Description

Technical Field

[0002] In many specific work and research environments, such as CT and DR rooms in medical imaging departments, clean rooms for electronic chip manufacturing, and areas surrounding nuclear reactors, the presence of radiation poses a potential threat to personnel health and the normal operation of equipment.

This makes them unable to meet the comprehensive protection needs in complex environments. Moreover, traditional shielding doors have poor sealing performance, allowing radiation to easily leak from gaps in the door and frame, which greatly reduces the protective effect and is detrimental to improving the safety of equipment use.

[0030] A modular door frame, comprising an outer frame 200, an inner frame 230, and a door opening covering plate 220 that is inserted and installed between the outer frame 200 and the inner frame 230;

[0031] The door body is rotatably mounted on the outer wall of the outer frame 200. The door body includes a core 300, an outer shielding plate 310 and an inner shielding plate 320. Metal shielding strips 330 and sealing rings 340 are installed around the outer wall of the outer shielding plate 310.

[0032] The specific application scenario of this embodiment is as follows: By setting up a combined door frame and door body to form a shielded door structure, and by setting an outer shielding plate 310 and an inner shielding plate 320 in the door body to intercept and shield various radiation rays, the safety of equipment use is improved. At the same time, at the connection between the door stop 222 and the outer shielding plate 310, a metal shielding strip 330 and a sealing ring 340 are installed to seal and intercept airflow and radiation rays, thereby preventing the leakage of radioactive materials between indoors and outdoors and improving the safety of equipment use.

[0033] Example 2: Figure 4 and Figure 5 The outer frame 200 is fixedly installed on the outer wall of the door opening 110 inside the wall 100, and the inner frame 230 is fixedly installed on the inner wall of the door opening 110. Slots 210 are opened on the inner walls of both the outer frame 200 and the inner frame 230. The door opening covering plate 220 is connected to the front and rear slots 210 by interlocking. The door opening covering plate 220 is fitted onto the outer wall of the door opening 110. Insert plates 221 are fixedly installed on the front and rear outer walls of the door opening covering plate 220. The outer wall of the insert plate 221 is connected to the slot 210 by interlocking. A door stop 222 is fixedly installed on the outer wall of the door opening covering plate 220. The connection between the door stop 222 and the outer wall of the outer shielding plate 310 is sealed by a sealing ring 340.

[0034] The specific application scenario of this embodiment is as follows: by setting the hole covering plate 220, the outer frame 200 and the inner frame 230 together, it is used to facilitate the wrapping of the inner wall of the door opening 110, and at the same time facilitates the installation of the door and auxiliary structures.

[0035] Example 3: As Figure 1 and Figure 6 An outer shielding plate 310 is fixedly installed on the front outer wall of the core 300, and an inner shielding plate 320 is fixedly installed on the rear outer wall of the core 300. The surfaces of the outer shielding plate 310 and the inner shielding plate 320 are uniformly sprayed with waterproof paint. The outer walls of the outer shielding plate 310 and the inner shielding plate 320 are provided with decorative surfaces. An annular groove 311 is opened on the outer wall around the outer perimeter of the outer shielding plate 310. A metal shielding strip 330 is fixedly installed on the inner wall of the annular groove 311. A sealing ring 340 is fixedly installed on the outer wall of the metal shielding strip 330. A magnetic lock 350 is installed on the inner wall of the door. The magnetic lock 350 is used to lock the door body and the door opening covering plate 220. An access control controller 270 is fixedly installed on the outer wall of the outer frame 200.

[0036] The specific application scenario of this embodiment is as follows: By setting an outer shielding plate 310 and an inner shielding plate 320, a double radiation shielding effect is achieved on the door. The outer shielding plate 310 is made of lead plate, a metal with high density and excellent ability to absorb X-rays and gamma rays. In the field of radiation protection, lead plates are a commonly used shielding material, effectively blocking most X-rays and gamma rays, thereby reducing the harm of radiation to the surrounding environment and personnel. The inner shielding plate 320 is made of boron-containing polyethylene, a composite material formed by uniformly dispersing boron in a polyethylene matrix. Boron has a strong absorption capacity for neutrons, therefore, boron-containing polyethylene has a good shielding effect against neutron radiation. Combined with the lead plate of the first shielding layer, comprehensive protection against various types of radiation (such as X-rays, gamma rays, and neutron radiation) can be achieved. Waterproof paint is then applied... The outer shielding plate 310 and the inner shielding plate 320 serve to block water and improve corrosion resistance. The decorative surface enhances aesthetics. The annular groove 311 is used to fix the metal shielding strip 330 and the sealing ring 340, allowing them to be embedded and improving the door's appearance. The magnetic lock 350 controls the locking between the door and the door opening covering plate 220. The access control controller 270 allows operators to unlock the magnetic lock 350 from the outside using a password.

The rotating shaft 240 is driven to rotate by a stepper motor 260, thereby driving the door to rotate and adjust, which is used to control the opening and closing of the door.

[0039] The working principle of this utility model is as follows: When used by those skilled in the art, the outer frame 200, the door opening covering plate 220, and the inner frame 230 are sequentially fixedly installed on the outer wall of the door opening 110.
