Detailed Implementation

[0032] 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.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figure 1 This utility model discloses a laser decontamination robot for nuclear power plants, comprising a processing box 1. A robotic arm 7 is fixedly connected to the inner wall of the rear end of the processing box 1, and is securely connected to the robotic arm 7 by a specific fixing method. This robotic arm plays a key role in the entire decontamination operation. It can flexibly adjust its position and angle to adapt to the decontamination requirements of different nuclear power components. There is a drain pipe at the rear end of the processing box 1, controlled by a control valve. A support column 8 is fixedly connected to the inner wall of the bottom of the processing box 1, and a fixed plate 10 is fixedly connected to the top of the support column 8. The parameters of the robotic arm 7 are: laser power 2000W, wavelength 1060 nm, pulse frequency 1000 Hz, scanning speed 100 mm / s-500 mm / s, and nuclear power environment (low protection).

[0035] Reference Figure 3 and Figure 4A motor 9 is fixedly connected to the inner wall of the bottom of the processing box 1. A gear 11 is fixedly connected to the output end of the motor 9. After the motor starts, it can drive the gear 11 to rotate. The inner walls of the left and right sides of the fixed disk 10 are provided with first sliding grooves 18. The inner walls of the first sliding grooves 18 are slidably connected to first sliders 19. One end of the first slider 19 is fixedly connected to a rack 17, and the rack 17 is meshed with the gear 11. Since the rack 17 and the gear 11 are meshed with each other, when the gear 11 rotates under the drive of the motor 9, it will drive the rack 17 to move in a straight line in the diagonal direction of the fixed disk 10. A connecting block 20 is fixedly connected to the top of the rack 17. A uniformly distributed guide block 12 is fixedly connected to the top of the fixed disk 10. A moving block 13 is slidably connected to the outer wall of the guide block 12. A clamping plate 14 is fixedly connected to the top of the moving block 13, and the clamping plate 14 is fixedly connected to the connecting block 20, so that the moving block 13 can move smoothly along the direction determined by the guide block 12. The top of the movable block 13 is fixedly connected to the clamping plate 14, and the clamping plate 14 is fixedly connected to the connecting block 20. In this way, when the rack 17 moves, it will drive the clamping plate 14 to move along the guiding direction of the guide block 12 through the connecting block 20. Springs 15 are fixedly connected to the inner walls of opposite sides of the clamping plate 14. A sliding rod 16 is fixedly connected to one end of the spring 15. When the clamping plate 14 clamps the nuclear power components, the springs 15 and the sliding rod 16 can play a buffering role to avoid damage to the components due to excessive clamping force. At the same time, it can also ensure that appropriate clamping force can be provided during the clamping process of components of different shapes and sizes.

[0036] Reference Figure 2 , Figure 5 and Figure 6The processing box 1 has a cleaning assembly inside on its right side, including a filter box 2. The filter box 2 is fixedly connected to the inner wall of the right side of the processing box 1. Second sliding grooves 21 are provided on both the upper and lower inner walls of the filter box 2. A cover plate 3 is installed on the top of the processing box 1, and a water tank 4 is fixedly connected to the top of the cover plate 3. A connecting pipe 30 is fixedly connected to the outlet of the water tank 4. The cover plate 3 not only provides protection but also provides a mounting base for other components. The water tank 4 is fixedly connected to the top of the cover plate 3 and is used to store the liquid required for cleaning. The outlet of the water tank 4 is fixedly connected to the connecting pipe 30 to transport the liquid in the tank to a designated location. At the bottom center of the cover plate 3, an electric slide rail 28 is fixedly connected to provide power support for the movement of the connecting pipe 30. A second slider 22 is slidably connected to the inner wall of the second slide groove 21. A connecting frame 23 is fixedly connected between the second sliders 22. A high-efficiency air filter plate 24 is fixedly connected to the left side of the connecting frame 23, and an activated carbon plate 27 is fixedly connected to the right side. The filter plate effectively filters out fine particles and impurities in the air, ensuring that the air entering the processing chamber meets certain cleanliness standards. An activated carbon plate 27 is fixedly connected to the right side of the connecting frame 23. The activated carbon plate adsorbs harmful gases and odors in the air, further improving air cleanliness. An exhaust fan 5 is fixedly connected to the right side of the filter box 2, and an air outlet box 6 is fixedly connected to the right side of the exhaust fan 5. The exhaust fan 5 generates strong suction to draw air out of the processing chamber and purify it by passing it through the high-efficiency air filter plate 24 and the activated carbon plate 27. After purification, the air enters the exhaust box 6 from the right side of the exhaust fan 5 and is finally discharged into the external environment. The front left and right sides of the filter box 2 are fixedly connected to the fixing plates 25, and the fixing plates 25 are threaded with bolts 26. By tightening and loosening the bolts 26, the filter box 2 can be easily disassembled and installed, which facilitates the maintenance and replacement of internal filter plates and other components. The outer wall of the electric slide rail 28 is slidably connected to the sliding block 29, and the sliding block 29 is fixedly connected to the outer wall of the connecting pipe 30. When the electric slide rail 28 is started, it can drive the sliding block 29 and the connected pipe 30 to move at the bottom of the cover plate 3, thereby realizing the spraying of liquid at different positions in the processing box to assist in the cleaning work.

[0037] Working principle: After the motor 9 starts, its output end drives the gear 11 to rotate. Since the gear 11 meshes with the rack 17, and the rack 17 slides and is limited within the first groove 18 of the fixed plate 10 through the first slider 19, the rotation of the gear 11 causes the rack 17 to perform linear reciprocating motion. The connecting block 20 at the top of the rack 17 moves together with the rack 17, thereby driving the clamping plate 14, which is fixedly connected to the connecting block 20, to move. The springs 15 and sliding rods 16 on the inner walls of the clamping plates 14 provide cushioning and auxiliary fixation, ensuring that the workpiece to be cleaned placed between the clamping plates 14 is stably clamped and its position is adjusted according to the drive of the motor 9, facilitating subsequent laser cleaning operations. Cleaning is performed by the robotic arm 7. Water from the water tank 4 on the top cover plate 3 of the processing box 1 flows out through the connecting pipe 30. The connecting pipe 30 adjusts the water spray position by sliding the sliding block 29 on the electric slide rail 28, assisting the cleaning process, such as cooling and rinsing. The exhaust fan 5 is activated, drawing air from the processing box 1 into the filter box 2. In the filter box 2, the air first undergoes preliminary filtration through the high-efficiency air filter plate 24 on the left side of the connecting frame 23, removing most of the impurities. Then, it passes through the activated carbon plate 27 on the right side of the connecting frame 23 to further adsorb harmful gases and odors. The purified air is then discharged from the exhaust box 6, ensuring the air quality inside the processing box 1 and preventing environmental pollution and harm to operators.
