Description

Technical Field

[0001] This invention relates to a safety rope attachment device for distributed photovoltaic construction, belonging to the field of photovoltaic installation technology. Background Technology

[0002] Distributed photovoltaic power generation systems are typically installed on the rooftops of industrial plants, commercial buildings, and residential buildings. Their installation and maintenance are typical high-altitude operations. According to safety regulations, workers must attach safety ropes to reliable anchor points.

[0003] Currently, the safety rope attachment devices used at distributed photovoltaic construction sites are mostly purely mechanical structures, such as hanging rings or anchor points fixed with clamps. These existing devices have the following shortcomings in practical use: 1. Lack of status awareness: The attachment point itself is only a passive load-bearing structure and cannot sense whether it is being attached, let alone identify whether a critical fall load event has occurred.

[0004] 2. Lack of alarm mechanism: In the event of a fall from height, if the worker is unable to call for help or is in a blind spot, the accident is difficult to detect in time, and the "golden time" for emergency rescue is easily missed.

[0005] Therefore, existing safety rope attachment devices can only provide physical anchoring and cannot actively issue alarms when accidents occur, making it difficult to meet the increasingly demanding needs of intelligent construction safety management. Therefore, improvements are urgently needed. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this invention designs a distributed photovoltaic construction safety rope attachment point device, which not only provides a firm physical attachment point, but also senses fall events and automatically triggers an alarm, transforming passive post-event rescue into active alarm and immediate response during the event, thereby significantly improving the safety of working at heights.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A safety rope hanging point device for distributed photovoltaic construction includes a bearing plate, a hanging clamping mechanism installed at the top of the bearing plate, a load-bearing sensing module provided at the bottom of the bearing plate, a hanging rope connected to the bottom of the load-bearing sensing module, and a hanging ring fixedly connected to the bottom of the hanging rope. The load sensing module includes a housing, inside which are a tension sensor for collecting the tension of the suspension rope, a signal processing circuit board with a pre-stored force value judgment algorithm, and a triaxial accelerometer integrated on the signal processing circuit board for real-time collection of vibration acceleration and angle change data of the signal processing circuit board. Both the triaxial accelerometer and the tension sensor are electrically connected to the signal processing circuit board. An alarm module is also provided at the top of the support plate, and the alarm module is electrically connected to the signal processing circuit board.

[0008] Furthermore, a mounting block is fixedly installed on the top of the bearing plate, and the mounting clamping mechanism includes an arc-shaped groove provided on the top of the mounting block and an arc-shaped cover plate covering the top of the arc-shaped groove; Both sides of the arc-shaped groove are integrally provided with an extension plate 1 extending outward, and both sides of the arc-shaped cover plate are integrally provided with an extension plate 2 extending outward. The extension plate 1 and the extension plate 2 are detachably connected by a number of locking bolts.

[0009] Furthermore, a mounting block is fixedly installed on the top of the support plate. The mounting block has a movable groove, and a sliding column is provided in the movable groove. The bottom end of the sliding column slides through the support plate and is fixedly connected to the load-bearing sensing module. The top of the sliding column is connected to two symmetrically arranged clamping arms through a hinged clamping mechanism. Two pressure sensors are symmetrically fixedly connected to both sides of the mounting block. When the sliding column moves downward to the lowest point, the hinged clamping mechanism drives the clamping arms to clamp the pressure sensors. The pressure sensors are electrically connected to the alarm module.

[0010] Furthermore, the hinged clamping mechanism includes a hinge block, the bottom end of which is hinged to the top end of the sliding column, and two symmetrically arranged clamping units are hinged to the top end of the hinge block. Each clamping unit includes a hinged pull rod hinged to the hinge block, and a hinged swing rod is hinged to the free end of the hinged pull rod. The free end of the hinged swing rod is hinged to the hanging block, and the clamping arm is integrally fixedly installed on the hinged swing rod.

[0011] Furthermore, several springs are fixedly connected between the load-bearing sensing module and the load-bearing plate.

[0012] Furthermore, a protective sleeve is fixedly connected to the bottom end of the bearing plate and sleeved outside the load-bearing sensing module. Multiple lighting lamp beads are evenly embedded in the bottom end of the protective sleeve along the circumference.

[0013] Furthermore, a limiting pressure plate is fixedly sleeved on the column body of the sliding column located in the movable groove, and a control button for controlling the illumination of the lighting beads is provided directly below the limiting pressure plate and mounted on the bearing plate.

[0014] Furthermore, the alarm module is electrically connected to a buzzer and an alarm light.

[0015] Furthermore, the force value judgment algorithm pre-stored on the signal processing circuit board is used to implement the following judgment logic: The tensile force F and acceleration A are collected in real time at a fixed frequency; Calculate the rate of change of tension: K; When K exceeds the preset impact change rate threshold K thThe peak tensile force F exceeds the preset safety tensile force threshold F. th And the peak value of acceleration A exceeds the preset vibration threshold A. th When a real fall event occurs, an alarm command is generated and sent.

[0016] Furthermore, the alarm module is connected to a host computer.

[0017] Compared with the prior art, the present invention has the following features and beneficial effects: 1. This invention, through the coordinated operation of the tension sensor, triaxial accelerometer, and signal processing circuit board within the load-bearing sensing module, transforms the safety rope attachment point from a traditional purely mechanical passive load-bearing device into an intelligent device with state perception and active alarm capabilities. The force value judgment algorithm pre-stored on the signal processing circuit board, through the composite judgment of the tension change rate K, the peak tension F, and the peak acceleration A, can accurately distinguish between real fall events and tension fluctuations or accidental touch interference during normal operation, significantly reducing the false alarm rate and achieving accurate identification and active alarm of fall events.

[0018] 2. This invention achieves dual audible and visual alarms by simultaneously connecting a buzzer and an alarm light via an alarm module. Two high-brightness LED strobe lights are symmetrically positioned on both sides of the mounting block to avoid blind spots. The buzzer emits a high-decibel audible sound, ensuring that the warning signal can be promptly detected by surrounding personnel in noisy construction sites. Simultaneously, the alarm module is connected to a host computer, so even if the audible and visual alarms are not detected in time due to environmental noise or obstructed vision, safety management personnel can still receive accident information immediately and quickly organize emergency rescue, gaining valuable golden rescue time for fallen personnel.

[0019] 3. This invention, by setting up a linkage structure between the sliding column and the hinged clamping mechanism, when the lifting ring is subjected to tension, the sliding column slides downward to drive the clamping arm to clamp the pressure sensor, forming a linkage relationship of clamping when there is tension. The clamping state of the pressure sensor can serve as an effective verification signal of the loading state, forming multiple redundant judgments with the sensing data of the load-bearing sensing module. Even if the sensing part of the load-bearing sensing module is abnormal, the clamping action of the clamping arm itself forms an auxiliary limit for the sliding column, enhancing the structural stability of the anchoring point and improving the overall safety redundancy.

Detailed Implementation

[0022] The present invention will now be described in more detail with reference to the embodiments.

[0023] Example 1 Please see Figures 1 to 5 The distributed photovoltaic construction safety rope hanging point device of this embodiment includes a bearing plate 1, and a hanging clamping mechanism 100 is installed on the top of the bearing plate 1. In this embodiment, the hanging clamping mechanism 100 can be firmly clamped to the roof steel structure (such as steel beams and purlins) or the sturdy photovoltaic support rail.

[0024] A load-bearing sensing module 300 is installed at the bottom of the load-bearing plate 1. A suspension rope 3 is connected to the bottom of the load-bearing sensing module 300. A lifting ring 4 is fixedly connected to the bottom of the suspension rope 3. Workers can hang on the lifting ring 4 through the hanging ring on the safety working rope, thereby achieving safe high-altitude work.

[0025] Specifically, please refer to Figure 3 and Figure 5 The load-bearing sensing module 300 includes a housing 301.

[0026] The housing 301 contains a tension sensor 302 for collecting the tension of the suspension rope 3, a signal processing circuit board 303 with a pre-stored force value judgment algorithm, and a triaxial accelerometer 304 integrated on the signal processing circuit board 303 for real-time acquisition of vibration acceleration and angle change data of the signal processing circuit board 303. Both the triaxial accelerometer 304 and the tension sensor 302 are electrically connected to the signal processing circuit board 303.

[0027] Meanwhile, in order to enable timely alarms, an alarm module 8 is also provided at the top of the carrier plate 1, and the alarm module 8 is electrically connected to the signal processing circuit board 303.

[0028] As described above, after the operator attaches the hanging ring on the safety rope to the lifting ring 4, the tension on the lifting ring 4 is transmitted to the load-bearing sensing module 300 through the lifting rope 3. The tension sensor 302 inside the load-bearing sensing module 300 collects the tension data of the lifting rope 3 in real time, and the triaxial accelerometer 304 collects the vibration acceleration and angle change data of the signal processing circuit board 303 in real time. The two transmit the collected signals to the signal processing circuit board 303.

[0029] The signal processing circuit board 303 has a pre-stored force value judgment algorithm. By comprehensively analyzing the tension data, acceleration data, and angle change data, it can accurately determine whether the current attachment point is in a loaded state and identify whether a fall event has occurred.

[0030] When a fall-load event is detected, the signal processing circuit board 303 immediately triggers the alarm module 8 to issue an audible and visual alarm signal, thus realizing active alarm for the accident.

[0031] Through the coordinated operation of the tension sensor 302, the triaxial acceleration sensor 304, and the signal processing circuit board 303, the safety rope attachment point is transformed from a passive load-bearing structure into an intelligent device with status perception and active alarm capabilities, which can accurately identify the attachment status and fall events.

[0032] In the event of a fall, alarm module 8 can issue an alarm in a timely manner, preventing delays in rescue due to workers losing their ability to call for help or being in blind spots. This effectively improves the safety of high-altitude operations in distributed photovoltaic construction and meets the requirements of intelligent construction safety management.

[0033] Furthermore, the alarm module 8 is electrically connected to a buzzer 7 and an alarm light 6.

[0034] In this embodiment, a buzzer 7 capable of emitting a high-decibel audible sound is selected, and a high-brightness LED strobe light 6 is selected as the alarm light 6.

[0035] Please see Figure 1 The alarm module 8 is installed on the support plate 1. There are two alarm lights 6, which are symmetrically installed on both sides of the mounting block 9 to avoid blind spots. The buzzer 7 is installed on the top of the alarm module 8.

[0036] In the event of an accidental fall, the alarm module 8 will simultaneously activate the buzzer 7 and the alarm light 6. The buzzer 7 will emit a high-decibel buzzing sound, and the alarm light 6 will emit a strong light warning in the form of a high-brightness LED flashing. The two alarm lights 6 ensure that there are no blind spots in the field of vision from different angles, so that the warning signal can be noticed by people in the surrounding area in a timely manner.

[0037] Furthermore, the force value judgment algorithm pre-stored in the signal processing circuit board 303 is used to implement the following judgment logic: The tensile force F and acceleration A are collected in real time at a fixed frequency; Calculate the rate of change of tension: K; When K exceeds the preset impact change rate threshold K th The peak tensile force F exceeds the preset safety tensile force threshold F. th And the peak value of acceleration A exceeds the preset vibration threshold A. th When a real fall event occurs, an alarm command is generated and sent.

[0038] By using the triple criteria of tension change rate K, peak tension F, and peak acceleration A, the force value judgment algorithm can accurately distinguish between real fall events and tension fluctuations or accidental contact interference during normal operations.

[0039] The introduction of the rate of change of tensile force K can effectively identify the impact characteristics generated at the moment of fall, and the safe tensile force threshold F th After eliminating static tensile interference under normal loading conditions, the vibration threshold A th This further verifies the impact and vibration characteristics at the moment of impact.

[0040] The three-condition composite judgment mechanism significantly reduces the false alarm rate, avoids false triggering caused by normal movement of workers, equipment shaking or environmental vibration, ensures that alarm commands are only output when a real fall event occurs, improves the reliability and intelligence level of the device, and enables the safety rope attachment device to ensure operational safety without affecting normal construction efficiency.

[0041] Furthermore, the alarm module 8 is connected to a host computer. When a fall occurs, even if the sound and light alarms are not detected in time due to reasons such as noisy environment or obstructed view, the remote alarm signal on the host computer can ensure that safety management personnel are informed of the accident information as soon as possible and quickly organize emergency rescue.

[0042] Example 2 Please see Figures 1 to 4 In this embodiment, the safety rope hanging point device for distributed photovoltaic construction is based on the above embodiment one, with a hanging block 9 fixedly installed on the top of the bearing plate 1.

[0043] The mounting clamping mechanism 100 includes an arc-shaped groove 10 disposed at the top of the mounting block 9 and an arc-shaped cover plate 12 covering the top of the arc-shaped groove 10. An extension plate 11 extends outward integrally from both sides of the arc-shaped groove 10, and an extension plate 2 13 extends outward integrally from both sides of the arc-shaped cover plate 12. The extension plate 11 and the extension plate 2 13 are detachably connected by a number of locking bolts 14.

[0044] During installation, place the roof steel structure (such as steel beams or purlins) or photovoltaic bracket guide rail into the arc-shaped groove 10, and then cover the arc-shaped cover plate 12 on top of the arc-shaped groove 10 so that the arc-shaped groove 10 and the arc-shaped cover plate 12 together enclose and form a clamping space.

[0045] The extension plates 11 extending outward from both sides of the arc-shaped groove 10 and the extension plates 13 extending outward from both sides of the arc-shaped cover plate 12 are fitted together. A number of locking bolts 14 pass through the extension plates 11 and 13 and are tightened to achieve a detachable fastening connection.

[0046] The clamping structure, which uses an arc-shaped groove 10 and an arc-shaped cover plate 12, combined with the detachable connection of extension plate 11, extension plate 2 13 and locking bolt 14, has wide applicability.

[0047] The arc-shaped clamping space formed by the arc-shaped groove 10 and the arc-shaped cover plate 12 can accommodate common roof structural components such as steel beams, purlins and photovoltaic bracket guide rails of different diameters, avoiding the cumbersome operation of changing clamps for different structural components.

[0048] Example 3 Please see Figures 1 to 4 In this embodiment of the distributed photovoltaic construction safety rope hanging device, based on the above embodiment one or embodiment two, a hanging block 9 is fixedly installed on the top of the bearing plate 1, a movable groove 5 is opened on the hanging block 9, a sliding column 19 is set in the movable groove 5, the bottom end of the sliding column 19 slides through the bearing plate 1 and is fixedly connected to the load sensing module 300, and the top of the sliding column 19 is connected to two symmetrically arranged clamping arms 171 through the hinge clamping mechanism 200.

[0049] Two pressure sensors 18 are symmetrically fixedly connected to both sides of the mounting block 9. When the sliding column 19 moves downward to the lowest point, the hinged clamping mechanism 200 drives the clamping arm 171 to clamp the pressure sensor 18. The pressure sensor 18 is electrically connected to the alarm module 8.

[0050] When the operator is in the attached state, the pressure sensor 18 is always clamped by the clamping arm 171.

[0051] Specifically, the hinged clamping mechanism 200 includes a hinge block 15, the bottom end of which is hinged to the top end of the sliding column 19, and the top end of the hinge block 15 is hinged to two clamping units that are symmetrically arranged.

[0052] Please see Figure 2 The clamping unit has two clamping sub-units, which are respectively located at the front and rear ends of the hinge block 15.

[0053] Specifically, the clamping subunit includes a hinged pull rod 16 hinged to the hinged block 15, a hinged swing rod 17 hinged to the free end of the hinged pull rod 16, the free end of the hinged swing rod 17 hinged to the hanging block 9, and the clamping arm 171 integrally fixedly installed on the hinged swing rod 17.

[0054] The two hinged swing rods 17 of the two clamping subunits are connected by the same pin, so they can move synchronously to clamp or release.

[0055] As can be seen from the above description, when the operator attaches the safety rope to the lifting ring 4, the lifting ring 4 applies a downward pulling force to the sliding column 19 through the lifting rope 3 and the load sensing module 300, and the sliding column 19 slides downward in the movable groove 5.

[0056] When the sliding column 19 moves downward, it drives the hinge block 15, which is hinged to its top, to move downward in sync. The hinge block 15 pulls the hinge swing rod 17 around the hinge point with the hanging block 9 through the hinge pull rod 16, thereby driving the clamping arm 171, which is integrally fixed on the hinge swing rod 17, to rotate inward and clamp. When the sliding column 19 moves downward to the lowest point, the clamping arm 171 just clamps the two pressure sensors 18 that are symmetrically fixed on both sides of the hanging block 9.

[0057] Under normal load conditions, the lifting ring 4 continuously bears the weight of the worker and the tension generated by the work activities, the sliding column 19 remains at the lowest point, and the pressure sensor 18 is always clamped by the clamping arm 171.

[0058] When a fall occurs, the tension sensor 302, the triaxial acceleration sensor 304, and the signal processing circuit board 303 work together to trigger the alarm module 8 to sound an alarm. At the same time, the clamping status of the pressure sensor 18 can be used as an auxiliary judgment signal. The pressure sensor 18 is electrically connected to the alarm module 8 and can transmit the clamping status signal to the alarm module 8 or the signal processing circuit board 303 to verify the continuity of the mounting status and the effectiveness of the clamping mechanism.

[0059] The state in which the pressure sensor 18 is continuously clamped by the clamping arm 171 can serve as an effective verification signal for the mounting state. Together with the data collected by the tension sensor 302 and the triaxial acceleration sensor 304, it forms multiple redundant judgments, further improving the reliability of state recognition.

[0060] Furthermore, several springs are fixedly connected between the load-bearing sensing module 300 and the load-bearing plate 1.

[0061] When the operator removes the load and the lifting ring 4 no longer bears the tension, the restoring force of the spring pushes the load sensing module 300 to reset upward, causing the sliding column 19 to move upward, and the hinge clamping mechanism 200 to move in the opposite direction, causing the clamping arm 171 to release the pressure sensor 18, and the entire device returns to the initial unloaded state.

[0062] During normal loading operations, the spring is always in a stretched state, providing a stable reset preload for the load sensing module 300, while buffering the tension fluctuations generated when the operator moves normally, reducing impact interference to the tension sensor 302.

[0063] Furthermore, a protective sleeve 2 is fixedly connected to the bottom end of the bearing plate 1 and is sleeved outside the load sensing module 300. Multiple lighting beads 22 are evenly embedded in the bottom end of the protective sleeve 2 along the circumference.

[0064] When workers are attaching safety ropes or working at heights, the lighting bulb 22 can provide localized lighting, illuminating the lifting ring 4 and the surrounding work area. At night, in rainy weather, or at construction sites with insufficient light, the lighting bulb 22 provides sufficient light for workers to attach safety ropes, check the connection status of the lifting ring 4, and perform operations such as going up and down the roof, ensuring work safety.

[0065] Furthermore, a limiting pressure plate 20 is fixedly sleeved on the column body of the sliding column 19 located in the movable groove 5, and a control button 21 is provided directly below the limiting pressure plate 20, which is installed on the bearing plate 1 and used to control the illumination of the lighting beads 22.

[0066] When the worker attaches the safety rope to the lifting ring 4, the lifting ring 4 applies a downward pulling force to the sliding column 19 through the lifting rope 3 and the load sensing module 300. When the sliding column 19 slides down to the lowest point, the limiting pressure plate 20 fixedly sleeved on the sliding column 19 moves down accordingly and presses the control button 21 directly below. After the control button 21 is triggered, the power supply circuit of the lighting beads 22 is turned on, so that the multiple lighting beads 22 at the bottom of the protective sleeve 2 are lit.

[0067] When the operator removes the load and the sliding column 19 returns to its original position under the action of the spring, the limit plate 20 moves upward and disengages from the control button 21. The control button 21 is then reset and disconnected, and the lighting bulb 22 automatically turns off. The lighting bulb 22 only lights up when the device is in the loaded state and the sliding column 19 moves down to the working position.

[0068] It ensures sufficient lighting in the operating area during operation and automatically cuts off power when not in use, thus achieving energy-saving effects.

[0069] The working principle of this invention is as follows: After the operator attaches the hanging ring on the safety rope to the lifting ring 4, the tension on the lifting ring 4 is transmitted to the load-bearing sensing module 300 through the lifting rope 3. The tension sensor 302 inside the load-bearing sensing module 300 collects the tension data of the lifting rope 3 in real time, and the triaxial acceleration sensor 304 collects the vibration acceleration and angle change data of the signal processing circuit board 303 in real time. The two transmit the collected signals to the signal processing circuit board 303.

[0070] The signal processing circuit board 303 has a pre-stored force value judgment algorithm. By comprehensively analyzing the tension data, acceleration data, and angle change data, it can accurately determine whether the current attachment point is in a loaded state and identify whether a fall event has occurred.

[0071] When a fall-load event is detected, the signal processing circuit board 303 immediately triggers the alarm module 8 to issue an audible and visual alarm signal, thus realizing active alarm for the accident.

[0072] Through the coordinated operation of the tension sensor 302, the triaxial acceleration sensor 304, and the signal processing circuit board 303, the safety rope attachment point is transformed from a passive load-bearing structure into an intelligent device with status perception and active alarm capabilities, which can accurately identify the attachment status and fall events.

[0073] In the event of a fall, alarm module 8 can issue an alarm in a timely manner, preventing delays in rescue due to workers losing their ability to call for help or being in blind spots. This effectively improves the safety of high-altitude operations in distributed photovoltaic construction and meets the requirements of intelligent construction safety management.
