Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the constituent elements of the drawings, it is to be noted that the same constituent elements are denoted by the same reference numerals even if they are shown in different drawings. In the following description of the present invention, a detailed description of known configurations and functions will be omitted when it is determined that the gist of the present invention may be obscured.

First, referring to Figures 2 to 8, the technical solution of the solar power system seismic isolation device having a seismic isolation function according to an embodiment of the present invention, the base structure 100, seismic housing 200, seismic isolation The device 300 is composed of a pipe 400 for supporting a photovoltaic power generation system.

Referring to FIGS. 2 and 3, the foundation structure 100 is a means for distributing the vibrational seismic force installed on the roof top of the building 500, and has a constant diameter on the roof top of the building 500 and has a square bottom hole. After drilling (110a ~ 110d), the circular pipe (120a ~ 120d) is inserted into the bottom hole is poured into concrete. And it is possible to mount the seismic device housing by the hexagonal bolt penetrating into the circular pipe.

Here, the reason for installing the four circular pipes 120a to 120d is explained by the relationship between the earthquake and the structure. When there is a large shaking on the ground due to the earthquake, all objects placed on the ground are subjected to a force. However, because the object's frequency is close to the earthquake's frequency, the object receives a great force and collapses. In addition, the damage of the structure caused by the earthquake causes a great damage when the period of the earthquake and the period of the structure cause resonance, as well as the magnitude of the earthquake. This means that the vibration energy generated from the vibrating tuning fork is transferred to other tuning fork by using air as a medium, and the tuning fork of the same size and shape that can absorb the vibration energy of the air vibrates, but the tuning fork of different size and shape is used. Does not absorb vibrational energy, so resonance does not occur.

The phenomenon of easily exchanging vibrations occurs only when the intrinsic period between two objects is similar.

Therefore, in the embodiment of the present invention is to disperse the seismic force by varying the resonance phenomenon of the seismic force transmitted to the photovoltaic power generation system structure 600 through the building rooftop 500, and by extending the natural period.

In addition, the four circular pipes (120a ~ 120d) applied to the foundation structure 100 according to an embodiment of the present invention is similar to dispersing the seismic force through the pile head seismic method applied to the bridge construction, etc. The seismic force caused by the photovoltaic system is not burdened by the seismic system, and the cross section of four circular pipes is increased to resist rotation moment.

In addition, in the embodiment of the present invention by installing a shock absorber (Shock Absorber) between the base structure 100 and the building roof floor 500 can be absorbed and attenuated vibration seismic force. The shock absorbing device may prevent a phenomenon in which the pure rubber plate is buckled by embedding a metal plate inside the rubber pad for vibration damping.

The upper housing 210a having an open upper portion accommodating the solar power system support pipe 400 for supporting the solar power system structure 600 at the top of the cylinder and the seismic isolator 300 at the bottom of the cylinder. The lower housing 210b, which is open at the bottom for accommodating the respective parts, is welded.

In addition, the seismic device housing 200, the four sides of the circular structure (120a ~ 120d) of the base structure 100 is fixed to install the seismic device housing 200 on the outer circumferential surface of the cylinder 201 to vibrate horizontally The first coil-type seismic spring (250a ~ 250d) for the preparation of the seismic force has a built-in seismic device housing fixing bracket (230a ~ 230d), respectively.

Here, the seismic device housing fixing brackets 230a to 230d have hexagonal bolt holes through which the hexagonal bolts 240a to 240d penetrate.

On the other hand, the reason for installing four first coil-type seismic spring (250a ~ 250d) on the outer circumferential surface of the cylinder 201 is, in general, a rigid structure exhibits strong seismic characteristics against the seismic force that proceeds vertically It does not show strong seismic characteristics against the seismic force that proceeds horizontally and the structure can easily collapse.

Therefore, in the embodiment of the present invention, in order to prepare for the horizontal seismic force acting on the photovoltaic power generation system, four first coil-type seismic springs 250a to 250d are installed on the outer circumferential surface of the cylinder. In addition, it can be prepared for the seismic force vibrating horizontally through the second coil-type spring 310 described below. The first and second coil seismic springs are molded and manufactured to withstand the design load of the photovoltaic power generation system and enough seismic force over a predetermined scale.

4 to 7, the seismic isolator 300 is a seismic isolator for dispersing, absorbing, reducing and dissipating the seismic force transmitted to the photovoltaic power generation system structure 600 through the building roof top 500 or the ground. As a seismic means means having a function, it is embedded in the lower housing (210b) of the seismic housing (200). The seismic isolator is a first / second laminated rubber type seismic isolator (320,330) for dispersing and absorbing seismic force in order to prepare for the seismic force oscillating vertically and the second coil to reduce and dissipate the seismic force by lengthening the natural period of vibration The seismic isolation spring 310 and the seismic isolation insert 340 for separating the upper and lower seismic isolation inserts 343a to 343c and 370a to 370c in the event of an earthquake.

6 and 7, the seismic isolation device 300 according to an embodiment of the present invention has a seismic force that vertically progresses through a building roof top 500 or the ground when an earthquake occurs. It is a means of segregating and absorbing seismic force, dispersing and absorbing seismic force, and then reducing and dissipating it.Butadimen rubber (BR) and nitrile butadiene rubber (NBR) and urethane rubber (NBR) ) Has a first laminated rubber type isolating apparatus 320 is selected.

In addition, the second coil-type seismic spring 310 to eliminate the resonance phenomenon and to reduce and dissipate the seismic force by lengthening the natural period through the seismic spring against the seismic force dispersed and absorbed through the first laminated rubber type seismic isolator 320 This includes.

In addition, the upper and lower discs 341a which are seated on the upper and lower portions of the second coil seismic spring 310 to fix the coil seismic springs and make contact with the first and second laminated rubber type seismic isolation devices 320 and 330. , 341b) and one side of the upper and lower discs are fixed by a screw method, and are located inside the coil-type seismic spring to support the photovoltaic power generation system structure 600 in general, The upper and lower seismic isolation inserts 343a to 343c and 370a to 370c are separated and separated into two stages.

And it is mounted on the upper disk (341a) to the second coil-type seismic spring 310 to reduce the seismic force to be transmitted to the pipe 400 for supporting the photovoltaic power generation system so as to disperse and absorb the seismic power secondary A rubber (Butadimen Rubber) and NBR (Nitrile Butadiene Rubber), and the rubber is a second laminated rubber type isolator 330 is selected from any one of the urethane rubber (Urethane rubber).

Here, the synthetic rubber BR (Butadimen Rubber) refers to synthetic rubber polybutadiene rubber. BR rubber is a synthetic rubber produced and used next to raw rubber or SBR rubber. Generally, it is a stereo synthetic rubber. BR is a butadiene rubber and is characterized by excellent elasticity and low heat generation. BR synthetic rubber has two kinds of high sis bond and low cis bond. BR rubber is widely used in automobile tire production because of its excellent elasticity and dynamic properties. It is an elastic rubber that can withstand 100 km / h because of low heat generation, and has excellent durability and low temperature characteristics. BR rubber has two kinds of stereo type and Piene type, and it is excellent in abrasion resistance and white transparent synthetic rubber. That is, poly butadiene rubber (Rubber).

In addition, the synthetic rubber NBR (Nitrile Butadiene Rubber), the official name is called acrylonitrile butadiene (Acrylo Nitrile Butadiene). NBR is a rubber and binary copolymer used for oil resistance and heat resistance. Most rubber manufacturers use it in Korea. NBR synthetic rubber has low temperature polymerization and high temperature polymerization. 100% rubber contains 35-45% acrylonitrile and 55-65% butadiene rubber. Synthetic rubber NBR is a rubber raw material mainly used for oil-resistant objects, and the acrylonitrile component is a dendritic molecule, and the expansion degree of the oil substance varies depending on how much is contained in the rubber 100%. N31 series, NBR synthetic rubber standard, uses 20 types of hicars 1072 series, 30 types of N215 series, and many domestic uses N31 and N220 series and high cars 1002 series.

In addition, the urethane rubber is a rubber elastic body by reaction of polyester, polyethylene, and isocyanate. Urethane rubber is a highly elastic material and has the advantage of being superior to other synthetic rubbers.

As such, the upper and lower discs 341a and 341b for contacting the first and second laminated rubber type isolating devices 320 and 330 according to the embodiment of the present invention and the second coil type seismic spring 310 are provided. In addition to preventing the secondary phenomenon of pure rubber itself buckling, the object close to the frequency of the earthquake is subjected to a great force to prevent the collapse action. In other words, the damage of the structure caused by the earthquake is not only the size of the earthquake, but also the damage caused by the period of the earthquake and the structure of the earthquake causes a great damage, so that the same resonance does not occur to prevent this.

6 and 7, the seismic isolation insert 340 according to the embodiment of the present invention supports and protects the photovoltaic power generation system in the absence of an earthquake and protects the building roof 500 or the ground. When the earthquake occurs more than a certain magnitude through the seismic force seismic isolation insert 340 is divided into two stages by means of seismic force, the same shape and structure on the upper and lower disks 341a, 341b having a certain standard 120 ° angle The three furnaces are arranged in a triangle and one shape and structure thereof are as shown in FIG.

Here, the seismic isolation unit 348 according to the embodiment of the present invention has a kind of hourglass shape and a seismic force of a predetermined magnitude or more vibrating through the building roof top 500 or the ground is generated to pass through the earthquake isolation unit 348. When the insert rod groove 346 inserted into the insert rod groove 346 hits the relatively weak insert rod groove 346, the insert rod groove 346 ruptures and the insert rod groove 346 and the insert rod 347 are ruptured. ) Is separated into two stages, and the second coil-type seismic spring 310 supports and protects the photovoltaic power generation system and reduces the seismic force and extinguishes by extending the natural period of the earthquake by the spring's elastic force.

The configuration according to the embodiment of the present invention, when the second coil-type seismic spring 310 to support the protection of the photovoltaic power generation system having a heavy load even in the absence of earthquake, eventually the second coil The mold seismic spring 310 is to prevent the inherent elastic force of the spring is lost when the earthquake is contracted.

In addition, in the embodiment of the present invention by forming a first earthquake-resistant seismic spring (250a ~ 250d) formed on the outer circumferential surface of the earthquake resistance housing 200 built-in seismic device housing fixing bracket (230a ~ 230d), It is reinforced to provide sufficient support and protection of the photovoltaic power generation system while being prepared for vibrational seismic force.

It will be said that there is a unique feature that can sufficiently pursue the seismic force and seismic force while maintaining the unique function of the spring and fully supporting and protecting the photovoltaic system.
