Description

Technical Field

[0001] This invention belongs to the field of radiation protection equipment, specifically relating to a high-protection, low-gravity external radiation protective suit. Background Technology

[0002] External radiation protective clothing is an important piece of radiation protection equipment used to ensure the safety and health of personnel in radiation environments. It directly reduces the radiation dose received by personnel through the shielding material within the clothing. However, due to the significant weight of the shielding material, and considering the balance between the burden on the human body, operational efficiency, and protective effectiveness, the weight of external radiation protective clothing is usually controlled to within 10 kg. This results in the protective clothing's shielding capability against gamma rays being approximately limited to 1–1.5 mmPb. 60 Co source).

[0003] As the nation and industry place increasing emphasis on the occupational health of nuclear facility workers, new requirements have been placed on the protective capabilities of external radiation protection equipment. For example, radiation protection personnel at nuclear facilities are considering increasing the lead equivalent of their external radiation protection clothing to 3 mmPb or higher. 60 (Co source). Currently, the only effective way to improve the radiation protection capability of external radiation protective clothing is to further increase the weight of the shielding material. However, excessive weight places a great burden on personnel, causing fatigue damage to muscle groups and joints, making it impossible for personnel to wear and work effectively. Therefore, it is urgent to introduce new technologies to truly create a new type of radiation protection equipment that is both lightweight and effective.

[0004] As an effective structural solution to the contradiction between heavy loads and human body load, the design of combining exoskeletons with external radiation protection clothing has received initial attention in the field of interventional radiology and other radiation medicine. It is mainly used to support and assist medical personnel in wearing external radiation protection clothing (lead aprons), thereby reducing the physical burden on personnel. For example, patent CN202410872836.4 discloses a wearable radiation protection device with exoskeleton support, including a main frame for support, a limiting head frame, a leaded glass cover, a neck lead curtain, a cooling fan, supporting leg frames, a lead protective suit, and a sterile gown. Through the action of the supporting leg frames and their hydraulic support rods, it ensures that each medical staff member receives personalized strength assistance. Patent CN202120776152.6 discloses a radiation-proof lead apron with mechanical exoskeleton-assisted load-bearing, including a frame and a lead apron body. The lead apron body is fitted onto the frame, which has the advantages of reducing the burden of the lead apron on the human body, facilitating walking and side turning after wearing, and having an adjustable frame size.

[0005] Due to limitations in human tolerance, the lead equivalent of traditional external radiation protective clothing currently used at nuclear facilities can only reach 1–1.5 mmPb. 60The protection effect is limited when working in a high dose rate place. The existing exoskeleton assisted external exposure protective clothing is mainly used in the field of medical radiation, and the lead equivalent of the medical external exposure protective clothing is generally not more than 0.5mmPb 60 Therefore, the existing medical exoskeleton has general load-bearing performance, and the protective clothing and the exoskeleton are directly mounted without other fixing and matching structures, so that the stability and adaptability are poor, and the personnel protection and operation requirements in the nuclear facility cannot be effectively met.

[0039] As shown in Figure 6 and Figure 7 The wearing process of the high-protection low-weight external irradiation protective clothing provided by the embodiment of the application is as follows:

[0040] S1, preliminary wearing of the exoskeleton module is performed, the shoulder straps, waistbands, shoelaces and exoskeleton leg binding turnbuckles are adjusted to appropriate positions, and the preliminary wearing and fixing between the exoskeleton module and the personnel is completed.

[0041] S2, the length of each support rod of the exoskeleton module is adjusted by the back plate 2 and the leg component adjustment buckle of the exoskeleton module in combination with the body size of the wearer, to ensure that the positions of the joints of the exoskeleton module and the positions of the joints of the human body are in a corresponding state, and at the same time, to ensure that the shoulder support 1 of the exoskeleton module and the shoulder of the personnel maintain a height gap of 5-8cm, to avoid the deformation of the shoulder support 1 under the gravity of the protective clothing module and the compression of the human shoulder, thereby affecting the weight reduction effect.

[0042] S3, wearing of the base layer 10 of the protective clothing module is performed, the back piece of the base layer 10 is first adjusted to just cover the position of the back of the human body, then the shoulder straps 12 and the exoskeleton shoulder support are adhered by magic tape, and then the front piece of the base layer 10 is adjusted to an appropriate position, the magic tape adhesion between the back piece shoulder straps 12 and the external waistband 13 and the corresponding position of the front piece is completed, thereby completing the wearing of the base layer 10.
