Description

Double hook type flat-plate fastening system

Technical field

The utility model relates to a kind of double hook type flat-plate fastening system.

Background technique

Solar energy, as a kind of clean energy resource that can continuous utilization, has huge Application and Development potentiality.Along with warming of global climate is becoming tight with Energy situation, solar energy power generating, as one of a kind of continuable energy substitution mode, is developed by leaps and bounds.

Solar photovoltaic technology is the technology that converts solar energy into electric power, and its core is the semiconductor substance that can discharge electronics.The most frequently used semi-conducting material is silicon.Earth's crust silicon reserves are abundant, can be described as inexhaustible, nexhaustible.Solar-energy photo-voltaic cell has two-layer semiconductor, and one deck is anodal, and one deck is negative pole.Solar radiation is on semiconductor time, bipolar junction place generation current.

Photovoltaic generation is a kind of simple low-risk technology, almost can be arranged on any place that has illumination.This means that roof, metope and opening in both privately and publicly owned building has installs potentiality widely.

The most important feature of solar energy power generating is discharge CO seldom in power generation process ₂, and CO ₂as topmost greenhouse gases, be the arch-criminal who causes climatic change.

The energy and environmental problem are recent the focus of world attention, and in order to realize the sustainable development of the energy and environment, countries in the world are the emphasis using photovoltaic generation as development all.In the long term, solar energy power generating can occupy the important seat of world energy sources consumption in the near future.

Solar energy power generating installation system is one or more solar photovoltaic assembly to be placed on the mounting bracket with some strength and the installation system that forms.Manufacturer and the supplier of overwhelming majority solar components do not produce installation system.

In order to meet the installation of solar components or other flat board, German patent DE 19717996A1 has described the connecting means of solar collector and roof bracket.It is that roof is installed and linked up with on the batten that is fixed on roof placement tile, the other end of hook is installed and is clamped for placing the pipe of solar collector.With another support, solar collector and pipe are fixed.In this installation method, the narrow space between roof sheet tile and solar collector, installs inconvenience.

In US Patent No. 6105317, only set forth the top installation system of solar photovoltaic assembly, require when mounted two distances between guide rail to be not only a certain width of solar photovoltaic assembly, and two guide rails just drop on again on the immovable point of material installed surface, carry out fastening, this just need to be in advance through accurate Calculation and make the surperficial immovable point of material installed.

US Patent No. 6360491B1 has described the solar components installation method of slider nut.It is to make bolt pass aperture, mounting guide rail and pillar is fastening that the method need to be carried out drilling operation in mounting guide rail bottom in erecting bed, and this installation method has increased difficulty and the intensity of installing, and can only carry out the top installation of solar components.

German patent DE 10132557A1 provides the installation system of solar photovoltaic assembly on roof, and it is fastened on photovoltaic module between pressing plate and basal orbit by screw.Basal orbit is fitted tightly both toothed surfaces tighten together by screw with the support that is arranged on roof.Because the fastening means of this system is that screw rotates into open groove on the basal orbit that relatively softwood matter is made and forms fasteningly, this fastening means is affected the tensile strength of this system.

Although can carrying out solar components or other dull and stereotyped top and the back side, the solar components that US Patent No. 7260918B2 provides or other dull and stereotyped installation system install, because being needs to rely on guide rail rigidity intensity to meet system tensile strength completely, this just need to increase the wall thickness of guide rail.Cause mounting material to increase.

US Patent No. 2006/0086382A1 provides and solar components has been placed between upper and lower two guide rails and with fastening piece and through get on the right track top and lower railway bottom, solar components or other flat board is tightened together with upper and lower track, the installation method that lower railway is fastenedly connected by fastening piece and supporting track again.Whole installation system need to be used three guide rails, and mounting material consumption increases greatly, and installation cost also can increase, and installation workload increases simultaneously.

US Patent No. 2006/0156651A1 has shown the installation system of meshing blocks structure.This system needs mounting guide rail and connection guide rail to form system guide rail, and installation procedure increases, and mounting material also has greatly increased.

US Patent No. 2008/0310913A1 has set forth to clamp to be had the guide rail of a cavity body and makes it to be fixed on an other guide rail or other objects.The guide rail structure that this method is used is relatively complicated, and materials'use can be relatively many.

US Patent No. 2010/0269447A1 has shown a kind of by the gap between two protrusions on two symmetrical flanges of guide rail embedding, and the elasticity that relies on two flanges to have is clamped guide rail.Rely on flange elasticity to clamp guide rail and be easy to cause that guide rail direction guiding rail bearing of trend moves, this just must use additive method to prevent that guide rail is to the movement of its bearing of trend.This can increase the cost of installation.

In existing solar components or other dull and stereotyped installation system, seldom have and use two hook modes can either on a mounting guide rail, complete solar components or other fastening installation in dull and stereotyped top as link, also can complete the fastening installation in solar components bottom, and be fastenedly connected with material installed surface together with solar components or other dull and stereotyped and mounting guide rail.And can use a guide rail to complete in the minority product of above-mentioned work, owing to need to improving the tensile strength of installation system, use the heavy duty guide rail that metal consumption is very large.So just increased the raw material consumption of installation system.
