Description

Technical Field

[0001] The utility model relates to the field of photovoltaic engineering, and specifically refers to a photovoltaic wind-resistant auxiliary structure. Background Art

[0002] Photovoltaic technology refers to a technology that uses semiconductor materials, especially silicon-based materials, to generate electricity under sunlight. The core of this technology is solar cells, which can directly convert the sun's light energy into electrical energy. It is a clean and renewable form of energy. Photovoltaic systems usually consist of solar panels (also called photovoltaic panels), supporting structures, cables and inverters. Solar panels are usually installed on the roof of a building or on open ground to maximize the amount of sunlight received. And it is precisely because of this that when encountering strong winds, photovoltaic panels cannot withstand strong winds and are easily blown away and fall, causing danger and loss. Therefore, when installing photovoltaic panels, corresponding wind-resistant measures must be taken.

[0003] In traditional technology, photovoltaic panels only use metal brackets, which are fixed on the metal brackets by screws, and the metal brackets are fixed on the concrete base to achieve the purpose of wind resistance. However, the defects of this wind resistance are:

[0004] On the one hand, most existing metal brackets are hollow, so the connection between them and the photovoltaic panels mostly relies on the threads of rivets for fixation, and the force they bear is relatively single. When strong winds blow, the wind load of the photovoltaic panels will be directly transmitted to the screws or rivets. Because the force bearing point is single, the photovoltaic panels are easily torn or bent, causing damage;

[0005] On the other hand, photovoltaic panels need to face the sun, so they are often placed diagonally. Then, when the bottom of the panel facing away from the sun is blown by strong winds, the wind force is concentrated on the bottom of the panel, which can easily lift up the entire photovoltaic panel together with the bracket, eventually causing damage.

[0006] In view of this, it is necessary to improve the above defects. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the above-mentioned defects and provide a photovoltaic wind-resistant auxiliary structure.

[0008] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0009] A photovoltaic wind-resistant auxiliary structure comprises a photovoltaic panel body arranged obliquely, a frame is arranged above the photovoltaic panel body, a flange is arranged at the outer bottom end of the frame, a plurality of evenly distributed screw holes are opened at the front and rear ends of the flange, a receiving plate is arranged below the photovoltaic panel body, both sides of the top end of the receiving plate are fixedly connected with slide rails, the two side parts of the flange are slidably connected to the slide rails, a plurality of evenly distributed screw holes are opened at the front and rear ends of the receiving plate, an upper arc portion is arranged at the bottom end of the receiving plate, a lower arc portion is arranged below the upper arc portion, a base is fixedly connected to the bottom end of the lower arc portion, the base and the upper arc portion are connected to each other by supporting feet, the front and rear ends of the flange are slidably connected with fixing strips, and a plurality of evenly distributed screw holes are opened on the fixing strips.

[0010] As an improvement, the frame fits tightly with the photovoltaic panel body and the receiving plate.

[0011] As an improvement, the arc surface of the upper arc portion faces downward, and the arc surface of the lower arc portion faces upward.

[0012] As an improvement, the screw hole one, the screw hole two and the screw hole three are fastened and connected by screws.

[0013] As an improvement, the upper arc portion and the receiving plate are formed integrally.

[0014] As an improvement, the support leg is connected to the upper arc portion by welding, and the support leg is connected to the lower arc portion by rivets.

[0015] Compared with traditional technologies, the advantages of the present invention are: 1. The present invention adopts a frame and a combined fixing strip to be fixed to a receiving plate, so that when the photovoltaic panel body is subjected to wind load, the force can be dispersed by the flanges of the frame and the fixing strip, so that the photovoltaic panel is evenly stressed and is not easily torn or bent.

[0016] 2. The utility model has an upper arc portion at the bottom end of the receiving plate and a lower arc portion at the top end of the base. When the wind blows to the back of the photovoltaic panel, the wind will be guided by the surfaces of the upper arc portion and the lower arc portion and flow faster, which creates a pressure difference between the top and bottom surfaces of the photovoltaic panel. Under the action of atmospheric pressure, the entire device can be pressed against the bottom surface, thereby improving its wind resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 to Figure 4As shown, the utility model proposes a photovoltaic wind-resistant auxiliary structure, which includes a photovoltaic panel body 1 arranged obliquely, a frame 2 is arranged above the photovoltaic panel body 1, the body of the frame 2 is opened, and the frame part of the photovoltaic panel body 1 is buckled from the top, and at the same time, a flange 3 is arranged at the bottom end of the outer side of the frame 2, and a plurality of evenly distributed screw holes 4 are opened at the front and rear ends of the flange 3, and a receiving plate 5 is arranged below the photovoltaic panel body 1, and the top two sides of the receiving plate 5 are fixedly connected with slide rails 6, and the two side parts of the flange 3 are slidably connected to the slide rails 6, and the frame 2 is tightly fitted with the photovoltaic panel body 1 and the receiving plate 5 to form a preliminary fixation, and then, the front and rear ends of the receiving plate 5 are opened with a plurality of evenly distributed screw holes 4. The evenly distributed screw holes 7, the front and rear ends of the flange 3 are slidably connected with a fixing strip 12, and the fixing strip 12 is provided with a number of evenly distributed screw holes 3 13. When in use, the screw holes 1 7, the screw holes 2 4, and the screw holes 3 13 overlap at corresponding positions and are fastened and connected by screws 14. In this way, an overall structure is formed with the receiving plate 5 at the bottom, the photovoltaic panel body 1 in the middle, and the frame 2 at the top. Because they fit tightly together, when the equipment encounters strong winds, the wind blows onto the panel surface or the panel body of the photovoltaic panel body 1, and the impact force brought thereto will be dispersed by the fixing strip 12 and the frame 2, so that the force is evenly distributed, avoiding the risk of the impact force being concentrated at one point and being blown away.

[0025] Subsequently, in the utility model, an upper arc portion 8 is further provided at the bottom end of the receiving plate 5, and a lower arc portion 9 is provided below the upper arc portion 8, the arc surface of the upper arc portion 8 faces downward, and the arc surface of the lower arc portion 9 faces upward. Therefore, when wind blows through the bottom surface of the receiving plate 5, it will be guided to the front of the equipment by the arc surfaces of the upper arc portion 8 and the lower arc portion 9, and because the surface area of ​​the arc surfaces of the upper arc portion 8 and the lower arc portion 9 are larger than their back sides, the wind flow rate thereon will also be greater than the wind flow rate on the front side of the photovoltaic panel body 1. According to the principle of atmospheric pressure, it can be known that this forms an air pressure difference between the upper and lower regions, that is, the atmospheric pressure at the arc surfaces of the upper arc portion 8 and the lower arc portion 9 is small, and the atmospheric pressure on the front side of the photovoltaic panel body 1 is large. Therefore, under the influence of atmospheric pressure, the photovoltaic panel body 1 will be pressed on the ground, thereby enhancing the wind resistance effect.

[0026] Finally, the upper arc portion 8 and the receiving plate 5 are integrally formed. The bottom end of the lower arc portion 9 is fixedly connected with a base 10, which is cast from concrete material and has a certain weight and can be fixed on the ground. The base 10 and the upper arc portion 8 are connected to each other by supporting legs 11, which are connected to the upper arc portion 8 by welding, and connected to the lower arc portion 9 by rivets.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
