As shown in FIGS. 1 to 8 , embodiments of the present disclosure provide a radiation inspection device. The radiation inspection equipment has an inspection state and a transport state, and mainly includes a radiation detection device and a protective wall 3 .

The radiation detection device includes a radiation source and a detector cooperating with the radiation source. In the inspection state, the radiation detection device has an inspection channel 5 for the object to be inspected to pass through. The term "passing" used here not only includes the radiation inspection equipment being stationary, and the inspected object moves through the inspection channel 5, but also includes the inspected object being stationary, and the radiation inspection equipment moves so that the inspected object passively passes through the inspection channel 5, and also includes the inspected object passing through the inspection channel 5 passively. The object and the radiation inspection equipment move at the same time, and the object to be inspected moves relatively from one end of the inspection channel 5 to the other end.

The protective wall 3 includes a plurality of wall bodies whose positions are variable so that the protective wall 3 is deformable. In the inspection state, the protective walls 3 are located on both sides of the inspection channel 5 to prevent radiation leakage. At least part of the wall of the protective wall 3 is closer to the radiation detection device in the direction of the inspection passage 5 than in the inspection state. For example, in some embodiments, in the transport state, the protective wall 3 is located inside the radiation detection device and/or attached to the radiation detection device.

The radiation inspection equipment in the embodiment of the present disclosure is deployed to the inspection state when inspecting objects such as containers and vehicles, and protective walls 3 are arranged on both sides of the inspection channel 5 to prevent radiation leakage. When the radiation inspection equipment performs radiation inspection The safety is high. When no inspection is required, such as during transport or storage, change the position of the protective wall 3 so that the radiation inspection equipment is in the transport state, reducing the space occupied by the radiation inspection equipment as a whole, and facilitating radiation. Check the overall transport of the equipment and the small footprint when stored. Since the radiation inspection equipment can be transported or stored as a whole, it is also beneficial to reduce the installation and commissioning work when it is used again, and it is beneficial for the radiation inspection equipment to be ready for inspection quickly. In the transportation state, the protective wall 3 is located inside the radiation detection device and/or attached to the radiation detection device, so that the space can be more fully utilized in the transportation state, which is more conducive to reducing the space occupied by the radiation inspection equipment as a whole. Radiation inspection equipment has a high overall stability in the transport state.

As shown in FIG. 3 and FIG. 4 , in some embodiments, in the transportation state, the protective wall 3 and the radiation detection device are enclosed to form a cuboid structure. The setting form of the transportation state makes the radiation inspection equipment more suitable for overall transfer transportation and storage.

As shown in FIGS. 1 to 8 , the radiation detection device includes a first cabin 2 and a jib 1 . The boom 1 is connected to the top of the first cabin body 2 in a variable height. The height of the jib 1 in the inspection state is higher than in the transport state. The height-variable arrangement of the arm frame 1 is beneficial to the radiation detection device having a higher inspection channel 5 height in the inspection state, which can inspect vehicles or containers with a higher height, so that the radiation detection device has a wider inspection range. The radiation detection device has a lower height in the transportation state, which is beneficial to the overall transfer and transportation of the radiation inspection equipment and reduces the space occupation during storage.

In some embodiments, the ray source is located in the first cabin 2, and the detector is located on the boom 1. In the inspection state, the protective wall 3 on the side close to the first cabin 2 has a first interval. At this time, the first cabin 2 may include a first shield to prevent radiation from leaking from the first compartment.

In this state, the detector is in the exact detection position.

The connection between the second detection part and the first detection part or the jib 1 is not limited to a hinge, for example, the second detection part can also be detachably connected to the corresponding position in the inspection state and the transport state.

In some embodiments, the radiation detection device may further include a locking structure for locking the position of the second detection part relative to the jib 1 in the inspection state and/or the transport state.

In the inspection state, four sets of walls are respectively arranged at both ends of the first cabin body 2 and the two ends of the second cabin body 4 along the extending direction of the inspection channel 5 . In the transport state, the four sets of walls are located between the side of the first cabin 2 away from the second cabin 4 and the side of the second cabin 4 away from the first cabin 2 . This setting is beneficial to realize the switching between the inspection state and the transport state of the radiation inspection equipment with high efficiency. In addition, the protective wall 3 of the radiation inspection equipment in the transportation state only occupies a small space other than the occupied space of the radiation detection device, and can even use the space occupied by the radiation detection device instead of occupying the space other than the occupied space of the radiation detection device.

In some embodiments, when multiple walls are divided into the aforementioned four groups of walls, two groups of walls in the four groups of walls can be rotatably connected to the first cabin body 2 along the extension direction of the inspection channel 5 both ends. The other two sets of walls in the four sets of walls can be rotatably connected to both ends of the second cabin body 4 along the extending direction of the inspection channel 5 . This setting is convenient for the radiation inspection equipment to switch between the inspection state and the transport state, the switching process saves time and effort, and facilitates accurate positioning between the protective wall 3 and the radiation detection device.

In some embodiments, in the inspection state, the protective wall 3 on the side close to the second cabin body 4 is continuously arranged. In this case, the protective work on one side of the second cabin body 4 is completely undertaken by the protective wall 3 . At this time, the second cabin body 4 does not need to be specially designed for protection.
