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, the solar modules are rotated through a single rotation shaft. However, since the height and slope of the ground change, rotating multiple solar modules simultaneously through a single rotation shaft causes problems such as errors in the rotation angle of each solar module and deterioration in the durability of the solar device.

[0040]

[0041] Hereinafter, a solar module system (1) according to the present invention will be described with reference to the drawings.

[0042]

[0043] Figures 1 to 5 illustrate a solar module system (1) according to one embodiment of the present invention.

[0044]

[0045] A solar module system (1) according to one embodiment of the present invention comprises: a main frame part (100) that can rotate around a longitudinal axis; a structural frame part (200) that is installed on the main frame part (100) and on which a solar panel (P) is mounted and that rotates in conjunction with the main frame part (100); a support frame part (300) that is installed on the lower side of the main frame part (100) and supports the main frame part (100) from the ground; a plurality of angle adjustment parts (400) that are installed on the support frame part (300) and adjust the longitudinal central rotation angle of the main frame part (100); a power part (500) that is formed on the angle adjustment part (400) located at one end of the longitudinal direction and provides power to the angle adjustment part (400); and a power unit (500) that is formed between the angle adjustment parts (400) to transmit power of the power unit (500) between the angle adjustment parts (400). Includes a power transmission member (600).

[0046]

[0047] A solar module system (1) according to one embodiment of the present invention includes a main frame portion (100), a structural frame portion (200), a support frame portion (300), an angle adjustment portion (400), a power portion (500), and a power transmission member (600).

[0048] Referring to Fig. 1, the main frame portion (100) may be installed so as to extend in the longitudinal direction and be installed parallel to the ground, or may be formed so as to be spaced apart from the ground by a certain distance. A structural frame portion (200) is formed on the main frame portion (100). A solar panel (P) is mounted on the structural frame portion (200). The solar panel (P), the structural frame portion (200), and the main frame portion (100) are interlocked with each other and rotate together.

[0049] The support frame section (300) serves to support the main frame section (100) from the ground.

[0050] The angle adjustment part (400) is formed in the support frame part (300). The angle adjustment part (400) is formed to adjust the longitudinal center rotation angle of the main frame part (100).

[0051] The power unit (500) is formed in the angle adjustment unit (400) located at one end in the longitudinal direction and supplies power to the angle adjustment unit (400). Therefore, the power unit (500) is located at one end of the solar module system (1) so that the entire system (1) can be driven by generating power at one end in the longitudinal direction.

[0052] Looking at FIGS. 3 to 5, it can be seen that the solar panel (P) rotates by the driving of the angle adjustment unit (400) of the present invention. The specific configuration of the angle adjustment unit (400) will be described later.

[0053] The power transmission member (600) is a configuration formed between angle adjustment members (400) and serves to transmit the power of the power unit (500) in the longitudinal direction of the system (1). The position of the power transmission member (600) changes according to the movement of the angle adjustment member (400), and accordingly, the position of the angle adjustment member (400) continuously formed in the longitudinal direction can also be changed through the power transmission member (600).

[0054]

[0055]

[0056] In a solar module system (1) 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).

[0057]

[0058] Referring to FIG. 1, it can be seen that the main frame portion (100) of the 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).

[0059] A plurality of unit main frames (110) are configured to be connected to each other in the longitudinal direction. Since the main frame section (100) cannot respond to multiple slopes and changes in ground height with a single frame, it is formed with a plurality of unit main frames (110).

[0060] The first joint part (120) is a configuration that adjusts the angle between the unit main frames (110), and may be formed as a universal joint, but is not limited thereto.

[0061]

[0062] In a solar module system (1) according to one embodiment of the present invention, the support frame part (300) may include a plurality of unit support frames (310) 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 (320) coupled to the upper side of the unit support frame (310) to enable the unit main frame (110) to rotate about an axis.

[0063]

[0064] Referring to FIGS. 1 and 3 to 5, the support frame (300) of the solar module system (1) according to one embodiment of the present invention may include a unit support frame (310) and a rotation support member (320). The unit support frame (310) is configured as a single column that supports the solar module system (1) while keeping it apart from the ground. The rotation support member (320) is configured to surround the unit main frame (110) as illustrated in FIG. 1 and be coupled to the upper end of the unit support frame (310). The rotation support member (320) serves to support the unit main frame (110) so that it can rotate about its axis.

[0065]

[0066] In a solar module system (1) according to one embodiment of the present invention, the angle adjustment unit (400) may be installed on some or all of the plurality of unit support frames (310), and may be installed on the unit support frame (310) located at one end in the longitudinal direction.

[0067]

[0068] Referring to FIG. 1, it can be seen that the angle adjustment unit (400) is not installed in all of the unit support frames (310), but is installed in some of the unit support frames (310). That is, the angle adjustment unit (400) may be installed in some or all of the unit support frames (310) depending on the situation. At this time, the angle adjustment unit (400) must be installed at one end in the longitudinal direction where the power unit (500) is formed, and accordingly, the angle adjustment unit (400) is installed at the unit support frame (310) located at one end in the longitudinal direction.

[0069] The frequency at which the angle adjusting unit (400) is formed in the unit support frame (310) may be formed as 1 to 5 per 10 unit support frames (310). When the frequency of installing the angle adjusting unit (400) is 5 per 10 unit support frames (310), the angle adjusting unit (400) may be installed by skipping each unit support frame (310), and in the case of a design in which many angle adjusting units (400) 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 (400) may be formed as 1 per 10 unit support frames (310).

[0070]

[0071] In a solar module system (1) according to one embodiment of the present invention, the angle adjustment unit (400) may include an auxiliary support unit (410) that is fixedly connected to the unit main frame (310) and the rotation support unit (320) and is linked to the movement of the unit main frame (110), and an actuator unit (420) that is connected to the auxiliary support unit (410) and the unit support frame (310) and moves the auxiliary support unit (410) by a linear motion to rotate the unit main frame (110).

[0072]

[0073] The angle adjustment unit (400) of the solar module system (1) according to one embodiment of the present invention may include an auxiliary support unit (410), an actuator unit (420), and a sub-frame (430).

[0074] Referring to Fig. 1, the auxiliary support member (410) is fixedly connected to the unit main frame (310) and the rotation support member (320). The auxiliary support member (410) is configured to move in conjunction with the unit main frame (310). Therefore, the unit main frame (310) rotates due to the movement of the auxiliary support member (410).

[0075] The actuator unit (420) is coupled to the unit support frame (310) to move the auxiliary support unit (410) by linear motion. The actuator unit (420) may be composed of a body (421) and a rod (422), and the auxiliary support unit (410) may be moved by linear motion of the rod (422) to rotate the unit main frame (110). The energy for linear motion of the actuator unit (420) may be transmitted through the power unit (500) or the power transmission member (600). The connection between the two may be hinge-coupled so that the auxiliary support unit (410) is moved by the movement of the actuator unit (420).

[0076] The sub-frame (430) can be formed by extending vertically from the unit support frame (310) and can be hinge-connected to the actuator unit (420).

[0077] The driving method of the angle adjustment unit (400) is explained. Referring to Fig. 3, the structural frame unit (200) on which the solar panel (P) is mounted is formed horizontally. An arrangement such as Fig. 3 can be formed mainly during the day when the sun is at its highest. Referring to Fig. 4, it can be seen that the rod (422) of the actuator unit (420) enters the body (421) and the structural frame unit (200) rotates clockwise through the provision of force from the power unit (500) or the position change force through the power transmission member (600). In addition, referring to Fig. 5, it can be seen that the rod (422) of the actuator unit (420) moves linearly in the direction of coming out of the body (421) through the provision of force from the power unit (500) or the position change force through the power transmission member (600), thereby causing the structural frame unit (200) to rotate counterclockwise. In this way, it can be seen that the linear movement of the actuator part (420) is created through the power of the power unit (500) or the power transmission member (600) to rotate the structural frame part (200).

[0078]

[0079] In a solar module system (1) according to one embodiment of the present invention, the power transmission member (600) may include a plurality of pipes (610) connecting the actuator part (420) of the angle adjustment part (400) and the hinge part to which the auxiliary support part (410) is coupled, and a second joint part (620) formed between the pipes (610) to adjust the angle between the pipes (610).

[0080]

[0081] The power transmission member (600) of the solar module system (1) according to one embodiment of the present invention may include a plurality of pipes (610) and a second joint portion (620).

[0082] A plurality of pipes (610) are configured to connect the hinge portion where the actuator portion (420) and the auxiliary support portion (410) are combined, and the energy of the hinge portion of the actuator portion (420) moving due to the movement of the pipes (610) is transferred to the actuator portion (420) of the adjacent angle adjustment portion (400), thereby allowing the plurality of angle adjustment portions (410) to operate in conjunction with each other.

[0083] The second joint portion (620) is configured to connect a plurality of pipes (610). A universal joint may be used, but is not limited thereto. The second joint portion (620) adjusts the angle between the pipes (610), thereby enabling the main frame portion (100) to be designed to bend along the ground.

[0084]

[0085] In a solar module system (1) according to one embodiment of the present invention, a first gear part (130) for adjusting the angle of the first joint part (120) may be further included.

[0086] In a solar module system (1) according to one embodiment of the present invention, a first sensor unit (140) for measuring the angle of the first joint unit (120) may be further included.

[0087] In a solar module system (1) according to one embodiment of the present invention, a control unit (700) may be further included to correct the difference between the preset reference angle of the first joint part (120) according to the preset rotation angle of the unit main frame (110) and the angle of the first joint part (120) measured by the first sensor part (140) through the first gear part (130).

[0088]

[0089] A solar module system (1) according to one embodiment of the present invention may include a first gear unit (130), a first sensor unit (140), and a control unit (700).

[0090] The first gear portion (130) is configured to adjust the angle of the first joint portion (120) and may be formed as a gearbox. Referring to FIG. 2, the first gear portion (130) may be connected and coupled to the first joint portion (120), and accordingly, the angle of the first joint portion (120) may be adjusted by the operation of the first gear portion (130).

[0091] The first sensor unit (140) is composed of a sensor that measures the angle of the first joint unit (120).

[0092] Referring to Fig. 6, a configuration diagram of a solar module system (1) according to an embodiment of the present invention can be seen, and the relationship between the control unit (700) according to an embodiment of the present invention and other configurations can be seen. The control unit (700) compares the angle of the first joint unit (120) measured by the first sensor unit (140) with the preset angle of the first joint unit (120) according to the preset rotation angle of the unit main frame (110), and if a difference occurs, operates the first gear unit (130) to correct the difference.

[0093] Figure 7 is an operation flow chart of a solar module system (1) according to one embodiment of the present invention.

[0094] Step S701 is that the control unit (700) operates the power unit (500) to drive the angle adjustment unit (400).

[0095] In step S702, the control unit (700) measures the angle of the first joint unit (120) through the first sensor unit (140).

[0096] In step S703, the reference angle of the first joint part (120) is calculated according to the rotation angle of the unit main frame (110). The first joint part (120) may be formed as a universal joint, and due to the characteristics of the universal joint, the entire main frame part (100) rotates at the same rotation angle. However, due to the stress generated in the universal joint and the possibility of a change in the angle of the joint, the previously set reference angle of the first joint part (120) may change as the main frame part (100) rotates. If the reference angle of the first joint part (120) that was previously set according to the rotation angle of the unit main frame (110) changes, the amount of light incident on the solar panel (P) may change, and thus a task to correct this becomes necessary.

[0097] Step S704 compares the reference angle of the first joint part (120) set according to the rotation angle of the unit main frame (110) with the angle measurement value obtained through the first sensor part (140). If the reference angle of the first joint part (120) and the angle measurement value obtained through the first sensor part (140) are the same, the step is terminated. If the reference angle of the first joint part (120) and the angle measurement value obtained through the first sensor part (140) are different, step S705 is performed.

[0098] Step S705 adjusts the reference angle of the first joint part (120) through the first gear part (130) illustrated in FIG. 2 to be the same as the angle measurement value obtained through the first sensor part (140). Thereafter, the process returns to step S702 and the above operation is performed again.

[0099]

[0100] In a solar module system (1) according to one embodiment of the present invention, a second gear part (630) for adjusting the angle of the second joint part (620) may be further included.

[0101] In a solar module system (1) according to one embodiment of the present invention, a second sensor unit (640) that measures the amount of stress change in the second joint unit (620) may be further included.

[0102] In a solar module system (1) according to one embodiment of the present invention, the control unit (700) can change the angle of the second joint unit (620) through the second gear unit (630) when the amount of stress change measured by the second sensor unit (640) is greater than a reference value.

[0103]

[0104] A solar module system (1) according to one embodiment of the present invention may include a second gear unit (630), a second sensor unit (640), and a control unit (700).

[0105] The second gear portion (630) is configured to adjust the angle of the second joint portion (620) and can be formed as a gearbox. It can be viewed as having the same concept as the first gear portion (120) of Fig. 2.

[0106] The second sensor unit (640) is a sensor attached to the second joint unit (620) and measures the amount of stress change in the second joint unit (620). The second sensor unit (640) may be formed as a STRAIN GAGE ​​sensor.

[0107] Referring to FIG. 6, a configuration diagram of a solar module system (1) according to an embodiment of the present invention can be seen, and the relationship between the control unit (700) according to an embodiment of the present invention and other configurations can be seen. The control unit (700) measures the amount of stress change of the second joint unit (640) measured by the second sensor unit (640), and when the amount of stress change exceeding a reference value is measured, changes the angle of the second joint unit (640) through the second gear unit (630). As can be seen from FIG. 1, while the main frame unit (100) performs the rotation and load support functions of the solar panel (P), the power transmission member (600) does not support the load, but is formed as a member that transmits power by changing its position in response to the movement of the actuator unit (420). Accordingly, it is configured with a thin pipe (610) compared to the main frame unit (100), and is configured to focus on transmitting power. Therefore, a thin thickness means that it is vulnerable to stress, and in addition, when the power transmission member (600) that is bent by the second joint part (620) moves or rotates, the stress applied to the second joint part (640) cannot but increase. Therefore, the second sensor part (640) measures the amount of stress change in the second joint part (640) so that fatigue failure of the second joint part (640) can be prevented.

[0108] Figure 8 is a flowchart of a solar module system (1) according to one embodiment of the present invention.

[0109] Step S801 is that the control unit (700) operates the power unit (500) to drive the angle adjustment unit (400).

[0110] In step S802, the control unit (700) measures the amount of stress change in the second joint unit (620) through the second sensor unit (640).

[0111] In step S803, the control unit (700) compares the reference value, which is the limit value of the stress change amount that the second joint part (620) can withstand, with the stress change amount measured by the second sensor part (640), and if the reference value is smaller than the measured stress change amount, the step is terminated. The stress change amount measured by the second sensor part (640) is compared, and if the reference value is larger than the measured stress change amount, the step S804 is entered. The graph measured through the second sensor part (640) up to that step is illustrated in FIG. 9. Looking at the left graph fluctuation of FIG. 9, it can be seen that the step is terminated in step S802 when the measured stress change amount (△S) does not exceed the reference stress change amount (dotted line). Looking at the middle graph fluctuation of FIG. 9, it can be seen that the step S804 is performed when the measured stress change amount (△S) exceeds the reference stress change amount (dotted line).

[0112] In step S804, the second gear unit (630) is driven. By driving the second gear unit (630), the angle of the second joint unit (620) is changed, so that the second joint unit (620) is subjected to less stress.

[0113] In step S805, the second gear unit (630) is driven until the real-time stress change measurement value measured by the second sensor unit (640) falls below the reference stress change amount (dotted line). At this time, when the control unit (700) measures the real-time stress change amount by a certain percentage lower than the reference stress change amount (dotted line), the step can be terminated by stopping the operation of the second gear unit (630). Referring to Fig. 9, it can be seen that the step is terminated when the real-time stress change measurement value falls below a certain percentage lower than the reference stress change amount. Here, the certain percentage can be formed as 60% or more and 80% or less compared to the reference stress change amount. If the above-mentioned constant ratio is formed to be less than 60% of the standard stress change amount, the angle of the second joint part (620) that the second gear part (630) must change becomes excessively large, and the angular difference between the power transmission member (600) and the main frame part (100) becomes excessively large, which may cause a problem in the power transmission function. In addition, if the above-mentioned constant ratio exceeds 80% of the standard stress change amount, the stress reduction of the second joint part (620) may be insignificant in reality, and when the power unit (500) is restarted in the future, the stress change amount in the second joint part (620) may be formed to be excessively high, which may cause a problem that the operation of the power unit (500) must be stopped to prevent fatigue destruction of the second joint part (620).
