Description

  The present invention relates to a solar cell sheet for a pipe house installed on a roof portion of a pipe house such as an agricultural greenhouse.

  In recent years, solar power generation using solar cells has attracted attention as a power supply source in consideration of the environment. For example, in buildings such as houses and factories, a facility for supplementing the power used in such buildings with solar power generation by fixing the solar cell panel to the frame placed on the roof has been put into practical use. .

  By the way, in the field of agriculture and the like, pipe houses such as agricultural vinyl houses are used because of their easy structure and easy installation. Even in such a pipe house, in addition to the operation of air conditioning equipment such as heating, cooling and ventilation in the house, electric power as drive energy is required for operation of various work equipment such as plowing, harvesting, water absorption, and fertilization. Often. Therefore, it is also considered to supplement these electric power with solar power generation.

  Here, Japanese Patent Laying-Open No. 2010-193837 (Patent Document 1) shows a greenhouse (vinyl house) having a transparent outer wall or roof on which a solar cell module is disposed. Furthermore, in patent document 1, in order to avoid the influence by the wind and rain with respect to a solar cell module, installing the solar cell module in the surface inner side of an outer wall or a roof material is described as a preferable aspect of a greenhouse.

  However, when the solar cell module is installed inside the covering sheet that covers the greenhouse, the expected amount of power generation can be obtained during the day when the incident angle of sunlight on the covering sheet is small, such as in the morning. In the time zone when the incident angle of sunlight on the covering sheet is large, such as in the evening or the evening, there is a problem that sunlight is reflected by the covering sheet and a sufficient amount of power generation cannot be obtained.

  Japanese Patent Laying-Open No. 2006-339683 (Patent Document 2) discloses a solar cell module fixing method in which a solar cell module is sewn and attached to a wall surface of a building. Further, in Patent Document 2, a simple dome-like structure is given as a specific example of a building, and a simple dome-like structure to which a solar cell module is sewn is described.

  However, the covering sheet of the greenhouse needs to be replaced every few years. When the method of fixing the solar cell to the covering sheet of the greenhouse as in Patent Document 2 is adopted, the covering sheet is sewn at the time of replacement. After releasing the attached state, it is necessary to remove the solar cell from the covering sheet, replace the covering sheet, and then re-install the solar cell. As described above, if the solar cell is directly fixed to the covering sheet, there is a problem that a great amount of time and labor are required for replacing the covering sheet.

Further, the resin film 24 continuously extends from the upper side of the one inner side wall part 40 to the upper side of the other inner side wall part 40, and then extends along the inner surface of the other inner side wall part 40. Thus, it reaches the upper side of the bottom wall portion 38 of the other locking member 30. 5 and 7, the end portion of the covering sheet 14 is superimposed on the upper surface of the fixing ear portion 32, but this is not necessary, and the resin film 24 and the covering sheet 14 may not overlap.

  Further, in the solar cell sheet 22 for pipe house, the fixing ear 32 is locked by the elastic pressing member 36 also in the locking member 30 extending in the width direction of the pipe house 10. That is, the solar cell sheet 22 for pipe houses is also locked between the locking members 30 and 30 extending in the width direction of the pipe house 10 adjacent to the solar cell sheet 22 for pipe houses, in other words, the solar cell for pipe houses. All four sides of the battery sheet 22 are locked by the locking member 30. Here, the fixing ear 32 extending in the width direction of the resin film 24 is locked by the elastic pressing member 36 between the surrounding locking members 30, and the length direction and the width direction on the upper surface of the resin film 24. The solar cell module 26 bonded to the intermediate portion is located between the surrounding locking members 30.

  The pipe house battery sheet 22 having the above-described structure and the pipe house 10 including the pipe house battery sheet 22 can exhibit the following effects. That is, in the battery sheet 22 for a pipe house in the present embodiment, the solar cell module 26 is installed in a state of being exposed to the outside, and compared with the case where the solar cell module 26 is installed inside the coating sheet 14. The problem of sunlight reflection due to 14 is avoided, and the amount of received light can be increased.

  Moreover, although the solar cell module 26 is installed outside the covering sheet 14, the solar cell module 26 is not directly installed on the covering sheet 14 but is installed via the resin film 24. Furthermore, in this embodiment, since the edge part of the coating sheet 14 is piled up on the upper surface of the fixing ear | edge part 32 of the resin film 24, when replacing | excluding the coating sheet 14, the resin film 24 (namely, pipe house solar). There is no need to remove the battery sheet 22). Therefore, the influence on the solar cell module 26 can be minimized, and labor and time for replacing the covering sheet 14 can be reduced as compared with the conventional case. Furthermore, when the solar cell module 26 is replaced, it is only necessary to release the locking of the locking member 30 at the replacement portion. As a result, the locking of the covering sheet 14 and the fixing ear 32 of the resin film 24 at the replacement portion is released, and the resin film 24, that is, the solar cell module 26 can be replaced. At this time, the covering sheet 14 is merely unlocked at the replacement portion, and after the replacement resin film 24 is installed, it is locked by the locking member 30 as before the replacement. Therefore, when replacing the solar cell module 26, for example, it is not necessary to perform an operation of removing the covering sheet 14 over the entire surface, and labor and time can be reduced as compared with the conventional case.

  As shown in FIG. 1, in this embodiment, a plurality of resin films 24 are locked in the longitudinal direction, and one solar cell module 26 is bonded to each resin film 24. . Thereby, compared with the case where the some solar cell module 26 is adhere | attached on the resin film 24 extended in the longitudinal direction of one sheet, when the solar cell module 26 replaced | exchanged, the solar cell module 26 replaced | exchanged adheres. It is only necessary to remove the resin film 24, and the problem of having to remove the other solar cell modules 26 together can be avoided.

  On the other hand, a plurality of solar cell modules 26 may be bonded to a single resin film 24 extending in the longitudinal direction. In this case, when the resin film 24 is installed between the pair of locking members 30, 30. Can reduce labor and time. When replacing a certain solar cell module 26, the solar cell module 26 to be replaced and the resin film 24 between the adjacent solar cell modules 26 and 26 are cut, and the solar cell module 26 to be replaced is bonded. By removing the resin film 24, the problem of having to remove the other solar cell modules 26 together can be avoided.

  In addition, as in the present embodiment, the opening area 62 that is not covered with the covering sheet 14 is formed, so that the effective area (necessary amount) of the covering sheet 14 and the cost can be reduced. Moreover, the opening area | region 62 can also be made into the ventilation hole for ventilation by removing the solar cell sheet 22 for pipe houses except at the time of bad weather. In addition, since it is necessary to cover the opening area | region 62 without a clearance gap, the resin film 24 or the several resin film 24 connected by the latching member 30 is made into the shape which can cover the opening area | region 62 completely.

  Furthermore, the locking member 30 employed in the present embodiment is generally commercially available and is easily available (for example, “Vinipet” (registered trademark) manufactured by Toto Kogyo Co., Ltd.). Therefore, it is not necessary to newly manufacture the locking member 30, and the present invention can be implemented by using an existing product. In this embodiment, both the covering sheet 14 and the resin film 24 are locked by one locking member 30, but separate locking members are used for locking the covering sheet 14 and the resin film 24. May be used. In this case, a commercially available locking member can be used as either locking member. Furthermore, in the present embodiment, a plurality of locking members 30 extending in the width direction are adopted between the pair of locking members 30 and 30 extending in the length direction of the pipe house 10. “T joint” or “cross joint” manufactured by Toto Kogyo Co., Ltd. may be adopted. According to such products, the locking member 30 extending in the width direction can be easily installed, and the locking member 30 extending in the length direction can be connected to the locking member 30 extending in the width direction. Become. Therefore, the implementation of the present invention is further facilitated by adopting such a product.

  Furthermore, by providing a bracing member between the raised members 44 on both sides of the top of the arched skeleton 18, the pipe house solar cell sheet 22 can be prevented from bending. In particular, in the present embodiment, the locking member 30 is employed as a member that forms the bracing between the raising members 44 on both sides, and the engagement between the locking members 30 and 30 extending in the width direction of the pipe house 10 is related. Not only the stopping action but also the effect of preventing the bending. In addition, as a member which becomes the bracing between the raising members 44 and 44 on both sides, the member is not limited to the locking member 30 as in the present embodiment, and may be a member having a large bending rigidity. For example, a long member having a small diameter, such as a metal pipe or a solid rod-like member, can be suitably employed, but the cross section is not limited to a circle, and may be a polygon or the like.

  Further, the plurality of raising members 44 of the present embodiment are all of the same shape, and the height of each gantry 45 is made constant so that the solar cell modules 26 are arranged horizontally. Thereby, when the solar cell module 26 is inclined, it is possible to avoid the problem that sunlight does not enter depending on the time zone, and the amount of received light can be increased. However, the horizontal arrangement of the solar cell module 26 is merely an example, and the inclination angle of the solar cell module 26 is information on the point where the pipe house 10 is provided, the direction of the pipe house 10, the season (ie, the altitude of the sun), and the like. Is preferably set in consideration of the above. Further, as described above, the inclination angle can be adjusted by adjusting the length dimension α of the connecting portion 47 and the angle β at the connecting portion between the attaching portion 46 and the attaching side connecting portion 47b. It can also be adjusted by a method such as shifting the fixing position of each raising member 44 provided only on one side across the zenith.

  Furthermore, with respect to the raising member 44 of the present embodiment, the gantry 46 and the mounting part 48 extend to the opposite side with the connecting part 50 interposed therebetween, and they are mutually connected when the bolt is fixed to the groove member 34 and the arched skeleton 18. Therefore, the working efficiency can be increased.

  Furthermore, if the width dimension of the covering sheet 14 covering the roof portion of the pipe house 10 is 2 to 3 m by installing the solar cell sheet 22 for the pipe house by providing the opening region 62, the extension for extending the covering sheet 14 is performed. It is not always necessary to provide a band (for example, “Mica Line” (registered trademark) manufactured by Ishimoto Maolan Co., Ltd.), and the cost can be reduced.

  Next, FIG. 8 shows a pipe house 64 as a second embodiment of the present invention. In the following embodiments, the same members and parts as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and detailed description thereof is omitted.

  The pipe house 64 in this embodiment is covered with the covering sheet 66 over the entire surface, and the opening region 62 is not provided. That is, as shown in FIG. 9, the covering sheet 66 extending from the outside of the pipe skeleton 12 is locked by the elastic pressing member 36, so that the upper side of the side wall portion 40 outside the one groove member 34. Extends along the inner surface of the concave groove 42 and reaches the upper side of the inner side wall 40. Further, it continuously extends to the upper side of the inner side wall portion 40 of the other groove member 34, and then extends along the inner surface of the concave groove 42, from the upper side of the outer side wall portion 40 to the outside of the pipe skeleton 12. It extends. When the covering sheet 66 is replaced in the present embodiment, the replacement covering sheet is locked so as to cover the opening region formed by cutting out the covering sheet to be replaced and cutting the covering sheet. It is only necessary to lock to 30. Thereby, also in this embodiment, the influence which the solar cell sheet 22 for pipe houses, ie, the solar cell module 26, has at the time of replacement | exchange of the coating sheet 66 can be minimized.

  Said 1st embodiment is especially suitable when installing the solar cell sheet 22 for pipe houses which is this invention in the pipe house already covered with the coating sheet. That is, the pipe sheet solar cell sheet 22 is installed so as to cover the opening region 62 while cutting off the covering sheet of the part where the solar cell sheet 22 for pipe house is installed. On the other hand, in this embodiment, it can also be adopted for a pipe house that is not yet covered with a covering sheet, and the work of cutting the installation portion of the pipe house solar cell sheet 22 in the covering sheet 66 can be omitted.

  Furthermore, the raising member 68 which can be employ | adopted by this embodiment is shown by FIG. The raising member 68 is different from the raising member 44 of the first embodiment, and the connecting portion 47 is a single member, and the gantry 45, the attaching portion 46, and the connecting portion 47 are integrated. In addition, after forming these separately, you may integrate by welding etc. Moreover, since only a pair of locking members 30 and 30 are disposed in the pipe house 64, the pedestal portion 45 is provided with only one bolt hole 55a. Further, in the raising member 68, the angle γ (see FIG. 10) between the mounting portion 46 and the connecting portion 47 can be adjusted. FIG. 9 shows a mode in which the mounting portion 46 of the raising member 68 and the arched skeleton 18 are fixed by bolts 57 and nuts 59.

  Such a raising member in which the gantry 45, the attachment portion 46, and the connecting portion 47 are integrated can also be adopted in the first embodiment, and the raising member 44 in the first embodiment is the first. The second embodiment can also be adopted.

  Furthermore, FIG. 11 shows a pipe house 70 extending in the east-west direction to which the solar cell sheet 22 for pipe house can be applied as a third embodiment of the present invention.

  As described above, in consideration of the direction in which the pipe house solar cell sheet 22 is arranged, it is preferable to avoid a certain region from being shaded by the solar cell module 26 for a long time. Thus, as in the first embodiment described above, when the pipe house 10 extends in the north-south direction, it is preferable that the plurality of solar cell modules 26 also extend in the north-south direction. Thus, even when the pipe house 70 extends in the east-west direction, it is preferable that the plurality of solar cell modules 26 extend in the north-south direction. Thereby, with the movement of the sun, the shadow made by the solar cell module 26 also moves, and it can be avoided that a certain region becomes a shadow of the solar cell module 26 for a long time.

  More specifically, in the present embodiment, the solar cell module 26 is installed on the roof portion of the pipe house 70 facing south. In FIG. 11, a plurality of locking members 30 are fixed along the arched skeleton 18 and the connecting skeleton 20 in the longitudinal direction and the width direction of the pipe house 70 on the south side of the roof portion of the pipe house 70. Between these locking members 30, a plurality of solar cell sheets 22 for pipe houses are locked in the south direction, and the solar cell modules 26 bonded to the solar cell sheets 22 for pipe houses are also arranged in the south direction. . As described above, it is preferable that the pipe house solar cell sheet 22 extends in the north-south direction regardless of which direction the pipe house extends. In FIG. 11, the raising member (44, 68) in the above embodiment is not used, and the inclination angle of the solar cell module 26 is set to follow the roof slope of the pipe house 70, but the raising member ( 44, 68) may be used to adjust the inclination angle of the solar cell module 26. In addition, the solar cell sheets 22 for each pipe house are installed at a predetermined distance in the north-south direction and the east-west direction, but this distance can be arbitrarily set and does not necessarily need to be arranged apart. , May be adjacent. Further, FIG. 11 also shows a form in which one solar cell module 26 is bonded to one resin film 24. However, the present invention is not limited to this form, and a plurality of solar cells are attached to one resin film 24. The module 26 may be bonded.

  As mentioned above, although embodiment of this invention was explained in full detail, these are illustration to the last, Comprising: This invention is not limited at all by the specific description in these embodiment.

  For example, in the embodiment, the resin film 24 to which the solar cell module 26 is bonded is made larger than the solar cell module 26 as shown in FIG. 3, and the outer peripheral portion of the resin film 24 is the peripheral portion of the solar cell module 26. However, the shape of the resin film 24 is not limited to this. For example, the shape in which the resin film 24 extends outward from the peripheral edge of the lower surface of the solar cell module 26 may be used. That is, the lower surface of the solar cell module 26 need not be covered with the resin film 24. Further, for example, in the above-described embodiment, a hard iron plate or the like may be adopted in part instead of the soft resin film 24.

  In addition, as shown in FIG. 12, in the embodiment, in order to prevent the solar cell module 26 from being peeled off from the resin film 24 and scattering, a member that holds the solar cell module 26 against the resin film 24 is employed. Also good. Specifically, for example, the house film band 74 is fixed between the saddle-shaped parts 72 and 72 whose ends are bent so as to fit into the concave grooves 42 and 42 of the pair of locking members 30 and 30 extending in the longitudinal direction. Then, the solar cell module 26 may be pressed against the resin film 24 by spreading the house film band 74. In FIG. 12, the installation state of the saddle type component 72 and the house film band 74 on one side of the pair of locking members 30 is shown. The saddle-shaped component 72 is locked to the groove member 34 by the elastic pressing member 36 in the same manner as the resin film 24 and the covering sheet 14 (66). The order in which these are superposed is preferably the resin film 24, the bowl-shaped component 72, and the covering sheet 14 (66) from the bottom. Thereby, when the covering sheet 14 (66) is replaced, the influence of the saddle type component 72 can be minimized. Further, one or a plurality of saddle type parts 72 may be arranged in the longitudinal direction, or one or a plurality of saddle type parts 72 may be arranged in the width direction instead of the longitudinal direction. In particular, by providing a plurality of bowl-shaped parts 72 at the same time on the locking member 30 extending in the longitudinal direction and the width direction, the house film band 74 is stretched in a lattice shape, and an excellent scattering effect of the solar cell module 26 is exhibited. Can be done. The house film band 74 may be in contact with the solar cell module 26 or may be slightly separated.
