Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic equipment installation, and more specifically, to a photovoltaic grounding buckle. Background Art
[0002] A photovoltaic grounding buckle is a lightning protection and grounding accessory for a solar photovoltaic system. Its main function is to establish a reliable electrical connection between a photovoltaic module and a support system, ensuring that lightning strike current can be quickly transmitted to the ground, thereby protecting the entire photovoltaic system from lightning damage.
[0003] The grounding buckles in the prior art generally consist of two connecting rings and a section of wire in the middle. The two connecting rings are respectively used to connect the support and the ground component. However, due to the fixed length of the wire, when the support is at a high position, multiple sections of grounding buckles often need to be connected end to end to achieve connection with the ground. During this process, clips or screws and nuts are required for fixation. However, since the screws, nuts or clips themselves need to be conductive, there will inevitably be a phenomenon of electric leakage during the conduction process, which will have an adverse impact on the photovoltaic equipment.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model
[0005] The purpose of the utility model is to provide a photovoltaic grounding buckle to solve the above problems.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A photovoltaic grounding buckle includes two connecting rings, and each connecting ring is connected with a section of wire. The two ends of the wire are fixed through a connecting sleeve. A ring slicer is arranged in the connecting sleeve, and the ring slicer is used for cutting the rubber skin of the wire.
[0007] The utility model is further arranged as: Three rotating sleeves are threadedly connected to the connecting sleeve, and the ring slicer is arranged inside the middle rotating sleeve.
[0008] The utility model is further arranged as: The lengths of the rotating sleeves on both sides are less than the length of the middle rotating sleeve.
[0009] The utility model is further arranged as: The connecting sleeve is made of rubber, and sealing closures are arranged on the connecting sleeves on both sides.
[0010] The utility model is further arranged as: An insulating sleeve is further arranged at the connection between the connecting ring and the wire, and a jack for connecting with another wire is opened on the insulating sleeve.
[0011] The utility model is further arranged as: A fixing ring is arranged on the insulating sleeve.
[0012] In summary, the utility model has the following beneficial effects:
[0013] The two ends of the wire are connected by a connecting sleeve. When the rotating sleeve rotates, the ring slicer will be driven to cut the rubber sheath of the wire and directly contact the copper wire inside, thus playing the role of connecting the two ends of the wire. During this process, the overall length of the grounding buckle can be flexibly selected between 1 to 2 times the wire length without the need to rely on other accessories. Since the connecting sleeve is made of rubber material and completely wraps the connection, it can also greatly avoid the occurrence of leakage, ensuring the normal use of the photovoltaic equipment.

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] The photovoltaic grounding buckle, as Figure 1 and Figure 2 shown, includes two connecting rings 1. Each connecting ring 1 is connected with a section of wire 2. The two ends of the wire 2 are fixed by a connecting sleeve 3. A ring slicer 4 is arranged inside the connecting sleeve 3. The ring slicer 4 is used to cut the rubber sheath of the wire 2. The two connecting rings 1 are respectively used to connect the photovoltaic bracket and the grounding component, and thus can conduct electricity by connecting the two sections of wire 2, guiding the current on the bracket to the grounding component and then leading it into the ground, thereby ensuring the normal use of the photovoltaic equipment. The ring slicer 4 is used to cut open the rubber sheath between the two sections of wire 2, and then use its own metal material to make the two sections of wire 2 electrically connected to achieve a complete conductive function. The connecting sleeve 3 is used to provide insulation protection for the connection to prevent leakage of the wire 2 during use and further improve safety.
[0019] Three rotating sleeves 5 are threadedly connected to the connecting sleeve 3. The annular slicer 4 is arranged inside the middle rotating sleeve 5. The lengths of the rotating sleeves 5 on both sides are less than the length of the middle rotating sleeve 5. The rotating sleeve 5 is used to drive the annular slicer 4 to perform spiral cutting with the wire 2 as the axis, so as to ensure that the annular slicer 4 fully cuts the rubber sheath, and then the function of connecting two sections of wire 2 can be realized. The rotating sleeve 5 with a larger length can not only give the annular slicer 4 enough distance for cutting, but also play an adequate insulation protection role for the connection part, further preventing the occurrence of electric leakage. The connecting sleeve 3 is made of rubber, and sealing closures are arranged on the connecting sleeves 3 on both sides. The rubber material and the sealing closures can be used to further strengthen the insulation of the ends of each section of wire 2, further preventing electric leakage.
[0020] An insulating sleeve 6 is also arranged at the connection between the connecting ring 1 and the wire 2. An insertion hole for connecting with another wire 2 is opened on the insulating sleeve 6. A fixing ring is arranged on the insulating sleeve 6. This setting ensures a greater degree of insulation for the end of the wire 2 close to the connecting ring 1, and thus the safety can be improved.
[0021] Working principle: When the length of a section of wire 2 is sufficient, the free ends of the wire 2 can be respectively inserted into the insertion holes of another wire 2, and then the fixing ring is rotated. The fixing ring has the same structure as the connecting sleeve 3 and can play the same role as the annular slicer 4, so that the two sections of wire 2 are connected and thus function. And because the grounding buckle is equivalent to an increased diameter at this time, the resistance will decrease, the power transmission will increase, and thus the current that can be guided is stronger, so the protection ability for the photovoltaic device is also stronger;
[0022] When the length of a section of wire 2 is insufficient, first place the two sections of wire 2 staggeredly according to the required length, then fasten the connecting sleeve 3, rotate the rotating sleeves 5 on both sides to fix the two sections of wire 2, and then rotate the middle rotating sleeve 5 to cut the rubber sheath with the annular slicer 4, so as to connect the point connection between the two sections of wire 2 and achieve a complete effect.
[0023] In summary, the utility model can not only obtain a better protection effect when the length is sufficient, but also be flexibly adjusted when the length is insufficient to meet the length requirements. And because the connection part is completely wrapped and no additional tools and accessories are needed, the safety and convenience are also improved to a certain extent.
[0024] The above is only the preferred embodiment of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions falling within the idea of the utility model belong to the protection scope of the utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the utility model, several improvements and refinements should also be regarded as the protection scope of the utility model.
