Description

Technical Field

[0001] This utility model relates to the field of radiation source protection technology, and in particular to a radiation source transport vehicle. Background Technology

[0002] When professional testing institutions conduct experiments such as material performance analysis and non-destructive testing, radioactive sources become indispensable key experimental resources due to their unique physical properties. Among them, the cobalt-60 gamma-ray radioactive source, with its advantages of high radiation energy, strong penetrating power, long half-life, and stable radiation intensity, is widely used in scenarios such as internal defect detection of metallic materials, aging performance research of polymer materials, and compositional analysis of some special samples, providing important technical support for testing institutions to accurately obtain experimental data and ensure the reliability of test results.

[0003] However, while cobalt-60 gamma-ray sources play a crucial role, they also pose significant safety risks. As ionizing radiation, gamma rays, if not properly protected, can cause severe damage to human tissues, including disrupting cell structure, inducing gene mutations, and, with prolonged or excessive exposure, potentially leading to irreversible health hazards such as cancer and hematopoietic dysfunction. Furthermore, they can cause radiation pollution to the surrounding laboratory environment. Currently, when transporting radioactive sources, traditional lead-shielded containers are typically used to carry the cobalt-60 gamma-ray source, which is then moved to the experimental area manually or using ordinary trolleys. However, this method has significant drawbacks. Traditional lead containers are heavy, and manual handling is not only labor-intensive but also carries the risk of tilting and collisions during transport. If the container's seal is compromised, gamma-ray leakage will directly threaten the safety of operators. Moreover, ordinary trolleys lack specific shielding designs, serving only a load-bearing function and failing to further reduce the radiation dose during transport. Operators must maintain a considerable distance from the trolley, resulting in low transport efficiency and poor maneuverability in narrow laboratory aisles, increasing the risk of collisions with other experimental equipment or personnel.

[0004] There are also technologies that improve transport vehicles specifically designed for moving radioactive sources. For example, Chinese patent CN213502526U discloses a protective device for transporting Ir-192 radioactive sources. This device designs the transport vehicle as a handcart with drawers inside, and lead plates are placed around the drawers. The radioactive source is placed inside the drawers. This effectively prevents accidents such as loss or dropping of the radioactive source.

[0005] However, when using transport devices like those described above, once the radioactive source is transported to the experimental location, operators must first open the protective cover of the lead shielding container, remove the radioactive source, and install it onto the specialized experimental apparatus before conducting tests. During this process, operators need to be in close contact with the radioactive source, and even with protective equipment, they still face the risk of radiation exposure. Furthermore, the cumbersome procedures for handling the radioactive source not only prolong experimental preparation time but also risk causing the source to fall or be damaged due to improper handling, further increasing safety hazards. In addition, some experiments require frequent movement of the radioactive source between different testing stations to complete multiple sets of tests, necessitating repeated handling after each movement. This significantly reduces experimental efficiency and exponentially increases the frequency and risk of radiation exposure. Utility Model Content

[0006] This invention aims to provide a radioactive source transport vehicle to address the problem that existing radioactive sources cannot simultaneously meet the requirements of transportation and use.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A radioactive source transport vehicle is provided, including a top cover; a box body, the top cover being installed on the top of the box body, the radioactive source being installed inside the box body, and an output port being provided on at least one end face of the box body, the output port being aligned with the output channel of the radioactive source; the box body and the top cover being made of lead plates; a protective door being provided on the end face of the box body, covering the output port; and wheels being installed on the bottom of the box body.

[0008] The combined design of the output port and the protective door effectively prevents the leakage of radiation from the radioactive source when the transport vehicle is in transit or not in use. At the same time, when it is needed, the radioactive source can be used directly without removing it.

[0009] In one embodiment, a first output port and a first protective door are provided on the front end face of the housing, and the position of the first protective door matches the first output port.

[0010] In one embodiment, a second output port and a second protective door are provided on the rear end face of the housing, and the position of the second protective door matches that of the second output port.

[0011] By using the first output port located on the front face of the housing and the second output port located on the rear face of the housing, when the radiation source is needed, any output port can be used flexibly for testing experiments according to its position, or output can be performed in two directions simultaneously.

[0012] In one embodiment, a safety lock is also connected between the top cover and the housing.

[0013] The safety lock secures the housing and the top cover, preventing the radioactive source from being lost.

[0014] In one embodiment, a mounting groove is provided at the bottom of the housing, and the radiation source is installed in the mounting groove.

[0015] In one embodiment, the radioactive source includes a radioactive source body and a mounting frame, the radioactive source body being placed in the mounting frame and the mounting frame being installed in the mounting slot.

[0016] In one embodiment, the mounting bracket includes a base frame and side frames, the shape of the base frame matching the shape of the mounting groove, and the two side frames being vertically mounted on both sides of the base frame.

[0017] In one embodiment, the output channel is provided on at least one end face of the radioactive source body, and when the radioactive source is placed in the transport vehicle, the output channel is aligned with the output port.

[0018] In one embodiment, a push rod is also installed on the housing.

[0019] In one embodiment, the wheel is a swivel wheel.

[0020] In summary, the radioactive source transport vehicle provided by this utility model, through the combined design of the output port and the protective door, can effectively prevent radiation leakage from the radioactive source when the vehicle is being transported or not in use. Furthermore, when needed, the radioactive source can be used directly without removing it. Moreover, by having multiple output ports on different end faces, any output port can be flexibly used for testing experiments according to its location, or multiple directions can be output simultaneously.

Detailed Implementation

[0027] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Furthermore, the radioactive source mentioned in the present utility model can be the radioactive source itself or a flaw detector with a radioactive source, such as a cobalt-60 gamma-ray flaw detector.

[0028] like Figure 1 As shown, this utility model provides a radioactive source transport vehicle 1, including a body 11 and wheels 12 mounted on the bottom of the body 11. The body 11 has a generally rectangular parallelepiped structure and is entirely composed of lead plates. Four wheels 12 are located at the four corners of the bottom of the body 11. The wheels 12 can be in the form of casters to facilitate the movement of the transport vehicle 1. A push rod 13 is also mounted on the body 11 for pushing and pulling the transport vehicle 1. In this embodiment, the push rod 13 is fixedly mounted in a "U" shape on both sides of the body 11, and the pusher is located at the rear end of the body 11. In other embodiments, the pusher of the push rod 13 can be switched between the front and rear ends of the body 11, facilitating the change of the transport vehicle 1's direction of movement.

[0029] The vehicle body 11 includes a top cover 111 and a housing 112. The top cover 111 is installed on top of the housing 112, forming a relatively sealed structure with the housing 112. The radiation source 2 (not shown in the figure) is placed inside the housing 112. A safety lock 113 is also connected between the top cover 111 and the housing 112. When the radiation source 2 is placed inside the housing 112, the safety lock 113 locks the housing 112 and the top cover 111, preventing the radiation source 2 from being lost. The rear ends of the top cover 111 and the housing 112 are rotatably connected, allowing the top cover 111 to be rotated open. The top cover 111 is also provided with a handle 114 for easy opening. A first output port 115 (dashed line in the figure) is opened on the front end face of the housing 112. The first output port 115 communicates with the inner cavity of the housing 112 and is aligned with the front end of the radiation source 2, for connecting the radiation source 2 to external equipment. A first protective door 116 is also installed on the front surface of the housing 112. The position of the first protective door 116 matches the first output port 115. When the transport vehicle 1 is in transit or when the radiation source 2 is not needed, the first protective door 116 covers the first output port 115. When the vehicle arrives at the target experimental site for testing, the first protective door 116 can be opened, and the radiation source 2 can be used directly by connecting the first output port 115 through a pipe. Through the cooperative design of the first output port 115 and the first protective door 116, the transport vehicle 1 can effectively prevent radiation leakage from the radiation source 2 when in transit or not in use. At the same time, when needed, the radiation source 2 can be used directly without removing it.

[0030] like Figure 2 As shown, a second output port 117 (the dotted line in the figure) is also provided on the rear end face of the housing 112. Similarly, the second output port 117 communicates with the inner cavity of the housing 112 and is aligned with the rear end of the radiation source 2, used to connect the radiation source 2 to external equipment. A second protective door 118 is also installed on the rear end face of the housing 112. The position of the second protective door 118 matches the second output port 117. When the transport vehicle 1 is in transit or when the radiation source 2 is not needed, the second protective door 118 covers the second output port 117. When the vehicle arrives at the target experimental site for testing, the second protective door 118 can be opened, and the radiation source 2 can be used directly by connecting the second output port 117 through a pipe.

[0031] By using the first output port 115 located on the front end of the housing 112 and the second output port 117 located on the rear end of the housing 112, when the radiation source 2 is needed, any output port can be used flexibly for detection experiments according to its position, or outputs in two directions can be performed simultaneously.

[0032] like Figure 3 As shown, the bottom of the box 112 is provided with an installation groove 119 for placing the radioactive source 2. The installation groove 119 is set in the shape of "II". When the radioactive source 2 is installed in the installation groove 119, the "II" shaped groove can keep the radioactive source 2 relatively stable and will not tip over or move due to the movement of the transport vehicle 1.

[0033] like Figure 4 As shown, the radioactive source 2 includes a radioactive source body 21 and a mounting frame 22. The radioactive source body 21 is placed in the mounting frame 22 and installed into the mounting groove 119 via the mounting frame 22. The mounting frame 22 includes a bottom frame 221 and side frames 222. The bottom frame 221 matches the shape of the mounting groove 119, both being "II" shaped. The two side frames 222 are vertically installed on both sides of the bottom frame 221. The bottom of the radioactive source body 21 rests on the bottom frame 221, and the two sides of the radioactive source body 21 pass through the side frames 222. Furthermore, a first output channel 211 is provided on the front end face of the radioactive source body 21. When the radioactive source 2 is placed in the transport vehicle 1, the first output channel 211 is aligned with the first output port 115, and the radioactive source 2 is connected to external equipment through the first output channel 211. Similarly, a second output channel (not shown in the figure) is also provided on the rear end face of the radiation source body 21. The second output channel is aligned with the second output port 117 and the radiation source 2 is connected to external equipment through the second output channel.

[0034] In summary, through the combined design of the first output port 115 and the first protective door 116, this utility model effectively prevents radiation leakage from the radioactive source 2 when the transport vehicle 1 is in transport or not in use. Furthermore, when needed, the radioactive source 2 can be used directly without removing it. Additionally, by using the first output port 115 located on the front face of the housing 112 and the second output port 117 located on the rear face of the housing 112, when the radioactive source 2 is required, either output port can be flexibly used for testing experiments, or output can be performed simultaneously in two directions.

[0035] Although the present invention has been described and illustrated in detail with reference to preferred embodiments, the present invention is not limited to the disclosed examples, and those skilled in the art can derive other variations therefrom without departing from the protection scope of the present invention.
