DETAILED DESCRIPTION

[0013] The present invention can be explained in detail by the following examples, and the purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0014] See also Figure 1-3This embodiment provides a technical solution: a smart building fire emergency escape device, including a protection box 1 and an emergency escape box 5, a smoke alarm 2 is installed on the top of the protection box 1, a power supply 7 and a PLC controller 8 are installed on the inner top of the protection box 1, a lifting mechanism 4 is installed on the inner side of the protection box 1 near the top, a bearing unit 3 is installed on the lifting part of the lifting mechanism 4, the emergency escape box 5 is placed on the bearing unit 3, and the power supply 7 and the smoke alarm 2 are electrically connected to the PLC controller 8.

[0015] The lifting mechanism 4 includes a winding wheel 41, a rotating shaft 42, a servo motor 43 and a connecting rope 44. The winding wheel 41 is rotatably connected to the protection box 1 through the rotating shaft 42. The connecting rope 44 is wound around the winding wheel 41. The servo motor 43 is installed on the side of the protection box 1. The output shaft of the servo motor 43 is fixedly connected to the end of the rotating shaft 42. The servo motor 43 is electrically connected to the PLC controller 8. It also includes a protective cover 9, which is fixed to the side of the protection box 1. The servo motor 43 is arranged on the inner side of the protective cover 9. The protective cover 9 is used to protect the servo motor 43. The carrying unit 3 includes a connecting block 32 and a bearing seat 33. The connecting block 32 is fixed to the top of the bearing seat 33. The connecting block 32 is connected and fixed to the end of the rope of the connecting rope 44. The emergency escape box 5 is placed On the supporting seat 33, the protection box 1 is installed in each floor of the building. When a fire occurs in the building, the smoke alarm 2 gives an early warning, and the information in the smoke alarm 2 is transmitted to the PLC controller 8. The PLC controller 8 analyzes and processes the information and controls the servo motor 43 to work. The output shaft of the servo motor 43 drives the winding wheel 41 to rotate through the rotating shaft 42. The connecting rope 44 on the winding wheel 41 drives the supporting seat 33 to move up and down through the connecting block 32, so that the emergency escape box 5 on the supporting seat 33 is moved out of the protection box 1 until it is moved to a position convenient for the user to take and put. The operation is simple, which saves the step of manpower required to take the emergency escape box out of the protection box 1, shortens the escape time, and ensures the life safety of the user.

[0016] The carrying unit 3 also includes a tension sensor 31, which is arranged at the connection between the connecting rope 44 and the connecting block 32. The tension sensor 31 is electrically connected to the PLC controller 8. The tension sensor 31 detects the tension between the connecting rope 44 and the connecting block 32, and transmits the detected information to the PLC controller 8. The PLC controller 8 analyzes and processes the information. When a new emergency escape box 5 is placed on the carrying seat 33, the PLC controller 8 controls the lifting mechanism 4 to drive the carrying seat 33 to return to its original position. At this time, the emergency escape box 5 on the carrying seat 33 is stored in the protective box 1.

[0017] It also includes a lighting lamp 6, which is installed on the top of the supporting base 33. The lighting lamp 6 is electrically connected to the PLC controller 8. The lighting lamp 6 performs lighting operations. When the user finds the position of the protection box 1, the emergency escape box 5 can be directly used. The lighting is convenient for the escapee to quickly find the position of the emergency escape box 5 when the light is insufficient.

[0018] The working principle of a smart building fire emergency escape device provided by the present invention is as follows: a protection box 1 is installed on each floor of a building. When a fire occurs in the building, a smoke alarm 2 gives an early warning, and the information in the smoke alarm 2 is transmitted to a PLC controller 8. The PLC controller 8 analyzes and processes the information and controls a servo motor 43 to work. The output shaft of the servo motor 43 drives a winding wheel 41 to rotate through a rotating shaft 42. The connecting rope 44 on the winding wheel 41 drives a bearing seat 33 to perform a lifting movement through a connecting block 32, so that the emergency escape box 5 on the bearing seat 33 is moved out of the protection box. The protective box 1 is moved to a position convenient for the user to take and place. At this time, the lighting lamp 6 performs lighting operation. When the user finds the position of the protective box 1, he can directly take the emergency escape box 5. The tension sensor 31 detects the tension between the connecting rope 44 and the connecting block 32, and the detected information is transmitted to the PLC controller 8. The PLC controller 8 analyzes and processes the information. When a new emergency escape box 5 is placed on the supporting seat 33, the PLC controller 8 controls the lifting mechanism 4 to drive the supporting seat 33 to return to its original position. At this time, the emergency escape box 5 on the supporting seat 33 is stored in the protective box 1.
