[0022] The working principle and beneficial effects of the above technical solution are as follows: the wall 1 fixes the first window frame 2, the first window frame 2 limits the second window frame 3 through the disassembly and assembly mechanism 4, and the second window frame 3 is removed or installed from the first window frame 2 by adjusting the disassembly and assembly mechanism 4. The detection mechanism 6 detects and identifies whether a fire occurs in the house. When the detection mechanism 6 detects a fire signal (smoke / temperature abnormality), the controller synchronously triggers the sprinkler mechanism 5 to start active fire extinguishing spraying. At the same time, it can control the disassembly and assembly mechanism 4 to release the fixed state of the second window frame 3. The second window frame 3 can be quickly flipped inward and outward to form an emergency escape passage. The inward-flipped second window frame 3 can also serve as an auxiliary pedal to help people climb out. The components in the fire extinguishing window are all made of steel and have high fire resistance. While actively extinguishing the fire, it can also cool down the people and open an escape passage, thereby increasing the escape probability of the people and ensuring their safety.

[0023] Example 2 On the basis of Example 1, Figure 1-Figure 2 As shown, the disassembly and assembly mechanism 4 includes a first transmission chamber 41, multiple second transmission chambers 42, a first clamping chamber 43 and multiple second clamping chambers 44, the first transmission chamber 41 and the multiple second transmission chambers 42 are respectively arranged in the first window frame 2, the first transmission chamber 41 and the multiple second transmission chambers 42 are connected, the first clamping chamber 43 and the multiple second clamping chambers 44 are respectively corresponding to the first transmission chamber 41 and the multiple second transmission chambers 42 are arranged in the second window frame 3, the first transmission chamber 41 is respectively provided with a first locking component 45 and a second locking component 46, the first locking component 45 and the second locking component 46 are connected by a connecting component 47, and rotating columns 35 are respectively provided on both sides of the lower part of the second window frame 3, the first window frame 2 is provided with a rotating groove 21 corresponding to the rotating column 35, and the rotating column 35 is inserted in the rotating groove 21.

[0024] The working principle and beneficial effects of the above technical solution are as follows: the first transmission cavity 41 and the second transmission cavity 42 form a three-dimensional linkage network, the first locking assembly 45 drives the second locking assembly to move through the connecting assembly 47, and by controlling the first locking assembly 45 to be pulled out from the first engaging cavity 43, the connecting assembly 47 drives the multiple second locking assemblies 46 to be pulled out from the multiple second engaging cavities 44, so that the first window frame 2 does not limit the second window frame 3, and the second window frame 3 is turned over under the rotation connection between the rotating column 35 and the rotating groove 21, thereby facilitating the disassembly and assembly of the second window frame 3; When the controller issues an instruction, the first locking component 45 drives the second locking component 46 to act synchronously through the connecting component 47. The rotating column 35 and the rotating groove 21 form a rotating fulcrum. After the lock is released, the second window frame 3 can be rotated around the axis to open, forming an escape passage while providing climbing assistance for climbing personnel.

[0025] Example 3 On the basis of Example 2, Figure 1 As shown, the first window sash 33 and the second window sash 34 are locked and connected to the first window 31 and the second window 32 respectively through a locking assembly, and the first window sash 33 and the second window sash 34 are respectively provided with a handle 36 for controlling the locking assembly; High-temperature resistant vacuum glass is provided in the first window sash 33 and the second window sash 34 .

[0026] The working principle and beneficial effects of the above technical solution are as follows: the locking assembly and the handle 36 are existing technical solutions, and the window airtightness is ensured by mechanical locking under normal conditions, while the manual handle 36 operation is retained as a backup control method; the vacuum layer blocks heat conduction, and the high-temperature resistant vacuum glass can withstand higher temperatures to increase the melting temperature of the glass, preventing the glass from melting prematurely and causing secondary damage to escaping personnel.

[0027] Example 4 On the basis of Example 3, Figures 1-4 As shown, the first locking assembly 45 includes a fixed column 451, which is vertically fixed in the first transmission cavity 41, and a buffer spring 452, a moving block 453 and an insert block 454 are sleeved on the fixed column 451. The bottom of the moving block 453 is fixedly provided with the insert block 454 inserted in the first clamping cavity 43, and the moving block 453 is provided with a moving column 455 on the side facing the interior of the house. The other end of the moving column 455 extends out of the first transmission cavity 41, and the multiple moving columns 455 outside the first transmission cavity 41 are fixedly connected by a connecting column 456, and a reinforcement sleeve 457 is provided on the connecting column 456. A telescopic gas rod 458 is fixedly provided on the wall 1 above the reinforcement sleeve 457, and the telescopic end of the telescopic gas rod 458 is fixedly connected to the top of the reinforcement sleeve 457.

[0028] The second locking assembly 46 includes a second fixed column 461, which is horizontally arranged in the second transmission cavity 42. A locking block 462 is rotatably provided on the second fixed column 461 and is inserted into the second transmission cavity 42 when in a horizontal state. An adjustment hole 463 is provided in the locking block 462, and the connecting assembly 47 is movably connected to the adjustment hole 463; the connecting assembly 47 includes a right-angle rod 471, which is arranged in the first transmission cavity 41, and one end of the right-angle rod 471 is fixedly connected to one side of the moving block 453. A plurality of limiting columns 472 are provided on the side of the right-angle rod 471 corresponding to the second fixed column 461, and a rotating sleeve 473 is rotatably provided on the limiting column 472, and the rotating sleeve 473 is inserted in the adjusting hole 463.

[0029] The working principle and beneficial effects of the above technical solution are as follows: the first transmission cavity 41 fixes the fixed column 1 451, and the fixed column 1 451 limits the buffer spring 452, the moving block 453 and the insert block 454. The moving block 453 and the insert block 454 can only move in the vertical direction along the fixed column 1 451. The buffer spring 452 provides a pre-tightening force to maintain normal locking. The moving block 453 fixes the moving column 455. The connecting column 456 connects the moving columns 455 in series. The fire signal triggers the retractable gas rod 458 to retract, and the connecting column 456 drives the moving block 453 to move upward to pull the insert block 454 out of the first clamping cavity 43 to release the lock of the first window frame 2 on the bottom of the second window frame 3. The second transmission chamber 42 fixes the second fixed column 461, and the second fixed column 461 limits the rotation of the locking block 462. When the first window frame 2 locks the second window frame 3, the locking block 462 is inserted into the second clamping chamber 44 when it is in a horizontal state. When the moving block 453 moves upward, it drives the right-angle rod 471 to move upward synchronously. The right-angle rod 471 drives multiple limiting columns 472 and the rotating sleeve 473 to move upward synchronously. The limiting column 472 and the locking block 462 rotate through the rotation sleeve 473 so that the locking block 462 can smoothly rotate with the second fixed column 461 as the axis and leave the second clamping chamber 44, thereby releasing the lock of the first window frame 2 on the side of the second window frame 3, so that the second window frame 3 can smoothly detach from the first window frame 2.

[0030] Example 5 On the basis of Example 4, Figure 1-Figure 2 As shown, the spray mechanism 5 includes an infusion cavity 51, and a plurality of nozzles 52 are provided on the first window frame 2 corresponding to the infusion cavity 51. The infusion cavity 51 is connected to the fire hydrant through a pressure valve.

[0031] The working principle and beneficial effects of the above technical solution are as follows: when a fire occurs, the pressure boosting valve maintains the pipeline pressure in real time, so that the fire hydrant supplies water to the infusion chamber 51 with sufficient water. After the controller opens the pressure boosting valve, the three-dimensional sprinkler network forms a water curtain barrier. The special angle design of the sprinkler head 52 covers the window and the surrounding wall 1 at the same time, cooling the escaping personnel and increasing the chance of escape.

[0032] Example 6 On the basis of Example 5, Figure 1-Figure 2 As shown, the detection mechanism 6 includes a detection box 61, which is fixedly arranged above the first window frame 2. A plurality of smoke inlet holes 62 are provided at the bottom of the detection box 61. A smoke sensor, a temperature sensor and a controller are arranged in the detection box 61. The smoke sensor and the temperature sensor are electrically connected to the controller, and the controller is electrically connected to the spray mechanism 5 and the disassembly and assembly mechanism 4.

[0033] The working principle and beneficial effects of the above technical solution are as follows: during a fire, smoke diffuses upwards, and the detection box 61 is fixedly arranged above the first window frame 2 to facilitate the detection of smoke. The smoke sensor and the temperature sensor detect the concentration and temperature of the smoke and send them to the controller. When the concentration and temperature of the smoke exceed the preset value, a fire is confirmed. The controller controls the sprinkler mechanism 5 to spray liquid, and the controller unlocks the telescopic gas rod 458. The escaping personnel come to the window and control the telescopic gas rod 458 to open the escape passage. The multi-sensor fusion algorithm comprehensively judges the fire situation and adopts the temperature change rate + smoke concentration dual parameter judgment mode to avoid false triggering such as cooking smoke.

[0034] Example 7 On the basis of Example 6, Figure 1-Figure 2 As shown, Also includes, A pressure detection module, used to measure the pressure in the infusion cavity 51 when the spray mechanism 5 is in operation; A temperature detection module is used to measure the water temperature when the spray mechanism 5 is in operation; A flow rate detection module, used to measure the water flow rate in the infusion cavity 51 when the spray mechanism 5 is in operation; A calculation module 1, for calculating a safety operation coefficient of the spray mechanism 5 based on the pressure in the infusion cavity 51 when the spray mechanism 5 is in an operating state; An alarm module, for issuing an alarm; a processing module, configured to compare the safe operation coefficient of the spray mechanism 5 obtained by the calculation module 1 with the limit safe operation coefficient of the spray mechanism 5; Control module, when the safety operation coefficient of the sprinkler mechanism 5 is less than or equal to the limit safety operation coefficient of the sprinkler mechanism 5, the fire extinguishing window at that position operates abnormally, and the control alarm module issues an alarm; when the safety operation coefficient of the sprinkler mechanism 5 is greater than the limit safety operation coefficient of the sprinkler mechanism 5, the fire extinguishing window at that position operates normally.

[0035] The working principle and beneficial effects of the above technical scheme are as follows: the pressure detection module measures the pressure in the infusion cavity 51 when the spray mechanism 5 is in operation, the temperature detection module measures the water temperature when the spray mechanism 5 is in operation, the flow rate detection module measures the water flow rate in the infusion cavity 51 when the spray mechanism 5 is in operation, the calculation module 1 calculates the safe operation coefficient of the spray mechanism 5 based on the pressure in the infusion cavity 51 when the spray mechanism 5 is in operation, the alarm module is used to issue an alarm, and the processing module compares the safe operation coefficient of the spray mechanism 5 obtained by the calculation module 1 with the limit safe operation coefficient of the spray mechanism 5; when the safe operation coefficient of the spray mechanism 5 is less than or equal to the limit safe operation coefficient of the spray mechanism 5, the fire extinguishing window at that position operates abnormally, and the control module controls the alarm module to issue an alarm. When the safe operation coefficient of the spray mechanism 5 is greater than the limit safe operation coefficient of the spray mechanism 5, the fire extinguishing window at that position operates normally.

[0036] Example 8 On the basis of Example 7, Figure 1-Figure 2 As shown, the calculation module 1 calculates based on the following formula 1: K is the safe operation coefficient of the spray mechanism 5, π is the pi, n is the number of nozzles 52, r is the nozzle radius of the nozzle 52, β is the flow coefficient, g is the acceleration of gravity, p1 is the pressure in the infusion cavity 51 when the spray mechanism 5 is in operation, p2 is the critical pressure value of water, R is the gas state, T c is the vaporization temperature of water, T b is the water temperature when the spray mechanism 5 is in operation, ρ is the density of water, ε is the recovery coefficient of the pressurizing valve, ω is the heat loss coefficient, r2 is the radius of the infusion cavity 51, v is the water flow velocity in the infusion cavity 51 when the spray mechanism 5 is in operation, and L is the length of the infusion cavity 51.

[0037] The working principle and beneficial effects of the above technical solution are: Calculate the influence coefficient of each mechanism in the fire window at this location on the safe operation state of the sprinkler mechanism 5, through Calculate the influence coefficient of temperature loss on the safe operation state of the sprinkler mechanism 5. When the safe operation coefficient of the sprinkler mechanism 5 is less than or equal to the limit safe operation coefficient of the sprinkler mechanism 5, the fire extinguishing window at that position is operating abnormally, and the control module controls the alarm module to sound an alarm to remind the escaping personnel not to escape from the fire extinguishing window at that position. When the safe operation coefficient of the sprinkler mechanism 5 is greater than the limit safe operation coefficient of the sprinkler mechanism 5, the fire extinguishing window at that position is operating normally and escape can be selected.
