Lap joint structure of solar photovoltaic module

Technical Field

The utility model relates to a solar PV modules technical field specifically is a solar PV modules's overlap joint structure.

Background

Solar photovoltaic modules are the core components of photovoltaic systems, and in the prior art, solar panels are usually packaged in frames for convenient installation. When there is a large power demand, a plurality of solar photovoltaic modules are connected in a splicing manner to form a large-area solar array. However, in the prior art, the fixing connection is usually realized through screws and the like, so that the defects of inconvenient installation and low installation efficiency exist.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a solar PV modules's overlap joint structure has solved the problem that inconvenient, the installation effectiveness is low of installation when solar PV modules jogged joint.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

a lap joint structure of a solar photovoltaic module comprises a back plate; a pair of side edges of the back plate are symmetrically bent into folded edges with clamping grooves respectively and are used for buckling and connecting with adjacent components; when the locking is carried out, the outside of the clamping groove at one side of one assembly is clamped into the inside of the clamping groove at the other side of the adjacent assembly.

As a further improvement of the utility model, the folded edge is an open polygon.

As a further improvement of the utility model, the cross-sectional shape of the hem is: the top of the trumpet-shaped inlet is connected with a hexagon with an opening at the bottom edge.

As a further improvement of the utility model, the support is further included, and the support includes: the two ends of the bottom plate are provided with through holes; the connecting plate is vertically and fixedly connected in the middle of the bottom plate; the top end matched with the clamping groove and the bottom of the top end are fixedly connected with the connecting plate.

As a further improvement of the utility model, the top is trapezoidal.

As a further improvement, the backboard is made of metal plate or non-metal plate.

The utility model discloses a frame is saved to solar PV modules's overlap joint structure, directly processes into the overlap joint structure with the side of backplate, and during the overlap joint, only need down press just can make adjacent subassembly lock link together, and the installation is simple; adopt the fixing support to support after the overlap joint, fix the support on steel construction purlins such as house during the installation, go into the draw-in groove of solar PV modules's overlap joint structure with support head card in, outside sclausura fixed mode is realized to entire system array, has avoided using the fixed problem of leaking that causes of outside trompil such as screw.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a solar PV modules's overlap joint structure, including backplate 1, as shown in fig. 1, a pair of side of backplate 1 is the hem 2 that has the draw-in groove of buckling into respectively symmetrically for be connected with adjacent subassembly lock, during the lock, the inside of adjacent subassembly opposite side draw-in groove is gone into to the outside card of a set of subassembly one side draw-in groove, as shown in fig. 3. The folds 2 are preferably open polygons such as triangles, quadrilaterals or hexagons; more preferably, the cross-sectional shape of the flange 2 is: the top of the flared inlet is connected with a hexagon with an open bottom edge, as shown in fig. 2.

In an embodiment, as shown in fig. 4, the overlapping structure of the solar photovoltaic module further includes a support 3, and the support 3 includes: a bottom plate 31, a connecting plate 32, and a top end 33 that fits into the card slot; through holes are formed at two ends of the bottom plate 31; the connecting plate 32 is vertically and fixedly connected in the middle of the bottom plate 31; the bottom of the top end 33 is fixedly connected to the connecting plate 32. Preferably, the top end 33 is trapezoidal in shape and cooperates with a slot in the flange 2 in the shape of an open hexagon, as shown in fig. 5.

In the embodiment, the material of the back plate 1 may be a metal plate or a non-metal plate in the prior art, as long as the back plate can be bent to form a folded edge meeting the requirement.

In the embodiment, when the solar photovoltaic modules are lapped, the left and right adjacent modules can be buckled and connected together only by pressing downwards, the modules are combined more tightly, and the multi-bending type pressure carrying capacity is stronger; when the solar photovoltaic modules are vertically lapped, the bottom edge part of the solar photovoltaic module positioned above is lapped on the top edge of the solar photovoltaic module positioned below and is finally bonded together through a T-shaped adhesive. Adopt the fixing support to support after the overlap joint, pass through the through-hole of bottom plate with the support during installation and fix on steel construction purlins such as house, go into the draw-in groove of solar PV modules's overlap joint structure with support top card for whether control or all can not produce the slip from top to bottom between the lapped solar PV modules, outside sclausura fixed mode is realized to the entire system array, has avoided using the fixed problem of leaking that causes of outside trompil such as screw. The installation mode is simple, the whole system is in seamless connection, the combination is tight, no hole exists outside, no fasteners such as screws are arranged, and the waterproof performance is better.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
