Description
Technical field
The utility model belongs to the mounting technique field of photovoltaic module, particularly a kind of photovoltaic component frame earthing device.
Background technology
Solar photovoltaic assembly has requirement to ground connection when mounted usually.Because the frame of photovoltaic module mostly adopts the aluminium frame, there are oxide layer or coating layer in the surface of aluminium frame, and this oxide layer or coating layer are nonconducting, might cause this aluminium frame imperfect earth.So, when the photovoltaic system of grounding requirement is installed, need manage to destroy this oxide layer or coating layer, the effective grounding of guarantee photovoltaic module.Some solutions are welding or set up earth connection, so both increase the difficulty of installation, and needing increases extra parts, brings cost pressure, reduces installation effectiveness.
The utility model content
Technical problem to be solved in the utility model is, a kind of simple in structure and photovoltaic component frame earthing device that can reliable ground is provided.
the utility model is to realize like this, a kind of photovoltaic component frame earthing device is provided, can be fixed on adjacent two photovoltaic component frames, it comprises ground strip, briquetting and securing member, described briquetting and ground strip are arranged on the top of photovoltaic component frame, described ground strip is arranged between described briquetting and photovoltaic component frame, described securing member can be pressed on described briquetting and ground strip on described photovoltaic component frame, described ground strip comprises main flat board and some sawtooth sheets, at the described main dull and stereotyped middle notch that is provided with, described notch is provided with opening, described opening is arranged on a described main dull and stereotyped side and connects with described notch, described sawtooth sheet is separately positioned on the both sides of the edge of described opening, and described sawtooth sheet is connected with main dull and stereotyped one, and exceeds the upper and lower surface of described main flat board.
Further, the corner at the close described opening part of described main dull and stereotyped front end is arc chord angle.
Further, the width of described opening and notch is a bit larger tham the width of described securing member.
Further, described ground strip is made by metal conductive materials.
Further, convex with the tongue limit at the top of described briquetting, described tongue limit is positioned at the dual-side of described briquetting and outwards extends, and described tongue limit can be fitted on photovoltaic component frame, and described sawtooth sheet just in time is positioned at the below on described tongue limit.
Compared with prior art, photovoltaic component frame earthing device of the present utility model can be fixed on adjacent two photovoltaic component frames.After the utility model was installed, the some sawtooth sheets on ground strip can puncture the diaphragm on photovoltaic component frame surface, make adjacent two photovoltaic component frames realize reliable grounding connection.Earthing mode of the present utility model is simple in structure, both can install together with briquetting, also can be installed separately with briquetting, uses more flexibly, and need not to increase bolt, nut, improves installation effectiveness.

Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Please refer to shown in Figure 1, the schematic perspective view of photovoltaic component frame earthing device embodiment of the present utility model.The utility model is fixed on adjacent two photovoltaic component frame A, and it comprises ground strip 1, briquetting 2 and securing member 3.Briquetting 2 and ground strip 1 are arranged on the top of photovoltaic component frame A, and ground strip 1 is arranged between briquetting 2 and photovoltaic component frame A, and securing member 3 can be pressed on briquetting 2 and ground strip 1 on photovoltaic component frame A.
Because ground strip 1 one sides are provided with opening 14, and the width of opening 14 and notch 13 is a bit larger tham the width of securing member, and therefore, when the utility model was installed, ground strip 1 can not installed with briquetting 2 and securing member 3.Before securing member 3 screwed, ground strip 1 can be inserted between briquetting 2 and photovoltaic component frame A from a side of briquetting 2.Because opening 14 can pass securing member 3 by a side of briquetting 2, make ground strip 1 can be arranged on briquetting 2 under, increased applicability of the present utility model, more flexible during use.Simultaneously, for the ease of inserting, be set to arc chord angle at main dull and stereotyped 11 front ends of ground strip 1 near the corner 17 and 18 at opening 14 places, reduce the obstruction that runs into when ground strip 1 inserts.
Convex with tongue limit 21 at the top of briquetting 2, tongue limit 21 is positioned at the dual-side of briquetting 2 and outwards extends, and tongue limit 21 can be fitted on photovoltaic component frame A, and sawtooth sheet 12 just in time is positioned at the below on tongue limit 21.
Form the grounding connection of conduction for the parts that are in contact with it, in the present embodiment, ground strip 1 is made by metal conductive materials.The some sawtooth sheets 12 that are positioned at ground strip 1 both sides can puncture the surface protection film of photovoltaic component frame A; ground strip 1 can directly contact with the ground of photovoltaic component frame A; reduce the contact resistance of junction, make adjacent two photovoltaic component frame frame A realize that reliable conductive earthing connects.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
