An elevator with automatic alarm and rescue

Abstract

The invention discloses an elevator capable of automatically alarming and rescuing. The elevator comprises a temperature sensor, an ion type smoke sensor, an alarming device and a lift well spraying device, wherein the temperature sensor is mounted on the outer wall of a lift cage or outside a lift cage door; the ion type smoke sensor is mounted on the outer wall of the lift cage or outside the lift cage door; the alarming device is connected with the temperature sensor and the ion type smoke sensor; the lift well spraying device is connected with the temperature sensor and the ion type smoke sensor, and comprises a water pump, water pipes and spray heads; the water pump is connected with a running water source; the water pipes are connected with the water pump, and are laid in the extending direction of a lift well; one or more spray heads connected with the water pipes are mounted in each storey; and an air filtering device is arranged in a ventilating device to be used for purifying air to enter the lift cage. Through the adoption of the elevator disclosed by the invention, high-temperature environment caused by fires can be relieved, and massive smoke and dusts can be avoided from entering the lift cage.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator capable of automatic alarm and rescue. Background technique [0002] When a high-rise building encounters a fire, the main power supply of the elevator is cut off. If there are still people in the elevator who have not escaped in time, they will be trapped in the car, and the smoke and dust generated by the fire can enter the car along the shaft or the car door. Therefore, in addition to facing various safety problems that may occur in the elevator, the elevator riders must also take precautions against the smoke and dust entering the car. Fire statistics show that 60% to 80% of the deaths in fires are related to the smoke in the fire. The smoke and dust are mainly mixed toxic gases such as carbon monoxide, carbon dioxide, water vapor, sulfur dioxide and phosphorus pentoxide, which are inhaled by the human body. Prone to poisoning death. Existing elevator ventilation equipm...

AI Technical Summary

Problems solved by technology

Existing elevator ventilation equipment is generally connected with the air in the shaft. Although it can maintain the air circulation in the car, it cannot guarantee the quality of the air passing into the car, so that it cannot prevent the smoke and dust from the fire from harming the trapped people.

Moreover, existing elevators generally only have alarm measures in a fire, and there are no other measures to reduce the impact of fire.
