[0024] See also Figure 1-5 , this embodiment provides a technical solution: a channel-type radiation detection device, comprising a main support seat 1, a locking pin 8 and a locking unit 9;

[0025] Main support seat 1: Its left end is slidably connected to the auxiliary support seat 2, and the upper ends of the main support seat 1 and the auxiliary support seat 2 are rotatably connected to the lower column 3. The main support seat 1 and the auxiliary support seat 2 are installed at the passage opening, and the distance between the main support seat 1 and the auxiliary support seat 2 can be adjusted according to the width of the passage opening. When adjusting, the auxiliary support seat 2 can be pulled to the right to adjust the distance between the two lower columns 3. The upper ends of the two lower columns 3 are slidably connected to the upper column 4, and the lower column 3 and the upper column 4 form a channel column structure. The lower ends of the lower columns 3 are movably sleeved with a locking sleeve 10. The main support seat 1 and The upper ends of the secondary support bases 2 extend to the interior of the vertically corresponding locking sleeves 10. The locking sleeves 10 limit the rotation of the lower column 3 and also include a protective plate 11. There are two protective plates 11. The two protective plates 11 are arranged on the right side of the lower column 3 on the left. The radiation monitoring sensor 5 is located between the two protective plates 11. The right end of the protective plate 11 is higher than the right side of the radiation monitoring sensor 5. The protective plate 11 provides protection for the radiation monitoring sensor 5 to avoid damage. It also includes a warning light 7. The warning light 7 is arranged at the upper end of the upper column 4 on the left. The input end of the warning light 7 is electrically connected to the output end of the controller 6;

[0026] The locking pin 8 is used to lock the upper column 4. The locking pin 8 includes a pin shaft 81, a retaining ring 82, a spring 83 and a positioning shell 84. The pin shaft 81 is slidably connected to the upper end of the front side of the lower column 3. The rear end of the pin shaft 81 is movably plugged into the longitudinally corresponding upper column 4. A retaining ring 82 is provided in the middle of the outer arc surface of the pin shaft 81. The front end of the pin shaft 81 is movably sleeved with a spring 83. The upper end of the front side of the lower column 3 is provided with a positioning shell 84. The spring 83 is located between the retaining ring 82 and the positioning shell 84. When the pin shaft 81 is pulled forward, the pin shaft 81 drives the retaining ring 82 to move and compress the spring 83. At the same time, the pin shaft 81 is separated from the upper column 4. The pin shaft 81 no longer positions the upper column 4, and the positioning shell 84 provides support for the spring 83.

[0027] The locking unit 9 is used for locking the main support seat 1 and the auxiliary support seat 2. The locking unit 9 includes a pull rod 92 and a pressure rod 93. The pull rod 92 is slidably connected to the inside of the auxiliary support seat 2. The left end of the pull rod 92 is rotatably connected to the pressure rod 93. The lower end of the pressure rod 93 is matched with the main support seat 1. The locking unit 9 also includes an internal threaded tube 91. The internal threaded tube 91 is rotatably connected to the inside of the auxiliary support seat 2. The right end of the pull rod 92 is threadedly connected to the internal threaded tube 91. The locking unit 9 also includes an inner hexagonal sleeve 94. The inner hexagonal sleeve 94 is connected to the inner hexagonal sleeve 94. 4 is set at the right end of the internal threaded tube 91, and the internal threaded tube 91 is rotated by inserting the internal hexagonal wrench into the internal hexagonal sleeve 94. The internal threaded tube 91 pulls the pressure rod 93 to the right through the pull rod 92. The pressure rod 93 is tilted to the right from bottom to top. The upper right end of the pressure rod 93 contacts the left end of the auxiliary support seat 2. In the process of pulling to the right, the pressure rod 93 rotates around the rotating shaft at the right end of the pull rod 92, and the lower left end of the pressure rod 93 rotates and moves downward to squeeze the bottom wall of the main support seat 1, thereby achieving control of the channel width;

[0028] Among them: it also includes a radiation monitoring sensor 5 and a controller 6. The radiation monitoring sensor 5 is arranged on the right side of the lower column 3 on the left side, and the controller 6 is arranged on the front side of the lower column 3 on the left side. The output end of the radiation monitoring sensor 5 is electrically connected to the input end of the controller 6, and the input end of the controller 6 is electrically connected to an external power supply. The radiation monitoring sensor 5 monitors the radiation of people and objects passing by, and converts the radiation value into an electrical signal and transmits it to the controller 6. The controller 6 processes the information. When the radiation value is greater than the set value, the controller 6 controls the warning light 7 to work and issue a warning.

[0029] The working principle of a channel type radiation detection device provided by the present invention is as follows: when in use, the main support seat 1 and the auxiliary support seat 2 are installed at the channel opening, and the distance between the main support seat 1 and the auxiliary support seat 2 can be adjusted according to the width of the channel opening. When adjusting, the auxiliary support seat 2 can be pulled to the right to adjust the distance between the two lower columns 3. After the adjustment is completed, the internal threaded tube 91 is rotated inside the internal hexagonal sleeve 94 by inserting an inner hexagonal wrench. The internal threaded tube 91 is pulled to the right by the pull rod 92 to pull the pressure rod 93. The pressure rod 93 is tilted to the right from bottom to top. The upper right end of the pressure rod 93 contacts the left end of the auxiliary support seat 2. In the process of pulling to the right, the pressure rod 93 will rotate around the rotating shaft at the right end of the pull rod 92. The lower left end of the pressure rod 93 rotates and moves downward to squeeze the bottom wall of the main support seat 1, thereby realizing the control of the channel width. The radiation monitoring sensor 5 monitors the radiation of the people and objects passing by, and The radiation value is converted into an electrical signal and transmitted to the controller 6. The controller 6 processes the information. When the radiation value is greater than the set value, the controller 6 controls the warning light 7 to work to provide a warning. After use, the internal threaded tube 91 can be rotated, and the pressure rod 93 can loosen the main support seat 1, and then the main support seat 1 and the auxiliary support seat 2 are folded together. Then the pin shaft 81 is pulled forward, and the pin shaft 81 drives the retaining ring 82 to move the compression spring 83. At the same time, the pin shaft 81 is separated from the upper column 4, and the pin shaft 81 no longer positions the upper column 4. Then the upper column 4 can be retracted to the inside of the lower column 3. After the retraction is completed, the locking sleeve 10 on the right can be moved upward and separated from the auxiliary support seat 2, and then the lower column 3 on the auxiliary support seat 2 can be folded to the left. After the lower column 3 on the right is folded, the locking sleeve 10 on the left is moved upward, and then the lower column 3 on the left is folded, thereby reducing its own volume, facilitating transfer, and having good construction convenience.

[0030] It is worth noting that the radiation monitoring sensor 5, controller 6 and warning light 7 disclosed in the above embodiments can be freely configured according to the actual application scenario. The radiation monitoring sensor 5 can be a radiation monitoring sensor of model RAD-S101, the core chip of the controller 6 can be a single-chip microcomputer of model AT89S51, and the warning light 7 can be a warning light of model LTE-1101J. The controller 6 controls the operation of the radiation monitoring sensor 5 and the warning light 7 using methods commonly used in the prior art.
