[0064] Embodiment 2: please refer to Figures 13-14 The difference between the scheme and embodiment 1 is that the top of the elevator body 1 is provided with a first alarm sensor 44, and the top of the first alarm sensor 44 is attached to the clamping plate 15. The inside of the elevator shaft 2 is provided with a second alarm sensor 45. When the clamping plate 15 is pushed by the buffer damping 12, the clamping plate 15 will be separated from the first alarm sensor 44, so that the first alarm sensor 44 sends an alarm to the inside of the elevator body 1. At the same time, the clamping plate 15 will also be impacted and attached to the second alarm sensor 45 in the elevator shaft 2 under the push of the buffer damping 12, so that the second alarm sensor 45 is impacted and alarms, so that the rescue personnel can determine the layer height interval where the elevator is located through the alarm sent by the second alarm sensor 45.

[0065] Working principle: when the elevator failure rescue device based on the internet of things intelligent elevator system is used, first, the first rescue mechanism and the second rescue mechanism are respectively installed at the top and the bottom of the elevator body 1, so that the elevator body 1 slides up and down inside the elevator shaft 2, when the first elevator cable 6 connected at the top of the elevator body 1 loosens or breaks, the elevator body 1 will fall, and the first buffer assembly will start at the same time, so that the first elevator cable 6 is disconnected from the connecting roller 8, and the connecting roller 8 is disconnected from the connecting roller 8, so that the connecting disc 9 rotates, so that the connecting disc 9 loosens the traction cable 13, so that the buffer damping 12 releases the pressure to the fixed head 14, so that the buffer damping 12 pushes the fixed head 14 and the clamping plate 15 to the outside of the elevator body 1, so that the fixed head 14 and the clamping plate 15 are clamped and fixed with the inside of the elevator shaft 2, so as to fix the top of the elevator body 1;

[0066] When the connecting roller 8 loosens, it cannot fix the connecting disc 9, so that the connecting disc 9 loosens the traction cable 13, so that the traction cable 13 rotates with the guide shaft 43, so that the traction cable 13 loosens the buffer damping 12, so that the buffer damping 12 drives the fixed head 14 and the clamping plate 15 to push outward;

[0067] When the elevator body 1 falls, the bottom of the elevator body 1 will press the buffer seat 18, so that the buffer seat 18 falls under the drive of the elevator body 1, at this time, the buffer seat 18 will also drive the fixed sleeve 19 to fall, so that the fixed sleeve 19 pulls the second elevator cable 20, and the top of the second elevator cable 20 will also drive the guide roller 21 to rotate rapidly, when the rotating speed of the guide roller 21 exceeds the threshold value (such as two revolutions per second), the centrifugal mechanism will fix the guide roller 21, so that the guide roller 21 stops rotating, and the guide roller 21 will also drive the fixed sleeve 19 and the buffer seat 18 to be fixed, so as to fix and support the bottom of the elevator body 1, so that the first rescue mechanism and the second rescue mechanism can simultaneously fix and support the top and bottom of the elevator body 1;

[0068] When the centrifugal mechanism fixes the guide roller 21, the guide roller 21 will drive the fixed shaft 23 to rotate, so that the fixed shaft 23 drives the clamping plate 25 to rotate through the connecting shaft 24, since the clamping plate 25 and the connecting shaft 24 are fixed by the shaft body, when the rotating speed of the guide roller 21 exceeds the threshold value, the clamping plate 25 will rotate with the shaft body as the center, so as to drive the spring shaft 26, so that the port outside the clamping plate 25 is fixed with the clamping groove inside the fixed clamping groove plate 22, so as to stop the rotation of the guide roller 21 and fix the second elevator cable 20;

[0069] When the elevator body 1 rises, the weight 7 will descend, so that the weight 7 pulls the rear end of the second elevator cable 20 downward, and the guide roller 21 guides the second elevator cable 20;

[0070] When the data control center 28 detects a fault in the elevator, the tension sensor 41 connected at the bottom of the first elevator cable 6 can be associated with the fault monitoring module, so that the tension sensor 41 judges the tension of the first elevator cable 6, and when the first elevator cable 6 breaks or loosens, the tension monitored by the tension sensor 41 will decrease or disappear, so that the data control center 28 senses the elevator fault, and transmits the data to the remote connection platform through the Internet of Things for reporting, and since the data control center 28 is connected with the emergency battery 29, the influence of the data control center 28 caused by the power failure of the elevator can be avoided;

[0071] When the data control center 28 detects an elevator fault, the servo motor 30 can be started, so that the servo motor 30 drives the first sprocket 31 to rotate, and the first sprocket 31 drives the second sprocket 33 to rotate through the chain 32, so that the first sprocket 31 drives the turbine fan blade 34 to rotate, so that the emergency air inlet 35 transmits external oxygen to the inside of the elevator to prevent oxygen deficiency, and at the same time, the second sprocket 33 drives the threaded shaft 36 to rotate, so that the threaded shaft 36 drives the threaded sleeve 37 to rotate, so that the threaded sleeve 37 drives the camera 38 and the alarm 39 to move, and then the elevator monitoring module in the data control center 28 is connected with the camera 38, the camera 38 is moved to shoot the personnel and damage inside the elevator body 1, and at the same time, the signal alarm module in the data control center 28 is associated with the alarm 39, so that the alarm 39 moves under the drive of the threaded sleeve 37, so as to issue an audio and magnetic alarm signal and a light alarm signal in the elevator shaft 2, so that the rescue personnel can better determine the position of the elevator.

[0072] Thus a series of work is completed, and the contents not described in detail in the specification belong to the prior art known to those skilled in the art.

[0073] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
