Description

Technical Field

[0001] The utility model relates to the field of patrol inspection and camera inspection, in particular to an accelerator maze patrol inspection and camera inspection device. Background Art

[0002] As a type of particle accelerator, a proton accelerator accelerates protons to near the speed of light through electric and magnetic fields, generating high-energy proton beams. These beams have a wide range of applications in medicine, scientific research, and industry, including proton cancer therapy, material modification, and irradiation processing. Proton accelerators generate intense radiation during operation, making real-time monitoring and inspection of the operating environment crucial to ensure personnel safety and proper equipment operation.

[0003] Accelerator mazes, an essential component of the proton accelerator's working environment, serve as pathways connecting the various functional areas of the accelerator. These mazes are typically complex in design, with multiple branches and turns to effectively connect these different functional areas.

[0004] During proton accelerator operation, radiation doses are high, and workers are prohibited from entering the accelerator hall. Instead, they rely on cameras to monitor safety issues during accelerator operation and to detect any personnel remaining within the hallway, potentially causing radiation accidents. This type of inspection camera system, typically equipped with high-definition cameras and a mobile platform, enables comprehensive, comprehensive monitoring and filming within the maze. By transmitting inspection images in real time, workers can remotely monitor and analyze the status of the accelerator maze from a safe location, enabling them to promptly identify and address potential safety hazards.

[0005] During the operation of the proton accelerator, ordinary cameras will be exposed to excessive radiation, which greatly reduces their service life. The fixed radiation-proof cameras on the market are extremely expensive, and the field of view of each camera is limited, so they cannot observe the entire maze and the entire accelerator operation position.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] See also Figure 1-8The present invention provides an embodiment of an accelerator maze inspection camera device, comprising an inspection camera device 6, which is set based on the accelerator inspection track 1, and the layout trajectory of the inspection track 1 is referenced Figure 8 set up, Figure 1-7 The inspection track 1 is shown only partially. The inspection track 1 consists of an upper mounting plate 2, a vertical fixing plate 3, an outer limit frame 4, and a fixed rack 5. The vertical fixing plates 3 are fixed to both ends of the lower end of the upper mounting plate 2, while the outer limit frames 4 are fixed to the lower ends of the front and rear ends of the vertical fixing plate 3. A fixed rack 5 is welded to the upper end of the inner end of the vertical fixing plate 3, which meshes with the drive gear in the inspection camera 6.

[0033] An upper limit sliding frame 8 is fixed to the front and rear ends of the lead protective housing 7 of the inspection camera 6, corresponding to the outer limit frame 4. This frame mates with the outer limit frame 4 and slides along it. Simultaneously, the lower end of the upper limit sliding frame 8 is rotatably connected to movable rollers 9, which roll smoothly along the outer limit frame 4, thereby ensuring that the inspection camera 6 can move flexibly along the inspection track 1.

[0034] A first drive motor 10 is installed on one side of the upper end of the lead protective shell 7, and a first bevel gear 11 is installed on the output shaft end of the motor. The outer side of the upper end of the first bevel gear 11 is meshed with the second bevel gear 12. A first drive gear 13 is installed along the upper end of the second bevel gear 12 on the upper end of the lead protective shell 7, and the gear is coaxially connected to the second bevel gear 12. At the same time, a second drive gear 14 is also installed along one end of the first drive gear 13 on the upper end of the lead protective shell 7, and the gear is meshed with the first drive gear 13. The second drive gear 14 and the first drive gear 13 are respectively meshed with the two fixed racks 5, thereby realizing the smooth movement of the inspection camera device 6 along the inspection track 1.

[0035] A patrol camera 26 is also installed inside the lead protective shell 7. The camera can perform patrol inspections and video recordings through the highly transparent lead glass 31 installed at the lower end of the lead protective shell 7. This design ensures that the patrol camera 26 can clearly capture images inside the maze while avoiding interference from radiation on the camera.

[0036] In order to further improve the flexibility and stability of the inspection camera device 6, an upper fixed plate 15 and a lower fixed plate 27 are fixed in the middle of the lead protective shell 7. An upper closed cavity 29 is formed between the two fixed plates, and a lower inspection camera cavity 30 is formed at the lower end of the lower fixed plate 27. A lower lifting assembly 20 is arranged inside the upper closed cavity 29. The assembly includes an upper plate 21, a lower plate 23 and a connecting frame 22. The inspection camera 26 is connected to the upper plate 21 by a connecting bracket 25. This design not only improves the stability and shooting effect of the inspection camera 26, but also makes the structure of the entire inspection camera device 6 more compact and reasonable. Among them, the shape and size of the upper plate 21 and the lower plate 23 match the rectangular through-groove 28 opened inside the lower fixed plate 27. In the non-working state, the lower lifting assembly 20 is located in the upper closed cavity 29, and the lower plate 23 is stuck in the rectangular through groove 28, so as to better protect the inspection camera 26; in the working state, the lower lifting assembly 20 enters the lower inspection camera cavity 30, and the upper plate 21 is stuck in the rectangular through groove 28, and the inspection camera 26 in the lower lifting assembly 20 performs inspection and video recording through the high-transmittance lead glass 31.

[0037] In order to achieve smooth lifting and lowering of the lower lifting assembly 20, a second drive motor 16 is installed on one side of the upper end of the upper fixed plate 15. The output shaft end of the motor is connected to the third bevel gear 17, and the upper end of the upper fixed plate 15 is centrally connected to the fourth bevel gear 18. The fourth bevel gear 18 is meshed with the third bevel gear 17, and its internal thread is connected to a threaded rod 19. The threaded rod 19 passes through the hole in the upper fixed plate 15 and is rotatably connected to the upper plate 21 via a bearing. The upper end of the upper plate 21 is also fixed with limit rods 24 along the front and rear ends of the threaded rod 19. These rods slide along the upper fixed plate 15 to ensure the stability and accuracy of the lower lifting assembly 20 during the lifting process.

[0038] In order to facilitate the staff to carry out inspection and maintenance, the lead protection shell 7 end surface along the upper closed cavity 29 and the lower inspection camera cavity 30 are all installed with lead inspection doors 32. The design of these inspection doors enables the staff to easily perform various operations on the internal components of the inspection camera device 6.

[0039] Working principle: The first drive motor 10 drives the first bevel gear 11 to rotate, and drives the first drive gear 13 to rotate through the meshing connection relationship between the first bevel gear 11 and the second bevel gear 12. The second drive gear 14 rotates synchronously with the first drive gear 13 in the opposite direction through the meshing connection relationship with the first drive gear 13. Since the second drive gear 14 and the first drive gear 13 are respectively meshed with two fixed racks 5, and the fixed racks 5 are fixed on the inspection track 1, the rotation of the second drive gear 14 and the first drive gear 13 drives the entire inspection camera device 6 to move along the laid inspection track 1.

[0040] In the non-operating state, the lower lifting assembly 20 is located in the upper closed cavity 29, and the lower plate 23 is stuck in the rectangular through-groove 28, which better protects the inspection camera 26. In the operating state, the second drive motor 16 drives the third bevel gear 17 to rotate, and the fourth bevel gear 18 rotates due to the meshing connection between the third bevel gear 17 and the fourth bevel gear 18. Due to the threaded connection between the threaded rod 19 and the fourth bevel gear 18, and the bearing connection between the fourth bevel gear 18 and the upper fixed plate 15, the threaded rod 19 rotates downward, driving the lower lifting assembly 20 downward, so that the lower lifting assembly 20 enters the lower inspection camera cavity 30, and the upper plate 21 is stuck in the rectangular through-groove 28; the inspection camera 26 in the lower lifting assembly 20 performs inspection and video recording through the high-transmittance lead glass 31.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
