Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to an emergency water-spraying fireproof rolling shutter door. Background Technology

[0002] Fire-resistant roller shutters are fire-resistant and heat-insulating facilities suitable for large openings in buildings. In addition to the functions of ordinary doors, they have special functions such as fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation.

[0003] With the development of existing technology, some fireproof rolling shutters are equipped with automatic sprinkler heads that can spray cold water in emergencies to achieve the purpose of emergency cooling. However, the existing sprinkler heads are mostly fixed in position during installation, which results in a limited range of cold water spraying and an inability to comprehensively cool the area around the fireproof door, thus reducing the practicality of the sprinkler heads.

[0004] To address this, a publicly available technology proposes an emergency-spraying fireproof rolling shutter door, including a fireproof door frame. A mounting box is fixedly connected to the top of the fireproof door frame, running through it front and back. The inner wall of the mounting box is connected to a drive mechanism for driving a moving rack to move back and forth. This technology utilizes the interplay between the fireproof door frame, mounting box, mounting tube, moving rack, drive mechanism, gears, and spray mechanism. The drive mechanism moves the moving rack, which in turn drives the mounting tube to rotate via gears. The reciprocating rotation of the mounting tube causes the spray mechanism to swing back and forth, effectively expanding the spray range of the spray mechanism.

[0005] However, the drive structure in the above-disclosed technology that drives the oscillating spray mechanism has the following drawbacks: the structure is redundant and complex, requiring the linkage of multiple transmission components such as motors, gears, and racks, which increases the risk of failure; the actual effect is limited, the oscillation amplitude of the spray pipe is limited by the mechanical structure, and it cannot cover the full width area of ​​the roller shutter door, resulting in low high-temperature adaptability.

[0006] Therefore, it is necessary to improve and optimize the structure of the emergency water-spraying fireproof rolling shutter door to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an emergency water-spraying fireproof rolling shutter door.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an emergency water-spraying fireproof rolling shutter door, comprising a fire water pipe, a door frame, a rolling shutter panel, and two sets of housings. The two sets of housings are respectively fixedly connected to the front and rear sides of the door frame and are both close to the top of the door frame. The side of the housing away from the door frame is open. A side cover for covering the front opening of the housing is rotatably connected to the side of the housing away from the door frame. A rectangular opening is provided at the bottom of the housing. A bottom cover for covering the rectangular opening is rotatably connected to the bottom of the housing. A first water distribution pipe is fixedly connected to the side of the side cover facing the housing. A first water spray pipe is fixedly connected to the end of the first water distribution pipe facing the inside of the housing through multiple sets of first connecting pipes. A second water distribution pipe is fixedly connected to the inner wall of the rectangular opening through a bracket. A second water spray pipe is fixedly connected to the lower wall of the second water distribution pipe through multiple sets of second connecting pipes. A snap-fit ​​structure for snap-fit ​​fixing is provided between the side cover and the bottom cover. An elastic structure for assisting the bottom cover to pop out is provided on the lower wall of the housing. An electric telescopic rod for driving the side cover to rotate and open is provided inside the housing.

[0009] As a further description of the above technical solution:

[0010] The first water distribution pipe and the second water distribution pipe are fixedly connected to water inlet pipes at both ends. The multiple sets of water inlet pipes are connected to the fire water pipe through a set of flexible hoses. An electric control valve is installed between the flexible hose and the fire water pipe.

[0011] As a further description of the above technical solution:

[0012] The electric telescopic rod is rotatably connected between the inner side wall of the box and the side cover facing the inside of the box via two sets of rotating seats.

[0013] As a further description of the above technical solution:

[0014] The elastic structure is a spring. A mounting hole is provided at the bottom of the box and in front of the rectangular opening. The spring is fixed to the inner wall of the mounting hole by screws, and the lower end of the spring abuts against the upper wall of the bottom cover.

[0015] As a further description of the above technical solution:

[0016] The snap-fit ​​structure includes a snap pin and a slot. The snap pin is located at the end of the bottom cover facing the side cover, and the slot is located on the side of the side cover facing the housing and corresponds to the position of the snap pin. The lower wall of the snap pin is provided with a protruding ridge, and the lower inner wall of the slot is provided with a groove that matches the protruding ridge.

[0017] As a further description of the above technical solution:

[0018] The second water spray pipe has a ring-shaped structure when viewed from the front, and the first water spray pipe has a ring-shaped structure when viewed from above.

[0019] As a further description of the above technical solution:

[0020] Multiple sets of spray holes are provided on the side of the second water spray pipe away from the second water distribution pipe and on the side of the first water spray pipe away from the first water distribution pipe.

[0021] This utility model has the following beneficial effects:

[0022] 1. Compared with existing technologies, this emergency water-spraying fireproof rolling shutter door features a concealed structure that enhances both aesthetics and safety. When not in use, the casing completely covers the water spray pipes and sprinkler components, preventing pipe exposure and simplifying the appearance of the equipment. It also reduces the risk of external environmental corrosion to core components. When in use, the side and bottom covers are automatically unfolded by an electric telescopic rod, ensuring that the sprinkler system quickly enters working condition without relying on complex mechanical transmission structures.

[0023] 2. Compared with existing technologies, this emergency water-spraying fireproof rolling shutter door provides full-coverage spraying, eliminating blind spots. It employs a ring-shaped spray pipe combined with multiple spray holes to form two continuous water walls on the outside of the shutter door, replacing traditional swing-type sprinklers and achieving large-area spray coverage. This eliminates the waterless blind spots between adjacent sprinklers found in traditional technologies. Reliability is significantly enhanced in high-temperature environments. The elimination of precision transmission mechanisms such as gears and racks, along with a combination of elastic release and gravity-based descent, avoids metal deformation or electronic component failure caused by high temperatures. The fixed layout of the spray pipes eliminates the need for dynamic adjustments, reducing the failure rate and ensuring stable operation of the emergency water-spraying function under extreme conditions.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 6 This utility model provides an emergency water-spraying fireproof rolling shutter door, which includes a fire water pipe, a door frame 1, a rolling shutter panel 3, and two sets of boxes 2. The boxes 2 serve as the installation carrier for the sprinkler system. Under normal circumstances, their openings are closed by side covers 4 and bottom covers 5 to prevent the sprinkler pipes from being exposed and to improve the overall aesthetics of the equipment. In case of fire, the sprinkler components inside the boxes 2 can be quickly deployed to ensure the efficiency of emergency function activation.

[0034] To completely shield the sprinkler assembly when not in use, and to ensure rapid deployment in an emergency, two sets of housings 2 are fixedly connected to the front and rear sides of the gantry 1 and are close to the top of the gantry 1. The side of housing 2 away from the gantry 1 is open. A side cover 4 for covering the front opening of housing 2 is rotatably connected to the side of housing 2 away from the gantry 1. A rectangular opening is provided at the bottom of housing 2. A bottom cover 5 for covering the rectangular opening is rotatably connected to the bottom of housing 2.

[0035] The side cover 4 and the bottom cover 5 are normally closed to form a sealed protective layer to prevent dust and high temperature from directly corroding the spray pipe; in an emergency, the side cover 4 is driven to rotate outward and unfold by the electric telescopic rod 18, and the bottom cover 5 automatically falls under the action of the spring force 8 and its own weight, so as to realize the rapid exposure of the spray components and start the water spraying operation.

[0036] To achieve full coverage of the spray range and eliminate the blind spots of traditional swing sprinklers, a first water distribution pipe 9 is fixedly connected to the side of the side cover 4 facing the box 2. The end of the first water distribution pipe 9 facing the inside of the box 2 is fixedly connected to a first water spray pipe 11 through multiple sets of first connecting pipes 10. A second water distribution pipe 14 is fixedly connected to the inner wall of the rectangular opening through a bracket. A second water spray pipe 16 is fixedly connected to the lower wall of the second water distribution pipe 14 through multiple sets of second connecting pipes 15. Water inlet pipes 13 are fixedly connected to both ends of the first water distribution pipe 9 and both ends of the second water distribution pipe 14. Multiple sets of water inlet pipes 13 are connected to fire water pipes through a set of flexible hoses. An electric control valve is installed between the flexible hoses and the fire water pipes. The front view projection of the second water spray pipe 16 is a ring structure, and the top view projection of the first water spray pipe 11 is a ring structure. Multiple sets of spray holes 12 are provided on the side of the second water spray pipe 16 away from the second water distribution pipe 14 and the side of the first water spray pipe 11 away from the first water distribution pipe 9.

[0037] After the water spray is started, the water flows through the fire water pipe and the water inlet pipe 13 to the first water spray pipe 11 and the second water spray pipe 16. Through the ring layout and multi-directional water spray holes 12, the water is sprayed outward to form two three-dimensional water walls on the outside of the roller shutter door. The horizontal water wall covers the entire width of the roller shutter door and the vertical water wall covers the height range of the door body, completely eliminating the drawback of the lack of water blind spots between adjacent sprinklers in traditional technology.

[0038] To prevent the side cover 4 and bottom cover 5 from being accidentally opened due to external force or vibration when not in use, a snap-fit ​​structure for snap-fit ​​fixing is provided between the side cover 4 and bottom cover 5. The snap-fit ​​structure includes a snap pin 7 and a slot 6. The snap pin 7 is located at the end of the bottom cover 5 facing the side cover 4, and the slot 6 is located on the side of the side cover 4 facing the box body 2 and corresponds to the position of the snap pin 7. The lower wall of the snap pin 7 is provided with a protrusion 701, and the lower inner wall of the slot 6 is provided with a groove that matches the protrusion 701.

[0039] Under normal conditions, the locking pin 7 is inserted into the locking slot 6 and the relative positions of the side cover 4 and the bottom cover 5 are locked by the engagement of the protrusion 701 and the groove; in an emergency, the electric telescopic rod 18 pushes the side cover 4 to rotate, the locking slot 6 disengages from the locking pin 7, and the bottom cover 5 pops open simultaneously, ensuring the reliability of the linkage release between the side cover 4 and the bottom cover 5.

[0040] To ensure that the bottom cover 5 can be quickly opened in an emergency without relying on electric drive, the lower wall of the box body 2 is provided with an elastic structure to assist the bottom cover 5 in popping out. The elastic structure is a spring 8. The bottom of the box body 2 and the front side of the rectangular opening are provided with a mounting hole. The spring 8 is fixedly connected to the inner wall of the mounting hole by screws. The lower end of the spring 8 abuts against the upper wall of the bottom cover 5.

[0041] Under normal conditions, spring 8 is in a compressed state, providing support force when the bottom cover 5 is closed; in an emergency, after the locking structure is released, spring 8 releases its elastic force and, together with the weight of the bottom cover 5, makes it fall quickly, avoiding the traditional mechanical transmission mechanism from jamming or failing due to high temperature.

[0042] To enable the automatic unfolding of the side cover 4 and simplify the drive structure in high-temperature environments, an electric telescopic rod 18 is provided inside the housing 2 to drive the side cover 4 to rotate and open. The electric telescopic rod 18 is rotatably connected between the inner wall of the housing 2 and the side of the side cover 4 facing the inside of the housing 2 through two sets of rotating seats 17.

[0043] After the fire signal is triggered, the electrically controlled valve opens the fire water pipe to supply water, and the electric telescopic rod 18 extends synchronously, pushing the side cover 4 to rotate outward to a horizontally unfolded state. After unfolding, the side cover 4 serves as a support platform for the first sprinkler pipe 11. When the side cover 4 is opened, the bottom cover 5 is released simultaneously. This setting can avoid the failure risk of traditional gear transmission structures at high temperatures, and at the same time reduce mechanical linkage links to reduce the failure rate.

[0044] Working principle: Under normal conditions, the side cover 4 and bottom cover 5 are closed to form a sealed protective layer, preventing dust and high temperature from directly corroding the sprinkler pipes. In an emergency, the side cover 4 is driven to rotate outward and unfold by the electric telescopic rod 18, and the bottom cover 5 automatically falls under the force of the spring 8 and its own weight, realizing the rapid exposure of the sprinkler components and the start of the water spraying operation. After the water spraying is started, the water flows through the fire water pipe and the inlet pipe 13 to the first water spray pipe 11 and the second water spray pipe 16, and is sprayed outward through the ring layout and multi-directional water spray holes 12, forming two three-dimensional water walls on the outside of the roller shutter door, covering the entire width of the roller shutter door horizontally and the height range of the door vertically, completely eliminating the drawback of the lack of water blind spots between adjacent sprinklers in traditional technology. Under normal conditions, the locking pin 7 is inserted into the locking slot 6, and the relative positions of the side cover 4 and the bottom cover 5 are locked by the engagement of the protrusion 701 and the groove. In an emergency, the electric telescopic rod 18 pushes the side cover 4 to rotate, the locking slot 6 disengages from the locking pin 7, and the bottom cover 5 pops open simultaneously, ensuring the reliability of the linkage release between the side cover 4 and the bottom cover 5. Under normal conditions, the spring 8 is in a compressed state, providing support force when the bottom cover 5 is closed. In an emergency, after the locking structure is released, the spring 8 releases its elastic force and, together with the weight of the bottom cover 5, makes it fall quickly, avoiding the jamming or failure of the traditional mechanical transmission mechanism due to high temperature. After the fire signal is triggered, the electric control valve opens the fire water pipe to supply water, and the electric telescopic rod 18 extends simultaneously and pushes the side cover 4 to rotate outward to the horizontal unfolded state. After the side cover 4 is unfolded, it serves as a support platform for the first sprinkler pipe 11. When the side cover 4 is opened, the bottom cover 5 is released simultaneously. This setting can avoid the failure risk of the traditional gear transmission structure under high temperature, and at the same time reduce mechanical linkage links to reduce the failure rate.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
