Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a fireproof safety elevator. Background Art

[0002] Vertical lifts are the most widely used type of elevators. When a fire occurs in the corridor, a large amount of heat and smoke will be generated. Since the interior space of the elevator car is relatively closed, the temperature inside the elevator car will be too high, posing a certain hidden danger to the safety of people inside the elevator car.

[0003] Prior art, such as publication number CN218879077U, provides a fireproof safety elevator, including an elevator car, the surface of the elevator car is provided with a fireproof layer, and the right side of the inner cavity of the elevator car is fixedly connected with a device cylinder. The utility model relates to the field of safety fire prevention technology. The fireproof safety elevator car starts the left electromagnetic valve to allow the water inside the water storage tank to be introduced into the inside of the water spray pipe through the water pipe, and then the water is converted into water mist by the electric atomizing nozzle to spray out, so that the inside of the elevator car is cooled to a certain extent, and the air outside the elevator car is blown into the vent by starting the fan, and the toxic air outside is filtered to a certain extent through the air filter plate, and the air entering the elevator car is cooled by the water mist, so that when the outside is on fire, the personnel inside the elevator car can be protected to a certain extent, and the body of the personnel inside the elevator car is effectively avoided from being injured due to the excessive temperature inside the elevator car and smoke poisoning.

[0004] In this solution, when a fire occurs, the fireproof layer outside the elevator car is used to provide certain protection for the people inside the elevator car. By starting the solenoid valve on the left, the water inside the water tank is introduced into the inside of the water spray pipe through the water pipe, and then the water is converted into water mist through the electric atomizing nozzle to spray out, so that the inside of the elevator car is cooled to a certain extent to avoid excessive temperature inside the elevator car, which may cause physical injuries to the people inside the elevator car. However, in the event of an actual fire, the high temperature caused by the fire is likely to cause these electrical equipment to malfunction and fail to cool down, which places high demands on the use scenario. In view of this, we propose a fireproof and safe elevator. Utility Model Content

At this time, the tension of the gas spring will push the sealing plate to slide, so that the drainage groove is connected with the water outlet groove, and the coolant in the water tank is discharged to cool down the interior of the elevator car, so as to avoid more harm to the human body due to the high temperature inside the elevator car, and to avoid the problem of failure due to high temperature when some electrical equipment is used for cooling.

[0009] Preferably, a first PS plastic support frame is fixedly connected to the top of one side of the elevator car, and the traction rope passes through the inner wall of the first PS plastic support frame. By respectively arranging the first PS plastic support frame and the second PS plastic support frame above and below the elevator car, no matter whether the high temperature spreads from above or below, the pulling of the traction rope on the sealing plate can be softened in time to facilitate timely cooling.

By setting the cooling mechanism 2, if a fire occurs when there are people inside the elevator car 1, the high heat outside the elevator car 1 will soften the second PS plastic support frame 23 after being heated, and lose the support for the traction rope 24. At this time, the traction rope 24 is in a loose state, making the traction rope 24 The pulling force on the sealing plate 214 disappears. At this time, the tension of the gas spring 216 will push the sealing plate 214 to slide, so that the drainage groove 211 is connected with the water outlet groove 215, and the coolant in the water tank 21 is discharged to cool the interior of the elevator car 1 to avoid more harm to the human body due to the high temperature inside the elevator car 1. In order to avoid the problem of high temperature failure when using some electrical equipment for cooling, a first PS plastic support frame 22 is fixedly connected to the top of one side of the elevator car 1. The traction rope 24 passes through the inner wall of the first PS plastic support frame 22. By respectively arranging The arrangement of the first PS plastic support frame 22 and the second PS plastic support frame 23 allows the high temperature to be softened in time and the pulling of the traction rope 24 on the sealing plate 214 to be released no matter whether the high temperature spreads from the top or the bottom, so as to facilitate timely cooling.

[0033] When a fire-proof safety elevator of the utility model is in use, a fire occurs when there are people inside the elevator car 1. The high temperature outside the elevator car 1 will soften the second PS plastic support frame 23 after being heated, and lose the support for the traction rope 24. At this time, the traction rope 24 is in a loose state, so that the pulling force of the traction rope 24 on the sealing plate 214 disappears. At this time, the tension of the gas spring 216 will push the sealing plate 214 to slide, so that the drainage groove 211 is connected with the water outlet groove 215, and the coolant in the water tank 21 is discharged, so as to cool the interior of the elevator car 1, and the The first PS plastic support frame 22 and the second PS plastic support frame 23 are respectively arranged above and below the elevator car 1, so that no matter whether the high temperature spreads from the top or the bottom, it can be softened in time to release the pulling of the traction rope 24 on the sealing plate 214, so as to facilitate timely cooling. By arranging the guide inclined plate 212, the coolant discharged from the drainage groove 211 can flow along the water absorption groove 11 on the inner wall of the elevator car 1, and the water absorption groove 11 has a larger surface area. Due to the tension of the liquid itself, it can better adhere to the inner wall of the water absorption groove 11 to improve the cooling effect.
