Description

Technical Field

[0001] This patent relates to the field of rapid repair technology for equipment and facilities in radioactive thermal chambers, specifically to an inflatable tent suitable for emergency repairs in radioactive environments. Background Technology

[0002] In nuclear fuel production, nuclear reactor operation, nuclear facility decommissioning, nuclear accident emergency response, and radiation processing, constructing protective gas tents is a common method to prevent environmental pollution from aerosol spills during emergency repairs in radioactive environments. However, existing protective gas tents use metal frames for support, which suffer from problems such as long construction time, stringent environmental requirements, difficult construction operations, susceptibility to damage, and poor sealing, reducing the efficiency of emergency repairs. Furthermore, most ordinary gas tents are used for rescue and disaster relief and travel, and are not designed for emergency repairs in radioactive environments. The internal zoning of the gas tent does not consider the concepts of warm and hot zones, and while there are high requirements for the sealing of the gas column, there are no requirements for the sealing of the interior of the tent. Therefore, this paper proposes an inflatable, sealed isolation gas tent with a rigorous operating procedure to ensure the sealed isolation of the radioactive atmosphere while preventing cross-contamination, thus solving the existing problems. Summary of the Invention

[0003] The purpose of this invention is to provide an inflatable air tent suitable for emergency repairs in radioactive environments, thereby improving the efficiency of emergency repair operations.

[0004] The technical solution of the present invention is as follows: An inflatable air tent suitable for emergency repairs in a radioactive environment includes a tent body, which includes an air column, a base, side walls, and a canopy; the interior of the tent body includes a warm zone and a hot zone, wherein the warm zone corresponds to the area with low radioactivity, and the hot zone corresponds to the area with high radioactivity; there is a personnel passage A on the hot zone; there is a personnel passage B between the warm zone and the hot zone; there is a material passage at the position of the canopy corresponding to the hot zone; there is a passage C at the position of the base corresponding to the hot zone; an air clothing supply channel is provided on the side wall of the hot zone of the air tent, and an internal air supply channel of the air tent is provided on the side wall of the warm zone; it also includes an air column supply device for supplying air to the air column.

[0005] The air column, base pad, side walls and canopy are connected in pairs by heat sealing welding.

[0006] The air column is made of PV double-coated airtight fabric, the tent floor and roof are made of PVC, and the side walls are made of transparent PVC.

[0007] Personnel passage A, personnel passage B, passage C, and material passage are sealed to the tent body via a straight zipper.

[0008] Personnel passage A and personnel passage B are arranged diagonally.

[0009] A method for using an inflatable air tent suitable for emergency repairs in a radioactive environment includes the following steps:

[0010] S1: Transfer the compressed inflatable tent suitable for emergency repairs in radioactive environments to the docking passage at the emergency site.

[0011] S2: Open the air supply channel and air column supply device to inflate the air column and the warm and hot zones;

[0012] S3: After inflation is complete, connect passage C with the passage in the emergency maintenance area. Personnel wearing compressed protective air suits open personnel passage A to enter the warm zone, close personnel passage A, open personnel passage B to enter the hot zone, and close personnel passage B. After personnel inflate the protective air suits through the air suit supply passage, open passage C at the bottom of the air tent and enter the emergency area to carry out operations.

[0013] In S3, when personnel enter the emergency area to carry out operations, if it is necessary to transfer parts in or out, external auxiliary personnel will open the material channel at the top of the air tent to transfer the parts in or out.

[0014] New spare parts or parts to be repaired are transferred in or out using a bagging method with the aid of hoisting equipment.

[0015] In step S3, after completing the work, the personnel return to the hot zone, close passage C, open personnel passage B, enter the warm zone, close personnel passage B, remove the protective air suit and leave it in the warm zone, open personnel passage A to leave, and close personnel passage A.

[0016] The significant advantage of this invention is that, based on existing personnel protection measures for emergency repair operations in radioactive environments, an inflatable sealed isolation tent is designed, using air instead of a frame to reduce the weight of the tent, facilitate its use, and overcome the disadvantage of difficulty in setting up an inflatable tent with a metal frame.

[0017] Design an inflatable air tent to solve the problem of the risk of radioactive atmosphere leakage during emergency repair work. Attached Figure Description

[0026] The present patent will now be further described with reference to the accompanying drawings;

[0027] The inflatable tent designed in this invention patent is suitable for sealing and isolating aerosols during emergency repairs in radioactive environments, and includes a tent body and a passage module.

[0028] The tent body comprises air columns 12 for support, a base pad 14, side walls 13, and a canopy 11, all connected in pairs by heat-sealing welding. The air columns 12 are made of PV double-coated airtight fabric, inflated externally to support the tent body, and their structure can be optimized according to the setup environment. The base pad 14 and canopy 11 are made of PVC material. The base pad 14 has increased surface roughness to prevent slipping during use, while the side walls 13 are made of transparent PVC material to facilitate communication between people inside and outside the tent. The tent body is designed with two spaces: the first space, isolated from areas with lower radioactive contamination via a passage module, is called the "temperature zone" 15; the second space, isolated from areas with higher radioactive contamination via a passage module, is called the "heat zone" 16.

[0029] The access module includes personnel access ( Figure 2 ) and material passage ( Figure 3Personnel passage A21 connects temperature zone 15 with areas of lower radioactive contamination, personnel passage B22 connects temperature zone 15 with hot zone 16, and personnel passage C24 connects hot zone 16 with areas of higher radioactivity. Personnel passages A21 and B22 are arranged diagonally to reduce the probability of atmosphere penetration. The personnel passages are connected to the tent body by heat welding. The sealing function of the personnel passages is accomplished by a straight zipper 23. When personnel pass through, they open the zipper and close it quickly after passing through.

[0030] The material passage includes the passage to the hot zone 16, which is shared with the personnel passage C24. The material passage between the hot zone 16 and the low-radioactivity area outside the air tent is located on the canopy 11 and is connected by heat welding. The sealing function is accomplished by a straight zipper 23. In addition, an air clothing air supply passage 32 is provided on the side wall 13 of the hot zone 16, and an air tent internal air supply passage 33 is provided on the side wall 13 of the temperature zone 15. It can be quickly connected to the external air supply device for air supply.

[0031] In an emergency, personnel transport the compressed inflatable air tent to the emergency access point, open the air supply channel 33 and the air column supply device, and inflate the air column 12, temperature zone 15, and hot zone 16. After inflation, connect the personnel access point C24 of the air tent to the access point of the emergency maintenance area. Personnel wearing protective air suits open personnel access point A21 to enter the temperature zone 15 of the air tent, close personnel access point A21, open personnel access point B22 to enter the hot zone 16 of the air tent, and close personnel access point B22. Personnel open personnel access point C24 at the bottom pad 14 of the air tent to enter the emergency area to carry out operations. If it is necessary to transfer new spare parts or repaired components in or out, external auxiliary personnel open the material channel 31 at the top of the air tent and transfer the new spare parts or repaired components in or out using a hoisting device with sealed bags, ensuring that the atmosphere is sealed and isolated during the transfer of work areas.

[0032] In this invention, the structural design is reasonable, and while achieving the required functions, it solves the problems of difficulty in constructing existing protective air tents and the leakage of radioactive atmosphere during use.
