Description

Amphibious high-altitude falling personnel protection device

Technical Field

The invention relates to the technical field of high-altitude operation protection, in particular to an amphibious high-altitude falling personnel protection device.

Background

In the daily production activities of the engineering construction industry, people are prone to high falling accidents caused by lack of safety consciousness of people, unavailable safety measures or high-altitude adventure operation, and finally, people and property are subjected to great loss, and meanwhile, the happiness and the future of innocent practitioners and families are destroyed.

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 protect high falling 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 (CN106730431A, CN106730431B and CN206285358U), 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 quite different and complicated, the high-altitude falling protection devices can play a certain degree of falling protection when high-altitude operation and high-risk personnel have a falling dangerous situation and the personnel are in a falling state, so that the personal casualty rate of the high-falling personnel is reduced, but zero casualty and comprehensive protection of the falling personnel cannot be completely realized, and the various high-altitude falling protection devices also have respective characteristics and application ranges and have different technical short plates and problems, which will be described in detail below.

The high-altitude falling protection device comprises a high-altitude falling protection device (CN106730431A, CN106730431B and CN206285358U), wherein after the high-altitude falling protection device is worn on a high-altitude operation and high-risk personnel through a backpack, when the personnel are in a high-falling dangerous condition and in a falling state, a three-axis acceleration sensor in the 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, after ignition, an igniter and an air generating agent are ignited to form a large amount of gas to inflate a safety airbag, the fully inflated airbag forms a safety airbag, the personal safety of the falling personnel is protected, and falling damage is reduced. But it also has the following technical shortcomings:

the device has more parts and complex structure, can be put into use after being customized and assembled by a professional manufacturer, and has higher manufacturing cost and poorer economy;

when the personnel take place to fall the dangerous situation, the device inflates air bag fast to the personnel wear the back and form huge protection gasbag, and the control box is located air bag's central point and puts, when the posture of falling personnel is face-down back down, air bag can play the protection to the personnel of falling and reduce the injury that falls to minimum, if the posture of falling is face-down back up, air bag can't protect the personnel, personnel and ground direct contact cause the casualties accident, so there are serious leak and potential safety hazard in the protection mechanism of the device. 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;

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 narrower application range and poorer universality;

because the device is carried on the back or the abdomen of the person and contains a large number of parts and heavy dead weight, the device is easy to increase the burden of the person and consume the physical strength and energy of the person during the operation of the person, thereby reducing the working efficiency of the person and having poor social benefit.

Secondly, be a high altitude protection device that falls and working method (CN109224338A) thereof, when the human body that falls appears above the protection network, will fall human body information transmission to control module through human detection module, control module exports control protection network motion module again to start the protection network switch and make and reset through compression spring and drive the protection network installation department and pop out along horizontal guide bar, the protection network also expands along the wall body reentrant corner simultaneously, in order to catch the human body that falls, plays safety protection's effect. But it also has the following technical shortcomings:

firstly, main high-fall protection parts such as a protection net, a protection net mounting part, a protection net movement module, a protection net switch and the like in the device are appointed to be mounted in internal corners of two layers of wall bodies 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 wall bodies of the outer vertical surface of the building; (ii) a

Secondly, the device contains more parts and is complex in structure, a professional manufacturer must be entrusted to customize, produce and transport the parts to the site for installation and debugging, the device can be put into use, the manufacturing and using cost is high, the economy is poor, meanwhile, an 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;

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 three internal corners of the wall body, and protects personal safety, but the opposite surfaces of the internal corners of the wall body are open surfaces and have no horizontal protective measures, so that the falling personnel have the possibility of rolling out of the open surfaces, personal safety accidents are easily caused, the protection mechanism of the device has leak and potential safety hazards, the use risk is high, and comprehensive protection cannot be formed;

and fourthly, because the device and each part are arranged on each floor of the internal corner of the outer wall, the difficulty and the workload of the daily matching maintenance work are high, climbing equipment is needed in the maintenance process, operation and corresponding risks exist, the maintenance cost is high, and the safety risk is high.

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

Detailed Description

Examples

As shown in fig. 1 to 6 and 19 to 25, an amphibious type high fall personnel protection apparatus; comprises a tubular storable rubber airbag 15, a safety device harness 13 arranged in the storable rubber airbag 15, and a gas generator 16 arranged on the outer wall of the storable rubber airbag 15;

when the stowable rubber airbag 15 is not inflated, the stowable rubber airbag 15 is fixed around the user's waist by the safety harness 13;

after the stowable rubber bladder 15 is not inflated, the stowable rubber bladder 15 is expanded into a tubular structure having a length greater than the height of the user, placing the user in the inner cavity of the stowable rubber bladder 15;

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

at least one safety device vent hole 17 is arranged at the opening position of the two ends 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 diameter 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;

the fan-shaped blades 22 on the outer sides of all the air outlets and the fan-shaped blades 20 on the inner sides of all the air outlets are respectively connected with the corresponding port parts of the corresponding air outlet reducing inner cavities 21 of the safety devices and are spliced at the corresponding port positions of the corresponding air outlet reducing inner cavities 21 of the safety devices to form circular sheet structures capable of shielding the corresponding ports;

an air outlet outside fan-shaped leaf connecting spring 23 is arranged between one surface of each air outlet outside fan-shaped leaf 22 facing the inner side of the corresponding air outlet reducing inner cavity 21 of the safety device and the corresponding outward sinking shoulder;

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

The using method and the working mechanism of the invention are as follows:

before the user works, the user wears the safety device on the ground, the foldable rubber air bag 15 which is folded and stored is penetrated into the middle of the body from the feet of the user and is temporarily worn on the waist, and meanwhile, the shoulder belt and the leg belt of the safety device suspender 13 are respectively penetrated through the arm and the legs and then worn between the shoulder and the legs, so that the safety device is firmly worn and closely fitted, and on the basis, the worker can climb and carry out high-altitude work.

When a user accidentally slips to fall or the operation platform suddenly becomes unstable and overturns during aloft 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 rubber air bag from the original high-pressure low-temperature environment in the storage tank to the normal-temperature normal-pressure environment, the carbon dioxide is gasified from the liquid state into carbon dioxide gas after the carbon dioxide is gasified to react, namely the liquid carbon dioxide absorbs the heat in the rubber airbag, when the carbon dioxide is gasified, the volume of the carbon dioxide gas is expanded by about 450 to 640 times, namely, the conversion rate of liquid carbon dioxide to gaseous carbon dioxide is 189-269L/min per minute, and after absorbing a large amount of heat, the temperature in the rubber air bag 15 is reduced to a lower value, and the air bag 15 is prevented from bursting due to overhigh temperature and pressure in the air bag when the rubber air bag is used in hot and high-temperature weather or environment. 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 person and the rubber air bag 15 wrapped by the person land stably, the person can take off the safety device straps 13 in the air bag by himself, the shoulder straps and the leg straps are included, and the person climbs out from the openings at the two ends of the tail of the rubber air bag 15 to escape, so that effective self rescue is realized. 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 personnel and the personnel wrapped by the rubber air bag 15 are in falling contact with the ground or the rubber air bag 15 is pressed or impacted by a heavy object to cause the carbon dioxide gas filled in the rubber air bag 15 to excessively exhaust through the exhaust port 17 and cannot form long-term effective protection for the personnel, 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 fan-shaped leaf sheet 20 at the inner side of the exhaust port in advance and compresses the fan-shaped leaf sheet connecting spring 19 at the inner side of the exhaust port to ensure that the fan-shaped leaf sheets 20 at the inner sides of the three exhaust ports bend outwards and synchronously open the original splicing gap, the carbon dioxide gas is discharged from the opened gap, and when the rubber air bag 15 is acted by external force, the elastic recovery spring which generates the air pressure on the fan-shaped leaf sheets 20 at the inner sides of the three exhaust ports is smaller than the fan-shaped leaf sheets connecting spring 19 at the inner sides of the three exhaust ports When the force is restored, the fan-shaped blades 20 at the inner sides of the three exhaust ports are spliced again to close the exhaust gaps, and carbon dioxide gas cannot be discharged continuously. 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 the flowing speed of the carbon dioxide gas are greatly consumed due to the increase of the gas flowing path, so that the flowing speed of the carbon dioxide gas flowing through the reducing inner cavity 21 to reach the three fan-shaped blades 22 outside the exhaust port is low, the formed gas pressure is low, the three fan-shaped blades 22 outside the exhaust port which are spliced and sealed are not easy to push away, and the carbon dioxide gas cannot be exhausted from the splicing seams of the three fan-shaped blades 22 outside the exhaust port. 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. In addition, the staggered joint arrangement is implemented between the three fan-shaped blades 20 at the inner sides of the exhaust ports and the three fan-shaped blades 22 at the outer sides of the exhaust ports, so that the carbon dioxide gas can be prevented from being directly discharged along the through seams of the fan-shaped blades at the inner sides and the outer sides, the air tightness and the stability are further enhanced, and the rubber air bag 15 has better and more stable performance.
