Description

Module installation clamps and photovoltaic brackets

Technical field

The present disclosure relates to a module mounting pressing block for pressing two adjacent photovoltaic modules on a bracket purlin, and also relates to a photovoltaic bracket.

Background technique

Photovoltaic power generation is a form of new energy that is being vigorously developed around the world. It is also the power generation method with the largest installed capacity and growth among new energy sources. In photovoltaic power generation applications, photovoltaic modules are devices that use the photovoltaic effect to convert light energy into electrical energy. In photovoltaic power stations, photovoltaic brackets are used to support photovoltaic modules to ensure that the photovoltaic modules form a fixed tilt angle and are not damaged by bad weather.

One connection method between photovoltaic modules and photovoltaic brackets is press block installation. Pressure block installation is to use module installation pressure blocks to press the photovoltaic modules on the bracket purlins. This method protects the component borders from being damaged.

However, when installing the press blocks, an installer needs to work on top of the photovoltaic module, and other installers need to tighten it below. The installation is very inconvenient and even requires high-altitude operations, which is dangerous. At the same time, there is a risk of accidentally damaging the photovoltaic modules when working on top of them.

Therefore, there is a need to provide solutions that can simplify the installation of such photovoltaic modules.

Detailed ways

The present disclosure will be further described below in conjunction with the specific embodiments and drawings. More details are set forth in the following description to fully understand the present disclosure. However, the present disclosure can obviously be implemented in a variety of other ways that are different from this description. Those skilled in the art can make similar generalizations and deductions based on actual application conditions without violating the connotation of the present disclosure. Therefore, the protection scope of the present disclosure should not be limited by the content of this specific implementation.

For example, a first feature described later in the specification is formed above or on a second feature, which may include an embodiment in which the first feature and the second feature are directly connected, or may include an embodiment in which the first feature and the second feature are formed. Embodiments of additional features are formed between them, so that there may not be a direct connection between the first feature and the second feature. Further, when a first element is described as being connected or combined with a second element, this description includes embodiments in which the first element and the second element are directly connected or combined with each other, as well as embodiments in which one or more other intervening elements are used. Addition causes the first element and the second element to be indirectly connected or coupled to each other.

Usually the connection form between photovoltaic modules and photovoltaic brackets is bolt installation or pressure block installation.

Bolt installation uses four to eight bolts to directly connect the mounting holes on the photovoltaic module frame and the module mounting holes of the bracket. However, this method is a single-point connection between the photovoltaic module and the bracket. When the photovoltaic module frame is thin, when it is affected by strong wind, only the bolt part of the frame is partially stressed, and the frame is easy to tear, causing the module and the bracket to loosen, and the photovoltaic module becomes loose or fall.

Pressure block installation usually uses module installation pressure blocks to press and install photovoltaic modules on the bracket purlins, such as the ∏-type or Ω-type pressure blocks mentioned later. Compared with bolt installation, the use of pressure block installation can protect photovoltaic modules, especially Component borders are not destroyed.

However, as the size of photovoltaic modules becomes larger and larger, the frame length of photovoltaic modules usually exceeds 2 meters. During the installation process, the mounting bolts of the module mounting clamp need to penetrate from the top of the module mounting clamp and pass through the bracket purlin. Install nuts and tighten. During the tightening process, the mounting bolts need to be fixed above the photovoltaic modules with tools such as wrenches or sleeves, and tightened below the photovoltaic modules. At this time, the installer needs to work above the photovoltaic module surface, and another person needs to tighten it below, which makes the installation very inconvenient. Especially when the height of photovoltaic modules is high, high-altitude operations are required, which is dangerous. Moreover, when construction work is carried out above photovoltaic modules, there is a risk of accidentally damaging the photovoltaic modules.

Therefore, the inventor started from improving the component mounting clamp itself and provided a new type of component mounting clamp. When this component is used to install the press block, no one is required to operate above the photovoltaic module surface during installation, so that a single person can operate below the photovoltaic module.

1 and 2 illustrate a first embodiment of the present disclosure. Among them, FIG. 1 shows the three-dimensional structure of the component mounting pressure block 10 , and FIG. 2 shows the installation structure of the component mounting pressure block 10 .

1 and 2 , the module mounting pressing block 10 is used to press two adjacent photovoltaic modules 20 onto the bracket purlin 30 . The component mounting pressure block 10 includes a hole portion 11 . The hole portion 11 is provided with through holes 4 through which the mounting bolts 5 pass.

The component mounting pressure block 10 also has a stop surface 3 . The stop surface 3 protrudes upward from the hole portion 1 , and the stop surface 3 restricts the rotation of the mounting bolt 5 by pressing against the bolt head 51 of the mounting bolt 5 .

It can be understood that the use of spatial relationship words such as "upper", "lower", etc. to describe the relationship between one element or feature and other elements or features shown in the drawings is with reference to the usual placement state of the photovoltaic bracket. , to facilitate description. If the photovoltaic support is turned upside down, the above spatial relationship terms should be interpreted accordingly.

It can also be understood that "along" a certain direction or "in a certain direction" means that there is at least a component in that direction. Preferably, the included angle with the direction is within 45°, and more preferably, the included angle is within 20°. Even within 5°. The two directions "perpendicular", "consistent", and "parallel" mentioned in the article do not need to meet strict angle requirements in the mathematical sense, but allow a certain tolerance range. For example, compared to the mathematical requirements The angle difference is within 20°.

The above-mentioned component mounting pressure block 10 restricts the rotation of the mounting bolt 5 by setting a stop surface 3 next to the through hole 4, Therefore, when installing the component mounting clamp 10, you only need to insert the mounting bolt 5 from above the component mounting clamp 10, so that the bolt head 51 can abut the stop surface 3, and put the component mounting clamp 10 into the adjacent Between the two photovoltaic modules 20, the mounting bolts 5 pass through the bracket purlin 30 and are tightened with nuts. Since the bolt head 51 of the mounting bolt 5 has been stopped by the stop surface 3 and cannot rotate, only one operator is required to tighten the nut below.

The polygonal cylinder can be a rectangle or a regular hexagon as shown in the figure. The mounting bolts 5 can be hexagonal heads, rectangular bolt heads or other special-shaped bolt heads.

As shown in FIG. 1 , the outer ring wall surface 612 of the convex ring 61 may be a cylindrical surface. It can be understood that a cylinder is a curved surface formed by a moving straight line moving parallel to a fixed curve. For example, the polygonal cylinder surface, that is, the definite curve, is a polygonal contour line, and the cylindrical surface, that is, the definite curve, is a circular line.

As shown in FIG. 2 , the module mounting pressing block 10 may have two pressing surfaces 13 that directly contact the two photovoltaic modules 20 respectively. Each pressing surface 13 may be provided with a serrated protrusion 131 . For example, the pressing surface 13 may be the lower surface of the two side parts 12 .
