Description

Technical Field

[0001] The present application relates to the technical field of nuclear radiation protection, and in particular to a movable nuclear radiation protection window. Background Art

[0002] Nuclear radiation protection windows are a type of safety equipment commonly used in hospital radiology departments, chemical plants, and other facilities that require protection from nuclear radiation. The main function of this type of protection window is to allow workers to safely observe the internal situation without being exposed to the radioactive environment, thereby effectively monitoring and managing it. At present, nuclear radiation protection windows generally adopt a fixed design and are embedded in a wall with radiation protection capabilities to ensure a seamless connection between the window and the wall to prevent nuclear radiation leakage.

[0003] Nuclear radiation protection windows usually use specially made radiation-proof glass, which can effectively filter and reduce the transmission of nuclear radiation. However, although this high-density radiation-proof glass performs well under normal circumstances, its protective effect may be insufficient in extreme cases where nuclear radiation is drastically enhanced. This shows that although existing protective window technology provides visual access and a certain degree of protection for internal operations, there is still room for improvement and innovation.

[0004] In addition, current nuclear radiation protection measures also include the use of large opening and closing radiation-resistant doors to achieve the transfer and ventilation of items. These doors are usually designed to be quite thick to ensure that they can prevent radiation leakage when closed. However, every time the door needs to be opened to transfer items or perform other operations, even if the time is short, the risk of nuclear radiation leakage still increases significantly. Each opening and closing operation not only increases the potential leakage of nuclear radiation, but also affects work efficiency.

[0005] Based on this, those skilled in the art have proposed a mobile nuclear radiation protection window. Summary of the invention

[0020] Compared with the prior art, the beneficial effects of this application are:

[0021] 1. Through the first driving source, the rotating shaft is started to drive the driving gear to rotate. The rotation of the driving gear further prompts the fixed tooth plate to move, thereby pushing the rectangular plate to move accordingly. As the rectangular plate moves, the adjusting plate also moves and adjusts the angle accordingly. The movement of the adjusting plate drives the sliding block to move up and down in the adjusting groove to change the height through the connecting rod mechanism, thereby realizing the precise blocking of the window. In this way, the adjusting plate and the blocking block work together to effectively block the leakage of nuclear radiation. Reverse activation of the first driving source can make the blocking block withdraw and realize the opening of the window. Through such a setting, the device can be completely closed when necessary, thereby avoiding a large amount of nuclear radiation leakage and causing safety hazards to the staff;

[0022] 2. By activating the second driving source to lower the moving tooth plate, this action causes the driving end to rotate. This rotation is transmitted to the driving gear through the driving rod, so that it meshes with the teeth in the arc groove and rotates. This series of actions drives the matching gear and the driven gear to rotate, thereby driving the rotating rod. Since the meshing rotation direction is opposite, the movement of the rotating rod and the driving rod is in an unfolded state, so that the protective glass is pushed to the window, thereby achieving shielding. In this way, the staff can not only safely observe the interior through the window, but also the existence of the protective glass significantly reduces the potential harm of nuclear radiation to the human body;

[0023] 3. The blocking mechanism enables the device to be completely closed when necessary, thereby minimizing the risk of nuclear radiation leakage. At the same time, the adjustment mechanism provides the device with a visual observation function, which is convenient for operators to observe and operate from a safe area. Both the blocking and adjustment mechanisms are designed to be deployable, so that the window cover can be connected to the outside world when not in operation, which is convenient for operators to pass items or circulate air through the window. Compared with traditional fixed windows, this device provides the same functional effect, but is more flexible in use and can be adjusted according to different application scenarios, showing higher practicality and adaptability.

[0035] Example 1

[0036] like Figure 1-Figure 7 As shown, the present invention provides a movable nuclear radiation protection window: comprising a window cover 1, and also comprising:

[0037] A blocking mechanism is arranged on one side of the window cover 1, and the blocking mechanism controls the opening and closing of the protective window by driving the blocking end to move;

[0038] The blocking mechanism includes a limit frame 2, an adjustment frame 4, and a rectangular plate 7. The limit frame 2 is symmetrically fixedly connected to one side of the window cover 1. The limit frame 2 is provided with a limit groove 3 inside. The adjustment frame 4 is fixedly connected to one side of the window cover 1 and is located on the side where the two limit frames 2 are close to each other. The adjustment frame 4 is provided with an adjustment groove 5 inside. The adjustment groove 5 is set to an L-shaped structure. The inside of the adjustment groove 5 is slidably connected with a sliding seat 6. The sliding seat 6 can move in position inside the adjustment groove 5 and can be adjusted in height through the L-shaped adjustment groove 5. In this way, the blocking end can be controlled to perform blocking work, thereby achieving a closing effect.

[0039] The rectangular plate 7 is arranged on one side of the window cover 1 and between the two sliding seats 6. The four corners of the top of the rectangular plate 7 are fixedly connected with connecting blocks 8. The sides away from the two connecting blocks 8 are fixedly connected with connecting rods 9. The inside of the limiting groove 3 is symmetrically slidably connected with four moving seats 10. The ends of the connecting rods 9 away from the corresponding connecting blocks 8 are fixedly connected with the corresponding moving seats 10. The connecting blocks 8 and the connecting rods 9 can keep the rectangular block 7 at a fixed height for movement. Such an arrangement is conducive to the control of the thickness of the overall structure of the window cover 1.

[0040] The blocking mechanism also includes a fixed tooth plate 12, a rotating shaft 14, a driving gear 15 and a first driving source 16. The top of the rectangular plate 7 is symmetrically fixedly connected to two fixed rods 11, the fixed tooth plate 12 is fixedly connected between the tops of the two fixed rods 11, the top of the window cover 1 and located on the outside of the two limit frames 2 are symmetrically fixedly connected to two vertical plates 13, the rotating shaft 14 is rotatably connected between the two vertical plates 13, the driving gear 15 is fixedly connected to the rotating shaft 14, the driving gear 15 is meshed with the fixed tooth plate 12, the first driving source 16 is fixedly connected to the outside of one of the vertical plates 13 and its output end is fixedly connected to one end of the rotating shaft 14, the rotating shaft 14 is driven to rotate by the first driving source 16, and the driving gear 15 is driven to rotate by the rotating shaft 14, so that the fixed tooth plate 12 is driven to move by the rotation of the driving gear 15, so that the motion state of the rectangular plate 7 can be controlled;

[0041] The blocking mechanism also includes a fixed plate 17, a connecting shaft 18, a connecting rod 19, an adjusting plate 20, a blocking block 21 and a window 22. The fixed plate 17 is fixedly connected to the bottom of the rectangular plate 7 at an equal distance. The connecting shaft 18 is fixedly connected between the corresponding two fixed plates 17. Both ends of one of the connecting shafts 18 are fixedly connected to one side of the corresponding sliding seat 6. The connecting rods 19 are symmetrically structured and rotatably connected to the outside of the connecting shaft 18 and are located on the outside of the two fixed plates 17. The adjusting plate 20 is rotatably connected between the bottoms of the four connecting rods 19. The blocking block 21 is fixedly connected to the bottom of the adjusting plate 20. The window 22 is opened on the window cover 1. The blocking block 21 is connected to the window cover 1. The window 22 is used in conjunction with the adjusting plate 20. The size of the window 22 is smaller than that of the window 22, and the size of the adjusting plate 20 is larger than that of the window 22. When the rectangular plate 7 moves, the adjusting plate 20 will also move with it. When the adjusting plate 20 moves, it will drive the sliding block 6 to move. The sliding block 6 will change in height due to the shape of the adjusting groove 5. Because the adjusting plate 20 has the connecting rod 19, the entire adjusting plate 20 can cooperate with the sliding block 6 for angle adjustment, so that the blocking block 21 can slide into the window 22. In this way, the adjusting plate 20 and the blocking block 21 can be used to block the window 22, thereby achieving the purpose of preventing nuclear radiation leakage.

[0042] Example 2

[0043] like Figure 1-Figure 7 As shown, the present invention also provides a movable nuclear radiation protection window: comprising a window cover 1, and also comprising:

[0044] An adjusting mechanism is used to drive the visible glass to move, and realize the visual effect and the radiation protection effect at the same time by the movement of the glass. A groove body 26 is provided inside the window cover 1, and a protective glass 27 is slidably connected inside the groove body 26. The size of the protective glass 27 is larger than the window 22, and the protective glass 27 is set as a radiation protection glass. The adjusting mechanism includes a driving rod 28, a positioning rod 30, a moving tooth plate 31, and a second driving source 32. A driving end 29 is provided at one end of the driving rod 28. The positioning rod 30 is fixedly connected to the groove body 26, and the moving tooth plate 31 is slidably connected to the outer side of the positioning rod 30. The moving tooth plate 31 is meshed and connected with the driving end 29. The second driving source 32 is fixedly connected to the inside of the groove body 26, and the output end of the second driving source 32 is fixedly connected to the moving tooth plate 31. The movement of the second driving source 32 can drive the moving tooth plate 31 to descend, and the descending of the moving tooth plate 31 can drive the driving end 29 to rotate, and then the rotation of the driving end 29 drives the driving rod 28 to rotate;

[0045] The adjusting mechanism includes a driving gear 23, a rotating rod 24, a driven gear 25 and a matching gear 36. A notch 35 is provided at one end of the driving rod 28. The matching gear 36 is rotatably connected to the inside of the notch 35 through the rod body. The rotating rod 24 is rotatably connected to the inside of the notch 35. The other end of the rotating rod 24 is rotatably connected to one end of the protective glass 27. The driven gear 25 is fixedly connected to the rotating rod 24. The driven gear 25 is meshed with the matching gear 36. Both sides of the driving rod 28 are connected to the driving gear 23. The driving gear 23 rotates coaxially with the matching gear 36. The adjusting mechanism also includes an arc groove 33 and teeth 34. The arc groove 33 is provided on both sides of the groove body 26. The arc groove 33 is set to a quarter-circular structure. The teeth 34 are equidistantly provided on the inner wall of the arc groove 33. The driving gears 23 extend to the inner wall of the corresponding arc groove 33. The driving rod 28 is meshed with the teeth 34 and connected thereto. When the driving rod 28 rotates, the driving gear 23 can be driven to rotate. At the same time, because the driving gear 23 is meshed with the teeth 34 in the arc groove 33, the driving gear 23 will rotate, thereby driving the matching gear 36 to rotate. The driven gear 25 is driven to rotate by the rotation of the matching gear 36, so that the rotating rod 24 can be rotated. Because the rotation directions of the meshing are opposite, the rotation direction of the rotating rod 24 is opposite to the rotation direction of the driving rod 28. Therefore, the rotating rod 24 and the driving rod 28 can move in an unfolded state, thereby realizing the shielding glass 27 being pushed into the window 22 for shielding effect. Conversely, the shielding glass 27 can be pulled out of the window 22. In this way, the rotating rod 24 and the driving rod 28 can be folded, and the storage of the shielding glass 27 will not be affected.

[0046] Working principle:

[0047] In actual use, when the window cover 1 is required to be in a closed state, the first driving source 16 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the driving gear 15 to rotate, so that the fixed tooth plate 12 is driven to move by the rotation of the driving gear 15, and the rectangular plate 7 is driven to move by the movement of the fixed tooth plate 12. When the rectangular plate 7 moves, the adjusting plate 20 will also move with it. When the adjusting plate 20 moves, it will drive the sliding block 6 to move. The sliding block 6 will change in height due to the shape of the adjusting groove 5. Because the adjusting plate 20 has the connecting rod 19, the entire adjusting plate 20 can cooperate with the sliding block 6 for angle adjustment, so that the blocking block 21 can slide into the window 22. In this way, the adjusting plate 20 and the blocking block 21 can be used to block the window 22, thereby achieving the purpose of preventing nuclear radiation leakage. By the reverse rotation of the first driving source 16, the blocking block 21 can be separated from the window 22, thereby realizing the opening operation of the window 22;

[0048] When it is necessary to observe the interior through the window 22, the block 21 is opened through the above-mentioned setting, and then the movement of the second driving source 32 can drive the movable tooth plate 31 to descend, and the descent of the movable tooth plate 31 can drive the driving end 29 to rotate, and then the rotation of the driving end 29 drives the driving rod 28 to rotate. When the driving rod 28 rotates, the driving gear 23 can be driven to rotate. At the same time, because the driving gear 23 is meshed with the teeth 34 in the arc groove 33, the driving gear 23 will rotate, and then drive the matching gear 36 to rotate, and the driven gear 25 is driven to rotate by the rotation of the matching gear 36, so that the rotating rod 24 can be rotated. Because the rotation direction of the meshing is opposite, the rotation direction of the rotating rod 24 is opposite to the rotation direction of the driving rod 28, so the rotating rod 24 and the driving rod 28 can move in an unfolded state, thereby realizing the shielding effect of pushing the protective glass 27 into the window 22, so that the staff can observe the interior through the window 22, and at the same time reduce the harm of nuclear radiation to the human body through the protective glass 27.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
