Description

Technical Field

[0001] This utility model relates to the field of radiation protection technology, specifically to an anti-ionizing radiation ventilation box and a container ventilation system. Background Technology

[0002] In the field of medical diagnostics, X-ray examination mobile units play a crucial role, providing a convenient and efficient physical diagnostic environment for patients. These units are designed as enclosed spaces, equipped with fresh air intakes and exhaust vents to ensure air circulation and cleanliness within the chamber. However, the radioactive equipment such as X-ray machines or CT scanners installed inside these units generate harmful X-rays during operation, posing a significant challenge to radiation protection.

[0003] To ensure radiation protection requirements are met during radiological diagnostic procedures, the shielding measures for the air intake and exhaust vents of the X-ray inspection cabin are particularly important. Currently, the solution used for the ventilation vents of X-ray inspection cabins is to use movable baffles to prevent harmful radiation from leaking into the external environment. However, this traditional shielding method has revealed a series of problems in practical applications.

[0004] Current movable baffle compensation measures have significant limitations. First, due to the presence of the movable baffle, ventilation operations in the mobile cabin must be performed when the X-ray or CT scanner is not in operation. This not only reduces the utilization efficiency of the mobile cabin but may also affect the continuity of the diagnostic process. Second, the baffle needs to be removed during ventilation operations, which poses a risk of residual radiation exposure, and the operation is cumbersome and prone to errors.

[0005] More seriously, if the baffle fails to move properly, it can obstruct the airflow to and from the fan, increasing the fan's resistance and potentially damaging it over time. Furthermore, when an X-ray or CT scanner is in operation, failure to properly shield the movable baffle could lead to the leakage of toxic radiation from inside the chamber into the external environment, causing unpredictable radiation damage to those nearby. Summary of the Invention

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the problem of poor operation efficiency and effect of radiation protection technology during cabin ventilation in the existing technology, and to provide a ventilation box for ionizing radiation protection.

[0008] In one embodiment of this utility model, it further includes a protective shell, and the first shielding mechanism and the second shielding mechanism are both disposed inside the protective shell. The protective shell is provided with a plurality of exhaust holes for ventilation.

[0009] In one embodiment of the present invention, the first shielding component further includes a first pressure plate, which is sleeved and supported on the first shielding frame to fix the position of the first shielding frame.

[0010] In one embodiment of the present invention, the second shielding component includes a third shielding frame and a second pressure plate, wherein the third shielding frame is disposed between the second pressure plate and the inner wall of the second assembly frame.

[0011] In one embodiment of the present invention, the first assembly frame includes a first connecting part and a second connecting part that are connected to each other. The ventilation fan is connected to the first connecting part, the second connecting part is arranged around the ventilation fan and extends along a first direction, and the first shielding frame is sleeved and supported on the outer surface of the second connecting part.

[0015] In one embodiment of the present invention, the ventilation fan includes a housing and fan blades, the housing is connected to the first assembly frame, and the fan blades are rotatably connected to the housing.

[0016] This utility model also provides a container ventilation system, which includes the aforementioned anti-ionizing radiation ventilation box.

[0017] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Example 1

[0030] See Figure 1As shown, this embodiment provides an anti-ionizing radiation ventilation box, which includes: a ventilation fan 200; a first shielding mechanism 300, the first shielding mechanism 300 including a first assembly frame 310 and a first shielding component 320, the ventilation fan 200 being connected to the first assembly frame 310 and communicating with the internal and external environment of the first assembly frame 310, the first shielding component 320 being disposed inside the first assembly frame 310, and including a first shielding frame 321 and a second shielding frame 323, wherein the first shielding frame 321 surrounds... The ventilation fan 200 is provided on its outer surface, and the second shielding frame 323 is embedded between the ventilation fan 200 and the side wall of the first assembly frame 310; the second shielding mechanism 400 is provided at a distance from the first shielding mechanism 300 in the first direction X, and includes the second assembly frame 410 and the second shielding component 420. The second shielding component 420 is connected to the inner surface of the second assembly frame 410, and the first shielding frame 321 extends along the first direction X into the interior of the second shielding component 420.

[0031] The ionizing radiation protection ventilation box described in this embodiment achieves multiple shielding protection for the air vents of the container through a first shielding mechanism 300 and a second shielding mechanism 400 arranged around the ventilation fan 200. The first shielding frame 321, the second shielding frame 323, and the third shielding frame 421 are respectively configured as shielding structures with different structures but capable of cooperating with each other. This fundamentally solves the risk of radiation leakage during ventilation in radioactive locations such as container houses. Furthermore, it eliminates the need for shutdown operation, enabling "ventilation while operating," which not only improves the efficiency of container house use but also significantly reduces operational complexity. Compared to conventional ventilation structures currently available, this application has significant advantages such as superior radiation protection, high operational efficiency, high automation, and wide applicability, and has broad application prospects in the industry.

[0032] It should be noted that, for ease of description, in this embodiment, the thickness direction of the anti-ionizing radiation ventilation box is defined as the first direction X, the width direction of the anti-ionizing radiation ventilation box is defined as the second direction Y, and the height direction of the anti-ionizing radiation ventilation box is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0033] See Figures 2 to 4As shown, the first shielding mechanism 300 and the second shielding mechanism 400 in this embodiment can achieve a double shielding effect in the first direction X. Simultaneously, the first shielding mechanism 300 can also shield the ventilation fan 200, thereby achieving all-around radiation protection without blind spots. Specifically, the first shielding frame 321 and the third shielding frame 421 are used for double shielding in the first direction X, and the second shielding frame 323 is used to shield the ventilation fan 200. All of the above shielding frames are preferably lead plates. Based on the physical properties of X-rays, their energy can be absorbed by the lead plate shielding layer, thus preventing them from penetrating to the external environment. Furthermore, to improve the stability of the working environment of this bellows, this embodiment also includes a protective shell 100. The first shielding mechanism 300 and the second shielding mechanism 400 are both disposed inside the protective shell 100. The protective shell 100 is provided with multiple exhaust holes 110 for ventilation.

[0034] The ventilation fan 200 in this embodiment includes a housing 220 and a fan blade 210. The housing 220 is connected to the first assembly frame 310 and is detachably connected to the first assembly frame 310 by bolts or other mechanisms. The fan blade 210 is rotatably connected to the housing 220.

[0035] See Figure 1 The first assembly frame 310 in this embodiment includes a first connecting portion 311 and a second connecting portion 312 connected to each other. The ventilation fan 200 is connected to the first connecting portion 311. The second connecting portion 312 is arranged around the ventilation fan 200 and extends along the first direction X. The first shielding frame 321 is sleeved and supported on the outer surface of the second connecting portion 312. Further, the first connecting portion 311 includes an assembly panel 3111 and a first sidewall 3112. The assembly panel 3111 has an assembly opening at its center. The ventilation fan 200 is connected to the assembly panel 3111 and is arranged corresponding to the assembly opening. The first sidewall 3112 extends from the edge of the assembly panel 3111 toward the second shielding mechanism 400. The second shielding frame 323 is embedded in the space enclosed by the first sidewall 3112, the assembly panel 3111, and the first shielding frame 321. Specifically, in this embodiment, the first connecting part 311 provides an installation platform for the ventilation fan 200, and the second connecting part 312 provides an installation platform for the first shielding component 320. Simultaneously, the second connecting part 312 can restrict the specific assembly position of the first shielding component 320 to improve the stability of the air box. Specifically, in this embodiment, the first connecting part 311 and the second connecting part 312 are fixedly connected and are essentially an integral unit. In different embodiments, they can also be configured as a detachable and adjustable structure, thereby improving the flexibility of use of this application. This utility model does not impose specific limitations in this regard.

[0036] See Figures 4 to 6 As shown, in this embodiment, the first shielding component 320 further includes a first pressure plate 322, which is sleeved and supported on the first shielding frame 321 to fix the position of the first shielding frame 321. The first pressure plate 322 is used to fix the first shielding frame 321, and at the same time cooperates with the first connecting part 311 to realize the support and compression of the second shielding frame 323, thereby improving the overall connection stability of the first shielding component 320.

[0037] See Figure 3 and Figure 7 As shown, the second assembly frame 410 includes a base plate 411 and a second side wall 412. The second side wall 412 extends from the edge of the base plate 411 toward the first shielding mechanism 300. The second shielding component 420 is disposed within the space enclosed by the second side wall 412 and the base plate 411. Further, the second shielding frame 323 is configured with the same "U"-shaped structure as the second assembly frame 410, thereby improving the connection stability between the second assembly frame 410 and the second shielding component 420. In this embodiment, the second shielding component 420 includes a third shielding frame 421 and a second pressure plate 422. The third shielding frame 421 is disposed between the second pressure plate 422 and the inner wall of the second assembly frame 410, and it also serves to limit the operational stability of the third shielding frame 421, thereby avoiding the problem of reduced shielding effect due to the third shielding frame 421 shifting or tilting.

[0038] Example 2

[0039] This embodiment provides a container ventilation system, which includes the aforementioned anti-ionizing radiation ventilation box.

[0040] In summary, the anti-ionizing radiation ventilation box and container ventilation system described in this utility model achieves multiple shielding protection for the container air vents through the first shielding mechanism 300 and the second shielding mechanism 400 arranged around the ventilation fan 200. The first shielding frame 321, the second shielding frame 323, and the third shielding frame 421 are respectively designed with different structures but can cooperate with each other. This fundamentally solves the risk of radiation leakage during ventilation in radioactive locations such as container rooms. Furthermore, it eliminates the need for shutdown operation, enabling "ventilation while operating," which not only improves the efficiency of container use but also significantly reduces operational complexity. Compared to conventional ventilation structures at present, this application has significant advantages such as good radiation protection, high operating efficiency, high degree of automation, and wide applicability, and has broad application prospects in the industry.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
