Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.

[0039] The following is for reference. Figures 1-7 The description of the suspension support device 100 according to an embodiment of the present utility model should be noted as follows: Figure 1 , Figure 6 and Figure 7 As shown, the suspension support device 100 of this utility model is applicable to a photovoltaic tracking bracket 200. The photovoltaic tracking bracket 200 includes a main shaft 300 and a drive shaft 400. The main shaft 300 and the drive shaft 400 can be connected by the suspension support device 100, thereby suspending and supporting the drive shaft 400 to reduce the deflection deformation of the drive shaft 400. Specifically, as... Figure 1 As shown, the drive shaft 400 is located below the main shaft 300. The upper part of the suspension support device 100 can be connected to the main shaft 300, and the lower part can be connected to the drive shaft 400, thereby achieving relative fixation between the main shaft 300 and the drive shaft 400.

[0040] like Figures 1-5 As shown, the suspension support device 100 according to an embodiment of the present utility model includes: a suspension structure 1, a pin structure 2, and a transmission seat 3.

[0041] The suspension structure 1 is used to suspend the main spindle 300. In actual installation, the suspension structure 1 can be installed and connected to the main spindle 300, such as by passing the main spindle 300 through the suspension structure 1, or by other means such as snap-fit ​​or screw-fit.

[0042] The suspension structure 1 is provided with a movable groove 111, and the pin structure 2 is slidably inserted into the movable groove 111. At the same time, the transmission shaft 400 can be installed below the pin structure 2 through the transmission seat 3. That is, when the pin structure 2 slides in the movable groove 111, it can drive the transmission seat 3 and the transmission shaft 400 to slide together relative to the movable groove 111. Thus, when the transmission shaft 400 is suspended below the main shaft 300 by the suspension support device 100, the transmission shaft 400 can move relative to the main shaft 300 along the movable groove 111 to realize the position adjustment of the transmission shaft 400 relative to the main shaft 300. In this way, the suspension support device 100 can flexibly adapt to the suspension requirements of the transmission shaft 400 and the main shaft 300 in different relative positions, that is, realize the adaptive adjustment of their relative positions.

[0043] The transmission seat 3 is sleeved outside the pin structure 2, and the transmission seat 3 and the pin structure 2 are ball jointed. Specifically, as shown in the figure... Figure 5 As shown, the upper part of the transmission seat 3 is provided with a through hole adapted to the pin structure 2. The pin structure 2 extends into the through hole along its axial direction and is fixed relative to the transmission seat 3, and a ball joint is formed at the through connection. Thus, the transmission seat 3 can be adjusted in multiple directions and angles on the pin structure 2, which is beneficial to compensate for the installation errors generated during the installation of the suspension support device 100 and the displacement deviation caused by the thermal expansion and contraction of materials.

[0044] Therefore, when the drive shaft 400 is installed below the pin structure 2 via the drive seat 3, the drive shaft 400 and the drive seat 3 can rotate together relative to the pin structure 2 and the main shaft 300 above the pin structure 2, thereby achieving adjustment in different directions and angles. This allows the suspension support device 100 to adapt to the support requirements of the drive shaft 400 and the main shaft 300 at different relative angles, improving the adaptability of the suspension support device 100 and achieving effective support for the drive shaft 400.

[0045] Furthermore, the transmission seat 3 is used to pass through the transmission shaft 400, meaning the transmission shaft 400 can extend axially into the transmission seat 3 so that the weight of the transmission shaft 400 can be supported by the transmission seat 3, and then transmitted to the main shaft 300 through the pin structure 2 and the suspension structure 1. This achieves suspension support of the transmission shaft 400 by the main shaft 300, improving the structural stability and reliability of the transmission shaft 400. After passing through the transmission seat 3, the transmission shaft 400 can rotate relative to the transmission seat 3, meaning that even after being suspended below the main shaft 300, the transmission shaft 400 can still rotate flexibly to achieve its transmission function, which is beneficial for improving the efficiency and lifespan of photovoltaic power generation.

[0046] According to the suspension support device 100 of this utility model, the transmission shaft 400 can be suspended below the main shaft 300 to achieve stable support for the transmission shaft 400. The suspension support device 100 is adjustable in multiple directions and angles, so that it can flexibly adapt to different relative positions or angles of the transmission shaft 400 and the main shaft 300, thus increasing the scope of application. As a result, the main shaft 300 can provide support for the transmission shaft 400 through the suspension support device 100, reducing the deflection deformation of the transmission shaft 400, improving the structural stability and reliability of the photovoltaic system, improving transmission efficiency, and having a simple structure that is easy to operate, maintain and disassemble.

[0047] In some embodiments, the suspension structure 1 includes a suspension bracket 12 and a suspension plate 11. The suspension bracket 12 has a through-space for the main shaft 300 to pass through. That is, when the suspension structure 1 is installed and engaged with the main shaft 300, the main shaft 300 can pass through the through-space of the suspension bracket 12 so that the suspension bracket 12 supports the main shaft 300. Thus, the main shaft 300 and the suspension structure 1 are installed and engaged by passing through, which eliminates the need for additional connecting parts, reduces the number of connecting parts, lowers the installation cost, and simplifies the assembly process.

[0048] The suspension bracket 12 can be constructed as a rectangular frame to form a through space that matches the shape of the main shaft 300. That is, the through space can be constructed as a rectangular space, or when the main shaft 300 has other shapes, the suspension bracket 12 can also be constructed as a shape that matches it.

[0049] The suspension plate 11 is connected to the lower part of the suspension bracket 12. The suspension plate 11 and the suspension bracket 12 can be connected by bolts or by other means, such as through-pin installation, to achieve the installation and cooperation of the two.

[0050] The movable groove 111 is formed in the suspension plate 11, that is, the pin structure 2 can pass through the movable groove 111 of the suspension plate 11, so that the weight of the pin structure 2, the transmission seat 3 and the transmission shaft 400 can be supported on the suspension plate 11 through the inner wall of the movable groove 111, thereby supporting the transmission shaft 400. The structure is simple and easy to install.

[0051] In some embodiments, there are at least two suspension plates 11, which can be set to two, three, or more, and the specific number can be flexibly set according to actual needs. At least two suspension plates 11 can simultaneously cooperate with the pin structure 2, and at least two suspension plates 11 can simultaneously hang on the suspension bracket 12. That is, the suspension bracket 12 and the pin structure 2 can be suspended and connected through at least two suspension plates 11 to improve the stability of the structural connection.

[0052] Meanwhile, at least two suspension plates 11 are spaced apart along the length of the main shaft 300, and each of the at least two suspension plates 11 is provided with a movable groove 111. The pin structure 2 passes through the movable grooves 111 of the at least two suspension plates 11 in sequence. In this way, the pin structure 2 can pass through at least two suspension plates 11 simultaneously, so that the weight of the drive shaft 400 and the drive seat 3 can be distributed among at least two suspension plates 11 at the same time. As a result, there are at least two points of force between the pin structure 2 and the suspension structure 1, which makes the installation of the pin structure 2 more stable.

[0053] like Figure 1 As shown, there are two suspension plates 11, which are spaced apart and positioned below the main shaft 300. Each suspension plate 11 has a movable groove 111. The middle part of the pin structure 2 is connected to the transmission seat 3, and the two ends of the pin structure 2 pass through the movable grooves 111 of the two suspension plates 11, so that the gravity of the transmission shaft 400 can act between the two suspension plates 11, making the force bearing of the suspension structure 1 more stable.

[0054] In some embodiments, at least two movable slots 111 of the suspension plates 11 are distributed opposite each other in the length direction of the main shaft 300. That is, when the movable slots 111 of the two suspension plates 11 are engaged with the pin structure 2, the pin structure 2 can be distributed parallel to the main shaft 300. In this way, when the weight of the transmission shaft 400 and the transmission seat 3 is transmitted to the main shaft 300 through the pin structure 2 and the suspension structure 1, the pin structure 2 will not generate excessive torsional force on the main shaft 300, thus ensuring the stability of the main shaft 300.

[0055] And / or, in some embodiments, at least two suspension plates 11 are distributed in parallel and spaced apart, such as Figure 1As shown, there are two suspension plates 11, both of which are flat. The two suspension plates 11 are facing each other and spaced apart along the length of the main shaft 300. The bottom of the suspension structure 1 is located between the two suspension plates 11. At the same time, the pin structure 2 is also located between the two suspension plates 11. Thus, the weight carried on the pin structure 2 can be evenly transferred to the suspension structure 1 through the two suspension plates 11, achieving balanced weight transfer and avoiding large-scale swaying or swinging when the transmission shaft 400 is suspended and supported by the suspension support device 100, thereby improving structural stability.

[0056] In some embodiments, the pin structure 2 includes a first pin 21 and a second pin 22, which are inserted into each other and fixed relative to each other by fasteners 23. That is, a portion of the outer diameter of one of the first pin 21 and the second pin 22 is smaller than a portion of the inner diameter of the other, so that the first pin 21 and the second pin 22 can achieve an insert-fitting connection. Figure 4 As shown, the end of the first pin 21 is inserted into the second pin 22 to achieve the insertion and engagement of the two. The fastener 23 can press the first pin 21 against the second pin 22 to achieve the fixed connection between the two.

[0057] It should be noted that the fastener 23 can be constructed as a bolt structure, which includes a screw part 5, a limiting head 6, and a nut 7. The screw part 5 can be sequentially inserted into the first pin 21 and the second pin 22. The limiting head 6 can press against the outside of the first pin 21 to press the first pin 21 against the second pin 22. The nut 7 is provided on the outside of the second pin 22 and is threadedly connected to the screw part 5. As the nut 7 is tightened, the first pin 21 is gradually pressed against the second pin 22, thereby achieving a fastening connection between the first pin 21 and the second pin 22.

[0058] One of the first pin 21 and the second pin 22 is ball-jointed with the transmission seat 3; wherein, the first pin 21 can form a ball-joint engagement with the transmission seat 3, or the second pin 22 can form a ball-joint engagement with the transmission seat 3, such as... Figure 5 As shown, the first pin 21 passes through the transmission seat 3 and is inserted into the second pin 22. The first pin 21 and the transmission seat 3 form a ball joint. Thus, the transmission seat 3 can swing in multiple directions and at multiple angles with the pin structure 2, which is beneficial for compensating for installation errors and displacement deviations caused by thermal expansion and contraction of materials.

[0059] There are two suspension plates 11, and the first pin 21 and the second pin 22 are respectively inserted into the movable grooves 111 of the two suspension plates 11. Specifically, as shown... Figure 1As shown, the first pin 21 passes through the movable groove 111 of one suspension plate 11 along the length direction of the main shaft 300, and the second pin 22 passes through the movable groove 111 of another suspension plate 11 along the length direction of the main shaft 300. The insertion direction of the first pin 21 is opposite to that of the second pin 22, so that the first pin 21 and the second pin 22 can be inserted and fitted along the length direction of the main shaft 300, realizing the through-connection of the pin structure 2 with the two suspension plates 11. Then, the first pin 21 and the second pin 22 are fixedly connected by fasteners 23. Thus, the pin structure 2 can slide along the movable groove 111, which is beneficial to compensate for the installation error of the suspension support device 100 and the displacement deviation caused by the thermal expansion and contraction of the material.

[0060] It should be noted that the first pin 21 and the second pin 22 can be made of wear-resistant plastic to reduce frictional loss between metal parts, reduce the risk of jamming, and thus improve transmission efficiency. Wear-resistant plastic can also significantly extend the service life of structural components and reduce maintenance costs. Alternatively, composite materials, alloys, or other materials can be used. In other words, the material of the pin structure 2 is not limited to a specific material.

[0061] In some embodiments, the suspension bracket 12 includes a crossbeam pad 121 and a lower suspension seat 122. The lower suspension seat 122 is connected to the lower part of the crossbeam pad 121 by at least two connecting rods 123 to jointly define the passage space. That is, the suspension bracket 12 can form a rectangular frame structure by connecting the crossbeam pad 121, the lower suspension seat 122 and at least two connecting rods 123. The crossbeam pad 121 and the lower suspension seat 122 are distributed opposite each other in the vertical direction, and the at least two connecting rods 123 are distributed opposite each other in the horizontal direction, thereby jointly defining the passage space.

[0062] The suspension plate 11 is connected to the lower suspension seat 122. Thus, when the main shaft 300 is inserted into the insertion space, the crossbeam pad 121 supports the main shaft 300 above it. The weight of the lower suspension seat 122, the pin structure 2 inserted on the suspension plate 11, the transmission seat 3, and the transmission shaft 400 can be suspended below the crossbeam pad 121 by the two connecting rods 123. This allows the transmission shaft 400 to be effectively suspended below the main shaft 300. The structure is simple and easy to install.

[0063] Among them, such as Figure 2 As shown, there can be two connecting rods 123. The crossbeam pad 121 and the lower suspension seat 122 are connected to each other through the two connecting rods 123 to form a through space. That is, there can be two connecting rods 123, or two sets of connecting rods 123, each set including at least one connecting rod 123, so that two or more connecting rods 123 can transmit force between the lower suspension seat 122 and the crossbeam pad 121 to ensure connection strength.

[0064] In some embodiments, the connecting rod 123 is detachably connected to the lower suspension seat 122 and the crossbeam pad 121, respectively. The connecting rod 123 may be configured as a bolt structure, comprising a threaded portion 5, a limiting head 6, and a nut 7. Both ends of the crossbeam pad 121 and the lower suspension seat 122 are respectively provided with through holes adapted to the threaded portion 5. Specifically, for example... Figure 2 As shown, the screw part 5 extends from the upper part of the crossbeam pad 121 downwards into the through hole of the crossbeam pad 121 and the through hole of the lower suspension seat 122. The nut 7 is threadedly connected to the screw part 5 from the lower part of the lower suspension seat 122. As the nut 7 is tightened, the lower suspension seat 122 gradually moves closer to the crossbeam pad 121 and presses against the main shaft 300. Thus, the suspension structure 1 and the main shaft 300 are relatively fixed, and the structure is simple and easy to maintain and install. Of course, the connection between the connecting rod 123 and the lower suspension seat 122 and the crossbeam pad 121 can also be other methods such as snap-fit ​​or plug-in, and is not limited to the specific form described above.

[0065] And / or, the suspension plate 11 is detachably connected to the lower suspension seat 122, wherein the suspension plate 11 can be fixed to the lower suspension seat 122 by bolts, such as Figure 2 , Figure 3 and Figure 6 As shown, the lower suspension seat 122 includes two side plates and a base plate. The cross-sectional shape at both ends is U-shaped, and each side plate is also approximately U-shaped. Through holes suitable for bolt insertion are formed at both ends of the two side plates. The screw portion 5 can be sequentially inserted into one suspension plate 11, the two side plates of the lower suspension seat 122, and the other suspension plate 11. The screw portion 5 is threadedly connected to the nut 7, thereby achieving a fixed connection between the suspension plate 11 and the lower suspension seat 122. Similarly, the connection between the suspension plate 11 and the lower suspension seat 122 can also be achieved through snap-fit ​​or plug-in connections, and is not limited to the specific form described above.

[0066] In some embodiments, the movable groove 111 is constructed as an arc-shaped groove, which extends in an arc shape along the circumference of the main shaft 300; that is, the movable groove 111 is constructed as an arc-shaped groove. Specifically, as shown... Figure 3 As shown, the suspension plate 11 has an arc-shaped groove with both ends pointing upwards and the middle curving downwards, and the shape, position, and curvature of the arc-shaped grooves of the two suspension plates 11 can be constructed to be the same. The circular shape of the arc-shaped groove can be located on the main shaft 300, i.e., within the through-space. Therefore, when the drive shaft 400 swings relative to the main shaft 300, the pin structure 2 can slide within the arc-shaped groove, allowing the drive shaft 400 to swing flexibly relative to the main shaft 300 to a certain extent when the suspension support device 100 suspends the drive shaft 400 at the bottom of the main shaft 300. This improves the flexibility of the structural design and avoids problems such as structural interference and rigid contact.

[0067] In some embodiments, the transmission seat 3 includes a sleeve portion 31 and a connecting plate portion 32. The connecting plate portion 32 is connected to the outer peripheral wall of the sleeve portion 31, and the connecting plate portion 32 is engaged with the pin structure 2 via a fisheye bearing 4. Specifically, as Figure 5 As shown, the connecting plate 32 has a through hole, into which a fisheye bearing 4 can be installed. The first pin 21 passes through the through hole and forms a hinged fit with the connecting plate 32 through the fisheye bearing 4. Simultaneously, the first pin 21 and the second pin 22 are inserted into each other and secured by fasteners 23. Therefore, the transmission seat 3 can rotate relative to the pin structure 2 to a certain extent. At the same time, as... Figure 7 As shown, the transmission seat 3 can be slightly offset relative to the pin structure 2 in the horizontal and vertical directions. Thus, the suspension support device 100 of this utility model can automatically compensate for installation errors and displacement deviations caused by thermal expansion and contraction of materials.

[0068] The sleeve portion 31 is adapted to be fitted onto the drive shaft 400. That is, when the suspension support device 100 and the drive shaft 400 are installed and fitted, the drive shaft 400 is simply passed through the sleeve portion 31 to complete the installation. The sleeve portion 31 has a through hole in the horizontal direction. The drive shaft 400 passes through the through hole to pass through the sleeve portion 31. Thus, the drive shaft 400 and the main shaft 300 can be suspended and installed by the suspension support device 100. The structure is simple and the installation is convenient.

[0069] This utility model also proposes a photovoltaic device.

[0070] The photovoltaic equipment according to the embodiments of the present invention includes a suspension support device 100 of any of the above embodiments. By providing the suspension support device 100, the main shaft 300 and the transmission shaft 400 can be movably connected, allowing the transmission shaft 400 to be suspended and supported on the main shaft 300. This effectively suspends and supports the transmission shaft 400, reducing the deflection of the transmission shaft 400 and improving the stability and reliability of the photovoltaic tracking bracket 200 system.

[0071] Meanwhile, the connection point between the drive shaft 400 and the drive seat 3 is located outside the movable groove 111 of the suspension plate 11, thereby improving the structural strength of the suspension support device 100. Furthermore, the pin structure 2 can be made of wear-resistant plastic, which reduces frictional loss between metal parts, thereby reducing the risk of jamming, improving transmission efficiency and service life, and reducing maintenance costs. The pin structure 2 and the drive seat 3 are connected by a ball joint via a fisheye bearing 4, which automatically compensates for system installation errors and displacement deviations caused by thermal expansion and contraction of materials.

[0072] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0073] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
