Description

Technical Field

[0001] The invention belongs to the technical field related to explosion-proof membrane windows, and specifically discloses a missile-proof explosion-proof membrane window for nuclear power. Background Art

[0002] Explosion-vent windows are special steel windows whose explosion-venting membranes automatically explode when the pressure difference between the inside and outside of a building reaches a certain value, reducing the internal pressure to protect the safety of people and property within the building. Explosion-venting membrane windows can prevent damage caused by overpressure caused by rupture of system-related pipes. Explosion-venting membrane windows are a passive system that does not require any special maintenance. They do not assist in room air flow and are only used in overpressure situations. The explosion-proof membrane window is composed of window frame, window sash, explosion-proof membrane, hinge, sealing assembly and other components.

[0003] Nuclear power plant containment structures must rapidly depressurize in the event of an accident (such as a hydrogen explosion or pipeline rupture). They must also consider external explosions, tornadoes, and projectiles. The existing explosion vents in the nuclear island and auxiliary buildings present several issues. The large number of imported products leads to high costs and long procurement cycles, creating significant challenges for post-operation repair and maintenance. Therefore, improvements are needed.

A connecting plate is provided on the outer wall of one side of the two pull rods, and sliding shells are installed on both sides of the connecting plate. The two groups of sliding shells are connected to the sliders through the provided guide members, and the two sliders are correspondingly connected to the anti-cylinder through the provided rotating members. The first guide rod is slidably installed inside the anti-cylinder, and the first guide rod is provided with a first spring on the outside of the first guide rod. A support rod is fixedly provided in the middle of the outer side of the connecting plate, and a cartridge is slidably sleeved on the outer side of the support rod, and a cartridge is provided on the outside of the cartridge. Both sides of the cartridge are connected to the first guide rod through a provided connecting assembly, and a locating pin is threadedly connected to the inner ends of the telescopic cylinder rod, and one end of the locating pin is against the outer surface of the pull rod.

[0005] Preferably, the self-locking assembly includes magnetic rods respectively arranged at the upper and lower ends of the outer side of the movable window, and positioning blocks are provided on the outer side of the installation frame and corresponding to the magnetic rods, and the positioning blocks are magnetically connected to the magnetic rods.

[0006] Preferably, the guide member includes a second guide rod, a baffle is fixedly provided on the outer side of the end of the sliding shell away from the support rod, the second guide rod slides and is inserted into the inside of the baffle, a second spring is mounted on the outside of the second guide rod, and the end of the second guide rod away from the baffle is connected to the outer side of the slider.

[0007] Preferably, the rotating member includes a rotating shaft rotatably mounted inside the slider, a rotating seat is sleeved on the outer side of the rotating shaft, and the rotating seat is fixedly connected to the cylinder.

[0008] Preferably, the connecting assembly includes a connecting buckle fixedly mounted on one side of the inner portion of the card shell, and the connecting buckle is rotatably connected to the first guide rod.

[0009] Preferably, screws are rotatably installed on the outside of the four cartridges, nuts are threadedly sleeved on the outside of the four screws, a flexible frame is commonly installed on the side of the four nuts away from the screws, and a protective elastic net is installed inside the flexible frame.

[0010] Preferably, the steel grille back support includes a grille outer frame, a steel grille is fixedly provided on the inner side of the grille outer frame, the steel grille is abutted against the explosion-proof diaphragm, and a plurality of fixing ears are symmetrically provided on the upper and lower sides of the grille outer frame, and the fixing ears are fastened to the movable window by fixing bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting suction cups and adjustment components at the four corners of the outer side of the movable window, the position of the suction cups can be adjusted according to the length of the explosion-proof diaphragm. After fixing the suction cups on the movable window, the protective elastic net is installed on the front end of the explosion-proof diaphragm through screws and nuts to prevent it from splashing and reduce the splashing of flying objects.

[0012] 2. By arranging a first guide rod, a first spring, a second guide rod, and a second spring below the protective elastic net, the protective elastic net can be buffered. When the protective elastic net is impacted, the impact force prompts the cartridge, the housing, the connecting buckle, and the first guide rod to squeeze the first spring and slide toward the inside of the cartridge. When the first spring reaches the peak value of the highest elastic contraction, it will prompt the slider to move toward the side of the baffle. At this time, the slider will press the second spring outside the second guide rod to consume the impact force in a horizontal manner, thereby enhancing the pressure-bearing performance of the protective elastic net and fully ensuring that there is buffer space when splashes impact the protective elastic net. The buffer space can fully offset the impact force, thereby intercepting the splashes and preventing them from flying out.

[0013] 3. By setting a steel grille back support on the inner side of the explosion venting diaphragm, it can serve as a back support for the explosion venting diaphragm to resist external explosions. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1-9The illustrated embodiment of a nuclear power projectile explosion-proof membrane window comprises a mounting frame 1 and a movable window 2, which are rotatably connected. A self-locking assembly is provided on the outside of the movable window 2, and a steel grid backing 27 and an explosion-proof membrane 9 are embedded inside the movable window 2. Adjustment assemblies are provided on both sides of the outer surface of the explosion-proof membrane 9, and suction cups 5 are provided at both ends of the adjustment assembly. The suction cups 5 are adsorbed on the outer surface of the movable window. The installation frame 1 is the outer window frame of the explosion-proof window, and the movable window 2 is the inner frame of the explosion-proof window. During installation, the adjustment component and the suction cup 5 are both installed on the outer surface of the explosion-proof diaphragm 9 close to the room; The material used to make the explosion venting diaphragm 9 has stable mechanical properties and thermal stability, and can withstand an external explosion load of 20kPa when supported by a steel grid. The explosion relief diaphragm implosion opening pressure difference is 5KP, 10kPa (implosion pressure difference), and the response time is ≤0.5s; After the explosion-venting diaphragm 9 bursts, it can be replaced. In the event of a burst, no membrane fragments will damage any other equipment in the surrounding area. The explosion-venting diaphragm 9 is manufactured with different cracks. Importantly, when the explosion-venting diaphragm 9 breaks, it occupies the smallest possible space. Therefore, when the explosion-venting diaphragm 9 bursts, it will not affect or splash other equipment. The explosion-venting diaphragm 9 will be cracked around the diaphragm. The self-locking component includes magnetic rods 8 respectively arranged at the upper and lower ends of the outer side of the movable window 2, and positioning blocks 7 are provided on the outer side of the installation frame 1 and corresponding to the magnetic rods 8. The positioning blocks 7 are magnetically connected to the magnetic rods 8. The pressure difference for the self-locking component to implode and open is greater than the pressure difference for the explosion-proof diaphragm 9 to open and implode.

[0019] The adjustment assembly includes a telescopic rod 3, and pull rods 12 are slidably installed at both ends of the telescopic rod 3, and the two pull rods 12 are fixedly connected to the outer sides of the corresponding suction cups 5; The pull rod 12 can slide inside the telescopic rod 3 to adjust the installation position of the suction cup 5 according to the length of the explosion-proof diaphragm 9; When the indoor air pressure continues to increase, and the explosion relief diaphragm 9 exceeds the explosion relief pressure but has not yet formed an explosion relief, the air pressure will push the movable window 2. At this time, the magnetic rod 8 will be separated from the positioning block 7, and the movable window 2 will open outward around the rotation connection point, releasing the internal pressure and avoiding structural damage, thereby ensuring the stability of the explosion relief. The positioning block 7 can be made of metal material, so that the movable window 2 can be automatically magnetically attracted when closed.

[0020] The outer wall of one side of the two pull rods 12 is provided with a connecting plate 29, and sliding shells 23 are installed on both sides of the connecting plate 29. Under the connection of the connecting plate 29, the sliding shell 23 can be stably installed on one side of the pull rod 12. The two sets of sliding shells 23 are connected with sliders 31 through the provided guide members. The two sliders 31 are correspondingly connected with the cylinder 22 through the provided rotating members. The first guide rod 17 is slidably installed inside the cylinder 22, and the first guide rod 17 is provided with a first spring 21 on the outside. A support rod 33 is fixedly provided in the middle of the outer side of the connecting plate 29. The outer side of the support rod 33 is slidably sheathed with a cartridge 10, and a cartridge 19 is provided on the outside of the cartridge 10. Both sides of the interior of the cartridge 19 are connected to the first guide rod 17 through a provided connecting assembly. The two ends of the interior of the telescopic cylinder rod 3 are threadedly connected with locating pins 16, and one end of the locating pin 16 is against the outer surface of the pull rod 12; When the impact force of the splashing object presses against the protective elastic net 4, the housing 19 and the cartridge 10 are pressed downward, pressing against the first spring 21 outside the first guide rod 17 at the lower end. The first spring 21 is elastically deformed and pushes the slider 31 to move. The positioning pin 16 facilitates limiting the position of the pulled-out pull rod 12 .

[0021] The guide member includes a second guide rod 18. A baffle 15 is fixedly provided on the outer side of the end of the sliding housing 23 away from the support rod 33. The second guide rod 18 slides through the interior of the baffle 15. A second spring 30 is sleeved on the exterior of the second guide rod 18. The end of the second guide rod 18 away from the baffle 15 is connected to the outer side of the slider 31. When the stopper 22 and the slider 31 move toward one side of the sliding housing 23 , the corresponding sliding housing 23 will squeeze the second spring 30 outside the second guide rod 18 , thereby further offsetting the impact force of the splashing objects.

[0022] The rotating member includes a rotating shaft 28 rotatably mounted inside the slider 31, and a rotating seat 32 is mounted on the outer side of the rotating shaft 28. The rotating seat 32 is fixedly connected to the cylinder 22; By rotating the rotating seat 32 and clamping it on the outer side of the rotating shaft 28, the cylinder 22 can be rotated at a certain angle when moving.

[0023] The connecting assembly includes a connecting buckle 20 fixedly mounted on one side of the inner portion of the card housing 19, and the connecting buckle 20 is rotatably connected to the first guide rod 17; Under the connection of the connecting buckle 20 , when the first guide rod 17 is squeezed and slid by impact, the first guide rod 17 can cooperate with the first spring 21 to buffer deformation.

[0024] The four cartridges 10 are all rotatably mounted with screws 24 on their outer sides, and the four screws 24 are all threadedly fitted with nuts 25 on their outer sides. A flexible frame 6 is commonly mounted on the side of the four nuts 25 away from the screws 24, and a protective elastic net 4 is installed inside the flexible frame 6. The flexible frame 6 can be made of silicone material, so when the nut 25 is driven to rotate, it can be stretched accordingly, so that the nut 25 at the corner is connected to the screw 24, and then the protective elastic net 4 is installed to one side of the explosion-proof diaphragm 9 to prevent splashing. This design makes the installation and disassembly of the protective elastic net 4 more convenient.

[0025] The steel grille back support 27 includes a grille outer frame 13, a steel grille 11 is fixedly arranged on the inner side of the grille outer frame 13, the steel grille 11 is against the explosion-proof diaphragm 9, and a plurality of fixing ears 14 are symmetrically arranged on the upper and lower sides of the grille outer frame 13. The fixing ears 14 are fastened to the movable window 2 by fixing bolts 26; by setting the fixing ears 14, fixing bolts 26 and the grille outer frame 13, the steel grille 11 can be fixedly attached to the outer surface of the explosion-proof diaphragm 9, so that the steel grille 11 serves as a back support for the explosion-proof diaphragm 9 when resisting external explosions.

[0026] Working principle: According to the length of the explosion-proof diaphragm 9, the pull rod 12 inside the telescopic rod 3 is stretched accordingly, causing the suction cup 5 to be adsorbed on the outer surface of the movable window 2, and then the positioning pin 16 is screwed in from the inside of the telescopic rod 3, so that one end of the positioning pin 16 is pressed against the outer surface of the pull rod 12 to fix the position of the pull rod 12. At this time, the staff correspondingly screws the nut 25 on the outer surface of the flexible frame 6 to the screw 24 on the outside of the corresponding cartridge 10, thereby stretching the flexible frame 6 and erecting it on the front end of the explosion-proof diaphragm 9. As a result, the protective elastic net 4 inside the flexible frame 6 can protect the front end of the explosion-proof diaphragm 9 and reduce the splashing of indoor flying objects. When the splashing objects splash toward the explosion-proof diaphragm 9, the protective elastic net 4 will be impacted at the front end of the explosion-proof diaphragm 9. The impact force will prompt the cartridge 10, the card shell 19, the connecting buckle 20, and the first guide rod 17 to squeeze the first spring 21. At this time, the first guide rod 17 slides toward the inside of the cylinder 22. When the first spring 21 reaches the peak value of the highest elastic contraction, it will prompt the slider 31 to move toward the side of the baffle 15. The slider 31 will press the second spring 30 outside the second guide rod 18, thereby offsetting the impact force through lateral movement, thereby enhancing the pressure-bearing performance of the protective elastic net 4, and fully ensuring that there is a reserved buffer space when the splashing objects impact the protective elastic net 4. The buffer space can fully offset the impact force, thereby preventing the splashing objects from flying out.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
