[0022] Reference Figures 1-4 A device for monitoring and warning the operation of an elevator car comprises a chassis 1, a monitoring device 2 and an alarm 4. The tops of the monitoring device 2 and the alarm 4 are fixedly connected to the bottom of the chassis 1. A smoke detector 3 is provided between the monitoring device 2 and the alarm 4. The smoke detector 3 is fixedly connected to the bottom of the chassis 1. A light trough 101 is provided on the outside of the bottom end of the chassis 1. A light strip 5 is fixedly connected to the inside of the light trough 101. A mounting plate 6 is provided on the top of the light strip 5. The mounting plate 6 is fixedly connected to the outside of the chassis 1. An elevator car 12 is provided on one side of the top of the mounting plate 6.

[0023] During use, when a fire occurs inside the elevator car 12, the monitoring device 2 monitors the situation inside the elevator car 12. If the staff fails to find the monitoring screen in time, the elevator car 12 is on fire and smoke appears. The rising smoke is detected by the smoke detector 3. When the smoke concentration reaches a certain standard, the alarm 4 will be triggered. The alarm 4 will emit an audible and visual alarm inside the elevator car 12 to warn the passengers inside and outside the elevator car 12. At the same time, the sound emitted by the alarm 4 is collected by the monitoring device 2 and transmitted to the monitoring room, which gives a sound warning to the staff, so that the staff can find the fire in time and extinguish the fire to avoid the spread of fire and endanger the personal safety of passengers.

[0024] In this embodiment, the top of the chassis 1 is connected to the roof of the elevator car 12, the mounting plate 6 is fixedly connected to the top of the inner wall of the elevator car 12 by bolts, and the monitoring device 2, alarm 4 and smoke detector 3 are all located at the top of the inner wall of the elevator car 12.

[0025] During use, an electromechanical box 702 is installed inside the chassis 1. The circuit connecting the electronic structure inside the electromechanical box 702 to the power supply is stored inside the storage slot 102. The staff pulls out the electromechanical box 702 to move the circuit inside the storage slot 102 outward, making it convenient for the staff to inspect the electronic structure inside the electromechanical box 702.

[0026] In this embodiment, a motor slot 7 is provided on one side of the chassis 1 , into which a motor box 702 is inserted. A plurality of pinch grooves 701 are provided at the opening of the motor slot 7 , and the pinch grooves 701 are located on both sides of the top and bottom of the motor box 702 .

[0027] During use, the staff removes the bolts on the cover plate 8 to separate the cover plate 8 from the electromechanical slot 7. The staff takes out the electromechanical box 702 by pinching the slot 701, which makes it convenient for the staff to repair and inspect the internal electronic structure of the chassis 1.

[0028] In this embodiment, a cover plate 8 is provided at the opening of the electromechanical slot 7. The cover plate 8 is fixed to the opening of the electromechanical slot 7 by bolts. The outer side of the cover plate 8 is flush with the surface of the chassis 1. A storage slot 102 is provided on the top of the chassis 1.

[0029] During use, the staff regularly performs maintenance and inspection on the electromechanical box 702 to ensure that the electromechanical box 702 can operate normally. If the electromechanical box 702 fails and needs to be replaced, the staff removes the bolts on the mounting plate 6 to separate the mounting plate 6 from the inner top of the elevator car 12, making it easier for the staff to disassemble the chassis 1.

[0030] In this embodiment, an upper cover 9 is provided on the top of the mounting plate 6, and a plurality of wire holes 10 are provided on multiple sides of the storage slot 102 and the upper cover 9. The upper cover 9 is located at the top of the storage slot 102 and is fixed to the top of the chassis 1 by bolts.

[0031] When in use, the storage slot 102 on the top of the chassis 1 is used to store reserved lines to prevent the fixed length of the lines inside the chassis 1 from affecting the disassembly and removal of the chassis 1 from the top of the elevator car 12. The line through-hole 10 inside the chassis 1 is connected to the power line to facilitate the wiring of the chassis 1. The rubber plug 11 blocks the idle line to prevent ants and insects from entering the storage slot 102 to gnaw the line and cause a short circuit that affects operation.

[0032] In this embodiment, several rubber plugs 11 are provided at the bottom of the upper cover 9. One end of the rubber plug 11 is inserted into the wire hole 10, and one side of the rubber plug 11 is fitted and connected to the inner wall of the storage groove 102. The upper cover 9, the cover plate 8 and the battery are all located inside the top of the elevator car 12.

[0033] When in use, the electromechanical box 702 provides short-term power to the monitoring device 2, smoke detector 3, alarm 4 and light strip 5, so that the early warning device and the light strip 5 can still operate normally to monitor the interior of the elevator car 12 when the elevator car 12 fails, so that the staff can further understand the situation inside the elevator car 12.

[0034] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when a fire occurs inside the elevator car 12, the monitoring device 2 monitors the situation inside the elevator car 12. If the staff fails to find the monitoring screen in time, the elevator car 12 is on fire and smoke appears. The rising smoke is detected by the smoke detector 3. When the smoke concentration reaches a certain standard, the alarm 4 will be triggered. The alarm 4 will emit an audible and visual alarm inside the elevator car 12 to warn the passengers inside and outside the elevator car 12. At the same time, the sound emitted by the alarm 4 is collected and transmitted to the monitoring room by the monitoring device 2 to warn the staff, so that the staff can find the fire in time and extinguish the fire to avoid the spread of fire and endanger the personal safety of passengers.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
