Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting, and in particular to an automatic fire extinguishing system. Background Art

[0002] The most widely used fire extinguishing system in China is the automatic sprinkler system. Due to its high fire extinguishing efficiency, low investment and maintenance costs, and environmental friendliness, it is also recognized and widely used by countries around the world. Among the installed automatic sprinkler systems, 70% are wet systems, which are the most widely used. The basic principle of passive response of sprinklers in use has not changed. The activation of the entire system depends on the heat released after the fire occurs, forcing the sprinklers to start and implement fire extinguishing.

[0003] The glass ball used in the wet system is a key component in the "automatic sprinkler fire extinguishing system" and a heat-sensitive element of the sprinkler head. The glass ball used in the system is filled with organic solutions with different expansion coefficients. After thermal expansion at different temperatures, the glass ball breaks, thereby opening the sprinkler head to automatically spray water to extinguish the fire.

[0004] The glass ball of the automatic fire extinguishing system is high in strength and reliable in operation. Glass ball sprinkler heads are widely used in high-rise buildings, hotels, shopping malls, factories, warehouses and other types of buildings, and can meet the protection requirements of various danger levels. The disadvantage is that the glass ball sprinkler heads are activated by temperature sensing. Glass ball sprinkler heads are generally arranged at the ceiling. When the hot air temperature at the ceiling reaches the activation temperature of the glass ball sprinkler heads, the fire in the building has spread. It cannot be activated in time at the early stage of the fire development, thereby preventing the spread of the fire and reducing property and personnel losses. Summary of the invention

[0034] In the description of the present invention, it should be noted that, unless otherwise specified, “plurality” means two or more than two; the terms “first”, “second”, etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] Figure 1 A schematic diagram of the structure of a sprinkler nozzle provided by an embodiment of the present invention, Figure 2 The schematic diagram of the application of the sprinkler nozzle provided by the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the present invention provides an automatic fire extinguishing system, including: a system control cabinet 2-3, a sprinkler line 2-4, a water supply network 2-2 and a sprinkler 2-1;

[0036] Multiple sprinkler lines 2-4 are evenly arranged in a preset space, and each sprinkler line 2-4 is provided with a sprinkler 2-1; the system control cabinet 2-3 is connected to the sprinkler 2-1 through the sprinkler line 2-4; and multiple sprinkler heads 2-1 are respectively connected to the water supply network 2-2. After any sprinkler head 2-1 is temperature-sensing and self-starting or current-starting, the system control cabinet 2-3 starts multiple adjacent sprinkler heads 2-1 adjacent to the sprinkler head 2-1 to extinguish the fire.

[0037] In a possible implementation, the sprinkler 2-1 includes: a sprinkler frame 1-1, a glass ball 1-2, a heating element 1-3, a connecting line 1-4 and a connecting socket 1-5. The sprinkler frame 1-1 is fixed on the sprinkler line 2-4, the glass ball 1-2 is arranged in the sprinkler frame 1-1, and the heating element 1-3 is arranged in the glass ball 1-2; the heating element 1-3 is electrically connected to the connecting socket 1-5 through the connecting line 1-4; the system control cabinet 2-3 controls the heating element 1-3 to heat the glass ball 1-2 through the current until the glass ball 1-2 breaks, and the corresponding sprinkler 2-1 sprays water.

[0038] In a possible implementation, any sprinkler head 2-1 automatically starts by sensing temperature or starts by current, including: when a fire occurs, the sprinkler head 2-1 in the center of the fire danger area automatically starts by sensing temperature through the internal temperature sensing element. Alternatively, when a fire occurs, the system control cabinet 2-3 receives an artificial signal and starts the sprinkler head in the center of the fire danger area according to the artificial signal current.

[0039] In one possible implementation, the sprinkler head 2-1 is numbered; the system control cabinet 2-3 activates multiple adjacent sprinkler heads adjacent to the sprinkler head 2-1 to extinguish the fire, including: when the glass ball 1-2 in any sprinkler head 2-1 breaks, the sprinkler head 2-1 sends an automatic signal to the system control cabinet 2-3 through the sprinkler line 2-4; the automatic signal includes the sprinkler head number; the system control cabinet 2-3 searches for multiple adjacent sprinkler heads 2-1 adjacent to the sprinkler head 2-1 according to the sprinkler head number, and controls the heating elements 1-3 of the multiple adjacent sprinkler heads 2-1 to heat the glass ball 1-2 until the glass ball 1-2 breaks, and the multiple adjacent sprinkler heads 2-1 spray water.

[0040] There are multiple ways for the system control cabinet 2-3 to search for multiple adjacent sprinkler heads 2-1 adjacent to the sprinkler head 2-1 according to the sprinkler head number.

[0041] First, the system control cabinet 2-3 determines the location information of the sprinkler head 2-1 according to the sprinkler head number; constructs a fire hazard area with the location information as the center, and determines to open multiple adjacent sprinkler heads 2-1 covered by the fire hazard area according to the regional edge algorithm.

[0042] Second, the system control cabinet 2-3 determines the location information of the sprinkler head 2-1 according to the sprinkler head number; obtains a preset distance, and searches for multiple adjacent sprinkler heads 2-1 within the preset distance from the location information.

[0043] In a third method, the system control cabinet 2-3 searches for associations according to the sprinkler head numbers to determine a plurality of adjacent sprinkler heads 2-1 associated with the sprinkler head 2-1; the associations include a plurality of mutually associated sprinkler heads 2-1.

[0044] In a possible implementation, the location information of the sprinkler head 2-1 corresponds to the plane layout diagram of the sprinkler head 2-1. The present invention performs data mapping on the plane layout diagram of the sprinkler head 2-1 to form a sprinkler head 2-1 location information database, and then maps the sprinkler head location information database to form a human-computer interaction interface, so that the human-computer interaction is consistent with the actual layout of the sprinkler head 2-1, and then constructs a regional edge algorithm through automatic or manual configuration.

[0045] When the system control cabinet 2-3 receives a signal fed back by a sprinkler head 2-1, it calculates the center of the sprinkler head 2-1 according to the position information of the sprinkler head 2-1 in the plane, constructs the fire hazard area, and uses the configuration information through the center positioning and area edge algorithm to start the relevant sprinklers to sprinkle water and extinguish the fire with the fire location as the center and the area coverage as the purpose.

[0046] After the fire is discovered manually, the sprinkler 2-1 at the fire location is manually started. The system control cabinet 2-3 calculates the fire hazard area with the sprinkler 2-1 as the center based on the position positioning information of the sprinkler 2-1 in the plane, and independently constructs the fire hazard area. The configuration information is used through the center positioning and area edge algorithm to start the adjacent sprinkler heads with the fire location as the center and the area coverage as the target to spray water and extinguish the fire.

[0047] In a possible implementation, it also includes a plurality of switches corresponding to the sprinkler heads 2-1 one by one; the system control cabinet 2-3 is connected to the switches respectively.

[0048] In a possible implementation, the present invention adopts a dual-mode starting glass ball 1-2. After the sprinkler head 2-1 is temperature-sensing started, the feedback signal is used to accurately locate the actuated sprinkler head through a water sprinkler fire extinguishing control device, and then the adjacent sprinkler heads are current-started or actively started through the water sprinkler fire extinguishing control device, so that the sprinkler heads at the fire center and the fire periphery can be started normally to spray and extinguish the fire, thereby achieving an intelligent and efficient fire extinguishing effect.

[0049] In a possible implementation, the present invention adopts a dual-mode starting glass ball 1-2. After a fire occurs and before the sprinkler head 2-1 is temperature-sensing started, the sprinkler head 2-1 at the center of the fire is manually started or current-started by accurately determining the fire location. After the sprinkler head 2-1 is actuated, the sprinkler head 2-1 adjacent to the sprinkler head 2-1 is current-started, so that the sprinkler heads 2-1 at the center of the fire and the periphery of the fire can be normally started to spray and extinguish the fire, thereby achieving an intelligent and efficient fire extinguishing effect.

[0050] In one example, after the temperature sensing element is activated, the sprinkler head 2-1 immediately activates its adjacent sprinkler head 2-1 to extinguish the fire. The system power supply heats the glass ball 1-2 through the connection socket 1-5, the connection line 1-4, and the heating element 1-3. When the glass ball 1-2 is heated to the operating temperature, the glass ball 1-2 breaks, and the system water is sprayed through the sprinkler head 2-1 to extinguish the fire. The 01-1 sprinkler head 2-1 is activated, and after activation, the system control cabinet 2-3 simultaneously activates the 01-2, 02-1, and 02-2 sprinkler heads 2-1 to extinguish the fire.

[0051] In one example, after the current is activated, sprinkler head 2-1 immediately activates its adjacent sprinklers to extinguish the fire. 01-2 sprinkler head 2-1 is activated, and after activation, the system control cabinet 2-3 simultaneously activates 01-1, 02-1, 02-2, 02-3, and 01-3 sprinkler heads 2-1 to extinguish the fire;

[0052] In one example, sprinkler head 2-1 02-2 is activated, and after activation, the system simultaneously activates sprinkler heads 2-1 01-1, 02-1, 03-1, 01-2, 03-2, 01-3, 02-3, and 03-3 to extinguish the fire.

[0053] The automatic fire extinguishing system provided by the present invention realizes the control of the spread of fire and greatly improves the fire extinguishing ability of the automatic sprinkler fire extinguishing system; it can realize early fire extinguishing and realize the transformation of the fire extinguishing automatic sprinkler fire extinguishing system from passive start to active start. It provides a more reliable guarantee for reducing the danger to life and property loss, and enables the automatic sprinkler fire extinguishing system to better serve fire fighting. The present invention is simple to install and operate, with low system investment, and can be widely used in various buildings such as high-rise buildings, hotels, shopping malls, factories, warehouses, etc., and can meet the protection requirements of various danger levels.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
