Description

Technical Field

[0001] This patent relates to the technical field of rapid repair of equipment and facilities in radioactive hot rooms, and specifically to an inflatable air tent suitable for emergency repairs in radioactive environments. Background Art

[0002] In the production and testing of nuclear fuel, nuclear reactor operation, nuclear facility decommissioning, nuclear accident emergency and radiation processing, in order to prevent the risk of environmental pollution caused by aerosol overflow during emergency repairs in radioactive environments, building a protective gas tent is a common means. However, the existing protective gas tents are supported by metal frames, which have problems such as long construction time, high requirements for the construction environment, and difficulty in construction operation. They are easy to break and have poor sealing, which reduces the efficiency of emergency repair operations. At the same time, ordinary gas tents are mostly used for rescue and travel, and are not designed for emergency repairs in radioactive environments. The concepts of temperature zones and hot zones are not considered in the partitions inside the gas tent. There are high requirements for the sealing of the air column, but there are no sealing requirements for the inside of the gas tent. For this reason, an inflatable sealed isolation gas tent is designed with a rigorous use process to ensure the sealing isolation of the radioactive atmosphere while preventing the occurrence of cross contamination, thereby solving the existing problems. Summary of the invention

[0003] The purpose of the present invention is to provide an inflatable air tent suitable for emergency repairs in a radioactive environment, so as to improve the working efficiency of emergency repairs.

[0004] The technical scheme of the present invention is as follows: an inflatable air tent suitable for emergency repairs in a radioactive environment, comprising a tent body, the tent body comprising an air column, a bottom pad, side walls and a canopy; the interior of the tent body comprises a temperature zone and a hot zone, wherein the temperature zone corresponds to an area with low radioactivity, and the hot zone corresponds to an area with high radioactivity; there is a personnel passage A on the hot zone; there is a personnel passage B between the temperature zone and the hot zone; there is a material passage at a position corresponding to the canopy and the hot zone; there is a passage C at a position corresponding to the bottom pad and the hot zone; an air clothing air supply passage is arranged on the side wall of the hot zone of the air tent, and an air tent internal air supply passage is arranged on the side wall of the temperature zone; and an air column air supply device is also included to supply air to the air column.

[0005] The air columns, bottom pads, side walls and roof are connected to each other by heat welding.

[0006] The material of the air column is PV double-sided coated airtight cloth, the material of the tent base and top canopy is PVC, and the side wall is made of transparent PVC.

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

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

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

[0010] S1: transport the compressed inflatable air tent suitable for emergency repairs in radioactive environments to the docking channel of the emergency site;

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

[0012] S3: After inflation is completed, channel C is connected with the channel of the emergency maintenance area. The personnel wearing compressed protective air clothing open personnel channel A to enter the warm zone, close personnel channel A, open personnel channel B to enter the hot zone, and close personnel channel B. After the personnel inflate the protective air clothing through the air clothing air supply channel, they open channel C at the bottom pad 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 parts need to be transferred in or out, external assistants open the material passage on the top of the air tent to transfer the parts in or out.

[0014] New spare parts or repaired parts are transferred in or out by bagging with the help of lifting equipment.

[0015] In S3, after completing the work, the personnel returns to the hot zone, closes channel C, opens personnel channel B, enters the warm zone, closes personnel channel B, takes off the protective gas suit and stays in the warm zone, opens personnel channel A to leave, and closes personnel channel A.

[0016] The significant effect of the present invention is that based on the existing personnel protection measures during emergency repair work in a radioactive environment, an inflatable sealed isolation air tent is designed, which uses air instead of bones to reduce the weight of the air tent, facilitate use, and overcome the disadvantage that the air tent is difficult to build when it has a metal frame.

[0017] An inflatable air tent is designed to solve the risk of radioactive atmosphere spillage during emergency repair work. BRIEF DESCRIPTION OF THE DRAWINGS
