In order to achieve the above purpose, the invention adopts the following technical scheme:

the mobile emergency laminar flow operating room air column support system comprises a plurality of linear air columns and a plurality of connecting devices, wherein part of the air columns are detachably connected end to end through the connecting devices to form a rectangular air column support body; the other part of the air columns are crossed pairwise to form an X-shaped reinforcing frame, and the middle part of the reinforcing frame is crossed and the end part of the reinforcing frame is connected with the bracket body through a connecting device to realize detachable connection; the rectangular bracket body is detachably connected with a reinforcing frame on at most three sides, and one side is reserved as an inlet and an outlet of the tent body.

when the air column is installed for the first time, in the factory prefabrication stage, firstly, the air column is inflated, then the air column is placed according to a preset position, and two adjacent upright posts are connected through a connecting device, so that an air column support system can be formed; then, the air column support system is connected with the awning body, so that a flowing emergency laminar flow operating room can be formed; after all the components are assembled, the air column is deflated, and the air column is folded and stored together with the awning body to form the final product. When the air column is actually applied by a customer, the air column is inflated, and the air column and the awning body are not required to be assembled on site; when in storage, the air column is deflated and is communicated with the tent body to be folded and stored together.

1. The support system is formed by the air columns, so that the support system and the awning body can be connected in a factory prefabrication stage, the air columns are directly inflated when in field use, the awning body can be automatically supported by the gradually filled air columns, support operation by workers is not needed, and the use safety can be effectively improved.

2. The air column is connected with the awning body in the factory prefabrication stage, so that when the air column is used on site, a laminar flow operating room for mobile emergency can be formed by only inflating the air column; when the air column is stored, the air column is only required to be deflated, and then the air column and the awning body are folded together for storage; the assembly and storage time of the flowing emergency laminar flow operating room is greatly shortened, the efficiency is effectively improved, the emergency and quick transfer are facilitated in time, and the field emergency efficiency is improved.

3. This scheme is through a plurality of connecting device with a plurality of air columns two by two connection, form rectangular support body, namely on the cross section of flow emergent laminar flow operating room, this scheme is through two vertical air columns and two horizontally air columns form rectangular frame's bearing structure, compare in adopting an arch air column as bearing structure on the cross section, this scheme can be applicable to the construction of small-size emergent laminar flow operating room that flows (because need keep great pressure in the air column just can guarantee supporting strength, consequently under the shorter circumstances of air column length, hardly buckle the air column into the arch), and small-size emergent operating room that flows is higher to the adaptability of topography, more be suitable for the scene rescue after serious natural disasters such as earthquake take place.

4. After this scheme adopts the air column equipment to form cuboid support body, set up the enhancement frame on at most three side of support body again, can effectively improve whole air column support system's structural strength, guarantee that it carries out stable support to the fluffy body in the use to improve the safety in utilization of emergent laminar flow operating room that flows.

5. According to the scheme, the two air columns are detachably connected through the connecting device to form an X shape, compared with other shapes, the X-shaped reinforcing frame has good shearing resistance, the two air columns arranged in the X shape support the side face of the support body in a shearing manner, so that the side face shock resistance of the support body can be improved, and the structural strength of the whole air column support system is improved; in addition, the X-shaped reinforcing frame is formed by connecting two linear air columns, compared with the air column directly processed into the X-shaped, firstly, the manufacturing is more convenient, secondly, stress concentration is not easy to generate when the air column directly processed into the X-shaped is inflated (concentrated stress is easy to generate at the intersection in the inflation process, if the structural strength of the air column is not reached, the air column is easy to tear), the air column can be prevented from being damaged in the inflation process, and therefore the service life of the air column is effectively prolonged.

6. The connection device is adopted between every two air columns in the scheme to carry out detachable connection, when one or more air columns are damaged, the air columns can be replaced in a targeted mode, so that the service life of the whole air column support system is guaranteed, the whole air column support system is not required to be replaced, and replacement cost of equipment is reduced.
