Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering, in particular to a radiation protection structure used for a pipeline to pass through a wall of a medical accelerator room. Background Art
[0002] Patients with tumors and other diseases often use radiotherapy, chemotherapy and other treatment methods. Such treatments are usually performed in the accelerator room or gamma knife room of the hospital's radiology department. When in use, medical equipment such as accelerators and gamma knives will produce serious radiation, which has a greater impact on healthy people.
[0003] To prevent accelerators, gamma knives, etc. from radiating outward, the walls, ceilings and floors of accelerator rooms and gamma knife rooms are made of very thick reinforced concrete structures, some of which are even thicker than 1.0m. Holes cannot be opened after the reinforced concrete structure is poured. Therefore, measures need to be taken to prevent the mechanical, electrical and air-conditioning pipelines from passing through the walls. Utility Model Content
[0004] The utility model provides a radiation protection structure for pipelines passing through the wall of a medical accelerator room. By pre-buried steel pipe sleeves in the wall of the medical accelerator room during civil construction, the problem of difficulty in arranging pipelines in the later stage due to the thick wall of the medical accelerator room is effectively solved; in addition, the radiation protection effect is greatly improved by setting the steel pipe sleeves and the pipeline structure. The specific scheme is as follows:
[0005] A radiation protection structure for a pipeline passing through the wall of a medical accelerator room, the medical accelerator room includes a floor, a ceiling, a suspended ceiling below the ceiling, and a wall, a steel pipe sleeve is embedded in the wall, the steel pipe sleeve is arranged through the wall, and has two openings, including a first opening end and a second opening end, the first opening end is opened on the inner side of the wall, the second opening end is opened on the outer side of the wall, and the first opening end is located above the second opening end. The beneficial effect is that by setting the inclined steel pipe sleeve, the radiation leakage of the accelerator room can be effectively avoided, and the radiation protection capability of the entire accelerator room can be enhanced.
[0006] Furthermore, the radiation protection structure also includes a pipeline structure, which includes a first pipe, a second pipe, a third pipe and a fourth pipe connected in sequence, wherein the first pipe is inserted into the steel pipe sleeve; the second pipe is arranged horizontally; the third pipe is arranged symmetrically with the first pipe; and the fourth pipe is arranged horizontally and located above the ceiling. The beneficial effect is that the bending arrangement of the pipeline structure can effectively avoid the leakage of radiation in the pipeline space while ensuring the stability of the pipeline structure, further enhancing the radiation protection capability of the entire accelerator room.
[0007] Furthermore, the pipeline structure also includes a plurality of adapters, and the first pipe, the second pipe, the third pipe and the fourth pipe are connected to each other through the adapters. The beneficial effect is that the connection between the pipes is tighter, the leakage of radiation in the pipe space is avoided, and the radiation protection capability of the entire accelerator room is further enhanced.
[0008] Furthermore, the angle between the steel pipe sleeve and the wall is 45 degrees. Its beneficial effect is: while ensuring the structural stability of the steel pipe sleeve, the radiation protection capability is guaranteed to the greatest extent. If the pre-embedded angle of the steel pipe sleeve is too small, the radiation protection effect is low, and if the angle is too large, the pipeline resistance will increase. Therefore, the angle between the steel pipe sleeve and the wall is preferably 45 degrees.
[0009] Furthermore, the first opening end of the steel pipe sleeve is located between the suspended ceiling and the top plate.
[0010] Furthermore, the inner wall of the steel pipe sleeve is provided with a fireproof and heat-insulating layer, which has the beneficial effect of preventing the fire from spreading to the adjacent room through the gap between the pipe and the sleeve in case of fire.
[0011] The beneficial effect of the utility model is that the utility model can effectively avoid the radiation leakage of the accelerator room by pre-embedding the inclined steel pipe sleeve in the wall, thereby enhancing the radiation protection capability of the entire accelerator room.

[0014] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0015] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0016] like Figure 1 , 2 As shown, the utility model provides a radiation protection structure for penetrating a wall of a medical accelerator room with a pipe. The medical accelerator room comprises a floor 1, a ceiling 2, a suspended ceiling 3 located below the ceiling 2, and a wall 4. A steel pipe sleeve 5 is embedded in the wall 4. The steel pipe sleeve 5 can be a hollow cylindrical structure or a hollow cubic structure. It is arranged to penetrate the wall 4 and has two openings, including a first opening end 51 and a second opening end 52. The first opening end 51 opens to the inner side of the wall, and the second opening end 52 opens to the outer side of the wall. The first opening end 51 is located above the second opening end 52. It should be noted here that the holes passing through the wall, the embedded sleeves and the joints with the concrete are the weakest links in the entire radiation protection system. Improper handling will cause radiation leakage. Therefore, all the holes through the wall and the pipe holes cannot be straight, and should be processed in a zigzag manner to form a maze to prevent radiation leakage and enhance the radiation protection performance of the entire accelerator room. Preferably, the angle between the steel pipe sleeve 5 and the wall 4 is 45 degrees. If the angle is too small, the radiation protection effect is low. If the angle is too large, the pipeline resistance will increase. In order to ensure the stability of the overall structure and the radiation protection performance, it is advisable to set the angle between the steel pipe sleeve 5 and the wall 4 to 45 degrees.
[0017] Furthermore, in order to further enhance the radiation protection performance of the overall structure, the pipeline structure 6 is configured as a first pipe 61, a second pipe 62, a third pipe 63 and a fourth pipe 64 which are connected in sequence, wherein the first pipe 61 is matched with the steel pipe sleeve 5 and can be inserted into the steel pipe sleeve 5; the second pipe 62 is arranged horizontally; the third pipe 63 is arranged symmetrically with the steel pipe sleeve 5; the fourth pipe 64 is arranged horizontally and is located above the ceiling 3. Thus, the pipeline structure 6 is configured as a trapezoidal structure to avoid radiation leakage in the pipeline and further enhance the radiation protection performance of the overall structure.
[0018] Furthermore, in order to improve the sealing performance of the pipeline structure 6 , the pipes of the pipeline structure 6 are connected via an adapter 65 . Thus, the first pipe 61 , the second pipe 62 , the third pipe 63 and the fourth pipe 64 are interconnected via the adapter 65 .
[0019] Furthermore, in order to facilitate the subsequent arrangement of pipes, the first open end 51 of the steel pipe sleeve 5 is located between the suspended ceiling and the top plate.
[0020] Furthermore, a fireproof and heat-insulating layer 7 is provided between the steel pipe sleeve 5 and the first pipe fitting 61. On the one hand, it prevents the fire from spreading to the adjacent room through the gap between the pipe and the sleeve in case of fire; on the other hand, it plays a sealing role to prevent radiation from leaking out from the gap between the steel pipe sleeve 5 and the first pipe fitting 61, further improving the radiation protection performance of the overall structure.
[0021] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
