Construction method of Sunlight device with 3 dimensional movement reflective mirror

The present invention relates to a construction method of a three-dimensional reflection mirror type light emitting device that irradiates sunlight using a reflection mirror on a lower floor of a building that is not directly irradiated with sunlight, and more particularly, X, Y, Z, The solar tracking unit that adjusts the angle of the axis to allow more sun light to be irradiated into the shaded area and accurately tracks the position of sunlight according to the illuminance of the sunlight according to the distance between the condenser lens and the position tracking sensor. It is provided with a distance adjusting means for automatically adjusting, and equipped with an infrared cut-off member for preventing the temperature inside the housing rises above a certain temperature, and three-dimensional that allows the angle adjustment in the virtual X, Y axis direction of the housing It relates to a construction method of the reflection mirror type light mining device.

Recently, as grievous buildings enter the city center, there are increasing shaded areas where sunlight is not directly irradiated on buildings located relatively low or north. Residents of buildings that are not directly irradiated with sunlight are often suffering from diseases such as sunshine deficiency syndrome due to lack of sunshine, and since sunlight does not come in, it is necessary to use them as lighting equipment such as fluorescent lamps in daylight. Consumption is happening.

For this reason, in recent years, various solar light mining devices have been proposed in an effort to secure a sunshine amount for a predetermined time or more.

The solar photovoltaic device is a natural energy utilization device that is expected to be introduced and expanded in the future as a device for preventing global warming, saving energy, and benefiting residents' health.

Prior arts related to solar light mining devices include Patent Publication No. 2006-100954, "Solar reflecting device and method using a mirror installed on a building wall", Patent No. 729721, "Natural light device" and the like.

The solar photovoltaic device includes a reflection mirror for reflecting the incident sunlight and an angle adjusting means for adjusting the angle of the reflection mirror to direct the light reflected from the reflection mirror to the shadow area to be irradiated. . The prior art also includes such a component.

The problem is to increase the efficiency of solar photovoltaic devices by accurately measuring the current position of the sun and controlling the angle adjusting means more precisely. The patent discloses that the central computer measures the altitude and azimuth angle of the sun, and it is not known in detail by any means, and the registered patent also states that the angle of reflection mirror and sunlight is controlled. There is only. In addition, it is questionable whether the position of the sun (altitude and azimuth angle) can be accurately measured in the case of poor sunlight such as a cloudy day.

In addition, Korean Patent Publication No. 2001-60471 discloses a solar tracking sensor using a photodiode.

The prior art 1 includes four photodiodes for tracking the azimuth and elevation angles of the sun, and tracks the position (azimuth and elevation angles) of the sun by comparing the intensity of light incident on each photodiode.

The prior art 1 has a problem that the tracking of the sun is not properly made when the sunlight is weak, such as morning and evening or cloudy days. In order to solve this problem, Korean Patent Laid-Open Publication No. 2003-62374 "A solar tracking device using a lens" has been proposed in the related art.

In the solar tracking device using the lens, the position of the lens is arranged on the upper part of the housing to collect incident light and transmit the light to the photodiode so that the position of the sun can be tracked even on a cloudy day.

However, the prior art 2 includes a risk that the solar position tracking may not be properly performed due to a malfunction or burnout of the sensor when the illumination is high at midday on a clear day.

In other words, the photodiode will be placed close to the focal length of the lens on a cloudy day, so more sunlight is concentrated by the lens and entering the photodiode at midday on a sunny day. The photodiode will concentrate more sunlight than necessary and the surface temperature will rise rapidly.

When the surface temperature of the photodiode increases, the photodiode may malfunction, and in severe cases, it may be burned out and lose its function.

Therefore, the photodiode should be placed close to the focal length of the lens on a cloudy day with little sunlight to increase the accuracy of the sun tracking and prevent the malfunction or malfunction. On clear days, the photodiode needs to stay away from the focal point of the lens for more sunlight than it needs to concentrate.

However, the prior art 2 is not equipped with such a means.

By condensing light using a lens, more light is concentrated on the photodiode. In particular, the infrared rays of the concentrated light rapidly increase the surface temperature of the photodiode. Then, the photodiode is likely to malfunction or burn out due to temperature rise. Therefore, in order to increase the accuracy of solar tracking, and to prevent the photodiode from malfunctioning, it is necessary to adjust the distance between the infrared ray and the lens and the photodiode according to the illumination. However, the prior art 2 lacks such a means.

The present invention has been made to solve the above problems, to improve the efficiency of the mining system by adjusting the angle of the reflection mirror by accurately measuring the position of the sun on a cloudy day as well as a sunny day,

It automatically adjusts the separation distance between the condenser lens and the position tracking sensor (photodiode) according to the intensity of sunlight (light intensity) to increase the accuracy of the tracking of the sun even on a cloudy day and cause malfunction or burnout due to rapid temperature rise. It is provided with a distance adjusting means so as not to occur, and since the infrared rays are the main culprit among the sunlight, it is equipped with an infrared ray blocking member that blocks infrared rays among the light incident through the lens, and adjusts the focal length according to the illuminance for the position tracking sensor. (I.e. photocell) is prevented from malfunctioning or burning, and even after fixing the solar tracking unit, the user can easily adjust the installation angle of the housing arbitrarily, and converts the analog signal transmitted by the position tracking sensor into a digital signal. By injecting noise into the signal transmission process, the accuracy of the sun and tracking is reduced. To prevent that,

The purpose of the present invention is to provide a method of constructing a three-dimensional reflective mirror type solar photovoltaic device with improved reflection efficiency with the sun by rotating the reflection mirror in the X-axis, Y-axis, and Z-axis according to the position of the sun. It is done.

Then, the sun's light is irradiated to the lower shaded areas of the building through the first, second and third reflection mirrors.

The first, second, and third reflection mirrors may be angle-adjusted, respectively, and the first reflection mirror may automatically adjust angles of the X, Y, and Z axes through the angle adjusting means and the solar tracking unit.

Figure 2 shows an example of the angle adjusting means.

The angle adjusting means 100 rotates the reflecting mirrors R1, R2, and R3 (particularly the first reflecting mirror R1) on the X, Y, and Z axes, respectively, so that the position of the sun is changed over time. As a result, the light reflected from the reflection mirrors R1, R2, and R3 can be irradiated to the target shaded area even though it is continuously changed.

Pedestal 110 is fixed to the bottom surface, '' 'shaped frame 120 is rotatably coupled to the Z axis on the top of the pedestal, and is rotatably coupled to the X axis on the top of the frame, The reflective mirror (R1, R2, R3) comprises a horizontal bar 130 is rotatably coupled to the Y side.

It is preferable to control the motors of the angle adjusting means equipped with the second reflecting mirror and the third reflecting mirror so that the light is irradiated to the shadowed area more accurately through the second and third reflecting mirrors.

 3 to 6 illustrate a solar tracking unit that tracks the position of the sun and transmits the tracked information to the controller.

Figure 3 is a cross-sectional view of the solar tracking unit according to the invention, Figure 4 is a perspective view without the controller, Figure 5 is an exploded perspective view of Figure 4, Figure 6 is a schematic block diagram of the controller.

3 to 5, the tracking unit S of the present invention has a cylindrical housing 10, a condenser lens 61 is disposed at an upper opening of the housing 10, and the housing 10. A position tracking sensor 67 made up of a plurality of photocells is disposed in the lower opening of the door, and a distance adjusting means for adjusting the separation distance between the condenser lens and the position tracking sensor by raising and lowering the position tracking sensor 67 inside the housing. It is provided. The distance adjusting means includes a lifting pin 81, the motor 82, the illumination sensor 85, the base 83, the guide rod 84, the controller 70 shown in Figs. It is the collective definition of the module.

And the solar tracking unit (S) may be preferably built in the waterproof cover 90 as shown in Figure 3 so as not to come in contact with rain water to enhance the durability. The waterproof cover 90 includes a receiving member 91 in which the solar tracking unit is accommodated and a cap 96 covering an upper opening of the receiving member.

That is, the waterproof cover 90 is composed of a receiving member 91 to accommodate the solar tracking unit and a cap 96 covering the upper opening of the receiving member, the upper outer periphery of the receiving member and the cap The lower inner periphery is formed with thread tabs 92 and 97 engaged with each other and screwed together.

And the upper end of the receiving member is provided with a plurality of fixing projections (93) radially protruding formed to be seated in the fixing groove 31 formed on the edge of the bracket 30 of the solar tracking unit mounted on the top of the cap, The lower inner surface is formed with a fixing piece 98 for contacting and pressing the upper surface of the edge of the bracket.

In addition, a plurality of bolt holes 94 are formed at the lower end of the receiving member to fix the receiving member using bolts, and the side of the receiving member penetrates a through hole 95 through which a cable electrically connecting the controller 70 to the controller. ) Is formed.

The condenser lens 61 condenses the light incident as the convex lens to focal light so that more light is incident on the position tracking sensor 67, so that the position tracking of the sun with less sunlight is possible, such as on a cloudy day. .

The position tracking sensor 67 is a sensor that outputs an electrical signal according to a change in the amount of incident sunlight (light intensity), and a photocell such as a photodiode is usually used. The size of the electromotive force output by the photocell depends on the intensity of the incident sunlight. The position tracking sensor 67 is mounted on the board 69, and a plurality of pins are provided on the lower surface of the board for transmitting electrical signals of each photocell constituting the position tracking sensor 67 to the controller 70. 68 are provided.

The position tracking sensor 67 tracks the position of the sun by radially arranging a plurality of photocells.

More specifically, when comparing the electromotive force generated by two photocells arranged in the imaginary X-axis direction (left and right), that is, in the azimuth direction of the sun, if the values are different from each other, the sun is biased toward the smaller electromotive force. In addition, the housing 10 is rotated in one direction of the X axis so that the electromotive force generated by the two photocells is driven by driving the motor.

  Similarly, the electromotive force generated by the two photocells arranged in the imaginary Y-axis direction (front and rear), that is, in the direction of the altitude angle of the sun, is compared and the housing 10 is rotated on the Y-axis so that the values are smaller. The generated electromotive force is the same.

As described above, the electromotive force between photocells arranged parallel to the virtual X-axis direction among the plurality of photocells is compared with each other to track the azimuth angle of the sun, and the electromotive force between the photocells arranged parallel to the virtual Y-axis direction is mutually compared. By comparison, the sun's elevation is tracked.

If the electromotive force of all photocells is within a certain range of error, the housing 10 will face the sun.

Distance adjusting means for adjusting the separation distance between the condenser lens 61 and the position tracking sensor 67 is a lifting pin 81, the motor 82, the illumination sensor 85, the base 83, the guide rod ( 84), including the controller 70.

One end of the elevating pin 81 is fixed to the board 69 on which the position detecting sensor 67 is mounted, and is moved up and down by the motor 82 to track the position mounted on the board 69. The sensor 67 is moved up and down to adjust the distance between the condenser lens 61 and the position tracking sensor 67.

The illuminance sensor 85 receives sunlight and detects illuminance (intensity of sunlight), and transmits the sensed illuminance to the controller 70. The illuminance detection sensor 85 is preferably installed to face the sun at all times to enable accurate illuminance detection, and for this purpose, the present invention is installed on the outer upper surface of the housing as shown.

The base 83 is disposed inside the housing 10 (more accurately, inside the insertion member 20), and the motor 82 is mounted on one surface of the housing 83.

The guide rod 84 serves to prevent the board 69 from tilting when the board 69 is raised and lowered. If the board 69 is tilted, the photocells of the position tracking sensor 67 do not see the sun in front, even if the housing 10 is in front of the sun. As a result, the intensity of sunlight incident on each of the photocells should be the same, but different, so that accurate solar position tracking is not possible.

A plurality of the guide rods 84 are radially arranged and coupled to the base and inserted into guide holes (not shown) drilled in the board 69, so that the board 69 is horizontal. Ascending and descending along the guide rod (84).

The controller 70 receives the illuminance sensed by the illuminance sensor 85 and rotates the motor forward or reverse according to the illuminance. A more detailed description of the controller 70 will be described later.

The position tracking sensor 67 is mounted on the upper portion of the insertion member 20, as shown in the drawing, the insertion member 20 is a structure that is screwed into the lower opening of the housing 10 Therefore, the user can arbitrarily adjust the distance between the condenser lens 61 and the position tracking sensor 67.

And the washer member 25 is fitted to the outer periphery of the insertion member 20 so that the insertion member 20 is not inserted into the housing 10 more than a predetermined depth, the insertion member which is screwed to the housing 10 ( 20) is not easily separated.

One example of screwing the insertion member 20 and the housing 10, and after inserting the insertion member 20 into the housing 10 may be fixed to them by a bolt or the like.

And the upper portion of the insertion member 20 is installed so that the position tracking sensor 67 is not exposed to the outside, the protective glass 65 for preventing the position tracking sensor 67 from being damaged by accidental impact is mounted. have.

In addition, an infrared ray blocking member 63 for blocking infrared rays is disposed inside the housing 10 between the condenser lens 61 and the position tracking sensor 67.

The infrared ray blocking member 63 reflects the infrared rays of the light incident through the condenser lens 61 and emits them to the outside through the condenser lens 61, so that the temperature inside the housing 10 rises rapidly and the position tracking sensor (67) prevents malfunction.

As shown in the drawing, a support member 62 is interposed between the condenser lens 61 and the infrared ray blocking member 63 to support the condenser lens 61.

As shown in the drawing, the bracket 30 for fixing the housing 10 has a screw hole 33 for fixing the bracket 30 on one side of the bracket 30 and the housing 10 on the other side. The insertion hole 31 to be inserted is formed.

Three joining holes 32 are radially arranged around the insertion hole 31 of the bracket 30, and wing portions 11 are formed at the outer circumference of the housing 10, and the wing is formed. The coupling hole 12 is formed in the portion 11 at a position corresponding to the coupling hole 32.

In addition, a long rod-shaped fixing member is inserted into the coupling hole 32 and the coupling hole 12 to connect the bracket 30 and the housing 10. The fixing member may be, for example, a bolt 41 having a predetermined length and a nut 42 tightening the bolt 41 as shown in the drawing.

The inner diameter of the insertion hole 31 is larger than the outer peripheral outer diameter of the housing 10. Thus, the housing 10 is movable in the virtual Z-axis direction, and can be inclined to a certain range in the virtual X-axis and Y-axis directions.

In addition, a plurality of coil springs are interposed between the wing portion 11 and the bracket 30 as the elastic member 50 to prevent the housing 10 from swinging due to wind or external impact.

In this way, the inner diameter of the bracket 30 insertion hole 31 is larger than the outer diameter of the housing 10, the elastic member 50 is interposed between the wing portion 11 and the bracket 30, and the wing portion 11 and By adjusting the distance between the wing portion 11 and the bracket 30 through each of the three fixing members 41 and 42 connecting the bracket 30,

The user can adjust the inclination of the housing 10 in the X-axis and the Y-axis, or adjust the position in the Z-axis by only tightening or loosening the fixing members (ie, adjusting the length). Therefore, even after the solar tracking device is fixed to a specific device, the user can easily adjust the housing 10 in the X, Y, and Z directions in a certain range.

Figure 6 receives a signal from the position tracking sensor 67 and the illumination sensor 85, driving the motor 82 of the distance adjusting means in accordance with the input signal, the angle adjusting means 100 according to the present invention described above ) Is a schematic block diagram of a controller 70 for transmitting information to a control unit (C) unit that rotates () in a specific direction.

As shown in the figure, the amplifier 71 includes a comparator 73, a comparator 73, an AD converter 75, and a microcomputer 77.

The amplifier 71 amplifies a signal (electromotive force or current) input from the photocell of each position tracking sensor 67.

The comparator 73 compares the magnitudes of the signals of the amplified photocells. As described above, the signal sizes between the virtual X axis and the photocells arranged parallel to the virtual Y axis are compared with each other.

The AD converter 75 converts the analog output signal of the comparator 73 into a digital signal. The conversion into a digital signal is to prevent the motor from malfunctioning by distorting the signal due to noise flowing in the signal transmission process, and is particularly advantageous for long-distance transmission of the signal.

The microcomputer 77 has a signal input through the AD converter 75 and outputs a signal for solar tracking to the controller C. The controller C receiving the signal of the microcomputer 77 rotates the angle adjusting means 100 according to the present invention in a specific direction so that the sunlight is continuously irradiated into the shaded area.

When the microcomputer 77 or the controller C stores data in the tracking path according to the time of the last day, when the light is not incident on the position tracking sensor 67 or the incident light is too weak, accurate position tracking is impossible. It drives the angle adjusting means 90 in a specific direction with time by the stored data.

In addition, the microcomputer 77 receives the illuminance sensed by the illuminance sensor 85, and drives the motor 82 of the distance adjusting means according to the received illuminance, thereby providing the position tracking sensor 67 and the condenser lens. Adjust the separation distance of (61).
