Description

Photovoltaic support staple bolt

Technical Field

The utility model relates to a be applied to solar photovoltaic support and support, fixed photovoltaic support staple bolt.

Background

The hoop is an important part for connecting and supporting the photovoltaic module system, which is commonly used by the single-upright-column tubular pile or the spiral tubular pile. The traditional hoop body is generally formed by bending a flat plate into a semicircle, has a simple structure, is easy to slide and loosen, is easy to crack after being stressed, and particularly can cause serious accidents of instability or collapse of a photovoltaic bracket system caused by stress fracture of the hoop body in extremely severe weather and environment. To solve the above problems, there are generally two ways: 1. the pre-tightening force during connection is increased by increasing the thickness of the metal plate, so that the cost is increased; 2. the mode of welding the reinforcing ribs is utilized to improve the rigidity and the strength of the reinforcing ribs, so that the working procedures are increased, and the processing difficulty is improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a photovoltaic support staple bolt rational in infrastructure, connect stable, antiskid, that intensity is higher to satisfy rigidity and the intensity demand of photovoltaic mounting structure system in mountain region and the extreme adverse circumstances photovoltaic power plant of the surface of water.

The photovoltaic bracket hoop comprises two hoop bodies connected through bolts, wherein each hoop body is integrally formed by an arc-shaped section in the middle and straight plate sections at two ends, and the straight plate sections are provided with bolt holes for bolts to pass through; the key point is that one or more reinforcing convex ribs protruding outwards are formed on the arc-shaped section in a stamping mode, and the reinforcing convex ribs extend along the length direction of the arc-shaped section; the position that the arc-shaped section meets with the straight plate section is formed with the enhancement convex part through the punching press mode.

After the arc-shaped section is stamped to form the reinforcing convex rib, the strength of the arc-shaped section can be improved, and the arc-shaped section is less prone to fracture compared with a traditional hoop under the same condition; and after the convex part is strengthened in the position punching press formation that the segmental arc meets with the straight plate section, can strengthen the intensity of this transition department, make it have stronger bearing capacity to resist the deformation fracture of staple bolt, above-mentioned protruding muscle of strengthening, strengthen the convex part fungible welding muscle, because strengthen protruding muscle, strengthen the convex part and all form through the punching press mode, processing is more simple and convenient, can improve production efficiency and reduce cost.

Furthermore, the inner side surface of the arc-shaped section is provided with knurls, so that the antiskid property of the hoop can be enhanced, and the phenomenon that the support and the assembly fall down due to the gliding of the hoop is avoided.

Furthermore, strengthen the protruding muscle and set up in the middle part of segmental arc, and strengthen the length of protruding muscle and be less than the length of segmental arc to the tip that makes to strengthen the protruding muscle has the predetermined distance with the straight board section of corresponding end between. Strengthen the intensity between the tip of protruding muscle and the straight board section of corresponding end and be less than the intensity at arc section middle part, utilize the bolt taut back with two staple bolt bodies like this, great deformation can be realized to this section to with the good laminating of tubular pile connected, guarantee to have good frictional force between staple bolt and the tubular pile.

Further, it has two to strengthen the convex part, the bolt hole is located two intermediate lines of strengthening the convex part to the intensity homoenergetic that guarantees the both sides position of bolt hole can effectively be strengthened, makes the both sides homoenergetic of segmental arc and the good laminating of the tubular pile of being connected.

The utility model discloses a photovoltaic support staple bolt simple structure, make convenient, with low costs, can adopt the raw and other materials of thin thickness to realize higher intensity to satisfy rigidity and the intensity demand of photovoltaic mounting structure system in mountain region and the extreme adverse circumstances photovoltaic power plant of the surface of water, have fine practicality.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.

Example 1:

this embodiment provides a photovoltaic support staple bolt rational in infrastructure to satisfy rigidity and the intensity demand of photovoltaic support structure system in mountain region and the extreme adverse circumstances photovoltaic power plant of surface of water.

The photovoltaic bracket hoop of the embodiment comprises two hoop bodies 1 which are connected through bolts 3 and are used for being connected with a tubular pile 2; as shown in fig. 1, the anchor ear body 1 is integrally formed by an arc-shaped section 11 at the middle part and straight plate sections 12 at two ends, and the straight plate sections 12 are provided with bolt holes 13 for the bolts to pass through; wherein, a reinforcing convex rib 14 protruding outwards is formed in the middle of the arc section 11 by stamping, the reinforcing convex rib 14 extends along the length direction of the arc section 11, and the length of the reinforcing convex rib 14 is smaller than that of the arc section 11, so that a preset distance is formed between the end part of the reinforcing convex rib 14 and the straight plate section 12 of the corresponding end; strengthen the intensity between the tip of protruding muscle 14 and the straight plate section 12 of corresponding end like this and be less than the intensity at the middle part of arc section 11, after utilizing bolt 3 tensioning two staple bolt bodies 1, great deformation can be realized to this section to with the good laminating of tubular pile 2 connected, guarantee to have good frictional force between staple bolt and the tubular pile 2.
