DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photovoltaic power generator in which a solar cell is disposed above a water treatment facility such as a water and sewage facility.

[0002]

2. Description of the Related Art In many cases, water treatment facilities of water and sewage facilities are installed in a large area in a place with good solar radiation conditions.
Therefore, conventionally, attempts have been made in various places to arrange a solar cell above the water treatment facility and perform solar power generation.

FIG. 9 shows an example of such a solar power generation device. In this solar power generation device, a roof frame 12 supported by a pillar 11 is installed diagonally above a water treatment pond 1 of a water supply facility, and a large number of solar cell panels 7 are mounted on the upper surface of the roof frame 12.
Is attached.

[0004]

However, the photovoltaic power generator shown in FIG. 9 has a steel pillar 11 extending from several meters to several tens of meters in height by laying a foundation on the periphery of the water treatment pond 1. Since the roof frame 12, which is also made of steel, is installed between the pillars 11 at an angle, the construction takes a large amount of time, and there is a problem that work at heights during construction is dangerous. Further, such a large-scale photovoltaic power generator has to work on the inclined roof frame 12 having a height of about 10 m above the ground when performing maintenance work on the solar cell panel 7. Not only may cause danger, but also take measures such as placing a sheet on the purified water treatment pond 1 to cure the treated water when dirt or dust on the solar cell panel 7 falls during the work. There was also a problem that the work had to be performed and the work was troublesome.

SUMMARY OF THE INVENTION The present invention has been made in order to cope with such a situation, and a solar cell panel is fitted on the upper surface of a movable cover installed in a water treatment facility, so that the installation is simple and the water treatment facility is provided. It is an object of the present invention to provide a photovoltaic power generation device that facilitates inspection and maintenance work of a solar cell.

[0006]

According to a first aspect of the present invention, there is provided a photovoltaic power generation apparatus, wherein a concave portion is formed on an upper surface of a movable cover for covering an upper part of a water treatment facility, and a solar cell panel is fitted into the concave portion. A power generator, wherein a solar cell panel is slidably fitted in a concave portion of a cover, and a resin sliding member or a rotatable slide roller protruding downward on a lower surface of the solar cell panel. Is attached.

According to the first aspect of the present invention, since the solar cell panel is mounted on the upper surface of the cover, the upper surface of the cover installed for the purpose of preventing foreign matter from entering, preventing generation of algae, preventing odors, etc. can be effectively utilized. In addition to this, large-scale construction for installing the solar panel above the water treatment facility is not required. In addition, since the solar cell panel is slid into the concave portion on the upper surface of the cover, the solar cell panel can be easily installed, and there is no possibility of the solar cell panel being detached from the concave portion due to a strong wind or the like. It can be performed. In addition, since either a sliding member made of resin or a rotatable slide roller projecting downward is attached to the lower surface of the solar cell panel, when the solar cell panel is slid into the recess, it is fitted. The sliding member reduces sliding friction with the bottom surface of the concave portion, or the slide roller rolls on the bottom surface of the concave portion to reduce friction. Therefore, the installation of the solar cell panel by sliding is facilitated, and particularly when a plurality of solar cell panels are slid, friction does not increase and it is not necessary to push the solar cell panel with a strong force. Since the concave portion of the cover functions as a rib on the upper surface of the cover, the strength of the cover can be increased. Further, since the solar cell panel can be easily maintained from the periphery of the water treatment facility or from the cover, there is no danger in the operation. Further, since the cover is movable, the solar cell panel can be moved without removing it, and the water treatment facility can be easily inspected.

According to a second aspect of the present invention, in the photovoltaic power generator, a concave wiring groove is formed on a bottom surface of the concave portion of the cover.

According to the second aspect of the present invention, the wiring cable of the solar cell panel and the wiring cable between the panels when there are a plurality of solar cell panels are stored in the wiring groove formed on the bottom surface of the concave portion of the cover. Since these wiring cables can be arranged on the back side of the solar panel, the wiring cables do not come out on the top of the cover or the upper part of the solar panel. Can be prevented from being obstructed during maintenance work.

According to a third aspect of the present invention, in the solar power generation apparatus, a plurality of covers are provided above the water treatment facility, and the connection state is established even when each cover is moved between the solar cell panels of the covers. Is maintained.

According to the third aspect of the present invention, when the cover is moved, wiring is performed so as not to interrupt the connection with the solar cell panel on another cover. Inspection work of a water treatment facility can be performed without stopping power generation by the solar cell panel.

According to a fourth aspect of the present invention, a messenger wire is stretched along the moving direction of the plurality of covers, and a wiring cable between the solar cell panels of each cover is coiled around the messenger wire. It is characterized by being wound and laid.

According to the fourth aspect of the present invention, when one of the lids is moved, the wiring cable between the adjacent lids expands and contracts the length of the coil, so that the solar cells of these lids are expanded and contracted. The connection between the panels can be maintained.

According to a fifth aspect of the present invention, a wire hook is provided on a lower surface of the solar cell panel, and a wire is passed through the wire hook and fixed to the cover.

According to the fifth aspect of the present invention, the solar cell panel can be more reliably prevented from coming off.

According to a sixth aspect of the present invention, in the photovoltaic power generation device, the concave portion of the cover is provided with a substantially constant width between both end surfaces, and an eave portion projecting inward is formed above each of the both end surfaces. Then, both ends of the solar cell panel are inserted below these eaves and fitted into the recesses.

According to the sixth aspect of the present invention, since both ends of the solar cell panel slidably fitted in the concave portion of the cover are below the eaves, the solar cell panel floats out of the concave portion and comes off. The fear can be reliably prevented. The eaves are formed integrally with the recess,
The solar cell panel may be installed by inserting the solar cell panel from either side end of the cover between this concave portion and the eaves portion and sliding it to the back. In this case, a plurality of solar cell panels can be laid side by side by sequentially sliding and pushing them.

FIG. 3 is a perspective view of the cover, FIG. 4 is a cross-sectional side view of the cover with the solar cell panel attached thereto, FIG. 5 is a cross-sectional front view of the cover for explaining a method of attaching the solar cell panel,

It is a perspective view of the cover which is an inclined surface. Components having the same functions as those of the conventional example shown in FIG. 9 are denoted by the same reference numerals.

In this embodiment, as shown in FIG. 1, a photovoltaic power generator installed in a water treatment pond 1 of a water supply facility will be described. In the water treatment pond 1, a plurality of covers 2 are provided so as to cover the upper part of the water surface in order to prevent foreign substances from being introduced into the treated water.

The cover 2 is formed by bending a rectangular glass fiber reinforced resin (FRP) plate into a cylindrical shape into a dome shape. The glass fiber reinforced resin refers to a resin obtained by reinforcing (unsaturated) polyester resin, acrylic resin, urethane resin, olefin resin, or the like with glass fibers. The cover 2 includes a small one that is disposed two at each end of the water purification pond 1 and a large one that is slightly larger than the two that is disposed at the center. As shown in FIG. 2, two rails 3 are laid on both side edges of the water purification pond 1. In addition, the small cover 2 has wheels 4 provided at the lower ends on both ends mounted on a pair of rails 3 inside both side edges of the water purification pond 1, and the large cover 2 is provided at the lower ends at both ends. The mounted wheels 4 are mounted on a pair of outer rails 3. Therefore, when these wheels 4 roll, each of the lids 2 is placed in the water treatment pond 1.
Are slidable along both side edges. Further, the small cover 2 enters the inside of the large cover 2 by sliding, or the large cover 2 covers the outside of the small cover 2 by sliding, so that these cover 2 are vertically overlapped. You can do it.

The upper part of the water treatment pond 1 is covered with a plurality of covers 2 having such a configuration. A side panel 5 shown in FIG. 1 is attached to the dome-shaped side surface of the cover 2 disposed at both ends of the water treatment pond 1.
This side portion is also completely covered. And
If the cover 2 is slid and overlapped with another adjacent cover 2, the upper surface of the water treatment pond 1 covered by the slid cover 2 is exposed, so that the treated water can easily be inspected and the tank cleaned. Etc. can be performed.

As shown in FIG. 3, a concave portion 2a is formed on the upper surface of the cover 2 so as to reach both ends along a dome-shaped curve. The concave portion 2 a is a groove-shaped concave portion having a constant width formed on the entire surface of the upper surface of the cover 2 except for both end portions. As shown in FIG. 4, a slide cover 6 having a substantially inverted L-shaped cross section along a dome-shaped curve is attached to upper portions of both end surfaces of the concave portion 2a with bolts and nuts. The slide cover 6 is a frame material having a shape in which a curved elongated glass fiber reinforced resin plate is bent in an inverted L-shape at a fold along a longitudinal direction.
The eaves 6a protrude inward from above. In addition, a concave wiring groove 2b along the dome-shaped curve is formed on the bottom surface of the concave portion 2a.

A plurality of solar cell panels 7 are fitted in the concave portion 2a of the cover 2 thus formed along the dome-shaped curved direction. The solar cell panel 7 is formed by surrounding a solar cell module with a rectangular flat plate-shaped frame, and the solar cell module generates power by being irradiated with sunlight. In this solar cell panel 7, sliding members 8 made of ultrahigh molecular weight polyethylene are screwed so as to protrude downward at four corners of the lower surface, and are mounted on the bottom surface of the recess 2a via these sliding members 8. become. The solar cell panel 7 is fitted into the recess 2a such that both ends are below the eaves 6a of the slide cover 6.

As shown in FIG. 5, the solar cell panel 7 is inserted between the recess 2a and the eaves 6a from one side end of the cover 2. Then, when the first one is inserted, the next one is inserted so as to push it from behind, and this is repeated in order to push the plurality of solar cell panels 7 all the way in. . At this time, since each solar cell panel 7 slides on the bottom surface of the concave portion 2a via the sliding member 8, the friction due to this sliding becomes small,
Until the end, the solar cell panel 7 can be pushed with relatively light force. In addition, since the wiring cable for wiring each solar cell panel 7 can be accommodated in the wiring groove 2b formed on the bottom surface of the concave portion 2a, the wiring cable protrudes outside the concave portion 2a, so that the end of the cover 2 is formed. It is no longer necessary to provide a wiring space in the water purifying treatment tank 1, and the wiring cable is not obstructed during the maintenance work of the solar cell panel 7 and the inspection work.

The solar cell panels 7 attached to these lids 2 are connected to each other via wiring cables laid between the lids 2 and are connected to a power generation control facility outside the water treatment pond 1. Is also connected. However, since the cover 2 can be manually operated, a messenger wire (not shown) is stretched over the edge of either side of the water treatment pond 1 along the sliding direction of the cover 2 so that each cover 2 Is wrapped in a coil around the messenger wire. Therefore, when one of the lids 2 slides, the wiring cable between the adjacent lids 2 expands and contracts the coil-like length, and the connection state between the solar cell panels 7 of these lids 2 is increased. Can be kept. In order to maintain the connection state between the solar cell panels 7, it is sufficient to simply provide a margin for the length of the wiring cable within the sliding range, or other wiring means may be used. When the cover 2 is slid, when the solar cell panel 7 may be stopped, a wiring cable between the solar cell panels 7 is connected via a connector, and the cover 2 is slid. In this case, the connector may be temporarily disconnected.

According to the photovoltaic power generator having the above-described structure, the solar cell panel 7 is mounted on the upper surface of the cover 2 provided for preventing foreign matter from being introduced. The energy of the radiated sunlight can be used effectively. In addition, by using these lids 2 covering the water treatment pond 1 to support the solar cell panel 7, large-scale construction for assembling the steel pillars 11 and the roof frame 12 is not required. Furthermore, since the solar cell panel 7 is fitted into the recess 2a of the cover 2 and the upper portions of both ends are supported by the eaves 6a of the slide cover 6, the attachment is secure and the inside of the recess 2a is blown by strong wind or the like. Even if it emerges, there is no possibility that it will come off the cover 2 and jump out. In addition, since the upper surface of the cover 2 is curved in a dome shape to increase the strength, it is possible for a person to ride on the cover 2 and walk, but the depression of the concave portion 2a along the dome-shaped curve is also possible. By functioning as ribs, the strength can be further increased. In addition, since the solar cell panel 7 attached to the cover 2 can be easily maintained by the operator from both side edges of the water purification tank 1 and the cover 2, there is a danger in the maintenance work. If this cover 2 is slid, the upper part of the sewage treatment pond 1 at the slid portion is opened, so that inspection work and the like can be easily performed. In addition, since these lids 2 overlap with another adjacent lid 2 by sliding, it is not necessary to provide a useless space for sliding outside the water treatment pond 1. Further, even when the cover 2 is slid, the connection between the other cover 2 and the solar cell panel 7 can be maintained by the coil-shaped wiring cable, and these solar cell panels 7 were operated. Inspection work can be performed as it is.

Further, in the above embodiment, the concave portion 2 of the cover 2 is provided.
The removal of the solar cell panel 7 fitted into the slide cover 6 is stopped by the eaves 6a of the slide cover 6.
As shown in FIG. 6, if a wire hook 9 is provided on the lower surface of each solar cell panel 7 and the wire passed therethrough is fixed to the cover 2, the solar cell panel 7 is more securely prevented from coming off. be able to.

Further, in the above embodiment, the case where the sliding members 8 are attached to the four corners on the lower surface of the solar cell panel 7 has been described. However, as shown in FIG.
By attaching the rotatable slide roller 10, the sliding of the solar cell panel 7 can be further facilitated, and the work of installing the solar power generation device can be reduced.

In the above embodiment, the case where the upper surface of the cover 2 is dome-shaped has been described. However, if a plurality of solar cell panels 7 are installed on such a dome-shaped upper surface, some solar cell panels 7 may be used. Since the incident angle of sunlight cannot be avoided to be very shallow, the power generation efficiency is not always good. For this reason, the upper surface of the cover 2 may be a horizontal surface, and if the inclined surface as shown in FIG. 8 is used, the power generation efficiency can be further improved. If the upper surface of the cover 2 is inclined by the same angle as the latitude of the installation location and the inclined surface faces south, the power generation efficiency becomes the highest. Further, in the above-described embodiment, the case where the cover 2 is made to be movable by sliding the cover 2 on the rail 3 which is a sliding support means is described, but the movable means of the cover 2 is not limited to this, and is arbitrary.

In the above embodiment, the photovoltaic power generation system installed in the water treatment pond 1 of the water supply facility has been described. However, the solar power generation apparatus may be installed in other water treatment facilities of the water supply facility or water treatment facilities such as the treatment pond of the sewerage facility. Can be similarly implemented.

[0032]

As is apparent from the above description, according to the photovoltaic power generator of the present invention, the solar cell panel is installed by effectively utilizing the space on the upper surface of the cover installed in the water treatment facility. This eliminates the need for large-scale construction. Also, by sliding the solar cell panel into the concave portion of the cover lid, the installation of the solar cell panel can be facilitated and the mounting can be ensured, and the sliding member or slide roller on the lower surface of the solar cell panel can be secured. Thereby, friction at the time of sliding can be reduced. Further, the inspection of the water treatment facility and the maintenance of the solar cell panel can be performed safely and easily. In addition, the cover can be moved for inspection of the water treatment facility without stopping the solar cell panel.
