Description

Technical Field

[0001] This invention belongs to the field of fall prevention technology in building construction, specifically, it relates to a fall prevention device for high-altitude operations in building construction. Background Technology

[0002] During construction, many construction sites install fall protection nets for safety. Current fall protection nets mainly consist of a frame and a safety net installed within the frame. When a worker or object accidentally falls from a height, the fall protection net can use its elasticity to cushion the falling object and reduce damage. An existing patent (application number: CN201810732733.2) discloses a fall protection net to improve construction safety, including a protective net and a fixing device for securing the protective net to a steel structure. The fixing device includes multiple mounting blocks, each with fasteners that secure the mounting block to the steel structure. Several rope hooks capable of hooking the protective net are arrayed along the length of the mounting block on its front side.

[0003] The aforementioned fall protection equipment provides fall protection by using a fall protection net made of special materials. However, in actual use, since heavy objects often move downwards from a height, the kinetic energy generated by the falling object is absorbed by the protective net and the rollers that wind the protective net in a very short time, resulting in excessive local stress. This may cause the protective net to be subjected to excessive impact force and break directly.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fall protection device for high-altitude operations in building construction, so as to improve the fall protection effect.

[0006] To solve the above-mentioned technical problems, the present invention provides a high-altitude operation fall prevention device for building construction, comprising: a mounting base; a mounting cylinder connected to the mounting base for storing a protective net; a protective net winding roller rotatably connected inside the mounting cylinder for winding the protective net; two rotating shafts connected to both ends of the protective net winding roller and rotating synchronously with the protective net winding roller; auxiliary mechanisms for preventing the protective net from falling are provided on both sides inside the mounting cylinder; triggering components for triggering the auxiliary mechanisms are also provided on both sides of the mounting cylinder; wherein, the auxiliary mechanisms include two progressive buffering components disposed inside the mounting cylinder and located on the left and right sides of the protective net winding roller; the progressive buffering components are used to progressively buffer the impact force of the protective net; and an impact-resistant component is provided on one side of the progressive buffering components to further buffer the impact force.

[0007] Furthermore, the gradual buffer assembly includes a transmission ring rotatably connected inside the mounting cylinder. Two symmetrical irregularly shaped abutment blocks are connected inside the transmission ring. A compression spring is connected inside the mounting cylinder. The other end of the compression spring is connected to a limit clamp. When the irregularly shaped abutment block rotates to a certain position with the transmission ring, it abuts against the limit clamp and drives the limit clamp to move towards the central axis of the rotating shaft.

[0008] Furthermore, the triggering component includes a mounting plate connected to a rotating shaft and rotatably connected to a mounting cylinder. The mounting plate rotates synchronously with the rotating shaft. A connecting plate is connected to the mounting plate, and two symmetrical locking strips are rotatably connected to the connecting plate. A connecting post is connected to the mounting plate, and the locking strips are rotatably connected to the connecting post. A fixing block is connected to the mounting plate, and a fixing spring is connected to one side of the fixing block. The other end of the fixing spring is connected to the locking strips. A transmission disc is rotatably connected inside the mounting cylinder, and multiple locking blocks are connected to the transmission disc. The multiple locking blocks are distributed in a circular array with equal spacing around the central axis of the mounting disc. When the mounting disc rotates to a certain speed, the locking strips rotate and engage with the locking blocks. A connecting rod is connected to one side of the transmission disc, and the transmission disc is connected to the transmission ring through the connecting rod.

[0009] Furthermore, each of the card blocks is connected to a storage battery, and an electromagnet electrically connected to the storage battery is connected to the card block. An abutment switch is connected to the outer surface of the card block.

[0010] Furthermore, the impact-resistant assembly includes a mounting base connected inside the mounting cylinder, a rotating plate rotatably connected to the mounting base, and the mounting base and the rotating plate working together to form a lever mechanism. A first transmission plate is connected to one side of the limiting clamp, and one end of the first transmission plate is rotatably connected to the rotating plate. A buffer airbag is connected inside the mounting cylinder. When the first transmission plate drives one end of the rotating plate to tilt up, the other end of the rotating plate squeezes the buffer airbag. A sealing frame is connected to one side of the buffer airbag through a short pipe. A damper is connected inside the sealing frame, and a buffer spring is sleeved on the damper. A sliding plate is slidably connected inside the sealing frame, and the other ends of the damper and the buffer spring are connected to the sliding plate. The sliding plate is used to squeeze the damper and the buffer spring when the gas inside the sealing frame increases.

[0011] Furthermore, the sealed frame is also equipped with a fall warning component, which includes a first pulley and a second pulley connected within the sealed frame. A connecting rope is attached to both the first pulley and the second pulley. One end of the connecting rope is connected to the slide plate, and the other end is connected to an impact block. A connecting spring is connected within the sealed frame, and the other end of the connecting spring is connected to a warning switch. When the impact block moves to a certain position, it abuts against the warning switch. An alarm switch is also connected within the sealed frame, and when the slide plate moves to a certain position, it abuts against the alarm switch.

[0012] Furthermore, one side of the mounting cylinder is also provided with a shaking component for cleaning impurities on the protective net. The shaking component includes a mounting plate connected to the mounting base. A connecting plate is rotatably connected to the mounting plate. A fixed frame is connected to the connecting plate. A second transmission plate is rotatably mounted on the fixed frame. The other end of the second transmission plate is rotatably connected to the connecting frame. A servo motor that drives the connecting plate to rotate is connected to one side of the mounting plate. A telescopic rack is slidably connected inside the connecting frame. Both sides of the telescopic rack are meshed with transmission gears. A clamping block is connected to the transmission gear. When the clamping block rotates with the transmission gear to a certain position, it clamps the protective net. An electric telescopic rod that drives the telescopic rack to move is connected to one side of the connecting frame.

[0013] Furthermore, the fixed frame is also provided with an adjustment component for adjusting the shaking amplitude of the clamping block. The adjustment component includes a slider slidably connected in the fixed frame. A limit rod is connected to the slider. The second transmission plate is rotatably connected to the limit rod. A limit rod for limiting the position of the slider is slidably connected to the slider. A force plate is connected to one end of the limit rod. A mounting spring is sleeved on the limit rod. The fixed frame has multiple limit grooves distributed in a linear array at equal intervals. The limit grooves are adapted to the limit rods.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0015] 1. In this invention, when a heavy object falls onto the protective net, the irregularly shaped contact block rotates synchronously with the transmission ring. When the irregularly shaped contact block rotates to a certain position, it can abut against the limiting clamping block and drive the limiting clamping block to gradually clamp and fix the rotating shaft, thereby avoiding the situation where the protective net breaks due to excessive clamping force. At the same time, when the limiting clamping block clamps the rotating shaft, it will drive one end of the rotating plate to tilt up through the first transmission plate. At this time, the other end of the rotating plate moves downward and squeezes the buffer airbag. Subsequently, the gas in the buffer airbag is compressed into the sealing frame. When the pressure in the sealing frame increases, the sliding plate can move downward and press the damper and buffer spring for further buffering. This setting allows the protective net to gradually buffer the heavy object, avoiding the situation where the protective net breaks due to the instantaneous impact force, and construction workers or building materials fall directly from the protective net, further improving the fall prevention effect.

[0016] 2. In this invention, when a heavy object falls onto the protective net, the rotating shaft begins to rotate rapidly due to the influence of the heavy object. At the same time, the mounting plate rotates with the rotating shaft. When its rotation speed reaches a certain speed, the clamping strip is affected by the centrifugal force of the mounting plate, causing its end to extend out of the mounting plate and engage with the clamping block, thereby driving the clamping block to rotate. During the rotation of the clamping block, the transmission ring can be driven to move synchronously through the connecting rod, thereby driving the components inside the gradual buffer assembly to gradually decelerate the protective net. This setting ensures that the gradual buffer assembly can only be activated when encountering a heavy object, avoiding unnecessary mechanical movement of the gradual buffer assembly and extending the service life of the components inside the gradual buffer assembly.

[0017] 3. In this invention, the electric telescopic rod is activated to drive the telescopic rack to slide. During the sliding process, the telescopic rack drives two transmission gears to rotate. The clamping blocks connected to the transmission gears can then move relative to each other and clamp the protective net. After clamping, the servo motor is activated to drive the connecting plate to rotate. Subsequently, the second transmission plate mounted on the connecting plate can drive the connecting frame to swing up and down. During the swinging process, the protective net clamped by the clamping blocks can make a wave-like displacement, thereby shaking off small construction debris that falls on it. At the same time, during the wave-like movement of the protective net, the tension of the protective net can also be adjusted within a certain range to ensure the subsequent protective effect.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] During construction, many construction sites install fall protection nets for safety. Current fall protection nets mainly consist of a frame and the netting installed within it. When workers or objects accidentally fall from heights, the netting uses its elasticity to cushion the falling object and reduce damage. While the netting, made of special materials, provides fall protection, in actual use, heavy objects often fall from heights. The kinetic energy generated by the falling object is absorbed by the netting and the rollers that wind around it in a very short time, causing excessive local stress. This can lead to the netting being subjected to excessive impact and breaking directly.

[0048] Please refer to Figure 1-14 As shown, the present invention provides a high-altitude operation fall prevention device for building construction, comprising: a mounting base 1, a mounting cylinder 2 connected to the mounting base 1 for storing a protective net, a protective net winding roller 3 rotatably connected inside the mounting cylinder 2 for winding the protective net, two rotating shafts 4 connected to both ends of the protective net winding roller 3 and rotating synchronously with the protective net winding roller 3, auxiliary mechanisms for preventing fall of the protective net are provided on both sides inside the mounting cylinder 2, and triggering components 5 for triggering the auxiliary mechanisms are also provided on both sides of the mounting cylinder 2.

[0049] The auxiliary mechanism includes two progressive buffer components 9 installed inside the mounting cylinder 2 and located on the left and right sides of the protective net winding roller 3. The progressive buffer components 9 are used to progressively buffer the impact force of the protective net. An anti-impact component 10 is provided on one side of the progressive buffer components 9 to further buffer the impact force.

[0050] In this invention, it is considered that in the process of high-altitude fall protection, protective nets are often used. However, due to the large instantaneous impact force, the protective net may break. Therefore, the step-buffering component 9 is set to gradually buffer the protective net when it is impacted, so that the instantaneous impact force is gradually dispersed and the risk of the protective net breaking is reduced.

[0051] Furthermore, considering that the protective net may have limited protective effect, the impact-resistant component 10 can buffer synchronously with the buffer component 9 during the gradual buffering process, thereby further improving the buffering and fall prevention effect of the protective net.

[0052] Meanwhile, during daily construction, some small pieces of construction debris may fall onto the protective netting. The protective netting alone can be used to prevent falls without the need for the gradual buffer component 9 and the impact-resistant component 10. Therefore, the trigger component 5 is designed so that the gradual buffer component 9 and the impact-resistant component 10 will be triggered to provide further protection only when a heavy object or worker falls, i.e. when the instantaneous impact force on the protective netting is too large.

[0053] Based on the above, the specific structure needs to be disclosed in detail.

[0054] The first requirement is to ensure that when a heavy object falls onto the safety net, the net gradually cushions the impact, reducing the instantaneous force of the falling object. Figure 4 and Figure 5 A transmission ring 901 is rotatably installed inside the mounting cylinder 2. Two symmetrical irregularly shaped contact blocks 902 are connected inside the transmission ring 901. A compression spring 904 is connected inside the mounting cylinder 2, and the other end of the compression spring 904 is connected to a limit clamp 903. When the irregularly shaped contact block 902 rotates to a certain position with the transmission ring 901, it abuts against the limit clamp 903, driving the limit clamp 903 to move towards the central axis of the rotating shaft 4. The irregularly shaped contact block 902 rotates synchronously with the transmission ring 901. When the irregularly shaped contact block 902 rotates to a certain position, it abuts against the limit clamp 903, causing the limit clamp 903 to clamp the rotating shaft 4. Please continue to refer to... Figure 5 To ensure the gradual buffering effect of the gradual buffering component 9, the irregularly shaped abutment block 902 is designed with a special shape. Its overall outer surface movement consists of an initial upward slope, followed by a slight downward slope, and finally reaching the highest upward slope. Specifically, during the contact between the irregularly shaped abutment block 902 and the limiting clamp 903, the abutment block 902 first contacts the limiting clamp 903, causing the limiting clamp 903 to clamp and fix the rotating shaft 4, thus providing initial buffering of the impact force – this is the slope section. Subsequently, when the irregularly shaped abutment block 902 moves to the downward slope section, the limiting clamp 903 is compressed by the spring 9. The elastic force of 04 makes a return motion, avoiding the situation where the limiting clamp 903 is directly fixed to the rotating shaft 4, which would cause the protective net to break. At the same time, during the process of the irregularly shaped contact block 902 moving to the downhill section, the limiting clamp 903 still maintains a certain contact with the rotating shaft 4, but the tightness of the contact is reduced. At the same time, the downhill section allows the protective net to continue to maintain a certain inertia, making its buffering more stable. When the irregularly shaped contact block 902 moves to the top of the slope, the irregularly shaped contact block 902 can completely abut against the limiting clamp 903, so that the limiting clamp 903 is completely clamped on the rotating shaft 4, limiting the continued fall of the protective net.

[0055] Furthermore, to further ensure the contact effect of the irregularly shaped contact block 902 against the limiting clamping block 903, and to make the movement of the limiting clamping block 903 more stable when the irregularly shaped contact block 902 contacts the limiting clamping block 903, please refer to [reference needed]. Figure 3 Two irregularly shaped abutment blocks 902 are provided on the left and right sides of a limiting clamping block 903. In order to set two irregularly shaped abutment blocks 902 on each limiting clamping block 903, the number of transmission rings 901 should also be set to two. In order to avoid motion conflict between the two transmission rings 901 and the compression spring 904, the material of the two transmission rings 901 can be set to permanent magnets, so that the two transmission rings 901 can be driven by magnetic force. In order to avoid the transmission rings 901 affecting the clamping effect of the limiting clamping block 903, the material of the limiting clamping block 903 is set to copper. At the same time, the material of the limiting clamping block 903 can also be aluminum, nickel alloy, aluminum alloy, titanium alloy, etc., as long as it is not affected by the magnetic force of the transmission rings 901.

[0056] Please continue to refer to this. Figure 2 , Figure 3 and Figure 11 During the protective netting operation, some small pieces of construction debris or building materials may fall onto the netting. At this point, the netting itself is sufficient to prevent falls. However, to avoid unnecessary mechanical action and extend the lifespan of the gradual buffer component 9, the trigger component 5 is configured to only activate the gradual buffer component 9 when a heavy object falls onto the netting. Please refer to [reference needed]. Figure 11 The trigger assembly 5 includes a mounting plate 501 connected to the rotating shaft 4 and rotatably connected to the mounting cylinder 2. The mounting plate 501 rotates synchronously with the rotating shaft 4. A connecting plate 502 is connected to the mounting plate 501, and two symmetrical retaining strips 503 are rotatably connected to the connecting plate 502. A connecting post 504 is connected to the mounting plate 501, and the retaining strips 503 are rotatably connected to the connecting post 504. A fixing block 505 is connected to the mounting plate 501, and a fixing spring 506 is connected to one side of the fixing block 505. The other end of the fixing spring 506 is connected to the retaining strips 503.

[0057] A transmission disc 507 is rotatably connected inside the mounting cylinder 2. Multiple locking blocks 508 are connected to the transmission disc 507. The multiple locking blocks 508 are distributed in a circular array with equal spacing around the central axis of the mounting disc 501. When the mounting disc 501 rotates to a certain speed, the locking strip 503 rotates and engages with the locking blocks 508. A connecting rod 14 is connected to one side of the transmission disc 507. The transmission disc 507 is connected to the transmission ring 901 through the connecting rod 14.

[0058] When a heavy object falls onto the protective net, the rotating shaft 4 begins to rotate rapidly due to the influence of the heavy object. At the same time, the mounting plate 501 rotates along with the rotating shaft 4. When its rotation speed reaches a certain speed, the clamping strip 503 is affected by the centrifugal force of the mounting plate 501, causing its end to extend out of the mounting plate 501 and engage with the clamping block 508, thereby driving the clamping block 508 to rotate. During the rotation, the clamping block 508 can drive the transmission ring 901 to move synchronously through the connecting rod 14, thereby driving the components inside the gradual buffer assembly 9 to gradually decelerate the protective net.

[0059] For further information, please refer to the following: Figure 11 To improve the fixing effect of the card block 508 on the card strip 503, each card block 508 is connected to a battery 6. An electromagnet 7 electrically connected to the battery 6 is connected inside the card block 508. A contact switch 8 is connected to the outer surface of the card block 508. When the card strip 503 contacts the contact switch 8, the battery 6 is energized and the electromagnet 7 becomes magnetic. When the card strip 503 contacts the card block 508, the battery 6 is turned on, so that the electromagnet 7 is energized and becomes magnetic. Then, the magnetic force can be used to make the card strip 503 adhere to the card block 508.

[0060] Please continue to refer to this. Figure 6 , Figure 7 and Figure 12 To further enhance the buffering effect of the protective net, an impact-resistant component 10 is designed. The impact-resistant component 10 includes a mounting base 1001 connected within the mounting cylinder 2. A rotating plate 1003 is rotatably connected to the mounting base 1001. The mounting base 1001 and the rotating plate 1003 cooperate to form a lever mechanism. A first transmission plate 1002 is connected to one side of a limiting clamp 903. One end of the first transmission plate 1002 is rotatably connected to the rotating plate 1003. A buffer airbag 1004 is connected inside the mounting cylinder 2. The first transmission plate 1002 drives the rotating plate 1003... When the end is tilted up, the other end of the rotating plate 1003 squeezes the buffer airbag 1004. One side of the buffer airbag 1004 is connected to a sealing frame 1005 through a short pipe. A damper 1007 is connected inside the sealing frame 1005. A buffer spring 1008 is sleeved on the damper 1007. A sliding plate 1006 is slidably connected inside the sealing frame 1005. The other ends of the damper 1007 and the buffer spring 1008 are connected to the sliding plate 1006. The sliding plate 1006 is used to squeeze the damper 1007 and the buffer spring 1008 when the gas inside the sealing frame 1005 increases.

[0061] When the limiting clamp 903 clamps the rotating shaft 4, it will cause one end of the rotating plate 1003 to tilt up through the first transmission plate 1002. At this time, the other end of the rotating plate 1003 moves down and squeezes the buffer airbag 1004. Then the gas in the buffer airbag 1004 is compressed into the sealing frame 1005. When the pressure in the sealing frame 1005 increases, the slide plate 1006 can move down and press the damper 1007 and the buffer spring 1008 for further buffering.

[0062] Please continue to refer to this. Figure 12 When heavy objects or construction debris fall onto the protective netting, a warning component 11 is designed to facilitate timely notification and rescue or cleanup by management personnel. The warning component 11 includes a first pulley 1101 and a second pulley 1102 connected within a sealing frame 1005. A connecting rope 1103 is attached to both the first pulley 1101 and the second pulley 1102. One end of the connecting rope 1103 is connected to a sliding plate 1006, and the other end is connected to an impact block 1104. A connecting spring is connected within the sealing frame 1005, and the other end of the connecting spring is connected to a warning switch 1105. When the impact block 1104 moves to a certain position, it abuts against the warning switch 1105. An alarm switch 1106 is connected within the sealing frame 1005. When the sliding plate 1006 moves to a certain position, it abuts against the alarm switch 1106.

[0063] When construction debris falls onto the protective netting, it causes the sliding plate 1006 to slide downwards. At this time, the connecting rope 1103, affected by the sliding plate 1006, can cause the impact block 1104 to rise. When the falling construction debris is relatively light, the impact block 1104 rises only slightly and will only come into contact with the warning switch 1105, causing the warning switch 1105 to sound an alarm, allowing management personnel to clean up the construction debris on the protective netting in a timely manner. However, when the falling construction debris is relatively heavy, the sliding plate 1006 descends more significantly and comes into contact with the alarm switch 1106, allowing management personnel to be aware that a heavy object has fallen onto the protective netting in a timely manner. If the object that fell is a construction worker, timely rescue can be carried out.

[0064] Please continue to refer to this. Figure 1 , Figure 8 , Figure 9 and Figure 10When small pieces of construction debris fall onto the protective netting, or when the netting sags slightly due to its own weight after being suspended for a long time, construction workers may find it inconvenient to clean up the debris or adjust the tension of the netting due to limited installation space. Therefore, a shaking component 12 is designed to facilitate the cleaning of small debris and simple adjustment of the netting's tension. The shaking component 12 includes components connected to the mounting base 1. Mounting plate 1201, a connecting plate 1202 is rotatably connected to the mounting plate 1201, a fixing frame 1203 is connected to the connecting plate 1202, a second transmission plate 1204 is rotatably mounted on the fixing frame 1203, a connecting frame 1205 is rotatably connected to the other end of the second transmission plate 1204, a servo motor 1211 for driving the connecting plate 1202 to rotate is connected to one side of the mounting plate 1201, a guide block 1210 is connected to one side of the connecting frame 1205, and the guide block 1210 is slidably connected to the mounting plate 1201.

[0065] A telescopic rack 1206 is slidably connected inside the connecting frame 1205. Both sides of the telescopic rack 1206 are meshed with transmission gears 1207. A clamping block 1208 is connected to the transmission gear 1207. When the clamping block 1208 rotates to a certain position with the transmission gear 1207, it clamps the protective net. An electric telescopic rod 1209 that drives the telescopic rack 1206 to move is connected to one side of the connecting frame 1205.

[0066] When cleaning is required, the electric telescopic rod 1209 is first activated to drive the telescopic rack 1206 to slide. During the sliding process, the telescopic rack 1206 drives the two transmission gears 1207 to rotate. The clamping blocks 1208 connected to the transmission gears 1207 can then move relative to each other and clamp the protective net. After clamping, the servo motor 1211 is activated to drive the connecting plate 1202 to rotate. Subsequently, the second transmission plate 1204, which is rotated on the connecting plate 1202, drives the connecting frame 1205 to swing up and down. During the swinging process, the protective net clamped by the clamping block 1208 can make a wave-like displacement, thereby shaking off small construction debris that has fallen on it. At the same time, during the wave-like movement of the protective net, the tension of the protective net can also be adjusted within a certain range to ensure the subsequent protective effect. The guide block 1210 is set to guide the sliding of the connecting frame 1205.

[0067] Please continue to refer to this. Figure 9 and Figure 13Sometimes, construction debris falling onto the protective netting is relatively large. In this case, the shaking amplitude can be increased to shake the debris off. The adjustable component 13 allows for easy adjustment of the shaking amplitude. The fixed frame 1203 also has an adjustable component 13 for adjusting the shaking amplitude of the clamping block 1208. The adjustable component 13 includes a slider 1301 slidably connected within the fixed frame 1203. A limit rod 1302 is connected to the slider 1301. The second transmission plate 1204 is rotatably connected to the limit rod 1302. A limit rod that limits the position of the slider 1301 is slidably connected to the slider 1301. 1302, one end of the limiting rod 1302 is connected to a force plate 1303, and a mounting spring 1304 is sleeved on the limiting rod 1302. The fixing frame 1203 has multiple limiting grooves 1305 distributed in a linear array at equal intervals. The limiting grooves 1305 are adapted to the limiting rod 1302. Pulling the force plate 1303 makes the limiting rod 1302 no longer plugged into the limiting grooves 1305. Then, sliding the slider 1301 and adjusting the distance between the slider 1301 and the center of the connecting plate 1202 can adjust the amplitude of the shaking. This setting allows the shaking component 12 to adapt to various situations during use.

[0068] Furthermore, to facilitate unified control of the aforementioned equipment, an Internet of Things (IoT) approach can be used to connect the electronic devices to a host system and a backend system. The operation of the electronic devices, as well as the working status and alarm status of the fall arrestor, can be monitored via a display. This allows for rapid rescue efforts in the event of a sudden fall. To further enhance management efficiency, a mobile query platform can be set up, allowing supervisors to check the equipment's operational status at any time. To reduce operating and wiring costs, a solar panel with a battery can be connected to the equipment for extended power supply, effectively solving the mobile power supply problem. The solar panel collects solar energy and stores it in the battery for continuous use. To facilitate timely detection and rescue by personnel near the equipment in the event of a fall, two indicator lights can be connected to the mounting base 1. One indicator light shows the equipment is operating normally, while the other is activated in the event of a fall. For easy differentiation, the operating indicator light can be set to green, and the indicator light illuminating in the event of a fall can be set to red. A green light indicates normal operation, while a red light illuminates in the event of a fall.

[0069] Working principle: When a heavy object falls onto the protective net:

[0070] When a heavy object falls onto the protective net, the rotating shaft 4 starts to rotate rapidly due to the influence of the heavy object. At the same time, the mounting plate 501 rotates with the rotating shaft 4. When its rotation speed reaches a certain speed, the clamping strip 503 is affected by the centrifugal force of the mounting plate 501, which causes its end to extend out of the mounting plate 501 and engage with the clamping block 508, thereby driving the clamping block 508 to rotate. During the rotation, the clamping block 508 can drive the transmission ring 901 to move synchronously through the connecting rod 14, thereby driving the components inside the gradual buffer assembly 9 to gradually decelerate the protective net.

[0071] The irregularly shaped contact block 902 rotates synchronously with the transmission ring 901. When the irregularly shaped contact block 902 rotates to a certain position, it can abut against the limiting clamp 903 and drive the limiting clamp 903 to gradually clamp and fix the rotating shaft 4, thereby avoiding the situation where the protective net breaks due to excessive clamping force.

[0072] At the same time, when the limiting clamp 903 clamps the rotating shaft 4, it will drive one end of the rotating plate 1003 to tilt up through the first transmission plate 1002. At this time, the other end of the rotating plate 1003 moves down and squeezes the buffer airbag 1004. Then the gas in the buffer airbag 1004 is compressed into the sealing frame 1005. When the pressure in the sealing frame 1005 increases, the slide plate 1006 can move down and press the damper 1007 and the buffer spring 1008 for further buffering.

[0073] When construction waste falls onto the protective netting, it causes the sliding plate 1006 to slide downwards. At this time, the connecting rope 1103, affected by the sliding plate 1006, can cause the impact block 1104 to rise. When the falling construction waste is relatively light, the impact block 1104 rises only slightly and will only come into contact with the warning switch 1105, causing the warning switch 1105 to sound an alarm, allowing management personnel to clean up the construction waste on the protective netting in time. When the falling construction waste is relatively heavy, the sliding plate 1006 descends more significantly and comes into contact with the alarm switch 1106, allowing management personnel to be aware that a heavy object has fallen onto the protective netting in time. If the object is a construction worker, timely rescue can be carried out.

[0074] When it is necessary to remove small pieces of construction debris that have fallen onto the protective netting:

[0075] The electric telescopic rod 1209 is activated, causing the telescopic rack 1206 to slide. During the sliding process, the telescopic rack 1206 drives the two transmission gears 1207 to rotate. The clamping blocks 1208 connected to the transmission gears 1207 can then move relative to each other and clamp the protective net. After clamping, the servo motor 1211 is activated, causing the connecting plate 1202 to rotate. Subsequently, the second transmission plate 1204, which is rotated on the connecting plate 1202, can drive the connecting frame 1205 to swing up and down. During the swinging process, the protective net clamped by the clamping block 1208 can make a wave-like displacement, thereby shaking off small construction debris that falls on it. At the same time, during the wave-like movement of the protective net, the tension of the protective net can also be adjusted within a certain range to ensure the subsequent protective effect.
