The numbers in the figure represent: 10. the elevator car running shaft comprises a car running shaft body, 11 car passenger carrying openings, 20 buffer water tanks, 21 buffer tank openings, 22 soft tank covers, 220 tear-and-break broken edges, 23 impact air reduction grooves, 24 closed partition plates and 25 automatic water charging pumps.

Detailed Description

Referring to fig. 1 in combination with fig. 2, the water and gas buffer elevator shaft of the present embodiment includes a car moving shaft 10, a buffer water tank 20 is disposed at the bottom of the car moving shaft 10, a buffer tank opening 21 communicated with the car moving shaft 10 is disposed at the top of the buffer water tank 20, a soft tank cover 22 is disposed in the buffer tank opening 21, an inner cavity of the buffer water tank 20 is filled with water, a drop impact gas groove 23 is disposed on an inner wall of the buffer water tank 20, a closed partition 24 is disposed at a notch of the drop impact gas groove 23, and the closed partition 24 has good elasticity.

During specific implementation, the car operation well 10 is vertically arranged in a building, a plurality of car passenger carrying openings 11 are formed in the wall of the car operation well 10, and people can enter and exit the elevator car through the car passenger carrying openings 11.

During specific implementation, the buffer water tank 20 is made of concrete or steel and is firmly and stably arranged at the bottom of the car operation shaft 10, and the size of the buffer tank opening 21 is consistent with the size of the inner cavity of the car operation shaft 10, so that the elevator car can directly enter the buffer water tank 20 from the car operation shaft 10.

During the concrete implementation, buffer tank 20 is equipped with the degree of depth between one meter five to two meters, can effectively reduce elevator car's the impact force that falls, can alleviate the injury that personnel received when directly falling again.

The buffer water tank 20 is provided with an automatic water filling pump 25, and the automatic water filling pump 25 is provided with a water level control switch.

During specific implementation, the water inlet pipe of the automatic water filling pump 25 is connected with a water source, the water conveying pipe is introduced into the inner cavity of the buffer water tank 20, and the water level control switch takes the water level in the buffer water tank 20 as a working signal, so that the buffer water tank 20 is always in a state of being filled with water.

The soft box cover 22 has good elasticity and is hermetically connected with the buffer box opening 21 at the periphery.

In specific implementation, the water level in the buffer water tank 20 is kept in the middle of the buffer tank opening 21, and the soft tank cover 22 is made of soft plastic with better elasticity and is flatly laid on the water surface, so that moisture can be prevented from entering the car operating well 10 upwards, and falling objects cannot directly collide with hard objects to be seriously damaged.

The periphery of the soft case cover 22 is provided with a tearing and breaking edge 220.

In specific implementation, the soft box cover 22 is hermetically connected with the buffer box opening 21 through the tearing and breaking edge 220. Normally, the tearing and breaking edge 220 and the soft case cover 22 are connected into an integral state, and the tearing and breaking edge 220 and the soft case cover 22 are disconnected only when the middle part of the soft case cover 22 is impacted by a falling object. When the soft box cover 22 is impacted by a falling object, the falling object is wrapped on the bottom surface of the falling object and is flushed into water, so that the falling object can be injured when impacted, and the impact force can be reduced rapidly by matching with the water body.

The impact reducing air groove 23 is concavely embedded in the inner wall of the box body of the buffer water tank 20, and the closed partition plate 24 is hermetically arranged on the notch of the impact reducing air groove 23.

During specific implementation, a plurality of impact air reduction grooves 23 are formed in the periphery of the inner wall of the box body of the buffer water tank 20, each impact air reduction groove 23 is filled with air, and the closed partition plate 24 is made of a material with good elasticity. When the elevator car falls down from a high place to the buffer water tank 20, a huge impact force is generated, water in the box firstly rushes to the four walls of the box under the action of the impact force, and then gushes upwards from the periphery of the car, so that the car slowly descends to the bottom of the buffer water tank 20, and the injury of the impact force on people in the car is relieved. When the impact-reducing air groove 23 is impacted by water power, the closed partition plate 24 is quickly recessed into the inner cavity of the air groove and extrudes air in the air groove, so that the damage of impact force when the lift car contacts the water surface is relieved.

When a human body falls down from a high position to the buffer water tank 20, the human body falls onto the soft tank cover 22 firstly, and the tearing and breaking edges 220 around the soft tank cover are torn and broken, so that the soft tank cover 22 is wrapped at the bottom of the human body and rushes to the water bottom together with the human body, the contact surface and the friction force between the human body and water can be increased to reduce the downward impact force, and the injury caused by the impact of the human body on the water surface can be reduced.

In summary, the following steps: the problem that prior art elevartor shaft buffer can not effectively dissolve the impact force of falling and the safety of the protection personnel of falling is solved to this embodiment, provides an utilize aqueous vapor buffering elevartor shaft of water and gas as the buffer.
