DETAILED DESCRIPTION

[0020] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The application is further described in detail.

[0021] The application embodiment discloses a small fire emergency toxic gas detection device. Referring to Figures 1-3 A small fire emergency toxic gas detection device, comprising a connecting block 1, limiting holes 2 are arranged on the left and right sides of the connecting block 1, a detection device body 3 is arranged below the connecting block 1, a cavity 4 is formed in the upper end of the detection device body 3, sliding grooves 10 are formed between the inner walls on the left and right sides of the detection device body 3, the two sliding grooves 10 are in communication with the inside of the cavity 4, and a connecting mechanism and a detection mechanism for a gas detection device are arranged in the detection device body 3.

[0022] When multiple sensors detect toxic gas, the electromagnet 13 will be powered on. After the electromagnet 13 is powered on, a relatively large repulsive force will be applied to the magnetic sliding plate 17. After being subjected to the repulsive force, the magnetic sliding plate 17 will drive the alarm lamp 8 and the buzzer 9 to move downward, so that the alarm lamp 8 and the buzzer 9 are directly exposed to the outside world. During the downward movement, when the copper wire on the magnetic sliding plate 17 contacts the conductive block 15, the alarm lamp 8 and the buzzer 9 are immediately started, and a warning signal is issued, which significantly shortens the time difference from detection to alarm.

[0023] Referring to Figures 2-3 The connecting mechanism comprises limiting rods 7 arranged horizontally in the two sliding grooves 10, the two limiting rods 7 are matched with the corresponding limiting holes 2, the opposite surfaces of the two limiting rods 7 are fixedly connected with connecting rods 12, the other ends of the two connecting rods 12 extend to the two sides of the detection device body 3 and are fixedly connected with pull plates 5, and the opposite surfaces of the two limiting rods 7 are elastically connected with the inner walls of the corresponding sliding grooves 10 through compression springs 11.

[0024] When the detection device body 3 needs to be replaced, repaired or replaced, the staff pulls the two pull plates 5 to the two sides, and the two pull plates 5 pull the two limit rods 7 out of the corresponding limit holes 2 through the corresponding connecting rods 12. At this time, the detection device body 3 can be separated from the connecting block 1 easily, which improves the work efficiency. When installation is required, the above-mentioned operation is performed in reverse, without the need for professional personnel and special tools, which greatly shortens the deployment time and improves the emergency response efficiency.

[0025] Referring to Figures 2-3 , the detection mechanism includes a sliding cavity 14 opened in the detection device body 3, and a magnetic sliding plate 17 slidably connected between the inner walls of the sliding cavity 14. A rectangular cavity is opened in the detection device body 3, and an electromagnet 13 is installed in the rectangular cavity. After the electromagnet 13 is powered on, the adjacent surfaces of the electromagnet 13 and the magnetic sliding plate 17 repel each other. The upper end of the magnetic sliding plate 17 is elastically connected to the inner top of the sliding cavity 14 through a plurality of connecting springs 16.

[0026] Referring to Figures 2-3 , the lower end of the magnetic sliding plate 17 is provided with an alarm lamp 8, and the lower end of the magnetic sliding plate 17 is provided with a buzzer 9. A copper wire is arranged on the right side of the magnetic sliding plate 17. A conductive block 15 that cooperates with the copper wire is fixedly connected to the lower end of the detection device body 3. The conductive block 15 is located directly below the copper wire. The alarm lamp 8 and the buzzer 9 are electrically connected to the conductive block 15. A gas sensor 6 is installed at the lower end of the detection device body 3. The gas sensor 6 is electrically connected to the electromagnet 13. A semi-conductive gas sensor and a thermal linearity sensor are also installed at the lower end of the detection device body 3. The semi-conductive gas sensor and the thermal linearity sensor are electrically connected to the electromagnet 13. During normal use, the connecting block 1 is first fixed at the position to be detected, which can be the surface of a wall or a ceiling.

[0027] The implementation principle of the small fire emergency toxic gas detection device is as follows: when the plurality of sensors detect toxic gas during use, the electromagnet 13 is powered on. After the electromagnet 13 is powered on, a relatively large repulsive force is applied to the magnetic sliding plate 17. After being subjected to the repulsive force, the magnetic sliding plate 17 drives the alarm lamp 8 and the buzzer 9 to move downward, so that the alarm lamp 8 and the buzzer 9 are directly exposed to the outside. During the downward movement, when the copper wire on the magnetic sliding plate 17 contacts the conductive block 15, the alarm lamp 8 and the buzzer 9 are immediately started to issue a warning signal, which significantly shortens the time difference between detection and alarm.

[0028] After the warning is completed, the electromagnet 13 is powered off, and the alarm lamp 8 and the buzzer 9 are retracted into the inside of the detection device body 3, so that the alarm lamp 8 and the buzzer 9 are in a protected state.

[0029] When the detection device body 3 needs to be replaced, repaired or replaced, the staff pulls the two pull plates 5 to the two sides, and the two pull plates 5 pull the two limit rods 7 out of the corresponding limit holes 2 through the corresponding connecting rods 12, so that the detection device body 3 and the connecting block 1 can be separated easily, the working efficiency is improved, when installation is needed, only the above-mentioned operation is reversed, no professional personnel and special tools are needed, the deployment time is greatly shortened, and the emergency response efficiency is improved.
