Abstract

[0002] People from plains areas often experience severe altitude sickness when entering high-altitude areas. Low air pressure leads to low oxygen concentrations; at an altitude of 4000m, the incidence of altitude sickness exceeds 50%. Altitude sickness is essentially a series of adverse symptoms caused by hypoxia due to decompression. It can be mitigated by increasing the partial pressure of oxygen, thus improving the body's oxygen utilization and avoiding the harmful effects of low-pressure hypoxia.
[0003] Currently, the construction and operating costs of pressurized buildings on the market are relatively high. For example, the sales price of China Railway Construction Heavy Industry's "Plateau Space Station" and China Construction Third Engineering Bureau's "Zero Altitude House" are both around 30,000 yuan / ㎡, while the sales price of Hongtai Medical's hyperbaric oxygen chamber products is around 20,000 yuan / ㎡. Faced with current market demands and industry pain points, it is urgent to find ways to innovate new products through new materials and structural technologies to reduce construction and operating costs.

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description
[0015] Figure 1 This is a cross-sectional schematic diagram of the pressurized building in the plateau region based on the air-supported membrane structure in this invention.
[0016] Figure 2 This is a top view of the pressurized building in the plateau region based on the air-supported membrane structure in this invention. Detailed Implementation
[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0019] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.
[0020] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.
[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0022] like Figure 1-2 As shown, a preferred embodiment of the present invention provides a pressurized building for plateau regions based on an air-supported membrane structure, comprising: Building Main Structure 1; The membrane body 2 encloses the building body 1, and the pressure between the building body 1 and the membrane body is maintained at 10-15 kPa.
[0023] In the above technical solution, the entire pressurized building can simulate a low-altitude environment by maintaining a pressure difference of 10-15 kPa between the inside and outside of the building, thus helping the human body adapt to high-altitude hypoxia.
[0024] Moreover, this pressurized building only requires the main building body and the membrane body, reducing the complex support structure of traditional buildings. The main building body can take many forms, such as a movable building, commonly a shipping container or a prefabricated house.
[0025] Using shipping containers or prefabricated houses as the main building structure facilitates standardized production and rapid deployment, reducing construction costs by utilizing existing mature products. Furthermore, they can be quickly disassembled and assembled, minimizing on-site construction time.
[0026] According to a preferred embodiment of the present invention, the main building 1 is set on the ground, and the bottom end of the membrane body 2 is sealed and connected to the ground to prevent the entry of low-oxygen air from the outside and improve indoor air quality. Furthermore, by enclosing the main building 1 inside the membrane body 2, there is no contact between the main building 1 and the membrane body 2, thus avoiding structural interference and improving spatial flexibility.
[0027] According to a preferred embodiment of the present invention, the membrane body 2 adopts a reinforced cable membrane structure. The reinforced cable membrane structure can effectively disperse membrane surface stress, improving the overall structural stability and resistance to wind and snow. The reinforced design of the cable membrane structure can reduce local stress concentration in the membrane material and extend the membrane's service life.
[0028] The shape memory alloy used to fabricate the reinforcing cable-membrane structure is a nickel-titanium alloy. By applying an electric current to the shape memory alloy cable, it undergoes a shape change, automatically adjusting the tension and shape of the membrane surface to enhance the structure's disaster resistance. Under strong winds, the cable contracts, reducing the windward area of the membrane surface; during heavy snowfall, the cable stretches, increasing the slope of the membrane surface to facilitate snow sliding off.
[0029] The nickel-titanium alloy cable structure is divided into multiple zones according to function and location, with each zone corresponding to a different current control level. Higher current control precision and a wider current adjustment range are set on the windward side of the membrane structure and in critical areas prone to snow accumulation; relatively lower control precision and a smaller current adjustment range are used in less critical areas. When encountering strong winds, the current in the windward zone increases rapidly, causing the cable structure to contract quickly and enhance wind resistance, while the current in other zones is adjusted appropriately according to the actual situation to ensure coordinated deformation of the overall structure and avoid unnecessary energy consumption.
[0030] According to a preferred embodiment of the present invention, the system further includes an in-membrane ventilation system, a pressurization system, and a pressure relief system. The ventilation system is used to circulate the gas between the building body and the membrane body to the outside environment. The pressurization system is used to inflate the space between the membrane body and the building body. The pressure relief system is used to discharge the gas between the membrane body and the building body.
[0031] The ventilation system allows for indoor and outdoor air circulation, preventing indoor oxygen concentrations from becoming too high or too low. The pressurization system can quickly adjust pressure as needed to ensure environmental stability.
[0032] It also includes a graded pressure regulation module, which automatically switches between three pressure modes—acute phase (14-15 kPa), acclimatization phase (12-14 kPa), and stable phase (10-12 kPa)—based on the personnel's arrival time. Specifically, during the first 1-3 days at high altitude, the pressure between the main building 1 and the membrane structure is maintained at 14-15 kPa; during the 3-7 days at high altitude, the pressure is maintained at 12-14 kPa; and after 7 days at high altitude, the pressure is maintained at 10-12 kPa.
[0033] According to a preferred embodiment of the present invention, the device further includes a pressure sensor and a PLC controller, wherein the pressure sensor is used to monitor the pressure difference between the inside and outside of the membrane in real time. The PLC controller is connected to the pressure sensor and the stamping system; When the pressure sensor detects that the pressure difference between the inside and outside of the membrane body is higher than a preset range, the PLC controller controls the stamping system to start and discharge gas between the membrane body and the building body until the pressure difference between the inside and outside of the membrane body reaches the preset pressure difference range.
[0034] According to a preferred embodiment of the present invention, a pressure regulating transition access system is further included, comprising: a pressure regulating chamber 3, a pressurization control module, a pressure relief control module, and a pressure regulating chamber door. One end of the pressure regulating chamber is connected to the interior of the building structure through a sealed channel made of a flexible sealing material. The other end of the pressure regulating chamber is connected to the external environment through a sealed door. The sealed door adopts a multi-layer sealing structure to ensure effective isolation of external low-oxygen air when closed. The pressurization control module includes an inflation blower and an inflation pressure regulating valve. The inflation blower is connected to the inside of the pressure regulating chamber through an inflation pipeline. An inflation pressure regulating valve is installed on the inflation pipeline to control the pressure changes during the inflation process. The pressure regulating valve is controlled by a PLC controller. The pressure relief control module includes an exhaust fan and an exhaust pressure regulating valve. By opening the exhaust pressure regulating valve, exhaust pressure relief is achieved. The PLC controller is connected to the pressurization control module, the depressurization control module, and the pressure sensor in the pressure regulating room.
[0035] Workflow Personnel entry: Personnel enter the pressure regulating room from the external environment and close the sealed door on the outside of the pressure regulating room.
[0036] The main controller module starts the pressurization control module, which uses an air blower to pressurize the pressure regulating chamber, gradually increasing the air pressure inside the chamber until it matches the air pressure inside the main building.
[0037] Once the air pressure inside the pressure regulating room is balanced with the air pressure inside the main building, the main controller module sends a signal to open the sealed door inside the pressure regulating room, allowing personnel to enter the main building. Personnel departure: Personnel enter the pressure regulating room from inside the main building and close the sealed door on the inside of the pressure regulating room.
[0038] The main controller module activates the pressure relief control module, which uses an exhaust fan to discharge the gas in the pressure regulating chamber, gradually reducing the air pressure inside the chamber to match the external ambient air pressure.
[0039] Once the air pressure inside the pressure regulating room is balanced with the external ambient air pressure, the main controller module sends a signal to open the sealed door on the outside of the pressure regulating room, allowing personnel to leave the pressure regulating room.
[0040] Furthermore, it should be noted that the main body of the membrane is a graphene oxide membrane. This graphene oxide membrane is immersed in a glycerol solution in a vacuum environment. In the vacuum environment, glycerol molecules will enter between the graphene oxide sheets, increasing the interlayer spacing and thus weakening the interlayer interaction. The treated graphene oxide membrane is then stretched. During the stretching process, relative movement will occur between the graphene oxide sheets, causing the microstructure of the membrane to align, increasing the crystallinity of the membrane, and thus improving the tensile strength of the membrane.
[0041] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
