[0038] In the following, the description will be made with reference to the orientation state of the photovoltaic bracket during actual use.

[0039] Main references Figure 1 , Figure 2 and Figure 8 The present invention discloses a photovoltaic bracket, including a column 1, a main beam 2, a cross beam 3, a transmission mechanism 4, a braking mechanism 5 and a mounting mechanism 6.

[0040] There are multiple columns 1, the lower end of each column 1 is fixed to the surface of the target object (such as the ground), and the upper end of each column 1 is rotatably supported by a main beam 2. Two crossbeams 3 are provided, which are fixedly connected to the two ends of the multiple main beams 2. Purlins 9 are generally fixed on the upper side of the crossbeam 3, and photovoltaic modules 10 are fixed on the upper side of the purlin 9. Compared with the single crossbeam structure, the aforementioned double crossbeam is set up in a double-point support manner, and the photovoltaic modules 10 will be laid more smoothly.

[0041] The main beam 2 is rotatably supported on the column 1 through a pin shaft. The column 1 and the main beam 2 are connected in this way, which has a simple structure and is easy to install.

[0042] See also Figure 3 The photovoltaic bracket also includes an auxiliary support plate 7, and the auxiliary support plate 7 includes a first auxiliary support plate 71 and a second auxiliary support plate 72.

[0043] In the illustrated embodiment, the first auxiliary support plate 71 is perpendicular to the main beam 2, and the center line of the first auxiliary support plate 71 passes through the rotation center of the main beam 2. When viewed along the direction of the center line of the first auxiliary support plate 71, one end of the first auxiliary support plate 71 is fixedly connected to the main beam 2, and the other end is fixedly connected to one end of the arc gear ring 41 in the transmission mechanism 4.

[0044] One end of the second auxiliary support plate 72 is fixed to the main beam 2, and the other end is fixedly connected to the first auxiliary support plate 71. The first auxiliary support plate 71, the second auxiliary support plate 72 and the main beam 2 form a triangular structure, which is more stable.

[0045] In addition, the first auxiliary support plate 71 and the second auxiliary support plate 72 are respectively welded to the main beam 2, and the first auxiliary support plate 71 and the second auxiliary support plate 72 are also fixed by welding, which reduces the number of connecting parts and makes installation easier.

[0046] In the illustrated embodiment, the auxiliary support plate 7 includes a first auxiliary support plate 71 and a second auxiliary support plate 72 . In other embodiments of the present invention, the auxiliary support plate 7 may also include only the first auxiliary support plate 71 .

[0047] Main references Figure 2 , Figure 5 and Fig. 9 The transmission mechanism 4 mainly includes an arc-shaped ring gear 41, a gear assembly 42 and a transmission shaft 43.

[0048] The gear assembly 42 is movably mounted to the column 1 along the radial line β of the arc-shaped gear ring 41 through the mounting mechanism 6 .

[0049] For details, see Fig.14 and Fig.15 The mounting mechanism 6 includes a mounting seat 61 and a guide member 62 .

[0050] The mounting base 61 is U-shaped and includes a first bottom plate 611 and first side plates 612 extending vertically from two sides of the first bottom plate 611. The mounting base 61 is fixed to the column 1.

[0051] The guide member 62 includes a first roller 621 , a second roller 622 , a third roller 623 and a fourth roller 624 .

[0052] The first roller 621, the second roller 622, the third roller 623 and the fourth roller 624 are supported at both ends on the two first side plates 612 respectively, the first roller 621 and the second roller 622 form one row, the third roller 623 and the fourth roller 624 form another row, and a channel α is defined between the two rows of rollers and the two first side plates 612, and the center line γ of this channel α passes through the rotation center of the arc gear ring 41 (which is also the center of its circle).

[0053] Optionally, a sleeve is provided on the outer periphery of the first roller 621, the second roller 622, the third roller 623 and the fourth roller 624. When the sleeve is provided on the outer periphery of the first roller 621, the second roller 622, the third roller 623 and the fourth roller 624, both ends of the first roller 621, the second roller 622, the third roller 623 and the fourth roller 624 are fixed on the two first side plates 612 respectively. It should be understood that when the outer circumference of the first roller 621, the second roller 622, the third roller 623 and the fourth roller 624 is not sleeved with a shaft sleeve, the two ends of the first roller 621, the second roller 622, the third roller 623 and the fourth roller 624 can be respectively fixed to the two first side plates 612. At this time, when the gear assembly 42 moves in the channel α, there is sliding friction between the gear assembly 42 and the rollers; the two ends of the first roller 621, the second roller 622, the third roller 623 and the fourth roller 624 can also be rotatably supported on the two first side plates 612. At this time, when the gear assembly 42 moves in the channel α, there is rolling friction between the gear assembly 42 and the rollers.

[0054] In the illustrated embodiment, each row of rollers includes two rollers. In other embodiments of the present invention, each row of rollers may also include more rollers.

[0055] In the illustrated embodiment, rollers are used to guide the gear assembly 42 . In other embodiments of the present invention, a guide block may be provided between the two first side plates 612 , and the guide block and the two first side plates 612 define a channel α.

[0056] In the illustrated embodiment, the mounting seat 61 is in a "U" shape. In other embodiments of the present invention, the mounting seat 61 may also be in an "L" shape.

[0057] Main references Figures 5 to 12The gear assembly 42 includes a gear 421 , a stopper 422 , a gear seat 423 and a first shaft sleeve 424 .

[0058] The gear seat 423 is in a "U" shape, and has a second bottom plate 4231 and a second side plate 4232. The two second side plates 4232 extend from both sides of the second bottom plate 4231 in a direction perpendicular to the second bottom plate 4231. Optionally, the upper parts of the two second side plates 4232 are fixedly connected to each other by pins, so as to prevent the gear 421 from falling off due to the enlargement of the upper end opening of the gear seat 423 during use, and ensure that the gear 421 is reliably arranged in the gear seat 423.

[0059] The gear seat 423 also has a sleeve mounting hole 4233 (see Fig.11 ), the limit member mounting hole 4234 and the first avoidance hole 4235.

[0060] The sleeve mounting hole 4233 vertically penetrates the two second side plates 4232 and is coaxially arranged with the gear 421. The stopper mounting hole 4234 vertically penetrates the two second side plates 4232, and the stopper 422 is supported on the two second side plates 4232 via a rotating shaft arranged in the stopper mounting hole 4234.

[0061] The first avoidance hole 4235 penetrates at least one second side plate 4232, so that the brake member can be inserted into the first brake hole 415 on the arc gear ring 41 through the first avoidance hole 4235, thereby braking the arc gear ring 41. This is a braking method in the photovoltaic bracket of the present invention. It should be understood that the corresponding positions of the two first side plates 612 are provided with third avoidance holes 613 to facilitate the insertion of the brake member.

[0062] Observing along the radial direction of the arc-shaped gear ring 41, the stopper 422 is located on the side of the arc-shaped gear ring 41 opposite to the gear 421, that is, the arc-shaped gear ring 41 is arranged between the gear 421 and the stopper 422, the toothed structure on the upper part of the arc-shaped gear ring 41 is meshed with the gear 421, and the bottom is in contact with the stopper 422, and the stopper 422 provides support force for the arc-shaped gear ring 41. The distance between the gear 421 and the stopper 422 limits the distance that the gear 421 can move relative to the arc-shaped gear ring 41, thereby ensuring the effective meshing between the arc-shaped gear ring 41 and the gear 421 to avoid tooth disengagement. In the illustrated embodiment, the stopper 422 includes a roller 4221 and a second sleeve 4222. The roller 4221 is rotatably supported on the gear seat 423 through a rotating shaft provided in the stopper mounting hole 4234; the second sleeve 4222 is fixed on the outer periphery of the roller 4221. In the illustrated embodiment, the second sleeve 4222 and the roller 4221 are integrally formed. The outer peripheral surface of the second sleeve 4222 is close to or against the arc-shaped gear ring 41. When the arc-shaped gear ring 41 rotates around its rotation center (which is also the rotation center of the main beam 2) driven by the gear 421, the second sleeve 4222 moves with the arc-shaped gear ring 41. The second sleeve 4222 has a supporting and limiting effect on the arc-shaped gear ring 41, and there is rolling friction between the second sleeve 4222 and the arc-shaped gear ring 41.

[0063] In other embodiments of the present invention, the second shaft sleeve 4222 may also be sleeved on the outer circumference of the roller 4221 , and may or may not be able to rotate relative to the roller 4221 .

[0064] Optionally, the material of the second sleeve 4222 is plastic. It should be understood that when the second sleeve 4222 and the roller 4221 are integrally formed, the second sleeve 4222 and the roller 4221 can both be plastic. The plastic sleeve can further reduce the wear on the arc gear ring 41 and protect the waterproof and anti-corrosion coating on the arc gear ring 41.

[0065] In other embodiments of the present invention, the stopper 422 may also include only the roller 4221, and the two ends of the roller 4221 are fixedly supported on the gear seat 423 or rotatably supported on the gear seat 423 through the stopper mounting holes 4234. When the two ends of the roller 4221 are fixedly supported on the gear seat 423, there is sliding friction between the arc-shaped gear ring 41 and the roller 4221; when the two ends of the roller 4221 are rotatably supported on the gear seat 423, there is rolling friction between the arc-shaped gear ring 41 and the roller 4221.

[0066] In other embodiments of the present invention, the stopper 422 may also be a follower gear (not shown). When the stopper 422 is a follower gear, the arc-shaped gear ring 41 should be provided with teeth that mesh with the follower gear. When the arc-shaped gear ring 41 rotates around its rotation center driven by the gear 421, the follower gear rotates with the arc-shaped gear ring 41.

[0067] In other embodiments of the present invention, the function of the stopper 422 can also be achieved by the second bottom plate 4231. For example, the second bottom plate 4231 has an arc surface, and the top of the arc surface is close to or against the arc gear ring 41. At this time, there is sliding friction between the arc gear ring 41 and the second bottom plate 4231.

[0068] Both ends of the gear 421 are sleeved on the first sleeve 424, and the first sleeve 424 is fixed to the sleeve mounting hole 4233, thereby realizing that the gear 421 is rotatably supported on the gear seat 423. Optionally, the first sleeve 424 is a copper sleeve. The copper sleeve has better wear resistance. Specifically, one end of the first sleeve 424 is sleeved in the center hole 4214 of the gear 421, and the limiting boss at the other end is against the outside of the second side plate 4232. Preferably, a protrusion (not shown in the figure) is also provided on the limiting boss of the first sleeve 424, and a groove corresponding to the protrusion is provided on the second side plate 4232. When the first sleeve 424 is assembled, the protrusion on the limiting boss is located in the groove on the second side plate 4232, thereby realizing the circumferential limitation of the first sleeve 424. The gear 421 is a double gear, which includes a first gear 4211, a second gear 4212, and a gear shaft 4213 extending between the first gear 4211 and the second gear 4212, that is, the first gear 4211 and the second gear 4212 are respectively arranged on both sides of the gear shaft 4213. The tooth top circles of the first gear 4211 and the second gear 4212 are consistent with the outer circumference of the gear shaft 4213. This arrangement allows the gear shaft 4213 to limit the arc-shaped gear ring 41 in the axial direction (the axial direction of the arc-shaped gear ring or the gear). Observed along the axial direction, one side of the arc-shaped gear ring 41 is the gear shaft 4213, and the other side is the second side plate 4232, which form an axial limit for the arc-shaped gear ring 41.

[0069] The gear 421 is a hollow gear, and the transmission shaft 43 passes through the center hole 4214 of the gear 421 and is fixedly connected to the gear 421. In the illustrated embodiment, threaded holes (not marked) are correspondingly provided on the gear shaft 4213 and the transmission shaft 43, and the drilling direction of the aforementioned threaded holes is perpendicular to the axis direction of the gear shaft 4213. The bolts are screwed through the threaded holes to fix the gear shaft 4213 and the transmission shaft 43. The larger diameter of the gear shaft 4213 mentioned above makes the threaded hole located at the gear shaft 4213 have sufficient depth, thereby making the threaded connection between the gear shaft 4213 and the transmission shaft 43 have sufficient strength. When the angle of the photovoltaic bracket needs to be adjusted, the transmission shaft 43 is driven to rotate manually or electrically, and the transmission shaft 43 drives the gear 421 to rotate, thereby driving the arc gear ring 41 to rotate, and the arc gear ring 41 then drives the main beam 2 and the photovoltaic assembly 10 arranged on the main beam 2 to rotate.

[0070] To achieve the fixation of the transmission shaft 43 and the gear 421, the mounting seat 61 also includes a transmission shaft mounting hole 615. The transmission shaft 43 passes through the transmission shaft mounting hole 615 and the center hole 4214 of the gear 421 and is fixedly connected to the gear 421. In order to adapt to the movement of the gear assembly 42, the transmission shaft mounting hole 615 is a waist-shaped hole.

[0071] The transmission shaft 43 is connected to the driving source power, and can drive the gear 421 to rotate. In the illustrated embodiment, each column 1 supports a gear assembly 42, and the transmission shaft 43 passes through the gear 421 supported on each column 1, transmits power to the gear assembly 42 on each column 1, and then drives the main beam 2 supported on each column 1 to rotate.

[0072] When the main beam 2 needs to be rotated, it can be rotated manually or driven by a motor. When the main beam 2 does not need to be rotated, the external force is removed. The transmission shaft 43 in the present invention can be used to transmit power, but does not play a braking role.

[0073] Main references Figures 3 to 5 as well as Figure 8 , the arc-shaped ring gear 41 meshes with the gear 421 for transmission. The arc-shaped ring gear 41 is one-quarter of the arc length. In actual applications, due to factors such as processing and installation requirements, the arc-shaped ring gear 41 is slightly longer or shorter, which are all within the scope of protection of the present invention. One end of the arc-shaped ring gear 4 is fixedly connected to the main beam 2, and the other end is fixed to the end of the first auxiliary support plate 71 away from the main beam 2. The rotation of the arc-shaped ring gear 41 can drive the main beam 2 to rotate around the column 1, and then drive the photovoltaic assembly 10 to rotate around the column 1, so that the photovoltaic assembly 10 can receive sunlight at different angles.

[0074] Specifically, the arc-shaped gear ring 41 has double rows of teeth, and the double rows of teeth are both on the inner side of the arc-shaped gear ring 41. The double rows of teeth of the arc-shaped gear ring 41 are meshed with the first gear 4211 and the second gear 4212 for transmission.

[0075] The cross section of the arc gear ring 41 is in a “U” shape. The arc gear ring 41 comprises an arc bottom plate 411 , a fourth side plate 412 , teeth 413 , a water leakage hole 414 and a first braking hole 415 .

[0076] The two fourth side plates 412 extend from opposite sides of the arc-shaped bottom plate 411 in a direction perpendicular to the arc-shaped bottom plate 411. A plurality of teeth 413 are arranged on the top of the two fourth side plates 412 for meshing with the gear 421 for transmission.

[0077] A plurality of water leakage holes 414 are located on the arc bottom plate 411, and the water leakage holes 414 penetrate the arc bottom plate 411. The number and position of the water leakage holes 414 correspond to the angle that the photovoltaic bracket needs to be adjusted. At the target angle, at least one water leakage hole 414 is located at the bottom of the entire arc gear ring 41 to ensure that wind, sand and rain fall off.

[0078] The arc-shaped gear ring 41 is formed by bending a sheet metal part, which has a simple process and low cost.

[0079] One end of the arc-shaped gear ring 41 is fixed to the main beam 2 through a waist-shaped hole. Figure 3 and Figure 4 The photovoltaic bracket has a connecting block 8. The connecting block 8 is welded and fixed to the main beam 2, and a waist-shaped hole or a round hole is provided on the connecting block 8. Correspondingly, a round hole or a waist-shaped hole is provided on the arc-shaped gear ring 41. Bolts pass through the waist-shaped hole on the connecting block 8 and the round hole on the arc-shaped gear ring 41, or bolts pass through the round hole on the connecting block 8 and the waist-shaped hole on the arc-shaped gear ring 41 to fix the two. The use of the waist-shaped hole allows the arc-shaped gear ring 41 to have a certain adjustable space relative to the main beam 2, so as to absorb the manufacturing error of the arc-shaped gear ring 41 to a certain extent and complete the installation of related components.

[0080] Compared with the common semi-circular arc structure, the arc gear ring 41 is set to about one-quarter of the arc length. On the one hand, it can save materials and reduce costs. On the other hand, at some angles, the end of the arc gear ring 41 is located at the bottom of the entire arc gear ring 41, which is convenient for the falling of wind, sand and rain.

[0081] The first braking hole 415 is spaced apart from the arc-shaped gear ring 41. The first braking hole 415 penetrates the two fourth side plates 412 in a direction perpendicular to the fourth side plate 412. It should be understood that the position of the first braking hole 415 corresponds to the angle to which the photovoltaic bracket needs to be adjusted. When the photovoltaic bracket is adjusted to the target angle, the annular gear ring 41 can be fixed relative to the mounting seat 61 by passing a bolt or a similar rod-shaped member through the third avoidance hole 613, the first avoidance hole 4235 and the first braking hole 415 to achieve braking. In the photovoltaic bracket disclosed in the present invention, this braking method can coexist with the braking method using the braking mechanism 5 mentioned below, or one of the two can be selected. When the two methods of braking using the first braking hole 415 and braking using the braking mechanism 5 coexist, the braking method of the photovoltaic bracket has more choices.

[0082] Main references Figure 8 and Fig.13 The brake mechanism 5 includes a brake support seat 51, a brake block 52 and a rod-shaped brake member 53 (see Figure 3 ).

[0083] The brake support seat 51 is in a U-shape, and includes a third bottom plate 511 and a third side plate 512. The third side plate 512 extends from both sides of the third bottom plate 511 in a direction perpendicular to the third bottom plate 511.

[0084] The third bottom plate 511 is fixed to the first bottom plate 611 of the mounting seat 61. The brake support seat 51 has a second avoidance hole 513, and the second avoidance hole 513 penetrates the two third side plates 512 in a direction perpendicular to the third side plates 512. The arc gear ring 41 passes through the two second avoidance holes 513.

[0085] The brake block 52 includes a brake block body 521, a tooth portion 522 and a grip portion 523. The brake block 52 is disposed in the brake support seat 51, and the two third side plates 512 respectively contact the two sides of the brake block 52 to limit the brake block 52 in the rotation direction of the arc gear ring 41.

[0086] The brake block body 521 has a second brake hole 5211. The second brake hole 5211 passes through or does not pass through the brake block body 521, and one end of the rod-shaped brake member 53 passes through the second brake hole 5211. Corresponding to the second brake hole 5211, the mounting seat 61 has a fourth avoidance hole 614, and the fourth avoidance hole 614 passes through the two first side plates 612 in a direction perpendicular to the two first side plates 612. The tooth portion 522 and the grip portion 523 are respectively located at both ends of the brake block body 521. When the transmission mechanism 4 rotates the photovoltaic bracket to the target angle, the operator holds the grip portion 523 to place the brake block 52 into the brake support seat 51 and engages with the arc-shaped gear ring 41. Subsequently, the operator passes the rod-shaped brake member 53, such as a bolt, through the fourth avoidance hole 614 and the second brake hole 5211 to brake the arc-shaped gear ring 41.

[0087] When the braking mechanism 5 is selected for braking, the braking of the gear ring 41 by the braking mechanism 5 is stepless. Specifically, when the angle of the photovoltaic component 10 needs to be adjusted, the arcuate gear ring 41 can be rotated to any angle and then braked by the tooth portion 522 and the rod-shaped brake member 53 on the braking mechanism 5. Compared with the method of adjusting the angle of the photovoltaic component 10 by arranging a plurality of first braking holes 415 at intervals on the arcuate gear ring 41, the braking mechanism 5 can overcome the defect that the first braking hole 415 can only adjust the set angle, thereby realizing the adjustment of the photovoltaic component 10 to any angle, which is flexible and convenient.

[0088] In the illustrated embodiment, the third bottom plate 511 of the brake support seat 51 is fixed to the mounting seat 61, and the brake support seat 51 limits the brake block 52 through its own third side plate 512 and the first side plate 612 of the mounting seat 61, thereby braking the arc gear ring 41 through the brake block 52.

[0089] In other embodiments of the present invention, the brake support seat 51 is not fixed in the mounting seat 61. It should be understood that the brake support seat 51 is still directly or indirectly fixed to the column 1.

[0090] At this time, the brake support seat 51 also has two other side plates perpendicular to the third side plate 512. When the arc gear ring 41 needs to be braked, the rod-shaped brake member 53 passes through the other two side plates and the second brake hole 5211 to achieve braking.

[0091] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, the ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements thereof 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.
