Description

  The present invention relates to a solar power generation module installation structure that is applied when a solar power generation module is installed on a tension member stretched between two different points.

  Biomass, wind power generation, geothermal power generation, fuel cells, solar power generation, etc. have been developed as alternative energy alternatives to fossil fuels and nuclear power, but solar power generation has been developed for thermal power generation and nuclear power generation from the viewpoint of low energy density. Although it does not reach, there are few restrictions on the installation location, and there is an advantage that it can be easily installed in a place where electric power is required.

  Photovoltaic power generation equipment is composed of devices such as a solar power generation module that converts sunlight into electric power and a power conditioner that converts direct current power from the solar power generation module into alternating current, but recently, it has been replaced with a power conditioner. The number of cases where an AC conversion device called a micro inverter is attached to each photovoltaic power generation module is increasing, and further expansion of the installation location and accompanying promotion are expected.

  Here, the solar power generation module is installed on the rooftop or ground surface of the building via a gantry, but when designing the gantry, take into account the wind load and other factors, including the weight of the solar power generation module. The material, cross-sectional dimensions, etc. are determined.

  On the other hand, a proposal has been made to attach a solar power generation module to a cable spanned between columns instead of the ground or the roof of a building and suspend it on the cable (Patent Document 1).

Japanese Patent Laying-Open No. 2015-37163

  When the solar power generation module is installed in the form of being suspended on the cable as described above, it is not necessary to secure the ground or the rooftop of the building as an installation surface as in the past, but it is advantageous in terms of space utilization, Measures must be taken to prevent the occurrence of damage to the photovoltaic module or breakage of the cable due to wind loads.

  However, in the past, it has not been said that sufficient wind countermeasures have been taken, and the occurrence of a situation such as damage to the photovoltaic module due to wind, or breakage of the cable or wire holding the photovoltaic module. There was concern.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a solar power generation module installation structure that can sufficiently enhance safety and strength against wind.

In order to achieve the above object, the solar power generation module installation structure according to the present invention has a structure in which a solar power generation module formed in a plate shape is stretched between two different points as described in claim 1. In the installation structure of the solar power generation module arranged on the tensile material so that the material axis and the plate surface of the material are substantially parallel,
The solar power generation module is connected to the tension member such that the solar power generation module is rotatable about the material axis of the tension member, and the center of gravity including the solar power generation module is positioned at the tension member. The weight is installed on the photovoltaic module so as to be lower than the fulcrum position of the photovoltaic module by
When the wind is from a direction that is not perpendicular to the plate surface of the photovoltaic power generation module and receives a component that is parallel to the plate surface and perpendicular to the axis of the tensile material, the acting load is applied to the tensile material. In the photovoltaic power generation module, wind load resistance means are respectively provided at two portions sandwiching the tensile material so as to be larger in the direction away from the tensile material than in the direction of going.

  Moreover, the installation structure of the photovoltaic power generation module according to the present invention is characterized in that each wind load resistance means includes a curved resistance member having a C-shaped cross section, and the photovoltaic power generation so that the open side faces the tensile material side. It is arranged at the edge of the module.

  Further, the solar power generation module installation structure according to the present invention is such that each wind load resistance means is inclined from the vertical position with respect to the plate surface of the solar power generation module toward the tensile material. It is composed of a pair of flat resistor members attached to each surface of the module.

  Further, the installation structure of the photovoltaic power generation module according to the present invention is characterized in that each wind load resistance means has the plate surface when the angle is based on the angle from the angle extending parallel to the plate surface on the tensile material side. It is composed of a pair of movable flat resistor members attached to the respective surfaces of the photovoltaic power generation module so as to be rotatable within a range up to an angle of less than 180 °.

  In the installation structure of the photovoltaic power generation module according to the present invention, the upper limit of the angle range is an angle larger than 90 ° with respect to the plate surface.

  In the installation structure of the solar power generation module according to the present invention, when the plate-shaped solar power generation module is arranged on the tensile material, the solar power generation module is configured to be rotatable around the material axis of the tensile material. The solar power generation module is connected to the tensile material and the weight is installed on the solar power generation module so that the center of gravity position including the solar power generation module is lower than the fulcrum position of the solar power generation module by the tensile material. When the wind is from a direction that is not perpendicular to the plate surface and is parallel to the plate surface and perpendicular to the material axis of the tensile material, the working load is from the tensile material in the direction toward the tensile material. Wind load resistance means are respectively provided in two portions of the photovoltaic power generation module sandwiching the tensile material so as to increase in the direction of moving away.

  In this way, when there is no wind, the solar power generation module is balanced at a predetermined angular position with respect to the axis of the tensile material by the action of the weight installed in the solar power generation module, and in that state Hold.

  On the other hand, when a constant wind blows and a wind of a component parallel to the plate surface of the photovoltaic power generation module and perpendicular to the material axis of the tensile material acts on the wind load resistance means provided at the two parts, Since each wind load resistance means is configured such that the acting load is larger in the direction away from the tensile material than in the direction toward the tensile material, more wind load acts on the wind load resistance means located on the leeward side. .

  Therefore, the photovoltaic power generation module rotates in a direction in which the wind load resistance means located on the leeward side moves to the side closer to the leeward side, and as a result, in a direction parallel to the wind direction when the angle is attached Head for.

  Therefore, the wind load acting on the photovoltaic power generation module is reduced, and the tensile force generated in the tensile material is also reduced accordingly, thus the design conditions of the photovoltaic power generation module and the tensile material against the wind load are eased, and the photovoltaic power generation module The installation cost can be greatly reduced.

  The solar power generation module is also called a solar cell panel or a solar cell module, and a commercially available one can be used as appropriate, and a rectangular plate is a typical example.

  The tensile material includes a member called a cable, a wire, or the like. Moreover, a tension | tensile_strength material can be comprised with arbitrary materials, for example, can be comprised with a wire from PC steel wire or PC steel. The tensioning direction of the tensile material does not necessarily have to be horizontal, and may be a state in which a deflection is formed between two points.

  How to form the two points where the tensile material is stretched is arbitrary, for example, it can be set as the apexes of two tower-like structures that are spaced apart from each other, and sandwiches a river or valley 2 It can also be the summit or hillside of two mountains.

  As long as the weight functions as a gravity balancer and is installed in the photovoltaic module so that the position of the center of gravity including the photovoltaic module is lower than the fulcrum position of the photovoltaic module by the tensile material, Although the specific configuration is arbitrary, it is desirable to have a configuration that is not affected by the wind as much as possible and has high posture stability. For example, it is formed of a metal material having a high mass density, and a photovoltaic power generation module through a truss material It is possible to employ a configuration that is suspended below the sway.

  It is desirable to install the weight on the solar power generation module so that the attitude of the solar power generation module at no wind is at an arbitrary angle (elevation angle). According to such a configuration, the power generation efficiency is improved in consideration of the solar altitude. Can be achieved.

  In the present invention, wind that blows perpendicularly to the plate surface of the photovoltaic power generation module is out of scope, but it is not necessary to assume a situation where such wind continues to blow for a long time. Don't be.

  In addition, the wind load resistance means of the present invention maintains its action even when the wind direction is reversed and the windward and leeward are switched, or the wind from diagonally upward is changed to the wind from diagonally downward. Therefore, it is necessary to have a symmetrical structure with a tensile material as the center or a structure close to it, and a vertically symmetrical structure with the plate surface of the photovoltaic power module as the center or a structure close to it. Therefore, the wind load component perpendicular to the plate surface of the solar power generation module cancels out on both sides of the tensile material and does not affect the rotation of the solar power generation module. In the first place, it does not contribute to the rotation of the photovoltaic module.

  Therefore, it is sufficient for the wind load resistance means to consider only a component parallel to the plate surface of the photovoltaic power generation module and perpendicular to the material axis of the tensile material.

  As long as the wind load resistance means is configured so that the applied load is larger in the direction away from the tensile material than in the direction toward the tensile material, the specific configuration thereof is arbitrary, for example, the curved shape of the C-shaped cross section. The resistance member can be arranged at the edge of the photovoltaic module so that the open side faces the tension material side, and the resistance member is inclined from the vertical position to the plate surface of the photovoltaic module to the tension material side. It is also possible to form a pair of flat resistance members respectively arranged on each surface of the photovoltaic power generation module.

  Further, the photovoltaic power generation is such that it can rotate within a range from an angle extending parallel to the plate surface on the side of the tensile material to an angle that is less than 180 ° with respect to the plate surface when the angle is used as a reference. It is also possible to configure with a pair of movable flat plate resistance members attached to each surface of the module. According to such a configuration, the wind load acting on the wind load resistance means on the windward side is substantially zero. Therefore, it becomes easy to match the attitude of the photovoltaic power generation module with the wind direction.

  In particular, if the upper limit of the above-mentioned angle range is set to an angle larger than 90 ° with respect to the plate surface, it is possible to avoid an excessive load acting on the wind load resistance means on the leeward side. It is possible to prevent damage to the means.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a solar power generation module installation structure according to the present invention will be described with reference to the accompanying drawings.

  Fig.1 (a) is the whole side view which showed the installation structure 1 of the solar power generation module which concerns on this embodiment. As can be seen from the figure, the installation structure 1 of the photovoltaic power generation module has a cable 3 as a tensile material stretched between the tops of the tower-like structures 2 and 2 erected between two different points. Are fixed to the ground 5 via anchors 4 and 4, and a plurality of photovoltaic power generation modules 6 are arranged on the cable so as to form a line along the cable 3.

  The photovoltaic power generation module 6 stands on the tower-like structures 2 and 2 with, for example, rivers and valleys sandwiched between them, and the cables 3 are stretched across the rivers and valleys so that the upper spaces of the rivers and valleys It can be used effectively as an installation space.

  What is necessary is just to use suitably what is marketed by names, such as a solar power generation module, a solar cell panel, a solar cell module, as a solar power generation module.

  Although the cable 3 depends on the total weight including the plurality of solar power generation modules 6, it is possible to ensure a necessary tensile strength with a margin by configuring the cable 3 with a PC steel wire, for example.

  As shown in FIG. 2B, the photovoltaic power generation module 6 has a rectangular plate shape as a whole, and is rotatable around the material axis of the cable 3 so that the material axis of the cable 3 is substantially parallel to the plate surface. Are connected to the cable so as to be, and two edges that are parallel to the material axis of the cable 3 and sandwich the cable, in the figure, two short side edges are two parts of the present invention, Curved resistance members 7 as wind load resistance means are attached to the respective short side edges.

  On the other hand, a weight 9 is suspended below the solar power generation module 6 via a truss member 8.

  As shown in FIG. 2 (a), the weight 9 is appropriately set so that its center of gravity G including the solar power generation module 6 is lower than the fulcrum position R of the solar power generation module by the cable 3. Thus, the photovoltaic power generation module 6 can be balanced at a predetermined angular position along the axis of the cable 3 and the posture can be maintained.

  It is desirable that the weight 9 is not affected by the wind as much as possible and has a high posture stability. For example, the weight 9 may be made of a metal material having a high mass density.

  As shown in FIG. 2B, a base plate 22 with a sleeve 21 welded thereto is attached to the lower surface of the photovoltaic power generation module 6, and the cable 3 is inserted into the sleeve and connected to the cable. Accordingly, the photovoltaic power generation module 6 can be rotated around the material axis of the cable 3.

  As shown in FIG. 1B, the sleeve 21 extends slightly beyond the long side edge of the photovoltaic power generation module 6 so that the adjacent photovoltaic power generation modules 6 and 6 can rotate. They do not interfere with each other.

  As shown in FIGS. 1 and 2, the curved resistance member 7 has a C-shaped cross section and is disposed in the photovoltaic power generation module 6 so that the open side faces the cable 3 side. As shown in FIG. 3, the resistance member 7 is wind from a direction that is not perpendicular to the plate surface of the photovoltaic power generation module 6, and has a component that is parallel to the plate surface and perpendicular to the material axis of the cable 3. When the load is applied, the working load is larger in the direction away from the cable (thin solid arrow drawn in (b)) than in the direction toward the cable 3 (thin solid arrow drawn in (a)). In FIGS. 4A and 4B, the length of the thick arrow is shown.

  Here, among the thick arrows in FIG. 7 (b), the arrows indicated by solid lines indicate the action direction and action position of the wind load caused by the wind blown obliquely from the upper right to the photovoltaic power generation module 6 by broken lines. The arrows indicate the action direction and the action position of the wind load due to the wind blown obliquely from the lower right on the photovoltaic power generation module 6.

  The curved resistance member 7 can be attached by any method such as extending a mounting arm (not shown) from each short side edge of the photovoltaic power generation module 6 in a direction parallel to the plate surface and fixing it to the tip thereof. However, the wind blown from the oblique direction to the photovoltaic power generation module 6 is surely applied to the portion of the curved resistance member 7 protruding from the blowing side. In order to act, in other words, so as not to act on the part projecting on the opposite side, as shown in FIG. It is desirable to provide the member 31.

  In the solar power generation module installation structure 1 according to the present embodiment, when the solar power generation module 6 is disposed on the cable 3, the solar power generation module is rotatable about the material axis of the cable 3. While connecting to the cable, the weight 9 is installed on the photovoltaic module 6 so that the center of gravity G including the photovoltaic module 6 is lower than the fulcrum position R of the photovoltaic module by the cable 3. When the component receives wind from a direction that is not perpendicular to the plate surface of the photovoltaic module 6 and is parallel to the plate surface and perpendicular to the material axis of the cable 3, the acting load is directed to the cable 3. A curved resistance member 7 is provided on each short side edge portion of the photovoltaic power generation module 6 so as to be larger in the direction away from the cable than the direction.

  In this way, when there is no wind, the solar power generation module 6 is balanced at a predetermined angular position with respect to the material axis of the cable 3 by the action of the weight 9 installed in the solar power generation module 6. Hold the posture in the state (see FIG. 2 (a)).

  On the other hand, when a constant wind blows and winds of components that are parallel to the plate surface of the photovoltaic power generation module 6 and perpendicular to the material axis of the cable 3 act on the curved resistance members 7 and 7, respectively, Since the resistance member is configured so that the acting load is larger in the direction away from the cable 3 than in the direction toward the cable 3, as shown in FIG. 4A, the curved resistance member 7 positioned on the leeward side, In the figure, a large wind load acts on the curved resistance member 7 on the right side.

  In the case of wind blowing obliquely from the lower left to the photovoltaic power generation module 6 as shown in the same figure, the wind load of the component parallel to the plate surface of the photovoltaic power generation module is the downward projecting portion of the curved resistance member 7 Since the acting position is separated from the fulcrum position R by the eccentric distance e, the rotational moment in the direction of the arrow acts on the photovoltaic power generation module 6, and the photovoltaic power generation module 6 is shown in FIG. As shown, the curved resistance member 7 located on the leeward side, the curved resistance member 7 located on the right side in the figure, rotates in a direction to move closer to the leeward side, resulting in an angle. If so, head to the direction parallel to the wind direction.

  The attitude of the photovoltaic power generation module 6 at this time is determined in consideration of the weight 9, and as the weight 9 becomes heavier and the gravity center position G lowers, the attitude change rate by the curved resistance member 7 becomes smaller. Since the degree of reduction of the wind load is reduced, it is desirable to determine the configuration of the weight 9 so that the wind load is reduced as much as possible in consideration of a stable posture in a windless state.

  As described above, according to the solar power generation module installation structure 1 according to the present embodiment, the solar power generation module 6 rotates and moves in a direction parallel to the wind direction by the action of the curved resistance member 7. The wind load acting on the solar power generation module 6 is reduced, and the tensile force generated in the cable 3 is also reduced accordingly, and thus the design conditions of the solar power generation module 6 and the cable 3 with respect to the wind load are relaxed, and the solar power generation The installation cost of the module 6 can be greatly reduced.

  Further, since the tensile force generated in the cable 3 is reduced, the distance between the two points where the cable is stretched can be increased, and the installation of the solar power generation module 6 across the river and valley is easier to realize. Become.

  Although not particularly mentioned in the present embodiment, the attitude of the photovoltaic power generation module 6 when there is no wind is adjusted to an arbitrary angle (elevation angle) by adjusting the length of the truss member 8 as shown in FIG. It is possible to improve the power generation efficiency in consideration of the solar altitude.

  In the present embodiment, the cable 3 is configured to be inserted into the sleeve 21. However, when the sleeve 21 is configured by, for example, a combination of semi-cylindrical members, the photovoltaic power generation module 3 is removed from the cable 3, and thus Maintenance and inspection of the solar power generation module is facilitated.

  Moreover, in this embodiment, although the wind load resistance means of this invention was comprised by the curved-shaped resistance member 7, it replaced with this and is attached to the plate | board surface of the photovoltaic power generation module 6 back to back as shown in FIG. You may comprise by a pair of flat resistance members 61 and 61 which become.

  The plate-like resistance members 61, 61 are attached back to back on each surface of the photovoltaic module in such a manner that they are inclined to the cable 3 side from a position perpendicular to the plate surface of the photovoltaic module 6. Is substantially the same as the above-described embodiment, and the description thereof is omitted here. Also in this modified example, the weight 9 and the truss member 8 need to be arranged in the same manner as in the above-described embodiment, but these are omitted from FIG. 6 for convenience.

  Further, the wind load resistance means of the present invention can be rotated with respect to the plate surface of the solar power generation module 6 as shown in FIG. 7A instead of the curved resistance member 7. You may comprise by a pair of movable flat resistance members 71 and 71 each attached to each surface of the photovoltaic module.

  Here, a stopper 72 is attached to each short side edge of the solar power generation module 6, and the rotation range of the movable flat plate-like resistance member 71 is set to the plate surface of the solar power generation module 6 on the cable 3 side. The angle extending in parallel is limited to a range of approximately 90 ° with respect to the plate surface when the angle is used as a reference.

  When the wind shown in FIG. 7 (b) blows in such a configuration, the movable plate-like resistance members 71, 71 on the windward side, on the left side in the figure, are parallel to the plate surface of the photovoltaic power generation module 6 and the material axis of the cable 3 Since the wind component is perpendicular to the cable 3 and falls to the cable 3 side and becomes parallel to the plate surface, the wind load hardly acts.

  On the other hand, the movable plate-like resistance members 71, 71 on the leeward side, on the right side in FIG. Since the wind load acts at the angular position and the wind acting position is separated from the fulcrum position R by the eccentric distance e, the rotational moment in the arrow direction in FIG. Acts on the photovoltaic power generation module 6, and in the photovoltaic power generation module 6, the movable flat plate-like resistance member 71 located on the leeward side moves to the side closer to the leeward side, as shown in FIG. As a result, it turns in the direction parallel to the wind direction when it is angled.

  Therefore, in addition to the same effects as those of the above-described embodiment, the wind load acting on the movable plate-like resistance members 71 and 71 on the windward side is substantially zero. It becomes easy to match.

  In particular, by adjusting the stopper 72, the upper limit of the above-mentioned angle range is set to an angle larger than 90 ° with respect to the plate surface of the photovoltaic power generation module 6, for example, about 120 ° as shown in FIG. If this is done, the wind load acting on the movable flat plate-like resistance member 81 on the leeward side can be reduced as shown in FIG. 5B, so that the movable flat plate-like resistance member can be prevented from being damaged in advance. It becomes possible.

  Here, the attitude of the photovoltaic power generation module 6 at this time is determined by the balance with the weight 9 as described in the above-described embodiment, and as the weight 9 becomes heavier and the gravity center position G falls, the movable plate Since the posture change rate by the resistance members 81 and 81 is reduced and the reduction degree of the wind load is reduced, the configuration of the weight 9 is determined so that the wind load is reduced as much as possible while considering the stable posture in the no-wind state. It is desirable to do.

  In the above-described modification, the movable flat plate resistance members 71 and 71 and the movable flat plate resistance members 81 and 81 are undulated independently on each surface of the photovoltaic power generation module 6. Thus, the movable plate-like resistance member 71 is configured so that the undulation operation of the movable plate-like resistance members 71 and 71 is interlocked on both surfaces of the photovoltaic power generation module 6, or the undulation operation of the movable plate-like resistance members 81 and 81 You may comprise this movable flat resistance member so that it may interlock | cooperate with both surfaces of the photovoltaic module 6. FIG.

  In the case where the undulation operation of the movable plate-like resistance members 71, 71 and the movable plate-like resistance members 81, 81 is performed independently on each surface of the photovoltaic power generation module 6, the fluctuation of the wind direction, that is, FIG. Speaking in FIG. 8, the movable flat plate-like resistance member 71 or the movable flat plate on the side that is newly subjected to wind pressure with respect to small fluctuations in the wind direction such as blowing up from the lower left of the photovoltaic power generation module 6 or blowing down from the upper left of the diagonal. Although there is a concern that the standing operation of the resistance member 81 is delayed, if the above-described interlocking configuration is used, on the windward side, the movable flat plate resistance members 71 and 71 and the movable flat plate resistance members 81 and 81 are provided on both sides of the photovoltaic power generation module 6. Is always lying on the leeward side and is always standing on both sides of the leeward side, so there is no need to worry about a delay in operation due to fluctuations in the wind direction.

  In these modified examples, it is necessary to dispose the weight 9 and the truss member 8 in the same manner as in the above-described embodiment. However, for the sake of convenience, these are omitted from FIGS.
