[0029] In order to solve the problems in the prior art, the present invention proposes an adjustable bracket. Figure 1-6 The embodiment 1 of the present invention is shown in FIG. Figure 7 The embodiment 2 of the present invention is shown in FIG.

[0030] The adjustable bracket includes a column 1, a main beam 2, a supporting component 3, a driving component 4 and a stabilizing component 5.

[0031] In Example 1, Figure 1 As shown, the lower end of the column 1 is fixed on the surface of the target object (such as the ground), and the upper end rotatably supports the main beam 2. The main beam 2 supports multiple photovoltaic modules 7 through structures such as purlins 6 fixed thereon.

[0032] See also Figure 2-3, the support component 3 is fixed on the column 1 to support the driving component 4 and the stabilizing component 5, which is located below the main beam 2 and is separated from the main beam 2 by a distance. Specifically, the support component 3 includes a first support plate 31, a second support plate 32 and a third support plate 33. The first support plate 31 is fixed to the column 1. In the embodiment, the first support plate 31 is "L" shaped, including two mutually perpendicular planes, one plane is fixed to the column 1 by welding or bolt connection, and the other plane is provided with a first mounting hole (311) for mounting the second support plate 32. In the embodiment, the first mounting hole 311 on the first support plate 31 is a waist-shaped hole. In this way, the alignment requirements of the first and second support plates are reduced when punching holes, and the manufacturing is more convenient. The waist-shaped hole is longer, which is convenient for the second support plate 32 to be properly adjusted along the length direction of the waist-shaped hole. Furthermore, the waist-shaped hole has a certain inclination angle. After the first support plate 31 is fixed on the column 1, the center line a (see Figure 4 ) passes through the rotation center of the main beam 2.

[0033] See also Figure 3 The second support plate 32 is configured as a rectangular plate, and the mounting holes thereon are second mounting holes 321, which are two circular holes, and the line connecting the centers of the two circular holes is basically colinear with the center line of the second support plate 32 (the center line parallel to the direction of the line connecting the centers of the two circular holes).

[0034] The third support plate 33 is a "U" shaped plate, see Figure 2 The bottom plate is fixed on the upper side of the second support plate 32. When viewed from one end of the main beam 2, Figure 3 , the third support plate 33 is aligned with the center line of the second support plate 32, such as Figure 3 as shown in .

[0035] See also Figure 3 Two follower mounting holes (i.e., third mounting holes) 331 are provided on both side walls of the third support plate 33, see Figure 6 The two ends of the follower 51 are rotatably supported on the two side plates of the third support plate 33, and the rotation axis of the follower 51 is parallel to the bottom plate of the third support plate 33. When viewed from one end of the main beam 2, see Figure 3 , 6 The perpendicular bisector of the line connecting the rotation centers of the two followers 51 on the same side plate coincides with the center line of the side plate, that is, viewed from one end of the main beam 2, the two followers 51 are symmetrically arranged on the third support plate 33.

[0036] In this way, viewed from one end of the main beam 2, the rotation centers of the two followers 51 are symmetrical about the center line a, thus ensuring that the distances between the two followers 51 and the outer periphery of the arc-shaped gear ring 42 are substantially equal.

[0037] The above is a preferred arrangement of the support component 3 in the present application. In this embodiment, the manufacturing is simple and the installation is convenient. After installation, the distances between the two followers 51 and the outer periphery of the arc gear ring 42 are substantially equal. In other embodiments, the shape of the second support plate 32 is not necessarily rectangular, and the connecting line of the two mounting holes (i.e., the second mounting holes) thereon is not necessarily collinear with the center line of the second support plate 32, and the two followers 51 are not necessarily symmetrically arranged on the third support plate 33. During installation, it is sufficient to ensure that, from one end of the main beam 2, the perpendicular bisectors of the rotation centers of the two followers 51 are collinear with the center line a in the length direction of the waist-shaped hole.

[0038] In addition, the waist-shaped hole on the first supporting plate 31 and the two round holes on the second supporting plate 32 are interchangeable.

[0039] In other embodiments, the waist-shaped hole provided on the first support plate 31 may also be replaced by a circular mounting hole and an arc-shaped mounting hole.

[0040] Furthermore, in other embodiments, the first support plate 31 and the second support plate 32 may also be integrated, and in this case, the positions of the two followers 51 can be ensured by controlling the inclination of the mounting surface of the bottom plate of the third support plate 33 (this mounting surface is a plane on the combination of the first mounting plate 31 and the second mounting plate 32).

[0041] See also Figure 5-6 The transmission component 4 includes a gear 41 and an arc-shaped gear ring 42. The gear 41 is fixedly connected to a support rod 43 that passes through the center of the gear 41 along its axial direction, and is rotatably supported on the third support plate 33 through the support rod 43. The support rod 43 is transmission-connected to the driving source, and the gear 41 is meshed with the arc-shaped gear ring 42. The inner ring of the arc-shaped gear ring 42 has teeth, and its two ends are respectively fixedly connected to the lower end of a connecting rod 44, and the upper ends of the connecting rod 44 are fixedly connected to the main beam 2.

[0042] During operation, the driving source can drive the gear 41 to rotate through the support rod 43, thereby driving the arc-shaped gear ring 42 to rotate, and further driving the main beam 2 to rotate.

[0043] The gear 41 is a double gear, and the two gears are of the same size. The arc gear ring 42 also has two rows of teeth, which mesh with the gear 41 for transmission. The double rows of teeth on the arc gear ring 42 are formed by rolling C-shaped steel, and then the rolled C-shaped steel is pressed into an arc shape to obtain the arc gear ring 42 of the present invention. This arc gear ring uses less material and has low cost.

[0044] In the present invention, the adjustable bracket further comprises a stabilizing component 5, wherein the stabilizing component 5 comprises two followers 51, see Figure 6 As described above, two followers 51 are rotatably mounted on the third support plate 33, the rotation axis of the followers 51 is parallel to the rotation axis of the gear 41, the arc gear ring 42 is located between the gear 41 and the followers 51, and the followers 51 can rotate under the drive of the arc gear ring 42, thereby making the movement of the arc gear ring 42 more stable. The followers 51 can be rollers or gears. When the followers 51 are rollers, the outer periphery of the rollers abuts against the outer periphery of the arc gear ring 42, and follow the movement through friction. Further, in order to increase the friction between the two, the outer ring of the arc gear ring 42 and / or the outer periphery of the followers 51 can be covered with a material that can increase the friction between the two; when the followers 51 are gears, the outer periphery of the arc gear ring 42 is also provided with matching teeth or grooves for meshing, and when the arc gear ring 42 rotates, the followers 51 (gears) are driven to rotate.

[0045] Furthermore, the stabilizing component 5 also includes a brake member 52, which is a screw. The end of the follower 51 is provided with a plurality of through holes at a plurality of angles perpendicular to the rotation axis of the follower 51. When the arc gear ring 42 rotates, the follower 51 rotates. When the arc gear ring 42 stops rotating, the follower 51 stops rotating. Some of the plurality of through holes at its end are nearly horizontal. The follower 51 is rotated for fine adjustment, and then the brake member 52 is passed through the through holes at the ends of the two followers 51 in turn and then locked with a nut. At this time, the follower 51 will no longer be able to rotate, and it will also limit the rotation of the arc gear ring 42, thereby achieving braking.

[0046] Furthermore, the mounting hole (i.e., the third mounting hole 331) of the follower 51 on the third support plate 33 is set as a waist-shaped hole, and a support member (not shown in the figure) is set on the bottom plate of the third support plate 33, and the support member is used to adjust the tightness of the fit between the follower 51 and the arc-shaped gear ring 42. The support member can be a bolt with an arc-shaped end, which is screwed into the bottom plate of the third support plate 33 from bottom to top and supported under the follower 51. When the follower 51 adjusts its position along the waist-shaped hole, after the position adjustment is completed, the bolt is rotated to make the upper surface of the bolt again abut against the lower surface of the outer periphery of the follower 51, and the position adjustment of the follower 51 is completed.

[0047] Furthermore, the driving component 4 also includes a connecting rod 45, which is fixedly connected to the support rods 43 on multiple columns 1, and can drive multiple gears / arc gear ring structures to rotate through a driving source, thereby adjusting the angle of the photovoltaic component on the bracket.

[0048] In the present invention, the supporting component 3 makes the linkage rod 45 offset to one side of the column 1 to avoid interference with the column 1 and avoid passing through the column 1, thereby improving the stability of the column 1 and reducing the difficulty of manufacturing and installation.

[0049] Furthermore, the driving source may be a motor or manpower.

[0050] The present invention also discloses a second embodiment of the adjustable bracket, such as Figure 7 As shown, the second embodiment is different from the first embodiment in that:

[0051] In Example 1, a main beam 2 is provided, and the main beam 2 is rotatably supported on the top ends of multiple columns 1. Multiple purlins 6 perpendicular to the main beam 2 are fixed on the main beam 2, and the photovoltaic module 7 is fixed on a bracket constructed by the main beam 2 and multiple purlins 6.

[0052] In Example 2, the upper end of each column 1 is rotatably supported with a main beam 2, and multiple cross beams 8 perpendicular to the main beams 2 are fixed on the multiple main beams 2, and the photovoltaic module 7 is fixed on a bracket constructed by the main beams 2 and the cross beams 8.

[0053] In Example 1, the arc-shaped gear ring 42 is fixedly connected to the main beam 2 via a connecting rod 44 . In Example 2, both ends of the arc-shaped gear ring 42 are directly fixed to the main beam 2 .

[0054] The above embodiments are only used to illustrate the present invention but not to limit the technical solutions described in the present invention. The understanding of this specification should be based on the technicians in the relevant technical field. For example, the directional descriptions such as "front", "back", "left", "right", "up", and "down" are described in detail in this specification with reference to the above embodiments. However, ordinary technicians in this field should understand that technicians in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
