Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering and safety technology, and in particular to a smart fire smoke early warning and evacuation device. Background Technology

[0002] Fire protection engineering is a comprehensive discipline involving multiple fields such as fire science, fire protection technology, architectural design, and electrical safety. It primarily studies the occurrence and development patterns of fires, and how to prevent fires through the scientific design, construction, installation, and maintenance of fire protection facilities, and effectively control and extinguish fires when they occur, thereby protecting lives and property. Specific aspects of fire protection engineering include the design of fire protection systems, such as automatic fire alarm systems, automatic sprinkler systems, fire hydrant systems, and smoke control systems; the selection and configuration of fire protection equipment, such as fire extinguishers, fire elevators, and emergency lighting; and the construction management, quality acceptance, and maintenance of fire protection projects.

[0003] With the development and advancement of technology, fire protection engineering equipment has begun to use intelligent devices to provide early warnings of fire smoke. However, existing smoke detectors are mostly designed with fixed speaker orientation angles when they leave the factory. Therefore, in some complex building spaces, such as irregularly shaped rooms or places with many partitions or obstacles, speakers that cannot be adjusted in angle may make it difficult for certain areas to receive alarm sounds of sufficient intensity, creating sound dead zones. This may cause people in these areas to not hear the alarm in time, delaying their escape.

[0004] Therefore, we propose an intelligent fire smoke early warning and evacuation device to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A smart fire smoke early warning and evacuation device includes an installation base for smart fire smoke early warning and evacuation. A connecting base is fixedly inserted through the bottom of the installation base. Speaker slots are provided on both sides of the connecting base. A speaker mechanism is provided on the inner side of each of the two speaker slots. A loudspeaker is provided on one side of each of the two speaker mechanisms. A smoke alarm body is fixedly installed on the bottom of the connecting base.

[0007] Specifically, laser indicators are fixedly installed on the bottom and left and right sides of the smoke alarm body to guide evacuees in the event of a fire.

[0008] Specifically, the smoke alarm body has two detachable magnetic frames on its outer side, and the inner side of each magnetic frame is fixedly fitted with a barrier net to prevent mosquitoes and dust from entering the smoke alarm body.

[0009] Specifically, two magnetic blocks are fixedly installed on one side of the left magnetic frame, and two magnetic slots are opened on one side of the other magnetic frame. The two magnetic blocks are adapted to the corresponding magnetic slots, which facilitates the installation of the two magnetic frames.

[0010] Specifically, the surfaces of the two magnetic slots and the two magnetic blocks are all coated with an electromagnetic shielding layer to prevent the magnetic force from affecting the main body of the smoke alarm.

[0011] Specifically, an adjustment base is fixedly installed on one inner wall of each of the two speaker slots, and two motor slots are opened inside each of the two adjustment bases.

[0012] Specifically, the speaker mechanism includes a longitudinal servo motor, a longitudinal crank, a ball joint, a transverse servo motor, a transverse crank, a linkage rod, and a linkage metal block. The longitudinal servo motor and the transverse servo motor are fixedly installed on the inner sides of the two motor slots, respectively. A longitudinal crank is fixedly sleeved on the output shaft of the longitudinal servo motor, and a ball joint rotatably passes through one side of the longitudinal crank. A transverse crank is fixedly sleeved on the output shaft of the transverse servo motor, and a linkage rod rotatably passes through one side of the transverse crank. A linkage metal block is fixedly installed at one end of the linkage rod. A linkage groove is opened on the ball end of the ball joint, and the linkage metal block is slidably installed inside the linkage groove. One side of the speaker is fixedly connected to the other end of the ball joint, which facilitates the adjustment of the speaker through the ball joint.

[0013] Specifically, the speaker is fixedly fitted with an amplification horn on its outer side, which can improve the loudness and recognizability of the alarm sound relative to ambient noise, so that people can hear the alarm clearly even in noisy environments.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the speaker mechanism can be conveniently and quickly adjusted when installing the smoke alarm body, so that the sound can be accurately transmitted to all corners and avoid sound dead zones. In addition, the amplification horn can improve the loudness and recognizability of the alarm sound relative to the ambient noise, so that people can hear the alarm clearly in noisy environments, thus increasing the practicality of the device.

A connecting base 2 is fixedly inserted through the bottom of the installation base 1. Both sides of the connecting base 2 are provided with sound-speaking slots. A sound-speaking mechanism is provided inside the two sound-speaking slots. A speaker 17 is provided on one side of each of the two sound-speaking mechanisms. A smoke alarm body 3 is fixedly installed at the bottom of the connecting base 2.

[0022] In this embodiment, laser pointers 4 are fixedly installed on the bottom and left and right sides of the smoke alarm body 3 to guide the escape route when a fire occurs.

[0023] In this embodiment, two magnetic frames 7 are detachably installed on the outside of the smoke alarm body 3, and a barrier net 5 is fixedly installed on the inside of each of the two magnetic frames 7 to prevent mosquitoes and dust from entering the smoke alarm body 3.

[0024] In this embodiment, two magnetic blocks 6 are fixedly installed on one side of the magnetic frame 7 on the left side, and two magnetic slots are opened on one side of the magnetic frame 7 on the other side. The two magnetic blocks 6 are respectively adapted to the corresponding magnetic slots, which facilitates the installation of the two magnetic frames 7.

[0025] In this embodiment, the surfaces of the two magnetic slots and the two magnetic blocks 6 are all provided with an electromagnetic shielding coating to prevent the magnetic force from affecting the smoke alarm body 3.

[0026] In this embodiment, an adjustment base 8 is fixedly installed on the inner wall of one side of each of the two speaker slots, and two motor slots are opened inside each of the two adjustment bases 8.

[0027] In this embodiment, the speaker mechanism includes a longitudinal servo motor 9, a longitudinal crank 10, a ball joint rod 11, a transverse servo motor 13, a transverse crank 14, a linkage rod 15, and a linkage metal block 16. The longitudinal servo motor 9 and the transverse servo motor 13 are fixedly installed on the inner sides of the two motor slots, respectively. The longitudinal crank 10 is fixedly sleeved on the output shaft of the longitudinal servo motor 9. The ball joint rod 11 is rotatably passed through one side of the longitudinal crank 10. The transverse crank 14 is fixedly sleeved on the output shaft of the transverse servo motor 13. The linkage rod 15 is rotatably passed through one side of the transverse crank 14. The linkage metal block 16 is fixedly installed at one end of the linkage rod 15. A linkage groove 12 is opened on the ball end of the ball joint rod 11. The linkage metal block 16 is slidably installed inside the linkage groove 12. One side of the speaker 17 is fixedly connected to the other end of the ball joint rod 11, so as to facilitate the adjustment of the speaker 17 through the ball joint rod 11.

[0028] In this embodiment, a loudspeaker 18 is fixedly sleeved on the outside of the speaker 17, which can improve the loudness and recognizability of the alarm sound relative to the ambient noise, so that people can hear the alarm clearly in noisy environments.

[0029] Working Principle: During the installation of the smoke alarm body 3, the operator first fixes the mounting base 1 on the top of the smoke alarm body 3 to the wall or ceiling, installs the barrier net 5, and assembles the two magnetic frames 7, aligning the two magnetic blocks 6 on the left magnetic frame 7 with the two magnetic slots on the other magnetic frame 7. The barrier net 5 effectively prevents insects, dust, and other contaminants from entering the smoke alarm body 3, thus reducing its detection sensitivity. Then, the angles of the two speakers 17 are adjusted according to the installation environment. The longitudinal servo motor 9 and the transverse servo motor 13 are activated. The longitudinal servo motor 9 drives the longitudinal crank 10 to rotate around its output shaft. The rotation of the longitudinal crank 10 causes the ball joint rod 11 to rotate around its ball end. The speaker 17, fixedly mounted on the other end of the head rod 11, flips with the ball head rod 11 to complete the adjustment of the longitudinal angle. The transverse servo motor 13 starts and drives the transverse crank 14 to rotate around the output shaft of the transverse servo motor 13. The movement of the transverse crank 14 drives the linkage rod 15 to move, which in turn drives the linkage metal block 16 to move. Since the linkage metal block 16 is slidably installed in the linkage groove 12 opened on the ball head end of the ball head rod 11, the movement of the linkage metal block 16 drives the ball head rod 11 to rotate, thereby adjusting the tilt angle of the speaker 17. After adjusting the two speakers 17 to the appropriate orientation and angle, the adjustment of the speakers 17 is completed. In the event of a fire, the loudspeaker horn 18 can improve the loudness and recognizability of the alarm sound relative to the ambient noise, and the three laser indicators 4 can guide the escapers in the smoke environment, increasing the practicality of the equipment.

[0030] The technological advancements of this invention compared to existing technologies are as follows: when installing the smoke alarm body 3, the angle and orientation of the speaker 17 can be conveniently and quickly adjusted, enabling the sound to be accurately transmitted to every corner, avoiding sound dead zones. Furthermore, the amplification horn 18 can improve the loudness and recognizability of the alarm sound relative to ambient noise, allowing people to hear the alarm clearly even in noisy environments, thus increasing the practicality of the device.
