Description

Technical Field

[0001] This utility model belongs to the field of roller shutter technology, and specifically relates to a fireproof roller shutter door. Background Technology

[0002] Currently, roller shutters, as a type of door structure consisting of multiple articulated movable door panels connected together and opening and closing along a fixed track with the top roller as the center, are widely used in various scenarios such as industrial plants, commercial shops, underground garages, and logistics warehouses due to their simple operation, small footprint, and high opening and closing efficiency. They have become an indispensable security and partition facility in production, operation, and daily life. As people's requirements for user experience increase, the noise problem during the operation of roller shutters has gradually attracted attention. In the opening and closing stages of traditional roller shutters, the rigid friction between the door panels and the guide rail, as well as the collision caused by the shaking of the door in strong winds, not only generate obvious noise, interfering with the surrounding environment and people's activities, but also aggravate the wear of components such as door panels, guide rails, and roller magazines, resulting in increased component clearance, decreased structural stability, and directly shortening the overall service life of the roller shutter. Therefore, the development of roller shutters with silent function has become one of the important directions for industry improvement. To address the noise issue, relevant technical fields have proposed targeted improvement solutions. For example, Chinese utility model patent CN206845050U discloses a novel silent roller shutter door. This solution reduces noise to a certain extent by installing a noise-reducing device in a ground-fixed groove directly below the roller shutter door compartment, combined with the coordinated design of the roller shutter door motor, roller shaft, door panels, and guide rails. It also simplifies operation and controls manufacturing costs, demonstrating some practicality. However, in actual application scenarios, especially in industrial plants, warehouses, and other areas with fire hazards, such silent roller shutter doors still have significant functional defects: their overall structural design focuses on noise reduction and basic opening and closing functions, lacking high-strength fire-resistant design for fire scenarios; the door panels are mostly made of ordinary metal or composite materials without integrated fire-resistant and heat-insulating layers; and the sealing structure between the guide rails and roller shaft compartment is also inadequate. Considering the fireproofing requirements in high-temperature environments, when a fire occurs, high-temperature flames can easily spread through gaps in the door panels. The door itself is also unable to withstand prolonged high-temperature baking, failing to form an effective fire barrier and thus failing to prevent the spread of fire. This could lead to increased property damage and escalated safety risks. It is evident that while existing roller shutters have achieved optimization in terms of noise reduction, their fire resistance performance is significantly insufficient, failing to meet the dual requirements of "quiet operation" and "fire safety" in industrial and warehousing scenarios. With the continuous improvement of fire safety standards and the increasing demands of users for multi-functional integration of equipment, the development of a new type of roller shutter that can maintain low-noise operation, reduce component wear, and possess high-strength fireproof and heat-insulating performance, effectively blocking the spread of fire, has become an urgent need for the current industry development. This is of great significance for improving the comprehensive applicability and safety assurance capabilities of roller shutters. Utility Model Content

The fire prevention mechanism includes a rear housing, which is fixedly installed on the bottom rear side of the top plate. A second take-up roller is rotatably connected inside the rear housing. A fireproof curtain is wrapped around the outer surface of the second take-up roller. The fireproof curtain is specifically configured as a curtain made of basalt fiber material. A second motor is fixedly installed on one side of the rear housing. The output end of the second motor passes through the rear housing and is fixedly connected to one side of the second take-up roller. A spray fire prevention component is fixedly installed between the bottom of the rear housing and the bottom of the front housing.

[0005] As a preferred technical solution, front support rails are fixedly installed on both sides of the bottom of the front housing, and front support blocks are slidably connected inside the front support rails. The inner side of the front support blocks is connected to the lower ends of both sides of the roller shutter door body.

[0006] As a preferred technical solution, rear support rails are fixedly installed on both sides of the bottom of the rear housing, and rear support blocks are slidably connected inside the rear support rails. The inner side of the rear support blocks is connected to the lower ends of both sides of the fireproof curtain.

[0007] As a preferred technical solution, a load-bearing shaft is fixedly installed between the inner sides of the rear support block, the top of the load-bearing shaft is fixedly connected to the bottom of the fireproof curtain, and the mounting hole is set as a countersunk hole.

[0008] As a preferred technical solution, a circular groove is provided in the middle of the back side of the rear housing, and a fire sensor is fixedly installed inside the circular groove.

[0009] As a preferred technical solution, a chassis is fixedly installed on one side of the back of the rear housing, a controller is provided inside the chassis, and a display screen is provided on the upper side of the back of the chassis.

[0010] As a preferred technical solution, the fire sprinkler assembly includes a water supply pipe, which is fixedly installed between the inner sides of the front and rear housings. Fire-resistant water supply nozzles are fixedly installed at equal intervals in a linear arrangement at the bottom of the water supply pipe.

A water supply solenoid valve is fixedly installed at one end of the fire-resistant water supply nozzle, and an external water pipe connection flange is fixedly installed at the outer end of the water supply solenoid valve.

[0011] In summary, the present invention has the following main advantages: First, during the application of this technical solution, by setting up a roller shutter door opening and closing mechanism and a stable installation structure, the roller shutter door body can be opened and closed smoothly in normal non-fire scenarios. The cooperation between the front support rail and the front support block ensures that the roller shutter door body moves along a fixed track, avoiding deviation and jamming. The design of the mounting holes on the top plate ensures that the device is installed stably as a whole without affecting the flatness of the installation surface. At the same time, the fireproof mechanism is in standby mode and does not interfere with normal use. Thus, it achieves the effect of meeting daily passage and partition needs and reducing component wear, solving the problems of unsmooth opening and closing, poor installation stability, and short service life caused by easy wear of components in the existing technology of traditional roller shutter doors. Secondly, during the application of this technical solution, by setting up an automatically responding fire prevention mechanism and sprinkler components, dual protective actions can be quickly triggered when a fire occurs. After the fire sensor detects the fire, it transmits a signal to the controller. The controller simultaneously activates the lowering of the fire curtain and the sprinkler cooling. The fire curtain forms an effective fire barrier, and the sprinkler components cool the fire curtain and suppress the spread of high temperature. At the same time, the controller monitors the status in real time and feeds back information through the display screen, thereby achieving the effects of timely blocking of the fire, enhancing the fire prevention effect, and facilitating abnormal handling. This solves the problems of insufficient fire resistance of roller shutter doors, delayed fire response, and lack of active cooling protection in existing technologies, which lead to the inability to effectively prevent the spread of fire.

[0014] Example

[0015] refer to Figures 1 to 5 A fireproof roller shutter door according to this embodiment includes a top plate 1, a front housing 2 fixedly installed on the bottom front side of the top plate 1, a first winding roller 3 rotatably connected inside the front housing 2, a first motor 4 fixedly installed on one side of the front housing 2, the output end of the first motor 4 and one end of the first winding roller 3 fixedly connected, the roller shutter door body 5 is wound on the outer surface of the first winding roller 3, a fireproof mechanism 6 is fixedly installed on the bottom rear side of the top plate 1, and mounting holes 7 are provided at the four corners of the top plate 1. The fire protection mechanism 6 includes a rear housing 61, which is fixedly installed on the bottom rear side of the top plate 1. A second take-up roller 62 is rotatably connected inside the rear housing 61. A fireproof curtain 63 is wound around the outer surface of the second take-up roller 62. The fireproof curtain 63 is specifically made of basalt fiber material. A second motor 64 is fixedly installed on one side of the rear housing 61. The output end of the second motor 64 passes through the rear housing 61 and is fixedly connected to one side of the second take-up roller 62. A sprinkler fire protection assembly 6 is fixedly installed between the bottom of the rear housing 61 and the bottom of the front housing 2. 5. During the application of this device, in normal fire-free scenarios, when it is necessary to open or close the roller shutter door body 5, the first motor 4 is started. The output end of the first motor 4 drives the first winding roller 3 inside the front housing 2 to rotate. During the rotation of the first winding roller 3, the roller shutter door body 5 that is rolled up on its outer surface is retracted or expanded, realizing the normal opening and closing of the door. This process does not require any additional complicated operations, is highly convenient to operate, and can meet the basic needs of daily passage and partition. When a fire occurs, the fire prevention mechanism 6 quickly enters the working state and starts the second motor 6. 4. The output end of the second motor 64 passes through the rear housing 61 and drives the second take-up roller 62 inside the rear housing 61 to rotate. The rotation of the second take-up roller 62 releases the fireproof curtain 63 wrapped around its outer surface. Due to its own structural characteristics, the fireproof curtain 63 can form an effective fire barrier after unfolding. Since the fireproof curtain 63 is made of basalt fiber, which has excellent high temperature resistance, it can effectively block the penetration and spread of flames, greatly improving the fire protection effect. At the same time, the spray fireproof component 65 between the bottom of the rear housing 61 and the bottom of the front housing 2 is activated. The spray fireproof component 65 can spray the fireproof curtain 63 and the surrounding area. On the one hand, it cools down the fireproof curtain 63 to prevent it from being damaged by prolonged high temperature baking and prolongs the effective protection time of the fireproof curtain 63. On the other hand, it can inhibit the spread of the high temperature generated by the fire to the other side, further strengthening the fireproof barrier effect. Compared with the existing structure that only relies on a single door, this device forms a double fire protection through the synergistic effect of the fireproof curtain 63 and the spray fireproof component 65, which significantly improves the ability to deal with fires and better protects the safety of people and property.

[0016] refer to Figures 1-3 and Figure 5A circular groove 69 is provided in the middle of the back of the rear housing 61. A fire sensor 610 is fixedly installed inside the groove 69. A housing 611 is fixedly installed on one side of the back of the rear housing 61. A controller is located inside the housing 611. A display screen 612 is provided on the upper side of the back of the housing 611. The sprinkler fireproof assembly 65 includes a water supply pipe 651, which is fixedly installed between the inner sides of the front housing 2 and the rear housing 61. Fireproof water supply nozzles 652 are fixedly installed at equal intervals in a linear arrangement at the bottom of the water supply pipe 651. The fire-resistant water supply nozzle 652 is inclined towards the fire curtain 63. A water supply solenoid valve 653 is fixedly installed at one end of the nozzle, and an external water pipe connection flange 654 is fixedly installed at the outer end of the solenoid valve 653. During the operation of this device, the fire sensor 610, located in the circular groove 69 in the middle of the back of the rear housing 61, can monitor fire signals in the surrounding environment in real time. Once a fire is detected, it quickly transmits the signal to the controller inside the chassis 611 on one side of the rear housing 61, preventing delays in fire response due to untimely detection and gaining valuable time for subsequent fire prevention actions. After receiving the signal, the controller will, on the one hand, feed back the fire information and the operating status of the device to the display screen 612 on the upper side of the back of the chassis 611, allowing the operator to intuitively grasp the situation on site and facilitate timely auxiliary response measures. On the other hand, it will simultaneously trigger the start of the sprinkler fire prevention component 65. At this time, the water supply solenoid valve 653 at one end of the water supply pipe 651 will open, and the external water pipe will supply water to the water supply pipe 651 through the external water pipe connecting flange 654. The water supply pipe 651 will stably deliver water to the fire prevention water supply nozzles 652 arranged linearly at equal intervals at the bottom. Due to the fire prevention... The water supply nozzles 652 are tilted towards the fire curtain 63, and the sprayed water can accurately cover the surface of the fire curtain 63. This not only cools the fire curtain 63, preventing it from losing its fire resistance due to prolonged high temperature baking and extending the effective protection time of the fire curtain 63, but also inhibits the spread of high temperature generated by the fire to the other side of the fire curtain 63, further enhancing the fire barrier effect. At the same time, the evenly arranged nozzle design ensures that the water flow covers no dead corners, avoiding local areas from failing to provide fire protection due to lack of water. This comprehensively improves the device's ability to respond to fires and better protects the safety of the protected area.

[0017] refer to Figures 1-4The front housing 2 has front support rails 8 fixedly installed on both sides of its bottom. Front support blocks 9 are slidably connected inside each front support rail 8. The inner side of each front support block 9 is connected to the lower ends of both sides of the roller shutter body 5. The rear housing 61 has rear support rails 66 fixedly installed on both sides of its bottom. Rear support blocks 67 are slidably connected inside each rear support rail 66. The inner side of each rear support block 67 is connected to the lower ends of both sides of the fireproof curtain 63. A load-bearing shaft 68 is fixedly installed between the inner sides of each rear support block 67. The top of the load-bearing shaft 68 is connected to the fireproof curtain 63. The bottom is fixedly connected, and the mounting hole 7 is a countersunk hole. During the application of this device, when the roller shutter door body 5 is opened or closed, the front support block 9 will slide synchronously inside the front support rail 8 as the roller shutter door body 5 moves. The front support rail 8 provides a stable moving path for the front support block 9, preventing the roller shutter door body 5 from shifting left or right or swaying when moving up and down, ensuring that the door always runs smoothly along the preset trajectory, effectively reducing friction between the roller shutter door body 5 and the surrounding structure, reducing component wear, and extending the service life of the door; when the fire curtain 6 3. When unfolding or retracting, the rear support block 67 slides inside the rear support rail 66 as the fire curtain 63 moves. The rear support rail 66 guides and limits the movement of the rear support block 67, preventing the fire curtain 63 from shifting during movement and ensuring that the fire curtain 63 accurately covers the protected area, thus ensuring the integrity of the fireproof partition in the event of a fire. At the same time, the load-bearing shaft 68 between the inner sides of the rear support blocks 67 provides a stable downward pulling force to the fire curtain 63 during its lowering process, preventing the fire curtain 63 from shifting. To prevent jamming or wrinkling due to wind or other external forces, the fire curtain 63 must be deployed quickly and smoothly to improve the timeliness of fire response. In addition, the mounting holes 7 at the four corners of the top plate 1 are countersunk holes, so that the bolt heads can be fully embedded in the holes during installation and will not protrude from the surface of the top plate 1. This ensures the overall flatness after installation, prevents the bolt heads from scratching surrounding objects, enhances the stability of the installation structure, prevents loosening during long-term use, and further ensures the overall stability and safety of the device.

[0018] Operating principle and advantages: During application, in normal fire-free scenarios, this device mainly achieves normal opening and closing functions through the roller shutter door body 5. When it is necessary to open or close the roller shutter door body 5, the first motor 4 is started first. Through the power transmission at the output end of the first motor 4, the first winding roller 3 inside the front housing 2 is driven to rotate. During the rotation of the first winding roller 3, the roller shutter door body 5 is wound up and down on its outer surface. During this process, the front support blocks 9 connected to the lower ends of both sides of the roller shutter door body 5 will slide synchronously inside the front support rail 8. By setting the front support rail 8, a stable sliding guide is provided for the front support blocks 9, while the front support blocks 9 can limit the movement direction of the roller shutter door body 5, ensuring that the roller shutter door body 5 moves up and down along a fixed trajectory. To prevent deviation during operation and ensure smooth opening and closing, the top plate 1 has mounting holes 7 at its four corners. These mounting holes 7 are countersunk and can be used to fix the entire device in the preset installation position, ensuring the overall installation is stable without affecting the flatness of the installation surface. During this stage, the fireproof mechanism 6 is in standby mode. The second motor 64 is not started, the second winding roller 62 inside the rear housing 61 remains stationary, the fireproof curtain 63 is wound up on the outer surface of the second winding roller 62, and the rear support block 67 is stationary inside the rear support rail 66. The entire fireproof mechanism 6 will not interfere with the normal use of the roller shutter door body 5, thus enabling it to stably meet the needs of daily passage and partition. When a fire occurs, the fire sensor 610 of this device first enters the working state. The fire sensor 610 is installed in the circular groove 69 in the middle of the back of the rear housing 61. It can detect fire signals in the surrounding environment in real time. Once a fire is detected, it will transmit the signal to the housing 611 on one side of the back of the rear housing 61. The housing 611 is equipped with a controller. After receiving the fire signal, the controller immediately activates a dual response mechanism. On the one hand, the controller controls the display screen 612 on the upper side of the back of the housing 611 to operate, so that the display screen 612 displays the fire alarm information, so that the operator can know the fire situation in time and take countermeasures. On the other hand, the controller simultaneously starts the second motor 64 and the water supply solenoid valve 653 in the sprinkler fire prevention component 65. Through this automatic response design, the timeliness of fire response is ensured, which solves the problem of delayed response caused by the reliance on manual activation of fire prevention measures in existing roller shutter doors. Subsequently, the output of the second motor 64... The fire curtain 63 is connected to the second take-up roller 62 through the rear housing 61 and drives the second take-up roller 62 inside the rear housing 61 to rotate. During the rotation, the second take-up roller 62 releases the fire curtain 63 wrapped around its outer surface. The rear support blocks 67 connected to the lower ends of both sides of the fire curtain 63 will slide inside the rear support rail 66. By setting the rear support rail 66, the rear support blocks 67 are provided with sliding guidance. The rear support blocks 67 restrict the movement direction of the fire curtain 63. At the same time, a load-bearing shaft 68 is fixedly installed between the inner sides of the rear support blocks 67. The load-bearing shaft 68 drives the fire curtain 63 to descend stably by its own weight, avoiding the fire curtain 63 from shifting or getting stuck due to wind or other external forces during the descent, until the fire curtain 63 is fully unfolded to form a fireproof partition. Since the fire curtain 63 is made of basalt fiber material, which has excellent high temperature resistance, it can effectively block the spread of flames and solve the problem that the existing silent roller shutter door lacks high-strength fireproof design and cannot block the spread of fire. As the fire curtain 63 unfolds, the sprinkler fire suppression assembly 65 of this device is simultaneously activated. The sprinkler fire suppression assembly 65 includes a water supply pipe 651, fire suppression water supply nozzles 652, a water supply solenoid valve 653, and an external water pipe connection flange 654. After the water supply solenoid valve 653 is activated, the external water pipe is connected to the water supply pipe 651 through the external water pipe connection flange 654, supplying water to the water supply pipe 651. The water supply pipe 651 is fixedly installed between the inner sides of the front housing 2 and the rear housing 61, and can stably deliver water to the fire suppression water supply nozzles 652 at the bottom. The fire suppression water supply nozzles 652 are arranged linearly at equal intervals and are inclined towards the fire curtain 63. Through this layout design, the fire suppression water supply nozzles are able to provide stable water supply to the fire curtain 652. The water spray nozzle 652 can precisely spray water onto the surface of the fireproof curtain 63, cooling it down and preventing damage from prolonged high-temperature baking. This further enhances the fireproof effect and also inhibits the spread of high temperatures from a fire to the other side, overcoming the deficiency of existing roller shutters that lack active cooling fireproof structures. During this process, the controller also monitors the lowering status of the fireproof curtain 63 and the water supply status of the sprinkler fireproof component 65 in real time. If any abnormalities occur, such as obstruction of the lowering of the fireproof curtain 63 or interruption of water supply, the controller will immediately control the display screen 612 to display fault information, allowing operators to promptly identify and handle problems, ensuring the stable implementation of fireproof functions and guaranteeing the fireproof partition. The completeness of the design is evident. This technical solution, through a phased operational design, achieves a balance between daily use and fire prevention. In the daily operation phase, the coordinated work of the roller shutter body 5, the first motor 4, the first winding roller 3, the front support rail 8, and the front support block 9 meets the need for convenient opening and closing. In the fire phase, the cooperation of the fire-resistant mechanism 6 and the sprinkler assembly forms multiple fire protection measures. The fire-resistant mechanism 6 includes the rear housing 61, the second winding roller 62, the fire curtain 63, the second motor 64, the rear support rail 66, the rear support block 67, and the load-bearing shaft 68. Through the coordinated operation of these structures, the overall performance of the device is further enhanced. The front support rail 8, the front support block 9, and the rear support rail 66... The sliding cooperation with the rear support block 67 ensures the stable movement of the roller shutter door body 5 and the fireproof curtain 63 respectively. The load shaft 68 ensures the stable lowering of the fireproof curtain 63. The fire sensor 610 and the controller realize automatic response. The sprinkler assembly enhances the fireproof effect. These designs together solve the problems of fast wear and short service life of traditional roller shutter doors and insufficient fireproof performance of existing silent roller shutter doors in the background technology. This makes the device able to play a stable role in various scenarios such as industrial plants, commercial shops, and underground garages, taking into account both ease of use and safety. During the application of this device, its controller integrates a remote information transmission alarm module, specifically a WIFI module for remote information transmission alarm. In this technical solution, both the first motor 4 and the second motor 64 are three-phase asynchronous motors with a power range of 0.75kW-2.2kW, a rated voltage of 380V, a rated speed of 1400r / min-2800r / min, and an IP54 protection rating; the first winding roller 3 and the second winding roller 62 have diameters ranging from 80mm to 150mm, and their lengths are adapted to the width of the roller shutter body 5 and the fireproof curtain 63.
