Description

Technical Field

[0001] The invention belongs to the technical field of emergency lighting boxes, and in particular relates to an emergency lighting box. Background Art

[0002] Emergency lighting box is an important equipment for providing lighting for buildings in emergency situations. Emergency lighting is an important safety facility for modern public buildings and industrial buildings. It is closely related to personal safety and building safety. When a fire or other disaster occurs in a building and the power supply is interrupted, emergency lighting plays an important role in personnel evacuation and fire rescue work. For example, an emergency lighting box with its own power supply proposed in patent publication number CN209876858U achieves the goal of facilitating the adjustment of the length of exposed wiring, making it safer to use and easier to clean.

[0003] In order to reduce intentional damage or misoperation and improve its visibility, the existing emergency lighting boxes are usually installed at a higher position on the wall during use. However, when a fire occurs in the corridor, the thick smoke produced by the fire contains a large amount of toxic and harmful substances. These substances rise and gather at a high place under the action of hot air. As a result, people usually bend over and lower their heads when evacuating from the corridor, and the light emitted by the emergency lighting box at a higher position will be blocked by the thick smoke gathered at a high place, thereby making it lose its lighting function, which has a negative impact on people's evacuation;

[0004] In addition, some emergency lighting boxes can be removed from the wall in an emergency so that people can use them to find their way in a dark corridor. However, when people evacuate the corridor quickly, their breathing will become rapid. If there is no wet cloth to cover their mouth and nose, they will inhale a large amount of harmful gas in a short period of time and faint, which seriously reduces people's chances of escape from the fire scene.

[0042] The operating principle of the present invention is now described as follows: when a fire occurs in a building, the fire will produce a large amount of thick smoke. The thick smoke rises and gathers at a high place under the action of hot air, so that it will be detected by the smoke sensor 3. The smoke sensor 3 will send an electrical signal to the PLC controller 24. After receiving the electrical signal, the PLC controller 24 will first control the low-level lighting lamp 4 and the high-level lighting lamp 2 to work at the same time, and control the positioning electric push rods 19 on the left and right sides to work, so that the positioning electric push rods 19 retract, thereby releasing the fixation between the lifting frame 172 and the card plate 18, and then the PLC controller 24 controls the working motor 22 to work until the set time, and the working motor 22 drives the winding roller 21 to rotate, so that the air supply pipe 23 wrapped around the outside of the winding roller 21 is transported downward, and the air supply pipe 23 drives the lifting frame 172 to move downward to the set position, and then the PLC controller 24 controls the regulating valve 27 to open, and the low-level lighting lamp 4 can illuminate the objects on the ground to assist people to evacuate better;

[0043] When the smoke inside the corridor of the building is particularly thick and affects people's breathing, people can bend over and walk to the low lighting lamp 4, remove the mask 5 from the lifting frame 172, and wear it on the face mouth and nose. When the mask 5 is removed from the lifting frame 172, the mask 5 will drive the insulating plug plate 40 to disengage from the slot 39, and the conductive block 42 in the placement slot 41 will contact the conductive plate 43 under the action of the spring elastic force. The conductive block 42 is electrically connected to the external power supply, and the conductive plate 43 is electrically connected to the corresponding electromagnetic block 38. When the conductive block 42 and the conductive plate 43 are in contact, an external current will be transmitted to the electromagnetic block 38, so that the electromagnetic block 38 is energized to generate magnetic force, and the electromagnetic block 38 will attract the permanent magnet block 36 to move, so that the permanent magnet block 36 drives the support plate 35 and the rubber plate 332 to move, so that the rubber plate 332 is separated from the horizontal slot 34, and the oxygen cylinder 261 The oxygen in the air will be transported to the air delivery chamber 30 through the oxygen tube 262, the winding roller 21 and the air delivery tube 23, and then transported to the mask 5 through the short tube 31 and the second serpentine hose 32, so that people can breathe oxygen. Then, people can push the telescopic rod 45 upward, and the telescopic rod 45 will drive the lighting box body 1 and the upper hanging plate 46 to move upward through the fixed frame 44, so that the upper hanging plate 46 and the lower hanging plate 48 are separated, and the lighting box body 1 can be removed from the wall as a temporary flashlight. In addition, the lighting box body 1 is light in weight and convenient for people to carry. When people evacuate in the corridor, they can use the lighting box body 1 to illuminate the road ahead while breathing oxygen, avoiding people from inhaling a large amount of harmful gases in a short time and fainting when evacuating quickly in the corridor, thereby reducing the probability of people escaping from the fire scene.

[0044] When the PLC controller 24 detects smoke through the smoke sensor 3, the PLC controller 24 will also control the air pump 61 to start working. The air pump 61 transmits the external gas filtered by the filter 7 to the cylinder through the first serpentine hose 62. At this time, the vent 14 and the dust cleaning port 10 are in an aligned state, and the external gas will be output through the vent 14 and the dust cleaning port 10. Then the PLC controller 24 controls the first linear motor 8 to work, and the first linear motor 8 will drive the cylinder to work up and down. The cylinder cleans the smoke particles on the surface of the high-altitude lighting lamp 2 through the bristles 11. At the same time, the cleaned smoke particles are blown away by the high-speed airflow. When the lighting box body 1 is taken down from a high place by people Afterwards, the operator can send an electrical signal to the PLC controller 24 by pressing the control button on the surface of the telescopic rod 45. After receiving the electrical signal, the PLC controller 24 will control the reduction motor 12 to drive the adjustment cylinder 13 to rotate to the set angle, so that the strip hole 15 and the air outlet 16 are aligned, and the air vent 14 and the cleaning port 10 are staggered. The gas delivered by the air pump 61 will be discharged through the air outlet 16, blowing away the smoke in front of the lighting box body 1, making it convenient for the operator to illuminate the road for evacuation. A backup power supply 25 is provided inside the installation box 171, which can provide power for the air pump 61 and the high-altitude lighting lamp 2.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
