A novel building-integrated photovoltaic (BIPV) support system

Abstract

This utility model discloses a novel building-integrated photovoltaic (BIPV) support system, relating to the field of photovoltaic support systems. It includes a main water tank with a component bracket inside, the upper side of which is used to install solar cell components. A secondary water tank is installed at the connection seam between the solar cell components, perpendicular to the main water tank. This novel BIPV support system optimizes the cross-section of the main water tank, increasing its width and water-receiving width. This prevents rainwater flowing along the edge of the solar cell components from overflowing the main water tank area, significantly increasing the amount of rainwater it can hold and enhancing its waterproof performance, making it more suitable for larger roofs or roofs with high waterproof requirements. The secondary water tank installation method is also optimized. By installing rubber pads inside the secondary water tank, the bottom of the solar cell component frame can be pressed tightly against the edge of the main water tank via the rubber pads during installation. This fixes the secondary water tank, prevents slippage, reduces vibration noise, and lowers the risk of overflow.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically a novel building-integrated photovoltaic support. Background Technology

[0002] Building-integrated photovoltaic (BIPV) systems are support systems that integrate photovoltaic modules with the building structure. Their core functions are to provide reliable installation, positioning, and load transfer for photovoltaic modules, and to achieve roof waterproofing through various structures and measures, while minimizing the impact on building appearance, space utilization, and energy efficiency.

[0003] In existing technologies, structural connections often employ non-bolt, reliable and stable connection structures such as self-drilling screws, which pose certain waterproofing risks and can cause roof system leaks under certain circumstances.

[0004] To overcome the aforementioned shortcomings, a Chinese patent (publication number CN219033831U) discloses a building-integrated photovoltaic (BIPV) support structure, comprising: several middle pressure cover profiles, side pressure cover profiles, and a bottom frame profile; the bottom frame profile and the middle pressure cover profiles are connected to fix two adjacent photovoltaic modules between the bottom frame profile and the middle pressure cover profile to prevent rainwater from seeping downwards; the bottom frame profile and the side pressure cover profiles are connected to fix the side of the outermost photovoltaic module between the bottom frame profile and the side pressure cover profile for side waterproofing. This achieves active rain protection, preventing rainwater from seeping downwards and providing active waterproofing from the source.

[0005] Although existing technologies have taken the above issues into account, there are still shortcomings or hidden dangers in their operation due to inadequate measures or considerations. For example, the stability of the installation structure is insufficient, the stability of the connection is reduced due to personnel activities or long-term use, the waterproofing effect is poor, and the waterproofing performance of the building is affected. Utility Model Content

[0006] The purpose of this utility model is to provide a novel building-integrated photovoltaic (BIPV) support system to solve the structural stability and systemic waterproofing problems of the support system mentioned in the background art, and to provide a simple structure and convenient installation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel building-integrated photovoltaic (BIPV) support structure, comprising a main water tank, a secondary water tank, a water tank bracket, and a component bracket. The upper side of the main water tank is provided with a component bracket, and the upper side of the component bracket is used to install and fix solar cell components. The secondary water tank is installed at the gap between the solar cell components perpendicular to the main water tank, and the secondary water tank is placed between the solar cell components and the main water tank. The secondary water tank collects rainwater leaking from the joint between the solar cell components perpendicular to the main water tank. The main water tank collects rainwater leaking from the joint between the solar cell components along the direction of the main water tank and rainwater injected into the main water tank from the secondary water tank. The interiors of the main water tank and the secondary water tank constitute the main and branch channels for roof rainwater collection and transportation.

[0008] Furthermore, the main water tank is U-shaped, and the upper end of the main water tank has an outward-curved edge.

[0009] Furthermore, the main water tank installation mechanism is provided with a water tank bracket, and the water tank bracket is in the shape of an "L" shape. The water tank bracket is used to fix the main water tank to the building purlin by means of a first bolt.

[0010] Furthermore, the component bracket is made of steel stamped into a "W" shape, and the left and right ends of the component bracket are installed inside the main water tank by a bolt. The upper end of the component bracket is provided with the frame of the first solar cell component.

[0011] Furthermore, a rivet nut is embedded in the middle of the component bracket, and the solar cell module is installed onto the rivet nut of the component bracket by the second bolt through the component fixing block, thereby realizing the installation and fixing of the solar cell module.

[0012] Furthermore, the two ends of the secondary water tank are punched with downward bends to guide the rainwater collected in the secondary water tank into the main water tank. The interior of the secondary water tank is equipped with rubber pads, and the frame of the second solar cell module on which the solar cell module is installed presses the secondary water tank onto the flange of the main water tank through the rubber pads to fix the secondary water tank and prevent vibration and slippage.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The main water channel cross-section is optimized, greatly increasing the amount of rainwater it can hold, making it more suitable for larger roofs. By increasing the width of the main water channel, the water receiving width is increased, preventing rainwater flowing along the component frame from flowing out of the main water channel area.

[0015] 2. Optimize the combination of the main water tank and the auxiliary water tank. By setting a rubber pad between the solar cell module frame and the auxiliary water tank, the auxiliary water tank is pressed onto the flange of the main water tank, which can fix it and prevent the auxiliary water tank from vibrating and slipping. This can reduce the vibration noise of the auxiliary water tank and reduce the risk of overflow and leakage.

[0016] 3. Optimize the installation method. All structural connections are made with bolts to enhance structural strength and ensure the overall structural stability and safety. Attached Figure Description

[0025] The main water tank 2 is installed at the upper end of the building purlin via a water tank bracket 3 and a first bolt 4. The main water tank 2 has a concave cross-section with outward-facing small folded edges to increase structural strength and stability. Inside the main water tank 2, multiple component brackets 5 are also installed via the first bolt 4. Solar cell components 10 are installed at the upper end of the component brackets 5.
