[0023] To make the purpose, technical solutions and advantages of the specific embodiments of the present invention clearer, the following will further describe the specific embodiments of the present invention in detail with reference to the drawings. Here, the schematic specific embodiments of the present invention and their descriptions are used to explain the present invention, but do not limit the present invention.

[0024] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides an agricultural, fishery and photovoltaic complementary photovoltaic system to reduce the production cost of the photovoltaic support while ensuring work reliability and durability. The agricultural, fishery and photovoltaic complementary photovoltaic system includes one or more concrete pile foundations 110, a concrete cross beam 120, a plurality of reinforcing plates 130, a plurality of pressing blocks 140 and one or more photovoltaic modules 150, wherein:

[0025] The concrete cross beam 120 is fixedly arranged on the top of one or more of the concrete pile foundations 110; a plurality of the reinforcing plates 130 are arranged in sequence along the top of the concrete cross beam 120 and are fixedly connected to the concrete cross beam 120 through embedded connectors 160: the bottom of the embedded connector 160 is embedded and connected to the concrete cross beam 120, the top protrudes from the concrete cross beam 120 and penetrates and connects to the through hole on the reinforcing plate 130, and the reinforcing plate 130 is pressed and fixed by a fastener 161;

[0026] Each of the photovoltaic modules 150 is placed between two adjacent ones of the reinforcing plates 130 and is fixedly connected to the reinforcing plate 130 through a pressing block 140.

[0027] In specific implementation, there can be various implementation schemes for the connection between the fastener 161 and the embedded connection. For example, as Figure 2 shown, for the convenience of connection and high reliability after installation, to avoid the risk of the photovoltaic module 150 detaching under strong wind conditions, the fastener 161 can be threadedly connected to the embedded connector 160, where: the fastener 161 can be a nut fastener, a thread matching the nut fastener can be provided at the top of the embedded connector 160, and a gasket 162 is provided between the nut fastener and the reinforcing plate 130.

[0028] In specific implementation, there can be various implementation schemes for the setting of the top shape of the concrete crossbeam 120. For example, as Figure 1 shown, an inclined surface facing the light incident direction can be provided at the top of the concrete crossbeam 120. The inclined surface provided at the top of the concrete crossbeam 120 facing the incident direction of the sun rays can effectively improve the light utilization rate of the photovoltaic module 150, thereby increasing the power generation. Further, the inclination angle of the inclined surface can be determined according to the specific longitude and latitude of the project setting location to further improve the light utilization rate. In addition, the concrete crossbeam 120 with an inclined surface has a large contact area with the reinforcing plate 130, and the reinforcing plate 130 has a large contact area with the photovoltaic module 150, so that the inclined beam in the traditional bracket can be replaced, thereby reducing the production cost of the bracket.

[0029] In specific implementation, since the reinforcing plate 130 is inclined along with the concrete crossbeam 120 and the embedded connector 160 is vertically arranged, in order to ensure stable connection, a connection reinforcement structure can also be provided. When setting, there can be various implementation schemes for the selection of the connection reinforcement structure. For example, as Figure 2 shown, the agricultural, fishery and photovoltaic complementary photovoltaic system can further include a spherical gasket 163, the spherical gasket 163 is arranged between the gasket 162 and the reinforcing plate 130, and the spherical surface faces the inclined surface of the concrete crossbeam 120. The setting of the spherical gasket 163 can effectively adapt to the inclination angle between the reinforcing plate 130 and the gasket 162, fill the space, thereby ensuring stable connection.

[0030] In specific implementation, there can be various implementation schemes for the setting of the shape of the reinforcing plate 130. For example, as Figure 1 、 Figure 3 shown, the reinforcing plate 130 can be a rectangular reinforcing plate. Further, in order to reduce costs and avoid safety problems caused by the reinforcing plate 130 protruding from the module, the length of the rectangular reinforcing plate can be less than or equal to the side length of the photovoltaic module 150. At the same time, the width of the reinforcing plate 130 should at least ensure that the frames of two photovoltaic modules 150 can be simultaneously placed on its upper surface, ensuring connection stability while reducing costs, so as to play a role in strengthening the connection.

[0031] In specific implementation, there can be various implementation schemes for the setting of the concrete pile foundation 110. For example, as Figure 3 shown, in order to ensure working stability and durability and reduce the resistance of the concrete pile foundation 110 in water, the concrete pile foundation 110 can be a cylindrical concrete pile foundation. Further, in order to ensure that the concrete cross beam 120 can work stably under extreme working conditions, the bracket can have multiple cylindrical concrete pile foundations, and the multiple cylindrical concrete pile foundations can be arranged at intervals along the concrete cross beam 120 in sequence.

[0032] In specific implementation, there can be various implementation schemes for the selection of the pressing block 140. For example, as Figure 3 shown, the pressing block 140 can be a two-way pressing block, and each of the reinforcing plates 130 simultaneously fixes the sides of two adjacent photovoltaic modules 150 through the two-way pressing block. The setting of the two-way pressing block can effectively reduce the usage amount of the pressing block 140 and improve the installation efficiency at the same time.

[0033] In specific implementation, there can be various implementation schemes for the arrangement of the two-way pressing blocks during setting. For example, as Figure 1 、 Figure 3 shown, each of the reinforcing plates 130 can be provided with two two-way pressing blocks arranged along the side of the photovoltaic module 150, and the two-way pressing blocks are detachably connected to the reinforcing plate 130 through bolts. The two-point connection can effectively improve the connection stability and prevent the photovoltaic module 150 from detaching.

[0034] In specific implementation, there can be various implementation schemes for the setting of the embedded connecting piece 160. For example, as Figure 1 、 Figure 2 shown, the embedded connecting piece 160 can be in an L shape, and the bottom of the L-shaped embedded connecting piece 160 is bent, so as to effectively improve its connection stability with the concrete cross beam 120.

[0035] In specific implementation, there can be various implementation schemes for the setting of the number of the embedded connecting pieces 160. For example, as Figure 1 、 Figure 3 shown, for stable connection, each of the reinforcing plates 130 can be connected to the concrete cross beam 120 through two of the embedded connecting pieces 160, and the two embedded connecting pieces 160 are arranged perpendicular to the extending direction of the concrete cross beam 120.

[0036] In summary, the agro-fishery-photovoltaic complementary photovoltaic system provided by the present invention includes one or more concrete pile foundations 110, a concrete cross beam 120, a plurality of reinforcing plates 130, a plurality of pressing blocks 140, and one or more photovoltaic modules 150. One or more pile foundations are arranged at the bottom of the concrete cross beam 120 to place the concrete cross beam 120 above the water surface. A plurality of reinforcing plates 130 are arranged in sequence along the top of the concrete cross beam 120 and are fixedly connected to the concrete cross beam 120 through embedded connectors 160. The bottom of the embedded connector 160 is embedded and connected to the top of the concrete cross beam 120, and its top protrudes from the concrete cross beam 120 and is connected through a through hole provided on the reinforcing plate 130. At the same time, the top of the embedded connector 160 also has a fastener 161 to press and fix the reinforcing plate 130 to the concrete cross beam 120. Aiming at the defects of high bracket cost, poor reliability, and pollution in production and processing of the existing photovoltaic modules in the agro-fishery-photovoltaic complementary project, the agro-fishery-photovoltaic complementary photovoltaic system creatively uses the concrete pile foundation cross beam structure, avoids the use of traditional steel cross beams and steel inclined beams, further reduces the use of steel connectors, effectively uses concrete materials to replace the steel bracket, and thus greatly reduces the bracket cost while ensuring the working reliability, and also avoids the pollution of the galvanized material to the environment, which is beneficial to the popularization of the agro-fishery-photovoltaic project.
