Description

Technical Field

[0001] The present invention relates to the technical field of elevator emergency conversion to fire rescue, and specifically to a device for converting an elevator into a dedicated fire rescue device during a fire in a high-rise building. Background Art

[0002] When a fire occurs in a high-rise building, the emergency conversion of an elevator into a fire rescue device is a device used for emergency evacuation and escape when a high-rise building suffers from natural disasters or man-made disasters. It is mainly applicable to help trapped people safely and quickly escape from the fire scene in case of emergencies such as fires in high-rise buildings;

[0003] It is difficult to ensure the stability of the equipment under the condition of power failure or high temperature in the high-rise building fire protection system. Instead, the overall failure of the fire protection command system may be caused by the interruption of the quantum communication link, resulting in the elevator being unable to accurately convert into a fire elevator, reducing the safety during the elevator conversion. At the same time, when the passengers escape in the elevator, they usually use external tools to violently open the car door, which is prone to danger during the violent opening process and increases the rescue time of the passengers. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a device for emergency conversion of elevators into fire rescue equipment in high-rise buildings. The remote command end of the fire control center issues an automatic forced landing to the first floor or the refuge floor, cuts off the non-fire power supply and locks the elevator authority. When the remote command end of the fire control center issues an instruction, a quantum key distribution terminal can be used to establish an anti-interference communication link with the remote command end of the fire control center to ensure that the control instruction transmission is zero-delayed and cannot be hijacked during a fire. The elevator emergency conversion module immediately enters the fire mode after receiving the instruction from the fire control center or manual triggering. After the elevator conversion is completed, the main power supply and the emergency power supply can be automatically switched by using a dual power redundancy module. When the elevator is converted to a fire elevator, the main power supply used by the second motor can be switched to the emergency power supply, and the battery can be used as an emergency power supply. When the elevator is converted to a fire elevator, the battery can provide power for the first motor. Starting the first motor can drive the first winding roller to rotate. Since the surface of the bridge car bracket is provided with an extra auxiliary movable roller, a rope is used to drive the movable roller to connect, and the lifting and lowering of the bridge car can be controlled according to the rotation of the first winding roller. Since the rope connecting the first winding roller and the movable roller is connected to the second winding roller, the lifting and lowering of the bridge car can be controlled according to the rotation of the first winding roller. The ropes connected to the rope wheel, the double device and the tension wheel are divided into two groups. When the second winding roller is rotating, the emergency power supply of the first motor is not started. When the second winding roller is rotating, the rope on the surface of the first winding roller can drive the first motor to rotate for winding and releasing. Therefore, when a fire occurs on the elevator floor, it can be converted into a fire elevator in time to complete the normal use of the elevator, reducing the danger of the elevator. When the elevator is converted into a fire elevator for normal lifting, the temperature gradient of the shaft can be monitored by the infrared thermal imaging module to avoid danger in the high temperature area. The emergency leveling start module is used to detect the current position of the elevator and control The module calculates the nearest stopping floor according to the sensor data, and drives the elevator to that floor through the backup power supply. The electric push rod is started to retract and drive the second bridge compartment cover to move. When the second bridge compartment cover is moving, it can swing upward with the left side of the movable plate as the center of the circle. When the electric push rod is continuously retracted, the second bridge compartment cover can swing to the top of the first bridge compartment cover so that the top of the bridge compartment can be opened. When the elevator is parked at the nearest floor, escape can be made through the top of the bridge compartment. The smoke exhaust module evacuates the smoke around the elevator to ensure the freshness of the air around the elevator, so as to ensure that passengers can leave the elevator safely.

The output end of the second motor 25 is connected with a second winding roller 24, and the second winding roller 24 is located behind the first winding roller 23. The second winding roller 24, the rope wheel 29, the double device 8 and the tensioning wheel 10 are connected by ropes. A distribution box 6 is arranged on the upper surface of the machine room 5.

[0028] Starting the second motor 25 in conjunction with the reducer can drive the second winding roller 24 to rotate. Since the second winding roller 24 is connected to the rope wheel 29, the double device 8 and the tensioning wheel 10 through the rope, the rope can be wound or unwound according to the rotation of the second winding roller 24.

When the elevator is converted into a fire elevator, the elevator is lifted to the nearest floor. Since the storage battery 4 is electrically connected with the electric push rod 17, starting the electric push rod 17 can contract to drive the second car cover 19 to move. When the second car cover 19 is moving, it can swing upward with the left side of the movable plate 14 as the center. When the electric push rod 17 continuously contracts, the second car cover 19 can swing above the first car cover 15, so that the top of the car 3 can be opened.

Through the remote command terminal of the fire control center, an automatic forced descent to the first floor or the refuge floor can be issued, the non-fire power supply can be cut off, and the elevator authority can be locked. The quantum key distribution terminal is used to establish an anti-jamming communication link with the remote command terminal of the fire control center to ensure zero delay in the transmission of control instructions during a fire and that they cannot be hijacked. After receiving the instruction from the fire control center or being manually triggered, the elevator emergency conversion module immediately enters the fire mode. At this time, the elevator automatically returns to the first floor or the designated refuge floor, stops normal passenger and cargo transportation, and becomes dedicated for firefighters. The emergency conversion response module is used to display the conversion of the elevator to ensure that the elevator is successfully converted for use as a fire elevator. The dual-power redundancy module is used to automatically switch between the main power supply and the emergency power supply to ensure that the elevator can continue to operate for ≥1 hour and integrates the function of power-off emergency leveling. When the elevator is converted for use as a fire elevator, the emergency power supply can be directly used to provide power for the elevator to ascend and descend normally.

According to the data uploaded by the fire alarm module and the smoke detection module, the automatic descent to the first floor or the refuge floor can be remotely commanded through the remote command terminal of the fire control center, cutting off the non-fire power supply and locking the elevator permissions. When the remote command terminal of the fire control center issues a command, the quantum key distribution terminal can establish an anti-jamming communication link with the remote command terminal of the fire control center to ensure zero delay in the transmission of control commands during a fire and prevent hijacking. After receiving the command from the fire control center or being manually triggered, the elevator emergency conversion module immediately enters the fire mode. At this time, the elevator automatically returns to the first floor or the designated refuge floor, stops regular passenger and cargo transportation, and becomes dedicated for firefighters. The emergency conversion response module enables the observation of the elevator conversion situation through the fire control center. After the elevator conversion is completed, the dual-power redundancy module can automatically switch the main power supply and the emergency power supply, and directly use the emergency power supply to provide power for the normal lifting of the elevator.
