Description

skydiving

technical field

The invention relates to the fire emergency lifesaving field, in particular to a high-rise lifesaving parachuting.

Background technique

With the pace of urbanization in China, people flock to cities one after another, and high-rises, super high-rises, and skyscrapers have sprung up. However, the supporting fire-fighting and life-saving measures and fire-fighting and life-saving appliances are still quite scarce. Once a fire breaks out, it is very difficult to evacuate and fight the fire, often causing serious consequences of mass death and mass injury.

Known high-rise lifesaving mainly has three ways: one is to go down step by step through the evacuation stairs, but it is time-consuming and laborious, especially when the road is blocked by fireworks, people cannot escape from normal channels; However, it is difficult for aerial ladder vehicles and curved-arm high-spray vehicles to reach the height of the floor to be rescued, resulting in difficulties in rescue. In addition, aerial ladder vehicles over 100 meters are expensive, bulky, and slow to move, especially in narrow roads and large traffic flows. The city cannot reach the rescue site in time; the third is the helicopter, but the helicopter will be restricted by dust, hot air, thick smoke and other aspects. Chinese patent CN102068765A discloses a high-rise lifesaving method, which includes using flying backpacks to quickly send rescuers to the target floor; helping trapped people wear parachutes, and helping them get out of danger, and opening parachutes; Airbags help to land and avoid personal injury. However, this method requires the assistance of the rescuers, and the trapped persons are likely to fall outside the inflatable airbags and be injured when they land. How to effectively reduce the casualties of high-rise fires mainly depends on self-rescue. High-rise lifesaving skydiving solves this problem well. However, existing high-rise life-saving skydiving requires special training, especially low-altitude skydiving, and the time of staying in the air is short. It is difficult for untrained people to do various technical actions in an orderly manner, and it is extremely easy to make mistakes and cause accidents. In addition, there are many high-rise buildings in the city, and the airflow between the buildings is very turbulent. Blind skydiving in the event of an emergency is easily disturbed by the turbulent airflow, causing various accidents such as deviation from the direction, hitting the building, entanglement of the parachute rope, and even failure to open the parachute. .

detailed description

The present invention will be further explained and described through specific embodiments below, but it does not mean to limit the protection scope of the present invention.

The high-rise lifesaving parachute jumping of the present invention comprises umbrella cover (33,34), umbrella stand 31, backpack 2, as shown in Figure 1. Umbrella stand 31 adopts semi-rigid material to make, and one end of umbrella stand 31 is concentrated and fixed on backpack 2 top, and the other end of umbrella stand 31 is fixed on the umbrella surface (33,34), and umbrella surface (33,34) comprises wing surface 33 And a plurality of fins 34 closely attached to the airfoil 33 and distributed along the span direction, the fins 34 can be compressed and folded in an "M" shape along the span direction, as shown in FIG. 2 . Inside the backpack 2 is provided with an intelligent control system 22, the intelligent control system 22 can control the opening and closing of the umbrella surface (33, 34), and the start switch 5 of the intelligent control system 22 is installed on the shoulder strap 21 of the backpack 2. Preferably, the umbrella surfaces (33, 34) are arc-shaped along the spanwise direction and in the direction perpendicular to the spanwise direction. Further, the umbrella stand 31 is an automatically retractable umbrella stand 31, and an elastic protective film 6 is arranged on the side of the backpack 2 close to the human body 1. The area of the protective film 6 is larger than that of the umbrella surface (33, 34) after being compressed and folded when the backpack 2 is close to the human body. The projected area of one side of the backpack 2 may be greater than the projected area of the head of the human body 1 on the side of the backpack 2 close to the human body 1 .

As an improved technical solution of the present invention, an inflatable airbag 4 is fixed at the bottom of the backpack 2, as shown in FIG. 3 . The inflation method of the inflatable airbag 4 mainly includes three types: one is that a blower 23 is arranged in the backpack 2, and the intelligent control system 22 controls the blower 23 to inflate the airbag 4; , the intelligent control system 22 controls the container 23 that compressed gas is housed to inflate the air bag 4 quickly; the third is that solid sodium bicarbonate is housed in the air bag 4, and the container 23 that is equipped with dilute hydrochloric acid is arranged in the backpack 2, and the intelligent control system 22 Control the container 23 that dilute hydrochloric acid is housed to open and pour dilute hydrochloric acid in the air bag 4. Among them, the first method has a slow inflation speed and easily disturbs the airflow around the skydive, but its cost is low and its structure is simple; the second method has a fast inflation speed, but its cost is high and its structure is complicated, and the compressed gas will occupy a larger volume of the backpack 2 The third way is fast inflating, low in cost, simple in structure, occupies a small volume of the backpack 2, and will not disturb the airflow around the skydiving, so it is the best mode of the present invention, and it is also the first time that the inventor proposes that in the skydiving process Inflates using a chemical reaction. Further, the airbag 4 is in a compressed state before being inflated, and is in an "L" shape after inflating. The bottom of the backpack 2 both sides is respectively hinged with an "L" shaped air bag shelving plate 24. When the air bag 4 is in a compressed state, the air bag shelving plate 24 accommodates the air bag 4 therein. Turn sideways to release airbag 4 downwards. Wherein, 25 is hinge pivot. More preferably, the airbag 4 is in a "J" shape after being inflated. When the airbag 4 is fully inflated, the protrusion 41 in front of the airbag 4 will push the feet of the human body 1, so that the person's buttocks fall into the depression 42 beside the protrusion 41, that is, the parachutist sits in the "J"-shaped depression. 42, thereby reducing the center of gravity of the skydivers, preventing the airbag 4 from bouncing and tripping people after touching the ground, thereby further increasing the safety of the skydivers.

All the steps of the present invention are completed by the intelligent control system 22 provided inside the backpack 2, and the parachutist only needs to start the start switch 5 on the shoulder strap 21 to get final product. It should be noted that the backpack 2 is equipped with measuring instruments such as an altimeter, which are used to help the intelligent control system 22 to measure, make it respond in real time, and start corresponding operations.

For example, when people parachute, they only need to put the backpack 2 shoulder straps 21 on their shoulders like a primary school student, hold the backpack 2 shoulder straps 21 tightly with both hands, then start to jump and press the start switch 5 on the shoulder straps 21 . The intelligent control system 22 controls the umbrella stand 31 to extend upwards and then rotate to both sides, thereby launching the umbrella surface (33, 34). After the parachutist descends to a certain height, the intelligent control system 22 controls the blower 23, the container 23 containing compressed gas or the container 23 containing dilute hydrochloric acid to inflate the airbag 4, and the airbag 4 extends downward and pushes away the "L" type airbag resting plate 24, the protrusion 41 in front of the air bag 4 will push the feet of the human body 1, so that the people's buttocks fall into the depression 42 on the side of the protrusion 41, that is, the skydivers sit in the depression 42 of the "J" shape place, so that the airbag 4 fully supports the parachutist. Of course, the airbag 4 is in an "L" shape after being inflated, and a similar effect can also be achieved. After the airbag 4 touches the ground, the intelligent control system 22 controls the umbrella stand 31 to rotate and gather the umbrella surface (33,34) in the middle, and then compresses downwards to shorten the height of the umbrella stand 31, so that the umbrella stand 31 and the umbrella surface (33,34 ) after contraction, the projected area on the side of the backpack 2 close to the human body 1 is not larger than the elastic protective film 6 arranged on the side of the backpack 2 close to the human body 1, as shown in FIG. 4 . Since the umbrella stand 31 is semi-rigid, and the elastic protective film 6 has elasticity, even if it hits the human body 1, it will not hurt the human body 1 . It should be noted that all materials in the present invention are made of high temperature resistant and flame retardant materials.
