[0022] The technical solution of the present invention will be further described in detail and non - restrictively below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-6 , the present invention provides a technical solution: a new type of anti - fall device for high - altitude work, including a protective vest body 1. A plurality of spray outlets 11 are evenly arranged on the outer wall of the protective vest body 1. A plurality of installation shells 5 are arranged inside the protective vest body 1. One side of the installation shell 5 is an opening, and the opening is aligned with the spray outlet 11. A flexible airbag 6 is folded and installed inside the installation shell 5. The flexible airbag 6 is connected to the inner wall of the installation shell 5 in a through - connection manner. When it is necessary to expand the flexible airbag 6, it inflates and expands, sprays out and unfolds from the spray outlet 11, and forms a buffer by establishing a barrier between the flexible airbag 6 and the ground, preventing the internal organs of the worker from directly hitting the ground. When not in use, the flexible airbag 6 is folded and stored inside the installation shell 5, reducing the volume and not hindering the normal work of the worker;

[0024] A buffer is formed by establishing a barrier between the flexible airbag 6 and the ground. Once a worker working at high altitude falls, traditional protective measures may not be able to completely prevent the internal organs of the body from being severely impacted. However, after the flexible airbag 6 in this device unfolds, it can effectively reduce this impact force, greatly reducing the risk of serious injuries caused by the direct impact of the internal organs of the worker's body on the ground. And when not in use, the flexible airbag 6 is folded and stored inside the installation shell 5, which greatly reduces the volume of the device and will not hinder the normal work of the worker, facilitating the worker to move freely during high-altitude operations.

[0025] Sodium carbonate powder boxes 7 are evenly installed inside the protective vest body 1. The two ends of the sodium carbonate powder box 7 are correspondingly connected with air pipes 71. One end of the air pipe 71 is connected to the installation shell 5 in a penetrating manner. One end of the sodium carbonate powder box 7 is connected with a one-way valve 72 in a penetrating manner. One end of the one-way valve 72 is connected with a Roots pump housing 73. One end of the Roots pump housing 73 is connected with a liquid pipe 75 in a penetrating manner. One end of the liquid pipe 75 is connected with a hydrochloric acid containing box 4 in a penetrating manner. A Roots pump impeller 74 is installed inside the Roots pump housing 73, and the Roots pump impeller 74 is torque-connected to an external motor. By starting the Roots pump impeller 74, the liquid is driven from the hydrochloric acid containing box 4 through the liquid pipe 75 and pumped into the Roots pump housing 73, and is pumped to the one-way valve 72, so that the hydrochloric acid liquid enters the sodium carbonate powder box 7 and reacts violently with the internal sodium carbonate to generate a large amount of carbon dioxide. The gas will enter the air pipe 71 and then enter the installation shell 5, and the pressure of the gas pushes the flexible airbag 6 to expand, giving the flexible airbag 6 the power to expand.

[0026] When the Roots pump impeller 74 is started, it can drive the liquid from the hydrochloric acid containing box 4 through the liquid pipe 75 and pump it into the Roots pump housing 73, and further pump it to the one-way valve 72, so that the hydrochloric acid liquid enters the sodium carbonate powder box 7. Hydrochloric acid and sodium carbonate will react violently to generate a large amount of carbon dioxide gas. This way of generating gas through chemical reaction can quickly provide inflation power for the flexible airbag 6. Compared with other traditional inflation methods, such as relying solely on external air sources or manual inflation, etc., this method is more automated, fast and reliable. Once a worker falls, it can quickly provide guarantee for the inflation and unfolding of the flexible airbag 6.

[0027] An acceleration sensor and a controller are installed inside the protective vest body 1. The acceleration sensor is electrically connected to the controller, and the controller is electrically connected to the external motor. When the worker accidentally falls, the acceleration sensor senses that it is in a free fall state at this time, sends a signal to the controller, controls the external motor to rotate, and drives the Roots pump impeller 74 to rotate.

[0028] The acceleration sensor can acutely sense that it is in a free - fall state at this time and quickly send a signal to the controller. After receiving the signal, the controller controls the external motor to rotate, thereby driving the rotation of the roots pump vane 74. The beneficial effect of this automatic sensing and control mechanism is that it can promptly respond to the emergency of a worker's fall, start the working process of the entire protection device within an extremely short time, without the need for manual operation by the worker or relying on other complex triggering mechanisms, greatly improving the emergency response speed and reliability of the protection device.

[0029] The outer wall of the flexible airbag 6 is provided with air leakage holes 62. The inner wall of the air leakage hole 62 is fitted with a plastic film 61. The inner wall of the air leakage hole 62 is installed with a fixing block 65. One side of the fixing block 65 is correspondingly connected with an elastic band 64. The two inner walls of the air leakage hole 62 are correspondingly and movably installed with movable opening - closing parts 63. One side of the movable opening - closing part 63 is connected to the elastic band 64. When the flexible airbag 6 is subjected to a strong impact, in order to prevent it from exploding and injuring the worker, first, the huge pressure will pass through the plastic film 61, causing it to tear, and the air can be ejected from the air leakage hole 62 for a certain degree of air release to prevent explosion. The gas will push the movable opening - closing part 63 to expand. Due to the pulling effect of the elastic band 64, the movable opening - closing part 63 will not expand excessively, enabling the gas to leak slowly;

[0030] First, the huge pressure will pass through the plastic film 61, causing it to tear, and the air can be ejected from the air leakage hole 62 for a certain degree of air release. This process can prevent the flexible airbag 6 from exploding due to excessive internal pressure, thereby avoiding secondary injuries to the worker caused by the fragments or strong impact force generated by the explosion. At the same time, the gas will push the movable opening - closing part 63 to expand. Due to the pulling effect of the elastic band 64, the movable opening - closing part 63 will not expand excessively, enabling the gas to leak slowly. This slow air - release method allows the flexible airbag 6 to maintain a certain pressure and shape during the buffering process, continuously playing a buffering role instead of losing the buffering ability instantly.

[0031] The top of the protective vest body 1 is installed with a loading and unloading buckle 2. One end of the loading and unloading buckle 2 is provided with a shoulder strap 3. Through the loading and unloading buckle 2 and the shoulder strap 3, the protective vest body 1 can be worn on the worker's body;

[0032] One end of the shoulder strap 3 is movably hinged with a connecting seat 28. One end of the connecting seat 28 is connected with a clamping part 27. The two sides of the clamping part 27 are correspondingly provided with embedded grooves 271. The inner wall of the embedded groove 271 is installed with a spring 25. One end of the spring 25 is installed with a button 241. The two sides of the loading and unloading buckle 2 are correspondingly provided with through - holes 24. The button 241 passes through the through - hole 24. When disassembly is required, just press the button 241, causing the spring 25 to be compressed. At this time, the clamping part 27 can be separated from the loading and unloading buckle 2, so that the shoulder strap 3 is separated from the loading and unloading buckle 2, facilitating smooth disassembly and assembly;

[0033] One side of the strap 3 is rotatably provided with a movable arm 31. One end of the movable arm 31 is movably connected to a movable column 26. The middle part of the clamping portion 27 is a hollow structure. One end of the movable column 26 passes through the clamping portion 27. One end of the movable column 26 is connected to a second screwing buckle 23. A fixed column 21 is installed on the inner wall of the loading and unloading buckle 2. One end of the fixed column 21 is connected to a first screwing buckle 22. The first screwing buckle 22 and the second screwing buckle 23 are a matching structure. By mutually buckling the first screwing buckle 22 and the second screwing buckle 23, the connecting seat 28 and the loading and unloading buckle 2 are mutually connected, so that the strap 3 can be fixed on the worker's body;

[0034] It provides a simple and convenient disassembly method. Workers can easily disassemble the protective vest without using complex tools, which is convenient for maintaining, replacing or storing the protective vest.

[0035] One end of the first screwing buckle 22 is provided with an arc-shaped groove 221. The inner wall of the arc-shaped groove 221 extends inwards to be provided with an inner arc-shaped block 222. One end of the second screwing buckle 23 is provided with an extension edge 232. The outer wall of the extension edge 232 is provided with an outer arc-shaped block 231. In the tightened state, the outer arc-shaped block 231 and the inner arc-shaped block 222 are mutually buckled to prevent the first screwing buckle 22 and the second screwing buckle 23 from separating. When rotated 180 degrees, the outer arc-shaped block 231 rotates to the arc-shaped groove 221, and the two can be separated smoothly.

[0036] When the worker accidentally falls, the acceleration sensor reacts to the rapid descent at this time, controls the hydrochloric acid to be pumped into the sodium carbonate powder box 7, and a large amount of carbon dioxide is generated by the reaction of sodium carbonate powder and hydrochloric acid, so that each airbag instantaneously expands, and an airbag is formed to wrap around the worker's body, and an airbag buffer is formed before the worker's body contacts the ground, protecting the internal organs of the worker's body from being severely impacted on the ground, achieving the effect of fall prevention.

[0037] It can firmly fix the strap 3 on the worker. When the worker is working at height, it will not loosen or fall off easily, ensuring the stability of the protective vest during the operation. At the same time, one end of the first screwing buckle 22 is provided with an arc-shaped groove 221. The inner wall of the arc-shaped groove 221 extends inwards to be provided with an inner arc-shaped block 222. One end of the second screwing buckle 23 is provided with an extension edge 232. The outer wall of the extension edge 232 is provided with an outer arc-shaped block 231. In the tightened state, the outer arc-shaped block 231 and the inner arc-shaped block 222 are mutually buckled to prevent the first screwing buckle 22 and the second screwing buckle 23 from separating. When rotated 180 degrees, the outer arc-shaped block 231 rotates to the arc-shaped groove 221, and the two can be separated smoothly. This design not only ensures the firmness of the connection but also facilitates quickly separating the two when disassembly is needed.
