Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1 As shown, in one aspect, this utility model embodiment provides a three-level positive pressure gradient protective cabin, including a cabin body 100, a disinfection and air supply assembly 200, a first movable door 300, a second movable door 400, a boarding door 141, and a pressure control assembly 500; the cabin body 100 contains an equipment compartment 110, a work compartment 120, a shower compartment 130, and a decontamination compartment 140, the equipment compartment 110 having an air inlet connected to the outside; the disinfection and air supply assembly 200 is installed in the equipment compartment 110, and the disinfection and air supply assembly 200 has an air inlet for connecting to the outside and an air outlet for connecting to the work compartment 120; the first movable door 300 is installed in the shower compartment 110, the first movable door 300, the second movable door 400, the boarding door 141, and the pressure control assembly 500; the first movable door 300 is installed in the shower compartment 110, the second movable door 400, the third movable door 400, the fourth movable door 400, the fifth movable door 400, the sixth movable door 400, the seventh movable door 400, the eleventh movable door 14 ... A first opening is provided on the shower compartment 130 to connect or disconnect the work compartment 120 and the shower compartment 130; a second movable door 400 is installed on the second opening on the decontamination compartment 140 to connect or disconnect the shower compartment 130 and the decontamination compartment 140; a third opening on the decontamination compartment 140 has a boarding door 141, which is located on the outer wall of the container body 100 when the third opening is closed; a pressure control assembly 500 is installed inside the container body 100 to control the pressure inside the work compartment 120 to be greater than the pressure inside the shower compartment 130, and to control the pressure inside the shower compartment 130 to be greater than the pressure inside the decontamination compartment 140.

[0020] During implementation, the disinfection air supply component 200 draws in and processes outside air, and sequentially delivers clean air to the work chamber 120, shower chamber 130, and decontamination chamber 140. By controlling the first movable door 300, the second movable door 400, and the pressure control component 500, the pressure inside the work chamber 120 is adjusted to be greater than the pressure inside the shower chamber 130, and the pressure inside the shower chamber 130 is controlled to be greater than the pressure inside the decontamination chamber 140. Thus, the work chamber 120, shower chamber 130, and decontamination chamber 140 are in a three-level positive pressure gradient state. The air flowing in through the disinfection air supply component 200 flows sequentially through the work chamber 120, shower chamber 130, and decontamination chamber 140, quickly blowing the toxic air carried by personnel and equipment outside the container body 100, effectively preventing untreated outside air from lingering and contaminating the container body 100.

[0021] In this embodiment, the modular shelter 100 contains an equipment compartment 110, a work compartment 120, a shower compartment 130, and a decontamination compartment 140. The equipment compartment 110 has an air inlet that connects to the outside. According to the return flow of personnel and equipment, personnel and equipment enter the decontamination compartment 140 from outside the vehicle for chemical decontamination, then enter the shower compartment 130 for water decontamination, and finally enter the work compartment 120.

[0022] In this embodiment, the disinfection air supply assembly 200 is installed inside the equipment compartment 110. The disinfection air supply assembly 200 has an air inlet for connecting to the outside and an air outlet for connecting to the working compartment 120. Since the equipment compartment 110 is connected to the outside, the disinfection air supply assembly 200 can purify and disinfect the air inside the equipment compartment 110 and then deliver it to the working compartment 120.

[0023] like Figure 2 As shown, in one embodiment, the disinfection air supply assembly 200 includes a primary filter 210, a filter canister 220, a blower 230 and a first air supply duct 240 connected in sequence. The air inlet of the primary filter 210 is used to connect to the outside, and the first air supply duct 240 is connected to the working chamber 120.

[0024] This embodiment also includes an electrically operated louver 111 installed at the air inlet of the equipment compartment 110. The electrically operated louver 111 is used to open and close the air inlet. The electrically operated louver 111 can automatically open and close with the start and stop of the filtration and ventilation assembly. When the filtration and ventilation assembly is started, outside air enters the filtration and ventilation assembly through the electrically operated louver 111. After filtration, the clean air is sent to the working compartment 120. Of course, the electrically operated louver 111 can also be replaced by a structure such as a solenoid valve.

[0025] The air inlet of the primary filter 210 can be connected to the air inlet of the equipment compartment 110 through an air duct.

[0026] In this embodiment, the first movable door 300 and the second movable door 400 are used to connect the work chamber 120 and the shower chamber 130, and the shower chamber 130 and the decontamination chamber 140, respectively, so that personnel and equipment can pass through the work chamber 120, the shower chamber 130 and the decontamination chamber 140 in sequence.

[0027] In this embodiment, the pressure control component 500 is installed inside the container body 100 to control the pressure inside the working chamber 120 to be greater than the pressure inside the shower chamber 130, and to control the pressure inside the shower chamber 130 to be greater than the pressure inside the decontamination chamber 140.

[0028] In one embodiment, the pressure control component 500 includes a first pressure measuring control 510, which has a first detection end for detecting the external air pressure and the air pressure inside the working chamber 120. The first pressure measuring control 510 is electrically connected to the disinfection air supply component 200 and is used to control the operation of the disinfection air supply component 200 according to the external air pressure and the air pressure inside the working chamber 120.

[0029] This embodiment also includes a gas detector 560 installed in the working chamber 120 for detecting the gas quality inside the working chamber 120.

[0030] In one embodiment, the pressure control component 500 includes a second pressure measuring control 520, and the first pressure measuring control 510 has a second detection end for detecting the air pressure in the working chamber 120 and the air pressure in the shower chamber 130, and the first pressure measuring control 510 is capable of adjusting the magnitude of the air pressure difference between the working chamber 120 and the shower chamber 130.

[0031] In one embodiment, the pressure control component 500 includes a third pressure measuring control 530, which has a third detection end for detecting the air pressure inside the shower chamber 130 and the air pressure inside the decontamination chamber 140, and the third pressure measuring control 530 is capable of adjusting the magnitude of the air pressure difference between the shower chamber 130 and the decontamination chamber 140.

[0032] It is understandable that the first pressure measurement control 510, the second pressure measurement control 520 and the third pressure measurement control 530 can be implemented using differential pressure transmitters to detect the pressure difference between two adjacent compartments.

[0033] In this embodiment, the pressure control component 500 further includes a controller 540, which is electrically connected to the disinfection air supply component 200, the first pressure measuring control 510, the second pressure measuring control 520, and the third pressure measuring control 530. The controller 540 is used to receive the air pressure signal from the first detection end and control the operation of the disinfection air supply component 200. The controller 540 is used to receive the air pressure signal from the second detection end and control the operation of the second pressure measuring control 520. The controller 540 is used to receive the air pressure signal from the third detection end and control the operation of the third pressure measuring control 530.

[0034] The controller 540 receives the differential pressure signal detected by the first pressure measuring control 510 and controls the operation of the disinfection air supply assembly 200. By adjusting the disinfection air supply assembly 200, the flow rate of the gas delivered to the working chamber 120 is controlled, thereby controlling the pressure inside the working chamber 120. The controller 540 also receives the differential pressure signal detected by the second pressure measuring control 520 and controls the flow rate of the gas delivered to the shower chamber 130, thereby controlling the pressure inside the shower chamber 130. Finally, the controller 540 receives the differential pressure signal detected by the third pressure measuring control 530 and controls the flow rate of the gas delivered to the decontamination chamber 140, thereby controlling the pressure inside the decontamination chamber 140.

[0035] It is understandable that the pressure in each of the above-mentioned compartments is determined by the difference between the air intake and the air output. It should be noted that the air intake of each compartment is greater than the air output to ensure that each compartment is under positive pressure. At the same time, the second pressure measuring control 520 and the third pressure measuring control 530 can be implemented by using solenoid valves. The air output of the working compartment 120 and the shower compartment 130 can be controlled by controlling the opening and closing degree of the solenoid valves.

[0036] The first movable door 300, the second movable door 400, and the boarding door 141 are connected by a three-level interlock, meaning that only one door can be opened at a time. This ensures that only two adjacent compartments in the work compartment 120, shower compartment 130, and decontamination compartment 140 are connected, preventing all three doors from being open and thus affecting the gradient positive pressure within the three compartments. It is understood that the above-mentioned three-level interlock connection method is a conventional structure that those skilled in the art would recognize, and will not be elaborated upon further.

[0037] To control the pressure inside the decontamination chamber 140, the pressure control component 500 in this embodiment also includes a differential pressure relief valve 550 installed on the decontamination chamber 140. The differential pressure relief valve 550 is used to connect to the outside to stabilize the pressure inside the decontamination chamber 140 and ensure air circulation inside the decontamination chamber 140 by exchanging gas with the outside.

[0038] The modular container body 100 in this embodiment also has a storage compartment 150 for storing equipment.

[0039] On the other hand, this utility model embodiment also provides a fire truck, including the three-level positive pressure gradient protection cabin as described above, and also includes a vehicle body 600, with the cabin body 100 installed on the vehicle body 600, and the disinfection air supply component 200 also having an air supply end connected to the driver's cab of the vehicle body 600.

[0040] The aforementioned fire trucks may be reconnaissance vehicles, which consist of a Class II vehicle chassis and a well-sealed, airtight container body 100.

[0041] In one embodiment, the air supply end of the disinfection air supply assembly 200 is connected to the driver's cab of the vehicle body 600 via a second air supply pipe 250. The assembly also includes a fourth pressure measuring device 610 for detecting the pressure difference between the equipment compartment 110 and the driver's cab of the vehicle body 600. The fourth pressure measuring device 610 can be implemented using a differential pressure transmitter and is connected to a controller 540 to control the pressure inside the driver's cab by controlling a blower.

[0042] Compared with existing technologies: The disinfection air supply component 200 draws in and processes outside air, and delivers clean air sequentially to the work chamber 120, shower chamber 130, and decontamination chamber 140. By controlling the first movable door 300, the second movable door 400, and the pressure control component 500, the pressure inside the work chamber 120 is adjusted to be greater than the pressure inside the shower chamber 130, and the pressure inside the shower chamber 130 is controlled to be greater than the pressure inside the decontamination chamber 140. Thus, the work chamber 120, shower chamber 130, and decontamination chamber 140 are in a three-level positive pressure gradient state. The air flowing in through the disinfection air supply component 200 flows sequentially through the work chamber 120, shower chamber 130, and decontamination chamber 140, quickly blowing the toxic air carried by personnel and equipment outside the container body 100, effectively preventing untreated outside air from lingering and contaminating the container body 100.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
