Description

solar module system

[0001] The present invention relates to a solar module system, and more specifically, to a solar module system capable of rotating a plurality of solar modules at once.

[0002] A conventional single-axis solar tracker is manufactured in a form in which a number of posts for supporting solar modules are mounted vertically on the ground, a single rotating shaft is provided that is rotatably supported by the posts, and the solar modules are supported on the upper side of the rotating shaft.

[0003] The single-axis solar tracker ensures that sunlight is incident perpendicularly on the solar module by turning the solar module toward the sun from sunrise to sunset by rotating the rotation shaft.

[0004] However, while conventional single-axis solar trackers were manufactured assuming a flat ground, in actual use environments, solar power facilities were installed to accommodate ground with varying heights, slopes, or uneven ground.

[0005] Therefore, in the case of a single-axis solar tracker, solar modules are rotated through a single rotation shaft, but rotating multiple solar modules all at once with a single rotation shaft due to variations in ground height and slope caused problems such as errors in the rotation angle of each solar module and deterioration of the durability of the solar device.

[0006] To solve these problems, technologies have recently been developed to rotate solar modules by installing multiple actuators on single-axis solar trackers. However, since these technologies install a separate motor for each actuator and apply voltage to the motor individually, individual control of each motor is required, and there is a difficulty in controlling each motor simultaneously to rotate the solar modules to the same angle.

[0010] The present invention aims to solve the above problems by providing a solar power generation system that enables the rotation angle adjustment of solar modules to be performed effectively and collectively even on ground with varying heights or slopes.

[0011] A solar module system according to one embodiment of the present invention comprises: a main frame portion on which a solar panel is mounted and which can rotate with respect to a longitudinal axis; a support frame portion installed on the lower side of the main frame portion and supporting the main frame portion from the ground; a plurality of angle adjustment portions installed on the support frame portion and adjusting the longitudinal center rotation angle of the main frame portion; a driving member formed on the angle adjustment portion located at one end of the longitudinal direction and providing power to the angle adjustment portion and generating power, and a power transmission member that receives power from the driving member and transmits power to the angle adjustment portion through rotation, and a limiter portion connected to the power transmission member and controlling the rotation of the power transmission member to control the rotation angle of the angle adjustment portion.

[0012] In one embodiment, the angle adjustment unit may include an auxiliary support member fixedly coupled to the main frame member and linked with the movement of the main frame member, and an actuator member coupled to the auxiliary support member and the support frame member and rotated the main frame member by moving the auxiliary support member through linear motion.

[0013] In one embodiment, the power transmission member may include a first rotating shaft that is rotated by power provided from the power unit, a first bevel gear that is fitted and coupled to one side of the first rotating shaft and rotates together with the first rotating shaft to transmit power to the actuator unit, and a first gear that is fitted and coupled to the other side of the rotating shaft and rotates together with the first rotating shaft.

[0014] In one embodiment, the limiter portion may include a second gear formed to mesh with the first gear and rotate together with the first gear, a second rotating shaft having screw threads formed on its outer surface and extending in one direction so that the second gear is fitted and coupled to one end, a locking member fitted and screw-coupled to the second rotating shaft and rotating together with the rotation of the second rotating shaft to change position, and a pair of stoppers located on both sides of the locking member adjacent to the second rotating shaft, having a size sufficient to restrict movement by the locking member, and spaced apart from each other by a predetermined distance.

[0015] In one embodiment, the actuator part may include a second bevel gear that meshes vertically with the first bevel gear at the top.

[0016] In one embodiment, as the locking member is caught on one of the pair of stoppers and movement is restricted, the rotation of the second rotating shaft and the second gear is stopped, and as the rotation of the second gear is stopped, the rotation of the first gear, the first rotating shaft, and the first bevel gear is also stopped, thereby restricting the linear movement of the actuator part.

[0017] In one embodiment, the linear movement of the actuator part can be controlled by adjusting the distance between the pair of stoppers, thereby controlling the rotation angle of the angle adjustment part.

[0018] In one embodiment, the main frame portion includes a plurality of unit main frames connected to each other in the longitudinal direction and a first joint portion formed between the unit main frames so that the unit main frames are positioned parallel to the ground by adjusting the angle between the unit main frames; and the support frame portion may include a plurality of unit support frames installed on the lower side of the unit main frame to support the unit main frame from the ground, and a rotational support portion coupled to the upper end of the unit support frames to enable the unit main frame to rotate axially.

[0019] In one embodiment, the angle adjustment unit may be installed on some or all of the plurality of unit support frames, and may be installed on the unit support frame located at one end in the longitudinal direction.

[0020] In one embodiment, the auxiliary support member is fixedly coupled to the unit main frame and the rotational support member and is linked to the movement of the unit main frame, and the actuator member is coupled to the auxiliary support member and the unit support frame and can rotate the unit main frame by moving the auxiliary support member through linear motion.

[0021] In one embodiment, the power unit is further included in a power connection formed between the angle adjustment units to transmit power between the angle adjustment units, and the power connection may include a plurality of pipes connecting the hinge portion to which the actuator portion and the auxiliary support portion of the angle adjustment unit are combined, and a second joint portion connecting the pipes.

[0022] The solar module system according to the present invention enables the rotation of a plurality of solar panels arranged in the solar module system collectively through a single power unit via a main frame unit, a power unit, and a power connection unit.

[0023] In particular, the solar module system according to the present invention enables more precise angle control by adjusting the rotation angle of the main frame through the limiter.

[0024] In addition, the solar module system according to the present invention can minimize durability problems that may arise by being manufactured to be rotatable in response to changes in the slope and height of the ground.

[0046]

[0047] First, referring to FIGS. 1 and 2, a solar module system (1) according to an embodiment of the present invention comprises: a main frame portion (100) capable of rotating with the longitudinal direction as a central axis; a support frame portion (200) installed on the main frame portion (100) and having a solar panel (not shown) mounted thereon, and installed on the lower side of the main frame portion (100) and supporting the main frame portion (100) from the ground; a plurality of angle adjustment portions (300) rotating in conjunction with the main frame portion (100); a power portion (400) including a driving member formed on the angle adjustment portion (300) located at one end of the longitudinal direction to provide power to the angle adjustment portion (300) and generate power, and a power transmission member that receives power from the driving member and transmits power to the angle adjustment portion through rotation; and a power transmission member connected to the power transmission member to control the rotation of the power transmission member to control the rotation angle of the angle adjustment portion (300). It includes a limiter unit (500) and a power connection unit (600) formed between the angle adjustment units (300) to transmit power from the power unit (400) to the angle adjustment units (300).

[0048]

[0049] A solar module system (1) according to one embodiment of the present invention includes a main frame part (100), a support frame part (200), an angle adjustment part (300), a power part (400), a limiter part (500), and a power connection part (600).

[0050] Referring to FIG. 1, the main frame portion (100) may be installed so as to be extended in the longitudinal direction and installed parallel to the ground, or it may be formed so as to be spaced apart from the ground at a certain distance. Although not shown, a structural frame portion on which a solar panel is mounted may be formed on the main frame portion (100). The solar panel, the structural frame portion, and the main frame portion (100) rotate together in conjunction with each other.

[0051] The support frame portion (200) performs the role of supporting the main frame portion (100) from the ground. The support frame portion (200) may be extended in one direction to support the main frame portion (100). The support frame portion (200) may be extended vertically with respect to the ground. It may have a shape.

[0052] The angle adjustment unit (300) is coupled to the support frame unit (200) and connected to the support frame (200). The angle adjustment unit (300) is formed to adjust the longitudinal center rotation angle of the main frame unit (100).

[0053] The power unit (400) is formed in the angle adjustment unit (300) located at one end in the longitudinal direction and supplies power to the angle adjustment unit (300). Accordingly, the power unit (400) is located at one end of the solar module system and enables the overall operation of the system through power generation on one side in the longitudinal direction.

[0054] A solar panel mounted on the main frame (100) can be rotated by driving the angle adjustment unit (300) of the present invention. The specific configuration of the angle adjustment unit (300) will be described later.

[0055]

[0056] In a solar module system (1) according to one embodiment of the present invention, the power transmission unit (600) may include a plurality of pipes (610) connecting the actuator unit (320) of the angle adjustment unit (300) and the hinge unit to which the auxiliary support unit (310) is combined, and a second joint unit (620) formed between the pipes (610) to adjust the angle between the pipes (610).

[0057]

[0058] A power transmission unit (600) of a solar module system (1) according to one embodiment of the present invention may include a plurality of pipes (610) and a second joint unit (620).

[0059] A plurality of pipes (610) are configured to connect the hinge portions where the actuator portion (320) and the auxiliary support portion (310) are combined, and the energy of the hinge portion of the actuator portion (320) moving due to the movement of the pipes (610) is transferred to the actuator portion (320) of the adjacent angle adjustment portion (300), so that a plurality of angle adjustment portions (310) can operate in conjunction with each other.

[0060] The second joint section (620) is configured to connect multiple pipes (610), and a universal joint may be used, but is not limited thereto. The second joint section (620) allows the angle between the pipes (610) to be adjusted so as to accommodate a design that bends according to the ground of the main frame section (100).

[0061] The power connection unit (600) is configured to be formed between the angle adjustment units (300) and performs the role of transmitting power from the power unit (400) in the longitudinal direction of the system. The power connection unit (600) may be formed in multiple numbers and arranged in one direction to transmit power between the angle adjustment units (300). The position of the power connection unit (600) changes according to the movement of the angle adjustment unit (300), and accordingly, the position of the angle adjustment unit (300) that is continuously formed in the longitudinal direction can also be changed through the power connection unit (600). By being connected to each of the angle adjustment units (300), the power generated through the power unit (400) at the angle adjustment unit (300) located at one end of the longitudinal direction of the solar module system (1) can be transmitted to each of the angle adjustment units (300).

[0062]

[0063] In a solar module system according to one embodiment of the present invention, the main frame portion (100) may include a plurality of unit main frames (110) that are connected to each other in the longitudinal direction, and a first joint portion (120) formed between the unit main frames (110) so that the unit main frames (110) are arranged parallel to the ground by adjusting the angle between the unit main frames (110).

[0064] Looking at FIG. 1, it can be seen that the main frame portion (100) of a solar module system (1) according to one embodiment of the present invention includes a plurality of unit main frames (110) and a first joint portion (120).

[0065] Multiple unit mainframes (110) are configured to be connected to each other in the longitudinal direction. Since the mainframe section (100) cannot respond to multiple slopes and changes in ground height as a single frame, it is formed with multiple unit mainframes (110).

[0066] The first joint portion (120) is configured to adjust the angle between unit mainframes (110) and may be formed as a universal joint, but is not limited thereto.

[0067]

[0068] In a solar module system according to one embodiment of the present invention, the support frame part (200) may include a plurality of unit support frames (210) installed on the lower side of the unit main frame (110) to support the unit main frame (110) from the ground, and a rotation support part (250) coupled to the upper side of the unit support frame (210) to enable the unit main frame (110) to rotate about an axis.

[0069]

[0070] Referring to FIGS. 1 and 2, the support frame portion (200) of a solar module system (1) according to an embodiment of the present invention may include a unit support frame (210) and a rotational support portion (250). The unit support frame (210) is a column configuration that supports the solar module system (1) by spacing it apart from the ground. As shown in FIG. 1, the rotational support portion (250) is a configuration that surrounds the unit main frame (110) and is coupled to the top of the unit support frame (210). The rotational support portion (250) configuration performs the role of supporting the unit main frame (110) so that it can rotate axially.

[0071]

[0072] In a solar module system (1) according to an embodiment of the present invention, the angle adjustment unit (300) is installed on some or all of the plurality of unit support frames (210), and may be installed on the unit support frame (210) located at one end in the longitudinal direction.

[0073] Looking at FIG. 1, it can be seen that the angle adjustment unit (300) is not installed on all unit support frames (210) but on some of the unit support frames (210). That is, the angle adjustment unit (300) can be installed on some or all of the unit support frames (210) depending on the situation. At this time, the angle adjustment unit (300) must be installed at one end in the longitudinal direction of the main frame part (100) where the power unit (400) is formed, and accordingly, the angle adjustment unit (300) is installed on the unit support frame (210) located at one end in the longitudinal direction.

[0074] The frequency at which the angle adjusting unit (300) is formed in the unit support frame (210) may be formed as 1 to 5 per 10 unit support frames (210). When the frequency of installing the angle adjusting unit (300) is 5 per 10 unit support frames (210), the angle adjusting unit (300) may be installed by skipping each unit support frame (210), and in the case of a design in which many angle adjusting units (300) are formed, it is applied when the slope or height change of the ground is severe. In addition, when the slope or height change of the ground is not severe, the frequency of arranging the angle adjusting unit (300) may be formed as 1 per 10 unit support frames (210).

[0075]

[0076] In a solar module system (1) according to one embodiment of the present invention, the angle adjustment unit (300) may include an auxiliary support unit (310) that is fixedly connected to the unit main frame (110) and the rotation support unit (250) and is linked to the movement of the unit main frame (110), and an actuator unit (320) that is connected to the auxiliary support unit (310) and the unit support frame (210) and moves the auxiliary support unit (310) by a linear motion to rotate the unit main frame (110).

[0077] The angle adjustment unit (300) of the solar module system (1) according to one embodiment of the present invention may include an auxiliary support unit (310) and an actuator unit (320).

[0078] Referring to FIG. 1, the auxiliary support member (310) is fixedly coupled to the unit main frame (110) and the rotational support member (250). The auxiliary support member (310) is configured to move in conjunction with the unit main frame (110). Thus, the unit main frame (110) rotates due to the movement of the auxiliary support member (310).

[0079] The actuator part (320) is coupled to the unit support frame (210) and moves the auxiliary support part (310) by linear motion. The actuator part (320) may be composed of a body (321) and a rod (322), and the auxiliary support part (310) may be moved by linear motion of the rod (322) to rotate the unit main frame (110). A part of the rod (322) may be provided inside the body (321), and a second bevel gear (323) described later may be formed on the upper end of the rod (322).

[0080] The energy for linearly moving the actuator unit (320) can be transmitted through the power unit (400) or the power connection unit (600). The two can be hinge-coupled so that the auxiliary support unit (310) moves by the movement of the actuator unit (320). The auxiliary support unit (310) can be hinge-coupled with the unit support frame (210). That is, one end of the auxiliary support unit (310) can be hinge-coupled with the unit support frame (210), and the other end can be hinge-coupled with the actuator unit (320).

[0081]

[0082] In a solar module system (1) according to one embodiment of the present invention, the power unit (400) is formed in the angle adjustment unit (300) located at one end in the longitudinal direction to provide power to the angle adjustment unit (300). It may include a driving member (410) that generates power and a power transmission member (420) that receives power from the driving member (410) and transmits power to the angle adjustment unit (300) through rotation.

[0083] The power unit (400) of the solar module system (1) according to one embodiment of the present invention is provided inside the case (10). The power unit (400) may include a driving member (410) and a power transmission member (420).

[0084] Referring to FIGS. 2 to 4, the driving member (410) may be a conventional motor that provides power. The power transmission member (420) may be connected to the driving member (410). The power transmission member (420) may include a first rotating shaft (421) that is rotated by power provided from the power unit (400), a first bevel gear (423) that is fitted and coupled to one side of the first rotating shaft (421) and rotates together with the first rotating shaft (421) to transmit power to the actuator unit (320), and a first gear (425) that is fitted and coupled to the other side of the rotating shaft (423) and rotates together with the first rotating shaft (421).

[0085] One end of the first rotating shaft (421) may be positioned close to the actuator part (320). The first bevel gear (423) is formed to mesh vertically with the second bevel gear (323) formed at the top of the actuator part (320). The first bevel gear (423) can transmit power from the power unit (400) to the second bevel gear (323), thereby causing the actuator part (320) to move in a straight line. The first bevel gear (423) and the second bevel gear (323) may be accommodated inside the body (321) as shown in FIG. 2.

[0086]

[0087] The other end of the first rotating shaft (421) can be positioned close to the power unit (400). The first rotating shaft (421) can be rotated by the power of the power unit (400) by being coupled to the power unit (400). The first gear (425) coupled to the first rotating shaft (421) is rotated by the rotation of the first rotating shaft (421), thereby enabling power to be transmitted to the limiter unit (500) described later.

[0088]

[0089] In a solar module system (1) according to one embodiment of the present invention, the limiter portion (500) may include: a second gear (525) formed to mesh with the first gear (425) and rotated together with the first gear (425); a second rotating shaft (521) having screw threads formed on its outer surface and extending in one direction so that the second gear (525) is fitted and coupled to one end; a locking member (527) that is fitted and screw-coupled to the second rotating shaft (521) and rotates together with the rotation of the second rotating shaft (521) to change its position; and a pair of stoppers (529) positioned on both sides of the locking member (527) adjacent to the second rotating shaft, having a size such that the locking member (527) is caught and movement is restricted, and spaced apart from each other by a predetermined distance.

[0090] A limiter unit (500) of a solar module system (1) according to one embodiment of the present invention may be arranged in parallel with a power unit (400). The limiter unit (500) may be provided inside a case (10) together with the power unit (400). The limiter unit (500) may include a second gear (525), a second rotating shaft (521), a locking member (527), and a pair of stoppers (529).

[0091] The second gear (525) is formed to mesh with the first gear (425) coupled to the other end of the first rotation axis. The second gear (525) is formed to mesh with the first gear (425) when the first gear (425) is rotated by the power unit (400), thereby rotating together with the first gear (425).

[0092] The second rotating shaft (521) extends in one direction, and the second gear (525) is fitted into one end. By being coupled with the second gear (525), the second rotating shaft (521) rotates together with the second gear (525) when the second gear (525) rotates. Screw threads are formed on the outer surface of the second rotating shaft (521).

[0093] The catch member (527) is screw-connected to the second rotary shaft (521) by being fitted therein. As illustrated in FIG. 2, when the unit support frame (210) and the auxiliary support member (310) are perpendicular to each other, the catch member (527) can be positioned at the center of the second rotary shaft (521). When the auxiliary support member (310) of the angle adjustment member (300) is rotated by the power of the power unit (400), the catch member (527) can move along the longitudinal direction of the second rotary shaft (521). That is, as the driving member (410) rotates, the first gear (425) of the power transmission member (420) rotates, and accordingly, the second gear (525) meshed with the first gear (425) rotates, so that the engaging member (527) moves along the longitudinal direction of the second rotary shaft (521) through rotation while being screw-coupled to the second rotary shaft (521). At this time, the first bevel gear (423) fitted to the first rotary shaft (421) also rotates, thereby rotating the second bevel gear (323), and as the second bevel gear (323) rotates, the actuator unit (320) moves linearly, thereby rotating the auxiliary support unit (310) coupled to the main frame.

[0094] In this way, when the locking member (527) moves along the longitudinal direction of the second rotating shaft (521), after moving a predetermined distance, it may be caught on a pair of stoppers (529) formed adjacent to the second rotating shaft (521) and its movement may be restricted.

[0095] A pair of stoppers (529) may have a size that allows the engaging member (527) to engage and restrict movement. The pair of stoppers (529) may be formed adjacent to the second rotary shaft (521), but may be formed to be spaced apart from each other by a predetermined distance. The engaging member may move along the second rotary shaft (521) until it engages one of the pair of stoppers (529), and when it engages one of the pair of stoppers (529), the rotation of the second rotary shaft (521) and the second gear (525) coupled with the stopper (529) may be stopped.

[0096] When the second gear (525) and the second rotating shaft (521) stop rotating, the first gear (425) meshed with the second gear (525) stops rotating, and the first rotating shaft (421) coupled with the first gear (425) and the first bevel gear (423) fitted onto the first rotating shaft (421) also stop rotating.

[0097] Accordingly, the second bevel gear (323) of the actuator part (320) engaged with the first bevel gear (423) stops rotating, and the linear movement of the actuator part (320) also stops, thereby stopping the rotation of the angle adjustment part.

[0098] For example, when a pair of stoppers (529) are separated by a first distance, if the catch member (527) catches on the first stopper (529a) of the pair of stoppers (529), the auxiliary support member (310) may stop rotating while being perpendicular to the unit support frame (210) and rotated 60 degrees upward, and if it catches on the second stopper (529b), the auxiliary support member (310) may stop rotating while being perpendicular to the unit support frame (210) and rotated 60 degrees downward.

[0099] The user can adjust the distance between a pair of stoppers (529) so that the angle adjustment part rotates to a desired angle. When the catch member (527) is caught by one of the pair of stoppers (529), the actuator part (320) stops moving in a straight line and the auxiliary support part (310) stops rotating, so the angle of rotation of the angle adjustment part can be controlled by adjusting the distance between the pair of stoppers (529).

[0101] FIGS. 8 to 10 are side views illustrating a method of driving a photovoltaic module system according to an embodiment of the present invention.

[0102] Referring to FIG. 8 and FIG. 10, the driving method of the angle adjustment unit (300) is explained. Looking at FIG. 8, the main frame unit (100) on which the solar panel is placed is formed horizontally. An arrangement state like that of FIG. 8 can be formed mainly during the daytime when the sun is highest in the sky.

[0103] Looking at FIG. 9, it can be seen that the rod (322) of the actuator unit (320) enters the body (321) through the provision of power from the power unit (400) or the position change force through the power connection unit (600), and the auxiliary support unit (310) rotates clockwise. In this case, the locking member (527) is caught on the first stopper (529a), causing the second rotation shaft (521) to stop rotating, and consequently, the first rotation shaft (421) also stops rotating, thereby causing the auxiliary support unit (310) to stop rotating and maintain a predetermined angle relative to the actuator unit (320). Since a plurality of angle adjustment units (300) are connected through the power connection unit (600) and power is transmitted, each of the auxiliary support units (310) of the plurality of angle adjustment units can achieve the same predetermined angle relative to the actuator unit (320). That is, the remaining angle adjustment units (300) can also rotate by the set angle by receiving power from the power unit (400) located at one end of the solar module system (1) in the longitudinal direction through the power connection unit (600).

[0104] Additionally, looking at FIG. 10, through the provision of power from the power unit (400) or the position change force through the power connection unit (600), the rod (322) of the actuator unit (320) moves in a straight line out of the body (321), and the structural frame unit (200) rotates counterclockwise. In this case, the locking member (527) is caught on the second stopper (529b), causing the second rotation shaft (521) to stop rotating, and consequently, the first rotation shaft (421) also stops rotating, thereby allowing the auxiliary support unit (310) to stop rotating and maintain a predetermined angle relative to the actuator unit (320). Since a plurality of angle adjustment units (300) are connected through the power connection unit (600) and power is transmitted, each auxiliary support unit (310) of the plurality of angle adjustment units can form the same predetermined angle with respect to the actuator unit (320).

[0105] In this way, it can be seen that the main frame part (100) is rotated by creating linear motion of the actuator part (320) through the power of the power part (400) or the power connection part (600). Therefore, in the solar power generation module system (1) of the present invention, the power part (400) can be installed only at the angle adjustment part (300) located at one end of the solar module system (1) in the longitudinal direction, thereby reducing costs and having the effect of controlling the main frame part (100) uniformly throughout through each angle adjustment part (300).

It will be apparent that modifications or improvements can be made by those skilled in the art within the technical scope of the invention.
