Description

Technical Field

[0001] The utility model relates to the technical field of fire monitoring, in particular to an indoor fire safety monitoring device. Background Art

[0002] The indoor fire safety monitoring device is a device that monitors and alarms indoor fires. It is mainly used in fire protection systems. By monitoring indoor smoke, it is easy to detect fires and issue early warnings, so that firefighters can extinguish fires in time and reduce the losses caused by fires.

[0003] After searching, the Chinese patent application number 201922202999.9 discloses a smoke sensor, which relates to the field of sensor technology. The utility model includes a smoke sensor body, and four ears are fixed in a circular array on the circumferential side of the upper shell of the smoke sensor body; it also includes a protective cover body installed on the four ears; the protective cover body includes a circular ring plate; a protective mesh cover is fixed on the upper end face of the circular ring plate; a plurality of cylindrical rods arranged in a circular and uniform distribution are fixed on the upper end face of the circular ring plate; a protective mesh sheet is fixed on the outer side of the plurality of cylindrical rods; four U-shaped grooves are arranged in a circular and uniform distribution on the lower surface of the circular ring plate; and screw holes are provided in the four U-shaped grooves. The utility model combines the protective cover body with the smoke sensor body and is installed flatly on the wall in combination with the wall surface, and the protective mesh cover and the protective mesh sheet provide double protection, thereby solving the problem of the existing smoke sensor being unprotected.

[0004] The above patent still has the following deficiencies: (1) Dust can easily interfere with the monitoring of the device. Since the device is placed on the ceiling of the room for a long time, dust and lint can easily enter the interior of the device. Dust enters the sensing chamber and combines with charged ions, which can easily cause the detector to falsely alarm. At the same time, the long-term accumulated dust will cover part of the surface of the sensor, causing the sensor's ability to respond to real smoke to decrease, thereby reducing its sensitivity.

[0005] (2) It is not convenient to install and replace. Since the device is directly bolted to the surface of the ceiling, when the device needs to be tested and maintained regularly, the bolts need to be removed, which is inconvenient to operate and makes it inconvenient for the staff to disassemble and maintain the device.

[0006] Therefore, an indoor fire safety monitoring device is urgently needed to solve the above problems. Utility Model Content

[0040] A loading and unloading structure 5 is arranged on the other side of the housing 1 and is used to install and fix the housing 1. A fixing plate 6 is installed on one side of the loading and unloading structure 5;

[0041] A circuit board 7 is installed inside the housing 1. A wireless transceiver module 8 is installed at the bottom of one side of the circuit board 7. A high-decibel siren 10 is installed on one side of the wireless transceiver module 8. A smoke ion sensor 11 is installed on one side of the circuit board 7. A single-chip computer 9 is arranged on one side of the smoke ion sensor 11.

[0042] like Figure 1 , Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the loading and unloading assembly includes a mounting seat 203 fixed inside the housing 1, a first magnetic ring 204 fixed inside the mounting seat 203, and a second magnetic ring 205 installed inside one side of the filter 201, the groove inside the mounting seat 203 is consistent with the shape of the filter 201, the mounting seat 203 and the housing 1 are integrated, the second magnetic ring 205 is connected to the first magnetic ring 204 by magnetic force, the second magnetic ring 205 and the first magnetic ring 204 are located on the same horizontal center line, through the filter 2 01 filters the air entering the air inlet pipe 3 to prevent dust and lint from entering the interior of the device. At the same time, starting the fan 202 can accelerate the air entering the interior of the device to prevent dust and lint from adhering to the surface of the filter 201 and hindering the circulation of air. When the device detects smoke, the fan 202 is controlled to rotate at a high speed through the single-chip microcomputer 9 to facilitate the discharge of smoke inside the shell 1 and prevent the alarm from being damaged due to long-term exposure to high-concentration smoke. The second magnetic ring 205 is driven to separate from the first magnetic ring 204 by pulling the filter 201, so that the filter 201 can be disassembled and cleaned.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the loading and unloading structure 5 includes a connecting plate 501 fixed on one side of the shell 1, a mounting groove 502 opened in the connecting plate 501, a stopper 504 fixed in the mounting groove 502, a mounting block 503 inserted in the mounting groove 502 and connected to the fixing plate 6, and a rubber pad 505 fixed on one side of the fixing plate 6. The side cross-section of the mounting block 503 is an "L"-shaped structure, and a sliding structure is formed between the mounting block 503 and the mounting groove 502. The rubber pad 505 prevents the surface of the ceiling from being worn when the bolts are installed on the fixing plate 6. The shell 1 is held to cover the mounting groove 502 on the outside of the mounting block 503, and the shell 1 is rotated to make the stopper 504 and the mounting block 503 frictionally contact, and the position between the fixing plate 6 and the connecting plate 501 is locked to install and fix the device, and the shell 1 is rotated in the opposite direction to separate the fixing plate 6 from the connecting plate 501, and the shell 1 is disassembled.

[0044] Specifically, when the indoor fire safety monitoring device is in use: the fixing plate 6 is installed in the use position by using bolts, so that the device monitors the smoke in the room. When a fire occurs and smoke is generated, the smoke enters the interior of the housing 1 through the air intake pipe 3, so that the smoke ion sensor 11 monitors the smoke ions and feeds back the data to the single-chip microcomputer 9. Then the single-chip microcomputer 9 controls the high-decibel siren 10 to sound, and sends the data to the cloud database through the wireless transceiver module 8, so as to facilitate fire warning and filter the dust in the air through the air intake pipe 3.

[0045] The air entering the air inlet pipe 3 is filtered by the filter 201 to prevent dust and lint from entering the device. At the same time, the fan 202 is started to accelerate the air entering the device to prevent dust and lint from adhering to the surface of the filter 201 and hindering the air circulation. When the device detects smoke, the fan 202 is controlled by the single chip 9 to rotate at a high speed to discharge the smoke inside the housing 1 and prevent the alarm from being damaged due to long-term exposure to high-concentration smoke. The second magnetic ring 205 is driven to separate from the first magnetic ring 204 by pulling the filter 201, so that the filter 201 can be disassembled and cleaned.

[0046] The rubber pad 505 is used to prevent the surface of the ceiling from being worn when the bolts are installed on the fixing plate 6. Hold the shell 1 and put the installation groove 502 on the outside of the installation block 503. Rotate the shell 1 to make the stopper 504 and the installation block 503 frictionally contact, lock the position between the fixing plate 6 and the connecting plate 501, install and fix the device, rotate the shell 1 in the opposite direction with force to separate the fixing plate 6 and the connecting plate 501, and disassemble the shell 1.
