Description

Technical Field

[0001] This invention relates to the field of photovoltaic regulation and protection technology, and in particular to an adaptive adjustment device for a wind-pressure resistant photovoltaic support. Background Technology

[0002] Photovoltaic brackets are the basic structures used to support and fix photovoltaic modules in a photovoltaic power generation system. Their main function is to provide a stable installation angle and spatial position for photovoltaic modules to meet the requirements of different regional irradiance conditions and power generation efficiency. They are usually installed in complex environments such as the ground, power station roof or mountains, and need to be exposed to outdoor conditions for a long time to withstand various external forces such as wind load, snow load and self-weight.

[0003] Based on the actual usage environment of photovoltaic modules, conventional photovoltaic brackets need to provide high-strength support and connection for the photovoltaic modules. The brackets on the market can generally be divided into two categories. One is the direct-fixed type, which is mostly fixed by bolts. The photovoltaic panels and brackets cannot be adjusted. Its advantages are stability and ease of maintenance. The other type is a hinged connection method, which uses transmission components to drive the photovoltaic panels to make appropriate angle adjustments. Its advantage is that it can increase the contact area between the photovoltaic panels and the light at different times, thereby improving the energy collection rate.

[0004] Regarding the latter type of photovoltaic panel connection method, the photovoltaic brackets used for this type of photovoltaic panel are extremely prone to damage at the hinges and transmission units under strong winds. This is because, under the action of wind pressure, the atmospheric pressure in the space above and below the photovoltaic panel is uneven (photovoltaic panels are mostly arranged in an array, and they are relatively close to each other). The hinged connection method has more serious drawbacks in this environment, causing the photovoltaic modules to shake beyond the limit, and even causing breakage and damage between the hinges and the transmission units. At the same time, a search revealed that publication number CN116094430A discloses a wind-resistant photovoltaic system with a limit and its adjustable bracket assembly. This patent document also objectively reflects the actual problems encountered in the use of the aforementioned second type of photovoltaic bracket.

[0005] Therefore, how to provide an adaptive adjustment device for wind-pressure resistant photovoltaic supports is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide an adaptive adjustment device for wind-pressure resistant photovoltaic support. This invention provides a good buffering effect for photovoltaic panels and adaptively judges and handles the wind environment, thereby preventing damage to the support connection and transmission unit.

[0007] According to an embodiment of the present invention, a wind-pressure resistant photovoltaic support adaptive adjustment device includes a photovoltaic panel movably mounted above a sheet pile assembly via a support assembly and two sets of side sub-frames. The sheet pile assembly is fixedly connected to a bottom pile at its bottom. The sheet pile assembly includes a combined frame plate and two sets of toothed rods. The two sets of toothed rods are respectively engaged with two sides of a transmission toothed shaft rotatably disposed inside the combined frame plate. The top of the toothed rods is elastically telescopically connected to a connecting seat. The connecting seat is rotatably connected to the bottom end of the side sub-frames. The top end of the side sub-frames is rotatably connected to the bottom of the photovoltaic panel.

[0008] The transmission gear shaft has a single-sided shaft that moves through the combined frame plate and is equipped with a drive mechanism and a monitoring unit. The drive mechanism includes two sets of toothed belts and an elastic belt. The shaft of the transmission gear shaft is fixedly connected to the driven pulley. One set of toothed belts engages with the driven pulley through an anti-detachment block fixed on the surface of the combined frame plate. The other set of toothed belts engages with the transmission pulley inside the bottom pile. The two ends of the two sets of toothed belts are elastically connected together by an elastic belt.

[0009] The monitoring unit includes a rotating disk and two sets of conductive protrusions. The two sets of conductive protrusions are electrically connected through a potential conduction component inside the rotating disk. The rotating disk is fixed to one side of the transmission gear shaft.

[0010] Furthermore, the support assembly includes a slide rail plate fixed to the bottom of the main frame, the top of the main frame is rotatably set at the center of the bottom of the photovoltaic panel via an ear seat, the slide rail plate is vertically limited and slides above the combined frame plate, and the bottom of the slide rail plate is elastically connected to the combined frame plate via a support spring.

[0011] Furthermore, a slider is fixed on one side of the top of the connecting seat, which slides vertically to limit the sliding of the slide rail plate, and the sliders corresponding to the two sets of connecting seats do not interfere with each other when sliding on the surface of the slide rail plate.

[0012] Furthermore, the shaft of the transmission pulley is fixed to the output end of the motor component, and the toothed belt and the transmission pulley form a wrap angle. Slide tracks are opened through the bottom pile on both sides near the toothed belt.

[0013] Furthermore, a cavity is opened near the top of the bottom pile slide, and a damping plate is vertically slidably installed in the cavity. The top of the damping plate is fixed to the output end of the electromagnetic actuator, and the bottom of the damping plate has the same inclination angle as the slide.

[0014] Furthermore, the toothed belt is positioned on both sides of the bottom pile and passes around the guide pulleys, with the guide pulleys having an adjustable swing angle on both sides of the bottom pile.

[0015] Furthermore, four sets of recessed openings are equidistantly arranged on the outer ring surface of the rotating disk, and the conductive protrusions are elastically set inside the outer protective shell by a reset spring. The outer protective shell is fixed to the surface of the combined frame plate, and the two sets of conductive protrusions are arranged opposite each other.

[0016] Furthermore, the potential conduction component includes a conductive metal ring and four sets of conductive slide cylinders, with the positions of the four sets of conductive slide cylinders corresponding to four sets of recesses. The potential conduction component also includes a conductive slide rod, which is slidably disposed inside the conductive slide cylinder below. An elastic pad is fitted on the surface of the conductive slide rod, and the conductive slide rod is elastically disposed on the top of the conductive slide cylinder through the elastic pad.

[0017] Furthermore, the two sets of conductive protrusions are electrically connected to the control unit inside the bottom pile via wires. The control unit is electrically connected to control the opening and closing of the motor components and the electromagnetic actuator, respectively.

[0018] The beneficial effects of this invention are:

[0019] The elastic support structure of the sheet pile assembly and the support assembly of the present invention can provide a better expansion and contraction buffer effect between the photovoltaic panel and the sheet pile assembly when the photovoltaic panel is kept horizontal, and prevent damage to the side sub-frame and support assembly caused by hard pulling. Compared with the prior art, it further optimizes the connection stability while ensuring the transmission connection effect and improves the service life of the connector.

[0020] This invention, through its driving mechanism, enables the transmission gear shaft to rotate when the photovoltaic panel is deflected by wind. This rotation, via the driven pulley, directly drives a single set of toothed belts to move in one direction, thereby stretching and deforming the elastic belt. Meanwhile, the toothed belt connected below the elastic belt is pressed down by the damping plate, allowing the elastic belt to reset under its own elasticity. This, in turn, enables the photovoltaic panel to reset, satisfying the self-resetting operation of the photovoltaic panel under appropriate wind conditions.

[0021] This invention uses a monitoring unit to rotate the rotating disk simultaneously with the transmission gear shaft. This causes the inner concave opening to squeeze the conductive protrusions out of the rotating disk. The actual on / off time is used to determine the external environment and the actual posture of the photovoltaic panel. When two sets of conductive protrusions are inserted into two other sets of inner concave openings, it indicates that the wind force is too strong. At this time, the electromagnetic actuator can release the pressure plate from the toothed belt, and the elastic band will elastically reset and pull the lower toothed belt to move, thus realizing the calibration operation.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] refer to Figures 1-8The assembly includes a photovoltaic panel 1 movably mounted above a sheet pile assembly 3 via a support assembly 4 and two sets of side sub-frames 2. The photovoltaic panel 1 and the sheet pile assembly 3 are directly and movably mounted above the sheet pile assembly 3 through the combined action of a single support assembly 4 and two sets of side sub-frames 2, satisfying the swing adjustment capability in the prior art. The bottom of the sheet pile assembly 3 is fixedly connected to a bottom pile 5, which is directly fixed to the ground to ensure actual stability. The sheet pile assembly 3 includes a combined frame plate 31 and two sets of toothed rods 32. The combined frame plate 31 is composed of two sets of opposing plates, which are directly fixed to each other with bolts after assembly. The two sets of toothed rods 32 respectively mesh with the two sides of a transmission gear shaft 39 rotatably mounted inside the combined frame plate 31. Therefore, when the transmission gear shaft 39 rotates, it can drive the two sets of toothed rods 32 to move in different transmission directions. In fact, one set of toothed rods 32 moves upward, while the other set of toothed rods 32 moves downward. 2. Downward movement, simultaneously, the top of the toothed rod 32 is elastically telescopically connected to the connecting seat 33. The connecting seat 33 is rotatably connected to the bottom of the side sub-frame 2, and the top of the side sub-frame 2 is rotatably connected to the bottom of the photovoltaic panel 1. Thus, when a single set of toothed rods 32 moves upward under the transmission of the transmission gear shaft 39, it can elastically push the connecting seat 33 to move upward synchronously. The effect of the hinge between the connecting seat 33 and the bottom of the side sub-frame 2 causes the connecting seat 33 to push the bottom of the side sub-frame 2 synchronously. The top of the side sub-frame 2 is hinged to the photovoltaic panel 1. In actual assembly, the side sub-frame 2 presents a certain angle. Therefore, the toothed rod 32 on one side pushes the side sub-frame 2 to drive one side of the photovoltaic panel 1 to move upward, while the toothed rod 32 on the other side will drive the other side of the photovoltaic panel 1 to move downward through the side sub-frame 2. At the same time, under the limitation of the bracket assembly 4 on the center position of the bottom of the photovoltaic panel 1, the photovoltaic panel 1 as a whole can complete the flip adjustment effect and change the actual angle orientation of the photovoltaic panel 1.

[0037] The transmission gear shaft 39 is actually a fixed combination of a gear and a shaft. The shaft is directly rotatably connected to the combined frame plate 31. One side of the transmission gear shaft 39 extends through the combined frame plate 31 and is equipped with a drive mechanism 6 and a monitoring unit 7. When the drive mechanism 6 receives a transmission effect, it can drive the transmission gear shaft 39 to rotate within the combined frame plate 31, thus achieving the adjustment of the photovoltaic panel 1. The drive mechanism 6 includes two sets of toothed belts 61 and an elastic belt 62. The shaft of the transmission gear shaft 39 is fixedly connected to the driven pulley 63. Each set of toothed belts 61... The anti-detachment block 64 fixed on the surface of the combined frame plate 31 engages with the driven pulley 63 for transmission. The main function of the anti-detachment block 64 is to prevent the single set of toothed belts 61 from disengaging from the driven pulley 63, ensuring the actual engagement transmission effect. The other set of toothed belts 61 engages with the transmission pulley 65 inside the bottom pile 5. Therefore, the transmission pulley 65 drives the single set of toothed belts 61 for transmission. Under the elastic action of the elastic belt 62, it pulls the toothed belts 61 above that are engaged with the driven pulley 63 to achieve synchronous transmission, thereby realizing the rotation of the subsequent transmission gear shaft 39.

[0038] The two ends of the two sets of toothed belts 61 are elastically connected together by elastic bands 62. The two sets of toothed belts 61 and the two sets of elastic bands 62 constitute a single strip-shaped component, which is connected end to end and staggered. Therefore, no matter which direction the two sets of toothed belts 61 move, they will pull the elastic band 62 on one side to stretch elastically. The monitoring unit 7 includes a rotating disk 71 and two sets of conductive protrusions 74. The two sets of conductive protrusions 74 are electrically connected through the potential conduction component 72 inside the rotating disk 71. That is, under normal circumstances, the conductive protrusions 74 are connected through the potential conduction component 72. 2. Electrical connection ensures the transmission of electrical signals. However, the rotating disk 71 is fixed to the shaft on one side of the transmission gear 39. Therefore, when the photovoltaic panel 1 is affected by wind and deflects, the transmission gear 39 rotates synchronously under the transmission force of the gear members 32 on both sides. The rotation effect will drive the rotating disk 71 to rotate. Simultaneously, the potential conduction component 72 rotates. However, the two sets of conductive protrusions 74 are set on the combined frame plate 31. Therefore, at this time, the potential conduction component 72 will disengage from the conductive protrusions 74, thereby interrupting the transmission of electrical signals.

[0039] The bottom of the connecting seat 33 slides on the toothed rod 32 via the sliding shaft 35. Two sets of movable cavities 38 are opened in the slide of the toothed rod 32 near the sliding shaft 35. The sliding shaft 35 is fixedly connected to the anti-convex ring 36 in the area of ​​the movable cavity 38. Compression springs 37 are respectively sleeved at the upper and lower ends of the anti-convex ring 36. When the connecting seat 33 and the toothed rod 32 extend and retract, the anti-convex ring 36 and the inner wall of the movable cavity 38 will squeeze and stretch the compression springs 37 at the corresponding positions, so that the connecting seat 33 and the toothed rod 32 will undergo elastic extension and retraction. This elastic extension and retraction mainly meets the requirement that the photovoltaic panel 1 can cooperate with the bracket assembly 4 to achieve a slight displacement adjustment after being affected by wind, and prevent excessive stress from damaging the connecting parts.

[0040] refer to Figure 2 and Figure 4 The support assembly 4 includes a slide rail plate 42 fixed to the bottom of the main frame 41. The top of the main frame 41 is rotatably set at the center of the bottom of the photovoltaic panel 1 through an ear seat, providing the main support point for the photovoltaic panel 1 and ensuring the center position, so that the side sub-frame 2 can better control and deform the photovoltaic panel 1. The slide rail plate 42 is vertically limited and slides above the combined frame plate 31. The bottom of the slide rail plate 42 is elastically connected to the combined frame plate 31 through a support spring 43. Therefore, a corresponding groove for the slide rail plate 42 to slide needs to be opened above the combined frame plate 31. The bottom of the slide rail plate 42 and the combined frame plate 31 are elastically connected through the support spring 43. Therefore, when the photovoltaic panel 1 is subjected to upward or downward pushing or pulling forces, the support spring 43 can ensure the elastic deformation effect and meet a certain degree of buffering and limiting.

[0041] The top side of the connecting seat 33 is fixed with a slider 34 that slides vertically to the slide rail plate 42, ensuring the stability of the connecting seat 33. Under normal circumstances, when the side sub-frame 2 pushes the connecting seat 33, the sliding shaft 35 below the connecting seat 33 will slide and block the toothed rod 32. However, the limiting sliding between the slider 34 and the slide rail plate 42 allows the upward conversion and transmission of force, thus making the movement of the toothed rod 32 smoother. Moreover, the sliders 34 corresponding to the two sets of connecting seats 33 do not interfere with each other when sliding on the surface of the slide rail plate 42. This mainly indicates that the two sets of sliders 34 are in different vertical slides.

[0042] Example 1: When the photovoltaic panel 1 is in a horizontal state, due to the influence of the actual array setting, the wind speed above the photovoltaic panel 1 is fast and the air pressure is low, while the air pressure below is high. Therefore, the photovoltaic panel 1 is subjected to air pressure and has an upward movement tendency. At this time, the photovoltaic panel 1 pulls the support spring 43 connected to the combined frame plate 31 through the main frame 41 and the slide rail plate 42 below. Simultaneously, the two sides below the photovoltaic panel 1 pull the side sub-frame 2 to drive the slide shaft 35 below the connecting seat 33 to move upward in the cavity 38. At the same time, the anti-convex ring 36 on the surface of the slide shaft 35 squeezes the compression spring 37 to achieve an elastic buffering effect, which protects the connection between the lower part of the toothed rod 32 and the transmission toothed shaft 39 to the greatest extent and prevents damage caused by force.

[0043] refer to Figure 3 , Figure 5 , Figure 7 and Figure 8 The motor component 67 is directly fixed inside the bottom pile 5. The motor component 67 can be connected to the conductive plug 74 through the control system. The shaft of the transmission pulley 65 is fixed to the output end of the motor component 67. The toothed belt 61 and the transmission pulley 65 form a wrap angle, so that the transmission pulley 65 rotates after the motor component 67 is started. Under a certain wrap angle engagement, the toothed belt 61 below moves in one direction. At the same time, slide rails are opened through the bottom pile 5 near the toothed belt 61 on both sides. One side of the toothed belt 61 can extend outward with the slide rail to compensate for the elastic stretching deformation of the elastic band 62.

[0044] Furthermore, a cavity is actually opened above the slide rail near the bottom pile 5. A damping plate 68 is vertically slidably installed in the cavity. The top of the damping plate 68 is fixed to the output end of the electromagnetic actuator 69, and the bottom of the damping plate 68 is at the same angle as the slide rail. Therefore, when the electromagnetic actuator 69 is started under control, it can drive the damping plate 68 to slide vertically in the cavity inside the bottom pile 5 until the bottom of the damping plate 68 presses against the top of the toothed belt 61 in the slide rail. This restricts the position of the toothed belt 61 on both sides of the transmission pulley 65, preventing the toothed belt 61 from pulling the transmission pulley 65 to rotate under the influence of wind and causing damage to the motor components 67. The positions on both sides of the bottom pile 5 are respectively bypassed by guide pulleys 66. The guide pulleys 66 are set on both sides of the bottom pile 5 with adjustable swing angle. With the adjustable operation of the guide pulleys 66, the overall preload of the elastic belt 62 and the toothed belt 61 can be adjusted, which is suitable for use in different wind environments.

[0045] Example 2: During normal use, the electromagnetic actuator 69 presses the two sides of the toothed belt 61 with the resistive pressure plate 68. When the photovoltaic panel 1 is deflected due to the wind, the transmission gear shaft 39 can drive the driven pulley 63 to rotate. At this time, under the restriction of the anti-detachment block 64, the driven pulley 63 engages with the toothed belt 61 above and moves in one direction. At this time, the elastic belt 62 on one side is stretched and undergoes elastic deformation, while the elastic belt 62 on the other side contracts under the action of elasticity. When the wind decreases, the elastic action of the elastic belt 62 can realize the elastic rotation and reset of the transmission gear shaft 39, thereby realizing the reset of the photovoltaic panel 1 to the initial angle.

[0046] refer to Figure 5 , Figure 6 and Figure 8 The outer ring surface of the rotating disk 71 has four sets of recessed openings 73 arranged at equal intervals and angles. The recessed openings 73 are recessed towards the center of the conductive protrusion 74 and match the shape of the end of the conductive protrusion 74. The conductive protrusion 74 is elastically set in the outer protective shell 76 by the return spring 75. The outer protective shell 76 is fixed to the surface of the combined frame plate 31. Therefore, under normal circumstances, the port of the conductive protrusion 74 is elastically inserted into the recessed opening 73 by the return spring 75. When the two sets of conductive protrusions 74 are arranged opposite each other, the two sets of conductive protrusions 74 are electrically connected, that is, the conductive protrusion 74 is inserted into the recessed opening 73 and contacts the potential conduction component 72.

[0047] The potential conduction component 72 includes a conductive metal ring 721 and four sets of conductive slide cylinders 722. The positions of the four sets of conductive slide cylinders 722 correspond to four sets of recesses 73, that is, the conductive slide cylinders 722 and the conductive metal ring 721 are all fixed inside the rotating disk 71. The conductive slide cylinders 722 are aligned and connected with the recesses 73. The potential conduction component 72 also includes a conductive slide rod 724. The conductive slide rod 724 is slidably disposed inside the conductive slide cylinder 722. An elastic pad 723 is sleeved on the surface of the conductive slide rod 724. The conductive slide rod 724 is elastically supported by the elastic pad 723. Located at the top of the conductive slide cylinder 722, the top end of the conductive slide rod 724 is normally in contact with the port of the conductive protrusion 74. Under the elastic action of the elastic pad 723, the conductive slide rod 724 always maintains an outward limiting and resisting effect, ensuring that the conductive protrusion 74 can normally communicate with another set of conductive protrusions 74 through the potential conduction component 72 under slight displacement. The ends of the two sets of conductive protrusions 74 are electrically connected to the control unit inside the bottom pile 5 through wires. The control unit is electrically connected to control the opening and closing of the motor component 67 and the electromagnetic actuator 69 respectively.

[0048] Example 3 can be divided into three cases:

[0049] 1. When the wind force is small, the deflection displacement of the photovoltaic panel 1 will cause the rotating disk 71 to rotate by a small angle. At this time, under the elastic action of the elastic pad 723 between the conductive slide rod 724 and the conductive slide cylinder 722, the conductive slide rod 724 always keeps in contact with the end of the conductive protrusion 74. That is, the slight rotation of the rotating disk 71 still realizes the signal connection between the two sets of conductive protrusions 74. The motor 67 and the electromagnetic actuator 69 do not make any compensation.

[0050] Second, when the wind force is strong, the photovoltaic panel 1 is subjected to greater sway. After the rotating disk 71 rotates, the concave opening 73 squeezes the conductive protrusion 74 completely out of the concave opening 73, causing the signal between the two sets of conductive protrusions 74 to be interrupted. Then, under the elastic action of the elastic band 62, the rotating disk 71 is driven to rotate and reset. The conductive protrusion 74 re-establishes signal conduction through the conductive slide rod 724 and the conductive slide cylinder 722. The signal processing system can judge the actual external environment based on the on / off time.

[0051] Third, when encountering extreme wind conditions, the rotating disk 71 is driven to rotate to 90 degrees. At this time, the photovoltaic panel 1 is in a horizontal state. After the rotating disk 71 rotates 90 degrees, the two sets of conductive protrusions 74 will be inserted into the other two sets of recesses 73. At this time, the signal is connected again through the potential conduction component 72. By setting different resistances of the potential conduction component 72 or directly setting two sets of conductive metal rings 721 structures, different signal transmissions can be achieved. The signal processing system controls the electromagnetic actuator 69 to release the restriction on the toothed belt 61 in real time. At the same time, the motor component 67 starts to drive the transmission pulley 65 to rotate, realizing the compensation operation of the toothed belt 61 and the elastic belt 62, thereby realizing the elastic calibration of the elastic belt 62 in this mode.

[0052] Working principle: When the photovoltaic panel 1 tilts due to wind, if it was originally tilted, the photovoltaic panel 1 will control the connecting seat 33 to move in a counter-movement through the side sub-frame 2. Under the action of the compression spring 37, it completes a stage of elastic buffering effect. Meanwhile, the toothed rod 32 is simultaneously forced to drive the transmission gear shaft 39 to rotate. On one hand, the driven pulley 63 is driven to rotate by the transmission gear shaft 39, and the toothed belt 61 pulls the elastic belt 62 to deform elastically and completes the reset under the action of elasticity. Meanwhile, the electromagnetic actuator 69 presses the bottom of another set of toothed belts 61 through the blocking pressure plate 68, so that the transmission pulley 65 will not The rotation then occurs, effectively protecting the motor components 67. On the other hand, the monitoring unit 7 directly monitors the amount of rotation to determine the actual external environment and the actual posture of the photovoltaic panel 1. If the photovoltaic panel 1 is in a horizontal state, its horizontal posture can adapt to windy weather to the greatest extent. The airflow above the photovoltaic panel 1 is fast, and the photovoltaic panel 1 moves upward as a whole. The movement effect directly drives the anti-convex ring 36 to compress the compression spring 37. At the same time, the tension support spring 43 below the slide rail plate 42 is stretched, achieving a better tensioning effect of the combined frame plate 31 on the photovoltaic panel 1 and preventing hard damage to the connection end.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
