In summary, more specific embodiments of the present invention are:
an infectious disease hospital shelter roof exhaust system with the design structure needs to be installed as a standby before being used.
The specific installation steps are as follows:
firstly, an operator firmly welds the support frame 2 and the top frame and tightly attaches the support frame 2 and the top frame through the sealing plate 114 to form a top cover plate 11 structure which is fixedly connected;
then, an operator sequentially installs the cabin bottom plate 12, the side wall plate 13, the end wall plate 14 and the top cover plate 11 to complete assembly of the cabin body;
then, the operator lays the sealing strip 4 at the joint of the upper support frame 21 and the fresh air handling unit buckling frame 32, and lays C-shaped rubber strips 324 with slant bosses which can only move unidirectionally in the U-shaped grooves of the long buckling frame 321 and the short buckling frame 322;
next, an operator performs alignment connection on the extending parts on the side long beams 211 and the side short beams 212 and the U-shaped grooves of the long buckle frame 321 and the short buckle frame 322, performs alignment fastening on the drain holes 323 at four corners of the frame of the fresh air handling unit 3 and the alignment water guide holes 215 at the upper part of the support frame through the conical water guide pipe 6, and the rest parts can be locally reinforced in a riveting nut or a riveting mode according to the field condition;
and finally, an operator can realize the whole cabin assembly work by completing the tight installation of the air pipe unit 5 in the cabin according to the air inlet and the air return of the fresh air unit 3.
The specific application is as follows: when the cabin is in a negative pressure working environment, the air quantity of the air supply and return machines of the fresh air machine 3 is regulated according to the requirements of GBT 35428-2017 for controlling the environment of the negative pressure isolation ward of a hospital, and the air quantity of the air supply pipeline 51 is smaller than the air quantity of the air return pipeline 52 by detecting the air quantity in real time through an air quantity sensor until the required negative pressure condition is reached, so that the negative pressure working environment of the cabin can be realized.
Finally, after the use is finished with the lapse of time, when the maintenance or the dismantling of the indoor air duct unit 5 is required, an operator firstly dismantles the indoor air duct unit; then, the operator removes the water guide pipe 6, blind rivets and the like connecting the fresh air handling unit 3 with the upper supporting frame 21, and removes the fresh air handling unit 3; then, the operator takes away the sealing strip 4 paved at the joint of the upper supporting frame 21 and the fresh air handling unit buckling frame 32; finally, the top cover plate 11, the side wall plates 13, the end wall plates 14 and the cabin bottom plate 12 are sequentially taken away to finish the dismantling of the cabin system.
Finally, it should be noted that the above-mentioned embodiments illustrate rather than limit the invention in any way, and that those skilled in the art will be able to utilize the above-mentioned embodiments and modifications of the invention as well as equivalent embodiments. However, any simple modification, equivalent variation and variation of the above embodiments according to the technical substance of the present invention still fall within the protection scope of the technical solution of the present invention.
