Description

Technical Field

[0001] The utility model relates to the technical field of protective measures for radiation rooms, in particular to a radiation leakage prevention structure for ventilation and exhaust ports in a radiology room. Background Art

[0002] The internal space of the radiation room is usually protected by shielding materials such as lead plates or barium plates to prevent the radiation from spilling out. The conventional practice is to avoid or reduce the openings in the walls of the room, but the radiology room is usually required to have ventilation vents, central air conditioning inlets or gas fire extinguishing system pressure relief vents, which are directly attached to the outside of the openings.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing lead louver structure cannot close the ventilation vents, central air-conditioning air inlets or gas fire extinguishing system pressure relief vents. These parts destroy the overall protection structure shielding, causing radiation leakage. At the same time, they will also reduce the exhaust volume of the ventilation vents or hinder the opening of the pressure relief vent valve, which cannot meet the usage requirements of multiple scenarios. Utility Model Content

[0005] The purpose of the utility model is to provide a radiation leakage prevention structure for the ventilation and exhaust vents of a radiology room, so as to solve the problem raised in the above-mentioned background technology that the existing lead louver structure, the ventilation vents, the central air-conditioning air inlet or the pressure relief vents of the gas fire extinguishing system cannot be closed, these parts destroy the shielding of the overall maintenance structure, cause radiation leakage, and also reduce the exhaust volume of the ventilation vents, or hinder the opening of the pressure relief vent valve to the outside, and cannot adapt to the use requirements of multiple scenarios.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a radiation leakage prevention structure for ventilation and exhaust ports of a radiology room, comprising:

[0008] A main body component, wherein the main body component includes a wall;

[0009] an abatement assembly, the abatement assembly comprising a steel structural frame, a steel structural barrier, a second lead sheet, an exterior decorative surface, and a second vent;

[0010] The steel structure frame is clamped on the wall, and the steel structure interlayer has two layers, which are welded inside the steel structure frame. The second lead plate is welded to the inner side of the steel structure frame and the upper surface of the steel structure interlayer respectively, and the outer decorative surface is fixed to the outer surface of the steel structure frame by screws. The second vent is opened on the second lead plate and the outer decorative surface at the lower end of the steel structure frame.

[0011] Furthermore, the two groups of steel structure partitions are arranged alternately up and down, and the second ventilation opening is opened directly below the lower steel structure partition.

[0012] Further, the main body assembly also includes a first lead plate and a first vent;

[0013] The first ventilation hole is opened in the upper section of the wall, and the first lead plate is wrapped around the inner side of the wall and the inner surface of the first ventilation hole four times.

[0014] Further, it also includes a connection component;

[0015] The connecting assembly includes an L-shaped limiting plate and a clamping plate;

[0016] There are two groups of L-shaped limit plates, which are respectively located at the upper and lower ends of the first vent. The clamping plates are welded to the upper and lower ends of the steel structure frame and clamped in the L-shaped limit plates.

[0017] Furthermore, the connection assembly also includes an adjustment rod and a pressure plate;

[0018] The adjusting rod passes through and is rotatably connected to the middle of the L-shaped limiting plate below; one end of the adjusting rod located in the L-shaped limiting plate is rotatably connected to the middle of the pressing plate; and the pressing plate is movably connected in the L-shaped limiting plate.

[0019] Furthermore, the connection assembly also includes a spring and a clamping plate;

[0020] The spring is connected between the upper L-shaped limiting plate and the clamping plate through screws, and the clamping plate is movably connected in the upper L-shaped limiting plate.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. The utility model, through the setting of the reduction component, sets a steel structure frame and a steel structure interlayer outside the first vent, fixes the second lead plate inside the steel structure and on the steel structure interlayer, and sets the outer decorative surface for aesthetic purposes. This setting, according to the characteristic of X-rays propagating in a straight line in the medium, the radiation dose rate is inversely proportional to the square of the distance from the radiation source. The greater the distance from the radiation source, the smaller the dose rate at that location. Since the radiation can only travel in a straight line, the radiation protection is shielded by the set bends, the number of reflections is increased, and the radiation equivalent is attenuated by distance, so that the radiation escaping from the hole "extends" the propagation distance to reduce the impact on the surrounding environment. At the same time, the second vent is opened at the bottom to meet the ventilation needs.

[0023] 2. The utility model, through the connection component provided, uses the card plate to directly insert into the L-shaped limit plate, the upper clamping plate clamps the upper card plate under the action of the spring, and the lower rotating adjustment rod drives the pressure plate to press the lower card plate. This setting is convenient for rapid disassembly and assembly of the reduction components. BRIEF DESCRIPTION OF THE DRAWINGS
