Description

Technical Field

[0001] This utility model relates to the field of fireproof roller shutter technology, and in particular, it relates to a structure of a fireproof roller shutter fuse with electronic triggering. Background Technology

[0002] Fire-resistant roller shutters are fire-resistant and heat-insulating facilities suitable for large openings in buildings. The product features a concealed roller shaft design, resulting in a rational and compact structure. Based on the type of curtain panel, they are divided into ordinary and composite types. The fire-resistant roller shutter curtain is raised and lowered via a transmission device and control system, achieving fire prevention and fire isolation. The product has a flat and beautiful appearance, novel design, and high rigidity. Fire-resistant roller shutter doors are widely used in fire-resistant partitions in industrial and civil buildings, effectively preventing the spread of fire and protecting life and property. They are an indispensable fire protection facility in modern buildings.

[0003] When a fire occurs inside a building, a temperature rise is often generated, requiring fire-resistant roller shutters to automatically close when the temperature rises. This is where the fire-resistant roller shutter fuse structure comes in. The temperature control release device generally uses a steel wire rope to pull the brake rod of the fire-resistant roller shutter motor, causing the brake pads of the fire-resistant roller shutter motor to separate from the transmission mechanism. The fire-resistant roller shutter then slides down and closes by its own weight, sealing off the building's smoke duct, preventing fire from spreading between floors, reducing the impact of the fire, and buying time for people to escape.

[0004] Existing electronically triggered fireproof roller shutter fuses all use a structure where the end of a steel wire is directly fixed to a pull rod. The wire pulls the brake rod to trigger the fuse, which makes it impossible to adjust the sensing accuracy. Moreover, as fireproof roller shutters become larger, the fuse pulling force required at the shutter needs to be greater. The force required to pull the steel wire can only be provided by the deformation of the heat-deformable material after reaching a predetermined temperature, resulting in unstable pulling force and unreliable fuse triggering.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient fireproof roller shutter fuse structure with electronic triggering. Utility Model Content

[0006] The purpose of this utility model is to provide a fireproof roller shutter fuse structure with electronic triggering. The electromagnetic component attracts the magnetic plate to prevent the pop-out plate from popping out. In the event of a fire, the electromagnetic component is de-energized, and the pop-out plate pops out under the elastic force of the pop-out spring. This provides a stable and large force to separate the brake pad from the transmission mechanism, and the fireproof roller shutter closes by sliding down under its own weight. The fuse method includes mechanical fuse and electronic fuse. The brake pad thrust is stable, and the fuse triggering reliability is high.

[0007] To achieve the above objectives, this utility model employs the following technical solution:

[0011] As a preferred embodiment of the present invention, it further includes a base plate and a cover plate disposed on the base plate, wherein at least a portion of both the sensing part and the actuating part is located between the base plate and the cover plate.

[0012] As a preferred embodiment of this utility model, a limiting plate is provided on the base plate, and the limiting plate is provided with a through hole for facilitating the passage of the pop-out plate.

[0013] As a preferred embodiment of this utility model, the base plate is provided with a reset sensor that is electrically connected to the power supply component, and the pop-out plate is provided with a second contact head extending toward the reset sensor.

[0015] As a preferred embodiment of this invention, the base plate is provided with a reset motor for driving the displacement of the pop-out plate.

[0021] The following are specific embodiments of the present invention, which further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement and steps of the modules and steps set forth in these embodiments do not limit the scope of the present invention.

[0023] At the same time, it should be understood that, for ease of description, the process shown in the attached diagram is not performed in isolation, but rather involves multiple steps that overlap.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and systems known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0027] Example 1: As Figures 1 to 2 The diagram shown is merely one embodiment of this utility model. A fireproof roller shutter fuse structure with electronic triggering includes a triggering part 1, a sensing part, and an execution part 3. The sensing part includes an electromagnetic component 2 that generates magnetism when energized, a power supply component for supplying power to the electromagnetic component 2, and a sensing component electrically connected to the power supply component. The execution part 3 includes a magnetic plate 33, a pop-out plate 31 connected to the magnetic plate 33, and a pop-out spring 32 connected to the pop-out plate 31. The sensing component includes a contact sensing component 22 and an electrical signal receiving sensing component 23. The triggering part 1 includes a fuse rope 11 and a trigger block 12 connected to the fuse rope 11. The trigger block 12 is provided with a first contact head 13 extending towards the contact sensing component 22. The triggering part 1 also includes a signal interface disk 5 for connecting to the electrical signal receiving sensing component 23.

[0028] In this utility model, the sensing element is a "switch" that powers the electromagnetic element 2. When the sensing element receives a sensing signal, the power supply element cuts off the power, causing the electromagnetic element 2 to stop attracting the magnetic plate 33. The pop-out plate 31 pops out with a large force under the elastic force of the pop-out spring 32, thereby separating the brake pad of the rolling door motor from the transmission mechanism. The fireproof rolling shutter slides down and closes by its own weight, sealing the building's smoke duct, preventing fire from spreading between floors, reducing the impact of the fire, and buying time for people to escape.

[0029] The pop-out plate 31 in this utility model is triggered by magnetic attraction and demagnetization, which is a brand-new electronic triggering method. When the electromagnetic component 2 is energized, the magnetic force is greater than the elastic force of the pop-out spring 32, and the electromagnetic component 2 firmly attracts the magnetic plate 33. When the electromagnetic component 2 is de-energized, the electromagnetic component is demagnetized, so that the magnetic force of the electromagnetic component 2 is less than the elastic force of the pop-out spring 32, and the electromagnetic component 2 can no longer attract the magnetic plate 33. The pop-out plate 31 pops out under the elastic force of the pop-out spring 32.

[0030] The present invention discloses a fireproof roller shutter fuse structure with electronic triggering, which further includes a triggering part 1. The triggering part 1 includes a fuse rope 11 and a triggering block 12 connected to the fuse rope 11. The triggering block 12 is provided with a first contact head 13 extending toward the contact sensor 22.

[0031] When the temperature rises near the fireproof rolling shutter door, the deformation of the heating deformation element causes the fuse rope 11 to shift, which in turn causes the trigger block 12 to shift until the first contact head 13 contacts the contact sensor 22. The contact sensor 22 then feeds back the contact signal to the power supply unit, and the pop-out block pops out.

[0032] That is, mechanical triggering of the fuse through temperature rise and deformation.

[0033] This utility model discloses a fireproof roller shutter fuse structure with electronic triggering. The electromagnetic component attracts the magnetic plate to prevent the pop-out plate from popping out. When the fire triggers the fuse, the electromagnetic component is de-energized, and the pop-out plate pops out under the elastic force of the pop-out spring. This provides a stable and large force to separate the brake pad from the transmission mechanism, and the fireproof roller shutter closes by sliding down under its own weight. The fuse method includes mechanical fuse and electronic fuse. The brake pad thrust is stable, and the fuse triggering reliability is high.

[0034] Example 2, still as Figures 1 to 2 As shown, this is only one embodiment of the present invention. Based on Embodiment 1, the power supply component is de-energized only when the sensing element receives the sensing signal. The sensing element includes a contact sensing element 22 and an electrical signal receiving sensing element 23. That is to say, the sensing signal received by the sensing element includes contact signals and electronic communication signals. When either sensing element receives the sensing signal, the power supply component will de-energize. Furthermore, the fuse trigger signal source also includes mechanical triggering and electronic triggering.

[0035] In this invention, a trigger spring 14 is provided on the side of the trigger block 12 away from the fusible rope 11. With the trigger spring 14 on the side of the trigger block 12 away from the fusible rope 11, at room temperature, the heating deformation element does not deform, causing it to tighten the fusible rope 11. The fusible rope 11 just counteracts the elastic force of the trigger spring 14, and the trigger block 12 does not shift. When the temperature at the fireproof roller shutter rises, the heating deformation element begins to lengthen, causing the fusible rope 11 to gradually loosen until the temperature reaches a preset threshold, typically 70 degrees Celsius. At this point, the fusible rope 11 loosens to a certain extent, and the trigger spring 14, under its elastic force, pulls the trigger block 12 away from the fusible rope 11 by the desired displacement, causing the first contact head 13 to contact the contact sensor 22.

[0036] Of course, the number of trigger units 1 is at least one;

[0037] Generally, fireproof roller shutters are located on the walls of ventilated areas in shopping malls. Temperature should be monitored on both sides of the wall. If there is high temperature and smoke on either side during a fire, the fireproof roller shutter should close to block the spread of smoke and fire, and buy time for people to evacuate safely. Therefore, there should be two sets of temperature-sensing deformation elements located on both sides of the roller shutter wall for temperature detection, with two triggering parts 1.

[0038] Alternatively, some shopping malls have fireproof roller shutters with long spans, which are generally fireproof roller shutters with a long bottom beam structure driven by multiple motors. This results in a large span on both sides of the fireproof roller shutter, which can reach more than ten meters. If only one side is equipped with a heating deformation element, there is a safety hazard. Therefore, it is necessary to install a heating deformation element on each side of the fireproof roller shutter for temperature detection, with two triggering parts 1.

[0039] Alternatively, if a large shopping mall has multiple interconnected fireproof roller shutters with multiple roller shutter doors spaced apart, then at least one heating deformation element with multiple triggering parts should be installed at each fireproof roller shutter door for temperature detection.

[0040] It is understandable that there can be multiple triggering parts 1. When any heating deformation element senses a high temperature, the first contact head 13 of the triggering part 1 connected to it will contact the contact sensing element 22, and the pop-out block will pop out.

[0041] This utility model discloses a fireproof roller shutter fuse structure with electronic triggering, which can control the fireproof roller shutter fuse from one point to multiple points.

[0042] Example 3, still as Figures 1 to 2 As shown, this is only one embodiment of the present invention. Based on embodiment two, the present invention provides a fireproof roller shutter fuse structure with electronic triggering, which further includes a base plate 4 and a cover plate disposed on the base plate 4. At least a portion of the sensing part and the execution part 3 are located between the base plate 4 and the cover plate.

[0043] An electromagnetic component fixing bracket 21 is provided on the base plate 4 for fixing the electromagnetic component 2, and the electromagnetic component 2 is in a stable position.

[0044] Of course, a limiting plate 41 is provided on the base plate 4, and the limiting plate 41 is provided with a through hole for the pop-out plate 31 to pass through.

[0045] It should be noted that the magnetically attached electromagnetic component also facilitates the reset of the actuator. That is, after a fire, when the electromagnetic component 2 is powered on again, the magnetic plate 33 can be attracted back, and the device can be reused with high stability.

[0046] Of course, some fireproof roller shutters require a large pop-out stroke or a large pop-out force, which makes it impossible for the electromagnetic component 2 to reset. In this case, the reset motor 43 is required to drive the pop-out plate 31 to reset. The base plate 4 is provided with a reset motor 43 for driving the pop-out plate 31 to move.

[0047] Here, a reset sensor 42 electrically connected to the power supply component is provided on the base plate 4, and a second contact head 311 extending toward the reset sensor 42 is provided on the pop-out plate 31. When the pop-out plate 31 resets and moves until the second contact head 311 contacts the reset sensor 42, it indicates that the magnetic plate 33 is in contact with the electromagnetic component 2 and is stably attracted.

[0048] Of course, both the reset sensor and the sensor are electrically connected to the power supply via a controller, which is a PCB board.

[0049] Example 4, as Figures 1 to 2As shown, this is only one embodiment of the present invention. Based on any of the above embodiments, in the electronically triggered fuse structure of the present invention, the base plate 4 is provided with a signal interface disk 5 electrically connected to the electrical signal receiving induction element 23. The signal interface disk 5 is provided with multiple communication interfaces, which can be wired interfaces or wireless interfaces.

[0050] The signal interface panel 5 can be triggered to blow the fuse by active electrical signals and other electronic sensing elements, and the fuse triggering reliability is high. Specific signals include: active fuse blowing signals sent by the control center, fire emergency signals sent by the fire protection center, emergency self-test signals of the fireproof roller shutter on the wall, active protection signals sent by the control buttons on the wall, etc.

[0051] This utility model discloses a fireproof roller shutter fuse structure with electronic triggering. The electromagnetic component attracts the magnetic plate to prevent the pop-out plate from popping out. In the event of a fire, the electromagnetic component is de-energized, and the pop-out plate pops out under the elastic force of the pop-out spring. This provides a stable and large force to separate the brake pad from the transmission mechanism, and the fireproof roller shutter closes by sliding down under its own weight. The fuse method includes mechanical fuse and electronic fuse. The brake pad thrust is stable, and the fuse triggering reliability is high.

[0052] This utility model is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this utility model should be included within the protection scope of this utility model.
