Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic systems, and specifically relates to a concrete roof photovoltaic bracket. Background Art

[0002] The installation of a photovoltaic power generation system on the roof of an existing building requires careful and comprehensive considerations. It is necessary to ensure the stability and safety of the building structure and not damage its original load-bearing and waterproof functions due to the installation of photovoltaic equipment. At the same time, the convenience and efficiency of the photovoltaic system installation must also be considered to ensure that the construction process does not cause too much interference with daily life and work.

[0003] Currently, when it comes to installing photovoltaic systems on concrete roofs of buildings, a common solution used in the industry is to combine steel structure photovoltaic brackets with concrete counterweights. This steel structure bracket system is usually composed of multiple key components, including columns, diagonal braces, diagonal beams, and purlins, which are connected by precisely designed bolts to ensure the stability and reliability of the entire bracket system. The photovoltaic bracket and the counterweight are connected and fixed by anchor bolts or pre-buried firmware to prevent displacement or tipping under the influence of natural factors such as wind.

[0004] However, this traditional installation scheme has exposed some problems in practical application. First, due to the large number of components and materials involved, the overall cost has increased and the management difficulty during the construction process has increased. Secondly, the installation process is relatively complicated and requires professional technicians and a long construction period, which to a certain extent limits its promotion in large-scale applications. Furthermore, since the installation accuracy is affected by many factors, such as worker skills, construction environment, etc., it is difficult to ensure that each photovoltaic bracket can achieve the best installation effect. Finally, this solution has poor flexibility. Once the design or installation is completed, it is difficult to adjust and modify it later.

[0005] In order to solve these problems, research and practice need to continuously explore new installation technologies and solutions to improve the installation efficiency of photovoltaic power generation systems, reduce costs, enhance safety, and improve their adaptability and flexibility. Therefore, it is urgent to provide a concrete roof photovoltaic bracket to solve the above problems. Utility Model Content

[0006] The utility model aims to overcome the problem of high efficiency and low cost of installing a photovoltaic system on a concrete roof of a building, and proposes a concrete roof photovoltaic bracket.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A concrete roof photovoltaic support, comprising columns, the top surface of the columns is set at an inclined angle, purlins are installed on the top surface of the columns, photovoltaic modules are installed on the purlins, several groups of columns are provided, and each group of columns includes a first column and a second column, and a height difference is provided between the first column and the second column.

[0009] Further, the inclined angle is the installation angle of the photovoltaic module.

[0010] Further, the columns are placed on the concrete roof.

[0011] Further, the columns are counterweight columns.

[0012] Further, the counterweight columns are of plain concrete or reinforced concrete structure.

[0013] Further, the inclined angle of the top surface of the first column is the same as the inclined angle of the top surface of the second column.

[0014] Further, the purlins are installed parallel to the top surface of the columns.

[0015] Further, the purlins include a first purlin and a second purlin, the first purlin is installed on the top surface of the first column of several groups of columns, and the second purlin is installed on the top surface of the second column of several groups of columns.

[0016] Further, the inclined angle of the purlin is the same as the inclined angle of the top surface of the column.

[0017] Further, the purlins are made of steel or aluminum.

[0018] Compared with the prior art, the utility model has the following beneficial technical effects:

[0019] A kind of concrete roof photovoltaic support provided by the utility model realizes the efficient installation of photovoltaic modules by setting an inclined angle on the top surface of the column and combining with the use of purlins. The top surface of the column forms an accurate inclined angle, and the setting of the inclined angle is based on the best light receiving angle of the photovoltaic module and the sunshine characteristics of the geographical location, ensuring that the photovoltaic module can receive solar radiation to the maximum extent. The purlin is installed on the top surface of the column. The purlin not only plays a role in supporting the photovoltaic module, but also ensures a reasonable spacing between the photovoltaic modules, which is beneficial to ventilation and heat dissipation and reduces shadow occlusion. The columns are designed into several groups, and each group includes a first column and a second column. A certain height difference is set between these two columns, which not only increases the sense of hierarchy and three-dimensionality of the photovoltaic module, but also helps to improve the power generation efficiency of the entire photovoltaic system. The utility model uses a small amount of materials, reduces costs, has a simple installation process, is easy to operate, reduces installation time and labor costs. Due to the adoption of precise design and installation techniques, the installation accuracy is high, ensuring the stability and reliability of the photovoltaic module, and has strong flexibility, which can be adaptively adjusted according to different terrain and climate conditions. It not only improves the efficiency and stability of photovoltaic power generation, but also reduces costs and time investment.

[0020] Furthermore, the counterweight column adopts a plain concrete or reinforced concrete structure. Both of these two materials have high strength and durability and can withstand various environmental factors for a long time. The counterweight column not only serves as a component to support the purlin, but also plays a role in weighing the photovoltaic support, ensuring the stability and safety of the entire structure.

[0021] Furthermore, the first purlin is installed on the top surface of the first column of several groups of columns, and the second purlin is installed on the top surface of the second column of several groups of columns to ensure the stability and safety of the photovoltaic module, which can provide sufficient support and fixation to prevent the photovoltaic module from shaking or tilting under the action of wind or other external forces.

[0022] Furthermore, the inclined angle of the purlin is the same as the inclined angle of the top surface of the column, which can ensure that the photovoltaic module remains stable during installation and can withstand a certain amount of wind and other external forces.

[0023] Furthermore, the installation angle of the photovoltaic module is the angle at which the top surface of the counterweight column is set as an inclined plane, which can ensure that the photovoltaic module receives sunlight at the best angle, thereby improving the power generation efficiency.

[0024] A kind of concrete roof photovoltaic support provided by the utility model has a simple structure and is easy to install, which can effectively improve the installation speed of the concrete roof photovoltaic support, reduce the investment of the photovoltaic support, and improve the project yield.
