Description

[0001] Structures for solar panel installation [

The present invention relates to a structure for mounting a solar panel on the ground, and more particularly, to a structure capable of minimizing the airflow required for installing a solar panel, The present invention relates to an installation structure for a solar panel.

Solar panels use solar energy to produce electricity in the form of plates in which a number of cells form one module. Such a solar panel is installed together with the structure on the roof or mountain slope of a building having excellent solar radiation conditions. That is, the structure for installing the solar panel is generally composed of a column that is set up at a predetermined height from the ground, and a support frame that is assembled horizontally with respect to the columns to fix the solar panel.

In order to improve the power generation efficiency, the angle of the sunlight incident on the solar panel is important. In other words, in the past, the amount of incident sunlight was set to be fixed to the highest azimuth and angle. However, when the incident time is short and deviated from the set angle, the input specification is remarkably small and the power generation efficiency has to be low. In recent years, there has been a plan to change the angle of the solar panel in real time so that it can be tracked along the sunlight.

For example, Korean Patent Registration No. 10-1106097 entitled " Photovoltaic Tracker, Photovoltaic Power Generation Device Having It and Photovoltaic Power Generation System Having It, " and Korean Patent No. 10-1264846 entitled "Photovoltaic Tracker & . The former has the advantage of being capable of simultaneously switching the angles of the plurality of vertically and horizontally arranged solar modules, but is inclined only in one direction, so there is a limit in switching to an angle suitable for incident sunlight. The latter is easy to switch to an angle suitable for sunlight by adding a rotation function to the left and right tilt structure of the electron. However, it is costly and technically difficult to switch a plurality of solar power generation panels at the same time as electrons.

In addition, Korean Unexamined Patent Publication No. 10-2011-0121686 entitled " Feed-Forward Controlled Solar Tracking System for Operational Control "and Korean Patent Registration No. 10-1207270" Solar Tracking System for Solar Power Generation " In the proposed literature, a solar cell panel is connected to a column of a predetermined height so that it can be rotated and tilted, and is converted into an angle suitable for sunlight by an actuator that linearly moves on the bottom surface of the solar cell panel. However, it is difficult to apply to a large-scale facility because the joint for flowing the solar panel panel is formed at only one place. In particular, as described above, since only tilt and rotation can be performed, there is a limit in switching to an angle suitable for sunlight.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a structure for installing a solar panel (SP) on the ground, and is an installation structure for a solar panel having a fixing part (10), a supporting part (20) and an operating part . The present invention is capable of minimizing the amount of air required to install a solar panel (SP) while allowing the solar panel (SP) to be freely switched to a posture corresponding to the incident angle of the sun, The main point is to have a function that can be maintained.

The supporting part 10 according to the present invention is a frame connected to be able to arrange a plurality of solar panels SP as shown in FIGS. 1 and 2. The supporting frame 10 includes a supporting frame 11, a holder 15, Outer and inner brackets 17 and 18, respectively. The support frame 11 is interconnected with a size corresponding to one or more solar panels SP and serves to integrally connect the mount 15 and the support 20. [ The supporting frame 11 is formed with a plurality of fastening holes for guiding the fastening base 15 and the supporting portion 20 with balls and nuts. Of course, when the holder 15 and the support 20 are welded, the fastening holes may be omitted.

The shelf 15 has a cross-shaped profile formed by a length of at least one solar panel SP. The shelf 15 has a width that accommodates the solar panel SP at the upper end of the support frame 11 Respectively. An outer bracket 17 and an inner bracket 18, which press and fix the solar panel SP, are mounted on the upper end of the mounting table 15 with balls and nuts.

3A, the shelf 15 is bent in a cross shape so as to have a slot 15a into which the solar panel SP can be inserted at both ends thereof, and the outer bracket 17 is attached to the outer side of the solar panel SP and the inner bracket 18 is bent into a T shape so as to simultaneously press a pair of inner solar panels SP as shown in FIG. 3C.

That is, it is not formed through separate processing or welding, but is formed integrally by bending a plate material, so that it is easy to manufacture and has excellent durability. The solar panel SP is horizontally inserted into the slot 15a of the mounting table 15 while the outer and inner brackets 17 and 18 are assembled to the upper end of the mount 15, Reassemble the brackets (17) and (18) to complete the installation. Therefore, the fastening and fastening can be doubled while minimizing the number of mounting with the custom-made brackets 17 and 18 as well as being quick and convenient to install by the slot 15a.

The supporting part 20 according to the present invention is a frame which is fastened to support the fixing part 10 from the ground as shown in Figs. 1 and 2, and comprises a moving base 21 and a fixing base 25 as shown in Fig. The cradle 21 is fastened to the lower center of the support frame 11 and the fastener 25 is fastened to the concrete laid on the ground. The fluidized bed 21 and the fixed bed 25 have an I-shaped cross section so as to stably support the supporting frame 11 from the ground and are connected to the operating portion 30 between the fluidized bed 21 and the fixed bed 25 They are spaced apart from each other.

At this time, the fluidized bed 21 and the fixed bed 25 are formed by selecting one of the wye type Y, the cross type (+), and the star type (*) which are branched from the center by three or more from the center depending on the size of the support frame 11 . That is, as the number of the solar panels SP is increased, the size of the fixing part 10 increases and the weight of the fixing part 10 increases. Therefore, it is preferable to configure the core dispersion type structure having sufficient rigidity while minimizing the material ratio of the flow base 21 and the fixed base 25. [ Of course, in addition to the structure in which the sections are connected in a radial manner, it may be constructed as a simple plate type in some cases.

In addition, it is preferable that the flow base 21 and the fixing base 25 further include a support 20a having a predetermined size at one end which is branched into several branches. The support base 20a extends the cradle 21 and the fixing base 25 having a relatively narrow width to induce smooth connection of the operation unit 30. [ The support frame 20a is formed with a plurality of fastening holes for guiding the fastening of the support frame 11 and the concrete.

1 and 2, the actuating part 30 includes a plurality of variable pillars 31 as shown in FIG. 4, which supports the cage 21 in a state spaced apart from the cage 25 by a predetermined height, And a joint 35. The variable column 31 is an actuator mounted between the flow base 21 and the fixed base 25 and is constituted by a cylinder mounted on the fixed base 25 and a rod mounted on the flow base 21. That is, when power is applied to the cylinder from the outside, the rod moves up and down from the cylinder to change the posture of the solar panel SP. The power applied here can be selectively used among oil, air or electricity. The joint 35 is mounted at one end of the cylinder of the variable post 31 and at one end of the rod, respectively, to induce the direction to be switched according to the operation. That is, the joint 35 is formed in a cross or ball shape to freely change the direction of the variable post 31.

5A, the actuating part 30 is provided with a pair of variable pillars 31 for each of the support bars 20a of the cradle 21 and the fixed block 25. The variable pillars 31 are supported by the supports 20a ) Are zigzagged at mutually offset positions. Therefore, it is possible to raise, lower, tilt and rotate the solar panel (SP).

Conventionally, only the single adjustable column 31 is mounted at the corresponding position for each support 20a, so that the solar panel SP can be rotated or tilted only. Therefore, there is a limitation in coping with the angle of incidence suitable for the sunlight due to the limited attitude conversion of the solar panel (SP), and there is a problem that it is affected by the terrain and the ground. However, it is possible to freely switch the posture of the photovoltaic panel (SP), so that optimum power generation efficiency can be maintained at all times regardless of the terrain and the ground.

Hereinafter, an operation process of the attitude of the solar panel SP according to the operation of the structure according to the embodiment of the present invention will be described. Here, in order to facilitate understanding of the invention, the fixing part 10 and the solar panel SP mounted on the upper end of the float 21 are omitted. The fluidized bed (21) and the fixed bed (25) are formed as a wye (Y), and are connected to a total of six hydraulic type variable pillars (31).

First, when the height of the solar panel SP is to be switched, the same hydraulic pressure is simultaneously supplied to or discharged from all the variable columns 31. That is, as shown in FIG. 6, the fluidized bed 21 is moved up and down according to the hydraulic pressure while maintaining a horizontal state with the fixed bed 25. [ When the position of the solar panel SP is to be switched, the hydraulic pressure is supplied only to the variable column 31 corresponding to the moving direction, and the remaining variable columns 31 discharge or stop the hydraulic pressure. In other words, as shown in FIG. 7, the crawler base 21 is moved in all directions while maintaining a horizontal state with the cradle 25.

When the tilt of the solar panel SP is to be switched, the variable column 31 corresponding to the tilt axis maintains the stationary state and supplies and discharges the hydraulic pressure only to the variable column 31 corresponding to the tilt direction. In other words, as shown in FIG. 8, the cantilever 21 is inclined at a predetermined angle from the fixing table 25. Finally, when the solar panel SP is to be rotated, the hydraulic pressure of the adjoining variable pillars 31 is simultaneously supplied and discharged. In other words, the fluidized bed 21 is rotated while maintaining a horizontal state with the fixed bed 25.

Although the attitude change of the solar panel SP has been described separately for the sake of explanation, it is possible to realize the elevation, the position movement, the tilt and the rotation at the same time. Therefore, it is possible to freely switch to the attitude suitable for the incidence angle of the sunlight, so that the optimal power generation efficiency can be maintained at all times without regard to the terrain and the object. In particular, the present invention can be applied regardless of the size of the solar panel SP installed by replacing the column supporting the solar panel SP from the ground with the variable column 31 whose height is adjusted.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
