Description

  The present invention relates to a solar panel mounting device capable of mounting a solar panel on a mounting base with one touch without using any bolts.

  The solar panel support device has a configuration in which a plurality of solar panels are continuously arranged and supported with respect to the installation base along both the tilt direction and the horizontal direction orthogonal to the tilt direction. . The erection base is formed by assembling a support member disposed in the inclination direction of the solar panel or in the lateral direction, and a column member erected perpendicularly to the ground. A solar panel is supported (Patent Document 1).

  However, also in other prior arts including Patent Document 1, most of the bolts are used to attach the solar panel to the mounting part of the installation base, and a large amount of bolts is required. However, since it takes time to tighten the bolts during construction, there is also a problem that the construction period becomes long after all.

  For example, in order to output 1 MW (megawatt) by solar power generation, 4,000 solar panels having an output of 250 W per sheet are required, and (4,000 × 4 = 16,000) bolts are required. At the same time, about 40 man-hours are required only for the bolting operation, and the number of bolts and the amount of effort required for bolting can be understood.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

  First, with reference to FIG. 1 thru | or FIG. 5, the structure of the installation stand V for attaching and supporting many solar panels P is demonstrated easily. In the following description, the “solar panel device” refers to a state in which a large number of solar panels P are attached to the installation base V along both the tilt direction Q and the lateral direction R. The illustrated solar panel device has a structure in which four and three solar panels P are arranged along an inclination direction Q and a lateral direction R that is a horizontal direction orthogonal to the inclination direction Q, respectively. The erection base V has three types of support members 101a and 101b, each of which is made of a single pipe and having different lengths (heights), an inclined member 102 arranged along the inclination direction Q, and a mounting member 103 for mounting the solar panel. Each member is constructed integrally through a coupling clamp tool 104. The coupling clamp 104 is a clamp used to connect two single pipes orthogonal to each other, and has a structure in which the two clamps are integrated. The column members 101a and 101b are erected perpendicularly to the ground G at portions close to both ends along the inclination direction Q of the solar panel P, and on one side of the column members 101a and 101b, the inclined member 102 is provided. Are arranged at an inclination angle (θ) and are connected together through a coupling clamp 104. The inclined members 102 are arranged at a constant interval (an interval equal to the dimension along the lateral direction R of the solar panel P) by the number of solar panels P along the lateral direction R.

  The inclined member 102 has a length that is approximately an integral multiple of the dimension in the short direction of the solar panel P (approximately four times in the embodiment) (exactly an integer of the dimension in the short direction of the solar panel P). Has a length slightly longer than double). Each of the slanted upper end and the slanted lower end of each of a plurality (four in the embodiment) of each sloping member 102 arranged along the sloping direction Q, and three equal dividing points obtained by dividing the slanting member 102 into four equal parts. The attachment member 103 is integrally connected to the total of the five parts along the lateral direction R via the coupling clamp tool 104. As will be described later, the mounting member 103 made of a single tube is a member to which the solar panel P is mounted via the clamp tool C. Therefore, as shown in FIGS. 2 and 4, the mounting member 103 is an inclined member. The structure is arranged above 102 and does not interfere with the inclined member 102 when the solar panel P is attached.

Next, a solar panel mounting device D ₁ for mounting the solar panel P to the installation base V without using any bolt will be described with reference to FIGS. The solar panel P is formed in a rectangular disk shape by assembling a metal plate. As shown in FIG. 10, a rectangular power generation cell 91 is incorporated at the upper end in the thickness direction. The upper surface of the power generation cell 91 is covered with tempered glass 92, and the lower surface (back surface) of the power generation cell 91 is covered with a back sheet (protective sheet) [not shown]. As a result, the solar panel P having a rectangular disk shape is inclined and arranged so that the short sides thereof are inclined, and the short side portions that are both ends in the longitudinal direction are formed in a reinforcing portion 93 having a hollow rectangular cross section. Is provided over almost the entire height, and the short side portion of the solar panel P is reinforced (see FIGS. 6 and 12). Insertion locking plate portions 1 are integrally formed over the entire length in the longitudinal direction at both ends of the solar panel P in the short direction and at the lower end along the thickness direction. That is, the insertion locking plate portion 1 is formed in an L-shaped cross section with the side plate portion 2 integrally connected to one end portion in the width direction, and the insertion locking plate portion 1 in the longitudinal direction of the insertion locking plate portion 1 is formed. Since both end portions are integrated with the reinforcing portion 93 by welding or the like inside each reinforcing portion 93, the insertion locking plate portion 1 itself is plate-shaped, but one end in the width direction thereof. The portions are formed integrally with the side plate portion 2 and both end portions in the longitudinal direction thereof are integrated with the reinforcing portion 93, so that the rigidity against deformation of the insertion locking plate portion 1 is high.

In the solar panel mounting device D ₁ of the first embodiment, the clamp tool C clamped to the mounting member 103 made of a single tube and the clamp tool C clamped to the mounting member 103 on the upper surface side of the clamp tool C. , And an insertion locking tool E ₁ that is rotatable about an axis along the lateral direction R. The clamp tool C includes a pair of divided bodies 11 and 12 that can clamp the mounting member 103 made of a single pipe from the outside, and each of the divided bodies 11 and 12 is arranged in the circumferential direction of the mounting member 103 made of a single pipe. Flange plate portions 11b and 12b are integrally provided at both ends in the width direction of the peripheral plate portions 11a and 12a inwardly, and one end portion along the circumferential direction of each flange plate portion 11b and 12b is connected. By being connected via the pin 13, the pair of divided bodies 11 and 12 opens and closes around the portion of the connecting pin 13, and enters the inside from the opening 14 provided in the portion facing the connecting pin 13. A single tube constituting the attachment member 103 can be inserted.

  Here, the upper surface side of the peripheral plate portion 11a of the divided body 11 is a portion on which a slide allowing tool 24 described later having a planar shape is disposed. In addition, the width of the flange plate portion 12b of the lower divided body 12 is narrow, and when the clamp tool C is clamped to the single pipe constituting the mounting member 103 at the inner end portion of the flange plate portion 12b, A support plate portion 11d that is in pressure contact with the outer peripheral surface of the single pipe that constitutes the attachment member 103 is formed substantially parallel to the peripheral plate portion 12a. Each of the openings 14 of the divided bodies 11 and 12 protrudes in the radial direction, and the protruding portion 11 c of the divided body 11 disposed above is a short cylinder provided at the base end of the fixing bolt 15. The both ends of the insertion pin 16 inserted in the part 15a are supported. On the other hand, the protruding portion 12c of the divided body 12 disposed below has a bolt insertion groove into which a fixing bolt 15 whose base end portion is rotatably connected to the connecting pin 13 via the short cylinder portion 15a can be inserted. 17 is formed.

  Then, as shown in FIG. 10, with the opening 14 of the pair of divided bodies 11, 12 of the clamp tool C widely opened, the single pipe constituting the attachment member 103 is connected to the inside of the clamp tool C from the opening 14. Then, the fixing bolt 15 is inserted into the bolt insertion groove 17 of the divided body 12, and in this state, the nut 18 is screwed into the fixing bolt 15 and tightened. The clamp C is firmly clamped with respect to the single pipe.

As shown in FIGS. 6 to 9, the insertion locking tool E ₁ is attached to the upper surface side of the clamp tool C so as to be rotatable about the rotation axis B through a slide allowance tool 24. The insertion locking tool E ₁ is a single tube by inserting and locking the respective insertion locking plate portions 1 integrally provided at both ends in the inclined direction (short direction) of the solar panel P in the inclined arrangement state. It is a member for enabling the solar panel P to be attached to the attachment member 103 made of the above without using any bolts, and the configuration itself is extremely simple. That is, the insertion locking tool E ₁ includes an insertion locking groove 22 having a U-shaped cross section in a state including the substrate portion 21 at both end portions along the inclined direction Q of the substrate portion 21 in the inclined arrangement state. Each of the shapes 23 is provided. The insertion openings 22 a and 23 a of the insertion locking grooves 22 and 23 face each other along the inclination direction Q.

Then, as shown in FIGS. 10B and 11B, a plurality of solar panels P along the inclination direction Q in the arrangement example of FIG. The necessary number of the insertion locking devices E ₁ is 5). The solar panel above the diagonally adjacent to each of the insertion locking grooves 22 and 23 of the specific insertion locking device E ₁ along the inclination direction Q. In a state where the insertion locking plate portion 1 on the oblique lower end side of the P and the insertion locking plate portion 1 on the oblique upper end side of the solar panel P obliquely below are inserted and locked, respectively, The insertion locking plate portion 1 on the oblique lower end side of the upper solar panel P does not reach the inner end of the insertion locking groove 22 obliquely above the insertion locking tool E ₁ , but the oblique slope of the solar panel P below the diagonal. insert locking plate portion of the upper side 1, to abut the back end of the insertion fastener E ₁ oblique lower insertion locking groove 23 A relationship. In addition, since another solar panel P adjacent to the obliquely lower part is attached after the obliquely upward solar panel P is attached, the obliquely lower end face (the outer surface of the side plate portion 2) of the attached obliquely upward solar panel P is inserted. dimension L ₃ between the insertion opening 23a of the swash lower side of the insertion locking groove 23 of the locking part E ₁ [see FIG. 11 (a)], in a state in which oblique upper solar panel P is mounted, adjacent oblique A dimension (hereinafter referred to as “insertion locking plate of solar panel for later insertion”) that allows the insertion locking plate portion 1 of another lower solar panel P to be inserted into the insertion locking groove 23 obliquely below the insertion locking tool E _1. It is indispensable that the dimension is “a dimension in which the part can be inserted”.

Therefore, when the dimensions from the rotation axis B of the insertion locking tool E ₁ to the back ends of the insertion locking grooves 22 and 23 are L ₁ and L ₂ , the dimensions L ₁ and L ₂ are The relationship between the width dimension L ₄ of the insertion locking plate portion 1 of the solar panel P (see FIG. 11A) and the above-mentioned “dimension L _{3 at} which the insertion locking plate portion of the post-insertion solar panel can be inserted” Therefore, it is determined so as to satisfy all the above-mentioned conditions.

The insertion locking tool E ₁ described above is centered on the rotation axis B via the slide allowance tool 24 on the planar portion of the upper surface of the peripheral plate portion 11a of the divided body 11 on the upper surface side of the clamp tool C. It is pivotally mounted. When the solar panel P is attached to the two attachment members 103 adjacent to each other along the inclination direction via the clamp tool C and the insertion locking tool E ₁ , the slide allowance tool 24 is applied to the solar panel P with wind pressure or the like. Is a member for allowing the solar panel P to be finely moved in the lateral direction R and preventing the solar panel P from being partially damaged.

Slide acceptable tool 24, the upper surface side of the permissible tool body 25 having a groove 20 Yes over the entire length is formed, the insertion fastener fitted portion 26 formed along the transverse direction R on the back of the E ₁ Similarly, the fitting portion 27 fitted in the configuration is provided along the lateral direction R. Since the cross-section of the fitting portion 27 is circular and the cross-section of the fitted portion 26 is an arc having a central angle exceeding 180 °, the fitting body 25 is fitted to the fitted portion 26. In the state in which the joint portion 27 is fitted, the sliding can be performed only in the lateral direction R without the fitting being released. Furthermore, the compression springs 28 are arranged on both sides of the fitting portion 27 in a state where the fitting portion 27 of the allowance tool main body 25 is fitted to the fitted portion 26. A closing body 29 is disposed outside each compression spring 28 in the fitted portion 26, and the closing body 29 is fixed to the fitted portion 26 by a set screw 30.

  Further, a flat surface portion is formed on the upper surface of the peripheral plate portion 11a of the divided body 11 on the upper side of the clamp tool C, and a locking bolt 32 is screwed to the central portion of the flat surface portion. The hexagonal head 32a is used as a locking portion. That is, the width of the two-sided width portion of the hexagonal head portion 32a of the locking bolt 32 corresponds to the width of the dovetail groove 20 of the slide allowance 24, and the head portion 32a of the locking bolt 32 slides. The head 32 a of the locking bolt 32 does not rotate with respect to the slide allowance 24 in a state where it is inserted into the dovetail groove 20 of the allowance 24.

Thus, Figure 1, as shown in FIGS. 3 and 12, two adjacent along a single solar panel P in the inclined direction through the total of four clamping part C and the same number of insertion fastener E ₁ When the solar panels P are attached to the installation base V along the inclination direction Q and the lateral direction R, the gap 33 is formed between the solar panels P adjacent to each other along the inclination direction Q. (See FIG. 10) is formed, and a gap 34 (see FIG. 12) is formed between the solar panels P adjacent in the lateral direction R. And when wind pressure, impact, vibration, etc. act on the solar panel P, the lateral direction R has a vibration isolation structure that can absorb vibrations acting on the solar panel P, and the solar panel P After the fine movement in the lateral direction R, it is returned to its original position by the elastic restoring force of the compression spring 28.

For this reason, the solar panel mounting device D ₁ is a total of four “mounting devices” when the member in which the insertion locking tool E ₁ is mounted on the upper surface side of the clamp tool C is referred to as “mounting device alone”. “Single” is configured. In the drawing, in order to avoid the redundancy and complexity of entering the code, the code “D ₁ ” is attached to the portion corresponding to the “mounting device alone”.

The number of the insertion fastener E ₁ to be used along the inclination direction Q is the same as the number of the mounting member 103, the number obtained by adding 1 to the number of arranged solar panels P along the inclination direction Q It is. Of the plurality of insertion locking devices E ₁ arranged along the inclination direction Q, the intermediate insertion locking device E ₁ excluding both ends in the inclination direction Q is inclined in the insertion locking grooves 22 and 23. Although each insert locking plate portion 1 of the two solar panels P which are adjacent to each other along the direction is locked respectively inserted into and engaged, at both ends inserted fastener E ₁ of 'along the inclined direction, the uppermost oblique upper end, respectively Since the insertion locking plate 1 at the oblique upper end and the oblique lower end of each solar panel P at the lowermost part and the lowermost oblique part is only inserted and locked, the insertion locking tool E ₁ ′ The insertion locking tool E ₁ provided with the locking grooves 22 and 23 has a structure in which the insertion locking groove 22 (23) on the unused side is omitted (see FIGS. 2 and 5). That is, in FIG. 7, in the portions indicated by the missing lines K ₁ and K ₂ , each insertion locking tool E ₁ ′ from which the board portion 21 of the insertion locking tool E ₁ is missing is connected to the oblique upper end of the solar panel P. Used at the bottom and oblique lower end.

And, as shown in FIG. 1, in order to attach the solar panel P from the obliquely upward to the obliquely downward direction along the inclination direction Q to the respective attachment members 103 made of a single tube constituting the installation base V, the following To do so. In FIGS. 1, 10 and 11 only, a subscript is added to the original symbol (P) in order to specify a plurality (four) of solar panels P arranged along the inclination direction Q. In addition, the uppermost solar panel is displayed as (P ₁ ), and the second and subsequent solar panels are displayed as (P _{2 to} P ₄ ). First, in order to attach the solar panel P ₁ to the highest portion along the inclination direction Q, as shown in FIG. 10 (a), the installation arranged at the highest position (topmost level) along the inclination direction Q. The solar panel P ₁ is clamped in the insertion locking groove 23 of the insertion locking tool E ₁ ′, which is clamped with respect to the member 103 and connected to the clamping tool C via the slide allowance tool 24. Insertion locking plate portion 1 on the higher side is inserted and locked, and in this state, the solar panel mounting device [exactly “mounting device alone”] D ₁ in the air is inserted. the insertion locking groove 22 serving as the high side of the locking part E _1, thereby locked insertion locking plate 1 serving as a low the solar panel P ₁ side inserted and latched.

Next, as shown in FIG. 10 (b), Solar in a state described above, the insertion fastener E inserted locking groove inserted locking plate portion 1 of the lower side 22 of ₁ is inserted and locked The panel P ₁ is rotated downward about the rotation axis B of the insertion locking tool E ₁ arranged on the highest side, and the clamp tool C having the opening 14 opened widely is inclined. And clamping to another mounting member 103 adjacent to the mounting member 103. Thus, the solar panel P ₁ is attached to the two attachment members 103 adjacent to each other along the inclination direction Q in the uppermost stage along the inclination direction Q. In a state where the solar panel P ₁ is attached to two mounting members 103 adjacent, by gravity, the solar panels P _1, since lowered along the inclined direction Q, the higher side insertion locking plate 1, Although it is in contact with the back end face of the insertion locking groove 23 of the insertion locking tool E ₁ ′, the tip of the lower side insertion locking plate portion 1 is inserted on the higher side of another insertion locking tool E _1. A slight gap 41 is formed without contacting the back end surface of the stop groove 22.

In order to attach the solar panels P _{2 to} P ₄ in the second and subsequent stages, excluding the uppermost stage, to the two adjacent attachment members 103, an operation similar to the above may be repeated. That is, as shown in FIG. 11A, the insertion locking plate E attached to the lower surface of the _second solar panel P ₂ on the upper surface side of another clamping device C is inserted. _In the state inserted into the insertion locking groove 22 on the higher side of ₁ , the insertion locking plate portion 1 on the higher side of the _second solar panel P ₂ is connected to the lower side plate portion of the installed solar panel P _1. 2 and the insertion opening 23 a of the insertion locking groove 23 on the lower side of the insertion locking tool E ₁ , and the second-stage solar panel P ₂ is disposed substantially along the inclination direction Q.

In this state, the insertion locking plate portion 1 on the higher side of the second-stage solar panel P ₂ is placed on the substrate portion 21 of the insertion locking device E ₁ , and the clamping device C in the unclamped state is temporarily attached to the mounting member 103. After the holding, when the entire solar panel P ₂ is slightly slid downward along the inclination direction Q, the insertion locking plate portion 1 on the higher side of the solar panel P ₂ becomes the insertion locking tool. By being inserted into the insertion locking groove 23 on the lower side of E ₁ , the unclamped clamp C is slightly rotated counterclockwise, and the second solar panel P ₂ The solar panel P ₁ is disposed on the same inclined surface. Finally, to clamp the clamping part C of the non-clamping state with respect to the mounting member 103, the second stage of the mounting of the solar panel P ₂ is completed. The third and fourth solar panels P ₃ and P ₄ are attached to two adjacent attachment members 103 along the inclination direction Q by the same operation as the _second solar panel P ₂ .

In addition, the insertion locking plate portion 1 of the solar panel P is inserted and locked with no gap in the insertion locking groove of the insertion locking tool to prevent the occurrence of “rattle” of the solar panel P in the mounted state. Examples of the structure include the following.

Accordingly, the board portion 66 of the insertion locking tool E ₅ has a rectangular shape with a long and narrow ratio that is long in the lateral direction R in the arrangement state, and both ends of the board portion 66 in the longitudinal direction (lateral direction R in the arrangement state). Insertion locking grooves 67 and 68 are provided in the respective portions so as to face each other along the inclination direction Q.

Accordingly, as shown in FIG. 18, in the portion where the two solar panels P are adjacent along the lateral direction R, the two insertion locks E ₁ can be replaced with one insertion lock E ₅ . This makes it possible to halve the number of insertion locks used in the portion where the two solar panels P are adjacent along the lateral direction R. In addition to this, since two solar panels P adjacent along the lateral direction R are integrally connected, a total of four corner portions in the interior are adjacent along the inclined direction Q and the lateral direction R. A total of four solar panels P are integrally connected at each corner, and the connection strength of a large number of solar panels P each having a plurality of solar panels P arranged along the inclination direction Q and the lateral direction R is increased. The structure is strong against wind pressure and vibration.

The solar panel mounting device D ₃ shown in FIG. 17 has a configuration in which an insertion locking tool E ₅ is integrally provided on the upper surface side of the clamp tool C. However, the solar panel mounting device D ₁ of the first embodiment is inserted. It is also possible to attach the above-described insertion locking tool E ₅ instead of the locking tool E ₁ .

A solar panel mounting device D ₄ of the fourth embodiment shown in FIG. 19 is a device for mounting the solar panel P to the angle-shaped mounting member 105, and constitutes the solar panel mounting device D ₁ of the _first embodiment. insertion engagement combinations comprise only the case member E ₁ and the slide acceptable accessory 24, the solar panel mounting device D ₁ of the first embodiment, clamp fixture the slide acceptable accessory 24 via the locking bolt 32 to Although it is latched by C, it is the structure latched by the horizontal plate part 105a of the angle-shaped attachment member 105 via the latching bolt 71 so that a fine movement is possible in the horizontal direction R. In FIG. 19, 71 a is a head of the locking bolt 71 inserted and locked in the dovetail groove 20 of the slide allowance tool 24, and 72 is a locking bolt 71 on the inner side of the angle-shaped mounting member 105.
