[0002] Smoke monitoring and alarm device is an important industrial safety equipment, mainly used to monitor smoke concentration and issue an alarm when it exceeds the preset threshold to prevent fire and reduce accident losses.
[0003] By monitoring the smoke concentration in real time and issuing an alarm when it exceeds a preset threshold, it can effectively prevent fires and reduce accident losses. During the use of the smoke monitoring alarm device, the air is sampled through a sampling device to determine whether the smoke concentration exceeds the standard. The smoke monitoring alarm device in the existing technology has a certain air sampling rate. When it is necessary to change the alarm critical point according to the actual use of the monitoring environment, the smoke monitoring alarm device needs to be replaced to continue to ensure that it can effectively alarm. In addition, under long-term use, the surface of the filter sleeve absorbs a lot of dust, which affects its monitoring effect. Therefore, we propose a smoke monitoring alarm device.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0022] The embodiment of the present application provides a flue gas monitoring alarm device, which solves the problem that the sampling air rate of the flue gas monitoring alarm device is constant. When the alarm critical point needs to be changed according to the actual use of the monitoring environment, the flue gas monitoring alarm device 1 needs to be replaced to continue to ensure that it can effectively alarm. In addition, after long-term use, the surface of the sampling tube absorbs a lot of dust, which affects its monitoring effect. The problem is achieved by adjusting the shielding sleeve 401 to slide along the connecting seat 3, and rotating the adjusting nut seat 405 so that the adjusting nut seat 405 rotates along the threaded rod 404. At this time, the adjusting nut seat 405 drives the adjusting seat 403 and the shielding sleeve 401 to move until they are adjusted to a suitable position. At this time, the shielding sleeve 401 blocks the air inlet 301 on the connecting seat 3, thereby changing the rate of air entering the filter sleeve 2, which is convenient for adjusting the monitoring critical point.
[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0024] The embodiment of the utility model discloses a smoke monitoring and alarm device.
[0025] According to the attached Figure 1-3 As shown, it includes a smoke monitoring alarm device 1, a filter sleeve 2 and a connecting seat 3. The connecting seat 3 is fixedly connected to the smoke monitoring alarm device 1. The filter sleeve 2 is installed inside the smoke monitoring alarm device 1. Air enters through the filter sleeve 2 to filter the fluff in the air. The sampling device is connected to the filter sleeve 2 to sample the air for easy monitoring. An adjustment unit 4 is provided on the connecting seat 3. A scraper 5 is slidably connected to the inner wall of the connecting seat 3.
[0026] The adjustment unit 4 includes a shielding sleeve 401, which is slidably connected to the outer wall of the connecting seat 3. The shielding sleeve 401 is slidably connected to the scraper 5. When the alarm critical point needs to be changed according to the actual usage of the monitoring environment, the shielding sleeve 401 is adjusted to slide along the connecting seat 3. At this time, the shielding sleeve 401 blocks the air inlet 301 on the connecting seat 3, thereby changing the rate of air entering the filter sleeve 2, which is convenient for adjusting the monitoring critical point.
[0027] Air inlets 301 are provided at equal intervals on the inner wall of the connecting seat 3 , and air enters the filter sleeve 2 through the air inlets 301 .
[0028] The scraper 5 is slidably connected to the air inlet 301, and the scraper 5 fits the outer wall of the filter sleeve 2. The scraper 5 scrapes off the dust on the outer wall of the filter sleeve 2, and can evenly scrape off the dust on the filter sleeve 2, avoiding the occurrence of incomplete cleaning by humans.
[0029] A fixed seat 402 is provided above the scraper 5, and the fixed seat 402 is slidably connected to the shielding sleeve 401 and the scraper 5. The shielding sleeve 401 slides on the outer wall of the fixed seat 402, so that the shielding sleeve 401 moves relative to the smoke monitoring alarm device 1 and the connecting seat 3, thereby facilitating the shielding of the air inlet 301.
[0030] A threaded rod 404 is fixedly connected to the outer wall of the fixing base 402 .
[0031] An adjustment seat 403 is slidably connected to the inner wall of the threaded rod 404, and the adjustment seat 403 is fixedly connected to the shielding sleeve 401. The adjustment seat 403 slides along the threaded rod 404, driving the shielding sleeve 401 to move, adjusting the position of the shielding sleeve 401, changing the shielding range of the air inlet 301, and then changing the rate of air entering the filter sleeve 2, which is convenient for adjusting the monitoring critical point.
[0032] An adjusting nut seat 405 is threadedly connected to the inner wall of the threaded rod 404 .
[0033] The adjusting nut seat 405 is rotatably connected to the adjusting seat 403. By rotating the adjusting nut seat 405, the adjusting nut seat 405 rotates along the threaded rod 404. At this time, the adjusting nut seat 405 drives the adjusting seat 403 and the shielding sleeve 401 to move until they are adjusted to a suitable position, and the air inlet 301 is shielded by the shielding sleeve 401.
