Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic light-chasing bracket with an angle-adaptive function. Background Art

[0002] Photovoltaic brackets are an indispensable part of solar power generation systems. They are specially designed for installing, placing, carrying and fixing solar panels (i.e., photovoltaic modules). These metal structure brackets not only carry the power generation body of the photovoltaic power station, but also are arranged in a specific direction and angle to maximize the reception of solar radiation and improve power generation efficiency. The safety, installation convenience and stability of photovoltaic brackets are its core requirements, which have an important impact on the power generation efficiency, investment income and maintenance cost of photovoltaic power stations. For example, the announcement number (CN112688627B) discloses a photovoltaic bracket, including purlins for supporting photovoltaic modules, columns for vertically fixing on a horizontal mounting surface, a main beam axially mounted on the column, and a support member for mounting the purlin on the main beam. The present invention also includes a first driving mechanism, a movable component, a fixing member and a second driving mechanism. The movable component is positioned on the column and is provided with a first tooth pattern, and the fixing member is fixed on the main beam and is provided with a second tooth pattern. The first driving mechanism drives the movable component so that the first tooth pattern and the second tooth pattern have two states of separation and engagement in the axial direction of the main beam. When the first tooth pattern and the second tooth pattern are separated, the second driving mechanism drives the main beam to rotate to adjust the angle. The photovoltaic bracket of the present invention has the advantages of stable structure, convenient angle adjustment and low cost.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1-Figure 9As shown, the present embodiment provides a photovoltaic light-chasing bracket with angle self-adaptation function, including a circular mounting seat 1 and a U-shaped mounting frame 2, the U-shaped mounting frame 2 is fixed on the circular mounting seat 1, a side-swinging angle adjustment component 3 is installed on the top of the U-shaped mounting frame 2, a first supporting plate 4 and a second supporting plate 5 are installed on the side-swinging angle adjustment component 3, the photovoltaic panel is placed on the first supporting plate 4 and the second supporting plate 5, a transverse mounting strip 6 is fixedly installed on the side walls of the first supporting plate 4 and the second supporting plate 5, a limiting slot is provided on the transverse mounting strip 6, a clamping and positioning component 7 is installed in the limiting slot, the clamping and positioning component 7 is used to fix the photovoltaic panel, after the photovoltaic panel is placed on the supporting plate, the limiting slot and the adjustment mechanism in the clamping and positioning component 7 can be used to easily and accurately adjust the fixed position of the photovoltaic panel to ensure that it is stable and does not deviate during the tracking process. This design not only simplifies the installation process, but also greatly improves the safety and stability of the photovoltaic panel. The first supporting plate 4 and the second supporting plate 5 are fixedly installed with the first rotating drive block 8 and the second rotating drive block 9 at the bottom. The first rotating drive block 8 and the second rotating drive block 9 are fixedly installed with a connector 10 at one end. A driving opening ring 11 is fixedly installed at one end of the connector 10, and the driving opening ring 11 is fixedly connected to the U-shaped mounting frame 2 through a positioning pin assembly 12. An installation slot is opened on the inner wall of the first rotating drive block 8, and a transverse lifting drive assembly 13 is installed in the installation slot. One end of the transverse lifting drive assembly 13 is fixedly connected to the bottom of the first supporting plate 4 and the second supporting plate 5. The driven connecting strip 14 installed on the upper part corresponds vertically, and the circular mounting seat 1 of the bracket is firmly installed on the ground or roof and other suitable positions to ensure that the bracket is stable and does not shake. The lateral lifting drive component 13 is built into the first rotating drive strip 8. According to the movement trajectory of the sun on that day, the lateral movement of the lateral lifting drive component 13 in the installation slot is controlled. With the driven connecting strip 14, under the action of the side swing angle adjustment component 3, through precise mechanical transmission, the first support plate 4 and the second support plate 5 are synchronously raised and lowered, driving the first support plate 4 and the second support plate 5 to adjust the angle, so that the photovoltaic panel can automatically track the sun and maintain the best light receiving angle. This process does not require manual intervention and is fully automated, which greatly improves the adjustment efficiency and accuracy. Through the functions of angle adaptation and height adjustment, the power generation efficiency and stability of the photovoltaic system are effectively improved, and the energy loss caused by poor light angle is reduced. At the same time, the convenient installation and maintenance design also reduces the operating cost, injecting new vitality into the development of the photovoltaic power generation field.

[0027] The side-swinging angle adjustment assembly 3 includes an angle adjustment seat 301, which is fixed on the top of the U-shaped mounting frame 2. An angle adjustment block 302 is rotatably mounted on the angle adjustment seat 301. Connecting sleeves 303 are fixedly mounted on both ends of the top of the angle adjustment block 302. A lifting connecting rod 304 is slidably inserted in the connecting sleeve 303. One end of the lifting connecting rod 304 is elastically connected to the angle adjustment block 302 through a connecting spring 305. A swing seat 306 is fixedly mounted on the other end of the lifting connecting rod 304. A swing connecting block 307 is rotatably mounted on the swing seat 306. The first supporting plate 4 and the second supporting plate 5 are respectively fixed on the swing connecting blocks 307 on both sides. By controlling the driving The open ring 11 is moved, and the angle adjustment block 302 slowly rotates in the horizontal direction to achieve angle adjustment of the photovoltaic panel. Under the action of the positioning pin assembly 12, the stability of the photovoltaic panel during use is improved and the photovoltaic panel is convenient to adjust. It is more flexible to use and suitable for chasing light in different seasons, which improves the power generation efficiency of the photovoltaic panel. The transverse lifting drive assembly 13 is controlled to make the first supporting plate 4 and the second supporting plate 5 rise and fall synchronously, driving the photovoltaic panel to achieve precise side swing adjustment, which not only improves the accuracy of the photovoltaic panel in tracking the sun, but also ensures that under different lighting conditions throughout the day, the photovoltaic panel can receive sunlight at the optimal angle, thereby maximizing the power generation efficiency.

[0028] The clamping and positioning assembly 7 includes a driving motor 701 and a bidirectional driving screw 702. The driving motor 701 is fixed to the inner wall of one end of the limiting slide groove. The bidirectional driving screw 702 is rotatably installed on the inner wall of the other end of the limiting slide groove through a first rotating joint 703. One end of the bidirectional driving screw 702 is fixedly connected to the output shaft of the driving motor 701. A threaded slider 704 is installed on the bidirectional driving screw 702. The threaded slider 704 is slidably engaged in the limiting slide groove. There are two threaded sliders 704. The blocks 704 are respectively located at the reverse thread ends of the bidirectional driving screw 702, and the first L-shaped clamping plate 705 and the second L-shaped clamping plate 706 are respectively fixedly installed on the two threaded sliders 704, and the first L-shaped clamping plate 705 and the second L-shaped clamping plate 706 are both slidably engaged in the smooth grooves provided on the first supporting plate 4 and the second supporting plate 5 through the limiting square block 707. When it is necessary to install or adjust the position of the photovoltaic panel, the driving motor 701 is started, and its power is directly transmitted to the bidirectional driving screw 702 through the output shaft. Due to the reverse thread design of the bidirectional driving screw 702, the two threaded sliders 704 installed thereon will move synchronously in opposite directions along the limiting slide groove under the action of the positive and reverse thread teeth respectively. As the threaded slider 704 moves, the first L-shaped clamping plate 705 and the second L-shaped clamping plate 706 move horizontally, and they slide in the smooth grooves on the supporting plates through the limiting square block 707, ensuring the smooth and precise movement. When the two clamping plates are close to the edge of the photovoltaic panel, the clamping force can be precisely controlled by fine-tuning the rotation speed of the drive motor 701 to achieve a stable clamping of the photovoltaic panel. This clamping and positioning method not only simplifies the installation steps and improves the installation efficiency, but also provides reliable support and fixation in the process of the photovoltaic panel tracking the sun, preventing it from being offset due to factors such as wind and vibration, thereby ensuring the safe operation of the photovoltaic panel and maximizing the power generation efficiency. At the same time, the easy maintainability of the clamping assembly also reduces the later maintenance costs and improves the economy of the overall system.

[0029] The positioning pin assembly 12 includes an L-shaped mounting frame 1201, a positioning pin rod 1202 is slidably mounted on one end of the L-shaped mounting frame 1201, one end of the positioning pin rod 1202 is inserted into a positioning hole groove opened on the side wall of the driving opening ring 11, and the positioning hole groove is distributed in an arc shape, and a lifting head 1203 is fixedly mounted on the other end of the positioning pin rod 1202, and a positioning column 1204 is fixedly mounted on the inner wall of the L-shaped mounting frame 1201, and a vertical bar 1205 is slidably sleeved on the positioning column 1204, and the vertical bar 1205 is fixedly mounted on the inner wall of the L-shaped mounting frame 1201. 05 is fixedly connected to the positioning pin 1202 at one end, and the vertical bar 1205 is elastically connected to the L-shaped mounting frame 1201 through the tightening spring 1206. When the relative position between the first rotating driving bar 8 and the U-shaped mounting frame 2 needs to be fixed, the operator can gently lift the lifting head 1203. This action drives the positioning pin 1202 to slide along the L-shaped mounting frame 1201 through the vertical bar 1205 until the positioning pin 1202 is completely disengaged from the positioning hole groove of the driving opening ring 11. At this time, the first rotating driving bar 8 can rotate freely to adjust the direction of the photovoltaic panel. After the adjustment is completed, the lifting head 1203 is released. Under the elastic force of the tightening spring 1206, the positioning pin 1202 will automatically slide into the positioning hole groove and move along its arc trajectory to the optimal locking position. Due to the arc-shaped design of the positioning hole groove, even if the first rotating drive block 8 is subjected to external forces within a certain range, the positioning pin rod 1202 can maintain a stable plug-in state, effectively preventing accidental loosening. The use of this positioning pin assembly 12 is simple and quick, and can be quickly locked and unlocked without complex tools, greatly improving the adjustment efficiency and convenience of the photovoltaic tracking bracket. At the same time, its stable and reliable connection effect also provides strong support for the stable operation of the photovoltaic panel in the process of tracking the sun, ensuring the maximization of power generation efficiency.

[0030] The transverse lifting drive assembly 13 includes a servo motor 1301, a driving threaded rod 1302 and a triangular positioning block 1303. The servo motor 1301 is fixed to the inner wall of one end of the mounting slot. The driving threaded rod 1302 is rotatably mounted on the inner wall of the other end of the mounting slot through a second rotating joint 1304. One end of the driving threaded rod 1302 is fixedly connected to the output shaft of the servo motor 1301. The triangular positioning block 1303 is fixed to the first rotating driving strip 8 through a first serpentine connecting rod 1305. One end of the triangular positioning block 1303 is connected to the bottom of the driven connecting strip 14. The driving threaded rod 1302 is threadedly mounted with a connecting slider 1306, which is slidably engaged in the mounting slot. The connecting slider 1306 is fixedly mounted with a second serpentine connecting rod 1307, and one end of the second serpentine connecting rod 1307 is fixedly mounted with an extrusion and lifting slider 1308. The extrusion and lifting slider 1308 is slidably engaged with the triangular positioning block 1303. When the height and lateral angle of the photovoltaic panel need to be adjusted, the servo motor 1301 is started, and its power is directly transmitted to the driving threaded rod 1302 through the output shaft to drive it to rotate. As the driving threaded rod 1302 rotates, the connecting slider 1306 slides smoothly along the mounting slot under the action of the thread, and the second serpentine connecting rod 1307 on the connecting slider 1306 moves accordingly, driving the extrusion and lifting slider 1308 to slide along the inclined surface of the triangular positioning block 1303. Since the triangular positioning block 1303 is fixed to the first rotating driving block 8 through the first serpentine connecting rod 1305 and is tightly fitted with the bottom of the driven connecting strip 14, the movement of the extrusion lifting slider 1308 will be converted into a vertical lifting force on the driven connecting strip 14. As the extrusion lifting slider 1308 continues to slide, the first supporting plate 4 and the second supporting plate 5 slowly rise under the drive of the driven connecting strip 14. When the extrusion lifting slider 1308 moves to the center position of the triangular positioning block 1303, the height adjustment of the photovoltaic panel can be achieved, and when the extrusion lifting slider 1308 continues to move from the center position of the triangular positioning block 1303, the driven connecting strip 14 can be tilted to achieve the adjustment of the lateral angle of the photovoltaic panel. This design not only ensures the stability and accuracy of the height adjustment and the lateral angle adjustment, but also realizes the automatic adjustment of the height and lateral angle of the photovoltaic panel through the precise control of the servo motor 1301, which greatly improves the adjustment efficiency and accuracy. At the same time, the compact structure of the transverse lifting drive assembly 13 also saves space, making the entire photovoltaic tracking bracket more compact and efficient.
