Therefore, the application of intelligent fire protection systems in the construction industry is becoming more and more extensive.

[0003] When a fire occurs inside a building, the intelligent fire protection system can detect the fire point and extinguish the fire in the fire area through the fire extinguishing device installed near the fire point; but sometimes the fire spreads quickly, and by the time the fire extinguishing device is extinguishing the fire in the fire area, the fire has spread to other areas, resulting in untimely fire extinguishing and causing more losses. Utility Model Content

[0004] In order to reduce the speed of fire spread and improve the timeliness of fire extinguishing, the present application provides a control system for building fire protection.

[0005] The present application provides a building fire control system, which adopts the following technical solution:

[0021] The following combination Figure 1-Figure 2 This application is described in further detail.

[0022] The embodiment of the present application discloses a control system for building fire protection.

[0023] As an implementation method of intelligent control system for building fire protection, refer to Figure 1 and Figure 2 , including a controller 1, a sprinkler mechanism 2, fire detectors 3 and a positioning module 4 arranged in various areas of the building, the fire detectors 3 and the positioning module 4 are respectively connected to the controller 1. The fire detectors are used to detect various areas of the building, that is, to monitor the temperature, smoke, gas and radiation light intensity of each area in real time, and send the real-time detection data to the controller 1, and the positioning module 4 sends the real-time position to the controller 1; when a fire occurs, the controller 1 controls the sprinkler mechanism 2 to spray water to extinguish the fire in the fire area.

[0024] Specifically, Figure 2 As shown, the spray mechanism 2 includes a plurality of first spray heads 21 and a movable spray assembly 22, and the plurality of first spray heads 21 are evenly distributed in multiple rows and columns. In this embodiment, the first spray head 21 adopts a glass ball sprinkler, wherein the glass ball of the glass ball sprinkler is filled with an organic solution with a high thermal expansion coefficient. At room temperature, the outer shell of the ball can withstand a certain supporting force to ensure the sealing performance of the sprinkler; when a fire occurs, the temperature of the organic solution rises and expands until the glass body is broken, and the ball seat and the seal are washed away by the water flow after losing support, thereby starting to spray water to extinguish the fire.

[0025] The mobile sprinkler assembly 22 includes a fire water tank, a pressure pump 222, a plurality of second sprinkler heads 221, and a mobile assembly for driving the second sprinkler heads 221 to move. The second sprinkler heads 221 are arranged between two adjacent rows or columns of first sprinkler heads 21. The fire water tank is connected to the pressure pump 222 through a water pipe. A hose is arranged between the pressure pump 222 and the second sprinkler heads 221. The controller 1 is connected to the pressure pump 222 and is used to control the opening and closing of the pressure pump 222. The mobile assembly includes a guide rail 225 arranged between two adjacent rows or columns of first sprinkler heads 21, a screw rod 224 arranged on the guide rail 225, and a driving member for driving the screw rod 224 to rotate. In this embodiment, the driving member is set as a motor 223, the motor 223 is connected to the controller 1, and the motor 223 is connected to the screw rod 224. A slider 226 is arranged on the screw rod 224. The slider 226 is slidably connected to the guide rail 225. The second sprinkler heads 221 are arranged on the corresponding slider 226.

[0026] A distance sensor 227 is provided on the end surface of the slider 226 along the direction in which the guide rail 225 is provided, and the distance sensor 227 is connected to the controller 1 .

[0027] When a fire occurs, the first sprinkler head 21 in the area sprays water to extinguish the fire. At the same time, the controller 1 controls the motors 223 on both sides of the fire area to start, thereby driving the screw rod 224 to rotate. Under the guidance of the slider 226 and the guide rail 225, the screw rod 224 drives the slider 226 and the second sprinkler head 221 to move. At this time, the distance sensor 227 detects the moving distance of the slider 226 in real time. When the slider 226 moves to the fire area, the controller 1 controls the motor 223 to turn off; and controls the pressure pump 222 to start, so that the second sprinkler head 221 sprays water; the first sprinkler head 21 and the two second sprinkler heads 221 spray water on the fire area at the same time, increasing the water potential, which helps to reduce the spread of the fire, thereby improving the timeliness of fire extinguishing.

[0028] In addition, in order to further improve the timeliness of fire extinguishing, two second sprinkler heads 221 and moving components are provided between two adjacent rows or columns of the first sprinkler heads 21, which helps to reduce the moving distance of the slider 226, thereby further reducing the spread speed of the fire.

[0029] As another implementation method of intelligent control system for building fire protection, Figure 1 As shown, it also includes an alarm module 5 set in each area of ​​the building. The controller 1 is connected to the alarm module 5. When a fire occurs, the controller 1 is used to control the alarm module 5 in the fire area to sound an alarm to remind users to evacuate in time or take corresponding fire extinguishing measures.

[0030] In addition, the intelligent control system further includes a manual alarm button 6 and an emergency drive module 7. The manual alarm button 6 is connected to the controller 1. After the manual alarm button 6 is pressed, an alarm signal is output. The controller 1 controls the alarm module 5 to alarm according to the alarm signal. When the fire detector 3 fails or a fire occurs in an area where no fire detector 3 is installed, the manual alarm module 5 can timely alarm and remind nearby staff to deal with the fire.

[0031] The emergency drive module 7 is connected to the controller 1, and the emergency drive module 7 is connected to the emergency lighting and the evacuation indicator light. When a fire occurs, the controller 1 controls the emergency drive module 7 to light up the emergency lighting and the evacuation indicator light. The emergency lighting can emit bright and conspicuous light after a power outage at night or when blocked by smoke, and by lighting up the evacuation indicator light, it can point out the correct escape route for people in the fire area.

[0032] The fire detection module, positioning module and alarm module are disclosed in patents with announcement numbers CN209044822U and CN205850063U, which will not be elaborated in detail here.

[0033] The implementation principle of a building fire control system in the embodiment of the present application is:

[0034] Fire detectors are used to detect various areas of the building, and real-time detection data is sent to the controller 1. The positioning module 4 sends the real-time position to the controller 1. When a fire occurs, the first sprinkler head 21 in the fire area sprays water. At the same time, the controller 1 controls the motors 223 on both sides of the fire area to start, thereby driving the screw rod 224 to rotate. Under the guidance of the slider 226 and the guide rail 225, the screw rod 224 drives the slider 226 and the second sprinkler head 221 to move. At this time, the distance sensor 227 detects the distance moved by the slider 226 in real time. When the slider 226 moves to the fire area, the controller 1 controls the motor 223 to turn off; and controls the pressure pump 222 to start, so that the second sprinkler head 221 sprays water.

[0035] At the same time, the controller 1 controls the alarm module 5 to sound an alarm, and controls the emergency drive module 7 to light up the emergency lighting and evacuation indicator lights.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
