Description

An adaptive solar tracking photovoltaic bracket Technical Field

[0001] This invention relates to the field of solar energy utilization equipment technology, specifically to an adaptive solar tracking photovoltaic bracket. Background Technology

[0002] With the continuous development of solar power generation technology, adaptive solar tracking photovoltaic brackets are widely used in photovoltaic power plants, residential distributed photovoltaic systems and other scenarios because they can adjust the angle of photovoltaic panels in real time according to the direction of sunlight, thereby improving solar energy absorption efficiency.

[0003] Existing adaptive solar tracking photovoltaic (PV) brackets typically rely on a sliding rail and guide rail structure to adjust the angle of the PV panels. This involves a drive mechanism that moves the PV panels along the rails, changing their orientation. However, since PV brackets are often installed outdoors, debris such as stones, dust, and fallen leaves can easily accumulate in the gaps between the rails and guide rails. As this debris accumulates, the sliding resistance between the rails and guide rails increases, potentially causing them to jam. This prevents the PV panels from adjusting their angle properly, affecting solar energy absorption efficiency and potentially damaging the drive mechanism due to forced movement, reducing the lifespan of the PV bracket and increasing maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive solar tracking photovoltaic bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive solar tracking photovoltaic bracket, comprising an adjustment plate and a base. A drive motor is fixedly installed inside the base, and a drive shaft is fixedly installed at the output end of the drive motor. A rotating base plate is fixedly installed at the top of the drive shaft. A hinge seat one is fixedly installed at the top of the rotating base plate. The hinge seat one is rotatably connected to a hinge seat two via a pin. The hinge seat two is fixedly connected to the bottom left end of the adjustment plate. An electric telescopic rod is fixedly installed on the rotating base plate. A U-shaped frame is fixedly installed at the top of the electric telescopic rod. Connecting seats are fixedly installed on the inner walls of the front and rear sides of the U-shaped frame. A connecting shaft is rotatably connected to the inner side of the connecting seats via a bearing. A limiting roller is fixedly sleeved on the outer wall of the connecting shaft. The limiting roller is clamped at the front and rear edges of the adjustment plate, and the gap between the upper and lower sets of limiting rollers is greater than the thickness of the front and rear edges of the adjustment plate. A light sensing component is fixedly installed on the adjustment plate.

[0006] Furthermore, the front and rear edges of the adjusting plate are inclined skirts, and the left and right ends of the adjusting plate are provided with integrally formed anti-fall protrusions, and the thickness of the anti-fall protrusions is greater than the gap between the upper and lower sets of limiting rollers.

[0007] Furthermore, four optical sensing components are provided and distributed at four positions on the top of the adjustment plate. A solar photovoltaic panel is provided on the top of the adjustment plate, and the solar photovoltaic panel is staggered from the optical sensing components.

[0008] Furthermore, the optical sensing component includes a mounting compartment, which is fixedly mounted on an adjustment plate. A light sensor is installed inside the mounting compartment, and the top of the mounting compartment is covered with a transparent glass cover.

[0009] Furthermore, an elastic corrugated sleeve is fixedly installed on the top of the rotating base plate, the top of the elastic corrugated sleeve is fixedly connected to the bottom of the U-shaped frame, and the elastic corrugated sleeve covers the electric telescopic rod.

[0010] Furthermore, a reinforcing plate is provided at the connection between the electric telescopic rod and the rotating base plate, and the reinforcing plate is fixedly connected to the rotating base plate and the electric telescopic rod by screws.

[0011] Furthermore, the bottom of the base is provided with an integrally formed mounting ring, the mounting ring having a mounting hole, and an integrally formed reinforcing ring being provided at the mounting hole.

[0012] Furthermore, the outer wall of the rotating base plate is fitted with a shielding sleeve, which covers the gap between the rotating base plate and the base. The shielding sleeve is shaped like a trumpet, wider at the top and narrower at the bottom.

[0013] Furthermore, a storage battery is installed inside the base, and a wire connector is installed at the bottom of the adjustment plate. The wire connector is electrically connected to the solar photovoltaic panel through a wire harness, and the wire connector is electrically connected to the storage battery through a flexible cable. A sealing sleeve is installed at the point where the flexible cable passes through the rotating base plate, and the sealing sleeve is slidably fitted on the flexible cable.

[0014] Furthermore, the base is equipped with a controller and an information transceiver. The controller is connected to the information transceiver via a wiring harness. The information transceiver is connected to the optical sensing component, the drive motor, and the electric telescopic rod via a wireless communication component. The battery is electrically connected to the drive motor and the electric telescopic rod via a wiring harness.

[0015] Compared with the prior art, the beneficial effects of the present invention are: by adjusting the height of the U-shaped frame up and down by the electric telescopic rod, the height of the structure on the U-shaped frame is adjusted, so that the adjusting plate is pushed and rotated. Since the limiting roller is clamped at the edge of the adjusting plate, the adjusting plate can slide relative to the limiting roller during the adjustment process. This design can not only adjust the tilt angle of the adjusting plate, but also eliminates the need for slide rails, guide rails and guide grooves, thus avoiding the problem of being stuck by debris.

[0016] The drive motor drives the drive shaft to rotate, which in turn drives the rotating base plate to rotate. The rotation of the rotating base plate causes the electric telescopic rod and the hinge seat to move in a circular motion, which in turn drives the adjustment plate to move in a circular motion, adjusting the orientation of the adjustment plate. A light sensor component is set up to monitor the intensity of natural light in real time, thereby ensuring that the adjustment is made to the optimal tilt angle and orientation, and ensuring that the best light is received.

[0017] The front and rear edges of the adjustment plate are sloping skirts, and the left and right ends of the adjustment plate are provided with integrally formed anti-fall protrusions. The thickness of the anti-fall protrusions is greater than the gap between the upper and lower limit rollers. The sloping skirts allow debris that falls to the edge of the adjustment plate to roll off better, and the anti-fall protrusions prevent the adjustment plate from detaching from the upper and lower limit rollers.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: Please refer to Figures 1-10. The present invention provides a technical solution: an adaptive solar tracking photovoltaic bracket, including an adjustment plate 1 and a base 7. A drive motor 16 is fixedly installed inside the base 7. A drive shaft 17 is fixedly installed at the output end of the drive motor 16. A rotating base plate 6 is fixedly installed at the top of the drive shaft 17. A hinge seat 1 4 is fixedly installed at the top of the rotating base plate 6. A hinge seat 2 5 is rotatably connected to the hinge seat 1 4 through a pin. The hinge seat 2 5 is fixedly connected to the bottom left end of the adjustment plate 1.

[0022] An electric telescopic rod 8 is fixedly installed on the rotating base plate 6. A U-shaped frame 9 is fixedly installed at the top of the electric telescopic rod 8. Connecting seats 10 are fixedly installed on the inner walls of the front and rear sides of the U-shaped frame 9. A connecting shaft 11 is rotatably connected to the inner side of the connecting seat 10 via a bearing. A limiting roller 12 is fixedly sleeved on the outer wall of the connecting shaft 11. The limiting roller 12 is clamped at the front and rear edges of the adjusting plate 1, and the gap between the upper and lower sets of limiting rollers 12 is greater than the thickness of the front and rear edges of the adjusting plate 1. A photosensitive component 3 is fixedly installed on the adjusting plate 1. The height of the U-shaped frame 9 is adjusted up and down by the electric telescopic rod 8, thereby adjusting the height of the structure on the U-shaped frame 9, so that the adjusting plate 1 is pushed and rotated, and because of the limiting roller... 12 is clamped at the edge of the adjusting plate 1, so the adjusting plate 1 can slide relative to the limiting roller 12 during the adjustment process. This design can adjust the tilt angle of the adjusting plate 1 without the need for slide rails, guide rails, guide grooves, etc., and can avoid the problem of being stuck by debris. The drive motor 16 drives the drive shaft 17 to rotate, which in turn drives the rotating base plate 6 to rotate. The rotation of the rotating base plate 6 drives the electric telescopic rod 8 and the hinge seat 4 to make circular motion, which in turn drives the adjusting plate 1 to make circular motion, adjusting the orientation of the adjusting plate 1. The light sensor component 3 is set to monitor the natural light intensity in real time, thereby ensuring that the adjustment is to the optimal tilt angle and orientation, and ensuring that the best light is received.

[0023] The front and rear edges of the section plate 1 are inclined skirts 101. The left and right ends of the adjustment plate 1 are provided with integrally formed anti-fall protrusions 102, and the thickness of the anti-fall protrusions 102 is greater than the gap between the upper and lower sets of limiting rollers 12. The inclined skirts 101 allow debris that falls to the edge of the adjustment plate 1 to roll off better. The anti-fall protrusions 102 prevent the adjustment plate 1 from detaching from the upper and lower sets of limiting rollers 12.

[0024] Four light sensing components 3 are provided and distributed at four positions on the top of the adjustment plate 1. A solar photovoltaic panel 2 is provided on the top of the adjustment plate 1. The solar photovoltaic panel 2 is staggered from the light sensing components 3 to ensure the accuracy of natural light monitoring.

[0025] The optical sensing assembly 3 includes a mounting compartment 301, which is fixedly mounted on the adjustment plate 1. A light sensor 302 is installed inside the mounting compartment 301. A transparent glass cover 303 covers the top of the mounting compartment 301. The mounting compartment 301 is used to install the light sensor 302, and the transparent glass cover 303 is used to protect the light sensor 302 and prevent the light sensor 302 from being exposed.

[0026] An elastic corrugated sleeve 20 is fixedly installed on the top of the rotating base plate 6. The top of the elastic corrugated sleeve 20 is fixedly connected to the bottom of the U-shaped frame 9. The elastic corrugated sleeve 20 covers the electric telescopic rod 8, and the elastic corrugated sleeve 20 is set to protect the exposed parts of the electric telescopic rod 8.

[0027] A reinforcing plate 801 is provided at the connection between the electric telescopic rod 8 and the rotating base plate 6. The reinforcing plate 801 is fixedly connected to the rotating base plate 6 and the electric telescopic rod 8 by screws. The reinforcing plate 801 reinforces the connection between the electric telescopic rod 8 and the rotating base plate 6 and increases the stability of the connection.

[0028] The bottom of the base 7 is provided with an integrally formed mounting ring 701. The mounting ring 701 has a mounting hole and an integrally formed reinforcing ring 702 is provided at the mounting hole. The mounting ring 701 and the reinforcing ring 702 are provided to facilitate the fixing of the base 7 with anchor bolts or the like when fixing the base 7.

[0029] A shielding sleeve 22 is fitted on the outer wall of the rotating base plate 6. The shielding sleeve 22 covers the gap between the rotating base plate 6 and the base 7. The shielding sleeve 22 is shaped like a trumpet, which is larger at the top and smaller at the bottom. The shielding sleeve 22 is set to prevent rainwater from entering the base 7 from the gap between the rotating base plate 6 and the base 7. Because the shielding sleeve 22 is shaped like a trumpet, rainwater can drip off the shielding sleeve 22 better.

[0030] Working principle: During use, the intensity of natural light is monitored by the light sensor 302 inside the installation compartment 301. The light sensors 302 at four locations can monitor the natural light in a certain area, thereby better determining the direction of natural light. First, the drive motor 16 drives the drive shaft 17 to rotate, which in turn drives the rotating base plate 6 to rotate. The rotation of the rotating base plate 6 drives the electric telescopic rod 8 and the hinge seat 4 to make circular motion, which in turn drives the adjusting plate 1 to make circular motion, adjusting the orientation of the adjusting plate 1. Then, the electric telescopic rod 8 adjusts the height of the U-shaped frame 9 up and down, thereby adjusting the height of the structure on the U-shaped frame 9, so that the adjusting plate 1 is pushed and rotated, thereby adjusting the tilt angle of the adjusting plate 1, ensuring that the solar photovoltaic panel 2 on the adjusting plate 1 faces the natural light.

The limiting roller 12 is clamped at the front and rear edges of the adjusting plate 1, and the gap between the upper and lower sets of limiting rollers 12 is greater than the thickness of the front and rear edges of the adjusting plate 1. A photosensitive component 3 is fixedly installed on the adjusting plate 1. The height of the U-shaped frame 9 is adjusted up and down by the electric telescopic rod 8, thereby adjusting the height of the structure on the U-shaped frame 9, so that the adjusting plate 1 is pushed and rotated, and because of the limiting roller... 12 is clamped at the edge of the adjusting plate 1, so the adjusting plate 1 can slide relative to the limiting roller 12 during the adjustment process. This design can adjust the tilt angle of the adjusting plate 1 without the need for slide rails, guide rails, guide grooves, etc., and can avoid the problem of being stuck by debris. The drive motor 16 drives the drive shaft 17 to rotate, which in turn drives the rotating base plate 6 to rotate. The rotation of the rotating base plate 6 drives the electric telescopic rod 8 and the hinge seat 4 to make circular motion, which in turn drives the adjusting plate 1 to make circular motion, adjusting the orientation of the adjusting plate 1. The light sensor component 3 is set to monitor the natural light intensity in real time, thereby ensuring that the adjustment is to the optimal tilt angle and orientation, and ensuring that the best light is received.
