Description

Technical Field

[0001] The utility model relates to the technical field of gas alarms, in particular to a dual-mode alarm gas alarm. Background Art

[0002] A dual-mode alarm gas alarm is a device that can use both sound and light signals to alarm. This alarm is usually used to monitor gas concentrations in indoor or outdoor environments, such as dangerous situations such as flammable gas, toxic gas or fire. In a dual-mode alarm, when an abnormal gas concentration is detected that exceeds the set threshold, a high-volume sound alarm will be issued, and a strong light signal such as a flash will also be used to attract people's attention. This dual alarm method is designed to ensure that under different environmental conditions, people with hearing impairments or people in noisy environments can detect danger signals in time. However, after the existing gas alarm is installed outdoors, dust is easily generated outdoors, and when there is a lot of dust, it will affect the alarm sensor, resulting in false alarms, which seriously affects the stability of the device during use and brings inconvenience to users.

[0029] The output end of the driven roller 206 is provided with a dust removal mechanism 3, the interior of the dust removal mechanism 3 includes a transmission shaft 301, a fan blade 302 and a protective block 303, the transmission shaft 301 is fixedly connected to the output end of the driven roller 206, the fan blade 302 is fixedly installed on the surface of the transmission shaft 301, and the protective block 303 is fixedly installed at the end of the transmission shaft 301;

[0030] The two transmission rollers 204 are connected via a fixed shaft.

[0031] Specifically, ventilation holes 4 are provided on both sides of the box body 1 , a protection frame 5 is provided on the outer side of the ventilation hole 4 , and a dust cover 6 is provided in the inner cavity of the protection frame 5 .

[0032] Furthermore, the vent 4 can promote air circulation, so that the air inside the alarm and the surrounding environment can be effectively exchanged, which helps to eliminate harmful gases, odors or mold that may accumulate inside the equipment, and provide a cleaner working environment. The setting of the protective frame 5 and the use of the dust cover 6 can effectively block dust, particles and other potential foreign matter from entering the alarm, which can reduce the contamination or interference of impurities on sensors and other key components, and maintain the normal operation and accuracy of the alarm.

[0033] Specifically, mounting frames 7 are fixedly mounted on both sides of the top of the inner cavity of the box body 1 , and couplings 8 are provided at the ends of the mounting frames 7 , and the couplings 8 are fixedly connected to the driven roller 206 .

[0034] Furthermore, the design of the coupling 8 enables power to be transmitted between the driven roller 206 and the internal parts of the driving mechanism 2, so that when the driving mechanism 2 is started, the power can be effectively transmitted to the driven roller 206, causing it to start working and push the dust removal mechanism 3 to perform dust removal operations.

[0035] Specifically, a mounting seat 9 is fixedly mounted on the top of the box body 1 by screws, and an alarm light 10 is arranged on the top of the mounting seat 9 .

[0036] Furthermore, the warning light 10 is located on the top of the mounting base 9 and can emit bright light signals to the surroundings, which can more easily attract people's attention and warn of possible dangerous situations.

[0037] Specifically, a mounting groove 11 is provided on the front of the box body 1, a protective plate 12 is mounted on the surface of the mounting groove 11, fixing holes 13 are provided on the four sides of the surface of the protective plate 12, fixing screws 14 are threadedly installed in the inner cavity of the fixing hole 13 and extend to the outer side of the protective plate 12, a mounting plate 15 is fixedly installed on the back of the box body 1, and mounting holes 16 are provided on the four sides of the surface of the mounting plate 15.

[0038] Furthermore, through the design of the installation groove 11 and the protective plate 12, the relevant components of the alarm can be easily installed and fixed. By setting the protective plate 12, it can protect the key components inside the box 1 from the intrusion of foreign substances and mechanical damage, and extend the service life of the equipment.

[0039] Specifically, a display screen 17 is fixedly mounted on the surface of the protective plate 12 , and sound generators 18 are provided on both sides of the display screen 17 and on the surface of the protective plate 12 .

[0040] Furthermore, by installing the display screen 17 on the protective plate 12, the visibility of the alarm can be improved, making the warning information clearer and more specific. The user can easily observe the information on the display screen 17 from different angles, thereby better monitoring and judging the current gas situation in real time.

[0041] Specifically, a mounting box 19 is fixedly mounted on the bottom of the box body 1 , and a connector 20 is disposed on the bottom of the mounting box 19 .

[0042] Furthermore, the connector 20 is arranged at the bottom of the installation box 19, which can provide a power input and a communication interface for connecting the alarm to an external power supply, a data cable or other equipment for data transmission and communication, thereby ensuring the normal operation and networking operation of the alarm. By setting up the installation box 19, power cables, communication cables and other cables can be organized together to reduce clutter and risks and maintain the safety and reliability of the equipment.

[0043] When in use, select a suitable location to install the alarm to ensure that the required gas can be monitored and convenient for maintenance. After confirming the installation location, fix the box 1 and connect the connector 20 to the external power supply and communication equipment to ensure that the alarm can be powered normally and transmit and communicate data with other devices. The connector 20 can be docked with the interface at the bottom of the installation box 19, and the drive mechanism 2 is connected to the driven roller 206 through the coupling 8 to achieve the driving effect. If needed, start the drive mechanism 2 to drive the driven roller 206 to drive the dust removal mechanism 3 to perform dust removal operations, observe the information on the display screen 17 to obtain real-time data on gas concentration, alarm status and system parameters. If an alarm occurs, the display screen 17 will display the corresponding warning message, and the sounder 18 will also sound an alarm.

[0044] In summary, by driving the driven roller 206 to rotate through the driving mechanism 2, and then driving the dust removal mechanism 3 to perform dust removal operations, the warning effect of the alarm can be enhanced. The coordination of its dynamic effect and auxiliary sound signal improves the visibility and auditory effect of the alarm. The operation of the driving mechanism 2 enables the dust removal mechanism 3 to quickly and efficiently remove harmful gases, molds and other substances accumulated inside the equipment, providing a relatively clean working environment. The dust removal mechanism 3 can also prevent dust and particulate matter from entering the alarm, protecting the normal operation and accuracy of key components. At the same time, the combination of the driving mechanism 2 and the dust removal mechanism 3 also provides convenience for the maintenance and maintenance of the alarm, making it convenient for users to perform necessary cleaning, replacement of the dust cover 6 and other operations to ensure the long-term stable operation of the alarm.
