Description

Technical Field

[0001] This invention relates to the field of roller shutter door safety technology, and in particular to a safety device for roller shutter doors in ship and aircraft hangars and its usage method. Background Technology

[0002] A roller shutter door is a door with multiple articulated door panels linked together, which rotate up and down around a central axis at the top of the door within fixed tracks. Roller shutter doors are commonly used in shops.

[0003] Roller shutters, like walls, serve as horizontal partitions. They consist of multiple parts, including curtain panels, base plates, guide rails, supports, rollers, housings, control boxes, roller motors, limit switches, lintels, manual quick-release switches, push-button switches, and safety devices. They are generally installed in locations where it is inconvenient to use walls for partitioning.

[0004] Since most roller shutters use self-locking devices to secure them, these devices are prone to malfunction and falling due to prolonged wear and tear, potentially endangering nearby personnel and property. Furthermore, because the roller shutter is located on the surface of a ship, storms and waves can easily cause the deck to become damp and flooded. When aircraft are parked or under maintenance, parts are often replaced, and not all parts are waterproof; therefore, it is necessary to ensure that the parts are not corroded by seawater. To ensure the safety of aircraft and nearby personnel, this application provides a safety device and method for using a ship's aircraft hangar roller shutter to meet these requirements. Summary of the Invention

[0007] Preferably, the connecting box and the positioning post are welded together at the factory, and a fixing hole is provided on the inner side of the connecting box, into which a fixing post is inserted.

[0008] Preferably, a gear groove is provided on the inner side of the door frame, and the gear groove meshes with the moving gear.

[0009] Preferably, a waterproof motor is snapped into the inside of the support plate, a control shaft is inserted into the inside of the waterproof motor, and a belt is sleeved on the outer surface of the control shaft.

[0010] Preferably, a waterproof shaft is sleeved on the inner side of the belt, and a flood control plate is sleeved on the outer surface of the waterproof shaft. A connecting groove is formed on the upper surface of the flood control plate.

[0011] Preferably, a spare battery is inserted into one side of the door frame, a driver is snapped into the inside of the door frame, and a warning light is provided on one side of the door frame. A retaining ring is provided on one side of the door frame, a roller shutter door groove is opened on the inner side of the door frame, and a door railing is provided on the other side of the door frame.

[0012] Preferably, the upper surface of the support plate is provided with a bolt groove, an expansion bolt is inserted into the inside of the bolt groove, and a waterproof clamp is snapped onto the upper surface of the bolt groove.

[0013] Preferably, a side bolt is inserted into the other side of the door frame, and a connecting plate is inserted into the upper surface of the door frame.

[0014] Preferably, a drainage pipe is snapped into the inside of the support plate, a drainage pump is inserted into the inside of the drainage pipe, a drainage motor is snapped into one side of the drainage pump, and a drainage wheel is inserted into the inside of the drainage motor.

[0015] A method for using a safety device for a ship's aircraft hangar roller shutter door includes the following steps: Step 1: First, raise the roller shutter door, then start the moving motor to rotate the moving gear so that the moving device and the connecting box move to the position of the roller shutter door slot. Insert the positioning pin into the positioning hole. When the equipment is running, the warning light will emit a warning light. Step 2: When the roller shutter door falls, the anti-collision pad protects the buffer plate, which reduces the impact force from the roller shutter door through the buffer spring and buffer sponge. Step 3: In the event of a power outage, the power can be supplied by the backup battery. In the event of a equipment malfunction, the extension column needs to be manually pushed to detach the fixing column from the connection box. The connection box can then be moved by hand using the touch groove. Step 4: When repairing or overhauling the moving device and connecting box, rotate the locking shaft by hand to loosen the locking shaft and the retaining ring, so that the cover can be opened by hand; Step 5: When waves crash against the deck, the waterproof motor rotates the control shaft, causing the belt to drive the waterproof shaft and the floodproof plate to rotate together, keeping the floodproof plate upright to prevent seawater from flowing back in; Step 6: When the roller shutter door needs to be lowered, the positioning pin needs to be manually pushed to disengage it from the positioning hole before the connecting box can be moved by the moving device or manually. Step 7: When there is too much seawater on the deck surface, the drain motor rotates the drain wheel to suck away the surrounding seawater. When the seawater passes through the surface of the drain pipe, larger debris will be filtered out by the filter screen. The seawater will then enter the drain pump through the drain pipe and then be discharged from the hull through the subsequent pipe.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, after the roller shutter door rises, the moving motor rotates the moving gear to move the connecting box and the moving device. The positioning pin is inserted into the positioning hole. The anti-collision pad reduces the impact through the buffer sponge and buffer spring. The extension column is moved manually, and the connecting box is disengaged from the moving device. The connecting box is pushed by hand through the touch groove, and the positioning pin is manually pushed out of the positioning hole. The locking shaft is rotated to release the retaining ring. The opening and closing groove assists in opening the cover plate. The double-control slide moves the connecting box. The backup battery provides power. The warning light provides optical warning. The waterproof motor rotates the control shaft to make the belt drive the flood control plate to rotate. The expansion bolts fix the support plate. The waterproof plate prevents water from entering the bolt groove. The side bolts fix the door frame. The connecting plate is connected to the roller shutter door. The drainage motor rotates the drainage wheel to filter the seawater through the filter screen on the surface of the drainage pipe. The seawater enters the drainage pump through the drainage pipe and finally flows into other pipes and is discharged from the hull.

[0017] By incorporating flood barriers, connecting boxes, and mobile devices, the equipment's effectiveness is greatly enhanced. This effectively ensures the safety of nearby personnel and property, prevents sudden collapse of the roller shutter door that could cause injury or damage, and significantly alleviates the problem of water ingress into ship and aircraft hangars.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides a safety device and method for using a roller shutter door of a ship's aircraft hangar, including a door frame 1. A moving device 2 is inserted into the inner side of the door frame 1. A moving motor 3 is inserted into the upper surface of the moving device 2. A moving gear 4 is inserted into the interior of the moving motor 3. A slide groove 5 is provided on one side of the moving device 2. A handle 6 is provided at one end of the moving device 2. A connecting box 7 is sleeved on the outer surface of the slide groove 5. A positioning pin 8 is inserted into the interior of the connecting box 7. A cushioning sponge 9 is provided on the upper surface of the connecting box 7. A positioning post 10 is provided on the upper surface of the connecting box 7. A cushioning spring 11 is sleeved on the outer surface of the positioning post 10. A cushioning plate 12 is sleeved on the outer surface of the cushioning spring 11. An anti-collision pad 13 is provided on the upper surface of the cushioning plate 12. A touch groove 14 is provided on one side of the connecting box 7. A fixing groove 15 is provided on one side of the moving device 2. An extension post 16 is inserted into the fixing groove 15. A fixing post 17 is provided on one side of the extension post 16. The connecting box 7 and the positioning post 10 are welded at the factory. A fixing groove 17 is provided on the inner side of the connecting box 7. The fixed hole has a fixed post 17 inserted inside. The inner side of the door frame 1 has a gear groove that meshes with the moving gear 4. During use, when the roller shutter door is raised, the moving motor 3 can rotate the moving gear 4 to move the moving device 2. The connecting box 7 will move together with the fixed post 17 and the moving device 2, causing the anti-collision pad 13 to move into the inside of the roller shutter door groove 38. At this time, the positioning pin 8 will be inserted into the positioning hole 19 to prevent the connecting box 7 from moving due to the hull's swaying. When the roller shutter door falls due to wear and tear of the self-locking device, it will be caught by the anti-collision pad 13. At this time, the anti-collision pad 13 will reduce the impact force due to the action of the buffer sponge 9 and the buffer spring 11, thereby better protecting the roller shutter door and preventing the roller shutter door from falling and hitting objects. When the equipment is damaged or there is a power outage, the extension post 16 and the fixed post 17 can be moved manually to disengage the connecting box 7 from the moving device 2. Then, the connecting box 7 can be moved by hand at the position of the touch groove 14.

[0027] When the roller shutter needs to be lowered, the operator needs to manually push the positioning pin 8 to disengage it from the positioning hole 19 before the connecting box 7 can be moved. This reduces the possibility of the roller shutter falling and damaging objects due to operational errors. For long-term use, only one connecting box 7 needs to be installed. The other slide 5 is used for maintenance or replacement of the connecting box 7.

[0028] like Figure 4 and Figure 5 As shown, in this embodiment, the inner side of the door frame 1 is provided with a double-control sliding groove 18, the upper surface of the inner side of the door frame 1 is provided with a positioning hole 19, a fixing bolt 20 is threaded through one side of the door frame 1, a hinge 21 is threaded through the fixing bolt 20, a cross bolt 22 is threaded through one side of the hinge 21, a cover plate 23 is threaded through the hinge 21 and the cross bolt 22, a rotating hole 24 is provided on one side of the cover plate 23, a locking shaft 25 is inserted into the rotating hole 24, and an opening and closing recess is provided on one side of the cover plate 23. The door frame 1 has a spare battery 34 inserted into one side of the slot 26. The door frame 1 has a drive 35 inserted inside. The door frame 1 has a warning light 36 on one side and a retaining ring 37 on one side. The door frame 1 has a roller shutter door slot 38 on the inside. During use, when it is necessary to inspect the connecting box 7 and the moving device 2, the locking shaft 25 and the retaining ring 37 can be released by rotating the locking shaft 25, so that the cover plate 23 can be flipped by the hinge 21. The opening and closing groove 26 can assist the staff to manually open the cover plate 23.

[0029] The connecting box 7 can be moved via the dual-control slide 18, the backup battery 34 provides power to the inside of the mobile device 2 in the event of a power shortage, and the warning light 36 provides optical warning when the device is running.

[0030] like Figure 6 and Figure 7 As shown, in this embodiment, the lower surface of the door frame 1 is provided with a support plate 27. A waterproof motor 28 is snapped into the inside of the support plate 27. A control shaft 29 is inserted into the inside of the waterproof motor 28. A belt 30 is sleeved on the outer surface of the control shaft 29. A waterproof shaft 31 is sleeved on the inner side of the belt 30. A floodproof plate 32 is sleeved on the outer surface of the waterproof shaft 31. A connecting groove 33 is opened on the upper surface of the floodproof plate 32. A door railing 39 is provided on the other side of the door frame 1. A bolt groove 40 is opened on the upper surface of the support plate 27. An expansion bolt 41 is inserted into the inside of the bolt groove 40. A waterproof clamping plate 42 is snapped into the upper surface of the bolt groove 40. A side bolt 43 is inserted into the other side of the door frame 1. A connecting plate 44 is inserted into the upper surface of the door frame 1. During use, when the deck is wetted by sea waves, the control shaft 29 can be rotated by the waterproof motor 28 to make the belt 30 drive the waterproof shaft 31 and the floodproof plate 32 to rotate together. The floodproof plate 32 rotates 90 degrees to prevent seawater backflow.

[0031] The support plate 27 is fixed by expansion bolts 41, the waterproof plate 42 is to prevent water from entering the bolt groove 40 and causing the expansion bolts 41 to rust, the side bolts 43 are used to fix the door frame 1, and the connecting plate 44 can be connected to the roller shutter door.

[0032] like Figure 8 As shown, in this embodiment, a drainage pipe 45 is snapped into the inside of the support plate 27, a drainage pump 46 is inserted into the inside of the drainage pipe 45, a drainage motor 47 is snapped into one side of the drainage pump 46, and a drainage wheel 48 is inserted into the inside of the drainage motor 47. During use, when there is too much seawater around, the drainage motor 47 can be started to rotate the drainage wheel 48, so that the seawater near the door frame 1 is filtered by the filter screen on the surface of the drainage pipe 45. The seawater will enter the interior of the drainage pump 46 along the drainage pipe 45, and finally flow into other pipes and be discharged from the hull, thereby quickly discharging the seawater and reducing the time that the hull surface is corroded by seawater.

[0033] All electrical components mentioned in this article are connected to an external ULN2003 main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0034] A safety device for a ship's aircraft hangar roller shutter door and its usage method include the following steps; Step 1: First, the roller shutter door needs to be raised. Then, start the moving motor 3 to rotate the moving gear 4 so that the moving device 2 and the connecting box 7 can be moved to the position of the roller shutter door groove 38. The positioning pin 8 is inserted into the positioning hole 19. When the equipment is running, the warning light 36 will emit a warning light. Step 2: When the roller shutter door falls, the anti-collision pad 13 protects the buffer plate 12. The buffer plate 12 reduces the impact force from the roller shutter door through the buffer spring 11 and the buffer sponge 9. Step 3: In the event of a power outage, the power can be supplied by the backup battery 34. In the event of a device malfunction, the extension column 16 needs to be manually pushed to disengage the fixing column 17 from the connection box 7. The connection box 7 can then be moved by hand using the touch groove 14. Step 4: When repairing or overhauling the moving device 2 and the connecting box 7, rotate the locking shaft 25 by hand to loosen the locking shaft 25 and the retaining ring 37, so that the cover plate 23 can be opened by hand. Step 5: When waves crash against the deck, the waterproof motor 28 rotates the control shaft 29, causing the belt 30 to drive the waterproof shaft 31 and the floodproof plate 32 to rotate together. The floodproof plate 32 stands upright to prevent seawater from flowing back in. Step 6: When the roller shutter door needs to be lowered, the positioning pin 8 needs to be manually pushed to disengage it from the positioning hole 19 before the connecting box 7 can be moved by the moving device 2 or manually. Step 7: When there is too much seawater on the deck surface, the drain motor rotates the drain wheel to suck away the surrounding seawater. When the seawater passes through the surface of the drain pipe, larger debris will be filtered out by the filter screen. The seawater will then enter the drain pump through the drain pipe and then be discharged from the hull through the subsequent pipe.

[0035] The technical solution provided by this invention is as follows: During use, when the roller shutter door is raised, the moving motor 3 can rotate the moving gear 4 to move the moving device 2. The connecting box 7 will move together with the moving device 2 due to the fixed column 17, causing the anti-collision pad 13 to move into the inside of the roller shutter door groove 38. At this time, the positioning pin 8 will be inserted into the positioning hole 19 to prevent the connecting box 7 from moving due to the hull's swaying. When the roller shutter door falls due to wear and tear of the self-locking device, it will be caught by the anti-collision pad 13. At this time, the anti-collision pad 13 will reduce the impact force due to the action of the buffer sponge 9 and the buffer spring 11, thereby better protecting the roller shutter door and preventing it from falling and hitting the roller shutter door. When the equipment malfunctions or a power outage occurs, the extension column 16 and the fixed column 17 can be manually moved to disengage the connecting box 7 from the moving device 2. Then, the connecting box 7 can be moved by hand at the touch groove 14. When the roller shutter needs to be lowered, the operator needs to manually push the positioning pin 8 to disengage it from the positioning hole 19 before the connecting box 7 can be moved. This reduces the possibility of the roller shutter falling and damaging objects due to operational errors. For long-term use, only one connecting box 7 needs to be installed. The other slide groove 5 is used for maintenance or replacement of the connecting box 7. When it is necessary to inspect the connecting box 7 and the moving device 2, the locking shaft 25 can be rotated to engage the locking shaft 25 with the locking device 2. Ring 37 is loosened, allowing cover 23 to be flipped via hinge 21. Opening groove 26 assists staff in manually opening cover 23. Connecting box 7 can be moved via double-control slide 18. Backup battery 34 provides power to the internal components of mobile device 2 in case of power failure. Warning light 36 provides optical warning during equipment operation. When the deck is wetted by waves, waterproof motor 28 rotates control shaft 29, causing belt 30 to drive waterproof shaft 31 and floodproof plate 32 to rotate together. Floodproof plate 32 rotates 90 degrees to prevent seawater backflow. Expansion bolts 41 secure support plate 27. Waterproof clamp 42 prevents water from entering bolt groove 40, causing expansion bolts 41 to rust. The side bolts 43 are used to fix the door frame 1. The connecting plate 44 can be connected to the roller shutter door. When there is too much seawater around, the drainage motor 47 can be started to rotate the drainage wheel 48, so that the seawater near the door frame 1 is filtered by the filter screen on the surface of the drainage pipe 45. The seawater will enter the interior of the drainage pump 46 through the drainage pipe 45 and finally flow into other pipes and be discharged from the hull, thereby quickly draining the seawater, reducing the time that the hull surface is corroded by seawater, greatly improving the use effect of the equipment, effectively ensuring the safety of nearby personnel and objects, preventing the roller shutter door from suddenly falling and causing injury to personnel or damage to objects, and greatly alleviating the problem of easy water ingress into the ship's aircraft hangar.
