Description

Technical Field

[0001] This utility model relates to the field of emergency rescue technology, specifically to a surface radioactive decontamination cabin device. Background Technology

[0002] Currently, nuclear technology is widely used in the nuclear industry, military, health, and scientific research. Radioactive materials are normally kept in shielded and strictly managed environments. However, in the event of a nuclear accident or attack, radioactive materials can spread, leading to radioactive contamination of people and the environment, causing radiation damage to a certain population group. In emergency rescue, it is necessary to carry out decontamination as early as possible, using decontamination agents and rinsing to remove contaminants from the skin of personnel and promptly stop the continued harm from radioactive materials. Decontamination must be carried out on-site, but radioactive materials exist in the air at the site. Inhalation of these materials can cause internal radiation exposure, resulting in radiation damage. If radioactive materials remain in the decontamination environment, cross-contamination can occur, harming subsequent decontamination personnel. Utility Model Content

[0003] In view of this, the present invention provides a surface radioactive decontamination cabin device to achieve surface decontamination and disinfection of radioactive contaminated personnel, and to control the radioactive damage to personnel caused by radioactive substances in the air during the decontamination and disinfection process.

[0004] This utility model provides a surface radioactive decontamination chamber device, which includes a chamber body, an outer door, and a fresh air module. The chamber body includes a compartment, which includes a changing room, a shower room, a drying room, and a re-examination room connected in sequence. The outer door is movably mounted on the chamber body and is used to close or open the chamber body. The fresh air module is mounted on the chamber body, with its air inlet connected to the outside and its air outlet located in the re-examination room.

[0005] Beneficial effects: Personnel enter the cabin through the outer door, then complete the decontamination process through the changing room, shower room, drying room, and re-examination room. They leave the surface radioactive decontamination cabin from the re-examination room for further testing. The fresh air module continuously supplies clean air to the re-examination room, keeping the changing room, shower room, drying room, and re-examination room in a positive pressure environment. This prevents radioactive air from the external environment from entering the surface radioactive decontamination cabin, helping to avoid radiation damage to personnel from radioactive substances in the air during the decontamination process.

[0006] In one optional embodiment, the surface radioactive decontamination cabin equipment further includes a first exhaust module, which is disposed in the changing room and includes a first exhaust valve and a first pressure sensor. The first pressure sensor is communicatively connected to the first exhaust valve and is used to detect the pressure in the changing room. The outlet of the first exhaust valve is connected to the outside, and the first exhaust module is adapted to control the air pressure.

[0007] Beneficial effects: The first exhaust module can discharge air when the pressure exceeds the set value, thereby maintaining the surrounding air within a suitable pressure range. The first exhaust module discharges air from the changing room, while the fresh air module supplies air to the re-examination room, thus forming a directional airflow with the re-examination room as the starting point and the changing room as the ending point. The airflow direction is opposite to the personnel's movement direction, preventing radioactive materials generated during the personnel decontamination process from flowing into the re-examination room, which helps to improve the cleanliness of the re-examination room. In addition, radioactive materials diffused into the air when personnel move in the changing room and shower room can also be discharged in time through the exhaust module, preventing the accumulation of radioactive materials inside the radioactive decontamination cabin equipment on the body surface.

[0008] In one optional embodiment, the surface radioactive decontamination container further includes an inner door, which is movably disposed on the container body and separates two interconnected compartments.

[0009] Beneficial effects: When no personnel are passing through, the inner hatch is closed, thereby reducing gas exchange between interconnected compartments, preventing gas from flowing in the opposite direction, and reducing the risk of radioactive materials spreading into the air and contaminating the drying room and re-examination room when personnel are active in the changing room and shower room.

[0010] In one optional embodiment, the surface radioactive decontamination chamber further includes a second exhaust module, which is disposed in the re-examination chamber and includes a second exhaust valve and a second pressure sensor. The second pressure sensor is communicatively connected to the second exhaust valve and is used to detect the pressure in the re-examination chamber. The outlet of the second exhaust valve is connected to the dry body chamber, and the second exhaust module is adapted to control the air pressure.

[0011] Beneficial effects: When in use, the exhaust pressure of the second exhaust valve is set higher than that of the first exhaust valve. By adding the second exhaust valve, the pressure gradient between the re-inspection chamber and the drying chamber can be actively controlled, which helps to further ensure the directional flow of gas between the re-inspection chamber and the drying chamber.

[0012] In one optional embodiment, the inner door between the shower room and the changing room, and the inner door between the shower room and the drying room are provided with a first electronic lock, wherein when any one of the first electronic locks is in the unlocked state, the other first electronic locks are in the locked state.

[0013] Beneficial effects: By setting up a first electronic lock, the shower room can act as a buffer, preventing the changing room and the drying room from being connected, thereby reducing the risk of radioactive material from the changing room contaminating the drying room.

[0014] In one alternative embodiment, the compartment includes a plurality of shower rooms, each of which is arranged independently side by side.

[0015] Beneficial effects: By setting up multiple shower rooms, each for independent use by a single person, cross-contamination between personnel can be avoided, and the negative impact of the first electric lock on the use of the shower room can also be reduced.

[0016] In one optional embodiment, the shower room is provided with a full-body shower head and a partial shower head, wherein the rated water pressure of the partial shower head is lower than the rated water pressure of the full-body shower head.

[0017] Beneficial effects: Setting up full-body and localized shower heads allows for a more comprehensive and thorough cleaning of the body surface. The localized shower heads have relatively lower water pressure, which can prevent water flow from impacting and damaging the cornea, mucous membranes, or other vulnerable parts of the body.

[0018] In one alternative embodiment, the compartment further includes a buffer room disposed between the external environment and the changing room, with an outer hatch connecting the buffer room and the external environment.

[0019] Beneficial effects: When entering the cabin, personnel first enter the buffer room, then close the outer hatch, and then open the inner hatch to enter the changing room. Setting up a buffer room can reduce the amount of radioactive material brought in by personnel and reduce the degree of contamination in the changing room.

[0020] In one optional embodiment, the fresh air module includes a fresh air unit, an air intake pipe, and a filter. The fresh air unit is located in the changing room, the air outlet of the fresh air unit is located in the re-examination room, the air inlet of the fresh air unit is connected to one end of the air intake pipe, the other end of the air intake pipe is connected to the outside, and the filter is located inside the air intake pipe.

[0021] Beneficial effects: The fresh air unit continuously pumps air into the re-inspection room, and the filter screen can filter impurities in the air, ensuring the normal operation of the fresh air unit.

[0022] In one optional embodiment, the surface radioactive decontamination container further includes a soiled clothing collection cabinet, which is located in the changing room; the soiled clothing collection cabinet abuts against the outer wall of the container, and the outer wall is provided with a door for retrieving clothes corresponding to the soiled clothing collection cabinet.

[0023] Beneficial effects: Clothes contaminated with radioactive materials can be stored in a centralized collection cabinet for easy collection and disposal. Staff can retrieve clothes directly from the cabinet through the retrieval door without entering the surface radioactive decontamination chamber, thus improving the ease of use of the equipment.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0031] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0033] In the event of the spread or contamination of radioactive materials or substances, personnel should be decontaminated on-site as soon as possible to promptly stop the continued harm from radioactive materials.

[0034] In related technologies, radioactive decontamination chambers are used for decontamination work. However, radioactive substances exist in the environment. These radioactive substances can enter the radioactive decontamination chambers through gas exchange, and radioactive substances on the body surface can also diffuse into the environment during the decontamination process, thus contaminating the inside of the radioactive decontamination chambers and harming subsequent decontamination personnel.

[0035] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0036] According to an embodiment of this utility model, in one aspect, a surface radioactive decontamination cabin device is provided, referring to... Figure 1 The surface radioactive decontamination cabin equipment includes a cabin body, an outer door 1021, and a fresh air module 103. The cabin body includes a compartment, which includes a changing room 1012, a shower room 1013, a drying room 1014, and a re-examination room 1015 connected in sequence. The outer door 1021 is movably installed on the cabin body and is used to close or open the cabin body. The fresh air module 103 is installed on the cabin body, and the air outlet of the fresh air module 103 is located in the re-examination room 1015.

[0037] During decontamination, personnel open the outer hatch 1021 and enter the cabin. First, they change their contaminated clothing in changing room 1012. Next, they enter the shower room 1013 to wash away surface contaminants. Then, they proceed to the drying room 1014 to dry their bodies. Finally, they enter the re-inspection room 1015 to check the decontamination status of their bodies. Those who pass the surface decontamination test leave the decontamination cabin from the re-inspection room 1015 for the next stage of testing. Those who fail the surface decontamination test return to the shower room 1013 for a second decontamination.

[0038] During this process, the fresh air module 103 can continuously filter the outside air and introduce it into the re-inspection chamber 1015, thereby creating a positive pressure environment in the re-inspection chamber 1015 and other chambers connected to the re-inspection chamber 1015 inside the cabin.

[0039] This invention continuously supplies clean air through the fresh air module 103, keeping the changing room 1012, shower room 1013, drying room 1014, and re-examination room 1015 in a positive pressure environment. This prevents air containing radioactive substances from the external environment from entering the body surface radioactive decontamination chamber through the buffer room 1011. Therefore, the body surface radioactive decontamination chamber helps to prevent radioactive substances in the air from causing radiation damage to personnel during the decontamination process.

[0040] Understandably, the hull is composed of bulkheads, which can be further divided into inner bulkheads and outer bulkheads. The outer bulkheads surround and form the outer outline of the hull, while the inner bulkheads further divide the interior of the hull into various compartments.

[0041] The main body of the fresh air module 103 can be installed inside or outside the surface radioactive decontamination cabin equipment, for example, referring to Figure 1 and Figure 2 In some embodiments, the fresh air module 103 includes a fresh air unit 1031, an air intake pipe 1032, and a filter 1034. The fresh air unit 1031 is located in the changing room 1012, and its air outlet is located in the re-inspection room 1015. The air inlet of the fresh air unit 1031 is connected to one end of the air intake pipe 1032, and the other end of the air intake pipe 1032 is connected to the outside. The filter 1034 is located inside the air intake pipe 1032. The fresh air unit 1031 continuously pumps air into the re-inspection room 1015, and the filter 1034 filters impurities in the air, ensuring the normal operation of the fresh air unit 1031.

[0042] Furthermore, referring to Figure 2 In some embodiments, the fresh air module 103 also includes louvers 1035 and a protective net 1036. The louvers 1035 and the protective net 1036 are disposed at the inlet of the air intake pipe 1032, which play a preliminary filtering role and improve the operational reliability of the fresh air module 103.

[0043] In some embodiments, the surface radioactive decontamination cabin equipment further includes a first exhaust module, which is disposed in the changing room 1012 and includes a first exhaust valve 1041 and a first pressure sensor (not shown in the figure). The first pressure sensor is communicatively connected to the first exhaust valve 1041 and is used to detect the pressure of the changing room 1012. The outlet of the first exhaust valve 1041 is connected to the outside, and the first exhaust module is adapted to control the air pressure.

[0044] The first exhaust module discharges air from the changing room 1012, while the fresh air module 103 supplies air to the re-inspection room 1015, thus forming a directional airflow with the re-inspection room 1015 as the starting point and the changing room 1012 as the ending point. The airflow direction is opposite to the personnel's movement direction, which prevents radioactive materials generated during the personnel decontamination process from flowing into the re-inspection room 1015 and helps to improve the cleanliness of the re-inspection room 1015.

[0045] In addition, radioactive materials that diffuse into the air when personnel are active in changing room 1012 and shower room 1013 (e.g., putting on and taking off clothes in changing room 1012 and washing off contaminants in shower room 1013) can be discharged in a timely manner through the exhaust module, preventing the accumulation of radioactive materials inside the radioactive decontamination container equipment on the body surface.

[0046] In some embodiments, in order to facilitate the re-disinfection of personnel who fail the inspection and to ensure one-way movement of personnel, the re-inspection room 1015 can be connected to the changing room 1012, and personnel can directly enter the changing room 1012 from the re-inspection room 1015.

[0047] It is understandable that exhaust is achieved by adjusting the opening of the first exhaust valve 1041. Adjusting the opening can be either simply controlling the first exhaust valve 1041 to switch between open and closed states, or it can be adjusting the opening cross-sectional area of ​​the first exhaust valve 1041. The first pressure sensor can be a differential pressure transmitter or other conventional pressure sensor. The first exhaust valve 1041 can be a butterfly valve, needle valve, or other types of valve. For specific model selection, please refer to relevant existing technologies.

[0048] To further ensure directional gas flow, in some embodiments, the surface radioactive decontamination cabin equipment also includes an inner door 1022, which is movably mounted on the cabin body and separates two interconnected compartments. When no personnel are passing through, the inner door 1022 is closed, thereby reducing gas exchange between the interconnected compartments, preventing gas from flowing against a predetermined direction, and reducing the risk of radioactive material contaminating the drying room 1014 and re-examination room 1015 when personnel are active in the changing room 1012 and shower room 1013.

[0049] In some embodiments, the surface radioactive decontamination cabin equipment further includes a second exhaust module, which is disposed in the re-examination chamber 1015 and includes a second exhaust valve 1042 and a second pressure sensor. The second pressure sensor is communicatively connected to the second exhaust valve 1042 and is used to detect the pressure in the re-examination chamber 1015. The outlet of the second exhaust valve 1042 is connected to the dry body chamber 1014, and the second exhaust module is adapted to control the air pressure.

[0050] The second exhaust module can introduce a second level of pressure control for the surface radioactive decontamination chamber equipment. When in use, the exhaust pressure of the second exhaust valve 1042 is set to be higher than that of the first exhaust valve 1041. By increasing the second exhaust valve 1042, the pressure gradient between the re-examination chamber 1015 and the drying chamber 1014 can be actively controlled, which helps to further ensure the directional flow of gas between the re-examination chamber 1015 and the drying chamber 1014.

[0051] In some embodiments, the inner door 1022 between the shower room 1013 and the changing room 1012 and the inner door 1022 between the shower room 1013 and the drying room 1014 are provided with first electronic locks. When any one of the first electronic locks is in the unlocked state, the other first electronic locks are in the locked state.

[0052] On the one hand, the present invention uses the first electric lock to make the shower room 1013 act as a buffer, avoiding the situation where the changing room 1012 and the drying room 1014 are directly connected, further ensuring the unidirectional flow of air between the changing room 1012, the shower room 1013 and the drying room 1014, and preventing other compartments outside the changing room 1012 from being contaminated.

[0053] On the other hand, the buffering effect of the shower room 1013 eliminates the need for an exhaust module to be installed between the changing room 1012 and the shower room 1013, and between the shower room 1013 and the drying room 1014 for active pressure control. This reduces the number of pressure gradient stages, which helps the first exhaust valve 1041 to use a higher exhaust pressure and reduces the risk of outside air backflowing and contaminating the changing room 1012 through the first exhaust valve 1041.

[0054] In some embodiments, the compartment includes multiple shower rooms 1013, each shower room 1013 being arranged side by side and independently. By providing multiple shower rooms 1013, each shower room 1013 is used independently by a single person, which helps to avoid cross-contamination between personnel and also reduces the negative impact of the first electric lock on the use of the shower room 1013.

[0055] In some embodiments, the shower room 1013 is equipped with a full-body shower head and a local shower head, wherein the rated water pressure of the local shower head is lower than that of the full-body shower head. The combination of full-body and local shower heads allows for a more comprehensive and thorough cleaning of the body surface. The relatively lower water pressure of the local shower head helps to prevent water flow from damaging the cornea, mucous membranes, or other vulnerable areas of the body.

[0056] In some embodiments, the compartment further includes a buffer chamber 1011, which is disposed between the external environment and the changing room 1012. An outer hatch 1021 is provided between the buffer chamber 1011 and the external environment. When entering the compartment, personnel first enter the buffer chamber 1011, then close the outer hatch 1021, and then open the inner hatch 1022 to enter the changing room 1012. The buffer chamber 1011 can reduce the amount of radioactive material brought in by personnel upon entry, thereby reducing the level of contamination in the changing room 1012.

[0057] It is understood that the buffer chamber 1011 is used to prevent uncontrolled intrusion of external gases into the changing room 1012 during personnel entry. Therefore, during decontamination and cleaning, the inner hatch 1022 and outer hatch 1021 on both sides of the buffer chamber 1011 cannot be opened simultaneously. Optionally, in some embodiments, a second electronic lock is provided on the outer hatch 1021 between the buffer chamber 1011 and the external environment, and on the inner hatch 1022 between the buffer chamber 1011 and the changing room 1012. When any one of the second electronic locks is in the unlocked state, the other second electronic locks are in the locked state.

[0058] By introducing a second electronic lock to control the inner hatch 1022 and outer hatch 1021 on both sides of the buffer chamber 1011, accidents can be avoided when personnel operate manually.

[0059] In some embodiments, the re-examination chamber 1015 includes a whole-body contamination detector that uses plastic scintillation detection technology to detect contaminants carried by personnel.

[0060] In some embodiments, the drying chamber 1014 is equipped with a drying machine that provides hot air to remove liquid water from the body surface, prevent the injured person from catching a cold, and ensure the normal operation of the whole-body contamination detector used for re-examination.

[0061] In some embodiments, the surface radioactive decontamination container also includes a soiled clothing collection cabinet 105, which is located inside the changing room 1012. Clothing contaminated with radioactive materials removed by personnel can be stored uniformly in the soiled clothing collection cabinet 105 for centralized collection and disposal.

[0062] Optionally, in some embodiments, the soiled laundry collection cabinet 105 abuts against the outer wall of the cabin, and the outer wall is provided with a retrieval door 1023 corresponding to the soiled laundry collection cabinet 105. Staff can directly retrieve clothing from the soiled laundry collection cabinet 105 through the retrieval door 1023 from the outside without having to enter the body surface radioactive decontamination cabin equipment, thus improving the ease of use of the body surface radioactive decontamination cabin equipment.

[0063] The surface radioactive decontamination container equipment provided by this utility model can be installed on a transport device, thus enabling flexible and efficient deployment on site.

[0064] It is understandable that the transport device can be a truck, train, ship, or other device suitable for carrying and transporting the surface radioactive decontamination container equipment, so as to facilitate the efficient and timely transport of the surface radioactive decontamination container equipment to the accident site for decontamination operations.

[0065] Taking the use of an emergency rescue vessel as a transport device as an example, the external dimensions of the surface radioactive decontamination cabin equipment can be designed to be 6058mm*3000mm*2591mm. The surface radioactive decontamination cabin equipment is connected to the power and fresh water interfaces of the vessel through its own cable and soft water pipe. The cabin door is sealed with rubber strips, and the decontamination wastewater and medical waste liquid generated during the operation are treated separately.

[0066] In operation, the injured are transported to the deck of the emergency rescue vessel, where rapid triage is conducted to categorize them into those requiring emergency treatment and those with general injuries. For general injuries, a preliminary screening for surface radioactive contamination is performed. Those with surface radioactive contamination are then placed in a decontamination chamber for decontamination followed by dose testing. Those without surface radioactive contamination undergo dose testing directly. Those requiring emergency treatment receive immediate medical intervention.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
