Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic building support technology, specifically a water guide component for a photovoltaic building integrated support system. Background Technology
[0002] The water guiding device of the building-integrated photovoltaic (BIPV) support system typically refers to the structural component used to guide and drain rainwater, seepage water, or cooling water, ensuring that the junction between the photovoltaic modules and the building facade does not accumulate water and prevents leakage, while also taking into account thermal management and aesthetics.
[0003] In existing technologies, after photovoltaic solar modules are installed on photovoltaic building brackets, if the external environment is rainy, a lot of water tends to accumulate on the surface after rain, which affects the service life.
[0004] To overcome the aforementioned shortcomings, a prior art Chinese patent (publication number CN223109963U) discloses a photovoltaic water guide plate fixing bracket and a vertical water guide component. The fixing bracket is used to fix the water guide plate, which includes an upward-opening water guide channel. The photovoltaic water guide plate fixing brackets are spaced apart along the length of the water guide plate, ensuring its stability. Furthermore, the structure of the water guide plate only needs to fulfill the drainage function of the water guide channel, which helps simplify the manufacturing process and reduce material and manufacturing costs. By setting water guide plate limiting parts on the left and right sides of the photovoltaic module connection portion, the limiting parts are connected to the two sides of the water guide channel, and the fixing bracket is fixed using the fixing connection part at the lower end of the limiting parts, thus completing the fixing of the water guide plate. Since the photovoltaic module connection portion is located inside the water guide channel, the connection and drainage functions of the photovoltaic module are satisfied.
[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, during drainage, the narrow gaps between the water tanks can easily affect the efficiency of water flow and drainage. Utility Model Content
[0006] The purpose of this invention is to provide a water guide for a building-integrated photovoltaic (BIPV) support structure, in order to solve the problem mentioned in the background art that affects the efficiency of drainage, increase the surface drainage of rainwater, and enhance the overall drainage capacity of the system.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a water guide for a building-integrated photovoltaic (BIPV) bracket, comprising a water guide body, a weather-resistant rubber pad, and a limiting rubber block, characterized in that: the water guide body is composed of an upper water guide plate, a rib plate, and a bottom clamping plate, wherein the upper water guide plate and the bottom clamping plate form a clamping structure, and the clamping structure is clamped on the frame of the upper row of solar cell modules, and rainwater on the surface of the upper row of solar cell modules flows along the upper surface of the upper water guide plate of the water guide body to the surface of the lower row of solar cell modules, reducing the amount of rainwater leaking from the gap between the upper and lower rows of modules.
[0008] Furthermore, the main body of the water guide is provided with ribs, and the ribs are in the middle part of the main body of the water guide, connecting the water guide plate and the bottom clamping plate. The upper water guide plate of the main body of the water guide is respectively the upper row of modules side and the lower row of modules side. The upper row of modules side is curved according to the upper edge of the solar cell module frame, which fits the module frame better and facilitates the drainage of rainwater on the surface of the upper row of solar cell modules. It is also more secure when clamped to the solar cell module frame. The lower row of modules side is designed to be flat and is only used to cover the lower row of modules frame and guide the surface rainwater to the surface of the lower row of solar cell modules.
[0009] Furthermore, a thin layer of weather-resistant rubber pad is provided on the inner side of the upper water guide plate assembly.
[0010] Furthermore, the bottom of the water guide rib is provided with a bottom clamping plate, and the angle between the lower end of the bottom clamping plate and the rib is less than 90 degrees, which makes the clamping of the solar cell module frame more secure.
[0011] Furthermore, a limiting rubber block is provided on one side of the lower row of components of the water guide rib. The limiting rubber block is glued on one side and is attached to the water guide rib to increase the spacing between the upper and lower rows of solar cell components and further increase the stability of the water guide after installation.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The water guiding component has a simple structure and can be extruded for easy mass production. It is also stable to install, improving stability. After installation, the water guiding device is not affected by thermal expansion and contraction, nor does it affect the thermal expansion and contraction space of the solar cell module.
[0014] 2. Using the aforementioned water guide can greatly increase the amount of water diverted from the upper row of solar cell modules to the surface of the lower row of solar cell modules, thereby reducing the amount of water falling through the gaps and reducing the pressure of water diversion in the water tank;
[0015] 3. Furthermore, the aforementioned water guide component solves problems such as material aging.
[0016] 4. Furthermore, the use of the aforementioned water guide can greatly improve installation accuracy and solve construction process problems such as positioning between upper and lower rows of solar cell modules. Attached Figure Description
