[0025] Embodiment one: a ventilation device with radiation source shielding effect, as shown in Figure 1 - Figure 4 The utility model discloses a ventilation device with radiation source shielding effect, which comprises a shielding wall 1 and a ventilation duct 2 penetratingly arranged inside and outside the shielding wall 1, an anti-radiation air window 3 is arranged on the surface of one end of the ventilation duct 2 inside the shielding wall 1, an anti-radiation connecting assembly 4 is arranged at the joint of the ventilation duct 2 and the shielding wall 1, the anti-radiation connecting assembly 4 is in contact with the surface of the ventilation duct 2 and the outer surface of the ventilation duct 2 at the same time, and the anti-radiation air window 3 is provided with the anti-radiation connecting assembly 4 at the joint, and the anti-radiation connecting assembly 4 is in contact with the outer surface of the ventilation duct 2 and the surface of the anti-radiation air window 3 at the same time.

[0026] First, under the radiation-proof support of the radiation-proof window 3, the air flowing out of the room is filtered, isolating radiation-containing factors on the outside and preventing them from moving into the ventilation duct 2 on one side. Then, under the curved guidance of the ventilation duct 2 and the radiation-proof isolation of the connection between the ventilation duct 2 and the shielding wall 1 by the radiation-proof connecting component 4, radiation is prevented from moving into the ventilation duct 2 and causing radiation leakage. Furthermore, by also setting the radiation-proof connecting component 4 in the contact area between the radiation-proof window 3 and the ventilation duct 2, and setting the radiation-proof connecting components 4 on both sides to be connected, it is possible to prevent radiation from directly entering the ventilation duct 2 from the outer wall, ensuring the safety and reliability of the ventilation duct 2 for the internal airflow.

[0027] like Figure 1 - Figure 4 As shown, the radiation shielding connection assembly 4 includes a horizontal plate 401 and a vertical plate 402. The horizontal plate 401 and the vertical plate 402 are vertically distributed. The vertical plate 402 is installed on the surface of the shielding wall 1, and the horizontal plate 401 is installed on the surface of the ventilation duct 2.

[0028] The horizontal plate 401 and the vertical plate 402 intersect, and the intersection of the horizontal plate 401 and the vertical plate 402 is concave, with the vertical plate 402 extending into the interior of the horizontal plate 401.

[0029] First, by using lead radiation shielding material to prepare the radiation shielding connection component 4, the reliability of the radiation shielding effect of the radiation shielding connection component 4 is ensured. Furthermore, by setting the connection between the horizontal plate 401 and the vertical plate 402 to a short-distance intersection, a perpendicular intersection surface is formed between the horizontal plate 401 and the vertical plate 402, preventing radiation leakage from the horizontal intersection surface. Thus, under the reflection of radiation from the perpendicular intersection surface, it is impossible for it to leak out due to the horizontal surface, further improving the safety of the air flowing out through the ventilation duct 2.

[0030] like Figure 1 - Figure 4 As shown, Example 2: A ventilation device with radiation source shielding effect, such as...

[0031] Supported by the support frame 301 and guided by the irregular shapes of the side radiation shield 302 and the main radiation shield 303, the radiation reflected in one direction cannot flow out through the side radiation shield 302 and the main radiation shield 303, so that the radiation shield 3 has the effect of preventing radiation from escaping. Thus, under the radiation protection isolation of the radiation shield 3, the safety of the air flowing into the ventilation duct 2 is guaranteed.

[0033] The horizontal part and the vertical part of the L-shaped radiation protection layer 3022 are rounded, and the horizontal part and the vertical part of the L-shaped protective shell 3021 are rounded.

[0034] First, under the limiting support of the L-shaped protective shell 3021, the position of the L-shaped radiation protection layer 3022 is stable during use, and the L-shaped radiation protection layer 3022 is made of lead or other radiation protection materials to improve the radiation protection effect of the side radiation protection member 302 itself, and the inside corner of the side radiation protection member 302 is rounded to reflect the radiation at the corner and effectively prevent the radiation from leaking out.

[0035] As shown in Figure 1 - Figure 4 The main radiation protection member 303 comprises a Z-shaped radiation protection shell 3031 and a Z-shaped radiation protection plate 3032, the Z-shaped radiation protection shell 3031 and the Z-shaped radiation protection plate 3032 are in the same Z shape as the main radiation protection member 303, and the Z-shaped radiation protection plate 3032 is provided with the Z-shaped radiation protection shell 3031 on both sides, and the two Z-shaped radiation protection shells 3031 are provided with the two Z-shaped radiation protection plates 3032, and the corners of the Z-shaped radiation protection shell 3031 and the Z-shaped radiation protection plate 3032 are rounded.

[0036] The Z-shaped radiation protection plate 3032 and the Z-shaped radiation protection shell 3031 are in the shape of Z, which has the effect of multi-layer reflection and isolation based on the distribution of multiple inclined states, ensures the radiation protection strength of the main radiation protection member 303, and the corners of the Z-shaped radiation protection plate 3032 and the Z-shaped radiation protection shell 3031 are rounded to reflect and guide the radiation, prevent the radiation from leaking out through the connection, thereby ensuring the comprehensive radiation protection of the main radiation protection member 303, and the two Z-shaped radiation protection plates 3032 are used in combination to improve the uniformity of the radiation protection on both sides of the main radiation protection member 303, thereby improving the overall radiation protection strength of the radiation protection air window 3 and ensuring the safety of the air flow from the inside to the outside.
