Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a fishery-photovoltaic complementary power station system. Background Art

[0002] Since the energy distribution density of photovoltaic power generation is small and requires a huge area, in order to save land use, more and more companies are combining photovoltaics with fisheries, and a large number of photovoltaic power generation projects set up in water have emerged. Taking advantage of the large area occupied by aquaculture, the comprehensive use of aquaculture space is realized. At the same time, photovoltaic panels can also provide shade for fish ponds, especially in the high temperature period of summer. Photovoltaic panels can reduce the temperature of the water area, reduce water evaporation, and reduce the probability of fish and shrimp being scalded to death by water.

[0003] However, the existing fishery solar water photovoltaic projects have the following problems:

[0004] First, installing photovoltaic equipment in aquaculture waters requires first installing pipe pile foundations in the waters, which has high installation costs, long cycles, and causes certain pollution to the aquaculture area;

[0005] Second, the photovoltaic modules installed with pipe pile foundations are fixed in specific locations, which makes it impossible for fishery facilities and equipment to enter to carry out fishery operations. At the same time, the need for fish farmers to regularly purify the water in the fish ponds will also be affected to a certain extent;

[0006] Third, although solar panels can provide shade for fish ponds, they also significantly reduce the light intensity received by the pond surface and the dissolved oxygen content in the pond water, which has a certain negative impact on the physiological activities of fish and phytoplankton.

DETAILED DESCRIPTION

[0041] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0042] like Figures 1 to 8 As shown, a fishery-photovoltaic complementary power station system includes: a photovoltaic module 2, a combiner box 7, a photovoltaic inverter 8, a power distribution cabinet 9, an energy storage battery 10, an energy storage inverter 11 and a load 12;

[0043] The photovoltaic assembly 2 is electrically connected to the combiner box 7;

[0044] The combiner box 7 is electrically connected to the photovoltaic inverter 8;

[0045] The photovoltaic inverter 8 is electrically connected to the power distribution cabinet 9;

[0046] The energy storage battery 10 is electrically connected to the energy storage inverter 11;

[0047] The energy storage inverter 11 is electrically connected to the power distribution cabinet 9;

[0048] The load 12 is electrically connected to the power distribution cabinet 9;

[0049] The power distribution cabinet 9 is electrically connected to the power grid;

[0050] The load 12 includes a plurality of traction motors 3, which are symmetrically fixed on the banks of the aquaculture pond 1 on opposite sides, and a traction roller 4 is installed at the output end of each traction motor 3;

[0051] The traction motor 3 is a brake motor;

[0052] The photovoltaic assembly 2 includes a floating body 204 , and the photovoltaic assembly 2 floats on the water area of ​​the breeding pond 1 through the floating body 204 . The floating body 204 is connected to the traction roller 4 through a traction rope 5 .

[0053] As a specific implementation method, in this embodiment, the photovoltaic module 2 floats on the water surface, and there is no need to install pipe piles in the water area, which can shorten the construction period and reduce water pollution. In this application, the floor area of ​​the photovoltaic module 2 does not exceed half of the area of ​​the water area to which it belongs. When the farmers need to work in the fish pond, they can control the traction motors 3 on both sides to move the position of the photovoltaic module 2.

[0054] In this embodiment, the electric energy generated by multiple photovoltaic modules 2 is transmitted to the junction box 7, which transmits the converged DC power to the photovoltaic inverter 8. The photovoltaic inverter 8 converts the DC power into AC power and transmits it to the distribution cabinet 9. The distribution cabinet 9 configures the electric energy, a part of which is used to charge the energy storage battery 10, a part of which is used for the load 12, and the remaining electric energy is transmitted to the power grid. When there is insufficient light, the distribution cabinet 9 can control the energy storage battery 10 to discharge and provide energy to the load 12. When the electric energy in the energy storage battery 10 is exhausted, the distribution cabinet 9 can control the power grid to directly supply power to the load 12.

[0055] In this embodiment, the load 12 includes the traction motor 3, the oxygen generator 10, and other daily loads required for farming including lighting.

[0056] In this embodiment, the traction motor 3 is a brake motor, which is used to lock the traction rope 5 when the motor loses power to prevent it from moving on the water surface. On the other hand, when encountering strong winds, the traction rope can be used as a cable to prevent the photovoltaic module 2 from being blown over by the strong wind.

[0057] In order to prevent the photovoltaic assembly 2 from being blown over by strong winds, other corresponding designs are also made in the present application. On the one hand, a counterweight block 205 is arranged at the bottom of the inner cavity of the floating body 204 to lower the center of gravity of the photovoltaic assembly 2.

[0058] On the other hand, the photovoltaic assembly 2 also includes a photovoltaic panel 201, an adjustable bracket 202, and a base 203. The photovoltaic panel 201 is mounted on the adjustable bracket 202, the adjustable bracket 202 is mounted on the base 203, and the base 203 is mounted on the floating body 204. The adjustable bracket 202 can adjust the angle of the photovoltaic panel 201. When the wind force is too strong, the angle of the photovoltaic panel 201 can be adjusted to adjust the angle between the photovoltaic panel 201 and the wind direction to an acute angle or zero degree, thereby reducing the impact of the wind force on the photovoltaic assembly 2.

[0059] As a preferred embodiment, there are multiple photovoltaic panels 201 and adjustable brackets 202 , and the multiple photovoltaic panels 201 are arranged in a straight line and installed on the base 203 through the adjustable brackets 202 .

[0060] As a preferred embodiment, in order to reduce the overall weight of the photovoltaic module 2, the base 203 is lightweighted in this application. The base 203 includes a frame 2033, an inclined rod 2031 and a mounting seat 2032; the frame 2033 is a rectangular frame, and there are multiple inclined rods 2031, and every two inclined rods 2031 are cross-fixed in the frame 2033 in a group, and each group is evenly spaced; the mounting seat 2032 is arranged at the intersection of each group of cross inclined rods 2031, and the adjustable bracket 202 is connected to the mounting seat 2032.

[0061] As a preferred implementation, when the photovoltaic panel 201 needs a larger bearing capacity, there are multiple floats 204 , and the multiple floats 204 are evenly installed below the base 203 .

[0062] As a preferred embodiment, it is characterized in that there are multiple photovoltaic components 2, the multiple photovoltaic components 2 are arranged in parallel, and two adjacent photovoltaic components 2 are fixedly connected by a connecting rod 206, and there are multiple connecting rods 206.

[0063] As a preferred embodiment, the existing breeding ponds need an oxygen generator 6 to produce oxygen to ensure the oxygen content underwater, but the oxygen generator 6 needs to be installed on the water surface through a buoy. In this application, the oxygen generator 6 is installed between the connecting rods 206 and installed by using the buoyancy of the photovoltaic module 2, saving the cost of the buoy.
