Description

Technical Field

[0001] The present invention relates to the technical field of solar panel brackets, and particularly to a solar rotating bracket. Background Art

[0002] Solar power generation is the process of converting solar energy into electrical energy, mainly including two categories: photovoltaic power generation and solar thermal power generation. In photovoltaic power generation, solar panels (also known as photovoltaic panels) are required. In order to enable the solar panels to achieve optimal light irradiation reception, brackets are usually used to tilt the solar panels at a certain angle according to the current latitude (for example, in Nanjing, the tilt angle is maintained at 32 degrees). However, during the day, the sun rises in the east and sets in the west, and its angle is not fixed. Currently, most of the brackets have a fixed angle after installation, which will lead to low power generation efficiency of the solar panels. To solve the above problems, the present invention provides a solar rotating bracket. Summary of the Invention

[0006] Preferably, the tensioning assembly includes two sets of winding and unwinding mechanisms, and the two sets of winding and unwinding mechanisms are symmetrically distributed with respect to the axis of the fixed shaft. The winding and unwinding mechanism includes: Multiple lower fixed pulleys, and multiple said lower fixed pulleys are fixedly installed on a support rod fixedly connected to a bracket; Multiple upper fixed pulleys, and multiple said upper fixed pulleys are fixedly installed on the lower side of the mounting frame; An electric winch, and the electric winch is installed on the support rod; A tension sensor, and the tension sensor is installed on the lower side of the corresponding mounting frame; A steel wire rope, one end of the steel wire rope is fixedly connected to the electric winch, and the other end sequentially bypasses multiple lower fixed pulleys and multiple upper fixed pulleys at intervals and is fixedly connected to the tension sensor; Among them, the two electric winches in the two sets of winding and unwinding mechanisms start and stop synchronously, and the rotation directions are opposite.

[0007] Preferably, the upper fixed pulley is rotatably installed with a slider through a shaft body fixedly connected to both sides thereof, the slider is slidably installed in a chute provided on the side wall of the mounting seat, the mounting seat is fixedly connected to the mounting frame, and a first spring is connected between the upper end groove wall of the chute and the corresponding slider, and the first spring has an elastic force for pulling the slider upward.

[0008] Preferably, the locking mechanism is installed inside the mounting seat, the upper end of the locking mechanism penetrates through the corresponding mounting seat and the mounting frame and abuts against a locking rod slidably installed inside the mounting frame, and one end of the locking rod away from the corresponding locking mechanism penetrates through the mounting frame and abuts against a fixed shaft.

[0009] Preferably, the locking mechanism includes: An arc-shaped elastic plate, the arc-shaped elastic plate is installed inside the mounting seat through a second spring and is located above the corresponding upper fixed pulley, and the opening of the arc-shaped elastic plate faces downward; Two abutting rods, the two said abutting rods are respectively fixedly installed at both ends of the arc-shaped elastic plate and are slidably installed on the mounting seat; A top rod, the top rod is fixedly installed on the arch top of the arc-shaped elastic plate, and the upper end of the top rod penetrates through the corresponding mounting seat and the mounting frame and abuts against a locking rod slidably installed inside the mounting frame.

[0015] Through the setting of the arc-shaped elastic plate, the abutting rod and the ejector rod, the present invention realizes the emergency protection when the steel wire rope breaks. When the steel wire rope breaks, the upper fixed pulley moves upward and abuts against the abutting rod, driving the ejector rod to move upward, so that the ejector rod can abut against and lock the locking rod, and the locking rod abuts against the fixed shaft. At the same time, the ejector rod will receive a reaction force, generating a pressing force on the arc-shaped elastic plate, and then the abutting ends of the two abutting rods will have a force to move away from each other, enabling the abutting rod to fix the steel wire rope more stably. This can not only prevent the steel wire rope from being thrown out and colliding with the solar panels, causing damage, but also keep the angle between the mounting frame and the bracket fixed, avoiding damage to the solar panels due to collision.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides a solar rotating bracket, as Figures 1 to 10 shown.

[0030] Embodiment 1: A solar rotating bracket includes a bracket which is installed on the ground at a specified position (fixed at the specified position on the ground by piling, and the position is determined by measuring in advance according to the array distribution mode of the solar panels). The bracket includes a first support rod 2 and a plurality of second support rods 3. The height of the second support rod 3 is higher than that of the first support rod 2. A fixed shaft 4 is fixedly installed between the first support rod 2 and the adjacent second support rod 3, and a fixed shaft 4 is also fixedly installed between two adjacent second support rods 3. The plurality of fixed shafts 4 are parallel to each other. A mounting bracket 1 is rotatably sleeved on the fixed shaft 4. The mounting bracket 1 is used to mount the solar panels. An angle is formed between the mounting bracket 1 and the horizontal plane (this angle can be adjusted according to the latitude of the specific use location. For example, when located in Nanjing, the inclination angle is maintained at 32 degrees to improve the power generation efficiency).

[0031] Below the two ends of the mounting frame 1, there are tensioning components. The tensioning components are used to adjust the heights of the two ends of the mounting frame 1, and then make the mounting frame 1 rotate around the corresponding fixed shaft 4 to adjust the angle of the mounting frame 1. The mounting frame 1 can be rotated according to the angle of the sun during the day to ensure that the sunlight is perpendicular to the solar panels on the mounting frame 1, thereby ensuring the power generation efficiency.

[0032] The tensioning components include two sets of winding and unwinding mechanisms. The two sets of winding and unwinding mechanisms are symmetrically distributed on both sides of the axis of the fixed shaft 4. The winding and unwinding mechanism includes multiple lower fixed pulleys 5, multiple upper fixed pulleys 6, an electric winch 7, and a tension sensor 8. Among them, multiple lower fixed pulleys 5 and multiple upper fixed pulleys 6 are staggered. The lower fixed pulleys 5 are fixedly installed on the support rods, the support rods are fixedly connected to the brackets, and multiple upper fixed pulleys 6 are fixedly installed on the lower side of the mounting frame 1.

[0033] The electric winch 7 is installed on the corresponding support rod, the tension sensor 8 is installed on the corresponding mounting frame 1. The electric winch 7 houses a steel wire rope 9. One end of the steel wire rope 9 is fixedly connected to the mounting frame 1, and the other end is connected to the tension sensor 8 after passing around the lower fixed pulley 5 and the upper fixed pulley 6 in sequence.

[0034] When the tensioning components are started, the electric winches 7 in the two sets of winding and unwinding mechanisms rotate synchronously in opposite directions. By controlling the winding and unwinding of the two steel wire ropes 9, the height difference between the two ends of the mounting frame 1 is adjusted to achieve angle adjustment.

[0035] Embodiment 2: On the basis of Embodiment 1, in order to prevent the mounting frame 1 from deflecting and damaging the solar panels installed thereon when the steel wire rope 9 breaks, a locking mechanism is provided inside the mounting frame 1. The locking mechanism can abut against the fixed shaft 4 when the steel wire rope 9 breaks, so that the angle of the mounting frame 1 is fixed.

[0036] In order to stably trigger the locking mechanism when the steel wire rope 9 breaks, sliders 10 are rotatably arranged on both sides of the upper fixed pulley 6. The sliders 10 are rotatably connected to the shaft bodies fixedly arranged on the side surfaces of the upper fixed pulley 6. The sliders 10 are slidably installed in the chutes 12 provided on the side walls of the mounting seat 11. The mounting seat 11 is fixedly connected to the mounting frame 1. A first spring 13 is provided between the sliders 10 and the top wall of the chute 12. The first spring 13 has an elastic force that pulls the first spring 13 upward. When the steel wire rope 9 breaks, the upper fixed pulley 6 loses the pulling force, and the sliders 10 move upward under the pulling force of the first spring 13, thereby triggering the locking mechanism.

[0037] The locking mechanism is installed on the mounting seat 11. The upper end of the locking mechanism penetrates through the corresponding mounting seat 11 and the mounting frame 1 and abuts against the locking rod 15 slidably installed inside the mounting frame 1. One end of the locking rod 15 away from the corresponding locking mechanism penetrates through the mounting frame 1 and fits against the fixed shaft 4.

[0038] The locking mechanism includes: an arc-shaped elastic plate 18 with its opening facing downward. The crown of the arc-shaped elastic plate 18 is installed inside the mounting seat 11 through a second spring 19 and is located above the upper fixed pulley 6. Both ends of the arc-shaped elastic plate 18 are fixedly connected with abutting rods 20. The two abutting rods 20 are slidably installed on the mounting seat 11. The crown of the arc-shaped elastic plate 18 is fixedly connected with a top rod 21. The upper end of the top rod 21 penetrates through the corresponding mounting seat 11 and the mounting frame 1 and abuts against the locking rod 15 slidably installed inside the mounting frame 1. The lower ends of the two abutting rods 20 are both wedge-shaped and are folded toward the direction of approaching each other.

[0039] When the steel wire rope 9 breaks, the upper fixed pulley 6 loses the pulling force, and the slider 10 moves upward under the pulling force of the first spring 13, causing the upper fixed pulley 6 to drive the steel wire rope 9 thereon to move upward. At this time, the abutting rod 20 will abut against the steel wire rope 9. During the upward movement of the abutting rod 20, the top rod 21 will be driven to rise through the arc-shaped elastic plate 18. The top rod 21 pushes the locking rod 15, causing the locking rod 15 to abut against the fixed shaft 4, so that the angle of the mounting frame 1 can be fixed, avoiding the large-scale unrestricted rotation of the mounting frame 1 caused by the breakage of the steel wire rope 9, resulting in the collision damage of the solar power generation panel thereon.

[0040] When the top rod 21 pushes the locking rod 15, the arc-shaped elastic plate 18 receives a reaction force, causing the two abutting rods 20 to obliquely abut against the steel wire rope 9, so that the abutting rod 20 can better fix the steel wire rope 9, avoiding the steel wire rope 9 from being thrown out and colliding with the solar panel, resulting in the collision damage of the solar panel.

[0041] In order to better lock the angle of the fixed shaft 4 by the locking rod 15, the end of the locking rod 15 close to the fixed shaft 4 is set as a wedge shape, and a card slot adapted to the locking rod 15 is provided on the fixed shaft 4. When the locking rod 15 receives the abutting force of the top rod 21, the wedge-shaped end of the locking rod 15 will be inserted into the corresponding card slot, so that the angle of the fixed shaft 4 can be locked. A return spring 24 is installed between the locking rod 15 and the mounting frame 1, which can reset the locking rod 15 when the top rod 21 no longer abuts against the locking rod 15, that is, the wedge-shaped end of the locking rod 15 exits the card slot.

[0042] Embodiment 3: Mounting arms 22 are installed on the bracket, that is, on both sides of the first support rod 2 or on both sides of the second support rod 3. Touch switches 14 are provided at both ends of the mounting arms 22. The touch switches 14 are electrically connected to the tensioning assembly through a control module 23. The setting of the touch switches 14 can limit the maximum rotation angle of the mounting frame 1 (for example, limit the rotation angle of the mounting frame 1 to 270 degrees), avoiding the excessive rotation angle of the mounting frame 1 from affecting the work.

[0043] A wind speed sensor 17 is also installed on the support. The wind speed sensor 17 is electrically connected to the tensioning assembly through the control module 23. The wind speed sensor 17 can detect the wind speed in real time. When the wind speed exceeds the set threshold (this value can be modified according to the actual usage situation), the control module 23 can be used to control the tensioning assembly to stop moving, so as to avoid excessive wind speed, resulting in swinging with the wind during rotation and causing damage to the support and the mounting frame.

[0044] Light sensors 16 are installed at both ends of the mounting frame 1. The light sensors 16 can detect the difference in sunlight at both ends of the mounting frame 1. The light sensors 16 are electrically connected to the tensioning assembly through the control module 23. The control module 23 is installed on the support. The control module 23 can collect the difference between the two light sensors 16. The staff can control the tensioning assembly to rotate once every certain period of time through the program pre-entered into the control module 23, and rotate until the difference between the two light sensors 16 is zero, so as to ensure that the sunlight is perpendicular to the solar panel, and then ensure the power generation efficiency of the solar panel.

[0045] Two light sensors 16, one wind speed sensor 17 and one control module 23 form a set of electric control components, and a set of electric control components is installed every certain distance (for example, 5 kilometers).

[0046] The staff can remotely send a signal to the control module 23, so that when the sun rises every day, the mounting frame 1 can be controlled to drive the solar panel thereon to rotate to the angle facing east and directly face the sun.

[0047] An angle sensor 25 is also installed on the support. The probe of the angle sensor 25 is connected to the corresponding mounting frame 1. When adjusting the angle of the mounting frame 1, the angle sensor 25 can be used to determine whether the angle of the mounting frame 1 has rotated to the adjusted angle, so as to judge whether a fault occurs. When a fault occurs, it is convenient for the staff to repair in time.

[0048] The tension sensor 8, the light sensor 16, the wind speed sensor 17, the control module 23 and the angle sensor 25 are all prior arts and have been widely used. Moreover, their specific structures and working principles are not the technical features of the present invention, so the present invention will not be described in detail. For example, the tension sensor 8 can adopt the QLS-10 model, the light sensor 16 can adopt the ALS-PT19-315C model, the wind speed sensor 17 can adopt the VMS-FSJT model, the control module 23 can adopt the Internet of Things module, and the angle sensor 25 can adopt the GTS200 model.

[0049] The electric winch 7, the tension sensor 8, the light sensor 16, the wind speed sensor 17, the control module 23 and the angle sensor 25 are respectively electrically connected to an external power supply through cables.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
