Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic component bracket for complementary fishing and light. Background Art

[0002] With the continuous growth of global energy demand and the gradual strengthening of environmental protection awareness, renewable energy has gradually become the mainstream. Among them, solar energy, as a clean and renewable energy, has received widespread attention and application. However, traditional solar power generation methods have problems such as low land resource utilization and great ecological impact. In order to solve these problems, a new type of solar power generation method - "fish-light complementarity" came into being.

[0003] Fishery-solar complementarity refers to a model that combines fishery farming with photovoltaic power generation by building solar photovoltaic power stations on the surface of fishery farming water. This model can make full use of the spatial resources of the fishery farming surface, improve land utilization, and reduce damage to the ecological environment. The fishery-solar complementarity model has received widespread attention and application in my country, especially in freshwater farms in the southeast coastal areas.

[0004] In the fish-photovoltaic complementary model, the highest risk of component equipment is lightning risk, and increasing the density of vertical discharge channels is the best measure to reduce lightning risk. Conventional photovoltaic area grounding generally adopts an onshore photovoltaic grounding structure, forming a large-area connected grounding network through horizontal grounding electrodes + vertical grounding electrodes. On the basis of the onshore photovoltaic grounding structure, in order to reduce the risk of photovoltaic components being exposed to lightning, it is necessary to increase the density of vertical discharge channels and vertical grounding electrodes. However, the denser the vertical grounding electrodes are set, the higher the cost, which is not suitable for promotion and use. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a photovoltaic component support for fishery-light complementation which is low in cost and can reduce the risk of lightning.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a fish-light complementary photovoltaic component bracket, including purlins, inclined beams, adjusting rods, welded bottom plates and PHC pipe piles connected in sequence from top to bottom, the PHC pipe piles including a pipe body and a top end plate, steel bars are arranged in the pipe body, and the purlins, inclined beams, adjusting rods, welded bottom plates, top end plates and steel bars are electrically connected in sequence.

[0007] Wherein, the photovoltaic components are arranged on the purlins.

[0008] Wherein, the purlin is connected to the inclined beam by bolts, and the inclined beam is connected to the adjusting rod by bolts.

[0009] It also includes a front support plate, a rear support plate and a hoop, one end of the front support plate and the rear support plate are connected to the inclined beam, and the other end of the front support plate and the rear support plate are connected to the hoop and are installed on both sides of the PHC pipe pile through the hoop.

[0010] Wherein, it also includes a diameter-increasing rib, and two ends of the diameter-increasing rib are respectively connected to the adjusting rod and the welding bottom plate.

[0011] Wherein, the steel bars include stirrups and stress main bars connected to each other, and the stress main bars are welded to the top end plate.

[0012] The beneficial effects of the utility model are as follows: the photovoltaic component bracket for fishery-photovoltaic complementation of the utility model is reliably connected, easy to construct, highly economical, and reduces the risk of lightning in the fishery-photovoltaic complementation mode. The photovoltaic component bracket for fishery-photovoltaic complementation forms a reliable equipotential between the inclined beam assembly, the adjusting rod, the welding bottom plate, the top end plate, and the steel bars by sequentially electrically connecting the purlins, the inclined beams, the adjusting rods, the welding bottom plate, and the PHC piles; the PHC piles are vertically driven into the bottom of the water area, and the steel bars in the PHC piles can be used as vertical grounding electrodes, becoming a discharge channel for lightning currents, and the external concrete-water is regarded as soil with a low resistivity for grounding, thereby reducing the risk of lightning and ensuring the stable operation of the photovoltaic power generation system.

[0018] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0019] Please refer to Figures 1 to 3The support for the photovoltaic module of fish-light complementary relationship includes purlins, inclined beams, adjusting rods, welded bottom plates and PHC pipe piles connected in sequence from top to bottom. The PHC pipe piles include a pipe body and a top end plate. Steel bars are arranged in the pipe body. The purlins, inclined beams, adjusting rods, welded bottom plates, top end plates and steel bars are electrically connected in sequence.

[0020] The inclined beam is specifically a component having an angle between the axial direction and the horizontal plane.

[0021] From the above description, it can be seen that the beneficial effect of the utility model is that the standard PHC pile is a pile formed by pouring concrete into a steel cage. Due to its concrete structure, the resistivity of the PHC pile in water is very low, approximately 40-55Ω·m, slightly less than the resistivity of the water body. In the utility model, a reliable equipotential connection is formed between the inclined beam assembly, the adjustment rod, the welded bottom plate and the PHC pile, and then the PHC pile is vertically driven into the bottom of the water area. At this time, the steel bars in the PHC pile can be used as a vertical grounding electrode, which becomes a discharge channel for lightning current. The external concrete-water is regarded as soil with low resistivity to achieve grounding, thereby reducing the risk of lightning and ensuring the stable operation of the photovoltaic power generation system.

[0022] The photovoltaic component bracket of the utility model is reliable in connection, easy to construct, and highly economical. Compared with the solution of setting up a dedicated down conductor + vertical grounding electrode, it can greatly reduce the amount of project materials and construction work, and reduce costs; compared with setting up a dedicated down conductor steel bar in the PHC pile, the utility model only needs to use conventional PHC piles required by the national standard, reducing the additional delivery cycle and cost of customizing PHC piles.

[0023] Furthermore, the cross section of the adjusting rod is a rectangle with an opening on one side.

[0024] Furthermore, the photovoltaic components are arranged on the purlins.

[0025] Furthermore, the purlin is connected to the oblique beam by bolts, and the oblique beam is connected to the adjusting rod by bolts.

[0026] Furthermore, it also includes a front support plate, a rear support plate and a hoop, one end of the front support plate and the rear support plate are connected to the inclined beam, and the other end of the front support plate and the rear support plate are connected to the hoop and installed on both sides of the PHC pipe pile through the hoop.

[0027] From the above description, it can be seen that the connection and fixation of the inclined beam are achieved through the front support plate, the rear support plate and the hoop, the inclination of the inclined beam is maintained, and the solar energy is utilized to the maximum extent.

[0028] Furthermore, it also includes a diameter-increasing rib, and two ends of the diameter-increasing rib are respectively connected to the adjusting rod and the welding bottom plate.

[0029] It can be seen from the above description that the increased diameter rib can ensure that the adjusting rod and the welding base plate are firmly connected.

[0030] Furthermore, the reinforcement includes stirrups and stress main bars connected to each other, and the stress main bars are welded to the top end plate.

[0031] Please refer to Figures 1 to 3 Embodiment 1 of the utility model is: a photovoltaic assembly bracket for fish-light complementary, comprising a diameter-enhanced rib 1, a front support plate 2, a rear support plate 3 and a clamp 4, as well as a purlin 5, an inclined beam 6, an adjusting rod 7, a welded bottom plate 8 and a PHC pile 9 connected in sequence from top to bottom, the PHC pile 9 being buried 3 to 7 m deep in the pond, and the cross section of the adjusting rod 7 being a rectangle with an opening on one side.

[0032] The purlin 5 is connected to the inclined beam 6 by bolts, and the photovoltaic module 10 is fixed to the purlin 5 by bolts. The inclined beam 6 is connected to the adjustment rod 7 by bolts, and the two ends of the increased diameter rib 1 are connected to the adjustment rod 7 and the welding bottom plate 8 respectively.

[0033] One end of the front support plate 2 and the rear support plate 3 are connected to the inclined beam 6 by bolts, and the other ends of the front support plate 2 and the rear support plate 3 are connected to the clamp 4 and installed on both sides of the PHC pipe pile 9 through the clamp 4. The PHC pipe pile 9 includes a pipe body 91 and a top end plate 92. The pipe body 91 is provided with steel bars, and the steel bars include stirrups and stress main bars connected to each other; the welded bottom plate 8 and the top end plate 92 are fully welded, and the top end plate 92 and the stress main bars are fully welded. The purlin 5, the inclined beam 6, the adjusting rod 7, the welded bottom plate 8, the top end plate 92 and the stress main bars are electrically connected in sequence.

[0034] In summary, the photovoltaic component support for fishery and photovoltaic complementation provided by the utility model electrically connects the purlin 5, the inclined beam 6, the adjusting rod 7, the welded bottom plate 8, the top end plate 92 and the steel bars in sequence, so that a reliable equipotential is formed between the inclined beam 6 component, the adjusting rod 7, the welded bottom plate 8 and the PHC pile 9; the PHC pile 9 is inserted into the water, and its stress main reinforcement can be used as a vertical grounding electrode, becoming a discharge channel for lightning current, and the stirrups are used to increase the strength of the PHC pile 9; the external concrete-water can be regarded as soil with low resistivity to achieve grounding, thereby playing a role in reducing the risk of lightning, and the economy is relatively high. At the same time, the diameter-enhanced rib 1 is used to reinforce the adjusting rod 7 and the welded bottom plate 8, and the connection and fixation of the inclined beam 6 are achieved through the front support plate 2, the rear support plate 3 and the hoop 4, so that the inclination of the inclined beam 6 can be maintained, and the solar energy can be used to the maximum extent.
