Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, an emergency rescue device for use in an elevator car includes: an equipment housing 1 located on the upper part of the elevator car, with an equipment interlayer 11 inside the equipment housing 1; an emergency power supply 2 located in the equipment interlayer 11; a control module 3 located in the equipment interlayer 11; an environmental detection mechanism 4 connected to the control module 3; a communication module 5 connected to the control module 3; a ventilation mechanism 6 located in the equipment interlayer 11; and a storage box 7 located on the top of the car, the storage box 7 having an opening and closing door 71, with a pin 72 passing through the opening and closing door 71, and the pin 72 being connected to an electromagnet 73.

[0025] Emergency power supply 2 is connected to the elevator's power supply line, which charges emergency power supply 2. When the elevator's normal power supply line is working normally, emergency power supply 2 is in a charging state, always maintaining a backup for the elevator's power supply. Emergency power supply 2 is electrically connected to all power-consuming components inside the elevator. When an emergency occurs in the elevator and the normal power supply is interrupted, it automatically switches to emergency power supply 2 for power supply. The switching method adopts existing technology.

[0026] The environmental monitoring unit 4 includes a carbon dioxide sensor 41 and a temperature sensor 42, which are connected to the control module 3. In the event of an emergency where passengers are unable to leave the elevator car, the relatively enclosed space causes the carbon dioxide concentration and temperature inside the car to rise. At this time, the carbon dioxide sensor 41 and temperature sensor 42 monitor the information inside the car in real time, facilitating the preparation of appropriate rescue equipment by rescue personnel. Both the carbon dioxide sensor 41 and temperature sensor 42 use commercially available components. The control module 3 centrally processes and transmits the information collected by the carbon dioxide sensor 41 and temperature sensor 42 to the outside world.

[0027] The communication module 5 includes a walkie-talkie 51 and a signal transmitter 52. The walkie-talkie 51 is located on the top of the elevator car, and the signal transmitter 52 is located in the equipment mezzanine 11. The equipment mezzanine 11 makes signal transmission smoother. The walkie-talkie 51 and the signal transmitter 52 are connected by a signal. Through the walkie-talkie 51, passengers trapped in the elevator can communicate with rescuers, which makes it easier for rescuers to direct the trapped passengers to perform corresponding operations and to understand the situation of the trapped passengers in real time.

[0028] like Figure 2 As shown, the ventilation mechanism 6 is used to enhance gas exchange in the elevator car. The ventilation mechanism 6 includes a fan 61 and a filter 62. The fan 61 can rotate in both directions and the speed of the fan 61 can also be adjusted. The fan 61 connects the equipment mezzanine 11 and the elevator car. The fan 61 ventilates and maintains the air quality in the elevator car, so that the trapped people are in a relatively comfortable environment. The filter 62 is located above and below the fan 61. The filter 62 is used to protect against falling objects in the elevator shaft and prevent large particles from entering the elevator car and causing injury to the trapped people.

[0029] The top of the equipment housing 1 is provided with a ventilation hole 12, which connects the equipment interlayer 11 to the outside. When the temperature or carbon dioxide level inside the car rises, the speed of the fan 61 can be increased, thereby allowing air to enter the outside through the car and the equipment interlayer 11, thus reducing the carbon dioxide concentration and the temperature inside the car.

[0030] like Figure 3 As shown, the hinged door 71 is connected to the storage box 7 via a pivot. The hinged door 71 has a through hole 711. The upper part of the pin 72 is slidably connected to the through hole 711. A steel sleeve 721 is screwed to the top of the pin 72. The diameter of the sleeve 721 is larger than the diameter of the through hole 711. By rotating the pin 72, the top of the pin 72 can be installed or separated from the sleeve 721. The sleeve 721 cannot pass through the through hole 711. A limiting piece 723 is also provided in the middle of the pin 72. The diameter of the limiting piece 723 is larger than the diameter of the through hole 711. When the position of the pin 72 is fixed, the limiting piece 723 fits against the bottom of the hinged door 71, thereby restricting the opening of the hinged door 71. A rotating handle 722 is provided at the bottom of the pin 72. In an emergency, the pin 72 can be disengaged from the sleeve 721 by rotating the rotating handle 722.

[0031] An electromagnet 73 is located on the side wall of the storage box 7, above the through hole 711. The electromagnet 73 is electrically connected to the elevator power supply and the emergency power supply 2. When energized, the electromagnet 73 is magnetically attracted to the sleeve 721, and the limit plate 723 restricts the opening of the door 71. When the elevator power is interrupted, during the time interval between the interruption of normal power and the connection of the emergency power supply 2, the electromagnet 73 loses its magnetic force, causing the sleeve 721 and the latch 72 to fall. At this point, the door 71 is no longer restricted and automatically opens. The electromagnet 73 can also be remotely de-energized, allowing rescue personnel to remotely open the storage box 7. If the electromagnet 73 fails to de-energize, the latch 72 can be disengaged from the sleeve 721 by rotating the handle 722, allowing the door 71 to be opened manually.

[0032] The storage box 7 contains emergency supplies 74, which mainly consists of disinfection supplies and binding supplies. The emergency supplies 74 is equipped with a tow rope 741, which is connected to the top of the car. When the door 71 is opened, the emergency supplies 74 will fall, and the tow rope 741 will prevent the emergency supplies 74 from falling to the bottom of the car and causing damage.

[0033] An emergency button 8 is located on the lower side wall of the car. It is conveniently located at the bottom so that injured people can press it to call for help. The emergency button 8 is electrically connected to the intercom 51. After the emergency button 8 is turned on, people can communicate with rescuers.

[0034] The control module 3 uses an STM32 series microprocessor. The control module 3 is also connected to a signal transmitting and receiving unit, thereby controlling other components and transmitting information.

[0035] The lights inside the car are also electrically connected to emergency power supply 2.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
