The safety detection device on the gantry is a specialized device used to quickly detect whether personnel, vehicles, and objects carry radioactive contaminants.

[0003] In existing technologies, some safety detection devices for radioactive contamination of gantry structures continuously collect radiation signals within the gantry when personnel or objects pass through the gantry passage.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Safety detection device for radioactive contamination of gantry, refer to Figures 2 to 4 The device includes a base plate 1 and a top plate 3. The base plate 1 serves as the bottom support component of the entire device. The top plate 3 contains a radiation detection component. A rotating mechanism 4 is fixedly connected to the bottom of the top plate 3. The rotating mechanism 4 is the core power and transmission mechanism that drives the camera 5 to rotate at multiple angles. The camera 5 is fixedly connected to the bottom of the rotating mechanism 4. Its main function is to collect image information of people and objects in the detection channel in real time. A telescopic mechanism 6 is fixedly connected to the top of the top plate 3. The telescopic mechanism 6 is the key mechanism for realizing the top protection of the device.

[0041] The rotating mechanism 4 includes a motor 41, the top of which is fixedly connected to the bottom of the top plate 3. The motor 41 serves as the power source for the rotating mechanism 4. A drive shaft 42 is fixedly connected to the drive end of the motor 41, which transmits the rotational power output by the motor 41 to the subsequent fixed block 43 and gear set. A fixed block 43 is fixedly connected to the outside of the drive shaft 42. The fixed block 43 is an intermediate component connecting the drive shaft 42 and the first rotating shaft 44. The first rotating shaft 44 is rotatably connected inside the fixed block 43. The first rotating shaft 44 is the core shaft component of the gear transmission in the rotating mechanism 4. Gear 45 is fixedly connected to the outside of the rotating mechanism 4. Gear 45 is one of the driving gears of the gear transmission system of the rotating mechanism 4. Gear 46 is fixedly connected to the outside of the rotating shaft 44. Gear 46 is also a driving gear of the gear transmission system of the rotating mechanism 4. Rotating shaft 47 is rotatably connected to the top of the camera 5. Rotating shaft 47 is a shaft component that directly drives the camera 5 to rotate. Gear 48 is fixedly connected to the outside of the rotating shaft 47. Gear 49 is fixedly connected to the outside of the rotating shaft 47. It meshes with gear 46 to drive the camera 5 to rotate.

[0042] Rotating assemblies 410 are fixedly connected to both the left and right sides of the motor 41, providing support and limiting for the motor 41 and surrounding transmission components. Each rotating assembly 410 includes a fixing plate 4101. The right side of the fixing plate 4101 is fixedly connected to the left side of the motor 41, providing stable mounting support for the drive shaft 4102. The right side of the fixing plate 4101 is rotatably connected to the drive shaft 4102, adjusting the position of the transmission frame 4103 through its rotation. The right side of the drive shaft 4102 is rotatably connected to the transmission frame 4103, which controls the movement of the drive shaft 4102. The direction of movement plays a certain role in limiting and guiding. The external rotatable connection of the transmission frame 4103 is the transmission shaft 4104, which plays a role in buffering and shock absorption. The external of gear 1 45 is meshed with the external of gear 3 48, and the external of gear 2 46 is meshed with the external of gear 49. This makes the rotation shaft 2 47 more evenly stressed and rotate more smoothly under the synchronous drive of the gears on both sides, effectively avoiding the problems of insufficient power and unstable transmission. This ensures that the camera 5 can flexibly and accurately achieve multi-angle rotation to meet the image acquisition requirements during the detection process.

[0043] Specifically, the base plate 1 has a stabilizing device, the top plate 3 has a radiation detection component and connects the rotating mechanism 4 and the telescopic mechanism 6, the motor 41 drives the drive shaft 42 and the fixed block 43 to rotate, the gear 45 outside the rotating shaft 44 drives the rotating shaft 47 and the gear 48 to rotate, the rotating component 410 stabilizes and reduces shock, so that the camera 5 can flexibly and accurately capture images from multiple angles, the overall movement is stable, and the detection and image acquisition are efficient.

[0044] Reference Figure 1 and Figure 2The telescopic mechanism 6 includes a cylinder 61, the bottom of which is located on the top of the top plate 3. Through the telescopic movement of its own drive end, it provides power for the subsequent movement of the slider plate 62. The drive end of the cylinder 61 is fixedly connected to the slider plate 62, converting the linear telescopic motion of the cylinder 61 into power to drive the synchronous movement of the two fixed seats 63. Fixed seats 63 are fixedly connected to the left and right sides of the slider plate 62. The fixed seats 63 are intermediate connecting parts between the slider plate 62 and the transmission assembly 64. The top of the fixed seats 63 is rotatably connected to the transmission assembly 64. The transmission assembly 64 is the core transmission component in the telescopic mechanism 6 that realizes the height and horizontal position adjustment of the canopy 66. The transmission assembly 64 includes a transmission plate 641, the bottom of which is rotatably connected to the top of the fixed seat 63. A transmission shaft is rotatably connected inside the transmission plate 641. 642 provides a pivot point for the second transmission plate 643. The third transmission shaft 642 is rotatably connected to the second transmission plate 643, which receives the power transmitted by the first transmission plate 641. The top of the second transmission plate 643 is fixedly connected to the second fixing plate 65, which provides a stable mounting base for one side of the canopy 66. The top of the second fixing plate 65 is fixedly connected to the canopy 66, which covers the area of ​​the top plate 3 of the device when unfolded. The rear side of the canopy 66 is rotatably connected to the winding shaft 67, which mainly functions to wind the retracted canopy 66 around the shaft body through its own rotation. The left and right sides of the winding shaft 67 are fixedly connected to the second fixing seat 68 to ensure that the winding shaft 67 will not axially deviate or shake during rotation, thus ensuring the stability of the canopy 66 during storage and release. At the same time, the second fixing seat 68 can also protect the winding shaft 67 and extend its service life.

[0045] Specifically, cylinder 61 drives slider 62 to move fixed seat 63. Through transmission assembly 64, transmission plate 641, transmission shaft 642, and transmission plate 643 transmit force to fixed plate 65, realizing the extension and retraction of awning 66. Fixed seat 68 stabilizes the roller 67 to prevent deviation, making the extension and retraction of awning 66 smooth, providing coverage and protection, ensuring durable components, and guaranteeing stable and efficient telescopic function.

[0046] Reference Figure 2 Support plates 2 are fixedly connected to both sides of the base plate 1. The support plates 2 contain radiation detection components to detect radioactive radiation. A display screen 7 is fixedly connected to the front of the top plate 3 to display key data in real time during the detection process. An alarm light 8 is fixedly connected to the front of the top plate 3 to flash light at high frequency when radioactive radiation exceeds the standard. The bottom of the second fixing seat 68 is fixedly connected to the top of the top plate 3 to provide a more reliable installation base for the winding shaft 67. The bottom of the first fixing seat 63 is fixedly connected to the top of the top plate 3. The fixed connection between the bottom and the top plate 3 restricts it to move only along a preset trajectory on the surface of the top plate 3, preventing the first fixing seat 63 from shaking up and down or shifting during movement.

[0047] Specifically, the support plate 2 is equipped with a radiation detection component that can accurately detect radiation. The display screen 7 displays data in real time, and the alarm light 8 flashes when the radiation exceeds the standard, which facilitates timely handling. The second fixed seat 68 stabilizes the winding shaft 67, and the first fixed seat 63 limits the trajectory to prevent shaking. Together with the cylinder 61, the sliding plate 62 drives the transmission component 64 to make the canopy 66 unfold and retract smoothly. The overall structure is stable, ensuring the stable outdoor operation of the device.

[0048] The implementation principle of this application embodiment is as follows: When the start motor 41 rotates the fixed block 43 and the rotating shaft 44, the gears 45 and 48 rotate, and the connected camera 5 rotates when the gears 46 and 49 rotate. Under the rotational connection of the fixed plate 4101 and the transmission shaft 4102, the transmission frame 4103 and the transmission shaft 4104 rotate the camera 5 better, increasing stability. This enables the camera 5 to rotate to accurately locate the radioactive radiation and cover most of the area.

[0049] When the starting cylinder 61 drives the slider plate 62 to slide in the top groove of the top plate 3, the transmission component 64 is fixed to the front side of the top plate 3 by the fixing seat 63. The sliding drives the transmission plate 641 to rotate under the transmission shaft 642, so that the fixing plate 65 and the canopy 66 slide. When the canopy 66 is slid by the winding shaft 67, the canopy 66 is evenly wound around the outside of the winding shaft 67, so as to realize the orderly storage of the canopy 66 and ensure that the entire telescopic sliding process is stable and smooth.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
