Description

  The present invention relates to a heliostat device including a reflecting mirror or a solar battery panel.

In the past, energy has been obtained from fossil fuels such as petroleum. In recent years, however, these fossil fuels have been depleted, greenhouse gases such as carbon dioxide emitted from the use of these fossil fuels, and also for the purchase of fossil fuels. Cost (fuel cost) is a problem.
Therefore, sunlight that can be regenerated and does not require fuel costs has attracted attention as one of new energy sources.

As an apparatus using this sunlight as an energy source, for example, a solar power generation apparatus including a solar cell module (solar cell panel) can be cited. There are two types of solar cell panels in which the installation angle is fixed (fixed type) and those that can be adjusted in accordance with the movement of the sun (solar tracking type) (Patent Document 1).
Moreover, in the case of the thing provided with the reflective mirror, a solar thermal collector is mentioned, for example, there exists a tower type thing. A heliostat device adjusts the angles of the reflecting surfaces of a plurality of reflecting mirrors arranged around the tower, condenses sunlight on a receiver provided on the tower, and collects solar heat.

JP 2003-322418 A

  Here, the fixed type panel of the solar power generation device has the maximum power generation amount when the sun goes south, and is almost zero immediately after sunrise and just before sunset. The amount of power generation gradually increases after sunrise, reaches a maximum in the middle of the south, gradually attenuates as the sun tilts west, and becomes almost zero just before sunset. Thus, the power generation amount of the fixed type changes like a bell during a day.

  Further, in Japan, the amount of power generation can be slightly increased by installing the fixed panel in a south direction at an inclination angle of 20 to 30 ° as a way of placing the fixed panel. This is due to the fact that the solar altitude fluctuates approximately 50 ° in summer and winter in the middle and south, and in Japan it decreases to nearly 10 ° in winter, so a 35 ° tilt is optimal.

However, in practice, when the inclination angle is close to 30 °, the shadow formed by the fixed panel in the front row comes into contact with the fixed panel in the rear row (shadow interference). When a shadow is generated on a part of the surface of the solar battery panel, the connection system of the power generation cells may be short-circuited for each series, and the amount of power generation may be reduced in an area larger than the shadow size. Therefore, it is necessary to leave a gap between the front row and rear row panels.
As for the size of the gap, the optimum angle and gap are selected based on the balance between the loss due to the shadow and the increase due to the inclination angle. Actually, the size of the gap is determined so that shadows cannot be made after 9 am.

In the first place, obtaining the maximum solar energy can be achieved by completely covering the entire area of the land where the solar panel is to be installed with the solar panel, so that sunlight does not illuminate the ground at all.
However, in actuality, this kind of laying method cannot be performed in this way because access roads to the fixed panels cannot be obtained, and failure, maintenance, and installation work cannot be performed.

In order to secure the access road, it is necessary to provide a gap, and at the same time, considering the “solar altitude at the time of the south and the middle when the solar panel is facing the sun on average throughout the year” At present, it is installed with a gap between the front row and the rear row at an angle of 0.3 to 0.4 as the access road with respect to the site area.
“Solar altitude at the time of the solar power where the solar panel is facing the sun on average throughout the year” is spring equinox and autumn equinox, but in Tokyo, Japan, it is 53.6 ° and the inclination angle of the panel is 90-53. .6 = 36.4 °. However, considering the shadows that can appear in the back row in the morning and evening, it is necessary to increase the gap or set the tilt angle lower.

However, if the gap is made too large, the area of the gap will exceed the minimum required area for the access road, and the excess will be a wasteful ground that does not generate electricity at all, so measures to increase the gap are taken. Absent.
On the other hand, in order to prevent shadows from always occurring, the inclination angle should be zero, but the access road cannot be taken.
As a result of these, an inclination angle of 10 to 30 ° is selected. The gap between the front row and the rear row is taken so that the shadow of the front row does not hit the back row during winter solstice, and it is used as an access road.

  As mentioned above, access roads are indispensable for the method of installing solar panels fixed on a large scale with mega solar, which makes it impossible to avoid a decrease in power generation efficiency per land area. ing.

  In the first place, as mentioned above, the amount of power generated by a fixed solar panel changes like a bell during the day, so instead of this, the fixed type that the amount of power generated is constant from 9:00 am to the evening. A solar cell panel installation method different from the above is desired. Moreover, if the solar panel can be operated so that the influence of shadows can be suppressed in response to the ever-changing sun and at the same time, the place where the sun hits the ground, the amount of power generation per land is increased. It is possible to do this, and it has great significance in the development of renewable energy at high land costs like Japan.

Further, since the solar tracking type solar cell panel can face the sun, when it is oriented so as to be perpendicular to the sun, it is possible to obtain a power generation amount equivalent to that in the south-central time.
The conventional solar tracking type is called a graticule type, and as shown in FIG. 8, a power generation panel comprising a solar cell panel and a frame that supports the solar cell panel is supported by a support column. The power generation panel can be moved up and down and left and right with the vertical rotation means and the left and right rotation means always facing the sun.

  However, the solar cell panel in the front row casts shadows on the solar cell panel in the back row from the sunrise when the solar altitude is low until around 9 o'clock and after about 4 o'clock before sunset. The amount will decrease. Therefore, for example, each solar cell panel is arranged separately, but this needs to be arranged apart from the case of the fixed type panel, and land use efficiency becomes low, and power generation efficiency decreases. Will lead to.

  Also, in the tower-type solar heat collector, etc., as described above, a plurality of heliostat devices that track the sun are arranged around the tower. Similarly, in order to prevent shadow interference, each of these heliostat devices A certain amount of space is also required between them.

  The present invention has been made in view of the above problems, and is a type that follows the movement of the sun. Even if the arrangement interval is narrowed, shadow interference is less likely to occur than conventional products, and more efficiently. An object of the present invention is to provide a heliostat device capable of obtaining solar energy.

In order to achieve the above object, the present invention comprises at least one reflecting mirror or solar cell panel that reflects sunlight, and the angle of the reflecting surface of the reflecting mirror or the panel surface of the solar cell panel depends on the movement of the sun. A heliostat device that adjusts following,
A frame that supports the reflecting mirror or the solar cell panel;
An elevation angle rotation axis having the east-west direction as an axial direction for rotating the frame in the north-south direction, and an azimuth rotation axis having the north-south direction as an axial direction for rotating the frame in the east-west direction, the elevation rotation A gyro mechanism in which an axis and the azimuth rotation axis are orthogonal to each other;
A support for supporting the frame via the gyro mechanism,
The frame and the reflecting mirror or the solar cell panel are integrally rotated in the north-south direction around the elevation angle rotation axis as a rotation axis, so that the reflecting surface of the reflecting mirror supported by the frame or the solar cell panel The angle of the north-south direction of the panel surface is adjusted,
With the azimuth rotation axis as the rotation axis, the frame and the reflecting mirror or the solar cell panel are integrally rotated in the east-west direction so that the reflecting surface of the reflecting mirror or the solar cell supported by the frame The east-west angle of the panel surface of the panel is adjusted,
The center of gravity of the power generation panel comprising the frame and the reflecting mirror or the solar cell panel supported by the frame coincides with the intersection where the elevation rotation axis and the azimuth rotation axis of the gyro mechanism are orthogonal to each other. A heliostat device is provided.

If this is the case, since it is a gyro type, the angle of the reflecting surface of the reflector and the panel surface of the solar panel (power generation) as well as the fixed type and the solar tracking type heliostat device The panel angle) can be adjusted with a higher degree of freedom.
For this reason, it can be directed to the sun even in a time zone where the solar altitude is low, and more solar energy can be obtained than the fixed type, thereby improving the power generation efficiency. Further, even if a plurality of heliostat devices are arranged side by side, shadow interference with other heliostat devices is less likely to occur than with the graduation table type. Therefore, it can be arranged with a narrower gap than that of the theodolite type, and land use efficiency can be improved and power generation efficiency can also be improved.

  Furthermore, since the center of gravity of the power generation panel coincides with the intersection (the center of the gyro) where the elevation angle rotation axis and the azimuth angle rotation axis of the gyro mechanism are orthogonal to each other, the power generation panel is smaller than the conventional graduation table type It can be easily rotated with force, and the angle of the solar cell panel can be adjusted with less power. Therefore, it is possible to operate the power generation panel by supplying power to the storage batteries etc. provided for each rather than drawing the wiring to the heliostat device and supplying power to each storage battery etc. Become.

At this time, the gyro mechanism is
A cylindrical body arranged such that the longitudinal direction is along the azimuth rotation axis;
An azimuth rotary shaft that passes through the cylinder in the longitudinal direction and is located on the azimuth rotary axis;
A connecting cover that connects both ends of the penetrating azimuth rotating shaft;
A connecting arm that connects the connecting cover and the frame;
Projecting from the cylindrical body in the short direction, and comprising a pair of elevation rotation shafts positioned on the elevation rotation shaft,
The support column includes a bearing that supports the pair of elevation rotation shafts so as to be axially rotatable.
With the azimuth rotation shaft on the azimuth rotation axis as the rotation axis, the connection cover, the connection arm, and the frame can be integrally rotated in the east-west direction,
The cylindrical body, the azimuth rotation shaft, the connection cover, the connection arm, and the frame are integrally north and south with the pair of elevation rotation shafts on the elevation rotation shaft as a rotation axis on the bearing of the support column. It can be rotatable in the direction.

  With such a configuration, it is possible to easily adjust the angle of the power generation panel with a small force.

  Further, the gyro mechanism may include an elevation angle adjustment actuator for rotating the frame in the north-south direction and an azimuth angle adjustment actuator for rotating the frame in the east-west direction.

  If it is such, the angle adjustment of the power generation panel of the north-south direction and the east-west direction can be performed simply.

  In addition, the battery may further include a storage battery that supplies power for operating the gyro mechanism.

  If it is such, even if it does not draw wiring in a heliostat device, the angle of the power generation panel can be adjusted by operating the gyro mechanism, and it can be a self-supporting type. Costs required for wiring installation and maintenance can be reduced.

  Moreover, the auxiliary solar cell panel for charging the said storage battery can be further provided.

  If it is such, it can be set as a self-supporting thing still more reliably.

  Further, a plurality of the reflecting mirrors or solar cell panels may be provided, and the plurality of reflecting mirrors or solar cell panels may be arranged in a square shape on the one frame.

  If this is the case, since the central part of the square shape is empty, even if the wind is blowing, the wind can escape from the central part, and even if the power generation panel receives the wind, the heliostat device It is hard to fall down and can suppress the power generation panel from shaking.

  As described above, according to the present invention, the angle of the power generation panel can be adjusted more easily and with a higher degree of freedom, the sun can be tracked, and the arrangement distance between the heliostat devices is narrow. Shadow interference is less likely to occur. As a result, solar energy can be obtained efficiently, and power generation efficiency and the like can be improved.

It is the schematic which shows an example of the heliostat apparatus of this invention. It is a side view which shows an example of a gyro mechanism. It is a top view which shows an example of the cylinder of a gyro mechanism. It is the schematic which shows an example of an azimuth angle adjustment actuator. It is explanatory drawing which shows the state which rotated the electric power generation panel to the west side. It is the schematic which shows an example of another aspect of the heliostat apparatus of this invention. It is the schematic which shows an example of the heliostat apparatus of this invention provided with the reflective mirror. It is the schematic which shows an example of the conventional theodolite type heliostat apparatus.

Hereinafter, the present invention will be described in detail as an example of an embodiment with reference to the drawings, but the present invention is not limited thereto.
FIG. 1 shows an example of the heliostat device of the present invention. In FIG. 1, the direction from the front to the back is the east-west direction, and the left-right direction is the north-south direction.
In addition, although the example provided with the solar cell panel is shown here, it may be provided with a reflecting mirror instead of the solar cell panel.
As shown in FIG. 1, the heliostat device 1 includes a power generation panel 2, a gyro mechanism 3, and a support column 4 as a whole. Here, the power generation panel 2 is inclined to the west.

  The power generation panel 2 includes a solar cell panel 5 and a frame 6. Here, four rectangular solar cell panels 5 are provided, but one or more solar cell panels 5 may be used, and the number, size, and shape are not particularly limited. These four solar cell panels are supported by one frame 6. The shape, material, and the like of the frame 6 can be appropriately determined each time. What is necessary is just to have the intensity | strength of the grade which supports the solar cell panel 5, and does not deform | transform even if it receives a wind etc.

  Further, the shape of the power generation panel 2 itself is not particularly limited. In FIG. 1, the power generation panel 2 as a whole has a square shape. That is, on one frame 6, four solar cell panels 5 are arranged in a square shape so as to leave a central portion. By arranging in this way, it is possible to effectively prevent the wind from blowing from the central portion of the power generation panel 2 even when the wind is blowing, and the power generation panel 2 to be shaken or toppled by strong wind.

  The support column 4 is not particularly limited as long as it can support the power generation panel 2 and the gyro mechanism 3, and the thickness, length, and the like are not particularly limited. What is necessary is just to prepare a suitable thing according to the magnitude | sizes of the electric power generation panel 2 grade | etc.,.

Next, the gyro mechanism 3 will be described. 2 and 3 show an example of the gyro mechanism. FIG. 2 is a side view of the heliostat device 1 of FIG. 1 viewed from the back side (east side). The power generation panel 2 is in a horizontal state. FIG. 3 is a plan view of the vicinity of the cylindrical body of the gyro mechanism.
As shown in FIGS. 2 and 3, the gyro mechanism 3 is connected to a frame 6, and an elevation angle rotation shaft 7 having an east-west direction as an axial direction for rotating the frame 6 (and the power generation panel 2) in the north-south direction, and And an azimuth rotation axis 8 with the north-south direction as the axial direction for rotation in the east-west direction. The elevation rotation axis 7 and the azimuth rotation axis 8 are orthogonal to each other. Further, these intersecting points coincide with the center of gravity G of the power generation panel 2 supported by the gyro mechanism 3.
The conventional pedestal table is not a gyro type, and naturally, the center of the gyro and the center of gravity G do not coincide with each other, and a considerable force is required to rotate the power generation panel. However, with the above configuration as in the present invention, the power generation panel 2 can be easily rotated with a much smaller force than before, and the angle of the solar cell panel 5 can be adjusted with less power.

Hereinafter, a more specific configuration of the gyro mechanism 3 will be described.
A cylindrical body 9 is provided so that its longitudinal direction is along the azimuth rotation axis 8. Further, an azimuth rotary shaft 10 is provided that penetrates the cylinder 9 in the longitudinal direction and is positioned on the azimuth rotary shaft 8. Furthermore, a connecting cover 11 that connects both ends of the penetrating azimuth rotating shaft 10 is provided, and a connecting arm 12 that connects to the frame 6 is provided at the tip of the connecting cover 11. .
In addition, about the connection part of the azimuth rotation shaft 10 and the connection cover 11, the connection cover 11 should just be able to rotate in the east-west direction by making the azimuth rotation shaft 10 into a rotating shaft. For example, the two are welded to each other and are completely connected to each other, and the connecting cover 11 can be rotated along with the axial rotation of the azimuth rotating shaft 10 itself.

Further, the outer shape of the cylindrical body 9 may be a prismatic shape or a cylindrical shape. Any material can be used as long as the azimuth rotating shaft 10 can penetrate the inside thereof.
Here, the connecting cover 11 has a U-shape, and includes a top plate 15 and two side plates 16 joined so as to sandwich the top plate 15. Side plates 16 are connected to both ends of the azimuth shaft 10 penetrating the cylinder 9. When the power generation panel 2 is in a horizontal state, the top plate 15 is positioned above the cylindrical mold 9.
The connecting arm 12 is connected to the side plate 16 opposite to the side joined to the top plate 15, and the frame 6 is connected to the connecting arm 12 as described above. With such a configuration, the cylindrical body 9, the azimuth rotation shaft 10, the connection cover 11, the connection arm 12, and the frame 6 are integrated.

Furthermore, it is provided with a pair of elevation rotation shafts 13 protruding in the short direction of the cylinder 9 and positioned on the elevation rotation shaft 7.
On the other hand, the support 4 is provided with a bearing 14, and the pair of elevation rotation shafts 13 are supported by the bearing 14 so as to be rotatable.

  As described above, the connection cover 11 can be rotated in the east-west direction with the azimuth rotation shaft 10 as the rotation axis, and the connection cover 11 is connected to the frame 6 and further to the solar cell panel 5 via the connection arm 12. So that they can be rotated together. That is, the power generation panel 2 can be rotated in the east-west direction, and the east-west angle of the panel surface of the solar cell panel 5 can be adjusted.

  On the other hand, on the bearing 14 of the support column 4, the cylinder body 9 can be rotated in the north-south direction with the elevation angle rotation shaft 13 as a rotation axis. The cylinder body 9 includes an azimuth rotation shaft 10 and a connection cover 11 passing therethrough. Since it is connected to the frame 6 and further to the solar cell panel 5 via the connecting arm 12, they can be rotated integrally. That is, the power generation panel 2 can be rotated in the north-south direction, and the angle of the panel surface of the solar cell panel 5 in the north-south direction can be adjusted.

  With such a configuration of the gyro mechanism 3, the power generation panel 2 can be easily and freely rotated in the east-west direction and the north-south direction on the support column 4, and the angle of the panel surface of the solar cell panel 5 can be adjusted with a high degree of freedom. it can. With such a gyro type, the angle of the panel surface of the solar cell panel 5 can be freely adjusted as compared with the conventional graduation table type, and the occurrence of shadow interference can be further prevented.

For example, consider the present invention having the power generation panel of FIG. 1 and the conventional graduation table type as shown in FIG. 8 having the same shape of the power generation panel.
In the conventional device, after adjusting the angle of the power generation panel in the north-south direction, the angle adjustment in the east-west direction can actually rotate only horizontally. That is, the lower side (and the upper side) of the power generation panel can only rotate so as to be always parallel to the ground (the height positions at both ends of the lower side are always the same).
On the other hand, in the present invention provided with the gyro mechanism as described above, the entire power generation panel can be rotated in the east-west direction after adjusting the angle in the north-south direction. That is, rotation adjustment can be performed so that the height positions of both ends of the lower side (and upper side) of the power generation panel are different from each other, and rotation adjustment can be performed so that the height positions are the same.

  As described above, even if the solar tracking type is used, the present invention can adjust the angle of the power generation panel with a higher degree of freedom than the conventional graduation table type. Therefore, even if the distance between the heliostat devices has conventionally caused shadow interference, the present invention can prevent the occurrence of shadow interference depending on the angle adjustment. That is, heliostat devices can be arranged closer to each other, and the power generation efficiency per unit land area can be improved.

  The gyro mechanism 3 further includes an elevation angle adjustment actuator 17 and an azimuth angle adjustment actuator 18. The means for rotating the power generation panel 2 in the gyro mechanism 3 as described above is not particularly limited, but if it is an actuator, it can be simply rotated by a motor drive.

  As an arrangement position of the elevation angle adjusting actuator 17, a position shown in FIG. The column 4 is attached so as to connect the lower surface side of the cylindrical body 9. When the arm 19 of the elevation angle adjusting actuator 17 is extended by driving the motor, the south side of the cylindrical body 9 can be pushed and the power generation panel 2 can be rotated to the north side. On the other hand, when the arm 19 contracts, the south side of the cylindrical body 9 is pulled, and the power generation panel 2 can be rotated to the south side.

FIG. 4 shows an example of the arrangement position of the azimuth angle adjusting actuator 18. FIG. 4 is a schematic view of the azimuth adjusting actuator 18 as seen from the north side.
An azimuth angle adjusting actuator 18 is attached so as to connect a portion protruding east from the connection cover 11 and a portion protruding from the lower surface of the cylindrical body 9. When the arm 20 of the azimuth angle adjusting actuator 18 is extended by driving the motor, the connecting cover 11 is inclined to the west side, and the power generation panel 2 can be rotated to the west side. FIG. 5 shows a state when rotating from the state of FIG. 4 to the west side. On the other hand, when the arm 20 is contracted, the connection cover 11 is inclined to the east side, and the power generation panel 2 can be rotated to the east side.
Of course, it is possible to arrange them at positions other than these, but by arranging them as shown in FIGS. In both the east-west direction and the north-south direction, each actuator can be appropriately arranged so as to obtain the required maximum inclination angle.

Moreover, as shown in FIG. 1, the storage battery 21 can be arrange | positioned, the motor of these actuators can be driven, and the electric power for operating the gyro mechanism 3 can also be supplied.
In the present invention, since the center of the gyro and the center of gravity of the power generation panel 2 coincide with each other as described above, the rotation control of the power generation panel 2 can be performed with an extremely small force. Therefore, it is possible to suppress power consumption required for rotational driving of the power generation panel 2. Therefore, unlike the conventional device, the gyro mechanism 3 is sufficiently operated by the storage battery 21 provided in each heliostat device without drawing a large-scale wiring for supplying electric power from the outside, and the power generation panel 2 The angle of the panel surface of the solar cell panel 5 can be adjusted. In terms of power supply, it becomes independent.
The cost and maintenance required for installing the wiring can be omitted, which is simple.

In FIG. 6, an example of the heliostat apparatus of another aspect is shown. In this embodiment, an auxiliary solar cell panel 22 is further provided. Here, it is arranged on the connecting cover 11. The electric power obtained by the auxiliary solar cell panel 22 can be stored in the storage battery 21. For this reason, it can be made more independent.
In addition, the arrangement | positioning location, magnitude | size, etc. of the auxiliary solar cell panel 22 are not specifically limited, What is necessary is just enough to charge the storage battery 21. FIG.

In a solar power generation device, a solar cell panel (or power generation panel) is a fixed type, a solar tracking type with a heliostat device and a graduation type, and solar energy obtained by the heliostat device according to the present invention. Consider the area required for installation.
Assuming that the solar energy obtained by the fixed type is 1, in the solar tracking type device such as the graduation table type device or the device of the present invention, the panel surface can follow the movement of the sun. -1.7 solar energy can be obtained.

Further, assuming that the area required for installing the solar cell panel in a fixed type is 1, it is considered that an area of 0.3 is necessary as an access road. That is, the fixed mold requires an area of 1.3. In the scale table type device, an area of 1.6 is required to obtain the above-described solar energy of 1.6 to 1.7. In order to prevent shadow interference, a larger area than the fixed type is required.
On the other hand, in the present invention, as described above, each heliostat device can be arranged closer to the graduation table type device, and as a whole, the required area is about the same as the fixed type, that is, about 1.3. be able to.

As described above, the heliostat device of the present invention can be installed with the same installation area as that of the fixed type, and can obtain solar energy of the same level as that of the graduation device. For this reason, power generation efficiency can be improved compared with the past.
Moreover, since the center of the gyro and the center of gravity of the power generation panel coincide with each other, rotation control can be easily performed with extremely small force.

As described above, the case where the solar cell panel is provided has been described, but a reflecting mirror may be provided instead of the solar cell panel.
FIG. 7 shows an example of a heliostat device provided with a reflecting mirror. In the heliostat device 23 of FIG. 7, four rectangular reflecting mirrors 24 are provided. Other configurations such as the configuration of the frame, the gyro mechanism, the support column, and the like can be the same. Similarly, the reflecting mirror 24 can be freely rotated in the east-west direction and the north-south direction, and the angle of the reflecting surface can be appropriately adjusted. Furthermore, substantially the same effects can be obtained, for example, the force required for rotation is small, the degree of freedom of rotation control is high, and the occurrence of shadow interference can be suppressed as compared to the conventional case.

  The present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and the present invention has substantially the same configuration as the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present invention.
