data includes oxygen content, temperature, humidity, time, over-limit alarm, satellite positioning, historical movement trajectory, etc. The user can also change the detection settings remotely.

[0018] 4. The utility model has a docking terminal that can be matched with an external machine, and can realize long-term digital automatic operation without manual work, so as to meet the protection work of deoxygenation and reoxygenation of cultural relics; the gas injection port adopts a standard type of airtight docking valve to dock with the external nitrogen and helium machine, and injects protective gas for a long time under the set air pressure and flow rate; the exhaust port also adopts a standard model interface to connect with the external gas recovery tank, and collects the exhaust gas in the exhaust pipe for users to monitor and analyze data. After all values ​​meet expectations and remain stable for a period of time, the gas injection machine stops working, the gas injection port and the exhaust port valves are automatically closed, and the gas replacement process ends. This process does not require manual operation, avoids deficiencies caused by improper human operation, and ensures that the protective cabin can reach an oxygen-free state; vice versa, there will be a need to take and put cultural relics many times during the research process of cultural relics. This digital operation can avoid the re-violent oxidation of cultural relics caused by the rapid breaking of the oxygen-free environment, and can allow cultural relics to gradually adapt to the long-term slow oxygen injection, avoiding carbonization damage caused by the rapid entry of oxygen.

[0019] 5. The main body of the utility model is made of airtight waterproof material, and the inner wall is sealed by polymer melt-plastic processing to maintain good airtight performance. Under the effect of drug moisture control, this design can rely on different drug ratios to achieve long-term maintenance of different specific humidity and realize two-way correction of over-humidity and over-dryness at the same time; therefore, this design has the advantages of active anti-humidity and anti-dryness, achieving constant humidity, and no manual maintenance.
