Technical Field

[0001] The utility model specifically relates to the technical field of fire extinguishing systems, in particular to an intelligent fire extinguishing system. Background Art

[0002] The intelligent fire extinguishing system is an advanced fire-fighting facility with the following features:

[0003] Highly automated: Able to automatically detect fire, determine the extent of fire and quickly initiate fire extinguishing procedures.

[0005] Fast response: Greatly shorten the time from fire occurrence to the start of firefighting operations.

[0006] Interoperability: Can be linked with other fire protection systems and building management systems.

[0007] There are two types of existing fire extinguishing systems, one is ground-mounted and the other is suspended. Generally, this type of fire extinguishing system is equipped with a smoke sensor to determine whether a fire has occurred. This type of fire extinguishing system has a low level of intelligence and cannot achieve a multi-functional effect. Utility Model Content

[0008] The purpose of the utility model is to provide an intelligent fire extinguishing system to solve the technical problem that the fire extinguishing system proposed in the above background technology is equipped with a smoke sensor to determine whether a fire occurs, and the fire extinguishing system has a low intelligence level and cannot achieve a multi-functional effect.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] An intelligent fire extinguishing system, comprising a main control board, the main control board for controlling the fire extinguishing system being electrically connected to a power module;

[0011] A fire extinguishing system, which is used for extinguishing fire from the source, is electrically connected to the main control board and the power module;

[0012] The main control board is also electrically connected to the temperature sensor module, the flame alarm module and the smoke sensor module;

[0013] The fire extinguishing system comprises a main sprinkler head which is threadedly connected to a water storage block, one end of which is connected to a water pipe.

[0014] As a further technical solution of the utility model, side tubes are threadedly connected to both sides of the water storage block, the side tubes are communicated with the inner cavity of the water storage block, and an auxiliary nozzle is installed on each side tube.

[0015] As a further technical solution of the utility model, a ball joint is welded at the lower end of the water storage block, and the ball joint is movably connected to the fixed seat; a U-shaped groove is opened on the rear side of the water storage block, and the U-shaped groove is clamped on the stop block.

[0016] As a further technical solution of the utility model, the bottoms of both sides of the water storage block are movably connected with fisheye joints, and the fisheye joints are cooperatively installed on the electric push rod; the other end of the electric push rod is movably connected to the support through a rotating shaft, and the support is fixed to the fixed seat.

[0017] As a further technical solution of the utility model, the fixing seat is fixedly installed on the rotating platform; and the stopper is fixed to the fixing seat.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model, smoke sensor: is responsible for detecting the concentration change of smoke in the environment. Once a fire occurs, the smoke generated by the combustion will spread first, and the ion or photoelectric smoke sensor will quickly sense the increase of smoke particles in the air, causing the current or light signal inside the sensor to change, thereby triggering an alarm signal;

[0020] 2. The flame sensor of the utility model mainly detects infrared or ultraviolet radiation of a specific band generated by flames. When flames appear, the photoelectric element (such as an infrared receiver) in the flame sensor receives the energy radiated by the flames and generates an electrical signal. By analyzing the signal strength, it is determined whether there is a flame and an alarm is issued in time;

[0021] 3. The utility model, temperature sensor: monitors the temperature change of the environment or a specific point. For example, using a digital temperature sensor such as DS18B20, when the temperature of a local area rises sharply due to a fire and exceeds a preset threshold, the sensor converts this temperature anomaly into an electrical signal to notify the system of the fire.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 In the embodiment of the utility model, the intelligent fire extinguishing system includes a main control board 1 and a fire extinguishing system 5. The main control board 1 for controlling the fire extinguishing system is electrically connected to a power module 6; the fire extinguishing system 5 for extinguishing a fire source is electrically connected to the main control board 1 and the power module 6; the main control board 1 can also be electrically connected to a buzzer; the power for the buzzer is provided by the power module 6.

[0031] The main control board 1 is also electrically connected to the temperature sensor module 2 , the flame alarm module 3 and the smoke sensor module 4 .

[0032] The main control board 1 is a UNO-R3 mainboard, a flame sensor and a temperature sensor, which determine the possibility of fire through programmed logic. When the reading of any or a combination of sensors exceeds a preset threshold, the main control board 1 will activate a buzzer or control the fire extinguishing system 5 to act.

[0033] In this embodiment, the fire extinguishing system 5 has a main sprinkler head 55, which is threadedly connected to a water storage block 54, and one end of the water storage block 54 is connected to a water pipe 59; the two sides of the water storage block 54 are threadedly connected to side pipes 57, which are connected to the inner cavity of the water storage block 54, and each side pipe 57 is equipped with an auxiliary sprinkler head 58.

[0034] More specifically, a ball joint 53 is welded to the lower end of the water storage block 54 , and the ball joint 53 is movably connected to the fixing seat 52 ; a U-shaped groove is opened on the rear side of the water storage block 54 , and the U-shaped groove is clamped on the stopper 56 .

[0035] When extinguishing a fire, the solenoid valve on the water pipe 59 opens, water fills the cavity inside the water storage block 54, flows to the two side pipes 57, and is sprayed out through the auxiliary sprinkler 58 and the main sprinkler 55, thereby increasing the fire extinguishing range and achieving fire extinguishing at the fire source.

[0036] In this embodiment, the bottom of both sides of the water storage block 54 are movably connected with fisheye joints, and the fisheye joints are installed on the electric push rod 510; the other end of the electric push rod 510 is movably connected to the support 511 through a rotating shaft, and the support 511 is fixed to the fixed seat 52.

[0037] By adopting the above technical solution, when the push rod of the electric push rod 510 is pushed out, the ball joint 53 at the lower end of the water storage block 54 and the fixed seat 52 at the lower end rotate flexibly, so that the angle between the water storage block 54 and the fixed seat 52 is deflected, thereby achieving fire extinguishing at different angles.

[0038] In this embodiment, the fixing seat 52 is fixedly mounted on the rotating platform 51 ; and the stopper 56 is fixed to the fixing seat 52 .

[0039] By adopting the above technical solution, the rotating platform 51 can rotate, so that the auxiliary sprinkler head 58 and the main sprinkler head 55 can accurately extinguish the fire source, thereby expanding the scope of fire extinguishing of the equipment.

[0040] The working principle of the utility model is that when the smoke, flame and temperature sensors work together, they together constitute a composite fire detection system, which can monitor the occurrence of fire more comprehensively and accurately. The specific working process is as follows:

[0041] 1. Smoke sensor: responsible for detecting changes in smoke concentration in the environment. Once a fire occurs, the smoke produced by the combustion will spread first. The ion or photoelectric smoke sensor will quickly sense the increase of smoke particles in the air, causing the current or light signal inside the sensor to change, thereby triggering an alarm signal.

[0042] 2. Flame sensor: mainly detects infrared or ultraviolet radiation of a specific band generated by flames. When a flame appears, the photoelectric element (such as an infrared receiver) in the flame sensor receives the energy of the flame radiation and generates an electrical signal. By analyzing the signal strength, it is determined whether there is a flame and an alarm is issued in time.

[0043] 3. Temperature sensor: monitors temperature changes in the environment or at a specific point. For example, using a digital temperature sensor such as DS18B20, when the temperature in a local area rises sharply due to a fire and exceeds a preset threshold, the sensor converts this temperature anomaly into an electrical signal to notify the system of the fire.

[0044] The combined working principle is shown as follows:

[0045] Under normal conditions, these three sensors continuously monitor the fire indicators they are responsible for and keep the system on standby.

[0046] When a fire first breaks out, smoke sensors may be the first to respond, detecting slight changes in smoke concentration in the air and immediately sending a warning signal.

[0047] As the fire develops, the flame sensor captures the infrared or ultraviolet radiation released by the flame, confirms the location of the fire source, and enhances the credibility of the alarm.

[0048] At the same time, the temperature sensor detected a significant increase in temperature in the local area, which further verified the occurrence of the fire and helped determine the spread of the fire.

[0049] These independent alarm signals are integrated and processed by the microcontroller or other controller to comprehensively determine whether the conditions for activating the overall alarm system, executing automatic fire extinguishing measures or evacuation instructions have been met.

[0050] Ultimately, the system activates the sound and light alarms and even controls the sprinkler fire extinguishing device to achieve rapid response and effective intervention.

[0051] Through the collaborative work of multiple sensors, the system can identify fire threats more quickly and accurately, improving safety protection effectiveness.

[0052] When extinguishing a fire, when the push rod of the electric push rod 510 is pushed out, the ball joint 53 at the lower end of the water storage block 54 and the fixed seat 52 at the lower end rotate flexibly, so that the angle between the water storage block 54 and the fixed seat 52 is deflected. In addition, the rotating platform 51 can rotate, so that the fire extinguishing equipment is aimed at the fire source; the solenoid valve on the water pipe 59 is opened, and water fills the cavity inside the water storage block 54, and flows to the two side pipes 57, and is sprayed out through the auxiliary nozzle 58 and the main nozzle 55; the fire extinguishing range is increased, thereby achieving fire extinguishing of the fire source.

[0053] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
