Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, and specifically to an angle-adjustable photovoltaic mounting bracket and its usage method. Background Technology

[0002] Photovoltaic panels, also known as solar panels or PV panels, are devices that directly convert sunlight into electrical energy. They mainly consist of multiple solar cells connected in series and / or parallel, and these cells are typically made of semiconductor materials such as silicon. PV panels should be installed in locations with ample sunlight, avoiding shading. Modern intelligent tracking systems can automatically adjust the angle of the PV panels based on the sun's position, further increasing energy output. The support structure is a crucial component for supporting the PV panels; it not only needs to ensure the safety and stability of the panels but also needs to facilitate installation and maintenance.

[0003] Current intelligent tracking photovoltaic (PV) mounting systems typically only allow for uniform vertical adjustment of multiple rows of PV modules, failing to meet the need for horizontal angular adjustment of the entire PV array along its vertical axis to adapt to changes in the sun's position. While a few devices on the market can achieve both vertical and horizontal adjustments, the installation and adjustment process for these devices in the horizontal direction along the vertical axis is complex, increasing both initial installation difficulty and subsequent maintenance costs and complexity. More importantly, to achieve independent rotation of each PV module along the vertical axis, a separate drive motor is often required for each panel, significantly increasing system costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an angle-adjustable photovoltaic mounting bracket and its usage method, solving the problem that existing photovoltaic mounting systems can only uniformly adjust multiple rows of photovoltaic modules in the vertical direction, and cannot adjust the angle of the photovoltaic array in the horizontal direction of the vertical axis.

[0005] The technical solution to achieve the above objectives is:

[0006] This invention provides an angle-adjustable photovoltaic mounting bracket, comprising: a plurality of first support rods vertically fixed to the ground; a mounting beam for mounting photovoltaic panels, rotatably disposed at the upper end of the first support rods around its own axis, so that the photovoltaic panels rotate synchronously with the mounting beam, thereby adjusting the orientation of the photovoltaic panels; a drive mechanism disposed on the ground and connected to the mounting beam for driving the mounting beam to rotate; a rotating rod disposed inside the mounting beam and rotatably disposed around its own axis, the rotating rod also rotating around the axis of the mounting beam in a circular motion, the photovoltaic panels being rotatably mounted on the mounting beam with the rotation direction perpendicular to the surface of the photovoltaic panels, the rotating rod being drively connected to the photovoltaic panels so that the rotating rod drives the photovoltaic panels to rotate relative to the mounting beam by rotating around its own axis; and a gear mechanism disposed on the ground on one side of the mounting beam and connected to the rotating rod, for causing the rotating rod to rotate around its own axis while the mounting beam rotates.

[0007] Furthermore, the gear mechanism includes: a second support rod, vertically fixed to the ground; an internal gear ring fixed to the upper end of the second support rod, the internal gear ring being coaxially arranged with the crossbeam; a driven gear, fixed to one end of the rotating rod and meshing with the internal gear ring, the driven gear being smaller than the internal gear ring; a plurality of third support rods are provided inside the mounting beam; the rotating rod is rotatable around its own axis and is mounted on the third support rods; the rotating rod and the mounting beam are not on the same axis, so that when the rotating rod rotates around the axis of the mounting beam, the meshing of the driven gear and the internal gear ring enables the rotating rod to rotate around its own axis.

[0008] The mounting beam is rotatably provided with several support components. The photovoltaic panel is fixed on the support components, and a connecting component is provided between the rotating rod and the support components for the rotating rod to drive the support components to rotate, thereby driving the photovoltaic panel to rotate.

[0009] Furthermore, the mounting beam is provided with a number of threaded holes spaced apart, and a mounting sleeve is threaded into the threaded holes. The support assembly is rotatably mounted on the mounting sleeve. The support assembly includes a locking block and a support rod plate. The support plate is rotatably mounted on the mounting sleeve. The locking block is U-shaped and fixed to the support plate. The locking block is provided with a mounting frame, and the photovoltaic panel is mounted on the mounting frame.

[0010] Furthermore, the outer surface of the mounting sleeve is provided with a first thread and a second thread. The first thread is located below the second thread and engages with the internal thread of the screw hole. A fixing nut is fitted on the mounting sleeve and engages with the second thread. The first thread and the second thread have opposite directions of rotation, thereby preventing the mounting sleeve from falling out of the screw hole when the fixing nut is tightened in the mounting sleeve.

[0011] Furthermore, the mounting sleeve is a hollow cylindrical shape, and the connecting assembly includes: a slider disposed inside the mounting sleeve, the bottom of the slider having a groove; a transmission rod rotatably disposed in the groove, a worm gear fixed on the transmission rod, and a worm meshing with the worm gear on the rotating rod; and a mounting rod, the upper end of which is fixedly connected to the support assembly, the slider having a through hole for the lower end of the mounting rod to extend into the groove, the lower end of the mounting rod being fixedly provided with a second bevel gear, and the transmission rod having a first bevel gear meshing with the second bevel gear.

[0012] Furthermore, the inner wall of the mounting sleeve is provided with several grooves, and the outer surface of the slider is provided with a protrusion, which is slidably disposed in the groove; a ring-shaped mounting plate is fixed on the inner wall of the mounting sleeve and located above the slider, and a spring is provided between the slider and the mounting plate.

[0013] Furthermore, it also includes a crossbeam located below the mounting beam. The crossbeam is perpendicular to the mounting beam and is connected to it by a connecting rod. The upper end of the connecting rod is fixed to the mounting beam, and the lower end is hinged to the crossbeam. The crossbeam is movable to drive the mounting beam to rotate around its own central axis via the connecting rod. The drive mechanism is connected to the crossbeam to drive the crossbeam to move.

[0014] Furthermore, the drive mechanism includes: a U-shaped frame fixed to the ground, a rotating frame hinged inside the U-shaped frame, a servo motor fixed on the rotating frame; a mounting component and a screw, the mounting component being fixed to the servo motor, one end of the screw being hinged to the crossbeam, and the other end passing through the mounting component, the mounting component having two meshing gears, one gear being connected to the output shaft of the servo motor, and the other gear being sleeved on the screw and threadedly connected to the screw.

[0015] Furthermore, the mounting beam has multiple beams, the first support rods are spaced out in multiple rows, and all the mounting beams are connected to the drive mechanism.

[0016] The present invention also provides a method for using an angle-adjustable photovoltaic mounting bracket, specifically including the following steps: providing the photovoltaic mounting bracket as described above, and installing the photovoltaic mounting bracket at the designed position; activating the drive mechanism, causing the drive mechanism to drive the mounting beam to rotate according to the angle of the sun, thereby driving the photovoltaic panel to rotate synchronously with the mounting beam, so as to adjust the orientation of the photovoltaic panel so that the top surface of the photovoltaic panel faces the sun; while the mounting beam rotates, the rotating rod rotates around its own axis through a gear mechanism, thereby causing the rotating rod to drive the photovoltaic panel to rotate relative to the mounting beam.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By setting up a self-rotating mounting beam and a rotating rod inside the mounting beam, the rotating rod is connected to the photovoltaic panel drive. The mounting beam drives the photovoltaic panel to rotate synchronously by rotating, so as to adjust the orientation of the photovoltaic panel. When rotating, it drives the rotating rod to move in a circle around the axis of the mounting beam. By cooperating with the gear mechanism, the rotating rod can rotate around its own axis, so as to drive the photovoltaic panel to rotate relative to the mounting beam.

[0019] By setting up an installation sleeve with first and second threads in opposite directions, the installation sleeve is threadedly connected to the installation beam and secured with a fixing nut. The opposite threads prevent the installation sleeve from falling off and also effectively prevent loosening of the installation sleeve due to long-term use, thus enhancing the safety and reliability of the system.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] See Figure 1 This invention provides an angle-adjustable photovoltaic mounting bracket and its usage method, solving the problem that existing photovoltaic mounting systems can only uniformly adjust multiple rows of photovoltaic modules in the vertical direction, and cannot adjust the angle of the photovoltaic array in the horizontal direction along the vertical axis. By setting a rotatable mounting beam and a rotating rod within the mounting beam, the rotating rod is driven to the photovoltaic panel. The mounting beam rotates, causing the photovoltaic panel to rotate synchronously to adjust its orientation. During rotation, the rotating rod moves in a circular motion around the axis of the mounting beam. Through the cooperation of the rotating rod with a gear mechanism, the rotating rod can rotate around its own axis, driving the photovoltaic panel to rotate relative to the mounting beam.

[0034] By setting up an installation sleeve with first and second threads in opposite directions, the installation sleeve is threadedly connected to the installation beam and secured with a fixing nut. The opposite threads prevent the installation sleeve from falling off and also effectively prevent loosening of the installation sleeve due to long-term use, thus enhancing the safety and reliability of the system.

[0035] The following description, in conjunction with the accompanying drawings, illustrates an angle-adjustable photovoltaic mounting bracket and its usage method according to the present invention.

[0036] See Figure 1 This shows a schematic diagram of the overall structure of the angle-adjustable photovoltaic mounting bracket of the present invention. (See also...)

Figure 1 , Figure 5 and Figure 7 This invention describes an angle-adjustable photovoltaic mounting bracket and its usage method.

[0037] like Figure 1 , Figure 5 and Figure 7 As shown, an angle-adjustable photovoltaic mounting bracket of the present invention includes: a plurality of first support rods 1 vertically fixed on the ground; a mounting beam 2 for mounting photovoltaic panels 5, rotatably disposed on the upper end of the first support rods 1 around its own axis, so that the photovoltaic panels 5 rotate synchronously with the mounting beam 2, thereby adjusting the orientation of the photovoltaic panels 5; a drive mechanism 16 disposed on the ground and connected to the mounting beam 2 for driving the mounting beam 2 to rotate; and a rotating rod 11 rotatably disposed inside the mounting beam 2 around its own axis, the rotating rod 11 also being able to... The photovoltaic panel 5 is rotatably mounted on the mounting beam 2 and rotates in a circular motion around the axis of the mounting beam 2, with the direction of rotation perpendicular to the surface of the photovoltaic panel 5. The rotating rod 11 is connected to the photovoltaic panel 5 so that the rotating rod 11 drives the photovoltaic panel 5 to rotate relative to the mounting beam 2 by rotating around its own axis. A gear mechanism 13 is provided on the ground on one side of the mounting beam 2 and is connected to the rotating rod 11 to allow the rotating rod 11 to rotate around its own axis while the mounting beam 2 rotates.

[0038] like Figure 11 As shown, specifically, several third support rods 12 are spaced apart inside the mounting beam 2. Bearings are fixed to the upper ends of both the first support rod 1 and the third support rod 12. The mounting beam 2 passes through the bearings at the upper ends of the first support rod 1 to achieve rotation. A rotating rod 11 passes through the bearings at the upper ends of the third support rod 12. Gear mechanisms 13 are provided at both ends of the mounting beam 2, and both ends of the rotating rod 11 extend from inside the mounting beam 2 and connect to the corresponding gear mechanisms 13.

[0039] In one specific embodiment, the gear mechanism 13 includes: a second support rod 132, vertically fixed to the ground; an internal gear ring 131 fixed to the upper end of the second support rod 132, the internal gear ring 131 being coaxially arranged with the crossbeam 2; a driven gear 133 fixed to one end of the rotating rod 11 and meshing with the internal gear ring 131, the size of the driven gear 133 being smaller than the size of the internal gear ring 131; a plurality of third support rods 12 are provided inside the mounting beam 2; the rotating rod 11 is rotatable around its own axis and is provided on the third support rod 12; and the rotating rod 11 and the mounting beam 2 are not on the same axis, so that when the rotating rod 11 rotates around the axis of the mounting beam 2, the rotating rod 11 rotates around its own axis through the meshing of the driven gear 133 and the internal gear ring 131.

[0040] The mounting beam 2 is rotatably provided with several support components 6. The photovoltaic panel 5 is fixed on the support components 6, and a connecting component 10 is provided between the rotating rod 11 and the support components 6, which is used to drive the support components 6 to rotate, thereby driving the photovoltaic panel 5 to rotate.

[0041] In one specific embodiment, the mounting beam 2 has a plurality of threaded holes 3 spaced apart, and a mounting sleeve 7 is internally threaded into each threaded hole 3. The support assembly 6 is rotatably mounted on the mounting sleeve 7. The support assembly 6 includes a locking block 61 and a support plate 62. The support plate 62 is rotatably mounted on the mounting sleeve 7. The locking block 61 is U-shaped and fixed to the support plate 62. A mounting frame 4 is provided on the locking block 61, and the photovoltaic panel 5 is mounted on the mounting frame 4. A support bearing 9 is provided at the upper end of the mounting sleeve 7, and the locking block 61 is fixed to the support bearing 9, thereby realizing the rotatable connection between the support assembly 6 and the mounting sleeve 7.

[0042] In one specific embodiment, the outer surface of the mounting sleeve 7 is provided with a first thread 71 and a second thread 72. The first thread 71 is located below the second thread 72 and engages with the internal thread of the screw hole 3. A fixing nut 8 is fitted on the mounting sleeve 7 and engages with the second thread 72. The first thread 71 and the second thread 72 have opposite directions of rotation, thereby preventing the mounting sleeve 7 from falling out of the screw hole 3 when the fixing nut 8 is fastened to the mounting sleeve 7.

[0043] like Figures 8 to 10As shown, in one specific embodiment, the mounting sleeve 7 is a hollow cylindrical shape. The connecting assembly 10 includes: a slider 101 disposed inside the mounting sleeve 7, with a groove at the bottom of the slider 101; a transmission rod 103 rotatably disposed in the groove, with a worm gear 104 fixedly mounted on the transmission rod 103, and a worm 111 meshing with the worm gear 104 on the rotating rod 11; and a mounting rod 107, the upper end of which is fixedly connected to the support assembly 6. The slider 101 has a through hole for the lower end of the mounting rod 107 to extend into the groove, and a second bevel gear 106 is fixedly mounted on the lower end of the mounting rod 107. A first bevel gear 105 meshing with the second bevel gear 106 is provided on the transmission rod 103. The bottom of the support plate 62 is provided with a limiting groove 63, and the upper end of the mounting rod 107 is provided with a limiting block 108. The limiting block 108 is embedded in the limiting groove 63 to achieve a fixed connection between the mounting rod 107 and the support plate 62.

[0044] In one specific embodiment, the inner wall of the mounting sleeve 7 is provided with a plurality of sliding grooves 73, the outer surface of the slider 101 is provided with a protrusion 102, the protrusion 102 is slidably disposed in the sliding groove 73; the annular mounting plate 109 is fixed on the inner wall of the mounting sleeve 7 and is located above the slider 101, and a spring 110 is provided between the slider 101 and the mounting plate 109.

[0045] In one specific embodiment, a crossbeam 15 is further included below the mounting beam 2. The crossbeam 15 is perpendicular to the mounting beam 2 and a connecting rod 14 is provided between them. The upper end of the connecting rod 14 is fixedly connected to the mounting beam 2, and the lower end is hinged to the crossbeam 15. The crossbeam 15 is movable to drive the mounting beam 2 to rotate around its own central axis via the connecting rod 14. The drive mechanism 16 is connected to the crossbeam 15 to drive the crossbeam 15 to move. Figure 12 As shown, the drive mechanism 16 drives the crossbeam 15 to move to the left or right, thereby causing the connecting rod 14 to rotate the mounting beam 2 to adjust the orientation of the photovoltaic panel 5.

[0046] like Figure 14 As shown, in one specific embodiment, the drive mechanism 16 includes: a U-shaped frame 161 fixed to the ground, a rotating frame 162 hinged inside the U-shaped frame 161, a servo motor 162 fixed on the rotating frame 162; a mounting member 164 and a screw 168, the mounting member 164 being fixed to the servo motor 162, one end of the screw 168 being hinged to the crossbeam 15, and the other end passing through the mounting member 164, the mounting member 164 having two meshing gears, one gear being connected to the output shaft of the servo motor 162, and the other gear being sleeved on the screw 168 and threadedly connected to the screw 168.

[0047] Preferably, the gears are three in number: a first gear 165 fixed to the output shaft of the servo motor 163, a second gear 166 meshing with the first gear 165, and a third gear 167 meshing with the second gear 166. The third gear 167 is sleeved on the screw 168 and threadedly connected to the screw 168. The drive motor drives the first gear 165 to rotate, which in turn drives the third gear 167 to rotate via the second gear 166, thereby adjusting the position of the third gear 167 on the screw 168. The screw 168 pulls or pushes the crossbeam 15 to move, causing the crossbeam 15 to rotate via the connecting rod 14, thus driving the mounting beam 2 to rotate.

[0048] In one specific embodiment, there are multiple mounting beams 2, the first support rods 1 are distributed in multiple rows at intervals, and all of the multiple mounting beams 2 are connected to the drive mechanism 16.

[0049] Specifically, it also includes an intelligent tracking system connected to the servo motor 163. By monitoring the direction of sunlight, it controls the switching of the servo motor 163 and the rotation direction of its output shaft, thereby causing the photovoltaic panel 5 to rotate synchronously through transmission, so that the photovoltaic panel 5 can receive direct sunlight.

[0050] The present invention also provides a method for using an angle-adjustable photovoltaic mounting bracket, specifically including the following steps: providing the photovoltaic mounting bracket as described above and installing the photovoltaic mounting bracket at the designed position; activating the drive mechanism 16, causing the drive mechanism 16 to drive the mounting beam 2 to rotate according to the angle of the sun, thereby driving the photovoltaic panel 5 to rotate synchronously with the mounting beam 2, so as to adjust the orientation of the photovoltaic panel 5 so that the top surface of the photovoltaic panel 5 faces the sun. While the mounting beam 2 is rotating, the rotating rod 11 is rotated around its own axis through the gear mechanism 13, thereby causing the rotating rod 11 to drive the photovoltaic panel 5 to rotate relative to the mounting beam 2.

[0051] The following is a detailed description of the usage process and working principle of an angle-adjustable photovoltaic fixing bracket according to the present invention.

[0052] Install the photovoltaic mounting bracket at the designed location, and then install the photovoltaic panel 5 on the mounting frame 4.

[0053] The intelligent tracking system is activated. It tracks the angle of sunlight. When the angle changes, the system activates servo motor 163, causing its output axis to rotate in the corresponding direction. This drives the first gear 165 to rotate, which in turn drives the third gear 167 via the second gear 166. This adjusts the position of the third gear 167 on the screw 168, causing the screw 168 to move the crossbeam 15. The connecting rod 14 then causes the mounting beam 2 to rotate in the corresponding direction, causing the mounting beam 2 to rotate the photovoltaic panel 5 vertically. This adjusts the vertical angle of the photovoltaic panel 5, ensuring it faces the sunlight and fully absorbs solar energy.

[0054] During the rotation of the mounting beam 2, the rotating rod 11 and the driven gear 133 rotate around the central axis of the mounting beam 2. The driven gear 133 rotates by meshing with the internal gear ring 131, thereby causing the rotating rod 11 to rotate. The rotating rod 11 drives the transmission rod 103 to rotate through the worm gear 111 and the worm wheel 104. The transmission rod 103 drives the mounting rod 107 to rotate through the first bevel gear 105 and the second bevel gear 106, thereby causing the support assembly 6 to rotate, which in turn drives the photovoltaic panel 5 to rotate in the horizontal direction to adjust the angle of the photovoltaic panel 5 in the horizontal direction.

[0055] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
