Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The dual-mode movable isolation cabin comprises a sealed cabin formed by cabin doors of a cabin body, a blowing device and a pollutant purifying device, wherein the sealed cabin comprises a first ventilation port and a second ventilation port, and the first ventilation port and the second ventilation port are arranged diagonally in the cabin body. The pollutant purification device is arranged between the external interface of the air blowing device and the first air exchange port, and can purify air entering the sealed cabin when the air blowing device blows air into the sealed cabin; the pollutant purifying means may purify air exiting the capsule while the air blowing means is drawing air out of the capsule. When the air blowing device wants to blow air into the sealed cabin, the air pressure in the sealed cabin is greater than the external air pressure, so that external pollutants cannot enter the sealed cabin; when the air blowing device pumps air out of the sealed cabin, the air pressure in the sealed cabin is smaller than the external air pressure, so that the air in the sealed cabin cannot be leaked to the outside.
The technical scheme is further explained in the following with the accompanying drawings. Referring to fig. 1 to 3, fig. 1 is a schematic structural view of a dual mode movable isolation chamber provided according to the present disclosure, fig. 2 is a partially enlarged view at a blower device in fig. 1, and fig. 3 is a partially enlarged view at a second transfer port 804 in fig. 1.
The dual-mode movable isolation chamber comprises a sealed chamber 4 consisting of a chamber door (not shown) and a chamber body, a pollutant purifying device 1 and a blowing device 105. The cabin body is also provided with a glass window 6, a delivery window 10, a first ventilation port 102 and a second ventilation port 804, and the cabin body is also internally provided with an ultraviolet irradiation device 7 and a garbage can 11. A plurality of caster wheels 12 are arranged below the cabin body, a handle 5 is arranged on the side of the cabin body, and an operation panel 9 is arranged on the outer surface of the cabin body. A hatch door (not shown) is located opposite the wall on which the glazing 6 is located.
The sealed cabin 4 comprises a cabin body, a cabin door (not shown), a first ventilation port 102 and a second ventilation port 804, wherein the cabin door is sealed with the cabin body when closed, and the cabin body and the cabin door form an isolated space together. The sealed cabin 4 is roughly a cuboid structure, the first ventilation port 102 is positioned below the side of the cabin body, the second ventilation port 804 is positioned above the other side of the cabin body, and the two ventilation ports are roughly diagonally arranged in the cabin body. The first transfer ports 102 are used to connect with the blower device 105, and the second transfer ports 804 are used to communicate with the outside when air is supplied or discharged from the first transfer ports 102, and of course, the second transfer ports 804 communicate with the outside but are also provided with a physical barrier to filter air and provide some damping.
The opening direction of the first air exchange port 102 is horizontal direction, and in order to prevent liquid (such as condensed water or disinfection spray) from the surface of the cabin wall of the sealed cabin 4 from flowing into the space between the first air exchange port 102 and the external interface of the air blowing device through the first air exchange port 102, the pollutant purifying device 1 is provided with a waterproof baffle plate 101 at the first air exchange port 102. The waterproof baffle 101 is a slightly inclined vertical plate, the bottom of which is connected to the bottom plate inside the sealed cabin 4, and the whole of which is inclined to the outside of the first ventilation port 102, so that the top of the waterproof baffle is positioned outside the first ventilation port 102. Thus, if liquid flows to the first ventilation port 102 along the inner wall of the sealed cabin 4, the dropped liquid drops will fall on the waterproof baffle 101 and flow back into the sealed cabin 4, and will not reach the outside of the sealed cabin 4. The waterproof baffle 101 changes the form of the first ventilation opening 102, and forms a channel for changing the direction of the gas flow together with the first ventilation opening 102, wherein the gas can normally pass through the channel, and the liquid cannot pass through the channel. Therefore, providing a waterproof structure such as a U-shape or a Z-shape can also block the liquid from flowing out.
The air blowing device 105 comprises an external interface, the external interface is hermetically connected with the first ventilation port 102 of the sealed cabin 4, and the air flow generated by the air blowing device 105 can enter and exit the sealed cabin 4 through the external interface and the first ventilation port 102. The power unit in the blower device 105 may cause the blower device 105 to generate airflows in different flow directions, and the blower device 105 may either draw air from the capsule 4 or blow air into the capsule 4.
The pollutant purifying device 1 comprises two parts, a high efficiency filter 103 and a chemical gas filter 104, which are arranged between the air blowing device 105 and the first ventilation opening 102, so that both the gas coming out from the external interface of the air blowing device 105 and the gas entering the air blowing device 105 from the first ventilation opening 102 can be filtered and purified. That is, the air taken into the capsule 4 is cleaned when the air blowing device 105 blows air into the capsule 4, and the air taken out of the capsule 4 is cleaned when the air blowing device 105 draws air out of the capsule 4. The pollutant purification device 1 is arranged in a small compartment, and the compartment is communicated with the outside through an air inlet and outlet shutter 2.
The second ventilating opening 804 is provided with an air filtering device, which is a dust filtering non-woven fabric 803 in this embodiment. The second scavenging port 804 is further provided with a pressure regulating device 8, and the pressure regulating device 8 can change the minimum cross-sectional size of the air flow passage of the second scavenging port 804, so as to control the pressure in the sealed cabin 4. Specifically, the pressure regulating device 8 includes a pressure regulating plate 801 and an air volume regulating seat 802, the air volume regulating seat 802 is fixed on the wall body of the sealed cabin 4 and is communicated with the second scavenging port 804, and an opening (for example, a half area is provided with a round hole) is arranged on the air volume regulating seat 802, and the opening and the second scavenging port 804 together form a scavenging passage. The pressure regulating plate 801 is provided with an opening area (for example, a half area is provided with a circular hole), the pressure regulating plate 801 is rotatably arranged on the air volume adjusting seat 802, and the overlapping range of the opening area of the pressure regulating plate 801 and the opening of the air volume adjusting seat 802 can be changed when the pressure regulating plate 801 rotates, so that the ventilation cross-sectional area of the whole second ventilation port 804 can be changed. The smaller the ventilation cross-sectional area of the second transfer port 804, the larger the wind resistance, and the larger the difference between the internal air pressure and the external air pressure.
In some alternative embodiments, the pressure regulating plate 801 is provided in a drawing sliding manner, and the pressure regulating plate 801 can slide along the surface of the air volume adjusting seat 802, so as to adjust the overlapping area of the openings of the two; alternatively, the air volume adjusting seat 802 is not provided, and the pressure adjusting plate 801 directly slides on the outer surface of the capsule 4.
The transfer window 10 is the required operating window of inside personnel of sealed cabin 4 and outside personnel's transmission article, and transfer window 10 includes a short channel and sets up two adjustable fender at the short channel both ends, and on the whole embedding sealed cabin 4's of transfer window 10 lateral wall, the passageway direction is the horizontal direction, is the object space in the passageway. The movable baffle can be a glass window and can be in a side push-pull switch type structure. When sending the thing through the pass-through window, open outside baffle by external personnel, close outside baffle after placing article, then inside personnel open inside baffle, get the thing, close inside baffle again. When the articles are transferred outwards, the whole process is reversed. The object is delivered by using the delivery window, so that direct contact between internal personnel and external personnel can be prevented, the exchange and circulation of air inside and outside the sealed cabin 4 are reduced, and air brought-in pollution in the delivery process is prevented.
The ultraviolet irradiation device 7 is used for sterilizing the cabin environment. The ultraviolet irradiation device 7 is arranged in the sealed cabin 4 and is set such that after the interior protection or epidemic prevention personnel leave and the knob of the air blowing device is switched to stop, the ultraviolet irradiation device 7 is opened and is closed after irradiating for a certain time, thereby achieving the purpose of automatic disinfection and sterilization.
The pressure difference detection device 3 is arranged between the inner environment and the outer environment of the sealed cabin 4 and can simultaneously detect the air pressure of the inner environment and the outer environment. The pressure difference detection device 3 can monitor the air pressure in the sealed cabin 4 in real time, and when the air pressure in the sealed cabin 4 is larger than or smaller than a set threshold value, a signal can be sent out, so that the sound-light alarm lamp 903 sends out an alarm indication, and the key operation state of the system is ensured to be mastered in real time. In the positive pressure state, the pressure inside the capsule 4 should be higher than the outside atmospheric pressure, and the alarm threshold may be set to be slightly higher than the standard atmospheric pressure. In the negative pressure state, the internal pressure of the capsule 4 should be lower than the external pressure, and the alarm threshold may be set slightly lower than the standard atmospheric pressure. Of course, the atmospheric pressure outside the sealed cabin 4 can also be monitored in real time, and the two real-time pressures are compared and used as the alarm basis.
In the embodiment, the walking wheel device is a plurality of casters 12, and an external person can push the sealed cabin 4 to walk.
