[0040] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0041] The present invention provides a modular biosafety buffer corridor, such as Figure 1-2 As shown, it comprises: a first cabin 1 and a second cabin 2, wherein a first opening 3 is provided on one end of the first cabin 1, a buffer chamber 4 is provided in one end of the second cabin 2, a slide buffer room 5 is provided in the buffer room 4, a second opening 6 is provided on the side wall of the second cabin 2, the second opening 6 is communicated with the buffer chamber 4, and the slide buffer room 5 can pass through the second opening 6 and extend into the first opening 3.

The bottom of the cabin is equipped with movable wheels that can be raised and lowered like aircraft landing gear, which is convenient for quick folding after being put in place, and also convenient for moving and transporting after disassembly. The cabins can be combined in various forms, and the square cabins can be quickly combined into multiple warehouses to quickly form field hospitals, conjoined testing rooms, conjoined hospitals, etc.

[0043] In one embodiment, the first cabin 1 and the second cabin 2 are both in the shape of a cuboid, and the end surface area of ​​the cabin is large, which can facilitate the rapid connection between the cabins.

[0044] In one embodiment, passage doors 7 are respectively provided at both ends of the buffer room 5 to facilitate the sealing between the cabins.

[0045] In one embodiment, a door 8 is provided on the outer wall of the second cabin 2 at the buffer chamber 4 to facilitate experimenters to enter and exit the cabin.

[0046] In one embodiment, Figure 3 As shown, a first connecting plate 9 is provided on the outer wall of one end of the slide buffer room 5 close to the first opening 3, and the first connecting plate 9 is connected to the outer wall of the first cabin body 1 by screws. A baffle 10 is provided on the outer wall of one end of the slide buffer room 5 away from the first connecting plate 9, and the cross-sectional size of the baffle 10 is larger than the cross-sectional size of the second opening 6.

[0047] The working principle and beneficial technical effects of the above technical solution are as follows: the first connecting plate 9 and the baffle plate 10 can block the first opening 3 and the second opening 6 to improve the sealing effect.

[0048] In one embodiment, a sealing ring 11 is provided on the baffle 10. The sealing ring 11 is a modular silicone sealing ring, which can ensure that the double warehouses and multiple warehouses can be sealed sequentially after docking. After sealing, a pressure holding test can be carried out, and the pressure drop in half an hour is less than or equal to 10Pa.

[0049] In one embodiment, Figure 4-7 As shown, a ventilation device is provided on the first cabin 1, and the ventilation device comprises:

[0050] An air duct 12, wherein a fan 32 is disposed at one end of the air duct 12, the other end of the air duct 12 is connected to the first cabin 1, and a filter 13 is disposed at one end of the air duct 12 close to the first cabin 1;

[0051] A box body 14, wherein the bottom end of the box body 14 is connected to the outer wall of the air duct 12, the top end of the box body 14 is connected to one end of a support rod 15, and the other end of the support rod 15 is connected to the outer wall of the first cabin body 1;

[0052] A fixing plate 16, the fixing plate 16 is arranged in a vertical direction, and the top of the fixing plate 16 is connected to the top of the inner wall of the box body 14 through a first connecting rod 17;

[0053] A flat plate 18, the flat plate 18 is arranged in a horizontal direction, one end of the flat plate 18 is connected to the inner wall of the box body 14, and the other end of the flat plate 18 is connected to the fixed plate 16. A motor 19 is arranged on the flat plate 18, and the output shaft of the motor 19 is connected to one end of a first rotating shaft 20, and the other end of the first rotating shaft 20 passes through the fixed plate 16 and is connected to one end of a rotating plate 21, and the first rotating shaft 20 is rotatably connected to the fixed plate 16;

[0054] A second rotating shaft 22, one end of which is rotatably connected to the lower end of the fixed plate 16, and the other end of which is connected to the center of a circular plate 23, wherein a plurality of eccentric columns 25 are evenly spaced along the circumferential direction of the circular plate 23;

[0055] A shift fork 24 is disposed between the rotating plate 21 and the circular plate 23. A guide opening 26 is disposed at the upper end of the shift fork 24. A clamping slot 27 is disposed at the lower end of the shift fork 24. The clamping slot 27 extends along the length direction of the shift fork 24. A fixing column 28 is disposed between the guide opening 26 and the clamping slot 27. One end of the fixing column 28 is connected to the shift fork 24. The other end of the fixing column 28 is rotatably connected to an end of the rotating plate 21 away from the first rotating shaft 20. The second rotating shaft 22 passes through the clamping slot 27. The eccentric column 25 extends into the guide opening 26.

[0056] The second connecting plate 29 is arranged in a horizontal direction, one end of the second connecting plate 29 is connected to the bottom end of the fork 24, the bottom end of the second connecting plate 29 is connected to one end of the second connecting rod 30, a limiting opening 33 extending along the width direction is arranged on the top end of the air duct 12, the other end of the second connecting rod 30 passes through the limiting opening 33 and extends into the air duct 12, and is connected to the brush 31, and the brush 31 is in contact with the filter 13.

[0057] The working principle and beneficial technical effects of the above technical solution are as follows: the fan 32 is started to suck the external air into the air duct 12, and then the fresh air is delivered to the first cabin 1 after being filtered by the filter 13. After long-term use, dust or foreign matter will accumulate on the surface of the filter 13. The motor 19 is started to drive the first rotating shaft 20 to rotate, and the first rotating shaft 20 drives the rotating plate 21 to rotate, and the rotating plate 21 drives the fixed column 28 to rotate around the first rotating shaft 20. Since the second rotating shaft 22 is stuck in the slot 27 at the lower end of the fork 24, the fork 24 moves up and down while swinging, so that the guide port 26 at the upper end of the fork 24 is stuck on an eccentric column 25 and is toggled, and then inserted into another eccentric column 25 for toggling, thereby realizing the intermittent rotation of the circular plate 23; at the same time, the second connecting plate 29, the second connecting rod 30, and the brush 31 connected to the lower end of the fork 24 move up and down while swinging, and the brush 31 can clean the surface of the filter 13. Since the brush 31 can move up and down while swinging, only a small-sized brush is needed to clean the entire surface of the filter 13. During the cleaning process, the brush 31 only occupies a very small surface area of ​​the filter 13, so the impact on the ventilation flow during the cleaning process is small. Moreover, since the brush has a large range of motion, it can also clean the entire filter surface.

[0058] In one embodiment, Figure 8 As shown, a disinfection device is provided on the outer wall of the first cabin 1, and the disinfection device comprises:

[0059] An air delivery pipe 34, the air delivery pipe 34 is arranged between the box body 14 and the first cabin body 1, one end of a third connecting rod 35 is connected to the outer wall of the box body 14, and the other end of the third connecting rod 35 is connected to the outer wall of the air delivery pipe 34, the upper end of the air delivery pipe 34 is closed, and the lower end of the air delivery pipe 34 is connected to the air duct 12;

[0060] A second rotating shaft 36, one end of which is connected to the center of the circular plate 23, and the other end of which passes through the wall of the box 14 and the wall of the air delivery pipe 34 in sequence, extends into the air delivery pipe 34, and is connected to a plurality of fan blades 37;

[0061] An air storage box 38 is arranged at the top of the air supply pipe 34, and an air outlet 39 is arranged at the bottom of the air storage box 38, and the air outlet 39 is connected to the air supply pipe 34. The top of the air storage box 38 is connected to one end of the air pipe 40, and the other end of the air pipe 40 is connected to the gas tank, and the gas tank is filled with medical disinfection gas;

[0062] A moving rod 41 is arranged above the fan blade 37. A first sleeve 42 and a second sleeve 43 are respectively arranged on the left and right sides of the top of the inner wall of the air delivery pipe 34. One end of the moving rod 41 passes through the first sleeve 42 and is connected to the first limit block 44. The other end of the moving rod 41 passes through the second sleeve 43 and is connected to the second limit block 45. The moving rod 41 can reciprocate left and right.

[0063] A moving block 46 is disposed on the moving rod 41, and the moving block 46 is located between the first sleeve 42 and the second sleeve 43. An elastic protrusion 47 is disposed on the top of the moving block 46, and the elastic protrusion 47 can block the air hole 39. The side wall of the lower end of the moving block 46 can contact the fan blade 37;

[0064] The spring 48 is sleeved on the moving rod 41 , one end of the spring 48 is connected to the second sleeve 43 , and the other end of the spring 48 is connected to the moving block 46 .

[0065] The working principle and beneficial technical effects of the above technical solution are as follows: when the brush is cleaning the filter screen, the circular plate 23 performs intermittent rotational motion, and accordingly, the circular plate 23 drives the second rotating shaft 36 and the fan blade 37 to perform intermittent rotational motion. When the fan blade 37 rotates, it drives the moving block 46 to move leftward, and the elastic protrusion 47 will separate from the air hole 39, and the disinfection gas in the air storage box 38 will be input into the air supply pipe 34 through the separation air hole 39. When the fan blade 37 separates from the moving block 46, the elastic force of the spring 48 pulls the moving block 46 to move rightward, so that the elastic protrusion 47 is disengaged from the air hole 39. The elastic protrusion 47 is squeezed into the air hole 39 to block it, and the next fan blade 37 will open the air hole 39 again; through the intermittent rotation of the blade 37, the disinfection gas of the air hole 39 is also intermittently supplied. Since the brush will sweep down some bacteria or dust during the swing cleaning process, the higher the brushing frequency, the higher the opening frequency of the air hole 39, thereby correspondingly improving the disinfection efficiency of the gas. When the brushing frequency is reduced, the opening frequency of the air hole 39 is also lower, which reduces the disinfection efficiency of the gas, thereby saving the disinfection gas. When the cleaning device is closed, since there is no movement of the blade 37, the elastic protrusion 47 will block the air hole 39 to prevent the leakage of the disinfection gas and cause waste.

[0066] In one embodiment, a valve 49 is provided on the air pipe 40 .

[0067] The working principle and beneficial technical effects of the above technical solution are as follows: the valve 49 is used to control the opening or closing of the air pipe 40. When not in use for a long time, the valve 49 is closed to prevent the disinfecting gas in the gas cylinder from entering the gas storage box 38 through the air pipe 40.

[0068] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
