Description

Technical Field

[0001] This utility model relates to the field of fire hazard monitoring technology, specifically a fire hazard monitoring and early warning device. Background Technology

[0002] The core of fire hazard monitoring involves real-time monitoring of smoke concentration and temperature changes in the environment using sensing devices such as smoke detectors and temperature detectors installed inside buildings. When the smoke concentration or temperature exceeds a set threshold, the detector will immediately send a signal. For example, ionization smoke detectors can sensitively detect tiny particles produced by combustion, while photoelectric smoke detectors react well to visible smoke. These signals are transmitted to the fire alarm controller, which will trigger an audible and visual alarm to alert people to the occurrence of a fire. At the same time, some advanced systems can also send alarm signals to relevant units such as property management centers and fire departments.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. In daily life scenarios, areas such as kitchens are prone to smoke, such as cooking fumes and water vapor. This smoke may cause smoke detectors to produce false alarms. For example, the dense smoke produced during frying and stir-frying can easily trigger the detector, causing the alarm to sound even if there is no fire hazard. A single detection component cannot accurately and promptly alert and distinguish the problem, resulting in wasted manpower for identification and elimination; 2. When it is necessary to perform regular maintenance on the fire alarm device, such as cleaning and checking the sensor performance, the existing fire alarm device is installed by screws, which makes disassembly complicated. It is necessary to unscrew each screw one by one, complete the maintenance, and then reinstall it. This increases the difficulty and time of maintenance work. In some emergency situations, such as when it is necessary to quickly check whether the device is working properly, this complicated disassembly process will delay the maintenance opportunity. Utility Model Content

[0004] The purpose of this utility model is to provide a fire hazard monitoring and early warning device to solve the problem mentioned in the background art, where existing fire early warning devices are installed using screws, making disassembly complex. This requires unscrewing each screw individually, completing maintenance, and then reinstalling, increasing the difficulty and time of maintenance. To achieve the above objective, this utility model provides the following technical solution: a fire hazard monitoring and early warning device, including a fixing plate, with a mounting plate provided behind the fixing plate;

[0005] A combustible gas detector and a temperature detector are respectively installed on one side of the fixing plate by screws. A temperature detector is located below the combustible gas detector. A first mountain-shaped buckle is installed on the other side of the fixing plate by screws. An audible and visual alarm and a fire alarm controller are respectively installed on the top of the fixing plate by screws. A fire alarm controller is located on one side of the audible and visual alarm. A smoke detector is glued to the bottom of the fixing plate. A plug plate is welded to the rear of the fixing plate.

[0006] A second mountain-shaped buckle is installed on one side of the mounting plate by screws, and a slot is installed on the front of the mounting plate by screws, with a plug inserted into the front of the slot.

[0007] Preferably, one side of the fire alarm controller is connected to four cables, and the fire alarm controller is connected to the smoke detector, combustible gas detector and temperature detector respectively through the signal bus. Flame-retardant twisted pair cables are used, and the cross-sectional area is 1.0 mm / s² and 1.5 mm / s² RVS twisted pair cables. The output ports of the fire alarm controller and the audible and visual alarm are connected to signal control lines using RVS twisted pair cables, and the power lines are all connected to a 24V DC power supply.

[0008] More preferably, the mounting plate has three second mountain-shaped buckles arranged horizontally above it, and the fixing plate has three first mountain-shaped buckles arranged horizontally above one side of it, and the first mountain-shaped buckles of the fixing plate are snapped together with the second mountain-shaped buckles of the mounting plate.

[0009] More preferably, the temperature detector consists of a thermistor probe, a thermocouple probe, a resistance temperature detector, an amplifier circuit, a filter circuit, and an analog-to-digital converter circuit.

[0010] More preferably, the insert plate has a circular slot inside, the slot has a circular slot inside, the mounting plate has slots and insert rods on both sides, and the fixing plate has insert plates on both sides.

[0011] More preferably, the external structural dimensions of the insertion rod and the insertion plate are consistent with the internal circular hole groove of the card slot.

[0012] More preferably, the external structural dimensions of the insert plate are consistent with the internal structural dimensions of the "U"-shaped groove of the card slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, multiple detectors monitor the environment from different aspects, enabling a more accurate determination of whether there are real fire hazards. When one or two of the three detectors show abnormal signals while the other detectors do not detect any abnormalities, the system will analyze and judge more carefully to avoid false alarms, thereby reducing the manpower wasted on identifying and eliminating the problem due to false alarms.

[0015] In this invention, the first and second mountain-shaped buckles are connected by a snap-fit ​​mechanism, and the insertion plate, slot, and rod work together. During maintenance, it is not necessary to unscrew each screw individually; simply pull the rod out of the insertion plate and slot to easily separate the fixing plate from the mounting plate. This greatly simplifies the disassembly process. After maintenance, the plate can be quickly reinstalled, saving time and effort. In emergency situations, such as when it is necessary to quickly check whether the device is working properly, this convenient installation and disassembly method can respond promptly without delaying maintenance due to a complex disassembly process. Maintenance personnel can quickly disassemble the device for inspection and repair, ensuring that the device can function normally at critical moments, thus improving the device's reliability and emergency response capability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a fire hazard monitoring and early warning device, including a fixing plate 1, and an mounting plate 2 is provided behind the fixing plate 1;

[0023] A combustible gas detector 102 and a temperature detector 103 are respectively installed on one side of the fixing plate 1 by screws.

[0024] A second mountain-shaped buckle 201 is installed on one side of the mounting plate 2 by screws, and a slot 202 is installed on the front of the mounting plate 2 by screws, with a plug rod 203 inserted into the front of the slot 202.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, four cables are connected to one side of the fire alarm controller 104. The fire alarm controller 104 is connected to the smoke detector 106, the combustible gas detector 102, and the temperature detector 103 via a signal bus. Flame-retardant twisted-pair cables with cross-sectional areas of 1.0 mm / s and 1.5 mm / s are used. The output ports of the fire alarm controller 104 and the audible and visual alarm 105 are connected by signal control lines using RVS twisted-pair cables. All power lines are connected to a 24V DC power supply. The fire alarm controller 104 uses flame-retardant twisted-pair cables to connect to the smoke detector 106, the combustible gas detector 102, and the temperature detector 103 to receive data signals monitored by these detectors. At the same time, the output ports of the fire alarm controller 104 and the audible and visual alarm 105 are connected by signal control lines using RVS twisted-pair cables to promptly trigger the audible and visual alarm 105 when a fire hazard is detected. All connected power lines are connected to a 24V DC power supply to ensure a stable power supply for the device.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, three second mountain-shaped buckles 201 are horizontally arranged above the mounting plate 2, and three first mountain-shaped buckles 101 are horizontally arranged above one side of the fixing plate 1. The first mountain-shaped buckle 101 of the fixing plate 1 is snapped into the second mountain-shaped buckle 201 of the mounting plate 2. The snap-fit ​​connection between the first mountain-shaped buckle 101 and the second mountain-shaped buckle 201 provides a reliable way to fix the fixing plate and the mounting plate 2. The snap-fit ​​connection method makes the installation more convenient and faster, and facilitates installation and disassembly in different places.

[0027] In this embodiment, as Figure 3 As shown, the temperature detector 103 consists of a thermistor probe, a thermocouple probe, a resistance temperature detector (RTD) probe, an amplifier circuit, a filter circuit, and an analog-to-digital converter circuit. These components work together to ensure that the temperature detector 103 can accurately monitor changes in ambient temperature.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the insert plate 107 has a circular groove inside, and the slot 202 has a circular groove inside. The mounting plate 2 has slots 202 and insert rods 203 on both sides, and the fixing plate 1 has insert plates 107 on both sides. The first mountain-shaped buckle 101 and the second mountain-shaped buckle 201 determine the installation position. The mounting plate 2 has slots 202 and insert rods 203 on both sides, and the fixing plate 1 has insert plates 107 on both sides. The insert plates 107 and slots 202 play a role in connecting and reinforcing the device during installation.

[0029] In this embodiment, as Figure 3 and Figure 4 As shown, the external structural dimensions of the insertion rod 203 and the internal circular hole of the insertion plate 107 are consistent with those of the slot 202; the consistent dimensions of the insertion rod 203, the insertion plate 107, and the internal circular hole of the slot 202 ensure that the insertion rod 203 can be smoothly inserted and play a fixing role.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the external structural dimensions of the insert plate 107 are consistent with the internal structural dimensions of the "U"-shaped groove of the card slot 202; the consistency of the dimensions of the insert plate 107 and the "U"-shaped groove of the card slot 202 further ensures that the insert plate 107 can be smoothly inserted into the card slot 202, thereby achieving accurate connection between the fixing plate 1 and the mounting plate 2.

[0031] The method of use and advantages of this utility model: The working process of this fire hazard monitoring and early warning device is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, fix the mounting plate 2 in a suitable position. Install three second mountain-shaped buckles 201 on one side of the mounting plate 2 with screws. The first mountain-shaped buckle 101 at the rear of the fixing plate 1 is inserted into the second mountain-shaped buckle 201 on the mounting plate 2. Next, insert the insert plate 107 at the rear of the fixing plate 1 into the slot 202 at the front of the mounting plate 2. Since the external structural dimensions of the insert plate 107 are consistent with the internal structural dimensions of the "U"-shaped slot of the slot 202, it can be inserted smoothly. Then, insert the rod 203 into the internal circular hole of the insert plate 107 and the slot 202. Since the external structural dimensions of the rod 203 are consistent with the internal circular hole of the insert plate 107 and the slot 202, the connection is secure.

[0033] Smoke detector 106, combustible gas detector 102, and temperature detector 103 begin real-time monitoring of smoke concentration, combustible gas concentration, and temperature changes in the environment. The detectors transmit the monitored data to the fire alarm controller 104 via a signal bus. The fire alarm controller 104 analyzes and processes the received data. When it determines that there is a fire hazard, it sends a trigger signal to the audible and visual alarm 105. Upon receiving the trigger signal, the audible and visual alarm 105 emits a bright light and a high-decibel sound to alert people in the vicinity.
