Description

Technical Field

[0001] This utility model relates to the field of photovoltaic brackets, and in particular to a photovoltaic tracking bracket and a solar panel assembly. Background Technology

[0002] In existing technologies, traditional photovoltaic tracking bracket designs generally employ a structure where the center of the main beam coincides with the center of rotation, meaning the rotation center of the drive mechanism and the main beam are located on the same horizontal plane. This design offers advantages such as structural symmetry and high stability, but it suffers from a large load torque, requiring the drive mechanism to have higher power to achieve rapid rotation, thus presenting certain limitations. Specifically, when dealing with extreme weather conditions such as strong winds, and with the drive mechanism's output power limited, the bracket's return-to-position protection speed is restricted, potentially leading to damage to the solar panels due to delayed deflection.

[0003] Therefore, a photovoltaic tracking bracket and solar panel assembly are needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic tracking bracket and a solar panel assembly, so that when the drive mechanism outputs a certain power, it can effectively increase the speed at which the photovoltaic bracket returns from a tilted state to a horizontal state, thereby improving the protection effect on the solar panel.

[0005] To solve the above-mentioned technical problems, this utility model provides a photovoltaic tracking bracket, including a fixed bracket, a bearing bracket, an eccentric reducer, a main beam body, and a bent pipe connector;

[0006] The eccentric reducer is disposed at the end of the fixed bracket;

[0007] One end of the main beam body is connected to the output end of the eccentric reducer, and the other end is rotatably connected to the bearing bracket through the bent pipe connector, for mounting the solar panel body;

[0008] The pipe bend connector includes a first connecting sleeve and a second connecting sleeve that are connected to each other and arranged in parallel.

[0009] The first connecting sleeve is rotatably mounted on the bearing bracket, and the second connecting sleeve is fixedly connected to the other end of the main beam body;

[0010] The vertical distance between the centerline of the first connecting sleeve and the centerline of the second connecting sleeve is the same as the eccentric radius of the eccentric reducer.

[0011] Furthermore, multiple bearing supports are provided;

[0012] The number of main beam bodies is matched with the number of bearing supports.

[0013] Furthermore, the eccentric reducer has two output ends, and the plurality of bearing supports are respectively located on both sides of the fixed support;

[0014] Two of the main beam bodies are respectively driven and installed between the bearing brackets and the fixed bracket located on both sides of the fixed bracket, and the remaining multiple main beam bodies are driven and installed between two adjacent bearing brackets.

[0015] Furthermore, the eccentric reducer has an output end, and the plurality of bearing supports are all located on one side of the fixed support;

[0016] One of the main beam bodies is disposed between the fixed bracket and the bearing bracket, and the remaining multiple main beam bodies are drivenly installed between two adjacent bearing brackets.

[0017] Furthermore, two second connecting sleeves are provided, and the two second connecting sleeves are symmetrically arranged on both sides of the bearing bracket for connecting with the main beam body located between two adjacent bearing brackets.

[0018] Furthermore, the first connecting sleeve and the second connecting sleeve are connected by an arc-shaped transition sleeve.

[0019] Furthermore, the first connecting sleeve, the second connecting sleeve, and the arc-shaped transition sleeve are integrally formed by stamping and bending.

[0020] Furthermore, the eccentric reducer is a geared motor with an eccentric central shaft sleeve.

[0021] On the other hand, this utility model also proposes a solar panel assembly, including the photovoltaic tracking bracket described in the above embodiments and multiple solar panel bodies;

[0022] Multiple solar panel bodies are fixedly installed on the main beam body;

[0023] When the main beam body rotates under the drive of the eccentric reducer, it simultaneously drives the multiple solar panel bodies to deflect.

[0024] Furthermore, a connecting channel steel is fixedly installed between two adjacent solar panel bodies;

[0025] The end of the connecting channel steel is provided with two symmetrically arranged locking blocks, and the side of the two locking blocks that are close to each other is set as an arc-shaped structure that is adapted to the outer wall of the main beam body.

[0026] The locking block is fastened to the main beam body by bolts.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] By setting the eccentric reducer as the driving mechanism and installing a bent pipe connector including a first connecting sleeve and a second connecting sleeve on the bearing bracket, and connecting both ends of the main beam body to the second connecting sleeve and the output end of the eccentric reducer respectively, and making the vertical distance between the center lines of the first connecting sleeve and the second connecting sleeve the same as the eccentric radius of the eccentric reducer, the solar panel body is installed using an eccentric configuration. This effectively reduces the horizontal distance between the center of gravity of the solar panel body and the rotation center when the solar panel body is tilted, thereby reducing the gravitational torque of the solar panel body and the driving load of the eccentric reducer. Therefore, when facing extreme weather such as strong winds, and when the output power of the eccentric reducer is a certain value, the protection speed of the bracket return is faster, thus improving the protection effect of the solar panel body.

[0037] The photovoltaic tracking bracket and solar panel assembly of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0038] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0039] Example 1

[0040] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a photovoltaic tracking bracket, including a fixed bracket 1, a bearing bracket 2, an eccentric reducer 3, a main beam body 4, and a bent pipe connector 5.

[0041] The eccentric reducer 3 is located at the end of the fixed bracket 1 and serves as a drive mechanism to drive the main beam body 4 to rotate, thereby achieving deflection control of the solar panel body 6.

[0042] One end of the main beam body 4 is connected to the output end of the eccentric reducer 3, and the other end is rotatably connected to the bearing bracket 2 through the bent pipe connector 5, for mounting the solar panel body 6.

[0043] The pipe bend connector 5 includes a first connecting sleeve 51 and a second connecting sleeve 52 that are connected to each other and arranged in parallel.

[0044] The first connecting sleeve 51 is rotatably mounted on the bearing bracket 2, and the second connecting sleeve 52 is fixedly connected to the other end of the main beam body 4.

[0045] It should be noted that the vertical distance between the axis of the first connecting sleeve 51 and the axis of the second connecting sleeve 52 is the same as the eccentric radius of the eccentric reducer 3. That is, through the cooperation of the bent pipe connector 5 and the eccentric reducer 3, an eccentric structure is formed to drive the main beam body 4 to rotate. This effectively reduces the horizontal distance between the center of gravity of the solar panel body 6 and the center of rotation when the solar panel body 6 is in an inclined state, thereby correspondingly reducing the gravitational torque of the solar panel body 6 and the driving load of the eccentric reducer 3. Therefore, when facing extreme weather such as strong winds, and when the output power of the eccentric reducer 3 is a certain value, the protection speed of the bracket return is faster, thereby improving the protection effect on the solar panel body 6.

[0046] The formula for the gravitational torque is M = G × L × sinθ, where M is the gravitational torque, G is the weight of the solar panel body 6, L is the horizontal distance from the center of rotation to the center of gravity of the solar panel, and θ is the angle between the solar panel body 6 and the ground (horizontal plane).

[0047] As shown in the above formula, L and M are inversely proportional. Therefore, by reducing the horizontal distance (L) from the center of gravity of the solar panel body 6 to the center of rotation, the gravitational torque of the solar panel body 6 can be reduced. Furthermore, due to the reduction in the gravitational torque of the solar panel body 6, the load driven by the eccentric reducer 3 can also be reduced accordingly. Thus, when the output power of the eccentric reducer 3 is constant, the solar panel body 6 can switch from a tilted state to a horizontal state more quickly. Consequently, in strong winds, the solar panel body 6 can return to its original position more quickly, thereby improving the protection effect of the solar panel body 6.

[0048] In this embodiment, multiple bearing brackets 2 are provided, and the number of main beam bodies 4 matches the number of bearing brackets 2, so that multiple sets of solar panel bodies 6 can be assembled at the same time.

[0049] like Figures 4 to 6 As shown, in a specific example, the shape of the eccentric reducer 3 and the layout of the bearing support 2 are further defined.

[0050] Specifically, the eccentric reducer 3 has two output ends, and multiple bearing supports 2 are located on both sides of the fixed support 1.

[0051] Two of the main beam bodies 4 are respectively driven and installed between the bearing brackets 2 and the fixed bracket 1 located on both sides of the fixed bracket 1, and the remaining multiple main beam bodies 4 are driven and installed between two adjacent bearing brackets 2.

[0052] In another example, the eccentric reducer 3 has an output end, and the plurality of bearing supports 2 are located on one side of the fixed support 1.

[0053] One of the main beam bodies 4 is disposed between the fixed bracket 1 and the bearing bracket 2, and the remaining multiple main beam bodies 4 are drivenly installed between two adjacent bearing brackets 2.

[0054] In summary, the relative positional relationship between the bearing bracket 2 and the fixed bracket 1 can be selectively adjusted by the number of output terminals of the eccentric reducer 3 to meet the control requirements for the deflection of multiple solar panel bodies 6.

[0055] In a further embodiment, the bend connector 5 is further defined to meet the transmission connection requirements of the main beam body 4 between two adjacent sets of bearing supports 2.

[0056] Specifically, there are two second connecting sleeves 52, and the two second connecting sleeves 52 are symmetrically arranged on both sides of the bearing bracket 2 for connecting with the main beam body 4 located between two adjacent bearing brackets 2.

[0057] It should be noted that the first connecting sleeve 51 and the second connecting sleeve 52 are connected by an arc-shaped transition sleeve 53.

[0058] In addition, the first connecting sleeve 51, the second connecting sleeve 52 and the arc-shaped transition sleeve 53 are integrally stamped and bent.

[0059] like Figure 3 As shown, in this embodiment, the eccentric reducer 3 is a geared motor with an eccentric central shaft sleeve, wherein the eccentric bearing sleeve is used to connect to the end of the main beam body 4.

[0060] Example 2

[0061] like Figures 4 to 7 As shown, this embodiment proposes a solar panel assembly based on embodiment one, including the photovoltaic tracking bracket and multiple solar panel bodies 6 described in embodiment one.

[0062] Multiple solar panel bodies 6 are fixedly installed on the main beam body 4. When the main beam body 4 is driven to rotate by the eccentric reducer 3, it synchronously drives the multiple solar panel bodies 6 to deflect.

[0063] By using an eccentric design to install the solar panel body 6, the horizontal distance between the center of gravity and the rotation center of the solar panel body 6 can be effectively reduced when the solar panel body 6 is tilted. This reduces the gravitational torque of the solar panel body 6 and the driving load of the eccentric reducer 3. Therefore, when facing extreme weather such as strong winds, and when the output power of the eccentric reducer 3 is a certain value, the protection speed of the bracket return is faster, thereby improving the protection effect of the solar panel body 6.

[0064] like Figure 7 As shown, a connecting channel steel 7 is also provided to facilitate the connection of two adjacent solar panel bodies 6.

[0065] Specifically, a connecting channel steel 7 is fixedly installed between two adjacent solar panel bodies 6.

[0066] The end of the connecting channel steel 7 is provided with two symmetrically arranged locking blocks 71, and the side of the two locking blocks 71 that is close to each other is set as an arc-shaped structure that is adapted to the outer wall of the main beam body 4.

[0067] In addition, the locking block 71 is fastened to the main beam body 4 by bolts. That is, by setting the connecting channel steel 7 and the locking block 71, the connection and positioning between the two solar panel bodies 6 and between the solar panel body 6 and the main beam body 4 are facilitated.

[0068] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
