Description

Technical Field

[0001] This utility model relates to the field of archaeological environmental control and protection, and in particular to a constant oxygen, constant temperature and constant humidity archaeological excavation container. Background Technology

[0002] Before being unearthed, cultural relics exist in a relatively stable underground environment where environmental parameters such as temperature, humidity, and oxygen concentration remain constant. Once exposed to air, the drastic changes in environment can easily lead to irreversible damage such as oxidation, deformation, and cracking. This is especially true during the excavation of relics under demanding preservation conditions, where traditional protective measures often fall short. Therefore, it is necessary to provide a stable environment for cultural relics during archaeological excavations to protect them from external influences. Currently, steel-structured sheds are commonly used to protect the excavation site. However, the supporting columns of these sheds typically require excavation to a certain depth to lay the foundation, which may potentially damage the underground artifacts.

[0003] Chinese utility model patent CN219034178U, published on May 16, 2023, discloses an archaeological conservation shed. The shed includes a frame-shaped bottom beam and a support frame fixedly supported on the bottom beam. A counterweight structure is installed on the bottom beam, and a closed cover is installed on the top and sides of the support frame. The shed is fixed by the counterweight structure on the bottom beam, thus eliminating the need to dig a deep pit and avoiding damage to underground cultural relics. However, the bottom of the shed is not sealed, and the internal environment of the shed is still connected to the external environment.

[0004] Furthermore, the use of portable temperature and humidity control devices can provide temporary environmental control at the excavation site, preventing damage to cultural relics due to environmental changes. Currently, some large-scale archaeological projects in China have begun to use corresponding equipment to control the environment at the excavation site. This equipment can maintain a constant temperature, humidity, and oxygen environment at the archaeological excavation site. However, achieving such an environment requires a sealed space, therefore, the archaeological excavation site needs to be sealed off. Utility Model Content

[0005] The purpose of this invention is to provide a constant-oxygen, constant-temperature, and constant-humidity archaeological excavation cabin to solve the problem that existing archaeological sheds cannot be sealed, thus making it impossible to achieve a constant-temperature, constant-humidity, and constant-oxygen environment at the archaeological excavation site.

[0006] The constant oxygen, temperature, and humidity archaeological excavation container of this utility model adopts the following technical solution:

[0007] The constant oxygen, temperature, and humidity archaeological excavation container includes a container body, which includes a container frame. The top and sides of the container frame are equipped with sealing plates for sealing the top and sides of the container body. The container frame includes a bottom beam and a top beam, as well as support columns installed between the bottom beam and the top beam. The bottom beam is a steel box beam with a set height to meet the requirements of soil sealing. A sealing plate at least as long as the bottom beam is fixedly installed on the underside of the bottom beam for inserting into the lower soil layer to seal the bottom of the container body. The sealing plate is located on the underside of the bottom beam along the extension direction of the bottom beam.

[0008] Furthermore, the sealing plate is fixedly installed on the underside of the bottom beam, and the sealing plate is fixedly installed at the middle position in the thickness direction of the bottom beam.

[0009] Furthermore, fixed guide rails extending along the bottom beam are installed on the bottom beam to enable the crane inside the cabin to move within the cabin.

[0010] Furthermore, reinforcing ribs are provided inside the bottom beam.

[0011] Furthermore, a constant oxygen, temperature and humidity system is installed inside the chamber to control the environment inside the chamber to maintain a stable state.

[0012] Furthermore, the cabin includes an entrance cabin, an excavation cabin, and an artifact turnover cabin. The entrance cabin and the artifact turnover cabin are located at both ends of the excavation cabin, and an openable and closable door is provided at the connection between the entrance cabin and the artifact turnover cabin and the excavation cabin.

[0013] Furthermore, a gantry crane is provided inside the cabin, and the gantry crane is mounted on a fixed guide rail.

[0014] Furthermore, the enclosure panels around the perimeter and top of the cabin frame are all-glass curtain walls.

[0015] Furthermore, the top of the cabin is cone-shaped.

[0016] Furthermore, a water collection trough is provided on the inner side of the top beam of the cabin frame to prevent condensation generated on the cabin from dripping and damaging the cultural relics.

[0017] Beneficial Effects: This utility model of a constant-oxygen, constant-temperature, and constant-humidity archaeological excavation container is an improved invention. The bottom beam of this container is a steel box girder structure, eliminating the need for deep pit excavation and prefabrication, thus preventing damage to underground artifacts. The sealing plates on the top and sides of the container frame provide a seal. A sealing plate at least as long as the bottom beam is installed below the bottom beam, which is inserted into the underlying soil layer to seal the bottom of the container. This utility model of a constant-oxygen, constant-temperature, and constant-humidity archaeological excavation container eliminates the need for deep pit excavation, preventing damage to underground artifacts, while simultaneously ensuring overall airtightness by sealing the bottom of the container.

[0023] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0024] This invention addresses the problem that existing archaeological sheds are not completely sealed, thus failing to achieve a constant temperature, humidity, and oxygen environment at the archaeological excavation site. Specifically, it proposes a constant oxygen, temperature, and humidity archaeological excavation cabin. The bottom beam of this cabin is a steel box girder structure, with a sealing plate inserted into the soil layer on the lower end face of the bottom beam to ensure the bottom of the cabin is sealed, achieving overall sealing and ensuring the interior of the cabin is a closed space.

[0025] In one basic embodiment, sealing plates are installed on the top and sides of the cabin frame to seal the top and sides of the cabin. The bottom beam 11 of the cabin frame adopts a steel box beam structure, and the support column 4 of the cabin frame is installed between the bottom beam 11 and the top beam 10. A sealing plate 7 is installed on the underside of the bottom beam 11 and is inserted into the soil below the bottom beam. The constant oxygen, temperature and humidity archaeological excavation cabin of this utility model does not require excavation and pouring of concrete to build a foundation, thus avoiding damage to underground cultural relics. During the installation of the cabin, the soil at the bottom of the cabin is leveled, and soil adhesive is mixed into the top of the soil layer. Then, the bottom beam 11 of the cabin is placed on the soil. A sealing plate 7 of the same length as the bottom beam 11 is installed below the bottom beam 11 and inserted into the soil layer below the bottom beam to ensure the sealing effect of the bottom of the cabin. The sides of the bottom beam 11 are covered with soil for sealing. The lateral pressure of the soil on the bottom beam 11 enhances the sealing effect.

[0026] In other embodiments, the length of the sealing steel plate installed below the bottom beam is greater than the length of the bottom beam. The sealing steel plate is inserted into the soil layer below the bottom beam, which can also ensure the sealing effect of the bottom of the cabin.

[0027] In a preferred embodiment, the sealing plate 7 installed at the lower end of the bottom beam 11 is installed at the center position of the wall thickness direction on the lower side of the bottom beam. After the soil is covered on both sides of the bottom beam, the pressure on both sides of the sealing plate 7 can be consistent, which can better achieve the sealing effect on the bottom of the cabin.

[0028] In other embodiments, the sealing plate 7 may not be installed in the middle of the lower end face of the bottom beam of the cabin. After the bottom beam is covered with soil, it can still achieve the effect of sealing the bottom of the cabin.

[0029] In a preferred embodiment, such as Figure 2 As shown, a fixed guide rail 5 is fixedly installed on the upper surface of the bottom beam. The crane inside the cabin can be installed on the fixed guide rail 5, which facilitates the movement of the crane inside the cabin, and also facilitates the staff to reach the archaeological excavation site to carry out archaeological excavation work, as well as facilitates the transfer of the excavated cultural relics.

[0030] In a preferred embodiment, a reinforcing rib 6 of a certain thickness is provided inside the bottom beam, which can further strengthen the bottom beam structure, improve the support capacity of the bottom beam, and ensure the stability of the cabin structure.

[0031] In a preferred embodiment, a constant oxygen, temperature, and humidity system is installed inside the chamber. This system controls the internal environment of the chamber, maintaining a constant oxygen, temperature, and humidity level similar to that before the artifact was unearthed. This ensures that the artifact remains in a stable environment during archaeological excavation, preventing irreversible damage caused by external environmental factors. The constant oxygen, temperature, and humidity system is a publicly available technology, and the number of such systems can be varied depending on the size of the chamber.

[0032] In a preferred embodiment, such as Figure 1 , 3As shown in Figure 4, the excavation chamber includes an entrance chamber 1, an excavation chamber 2, and an artifact transfer chamber 3. The artifact transfer chamber 3 and the entrance chamber 1 are connected to the left and right ends of the excavation chamber 2, respectively. A constant oxygen, temperature, and humidity control system is installed inside the excavation chamber 2 to ensure a stable environment for the artifacts. An openable and closable door connects the entrance chamber 1 and the excavation chamber 2. The entrance chamber 1 contains a command room, a buffer zone, an air shower area, a central control room, and a changing room. After entering the main hall, staff go to the changing room to put on their specialized archaeological equipment, pass through the air shower for cleaning, and then enter the buffer zone. Once the environmental parameters in the buffer zone are consistent with those in the excavation area, the door is opened to enter the excavation chamber. An openable and closable door connects the artifact transfer chamber 3 to the excavation chamber 2, allowing for the transfer of large excavated artifacts in a constant oxygen, temperature, and humidity environment.

[0033] In a preferred embodiment, a gantry crane 8 is installed inside the excavation chamber 2. The gantry crane 8 is mounted on a fixed guide rail 5 and can move on the fixed guide rail 5 to facilitate the staff to reach the predetermined work area. It can also be used to transfer the excavated cultural relics.

[0034] In a preferred embodiment, a full-glass curtain wall is provided around the perimeter and top of the cabin frame. The full-glass curtain wall is sealed to the cabin frame to achieve the sealing of the cabin. At the same time, the use of the glass curtain wall facilitates the real-time recording of the archaeological excavation inside the cabin.

[0035] In other embodiments, metal plates can be installed on the cabin frame to seal the cabin, and the use of an all-metal structure for the cabin can make the cabin structure more robust.

[0036] In a preferred embodiment, the top of the cabin is a pointed conical structure, which can prevent water from accumulating on the top of the cabin and allow condensate to flow down along the top of the cabin.

[0037] In other embodiments, the top of the chamber can be a spherical structure, which also allows condensate to flow down the top of the chamber.

[0038] In a preferred embodiment, a water collection tank 9 is provided on the inner side of the top beam of the cabin frame. The water collection tank 9 can collect the condensate generated on the top of the cabin and prevent the condensate generated on the cabin from dripping and damaging the cultural relics.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
