The photovoltaic power generation system including the seismic device of the present invention includes a plurality of solar panels 3, a frame 30 supporting the solar panels 3, and the frame 30 as shown in FIGS. 2A and 2B. A pole (2) for stably installing and supporting the wall, a switchboard (10) for connecting the wires connected in series from the solar panels (3) in parallel, and electric power generated from the solar panels (3) to the load side It consists of an inverter (9), and a seismic device (5) is installed between the pillar (2) and the foundation or pillar (2) and the frame 30 structure.

The inverter 9 is applied to an independent solar power generation system or a grid-connected solar power generation system. An inverter applied to an independent solar power generation system supplies electricity generated by a battery or electricity stored in a battery. It means to perform the function to supply to the load side, the inverter applied to the grid-connected photovoltaic power generation system is a generic term that means a device that performs the function of converting and transmitting DC electricity to AC.

Such a seismic device is disposed between the upper or lower structure of the cradle of the solar panel 3 of the solar power plant as shown in Figure 2a, 2b, and combines the coupling means of the body 50 with the upper or lower structure, The fastening means is coupled to the structure connected to the opposite side of the coupling means to absorb the vibration energy of the transverse direction due to the earthquake through the buffer member.

In particular, the seismic device 5 of the present invention has a space 53 therein, as shown in FIGS. 3, 4A, and 4B, and a body having coupling means for coupling to a structure to be connected to the upper or lower portion thereof. (50), the buffer member 6 is elastically installed on the inner surface of the space of the body 50, and the body 50 is coupled to the one side connection target body while penetrating while compressing the buffer member (6) It consists of a fastening means for coupling to the connection object body, a support plate for mediating the buffer means of the fastening means, and a damper means for buffering between the body 50 and the connection object body.

Here, the concept of the upper structure and the lower structure is determined based on the seismic device (6) to be installed, as shown in the figure, when installed between the base (1) and the bottom of the column (2) the upper structure is a column (2) And the lower structure becomes the foundation (1). In addition, when installed between the upper end of the column 2 and the frame 30 is installed on the upper structure is the frame 30, the lower structure is the pillar (2).

In addition, the foundation (1) means that the various anchors 11, such as chemical anchors on the slab, such as the roof of the building or can support the concrete foundation (1) or photovoltaic power generation facilities to be installed in the ground. It also refers to the steel structure for which it is used.

Coupling means installed in the body 50, it can be understood as a second base plate 52 having a bolt hole formed around the body 50, which is the structure to be connected, that is by the upper or lower structure and bolted to Connected. In the case of the foundation 1, it is fastened to the anchor 11 with a nut.

The fastening means refers to a plurality of second anchor bolts 55 and nuts 56 fastened to the second anchor bolts 55, and the second anchor bolts 55 have an inner surface 54 in an inner space 53 of the body 50. The nut 56 is fastened to the shaft portion of the exposed second anchor bolt 55. The base plate 20 or the second base plate 52 of the upper structure or the lower structure may be directly coupled to the second anchor bolt 55, and the nut 56 may be connected to the nut 56. After adjusting the elasticity by using the tightening force of the second anchor bolt (55) can be seated on the upper or lower structure and fastened again by fastening the nut (56 '). At this time, as shown in Figure 5 may be assembled through the height compensation plate 72 higher than the height of the nut 56 is fastened first to adjust the elasticity. In this case, the height compensating plate 72 may be composed of an elastic member 73 such as a special rubber that is resistant to pressure to have a damper function. The height compensating plate 72 having a damper function may be simply formed by the elastic member 73 or may be configured by thinly stacking the lead 74 and the elastic member 73. [See FIG. The lead 74 and the elastic member 73 are laminated in such a way that the resilience of the elastic member 73 is restored when the vibration pressure is applied, and thus the lead 74 is laminated to restore the proper elastic force. The lead 74 is soft and deforms when subjected to pressure. When the vibration is applied when an earthquake occurs, the thickness of the lead 74 becomes thin, thereby delaying the restoring elasticity of the elastic member 73 together with the cushioning function.

In addition, the second anchor bolt 55 configured to compress the shock absorbing member 6 has its head directly supported by the shock absorbing member 6 to be cushioned by tightening the second anchor bolt 55 and the nut 56. Engage to compress the member 6. In this case, the shock absorbing member 6 may be configured as a coil spring, or may use a material such as a curved plate spring or a synthetic resin or rubber plate having elasticity. In particular, the cushioning member 6 derives an appropriate value through structural calculations and experiments within a range that does not impair the stability of the structure as a whole, and tightens only by that value. This value should be applied to each structure.

Meanwhile, in the structure in which the second anchor bolt 55 compresses the shock absorbing member 6, the head of the second anchor bolt 55 may support the shock absorbing member 6, but as shown in FIG. 4B. A support plate 70 having a bolt hole formed between the head of the second anchor bolt 55 and the buffer member 6 is installed, and the support plate 70 is tightened by the tightening of the second anchor bolt 55. ) Can be configured to compress

In addition, a damper hole 84 is formed on one surface of the body 50 to which the elastic force of the shock absorbing member 6 is applied as a damper means, and the shock absorbing rod 80 is inserted into the shock absorbing member 6 by an earthquake. When the body to be inclined (compression column and base plate, etc.), which has been inclined while being compressed, returns to its original position, it supports the lower part to delay the return speed or exhibit a cushioning function.

The buffer rod 80 may be made of various materials, but may be formed of a material having elasticity, for example, rubber or synthetic rubber, resin, or a soft metal such as lead 74. In order to increase the frictional efficiency between the damper hole 84 and the buffer rod 80 of the body 50, an unevenness 82 may be formed around the buffer rod 80. In particular, the concave-convex 82 is preferably formed in a barbed shape so as to have a structure that does not retreat when the damper hole 84 is moved by an impact.

When the earthquake occurs and shakes the foundation 1, it shakes the seismic device 5 firmly coupled thereto. By this operation, the pillar 2 installed on the seismic device 5 is also shaken. The lower part of the pillar 2 is formed by the weight and inertia of the frame 30 and the solar panel 3 installed on the lower portion of the pillar 2. Only move. That is, if the earthquake-resistant device 5 moved to the left side together with the foundation 1 by an earthquake, the lower part of the pillar 2 coupled thereon moves to the left side, but the upper part is going to be left as it is to the right side. It will tilt.

By this operation, the support plate 70 is pulled while the second anchor bolt 55 on the left side is pulled as shown in FIG. 4A, and the shock absorbing member 6 in the pulled position is compressed. The vibration energy due to the earthquake is absorbed by the compression of the shock absorbing member 6, and the same phenomenon occurs in different directions when the vibration cycle of the earthquake is changed, so that the shock absorbing effect of absorbing the vibration energy due to the earthquake is exerted.

However, when the compressive force of the shock absorbing member 6 is solved, the fast restoring force is acted on by the elastic force of the shock absorbing member 6, which may act as a negative factor to the safety of the structure.

This negative factor is solved by the damper, that is, the height compensation plate 72 or the buffer rod (80).

In the case of the structure in which the height compensation plate 72 performs the damper function, when the structure is shaken by an earthquake and the pillar 2 is inclined, one side of the base plate 20 is opened with the body, and the height that has been compressed therebetween. The thickness of the compensating plate 72 becomes thick. When the base plate 20 is returned in this state, the height compensating plate 72 is compressed, and the height compensating plate 72 is compressed, thereby delaying the return speed of the base plate 20. In other words, the buffer function will be performed.

In addition, in the case of the structure in which the buffer rod 80 performs the damper function, when looking into the moment in the continuous shaking process caused by the earthquake, the pillar 2 is inclined from the foundation by the earthquake, at which time The two anchor bolts 55 pull up one side of the support plate 70, and the buffer plate 80 is forcibly moved toward the connection target body by the support plate 70. FIG. When a portion of the buffer rod 80 is released through the damper hole 84 by the frictional resistance with the damper hole 84, even if the support plate 70 is returned to its original position, it is not restored While the body to be connected is restoring, the end of the buffer rod 80 is pressed. [See FIG. 4B] Although the buffer rod 80 is partially retracted by the force, the buffer rod 80 is subjected to frictional resistance with the damper hole 84. By retracting only a portion of the buffer rod (80) Additional distorted end to delay the return speed of the consolidated body, or exerts a buffer function.

If the height compensation plate 72 is located at the end of the buffer rod 80, the end of the buffer rod 80 pushes the height compensation plate 72 while exiting the damping hole 84, that is, the connection target body, When the base plate 20 of the pillar 20 is elastically returned, the cushioning function of the height compensating plate 72 and the buffer rod 80 operates together to further increase the shock absorbing function to further improve the seismic function.

As the seismic design of the present invention is reflected in the present invention, even if a natural disaster such as an unexpected earthquake occurs in the future, the resulting damage is expected to be reduced to a minimum, and the demand is expected to increase rapidly.
