Description

Double hook type flat fastening system

The present invention relates to a double hook type flat panel fastening system. Background technique

As a sustainable energy source that can be continuously used, solar energy has great potential for development and application. As the global climate changes and the energy situation tightens, solar photovoltaic power generation, as one of the sustainable energy alternatives, has developed rapidly.

Solar photovoltaic technology is a technology that converts solar energy into electricity, and its core is a semiconductor material that can release electrons. The most commonly used semiconductor material is silicon. The crustal silicon is rich in reserves and can be said to be inexhaustible. A solar photovoltaic cell has two layers of semiconductor, one on the positive side and one on the negative side. When sunlight hits the semiconductor, current is generated at the junction of the two poles.

Photovoltaic power generation is a simple, low-risk technology that can be installed in almost any light. This means extensive installation potential on the roofs, walls and open areas of public and private buildings.

The most important feature of solar photovoltaic power generation is the emission of little co ₂ during power generation, and co ₂ as the main greenhouse gas is the chief culprit in climate change.

Energy and environmental issues are the focus of recent world attention. In order to achieve sustainable energy and environmental development, photovoltaic power generation is the focus of development in the world. In the long run, solar photovoltaic power generation will occupy an important seat in world energy consumption in the near future.

A solar photovoltaic power installation system is a mounting system formed by placing one or more solar photovoltaic modules on a mounting bracket having a certain strength. Most manufacturers and suppliers of solar modules do not manufacture mounting systems.

In order to meet the installation of solar modules or other flat panels, German Patent DE 197 17 996 A1 describes a method of joining solar collectors to roof supports. It is to attach the roof mounting hook to the wooden strip on which the roof is placed, and the other end of the mounting hook clamps the round tube for the solar collector. Secure the solar collector to the round tube with another bracket. In this installation method, the space between the roof tile and the solar collector is small and the installation is inconvenient.

In US Pat. No. 6,105,317, only the top mounting system of the solar photovoltaic module is described. The installation requires that the distance between the two rails is not only a certain width of the solar photovoltaic module, but also two guides. The rails must be placed just on the surface of the object to be fastened, which requires accurate calculation and fabrication of the surface of the object to be mounted.

U.S. Patent No. 6,364,091 B1 describes a solar module mounting method for a slider nut. This method requires drilling at the bottom of the mounting rail at the installation site to allow the bolts to pass through the holes to secure the mounting rails to the struts. This method of installation increases the difficulty and strength of the installation and allows only the top mounting of the solar modules. .

German patent DE 10 132 557 A1 provides a roofing system for solar photovoltaic modules which screws the photovoltaic modules between the pressure plate and the base rail. The base rail and the bracket mounted on the roof are screwed together to secure the two toothed surfaces together. Since the fastening method of the system is such that the screw is rotated into an open groove formed on a base rail made of a relatively soft material, the fastening method affects the tensile strength of the system.

The solar module or other flat panel mounting system provided by U.S. Patent No. 7,260,918 B2, although it is possible to mount solar modules or other flat top and back panels, requires full increase in the wall thickness of the rails due to the need to rely on the rigid strength of the rails to meet the tensile strength of the system. Causes an increase in installation materials.

US 2006/0086382 A1 provides for placing a solar module between the upper and lower rails and fastening the solar module or other panel to the upper and lower rails with fasteners through the top of the upper rail and the bottom of the lower rail. A mounting method in which the fastener is fastened to the support rail. The entire mounting system requires three rails, the amount of mounting material is greatly increased, the installation cost is also increased, and the installation workload is increased.

U.S. Patent No. 2006/0156651 A1 shows a mounting system for engaging a slider structure. The system requires the installation of guide rails and connecting rails to form system rails, the installation process is increased, and the installation materials are also greatly increased.

U.S. Patent No. 2008/0310913 A1 describes the clamping of a rail having a hollow body and securing it to another rail or other object. The rail structure used in this method is relatively complicated and the material is used relatively more.

U.S. Patent No. 2010/0269447 A1 shows a gap in which the rails are embedded between two projections on two symmetrical flanges and the rails are clamped by the elasticity of the two flanges. Relying on the flange to elastically clamp the rail easily causes the rail to move in the direction in which the rail extends. This requires other methods to prevent the rail from moving in the direction in which it extends. This will increase the cost of the installation.

In existing solar modules or other flat panel mounting systems, it is rare to use a double hook as a connector to complete the solar module or other flat top fastening on a mounting rail. It is also possible to complete the fastening installation of the bottom of the solar module and to fasten the surface of the object to be mounted together with the solar module or other flat plate and mounting rail. In a few products that can use a rail to do the above work, heavy-duty rails with a large amount of metal are used due to the need to increase the tensile strength of the mounting system. This increases the amount of raw materials used in the installation system. Summary of the invention
