Description

Technical Field

[0001] This invention relates to the field of multifunctional work platform technology, specifically a multifunctional work platform for emergency repair of photovoltaic power plants. Background Technology

[0002] The multi-functional emergency repair platform for photovoltaic power stations is mainly used for high-altitude inspection, replacement, and reinforcement of photovoltaic modules and supporting components after damage or failure. It is suitable for emergency repair work in photovoltaic power stations with different outdoor terrains, specifically for emergency repair operations in photovoltaic power stations deployed in various locations such as mountains, slopes, and factory roofs.

[0003] Currently, most high-altitude emergency repairs of photovoltaic systems utilize conventional hydraulic lifting platforms. These platforms have a coordinated support system, with the four corner supports moving synchronously during lifting. This allows for uniform height adjustment of the entire platform, but when facing uneven construction sites such as mountains, slopes, or rooftops, the height of the four corner supports cannot be adjusted individually. The platform's working surface will tilt synchronously with the slope of the site, increasing the risk of workers losing balance and falling, resulting in poor operational stability. Furthermore, the tilted platform is difficult to fit snugly against the tilted photovoltaic panels for precise emergency repairs, making it highly adaptable to different sites.

[0004] Meanwhile, the existing windproof structures of lifting work platforms mostly rely on external electronic control sensors and drive components to achieve wind balance. They rely on the electronic control structure to adjust the cable tension to counteract wind disturbances. The entire electronic control windproof structure is complicated to set up and has high energy consumption. Under complex outdoor wind conditions, the electronic control components are easily affected by temperature, humidity, wind and sand and malfunction. The platform is prone to large swings due to the wind force at high altitudes, which continuously increases the safety hazards of high-altitude emergency repair operations. The platform is not suitable for all-weather outdoor operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-functional emergency repair platform for photovoltaic power plants, thereby resolving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-functional emergency repair platform for photovoltaic power plants includes a mobile vehicle and a repair platform, wherein a hydraulic lifting platform is fixedly installed on the top surface of the mobile vehicle.

[0007] The hydraulic lifting platform has electric telescopic rods fixedly installed at the four corners of the lifting end. Each electric telescopic rod has a universal ball fixedly installed at its top. The four corners of the bottom surface of the emergency repair platform are respectively fixedly installed with ball sleeves that can be matched with the universal balls. The universal balls are limited and embedded in the ball sleeves to achieve universal hinge connection.

[0008] The four corners of the bottom surface of the emergency repair platform are connected to four cables, and the lower ends of the four cables converge to connect to a set of lead weights, which are suspended in the air directly below the center of the bottom surface of the emergency repair platform.

[0009] The plumb bob includes a main plumb bob and a sub-plumb. The bottom surfaces of both the main plumb bob and the sub-plumb are provided with threaded blind holes, and the top surface of the sub-plumb is provided with threaded protrusions.

[0010] The sinker can be eccentrically displaced by high-altitude wind disturbances, pulling the corresponding cable in the opposite direction to tighten it.

[0011] Preferably, the outer wall of the universal ball is covered with a damping and anti-slip rubber sleeve, which is fitted to the inner wall of the ball sleeve to increase the rotational damping of the universal ball hinge and reduce the amount of hinge gap wobble.

[0012] Meanwhile, the damping and anti-slip rubber sleeve can buffer the impact of hard hinges brought by high-altitude lateral wind pressure, weaken the hard friction loss between the universal ball and the ball sleeve, adapt to the normal high-wind operation environment in the open field of photovoltaic fields, and simultaneously improve the fit and sealing of the hinge position to prevent sand and dust and photovoltaic panel debris from entering the hinge gap and jamming the rotating structure.

[0013] Preferably, the bottom end of the ball sleeve has a through hole for the cable to pass through and be fixed, and the top end of the cable is locked and fixed inside the through hole.

[0014] To avoid misalignment and friction with the bottom of the ball sleeve when the cable is deflected by force, it ensures that the eccentric pulling force of wind disturbance can be transmitted to the ball sleeve without loss, and works with the universal ball universal hinge structure to quickly correct the local tilt posture of the repair platform.

[0015] Preferably, a fixed limiting guide ring is provided at the center of the bottom surface of the emergency repair platform, and all four cables are arranged through the limiting guide ring.

[0016] Meanwhile, the limiting guide ring can regulate the vertical force angle of the cable, ensuring that each cable is subjected to uniform force when the plumb bob is eccentrically displaced, preventing overload deformation of one side of the cable, and making it suitable for high-altitude emergency repair operations on photovoltaic roofs with varying heights.

[0017] Preferably, the lead weight is a modular counterweight block with a rope groove at the center of the top surface, and the bottom ends of the four cables are locked together inside the rope groove.

[0018] The inner side of the rope groove is fitted with anti-slip interlocking texture, which can lock the bottom end of the cable at the convergence position, prevent the bottom end of the cable from slipping and dispersing the counterweight tension. The split structure can flexibly increase or decrease the number of sub-pile combinations according to the wind level of the photovoltaic field, and adaptively adjust the overall counterweight stabilization force.

[0019] Preferably, the tilt sensor is fixed to the side wall of the hydraulic lifting platform, and the tilt sensor is electrically connected to the control end of the four electric telescopic rods.

[0020] It can be used in conjunction with lead weights for passive wind pressure correction to form an active + passive dual leveling system. It can make real-time fine adjustments to level the base caused by the tilting of photovoltaic sloping roofs and undulating terrain, ensuring that the working surface of the emergency repair platform is always in a stable state and reducing the risk of overturning during high-altitude operations.

[0021] Preferably, the mobile vehicle is equipped with anti-slip parking legs at the bottom, and the bottom end of the anti-slip parking legs is equipped with an arc-shaped anti-slip pad that conforms to the uneven ground, which can stably support the mobile vehicle and prevent the transmission of micro-vibrations of the vehicle body to the emergency repair platform.

[0022] The curved anti-slip mat can adapt to various irregular substrates such as sand, mud, and hardened roads in photovoltaic fields, increase ground friction resistance, isolate the resonance transmission of mobile vehicle engines and surrounding construction equipment, and avoid high-frequency vibration affecting the accuracy of photovoltaic wiring and component inspection operations by emergency repair personnel.

[0023] Preferably, the emergency repair platform is surrounded by an integral protective fence, and an opening door for emergency repair personnel is provided on one side of the protective fence.

[0024] The inner side of the protective fence is fitted with a flexible buffer protective pad to cushion the impact of personnel bumping into each other and tools slipping and hitting each other. The opening and closing door is equipped with a self-locking buckle structure, which can automatically lock when working at height to prevent personnel from accidentally stepping on it and falling. At the same time, it facilitates the convenient transfer of repair tools and photovoltaic faulty components into and out of the platform.

[0025] Preferably, the cable is made of highly flexible, tensile-resistant stainless steel wire rope, and the surface of the cable is coated with a photovoltaic ultraviolet anti-corrosion coating.

[0026] It is suitable for photovoltaic power stations exposed to strong sunlight, alternating day and night temperature differences, and acid, alkali and dust corrosion conditions in the site. It slows down the rusting and aging of cables and the speed of steel wire breakage. The highly flexible material can adapt to the multi-angle eccentric pulling and bending of lead weights without bending cracks or strand breakage under stress, thus ensuring the long-term stability of pulling and correcting.

[0027] Preferably, the top of the ball sleeve is detachably fixed to the bottom surface of the emergency repair platform by bolts, and the bottom flange of the universal ball is detachably fixed to the top of the electric telescopic rod.

[0028] The wear-out universal ball, damping anti-slip rubber sleeve, and ball sleeve can be disassembled and installed separately in the later stage, without the need to disassemble the entire emergency repair platform and electric telescopic pole structure, which reduces the difficulty of field operation, maintenance and replacement of photovoltaic power stations and reduces the cost of component replacement and operation.

[0029] Compared with the prior art, the present invention provides a multi-functional emergency repair platform for photovoltaic power plants, which has the following beneficial effects: In this invention, a hydraulic lifting platform is used to achieve coarse adjustment of the height at high altitudes. Combined with four independently controllable electric telescopic rods and a universal ball joint and ball sleeve universal hinge structure, it breaks through the shortcomings of traditional lifting platforms that are linked to the platform and cannot be leveled separately. For uneven installation sites such as mountain photovoltaic, slope photovoltaic, and factory roof photovoltaic, the height of the four corner supports can be independently fine-tuned, and the tilt angle of the emergency repair platform can be adaptively corrected. It ensures that the working surface of the emergency repair platform is level all day long, solving the pain points of traditional working platforms such as tilting on slopes, unsafe construction, and inability to fit the photovoltaic panel surface. It is suitable for emergency repair of photovoltaic power stations in all areas.

[0030] In this invention, four cables converge to connect a central suspended lead weight. Utilizing the principle of wind disturbance linkage, when the platform is shifted by the wind, it can cause the lead weight to shift eccentrically, tightening the corresponding side cable in the opposite direction to form a passive damping traction balance. Without the need for an external electrically controlled wind stabilization structure, it can autonomously counteract high-altitude wind disturbances, significantly reducing the swaying amplitude of the repair platform, improving the safety of high-altitude workers, and making it suitable for outdoor open-air all-weather repair operations.

[0031] In this invention, the lead weight adopts a modular structure with a main weight and detachable sub-weights. It is connected by threaded protrusions and threaded blind holes, which makes it easy to assemble and disassemble, and the counterweight is adjustable. It can be used for lightweight operation in light wind conditions, reducing the load on the electric telescopic pole and reducing the energy consumption of the hydraulic lifting platform. In high wind conditions, the sub-weights can be quickly added to increase the counterweight and strengthen the cable traction and platform stability. It can be adapted to different wind levels and outdoor conditions without replacing the overall counterweight components, and adapts to the day and night and seasonal wind changes of photovoltaic power stations.

[0034] Please see Figures 1 to 6 The present invention provides a technical solution: A multi-functional emergency repair platform for photovoltaic power plants includes a mobile vehicle 1 and a repair platform 5, with a hydraulic lifting platform 2 fixedly installed on the top of the mobile vehicle 1.

[0035] The hydraulic lifting platform 2 has electric telescopic rods 3 vertically fixed at the four corners of the lifting end. Each electric telescopic rod 3 has a universal ball 4 fixed at its top. The bottom of the emergency repair platform 5 has ball sleeves 6 that can be engaged and adapted with the universal ball 4 at the four corners. The universal ball 4 is limited and embedded in the ball sleeve 6 to achieve universal hinge connection.

[0036] Four cables 7 are connected to the four corners of the bottom surface of the emergency repair platform 5. The lower ends of the four cables 7 converge and connect to a set of lead weights 8, which are suspended in the air directly below the center of the bottom surface of the emergency repair platform 5.

[0037] The lead weight 8 includes a main weight 81 and a secondary weight 82. Both the main weight 81 and the secondary weight 82 have threaded blind holes 83 on their bottom surfaces, and the secondary weight 82 has threaded protrusions 84 on its top surface.

[0038] The lead weight 8 can be eccentrically displaced by high-altitude wind disturbances, pulling the corresponding cable 7 in the opposite direction to tighten it.

[0039] The main weight 81 has a threaded blind hole 83 at the bottom and no threaded protrusion on the top surface. One or more sub-weights 82 can be screwed into the threaded blind hole 83 on the bottom surface of the counterweight block by the threaded protrusion 84 on the top surface, so as to achieve the end-to-end series splicing and the overall counterweight weight of the weight can be freely combined and adjusted.

[0040] When a crosswind blows across the high altitude and causes the repair platform 5 to shift to one side, the cable 7 on the shifted side is stretched, and the lead weight 8, which is constrained by the bottom ends of the four cables 7, is pulled by the difference in cable length and simultaneously produces an eccentric displacement in the same direction.

[0041] The lead weight 8 generates a constant downward pull force based on its own weight. In the eccentric state, the pull force is pulled and tightened in the opposite direction along the corresponding side cable 7 that has been stretched. The counterweight pull force is used to counteract the lateral thrust of the platform brought by the wind, constrain the platform's swaying and twisting, and achieve passive wind protection and deviation correction.

[0042] In this invention, a hydraulic lifting platform 2 is used to achieve coarse adjustment of the height at high altitudes. Combined with the four independently controllable electric telescopic rods 3, the universal ball joint 4 and the ball sleeve 6, the invention breaks through the shortcomings of traditional lifting platforms that are linked to the platform and cannot be leveled separately. For uneven installation sites such as mountain photovoltaic, slope photovoltaic, and factory roof photovoltaic, the height of the four corner supports can be independently fine-tuned, and the tilt angle of the emergency repair platform 5 can be adaptively corrected. The working surface of the emergency repair platform 5 is guaranteed to be level all day long. This solves the pain points of traditional operating platforms that are tilted when working on slopes, are unsafe to construct, and cannot be aligned with the photovoltaic panel surface. It is suitable for emergency repair of photovoltaic power stations in all areas.

[0043] In this invention, four cables 7 converge and connect to a central suspended plumb bob 8. Utilizing the principle of wind disturbance linkage, when the platform is shifted by the wind, the plumb bob 8 will shift eccentrically, tightening the corresponding side cable 7 in the opposite direction, forming a passive damping traction balance. Without the need for an external electrically controlled wind stabilization structure, it can autonomously counteract high-altitude wind disturbances, significantly reducing the swaying amplitude of the repair platform 5, improving the safety of high-altitude workers, and making it suitable for outdoor open-air all-weather repair operations.

[0044] In this invention, the lead sinker 8 adopts a modular structure with a main sinker 81 and a detachable sub-sinker 82. It is connected by threaded protrusions 84 and threaded blind holes 83, which makes it easy to assemble and disassemble, and the counterweight is adjustable. It can be used for lightweight operation in light wind conditions, reduce the load on the electric telescopic pole 3, and reduce the energy consumption of the hydraulic lifting platform 2. In strong wind conditions, the sub-sinker 82 can be quickly added to increase the counterweight and strengthen the traction and stability of the cable 7. It can be adapted to different wind levels and outdoor conditions without replacing the overall counterweight components, and adapts to the day and night and seasonal wind changes of photovoltaic power stations.

[0045] Preferably, the outer wall of the universal ball 4 is covered with a damping and anti-slip rubber sleeve 9, which is fitted to the inner wall of the ball sleeve 6 to increase the hinge rotation damping of the universal ball 4 and reduce the amount of hinge gap wobble.

[0046] Meanwhile, the damping anti-slip rubber sleeve 9 can buffer the impact of hard hinges brought by high-altitude lateral wind pressure, weaken the metal hard friction loss between the universal ball 4 and the ball sleeve 6, adapt to the normal high wind operation environment in the open field of photovoltaic fields, and simultaneously improve the fit and sealing of the hinge position to prevent sand and dust and photovoltaic panel debris from entering the hinge gap and jamming the rotating structure.

[0047] Preferably, the bottom end of the ball sleeve 6 has a through hole 10 for the cable 7 to be threaded and fixed, and the top end of the cable 7 is locked and fixed inside the through hole 10.

[0048] To prevent the cable 7 from shifting under stress and rubbing against the bottom of the ball sleeve 6, ensuring that the eccentric pulling force of wind disturbance can be transmitted to the ball sleeve 6 without loss, and to quickly correct the local tilt of the repair platform 5 in conjunction with the universal ball 4 universal hinge structure.

[0049] Preferably, the bottom center of the emergency repair platform 5 is fixed with a limiting guide ring 11, and all four cables 7 are laid through the limiting guide ring 11.

[0050] Meanwhile, the limiting guide ring 11 can regulate the vertical force angle of the cable 7, ensuring that each cable 7 is subjected to uniform force when the plumb bob 8 is eccentrically displaced, preventing overload deformation of the cable 7 on one side, and adapting to high-altitude emergency repair operations on photovoltaic roofs with varying heights.

[0051] Preferably, the lead weight 8 is a split-type counterweight block, with a rope groove 12 opened in the center of the top surface of the lead weight 8, and the bottom ends of the four cables 7 are locked together inside the rope groove 12.

[0052] The inner side of the rope groove 12 is fitted with anti-slip interlocking texture, which can lock the bottom end of the cable 7 to converge, prevent the bottom end of the cable 7 from slipping and dispersing the counterweight tension. The split structure can flexibly increase or decrease the number of sub-pile 82 combinations according to the wind level of the photovoltaic field, and adaptively adjust the overall counterweight stabilization force.

[0053] Preferably, a tilt sensor 13 is fixed to the side wall of the hydraulic lifting platform 2, and the tilt sensor 13 is electrically connected to the control end of the four electric telescopic rods 3.

[0054] It can be used in conjunction with the lead weight 8 for passive wind pressure correction to form an active + passive dual leveling system. It can make real-time fine adjustments to level the base caused by the tilting of photovoltaic sloping roofs and undulating terrain, ensuring that the working surface of the emergency repair platform 5 is always in a stable state and reducing the risk of overturning during high-altitude operations.

[0055] Preferably, the bottom of the mobile vehicle 1 is provided with anti-slip parking legs 14, and the bottom end of the anti-slip parking legs 14 is provided with an arc-shaped anti-slip pad 15 that conforms to the uneven ground, which can stably support the mobile vehicle 1 and prevent the transmission of micro-vibrations of the vehicle body to the emergency repair platform 5.

[0056] The curved anti-slip mat 15 can adapt to various irregular bases such as sand, mud, and hardened road surfaces in the photovoltaic field, increase grounding friction resistance, isolate the engine of the mobile vehicle 1 and the resonance transmission of surrounding construction equipment, and avoid high-frequency vibration affecting the accuracy of photovoltaic wiring and component inspection operations by emergency repair personnel.

[0057] Preferably, the emergency repair platform 5 is surrounded by an integrated protective fence 16, and an opening and closing door 17 for emergency repair personnel to enter and exit is opened on one side of the protective fence 16.

[0058] The inner side of the protective fence 16 is fitted with a flexible buffer protective pad to cushion the impact of personnel bumping into each other and tools slipping and hitting each other. The opening and closing door 17 is equipped with a self-locking buckle structure, which can automatically lock when working at height to prevent personnel from accidentally stepping on it and falling. At the same time, it facilitates the convenient transfer of emergency repair tools and photovoltaic faulty components into and out of the platform.

[0059] Preferably, the cable 7 is made of highly flexible, tensile-resistant stainless steel wire rope, and the surface of the cable 7 is coated with a photovoltaic ultraviolet anti-corrosion coating.

[0060] It is suitable for photovoltaic power stations exposed to strong sunlight, alternating day and night temperature differences, and acid, alkali and dust corrosion conditions in the site. It slows down the rusting and aging of cables and the speed of steel wire breakage. The highly flexible material can be adapted to the multi-angle eccentric pulling and bending of lead weights, and will not cause bending cracks or strand breakage under stress, thus ensuring the long-term stability of pulling and correcting.

[0061] Preferably, the top of the ball sleeve 6 is detachably fixed to the bottom surface of the emergency repair platform 5 by bolts, and the bottom flange of the universal ball 4 is detachably fixed to the top of the electric telescopic rod 3.

[0062] The wear-out universal ball 4, damping anti-slip rubber sleeve 9, and ball sleeve 6 can be disassembled and installed individually in the later stages, without the need to disassemble the entire structure of the emergency repair platform 5 and electric telescopic pole 3, reducing the difficulty of field operation, maintenance and replacement of photovoltaic power stations and reducing the cost of component replacement and operation.

[0063] The working principle of this device is as follows: The operator maneuvers the mobile vehicle 1 to a level working area below the fault points of photovoltaic power station components, inverters, etc., locks the parking brake of the mobile vehicle 1, completes the bottom positioning of the whole machine, avoids horizontal slippage of the vehicle body during the operation, and builds a solid bottom foundation for high-altitude emergency repair.

[0064] In the initial state, the hydraulic lifting platform 2 is in its lowest retracted state, the electric telescopic rod 3 is in its original retracted height, the universal ball 4 is embedded in the ball sleeve 6 at the bottom of the repair platform 5, the repair platform 5 and the hydraulic lifting platform 2 are kept coaxially attached, the cable 7 hangs down naturally, and the lead weight 8 is stationary and suspended in the air.

[0065] Based on the installation height of the photovoltaic panels and the height of the faulty components from the ground, the hydraulic lifting platform 2 is activated, which drives the four electric telescopic rods 3 at the top, the universal ball 4, and the emergency repair platform 5 connected above to rise and fall vertically in sync, raising the emergency repair platform 5 to the appropriate working height for the photovoltaic fault area.

[0066] Once the height is reached, shut down hydraulic lifting platform 2 and lock the lifting height. Operators can then stand on the top surface of emergency repair platform 5 to carry out preliminary maintenance preparations.

[0067] Photovoltaic power stations are often located on uneven terrain such as mountains, slopes, and rooftops. After the hydraulic lifting platform 2 is raised, the top surface is prone to slight tilting. At this time, the extension and retraction length of the four corner electric telescopic rods 3 can be independently adjusted, relying on the universal joint structure of the top universal ball 4 and the ball sleeve 6.

[0068] The repair platform 5 can adaptively deflect at multiple angles and finely adjust its tilt to compensate for the tilt error of the hydraulic lifting platform 2, always keeping the top surface of the repair platform 5 level, eliminating the risk of workers slipping or tools rolling off, and adapting to the working conditions of photovoltaic power stations on slopes.

[0069] When the wind force of the high-altitude airflow at outdoor photovoltaic power stations is unstable, and the crosswind blows directly on the repair platform, the platform will tend to shift, sway, and twist.

[0070] At this time, the platform offset will pull on the cable 7 on one side, and the plumb bob 8 suspended below the center will be eccentrically displaced due to wind disturbance inertia. It will pull the corresponding cable 7 in the opposite direction to tighten it quickly. The weight of the plumb bob 8 will be used to counteract the wind thrust and constrain the twisting and swaying of the emergency repair platform 5.

[0071] Workers stand on the stable, level repair platform 5 to complete emergency repairs such as replacing damaged photovoltaic modules, connecting lines, and inspecting junction boxes.

[0072] Adjust the overall weight of the lead weight as needed for different outdoor working conditions, such as strong winds and light winds.

[0073] In light wind conditions, only the main sinker 81 is used alone. Its weight is relatively small, and the cable 7 has a moderate pulling force, which does not restrict minor adjustments to the platform.

[0074] Under high wind conditions, the threaded protrusion 84 on the top surface of the sinker 82 is screwed into the threaded blind hole 83 on the bottom surface of the main sinker 81 to achieve the splicing and combination of the main sinker 81 and the sinker 82, thereby increasing the overall weight of the sinker 8.

[0075] Multiple sets of weights 82 can be connected in series through threaded protrusions 84 and threaded blind holes 83 to gradually increase the counterweight and meet the high-strength stability requirements in strong wind environments.

[0076] After the photovoltaic fault point was repaired, the workers withdrew from the repair platform 5, first disassembled the excess spliced ​​sub-weights 82, and then reset the lead weights 8 as counterweights.

[0077] The four corner electric telescopic rods 3 are retracted synchronously, so that the emergency repair platform 5 returns to a horizontal and coaxial state.

[0078] Then, the hydraulic lifting platform 2 is lowered back to its lowest initial height, the universal ball 4 and ball sleeve 6 are kept in hinged limit position, the cable 7 and the plumb bob 8 fall back to their original positions naturally, and finally the mobile vehicle 1 is driven away from the work area to complete the entire process of a single emergency repair.
