Description

Technical Field

[0001] This invention relates to the field of mountain photovoltaic module installation technology, and in particular to a fall protection device for mountain photovoltaic module installation. Background Technology

[0002] During the construction of photovoltaic power stations in mountainous areas, the accidental falling of small tools, fasteners, or scrap materials is a common safety hazard when performing high-altitude operations such as installing photovoltaic modules and welding brackets on sloping slopes. Although these falling objects are not large or heavy, they possess considerable kinetic energy after falling from a height of tens of meters, easily causing injury to personnel and equipment below and potentially triggering secondary accidents. Therefore, quickly setting up a reliable fall-prevention buffer and interception barrier below the work platform is an essential safety measure on construction sites.

[0003] Currently, to address this need, the following two methods are mainly used on-site: First, traditional construction safety nets or dense mesh nets are used, which are erected by workers before work begins by binding with ropes and manually pulling. While this method can provide some interception, in rugged mountainous terrain, the nets are difficult to hang evenly, tension cannot be guaranteed, and installation and dismantling rely entirely on manual climbing and operation, making the process time-consuming, labor-intensive, and inefficient. Furthermore, there is a risk of falls from heights during the erection process. Second, prefabricated rigid guardrails or barriers are used. These devices are bulky, extremely difficult to transport and handle in mountainous terrain, and difficult to adapt to complex slopes, resulting in poor deployment flexibility and difficulty in quickly moving with the work area. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a safety protection device for preventing falls during the installation of photovoltaic modules in mountainous areas.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fall protection device for mountain photovoltaic modules, comprising a base plate, a foundation component on the top of the base plate, the foundation component comprising two rotating frames, the two rotating frames being fixedly connected to the two sides of the top of the base plate respectively, a first rotating rod being rotatably connected between the two sides of the inner cavity of the rotating frames, a device rod and a combination rod being fixedly connected to the surfaces of the two first rotating rods respectively, a first extension groove being provided inside the device rod, a second extension groove being provided inside the combination rod, a first threaded rod being provided at the bottom of the inner cavity of the first extension groove, a first threaded sleeve being provided on the surface of the first threaded rod, a second rotating rod being provided between the two sides of the inner cavity of the second extension groove, a protective net being fixedly connected to the surface of the first threaded sleeve, and the end of the protective net near the second rotating rod being fixedly connected to the second rotating rod.

[0006] As a preferred embodiment of the present invention, a fixing component is provided at the bottom of the base plate. The fixing component includes two second threaded sleeves, both of which are fixedly connected to the two sides of the top of the base plate. A second threaded rod is threadedly connected inside the second threaded sleeve. A drill bit is fixedly connected to the bottom of the second threaded rod, and a handle is fixedly connected to the end of the second threaded rod away from the drill bit.

[0007] As a preferred embodiment of the present invention, a limiting component is provided on one side of the rotating frame. The limiting component includes a limiting port and a fixing barrel. One end of the first rotating rod passes through the rotating frame and extends to the outside of the rotating frame. The limiting port is opened at the end of the first rotating rod extending to the outside of the rotating frame. The fixing barrel is sleeved on the surfaces of the two first rotating rods extending to the outside of the rotating frame. A second spring is fixedly connected inside the fixing barrel. Sliding blocks are fixedly connected to both sides of the second spring. A limiting block that cooperates with the limiting port is fixedly connected to the side of the sliding block near the limiting port.

[0008] As a preferred embodiment of the present invention, the surface of the fixed bucket is provided with a sliding opening, and a pulling block is fixedly connected to the side of the sliding block near the sliding opening. The end of the pulling block near the sliding opening passes through the sliding opening and extends to the outside of the sliding opening.

[0009] As a preferred embodiment of the present invention, a protective component is provided inside the first extension groove. The protective component includes a drive box, which is located at the top of the device rod. A motor is provided inside the drive box. The output shaft of the motor is fixedly connected to a third rotating rod. The end of the third rotating rod away from the motor passes through the drive box and the device rod in sequence and extends into the interior of the first extension groove.

[0010] As a preferred embodiment of the present invention, the third rotating rod extends into the first extension groove and is fixedly connected to an assembly barrel at one end. The assembly barrel has fixing grooves on both sides of its inner cavity. A third spring is fixedly connected inside the fixing groove. An assembly block is fixedly connected to the end of the third spring away from the fixing groove. An assembly rod that cooperates with the assembly barrel is fixedly connected to the top of the first threaded sleeve. The surface of the assembly rod has several assembly openings that cooperate with the assembly blocks.

[0011] As a preferred embodiment of the present invention, a triggering component is provided inside the assembly barrel. The triggering component includes a switch, which is fixedly connected inside the assembly barrel. An alarm is fixedly connected to the top of the rotating frame. The switch is used to start the motor and the alarm.

[0012] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, through the setting of basic components and protective components, allows the motor to directly transmit rotational power to the first threaded sleeve via the engagement of the assembly bucket and assembly rod at the end of the third rotating rod. This drives the sleeve to precisely rise and fall along the first threaded rod, thereby linearly controlling the hanging length and tension of the protective net fixedly connected to it. This design completely changes the traditional operation mode of relying on manual throwing, pulling, and binding of safety nets in mountain high-altitude operations. It not only increases the deployment efficiency several times, but more importantly, it allows operators to remotely control and complete all operations from a safe platform position, completely avoiding high-risk physical labor in steep and edge-prone areas. At the same time, it ensures the consistency and repeatability of the tension of the protective net, laying the foundation for reliable protective performance in the future.

[0013] 2. This invention creatively designs a purely mechanical fall detection and alarm triggering chain. Its core lies in rigidly or trigger-basedly connecting the protective net, the first threaded sleeve, the assembly rod, the assembly bucket, and the built-in switch. When a falling object impacts the protective net, the downward pull forces the first threaded sleeve to rotate and rise on the first threaded rod. This mechanical displacement is transmitted through the assembly rod, causing its tip to penetrate deeper into the assembly bucket, ultimately pressing the trigger switch and instantly activating the alarm circuit. This mechanism does not rely on any electronic sensors, directly converting the kinetic energy of the falling object into a trigger signal, achieving a millisecond-level response. It overcomes the shortcomings of existing technologies where protective nets only have a passive protection function and cannot actively issue warnings. It can immediately alert all personnel in the work area when an accident occurs, effectively preventing secondary dangers and providing valuable time and information for timely rescue.

[0014] 3. The base plate fixing component of this invention adopts a manual screw-in ground anchoring scheme. By rotating the handle, the second threaded rod with a drill bit is driven to drill into the ground surface. This structure is specifically designed for the gravel and soil mountainous environment common in photovoltaic power stations, providing good initial anti-overturning ability. At the same time, the device rod and the combination rod are hinged to the base plate through the rotating frame and equipped with a quick locking mechanism consisting of a fixed barrel, spring and limit block. This allows the entire protective facade to be quickly erected and locked or pressed down and released like a suitcase handle. This combination of stable anchoring and quick folding design perfectly balances the stability and portability required for field equipment, solves the pain points of difficult transportation and long deployment time of large safety equipment in mountainous areas, and realizes the high mobility of equipment as it moves with the work site.

[0015] 4. In this invention, the limiting component for locking the support rod in the vertical position is ingeniously and reliably designed. The fixing bucket simultaneously connects to the shaft ends of the two first rotating rods. Through the internal symmetrical springs pushing the sliding block and the limiting block, they can be simultaneously locked into the limiting slots of the rotating rods on both sides. This process only requires the rod to be erected in place to automatically complete the locking, which is crisp and intuitive. To unlock, simply press the pulling blocks on both sides at the same time to retract the limiting block and lay the rod down. This mechanism eliminates the need for traditional pins, bolts, and other small parts that require alignment with holes, use tools, or are easily lost. It achieves true one-click locking and unlocking, greatly simplifying the on-site operation steps and improving the speed of equipment deployment and storage, as well as the user experience.

[0016] 5. The overall design of this invention embodies the unity of functional integration and system robustness. It organically integrates electric net adjustment, mechanical fall triggering, manual mountain fixation, and rapid mechanical locking into a complete safety protection unit. Each subsystem is relatively independent yet works collaboratively: for example, in the extreme case of power outage, the purely mechanical triggering alarm function remains effective; the complex motor transmission mechanism is sealed and protected, while the exposed mechanical locking mechanism is simple and robust. This design philosophy ensures that the core safety functions of the device do not completely fail due to a single change in conditions in harsh and variable outdoor industrial environments, providing multi-layered, highly redundant safety guarantees and significantly improving the all-weather reliability and service life of the entire equipment.

[0020] refer to Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a fixing assembly is provided at the bottom of the base plate 1. The fixing assembly includes two second threaded sleeves 30, both of which are fixedly connected to the two sides of the top of the base plate 1. A second threaded rod 31 is threadedly connected to the inside of the second threaded sleeve 30. A drill bit 32 is fixedly connected to the bottom of the second threaded rod 31. A handle 33 is fixedly connected to the end of the second threaded rod 31 away from the drill bit 32. A limit assembly is provided on one side of the rotating frame 20. The limit assembly includes a limit port 40 and a fixing barrel 41. One end of the first rotating rod 21 passes through the rotating frame 20 and extends to the outside of the rotating frame 20. The limit port 40 is opened in the first rotating rod. One end of the first rotating rod 21 extends to the outside of the rotating frame 20. The fixed barrel 41 is sleeved on the surface of the two first rotating rods 21 extending to the outside of the rotating frame 20. The inside of the fixed barrel 41 is fixedly connected to a second spring 42. Both sides of the second spring 42 are fixedly connected to sliding blocks 43. The side of the sliding block 43 near the limiting port 40 is fixedly connected to a limiting block 44 that cooperates with the limiting port 40. The surface of the fixed barrel 41 is provided with a sliding opening 45. The side of the sliding block 43 near the sliding opening 45 is fixedly connected to a pulling block 46. The end of the pulling block 46 near the sliding opening 45 passes through the sliding opening 45 and extends to the outside of the sliding opening 45.

[0021] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a protective assembly is provided inside the first extension groove 24. The protective assembly includes a drive box 50, which is located at the top of the device rod 22. A motor 51 is installed inside the drive box 50, and the output shaft of the motor is fixedly connected to a third rotating rod 52. The end of the third rotating rod 52 away from the motor 51 passes through the drive box 50 and the device rod 22 and extends into the interior of the first extension groove 24. The end of the third rotating rod 52 extending into the interior of the first extension groove 24 is fixedly connected to an assembly barrel 53. Fixed openings are provided on both sides of the inner cavity of the assembly barrel 53. The groove 54 is fixedly connected to a third spring 55. The end of the third spring 55 away from the groove 54 is fixedly connected to an assembly block 56. The top of the first threaded sleeve 27 is fixedly connected to an assembly rod 57 that works with the assembly barrel 53. The surface of the assembly rod 57 has several assembly ports 58 that work with the assembly block 56. The assembly barrel 53 is equipped with a triggering component, which includes a switch 60. The switch 60 is fixedly connected to the inside of the assembly barrel 53. The top of the rotating frame 20 is fixedly connected to an alarm 61.

[0022] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the operator first moves the base plate 1 to the preset mountain installation position. By rotating the handles 33 on both sides, the second threaded rod 31 is driven to rotate inside the second threaded sleeve 30, so that the drill bit 32 at the bottom is screwed into or pressed into the ground, completing the initial fixation of the device. Then, the device rod 22 and the combination rod 23 are lifted from the flat position and rotated around the axis of the first rotating rod 21 to the vertical working position. The fixing bucket 41 is sleeved on the shaft ends extending from the two first rotating rods 21. At this time, the pull blocks 46 on both sides are pressed inward. The pull blocks 46 drive the sliding block 43 to compress the second spring 42, so that the limiting block 44 retracts. When the first rotating rod 21 rotates to the position where the limiting port 40 is aligned with the limiting block 44, the pull blocks 46 are released. The second spring 42 pushes the sliding block 43 and the limiting block 44 to pop out and lock into the limiting port 40, thereby locking the device rod 22 and the combination rod 23 in the upright position.

[0023] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, next, the motor 51 in the drive box 50 is started. The output shaft of the motor 51 drives the third rotating rod 52 and the assembly barrel 53 fixed at its end to rotate. The assembly block 56 in the assembly barrel 53 is embedded in the assembly port 58 on the surface of the assembly rod 57 under the elastic force of the third spring 55, so that the assembly barrel 53 and the assembly rod 57 are combined. The rotation of the assembly barrel 53 drives the first threaded sleeve 27 to rotate on the first threaded rod 26 and move downward through the assembly rod 57, thereby releasing the protective net 29 connected to the first threaded sleeve 27. The other end of the protective net 29 is connected to the second rotating rod 28. As the first threaded sleeve 27 moves downward, the protective net 29 is pulled out from the second rotating rod 28 and hangs down to form a protective area. When the protective net 29 hangs down to a suitable, slightly loose standby state, the motor 51 is turned off. At this time, the first threaded sleeve 27 and the assembly rod 57 are in a low position, and the top of the assembly rod 57 is not deeply inserted into the assembly barrel 53 to press the switch 60.

[0024] refer to Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, when a tool or component falls and impacts the protective net 29, the downward force pulls the protective net 29. This pulling force may cause the second rotating rod 28 to rotate slightly within the second extension groove 25 to cushion the impact. On the other hand, the pulling force is transmitted to the first threaded sleeve 27, attempting to pull the first threaded sleeve 27 to rotate and rise along the first threaded rod 26. When the impact force is large enough, the first threaded sleeve 27 overcomes frictional resistance and rotates and rises, driving the assembly rod 57 to rise synchronously. The top of the assembly rod 57 rises accordingly and inserts deeper into the assembly barrel 53 until its top presses against the switch 60 fixed inside the assembly barrel 53. After the switch 60 is triggered, the circuit is connected, and the device installed in the first threaded rod 26 is immediately activated. The alarm 61 on the top of the rotating frame 20 emits an audible and visual alarm signal. After the operation is completed, the motor 51 is restarted to reverse its direction. The motor 51 drives the third rotating rod 52 and the assembly bucket 53 to rotate in the opposite direction. Through the cooperation of the assembly block 56 and the assembly port 58, the assembly rod 57 and the first threaded sleeve 27 are driven to rotate and move downward, thereby gathering the protective net 29 and raising it to the initial height. After the net is gathered, the motor 51 is turned off, the pull block 46 is pressed to retract the limit block 44, the lock on the first rotating rod 21 is released, the device rod 22 and the combination rod 23 are laid down, and finally, the handle 33 is rotated in the opposite direction to retract the second threaded rod 31 and the drill bit 32 from the ground, completing all the operations.

[0025] Working principle: Before use: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the operator first moves the base plate 1 to the work point next to the photovoltaic array. By rotating the handles 33 on both sides, the second threaded rod 31 is driven to rotate and descend within the second threaded sleeve 30 until the drill bit 32 drills into or presses into the ground, completing the initial fixation. Then, the two first rotating rods 21 are pulled upwards, rotating them from a retracted state parallel to the base plate 1 to an upright working state perpendicular to the base plate 1. Next, the fixing bucket 41 is fitted onto the shaft ends of the two first rotating rods 21 extending out of the rotating frame 20. The pull blocks 46 on both sides are pressed inwards, causing the sliding block 43 to compress the second spring 42, causing the limiting block 44 to retract. When the first rotating rod 21 rotates to the position where the limiting port 40 is aligned with the limiting block 44, the pull block 46 is released. The second spring 42 pushes the sliding block 43 and the limiting block 44 to pop out and lock into the limiting port 40, thereby locking the device rod 22 and the combined rod 23 in a vertical position. Next, the motor 51 in the drive box 50 is started. The motor 51 drives the third rotating rod 52 to rotate, which in turn drives the assembly barrel 53 fixed at its end to rotate. The assembly block 56 inside the assembly barrel 53 is embedded in the assembly port 58 on the surface of the assembly rod 57 under the action of the third spring 55, thereby realizing the combination of power. The assembly barrel 53 drives the assembly rod 57 to rotate. Since the assembly rod 57 is fixedly connected to the first threaded sleeve 27, and the first threaded sleeve 27 is threadedly connected to the first threaded rod 26, the rotational motion is converted into the downward linear motion of the first threaded sleeve 27 along the first threaded rod 26. The first threaded sleeve 27 moves downward and gradually releases the protective net 29 fixedly connected to it. The other end of the protective net 29 is wrapped around or connected to the second rotating rod 28. When the protective net 29 droops to a suitable, slightly loose protective tension, the motor 51 is turned off. At this time, the first threaded sleeve 27 and the assembly rod 57 on it are in the low stroke position, and the top of the assembly rod 57 is not inserted into the deep pressure switch 60 inside the assembly barrel 53.

[0026] When using: Refer to Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, when a tool or component falls from a height, it will first impact the protective net 29. The impact force of the fall will exert a downward pull on the protective net 29. This pull will attempt to drive the second rotating rod 28 to rotate within the second extension groove 25 to cushion the impact. On the other hand, it will be transmitted through the protective net 29 to the first threaded sleeve 27, attempting to pull the first threaded sleeve 27 upward along the first threaded rod 26. Under a sufficiently large impact force, the first threaded sleeve 27 will overcome the thread friction and begin to rotate and rise, driving the assembly rod 57 to rise synchronously. The top of the assembly rod 57 will rise and insert into the internal cavity of the assembly barrel 53. As it continues to rise, the top of the assembly rod 57 will eventually press against the switch 60 fixed inside the assembly barrel 53. After the switch 60 is triggered, the circuit is connected, and the alarm 61 installed on the top of the rotating frame 20 will be activated immediately, emitting a strong audible and visual alarm signal to warn the workers above that a falling object has occurred.

[0027] After use: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 After the operation is completed, the motor 51 is restarted and reversed. The motor 51 drives the assembly barrel 53 to rotate in the opposite direction through the third rotating rod 52. The assembly block 56 in the assembly barrel 53 drives the assembly rod 57 and the first threaded sleeve 27 to rotate through the assembly port 58, so that the first threaded sleeve 27 moves downward along the first threaded rod 26, thereby re-gathering and tightening the protective net 29 and lifting it into the device rod 22. After the protective net 29 is completely tightened, the motor 51 is turned off, and the pull blocks 46 on both sides are pressed inward to make the limit block 44 retract from the limit port 40, releasing the lock on the first rotating rod 21. The device rod 22 and the combination rod 23 are pulled down and flattened on the base plate 1 for transportation or storage. Finally, the handle 33 is rotated in the opposite direction to pull the second threaded rod 31 and the drill bit 32 out of the ground, completing the entire storage work.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
