Safety protection device of elevator

Abstract

The invention discloses a safety protection device of an elevator. The safety protection device comprises an elevator car, and a ventilation device is arranged on one side of the top of the elevator car; a control cabinet is arranged on the other side of the top of the elevator car; a microprocessor is arranged in the control cabinet; the microprocessor is connected with a fault sensor and a danger alarm, and controls the fault sensor and the danger alarm; the danger alarm is connected with a loudspeaker arranged on the top side of the elevator car; a damping device is arranged at the bottom of the elevator car; airbags are arranged on the lower side of the damping device; the airbags comprise airbag controllers; the airbag controllers are connected with an infrared induction device arranged on the outer surface of the elevator car; and an elastic protection device is arranged at the bottom of an elevator shaft. The safety protection device of the elevator has the beneficial effects that ventilation can be achieved when the elevator breaks down, intelligent control is achieved, safety measures are taken, damage of elevator falling to human bodies can be effectively reduced, the structure is simple, cost is low, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an elevator safety protection device. Background technique [0002] The buildings in modern cities are getting higher and higher, and taking an elevator is almost indispensable for everyone to go home, work, and go shopping. The body of the elevator is called a car, and the car is usually equipped with a support plate, which divides the car into upper and lower layers. The upper layer is used to support the people who take the elevator, and the lower layer is used to place various equipment. However, various elevator crashes were exposed, and elevator failures occurred frequently. When the elevator breaks down, there are often two situations that cause the greatest harm to the passengers. One is that when the elevator falls rapidly, the elevator hits the bottom of the pit, and the strong impact force that occurs causes damage to the passengers. The second is that when t...

However, various incidents of elevator crashes have been exposed, and elevator failures have occurred frequently

When the elevator breaks down, there are often two situations that cause the greatest harm to the passengers. One is that when the elevator falls rapidly, the elevator hits the bottom of the pit, and the strong impact force will cause damage to the passengers.

The second is that when the elevator falls, it is often accompanied by a power outage, which makes the ventilation device of the elevator invalid, resulting in the airtightness of the elevator, and the oxygen in the elevator is gradually consumed, resulting in hypoxia and suffocation.
