[0082] As Figures 1 to 5The detection device includes a detection component 30, an inlet channel component 10 and an outlet channel component 20. The detection component 30 has opposite first and second sides, and includes a detection channel and a detection assembly arranged on the side of the detection channel. The inlet channel component 10 is arranged on the first side of the detection component 30, and includes an inlet channel 110. The outlet channel component 20 is arranged on the second side of the detection component 30, and includes an outlet channel 210. The inlet channel 110, the detection channel 310 and the outlet channel 210 are in communication with each other. The inlet channel component 10 is configured with a first opening 100, the first opening 100 is in communication with the detection channel 310, and the first opening 100 can be switched between an open state and a closed state; and / or the outlet channel component 20 is configured with a second opening 200, the second opening 200 is in communication with the detection channel 310, and the second opening 200 can be switched between an open state and a closed state.

[0083] The detection device includes an inlet channel component 10, a detection component 30 and an outlet channel component 20 connected in sequence, and the inlet channel component 10, the outlet channel component 20 and the detection component 30 can be mounted on the base 50. The inlet channel component 10 is provided with an inlet channel 110, the detection component 30 is provided with a detection channel 310, and the outlet channel component 20 is provided with an outlet channel 210, and the inlet channel 110, the detection channel 310 and the outlet channel 210 are in communication with each other.

[0084] The detected object enters the inside of the detection device from the inlet of the inlet channel 110, moves to the detection channel 310, and the detection assembly arranged at the detection channel 310 detects the detected object, and after the detection is completed, the detected object moves to the outlet channel 210, and is further transferred to the outside of the detection device from the outlet of the outlet channel 210.

[0085] The detection component 30 has opposite first and second sides, and the inlet channel component 10 is located on the first side of the detection component 30, and the outlet channel component 20 is located on the second side of the detection component 30. The detection component 30 includes a support frame 31 and a detection assembly, and the support frame 31 includes a first support body 311, a second support body 312, a third support body, a fourth support body, a top support body and a bottom support body. The first support body 311 and the second support body 312 are opposite, the third support body and the fourth support body are opposite, the first support body 311 and the second support body 312 are arranged in a length direction of the detection device, and the third support body and the fourth support body are arranged in a width direction of the detection device. The inlet channel component 10 is connected with the first support body 311, and the outlet channel component 20 is connected with the second support body 312.

[0086] As Figure 2As shown, multiple supports enclose a detection channel 310, and the detection assembly is mounted on the inner wall of the support frame 31. The detection assembly includes a radiation source 32, a detector 33, and a grating assembly, with the radiation source 32 and detector 33 positioned opposite each other. The radiation source 32 can be installed at the lower left corner of the support frame 31, and the detector 33 at the upper right corner. The grating assembly includes multiple gratings, the number of which is set according to actual needs. For example, there may be three gratings: a first grating 34, a second grating 35, and a third grating 36.

[0087] The first grating 34 and the second grating 35 are disposed near the radiation source 32, and are spaced apart. The first grating 34 includes a first horizontal arm 341 and a first vertical arm 342, and the second grating 35 includes a second horizontal arm 351 and a second vertical arm 352. The third grating 36 is disposed near the detector 33, and includes a third horizontal arm 361 and a third vertical arm 362. The first horizontal arm 341, the second horizontal arm 351, and the third horizontal arm 361 are parallel to each other, and the first vertical arm 342, the second vertical arm 352, and the third vertical arm 362 are also parallel to each other.

[0088] When installing the grating assembly, the first grating 34 and the second grating 35 are first mounted on the fixture. Alignment and adjustment of the first grating 34 and the second grating 35 are completed in the laboratory. Then, the fixture is installed onto the support frame 31. Next, the third grating 36 is installed inside the support frame 31 and fine-tuned relative to the first grating 34 and the second grating 35. The adjustment effect of the third grating 36 can only be judged by the scanning imaging results. During the debugging process, repeated adjustments are required to achieve the desired effect.

[0089] like Figure 4 and Figure 5 As shown, the inlet channel component 10 is provided with a first opening 100, which is close to the first support 311 and communicates with the detection channel 310. The first opening 100 can be located at the top of the inlet channel component 10, the side of the inlet channel component 10, or both the top and side of the inlet channel component 10. When the first opening 100 is closed, the inlet channel 110 is a sealed channel. When the first opening 100 is open, since it communicates with the detection channel 310, operators can adjust or repair the detection components in the detection channel at the first opening 100.

[0090] In the existing technology, taking the debugging of the third grating 36 as an example, the operator needs to crawl into the detection channel from the entrance channel to adjust the installation position of the third grating 36. Each adjustment of the installation position is followed by one scan image. Based on multiple installation positions and multiple scan images taken for multiple installation positions, the optimal installation position of the third grating 36 is determined. During the debugging process, the operator needs to crawl in and out of the detection channel multiple times, resulting in low debugging efficiency and inconvenient operation.

[0091] In this embodiment, opening the first opening 100 allows the operator to debug or repair the detection components within the detection channel 310, as the first opening 100 is connected to the detection channel 310. Closing the first opening 100 allows for scanning and imaging. During the debugging process, the first opening 100 needs to be opened and closed multiple times, which improves both operational convenience and debugging efficiency.

[0092] A baffle plate that can open or close the first opening 100 can be provided at the first opening 100, so that the first opening 100 can switch between an open state and a closed state.

[0093] like Figure 4 and Figure 5 As shown, the outlet channel component 20 is provided with a second opening 200, which is close to the second support 312 and communicates with the detection channel 310. The second opening 200 can be located at the top of the outlet channel component 20, the side of the outlet channel component 20, or both the top and side of the outlet channel component 20. When the second opening 200 is closed, the outlet channel 210 is a sealed channel. When the second opening 200 is open, since it communicates with the detection channel 310, operators can adjust or repair the detection components within the detection channel 310 through the second opening 200.

[0094] A baffle plate that can open or close the second opening 200 can be provided at the second opening 200, so that the second opening 200 can switch between the open state and the closed state.

[0095] Similarly, by opening the second opening 200, operators can debug or repair the detection components within the detection channel 310 at the second opening 200. Closing the second opening 200 allows for scanning and imaging. During the debugging process, the second opening 200 needs to be opened and closed multiple times, which improves both operational convenience and debugging efficiency.

[0096] The first shielding door curtain is arranged at the entrance of the entrance passage component 10, and the second shielding door curtain is arranged at the exit of the exit passage component 20. The first opening 100 and the second opening 200 are in a closed state, and the entrance passage 110, the detection passage 310 and the exit passage 210 form a closed passage, so that the detected object at the detection passage 310 can be detected.

[0097] It can be understood that the first opening 100 can be arranged only on the entrance passage component 10, the second opening 200 can be arranged only on the exit passage component 20, or the first opening 100 is arranged on the entrance passage component 10 and the second opening 200 is arranged on the exit passage component 20. The first opening 100 is in an open state, and the detection assembly can be debugged or maintained at the first opening 100; the second opening 200 is in an open state, and the detection assembly can be debugged or maintained at the second opening 200; and the first opening 100 and the second opening 200 are in an open state, and the detection assembly can be debugged or maintained at the first opening 100 and the second opening 200.

[0098] In the embodiment of the utility model, the entrance passage component 10 is provided with the first opening 100, the first opening 100 is communicated with the detection passage 310, the exit passage component 20 is provided with the second opening 200, the second opening 200 is communicated with the detection passage 310, and the first opening 100 and / or the second opening 200 can debug or maintain the detection assembly at the first opening 100 and / or the second opening 200 in the open state, which is beneficial to the convenience and rapidity of debugging operation or maintenance operation.

[0099] As shown in Figure 3 , Figure 4 and Figure 5 , in the optional embodiment, the entrance passage component 10 comprises a first bearing body 11 and a first shielding piece 12. The first bearing body 11 defines the entrance passage 110, and the first bearing body 11 is provided with the first opening 100 at one end close to the detection component 30; the first shielding piece 12 is detachably connected with the first bearing body 11, and the first shielding piece 12 can open or shield the first opening 100.

[0100] Exemplarily, the first bearing body 11 can be a square bearing body, and the first bearing body 11 comprises a first top plate body 111, two first side plate bodies 112 and a first bottom plate body connected in sequence from head to tail, and the first top plate body 111, the two first side plate bodies 112 and the first bottom plate body form the entrance passage 110.

[0101] The first bearing body 11 is provided with the first opening 100 at one end facing the first support body 311 of the detection component 30, and the size of the first opening 100 is set according to actual requirements, which can provide suitable operation space for the operator.

[0102] Optionally, the first opening 100 is extended by the first top plate body 111 to the two first side plate bodies 112, i.e., the first opening 100 is formed by the notch on the first top plate body 111 and the notches on the two first side plate bodies 112, and the sizes of the notches on the two first side plate bodies 112 can be different. For example, in the vertical direction, the notch on one of the first side plate bodies 112 is close to the first top plate body 111, and the notch on the other first side plate body 112 is close to the first bottom plate body.

[0103] When the first opening 100 is in the open state, the notch on the first side plate body 112 is close to the first bottom plate body, which can provide sufficient operation space for the operator. In addition, the notch on one of the first side plate bodies 112 is close to the first top plate body 111, and the notch on the other first side plate body 112 is close to the first bottom plate body, which is beneficial to reduce the area of the first opening 100, and thus beneficial to the miniaturization and light weight of the first shielding member 12, facilitating the taking operation of the first shielding member 12 or the application of external force to the first shielding member 12.

[0104] The size and shape of the first shielding member 12 are adapted to the size and shape of the first opening 100. The first shielding member 12 is in the shape of an approximate U, and the first shielding member 12 includes a first top shielding body 121 and two first side shielding bodies 122 connected to the two sides of the first top shielding body 121. When the first shielding member 12 shields the first opening 100, the first top shielding body 121 shields the notch on the first top plate body 111, and the first side shielding body 122 shields the notch on the first side plate body 112.

[0105] The first shielding member 12 and the first carrier 11 can be connected by screwing, clamping or sliding connection. When the first shielding member 12 is placed at the first opening 100, the first shielding member 12 shields the first opening 100; when the first shielding member 12 is removed from the first opening 100, the first opening 100 is in the open state.
