[0002] Nowadays, most high-rise buildings are designed with escape systems, but these systems are mostly located between floors. However, most fires originate in homes. Once a fire breaks out in a high-rise building, smoke can easily enter the stairwells, severely hindering evacuation and making evacuation difficult. High-rise buildings can be tens or even hundreds of meters tall, making it extremely difficult to fight fires from the outside. People trapped on higher floors can only wait for rescue. Due to the lack of safe space, people trapped on higher floors remain in danger and may even face serious safety accidents. Summary of the Invention

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of this utility model, and are not intended to limit the protection scope of this utility model.

[0018] Example 1: Please refer to Figure 1-3 ;

[0019] This utility model provides the following technical solution: A novel household fireproof isolation device, comprising a roller box 1 installed on the ceiling wall inside a house; the roller box 1 contains a rotatable roller 11, on which a fireproof curtain 2 is wound; the bottom end of the roller box 1 has a notch 12, through which the lower end of the fireproof curtain 2 extends out of the roller box 1; the distance between the roller box 1 and the window of the house is not less than 650mm, and a rigid tail plate 21 is fixed to the lower end of the fireproof curtain 2, with the tail plate 21 having two ends... The fireproof curtain 2 is slidably inserted into the track grooves 3 fixed on both sides of the house, so that when the fireproof curtain 2 is lowered, a sealed isolation zone is formed between the fireproof curtain 2 and the window; a handle 22 is fixed on the outer wall of the tail plate 21, so as to pull the handle 22 to lower the fireproof curtain 2; a sleeve 23 is provided on the outside of the handle 22, and a pin 24 is inserted into the sleeve 23, so that when the end of the pin 24 is inserted into the preset insertion hole 31 on the track groove 3, the bottom of the tail plate 21 is pressed against the ground of the house.

[0020] It is evident that 650mm is the space required for a person to stand, and it can certainly be expanded; for example, 1 meter can achieve the same effect. The gap between the top of the fireproof curtain 2 and the roof is sealed by the roller box 1, and its sides are sealed by the track groove 3. Its lower end rests against the ground to prevent high-temperature smoke from entering, thus forming a sealed isolation zone. This creates a safe fireproof space, effectively isolating fire sources and harmful gases, making it safer and more reliable to use. It also extends the rescue time for trapped personnel. The windows can provide oxygen to trapped personnel and serve as rescue passages, improving the survival rate of trapped personnel. This is of great significance for protecting people's lives and property.

[0021] In use, personnel first enter the isolation area, then pull handle 22 to lower the fireproof curtain 2 until the lower end of the tail plate 21 rests against the floor of the building. Next, the pin 24 is inserted into the socket 31 to lock it in place, preventing the fireproof curtain 2 from retracting and also restricting its movement on all sides, allowing it to withstand greater pressure and better blocking fire sources and harmful gases. More preferably, multiple horizontal steel bars are pre-embedded inside the fireproof curtain 2, further increasing its strength and compressive strength. Finally, personnel in the isolation area can use the windows to call for help or save themselves; at least the windows can provide oxygen to trapped personnel, prolonging the time for rescue and increasing their survival rate. Furthermore, when not in use, the fireproof curtain 2 can be rolled up and stored, not occupying indoor space, making it suitable for home or office use.

[0022] In the exemplary structure of the handle 22, a pair of support rods 25 are fixed to the side wall of the sleeve 23, and the ends of the support rods 25 are fixedly connected to the side wall of the tail plate 21; a pair of retaining rings 26 are fixed to the side wall of the pin 24, and the two retaining rings 26 are respectively located on the outer sides of both ends of the sleeve 23 to prevent the pin 24 from coming out of the sleeve 23. It can be seen that the support rods 25 are supports, and the sleeve 23 has two functions: one is the gripping part of the handle 22, and the other is the sliding support of the pin 24.

[0023] An exemplary track chute 3 structure has a groove 32 on its cross-section. The end of the tail plate 21 is inserted into the groove 32. A sealing strip 33 is fixed to the side wall of the groove 32 to seal the gap between the groove 32 and the tail plate 21. The sealing strip 33 further improves the sealing performance.

[0024] To facilitate use by the elderly and children, the roller 11 is connected to a motor, which drives the fireproof curtain 2 to descend. The motor is connected to an electrical box 4 pre-installed in the isolation area via a wire 41. The electrical box 4 contains a battery to provide power to the motor. The motor switch 42 can be fixed or remote-controlled for quicker and more convenient use. The battery provides the motor with an independent power source, independent of the building's existing electrical circuits, preventing the motor from becoming unusable due to electrical failures in the event of a fire.

[0025] Preferably, a switch 42 electrically connected to the electrical box 4 is provided on the wall within the isolation zone, for controlling the raising and lowering of the fireproof curtain 2. It can be seen that the switch 42 is located on the wiring between the battery and the motor within the electrical box 4, thus controlling the motor.

[0026] Preferably, the tail plate 21, handle 22, and pin 24 are all made of stainless steel, while the track groove 3 is made of aluminum alloy. Stainless steel is corrosion-resistant and durable, allowing for long-term operation, and also has good fire resistance. The aluminum alloy track groove 3 is easy to manufacture and offers good corrosion and fire resistance, further improving the reliability of the device.

[0027] In summary, this device can create a safe, fire-resistant space, effectively isolating fire sources and harmful gases, making it safer and more reliable to use. It also extends the rescue time for trapped personnel, and the windows can provide oxygen to trapped personnel and serve as a rescue passage, improving their survival rate. Furthermore, it is convenient to use, reliable in operation, and low in cost.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The scope of this utility model is defined by the appended claims and their equivalents.
