Description

Technical Field

[0001] This utility model relates to the field of sound insulation wall panel technology, specifically a modular BIPV sound insulation wall panel for highways. Background Technology

[0002] BIPV (Build-Insulated Photovoltaic) sound barrier panels for highways are road infrastructure products that integrate photovoltaic power generation and sound insulation functions. BIPV sound barrier panels embed high-efficiency photovoltaic modules into the sound barrier, generating electricity through solar photovoltaic power, achieving both energy self-sufficiency and environmental protection. While their appearance is similar to traditional sound barrier panels, they offer significant functional advantages, providing efficient sound insulation while simultaneously powering road infrastructure, maximizing the utilization of solar energy resources.

[0003] Patent CN208369513U discloses a highway noise barrier structure with photovoltaic power generation function. A ground beam is fixedly installed on the side of the highway, with its bottom surface secured to the ground by anchor screws. The top of the ground beam has a mounting groove for fitting several standard frames. Photovoltaic power generation modules are fixedly installed on the top of each standard frame, and a noise barrier panel is fixedly installed on the bottom of each standard frame. Several standard frames are sequentially connected and embedded in the mounting groove to form the overall noise barrier structure. The joint between two adjacent standard frames is connected to the ground beam by an inclined tie rod. Insulated support rods extend outward from the bent parts of several standard frames, and transmission lines are installed on these rods. Several photovoltaic power generation modules are electrically connected to the transmission lines, which transmit the electrical energy generated by the photovoltaic power generation modules. This effectively combines the photovoltaic modules and the noise barrier into a single unit, generating electricity while providing sound insulation, thus improving efficiency and economic benefits.

[0004] The existing technology mentioned above combines photovoltaic modules and sound barriers into a single unit, generating electricity while providing sound insulation. Each standard frame is equipped with one photovoltaic module and one sound barrier, achieving modular assembly and facilitating installation. However, the standard frame is fixed to the ground beam by tilting rods and mounting grooves, and one tilting rod fixes two standard frames. When a standard frame is accidentally damaged, it is not easy to replace it individually, increasing the later maintenance costs. In view of this, we propose a modular highway BIPV sound barrier panel. Utility Model Content

[0005] The purpose of this invention is to provide modular BIPV sound insulation wall panels for highways to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A modular highway BIPV sound barrier panel includes a base for supporting the entire sound barrier panel structure. Multiple bent columns arranged equidistantly on the top of the base are detachably connected. A detachable bent frame is provided between two adjacent bent columns, connecting to the bent columns to form the main frame of the sound barrier panel. Soundproof panels and BIPV photovoltaic panels are installed on the bent frame. The BIPV photovoltaic panels are located above the soundproof panels. The soundproof panels effectively isolate and absorb highway noise, while the BIPV photovoltaic panels generate electricity by absorbing solar energy to power road infrastructure.

[0008] BIPV photovoltaic panels consist of multiple photovoltaic cells, which typically use semiconductor materials such as silicon. When sunlight shines on the surface of a photovoltaic cell, light particles are absorbed by the semiconductor material, thereby exciting electrons within the semiconductor material and generating electron-hole pairs. Electrons are negatively charged, and holes are positively charged. Their separation and movement form an electric current. The separated electrons and holes are then gathered at the two poles of the photovoltaic cell by an internal electric field. These poles are connected by wires to form a circuit. When an external load is connected to the circuit, the current in the photovoltaic cell flows, thus outputting electrical energy. This current is direct current (DC), which can be converted to alternating current (AC) by an inverter for power supply or feedback to the grid. BIPV photovoltaic panels are integrated into the structure of highway sound barrier panels, and the electricity they generate can be supplied locally to highway facilities such as streetlights, monitoring equipment, and traffic lights, or transmitted to the grid through transmission lines, achieving efficient utilization of electrical energy.

[0009] The rear side of the bent column is provided with multiple detachable connectors to connect the bent column and the bent frame. The connectors are designed to facilitate quick installation and disassembly, improving maintenance efficiency. One side of the bent frame is connected to the bent column through at least two connectors.

[0010] The connector includes a connecting plate, with an internally threaded tube on the front side near the outer end of the connecting plate. A circular alignment hole is provided on the rear side of the bending frame for the internally threaded tube to pass through. A threaded rod is internally threaded into the internally threaded tube. An annular pressure plate is provided on the outer wall of the threaded rod near the front end. A rubber pad is provided on the rear side of the annular pressure plate. The rear side of the rubber pad abuts against the front side of the bending frame to improve the stability after connection.

[0011] Preferably, the top of the base is provided with a strip-shaped positioning groove, and the bottom end of the bent column is inserted into the strip-shaped positioning groove to provide vertical support and facilitate the installation of the bent column.

[0012] Preferably, the base has multiple mounting holes a arranged equidistantly on the top and near the front, and multiple mounting holes a arranged equidistantly on the top and near the rear, for fixing to the ground with bolts to improve stability.

[0013] Preferably, mounting wing plates are provided on both the front and rear sides of the bent column and near the bottom. The top of the mounting wing plate is provided with a mounting hole b. A first bolt is connected in the mounting hole b. The first bolt is threaded to the top of the base to ensure the stability of the bent column.

[0014] Preferably, the bottom of both the front and rear sides of the bending frame is provided with strip-shaped base plates, the bottom of which fits against the top of the base to improve the fit with the base. Handles are provided on the front side of the bending frame near the left and right sides to facilitate the movement of the bending frame by the staff and to facilitate the installation and disassembly of the bending frame.

[0015] Preferably, the connecting plate has two mounting holes c on its rear side, and a second bolt is connected in the mounting holes c. The second bolt is threaded to the rear side of the bent column, which facilitates the disassembly and assembly of the connecting plate by the workers. This allows the workers to remove the unused connecting parts on the outermost bent column, thus avoiding the safety hazards caused by protruding connecting parts.

[0016] Preferably, the front end of the threaded rod is provided with a knob, and the outer wall of the knob is provided with anti-slip texture to facilitate the operator to rotate the threaded rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This modular BIPV sound insulation wall panel for highways features a modular design that allows the bending frame to be disassembled and replaced independently. When a module is damaged, only that single module needs to be replaced without affecting the overall structure, significantly reducing maintenance costs and improving maintenance efficiency.

[0019] 2. This modular highway BIPV sound barrier panel, with BIPV photovoltaic panels integrated into the sound barrier, not only achieves sound insulation but also effectively utilizes solar energy through photovoltaic power generation. This dual-function design improves the overall efficiency of the system, converting solar energy into electricity to power highway infrastructure such as streetlights, monitoring equipment, and traffic lights, or feeding the electricity back into the grid, achieving efficient energy utilization.

[0020] 3. This modular highway BIPV sound insulation wall panel is designed with multiple detachable connectors, including connecting plates, internally threaded pipes, threaded rods, annular pressure plates, and rubber pads, making the connection between the bent columns and the bent frame more stable and easier to operate. The threaded rod has a non-slip knob at the front end, which allows workers to quickly rotate and operate the system, improving the efficiency of system installation and disassembly, and reducing construction time and labor costs.

[0021] 4. This modular highway BIPV sound insulation wall panel features a rationally designed connector, avoiding potential safety hazards caused by protruding connectors. The connecting plate is securely connected to the bent column via mounting holes and a second bolt. The detachable design allows unused connectors to be removed, reducing the risks associated with redundant parts and improving safety. Attached Figure Description

When a bent column 2 is found to be damaged, the damaged bent column 2 can be pulled out of the strip positioning groove 10 by removing the first bolt 7 of the mounting wing plate 20, replacing it with a new bent column 2, and then tightening the mounting wing plate 20 to ensure stability. During maintenance, ensure that all operations are performed after the power is cut off to ensure the safety of the staff. Through the above steps, the installation and use of modular highway BIPV sound barrier panels can be realized. This system not only provides reliable sound insulation but also provides power to road facilities through the photovoltaic power generation system, achieving efficient and environmentally friendly energy utilization.
