Description

Technical Field

[0001] The present invention relates to the technical field of fireproof rolling curtains, and in particular to a fuse structure with electronic triggering. Background Art

[0002] Fireproof rolling shutter is a fireproof and heat-insulating facility suitable for larger openings in buildings. The product is designed with a built-in roller and has a reasonable and compact structure. It is divided into ordinary and composite types according to the curtain plate type. The curtain surface of the fireproof rolling shutter is raised and lowered through a transmission device and a control system to play a role in fire prevention and fire isolation. The product has a smooth and beautiful appearance, novel shape, and strong steel. Fireproof rolling shutter doors are widely used in fire-proof partition areas of industrial and civil buildings. They can effectively prevent the spread of fire and protect life and property. They are indispensable fire protection facilities in modern buildings.

[0003] When a fire occurs in a building, the temperature often rises, and the fire shutter needs to be automatically closed when the temperature rises. Therefore, a fuse structure is provided. The temperature control release device generally uses a wire rope to pull the brake lever of the fire shutter rolling door machine, so that the brake pad of the fire shutter rolling door machine is separated from the transmission mechanism. The fire shutter slides down and closes by its own weight, closing the building flue, preventing the fire from spreading between the flues on each floor, reducing the impact of the fire, and buying time for people to escape.

[0004] The existing fuse structure with electronic triggering directly fixes the end of a steel wire on the pull rod, and the steel wire directly pulls the brake pull rod to trigger the fuse. This makes it impossible to adjust the sensing accuracy. Moreover, as fire shutters are becoming larger and larger, the fuse pulling force at the fire shutters needs to be larger. The pulling force of the steel wire can only be provided by the deformation tension of the thermal deformation material after reaching the predetermined temperature, resulting in unstable tension and unreliable fuse triggering.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient fuse structure with electronic triggering. Summary of the Invention

[0006] The purpose of the present invention is to provide a fuse structure with electronic triggering, in which the electromagnetic component adsorbs the magnetic plate to prevent the pop-up plate from popping out. When the fire triggers the fuse to blow, the electromagnetic component is powered off, and the pop-up plate pops out under the elastic force of the pop-up spring, providing a stable and large force to separate the brake pad from the transmission mechanism, and the fireproof roller shutter slides down and closes by its own weight. The fuse methods include mechanical fuse and electronic fuse, the brake pad thrust is stable, and the fuse triggering reliability is high.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A fuse structure with electronic triggering includes an induction unit and an actuator unit; the induction unit includes an electromagnetic component that generates magnetism when energized, a power supply unit for powering the electromagnetic component, and an induction unit electrically connected to the power supply unit; the actuator includes a magnetic plate, a pop-up plate connected to the magnetic plate, and a pop-up spring connected to the pop-up plate; the induction unit includes a contact induction unit and an electrical signal receiving induction unit; When the induction component receives the induction signal, the power supply component is powered off so that the electromagnetic component stops adsorbing the magnetic plate, and the pop-up plate pops out under the elastic force of the pop-up spring.

[0018] The beneficial effects of the electronically triggered fuse structure of the present invention are as follows: the electromagnetic component attracts the magnetic plate to prevent the pop-up plate from popping out; when a fire triggers the fuse to blow, the electromagnetic component is de-energized, and the pop-up plate pops out under the elastic force of the pop-up spring, providing a stable and large force to separate the brake pad from the transmission mechanism, allowing the fireproof roller shutter to slide down and close under its own weight, and the thrust of the brake pad is stable; The fusing methods include mechanical fusing and electronic fusing. Fusing can be triggered by temperature rise and deformation, by external force, or by active electrical signals and other electronic sensing elements. The fusing triggering reliability is high.

[0020] The following are specific embodiments of the present invention, which further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0021] 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 of modules and steps set forth in these embodiments and the steps do not limit the scope of the present invention.

[0022] At the same time, it should be understood that for the convenience of description, the processes in the drawings are not just performed individually, but multiple steps are performed in an intersecting manner.

[0023] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the product of the present invention is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0025] Technologies, methods, and systems known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0026] Example 1: Figures 1 to 2 The figure is only one embodiment of the present invention, which is a fuse structure with electronic triggering, including a sensing part and an actuator 3; the sensing part includes an electromagnetic member 2 for generating magnetism when energized, a power supply for supplying power to the electromagnetic member 2, and an sensing member electrically connected to the power supply; the actuator 3 includes a magnetic plate 33, an ejection plate 31 connected to the magnetic plate 33, and an ejection spring 32 connected to the ejection plate 31; the sensing member includes a contact sensing member 22 and an electrical signal receiving sensing member 23; In the present invention, when the induction component receives the induction signal, the power supply component is de-energized so that the electromagnetic component 2 stops adsorbing the magnetic plate 33. The pop-up plate 31 is popped out with a large force under the elastic force of the pop-up spring 32, thereby separating the brake pad of the rolling door machine from the transmission mechanism. The fireproof roller shutter slides down and closes by its own weight, sealing the building flue, preventing the fire from spreading between the flues on each floor, reducing the impact of the fire, and buying time for people to escape.

[0027] That is, the triggering method for the pop-up plate 31 in the present invention to pop up is magnetic demagnetization (or reduction of magnetic force), which is a new electronic triggering method. When the electromagnetic component 2 is energized, the magnetic force is greater than the elastic force of the pop-up spring 32, and the electromagnetic component 2 firmly adsorbs the magnetic plate 33. When the electromagnetic component 2 is powered off (or the power is reduced), the electromagnetic component is demagnetized (or the magnetic force is reduced), so that the magnetic force of the electromagnetic component 2 is less than the elastic force of the pop-up spring 32, and the electromagnetic component 2 cannot adsorb the magnetic plate 33, and the pop-up plate 31 pops out under the elastic force of the pop-up spring 32.

[0028] Moreover, the power supply component will be powered off (or the power supply will be reduced) only when the induction component receives the induction signal; wherein, the induction component includes a contact induction component 22 and an electrical signal receiving induction component 23, that is, the induction signal received by the induction component includes a contact signal and an electronic communication signal, and when any induction component receives the induction signal, the power supply component will be powered off (or the power supply will be reduced); it is further explained that the source of the fuse trigger signal also includes mechanical triggering and electronic triggering.

[0029] The present invention provides a fuse structure with electronic triggering. The electromagnetic component adsorbs the magnetic plate to prevent the pop-up plate from popping out. When a fire triggers the fuse to blow, the electromagnetic component is powered off, and the pop-up plate pops out under the elastic force of the pop-up spring, providing a stable and large force to separate the brake pad from the transmission mechanism. The fireproof roller shutter slides down and closes under its own weight. The fuse blowing methods include mechanical blowing and electronic blowing. The brake pad thrust is stable and the fuse triggering reliability is high.

[0030] Example 2, still as Figures 1 to 2 The figure shown is only one embodiment of the present invention. On the basis of the first embodiment, the present invention further comprises a mechanical triggering part 1 in a fuse structure with electronic triggering. The mechanical triggering part 1 comprises 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 sensing element 22.

[0031] When the temperature near the fire shutter door rises, the temperature-induced deformation element deforms, causing the fuse rope 11 to move, thereby causing the trigger block 12 to move until the first contact head 13 contacts the contact sensing component 22. The contact sensing component 22 feeds back the contact signal to the power supply component, and the pop-up block pops out.

[0032] That is, the melting is mechanically triggered by temperature rise and deformation.

[0033] In the present invention, a trigger spring 14 is provided on the side of the trigger block 12 away from the fuse rope 11. At room temperature, the temperature-increasing deformation element does not deform, causing the temperature-increasing deformation element to tighten the fuse rope 11. The fuse rope 11 just offsets the elastic force of the trigger spring 14, and the trigger block 12 does not move. When the temperature at the fireproof roller shutter rises, the temperature-increasing deformation element begins to lengthen, causing the fuse rope 11 to slowly loosen until the temperature reaches a preset threshold, generally 70 degrees Celsius. At this point, the fuse rope 11 loosens to a certain extent, and the trigger spring 14, under the action of its elastic force, pulls the trigger block 12 toward the side away from the fuse rope 11 by the target displacement amount, causing the first contact head 13 to contact the contact sensing element 22.

[0034] Of course, the number of the mechanical triggering part 1 is at least one; Generally speaking, fire shutter doors are located on the walls of the shopping mall's ventilation area. The temperature on both sides of the wall should be monitored. When high-temperature fire smoke occurs on either side, the fire shutter should be closed to block the spread of smoke and fire, giving people time to evacuate safely. Therefore, there should be two sets of temperature-increasing deformation elements located on both sides of the shutter wall for temperature detection, with two mechanical trigger parts 1; Alternatively, some supermarkets have fire shutters with long spans, which are generally multi-motor driven fire shutter doors with long bottom beam structures. This makes the spans of the fire shutters on both sides relatively large, which can reach more than ten meters. If only one side is provided with a temperature-increasing deformation element, there will be a safety hazard. Therefore, a temperature-increasing deformation element needs to be provided on each side of the fire shutter for temperature detection, with two mechanical triggering parts 1; Alternatively, a large supermarket has multiple interrelated fire shutters, and multiple shutter doors are distributed at intervals. In this case, at least one temperature-increasing deformation element should be provided at each fire shutter door for temperature detection, and multiple mechanical triggering parts 1 should be provided; It is understandable that there may be multiple mechanical triggering parts 1. When any temperature-increasing deformation element senses high temperature, the first contact head 13 of the mechanical triggering part 1 connected thereto will contact the contact sensing element 22, and the pop-up block will pop out.

[0035] That is, the electronically triggered fuse structure of the present invention can perform one-to-multi-point fusing control on fireproof roller shutters.

[0036] Example 3, still as Figures 1 to 3 The figure shown is only one embodiment of the present invention. Based on the second embodiment, the present invention has an electronically triggered fuse structure, which further includes a base plate 4 and a cover plate arranged on the base plate 4. At least a part of the sensing part and the execution part 3 are located between the base plate 4 and the cover plate.

[0037] An electromagnetic component fixing frame 21 for fixing the electromagnetic component 2 is provided on the bottom plate 4 , so that the position of the electromagnetic component 2 is stable.

[0038] Of course, a limiting plate 41 is provided on the bottom plate 4 , and a through hole is provided on the limiting plate 41 for facilitating the passage of the pop-up plate 31 .

[0039] It should be noted that the magnetic electromagnetic component is also convenient for resetting the actuator, that is, after the fire, the electromagnetic component 2 is powered on again and the magnetic plate 33 can be sucked back, and the repeated use stability is high.

[0040] Of course, some fireproof roller shutters require a larger pop-up stroke or a larger pop-up force (the elastic coefficient of the pop-up spring is large), which makes it impossible for the electromagnetic component 2 to reset. In this case, a reset motor 43 is required to drive the pop-up plate 31 to reset. A reset motor 43 is provided on the bottom plate 4 to drive the pop-up plate 31 to move.

[0041] Here, the base plate 4 is provided with a reset sensing component 42 electrically connected to the power supply component, and the pop-up plate 31 is provided with a second contact head 311 extending toward the reset sensing component 42. When the pop-up plate 31 is reset and displaced until the second contact head 311 contacts the reset sensing component 42, it indicates that the magnetic plate 33 is in contact with the electromagnetic component 2 for stable adsorption.

[0042] Of course, the reset induction element and the induction element are both electrically connected to the power supply element through the controller.

[0043] The controller is electrically connected to a wireless communication component 24. In a large-bottom-beam fireproof roller shutter with a longer span, multiple roller shutter door motors that are synchronously controlled to rise and fall are provided, so there should also be multiple fuse structures. In the event of a fire, multiple fuse structures need to be triggered and blown at the same time, and multiple roller shutter door motors need to cause the fireproof roller shutter to fall down at the same time; therefore, the wireless communication components 24 in the multiple fuse structures are electrically connected to each other, so that when any fuse structure is triggered and blown, the other fuse structures are also triggered and blown.

[0044] Example 4, as Figures 1 to 3 The figure shown is only one embodiment of the present invention. Based on any of the above embodiments, in a fuse structure with electronic triggering of the present invention, a signal interface disk 5 electrically connected to the electrical signal receiving induction component 23 is provided on the base plate 4, and a plurality of communication interfaces are provided on the signal interface disk 5, which can be a wired interface or a wireless interface.

[0045] The signal interface disk 5 can trigger the fuse through active electrical signals and other electronic sensing elements, and the fuse triggering reliability is high; specific signals include: active fuse signals sent by the control center, fire emergency signals sent by the fire center, emergency self-test signals of fireproof roller shutters on the wall, active protection signals sent by control buttons on the wall, etc.

[0046] The beneficial effects of the fuse structure with electronic triggering of the present invention are: the electromagnetic component adsorbs the magnetic plate to prevent the pop-up plate from popping out, and when the fire triggers the fuse to blow, the electromagnetic component is powered off, and the pop-up plate pops out under the elastic force of the pop-up spring, providing a stable and large force to separate the brake pad from the transmission mechanism, and the fireproof roller shutter slides down and closes by its own weight. The fuse methods include mechanical fuse and electronic fuse, the brake pad thrust is stable, and the fuse triggering reliability is high.

[0047] Example five is only one of the embodiments of the present invention. On the basis of any of the above embodiments, the present invention also provides a fusing control method of a fuse structure with electronic triggering, wherein a fuse structure with electronic triggering is provided at each of the several motors on the same bottom beam fireproof roller shutter; the fuses at the several motors on the same bottom beam fireproof roller shutter are electrically connected; before the fireproof roller shutter is blown, the electromagnetic parts in the fuse adsorb the fuse plate; when any fuse receives a fusing signal, the electromagnetic parts in all fuses electrically connected to the fuse stop adsorbing the fuse plate, and the fuse plate pops out to close the fireproof roller shutter.

[0048] The lower end of a large fireproof roller shutter has a very long bottom beam, which can be ten meters or even more in length. The fireproof roller shutter and the bottom beam are very heavy, and it is impossible to be driven by a single motor for lifting and lowering. Generally, multiple motors are connected to the same bottom beam to complete the lifting and lowering drive of this large fireproof roller shutter. The most common ones are 3-link (3 motors connected to the same bottom beam) and 5-link (5 motors connected to the same bottom beam). Let's take the common 5-link motor as an example. There are 5 motors on the fireproof roller shutter with the same bottom beam, and each motor is equipped with a fuse, that is, there are 5 fuses in total, and the structure of each fuse is the same.

[0049] When any fuse is blown, after signal communication, all fuses are blown at the same time, which can ensure that the bottom beam can descend at the same time and prevent damage to the bottom beam and fire rolling door.

[0050] The present invention is not limited to the above specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the present invention.
