Description

  The present invention relates to a solar cell mount, and more particularly to a solar cell mount that can change the inclination angle of a solar cell module.

  Conventionally, in order to generate power efficiently in a solar power generation system, a solar cell base configured to increase the incident light from the sun by changing the inclination angle of the solar cell module according to the solar altitude changing according to the season. Are known.

  As such a thing, there exists a thing comprised by the support | pillar and the support bar, for example. A bracket has a bracket having a pair of side walls at a substantially central position in the length direction of the column, and a plurality of holes having different heights are provided on each side wall of the bracket. Further, a solar cell module is attached to the upper portion of the support column via a rotation mechanism so as to be tiltable.

  In addition, the support bar has an upper end attached to the solar cell module so as to be inclined, a hole is provided in the lower end, and is inserted between the pair of side walls (that is, in the bracket).

  With such a configuration, when the inclination angle of the solar cell module is fixed, the lower end of the support bar is inserted between the pair of side walls, and a plurality of holes provided on the side walls with different heights are provided. A hole provided at an arbitrary height is selected, and the height of the selected hole is combined with the height of the hole provided at the lower end of the support rod, and one bolt is passed through these holes. Then, a support rod is connected to the bracket by screwing a nut into the tip of the bolt to fix the inclination angle of the solar cell module.

  Further, when changing the inclination angle of the solar cell module, the nut is removed and the bolt is extracted, and holes having different heights are selected from among the plurality of holes having different heights provided on the side walls. And the operation | work which connects a support bar to a bracket again like the above is performed (for example, patent document 1).

JP-A-8-170790

  However, according to the solar cell mount proposed in Patent Document 1 described above, it is necessary to provide a configuration such as brackets, bolts, and nuts, which causes a problem of an increase in the number of parts and an increase in cost.

  In addition, the large number of parts for fixing the inclination angle of the solar cell module and the need for a tool for tightening or loosening the bolt each time the inclination angle is changed Each time the inclination angle is changed, it is necessary to remove and attach these parts individually, which causes a problem that work efficiency is lowered.

  The present invention has been made in view of the above circumstances, and provides a solar cell mount that does not require a large number of parts, requires no tools, and can improve work efficiency when changing the inclination angle of the solar cell module. It is intended to do.

  In the solar cell mount according to the present invention, the support bar is bent at a plurality of locations, a part of the support bar passes through a hole (post hole) provided in the column, and the other part is a solar cell module. Since it is configured to pass through a hole (blade hole) provided in the holding blade, which is a member that supports the beam that holds the solar cell, the inclination angle of the solar cell module can be fixed without using a nut or bolt. Furthermore, when changing the inclination angle, the support bar can be removed from the column hole or the support bar can be passed through the column hole by rotating the support bar without using a tool.

  That is, the solar cell mount according to the present invention is provided with a support column provided with a plurality of support column holes having different heights, and a blade hole attached to an upper portion of the support column via a rotation mechanism so as to be tiltable. A holding blade; a support rod arbitrarily selected from the plurality of support holes; and a support rod that spans the blade hole and fixes the holding blade at a predetermined inclination angle. Is substantially perpendicular to the distal end portion and the distal end portion, and substantially perpendicular to the strut hole penetrating portion penetrating one of the strut holes, the strut hole penetrating portion and the distal end portion. A first connecting portion, a blade hole penetrating portion that is substantially perpendicular to the first connecting portion and penetrates the blade hole, and a second connecting portion that is substantially perpendicular to the blade hole penetrating portion. Having, the strut hole penetrating part and the blade hole penetrating Characterized in that it is substantially parallel to the.

  According to the solar cell mount according to the present invention configured as described above, the strut hole penetrating portion and the tip end portion are substantially at right angles, and the strut hole penetrating portion and the first connecting portion are substantially at right angles. Even if it receives, since the front-end | tip part adjacent to a support | pillar hole penetration part or a 1st connection part contacts the surface of a support | pillar, this can prevent that a support | pillar hole penetration part remove | deviates from a support | pillar hole.

  In addition, since the blade hole penetrating portion and the first connecting portion are substantially perpendicular, and the blade hole penetrating portion and the second connecting portion are substantially perpendicular, the second adjacent to the blade hole penetrating portion even when subjected to wind load. Since the first connecting portion or the second connecting portion hits the surface of the holding blade, it is possible to prevent the blade hole penetrating portion from being detached from the blade hole.

  For this reason, it is possible to hold and fix the support bar to the support column and the holding blade independently without using a nut or bolt, so that a large number of parts are not required and the inclination angle of the solar cell module is changed. Work efficiency can be improved.

  Furthermore, in order to change the inclination angle of the holding blade because the strut hole penetrating portion and the blade hole penetrating portion are substantially parallel and the tip portion is substantially perpendicular to the strut hole penetrating portion and the first connecting portion. When the support rod is rotated around the first connecting portion as the rotation axis and the support through-hole and the tip are removed from the support post hole, or when the support post-penetration through and the front end are passed through the support post hole, It is possible to prevent the movement of the support bar from being hindered by the blade hole penetrating portion penetrating the blade.

  Further, in the solar cell mount according to the present invention, the support bar has a handle portion that is substantially perpendicular to the second connecting portion, and the tip portion is bent upward from the horizontal direction, The blade hole penetrating part and the handle part are bent in opposite directions with respect to the second connecting part, and the strut hole penetrating part and the blade hole penetrating part are mutually opposite to the first connecting part. It is preferable to have a configuration bent in the opposite direction.

  According to the solar cell mount according to the present invention configured as described above, the handle hole penetrating portion penetrates the strut hole by providing the handle portion substantially perpendicular to the second connecting portion, and the blade When the hole penetrating portion penetrates the blade hole, the torque of the handle portion in the direction in which the end opposite to the second connecting portion of the end of the handle portion is lowered with the first connecting portion as the rotation axis due to the mass of the handle portion. Will occur.

  Since the blade hole penetrating portion and the handle portion are bent in opposite directions with respect to the second connecting portion, the blade hole penetrating portion has an opposite side (second connecting portion side) to the first connecting portion. Torque works in the direction that the edge goes down.

  In addition, since the strut hole penetrating portion and the blade hole penetrating portion are bent in directions opposite to each other with respect to the first connecting portion, the strut hole penetrating portion has a side opposite to the first connecting portion (tip portion side). Torque works in the direction that the end of the arm goes up.

  As a result, a force acts in the direction in which the upper end of the tip is pressed against the column at the tip bent upward from the horizontal direction, further preventing the column hole penetrating portion from being detached from the column hole. can do.

  Furthermore, in the solar cell mount according to the present invention, the rotation moment due to the mass of the handle portion, the second connection portion, and the blade hole penetration portion when the first connection portion is used as the rotation shaft is the column hole penetration portion and the tip portion. It is preferable that the mass and length of each part are set so as to be larger than the rotational moment due to the mass.

  According to the solar cell gantry according to the present invention configured as described above, the moment in the direction in which the end of the blade hole penetrating portion on the second connecting portion side is lowered, the end on the tip end portion side of the column hole penetrating portion is lowered. Since it becomes larger than the moment of a direction, it can prevent more reliably that a support | pillar hole penetration part remove | deviates from a support | pillar hole.

  In addition, when the front-end | tip part is bent below a horizontal surface, the same effect can be produced by bending a handle | steering-wheel part with respect to a 2nd connection part in the same direction as a blade hole penetration part.

  According to the solar cell mount according to the present invention, a large number of parts are not required, and a working tool can be improved even when the inclination angle of the solar cell module is changed.

It is a side view which shows the state with which the holding blade 2 of the solar cell mount 100 of a present Example was fixed to the inclination angle for summer. It is a side view which shows the state by which the holding blade 2 of the solar cell mount 100 of a present Example was fixed to the inclination angle for winter. It is a perspective view which shows the structure of the support bar 3 of FIG. 1, FIG.

  Hereinafter, the solar cell mount 100 as the best embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a side view showing a state in which the holding blade 2 of the solar cell gantry 100 of the present embodiment is fixed at an inclination angle for summer, and FIG. 2 is a holding blade 2 of the solar cell gantry 100 of the present embodiment. FIG. 3 is a side view showing a state in which is fixed at an inclination angle for winter, and FIG. 3 is a perspective view showing a configuration of the support rod 3 of FIGS. 1 and 2.

  As shown in FIGS. 1 and 2, the solar cell frame 100 of the present embodiment includes a support column 1, a holding blade 2, and a support bar 3.

  The support column 1 is, for example, a U-shaped one, and a lower portion thereof is embedded and fixed in the ground. Moreover, the support | pillar 1 is provided with two support | pillar holes 6 (6a, 6b) from which the height from the ground surface differs (that is, the distance from the pin 4 mentioned later differs), These support | pillar holes 6a, 6b The inner diameter of each is larger than the outer diameter of the support bar 3.

  The holding blade 2 is a member (in this example, having an L-shaped cross section) that supports a plurality of beams 5 (in this example, having a U-shaped cross section) that holds the solar cell module 8. The holding blade 2 is pivotally supported with respect to the column 1 and is attached to the column 1 via a pin (rotating mechanism) 4 provided on the upper side of the column 1 so as to be tiltable. Yes (pin structure). Further, a blade hole 7 is provided in a part of the holding blade 2, and the diameter of the blade hole 7 is larger than the diameter of the support rod 3.

  As shown in FIG. 3, the support bar 3 is formed by bending a single bar having a substantially uniform thickness at a plurality of locations, and includes a tip end portion a, a support hole penetration portion b, and a first connection. It has a portion c, a blade hole penetrating portion d, a second connecting portion e, and a handle portion f.

  The strut hole penetrating part b is substantially perpendicular to the tip part a, the first connecting part c is substantially perpendicular to the strut hole penetrating part b and the tip part a, and the blade hole penetrating part d is the first part. The second connecting portion e is substantially perpendicular to the blade hole penetrating portion d, and the handle portion f is substantially perpendicular to the second connecting portion e.

  In addition, the first connecting portion c and the second connecting portion e are configured such that the second connecting portion e and the second connecting portion e when the support hole penetrating portion b is passed through the support hole 6 and the blade hole penetrating portion d is passed through the blade hole 7. The handle portion f is bent at a predetermined angle so as not to hit the solar cell module 8 or the beam 5.

  Further, the blade hole penetrating part d and the handle part f are bent in opposite directions with respect to the second connecting part e. As described above, since the blade hole penetrating part d and the second connecting part e are substantially perpendicular, and the second connecting part e and the handle part f are substantially perpendicular, the blade hole penetrating part d and the handle part f Is a substantially parallel positional relationship.

  The strut hole penetrating portion b and the blade hole penetrating portion d are bent in directions opposite to each other with respect to the first connecting portion c. As described above, the strut hole penetrating part b and the first connecting part c are substantially perpendicular to each other, and the first connecting part c and the blade hole penetrating part d are substantially perpendicular to each other. The position is substantially parallel to the hole penetrating part d.

  Further, the rotational moment due to the mass of the handle portion f, the second coupling portion e, and the blade hole penetrating portion d with the first coupling portion c as the rotation axis is sufficiently larger than the rotational moment due to the mass of the column hole penetrating portion b and the tip end portion a. The mass and length of each part are set so as to increase.

Next, the operation by the solar cell pedestal 100 will be described separately for [operation when changing the tilt angle] and [normal operation].
[Action when changing the tilt angle]
First, the case where the front-end | tip part a and the support | pillar hole penetration part b are penetrated to the support | pillar hole 6a is demonstrated. The blade hole penetrating portion d of the support rod 3 is previously penetrated into the blade hole 7, and has a handle portion f from this state, and is opposite to the second connecting portion e at the end of the handle portion f as shown in FIG. The support rod 3 is rotated in the rotation direction of the arrow g1 with the first connecting portion c as a rotation axis so that the side end f1 is lifted upward.

  Then, when the support rod 3 is rotated until the inclination of the handle part f becomes substantially vertical, the inclinations of the column hole penetration part b and the blade hole penetration part d, which are substantially parallel to the handle part f, are also substantially vertical. The inclination of the part a is substantially horizontal. Further, the handle portion f is moved up and down to adjust the height of the end a1 of the tip end portion a to the height of the column hole 6a.

  Thereafter, the tip end a is passed through the column hole 6a, and the end f1 of the handle portion f is lowered so that the tilt of the handle portion f becomes substantially horizontal, and the support rod 3 is moved to the arrow with the first connecting portion c as the rotation axis. Rotate in the direction of rotation of g2 (the direction opposite to the arrow g1).

  Thereby, the front-end | tip part a penetrates to the support | pillar hole 6a, and the end a1 of this front-end | tip part a turns upwards rather than a horizontal direction. Further, the support hole penetrating part b whose inclination is substantially horizontal passes through the support hole 6a.

  Next, the case where the front-end | tip part a and the support | pillar hole penetration part b are removed from the support | pillar hole 6a is demonstrated. In this case, the handle bar f having a substantially horizontal inclination is provided, and the support bar 3 is rotated so that the inclination of the handle part f is rotated about 90 degrees with the first coupling part c as a rotation axis, as shown in FIG. Is rotated in the rotation direction of the arrow g1.

  As a result, the inclination of the support hole penetrating part b is rotated by approximately 90 degrees to be disengaged from the support hole 6a, and the tip part a whose inclination is substantially horizontal is removed from the support hole 6a.

  The above-described action is not limited to the case where the tip end portion a and the column hole penetration portion b are penetrated to the column hole 6a or the case where the tip portion a and the column hole penetration portion b are removed. The same applies to the case of removing them from the column holes 6b.

  In addition, when the tip part a is substantially right-angled with the support | pillar hole penetration part b and the 1st connection part c, when displacing (rotating) the support rod 3 by using the 1st connection part c as a rotating shaft, the support | pillar before rotating. The distance between the hole 6 and the blade hole 7 (the distance between the strut hole penetrating portion b and the blade hole penetrating portion d), and the distance between the strut hole 6 and the blade hole 7 after being rotated approximately 90 degrees. Since there is little difference (distance between the end a1 of the tip end a and the blade hole penetrating portion d) (the change in the distance is small), the tip end a and the strut hole penetrating portion b penetrate the strut holes 6a and 6b. When removing the tip part a and the column hole penetrating part b from the column holes 6a and 6b, the movement of the support rod 3 is prevented even if the blade hole penetrating part d is previously penetrated through the blade hole 7. This can be prevented (can be detached without increasing the displacement of the support bar 3).

  Further, when the blade hole 7 is provided on the south side of the pin 4 (north side in the southern hemisphere), in the summer, as shown in FIG. 1, the tip end portion a and the support hole penetration portion b are penetrated through the support hole 6a. The inclination angle of the solar cell module 8 with respect to the horizontal is reduced, and in winter, the inclination of the solar cell module 3 with respect to the horizontal is made by penetrating the tip end portion a and the column hole penetration portion b through the column hole 6b as shown in FIG. It is preferable to increase the angle.

In this embodiment, the column holes 6 are provided at two places having different heights. However, the positions at which the column holes 6 are provided are not limited to two places, and are provided at three or more places having different heights. For example, it is possible to provide a support hole 6c (not shown) for spring and autumn between the support hole 6a and the support hole 6b.
[Normal operation]
Since the strut hole penetrating portion b and the blade hole penetrating portion d are substantially perpendicular to the first connecting portion c and parallel to each other, the tension or compression force applied to the support rod 3 is applied to the strut hole penetrating portion b. And the blade hole penetrating part d can be received vertically, and the inclination angle of the holding blade 2 can be reliably held.

  Further, the strut hole penetrating part b penetrates the strut hole 6 (either 6a or the strut hole 6b), the blade hole penetrating part d penetrates the blade hole 7, and the inclination angle of the holding blade 2 is fixed. In the state (normal time), the strut hole penetrating portion b and the tip end portion a having a substantially horizontal inclination angle are substantially perpendicular, and the strut hole penetrating portion b and the first connecting portion c are substantially perpendicular. The movement of the column hole penetrating part b in the direction away from the column hole 6 is restricted.

  In addition, since the blade hole penetrating portion d and the first connecting portion c whose inclination angle is substantially horizontal are substantially perpendicular, and the blade hole penetrating portion d and the second connecting portion e are substantially perpendicular, the blade hole The movement of the penetrating part d in the direction away from the blade hole 7 is restricted.

  Further, as shown in FIG. 3, in a normal state, the torque g2 is generated in the direction in which the end f1 of the handle portion f is lowered with the first connecting portion c as the rotation axis due to the mass of the handle portion f. The torque g2 causes a torque to act on the blade hole penetrating portion d in a direction in which the end opposite to the first connecting portion c (the second connecting portion e side) is lowered, and the strut hole penetrating portion b has the first connecting portion. Torque acts in the direction in which the end opposite to the portion c (the tip end a side) rises.

  A direction in which the end (upper end) a1 of the tip end a is pressed against the support column 1 (the direction from the front to the back in FIGS. 1 and 2) is applied to the tip end a bent upward from the horizontal direction. ) To prevent the tip portion a and the column hole penetrating portion b from being detached from the column hole 6.

  In particular, the rotational moment due to the mass of the handle portion f, the second coupling portion e, and the blade hole penetrating portion d is sufficiently larger than the rotational moment due to the mass of the column hole penetrating portion b and the tip end portion a with the first coupling portion c as the rotation axis. By setting it to be larger, the moment in the direction in which the end of the blade through hole d on the second connecting portion e side is lowered (the rotation center is the first connecting portion c) is the tip end portion a of the strut hole penetrating portion b. The moment in the direction in which the side end is lowered is surely increased, and it is possible to more reliably prevent the distal end portion a and the column hole through portion b from being detached from the column hole 6.

  According to the solar cell gantry 100 according to the present embodiment configured as described above, the support hole penetration part b and the tip end part a are substantially perpendicular, and the support hole penetration part b and the first connecting part c are substantially orthogonal. Therefore, even if the wind load is received, since the tip end a or the first connecting portion c adjacent to the support hole penetrating part b hits the surface of the support pillar 1, the support hole penetrating part b can be easily moved from the support hole 6 to one side. It is possible to prevent slipping, and thus it is possible to prevent the column hole penetrating part b from being detached from the column hole 6.

  Further, since the blade hole penetrating portion d and the first connecting portion c are substantially perpendicular, and the blade hole penetrating portion d and the second connecting portion e are substantially perpendicular, the blade hole penetrating portion even when subjected to wind load. Since the first connecting part c or the second connecting part e adjacent to d hits the surface of the holding blade 2, it is possible to prevent the blade hole penetrating part d from easily sliding to one side from the blade hole 7, It is possible to prevent the blade hole penetrating portion d from being detached from the blade hole 7.

  For this reason, it is possible to hold and fix the support bar 3 independently to the support column 1 and the holding blade 2 without using nuts and bolts, without requiring a large number of parts and without using a tool, the inclination angle can be increased. Since it becomes possible to change, the work efficiency at the time of changing the inclination-angle of the solar cell module 8 can be improved.

  Furthermore, since the tip part a is substantially perpendicular to the support hole penetration part b and the first connection part c, when the support bar 3 is displaced with the first connection part c as the rotation axis, the support hole penetration part b and the tip part When the distance between the part a and the blade hole penetrating part d is small and the tip part a and the pillar penetrating part b are removed from the pillar hole 6 or when the tip part a and the pillar hole penetrating part b are passed through the pillar hole 6 In addition, even if the blade hole penetrating portion d is penetrated through the blade hole 7 in advance, the movement of the support rod 3 can be prevented from being hindered.

  Further, according to the solar cell gantry 100 according to the present embodiment configured as described above, the torque is generated in the direction in which the end f1 of the handle portion f is lowered with the first connecting portion c as the rotation axis due to the mass of the handle portion f. For this reason, a force acts in the direction in which the upper end a1 of the distal end a is pressed against the support column 1 at the distal end a bent upward from the horizontal direction, and the support hole through portion b is detached from the support hole 6. Can be further prevented.

  Furthermore, according to the solar cell gantry 100 according to the present example configured as described above, the mass of the handle part f, the second connection part e, and the blade hole penetrating part d when the first connection part c is a rotation shaft. By making the rotation moment due to the column sufficiently larger than the rotation moment due to the mass of the column hole penetration part b and the tip end part a, it is possible to more reliably prevent the column hole penetration part b from being detached from the column hole 6. Can do.

  In addition, the solar cell mount according to the present invention is not limited to the above-described form. For example, when the tip end portion a is bent downward from the horizontal plane, the handle portion f is bladed with respect to the second connection portion e. Any structure may be used as long as a large moment is generated in the direction in which the end a1 of the tip end portion a is pressed against the column 1 by bending in the same direction as the hole penetrating portion d.

  Further, the same function can be realized by replacing the roles of the holding blade hole and the support hole, making the support hole one, making a plurality of holding blade holes, and inserting the support rods in reverse.

  As mentioned above, although the solar cell stand of this invention has been demonstrated based on the Example, about a concrete structure, it is not restricted to a present Example.
