Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a typhoon-resistant structure for a photovoltaic support based on a parapet wall. Background Technology

[0002] With the rapid development of the new energy industry, photovoltaic power generation, as an important form of clean energy utilization, is seeing its application scenarios continuously expand. Among them, rooftop photovoltaic systems are widely used due to their convenient installation and lack of additional land resources. However, in typhoon-prone areas, rooftop photovoltaic supports are subjected to huge horizontal wind loads from strong winds, which can easily lead to loosening of support connectors, bending of columns, or even complete overturning. This not only affects the normal use of the photovoltaic system but may also cause serious safety accidents.

[0003] Rooftops typically feature parapet walls, which are structurally sound, tightly connected to the building structure, and possess excellent load-bearing capacity. However, current technologies do not fully utilize the load-bearing capacity of parapet walls to enhance the typhoon resistance of photovoltaic (PV) mounting systems. Therefore, how to leverage the structural characteristics of roof parapet walls to improve the typhoon resistance of PV mounting systems is the technical problem this invention aims to solve. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a typhoon-resistant structure for photovoltaic brackets based on parapet walls. This structure combines the photovoltaic bracket with the parapet wall, making full use of the strength and stability of the parapet wall to effectively improve the typhoon resistance of the photovoltaic bracket.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a typhoon-resistant photovoltaic support structure based on a parapet wall, comprising a parapet wall, a main wind-resistant longitudinal beam, a first column support, a first column, a second column support, a second column, and a photovoltaic panel mounting frame; an anchor plate is embedded in the inner side of the parapet wall, and the main wind-resistant longitudinal beam is fixed to the anchor plate by anchors; the first column support and the second column support are spaced apart on their front and rear sides, and are respectively connected to the main wind-resistant longitudinal beam; the bottom of the first column is connected to the first column support, and the top is connected to the front side of the photovoltaic panel mounting frame; the bottom of the second column is connected to the second column support, and the top is connected to the rear side of the photovoltaic panel mounting frame.

[0006] As a further improvement of this utility model, the bottom of the first column is fixed on the first column support, and the top is hinged to the front side of the photovoltaic panel mounting frame; the bottom of the second column is hinged to the second column support, and the top is hinged to the rear side of the photovoltaic panel mounting frame; the second column is a telescopic structure, and the telescopic movement of the second column can drive the photovoltaic panel mounting frame to rotate along the hinge point at the top of the first column to adjust the tilt angle.

[0007] As a further improvement of this utility model, the photovoltaic panel mounting frame can switch between a low posture position and a high posture position by adjusting the tilt angle; when in the low posture position, the highest point of the photovoltaic panel mounting frame is lower than the top height of the parapet wall; when in the high posture position, the highest point of the photovoltaic panel mounting frame is higher than the top height of the parapet wall.

[0008] As a further improvement of this utility model, the second column adopts an electric telescopic rod, a pneumatic telescopic rod, a hydraulic telescopic rod, or a telescopic screw rod with a self-locking function.

[0009] As a further improvement of this utility model, the main wind-resistant longitudinal beam extends along the length of the parapet wall.

[0010] As a further improvement of this utility model, it also includes a concrete counterweight pier, wherein the first column support and the second column support are respectively set on independent concrete counterweight piers.

[0011] As a further improvement of this utility model, the outer wall of the parapet wall is set as an upward arc-shaped surface to guide the lateral wind to change its direction.

[0012] The beneficial effects of this utility model are as follows:

[0013] I. Enhancing the Typhoon Resistance of Photovoltaic Supports. By embedding steel plates in the anchors on the inner side of the parapet wall through the main wind-resistant longitudinal beams, the parapet wall and photovoltaic support are connected together. Horizontal wind loads are transferred to the parapet wall through the main wind-resistant longitudinal beams. By fully utilizing the stable structural characteristics of the parapet wall and its close connection with the main building structure, the typhoon resistance of the photovoltaic support is significantly improved, as well as its anti-overturning ability and connection stability.

[0014] Second, make full use of the existing structure to reduce costs. This structure innovatively uses the parapet wall as the main wind-resistant support, rather than using the main roof structure for reinforcement, thus avoiding excessive modification and reinforcement of the main roof structure, reducing reinforcement costs and the risk of roof damage.

[0015] Third, lightweight structure. The core load-bearing capacity of the photovoltaic support system relies on the parapet wall, so the photovoltaic support system and the main roof structure can be designed to be lighter, reducing the overall load.

[0016] Fourth, it has a wide range of applications. This structure is suitable for the roofs of industrial plants, commercial buildings, and residential buildings with sufficiently strong parapet walls, and has great potential for application in typhoon-prone coastal areas.

[0020] Marking description: Parapet wall 1, Anchor embedded steel plate 11, Main wind-resistant longitudinal beam 2, First column support 3, First column 4, Second column support 5, Second column 6, Photovoltaic panel mounting frame 7, Concrete counterweight pier 8. Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] like Figure 1-3 As shown, a typhoon-resistant photovoltaic support structure based on a parapet wall 1 includes a parapet wall 1, a main wind-resistant longitudinal beam 2, a first column support 3, a first column 4, a second column support 5, a second column 6, and a photovoltaic panel mounting frame 7.

[0023] Parapet wall 1 is set on the left and right sides of the main roof structure. Anchor steel plates 11 are installed on the inner side of parapet wall 1 along its length. The anchor steel plates 11 are welded and fixed to the steel reinforcement skeleton of parapet wall 1 to ensure a firm connection.

[0024] The main wind-resistant longitudinal beam 2 is made of steel and is fixed to the pre-embedded steel plate 11 of the anchor by anchors, and extends along the length of the parapet wall 1.

[0025] The first column support 3 and the second column support 5 are spaced apart on the front and rear sides. Both the first column support 3 and the second column support 5 are box-shaped structures welded from steel plates, and are connected to the main wind-resistant longitudinal beam 2 by bolts or welding. In addition, the first column support 3 and the second column support 5 are respectively set on independent concrete counterweight piers 8. The concrete counterweight piers 8 are set on the main roof structure, and the weight of a single concrete counterweight pier 8 is 500-800kg, which can provide stable support and anti-overturning force for the first column support 3 and the second column support 5.

[0026] The bottom of the first column 4 is welded to the first column support 3, and the top is hinged to the front of the photovoltaic panel mounting frame 7 via a hinge shaft. The bottom of the second column 6 is hinged to the second column support 5 via a hinge shaft, and the top is hinged to the rear of the photovoltaic panel mounting frame 7 via a hinge shaft. The second column 6 is a telescopic structure, employing an electric telescopic rod, pneumatic telescopic rod, hydraulic telescopic rod, or telescopic screw with a self-locking function. The extension and retraction of the second column 6 can drive the photovoltaic panel mounting frame 7 to rotate along the hinge point at the top of the first column 4 for tilt adjustment, and the self-locking function ensures that the photovoltaic panel mounting frame 7 remains stable after being adjusted to the required angle.

[0027] The photovoltaic panel mounting frame 7 is used to install photovoltaic panels and is constructed from spliced ​​profiles. It can switch between low and high tilt positions through tilt adjustment. In the low tilt position, the highest point of the photovoltaic panel mounting frame 7 is lower than the top of the parapet wall 1, allowing the parapet wall 1 to effectively block winds and reduce the impact of strong winds. In the high tilt position, the highest point of the photovoltaic panel mounting frame 7 is higher than the top of the parapet wall 1, reducing the shading of the photovoltaic panels by the parapet wall 1 and ensuring that the photovoltaic panels can fully receive sunlight.

[0028] The working principle of the above structure is as follows: During non-typhoon weather, the second column 6 is extended to adjust the photovoltaic panel mounting frame 7 to a high position, allowing the photovoltaic panels to fully receive sunlight and thus ensuring power generation efficiency. When a typhoon arrives, the second column 6 is shortened to adjust the photovoltaic panel mounting frame 7 to a low position. The parapet wall 1 acts as a windbreak to reduce the impact of strong winds on the photovoltaic panel mounting frame 7 and the photovoltaic panels. At the same time, the horizontal wind load is transmitted to the parapet wall 1 through the main wind-resistant longitudinal beam 2. With the strength and stability of the parapet wall 1, the typhoon resistance of the photovoltaic support is effectively improved. In addition, the lifting structure of the photovoltaic support is not only used for wind resistance, but also allows for adjustment of the tilt angle of the photovoltaic panels during non-typhoon weather, optimizing the power generation angle and facilitating equipment maintenance and cleaning.

[0029] In other embodiments, the outer wall of the parapet wall 1 can be configured as an upward-facing arcuate surface to guide the lateral wind upward and change its direction. When strong winds blow towards the parapet wall 1, the lateral airflow can form an upward vertical airflow along the arcuate surface, thereby forming a wind wall against the wind force on the upper part of the parapet wall, reducing the lateral wind speed, and preventing strong lateral winds from directly impacting the inside of the parapet wall, thus protecting the equipment inside the parapet wall.

[0030] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
