Herein, the structure in which a solar panel (or solar panel unit) is mounted on the exterior of a building is described as an example, but the structure is not limited thereto, and the solar panel fixing device according to the present invention can be any device that can be mounted on a building. It is specified in advance that it can be applied to.

Hereinafter, “facing direction” is defined to mean a direction in which people face each other and get closer, and “facing direction” is defined to mean a direction in which they face each other and move away. Sliding refers not only to a specific direction, but also to the opposite direction of a specific direction.

Hereinafter, a solar panel fixing device according to the present invention will be described with reference to FIGS. 1 to 9.

The solar panel fixing device according to the present invention is preferably mounted on the exterior surface of a building in order to provide sufficient sunlight to the solar panel. It can be installed not only on the roof of a building, but also on the exterior wall.

Figure 1 is a schematic perspective view of a solar panel fixing device according to an embodiment of the present invention, showing the solar panel in a first position, and Figure 2 shows the solar panel of Figure 1 in the second position. It is a perspective view schematically showing the moving state.

Referring to Figures 1 and 2, the solar panel fixing device includes a guide frame module 110, a trolley module 121, 122, and 123, and a middle frame module 130.

The guide frame module 110 will be described with reference to FIG. 6 . The guide frame module 110 includes a base frame 111, a rail portion 113, and a guide frame 114.

The base frame 111 refers to a plate shape facing the exterior of the building. As the base frame 111 is fixed to the outer surface of the building, the guide frame module 110 is stably fixed. At this time, the base frame 111 may be fixed to the purlin 20 through a separate fastening means. For convenience of assembly, the purlin 20 may be configured in the form of a square bar extending in the first direction.

The base frame 111 may be configured as a combination of a pair of facing square plates. A first space 1111 is formed between the square plates. The first space 1111 refers to a hollow space extending in the first direction. As it is formed hollow, external vibration can be cushioned. Meanwhile, second spaces (not shown) may be formed on both sides of the first space 1111. This second space also extends in the first direction, but is configured as a receiving groove that opens outward to allow insertion of a rainwater catch plate (not shown). A rainwater receiving plate formed with a thickness corresponding to the receiving groove may be inserted and fixed.

The guide frame 114 is spaced apart from the base frame 111 in a parallel position by a preset distance. A rail portion 113 is formed between the base frame 111 and the guide frame 114. The guide frame 114 and the rail portion 113 extend in the first direction.

The guide frame 114 is preferably provided with a flat guide surface in order to stably guide the movement of the middle frame module 130 combined with the solar panel 101. The guide frame 114 has a square cross-section. It may be formed as a hollow bar. At this time, the guide surface refers to a surface facing the second direction or a direction opposite to the second direction. Here, the guide surface refers to the first surface 114a, which will be described later.

The rail portion 113 extending in the first direction may have irregularities corresponding to the shape of the wheel means 1211 formed on its outer surface for stable movement of the wheel means 1211. That is, the outer surface of the wheel means 1211 and the rail portion 113 are each formed with male and female irregularities, so that the trolley module can be stably guided in the first direction or in a direction opposite to the first direction.

The rail portion 113 may be connected to the virtual center line (extending in the first direction) of the guide frame 114. That is, the rail portion 113 may be connected to the center line of the side of the guide frame 114 facing the base frame 111 and extend in the first direction. An accommodating space in which the trolley module moves can be formed between the guide frame 114 and the base frame 111 by the rail portion 113. The accommodation space may be configured in a recessed form, and a pair of trolley modules 121 and 123 may be provided to be symmetrical to each other with the rail portion 113 interposed therebetween.

Accordingly, two solar panels 101 can be provided with the guide frame 114 as a boundary, and they can each move and tilt independently. In other words, the rail portion 113 may be formed as a partition side wall, and the rail portion 113 may be divided into a first side and a second side through the partition side wall. Trolley modules 121 and 123 may be provided on each of the first and second sides. The first side and the second side refer to sides opposite to each other. Additionally, the rail portion 113 may extend in the first direction to connect the surfaces of the base frame 111 and the guide frame 114 facing the base frame 111.

Referring to Figures 1 and 2, a pair of trolley modules 121 and 122 may be provided on the same side of one rail portion 113. It is preferable that only one of the pair of trolley modules 121 and 122 is combined with the middle frame module 130. This is to prevent interference between the pair of trolley modules 121 and 122 when the solar panel 101 is tilted.

The trolley module can be divided into a first trolley module 121, a second trolley module 122, and a third trolley module 123. In the case of FIG. 1, the middle frame module 130 may not be coupled to the third trolley module 123.

In FIG. 2, contrary to FIG. 1, the second trolley module (omitted in FIG. 2) and the middle frame module 130 are combined, and the middle frame module 130 is combined with the first trolley module 121. It may not be in a state.

The first to third trolley modules 121, 122, and 123 are distinguished by their arranged positions, and are preferably formed of the same structure. The second trolley module 122 includes a wheel housing 1222, a bracket portion 1223, a first part 1223a, and a first rotation shaft 1224, which are components corresponding to the first trolley module 121 (Figure 8). In addition, the third trolley module 123 also includes a wheel means 1231 and a wheel housing 1232 (see FIG. 2), and includes a first rotation shaft 1234 and a second rotation shaft 1235 (see FIG. 5). ).

As shown in FIG. 2, the guide frame 114 extends further in the first direction than the middle frame module 130. That is, the guide frame 114 has a margin section, so that the trolley module can be moved to the tilting non-interference position of the solar panel 101. As shown in FIG. 8, a locking protrusion 113b may be formed to make the operator or user aware of the tilting non-interference position. The outside of the locking jaw 113b represents a tilting non-interference position.

The guide frame 114 may be formed to be longer than the middle frame module 130 by a preset reference length based on the extension length in the first direction. At this time, the solar panel 101 may be formed to correspond to the extended length of the middle frame module 130. The middle frame module 130 may be formed to have a length corresponding to the solar panel 101 and be configured to move as one piece.

The middle frame module 130 refers to a link means to which the end of the solar panel 101 is fixed on one side and a trolley module is coupled to the other side. The middle frame module 130 also extends in the first direction, and can be fixed by holding the side end of the solar panel 101 in a 'ㄷ' shape.

FIG. 3 is a schematic cross-sectional view of a solar panel fixing device according to an embodiment of the present invention, FIG. 4 is a cross-sectional view schematically showing a structure further provided with a rainwater treatment groove in FIG. 3, and FIG. 5 is a schematic cross-sectional view of a structure further provided with a rainwater treatment groove in FIG. 3. This is a cross-sectional view schematically showing a structure in which a pair of trolley modules are provided.

With further reference to FIGS. 3 to 5, the middle frame module 130 of the solar panel fixing device according to the present invention will be described, and the coupling relationship between the middle frame module 130 and the trolley module will be described. 3 to 5, the description will be made based on the first trolley module 121.

The middle frame module 130 includes a body 131, a solar panel receiving portion 132, and a fixed side wall 133.

The body 131 extends parallel to the guide frame 114 and may be configured in the form of a hollow bar for seismic isolation. A solar panel receiving portion 132 is formed on one side of the two opposing sides of the body 131, and a fixed side wall 133 extends on the other side. That is, it is a structure with the body 131 in the center and solar panel receiving portions 132 and fixed side walls 133 formed on both sides.

The solar panel receiving portion 132 forms a receiving space that is open toward the side opposite to the guide frame 114. The solar panel 101 may be held in the accommodation space. This means that the end side of the solar panel 101 is inserted. The solar panel 101 is moved as one piece while being coupled to the middle frame module 130.

The body 131 includes a guide surface 1311 facing the first surface 114a of the guide frame 114. It is preferable that the shape of the guide surface 1311 is configured to face the first surface 114a and maintain a fine gap such that friction does not occur.

The fixed side wall 133 is in a direction perpendicular to the guide surface 1311 and extends in a second direction opposite to the guide frame 114. Based on the second direction, the end side is a bracket portion 1213. It is configured to be inserted and fixed.

Meanwhile, referring to FIG. 4, a rainwater treatment groove 113a is provided on the rail portion 113 to drain rainwater. The rainwater treatment groove 113a may be formed in the shape of a hole extending in the first direction.

Referring again to FIG. 5, each of the guide frame 114 and the base frame 111 has a first direction on the side facing the trolley (including wheel means 1211 and wheel housing 1212, which will be described later). The extended guide slits 1101 and 1102 may be formed to face each other. This is to guide the driving of the trolley module 121 more stably through the guide slits 1101 and 1102 as well as the uneven structure of the rail portion 113. The second rotation shaft 1215 provided in the trolley module 121 may be formed to pass through a pair of guide slits 1101 and 1102 and be coupled to each other. Through this, the trolley module 121 can be prevented from being separated from the rail portion 113 as much as possible.

With reference to Figure 7, the trolley module of the solar panel fixing device according to the present invention will be described. In Figure 7, the first trolley module 121 is explained as an example.

The first trolley module 121 includes a trolley, a first rotation shaft 1214, and a bracket portion 1213. The trolley includes a wheel means 1211 and a wheel housing 1212, and is coupled to a second rotation shaft 1215 that rotates the wheel means 1211. The wheel means 1211 and the second rotation shaft 1215 are formed as a pair and can move more stably. This is because the larger the contact area with the rail portion 113, the more stable movement is possible.

The wheel housing 1212 is configured to cover most of the wheel means 1211 (formed to cover at least a portion of the wheel means 1211). That is, the wheel housing 1212 is preferably configured to cover the rest of the wheel means 1211 except for the side that rubs against the rail portion 113. The wheel housing 1212 includes a first surface formed on the side opposite to the rail portion 113, and the first rotation axis 1214 is formed to penetrate the first surface. That is, the first rotation axis 1214 extends in a direction perpendicular to the rail portion 113. Additionally, the first rotation axis 1214 may be coupled to the wheel housing 1212 and may be formed in a direction perpendicular to the guide surface 1311.

The bracket portion 1213 is formed in a predetermined bent structure, and can be divided into first to third portions 1213a, 1213b, and 1213c based on the bent portion, into which the above-mentioned fixed side wall 133 is fitted. An insertion space 1213d is provided.

The first part 1213a refers to a part formed to face the first surface and coupled to the first rotation axis 1214. That is, it means the part through which the first rotation axis 1214 passes.

The second part 1213b refers to a part extending from the end of the first part 1213a in a direction opposite to the guide frame 114. The second part 1213b is a part that faces and contacts the fixed side wall 133 of the middle frame module 130.

The third portion 1213c is bent toward the guide frame 114 from the end of the second portion 1213b to form a predetermined insertion space 1213d open toward the guide frame.

The middle frame module 130 and the trolley module are preferably made of a material having the necessary rigidity to stably support the solar panel 101.

The first rotation shaft 1214 coupled to the first portion 1213a is divided into first and second rotation directions according to its rotation direction.

Figure 8 shows a state in which the solar panel is coupled to the second trolley module 122 in the solar panel fixing device of the present invention, (a) shows a state rotated in the first rotation direction, and (b) shows a state in which the solar panel is coupled to the second trolley module 122. 2 This is a conceptual diagram schematically showing the state rotated in the rotation direction.

FIG. 8 shows a state in which the middle frame module 130 is not coupled to the first trolley module 121, but is coupled only to the second trolley module 122. When the first rotation axis 1224 of the second trolley module 122 rotates in the first rotation direction, the solar panel 101 is configured to rotate downward. Conversely, when the first rotation axis 1224 rotates in the second rotation direction, the solar panel 101 is configured to rotate upward. As shown in FIG. 8, the tilting reference height of the solar panel 101 may be different depending on which trolley module it is tilted with.

Figure 9 shows the solar panel fixing device of the present invention, (a) shows the state rotated in the first rotation direction based on the state in which the solar panel is coupled to the second trolley module, and (b) shows the first trolley module. This is a conceptual diagram schematically showing the state in which the solar panel is rotated in the first rotation direction based on the state in which the solar panel is coupled. This will be explained further with reference to FIG. 9 .

Even when combined with the first trolley module 121, the same tilting angle as that of the solar panel 101 shown in (b) of FIG. 8 can be formed, but the reference height at which it is tilted can be formed differently. In this way, the solar panel fixing device according to the present invention can freely adjust not only the tilting angle of the solar panel 101 but also its reference height, so that its shape can be optimally adjusted according to the irradiated sunlight. .

The present invention can also be applied to a solar panel fixing system in which a plurality of solar panels are fixed. In this case, the plurality of solar panels can be tilted independently. Depending on the type of building, the roof or slope structure may be different, and sunlight irradiating a specific solar panel may be blocked by neighboring solar panels that tilt independently. In addition to the tilting angle, neighboring solar panels may be blocked. In order to prevent solar radiation interference between optical panels, the reference height can also be understood as a structure that can be set differently.

Meanwhile, on both ends of the rail portion 113, first and second locking protrusions 113b and 113c are formed at positions spaced apart from the ends by a preset distance. Referring again to FIG. 9, a first locking protrusion 113b may be formed on the second trolley module 122 side, and a second locking protrusion 113c may be formed on the first trolley module 121 side. At this time, the section between the first and second locking steps 113b and 113c may be defined as a tilting interference section.

Figure 10 is a conceptual diagram schematically showing the solar panel fixing device according to an embodiment of the present invention, (a) is a conceptual diagram schematically showing the state in which the solar panel is moved to the first position, and (b) is a solar panel is moved to the second position. This is a conceptual diagram that schematically shows the state of moving to a location. That is, in FIG. 10, the solar panel 101 shows a process in which the trolley modules 121 and 122 combined with the middle frame module 130 move in a straight line in the first direction or in a direction opposite to the first direction.

As shown in FIG. 10, the solar panel fixing device according to the present invention may have different reference heights when the solar panel 101 is tilted in the first position and when the solar panel 101 is tilted in the second position.

The middle frame module 130 can be roughly divided into four states depending on which trolley module it is coupled with.

The 'first state' is a state in which the middle frame module 130 is coupled only to the first trolley module 121 and rotates in the first rotation direction. The 'second state' is a state in which the middle frame module 130 is coupled only to the first trolley module 121 and rotates in the second rotation direction. The 'third state' is a state in which the middle frame module 130 is coupled only to the second trolley module 122 and rotates in the first rotation direction. The 'fourth state' is a state in which the middle frame module 130 is coupled only to the second trolley module 122 and rotates in the second rotation direction. In this way, the middle frame module 130 can shift the position of the solar panel 101 from the first to the fourth state, and can also independently adjust the tilting angle of the solar panel 101.

In the present invention, the above embodiment is an example and the present invention is not limited thereto. Anything that has substantially the same structure and achieves the same effect as the technical idea described in the claims of the present invention is included in the technical scope of the present invention.
