Description

A roof fixture for a roof photovoltaic power generation system

technical field

The invention relates to a component of a photovoltaic power generation system, in particular to a roof fixing piece for a photovoltaic power generation system on the roof, which is used for the installation of solar cell components.

Background technique

At present, the continuous use of conventional energy has brought about a series of economic and social problems such as energy shortage and environmental degradation. The development of solar photovoltaic power generation technology is one of the ways to solve the above problems. Therefore, solar photovoltaic power generation technology has become a research hotspot worldwide. .

At the same time, in order to meet the needs of building energy conservation and environmental protection, a rooftop photovoltaic power generation system has emerged, which can effectively use the roof of the building, generate electricity in situ, and use it in situ, while reducing the temperature rise of the wall and roof, and reducing the air conditioning of the building. Load, has become one of the important technologies in the field of building energy conservation, and is also the most important form of solar photovoltaic applications. For example, Chinese invention patent application CN101105069A discloses a new type of solar photovoltaic roof system, which is composed of solar photovoltaic components, junction boxes, control systems, inverters, and aluminum alloy installation grooves; the aluminum alloy is fixed on the heat insulation layer on the building roof beams Mounting slots, install the horizontal sides of the solar photovoltaic components directly in the aluminum alloy installation slots on the roof beams of the building, connect the solar photovoltaic components in series and/or in parallel with the junction box and the control system, and then connect them to the inverter. Then output to the load power supply or the public grid, if the load is DC, it does not need to go through the inverter. The installation method of the solar photovoltaic roof system is: laying keels on the roof first, then connecting installation grooves to the roof keels, and finally laying solar photovoltaic components into the installation grooves.

However, the above solar photovoltaic roof system needs to calculate the position of the installation groove according to the size of the solar photovoltaic components during installation, and the solar photovoltaic components can only be laid in the installation groove after the installation of the installation groove is completed, so the installation is more troublesome.

Contents of the invention

The purpose of the present invention is to provide a roof fixing piece for a roof photovoltaic power generation system, so as to facilitate the installation of solar cell modules.

In order to achieve the above purpose, the technical solution adopted by the present invention is: a roof fixing part for a roof photovoltaic power generation system, including a connecting part, a supporting part arranged at the top of the connecting part, and a fixing part arranged at the bottom of the connecting part; Both sides of the supporting part are symmetrically provided with clamping grooves, and the middle part of the supporting part is provided with screw holes; the fixed part is provided with through holes; and the roof fixing part has an integrated structure.

In the above, the clamping groove of the support part should cooperate with the aluminum frame of the solar cell module, so as to clamp and fix the solar cell module in the clamping groove; The clamping grooves on the side, and for the roof fixing parts located in the middle of the components, the clamping grooves on both sides are used to clamp the two components on both sides respectively. The middle part of the support part is provided with a screw hole, and its function is to cooperate with the fasteners (such as existing aluminum angle pieces, gaskets, etc.) on the top of the module, and clamp and fix the module on the fasteners and the roof through bolts between the fixtures. The roof fixing part has an integrated structure, and can be made by drawing aluminum profiles, or by opening molds. The through holes of the fixing part are used in conjunction with self-tapping and self-drilling bolts to fix the entire roof fixing piece on the roof.

For the convenience of actual installation, the fixing part and the supporting part are arranged in a cross, preferably, there are two fixing parts, which are symmetrically arranged on both sides of the connecting part, and arranged in a cross with the supporting part.

In a further technical solution, the connecting portion is a hollow structure. The hollow structure is preferably a left-right symmetrical structure, which reduces the bearing capacity of the roof and saves material costs under the premise of ensuring strength.

In the above technical solution, the outer surface of the clamping groove of the support part is inclined inward, and the angle a between it and the horizontal plane is 30-90 degrees. This structure can better clamp and fix the solar battery module in the clamping groove, prevent the module from slipping out due to vibration and other reasons, and effectively avoid the shaking of the module.

The working principle of the present invention is: when installing the roof photovoltaic power generation system, the roof fixing parts and fasteners (such as existing aluminum angle pieces, gaskets, etc.) After the installation position, you can fix the roof fixing parts on both sides of the first solar cell module on the roof (that is, fix through the through holes of the fixing part of the roof fixing part), and then release the second solar cell to be installed. Fastener on one side of the module, and then insert the second solar cell module into the clamping groove of the roofing fixture (the bottom of the aluminum frame of the second component snaps into the clamping groove of the roofing fixture), and at the same time insert the second solar cell module into the clamping groove of the roofing fixture. Install the roof fixture on the other side of the battery module and fix it on the roof, tighten the fasteners on the first and second solar battery modules to complete the installation of the second module, and so on , to complete the installation of a column of modules; and so on for each column of modules to complete the installation of the rooftop photovoltaic power generation system.

Owing to above-mentioned technical scheme uses, the advantage that the present invention has compared with prior art is:

1. The roof fixture of the present invention can be laid directly on the roof without laying keels on the roof first, which greatly saves the materials and installation time of the roof photovoltaic power generation system, and reduces the cost.

2. During the installation process, the present invention can be pre-installed on the solar cell module in cooperation with fasteners (such as existing aluminum angle pieces, gaskets, etc.), and the second module can be inserted into the second module during the subsequent installation process. In the clamping groove of the roof fixing part on the side of a module, the modules can be installed directly one by one without calculating the position of each roof fixing part, which greatly saves installation time and is also easy to install, realizing rooftop photovoltaic power generation The neat and fast installation of the system.

3. The connection part of the present invention is made of a hollow structure, which reduces the bearing capacity of the roof and further saves material costs under the premise of ensuring strength.

4. The outer surface of the clamping groove of the support part of the present invention is inclined inwardly, so it can be installed on the solar cell module in advance in cooperation with the fastener, and can be transported together with the module, saving the transportation time and labor cost.
