Description

Technical Field

[0001] This utility model belongs to the field of new energy technology, specifically relating to a photovoltaic panel docking device. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three parts: photovoltaic panels, controllers, and inverters.

[0003] A photovoltaic panel is a power generation device that generates direct current when exposed to sunlight. It consists of thin, solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0004] Photovoltaic panels need to be fixed to the ground using photovoltaic (PV) brackets. A PV bracket typically includes a support frame and sliding rails. After the PV panel is placed on the rails, a connection assembly is used to secure it to the bracket. Currently, PV panel connection assemblies generally refer to medium-voltage blocks, which are mainly used for connecting two PV panels.

[0005] Existing intermediate pressure blocks generally include a connecting plate and a screw. Pressure plates are symmetrically fixed on both sides of the connecting plate. The screw passes through the connecting plate, with one end of the screw being a screw head and the other end of the screw threadedly connected to a clamping block. When installing photovoltaic panels, the lower end of the screw and the clamping block are placed inside the slide rail, and then the pressure plates are used to press the edge of the photovoltaic panel. Subsequently, the screw head is rotated until the pressure plates press the photovoltaic panel firmly, thereby fixing the photovoltaic panel. That is, when installing or removing photovoltaic panels, the screw head needs to be rotated many times, which is cumbersome and has low efficiency. Utility Model Content

[0020] In one possible implementation of the photovoltaic panel docking device provided by this utility model, the bottom of the push block is provided with a roller, and the roller is adapted to be engaged in the slot on the end face of the base.

[0021] The beneficial effects of the photovoltaic panel docking device provided by this utility model are as follows: Compared with the prior art, the photovoltaic panel docking device provided by this utility model, by rotating the push base, allows the bottom of the push block of the push base to slide along the inclined surface on the upper side of the base into the slot on the end face, increasing the total height of the base and the push base, thereby squeezing the spring and the pressure plate, so that the pressure plate applies pressure to the photovoltaic panel and completes the fixed installation of the photovoltaic panel; by rotating the push base, the push block is disengaged from the slot and slides down along the inclined surface, reducing the total height of the base and the push base, reducing the compression of the spring, thereby reducing the pressure applied by the pressure plate to the photovoltaic panel, loosening the photovoltaic panel, and allowing it to be disassembled, which is convenient for disassembly and assembly and greatly improves the efficiency of disassembly and assembly.

[0037] Please refer to the following: Figures 1 to 3 The photovoltaic panel docking device provided by this utility model will now be described. The photovoltaic panel docking device includes a clamping plate 10, a limiting guide rod 20, a pressure plate, a base 40, a push seat 50, and a spring 60. The clamping plate 10 is adapted to slide within the slide rail of the mounting frame; the lower end of the limiting guide rod 20 is connected to the clamping plate 10; the pressure plate is located on the upper side of the clamping plate 10 and is sleeved on the limiting guide rod 20, and the pressure plate is adapted to press against the upper side of two adjacent photovoltaic panels; the base 40 is located on the upper side of the pressure plate and connected to the pressure plate. The base 40 has a ring structure and is adapted to surround the limiting guide rod 20. The upper side is provided with an inclined surface 41 and an end face 42, and the end face 42 is provided with a slot 43; the push seat 50 has a ring structure and is suitable for surrounding the limiting guide rod 20 and being located on the upper side of the base 40. The push seat 50 extends downward to push block 51. The push seat 50 is suitable for rotating relative to the base 40, so that the bottom of the push block 51 slides along the inclined surface 41 into the slot 43 of the end face 42; the spring 60 is located on the upper side of the push seat 50 and is sleeved on the limiting guide rod 20. The lower end abuts against the push seat 50 and the upper end is connected to the limiting guide rod 20.

[0038] Specifically, the limiting guide rod 20 is fixedly connected to the clamping plate 10, which can be welded or screwed together; the base 40 is fixedly connected to the pressure plate, which can be snapped or welded together; the push seat 50 has a protrusion on its side to facilitate rotation. The upper side of the base 40 has two inclined surfaces 41 and end faces 42 that are respectively connected to the two inclined surfaces 41, and the two inclined surfaces 41 are symmetrically arranged. Therefore, by rotating the push seat 50 by no more than 180 degrees, the push block 51 can be inserted into the clamping groove 43 to fix the photovoltaic panel; or the push block 51 can be slid down along the inclined surface 41 to release the photovoltaic panel.

[0039] It should be noted that when installing photovoltaic panels, first align the edge of the photovoltaic panel with the slide rail on the mounting frame. Then, place the docking device into the slide rail. At this time, the clamping plate 10 is placed in the slide rail, and the pressure plate is placed on the upper part of the photovoltaic panel. After sliding the docking device to the required position, rotate the push base 50 to make the push block 51 slide into the slot 43 along the inclined surface 41, which will compress the spring 60 and apply pressure to the pressure plate or increase the pressure on the pressure plate, so that the pressure plate presses the photovoltaic panel, completing the fixing and installation of the photovoltaic panel. Then, make the bottom of the push block 51 disengage from the slot 43, rotate the push base 50, and make the push block 51 slide down along the inclined surface 41 to reduce the compression of the spring 60, which will reduce the pressure of the pressure plate on the photovoltaic panel. After that, the docking device can be slid to the misalignment position with the photovoltaic panel, and the photovoltaic panel can be removed.

[0040] The advantages of the photovoltaic panel docking device provided by this utility model are as follows: Compared with the prior art, the photovoltaic panel docking device provided by this utility model, by rotating the push base 50, causes the bottom of the push block 51 of the push base 50 to slide along the inclined surface 41 on the upper side of the base 40 into the slot 43 of the end face 42, increasing the total height of the base 40 and the push base 50, thereby squeezing the spring 60 and the pressure plate, so that the pressure plate applies pressure to the photovoltaic panel, completing the fixed installation of the photovoltaic panel; by rotating the push base 50, the push block 51 is disengaged from the slot 43 and slides down along the inclined surface 41, reducing the total height of the base 40 and the push base 50, reducing the compression of the spring 60, thereby reducing the pressure applied by the pressure plate to the photovoltaic panel, loosening the photovoltaic panel, and thus disassembling the photovoltaic panel; without needing to rotate the push base 50 multiple times, it can greatly improve the disassembly and assembly efficiency.

[0041] like Figure 1 As shown, in a specific embodiment of the photovoltaic panel docking device provided in this utility model, the pressure plate includes a groove plate 31 and two wing plates 32. The opening of the groove plate 31 is arranged facing upward, and the two wing plates 32 are respectively arranged on both sides of the groove plate 31 and connected to the upper end of the groove plate 31 to press and cover the two photovoltaic panels respectively.

[0042] It should be noted that the side of the groove plate 31 abuts against the side of the photovoltaic panel, restricting the lateral displacement of the photovoltaic panel, that is, the displacement in the direction parallel to the mounting surface of the mounting frame; the two wing plates 32 press against the upper side of the photovoltaic panel to restrict the displacement of the photovoltaic panel in the direction perpendicular to the mounting surface.

[0043] like Figure 1 As shown, in a specific embodiment of the photovoltaic panel docking device provided in this utility model, the pressure plate further includes two buffer pads 33, which are respectively disposed on the lower side of the two wing plates 32 and are attached and connected to the wing plates 32.

[0044] Specifically, in one embodiment of the photovoltaic panel docking device provided in this utility model, the buffer pad 33 is made of rubber, and the bottom of the buffer pad 33 is provided with anti-slip texture. Alternatively, the buffer pad 33 can also be made of a softer material such as silicone.

[0045] It should be noted that photovoltaic panels are relatively fragile. Therefore, a rubber buffer pad 33 is placed under the wing plate 32 to effectively prevent the wing plate 32 from damaging the photovoltaic panel. Furthermore, anti-slip textures are set on the underside of the buffer pad 33 to effectively increase friction and make the photovoltaic panel more securely fixed and less prone to shaking.

[0046] like Figure 1 As shown, in a specific embodiment of the photovoltaic panel docking device provided in this utility model, an adjusting bolt is also included. The upper part of the limiting guide rod 20 is provided with a threaded section. The adjusting bolt abuts against the upper end of the spring 60 and is threadedly engaged with the threaded section of the limiting guide rod 20.

[0047] Specifically, by turning the adjusting bolt, the compression of the spring 60 can be adjusted, and thus the pressure of the spring 60 on the pressure plate, i.e. the pressure of the pressure plate on the photovoltaic panel, can be adjusted as needed.

[0048] like Figure 1 As shown, in a specific embodiment of the photovoltaic panel docking device provided in this utility model, a limiting member is further included. A first limiting groove 21 is axially formed on the side of the threaded section of the limiting guide rod 20, and a second limiting groove 71 is axially formed on the inner side of the adjusting bolt. The lower end of the second limiting groove 71 passes through the adjusting bolt. The adjusting bolt is adapted to align the first limiting groove 21 and the second limiting groove 71 by rotation. The limiting member is adapted to be inserted into the aligned first limiting groove 21 and second limiting groove 71. The number of first limiting grooves 21 and second limiting grooves 71 can be one or more. When there are multiple first limiting grooves 21 or second limiting grooves 71, they need to be spaced circumferentially.

[0049] Specifically, such as Figure 1As shown, in a specific embodiment of the photovoltaic panel docking device provided in this utility model, there is one first limiting groove 21 and one to ten second limiting grooves 71, specifically four second limiting grooves 71; the limiting member includes a limiting plate 82 and a flexible connector 81, the limiting plate 82 is adapted to be engaged in the aligned first limiting groove 21 and second limiting groove 71, one end of the flexible connector 81 is connected to the limiting plate 82, and the other end is connected to the limiting guide rod 20 or the adjusting bolt.

[0050] It should be noted that the flexible connector 81 is made of nylon rope, chain, etc. One end of the flexible connector 81 is connected to the end of the limiting guide rod 20, and the other end is connected to the limiting plate 82 to effectively prevent the limiting plate 82 from being lost. After adjusting the compression of the spring 60 to the required value by rotating the adjusting nut 70, fine-tune the adjusting nut 70 to align the first limiting groove 21 and the second limiting groove 71. Then, insert the limiting plate 82 into the second limiting groove 71 to restrict the rotation of the adjusting nut 70 and prevent the adjusting nut 70 from rotating on its own, which could lead to the photovoltaic panel loosening.

[0051] like Figure 1 and Figure 2 As shown, in a specific embodiment of the photovoltaic panel docking device provided in this utility model, the bottom of the push block 51 is provided with a roller 52, which is adapted to be locked in the slot 43 of the end face 42 of the base 40, so as to facilitate the rotation of the push block 50 and reduce wear.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
