Even if corresponding safety technology education is carried out on high-altitude operation and high-risk personnel and traditional labor and defense articles and high-altitude operation safety protection facilities are equipped before engineering construction activities are carried out, the safety accident rate can only be reduced, safety control within a certain degree range is realized, and zero accidents in safety production are difficult to realize.

Especially, in case of emergency dangerous situations (such as tower crane overturn, scaffold instability and the like) during high-altitude operation, operators are difficult to make effective response and self-protection within a very short time, so that the accident rate of high-altitude operation and high-risk personnel is high and the accidents are accompanied with personal injuries and deaths. At present, in daily production activities in the engineering construction industry, the traditional labor and defense articles are provided for the high-altitude operation and high-risk personnel, and effective personnel safety protection facilities or devices for dealing with emergency dangerous situations are also lacked, so that the accident rate and the death rate caused by the emergency dangerous situations of the high-altitude operation and the high-risk personnel during the high-altitude operation are reduced, and the personal and property safety is finally guaranteed.

At present, the device which can play a role of high-fall protection when high-altitude operation and high-risk personnel are in emergency dangerous situations (such as tower crane overturn, scaffold instability and the like) and the personnel are in a falling state and the patent numbers thereof are as follows: high-altitude falling protection devices (CN 106730431A, CN106730431B and CN 206285358U), a high-altitude falling protection device and a working method thereof (CN 109224338A).

Although the structure, the working mechanism and the appearance of the various high-altitude falling protection devices are very different and complicated, the high-altitude falling protection devices can achieve certain falling protection when high-altitude operation and high-risk personnel have a dangerous falling condition and the personnel are in a falling state, so that the personal casualty rate of the high-risk personnel is reduced, but zero casualty and comprehensive protection of the falling personnel cannot be thoroughly realized.

The high-altitude falling protection device comprises a high-altitude falling protection device (CN 106730431A, CN106730431B and CN 206285358U), wherein after the high-altitude falling protection device is worn on a high-altitude operation and high-risk personnel, when the personnel have high falling danger and are in a falling state, a three-axis acceleration sensor in a backpack detects that the acceleration of the personnel is gravity acceleration, the sensor sends a signal to a main control circuit, the main control circuit controls an ignition driving circuit to drive an igniter to ignite, the igniter and a gas generating agent are ignited to form a large amount of gas to inflate a safety airbag, and the fully inflated airbag forms a safety airbag to protect the personal safety of the falling personnel and reduce falling damage. But it also has the following technical shortcomings:

(1) the device has more parts and complex structure, can be put into use only after being entrusted to a professional manufacturer for customized assembly, and has higher manufacturing cost and poorer economy;

(2) when the dangerous situation that falls takes place for personnel, the device inflates air bag fast to wearing the back in personnel and forming huge protection airbag, and the control box is located air bag's central point and puts, when the posture of falling of personnel is face-up back of the body down, air bag can play the protection and will fall the injury and reduce to minimumly to falling personnel, if the posture of falling is face-down back of the body up, air bag can't protect personnel, personnel and ground direct contact and initiation casualty accident, so there are serious leak and potential safety hazard in the device protection mechanism. In addition, the control box and the safety airbag are on the same side, when the safety airbag and the control box simultaneously contact the ground and bear the reaction force of the ground, the control box and the internal storage battery, the undervoltage indicator lamp, the fault indicator lamp, the main control circuit, the safety airbag detection circuit and other electric elements are easy to impact or extrude and damage when being subjected to the reaction force of the ground, the control box and the internal storage battery, the undervoltage indicator lamp, the fault indicator lamp, the main control circuit, the safety airbag detection circuit and other electric elements cannot be reused, and the structural design also has a leak;

(3) the device has higher requirement on the application environment, and various electrical elements and ignition agents and gas generating agents for gas generation contained in the device are easily affected by the action of a rainy and humid environment to cause the problems of damp deterioration, short circuit or corrosion and the like, and finally, the parts can not normally operate to cause the failure of the whole device, so the device is only suitable for a dry environment, has a narrow application range and has poorer universality;

(4) because the device is carried on the back or the abdomen of a person, and contains a large number of parts and has large self-weight, when the person works, the device is easy to increase the burden of the person, consume the physical strength and the energy of the person, reduce the working efficiency of the person and have poor social benefit.

Secondly, be a high altitude protection device that falls and working method (CN 109224338A), when the human body that falls appears above the protection network, through human detection module with human information transmission to the control module that falls, control module output control protection network motion module again to start the protection network switch and make and drive the protection network installation department through compression spring resets and pop out along horizontal guide bar, the protection network that falls also expands along the wall body reentrant corner simultaneously, in order to catch the human body, plays safety protection's effect. But it also has the following technical shortcomings:

(1) in the device, a protective net mounting part, a protective net moving module, a protective net switch and other main high-fall protection parts are appointed to be mounted in internal corners of two layers of walls of an outer vertical surface of a building, and meanwhile, a human body detection module is appointed to be mounted in internal corners of more than four layers of walls of the outer vertical surface of the building;

(2) the device contains a plurality of parts and is complex in structure, a professional manufacturer must be entrusted to customize, produce and transport the device to the site for installation and debugging, and then the device can be put into use, so that the manufacturing and using cost is high, the economy is poor, meanwhile, the installation space needs to be reserved on the internal corner of the external wall, the requirement on the use environment condition is high, and the universality is poor;

(3) the device supports falling personnel through the protective net after identifying falling personnel information, surrounds the falling personnel in a limited space by means of the internal corners of three sides of the wall body, and protects personal safety, but the opposite sides of the internal corners of the wall body are open faces and have no horizontal protective measures, so that the falling personnel can fall out from the open faces, personal safety accidents are easily caused, and therefore, the protection mechanism of the device has leak and potential safety hazards, the use risk is high, and comprehensive protection cannot be formed;

(4) the device and each spare part are because of installing in each floor of outer wall reentrant corner, and the supporting maintenance work degree of difficulty and the work load of its daily use are all great, and the maintenance in-process need be with the help of equipment of ascending a height to there exist operation and corresponding risk of emiting, its maintenance cost is higher and the safety risk is great.

Therefore, how to realize effective self-safety protection of operators, expand the types of self-safety protection facilities of high-altitude falling personnel, optimize and perfect self-protection modes, application scenes and self-protection mechanisms aiming at high-altitude falling personnel, and simplify the structure and the use method of the safety protection device becomes a technical problem which needs to be solved urgently by technical personnel in the field.

after the storable rubber bladder 15 is uninflated, the storable rubber bladder 15 is expanded into a tubular structure having a length greater than the height of the user, and the user is placed in the inner cavity of the storable rubber bladder 15;

the safety harness 13 includes shoulder straps for fixing the shoulders of the user, leg straps for fixing the legs of the user, and a safety harness built-in fixing surface 18 for fixedly connecting with the stowable rubber airbags 15;

at least one safety device vent hole 17 is arranged at the position of the two end openings of the storable rubber air bag 15;

each safety device exhaust hole 17 comprises a safety device exhaust hole reducing inner cavity 21, more than three exhaust hole outer fan-shaped blades 22 and more than three exhaust hole inner fan-shaped blades 20 which are respectively arranged at the port parts at two ends of the safety device exhaust hole reducing inner cavity 21;

the reducing inner cavity 21 of the safety device exhaust port is a reducing inner diameter hole which is close to the inner diameters of the two end parts and is larger than the inner diameter of the middle part; wherein, an outward sinking shoulder towards the outside of the rubber air bag 15 and an inward sinking shoulder towards the inside of the rubber air bag 15 are formed between the two end parts with larger diameter and the middle part with smaller diameter;

and a connecting spring 19 of the fan-shaped blade on the inner side of the air outlet is arranged between one surface of the fan-shaped blade 20 on the inner side of the air outlet reducing inner cavity 21 of each safety device and the corresponding inward sinking shoulder.

The utility model has the following using method and working mechanism:

before the user operation, it must dress at present subaerial the utility model discloses, will have received folding can accomodate air bag 15 and penetrate to the health middle part and dress at the waist temporarily from the personal underfoot, wear arm and both legs after passing arm and both legs respectively with safety device braces 13 shoulder and leg strap simultaneously between shoulder and both legs, ensure that safety device dresses firmly and next to the shin, on this basis, the operation personnel alright with begin to scramble and develop high altitude construction.

When a user carelessly slides to fall or the operation platform where the user is suddenly unstable and overturns during high-altitude operation, the carbon dioxide is input into the rubber air bag 15 by operating the gas generator 16, in the process, the liquid carbon dioxide enters the normal-temperature normal-pressure environment in the rubber air bag from the high-pressure low-temperature environment in the original storage tank, so that the carbon dioxide is gasified into carbon dioxide gas from the liquid state after undergoing a gasification reaction, namely the liquid carbon dioxide absorbs heat in the rubber air bag, when the carbon dioxide is gasified, the volume of the carbon dioxide gas is expanded by about 450-640 times, namely the conversion rate of the liquid carbon dioxide to the gaseous carbon dioxide per minute is 189-269L/min, and after absorbing a large amount of heat, the internal temperature of the rubber air bag 15 is reduced to a lower value, and the burst of the air bag 15 caused by overhigh internal temperature and pressure of the air bag when the rubber air bag is used in hot and high-temperature weather or under the environment is avoided. After the liquid carbon dioxide enters the rubber air bag 15, the gasification speed is very high, the inner space of the rubber air bag 15 can be filled with gas in a short time, at the moment, a person only needs to lift two arms, the rubber air bag 15 filled with gas can wrap around the whole body of the person to carry out all-round protection, and openings can be formed at the two ends of the tail end of the rubber air bag 15, so that the person can escape for self and breathe conveniently. When the personnel are protected in all directions in a wrapping mode by the rubber air bags 15 filled with air, the rubber air bags 15 are the parts which are firstly contacted with the ground, and any part of the whole human body cannot be contacted or collided with the ground, so that the possibility of casualties of falling personnel at high altitude is avoided.

When the personnel and the rubber air bag 15 wrapped by the personnel stably land, the personnel can take off the safety device braces 13 containing shoulder straps and leg straps by themselves in the air bag and climb out from the openings at the two ends of the tail of the rubber air bag 15 to escape, thereby realizing effective self rescue. If the personnel and the stable landing back of being wrapped up in rubber air bag 15 with it, there is barrier or heavy object shutoff opening in rubber air bag 15 periphery, personnel still can follow another opening part and flee for one's life, and the rubber material of rubber air bag 15 possesses fine bursting strength and elasticity, strong pliability in addition, and the impact damage, tear resistance, wearability resist promptly, can resist the impact and the oppression of heavy object to provide sufficient safety protection space for the operation personnel in rubber air bag 15 simultaneously, avoid personnel to receive the oppression of heavy object or impact and be injured.

In addition, the rubber air bag 15 filled with air has smaller density and large volume due to the carbon dioxide gas inside the rubber air bag 15, so that the rubber air bag 15 has huge buoyancy, even if a person falls into the water surface, a lake or the sea together with the wrapped rubber air bag 15, the person can be supported by the water surface under the action of the huge buoyancy generated by the person, at the moment, the person only needs to take off the safety device straps 13 by oneself according to the above, the shoulder straps and the leg straps are contained, and the person climbs out and escapes from the openings at the two ends of the tail of the rubber air bag 15, so that the self-rescue can be realized, the amphibious is really realized, the universality and the practicability of the person are enhanced, and the structure, the safety, the protection performance and the working mechanism of the protection device are reasonable and feasible, and the protection device has no potential safety hazard and use risk and is worthy of popularization.

The safety device exhaust port 17 arranged at the two ends of the ending part of the rubber air bag 15 is also optimally designed and considered, in order to prevent the phenomenon that the carbon dioxide gas filled in the rubber air bag 15 is excessively exhausted through the exhaust port 17 and cannot be effectively protected for a long time when a person falls and contacts the ground or the rubber air bag 15 is pressed or impacted by a heavy object, the structure of the safety device exhaust port 17 particularly adopts a reducing inner cavity structure, when the rubber air bag 15 is acted by external force, the carbon dioxide gas in the air bag extrudes the inner fan-shaped leaf sheet 20 of the exhaust port in advance and compresses the inner fan-shaped leaf sheet connecting spring 19 of the exhaust port, so that the inner fan-shaped leaf sheets 20 of the three exhaust ports bend outwards and synchronously open the original splicing gap, the carbon dioxide gas is exhausted from the opened gap, when the air pressure generated on the inner fan-shaped leaf sheets 20 of the three exhaust ports after the rubber air bag 15 is acted by the external force is smaller than the elastic restoring force of the inner fan-shaped leaf sheet connecting springs 19 of the three exhaust ports, the inner fan-shaped leaf sheets 20 of the three exhaust ports are spliced together again and close the exhaust gap, and the carbon dioxide gas cannot be continuously exhausted. When the discharged carbon dioxide gas passes through the reducing inner cavity 21 of the exhaust port of the safety device, the flowing kinetic energy and speed of the carbon dioxide gas are greatly consumed due to the increased gas flowing path, so that the flowing speed and the formed gas pressure are low when the carbon dioxide gas flows through the reducing inner cavity 21 to reach the three fan-shaped blades 22 outside the exhaust port, the three fan-shaped blades 22 outside the exhaust port which are spliced and sealed are not easy to push open, and the exhaust from the splicing seams of the three fan-shaped blades 22 outside the exhaust port cannot be realized. Even if the gas pressure of the carbon dioxide gas acting on the three fan-shaped blades 22 outside the exhaust port is temporarily larger than the elastic restoring force of the fan-shaped blade connecting springs 23 outside the exhaust port and causes partial discharge of the carbon dioxide gas, when the gas pressure of the carbon dioxide gas is smaller than the elastic restoring force of the fan-shaped blade connecting springs 23 outside the exhaust port, the three fan-shaped blades 22 outside the exhaust port are spliced and closed again and prevent the carbon dioxide gas from being discharged continuously, and finally, most of the carbon dioxide gas is still remained in the rubber air bag 15, so that long-term effective protection for personnel is formed.
