Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic bracket structure for a building roof. Background Art

[0002] The main function of the photovoltaic bracket is to stably support the solar panels. Currently, the roofs of buildings are common places for solar photovoltaic power generation and can be divided into sloping roofs and flat roofs.

[0003] For sloping roofs, when installing existing photovoltaic brackets, it is often necessary to first remove the roof tiles, then drill holes, and then fix a single bracket to the roof with bolts; this installation method not only destroys the original waterproof layer of the roof, greatly affecting the waterproof effect of the roof, but also when the bracket or photovoltaic equipment needs to be disassembled and repaired later, the bracket needs to be removed one by one. The operation process is cumbersome and consumes a lot of time and labor costs.

[0004] Moreover, most of the brackets on the market are fixed structures. Once the photovoltaic panels are installed on the brackets, the elevation angle cannot be adjusted as the sun moves. The position of the sun changes constantly throughout the day, and the photovoltaic panels with fixed angles cannot always receive sunlight at the best angle. This results in some solar energy not being fully utilized, resulting in energy waste.

DETAILED DESCRIPTION

[0040] The following combination Figures 1 to 15 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a building roof photovoltaic support structure, which is applied to the roof photovoltaic power generation system of the building, and is intended to improve the power generation efficiency and service life of the photovoltaic panel; by installing symmetrical connecting rails on the roof and setting stable connectors between the rails, the stability and connectivity of the overall structure are ensured; the adjustment components set in the connecting rails can adjust the position as needed to achieve precise installation and angle control of the photovoltaic panel. Through a specific swing device, the photovoltaic panel can swing, and the pitch angle can be adjusted in real time through a special rack and sliding mechanism to ensure that it always maintains the best angle with the sunlight, thereby maximizing the utilization efficiency of solar energy.

[0042] Example 1: Reference Figure 1 As shown, it includes a roof 1, slide rails 10, a support shaft 11, a sliding block 12, a mounting shaft 13 and a swing unit 2. The slide rails 10 are symmetrically installed on the roof 1, and a support shaft 11 is installed between the slide rails 10. The support shaft 11 is used to connect the two slide rails 10 to each other, thereby further increasing the connectivity between the slide rails 10.

[0043] The slide rail 10 is provided with several sliding blocks 12 connected thereto by bolts, and an installation shaft 13 is provided between the front and rear corresponding sliding blocks 12. According to usage requirements, the installation shaft 13 is installed between two corresponding sliding blocks 12, and then the position of the sliding block 12 on the slide rail 10 is moved. After the position is determined, the sliding block 12 is fixed to the slide rail 10 by bolt insertion.

[0044] A swing unit 2 for driving the photovoltaic panel to swing is arranged on the installation shaft 13 , and the installation shaft 13 is used to support the swing unit 2 .

[0045] Continue to refer to Figure 1 and Figure 2 As shown, the swing unit 2 drives the photovoltaic panel to swing; specifically, the swing unit 2 includes a semicircular ring 20, a swing shaft 21, a swing plate 22, an arc-shaped telescopic plate 220 and a mounting assembly 6, and several semicircular rings 20 are sleeved on the outside of the mounting shaft 13, that is, in actual use, the distance between the several semicircular rings 20 is set, and then the semicircular rings 20 can be fixed to the outside of the mounting shaft 13 by bolt insertion.

[0046] At the upper end of the semi-circular ring 20, a swing shaft 21 is rotatably installed. On the outside of the swing shaft 21, a swing plate 22 is provided. At the upper end of the swing plate 22, an arc-shaped telescopic plate 220 is provided. At the telescopic end of the arc-shaped telescopic plate 220, an installation component 6 for installing a photovoltaic panel is provided. When the swing shaft 21 is driven by an external force, it can drive the corresponding swing plate 22 to swing along its axis. The swing plate 22 drives the corresponding arc-shaped telescopic plate 220 to swing, and the swing plate 22 can indirectly drive the installation component 6 to swing synchronously.

[0047] Referring to Figure 3 As shown, specifically, the arc-shaped telescopic plate 220 is composed of an arc-shaped frame 221 and an arc-shaped rack 222. The arc-shaped frame 221 is located on the swing plate 22. The cross-section of the arc-shaped rack 222 is U-shaped. The arc-shaped rack 222 is slidably installed in the arc-shaped frame 221. The installation component 6 is located at the end of the arc-shaped rack 222. The swing plate 22 can drive the corresponding arc-shaped frame 221 to swing, and the arc-shaped frame 221 can drive the installation component 6 at its upper end to swing through the arc-shaped rack 222. When the arc-shaped rack 222 is driven by an external force, it can slide inside the corresponding arc-shaped frame 221 under the limit of the arc-shaped frame 221, thereby synchronously driving the installation component 6 above it to move synchronously, so as to indirectly drive the photovoltaic panel to adjust the pitch angle.

[0048] In most areas, usually, the photovoltaic panels are mostly placed facing south to obtain the best lighting conditions for efficient power generation. However, due to differences in the orientations of some houses, there is a certain deviation between the slope of the roof 1 and the due south direction. To ensure that the photovoltaic panels can face due south, during the implementation of this device, the swing shaft 21 can be driven to rotate by an external force to adjust the initial angle of the installation component 6 so that it precisely corresponds to the due south direction, thereby realizing precise adjustment of the angle of the photovoltaic panel, meeting the requirement that the photovoltaic panel faces due south, and ensuring that it is in the best power generation angle.

[0049] In practical applications, considering the change in the sun's trajectory within a day, during the process of moving from the south to the west, the direct sunlight angle changes continuously. To keep the photovoltaic panel always at the best angle with the sun's rays and achieve the most efficient power generation performance, the arc-shaped rack 222 is driven to move by an external force, thereby driving the pitch angle of the photovoltaic panel to be adjusted so that it can track the change in the sun's position in real time and make the most of solar energy for power generation.

[0050] Referring to Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, a driving unit 3 for driving the arc-shaped rack 222 to move is arranged in the arc-shaped frame 221; specifically, the driving unit 3 includes a driving ring gear 30, a driving shaft 31, a driving groove 32 and a driving key 33. The circular groove is provided on the inner wall of the arc-shaped frame 221 and is connected with the interior thereof. The driving ring gear 30 is rotatably arranged in the circular groove, and the driving ring gear 30 is meshed with the corresponding arc-shaped rack 222. The driving ring gear 30 can rotate in the circular groove when driven by an external force. During the rotation process, the driving ring gear 30 can drive the corresponding arc-shaped rack 222 to move up and down in the arc-shaped frame 221.

[0051] A driving shaft 31 is slidably provided on the arc frame 221 and passes through both sides thereof. The inner wall of the driving gear ring 30 is provided with several driving grooves 32 distributed along its axis. A driving key 33 meshing with the driving groove 32 is provided on the outer side of the driving shaft 31. That is, the driving shaft 31 can move in the front-rear direction under the limit guide of the arc frame 221 under the push of external force, and the driving shaft 31 can also rotate on the arc frame 221 under the drive of external force. When the driving shaft 31 rotates, it can synchronously drive the driving key 33 on its outer side to rotate. At this time, the driving shaft 31 can drive the driving gear ring 30 to rotate through the cooperation of the driving key 33 and the corresponding driving groove 32, so that the driving gear ring 30 can drive the arc rack 222 to move.

[0052] When the drive shaft 31 moves backward due to external force, the drive shaft 31 can synchronously drive the drive key 33 on its outer side to disengage from the corresponding drive groove 32. That is, when the drive shaft 31 rotates, it will not continue to drive the drive gear ring 30 to rotate. When the drive shaft 31 is pulled by external force again, the drive shaft 31 drives the drive key 33 on its outer side to engage with the drive groove 32 again. At this time, the drive shaft 31 can continue to drive the drive gear ring 30 to rotate.

[0053] Continue to refer to Figure 6 and Figure 7 As shown, a vibration component 4 for driving the photovoltaic panel to vibrate is also provided in the arc frame 221; specifically, the vibration component 4 includes an annular cavity 40, a vibration cam 41, a limiting groove 42, a limiting gear ring 43 and an annular plate 44, the annular cavity 40 is opened on the inner wall of the driving gear ring 30, and a vibration cam 41 located in the annular cavity 40 is provided on the outer side of the driving shaft 31.

[0054] In actual operation, the rotation of the drive shaft 31 will drive the outer vibration cam 41 to rotate synchronously in the annular cavity 40. When the drive shaft 31 drives the corresponding drive key 33 to no longer engage with the relevant structure, the vibration cam 41 is still in the annular cavity 40; at this time, the drive shaft 31 can be driven to drive the vibration cam 41 to rotate quickly in the same direction without being constrained by the arc-shaped rack 222 and the drive gear ring 30. The vibration cam 41 will vibrate during the rotation process, and the vibration force is transmitted to the mounting assembly 6 through the drive shaft 31, the arc-shaped frame 221, and the arc-shaped rack 222 in turn, and finally indirectly transmitted to the photovoltaic panel.

[0055] In winter, if snow accumulates on the top of the photovoltaic panels, or if they are covered with debris such as fallen leaves, it will seriously affect the photovoltaic panels' efficiency in absorbing solar energy, resulting in a significant drop in power generation capacity; excessive snow accumulation for a long time may cause structural damage to the photovoltaic panels due to weight issues, shortening their service life; if fallen leaves and other debris are left for a long time, they may rot in a humid environment and corrode the surface of the photovoltaic panels.

[0056] Therefore, it is extremely important to clean up the debris on the photovoltaic panel in time. By indirectly adjusting the pitch angle of the photovoltaic panel through the arc-shaped rack 222, the top surface of the photovoltaic panel is tilted at a large angle, which can allow snow, fallen leaves and other debris to slide off the upper end of the photovoltaic panel, restore the light-receiving area of ​​the photovoltaic panel, improve the power generation efficiency, and prevent the debris from causing damage to the photovoltaic panel.

[0057] However, sometimes the fallen objects on the photovoltaic panel cannot slide off completely, for example, the snow adheres to the photovoltaic panel due to ice or other reasons. At this time, the driving shaft 31 is driven to rotate by external force, and the photovoltaic panel on the mounting assembly 6 is driven to vibrate synchronously with the help of the vibration cam 41; this vibration can further destroy the adhesion between the snow and the photovoltaic panel, causing the snow to slide off, ensuring the clean surface of the photovoltaic panel, maintaining good power generation performance, extending the service life of the photovoltaic panel, and ensuring the stable operation of the photovoltaic power generation system.

[0058] A sliding cavity corresponding to the drive shaft 31 is provided on one side of the arc frame 221, and a plurality of limit grooves 42 corresponding to the drive groove 32 are provided on the inner side walls of the sliding cavity and the drive gear ring 30, and a limit gear ring 43 slides in the sliding cavity, and the teeth on the outer side of the limit gear ring 43 are inserted in the limit groove 42 on the inner wall of the sliding cavity, and an annular groove is provided on the inner wall of the limit gear ring 43, and an annular plate 44 is sleeved on the outer side of the drive shaft 31, which is located in the corresponding annular groove and is rotatably connected to the annular groove.

[0059] That is, only when the arc-shaped rack 222 drives the corresponding mounting assembly 6 to reach the maximum pitch angle, in order to improve the cleaning effect of fallen objects on the photovoltaic panel, the driving shaft 31 is driven by external force to drive the corresponding driving key 33 to disengage from the driving slot 32, so that the driving shaft 31 can drive the vibration cam 41 to rotate quickly to generate a vibration force, thereby further improving the cleaning effect of debris on the photovoltaic panel through the vibration force.

[0060] However, when the driving shaft 31 drives the driving key 33 to disengage from the corresponding driving groove 32, that is, at this time, the driving ring gear 30 is no longer supported by the driving shaft 31, and the gravity of the mounting assembly 6 will cause the arc-shaped rack 222 to be pressed and moved into the arc frame 221 by the mounting assembly 6. That is, at this time, the pitch angle of the photovoltaic panel does not meet the standard. Therefore, when the driving shaft 31 moves, the ring plate 44 will drive the limit ring gear 43 to move synchronously, so that the outer side of the limit ring gear 43 The teeth will mesh with the limiting groove 42 on the inner diameter of the driving gear ring 30. At this time, the limiting gear ring 43 will mesh with the limiting teeth on the sliding cavity and the inner wall of the driving gear ring 30 at the same time, so that the limiting gear ring 43 can provide limiting support for the driving gear ring 30, so as to indirectly prevent the arc-shaped rack 222 from sliding into the arc-shaped frame 221, thereby fixing the pitch angle of the photovoltaic panel. The driving shaft 31 is rotationally connected to the limiting gear ring 43, that is, when the driving shaft 31 rotates, it will not drive the limiting gear ring 43 to rotate.

[0061] After the fallen objects on the photovoltaic panel are cleaned by vibration, the driving shaft 31 drives the driving key 33 to move into the driving groove 32 again. Synchronously, the annular plate 44 drives the limiting gear ring 43 to move into the sliding cavity through the annular groove. That is, the driving shaft 31 can continue to indirectly drive the pitch angle of the photovoltaic panel to be adjusted through the driving key 33.

[0062] Reference Figure 8 and Fig. 9 As shown, adjacent drive shafts 31 are interconnected, and a drive assembly 5 for driving the drive shaft 31 to rotate or slide is commonly provided on one side of the drive shaft 31; specifically, the drive assembly 5 includes a linkage plate 50 and a drive cylinder 51, the linkage plate 50 is commonly provided on the outer side of the drive shaft 31 on the same side, and the drive cylinder 51 is provided on the arc frame 221 on one side through a cylinder seat, the telescopic end of the drive cylinder 51 is connected to the linkage plate 50, and the drive shafts 31 on the same side are interconnected by belt transmission, the drive cylinder 51 can drive the linkage plate 50 to move synchronously in the front and rear directions, and the linkage plate 50 can drive the left and right drive shafts 31 to move synchronously.

[0063] The drive shaft 31 on one side can be connected to the main shaft of an external drive motor. The external drive motor drives the drive shaft 31 on one side to rotate, and the drive shaft 31 on one side can rotate synchronously through a belt drive. In this way, the rotation and forward and backward movement of the drive shaft 31 are realized.

[0064] Refer to Fig.10 As shown, it is the mounting component 6 for mounting the photovoltaic panel. Specifically, the mounting component 6 includes a cross plate 60, a rectangular frame 61, a mounting groove 62, and a buffer pad 63. The cross plate 60 is arranged at the upper end of the arc rack 222. A rectangular frame 61 is arranged on the outer edge of the cross plate 60. A mounting groove 62 is formed on the cross plate 60. The inner cross section of the rectangular frame 61 is U-shaped, and a buffer pad 63 is arranged on the inner side wall of the rectangular frame 61.

[0065] Place the photovoltaic panel in the rectangular frame 61, and then rotate and insert the bolt into the mounting groove 62. One end of the bolt is connected to the insertion port at the rear end of the photovoltaic panel, fixing the photovoltaic panel in the rectangular frame 61. After the photovoltaic panel is installed in the rectangular frame 61, its rear end will contact the buffer pad 63, so that when the photovoltaic panel is driven by the vibration of the vibration cam 41, the buffer pad 63 can buffer the vibration of the photovoltaic panel, avoiding damage caused by hard contact between the photovoltaic panel and the rectangular frame 61.

[0066] Embodiment 2: Refer to Fig.11 、 Fig.12 and Fig.13 As shown, on the basis of Embodiment 1, a pulling component 7 for driving the swing shaft 21 and the arc rack 222 to work is arranged on the outer side of the mounting shaft 13. Specifically, the pulling component 7 includes a rotating gear ring 70, a limiting frame 71, a pulling rack 72, a clamping groove 73, a clamping cavity 74, a clamping block 75, and a pushing spring 76. The rotating gear ring 70 is sleeved on the outer side of the swing shaft 21, that is, when the rotating gear ring 70 is driven by an external force, it can drive the corresponding swing shaft 21 to rotate, so as to realize the effect that the swing shaft 21 indirectly drives the mounting component 6 to adjust the angle.

[0067] Several limiting frames 71 evenly distributed between the swing plates 22 are arranged on the outer side of the mounting shaft 13. A pulling rack 72 is slidably arranged among the limiting frames 71 on one mounting shaft 13, and the pulling rack 72 meshes with the corresponding rotating gear ring 70. The limiting frames 71 can limit the corresponding pulling rack 72, and the pulling rack 72 can move in the front and back directions under the limiting and guiding of the limiting frames 71, and the pulling rack 72 can drive the corresponding rotating gear ring 70 to rotate during the movement.

[0068] A plurality of snap-fit ​​grooves 73 are provided at the upper end of the pulling rack 72, and a snap-fit ​​cavity 74 corresponding to any one of the snap-fit ​​grooves 73 is provided in the limit frame 71. A snap-fit ​​block 75 slides in the snap-fit ​​cavity 74, and one side end of the snap-fit ​​block 75 slides through the outer wall of the limit frame 71 and is inserted into the corresponding snap-fit ​​groove 73, and a push spring 76 is also provided between the inner wall of the snap-fit ​​groove 73 and the snap-fit ​​block 75.

[0070] Example 3: Reference Fig.14 and Fig.15 As shown, on the basis of the first and second embodiments, in order to fix the slide rail 10 on the roof 1 without causing large-area perforations on the roof 1, a fixing component 8 for fixing it to the outer eaves of the house is provided on one side of the slide rail 10; specifically, the fixing component 8 includes an L-shaped plate 80 and a fixing bolt 81, the L-shaped plate 80 is symmetrically arranged on one side of the slide rail 10, a fixing groove is opened in the middle of the L-shaped plate 80, a fixing bolt 81 is threadedly connected in the fixing groove, and one side of the fixing bolt 81 is inserted into the outer wall of the house, so that the slide rail 10 is indirectly fixed to the roof 1, eliminating the step of opening several fixing holes on the roof. In the subsequent disassembly process, it is only necessary to remove the fixing bolt 81 on the L-shaped plate 80 to remove the present mechanism together.

[0071] During work: Step 1: Install the slide rails 10 and the support shafts 11, install the slide rails 10 symmetrically on the roof 1, and ensure that the spacing between the slide rails 10 is appropriate to provide a stable support structure; then install the support shafts 11 between the slide rails 10, and firmly connect the support shafts 11 to the slide rails 10 with bolts.

[0072] Step 2: Install the sliding block 12 and the mounting shaft 13. Set the sliding block 12 in the slide rail 10, and tightly connect the sliding block 12 and the slide rail 10 with bolts to ensure that the sliding block 12 can slide freely in the slide rail 10 but will not get loose; install the mounting shaft 13 between two corresponding sliding blocks 12 according to usage requirements; after completing the positioning of the mounting shaft 13, move the position of the sliding block 12 on the slide rail 10, and after determining the optimal position, firmly fix the sliding block 12 on the slide rail 10 with bolts; ensure that the mounting shaft 13 can stably support the subsequent swing unit 2.

[0073] Step 3: Install the swing unit 2, sleeve several semicircular rings 20 on the outside of the installation shaft 13, adjust the distance between the semicircular rings 20, and fix them on the outside of the installation shaft 13 with bolts to ensure that the semicircular rings 20 are stable.

[0074] Step 4: Adjust the angle of the photovoltaic panel. Drive the swing shaft 21 to rotate through external force, adjust the initial angle of the mounting assembly 6 to make it accurately correspond to the south direction, and ensure that the photovoltaic panel is facing the optimal power generation direction; in daily use, according to the trajectory of the sun, drive the arc rack 222 to move through external force to adjust the pitch angle of the photovoltaic panel so that it always maintains the optimal angle with the sunlight, thereby achieving efficient power generation of the photovoltaic panel.

[0075] Step 5: Clean the fallen objects on the photovoltaic panel. The pitch angle of the photovoltaic panel is adjusted by the arc-shaped rack 222 so that the top surface is tilted at a large angle, so that snow, fallen leaves and other debris can slide off the upper side of the photovoltaic panel to achieve automatic cleaning. If the debris cannot slide off completely, for example, snow adheres to the photovoltaic panel due to ice, the drive shaft 31 is driven to rotate by external force, and the photovoltaic panel is driven to vibrate by means of the vibration cam 41, so as to further destroy the adhesion between the debris and the photovoltaic panel and cause the debris to slide off.

[0076] Step 6: Install the component 6 to fix the photovoltaic panel, place the photovoltaic panel in the rectangular frame 61, and fix it in the installation component 6 by bolts to ensure that the photovoltaic panel is firmly installed; after the photovoltaic panel is installed in the rectangular frame 61, its rear end will contact the buffer pad 63, so that when the photovoltaic panel is driven by the vibration of the vibration cam 41, the buffer pad 63 can buffer the photovoltaic panel to avoid damage caused by hard contact between the photovoltaic panel and the rectangular frame 61; at the same time, when the drive shaft 31 drives the drive key 33 to disengage from the drive groove 32, the limit gear ring 43 moves through the annular plate 44, meshes with the limit groove 42 on the inner diameter of the drive gear ring 30, and provides limit support for the drive gear ring 30 to fix the pitch angle of the photovoltaic panel.

[0077] Step 7: The drive shaft 31 is driven and linked, and the drive shaft 31 is driven to move in the front-to-back direction through the linkage plate 50 and the drive cylinder 51 to achieve precise adjustment of the angle of the photovoltaic panel; the drive shaft 31 on one side is connected to the main shaft of the external drive motor, and the drive shaft 31 on one side is driven to rotate by the external drive motor, and the drive shaft 31 on the other side is synchronously driven to rotate by belt transmission.

[0078] Step 8: Fix the slide rail 10 on the roof 1, install an L-shaped plate 80 on one side of the slide rail 10, a fixing groove is opened in the middle of the L-shaped plate 80, and a fixing bolt 81 is threadedly connected in the fixing groove; insert the fixing bolt 81 into the outer wall of the house to fix the slide rail 10 to ensure that the slide rail 10 is firmly installed on the roof 1; ensure the stability of the entire device to prevent displacement or damage under severe weather conditions.
