Description

Technical Field

[0001] The invention relates to the field of photovoltaic component brackets, and in particular to an automatic adjustment photovoltaic component bracket and an adjustment method thereof. Background Art

[0002] As an important part of photovoltaic power stations, photovoltaic brackets carry photovoltaic modules and keep them at the best angle and direction to maximize the reception of sunlight. They are durable and adjustable to improve the power generation efficiency of photovoltaic systems and protect solar panels from external damage.

[0003] In areas with abundant solar energy resources, large-scale deployment of photovoltaic modules is a common practice to maximize the use of solar radiation for electricity production. At the same time, in order to facilitate maintenance and cleaning, these photovoltaic modules are often designed with adjustable angles to form a broad, continuous plane, which provides an unobstructed operating environment for photovoltaic cleaning robots, ensuring the cleanliness of the module surface, thereby maintaining the efficient operation and stable power generation capacity of the photovoltaic system.

[0004] However, with the change of seasons, the path and altitude angle of the sun will also change significantly. In winter, in order to better receive low-angle sunlight, the tilt angle of the photovoltaic module will be increased, and at this time, a shielding effect will appear between adjacent photovoltaic modules. Specifically, the upturned end of the photovoltaic module in the front will block part of the illuminated area of ​​the lowered end of the rear module, which directly leads to a reduction in the power generation of the shielded module. This phenomenon is more obvious at sunrise and sunset, and is more easily affected by the front module. Moreover, research shows that even a small range of shielding will significantly affect the current output of the photovoltaic module, because the series circuit has a "barrel effect", that is, the lowest current in the entire string of circuits determines the size of the overall current. Secondly, long-term shielding will also cause a hot spot effect, that is, the battery in the shielded part becomes an energy-consuming load, which not only reduces the overall power generation efficiency, but also causes the local temperature of the module to rise, affecting the performance of the packaging material. Based on this, the present invention purposely provides an automatic adjustment photovoltaic module bracket and an adjustment method thereof that can automatically adjust the angle and height of the photovoltaic module to avoid shielding between adjacent modules after the tilt angle of the module increases. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 4 As shown, the present invention is an automatic adjustment photovoltaic assembly support, comprising:

[0036] A first base 1, and a plurality of second bases 2 arranged in parallel at equal intervals are arranged on one side of the first base 1, a corresponding lifting plate 201 is slidably mounted on each second base 2, the lifting plate 201 is driven by a lifting assembly 6 to perform lifting movement, and the displacement distance of the lifting plate 201 farther from the first base 1 among two adjacent lifting plates 201 is twice the displacement distance of the lifting plate 201 farther from the first base 1, brackets 3 are fixedly mounted on the first base 1 and the lifting plates 201, the top of each bracket 3 is rotatably connected to the geometric center position of a frame 4, and an adjustment assembly 5 for driving the frame 4 to rotate is arranged thereon, the adjustment assembly 5 is connected to a controller, and a photovoltaic assembly is installed in each frame 4;

[0037] A displacement monitoring component is arranged on the first base 1, the displacement monitoring component is connected to the lifting component 6, and is connected to the controller;

[0038] a second displacement sensor 11, which is disposed on the lifting plate 201 close to the first base 1 and connected to the displacement monitoring assembly; and

[0039] When the inclination angle of the frame 4 is the smallest and the lifting plate 201 is close to the second base 2, the two adjacent frames 4 are aligned. When the controller drives the frame 4 to rotate through the adjustment component 5 so that the inclination angle of the frame 4 increases, the displacement monitoring component will obtain the displacement distance of the horizontal height of the end of the frame 4 before and after the rotation, and drive the lifting plate 201 to move upward through the lifting component 6 until the second displacement sensor 11 detects that the displacement distance of the lifting plate 201 close to the first base 1 is twice the displacement distance obtained by the displacement monitoring component, and stops the movement of the lifting plate 201.

[0040] In one case of the present embodiment, it should be noted that the controller described in the present invention includes a PLC control system, a season identification module, a signal receiving / transmitting module, a signal conversion module, etc., and the above-mentioned controller is the prior art, and the present invention does not improve it. Therefore, there is no need to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0041] In practical application, this embodiment is based on Figure 1 As shown in the example, two adjacent frames 4 are aligned, and the photovoltaic modules on all frames 4 form an inclined panel surface. At this time, the photovoltaic cleaning robot can perform cleaning operations along the inclined panel surface;

[0042] The controller will adjust the frame 4 to a suitable tilt angle through the adjustment component 5 according to the geographical location and seasonal conditions, so that the photovoltaic module can receive sunlight to the greatest extent. When the frame 4 rotates, the ends of two adjacent frames 4 will be staggered, so that the upturned end of the frame 4 at the front will block the sunken end of the frame 4 at the rear. At this time, it is necessary to drive each lifting plate 201 to rise and fall through the lifting component 6 until all the frames 4 can return to an inclined plane.

[0043] The specific operation is as follows: adjusting the inclination angle of the frame 4 will cause the frame 4 to rotate. After the frame 4 above the first base 1 rotates, the displacement monitoring component will obtain the displacement distance of the horizontal height of its end before and after the rotation. Since the rotating shaft of the frame 4 is located at its geometric center, the displacement distances at both ends are the same. Then the controller drives each lifting plate 201 to rise and fall through the lifting component 6, and the displacement distance of the lifting plate 201 adjacent to the first base 1 is twice the displacement distance obtained by the displacement monitoring component. At this time, the first frame 4 and the second frame 4 can be on the same inclined plane again, and the displacement distance of the lifting plate 201 farther from the first base 1 among the two adjacent lifting plates 201 is twice the displacement distance of the lifting plate 201 farther from the first base 1. This ensures that the lifting plate 201 farther from the first base 1 can be displaced a sufficient distance, so that all frames 4 can be on the same inclined plane, thereby avoiding obstruction.

[0044] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, the adjustment component 5 includes a support plate 501, a ring 502, an electric cylinder 503 and a linkage shaft 401, the support plate 501 is fixedly mounted on the bracket 3, the ring 502 is rotatably mounted on the support plate 501, the electric cylinder 503 is fixedly mounted in the ring 502, and it is connected to the controller, the linkage shaft 401 is fixedly mounted on the bottom of the frame 4, and the linkage shaft 401 is rotatably connected to the movable end of the electric cylinder 503.

[0045] In one case of this embodiment, it should be noted that the electric cylinder 503 described in the present invention is a prior art, and the present invention does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0046] In practical application, if Figure 4 As shown in the example, when the electric cylinder 503 extends, it pushes the linkage shaft 401 to move, so that the frame 4 rotates at the top of the bracket 3, thereby changing the inclination angle of the frame 4, and at the same time, the ring 502 also rotates, causing the electric cylinder 503 itself to deflect.

[0047] like Figure 1-Figure 2 As shown, as a preferred embodiment of the present invention, the displacement monitoring assembly includes an abutment plate 8, a spring 9 and a first displacement sensor 10, the abutment plate 8 is slidably installed on one end of the first base 1, and it is connected to the first base 1 through the spring 9, the top of the abutment plate 8 abuts against one end of the frame 4, the first displacement sensor 10 is fixedly installed on the top plate of the abutment plate 8, and it is connected to the second displacement sensor 11 and the controller.

[0048] In one case of this embodiment, it should be noted that the first displacement sensor 10 described in the present invention is a prior art, and the present invention does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0049] In practical application, this embodiment is based on Figure 1 Taking the direction shown as an example, when the adjusting component 5 drives the frame 4 to rotate so that the inclination angle of the frame 4 becomes larger, the sinking end of the frame 4 will compress the abutment plate 8, causing the spring 9 to contract. At this time, the first displacement sensor 10 will be close to the first base 1. According to the distance between the first displacement sensor 10 and the first base 1 before and after the rotation of the frame 4, the displacement distance of the end of the frame 4 can be obtained. Conversely, when the inclination angle of the frame 4 becomes smaller, the first displacement sensor 10 will move away from the first base 1, and the corresponding displacement distance can also be obtained.

[0050] like Figure 1-Figure 3As shown, as a preferred embodiment of the present invention, the lifting assembly 6 includes a threaded rod 202, a driving wheel 602, a guide rod 13 and a driving assembly. The four guide rods 13 are respectively fixedly installed at the four corners of the bottom of the lifting plate 201 and are slidably connected to the second base 2. One end of the threaded rod 202 passes through the second base 2 and is fixedly connected to the bottom of the lifting plate 201. The driving wheel 602 is rotatably installed at the bottom of the second base 2, is threadedly connected to the threaded rod 202, and is driven to rotate by the driving assembly. The number of rotations of the driving wheel 602 away from the first base 1 between two adjacent driving wheels 602 is twice the number of rotations of the driving wheel 602 close to the first base 1.

[0051] In actual application of this embodiment, due to the guiding effect of the guide rod 13, when the driving wheel 602 rotates, since it is threadedly connected with the threaded rod 202, the lifting plate 201 can be lifted and lowered on the second base 2, and the number of rotations of the driving wheel 602 away from the first base 1 between two adjacent driving wheels 602 is twice the number of rotations of the driving wheel 602 close to the first base 1, which can ensure that behind each lifting plate 201, all the frames 4 can be on the same inclined plane.

[0052] like Figure 2-Figure 3 As shown, as a preferred embodiment of the present invention, the driving assembly includes a linkage wheel 601, a synchronous belt 603 and a driving wheel 7, the driving wheel 7 is rotatably installed at the bottom of the first base 1, and is driven to rotate by the built-in output source of the first base 1, the built-in output source is connected to the controller, the driving wheel 7 is connected to the driving wheel 602 close to the first base 1 through the synchronous belt 603, the linkage wheel 601 is fixedly installed on the driving wheel 602, and its radius is twice the radius of the driving wheel 602, and the linkage wheels 601 at the bottom of two adjacent second bases 2 are connected to the driving wheel 602 through the synchronous belt 603.

[0053] In actual application of this embodiment, since the radius of the linkage wheel 601 is twice the radius of the driving wheel 602, and the two are connected by a synchronous belt 603, Figure 3 For example, the driving wheel 602 of the middle second base 2 is driven to rotate by the active wheel 7, then the interlocking wheel 601 under the middle second base 2 rotates the same number of times as the driving wheel 602, and the interlocking wheel 601 of the middle second base 2 will drive the driving wheel 602 of the left second base 2 to rotate, and the number of rotations is twice that of the driving wheel 602 corresponding to the middle second base 2, and so on, the number of rotations of the driving wheels 602 under two adjacent second bases 2 has the same multiple relationship, thereby ensuring that the driving wheel 602 can drive the threaded rod 202 to move a sufficient distance.

[0054] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, the bracket 3 is retractable, and the support plate 501 is fixedly mounted on the movable rod of the bracket 3.

[0055] In actual application of this embodiment, the retractable bracket 3 can retract the frame 4 to be close to the second base 2 when the device is idle, thereby reducing the occupied space and facilitating storage and transportation.

[0056] like Figure 4 As shown, as a preferred embodiment of the present invention, a groove 12 is provided at the bottom of the frame 4 , and the rotation connection between the movable end of the bracket 3 and the frame 4 is located in the groove 12 .

[0057] In practical application, the present embodiment is provided by setting the rotation connection between the bracket 3 and the frame 4 in the groove 12 at the bottom of the frame 4 instead of directly setting it on the side of the frame 4, thereby ensuring that Figure 1 In the state shown, a plurality of sets of first bases 1 and second bases 2 can be arranged side by side, and the frames 4 arranged side by side can also fit tightly.

[0058] See also Figure 1-Figure 4 As shown, the present invention is an automatic adjustment method for a photovoltaic component support, the method is applied to an automatic adjustment photovoltaic component support as described in the above embodiment, and the method comprises the following steps:

[0059] Step S1: The first base 1 and the plurality of second bases 2 are fixedly installed side by side at equal intervals on the ground;

[0060] Step S2: The controller adjusts the inclination angle of all frames 4 to the minimum through the adjustment component 5, and makes the lifting plate 201 close to the second base 2 through the lifting component 6. At this time, all frames 4 are aligned to form an inclined plane, and cleaning can be carried out in this state;

[0061] Step S3: The controller adjusts the inclination angle of the frame 4 through the adjustment component 5 according to the geographical location and seasonal conditions. At this time, the ends of two adjacent frames 4 are staggered, and the displacement monitoring component obtains the displacement distance of the horizontal height of the ends of the frame 4 before and after the rotation;

[0062] Step S4: driving the lifting plate 201 to move up and down by the lifting assembly 6 until the second displacement sensor 11 detects that the displacement distance of the lifting plate 201 close to the first base 1 is twice the displacement distance obtained by the displacement monitoring assembly, and stops the movement of the lifting plate 201. At this time, all the frames 4 are located on an inclined plane;

[0063] Step S5: As the seasons change, repeat steps S3-S4.

[0064] Working principle of the present invention: The above-mentioned embodiment of the present invention provides an automatic adjustment photovoltaic component support and an adjustment method thereof. Adjusting the inclination angle of the frame 4 will cause the frame 4 to rotate. After the frame 4 above the first base 1 rotates, the displacement monitoring component will obtain the displacement distance of the horizontal height of its end before and after the rotation. Since the rotating shaft of the frame 4 is located at its geometric center, the displacement distances at both ends are the same. Then the controller drives each lifting plate 201 to rise and fall through the lifting component 6, and the displacement distance of the lifting plate 201 adjacent to the first base 1 is twice the displacement distance obtained by the displacement monitoring component. At this time, the first frame 4 and the second frame 4 can be on the same inclined plane again, and the displacement distance of the lifting plate 201 farther from the first base 1 among the two adjacent lifting plates 201 is twice the displacement distance of the lifting plate 201 farther from the first base 1. This ensures that the lifting plate 201 farther from the first base 1 can be displaced a sufficient distance, so that all frames 4 can be on the same inclined plane, thereby avoiding obstruction.

[0065] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
