[0050] Currently, the driving members 2 in the single-axis tracking type photovoltaic support 1 correspond one-to-one with the photovoltaic modules 7. Each driving member 2 is used to drive a photovoltaic module 7 to rotate, so as to adjust the angle of the photovoltaic module 7 to obtain a higher solar radiation utilization rate. This design method in which the driving members 2 and the photovoltaic modules 7 correspond one-to-one makes the production cost and the later use cost of the current single-axis tracking type photovoltaic support 1 relatively high.

[0051] After in-depth research, the inventor found that the driving member 2 can be used to drive the rotating member 3 to rotate, driving two sliders 4 to slide on a photovoltaic module 7 respectively, so that the two photovoltaic modules 7 can rotate synchronously by the same angle, that is, the angles of the two photovoltaic modules 7 can be synchronously adjusted by one driving member 2 to reduce the cost.

[0052] Embodiment 1

[0053] As Figure 1As shown in the figure, Embodiment 1 of the present application provides a single-axis tracking type photovoltaic support structure, including:

[0054] A bracket 1 having two mounting positions arranged at intervals in a first direction, and each mounting position of the bracket 1 is used for rotatably connecting a photovoltaic module 7 about a second direction;

[0055] A driving member 2 located between the two mounting positions, and the driving member 2 is connected to the bracket 1;

[0056] A rotating member 3 connected to the driving end of the driving member 2;

[0057] Two sliders 4, each side of the rotating member 3 in the first direction is rotatably connected to a slider 4 about the second direction, the driving member 2 is located between the two sliders 4, and each of the two sliders 4 is used for slidably connecting to a photovoltaic module 7 in the first direction;

[0058] Wherein, the driving member 2 drives the rotating member 3 to rotate about the second direction, driving the two sliders 4 to slide in the first direction, so that the two photovoltaic modules 7 rotate synchronously about the second direction by the same angle, and the first direction is perpendicular to the second direction.

[0059] Specifically, the bracket 1 is used to support and connect the photovoltaic module 7. The specific structure of the bracket 1 is not further limited and can be specifically designed according to actual needs. The two mounting positions can be opposite or facing each other in the first direction, and the mounting position of the bracket 1 can be rotatably connected to the photovoltaic module 7 about the second direction through pin connection or hinge connection.

[0060] The driving member 2 is used to drive the rotating member 3 to rotate about the second direction. The driving member 2 can be spaced from the two photovoltaic modules 7 respectively to ensure the smoothness of the entire movement process. The driving member 2 can be connected to the bracket 1 by bolts, snap connection, etc. The driving member 2 can be selected as a motor, a rotary cylinder, etc. The rotation angle of the driving member 2 can be specifically designed according to seasons and the regions of actual application. For example, the rotation angle of the driving member 2 can be ±45°. The driving member 2 is set to stop working at night to reduce the energy consumption of the driving member 2. The driving member 2 can work continuously during the day to adjust the angle in real time, so that the two photovoltaic modules can always face the sun to obtain the best solar radiation utilization rate; or, the driving member 2 can also work at intervals of a preset time during the day, for example, at intervals of 0.5 h or 1 h, etc., to further reduce the energy consumption of the driving member 2. The rotation axis of the rotating member 3 and the rotation axes of the two photovoltaic modules 7 can be in the same plane to ensure the stability of the overall structure.

[0061] The rotating member 3 is used to connect the driving member 2 and the slider 4 to achieve the transmission of force. The rotating member 3 can be fixedly connected to the driving end of the driving member 2 by bolts or snap connection. The rotating member 3 can be a rod-shaped structure; alternatively, the rotating member 3 can also be a plate-shaped structure, etc. In this application, the rotating member 3 is preferably a rod-shaped structure to achieve lightweight design.

[0062] The slider 4 can be pin-connected or hinged to the rotating member 3. The single-axis tracking photovoltaic support structure can also include two guide rails. Each guide rail can be respectively used for being arranged on the back of a photovoltaic module 7, and each guide rail is located on one side of the corresponding photovoltaic module 7 along the second direction. Both the driving member 2 and the rotating member 3 are located on one side of the photovoltaic module 7 along the second direction, and the rotating member 3 can be arranged at an interval from the photovoltaic module 7 to avoid interference between the two. When the driving member 2 drives the rotating member 3 to rotate, the rotating member 3 and the slider 4 are rotationally connected around the second direction to ensure the smooth rotation of the rotating member 3. The length direction of the guide rail is consistent with the first direction, and the slider 4 is slidably connected to the photovoltaic module 7 along the first direction through the guide rail.

[0063] Through the above technical solution, the single-axis tracking photovoltaic support structure provided in Embodiment 1 of the present disclosure realizes the rotational connection of the photovoltaic module 7 by using two installation positions on the bracket 1; the driving member 2 is arranged between the two installation positions and connected to the bracket 1, ensuring the stability of the connection of the driving member 2. When the driving member 2 drives the rotating member 3 to rotate around the second direction, the rotating member 3 can respectively drive the two sliding members to slide along the first direction relative to the corresponding photovoltaic module 7, avoiding interference between the rotating member 3 and the photovoltaic module 7 during the rotation process of the rotating member 3, and realizing the synchronous rotation of the two photovoltaic modules 7 by the same angle around the second direction, that is, the synchronous adjustment of the two photovoltaic modules 7 is realized by one driving member 2, which not only ensures that both photovoltaic modules 7 can obtain a higher solar radiation utilization rate and improve the energy conversion efficiency, but also greatly reduces the production cost.

[0064] As Figures 1 to 5 shown, in some embodiments, it further includes:

[0065] Two mounting brackets 5, arranged at intervals along the first direction; at each installation position of the bracket 1, a photovoltaic module 7 can be rotationally connected to a mounting bracket 5 around the second direction.

[0066] Both of the two mounting brackets 5 are provided with sliding grooves 51 extending along the first direction. Each slider 4 is slidably connected to a mounting bracket 5 along the first direction through the sliding groove 51, and each sliding groove 51 is located in the middle of the corresponding mounting bracket 5 along the second direction.

[0067] Specifically, the mounting bracket 5 can be rotatably connected to the bracket 1 about the second direction by pin connection or hinge connection. The mounting bracket can be a frame structure, a plate-like structure, or the like. The first surface of the mounting bracket 5 can be connected to the back surface of the photovoltaic module 7 by means of snap connection, bolt connection, etc. A slideway 51 is provided on the second surface of the mounting bracket 5 opposite to the first surface. For example, a guide rail can be provided on the second surface of the mounting bracket 5, and the guide rail forms the slideway 51; alternatively, a strip-shaped groove can also be opened on the second surface of the mounting bracket 5, and the length direction of the strip-shaped groove is the same as the first direction. The slider 4 is slidably connected to the mounting bracket 5 along the first direction through the strip-shaped groove, and the strip-shaped groove forms the slideway 51. The mounting bracket 5 can provide an additional support point for the photovoltaic module 7, increasing the stability of the entire structure; and, the mounting bracket 5 can also help disperse the weight of the photovoltaic module 7, thereby extending the service life of the support structure.

[0068] As Figure 3 shown, the slideways 51 can all be located on one side of the corresponding mounting bracket 5 along the second direction. Both the driving member 2 and the rotating member 3 are located on one side of the photovoltaic module 7 along the second direction. The rotating member 3 can be arranged at an interval from the mounting bracket 5 to avoid interference between the two and ensure the smooth rotation of the rotating member 3; or, the slideways 51 can all be located in the middle of the corresponding mounting bracket 5 along the second direction, so that the force on the mounting bracket 5 is more uniform.

[0069] Set the side surfaces of the two mounting brackets 5 close to each other as the first side surfaces. When the slideways 51 are all located in the middle of the corresponding mounting brackets 5 along the second direction, as Figure 4 shown, partial first side surfaces of the mounting brackets 5 can all be recessed inward to form avoidance grooves 52, and the avoidance grooves 52 extend from the first surface to the second surface of the mounting brackets 5. Among them, the slideways 51 can be located on one side of the avoidance grooves 52 of the mounting brackets 5 along the second direction. When the driving member 2 drives the rotating member 3 to rotate, part of the rotating member 3 can pass through the avoidance grooves 52 and be rotatably connected to the slider 4 about the second direction to ensure the smooth rotation of the rotating member 3; or, as Figure 5 shown, partial first side surfaces of the mounting brackets 5 can all protrude outward to form mounting portions 53. Each mounting portion 53 is located in the middle of the corresponding mounting bracket 5 along the second direction, and the slideways 51 are arranged on the mounting portions 53. When the driving member 2 drives the rotating member 3 to rotate, part of the rotating member 3 is located on one side of the mounting portion 53 along the second direction and is rotatably connected to the slider 4 about the second direction.

[0070] As Figures 1 to 5As shown, in some embodiments, the two mounting brackets 5 face each other in the first direction to simplify the installation process. And / or, the rotation axes of the two mounting brackets 5 and the rotation axis of the rotating member 3 are in the same plane to ensure the smoothness during the rotation process, reduce the friction and resistance during the rotation process, and improve the stability and reliability of the support mechanism. And / or, the driving member 2 is connected to the middle part of the rotating member 3 in the first direction to provide a better torque distribution, make the rotating member 3 rotate more evenly and stably, reduce the unbalanced forces at both ends of the rotating member 3, and make the driving force transmission of the driving member 2 more direct and efficient.

[0071] As Figure 1 and Figure 2 shown, in some embodiments, the bracket 1 includes:

[0072] Two first sub-brackets 11 are arranged at intervals in the first direction, and each mounting bracket 5 is rotatably connected to a first sub-bracket 11 around the second direction;

[0073] A second sub-bracket 12 is located between the two first sub-brackets 11, and the driving member 2 is connected to the second sub-bracket 12.

[0074] Specifically, the second sub-bracket 12 and the two first sub-brackets 11 can be independently arranged to simplify the support structure, so that each part can be installed and maintained separately, thereby reducing the overall complexity; or, the second sub-bracket 12 can be connected to at least one first sub-bracket 11 by bolts or snap connections to improve the stability of the support structure and reduce the displacement or vibration that may occur during operation.

[0075] As Figure 1 and Figure 2 shown, in some embodiments, the second sub-bracket 12 is configured with an arc-shaped chute 1221; a part of the rotating member 3 protrudes outward to form a protruding portion, and the protruding portion is adapted to the chute 1221, and the rotation of the rotating member 3 can make the protruding portion slide in the chute 1221.

[0076] Specifically, the cooperation between the arc-shaped chute 1221 and the protruding portion restricts the movement trajectory of the rotating member 3, and at the same time provides a stable support point for the rotating member 3, improving the stability of the support structure. The number of protruding portions can be one or more, such as two, three, four, etc. When there are two protruding portions, the two protruding portions can be respectively located on both sides of the driving member 2. At this time, there can be two arc-shaped chutes 1221, and the two arc-shaped chutes 1221 can be arranged at intervals in the first direction, and each protruding portion can slide in one chute 1221 to enhance the stability of the support structure.

[0077] As Figure 1 and Figure 2 shown, in some embodiments, the second sub-bracket 12 includes:

[0078] The support component 121 is located between the two first sub - brackets 11, and the driving member 2 is disposed on the support component 121;

[0079] The fixing member 122 is connected to the support component 121; the fixing member 122 is configured with a chute 1221; the fixing member 122 has a first end face and a second end face facing away from each other in the third direction, the first end face is closer to the bearing surface where the support component 121 is located than the second end face, and the first end of the chute 1221 extends to the first end face; the first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0080] Specifically, since the first end of the chute 1221 extends to the first end face of the fixing member 122, the chute 1221 forms a drainage channel, and when rainwater flows along the chute 1221, it can be guided by gravity to drain from the first end of the chute 1221, preventing water accumulation in the chute 1221 and extending the service life of the support structure.

[0081] Such as Figure 2 shown, in some embodiments, it further includes:

[0082] Two first telescopic sleeves 6, each first telescopic sleeve 6 is connected to a first sub - bracket 11, and the first telescopic sleeve 6 is used to adjust the distance between the mounting frame 5 and the bearing surface where the first sub - bracket 11 is located.

[0083] Specifically, the first end of the first telescopic sleeve 6 can be connected to the first sub - bracket 11 by bolts or snap - connection, or the first telescopic sleeve 6 can form the first sub - bracket 11 to simplify the overall structure and reduce costs. The first telescopic sleeve 6 can be obtained by purchasing in the market.

[0084] When the second sub - bracket 12 is connected to a first sub - bracket 11, a first telescopic sleeve 6 can be connected to the second sub - bracket 12 through the first sub - bracket 11, thereby synchronously adjusting the distance between the driving member 2 and the bearing surface where the first sub - bracket 11 is located.

[0085] When the second sub - bracket 12 and the two first sub - brackets 11 are independently arranged, the support structure can further include a second telescopic sleeve, and the second telescopic sleeve is connected to the second sub - bracket 12, and the second telescopic sleeve is used to adjust the distance between the driving member 2 and the bearing surface where the second sub - bracket 12 is located.
