Description

Technical Field

[0001] This utility model relates to the field of photovoltaic sound barrier technology, specifically to a photovoltaic sound barrier that combines sound insulation and photovoltaic power generation functions, and is easy to install and maintain. Background Technology

[0002] With the rapid development of transportation, noise pollution from highways, railways, and other transportation lines has seriously affected the living environment of surrounding residents. Sound barriers, as an effective facility for controlling traffic noise, are widely used. Meanwhile, against the backdrop of an increasingly severe global energy crisis, solar energy, as a clean and renewable energy source, has received high attention for its development and utilization.

[0003] Currently, some photovoltaic sound barriers have appeared on the market, combining photovoltaic power generation with sound insulation functions to achieve comprehensive resource utilization. However, existing photovoltaic sound barriers still have some shortcomings in structural design. The frame structure of some photovoltaic sound barriers lacks effective heat dissipation and drainage design. During long-term use, rainwater easily accumulates inside the frame, leading to corrosion and damage to components. At the same time, poor ventilation will cause the operating temperature of the photovoltaic panels to rise, affecting power generation efficiency. In addition, the installation and maintenance process of existing photovoltaic sound barriers is relatively cumbersome. The connection between the frame and the internal sound insulation panels and photovoltaic panels is complex. When it is necessary to replace or repair components, it is time-consuming and labor-intensive, increasing operation and maintenance costs.

[0004] Therefore, developing a photovoltaic sound barrier that has good heat dissipation and drainage performance, is easy to install and maintain, and can effectively improve sound insulation and photovoltaic power generation efficiency is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency photovoltaic sound barrier with heat dissipation function.

[0016] The tail end of the second pressing inclined plate is connected to the head end of the third pressing plate;

[0017] The third pressing plate abuts against the sound insulation board.

[0018] The Z-shaped structure adapts to the installation gap, eliminating the need for frame adjustment and ensuring a snug fit to the sound insulation panel to prevent loosening; the bolted connection and flat plate abutment provide uniform tightening force, preventing vibration and displacement of the sound insulation panel; it can be disassembled and installed simply by tightening bolts, without dismantling the frame, saving time for maintenance and replacement; the standardized components are easy to process, adapting to different specifications of sound barriers, and are cost-effective.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] The ventilation holes at the top and bottom of the frame serve both ventilation and drainage functions. The ventilation function can reduce the operating temperature of the photovoltaic panels and improve power generation efficiency, while the drainage function can promptly remove rainwater, preventing water accumulation inside the frame from causing component corrosion and extending the service life of the sound barrier.

[0030] The clamping components on the frame enable quick assembly and disassembly, simplifying the installation and maintenance process, reducing operation and maintenance costs, and allowing for rapid replacement of damaged components, thus improving maintenance efficiency.

[0045] Preferably, the flow holes 4 at the upper and lower ends of the frame 1 are arranged one-to-one, and the inner side of the flow holes 4 is equipped with a filter screen 12, which has both ventilation and drainage functions.

The number and size of the flow holes 4 are determined according to the size of the photovoltaic sound barrier frame 1 and actual needs, and the uniformity of ventilation and drainage must be ensured.

[0046] Preferably, the back of the photovoltaic panel 2 has a plurality of equally spaced vertical fins 7.

[0047] Preferably, the sound insulation plate 3 has vertical grooves 8 that are equally spaced and match the fins 7 on the side near the photovoltaic panel 2.

[0048] Preferably, the fin 7 can be snapped into the groove 8.

[0050] Preferably, the pressure block 9 can be pressed onto the sound insulation plate 3 by fastening the bolt 10 and the threaded hole 5.

[0051] This utility model includes a photovoltaic panel 2, a sound insulation panel 3, and an installation frame 1 for fixing the photovoltaic panel 2 and the sound insulation panel 3. The frame 1 has flow holes 4 at its top and bottom. Pressing components 6 for fixing the sound insulation panel 3 are evenly arranged on the left and right sides of the frame 1. The pressing components 6 press the grooves 8 of the sound insulation panel 3 onto the fins 7 that are fixedly connected to the photovoltaic panel 2, and then fix the photovoltaic panel 2 to the photovoltaic panel assembly side opening 13 through the fins 7. The back of the photovoltaic panel 2 has vertical fins 7, and the sound insulation panel 3 has vertical grooves 8 on the side opposite to the photovoltaic panel 2, which can accommodate the fins 7.

[0052] To better illustrate the technical effects of this utility model, the present utility model provides the following specific embodiments to explain the above technical process:

[0053] Example 1: A photovoltaic sound barrier that not only achieves effective sound insulation and photovoltaic power generation, but also has good heat dissipation and drainage performance, and is easy to install and maintain, effectively extending its service life and reducing operation and maintenance costs.

[0054] Specifically, it includes:

[0055] Frame 1, photovoltaic panel 2, and sound insulation board 3;

[0056] The interior of frame 1 is used for fixing and installing sound insulation board 3 and photovoltaic panel 2;

[0057] The frame 1 has flow holes 4 at both the top and bottom. The number of flow holes 4 is determined according to the size of the photovoltaic sound barrier frame 1, and the flow holes 4 at the top and bottom are set one-to-one to ensure the uniformity of ventilation and drainage.

[0058] The inner side of the flow hole 4 is equipped with a filter screen 12, which has ventilation and drainage functions. On the one hand, it can realize the air circulation inside the sound barrier, reduce the temperature of the photovoltaic panel 2 when it is working, and improve the power generation efficiency. On the other hand, it can drain the rainwater in the frame 1 in time through the drainage channel at the top of the crash barrier, and avoid the rainwater accumulation leading to component corrosion.

[0059] A clamping assembly 6 is provided around the frame 1. The clamping assembly 6 includes a clamping block 9 and a fastening bolt 10. The frame 1 has threaded holes 5 that match the fastening bolt 10. The clamping block 9 is clamped onto the sound insulation plate 3 inside the frame 1 by the fastening bolt 10, so as to quickly fix the sound insulation plate 3 and the photovoltaic panel 2. When disassembly is required, simply loosen the fastening bolt 10 to remove the clamping block 9 (the size of the sound insulation plate 3 and the photovoltaic panel 2 are slightly smaller than the size of the opening 11 on the side of the sound barrier). The sound insulation plate 3 or the photovoltaic panel 2 can then be taken out from the frame 1. The operation is convenient and greatly simplifies the installation and maintenance process.

[0060] The photovoltaic panel 2 has vertically spaced fins 7 on its back side. The sound insulation plate 3 has grooves 8 that match the fins 7. The fins 7 are snapped into the grooves 8 of the sound insulation plate 3. This connection method not only makes the photovoltaic panel 2 and the sound insulation plate 3 more firmly fixed, but also the fins 7 can further enhance the ventilation effect inside the sound barrier, accelerate air circulation, and reduce the temperature of the photovoltaic panel 2. Furthermore, the cooperation between the fins 7 and the sound insulation plate 3 can enhance the overall sound insulation performance of the sound barrier and effectively block the transmission of noise.

[0061] Preferably, the flow hole 4 can be designed as a square hole, a circle, etc.

[0062] Preferably, the spacing between the fins 7 is 2 to 4 cm, and the height of the fins 7 from the back panel of the photovoltaic panel 2 is 1.5 to 2.5 cm.

[0063] Preferably, the groove 8 of the sound insulation board 3 has a depth of 1-5mm, which can accommodate the fins 7. The small space formed by the fins 7, the photovoltaic panel 2, and the sound insulation board 3 can further improve the overall sound insulation performance and effectively block noise transmission.

[0064] Preferably, the fins 7 are made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant. It can enhance ventilation and sound insulation without increasing the overall weight of the photovoltaic panel 2.

[0065] Preferably, when there is a need for landscaping, the sound insulation board 3, the fins 7, and the photovoltaic panel 2 can all be made of transparent materials. For example, the sound insulation board 3 can be made of transparent acrylic sheet, and the photovoltaic panel 2 can be made of cadmium telluride power generation glass, etc.

[0066] Preferably, the pore size of the filter screen is selected according to local climate, vegetation and other conditions to prevent leaves, flies and other insects from entering the photovoltaic sound barrier, while ensuring good ventilation and drainage.
