Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a distributed photovoltaic power generation device. Background Technology

[0002] Distributed photovoltaic (PV) power generation specifically refers to PV power generation facilities built near user sites, operating on a model where the user consumes the generated electricity themselves, with any surplus electricity fed into the grid. In distributed PV power generation, the surplus electricity needs to be fed into the grid using a grid-connected box, which is the device that transmits the electricity generated by distributed PV power generation to the power grid. During use, the grid-connected box for distributed PV power generation is typically installed on the exterior wall of a building. The distributed PV power generation equipment is connected to the grid-connected box via cables, and the grid-connected box is then connected to the power grid via cables, thus achieving grid connection.

[0003] Photovoltaic modules are usually fixed to the bracket with nuts. Over time, some of the nuts may come loose. In windy weather, the photovoltaic modules may fall off and cause damage.

[0004] Therefore, it is necessary to invent a distributed photovoltaic power generation device to solve the above problems. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4The distributed photovoltaic power generation device shown includes a base 1, a windproof mechanism 2 above the base 1, the windproof mechanism 2 including a reinforcing groove 201 formed on the surface of the base 1, a connecting plate 202 above the base 1, a reinforcing block 203 fixedly connected to the bottom end of the connecting plate 202 and sliding inside the reinforcing groove 201, a windproof wall 208 fixedly connected to the top end of the connecting plate 202, the outer side of the windproof wall 208 having an arc, and the inner side wall of the windproof wall 208 having a... A wear-resistant outer shell 204 is engaged within a slot, and a filling plate 207 is wrapped inside the wear-resistant outer shell 204. The curvature of the windbreak wall 208 changes the direction of the wind blowing on its surface, thereby reducing the wind load. Several sets of support plates 205 are inserted into the surface of the reinforcing groove 201. The top of the support plate 205 is fixedly connected to the back side of the wear-resistant outer shell 204, thereby reinforcing and supporting the wear-resistant outer shell 204 and the windbreak wall 208. One side of the support plate 205 is threaded with... Side nails 206 penetrate one side of the support plate 205 and are threadedly connected to the connecting plate 202, further reinforcing the connection. The top of the base 1 has several sets of mounting threaded holes 4 arranged in a ring around the center of the base 1. Mounting screws 6 are threaded into the interior of the mounting threaded holes 4, penetrating the bottom of the connecting plate 202 and threadedly connected to it. The mounting threaded holes 4 and mounting screws 6 work together to adjust and limit the position of the connecting plate 202. The base 1 cooperates with the windproof mechanism 2, and the connecting plate 202 supports components such as the windproof wall 208. The connection between the connecting plate 202 and the base 1 is reinforced by the cooperation of the reinforcing groove 201 and the reinforcing block 203. The windproof wall 208 is further reinforced by the cooperation of the wear-resistant shell 204 and the support plate 205. Finally, the curvature of the windproof wall 208 changes the direction of the wind blowing on its surface, thereby reducing wind load and improving the stability of the structure.

[0025] Refer to the instruction manual appendix Figure 1-4A protective seat 3 is fixedly connected to the top of the base 1, and an adjusting seat 101 is fixedly connected to the top of the base 1. A photovoltaic panel mounting bracket 5 is fixedly connected to the top of the adjusting seat 101. The protective seat 3 further protects the adjusting seat 101. Several sets of air outlet slots 7 are opened on the top of the windbreak wall 208. The bottom of the air outlet slots 7 communicates with a turbulence channel 8, and the turbulence channel 8 is opened on the surface of the windbreak wall 208. By cooperating with the curvature of the windbreak wall 208, the air blowing towards the windbreak wall 208 can be guided to other places. Several sets of first air guide blocks 9 are fixedly connected to the surface of the windbreak wall 208. Several sets of second air guide blocks 10 are connected. The first air guide block 9 and the second air guide block 10 are distributed in opposite directions and are staggered. The shape is adjusted by the cooperation of the first air guide block 9 and the second air guide block 10, thereby changing the vortex wind field around the component and reducing wind vibration. Through the cooperation of the first air guide block 9, the second air guide block 10 and other parts, the shape of the surface of the windbreak wall 208 is changed by the cooperation of the first air guide block 9 and the second air guide block 10, thereby changing the vortex wind field around the component, so as to achieve a turbulence effect and reduce wind vibration. In addition, the air outlet slot 7 and the turbulence slot 8 are used to guide the turbulent wind out of the windbreak wall 208, thereby avoiding direct wind blowing.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-4 When wind protection is required for the photovoltaic panel mounting frame 5, one or more sets of connecting plates 202 are installed on the surface of the reinforcing groove 201 through the cooperation of the mounting threaded holes 4 and mounting screws 6. When the wind blows towards the photovoltaic panel mounting frame 5, the curvature of the windbreak wall 208 changes the direction of the wind blowing on the surface of the windbreak wall 208, thereby reducing the wind load and improving the stability of the structure. The connection between the support plate 205 and the connecting plate 202 is reinforced by the side nails 206, and then the connection between the connecting plate 202 and the wear-resistant shell 204 is reinforced by the support plate 205. Finally, the wear-resistant shell 204 reinforces the support for the windbreak wall 208, thereby improving the stability of the structure. Qualitatively, when wind blows across the surface of the windbreak wall 208, the shape of the windbreak wall 208 surface is first altered by the cooperation of the first air guide block 9 and the second air guide block 10, thereby changing the vortex wind field around the component. This guides the wind along the surface of the windbreak wall 208, further changing its direction to achieve a turbulence effect, thus reducing wind vibration. In conjunction with the air outlet trough 7 and the turbulence trough 8, the turbulent wind is guided out of the windbreak wall 208, thus avoiding wind vibration caused by direct wind blowing, further protecting the photovoltaic panel mounting frame 5. After the photovoltaic panel mounting frame 5 is installed, sunlight shines on the photovoltaic modules of the photovoltaic panel mounting frame 5, and the photovoltaic effect converts light energy into direct current (DC). Subsequently, the DC is converted into alternating current (AC) by an inverter to meet the needs of local loads or grid connection.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
