Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic waterproof bracket connection mechanism. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] When installing a photovoltaic power generation device, you need to pre-install the bracket, that is, the main beam, and then install the cross beam on the main beam. After the cross beam is installed, you also need to install a support plate for drainage on the cross beam, and then install the cross arm on the support plate. Finally, install the photovoltaic panel on the support plate through the cross arm, and finally complete the installation of the photovoltaic system.

[0004] During the installation process of existing photovoltaic power generation devices, it is necessary to install the main beam, cross beam, support plate and cross arm in sequence to finally complete the installation of the photovoltaic panel. In addition, the main beam and the cross beam are fixedly connected by screws or connecting tools during the installation process, and the connection angle cannot be adjusted. This results in the location for installing the photovoltaic power generation device must be flat enough to ensure that the height of several main beams is consistent, which has low practicality.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] Example 1

[0042] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , is the first embodiment of the present invention, which provides a photovoltaic waterproof bracket connection mechanism, including a main beam 2 and a cross beam 1 arranged on both sides of the main beam 2, the outer surface of the main beam 2 is provided with a guide component 3, the guide component 3, including a sliding block 301 slidably connected to the outer surface of the main beam 2, the upper surface of the sliding block 301 is provided with a groove for guide, the sliding block 301 is interspersed with two guide plates 304, one of the guide plates 304 is fixedly connected to the surface of the side away from the sliding block 301 with a pressure plate 302, the end of the guide plate 304 away from the sliding block 301 is fixedly connected to two connecting blocks 305, a connecting plate 307 is arranged inside the connecting block 305, and a plug plate 308 is fixedly connected to the side of the connecting plate 307 away from the stretching connecting block 305.

[0043] Specifically, a tension spring 306 is fixedly connected to the inside of the connecting block 305, and one end of the tension spring 306 away from the connecting block 305 is fixedly connected to one side of the connecting plate 307. The cross-section of the plug plate 308 is L-shaped. The outer surface of the connecting block 305 is provided with a slot for plugging in the plug plate 308. The upper surface of the sliding block 301 is fixedly connected with a cross arm 303 for installing a photovoltaic panel. The interior of the sliding block 301 is provided with a slot that matches the two guide plates 304. The lower surface of the sliding block 301 is provided with a rectangular groove with the same width as the width of the main beam 2. The sliding block 301 slides on the outer surface of the main beam 2 through the rectangular groove, and a rubber strip for sealing is provided at the connection between the pressure plate 302 and the guide plate 304.

[0044] Further, two adjacent sliding blocks 301 are butted against each other through the guide plate 304, and the connecting blocks 305 fixedly connected to the outer surfaces of the two guide plates 304 are butted against each other. When butting against each other, the plug plate 308 is pulled out. After the two connecting blocks 305 are butted against each other, the plug plate 308 is released, and the plug plate 308 is retracted under the action of the connecting plate 307 and the tension spring 306, thereby driving the plug plate 308 to be inserted into the slot inside the other connecting block 305, so as to achieve the butt joint of the two guide plates 304.

When it rains, when rainwater passes through the gap between the two guide plates 304, it is guided by the pressure plate 302. After two adjacent sliding blocks 301 are fixed by the insertion rod 401, the distance between the adjacent sliding blocks 301 can ensure that the two guide plates 304 are connected.

[0045] Example 2

[0046] Reference Figure 1 , Figure 2 , Fig. 9 and Fig.10 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Two fixing components 4 are arranged inside the sliding block 301. The fixing component 4 includes an insertion rod 401 inserted into the sliding block 301. One end of the insertion rod 401 is fixedly connected to two limit blocks 402. The outer surface of the sliding block 301 is fixedly connected to a fixing block 404 for locking the limit block 402. The internal thread of the fixing block 404 is connected to two connecting pins 403 for locking the insertion rod 401.

[0047] Specifically, round holes for the movement of the insertion rod 401 are provided inside the sliding block 301 and inside the main beam 2, a circular sub-groove is provided on the inner side of the rectangular groove on the lower surface of the sliding block 301, away from the fixed block 404, and the diameter of the circular sub-groove is the same as the length of the two limit blocks 402. The side of the sliding block 301 close to the fixed block 404 and the inside of the fixed block 404 are provided with sliding grooves for the sliding of the limit blocks 402, and the inside of the fixed block 404 and the end of the insertion rod 401 close to the fixed block 404 are provided with sockets that cooperate with the connecting pin 403.

[0048] Furthermore, after sliding the sliding block 301 to a suitable position, the insert rod 401 is inserted through the circular holes in the sliding block 301 and the main beam 2, so that the insert rod 401 drives the limit block 402 to pass through the main beam 2 and out from the side of the sliding block 301 close to the fixed block 404, and then the insert rod 401 is rotated to drive the limit block 402 to rotate in the fixed block 404, so that the circular hole inside the insert rod 401 is docked with the circular hole inside the fixed block 404, so that the connecting pin 403 is inserted into the fixed block 404 and the insert rod 401 through the circular hole, and finally the sliding block 301 is fixed. The main beam 2 is pre-arranged with a circular hole, which is convenient for cooperation with the insert rod 401 to realize the positioning of the sliding block 301.

[0049] Example 3

[0050] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8, which is the third embodiment of the present invention. This embodiment is based on the previous embodiment. Two connecting components 5 are arranged inside the sliding block 301. The connecting component 5 includes two rotating disks 502 movably connected to the outer surface of the sliding block 301 through a connecting shaft. A rotating block 508 is fixedly connected between the two rotating disks 502. A clamping block 503 is interspersed inside the rotating block 508. One end of the clamping block 503 passes through the rotating block 508 and is movably connected to the plug-in block 501. One end of the plug-in block 501 is fixedly connected to the plug-in block 504. The end of the plug-in block 504 away from the plug-in block 501 is fixedly connected to one end of the beam 1.

[0051] Specifically, rectangular square grooves are provided on both sides of the sliding block 301, and the rotating disk 502 is movably connected to the inner wall of the rectangular square groove through a connecting shaft. A rectangular groove for plugging the crossbeam 1 is provided on the outer surface of the plug-in block 504. After the crossbeam 1 is inserted into the rectangular groove on the outer surface of the plug-in block 504, it is fixedly connected to the plug-in block 504 through a bolt. A through groove matching the clamping block 503 is provided inside the plug-in block 501, and two limit plates 505 are interspersed inside the rotating block 508. A socket matching the limit plate 505 is provided on the side of the clamping block 503 close to the limit plate 505. Two transverse springs 507 are fixedly connected to the end of the clamping block 503 away from the limit plate 505. The transverse spring 507 is fixedly connected to the inner wall of the rotating block 508. The bottom end of the limit plate 505 passes through the rotating block 508 and is fixedly connected to a pushing block 506. The outer surface of the rotating block 508 is provided with a rectangular sliding groove for moving the limit plate 505.

[0052] Further, the crossbeam 1 is docked with the plug-in block 504, and the crossbeam 1 is plugged into the slot inside the plug-in block 504. After the plug-in is completed, the plug-in parts of the crossbeam 1 and the plug-in block 504 are drilled with other tools, and then fixed and connected with bolts and nuts. Then, the crossbeam 1 is inserted into the gap between the rotating block 508 and the rectangular square groove on the side of the sliding block 301 through the plug-in block 504 and the plug-in block 501, and then the crossbeam 1 is placed downward. The distance between the upper surface of the inner wall of the rectangular square groove and the upper surface of the rotating block 508 is enough for the plug-in block 501 to be inserted, so that the plug-in block 501 is pressed downward on the rotating block 5 08, at this time, the through groove inside the plug block 501 is docked with the block 503, and by pressing the two push blocks 506, the limit plate 505 is driven to contact the limit of the block 503, and the block 503 pops up under the action of the transverse spring 507, thereby clamping the plug block 501 to achieve the installation of the beam 1. When the heights of adjacent main beams 2 are different, the beam 1 is driven to tilt by the rotating block 508 and the rotating disk 502. It should be noted that when the heights of adjacent main beams 2 are different, the length of the beam 1 used should also be changed accordingly, so that the beam 1 can be well installed between two adjacent main beams 2.

[0053] Working principle: When installing the photovoltaic waterproof bracket, after the main beam 2 is installed, the plug rod 401 is pulled out, so that the plug rod 401 drives the limit block 402 to be received in the circular sub-groove inside the rectangular groove on the lower surface of the slider, and then the sliding block 301 is placed on the main beam 2. After the sliding block 301 is slid to a suitable position, the plug rod 401 is inserted through the sliding block 301 and the circular hole inside the main beam 2, so that the plug rod 401 drives the limit block 402 to pass through the main beam 2 from the side of the sliding block 301 close to the fixed block 404, and then the plug rod 401 is rotated to drive the limit block 402 to rotate in the fixed block 404, so that the circular hole inside the plug rod 401 and the circular hole inside the fixed block 404 are aligned. The holes are connected, so that the connecting pin 403 is inserted into the fixing block 404 and the plug rod 401 through the circular hole, and finally the sliding block 301 is fixed. After several sliding blocks 301 are installed on the main beam 2 in sequence through the above process, the guide plate 304 is pulled out, so that the two adjacent sliding blocks 301 are connected through the guide plate 304, and the connecting blocks 305 fixedly connected on the outer surfaces of the two guide plates 304 are connected. When connecting, the plug plate 308 is pulled out. When the two connecting blocks 305 are connected, the plug plate 308 is released. The plug plate 308 is retracted under the action of the connecting plate 307 and the tension spring 306, thereby driving the plug plate 308 to be inserted into the slot inside the other connecting block 305, so that two guides are connected. The two guide plates 304 are butted together. When the two guide plates 304 are butted together, the gaps at the butt joints of the two guide plates 304 are covered by the pressing plate 302, so that when it rains, when rainwater passes through the gaps of the two guide plates 304, it is diverted by the pressing plate 302, thereby preventing water leakage. After the sliding block 301 is installed, the crossbeam 1 is butted with the plug-in block 504, and the crossbeam 1 is plugged in through the slot inside the plug-in block 504. After the plug-in is completed, the plug-in parts of the crossbeam 1 and the plug-in block 504 are drilled by other tools, and then fixedly connected by bolts and nuts, and then the crossbeam 1 is inserted into the rectangular square on the side of the rotating block 508 and the sliding block 301 through the plug-in block 504 and the plug-in block 501. The crossbeam 1 is then placed downwardly in the gap between the grooves, so that the plug block 501 is pressed downwardly on the upper surface of the rotating block 508. At this time, the through groove inside the plug block 501 is docked with the card block 503, and the limit plate 505 is driven to contact the limit of the card block 503 by pressing the two push blocks 506. The card block 503 pops up under the action of the transverse spring 507, thereby clamping the plug block 501 to achieve the installation of the crossbeam 1. When the heights of the adjacent main beams 2 are different, the rotating block 508 and the rotating disk 502 are used to drive the crossbeam 1 to tilt, and finally complete the installation of the photovoltaic waterproof bracket, thereby achieving the installation of the photovoltaic bracket on a ground with certain undulations, driving the crossbeam 1 to tilt, and facilitating the installation of the photovoltaic bracket.
