[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 andFigure 5 , an embodiment provided by the present invention: an emergency evacuation type fire elevator with high safety, including an elevator car body 1, both the front and back of the elevator car body 1 are connected with door heads 2, two sets of sliding mechanisms are arranged inside the door head 2, a fire door 3 is connected to the bottom of the sliding mechanism, a platform storage groove 20 is opened at the bottom of the elevator car body 1, an expandable evacuation platform 12 is movably connected inside the platform storage groove 20, the expandable evacuation platform 12 is L-shaped, the back wall of the platform storage groove 20 is connected with three hydraulic telescopic rods 13 and two scissor-type telescopic structures 14, the scissor-type telescopic structures 14 and the hydraulic telescopic rods 13 are arranged in a staggered manner, one end of the scissor-type telescopic structure 14 and the output end of the hydraulic telescopic rod 13 are connected to the bottom wall of the expandable evacuation platform 12, safety air bags 8 are connected to the top wall, both side inner walls of the elevator car body 1 and the inner wall of the fire door 3; The sliding mechanism includes a control motor 16 installed inside the door head 2, the output end of the control motor 16 is connected with a lead screw 17, two sets of chutes 15 are opened inside the door head 2, a guide rod 18 is connected inside the chute 15, the guide rod 18 is located in front of the lead screw 17, a sliding sleeve 19 is sleeved on the outer surfaces of the guide rod 18 and the lead screw 17, and the bottom of the sliding sleeve 19 is connected with the top of the fire door 3.

[0025] Further, control the operation of the motor 16 according to the instruction, drive the lead screw 17 to rotate, so that the sliding sleeve 19 moves along the direction of the guiding rod 18, realizing the opening and closing operation of the fire door 3. When there is a fire, the fire door 3 closes, and at the same time, the externally installed self-closing device automatically closes, and the mechanical locking hook locks to prevent the external fire from spreading into the elevator car main body 1. An expandable evacuation platform 12 is provided at the bottom of the elevator car main body 1. The expandable evacuation platform 12 is located below the fire door 3 behind the elevator car main body 1. The fire door 3 in front of the elevator car main body 1 is the normal exit, meeting the daily needs of people to enter and exit the elevator. The fire door 3 behind the elevator car main body 1 is the evacuation exit. Usually, the expandable evacuation platform 12 is retracted, not occupying the space of the elevator car main body 1 and the hoistway, and will not affect the normal operation of the elevator. In case of an emergency, the expandable evacuation platform 12 can be extended from the bottom of the elevator car main body 1 through the automatic sensing device, effectively utilizing the space between the elevator hoistway and the building structure, increasing the area of the evacuation exit and the buffer space, and facilitating the rapid evacuation of people to a safe area. When the normal exit cannot be used due to disasters such as fire and earthquake, the expandable evacuation platform 12 of the evacuation exit on the back extends. The expandable evacuation platform 12 can be used as an alternative evacuation passage. The expandable evacuation platform 12 can extend to a safe area, such as the refuge space on the adjacent floor or the outdoor safe area, providing a new evacuation path for people, avoiding the danger at the fire scene, and increasing the chance of people's escape. Especially when it is necessary to cross obstacles or reach a higher evacuation exit, the expandable evacuation platform 12 can extend to the floor safe area, and people can achieve rapid evacuation through the expandable evacuation platform 12. Cooperating with the traditional evacuation passage, it increases the number of evacuation passages, improves the evacuation efficiency, reduces personnel congestion and the staying time at the fire scene. If people cannot evacuate through the evacuation passage in time, the expandable evacuation platform 12 can be used as a temporary refuge place, relatively independent of the fire scene, providing a certain protection space for people, waiting for the rescue of firefighters. Moreover, the expandable evacuation platform 12 provides a new rescue passage and operation platform for firefighters. Firefighters can use the fire truck ladder to approach the expandable evacuation platform 12 and approach the trapped people to carry out rescue operations; Install safety airbags 8 around the interior and at the top of the elevator car main body 1. When the elevator encounters emergencies such as sudden falls and collisions, the safety airbags 8 quickly pop out, forming an all-round buffer protection, reducing the risk of personnel injury, and providing more comprehensive safety protection for passengers; During normal use, the fire door 3 on the back of the elevator car main body 1 is always in a closed state. When a fire breaks out in the elevator shaft or on a floor, the elevator car main body 1 moves to the same height as the adjacent floor's refuge space. At this time, when the normal elevator exit is blocked by smoke and flames and cannot be safely passed through, the fire door 3, which is the normal exit in front of the elevator car main body 1, closes. At the same time, the externally installed self-closing device automatically closes, and the mechanical lock hook locks. At the same time, the elevator landing door also remains closed to ensure the isolation between the elevator shaft and the floor, prevent people from accidentally falling into the elevator shaft from the floor side, and also reduce the possibility of smoke and heat entering the elevator shaft in case of a fire or other situations, preventing the external fire from spreading into the elevator car main body 1. Then, the trapped people or rescue personnel press the button to trigger the opening device of the evacuation opening and open the door of the evacuation opening. When the evacuation opening is opened, the extendable evacuation platform 12 extends and unfolds from the bottom of the elevator car main body 1 through an automatic sensing device. People walk from the evacuation opening onto the extendable evacuation platform 12 and then evacuate to the safe area along the extendable evacuation platform 12. The extendable evacuation platform 12 builds a transitional path from the elevator car main body 1 to the refuge space on the adjacent floor. The trapped people walk on the extendable evacuation platform 12 and evacuate to the refuge space on the adjacent floor in sequence. The normal exit is the traditional evacuation passage, while the evacuation opening and the extendable evacuation platform 12 on the back are new paths. When the stairway in the building is blocked by smoke or fire, the extendable evacuation platform 12 becomes the second evacuation passage, providing a new escape direction for people, increasing the number of evacuation passages, and avoiding congestion caused by people concentrating on the traditional passage. The extendable evacuation platform 12 can extend to the safe area on the floor, connecting the area where the elevator is located to other safe areas that are difficult to reach or inconvenient to connect by other original evacuation passages, such as connecting to the refuge floor on the adjacent floor, the outdoor balcony, or the rooftop helicopter landing pad, etc., increasing the network density of the overall evacuation passage and providing more choices for people to evacuate. If people cannot evacuate through the extendable evacuation platform 12 in time, the extendable evacuation platform 12 provides a relatively stable standing area for people, provides a broader safe haven for the trapped people, reduces the panic and discomfort of people in the narrow car, and automatically folding railing handrails are installed on the edge of the extendable evacuation platform 12 and automatically extend after the extendable evacuation platform 12 extends to prevent people from falling when walking on the extendable evacuation platform 12. The extendable evacuation platform 12 is flexible and can extend to the required length according to different evacuation needs and building structures, connecting to other safe areas and serving as a temporary passage connecting different areas, capable of crossing certain spatial obstacles. When there is a certain distance between the elevator and the safe area and it is difficult for people to directly reach the safe area from the elevator, the extendable evacuation platform 12 extends to build a temporary passage from the elevator to the safe area for people to walk on. Embodiment

[0026] Please refer toFigure 1 , Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the present invention: an emergency evacuation type fireproof elevator with high safety. A safety tong 7 is connected to the bottom of the elevator car main body 1. Angle sensors 6 are connected to the outer walls on both sides of the elevator car main body 1. A position sensor 4 and a speed sensor 5 are connected to the top of the elevator car main body 1. The speed sensor 5 is located on one side of the position sensor 4. A top lighting lamp 10 is connected to the top wall of the elevator car main body 1. The top lighting lamp 10 is located outside the airbag 8. Two groups of monitoring cameras 11 are connected to the top wall of the elevator car main body 1. The monitoring cameras 11 are located between the top lighting lamp 10 and the airbag 8. An in-car operation panel 9 is connected to one inner wall of the elevator car main body 1. The in-car operation panel 9 is located between the two airbags 8.

[0027] Furthermore, when mechanical failures such as steel wire rope breakage and brake failure occur during the operation of the elevator car main body 1, the safety tong 7 and the speed limiter will immediately act to stop the elevator car main body 1 on the guide rail, preventing the elevator car main body 1 from falling or running at high speed and ensuring the life safety of passengers. The position sensor 4 real-time monitors the specific position of the elevator car main body 1 in the hoistway, providing accurate floor information and position data for the control system, ensuring that the elevator can accurately stop at the floor during operation and can clarify its own position in case of emergency, facilitating the execution of corresponding operations. The speed sensor 5 is used to measure the running speed of the elevator car main body 1, so that the control system can make judgments and controls according to the speed signal, ensuring that the elevator running speed is within the safe range. When the speed exceeds the set threshold, the safety protection system is triggered in time. The monitoring camera 11 is used to monitor the internal situation of the elevator car main body 1. The in-car operation panel 9 is mainly used for floor selection, emergency call and opening and closing the fire door 3, facilitating passengers to operate inside the elevator car main body 1. During emergency evacuation, the fire control center or the property monitoring room can be emergently called through the in-car operation panel 9 so that the trapped people can obtain rescue in time. Embodiment

[0028] Please refer to Figure 6 , an embodiment provided by the present invention: a system of an emergency evacuation type fireproof elevator with high safety, including a building disaster detection system, an alarm system, a fire and smoke prevention system and a power system. The building disaster detection system monitors whether there is an emergency in the building through a dedicated detection device. Once an emergency is detected, the alarm system issues corresponding sound and light alarm signals. The fire and smoke prevention system prevents fire and smoke from entering the elevator car main body 1 through the fire door 3 and the externally provided self-closing device and mechanical locking hook. The power system uses a double-set independent power supply module to provide continuous power for the entire elevator; The power supply module includes a main power supply and a dedicated emergency power supply.

[0029] Furthermore, dedicated detection devices are installed at multiple locations within the building to monitor whether there is a fire or earthquake in the building. When a fire or earthquake is detected, the detection devices transmit the sensed fire signal or earthquake signal to the alarm system through signal lines. After receiving the signal, the alarm system analyzes and processes the signal, confirms the occurrence of the fire, and emits an audible and visual alarm signal. At the same time, it transmits the fire information to the control system of the elevator and the fire control center within the building. After receiving the signal, the control system determines the type and severity of the disaster, and controls the fire door 3 to close, activates the self-closing device and the mechanical locking hook to prevent the smoke from spreading into the elevator car body 1, and blocks the fire through the fire door 3 to protect the passengers within the elevator car body 1, so as to subsequently control the elevator car body 1 to reach a safe floor. When the smoke concentration detected by the smoke sensor outside the elevator car body 1 exceeds the preset value, the fire and smoke prevention system conducts mechanical smoke exhaust and discharges the smoke out of the building through the smoke exhaust duct; The elevator is powered by two sets of independent power supply modules. Each power supply mode includes a main power supply and a dedicated emergency power supply. The main power supply is the daily power supply, and the dedicated emergency power supply is a diesel generator. When the main power supply fails and cannot be used normally, the dedicated emergency power supply will provide continuous power. On this basis, two sets of independent power supplies are introduced. When the main power supply fails, the other power supply is automatically switched to improve the reliability and stability of the power supply. At the same time, an automatic switching device is equipped to ensure that the switching time is extremely short and does not affect the normal operation of the elevator. Embodiment

[0030] Please refer to Figure 6 and Figure 8 As shown in [relevant figures], an embodiment provided by the present invention is a system for an emergency evacuation type fireproof elevator with high safety. The system for an emergency evacuation type fireproof elevator with high safety further includes a safety protection system, a communication and lighting system, a ventilation and air purification system, a drainage system, a control system, and a human-machine interface. The safety protection system is used to protect the safety of the elevator car body 1 and the internal personnel. The communication and lighting system includes a dedicated telephone, a top lighting lamp 10, and an evacuation indicator installed inside the elevator car body 1. The ventilation and air purification system is responsible for introducing clean air into the elevator car body 1. The drainage system timely discharges the accumulated water generated in the elevator car body 1 during fire extinguishing through a drain outlet and a drain pump. The monitoring and control system is linked with the building disaster detection system to control the operation of the fire and smoke prevention system, the power system, the safety protection system, the communication and lighting system, the ventilation and air purification system, and the drainage system. The human-machine interface includes an operation panel 9 inside the car, floor display, and voice prompt; The safety protection system includes a fall prevention protection module, a buffer protection module, a door lock protection module, a terminal limit protection module, an overload protection module, a leakage protection module, and a lightning protection module. The fall prevention protection module includes a safety clamp 7 and a speed limiter. The buffer protection includes a hoistway buffer and a safety airbag 8. The door lock protection module includes a self-closing device, a mechanical lock hook, and an electrical interlock; The ventilation and air purification system includes a ventilation opening and an air purification device.

[0031] Furthermore, the fall prevention protection module is composed of a safety clamp 7 and a speed limiter. When the elevator overspeed or falls, the speed limiter is triggered to drive the safety clamp 7 to act, stopping the elevator car body 1 on the guide rail. When the elevator car body 1 falls, the hoistway buffer absorbs the kinetic energy during the fall, reducing the impact. At the same time, the safety airbag 8 pops out to form an all-round buffer protection, reducing the risk of personnel injury and providing more comprehensive safety protection for passengers. The door lock protection module is used to prevent the fire door 3 from opening abnormally during a disaster. The terminal limit protection module is used to protect the elevator car body 1 within the normal limit range. When the elevator car body 1 exceeds the normal limit position, the power supply is cut off to stop the elevator. The overload protection module is equipped with a weighing device installed at the bottom of the elevator car body 1. When overloaded, it triggers an alarm inside the elevator car body 1. At the same time, the fire door 3 remains open and does not allow the elevator car body 1 to operate. The lightning protection module introduces the lightning current into the ground through a lightning surge protector and a grounding system to protect electrical equipment. When a disaster occurs and passengers are trapped in the elevator car body 1, the ventilation and air purification system operates to send clean air from the outside into the elevator car body 1, providing sufficient fresh air for the trapped passengers so that they can wait for rescue safely. Embodiment

[0032] Please refer to Figure 7 , an embodiment provided by the present invention: A system for an emergency evacuation type fire elevator with high safety. The control system includes a sensor module, a linkage module, a storage and processing module, and a drive control module. The sensor module provides real-time monitoring of the overall situation of the elevator car body 1 by sensors. The linkage module is used to receive the disaster signal sent by the building disaster detection system. The storage and processing module comprehensively processes and logically analyzes the received disaster signal, determines the type and severity level of the disaster, and sends corresponding control instructions to the drive control module to control the operation of the elevator; The types of disasters are divided into fire and earthquake; When the fire is in the initial stage, the fire is small and has not spread to the elevator area, the control system gives priority to ensuring the normal operation of the elevator; When the fire is large but the elevator has not been directly threatened, the control system triggers the elevator emergency descent procedure; When the elevator area is threatened by fire, the control system automatically cuts off the elevator power supply and gives a voice prompt to the passengers in the elevator car body 1 at the same time; When there is a minor earthquake and there is no obvious abnormal shaking during the elevator operation, the control system controls the elevator car body 1 to stop at the nearest floor, opens the fire door 3 and extends the expandable evacuation platform 12 to assist passengers in evacuation; During a strong earthquake, the control system triggers the safety protection system and activates the communication and lighting systems; The sensors include a position sensor 4, a speed sensor 5, an inclination sensor 6, a temperature sensor, a smoke sensor, a monitoring camera 11 and a power supply monitoring device.

[0033] Furthermore, the control system is linked with the building disaster detection system in the building, receives the disaster signal, judges the type and severity of the disaster, and makes the optimal decision for different emergencies to improve the overall safety of the elevator. At the same time, the firefighters can reach the required floor through the elevator car body 1 without being affected by the call signals of other floors; If the fire is in the initial stage, the fire is small and has not spread to the elevator area, the control system may give priority to keeping the elevator running normally, while closely monitoring the development trend of the fire and the environmental parameters around the elevator, such as smoke concentration, temperature, etc., to prepare for possible subsequent operations. When the fire signal indicates that the fire is large but the elevator has not been directly threatened, the control system will immediately trigger the elevator landing procedure, make the elevator quickly return to the first floor or the designated fire refuge floor, and keep the car door open for personnel evacuation. At the same time, it will feedback the information that the elevator has landed in place to the fire control center and wait for further instructions from the fire personnel. If it is judged that there is a high risk that the elevator area is threatened by fire, such as the smoke concentration in front of the elevator exceeds the standard or the nearby temperature rises sharply, the control system will automatically cut off the elevator power supply to prevent the fire from spreading to the elevator car body 1 through the electrical circuit. At the same time, it will give a voice prompt to tell the passengers to keep calm and wait for rescue. If the signal received shows a minor earthquake and there is no obvious abnormal shaking during the elevator operation, the control system will control the elevator to stop at the nearest floor, open the fire door 3 to let the passengers evacuate as soon as possible. After the evacuation is completed, the elevator will automatically enter the maintenance mode and wait for professional inspection before resuming operation.
