[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 5 As shown, a cyclotron shielding device according to an embodiment of the present invention includes a base plate 1, a shielding mechanism on the top of the base plate 1, and the shielding mechanism including: a shielding component, including a fixed shell 2 fixedly connected to one side of the top of the base plate 1, a first rectangular plate 3 fixedly connected to both sides of the fixed shell 2, a pair of rectangular grooves 4 opened on the first rectangular plate 3, a locking through groove 5 opened on the groove wall of the rectangular groove 4, a pair of grooves 6 opened on the base plate 1, a slide rail 7 fixedly connected in the groove 6, a sliding block 8 slidably connected on the slide rail 7, a movable shell 9 fixedly connected to the top of the pair of sliding blocks 8, and a fastening component provided on the movable shell 9; a moving component, provided on the side wall of the movable shell 9 for moving the movable shell 9; and a cleaning component, provided on the side wall of the movable shell 9 for cleaning debris.

[0029] During operation, the fastening components can be inserted into the slot 5 to assist in fastening and prevent movement during vibration, thus avoiding gaps. This solves the problem in the prior art where the shield may loosen the connecting parts under vibration, resulting in gaps between the shields, affecting the sealing effect and causing radiation leakage.

[0030] The fastening assembly includes a pair of second rectangular plates 10 fixed to both sides of the movable housing 9, a hydraulic rod 11 fixed to the side wall of the second rectangular plate 10, and a rectangular block 12 fixed to the telescopic end of the hydraulic rod 11.

[0031] The rectangular block 12 has a sliding groove 13 on its side wall. The bottom of the sliding groove 13 is connected to a locking block 14 by a spring, and the locking block 14 is slidably connected in the sliding groove 13. The side of the locking block 14 located outside the sliding groove 13 is an inclined surface.

[0032] During operation, the hydraulic rod 11 can drive the rectangular block 12 to move, and the locking block 14 can be inserted into the locking slot 5 under the elastic force of the spring. This allows the hydraulic rod 11 to pull the moving shell 9 to move when it retracts at the retracted end. Under the action of the hydraulic rod 11, the moving shell 9 is fastened to the fixed shell 2, which plays an auxiliary role, improves tightness, and prevents movement and gaps during vibration.

[0033] A pair of electric actuators 15 are fixedly connected to both sides of the fixed housing 2. A support plate 16 is fixedly connected to the telescopic end of the pair of electric actuators 15. A top block 17 is fixedly connected to the side of the support plate 16 near the electric actuators 15.

[0034] During operation, the electric push rod 15 can be used to move the support block when the movable shell 9 needs to be opened, so that the top block 17 can be inserted into the locking slot 5, pushing out the locking block 14 and releasing the locking block 14.

[0035] The moving assembly includes a pair of toothed plates 18 fixed to the top of the base plate 1, and a pair of first fixing blocks 19 fixed to the side wall of the moving shell 9. A rotating rod 20 is rotatably connected to the pair of first fixing blocks 19 through a rotating hole. Gears 21 are fixed to both ends of the rotating rod 20, and the gears 21 mesh with the toothed plates 18.

[0036] A servo motor 22 is fixedly connected to the side wall of the movable shell 9 via a second fixing block. The output end of the servo motor 22 is provided with a drive rod 23, and the end of the drive rod 23 away from the servo motor 22 is fixedly connected to a first synchronous wheel 24.

[0037] A second synchronous pulley 25 is fixedly connected to the rotating rod 20, and the first synchronous pulley 24 and the second synchronous pulley 25 are connected by a synchronous belt 26.

[0038] During operation, the servo motor 22 drives the drive rod 23 to rotate, which in turn drives the first synchronous wheel 24 to rotate. The first synchronous wheel 24, the synchronous belt 26, and the second synchronous wheel 25 drive the rotating rod 20 to rotate, which in turn drives the moving shell 9 to move through the gear 21 that meshes with the toothed plate 18. This allows the moving shell 9 and the fixed shell 2 to merge and close together. At the same time as merging, the locking block 14 can automatically lock into the locking slot. The moving components prevent the moving shell 9 from being too heavy and difficult to move.

[0039] The cleaning assembly includes a pair of fixed rods 27 fixed to the side wall of the movable housing 9, a cleaning plate 28 fixed to the bottom of the pair of fixed rods 27, and a set of brushes 29 provided at the bottom of the cleaning plate 28.

[0040] During operation, the brush 29 can clean the slide rail 7 and toothed plate 18, allowing the movable shell 9 to move normally. This prevents debris from accumulating on the slide rail 7 and toothed plate 18. If not cleaned for a long time, it can easily cause wear and tear, making it difficult for the movable shell 9 and fixed shell 2 to fit together tightly, thus affecting the shielding effect.

[0041] Working principle: The fastening components can be inserted into the slot 5 to assist in fastening and prevent movement during vibration, thus avoiding gaps. This solves the problem in the prior art where the shield may loosen the connecting parts under vibration, resulting in gaps between the shields, affecting the sealing effect and causing radiation leakage.

[0042] The hydraulic rod 11 can drive the rectangular block 12 to move, and the locking block 14 can be inserted into the locking slot 5 under the elastic force of the spring. This allows the hydraulic rod 11 to pull the moving shell 9 to move when it retracts at the retracted end. Under the action of the hydraulic rod 11, the moving shell 9 is fastened to the fixed shell 2, which plays an auxiliary role, improves tightness, and prevents movement and gaps during vibration.

[0043] When the movable housing 9 needs to be opened, the electric push rod 15 can drive the support block to move, so that the top block 17 can be inserted into the locking slot 5, pushing out the locking block 14 and releasing the locking block 14.

[0044] The servo motor 22 drives the drive rod 23 to rotate, which in turn drives the first synchronous wheel 24 to rotate. The first synchronous wheel 24, the synchronous belt 26, and the second synchronous wheel 25 drive the rotating rod 20 to rotate. The gear 21, which meshes with the toothed plate 18, pushes the moving shell 9 to move, so that the moving shell 9 and the fixed shell 2 can be merged and closed. At the same time as merging, the locking block 14 can automatically lock into the locking groove. The moving components can prevent the moving shell 9 from being too heavy and difficult to move.

[0045] The brush 29 can clean the slide rail 7 and toothed plate 18, allowing the movable shell 9 to move normally. It also prevents debris from accumulating on the slide rail 7 and toothed plate 18. If debris is not cleaned for a long time, it can easily cause wear and tear, making it difficult for the movable shell 9 and the fixed shell 2 to fit together tightly, thus affecting the shielding effect.
