First embodiment

1 illustrates a photovoltaic array assembly system 100 assembled on a roof R in accordance with a first embodiment of the present invention. As shown in FIG. 1, photovoltaic array assembly system 100 includes a photovoltaic array 110 and a plurality of support member sets 120. The photovoltaic array 110 is arranged by at least one photovoltaic module 111 which is fixedly spaced apart from each other on the roof R and holds at least one photovoltaic module 111, respectively.

2A is an enlarged view of a portion M1 of FIG. 1 at different viewing angles. 2B is an exploded view of the jig 200 and the base 121. As shown in Figures 2A and 2B, each support member set 120 includes a base 121 and at least one clamp 200. The base 121 is for fixing to the roof R, and the base 121 has a top surface 121S opposite to the roof R. The clamp 200 includes a bracket 210, a movable clamp 220, and a lock assembly 240. The movable clamp member 220 is slidably disposed on the bracket 210, and has a movable clamp member 220 and has at least one first clamping arm 221 . The locking assembly 240 locks the movable clamp 220 and the bracket 210 to the base 121 such that the photovoltaic module 111 is restrained between the first clamping arm 221 and the top surface 121S.

In this way, because any base is a short-track design compared to the prior art, it can be arbitrarily configured in accordance with the terrain limitation of the roof or the arrangement of the photovoltaic array, and the conventional long-shaped rail cannot be used on the roof because its length is too long. Disadvantages of arbitrary configuration. The length of any base, for example less than the length or even the width of any PV module. Therefore, the design of the photovoltaic array assembly system of the present invention can not only save material costs, reduce the load on the roof, but also reduce the space occupied on the roof.

In addition, since each of the bases 121 is independently fixed to the roof R by a lock SC (for example, a bolt), each of the bases 121 can provide sufficient support strength of the corresponding photovoltaic module 111, thereby reducing the plurality of photovoltaic modules 111 simultaneously. The risk of loosening or falling off the self-supporting member set 120.

It should be understood that those skilled in the art can flexibly select and place multiple fixtures on a single base according to actual needs.

The photovoltaic modules 111 of different specifications may have different sizes (such as thickness and width). Since the photovoltaic module 111 includes the body 111M and the outer frame 111F for covering the body 111M, the body 111M and the outer frame 111F of the photovoltaic module 111 may also have respectively Different sizes (such as thickness, width). Therefore, in order to stably fix the photovoltaic module 111 of most specifications, before the locking component 240 is locked, the movable clamping member 220 can slide up and down relative to the bracket 210 to match the size of the photovoltaic module 111, so that the photovoltaic module 111 has sufficient The space is inserted between the first clamping arm 221 of the movable clip 220 and the top surface 121S of the base 121. Such as Therefore, since the movable clamp 220 can drive the first clamping arm 221 to slide up and down, most kinds of photovoltaic modules, such as photovoltaic modules with standard outer frame or special outer frame, can be fixed to the movable clamp. The first clamping arm 221 of the 220 is between the top surface 121S of the base 121.

Specifically, as shown in Fig. 2B, the bracket 210 includes at least one riser 211. The riser 211 is substantially vertical with respect to the top surface 121S, and the movable clamp 220 slidably couples the riser 211 such that the movable clamp 220 can be along the long axis of the riser 211 of the bracket 210 (refer to the Z-axis) ) Actively moving up and down. As such, the first clamping arm 221 of the movable clamp 220 can be movably lowered to contact the photovoltaic module 111 in accordance with the thickness of the photovoltaic module 111; FIG. 3A is a cross-sectional view of FIG. 2A taken along line AA. As shown in FIG. 3A, the photovoltaic module 111 can be firmly clamped between the first clamping arm 221 of the movable clamp 220 and the top surface 121 S of the base 121 by the locking of the locking assembly 240.

Specifically, the bracket 210 of the first embodiment further includes a transverse plate 212. The cross plate 212 is placed on the top surface 121S of the base 121 (Fig. 3A) and contacts the top surface 121S of the base 121. The number of the risers 211 is two, and the two risers 211 are located at opposite ends of the transverse plate 212, and extend parallel to each other in a direction away from the top surface 121S, for example, according to the normal direction S of the top surface 121S, refer to the Z-axis: The extension, and the two vertical plates 211 and the transverse plates 212 together define an open space 214.

In the first embodiment, referring back to FIG. 2B, the movable clamp 220 includes two mutually symmetrical openings 222, each of which is configured to allow one of the risers 211 to extend therein such that each riser 211 is slidably disposed therein. A breach 222 inside.

The movable clip 220 further includes a U-shaped body 223, and the number of the first clamping arms 221 is two. The two first clamping arms 221 are respectively located at opposite ends of the U-shaped body 223, respectively extending in the opposite directions D1, D2 with reference to the X-axis:) horizontally and away from each other. Two breaks 222 are respectively opened on the two first clamping arms 221 .

Thus, when the photovoltaic module 111 is placed on the top surface 121 S of the base 121, the movable clamp 220 cooperates with the thickness of the photovoltaic module 111 to engage the riser 211 in the direction D3 (refer to the Y-axis), and allows the two risers 211 to be respectively Extend into the two breaches 222. Then, through the sliding of the movable clip 220, the photovoltaic module 111 is constrained between the first clamping arm 221 and the top surface 121S, respectively. The direction D3 is orthogonal to the normal direction S with reference to the Z axis:) and the direction D1 with reference to the X axis:).

Since the two vertical plates 211 are respectively located in the two breaks 222, when the photovoltaic module 111 is clamped between the movable clamp 220 and the base 121 (Fig. 2A), the movable clamp 220 is not on the riser 211. The rotation is generated to prevent the photovoltaic module 111 from being detached from the movable clip 220 and the base 121 after multiple vibrations. However, the present invention is not limited thereto, and those skilled in the art may also flexibly select the number of photovoltaic modules held by the same movable clip according to actual needs. For example, two parallel photovoltaic modules 111 are respectively restrained by the same support member group 120. The opposite side of the two sides (as in the partial M2 of Figure 1).

In the first embodiment, the base 121 is elongated and the base 121 includes a groove 122 and a notch 123. The groove 122 is connected to the notch 123, and both extend along the long axis direction L1 of the base 121 (refer to the X axis). The notch 123 is formed in the top surface 121 S, and the width W1 of the notch 123 is smaller than the width W2 of the groove 122 (Fig. 3B:). The locking assembly 240 includes a bolt 241 and a nut 242 (such as a hex nut or a butterfly nut, etc.). The bolt 241 includes a bolt head 241A and a bolt body 241B. The bolt head 241A is embedded in the groove 122 and is only slidably located in the groove 122 and cannot be removed from the notch 123. One end of the bolt body 241B is connected to the bolt head 241Ao. The nut 242 is screwed into the bolt body 241B from the U-shaped body 223 of the movable clamp 220. The bolt head 241A and the nut 242 of the locking assembly 240 sandwich the movable clamp 220, the bracket 210 and the base 121 (Fig. 3A). However, the invention is not limited thereto, and in other embodiments, the nut may be replaced with a clip, a pin or other suitable knot.

Referring back to Figure 2B, the base 121 further includes at least one bolt head inlet 125A. The bolt head inlet 125A is located on one side of the base 121 for the bolt head 241 A of the bolt 241 to enter the groove 122. However, the present invention is not limited thereto, and in other embodiments, the bolt head inlet may be modified to be opened at one end of the base.

Fig. 3B is a cross-sectional view taken along line BB of Fig. 2B. As shown in FIG. 3B, the base 121 further includes an elongated slot 124 extending from the bottom surface of the base 121 opposite the top surface 121S (FIG. 2B) and extending along the longitudinal axis L1 of the base 121. The groove 122 is located between the slit 124 and the notch 123, and the slit 124 closes the groove 122 and the notch 123. When the base 121 is placed on the roof R, the elongated slot 124 faces the roof R, so that the above-described locker SC (Fig. 2B) can pass through the elongated slot 124 and be locked to the roof R. The locker SC is, for example, a self-drilling screw and cannot be pulled out after it has been driven into the roof R.

Therefore, as shown in FIG. 3A, when the base 121 has been locked to the roof R by the lock SC, the bolt head 241A of the bolt 241 first enters the groove 122 through the bolt head inlet 125A (Fig. 2B); The bolt body 241B passes through the through hole 213 of the transverse plate 212 from the notch 123. At this time, the bolt head 241A abuts against the inner wall of the base 121 opposite the top surface 121 S in the groove 122. Then, the photovoltaic module 111 is placed on the base 121. The top surface 121 S is adjacent to one side of the bracket 210; then, the bolt body 241B is passed through the through hole 224 of the bottom of the U-shaped body 223 so that the first clamping arm 221 of the U-shaped body 223 contacts the photovoltaic module 111; Next, the nut 242 is screwed to the bolt body 241B with respect to the bolt head 241A to abut against the U-shaped body. The bottom of the 223 faces away from the side of the base 121 and is locked toward the base 121 such that the movable clamp 220, the bracket 210 and the base 121 are clamped together. Thus, since the movable clip 220, the bracket 210 and the base 121 are clamped together, the photovoltaic module 111 interposed between the first clamping arm 221 and the top surface 121 S of the base 121 can also be firmly clamped to The first clamping arm 221 is between the top surface 121 S of the base 121 .

In addition, as shown in FIG. 3A , since the bottom of the U-shaped body 223 and the two first clamping arms 221 maintain a vertical drop G between each other, the bottom surface of the U-shaped body 223 is closer to the base 121 than the first clamping arm 221 . The top surface 121S, therefore, the bolt body 241B of the bolt 241 only needs to protrude from the bottom of the U-shaped body 223, and does not need to extend to the same plane of the first clamping arm 221, thereby saving the length of the bolt body 241B.

4 illustrates a photovoltaic array assembly system 100 assembled on a tilted roof R in accordance with a first embodiment of the present invention. As shown in FIG. 4, although the locking component 240 clamps the base 121, the movable clamp 220 and the bracket 210 together, the bracket 210 may still slide along the top surface 121S of the base 121, thereby allowing the first clamping arm to be clamped. The photovoltaic module 111 between the 221 and the base 121 slides off the roof R to the ground. In this regard, the top surface 121 S of the base 121 includes a plurality of first stops 130. The first stopping portion 130 is protruded from the top surface 121S of the base 121 and is spaced apart from the top surface 121 S. The bracket 210 includes a plurality of second stops 215. The second stoppers 215 are convexly and spacedly arranged at the bottom of the bracket 210. As such, when the photovoltaic array assembly system 100 is assembled to an inclined surface RS of the roof R, the displacement of the second stop portion 215 is blocked by the first stopping portion 130, thereby limiting the displacement of the bracket 210 and the photovoltaic module 111. The opportunity for the photovoltaic module 111 to slip off the roof R is reduced.

In addition, by the mutual contact between the first stopping portion 130 and the second stopping portion 215, the installer can know the reference point at which the bracket 210 should be placed without using the measuring rule, so as to shorten the operation of the installer placing the bracket 210 on the base 121. time.

5A to 5C illustrate changes in the appearance of the first stopper of the base of the first embodiment of the present invention. The shape change of the first stopper portion may be a cylindrical body 131 (Fig. 5A), a trapezoidal body 132 (Fig. 5B) or a circular arc body 133 (Fig. 5C), etc., however, the present invention is not limited to the outside of the first stopper portion. Type change and quantity.

As shown in FIG. 5A, since the side 131A of the cylindrical body 131 is approximately perpendicular to the top surface 121S of the base 121, the bracket 210 must vertically rise above the height of the side edge 131A to allow the second stop portion 215 to span the cylindrical body 131. The chance of the second stop 215 passing through the cylindrical body 131 (ie the first stop) is reduced.

As shown in FIG. 5B, since the inclined surface 132A of the trapezoidal body 132 is inclined relative to the top surface 121S of the base 121, when the installer wants to cause the bracket 210 to straddle the trapezoidal body 132, the installer only needs to have the second stop portion 215 The inclined surface 132A rises to leave the top surface 121S, so as to straddle the trapezoidal body 132 (ie, the first stop portion), Save more manpower.

Furthermore, as shown in FIG. 5C, since the curved surface 133A of the circular arc body 133 is inclined relative to the top surface 121 S of the base 121, when the installer wants to cause the bracket 210 to cross the circular arc body 133, the installer only needs to The second stopping portion 215 is raised along the curved surface 133A to leave the top surface 121S, so that the circular arc body 133 (ie, the first stopping portion) can be crossed to save more manpower.

However, the appearance and the number of the first stoppers of the present invention are not limited thereto, and the shape and the number of the second stoppers can be flexibly selected by those skilled in the art according to the above disclosure.

Second embodiment

6A to 6C illustrate changes in the appearance of the first stopper of the base according to the second embodiment of the present invention. Referring to FIG. 6A to FIG. 6C , the second embodiment is substantially the same as the first embodiment. The difference is that the first stop portion is recessed on the top surface 121S of the base 121 , for example, a square groove 134 ( FIG. 6A ). The trapezoidal groove 135 (Fig. 6B) or the circular arc groove 136 (Fig. 6C) or the like allows the second stopper portion 215 to extend into and be constrained therein. However, the invention is not limited to the variation and number of appearances of the first stop.

As shown in FIG. 6A, since the shape of the square groove 134 allows the second stopper portion 215 to be more easily positioned therein, and the second stopper portion 215 requires more force to move out of the square groove 134, the second portion is lowered. The chance of the stop 215 being disengaged from the square groove 134 (ie the first stop).

As shown in Fig. 6B, the shape of the trapezoidal groove 135 allows the second stopper portion 215 to fall more easily with respect to the square groove 134 of Fig. 6A.

As shown in Fig. 6C, the shape of the circular arc groove 136 is such that the second stopper portion 215 is more likely to fall therein than the square groove 134 of Fig. 6A.

In addition, the person skilled in the art can also flexibly select the appearance and number of the second stopping portion according to the above disclosure.

Referring to FIG. 7A, the third embodiment is substantially the same as the first embodiment, and one of the differences is that the base 121 includes at least one fluid guiding portion 126A. Since the fluid guiding portion 126A has a conductive angle on the structure, it is also referred to as a lead angle fluid guiding portion. The fluid guiding portion 126A is located at one end portion 121E of the base 121, and can guide the fluid F (such as rainwater) to flow through the base 121 as soon as possible. Specifically, when the base 121 is assembled to the inclined surface RS of the inclined roof R, the base 121 is disposed on the inclined surface RS in accordance with the height of the inclined surface RS. The fluid guiding portion 126A is located on the higher end portion 121E and is connected to the inclined surface RS. Since the lead angle of the fluid guiding portion 126A extends toward the inside of the base 121, when the fluid F (such as rain) hits the fluid guiding portion 126A and is blocked by the fluid guiding portion 126A, the fluid F (such as rain) is forced. Splits are generated and are respectively removed along the sides of the base 121 to bypass the base 121, reducing the time during which the bolts or fasteners are rusted.

As shown in Fig. 7B, since the lead angle of the fluid guiding portion 126B is extended outward, when the fluid F (e.g., rainwater) hits the fluid guiding portion 126B and is guided by the fluid guiding portion 126B, the fluid F (e.g., rainwater) is The flow is divided and separated along the sides of the base 121 to bypass the base 121 instead of splashing over the base 121 to reduce the time during which the bolt or the lock is rusted. Compared to the fluid guiding portion 126A of Fig. 7A, the fluid guiding portion 126B of Fig. 7B is less prone to splashing, reducing the chance of fluid F (e.g., rain) splashing onto the base 121.

Or, as shown in FIG. 7C, since the lead angle of the fluid guiding portion 126C is arcuate, when the fluid F (such as rain) hits the fluid guiding portion 126C and is guided by the fluid guiding portion 126C, the fluid F ( For example, rainwater cannot rest on the fluid guiding portion 126C, and is further branched to leave along both sides of the base 121 to bypass the base 121, reducing the time during which the bolt or the lock is rusted.

However, the present invention is not limited thereto, and the fluid guiding portion may be located at the side of the base or may have a fluid guiding portion at the end and the side.

Fourth embodiment

Since the roof has a plurality of spaced support steel beams (not shown), the base can be coupled to the supporting steel beam by means of a lock. However, in order to match the position of the photovoltaic module, the base may not be located just above the supporting steel beam of the roof. Above, for this purpose, a plurality of interconnected bases can be extended from any position on the roof to above the supporting steel beams of the roof, thereby being connected to the supporting steel beams of the roof.

Figure 8 is a partial side elevational view of the base 121 in accordance with a fourth embodiment of the present invention. Referring to FIG. 8, the fourth embodiment is substantially the same as the first embodiment, and one of the differences is that at least two bases 121 are connected to each other. The base 121 has a strip-shaped base 121B, a first connecting portion 128 (e.g., a rib) and a second connecting portion 129 (e.g., a hook). The first connecting portion 128 and the second connecting portion 129 are respectively located at opposite ends of the strip-shaped base 121B. Thus, as shown in FIG. 8, the first connecting portion 128 of the left base 121 and the second connecting portion 129 of the right base 121 are matched to each other in the outer shape, and are engaged with each other to realize any on the roof R. The purpose of the extension. In addition, the first connection portion 128 and the second connection portion 129 can also be used to block the photovoltaic module 111 to reduce the chance of the photovoltaic module 111 slipping off the roof R.

Fifth embodiment FIG. 9 is a partial enlarged view of the movable clip 220 according to the fifth embodiment of the present invention. Referring to FIG. 2B and FIG. 9 , the fifth embodiment is substantially the same as the first embodiment, and one of the differences is that the bracket 210 includes a first conductive layer 217 (such as a metal layer) and a first insulating layer 218 (eg, anodized). Floor). The first insulating layer 218 encapsulates the first conductive layer 217, and the first insulating layer 218 has a first exposed region 219 exposing the first conductive layer 217. The photovoltaic module 111 (such as an outer frame) includes a second conductive layer 112 (such as a metal layer) and a second insulating layer 113 (such as an anodized layer). The second insulating layer 113 covers the second conductive layer 112, and the second insulating layer 113 has a second exposed region 114 exposing the second conductive layer 112. The movable clip 220 includes at least one first scraping portion 225 and at least one second scraping portion 226. The first scraping portion 225 is opposite to the first exposed portion 219 and electrically connected to the first conductive layer 217. The second scraping portion 226 is electrically connected to the second conductive layer 112 and the first conductive layer 217 with respect to the second exposed region 114 .

In detail, the first scraping portion 225 is serrated and is located on the opposite outer side walls of the U-shaped body 223 for contacting the riser 211. The second scraping portion 226 is also serrated and is located on the lower surface of each of the first clamping arms 221 for contacting the photovoltaic module 111.

When assembled, when the movable clip 220 is engaged with the riser 211 (FIG. 2B) in cooperation with the thickness of the photovoltaic module 111, so that the two risers 211 just extend into the two breaks 222, respectively, the U-shaped body 223 enters the open space. 214, and is sandwiched between the two risers 211, that is, the U-shaped body 223 begins to physically contact the two vertical plates 211 facing the inner wall of the open space 214.

At this time, the first scraping portion 225 simultaneously scrapes off the portion of the first insulating layer 218 on the riser 211 in accordance with the movement of the U-shaped body 223. The portion of the first insulating layer 218 that is scraped off by the first scraping portion 225 is the first exposed portion 219. The first scraping portion 225 is electrically connected to the first conductive layer 217 in the first exposed portion 219.

At the same time that the first scraping portion 225 scrapes off a portion of the first insulating layer 218, since the movable clip 220 is engaged with the riser 211 in cooperation with the thickness of the photovoltaic module 111, the second scraping portion 226 also The movement of the first clamping arm 221 simultaneously scrapes off a portion of the second insulating layer 113 on the photovoltaic module 111 (ie, the outer frame). A portion of the second insulating layer 113 scraped off by the second scraping portion 226 is the second exposed region 114, and the second scraping portion 226 is electrically connected to the second conductive layer 112.

Since the movable clip 220 is electrically connected to the first conductive layer 217 on the bracket 210 through the first scraping portion 225, and electrically connected to the second conductive layer on the photovoltaic module 111 through the second scraping portion 226. 112. Therefore, the bracket 210 is also electrically connected to the photovoltaic module 111. Thus, since the bracket 210 is indirectly electrically connected to the grounding end (not shown) through the locking component 240, the constrained and clamped photovoltaic module 111 and the grounding end A conductive path is created between them, allowing the photovoltaic module 111 to be grounded through the conductive path.

Sixth embodiment

Referring to FIG. 10, FIG. 10 is a partial side elevational view of the photovoltaic array assembly system 100 assembled on the roof R according to the sixth embodiment of the present invention, the local position of which is the same as the portion M1 of FIG. In actuality, the roof R has reinforcing ribs RB, which may hinder the placement of the base 121, the jig 200 or the photovoltaic module 111 due to the height of the reinforced ribs RB.

In this regard, the sixth embodiment is substantially the same as the first embodiment, and one of the differences is that the jig 200 further includes a support frame 230. The support frame 230 is located between the bracket 210 and the top surface 121 S of the base 121, and the support frame 230 has at least one second clamping arm 231. The locking assembly 240 locks the movable clamp 220, the bracket 210 and the bracket 230 to the base 121 such that the photovoltaic module 111 is directly clamped between the first clamping arm 221 and the second clamping arm 231. Specifically, the bolt head 241A and the nut 242 sandwich the base 121, the support frame 230, the bracket 210, and the movable clamp 220. Thus, since the base 121, the support frame 230, the bracket 210 and the movable clamp 220 are clamped together, the photovoltaic module 111 interposed between the first clamping arm 221 and the second clamping arm 231 can also be firmly It is sandwiched between the first clamping arm 221 and the second clamping arm 231.

Specifically, the support frame 230 further includes a base 232 for placing on the top surface 121S of the base 121 and contacting the top surface 121 S of the base 121. The base 232 extends away from the top surface 121 S of the base 121, for example, according to the normal direction S of the top surface 121 S (refer to the Z axis). In addition, the number of the second clamping arms 231 is two, and the two second clamping arms 231 are respectively located on opposite sides of the base 232, horizontally extending in opposite directions (refer to the X axis:) and mutually mutually keep away. The support frame 230 further includes two diagonal reinforcing ribs 233. Each of the diagonal reinforcing ribs 233 connects one of the second clamping arms 231 and the base 232 to strengthen the strength of the second clamping arm 231 to support the photovoltaic module 111.

It should be understood that, since the support member group of the present invention does not need to be limited in the arrangement of the photovoltaic modules, the base can be configured in any direction on the roof. For example, after the base 121 is fixed to the roof R, the clamp 200 can be the bolt body 241B. The shaft is arbitrarily rotated to match the arrangement of the photovoltaic modules 111.

Thus, since the jig 200 can be arbitrarily rotated, the long-axis direction L1 of the base 121 (FIG. 2B) can intersect the long-axis direction L2 of the side of the photovoltaic module 111 (FIG. 2A), or with the side of the photovoltaic module 111. The long axis directions L2 are parallel to each other (such as the portion M2 of FIG. 1; > in other words, the support member group 120 is not necessarily disposed on the side of the photovoltaic module (such as the portion M2 of FIG. 1), or at the same time over the photovoltaic module. Below (partial Ml of Figure 1).

Referring to FIG. 10, in order to improve the convenience of the support frame 230 being placed on the base 121, the support frame 230 At least one second stop 234 is included. In this way, by the mutual contact between the first stopping portion 130 and the second stopping portion 234, the installer can know the reference point at which the support frame 230 should be placed without using the measuring rule, so as to shorten the installation personnel to place the supporting frame 230 on the base 121. Operating time.

Although the locking component 240 clamps the base 121, the support frame 230, the movable clamp 220 and the bracket 210 together, the support frame 230 may still slide along the top surface 121 S of the base 121, thereby allowing the clamped photovoltaic module to be clamped. 111 slipped off the roof R. In this regard, as shown in FIG. 10, when the number of the first stopper portion 130 and the second stopper portion 234 is plural, the second stopper portion 234 is spaced apart from the one surface of the base 232 facing the base 121. As such, the displacement of the second stop portion 234 is blocked by the first stop portion 130, thereby limiting the displacement of the support frame 230 and the photovoltaic module 111 to reduce the chance of the photovoltaic module 111 slipping off the roof R.

In addition, in order not to cause interference when the support frame 230 travels on the base 121, the top surface 121S of the base 121 and the two adjacent second stop portions 234 define a clearance space 236, which allows the space to be opened. The 236 is configured to receive at least one first stopping portion 130 therein to smoothly abut the first stopping portion 130 and block the displacement of the second stopping portion 234.

Similarly, in order to shorten the operation time for the installer to place the bracket 210 on the support frame 230 and reduce the chance of the photovoltaic module 111 sliding off the roof R, the support frame 230 further includes at least a third stop portion 235, a third stop. The portion 235 is located on a side of the base 232 that faces away from the base 121. The bracket 210 further includes at least one fourth stop 216. The mutual restriction of the third stop portion 235 and the fourth stop portion 216, thereby limiting the displacement of the bracket 210 on the support frame 230, thereby reducing the chance of the photovoltaic array 110 sliding off the roof R to the ground.

In addition, by the limitation of the third stopping portion 235, the installer can also quickly position the photovoltaic module 111 on the second clamping arm 231, which can further shorten the operation of the installer to place the photovoltaic film group 111 on the support frame 230. Time, reduce the time to confirm that the photovoltaic module 111 is properly placed.

However, the present invention is not limited thereto, and those skilled in the art can flexibly select the appearance and number of the first to fourth stoppers 130 to 216 of the sixth embodiment according to the disclosure of FIGS. 5A to 6C. Please refer to the first embodiment and the second embodiment described above, and therefore, no further details are provided herein.

However, the present invention is not limited thereto, and in other embodiments, the bolt head inlet may be modified to be opened on one side of the base.

The base 121 further includes a shutter 138. The flap 138 is slidably located in the slot 123. A portion of the slot 121 is located in the slot 123, and the other portion protrudes from the slot 123 and is engaged with the top surface 121 S of the base 121. , to block the movement of the bolt 241 (Fig. 11).

Further, a side of the base 121 facing away from the top surface 121 S is recessed with a fluid guiding groove 127. When the base 121 is assembled to the inclined surface RS (FIG. 4) of the roof R, when a fluid (such as rainwater) flows directly from the base 121 and the inclined surface along the base 121 along the fluid guiding groove 127, the corrosion of the bolt is reduced. time.

In the seventh embodiment, the opposite ends of the base 121 have a first connecting portion 128 (such as a rib) and a second connecting portion 129 (such as a hook).
