Description

Technical Field

[0002] Since the main parts of the photovoltaic power generation system are installed in the open air and are distributed over a large area, there is a risk of direct and indirect lightning strikes. At the same time, the photovoltaic power generation system is directly connected to related electrical equipment and buildings, so lightning strikes on the photovoltaic system will also involve related equipment, buildings, and electrical loads.

[0011] Technical effects and advantages of the utility model:

[0012] 1. Because the first connector and the second connector are installed at both ends of the metal shell outside the photovoltaic panel, during installation, it is only necessary to connect the set assembly on one photovoltaic panel with the clamping assembly on the previous photovoltaic panel, and then connect the clamping assembly on one photovoltaic panel with the set assembly on the next photovoltaic panel to realize the grounding series connection between multiple photovoltaic panels, which is convenient for rapid installation. Due to weather and climate reasons, the photovoltaic panels occasionally need to adjust the installation layout. At this time, it is only necessary to disassemble the set assembly and the clamping assembly and connect them with the corresponding set assembly and clamping assembly on other photovoltaic panels. There is no need to remove the screws tediously, so that the layout of the photovoltaic panels can be changed and the rapid grounding between the photovoltaic panels can be completed without the help of tools, which reduces the workload of workers, increases work efficiency, and reduces installation time;

[0013] 2. Hold the first turning handle and the second turning handle with both hands respectively, then align the card block with the first card slot on the first set housing, and insert the card housing into the installation gap. At this time, the first set housing enters the first card slot. When waiting for it to be fully entered, the pressing ring is pushed into the installation slot, and then the card assembly is rotated. At this time, the card block enters the second card slot. When it is rotated to the point where it cannot be rotated, you can release your hands. At this time, the card block enters the third card slot under the push of the spring. Because the spring is in a compressed state, the card block will be firmly stuck in the third card slot. The set assembly and the card assembly can be installed by pushing and turning. When disassembling, press the card assembly and then turn it in the opposite direction to pull out the card assembly. The set assembly and the card assembly can be disassembled by pressing and turning, which further reduces the workload of workers, further improves work efficiency, and reduces the total engineering time.

[0014] 3. When the sleeve assembly and the card assembly are installed, the card-jointed shell is carded into the installation gap. At this time, the card-jointed shell and the second sleeve shell form a Faraday cage, which accommodates the first conductive ring and the second conductive ring inside, avoiding the discharge of the first conductive ring and the second conductive ring due to poor contact due to external reasons, and avoiding the safety hazard caused by discharge due to poor contact. The first conductive ring and the second conductive ring are staggered. When the card-jointed shell enters the installation gap, the first conductive ring is just carded inside the second conductive ring, which increases the contact area between the first conductive ring and the second conductive ring, thereby increasing the conductive effect at the joint and reducing the occurrence of poor contact.

[0015] 4. Because photovoltaic panels are mostly installed outdoors, sand and gravel are likely to appear inside the device, which may create the illusion that the block is blocked by the sand and gravel and cause the installation to be in place. By setting a warning block and a limit block, when the block enters the third slot, the block pushes the limit block and the warning block to move up. At this time, the upper end of the warning block extends out of the slide slot, and the worker can observe that the warning block is extended, which means that the device is installed in place. When the warning block does not extend out of the slide slot, it means that the installation is not in place and needs to be readjusted until the warning block extends out of the slide slot. In particular, the upper end of the warning block can be painted with red paint to warn the installer whether it is installed in place, and then know whether the photovoltaic panel is successfully grounded.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-6 A device for grounding a photovoltaic power generation component is shown, comprising a sleeve component 1 and a clamping component 2, a first conductor 3 is fixedly installed on one side of the sleeve component 1, a first connector 5 is fixedly installed on the side of the first conductor 3 away from the sleeve component 1, a clamping component 2 is provided on the side of the sleeve component 1 away from the first conductor 3, a second conductor 4 is fixedly installed on the side of the clamping component 2 away from the sleeve component 1, a second connector 6 is fixedly installed on the side of the second conductor 4 away from the clamping component 2, the second conductor 4 is fixedly installed on one side of a metal shell of a photovoltaic panel, the second connector 6 is fixedly installed on the shell of the photovoltaic panel away from the first connector 5, and the sleeve component 1 and the clamping component 2 on an adjacent photovoltaic panel are detachably installed.

[0025] Because the first connector 5 and the second connector 6 are installed at both ends of the metal shell outside the photovoltaic panel, during installation, it is only necessary to connect the sleeve component 1 on one photovoltaic panel with the clamping component 2 on the previous photovoltaic panel, and then connect the clamping component 2 on one photovoltaic panel with the sleeve component 1 on the next photovoltaic panel to achieve the grounding series connection between multiple photovoltaic panels, which facilitates quick installation. Due to weather and climate reasons, the photovoltaic panels occasionally need to adjust the installation layout. At this time, it is only necessary to disassemble the sleeve component 1 and the clamping component 2 and connect them with the corresponding sleeve components 1 and clamping components 2 on other photovoltaic panels. There is no need for tedious removal of screws, so that the changes to the photovoltaic panel layout and the quick grounding between photovoltaic panels can be completed without the help of tools, reducing the workload of workers, increasing work efficiency, and reducing installation time.

[0026] The sleeve assembly 1 includes a first sleeve housing 11, a second sleeve housing 12 is fixedly installed in the middle position of the first sleeve housing 11, an installation gap 14 exists between the first sleeve housing 11 and the second sleeve housing 12, a multi-layer first conductive ring 13 is arranged inside the second sleeve housing 12, the first conductive ring 13 is fixedly installed inside the first sleeve housing 11, a plurality of first card slots 101 are opened at the open end of the first sleeve housing 11, and a plurality of slide slots 101 corresponding to the first card slots 101 are opened at one end of the outer ring of the first sleeve housing 11 4, a first turning handle 15 is fixedly installed at the outer ring of the first sleeve housing 11 away from the first slot 101, a first rubber head 16 is fixedly installed at the end of the first sleeve housing 11 away from the first slot 101, and the middle part of the first rubber head 16 is fixedly installed at the end of the first wire 3 away from the first connector 5, and the clamping assembly 2 includes a clamping housing 21, and a mounting groove 24 is opened at the opening of the clamping housing 21, and a pressing ring 22 is slidably installed inside the mounting groove 24, and a spring 25 is arranged inside the mounting groove 24, and both ends of the spring 25 are respectively fixedly installed Mounted on the pressing ring 22 and the mounting groove 24, a multi-layer second conductive ring 23 is fixedly installed at the middle position of the inner part of the snap-fit ​​housing 21, the first conductive ring 13 and the second conductive ring 23 are arranged alternately, a plurality of clamping blocks 26 corresponding to the first clamping groove 101 are fixedly installed at the outer ring of the snap-fit ​​housing 21, and a second clamping groove 102 and a third clamping groove 103 corresponding to the first clamping groove 101 are opened at the inner ring of the first sleeve housing 11, the second clamping groove 102 is connected to the first clamping groove 101, and the third clamping groove 103 is connected to the second clamping groove 102 and the slide groove 104. The first card slot 101, the second card slot 102, and the third card slot 103 are all connected to the installation gap 14, the slide slot 104 is connected to the outside of the first sleeve shell 11, the card block 26 is slidably carded inside the first card slot 101, the second card slot 102, and the third card slot 103, and the second turning handle 27 is fixedly installed on the outer ring of the card shell 21 away from the pressing ring 22, and the second rubber head 28 is fixedly installed on the end of the card shell 21 away from the opening end, and the middle part of the second rubber head 28 is fixedly installed on the end of the second wire 4 away from the second connector 6.

[0027] When in actual use, hold the first turning handle 15 and the second turning handle 27 with both hands respectively, then align the clamping block 26 with the first clamping groove 101 on the first sleeve shell 11, and insert the clamping shell 21 into the installation gap 14. At this time, the first sleeve shell 11 enters the first clamping groove 101. When waiting to be fully entered, the pressing ring 22 is pushed into the installation groove 24, and then the clamping component 2 is rotated. At this time, the clamping block 26 enters the second clamping groove 102. When it is rotated until it cannot be rotated, both hands can be released. At this time, the clamping block 26 enters the third clamping groove 103 under the push of the spring 25. Because the spring 25 is in a compressed state, the clamping block 26 will be firmly stuck in the third clamping groove 103. The sleeve component 1 and the clamping component 2 can be installed by pushing and turning. When disassembling, press the clamping component 2 and then rotate it in the opposite direction to pull out the clamping component 2.

[0028] Furthermore, when the sleeve component 1 and the clamping component 2 are installed, the clamping shell 21 is clamped into the interior of the installation gap 14. At this time, the clamping shell 21 and the second sleeve shell 12 form a Faraday cage, which accommodates the first conductive ring 13 and the second conductive ring 23 inside, avoiding the discharge of the first conductive ring 13 and the second conductive ring 23 due to poor contact due to external reasons, and avoiding the safety hazard caused by discharge due to poor contact. The first conductive ring 13 and the second conductive ring 23 are staggered. When the clamping shell 21 enters the interior of the installation gap 14, the first conductive ring 13 is just clamped inside the second conductive ring 23, which increases the contact area between the first conductive ring 13 and the second conductive ring 23, thereby increasing the conductive effect at the joint and reducing the occurrence of poor contact.

[0029] A warning block 111 is provided inside the sliding slot 104, and a limit block 112 is fixedly installed on the bottom end of the warning block 111. The limit block 112 is slidably carded inside the third slot 103. Both sides of the warning block 111 and the limit block 112 are designed with inclined surfaces and the inclined height is the height of the third slot 103.

[0030] Because photovoltaic panels are mostly installed outdoors, sand and gravel are easily present inside the device, which may create the illusion that the block 26 is blocked by the sand and gravel and cause the illusion that the installation is in place. By setting the warning block 111 and the limit block 112, when the block 26 enters the third slot 103, the block 26 pushes the limit block 112 and the warning block 111 to move upward. At this time, the upper end of the warning block 111 extends out of the slide slot 104. The worker can observe that the warning block 111 is extended, which indicates that the device is installed in place. When the warning block 111 does not extend out of the slide slot 104, it means that the installation is not in place and needs to be readjusted and installed until the warning block 111 extends out of the slide slot 104. In particular, the upper end of the warning block 111 can be painted with red paint to warn the installer whether the installation is in place, and then know whether the photovoltaic panel is successfully grounded.
