Description

Technical Field

[0001] The utility model relates to the technical field, and in particular to an intelligent elevator with multiple protection detection and alarm functions. Background Art

[0002] With the advent of the digital age, high-tech products are constantly being updated. At the same time, people's demand for smart elevators is also constantly increasing. Smart elevators use the Internet of Things system to record the entire cycle of IoT elevators from manufacturing to scrapping, all key information archives, and can use big data analysis methods to count indicators such as secondary maintenance rate and maintenance cycle. They are powered by electric motors and equipped with box-shaped pods, which are used to carry people or goods in multi-story buildings. If a smart elevator fails during the ride, two-way audio and video intercoms can be conducted through the "five-party call" and "one-button alarm" in the elevator. Property and rescue agencies can comfort and understand the situation in the elevator in real time, reducing unnecessary damage to trapped people.

[0003] Based on the above, elevators are a common means of transportation for people to go up and down high floors of buildings. If someone smokes in the elevator car of a high-rise residential building and causes an open flame, in a confined space, even a short period of closure will cause a series of safety hazards, especially open flames, which may cause the elevator car to catch fire. In the fire state, thick carbon monoxide smoke will be produced. If it cannot be discharged quickly, people will choke and inhale the smoke, causing coma or even greater harm. Utility Model Content

[0035] In this embodiment, the smoke sensor 4, the smoke exhaust device 6 and the sprinkler device 8 are all electrically connected to the central control unit 3. When the smoke sensor 4 detects that the smoke concentration in the elevator car 1 reaches a certain concentration, it will trigger an alarm and transmit a signal to the central control unit 3 through an electrical connection. The central control unit 3 drives the alarm 2 to sound an alarm while driving the smoke exhaust device 6 and the sprinkler device 8 to operate.

[0036] In this embodiment, the spray device 8 includes a connecting pipe 81, an installation box 82, a spray pipe 83, an electromagnetic valve 84, a gear ring 85 and a driving gear 86. The top of the connecting pipe 81 passes through the elevator car 1 and is rotatably connected to the water tank 7 through a rotating bearing. The bottom of the connecting pipe 81 is connected to the installation box 82. The installation box 82 has a ring array of spray pipes 83 that can spray the water in the water tank 7. The connecting pipe 81 is equipped with a solenoid valve 84 that is electrically connected to the central control unit 3. The electromagnetic valve 84 can drive the water in the water tank 7 to flow out. A gear ring 85 is fixed to the outer side of the top of the connecting pipe 81. The outer gear of the gear ring 85 is meshed with a driving gear 86. The driving gear 86 is driven by a motor. When the driving gear 86 rotates, it can drive the gear ring 85 and the connecting pipe 81 to rotate together, so that the spray pipe 83 can rotate during spraying, and the elevator car 1 is sprayed over a large area.

The exhaust fan 61 is connected to the elevator car 1. The top of the exhaust fan 61 is densely covered with ventilation holes 62 that can exhaust the air inside the elevator car 1. The bottom of the exhaust fan 61 is rotated with blades 63. The blades 63 are driven by a rotating mechanism 65 located in the exhaust fan 61, and a motor 64 is connected to one side of the rotating mechanism 65.

[0038] In this embodiment, the rotating mechanism 65 includes a rotating shaft 651, a rotating ring 652, a moving bar 653, a tooth group 654, an eccentric wheel 655, a limit frame 656 and a moving frame 657. The rotating shaft 651 is provided with multiple and is connected to the fan blades 63. A rotating ring 652 is installed at one end of the rotating shaft 651.

The central control unit 3 drives the alarm 2 to sound an alarm to remind the personnel in the car and the machine room, and drives the smoke exhaust device 6 and the spray device 8 to operate. The motor 64 on the smoke exhaust device 6 drives the eccentric wheel 655 to rotate under the drive of the central control unit 3. As the eccentric wheel 655 rotates, the moving frame 657 is driven to move left and right under the limiting action of the limit frame 656, thereby driving the moving bar 653 connected to the moving frame 657 to move back and forth left and right. Through the gear meshing between the tooth group 654 installed on the moving bar 653 and the rotating ring 652, the multiple rotating shafts 651 and the fan blades 63 can be driven to swing back and forth, so that the exhaust fan 61 can absorb the smoke in a large range and discharge it to the outside of the elevator car 1 when exhausting the smoke in the elevator car 1;

[0040] At the same time, the solenoid valve 84 located on the connecting pipe 81 at the top of the car will discharge the water in the water tank 7 under the drive of the central control unit 3. The water will be sprayed out through the multiple spray pipes 83 on the installation box 82 to extinguish the flame in the elevator car 1. At the same time, the motor drives the driving gear 86 to rotate, and the driving gear 86 drives the gear ring 85 and the connecting pipe 81 to rotate, so that the spray pipe 83 can rotate during spraying, and the elevator car 1 is sprayed over a large area.
