[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0020] Example: Please refer to Figure 1-4A railway transportation train security inspection system includes a radiation source room 1 and a detection frame 2. The radiation source room 1 and the detection frame 2 are respectively arranged on both sides of the train track. The radiation source room 1 and the detection frame 2 are connected by a pipeline 8. The pipeline 8 bypasses the train track from the ground to facilitate the wiring of the pipeline 8. The pipeline 8 includes a power line for providing power and an optical fiber for transmitting a control signal. When a train passes through the radiation source room 1, the optical fiber automatically senses a signal, so that the radiation source room 1 starts working, thereby scanning and detecting the train carriage 17; an infrared detector 15 is installed on the detection frame 2. Since there are usually multiple carriages 17 connected in series on a train, multiple carriages pass through the radiation source room 1 continuously when the train is running. Through the infrared detector The detector 15 is convenient for distinguishing the scanning time of each carriage 17. When each carriage passes through the radiation source room 1, the radiation source room 1 performs high-speed scanning on the carriage to achieve efficient detection of the container; the radiation source room 1 includes a box body 3, a collimator 4 and a radiation source 5 for emitting X-rays, the radiation source 5 is arranged in the box body 3, the collimator 4 is arranged at the emitting end of the radiation source 5, the detection frame 2 includes a vertical section 201 and an inclined section 202, the inclined setting can further expand the receiving area of the X-rays, correspondingly, the radiation source 5 is also inclined, the vertical section 201 is provided with a first receiving plate 6, the inclined section 202 is provided with a second receiving plate 7, the collimator 4 is used to control the range of X-ray emission, specifically, the collimator The straightener 4 includes a lead plate 9, which is fixedly connected to the box body 3. The lead plate 9 can effectively absorb and block X-rays to prevent the X-rays from irradiating places other than the first receiving plate 6 and the second receiving plate 7. A light path is vertically arranged in the middle of the lead plate 9. The X-rays emitted by the ray source 5 are irradiated to the first receiving plate 6 and the second receiving plate 7 through the light path. The total height of the first receiving plate 6 and the second receiving plate 7 connected together is higher than the height of the train carriage 17, and the light receiving area of the first receiving plate 6 and the second receiving plate 7 is large, which can absorb X-rays with high quality, so that the imaging quality is better; aluminum plates 12 are installed around and on the top of the detection frame 2, and the first receiving plate 6 and the second receiving plate 7 are installed on the aluminum plates. On the inner side of 12, on the one hand, the aluminum plate 12 has a low ability to absorb X-rays, so it is convenient for the first receiving plate 6 and the second receiving plate 7 to absorb X-rays, and on the other hand, the aluminum plate 12 can play a role in dust and moisture prevention; the detection frame 2 is fixedly installed on the terrace 16, and the terrace 16 is formed into a ground cage with a certain height by a steel frame, and the ground cage is paved with cement slabs, so the terrace 16 can play a role in flood prevention; a first inspection door 13 is provided on the aluminum plate 12, and a second inspection door 14 is provided on the side wall of the box body 3, and maintenance is convenient through the first inspection door 13 and the second inspection door 14; heat dissipation windows 10 are provided on both sides of the box body 3, and an air conditioner 11 is installed in the box body 3, and heat dissipation is convenient through the heat dissipation windows 10 and the air conditioner 11.
[0021] The working principle of this embodiment is as follows: when in use, if a train passes through the radiation source room 1, the optical fiber automatically senses, causing the radiation source room 1 to start working, the radiation source 5 emits X-rays to scan and detect the train carriage 17, and receives the X-ray signal through the first receiving plate 6 and the second receiving plate 7. The scanning time of each carriage 17 is distinguished by the infrared detector 15. When the train leaves the radiation source room 1, the radiation source room 1 stops working; wherein, the lead plate 9 can effectively absorb and block X-rays to prevent the X-rays from irradiating places other than the first receiving plate 6 and the second receiving plate 7. An optical path is vertically arranged in the middle of the lead plate 9. The X-rays emitted by the radiation source 5 are irradiated onto the first receiving plate 6 and the second receiving plate 7 through the optical path.
