Description

[0001] The present invention is a solenoid valve automatic fire extinguishing system. It designs a temperature sensor and a smoke sensor in a low-voltage circuit to sense the fire situation, triggers the solenoid valve to start, and automatically extinguishes the fire through a fine-hole water outlet at the end of the fire pipe.

[0002] In the past, firefighting projects relied on sprinkler heads, whose glass tubes shattered to release firewater. These sprinkler heads were installed high on the roof, requiring a large fire to reach them. In many major fires, the flames burst directly through the windows, igniting every room in the building. This led to numerous problems with our firefighting facilities. Firstly, there was a lack of understanding of the fire's trajectory, and firefighting plans were not accurately designed. The innovation of this invention addresses all of these issues. The primary focus of fires is windows, where flames scatter in and out. Therefore, the key to preventing fires below is to provide early warning and activate the fire extinguishing system. This invention addresses both of these issues.

[0003] The solenoid valve automatic fire extinguishing system of the present invention has the following features: Feature 1: a temperature sensor and a smoke sensor are designed in the low-voltage circuit to sense the fire situation, and the alarm simultaneously triggers the solenoid valve to start automatic fire extinguishing; Feature 2: at the end of the fire-fighting pipe controlled by the solenoid valve, there are designed fine-hole water outlets of different shapes, which can spray water columns in all directions; Feature 3: the temperature sensing resistor circuit is placed in a low space indoors to sense the fire in advance and extinguish the fire in advance; Feature 4: temperature sensors are installed at indoor air inlets, windows, and walls, and long strip-type fine-hole water outlets are installed above the windows indoors, so that outside fires cannot enter and indoor fires cannot go out; Feature 5: ammunition bottles are designed on the fire-fighting water pipes to place fire-extinguishing additive polymers to help with the early stage of rapid fire extinguishing, laying the foundation for the layout of special fire scenes.

[0004] Figures and descriptions of the figures: Figure 1 This is a summary of the entire solution of the present invention, mainly introducing the overall layout design of the monitoring and starting circuits and fire protection pipes. The dotted arrows in the figure indicate the direction of water flow. Figure 1In the figure, digital symbol ① represents the solenoid valve switch, which is an important feature of the present invention and mainly controls the opening of fire-fighting water. Digital symbol ② represents a low-voltage circuit. Digital symbol ③ represents a temperature sensor. When the thermistor on the temperature sensor is heated in the fire, the solenoid valve switch will be activated. Digital symbol ④ represents a smoke sensor. The smoke sensor is generally used in warehouses where smoking is absolutely prohibited. When the smoke alarm detects a smoke alarm, the solenoid valve water switch in the circuit is activated to extinguish the fire. Digital symbol ⑤ represents the main fire water pipe. Digital symbol ⑥ represents the branch fire water pipe. Digital symbol ⑦ represents a water pipe tee joint. Digital symbol ⑧ represents a 90° elbow for the water pipe. Digital symbol ⑨ represents a connecting flange. Digital symbol ⑩ represents an ammunition bottle, which is an important feature of the present invention and is used to store fire-extinguishing additive polymers in the fire water pipeline. Digital symbol Indicates fire extinguishing additive polymer, which is an important feature of the present invention. It makes simple water fire extinguishing more effective by adding polymer in the early stage of fire. Indicates the end hemispherical fine hole water outlet, which is an important feature of the present invention. Fire extinguishing water is sprayed to all directions through this fine hole outlet. Indicates a long, narrow hole water jet outlet, which is an important feature of the present invention. When in use, the water sprayed out acts like a water curtain door, mainly used in smoke passages, aisles and windows to prevent outside fires from entering, and also to prevent indoor fires from escaping. It is a jet of water. Indicates flame.

[0005] Figure 1 In the middle, the temperature sensor ③ senses the flame After burning, the solenoid valve water switch is activated. The fine-hole water jet outlet sprays water simultaneously to extinguish the fire. Figure 1 The smoke sensor ④ senses the smoke and activates the solenoid valve water switch at the same time. The fine-hole water jet outlet sprays out water at the same time to extinguish the fire.

[0006] Figure 1 The focus of the present invention is that temperature sensors can be placed in low spaces indoors, and flame detection layouts can be carried out for key firefighting in low-space areas such as flame channels, flammable material concentration areas, fire-prone areas, windows, air vents, etc., so that early fires can be discovered in advance and fire extinguishing can be achieved in advance. This is an important innovative invention of the present invention.

[0007] Before the solenoid valve is activated, there is no water in the fire-fighting pipeline from the solenoid valve to the end. When the solenoid valve is activated, fire-fighting water is ejected from the fine-hole water jet outlet to automatically extinguish the fire.

[0008] Instructions attached Figure 2This is the circuit diagram for a temperature sensor activating a solenoid valve. The most important symbols in the diagram are numeral ①, which represents the thermistor, and numeral ②, which represents the solenoid valve water switch. When in use, the thermistor needs to be covered with a foam cap to protect it from moisture. The most significant innovation of this invention is the design and installation of a thermistor circuit in a low-lying area of ​​the room. This allows for early detection of a fire, allowing the solenoid valve water switch to activate and extinguish the fire immediately. The circuit for a smoke sensor activating a solenoid valve works in a similar manner: detecting smoke and triggering the solenoid valve switch simultaneously enables automatic fire extinguishing.

[0009] Instructions attached Figure 3 This is a diagram of factory warehouse shelves. Numerous flammable items are placed on the shelves, so our fire protection layout design must keep pace. Thermistors installed on the shelves can immediately detect fires and initiate firefighting operations. In the diagram, symbol ① represents the high-pressure hose, symbol ② represents the hemispherical fine-hole water jet outlet, symbol ③ indicates the thermistor circuit installation location, symbol ④ indicates the indoor ceiling location, and symbol ⑤ represents the shelf. Figure 3 The present invention is innovative in that it can sense and extinguish fires in advance, and can sense fires on the shelves and extinguish them in advance.

[0010] Instructions attached Figure 4 We've seen numerous fires in hotel guest rooms, spreading from lower floors to upper floors. While fire sprinklers are installed, they lack fire protection for windows. Windows, with their curtains, serve as ventilation points and are crucial fire safety points. The present invention installs a thermistor above the window. Any fire entering or exiting this window would ignite the thermistor, automatically activating the long, narrow water jets in the room to spray water and extinguish the fire, effectively extinguishing it early. The bed is a flammable point in the room, so the present invention installs thermistors on both sides of the bed and nightstands. This provides a new solution for preventing early fires, providing precise early warning and extinguishing fires. Figure 3 The symbol ① represents a high-pressure hose, the symbol ② represents a hemispherical fine-hole water jet outlet, the symbol ③ represents a long strip fine-hole water jet outlet, primarily used to protect windows and extinguish fires, the symbol ④ represents the interior ceiling decoration, the symbol ⑤ represents the thermistor installation location, the symbol ⑥ represents a bed, the symbol ⑦ represents a window, and the symbol ⑧ represents a curtain. Figure 4 and Figure 3 The invention also installs thermistors at low positions and multiple locations to sense fires. This is a new invention and innovation of the automatic fire extinguishing system of the invention that can give early warning of fires and extinguish fires in advance. Figure 4The long strip fine hole water jet outlet is usually set in the window and designed in the channel and flue to form a water wall. The fine holes on it can form water mist to eliminate dust and smoke, and the small hole water jet column on it can extinguish fire, which is an important innovation of the present invention.

[0011] With thermistor circuits in mind, we can pre-install thermistor circuits in furniture, office desks and chairs, and Simmons mattresses. Installing them beneath the surface can prevent fires, provide early warning, and extinguish fires. This is a fire-proof smart home, and it's an innovation of this invention.

[0012] Instructions attached Figure 5 This is a new solution for exterior wall fire protection. To prevent fires from spreading from one floor to the next, this invention has been designed. As soon as a fire breaks out outside a window in one household, fire suppression is automatically initiated outside all windows above and below, thanks to thermistors installed above each window. Firefighting is now a worry-free task. This is the key innovation of this invention. Figure 5 In the figure, the numerical symbol ① represents the outer wall of a high-rise building, the numerical symbol ② represents a room, the numerical symbol ③ represents a window, the numerical symbol ④ represents the installation position of the thermistor, the numerical symbol ⑤ represents a long strip of fine-hole water outlet, the numerical symbol ⑥ represents the fire main pipe, and the numerical symbol ⑦ represents the water spraying position. Figure 5 That is, a fire protection system is constructed on the exterior wall, so that when a house catches fire and the flames fly to the window, the outdoor fire protection mechanism is activated. This is an innovative invention of automatic fire extinguishing.

[0013] Instructions attached Figure 6 This is a 3D rendering of a firefighting system for a parking garage or building. The diagram features a "S"-shaped fine-hole water jet outlet, equipped with a thermistor and two smoke alarm activation devices. Four fire extinguishing bottles are also installed to address the unique characteristics of car fires. The fire extinguishing polymer additive in the fire extinguishing bottles helps quickly extinguish fires in the early stages. Numeral symbol ① in the diagram represents the "S"-shaped fine-hole water jet outlet, and numeral symbol ② represents the fire water inlet, for a total of four inlets. Numeral symbol ③ represents the four fire extinguishing bottles. Numeral symbol ④ represents the thermistor. Numeral symbol ⑤ represents the smoke alarm activation switch. Numeral symbol ⑥ represents the car. Numeral symbol ⑦ indicates the water spray location. Figure 6 This is a new fire extinguishing solution designed by the present invention for specific fires. This solution can also be used for fire prevention in large oil depots. Figure 6 Two fire monitoring methods are demonstrated, one is thermistor and the other is smoke alarm. The simultaneous use of the two in the fire protection system is an innovation of the present invention.

[0014] The fine hole water jet outlet of the present invention can be of any shape, as long as it is full of fine holes and can spray fire water to extinguish fire. The micro holes can spray water mist and the small holes can spray water columns.

[0015] Typically, one battery valve controls one room. For a workshop of several thousand square meters, one battery valve controls approximately 200 square meters. This innovation is the battery valve automatic fire extinguishing system, designed and laid out based on the site environment. Focusing firefighting on ignition points, air vents, and the direction of fire is crucial. This invention also provides strong fire protection.

[0016] The present invention's fire prevention layout design, placement of thermistor circuits in key areas and vents, and placement of fine-hole water jets for fire extinguishing at key fire outlets represent a novel innovation. This significantly reduces fires to a manageable level, making a significant contribution to the innovation of firefighting facilities and promising widespread and viable adoption. This invention also pioneers the design of ammunition bottles within firefighting pipes, transforming water firefighting into a new combined water and polymer firefighting solution. The present invention also utilizes thermistor circuits in low-profile locations, installing them in indoor passageways, walls, vents, and above windows. This represents a significant new firefighting solution for fire prevention and extinguishing, marking a milestone in automated firefighting.
