Description

Technical Field

[0001] This invention belongs to the field of new energy technology, specifically an outdoor photovoltaic inverter mounting bracket with wind-resistant reinforcement function. Background Technology

[0002] In solar photovoltaic power generation systems, photovoltaic inverters are the core equipment for converting direct current to alternating current. They are usually installed outdoors to accommodate the arrangement of photovoltaic modules. In outdoor environments, photovoltaic inverter mounting racks must withstand multiple effects such as wind loads, rainwater erosion, and impacts from debris. Therefore, high requirements are placed on their wind resistance reinforcement, drainage protection, and ease of maintenance.

[0003] However, existing outdoor photovoltaic inverter mounting racks still have many shortcomings: poor wind resistance; most mounting racks adopt a rigid structure design, which can provide some support, but its ability to buffer wind loads is insufficient. Under strong winds, they are prone to fatigue damage due to wind vibration effects, or the lack of flexible buffer structures causes wind loads to be directly transferred to the main body of the rack, leading to structural deformation and loosening of connection nodes; unreasonable drainage design; the side walls of the mounting rack lack efficient water guiding and drainage environment, and rainwater easily accumulates on the surface of the rack or in the gaps between components, which not only increases the additional load, but also accelerates the corrosion of metal components and shortens the service life of the mounting rack; poor adaptability to wind-borne debris; lack of structures to break up flexible debris and to protect against cutting hard debris; debris can easily become entangled in and impact the mounting rack, damaging structural stability and even causing safety hazards; insufficient convenience of installation and maintenance; wind-resistant reinforcement and supporting functional components often use complex fixing methods, making disassembly and assembly difficult, and the replacement of worn parts is time-consuming and labor-intensive, significantly increasing operation and maintenance costs.

[0004] Therefore, it is urgent to optimize the structure of outdoor photovoltaic inverter mounting racks to improve their wind resistance, drainage efficiency, debris adaptability, and maintenance convenience, thereby ensuring the stable operation of photovoltaic inverters in complex outdoor environments. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the technical problem of wind-resistant and reinforced outdoor photovoltaic inverter mounting brackets mentioned in the background art, the technical solution adopted by the present invention is as follows: The wind-resistant and reinforced outdoor photovoltaic inverter mounting bracket of the present invention includes a mounting bracket body. A water guide groove is provided on the side wall of the mounting bracket body, and the water guide groove is evenly distributed on the side wall of the mounting bracket body. A first fixing plate is fixedly connected to the side wall of the mounting bracket body. A damping rod is installed on the side wall of the first fixing plate. A rotating rod is installed inside the damping rod. The rotating rod is rotatably engaged with the side wall of the first fixing plate. A first stop is fixedly connected to the side wall of the rotating rod. The mounting frame has a first baffle with filter holes on its side wall, which are evenly distributed on the side wall of the rotating rod. A breaking component is fixed to the side wall of the rotating rod, and a guiding component is fixed to the side wall of the mounting frame body. Through the above structure, multiple unloading and guidance of wind and rain loads are achieved. The water guide channel quickly drains rainwater to avoid the superposition of water loads. The damping rod, together with the rotating rod and the first baffle, converts the impact energy of the wind into rotational kinetic energy and dissipates it through damping, buffering the direct impact of the wind on the mounting frame. The filter holes prevent rainwater from accumulating on the first baffle and increasing its weight. The breaking component and the guiding component work together to handle debris in the wind and optimize the wind and rain flow direction, thereby improving the overall stability of the mounting frame under complex weather conditions.

[0006] Preferably, the crushing assembly includes a second fixing plate, which is evenly distributed on the side wall of the rotating rod. Crushing pins are screwed to the side wall of the second fixing plate, and each crushing pin is screwed to a fixing nut. Through the above structure, efficient crushing and easy maintenance of flexible debris are achieved. The crushing pins can pierce and crush flexible debris such as ribbons and thin plastics, avoiding debris from getting tangled and stuck on the mounting frame structure. The screw connection + fixing nut design allows the crushing pins to be easily disassembled and replaced, reducing the difficulty of later maintenance.

[0007] Preferably, the guiding component includes trapezoidal blocks, with multiple sets of trapezoidal blocks provided on the side wall of the mounting frame body. The side wall of the trapezoidal blocks is provided with drainage grooves, which are evenly distributed on the side wall of the trapezoidal blocks. Through the above structure, rainwater and wind force are diverted and guided. The trapezoidal structure of the trapezoidal blocks guides the wind force to disperse in a direction not perpendicular to the mounting frame, reducing the direct impact of the wind. The drainage grooves quickly divert rainwater, improve drainage efficiency, and prevent rainwater from accumulating and increasing weight on the side wall of the mounting frame.

[0008] Preferably, the bottom of the inner wall of the trapezoidal block is provided with a mounting groove, and a mounting plate is installed inside the mounting groove. A cutting blade is fixed to the top of the mounting plate, and the cutting blades are evenly distributed on the top of the mounting plate. Through the above structure, cutting protection against hard debris and easy maintenance of the component are achieved. The cutting blade can cut and break hard debris such as small branches and hard plastic blocks, reducing their impact damage to the mounting frame. The cooperation between the mounting plate and the mounting groove allows the cutting blade assembly to be disassembled as a whole, which is convenient for inspection and replacement.

[0009] Preferably, the mounting bracket body and the sidewall of the mounting groove are provided with mounting holes, which are evenly distributed on the sidewalls of the mounting bracket body and the mounting groove. A fixing pin is slidably fitted on the inner sidewall of the mounting hole, and the fixing pin is fixed to the bottom of the mounting plate. Through the above structure, the guide component can be quickly assembled and disassembled. The sliding fit between the fixing pin and the mounting hole allows the mounting plate to be quickly fixed or disassembled, which greatly improves the maintenance convenience of the guide component and facilitates timely inspection and replacement of components such as cutting tools.

[0010] Preferably, an L-shaped baffle is fixed to the side wall of the first baffle. The L-shaped baffle is set at a right angle. Through the above structure, the wind and rainwater are optimized and guided. The right angle structure of the L-shaped baffle better bears the wind force and disperses some of the wind force to both sides, reducing the impact of wind load in the vertical direction. At the same time, it helps to block and guide the flow of rainwater, and further optimizes the drainage effect in conjunction with the filter holes.

[0011] Preferably, every two trapezoidal blocks are distributed in a mirror-like inclined manner. Through the above structure, adaptive guidance of wind loads in multiple directions is achieved. The mirror-like inclined trapezoidal blocks can adapt to winds coming from different angles, efficiently guiding the wind to the sides or top, avoiding the formation of eddies or concentrated impacts of wind around the mounting frame, and enhancing wind resistance under complex wind direction conditions.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. The outdoor photovoltaic inverter mounting bracket with wind-resistant reinforcement function described in this invention achieves multiple unloading and guidance of wind and rain loads through the structural arrangement of water guide channels and damping rods. The water guide channels quickly drain rainwater to avoid the superposition of water loads. The damping rods, together with the rotating rods and the first baffle, convert the impact energy of the wind into rotational kinetic energy and dissipate it through damping, buffering the direct impact of the wind on the mounting bracket. The water filter holes prevent rainwater from accumulating and increasing the weight on the first baffle. The breaking component and the guiding component work together to handle debris in the wind and optimize the wind and rain flow direction, thereby improving the overall stability of the mounting bracket under complex weather conditions.

[0014] 2. The outdoor photovoltaic inverter mounting bracket with wind-resistant reinforcement function described in this invention achieves efficient crushing of flexible debris and easy maintenance through the structural design of fixing nuts and crushing pins. The crushing pins can pierce and crush flexible debris such as ribbons and thin plastics, avoiding debris from getting tangled and jamming the mounting bracket structure. The screw connection + fixing nut design allows the crushing pins to be easily disassembled and replaced, reducing the difficulty of later maintenance. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 2As shown in the embodiment of the present invention, the outdoor photovoltaic inverter mounting bracket with wind-resistant reinforcement function includes a mounting bracket body 1. The mounting bracket body 1 has water guide grooves 11 evenly distributed on its side wall. A first fixing plate 12 is fixedly connected to the side wall of the mounting bracket body 1. A damping rod 13 is installed on the side wall of the first fixing plate 12. A rotating rod 14 is installed inside the damping rod 13. The rotating rod 14 is rotatably engaged with the side wall of the first fixing plate 12. A first baffle 15 is fixedly connected to the side wall of the rotating rod 14. The first baffle 15 has water filter holes 16 evenly distributed on its side wall. A breaking component is fixedly connected to the side wall of the rotating rod 14. A guiding component is fixedly connected to the side wall of the mounting bracket body 1. During operation, when used outdoors, rainwater flows along the side wall of the mounting bracket body 1 and is evenly distributed. The drainage channel 11 of the cloth quickly guides rainwater to discharge, avoiding rainwater accumulation and increasing load. When strong winds hit, the wind acts on the first baffle 15, causing the rotating rod 14 to rotate around the first fixed plate 12. At this time, the damping rod 13 uses its damping characteristics to buffer the rotation, consume wind load energy, and reduce the impact on the mounting frame body 1. When rainwater comes into contact with the first baffle 15, it is quickly discharged through the evenly distributed filter holes 16, avoiding rainwater accumulation on the baffle and increasing weight. The breaking component on the side wall of the rotating rod 14 can break up debris in the wind, and the guiding component further guides the wind / rainwater. This step enables the drainage channel 11 to achieve rapid rainwater discharge and reduce the impact of water load. The cooperation of the damping rod 13, the rotating rod 14, and the first baffle 15 consumes wind energy through rotation and damping, improving wind resistance and buffering capacity. The filter holes reduce rainwater accumulation, and the breaking and guiding components work together to enhance the structural stability in wind and rain environments.

[0025] like Figure 2 As shown, the crushing assembly includes a second fixed plate 2, which is evenly distributed on the side wall of the rotating rod 14. Crushing pins 22 are screwed to the side wall of the second fixed plate 2. Each crushing pin 22 is screwed to a fixing nut 21. During operation, when the rotating rod 14 rotates, the evenly distributed second fixed plates 2 rotate accordingly. The crushing pins 22, screwed to the side wall of the second fixed plate 2 via the fixing nuts 21, pierce and crush flexible debris in the air. If the crushing pin 22 is worn, the fixing nuts 21 can be loosened for replacement. This step allows the crushing pins 22 to effectively crush flexible debris, preventing debris from entangled and jamming the mounting frame. The screw connection + fixing nut 21 design enables convenient disassembly and assembly of the crushing pins 22, facilitating later maintenance.

[0026] like Figure 4As shown, the guiding component includes trapezoidal blocks 3, with multiple sets of trapezoidal blocks 3 on the side wall of the mounting frame body 1. Drainage channels 31 are formed on the side wall of each trapezoidal block 3, and are evenly distributed. During operation, multiple sets of trapezoidal blocks 3 are distributed on the side wall of the mounting frame body 1. When exposed to wind and rain, the drainage channels 31 on the side wall of the trapezoidal blocks divert and guide rainwater, accelerating drainage. Simultaneously, the trapezoidal structure of the trapezoidal blocks 3 guides the wind direction, reducing the direct impact of wind on the mounting frame. This process improves drainage efficiency by diverting rainwater through the trapezoidal blocks 3, while also guiding wind force to reduce direct impact. The even distribution of the drainage channels 31 further optimizes drainage, synergistically enhancing wind resistance and drainage performance.

[0027] like Figure 2 As shown, the bottom of the inner wall of the trapezoidal block 3 is provided with a mounting groove 4, and a mounting plate 41 is installed inside the mounting groove 4. A cutting blade 42 is fixed to the top of the mounting plate 41. The cutting blades 42 are evenly distributed on the top of the mounting plate 41. During operation, the mounting plate 41 is installed in the mounting groove 4 at the bottom of the inner wall of the trapezoidal block 3. The evenly distributed cutting blades 42 on the top of the mounting plate 41 can cut and break hard debris in the wind, preventing it from impacting the mounting frame and causing damage. This step uses the cutting blades 42 to break hard debris, reduce impact damage to the mounting frame, and protect the structural integrity. The mounting plate 41 and the mounting groove 4 cooperate to facilitate the overall installation and maintenance of the cutting blades 42.

[0028] like Figure 3 As shown, mounting holes 5 are provided on the side walls of the mounting bracket body 1 and the mounting groove 4. The mounting holes 5 are evenly distributed on the side walls of the mounting bracket body 1 and the mounting groove 4. A fixing pin 51 is slidably fitted on the inner side wall of the mounting hole 5. The fixing pin 51 is fixed to the bottom of the mounting plate 41. When installing the mounting plate 41, the fixing pin 51 fixed to its bottom is aligned with the mounting hole 5 on the side wall of the mounting bracket body 1 and the mounting groove 4 and inserted to quickly fix it. When disassembling, the fixing pin 51 is pulled out. The operation is simple. Through this step, the sliding fit between the mounting hole 5 and the fixing pin 51 is achieved, realizing the quick installation and removal of the mounting plate 41, which greatly improves the maintenance convenience of the guide component and facilitates timely inspection and replacement of parts.

[0029] like Figure 2 As shown, an L-shaped baffle 6 is fixedly connected to the side wall of the first baffle 15. The L-shaped baffle 6 is set at a right angle. When working, the L-shaped baffle 6 is fixedly connected to the side wall of the first baffle 15 at a right angle. When the wind is acting, the right angle structure of the L-shaped baffle 6 better bears the wind force and guides some of the wind force to both sides, reducing vertical impact. In rainy weather, the L-shaped baffle 6 helps to block and guide rainwater, and optimizes drainage in conjunction with the filter hole 16. Through this step, the right angle design of the L-shaped baffle 6 can optimize the bearing and guidance of wind, disperse wind load, and at the same time help guide rainwater, thus improving the overall performance of wind resistance and drainage.

[0030] like Figure 2 As shown, every two trapezoidal blocks 3 are arranged in a mirror-like tilt. During operation, every two trapezoidal blocks 3 are arranged in a mirror-like tilt. This layout allows the space between the trapezoidal blocks 3 to more efficiently guide wind from multiple directions. When wind blows towards the mounting frame from different angles, the mirror-like tilted trapezoidal blocks 3 guide the wind to the sides or top, preventing the wind from forming eddies or concentrated impacts around the mounting frame. Through this step, the mirror-like tilted trapezoidal blocks 3 can adapt to wind loads from multiple directions, guide the flow more efficiently, reduce the adverse effects of wind such as eddies, and further enhance the wind resistance under complex wind conditions.

[0031] During operation, when used outdoors, rainwater flows along the side wall of the mounting frame body 1. The evenly distributed water guide channels 11 quickly guide the rainwater out, preventing rainwater accumulation and increased load. When strong winds hit, the wind acts on the first baffle 15, causing the rotating rod 14 to rotate around the first fixed plate 12. At this time, the damping rod 13 uses its damping characteristics to buffer the rotation, consuming wind load energy and reducing the impact on the mounting frame body 1. When rainwater contacts the first baffle 15, it is quickly discharged through the evenly distributed filter holes 16, preventing rainwater from accumulating on the baffle and increasing its weight. The breaking components on the side wall of the rotating rod 14 can break up debris in the wind, and the guiding components further guide the wind / rainwater. This process enables the water guide channels 11 to quickly discharge rainwater, reducing the impact of water load. The damping rod 13 and the rotating rod 1... 4. The first baffle 15, through rotation and damping, consumes wind energy, improves wind resistance and buffering capacity, reduces rainwater accumulation through the water filter holes, and the crushing and guiding components work together to enhance structural stability in windy and rainy environments. When the rotating rod 14 rotates, the second fixed plate 2, evenly distributed on the side wall, rotates accordingly. The crushing pin 22, connected to the side wall of the second fixed plate 2 by screws through the fixing nut 21, will pierce and crush flexible debris in the wind. If the crushing pin 22 is worn, it can be replaced by loosening the fixing nut 21. This step allows the crushing pin 22 to effectively crush flexible debris and avoid debris from getting tangled and stuck on the mounting frame. The screw connection + fixing nut 21 design enables convenient disassembly and assembly of the crushing pin 22, facilitating later maintenance. Multiple sets of trapezoidal blocks 3 are distributed on the side wall of the mounting frame body 1. During wind and rain, the drainage channels 31 on the side wall of the trapezoidal block divert and guide rainwater, accelerating drainage. Simultaneously, the trapezoidal structure of the trapezoidal block 3 guides the wind direction, reducing the direct impact of wind on the mounting frame. This step improves drainage efficiency by diverting rainwater and guiding wind force to reduce direct impact. The evenly distributed drainage channels 31 further optimize drainage, synergistically enhancing wind resistance and drainage performance. An mounting plate 41 is installed in the mounting groove 4 at the bottom of the inner side wall of the trapezoidal block 3. Evenly distributed cutting blades 42 on the top of the mounting plate 41 can cut and break hard debris in the wind, preventing it from impacting and damaging the mounting frame. This step utilizes the cutting blades 42 to break hard debris, reducing impact damage to the mounting frame and protecting structural integrity. The mounting plate 41 cooperates with the mounting groove 4 to facilitate... For the overall installation and maintenance of the cutting blade 42, when installing the mounting plate 41, simply align the fixing pin 51 fixed at its bottom with the mounting hole 5 on the side wall of the mounting bracket body 1 and the mounting groove 4, and insert it for quick fixation. For disassembly, simply pull out the fixing pin 51. This simple operation allows for the sliding fit between the mounting hole 5 and the fixing pin 51, enabling quick assembly and disassembly of the mounting plate 41. This significantly improves the maintenance convenience of the guide assembly, facilitating timely inspection and replacement of components. The first baffle 15 has a right-angled L-shaped baffle 6 fixed to its side wall. When wind is applied, the right-angled structure of the L-shaped baffle 6 better absorbs the wind force and guides some of it to the sides, reducing vertical impact. In rainy weather, the L-shaped baffle 6 assists in blocking and guiding rainwater, optimizing drainage in conjunction with the filter hole 16.This step optimizes the wind reception and guidance of the right-angle design of the L-shaped baffle 6, dispersing wind loads and simultaneously guiding rainwater, thus synergistically improving wind resistance and drainage performance. The mirrored, tilted arrangement of every two trapezoidal blocks 3 allows the space between them to more efficiently guide wind from multiple directions. When wind blows towards the mounting frame from different angles, the mirrored, tilted trapezoidal blocks 3 direct the wind to the sides or top, preventing the formation of eddies or concentrated impacts around the mounting frame. This step allows the mirrored, tilted trapezoidal blocks 3 to adapt to multi-directional wind loads, more efficiently guiding airflow and reducing the effects of eddies and other adverse wind conditions, further enhancing wind resistance under complex wind conditions.
