Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel mounting frames, and particularly to a stable positioning and mounting device for rooftop photovoltaic panels. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panel components, a controller, and an inverter, and the main components are composed of electronic components; solar cells can be encapsulated and protected after being connected in series to form large-area solar cell components, and then combined with components such as a power controller to form a photovoltaic power generation device; photovoltaic power generation is a very environmentally friendly power generation method and is also a power generation method strongly advocated by the state. It is easy to install and can be used and installed in complex environments and terrains. In civil photovoltaic power generation, users fixedly install photovoltaic panels on walls and houses; in factories, in order to meet the electricity demand, some factories densely lay photovoltaic panels on the top of factory buildings. For the convenience of maintenance and installation, a reasonable gap needs to be set between every two to three rows of photovoltaic panels to facilitate maintenance and installation personnel to pass through or perform maintenance on the photovoltaic panels.

[0003] However, for the current traditional installation method of photovoltaic panels with high-density distribution requirements, the surface of the photovoltaic panel body is relatively fragile and is extremely likely to form scratches or breakages when subjected to external forces and cannot be stepped on. Therefore, when arranging photovoltaic panels, a reasonable gap needs to be set between every two to three rows of photovoltaic panels for maintenance and operation personnel to pass through. However, some users, in order to pursue the installation density of photovoltaic panels, closely arrange the photovoltaic panels. When maintaining the photovoltaic panels, they need to rely on ladders or step on the frames of the photovoltaic panels to maintain the inner photovoltaic panels, which is very likely to damage the stepped-on photovoltaic panels.

[0014] Beneficial effects

[0015] The photovoltaic panel mounting frame according to the embodiments of the present invention, compared with the traditional photovoltaic panel mounting frame, the internal connecting frame body of the photovoltaic panel is a movable frame body. After the panel is installed, the panel can still be moved. After the panel is adjusted, the structure of the internal frame body can be adjusted. The internal frame body hides a telescopic support assembly. Adjusting the expansion of the support assembly can install a standing plate or provide a support point for maintenance personnel.

[0016] In addition, through the cooperation of the lifting bolt lock and the loosening prevention lock plate, under normal conditions, the loosening prevention lock plate is inserted into the lock top tightening handles of the two mutually hinged lifting bolt locks at the same time to form a fixed connection, fixing the angles of the two lifting bolt locks, keeping the two photovoltaic panel bodies on both sides flat, effectively controlling the gap between adjacent photovoltaic panel bodies, and firmly fixing the photovoltaic panel bodies; when the loosening prevention lock plate is pulled out, the two lifting bolt locks and the photovoltaic panel bodies on both sides lose the angle limitation. Under the action of gravity and the two hinged lifting bolt locks, the middle of the two panels sinks, causing the two lifting bolt locks to rotate under the guiding action of the lock limit end shafts and the limit arc grooves, pushing the lifting adjustment bracket downward. The lifting adjustment bracket moves vertically downward under the guiding action of the vertical guiding square rod and the guiding square tube, making the two photovoltaic panel bodies on both sides form an inclined state. The outer edges of the two photovoltaic panel bodies on both sides move toward the middle under the action of the inclination of the panels, exposing the movable support columns and the lifting adjustment bracket below the positions of the outer edges of the two photovoltaic panel bodies on both sides.

[0017] In addition, through the cooperation of the movable strut and the lifting adjustment bracket, the movable strut is helically connected in the inner spiral groove. By inserting an external hexagonal rotating handle into the hexagonal rotating groove, the movable strut can be rotated to make the movable strut rise above the height of the photovoltaic panel body, which can be used to erect a support plate or as a temporary stepping frame, so as to repair and clean the photovoltaic panels located in the inner circle, avoiding the situation that when the traditional photovoltaic panels have too high distribution density, stepping on the outer circle photovoltaic panels is required for the repair or cleaning of the inner circle photovoltaic panels, which is likely to cause damage to the outer circle photovoltaic panels.

[0018] In addition, through the action of the outer support adjustment rotating frame and the movable strut, the outer support adjustment rotating frame is rotatably connected to the movable strut, and its axial positioning strength is enhanced through the limit shaft collar. After the movable strut rises, the outer support adjustment rotating frame can be rotated by ninety degrees, and then through the action of the positioning screw top groove and the tightening screw, the angle of the outer support adjustment rotating frame is fixed, which can improve the support stability of the movable strut.

[0037] In addition, according to an embodiment of the present invention, as Figure 9 shown, a groove is provided on both sides of the upper surface of the first positioning foot 3 respectively, and two parallel guide rods 301 are fixedly connected to the inner parts of the two grooves of the first positioning foot 3 respectively. The two parallel guide rods 301 are parallel to each other. A lifting guide cylinder 302 is fixedly connected to the middle of the upper surface of the first positioning foot 3. The lifting guide cylinder 302 is perpendicular to the upper surface of the first positioning foot 3, and an internal spiral groove 3021 is provided inside the lifting guide cylinder 302; the first positioning foot 3 is fixedly connected to the main frame body, and the parallel guide rods 301 are slidably connected to the translation guiding holes 601 to guide the translation support block 6; the internal spiral groove 3021 and the movable support column 4 form a spiral drive to realize the lifting and telescoping of the movable support column 4.

[0038] In addition, according to an embodiment of the present invention, as Figure 7 shown, the movable support column 4 is of a stud structure, and the movable support column 4 is spirally connected to the internal spiral groove 3021. A hexagonal groove structure of a hexagonal rotary groove 401 is provided in the middle of the upper end surface of the movable support column 4. A limiting shaft collar 402 is machined on the movable support column 4, and the limiting shaft collar 402 is located below the internal spiral groove 3021; the limiting shaft collar 402 is located below the outer support adjusting rotary frame 5 to improve the axial support force. By inserting an external hexagonal rotary handle into the hexagonal rotary groove 401, the movable support column 4 can be rotated to make the movable support column 4 rise to a height higher than that of the photovoltaic panel body 10, which can be used to erect a support plate or as a temporary stepping frame, so as to repair and clean the photovoltaic panels in the inner circle, avoiding the situation that when the distribution density of traditional photovoltaic panels is too high, stepping on the outer circle photovoltaic panels is required for the repair or cleaning of the inner circle photovoltaic panels, which is likely to cause damage to the outer circle photovoltaic panels.

[0039] In addition, according to an embodiment of the present invention, as Figure 9 shown, two auxiliary support frames 501 are fixedly connected to the lower surface of the outer support adjustment rotary frame 5. The two auxiliary support frames 501 are both perpendicular to the lower surface of the outer support adjustment rotary frame 5. Arc-shaped grooves are formed on the inner surfaces of the two auxiliary support frames 501. The arc-shaped grooves fit the outer surface of the lifting guide cylinder 302. And a positioning screw top groove 5011 with a screw hole structure is penetrated through the auxiliary support frame 501; under normal conditions, when the movable support column 4 is hidden, the outer support adjustment rotary frame 5 is parallel to the gap between the two plates, which is convenient for storage and hiding. When the movable support column 4 is unfolded, the outer support adjustment rotary frame 5 can be rotated by 90 degrees, and then through the action of the positioning screw top groove 5011 and the tightening screw, the angle of the outer support adjustment rotary frame 5 is fixed, effectively improving the support stability of the movable support column 4, increasing the artificial stepping area and the support plate erection area, and improving the smoothness during the manual maintenance process.

[0040] In addition, according to an embodiment of the present invention, as Figure 8 shown, a translation guide hole 601 with a circular hole structure is horizontally penetrated through the translation support block 6. And a rotary bolt lock 602 is hinged above the translation support block 6. The rotary bolt lock 602 is tightly connected to the outer frame of the photovoltaic panel body 10 through a bolt. The outer edges of the two photovoltaic panel bodies 10 on both sides move towards the middle under the action of the inclination of the plate body, so that the outer edge positions of the two photovoltaic panel bodies 10 on both sides move towards the direction of the lifting bolt lock 8. The outer edges of the photovoltaic panel body 10 slide smoothly on the first positioning foot 3 under the support of the translation support block 6 and the rotary bolt lock 602, and then the lower movable support column 4 and the lifting adjustment bracket 7 can be exposed.

[0041] In addition, according to an embodiment of the present invention, as Figure 5As shown in the figure, a vertical guiding square rod 701 is fixedly connected to the lower surface of the lifting and adjusting bracket 7. The vertical guiding square rod 701 is perpendicular to the lower surface of the lifting and adjusting bracket 7, and the vertical guiding square rod 701 is slidably connected to the rectangular groove of the guiding square cylinder 2; on the front side and the rear side of the upper surface of the lifting and adjusting bracket 7, a lifting balance support plate 702 is respectively fixedly connected. Two limiting arc grooves 7021 are formed in the lifting balance support plate 702. The limiting arc grooves 7021 are of an arc structure, and the centers of the limiting arc grooves 7021 are coaxial with the hinge shafts of the two lifting bolt latches 8. The fixed latch limiting end shaft 802 is slidably connected inside the limiting arc grooves 7021, which plays a role in guiding and limiting the rotation of the two lifting bolt latches 8; a latch top locking handle 801 is fixedly connected to the inner side of the upper surface of the lifting bolt latch 8. A rectangular groove body is formed in the latch top locking handle 801, and an anti-loosening lock plate 9 is tightly inserted into the rectangular groove body. The anti-loosening lock plate 9 is simultaneously inserted into the latch top locking handles 801 of the two mutually hinged lifting bolt latches 8 to form a fixed connection, fixing the angles of the two lifting bolt latches 8, keeping the two photovoltaic panel bodies 10 on both sides flat, effectively controlling the gap between adjacent photovoltaic panel bodies 10, and firmly fixing the photovoltaic panel bodies 10. At the front end and the rear end of the inner side below the lifting bolt latch 8, a fixed latch limiting end shaft 802 is respectively provided; when the anti-loosening lock plate 9 is pulled out, the two lifting bolt latches 8 and the photovoltaic panel bodies 10 on both sides lose the angle limitation. Under the action of gravity and the two hinged lifting bolt latches 8, the middle of the two panels sinks, causing the two lifting bolt latches 8 to rotate under the guiding action of the latch limiting end shaft 802 and the limiting arc grooves 7021, pushing the lifting and adjusting bracket 7 downward. The lifting and adjusting bracket 7 vertically moves downward under the guiding action of the vertical guiding square rod 701 and the guiding square cylinder 2.

[0042] Specific usage and function of this embodiment: In the present invention, under normal conditions, the anti-loosening lock plate 9 is inserted into the lock top locking handle 801 of two mutually hinged lifting bolt locks 8 at the same time to form a fixed connection, fixing the angles of the two lifting bolt locks 8, keeping the two photovoltaic panel bodies 10 on both sides in a straight state, effectively controlling the gap between adjacent photovoltaic panel bodies 10, and firmly fixing the photovoltaic panel bodies 10; when the anti-loosening lock plate 9 is pulled out, the two lifting bolt locks 8 and the photovoltaic panel bodies 10 on both sides lose the angle limit. Under the action of gravity and the two hinged lifting bolt locks 8, the middle of the two plate bodies sinks, causing the two lifting bolt locks 8 to rotate under the guiding action of the lock limit end shaft 802 and the limit arc groove 7021, pushing the lifting adjustment bracket 7 downward. The lifting adjustment bracket 7 moves vertically downward under the guiding action of the vertical guiding square rod 701 and the guiding square tube 2, making the photovoltaic panel bodies 10 on both sides form an inclined state. The outer edges of the photovoltaic panel bodies 10 on both sides move toward the middle under the action of the plate body inclination, exposing the movable support column 4 and the lifting adjustment bracket 7 below the outer edge positions of the photovoltaic panel bodies 10 on both sides. Insert an external hexagonal rotating handle into the hexagonal groove 401 to rotate the movable support column 4, making the movable support column 4 rise higher than the height of the photovoltaic panel body 10. After the movable support column 4 is unfolded, rotate the outer support adjustment rotating frame 5 by ninety degrees, and then fix the angle of the outer support adjustment rotating frame 5 through the positioning screw top groove 5011 and the tightening screw, effectively improving the support stability of the movable support column 4, increasing the artificial stepping area and the area for erecting the support plate, which can be used to erect the support plate or as a temporary stepping frame, so as to repair and clean the photovoltaic panels located in the inner circle, avoiding the situation that when the distribution density of traditional photovoltaic panels is too high, stepping on the outer circle photovoltaic panels during the repair or cleaning of the inner circle photovoltaic panels is likely to cause damage to the outer circle photovoltaic panels, and effectively improving the stability during the manual maintenance process.

[0043] Finally, it should be noted that when describing the positions of various components and their cooperation relationships, etc. in the present invention, usually one / a pair of components are taken as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. are equally applicable to other components / other pairs of components.
