Problems solved by technology
Such energy-saving devices relying on electrical technology are susceptible to interference from elevator internal circuits
Another example is the Chinese patent with the patent number "201120072170.2" and the patent name "car-type elevator energy recovery device" using supercapacitor technology, which proposes to use the downward motion of the elevator to drive power generation and work. The backstop device is severely worn and has a short lifespan, requiring regular replacement

The invention provides an energy-saving safety device mounted on an elevator. The energy-saving safety device comprises first piston rods, second piston rods, an air box, a first electromagnetic reversing valve, a one-way valve, an impeller casing, a closed coil, an energy storage device, a clutch, a second electromagnetic reversing valve, a motor and an electromagnetic clutch. One end of each first piston rod and one end of each second piston rod are connected with a car body. The other end of each first piston rod and the other end of each second piston rod are connected with a multistage telescopic air cylinder. The multistage telescopic air cylinders are connected with the top end of the air box. The first electromagnetic reversing valve and the second electromagnetic reversing valve are located on the two sides of the air box. The one-way valve is located at the bottom end of the air box. The one-way valve, the clutch and the electromagnetic clutch are all connected with the impeller casing. The closed coil and the energy storage device are both connected with the clutch. The motor is connected with the electromagnetic clutch. The energy-saving safety device can effectively recycle the gravitational potential energy of an elevator car, energy is saved, and a power generation device is simple and long in service life.
Description
technical field [0001] The invention belongs to an energy-saving safety device installed on an elevator, in particular to a safety and energy-saving device that uses a telescopic cylinder to complete power generation and protection. It can be used in various passenger compartment elevators and belongs to the technical field of elevators. Background technique [0002] With the development of modern technology, the elevator has become more and more popular as a convenient tool, because it can not only make it easier for the elderly, children, and disabled people to go up and down the stairs, but also help to carry freight. However, with the continuous growth of the urban population, in some big cities such as Beijing and Shanghai, some passengers have to wait for the elevator during the peak period, and the waiting time is usually longer. During this period of time, the passengers waiting can only take out their mobile phones, and the current mobile phones generally consume po...
