The present invention is focused on easily collecting solar light and solar heat, transferring the solar light to various uses, and utilizing it for various purposes, regardless of whether the sunlight flows in either direction from north to south.

For this purpose, a spherical condensing body 100 having different types of condensing lenses 110 is provided so that the sunlight can be easily condensed regardless of the direction of the sunlight.

The spherical collector 100 has a spherical shape, and one surface of the entire outer surface is divided into an eastward surface, the other surface is divided into a surface facing the west, and a long central portion in the north-south direction extends in any direction And condensing lenses 110 of different shapes are formed on the respective partition surfaces.

The condenser lens 110 includes a first Fresnel lens unit 111 extending in the north-south direction around the center of the upper end of the spherical condenser 100 and a second Fresnel lens unit 111 formed on one surface of the spherical condenser 100 facing the east A third Fresnel lens portion 113 formed on the other surface facing the west of the spherical light collector 100 and a fourth Fresnel lens portion 113 formed on the lower end of the spherical light collector 100, And a Fresnel lens unit 114. [

More specifically, the first Fresnel lens unit 111 has a concentric arrangement centering on the upper center of the spherical condenser 100 and a contour arrangement extending in the north-south direction, The third Fresnel lens part 113 is formed in a shape of a rectangle extending in a radial direction around an upper end of one side surface facing the east of the spherical light collector 100, And extends in the radial direction around the upper end on the other surface facing the west of the housing 100 and has an equally spaced contour line arrangement.

The fourth Fresnel lens unit 114 is formed in a concentric arrangement from the bottom center of the spherical condenser 100 to the bottom half of the sphere.

The reason for forming the first Fresnel lens portion 111 having a concentric arrangement centering on the upper center of the spherical condenser 100 and forming a contour arrangement in the east-west direction among the structures of the condenser lens 110 is as follows. This is because the first Fresnel lens portion 111 can easily condense sunlight in any direction.

The reason why the second Fresnel lens portion 112 is formed on one surface of the spherical condenser 100 facing the east is that the sunlight can be concentrated intensively when the sunlight passes east, The reason why the third Fresnel lens portion 113 is formed on the other surface facing the west side of the light collecting body 100 is that the solar radiation angle in the winter season is taken into consideration and the solar light incident indirectly from the west can be easily condensed .

The reason why the fourth Fresnel lens portion 114 having a concentric circular structure is formed at the lower end of the spherical light collector 100 is that the sunlight condensed through the first to third Fresnel lens portions 111, So that it can be collected toward the transparent tank 120.

The spherical condenser 100 thus mounted is mounted on a hollow transparent tank 120 using a fixing member such as a usual sealing material and a bracket and solar heat of high temperature due to sunlight exists therein, External air flow holes 116 and 118 are formed at one side and the other side of the spherical collector 100 as shown in FIG. 1E to exclude the risk of explosion.

At this time, the first and second transparent plates 130 and 132 are integrally sealed and attached to the upper and bottom surfaces of the hollow transparent tank 120, and the first and second transparent plates (not shown) including the transparent tank 120 130,132) can be made of transparent glass or transparent plastic.

The hollow transparent tank 120 is provided with an inverted conical reflector 140 for reflecting sunlight condensed by the spherical condenser 100 toward the second transparent plate 130.

That is, the inverted conical reflector 140 is provided in a hollow inverted conical shape that can be gradually narrowed downward from the top to the bottom of the inverted conical reflector 140, And the upper end of the first transparent plate 130 is spaced below the first transparent plate 130 located at the bottom of the spherical light collector 100.

The inner surface of the inverted cone-shaped reflector 140 is formed by a mirror for reflecting light, and the light reflected from the mirror for mirroring is irradiated on the upper end of the inverted cone- The curved light shielding film 142 is integrally formed to have a predetermined curvature in the inward direction.

On the other hand, by supplying water into the transparent tank 120 in which the inverted conical reflector 140 is installed and heating it by the condensed solar heat, hot water can be continuously used, or air can be supplied, So that it can be used for indoor heating in winter.

Of course, as the sunlight is condensed and reflected, the inside of the inverted conical reflector 140 and the transparent tank 120 can be heated, so that the water or the outside air supplied as described above is supplied to the inverted conical reflector 140 and the transparent tank 120 The inner temperature of the inverted conical reflector 140 and the transparent tank 120 can be adjusted to an appropriate level.

An inlet 124 is formed at the lower end of the inverted conical reflector 140 to receive a water supply or air supply hose 122 extending from the lower end of the transparent tank 120, The hose 122 is connected to an outlet 128 through which the water or air is supplied through the inlet 124 to which the water supply or air supply hose 122 is connected. The water or air is heated by the solar heat collected by the spherical condenser 100 and reflected by the solar heat transferred to the hollow transparent tank 120 and the inverted cone reflector 140, have.

At the same time, the water or the outside air exchanges heat with solar heat inside the inverted cone reflector 140 and the transparent tank 120, and the internal temperature of the inverted cone reflector 140 and the transparent tank 120 is adjusted to an appropriate level.

A flat plate type Fresnel lens 150 which reflects the sunlight passing through the second transparent plate 132 to one place after being reflected by the inverted conical reflector 140 is spaced apart from the bottom of the transparent plate 130 .

In particular, a rectangular prism 160 capable of separating sunlight from the planar Fresnel lens 150 into visible light, ultraviolet light, and infrared light is disposed at the bottom of the flat Fresnel lens 150.

The rectangular prisms 160 are assembled in a rectangular shape while closely contacting the upper vertexes of the triangular prisms 161, 162, 163 and 164 so as to separate sunlight into visible rays, ultraviolet rays and infrared rays. The rectangular prisms 160 are arranged on the bottom surfaces of the triangular prisms 161, 162, This becomes the upper, lower, left, and right sides of the square body.

That is, the upper surface of each of the triangular prisms 161, 162, 163, and 164, that is, the upper, lower, left, and right surfaces of the rectangular prism 160 becomes a light inflow surface 165 that coincides with the flat Fresnel lens 150, The bottom surface opposite to the light source 165 is the visible light separation surface 167 and the left and right surfaces are the ultraviolet separation surface 168 and the infrared separation surface 166, respectively.

According to the present invention, the infrared prism 160 includes a power generating and shading unit 170 capable of producing electrical energy using infrared rays from the rectangular prism 160. The infrared prism 160 includes an infrared dividing surface 166, A heat exchanger 172 for heating and heating the cooling water by the infrared rays transmitted from the quartz glass rod 171 and a heat exchanger 172 for radiating heat from the heat exchanger 172, A conventional generator 174 for generating electric energy while rotating the turbine 173 using high pressure steam and a pump 176 for circulating the cooling water liquefied in the steam to the heat exchanger, A conventional battery 175 for storing electricity generated from the generator is connected.

On the other hand, a branched quartz glass rod 178 is extended to a predetermined position of the quartz glass rod 171 so that infrared heat is transmitted from the quartz glass rod 171 to the branched quartz glass rod 178, So that the infrared heat transmitted to the quartz glass rod 178 can be transmitted to a place (a plant tube, an aquarium, etc.) where the infrared heat is required.

Hereinafter, the operation of the multi-purpose solar concentrator according to the present invention will be described.

In the summer and winter season, the condensing lens 110 formed on the spherical condensing body 100 extends from the east side to the south side and extends to the east, including the first Fresnel lens portion 111 And is condensed directly through the formed second Fresnel lens portion 112.

Of course, the sunlight is indirectly condensed through the third Fresnel lens portion 113 formed on the surface facing the west of the spherical collector 100.

Accordingly, even if sunlight flows in any direction, sunlight can be easily condensed by the condenser lens 110 of the spherical condenser 100.

The irradiation direction of the sunlight condensed by the condenser lens 110, that is, the first to third Fresnel lens sections 11, 112, 113, and 114, is such that the spherical condenser 100 itself is formed in a spherical shape such as a concave lens The condensed light is focused toward the fourth Fresnel lens portion 114 formed at the lower end of the spherical condenser 100 and the sunlight condensed by the fourth Fresnel lens portion 114 is condensed in the inverted conical shape Facing the inside of the reflector 140.

Most of sunlight condensed by the fourth Fresnel lens unit 114 passes through the first transparent plate 130 and is intensively irradiated into the inverted conical reflector 140. Of course, a part of the sunlight is transmitted through the transparent tank 120 And the space between the inverted conical reflectors 140 is also irradiated.

Subsequently, the sunlight concentrated inside the inverted conical reflector 140 is sequentially reflected downward through a mirror surface formed on the inner surface of the inverted conical reflector 140, 2 transparent plate 132, as shown in FIG.

At the same time, the sunlight passing through the second transparent plate 132 passes through the plate-type Fresnel lens 150 and is collected into one focal point, and is transmitted to the rectangular prism 160.

Subsequently, when sunlight flows into the light inflow surface 165 that coincides with the flat plate-shaped Fresnel lens 150 of the square prism 160, the lower surface, which is opposite to the light inflow surface 165, ), And the seat surface and the right side become the ultraviolet ray separation surface 168 and the infrared ray separation surface 166, respectively.

Accordingly, when the sunlight enters the light inflow surface 165 of the rectangular prism 160, the sunlight is dispersed and seven colors of red, green, and blue are displayed. Among these, The infrared rays of wavelengths are separated through the infrared ray separation surface 166 on the right side of the rectangular prism 160 and the electromagnetic waves that are further outward than the purple color, that is, the ultraviolet rays whose wavelengths are shorter than the purple color, And the visible ray is positioned between the ultraviolet ray and the infrared ray so that the visible light ray is separated from the visible light ray separation surface (i.e., the visible light ray separation surface) opposite to the light inflow surface 165 of the rectangular prism 160 167).

At this time, the optical fiber or the light pipe is disposed on the visible light separation surface 167 so that the visible light emitted from the gas light separation surface 167 is emitted to a place where the room lighting is required (for example, ).

In addition, the optical fiber or the light tube is disposed on the ultraviolet ray separation surface 168 so that ultraviolet rays emitted from the ultraviolet ray separation surface 168 can be transmitted to a sterilization target site including a large tableware storage such as a sterilizer.

In particular, the infrared rays emitted from the infrared ray separation surface 166 of the rectangular prism 160 are transmitted to the electricity generating and storage unit 170 that generates electricity.

The quartz glass rod 171 disposed apart from the infrared ray separation surface 166 of the rectangular prism 160, that is, the quartz glass rod 171 having high infrared ray transmission efficiency, (Not shown) partitioned inside the heat exchanger 172 along the quartz glass rod 171 and then pumped from the pump 176 The process of heating the cooling water entering the heating space proceeds.

Subsequently, when steam is produced from the cooling water heated by the infrared rays, the high-pressure steam is discharged through the outlet of the heat exchanger 172 and the turbine 173 of the generator 174 is rotated, Electricity is generated from the battery 174, and the generated electricity can be sent to a place where electricity is required, and otherwise, it is charged into a normal battery 175.

When the infrared ray is transmitted to the quartz glass rod 171, the infrared rays are transmitted also to the branched quartz glass rod 178 branched from the quartz glass rod 171, It can be transferred to places where heat is needed (plant pipes, aquariums, etc.) and utilized.

The sunlight condensed by the condenser lens 110 of the spherical condenser 100 is concentrated inside the inverted conical reflector 140 and some sunlight is condensed between the transparent tank 120 and the inverted conical reflector 140 When heat is introduced into the space, heat due to sunlight is present in the transparent tank 120 and the inverted conical reflector 140, so that the solar heat can be utilized for hot water or indoor heating as described above.

That is, when water is supplied from the water supply or air supply hose 122 extending from the outside of the transparent tank 120 to the inlet 124 formed at the lower end of the inverted conical reflector 140, The water is filled in the inverted conical reflector 140 and the water is heated by the solar heat existing in the inverted conical reflector 140 to become hot water. Then, the hot water flows over the upper part of the inverted conical reflector 140 to form the transparent tank 120 and the inverted conical reflector 140, the water is discharged through the outlet 128 formed at the upper end of the transparent tank 120 to the place where the hot water is used, thereby providing not only the winter season but also the advantage of using hot water throughout the seasons.

On the other hand, when air (outside air) is supplied from the water supply or air supply hose 122 extending from the outside of the transparent tank 120 to the inlet 124 formed at the lower end of the inverted conical reflector 140, The space inside the reflector 140 and the space between the transparent tank 120 and the inverted cone reflector 140 are filled with air and heated by the solar heat and the heated air is supplied to the outlet 128 So that indoor heating can be performed in the winter without requiring a separate fuel cost.

The water or the external air supplied as described above undergoes heat exchange with the solar heat inside the inverted conical reflector 140 and the transparent tank 120 so that the temperature of the interior of the inverted conical reflector 140 and the transparent tank 120 becomes appropriate ≪ / RTI >
