Technical Field
[0001] This utility model relates to the field of fire alarm technology, specifically a fire alarm with multi-angle high-intensity light output. Background Technology
[0002] Fire alarms with sound and light are crucial devices in fire protection systems, integrating audible and visual warnings. When the automatic fire alarm system detects a fire, it quickly emits a loud, piercing buzzing or alarm sound, typically exceeding 85 decibels, ensuring clear visibility even in noisy environments. Simultaneously, it flashes a bright red light or strobe light to provide a striking visual signal to alert personnel. Installed in public places, building corridors, stairwells, and other locations, they can promptly warn people to evacuate in the early stages of a fire, buying precious time for life safety and serving as vital equipment for preventing fire accidents and reducing casualties.
[0003] Traditional fire alarms typically use LED or xenon flashlights as light sources. Due to limitations in optical design (such as lenses and reflectors) and LED chip packaging, the light cannot be emitted completely uniformly in all directions. This results in a main light-emitting direction and an effective light-emitting angle, which means that the light emitted from certain angles may not easily attract people's attention, creating alarm blind spots and failing to provide an immediate alarm effect. At the same time, the sound waves of the buzzer inside the alarm also have angular characteristics, and their propagation range is not uniformly 360 degrees omnidirectional radiation. For example, the sound waves of a circular diaphragm have the most concentrated energy in the direction perpendicular to the diaphragm surface (axial direction), while the energy gradually attenuates along the edge of the diaphragm surface (radial direction). Therefore, the sound alarm effect can also have certain blind spots. To address the above problems, a fire alarm with multi-angle high-intensity light output is proposed. Utility Model Content
[0004] To address the technical problem that existing fire alarm systems have blind spots or weak ranges when emitting alarm signals, making it difficult to provide timely and effective alarms from all angles, this invention provides a fire alarm system with multi-angle high-intensity light output.
[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:
[0006] A fire alarm with multi-angle high-intensity light output includes a mounting base with several insertion slots arranged in a circular array, the number of which is no less than three; an audible and visual alarm unit, which is inserted and installed in the insertion slots; and a rotating hoisting shaft, which is fixedly mounted on the upper surface of the mounting base; wherein the audible and visual alarm unit includes a housing, inside which two sets of symmetrically arranged high-brightness LED modules are installed, and a buzzer is arranged between the high-brightness LED modules; the slots on both sides of the insertion slots are provided with slots, and the housing is fixedly provided with corresponding locking strips on both sides.
[0007] In one possible implementation, the high-brightness LED module includes high-brightness LED beads, with a focusing cover fixedly mounted at its front end and a heat dissipation mounting base fixedly mounted at its rear end. The heat dissipation mounting base is made of several heat-conducting curved plates welded together.
[0008] In one possible implementation, overlapping strips are fixedly provided on the inner walls of both sides of the outer shell, and transparent cover plates are adhered to the overlapping strips. These cover plates are made of high-temperature resistant transparent material, and sound-permeable holes are provided on the transparent cover plates corresponding to the positions of the buzzers.
[0009] In one possible implementation, a power supply base is fixedly provided at the bottom of the housing, which is electrically connected to a high-brightness LED bead and a buzzer via a wire. A power supply contact is fixedly provided at the bottom of the plug-in slot. When the audible and visual alarm unit is fully inserted into the plug-in slot, the power supply contact is inserted into the power supply base and electrically connected to it.
[0010] In one possible implementation, the rotating hoisting shaft includes a rotating cylinder fixedly mounted on a mounting base and a fixed cylinder. The fixed cylinder is mounted on an existing structure via a mounting plate fixedly connected to its top end. A connecting disc is fixedly connected to the top end of the rotating cylinder, and a connecting cover is fixedly connected to the bottom end of the fixed cylinder. The connecting disc is disposed in the connecting cover and rotatably connected to it. Friction rings are fixedly provided on both the upper and lower end faces of the connecting disc, which slide against the connecting cover.
[0011] In one possible implementation, a cable is connected to the mounting base, one end of which is electrically connected to a power supply contact, and the other end passes through the rotating cylinder and the fixed cylinder in sequence, and finally exits from the side of the fixed cylinder.
[0012] In one possible implementation, a set of cooperating angle limiting mechanisms is installed on the mounting base and the rotating hoisting shaft. The mechanism includes a movable plate fixedly mounted on the connecting cover, and two limiting plates fixedly mounted on the mounting base, wherein the included angle between the first limiting plate and the second limiting plate is not greater than the included angle between two adjacent insertion slots.
[0013] In one possible implementation, the bottom of the insertion slot has a through outlet.
[0014] In summary, this utility model has the following beneficial technical effects:
[0015] By opening several circumferentially arrayed plug-in slots on the mounting base, users can easily select to plug in some or all of the plug-in slots according to actual usage needs. This allows the installed sound and light alarm units to face different angles as needed, ensuring that they can achieve efficient and timely alarm functions from all directions. The above-mentioned plug-in connection installation method makes the installation and removal of sound and light alarm units very simple and easy, allowing users to freely and conveniently adjust the setting position and number of sound and light alarm units, making it very convenient to use.
[0016] The audible and visual alarm unit is equipped with a high-brightness LED module and a buzzer, which work together to complete the audible and visual alarm function. The light and sound waves emitted by the two can be directed towards the audible and visual alarm unit to ensure that it can attract people's attention at the first time. In addition, a focusing cover is set in the high-brightness LED module, which can focus the light emitted by the high-brightness LED beads and output it directly forward, thereby making the light emitted by the high-brightness LED beads stronger and playing a better alarm role.

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0025] like Figure 1 - Figure 2 As shown, this embodiment provides a fire alarm with multi-angle high-intensity light output, including a mounting base 1, on which a plurality of insertion slots 11 arranged in a circumferential array are provided, and the number of insertion slots 11 is not less than three; an audible and visual alarm unit 2, which is inserted and installed in the insertion slots 11; and a rotating hoisting shaft 3, which is fixedly installed on the upper end face of the mounting base 1; wherein, the audible and visual alarm unit 2 includes a housing 21, inside which two sets of symmetrically arranged high-brightness LED modules 22 are installed, and a buzzer 23 is provided between the high-brightness LED modules 22.
[0026] Based on the above structural scheme, users can choose to insert the audible and visual alarm unit 2 into some or all of the plug-in slots 11 according to actual usage needs. This allows the installed audible and visual alarm unit 2 to face different angles as needed, ensuring efficient and timely alarm function from all directions. The above plug-in connection installation method makes the installation and removal of the audible and visual alarm unit 2 very simple and easy, allowing users to freely and conveniently adjust the setting position and number of the audible and visual alarm unit 2, making it very convenient to use. The audible and visual alarm unit 2 is equipped with a high-brightness LED module 22 and a buzzer 23, which can work together to complete the audible and visual alarm work. The light and sound waves emitted by the two can be directed towards the setting direction of the audible and visual alarm unit 2, ensuring that it can attract people's attention at the first time.
[0027] To ensure the stability of the plug-in connection installation of the audible and visual alarm unit 2, such as... Figure 1 - Figure 2As shown, slots 13 are provided on both sides of the insertion slot 11, and locking strips 211 corresponding to the locking strips 13 are fixedly provided on both sides of the outer casing 21. The locking strips 211 and the locking strips 13 can be connected to ensure that the sound and light alarm unit 2 can be stably locked in the insertion slot 11 and will not fall off. In addition, in order to facilitate the removal of the sound and light alarm unit 2 during disassembly, a through-hole outlet 14 is provided at the bottom of the insertion slot 11. During disassembly, the sound and light alarm unit 2 can be pushed upward through the outlet 14 to slide out of the insertion slot 11, thereby completing the removal of the sound and light alarm unit 2.
[0028] For the audible and visual alarm unit 2, such as Figure 3 As shown, the high-brightness LED module 22 includes high-brightness LED beads 221, with a focusing cover 222 fixedly installed at its front end and a heat dissipation mounting base 223 fixedly installed at its rear end. The heat dissipation mounting base 223 is made of several heat-conducting curved plates welded together. The focusing cover 222 can concentrate the light emitted by the high-brightness LED beads 221 and output it directly forward, thereby making the light emitted by the high-brightness LED beads 221 stronger and playing a better alarm role. In addition, since the high-brightness LED beads 221 generate relatively concentrated heat when working, the heat dissipation mounting base 223 can effectively conduct the heat generated by the high-brightness LED beads 221 during operation, avoiding heat accumulation and affecting working efficiency.
[0029] At the same time, such as Figure 2 As shown, overlapping strips 212 are fixedly installed on both inner walls of the outer casing 21. A transparent cover plate 24 is adhered to the overlapping strip 212. The cover plate 24 is made of a high-temperature resistant transparent material. The transparent cover plate 24 has a sound-transmitting hole 241 at the position corresponding to the buzzer 23. Based on the above structural scheme, the overlapping strip 212 provides the necessary structural foundation for the installation of the transparent cover plate 24, while the transparent cover plate 24 can protect the high-brightness LED beads 221 and the buzzer 23 without hindering their normal operation.
[0030] Because misalignment may occur during installation, causing the audible and visual alarm unit 2 installed on the mounting base 1 to not face a specific direction, or because the number of insertion slots 11 is limited, resulting in few selectable directions, it is necessary to adjust the angle of the mounting base 1 after installation by rotating the lifting shaft 3 to ensure that the audible and visual alarm unit 2 installed on it can better face the specified direction. Figure 4As shown, the rotating hoisting shaft 3 includes a rotating cylinder 31 fixedly mounted on the mounting base 1 and a fixed cylinder 33. The fixed cylinder 33 is mounted on the existing structure via a mounting plate 35 fixedly connected to its top end. A connecting disc 32 is fixedly connected to the top end of the rotating cylinder 31, and a connecting cover 34 is fixedly connected to the bottom end of the fixed cylinder 33. The connecting disc 32 is disposed in the connecting cover 34 and rotatably connected to it. Friction rings 36 are fixedly provided on both the upper and lower end faces of the connecting disc 32, which slide against the connecting cover 34. Based on the above structural scheme, the angle of the mounting base 1 can be adjusted by the rotational connection between the connecting disc 32 and the connecting cover 34. The friction rings 36 provided on the connecting disc 32 can provide rotational damping, thereby fixing the relative angle between the connecting disc 32 and the connecting cover 34 after the external force is removed, thus fixing the angle after adjustment.
[0031] In order to provide power to the audible and visual alarm unit 2, such as Figure 1 , Figure 2 , Figure 4 As shown, a power supply base 25 is fixedly installed at the bottom of the outer casing 21, which is electrically connected to the high-brightness LED bead 221 and the buzzer 23 via wires. A power supply contact 12 is fixedly installed at the bottom of the insertion slot 11. When the sound and light alarm unit 2 is fully inserted into the insertion slot 11, the power supply contact 12 is inserted into the power supply base 25 and electrically connected to it. In addition, a cable 5 is connected to the mounting base 1. One end of the cable is electrically connected to the power supply contact 12, and the other end passes through the rotating cylinder 31 and the fixed cylinder 33 in sequence, and finally exits from the side of the fixed cylinder 33. Based on the above structural scheme, the cable 5 introduces external power into the mounting base 1 and transmits it to the high-brightness LED bead 221 and the buzzer 23 through the electrical connection between the power supply contact 12 and the power supply base 25, thereby ensuring that the two can be powered on and work continuously.
[0032] Since cables 5 need to be routed along the rotating hoisting shaft 3, a set of angle limiting mechanisms 4 is installed on the mounting base 1 and the rotating hoisting shaft 3 to prevent damage from excessive twisting caused by excessive rotation. Figure 5 As shown, it includes a movable plate 41 fixedly mounted on the connecting cover 34, and a limiting plate 42 and a limiting plate 43 fixedly mounted on the mounting base 1. Based on the above structural scheme, the limiting plate 42 and the limiting plate 43 can limit the rotation range of the movable plate 41, that is, constrain the rotation amplitude of the rotating hoisting shaft 3 to a small range, so as to avoid the cable 5 from being damaged due to excessive twisting.
[0033] The included angle between the first limiting plate 42 and the second limiting plate 43 is not greater than the included angle between two adjacent plug slots 11. If the included angle range that the movable plate 41 can rotate is greater than the included angle between two adjacent plug slots 11, the angle can be adjusted by inserting the sound and light alarm unit 2 into the next adjacent plug slot 11. Therefore, the included angle between the first limiting plate 42 and the second limiting plate 43 is not practically meaningful when it is greater than the included angle of the plug slot 11, and it is also easy to cause the cable 5 to be over-twisted and damaged.
[0034] The working principle and usage process of this utility model:
[0035] The high-brightness LED module 22 and buzzer 23 inside the sound and light alarm unit 2 can work together to complete the sound and light alarm. The light and sound waves emitted by the two can be directed towards the sound and light alarm unit 2, ensuring that they can attract people's attention at the first time. The light-focusing cover 222 can concentrate the light emitted by the high-brightness LED beads 221 and output it directly forward, thereby making the light emitted by the high-brightness LED beads 221 stronger and playing a better alarm role.
[0036] In use, users can choose to insert the sound and light alarm unit 2 into some or all of the plug-in slots 11 according to actual needs, so that the installed sound and light alarm unit 2 can face different angles according to needs, ensuring that it can achieve efficient and timely alarm function from all directions. The above-mentioned plug-in connection installation method makes the installation and removal of the sound and light alarm unit 2 very simple and easy, and allows users to freely and conveniently adjust the setting position and number of the sound and light alarm unit 2, making it very convenient to use.
[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
