Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a pressure-resistant and windproof photovoltaic bracket. Background Art

[0002] Solar photovoltaic power generation is a green energy that uses sunlight to provide clean energy to humans. Photovoltaic modules absorb solar energy and convert it into other needed energy. The installation of photovoltaic modules requires a photovoltaic bracket. Photovoltaic modules are generally installed in batches in flat and wide areas, which are easily affected by direct natural winds. This requires the use of windproof photovoltaic brackets.

[0003] The current photovoltaic brackets are generally installed in outdoor open-air places. When installed in open-air places, first of all, in some bad weather, the photovoltaic brackets are easily shaken and loosened. Long-term shaking will cause certain damage to the photovoltaic panels. In addition, if there is a strong natural wind, it is easy to overturn the photovoltaic panels, causing a large degree of economic losses. Some current wind-resistant structures are relatively complex and cannot achieve automatic locking. They require electronic devices for assistance. However, electronic components are easily damaged after being exposed to the sun and rain for a long time in open-air places. The wind-resistant effect is very general.

[0016] Compared with the prior art, the present invention provides a pressure-resistant and wind-proof photovoltaic bracket with the following beneficial effects:

[0017] 1. The pressure-resistant and windproof photovoltaic bracket can achieve two-way locking of the entire frame and photovoltaic panels through the wind-resistant components, and the entire locking structure uses the external natural wind as the power source. When the external natural wind is stronger, it drives the blades at a high speed, converting the rotational centrifugal force into horizontal and vertical pulling force to self-lock the entire frame, thereby improving the wind and pressure resistance of the entire photovoltaic bracket and improving the stability of the entire photovoltaic bracket. The entire locking is bidirectional, which can not only protect the stability of the photovoltaic panel, but also maintain the stability of the entire photovoltaic bracket. There is no need for active control of electronic components. Direct use of natural wind can achieve automatic locking, thereby improving the overall wind resistance.

[0018] 2. The pressure-resistant and windproof photovoltaic bracket is provided with an inclined slot with an open structure. When the natural wind is too strong and the centrifugal force reaches the limit, the sliding pin will disengage from the position of the inclined slot, thereby releasing the lock on the photovoltaic panel. Then, the counterweight frame slides down due to the gravity, controlling the lateral movement of the transverse tooth plate, and then using the engagement of the gears to drive multiple frames to change their angles, so that multiple frames are converted to a flat posture, reducing the large wind resistance caused by the tilt of the frame, so that it can be automatically laid flat and retracted in the state of strong natural wind, thereby realizing automatic protection of the photovoltaic panel.

[0019] 3. This pressure-resistant and windproof photovoltaic bracket can control the rotation of the pointer by converting the rotation of centrifugal force into lateral movement through the pressure display component. The rotation of the pointer is used to judge the magnitude of the tensile force that the photovoltaic bracket can withstand at this time, providing an indication effect for subsequent safe operations.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-8A pressure-resistant and wind-proof photovoltaic bracket includes a base 1; a stand 2; a photovoltaic module 4; and a wind-resistant component 3, which is used to improve the wind resistance and pressure resistance of the base 1 and the photovoltaic module 4; the stand 2 is fixed on the base 1, and the photovoltaic module 4 is arranged on the base 1; the wind-resistant component 3 includes a rotating centrifugal device and a double locking device; the rotating centrifugal device can lock the position of the photovoltaic module 4 and the position of the base 1 through the double locking device according to the intensity of the natural wind.

[0031] In this embodiment, the rotating centrifugal device includes a hollow rotating shaft 302, which is rotatably connected to the stand 2. Two centrifugal rods 305 are rotatably connected to the hollow rotating shaft 302. One end of the centrifugal rod 305 is fixedly connected to a centrifugal ball 304, and the other end of the centrifugal rod 305 is fixedly connected to a fixed gear 306. The two fixed gears 306 are meshed with a sliding square shaft 303. The sliding square shaft 303 is slidably connected to the inside of the hollow rotating shaft 302. A blade 301 is fixedly installed on the surface of the hollow rotating shaft 302. The right end of the sliding square shaft 303 is connected to the double locking device through a transmission member. The natural wind generated by the outside world will directly blow the blades 301 to rotate. When the blades 301 are rotating, they will drive the two centrifugal balls 304 to rotate synchronously. Through the rotational connection between the centrifugal rods 305 and the hollow rotating shaft 302, the centrifugal force will be gradually used to drive the two centrifugal rods 305 to open. When the centrifugal rods 305 are open, they will rotate at an angle on the hollow rotating shaft 302, and then drive the rotation of the fixed gear 306, and then drive the sliding square shaft 303 to slide horizontally inside the hollow rotating shaft 302. The entire device uses the rotation of the blades 301 caused by natural wind, and then uses the centrifugal force generated by the rotation to convert it into lateral pulling force to achieve the locking of the photovoltaic bracket. The stronger the natural wind, the greater the centrifugal force will be, and the lateral displacement thrust generated will increase. As the lateral thrust increases, the double locking device and the transmission of the lateral thrust will automatically form a double locking of tension and compression for the photovoltaic panel 41 and the entire base 1, which can not only reduce the mutual swing between the photovoltaic panels 41, but also ensure that the entire base 1 is stably "adsorbed" on the ground, thereby improving the overall pressure resistance and wind resistance of the photovoltaic bracket.

[0032] Furthermore, the transmission member includes a sliding shaft 308, the left end of which is rotatably connected to the sliding square shaft 303 via a bearing ring 309. The interior of the sliding shaft 308 is provided with a slot 307, and a sliding pin 316 is connected to the interior of the slot 307. The sliding shaft 308 is connected to a double locking device. The photovoltaic assembly 4 includes a frame 42, on which a plurality of photovoltaic panels 41 are mounted. The frame 42 is rotatably connected to the base 1, and the multiple frames 42 are arranged in a linearly inclined manner. The slot 307 is provided to provide sliding space for the counterweight frame 310 and the sliding shaft 308. The entire device utilizes the configuration of the transmission member to convert the rotational force into a lateral thrust. By utilizing the lateral thrust, the entire photovoltaic bracket is locked, thereby improving its wind resistance.

[0033] Furthermore, the dual locking device includes a first locking device and a second locking device. The first locking device includes a counterweight frame 310. Pull rings 311 are fixedly connected to both sides of the counterweight frame 310. The pull rings 311 are connected to tensioning cables 44. The tensioning cables 44 are serially connected to the frame 42. The counterweight frame 310 is provided with an inclined slot 317. A sliding pin 316 is slidably connected within the inclined slot 317. The counterweight frame 310 is slidably connected to the stand 2 via a V-shaped slot. When the sliding shaft 308 moves laterally, the sliding pin 316 is controlled to slide within the inclined slot 317 on the counterweight frame 310. This oblique sliding principle provides an upward thrust to the counterweight frame 310. This upward thrust on the counterweight frame 310 pulls the tensioning cables 44 connected to its left and right sides upward. Since the tensioning cables 44 are serially connected to the frame 42, the frame 42 is tightened. And at this time, if the wind becomes stronger, the rotation speed of the hollow shaft 302 will become faster and faster, and the rotational centrifugal force generated on the centrifugal ball 304 will become greater, so the lateral thrust will be greater, and the pulling force on the frame 42 will be greater, and the entire photovoltaic panel 41 will be more stable.

[0034] In addition, the bottom of the counterweight frame 310 is rotatably connected to a threaded sleeve 314, the internal thread of the threaded sleeve 314 is connected to a threaded rod 315, the bottom of the threaded rod 315 is connected to a support 313, the bottom of the support 313 is rotatably connected to a support rod 312, the bottom of the support rod 312 is rotatably connected to a transverse gear plate 43, a plurality of small gears 45 are engaged on the transverse gear plate 43, the small gears 45 are fixed on the frame body 42, and the transverse gear plate 43 is slidably connected to the base 1. When the sliding pin 316 moves laterally to the extreme position, it will disengage from the right opening of the inclined slot 317. The counterweight frame 310 will then lose the upward thrust and the engaged state of the sliding pin 316. At this time, the counterweight frame 310 will sink under its own gravity, driving the support 313 downward. Then, the rotation connection of the two support rods 312 will drive the relative lateral movement of the two horizontal toothed plates 43. Then, the meshing transmission of the gears and the toothed plates will drive the multiple small gears 45 to rotate, thereby driving the multiple frames 42 to "lie flat" and achieve automatic flatness. Because in the flat state, the wind resistance of natural wind blowing on the frames 42 will be reduced, thereby maximizing the safety protection of the photovoltaic panels 41 and preventing damage to the photovoltaic panels 41 caused by excessive wind resistance. The threaded sleeve 314 can adjust the height of the support 313 in the early stage of installation of the photovoltaic bracket, and then adjust the lateral position of the horizontal toothed plates 43 to ultimately adjust the overall tilt angle of the photovoltaic panels 41.

[0035] In addition, the second locking device includes two ground spikes 323, which are fixed on the ground or a building on the ground. A cable 322 is provided on the ground spike 323, and the cable 322 is transmission-connected to pulley 1 320 and pulley 2 321. Pulley 1 320 and pulley 2 321 are respectively rotatably connected to the rising shaft 319 and the fixed shaft 328. The fixed shaft 328 is rotatably connected to the stand 2, and the rising shaft 319 is slidably connected to the stand 2. The two ends of the rising shaft 319 are rotatably connected to the locking rod 318, and the top of the locking rod 318 is rotatably connected to the sliding shaft 308. When the sliding shaft 308 is controlled to move laterally by the rotation of centrifugal force, it will drive the locking rod 318. Since the sliding shaft 308 is symmetrically arranged, the lateral movement of the sliding shaft 308 will provide an upward pulling force to the rising shaft 319 through the two locking rods 318. When the rising shaft 319 is subjected to an upward thrust, the thrust will be transmitted to the cable 322. The cable 322 forms a V-shaped loop state. At this time, the surface of the pulley 2 321 will be subjected to the downward tension of the cable 322. When the pulley 1 320 in the middle position is subjected to an upward thrust, it will reverse the thrust to the pulley 2 321, and then transmit it to the stand 2 and base 1 through the fixed shaft 328. Ultimately, the entire base 1 and stand can be firmly pressed against the ground, thereby improving the firmness of the entire photovoltaic support and its overall wind resistance and compressive strength.

[0036] It's worth noting that the ground spike 323 includes a pin 3232, fixedly connected to a pull rod 3231, which is rotatably connected to a pulley 3233. The cable 322 is rotatably connected to the surface of pulley 3233. This technical solution utilizes a pre-buried structure, with the ground spike 323 inserted into the ground for fixation, thereby securing points on both sides. The ground spike 323 can also be directly installed on large structures, such as utility poles or buildings. The specific installation method depends on the surrounding installation environment of the photovoltaic panel 41 and is not specifically limited.

[0037] It is worth noting that it also includes a pressure display component; the pressure display component includes a central gear 324, the axis of the central gear 324 is rotatably connected to a support frame 325 through a connecting rod, the support frame 325 is fixed on the stand 2, a display panel 326 is fixedly connected to the support frame 325, the display panel 326 is rotatably connected to the pointer 327, the pointer 327 is fixedly connected to the central gear 324 through a connecting rod, and the two sliding square shafts 303 are rotatably connected to the linkage plate 329, and the two linkage plates 329 are engaged with the upper and lower surfaces of the central gear 324. The pressure display component is set to provide the user with visual display. When the sliding square shaft 303 slides and opens due to centrifugal force, it will drive the synchronous movement of the linkage plate 329. Because the linkage plate 329 is rotationally connected to the sliding square shaft 303, the rotation of the sliding square shaft 303 will not drive the linkage plate 329 to rotate, and then drive it to move laterally. After the linkage plate 329 moves laterally, it will synchronously drive the rotation of the center gear 324, thereby controlling the synchronous sliding of the two sliding square shafts 303 and the synchronous sliding distance, thereby avoiding the imbalance of the locking tension on both sides caused by the different sliding distances of the two sliding square shafts 303, and under the rotation condition of the center gear 324, the pointer 327 can also be driven to rotate through the connecting rod. The user can determine the size of the locking force borne by the entire photovoltaic bracket at this time based on the rotation angle of the pointer 327.

[0038] It is worth mentioning that there are two sets of spikes 323, two in a group, which are respectively arranged on the left and right sides of the base 1. The two sets of spikes 323 are symmetrically arranged about the center line of the base 1. The symmetrical arrangement of the spikes 323 can provide symmetrical pressing force between the base 1 and the stand 2, avoiding the tilting of the base 1 caused by pressure imbalance.

[0039] Working principle: first, when the entire photovoltaic bracket is in use, if the natural wind is generated outside, the blades 301 will be blown directly to rotate, and when the blades 301 are rotating, the two centrifugal balls 304 will be driven to rotate synchronously. After the centrifugal rod 305 is connected to the hollow shaft 302, the centrifugal force will be gradually used to drive the two centrifugal rods 305 to open. When the centrifugal rod 305 is open, it will rotate on the hollow shaft 302 at an angle, and then drive the rotation of the fixed gear 306, and then drive the sliding square shaft 303 to slide horizontally inside the hollow shaft 302, because at this time the sliding square shaft 303 and the hollow shaft are connected. The shaft 302 rotates due to the rotation of the blades 301. The bearing ring 309, through its rotational connection, prevents the sliding shaft 308 from rotating. This utilizes the lateral thrust of the sliding square shaft 303. As the sliding shaft 308 moves laterally, it controls the sliding pin 316 to slide within the inclined slot 317 on the counterweight frame 310. This lateral sliding principle provides an upward thrust to the counterweight frame 310. This upward thrust from the counterweight frame 310 pulls the tensioning cables 44 connected to the left and right sides upward. The tensioning cables 44 are serially connected to the frame 42, thus providing tension to the frame 42. Furthermore, as wind speed increases, the rotation speed of the hollow shaft 302 increases, and the centrifugal force exerted on the centrifugal balls 304 increases. This translates into a greater lateral thrust, which in turn increases the tension on the frame 42, further stabilizing the photovoltaic panel 41. This in turn enhances the overall wind resistance of the photovoltaic frame. However, different structures have certain limits in terms of material and structural strength. Therefore, considering the strength of the material and the structure of the frame 42, the inclined slot 317 is set to an open structure. When the sliding pin 316 moves horizontally to the limit position, it will disengage from the right opening position of the inclined slot 317, and then the counterweight frame 310 will lose the upward thrust and the engaged state of the sliding pin 316. At this time, the counterweight frame 310 will sink under its own gravity. After the counterweight frame 310 sinks, it will drive the support 313 to move downward through the connection between the threaded sleeve 314 and the threaded rod 315, and then drive the two horizontal tooth plates 43 to move relative to each other through the rotation connection of the two support rods 312. Then, the meshing transmission of the gears and the tooth plates drives multiple small gears 45 to rotate, and then drives multiple frames 42 to "lie flat" and achieve automatic flatness. Because in the flat state, the wind resistance of natural wind blowing on the frame 42 will be reduced, thereby maximizing the safety protection of the photovoltaic panel 41 and avoiding damage to the photovoltaic panel 41 caused by excessive wind resistance. Therefore, the entire device is provided with a safety structure, which can automatically protect and lay the photovoltaic panel 41 flat when the photovoltaic frame is under the extreme condition.A small spring is provided on the left side of the transverse tooth plate 43, and the small spring is provided inside the base 1. The purpose of the small spring is to provide a rightward thrust for the transverse tooth plate 43 to avoid the two support rods 312 from getting stuck when the counterweight frame 310 moves. In addition, the setting of the small spring can provide a lateral buffer for the lateral movement of the transverse tooth plate 43 when the counterweight frame 310 sinks. Therefore, the frame body 42 will not "hit" the base 1 at this time, and there is a flat buffer to protect the photovoltaic panel 41 from damage from the side. In addition, the entire photovoltaic rack is also provided with a second locking device, and the second locking device is used to lock the installation position of the base 1. In the initial installation of the photovoltaic bracket, four ground spikes 323 are used for tensioning and installation. Two ground spikes 323 are provided on the left and right sides of the base 1, and the ground spikes 323 are directly inserted into the ground and fixed using the barbed structure, or the ground spikes 323 are directly installed on large buildings, such as telephone poles and houses. The specific installation is selected according to the surrounding installation environment of the photovoltaic panel 41, and there is no specific limitation. When natural wind is generated, the rotation of the centrifugal force is also used to control the horizontal movement of the sliding shaft 308, which will drive the pulling of the locking rod 318, and since the sliding shaft 308 is symmetrically arranged, the sliding shaft 308 moves horizontally, which will be The two locking rods 318 provide an upward pulling force for the rising shaft 319. When the rising shaft 319 is subjected to an upward thrust, the thrust will be transmitted to the cable 322, and the cable 322 is in a V-shaped loop state. At this time, the surface of the pulley 2 321 will be subjected to the downward tension of the cable 322. Because the two ends of the cable 322 are fixed by the ground spikes 323, the positions of the two pulleys 3233 will be fixed. When the pulley 1 320 in the middle position is subjected to an upward thrust, the thrust will be transmitted in the opposite direction to the pulley 2 321, and then transmitted to the stand 2 and the base 1 through the fixed shaft 328. Finally, the entire base 1 and the stand can be firmly pressed on the ground, thereby improving the firmness of the entire photovoltaic bracket and improving its overall wind resistance and compressive strength.
