When installing the crossarm 501, the specified position of the outer surface of the fixed frame 502 and the specified position of the fixed bar 301 are drilled through other equipment.

[0049] Example 3

[0050] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , which is the third embodiment of the present invention, and this embodiment is based on the previous embodiment. The drainage component 3 comprises a fixed bar 301 arranged on the lower surface of the cross arm 501, and the lower surface of the fixed bar 301 is slidably connected with a water guide plate 303, and the inside of the water guide plate 303 is fixedly connected with two connecting blocks 304, and the inside of the connecting block 304 is fixedly connected with a compression spring 305, and the end of the compression spring 305 away from the connecting block 304 is fixedly connected with a plug-in rod 306, and the inside of the fixed frame 502 is fixedly connected with a limiting bar 302, and the bottom end of the fixed frame 502 is fixedly connected with a connecting seat 310, and the inside of the connecting seat 310 is slidably connected with a baffle 309 for limiting the water guide plate 303, and the inside of the fixed bar 301 is fixedly connected with a plurality of vertical springs 307, and the bottom end of the vertical spring 307 is fixedly connected with a support block 308.

[0051] Specifically, the cross section of the water guide plate 303 is M-shaped, the upper surface of the water guide plate 303 is provided with a protrusion, the lower surface of the fixing bar 301 is provided with a groove matching the protrusion, the outer surfaces of the water guide plate 303 and the fixing frame 502 are provided with a round hole matching the plug rod 306, the interior of the locking block 205 is provided with a plug hole matching the plug rod 306, the outer surface of the support block 308 is provided with an inclined surface, the top of the fixing frame 502 is provided with a closing plate, and the top upper surface of the water guide plate 303 is fixed. There are two inclined blocks 311 in the fixed connection, the outer surface of the inclined block 311 abuts against the lower surface of the cross arm 501, long strip-shaped limiting protrusions are set at both ends of the baffle 309, and a slide groove matching the limiting protrusions is set inside the connecting seat 310. The distance between the two connecting blocks 304 is the same as the width of the limiting strip 302. A pin is inserted at the bottom end of the baffle 309, and a sub-groove matching the pin is set on the inner wall of the slide groove. A rectangular opening is set on the side of the connecting seat 310 away from the water guide plate 303.

[0052] Further, after the water guide plate 303 is inserted into the interior of the fixed frame 502 and the cross arm 501, and the water guide plate 303 and the connecting block 304 are inserted into the interior of the baffle plate 309, the plug-in rod 306 inside the connecting block 304 passes through the water guide plate 303 and the fixed frame 502 and is inserted into the interior of the locking block 205 by the action of the compression spring 305. After the insertion, the baffle plate 309 is rotated so that the baffle plate 309 is vertical to the connecting seat 310, and then the baffle plate 309 is inserted into the slide groove inside the connecting seat 310, and the baffle plate 309 is inserted into the slide groove inside the connecting seat 310. 09 The part extending out of the connecting seat 310 limits the connecting block 304. After the water guide plate 303 and the connecting block 304 are inserted into the interior of the baffle 309, the plug-in rod 306 inside the connecting block 304 passes through the water guide plate 303 and the fixed frame 502 through the action of the compression spring 305 and is inserted into the interior of the locking block 205. The part of the plug-in rod 306 extending out of the connecting block 304 is shorter, and the end of the plug-in rod 306 extending out of the connecting block 304 is a round head, so that the water guide plate 303 can be directly pulled out or inserted.

[0053] Working principle: When installing the photovoltaic bracket, several support frames 102 are installed on the roof at equal intervals, and then the cross bar 101 is installed on the support frame 102 by means of expansion screws and other tools, and then the fixing frame 502 drives the locking block 205 to prevent it from being on the cross bar 101, and then the fixing frame 502 is slid downward, driving the locking block 205 and the limit block 201 to slide downward, thereby driving the through groove inside the limit block 201 to cooperate with the plug formed between the two adjacent notches on the outer surface of the cross bar 101. Since the upper surface of the support frame 102 is inclined, the fixing frame 502 can be hung on the cross bar 101 through the limit block 201, and the two extrusion plates are driven to fit the outer surface of the cross bar 101 during the sliding process of the locking block 205, and the sliding During the movement, the cross bar 101 drives the extrusion block 202 and the extrusion spring 204 to move, so that the force applied by the extrusion spring 204 to the extrusion block 202 limits the two sides of the fixed frame 502, thereby preventing the fixed frame 502 from shaking inside the notch inside the cross bar 101, and then locking the U-shaped groove inside the clamping plate 203 by bolts and nuts, thereby further achieving the locking effect of the fixed frame 502, placing the cross arm 501 to be used on the upper surface of the fixed frame 502, and then rotating the rotating plate 402 to drive the limiting sleeve 404 to connect the hexagon socket bolts connecting the cross arm 501 and the fixed block 405, thereby fixing the distance between the two adjacent fixed blocks 405 and the cross arm 501, and then sliding the cross arm 501. The cross arm 501 and the fixing block 405 are moved to the designated position, the position is marked, and then the designated position of the outer surface of the fixing frame 502 and the designated position of the fixing strip 301 are drilled by a drilling device, so that the cross arm 501 is fixed to the designated position of the outer surface of the fixing frame 502 by a fixing screw, and the fixing block 405, the cross arm 501 and the fixing strip 301 are connected by hexagon socket bolts, and then the water guide plate 303 is inserted into the gap between the fixing frame 502 and the cross arm 501, and the two connecting blocks 304 are limited by the limiting strip 302, and the protrusion on the upper surface of the water guide plate 303 and the groove on the lower surface of the fixing strip 301 are limited, so that the water guide plate 303 is inserted into the fixing frame 502 and the cross arm 501. After the connecting block 304 is inserted into the interior of the baffle 309, the plug-in rod 306 inside the connecting block 304 passes through the water guide plate 303 and the fixing frame 502 through the action of the compression spring 305 and is inserted into the interior of the locking block 205. After the insertion, the baffle 309 is rotated so that the baffle 309 is vertical to the connecting seat 310, and then the baffle 309 is inserted into the sliding groove inside the connecting seat 310. The connecting block 304 is limited by the part of the baffle 309 extending out of the connecting seat 310 to prevent the water guide plate 303 from sliding out. Then the photovoltaic panel is installed on the cross arm 501. When the hexagon socket screws were installed previously, they were not tightened, so that the edge of the photovoltaic panel can be inserted into the gap between the cross arm 501 and the fixing block 405. Then the hexagon socket screws are rotated to fix the photovoltaic panel.Subsequently, the sealing strip is installed through the reserved groove on the upper surface of the sealing plate 401 to achieve sealing. When the water guide plate 303 needs to be maintained, the water guide plate 303 is pulled out through the same steps. The top upper surface of the water guide plate 303 is provided with an inclined surface, so that the debris on the upper surface of the water guide plate 303 can be pulled out together through the inclined block 311. After the water guide plate 303 is pulled out, the support block 308 inside the fixing strip 301 pops out under the action of the vertical spring 307, thereby supporting the fixing strip 301 and the center position of the cross arm 501 to prevent the cross arm 501 from bending and guiding. The photovoltaic panel is loosely installed. When the water guide plate 303 is subsequently inserted, the support block 308 is squeezed by the inclined surface of the outer surface of the support block 308, so that the support block 308 can return to the inside of the fixing bar 301, and finally the photovoltaic system is erected, which is convenient for pulling out the water guide plate 303 for maintenance, and can be conveniently installed and fixed by setting the locking component 2. The distance between adjacent cross arms 501 is controlled by the setting of the fixing component 4 to avoid uneven stress on the fixed position of the edge of the photovoltaic panel due to the different spacing between the cross arms 501 and the fixing block 405.
