Description

Detailed Description of the Invention

  The present invention relates to a solar battery panel watering system that sprays water toward a solar battery panel installed on a roof of a building, and a watering tile used in the solar battery panel watering system.

  In recent years, from the viewpoint of energy saving and the like, introduction of a photovoltaic power generation system has been promoted even in ordinary households. In such a power generation system, power is generated by irradiating sunlight onto a solar cell panel installed on the roof of a building. However, if dust such as dust or yellow sand accumulates on the solar cell panel, power generation may be hindered, or if sunlight becomes stronger and the temperature of the solar cell panel itself increases in midsummer, the power generation efficiency may decrease. is there.

  Therefore, a water spray pipe is horizontally arranged above the solar battery panel, and water is sprayed from the plurality of holes formed in the water spray pipe toward the solar battery panel, thereby cooling the solar battery panel and removing yellow sand and the like. A method is known (see, for example, Patent Document 1). Moreover, the watering tile which sprinkles water toward the solar cell panel installed in the roof of a building is proposed.

  However, sprinkler pipes installed outdoors such as on the roof are subject to direct sunlight and wind and rain, so they deteriorate quickly and have a problem in durability. In addition, when the water spray pipe freezes in winter, there arises a problem that water cannot be sprayed. In order to prevent the water spray pipe from freezing, it is conceivable to wrap the water spray pipe with an anti-freezing tape. However, since such anti-freezing tape is further deteriorated, the anti-freezing tape is attached to the water spray pipe installed on the roof. It is unrealistic to wrap, and no measures have been taken against freezing of the water spray pipes. Furthermore, dust such as fallen leaves is likely to accumulate between the water spray pipe and the roof, and the aesthetic appearance is impaired. Moreover, if rainwater is dammed up by accumulated fallen leaves or the like, it may cause rain leakage. In addition, the watering tiles have excellent durability and excellent effect in preventing freezing in winter. However, when a lot of snow falls, the watering nozzle surface may be covered with snow.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a solar cell panel watering system according to the present invention and watering tiles used therein will be described with reference to the drawings. In the following description, for the sake of convenience, the vertical direction and the front-back direction of the watering tile are defined based on the state where the watering tile is placed on a horizontal plane. Therefore, the vertical direction and the front-rear direction of the watering tile in a state where the watering tile is installed on an inclined surface such as a roof (the state of FIG. 1) do not exactly match.

  In FIG. 1, a solar cell panel watering system A in the present embodiment includes a solar cell panel C installed on a roof material B, a plurality of watering tiles 10 that spray water toward the solar cell panel C, and each watering tile 10. And a water supply pump (not shown) for supplying water.

  As shown in FIG. 1, the roof material B is arranged with a predetermined angle with respect to a horizontal plane, and a plurality of talc 21 arranged at predetermined intervals in the horizontal direction, and a field plate installed on the talc 21. 22, a waterproof sheet 23 that covers the base plate 22, a plurality of pedestals 24 that extend horizontally on the waterproof sheet 23, and a plurality of roof tiles 25 that are provided on the pedestal 24. The solar cell panel C is a roof-mounted type supported by a gantry 25a provided on the roof tile 25, and is arranged such that its light receiving surface has a predetermined angle with a horizontal plane.

  The plurality of watering tiles 10 are installed in a row at a predetermined interval in the horizontal direction above the solar cell panel C, and are connected to a common water supply pump (not shown) via the water supply pipe 11. The water supply pipe 11 includes a downstream water supply pipe 11a, an upstream water supply pipe 11b, and a connection portion 11c that connects the downstream water supply pipe 11a and the upstream water supply pipe 11b.

  As shown in FIGS. 1 to 3, the watering tile 10 includes a tile body member 12, a downstream water supply pipe 11 a, and a watering nozzle 13 connected to a downstream end portion of the downstream water supply pipe 11 a. The tile main body member 12 includes a tile member 14 installed on the roof and a lid member 15. An opening 140 is formed in the roof tile member 14, and the lid member 15 is formed on the outside of the roof tile member 14 so as to cover the opening 140, and from the top of the lid member 15 to the front of the roof tile body member 12. A flange 151 is formed so as to protrude from the top.

  As shown in FIGS. 2 and 3, the roof tile member 14 and the lid member 15 are formed separately. A wall surface 141 standing upward is formed around the opening 140 of the roof tile member 14. The base portion 150 of the lid member 15 is fitted so as to be in close contact with the wall surface portion 141, and the lid member 15 is installed so as to cover the opening portion 14. The wall surface portion 141 is raised so that rainwater flowing from the upper portion does not enter the opening portion 140.

  The downstream water supply pipe 11 a of the water supply pipe 11 is accommodated in the lid member 15 so as to extend outward from the roof tile main body member 12 through the opening 140. The downstream end of the downstream water supply pipe 11 a is bent in the direction toward the roof tile member 14, and extends so as to be exposed from below the flange portion 151. The downstream water supply pipe 11a in the lid member 15 is fixed by a fixing member 15a. The water spray nozzle 13 is connected to the tip end of the water supply pipe 11 extending so as to be exposed below the flange portion 151, and the nozzle surface 13 a is formed to be exposed in front of the roof tile body member 12. Water is sprayed from the nozzle surface 13a toward the solar cell panel C.

The watering nozzle 13 is arranged so that the nozzle surface 13a faces forward, and the downstream side water supply pipe 11a connected to the watering nozzle 13 passes through the opening 140 to the outside of the roof tile body member 12 (the back of the roof) 1) and is connected to the water supply pump via the connecting portion 11c and the upstream water supply pipe 11b. The watering nozzle 13 may be, for example, an exposed nozzle VS type (manufactured by SUS) manufactured by Hokuetsu Snow Machine Co., Ltd.
Thus, since the watering nozzle 13 is located on the lower side of the flange portion 151, it is difficult for fallen leaves or the like to be attached to the nozzle surface 13a, and the nozzle surface is difficult to be covered with snow. Is.

  When the base portion 150 of the lid member 15 is fitted on the wall surface portion 141 of the roof tile member 14, a packing for sealing the gap between the two may be provided as necessary. Thus, in order to prevent rainwater or the like from entering the back of the cabin through the opening, packing is provided as necessary.

  The shape and size of the tile member 14 in the present embodiment are substantially the same as the roof tile 25. That is, the tile member 14 (sprinkling tile 10) has substantially the same planar contour shape as the roof tile 25, and can be installed on the roof instead of the roof tile 25. The watering tile 10 may be either a Japanese tile type or a Western tile type.

  In the solar cell panel watering system A configured as described above, water supplied from a water supply pump (not shown) through the water supply pipe 11 is supplied from the nozzle hole formed in the nozzle surface 13a of the watering nozzle 13 to the solar cell. Water is sprayed toward the light receiving surface of panel C. The water sprayed in this way flows down along the light receiving surface, thereby washing and cleaning the dust adhering to the surface and cooling the solar cell panel C. In addition, the watering nozzle 13 is configured to have a predetermined height so that water from the watering nozzle 13 is reliably watered on the light receiving surface of the solar battery panel C.

  Next, the attachment method to the roofing material B of the watering tile 10 comprised in this way is demonstrated. Since the tile member 14 has substantially the same shape and size as the roof tile 25, the watering tile 10 can be installed on the roof material B instead of the roof tile 25. When installing the watering tile 10, first, the position where the watering tile 10 is attached is determined, and one roof tile 25 at this position is removed to expose the waterproof sheet 23. Next, the auxiliary plate 30 is mounted on the upper surface of the waterproof sheet 23, and the auxiliary plate 30 is fixed to the talc 21 using a screw (not shown). Next, a through-hole 31 that penetrates the auxiliary plate 30, the waterproof sheet 23, and the field plate 23 in the vertical direction (thickness direction of the waterproof sheet 23) is drilled. At this time, the through-hole 31 is formed at a position communicating with the opening 140 when the watering tile 10 is installed at a predetermined position.

  Next, the roof tile member 14 is installed at a predetermined position on the auxiliary plate 30 and fixed to the pier 24 with a fixture (not shown). When the lid member 15 is installed so as to cover the opening 140 of the roof tile member 14, the downstream water supply pipe 11 a connected to the water spray nozzle 13 is inserted into the opening 140 from above. The screw 16 is inserted into a through hole provided in the base portion 150 of the lid member 15 and screwed into the auxiliary plate 30, whereby the lid member 15 and the roof tile member 14 are screwed to the auxiliary plate 30. At this time, a washer and rubber packing are interposed between the screw 16 and the upper surface of the base portion 150.

  After installing a plurality of watering tiles 10 in a row in the horizontal direction on the roof material B by the above-described method, the downstream water supply pipe 11a extending to the back of the shed below the roof material B is installed in a predetermined position. The installation work of the entire solar cell panel watering system A is completed by connecting the upstream side water supply pipe 11b connected to a water supply pump (not shown) through the connection portion 11c. In addition, what is necessary is just to set suitably the number of the watering tiles 10 to install, and an installation space | interval according to the length and number in the horizontal direction of the solar cell panel C, and the water sprayable range by the watering nozzle 13. For example, in the solar cell panel watering system A in which a plurality of solar cell panels C having a width of 60 to 100 cm are laid in the horizontal direction, a plurality of roof tiles 25 corresponding to the full width in the horizontal direction of the plurality of solar cell panels C. Even if the tiles 25 are replaced with the watering tiles 10 at a ratio of two or three, the water can be sprayed over the entire width of the solar cell panels C.

  As described above, according to the solar cell panel watering system A in the present embodiment, the downstream portion of the water supply pipe 11 (downstream water supply pipe 11 a) is covered with the roof body member 12 of the water spray tile 10 and the water supply pipe 11. Since they are connected to the water pump through the shed, they are not directly exposed to direct sunlight or wind and rain. Thereby, deterioration of the water supply pipe | tube 11 can be suppressed and the durability of the solar cell panel watering system A can be improved. Moreover, since the downstream site | part of the water supply pipe | tube 11 is covered with the tile main body member 12, it can prevent that these freeze and it becomes impossible to water. Furthermore, even if the outside air temperature becomes below freezing in midwinter, it is rare for the back of the hut to drop below freezing. Therefore, the water supply pipe 11 can be prevented from freezing by arranging the water supply pipe 11 behind the hut. In order to prevent the water supply pipe 11 from freezing more reliably, it is conceivable to wrap an antifreeze tape around the water supply pipe 11 extended in the back of the hut. Therefore, the deterioration of the antifreezing tape can be avoided.

  Moreover, since the water supply pipe 11 (downstream side water supply pipe 11a) is extended to the lower part of the roof material B through the opening part 141 formed in the tile main body member 12, and is connected to the water supply pump through the back of the hut, It is not necessary to extend the water supply pipe 11 along the upper surface of the roof material B. Therefore, the fallen leaves and the like are accumulated between the water supply pipe 11 and the roof material B, so that the aesthetic appearance is not impaired and it does not cause rain leakage. And since the roof tile member 14 and the cover member 15 are configured separately, the construction is easy, and during the maintenance, the removal and the like are good, and the maintenance becomes easy.

  As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form, without being limited to the said embodiment. For example, as shown in FIGS. 4 and 5, the roof tile member 14 and the cover member 15 may be integrally formed.

  In the above embodiment, the cover member 15 of the tile main body member 12 has been described as being made of metal (stainless steel), but may be made of weather resistant resin or ceramic. Moreover, in the said embodiment, although the solar cell panel C demonstrated to the roof mounting type | mold supported by the mount frame 25a provided in the roof tile 25 as an example, when a flat plate tile integrated type solar cell panel is used, it is high. It is also possible to use the watering roof tile 10 configured to suppress this. Furthermore, although packing was used in the said embodiment, it can replace with this and can also use caulking. Moreover, in the said embodiment, although the tile main body member 12 was set as the structure which has the tile member 14 and the cover member 15, this invention is not limited to this.

  In addition, the solar cell panel watering system A and the watering tile 10 according to the present invention can be used not only for watering for the purpose of cooling and cleaning the solar cell panel C but also for watering for snow melting, for example.
