Description

Technical Field

[0001] This invention relates to the field of aquaculture, specifically to a wind-powered, temperature-controlled aquaculture device and method based on pumped water storage. Background Technology

[0002] Vigorously developing new energy sources is an important strategic direction for energy development. Wind energy, as an important component of new energy sources with continuously decreasing costs and increasingly mature technology, has received attention from countries around the world.

[0003] my country boasts abundant wind resources and its installed wind power capacity continues to grow, but the problem of wind energy consumption in some areas is becoming increasingly prominent. Consideration is being given to integrating some wind power locally with local agriculture, forestry, animal husbandry, sideline production, and fisheries. Among these, the "wind-fisheries integration" model has received attention and development. Sharing the same waterways for both wind and fisheries can improve resource utilization and ecological benefits.

[0004] Fish survival rates are significantly affected by environmental factors such as weather temperature, and the untimely manual net retrieval also presents challenges, leading to reduced economic benefits for fisheries. Therefore, this paper proposes utilizing wind power to promptly lift fish cages based on weather conditions, ensuring the fish are in a suitable temperature environment and reducing mortality.

[0005] Wind power generation is affected by factors such as wind speed and direction, exhibiting randomness and intermittency. Situations may arise where high temperatures necessitate the lifting of the wind turbine, but low wind speeds prevent the provision of continuous, uniform, and controllable power. Therefore, combining wind power generation with pumped hydro storage is considered to achieve complementary advantages and a stable power supply. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a device and method for timely lifting and lowering aquaculture cages using a combination of wind power and pumped hydropower to achieve temperature-appropriate aquaculture.

[0007] This invention relates to water areas including rivers and oceans, and applicable locations including farmland ponds and deep sea areas. The optimal device design can be selected according to the actual needs of the application location, including the design dimensions of each part and additional accessories.

[0008] The combined operation of wind power generation and pumped storage aims to achieve the goal of the water tank reaching the upper water level line. The wind turbine generates electricity to drive the water pump to pump water, ensuring the water tank's storage capacity. Then, the water tank is used to release water to generate electricity, ensuring a stable output power.

[0009] The aquaculture method uses temperature sensors to determine whether the net cages need to be lowered to keep warm or raised to replenish oxygen, thus achieving suitable temperature for fish farming.

[0010] To achieve the above objectives, the present invention proposes the following technical solution: a wind-powered container lifting device based on pumped-storage energy storage, comprising a wind turbine pumping unit, a water storage unit, a buoyancy device, and a container lifting device. The wind turbine pumping unit includes a wind turbine generator, a tower, a water pump, and a pumping pipe, with the water pump placed inside a water tank. The water storage unit includes a water tank, a water guide pipe, an outlet pipe, an upper water level sensor, a lower water level sensor, a pumping controller, a valve, and a valve controller. The water guide pipe is connected to the water pump and located above the pump. The valve is located at the top of the water guide pipe, and the outlet pipe is connected to the water pump and located outside the water tank. The buoyancy device supports the wind turbine generator tower and the water tank. The buoyancy device includes floats and a connecting bridge. The floats are connected by the connecting bridge, and the center of the connecting bridge coincides with the center of the tower, located below the tower. The container lifting device includes a breeding net cage, a rope, pulleys, a control motor, and a temperature sensor. The rope holds the breeding net cage and is connected to the control motor via the pulleys. The temperature sensor is located above the floats.

[0011] In the aforementioned wind-powered containerized aquaculture device based on pumped storage, the water pump in the pumping section consists of a motor and a water turbine. It functions as a water pump when pumping water and as a water turbine generator when discharging water.

[0012] In the aforementioned wind-powered cage-lifting and temperature-adaptive aquaculture device based on pumped storage, the control motor in the cage-lifting device includes a rope controller, which works in conjunction with a temperature sensor to promptly complete the lifting and lowering of the aquaculture cages.

[0013] This invention also discloses a wind-powered containerized aquaculture method based on pumped hydro storage, the method comprising the following steps:

[0014] When the S1 aquaculture cage does not need to be lowered, the ropes are in a tight state, the upper edge of the aquaculture cage floats on the water surface, the wind turbine generates electricity to drive the water pump to pump water, when the water level reaches the upper water level sensor, the water pump controller controls the water pump to stop pumping water, thus realizing water storage and energy storage.

[0015] When the temperature is low on rainy days, the temperature sensor first sends a signal to the valve controller to release water and generate electricity, and then sends signal 1 to the control motor to release the rope tightening state. Under its own weight and the control of the control motor, the aquaculture cage sinks slowly and in a timely manner to achieve antifreeze and rain protection.

[0016] When the temperature returns to the pre-set ambient temperature line of the temperature sensor, the temperature sensor first sends a signal to the valve controller to release water and generate electricity, and then sends signal 2 to the control motor to retract the rope and lift the aquaculture cage to the rope tightened state.

[0017] The beneficial effects of this invention are: water storage and energy storage can make energy continuous and uniform, making the power generation process controllable, overcoming the shortcomings of randomness and uncertainty in traditional wind power generation; and fully automated timely placement and removal of temperature-controlled aquaculture cages can reduce fish mortality in cold weather and improve economic benefits.

Detailed Implementation

[0022] The wind-powered lifting container temperature-adaptive aquaculture device and aquaculture method based on pumped storage: the wind turbine generator 1 and the tower 2 are coaxial, with the tower 2 serving as a support; the water pump 3 is located inside the water tank 5; and the water pipe 6 is located above the water pump. The wind turbine generator 1 generates electricity to drive the water pump 3, and water enters the water tank 5 from the water pipe 4, realizing wind-powered water lifting.

[0023] The outlet pipe 7 is connected to the water pump 3 and is located outside the water tank 5. The upper water level sensor 8 and the lower water level sensor 9 are located inside the water tank 5. The pump controller 10 receives the signal from the upper water level sensor 8. When the water level reaches the upper water level sensor 8, the pump controller 10 controls the water pump 3 to stop pumping water, thereby realizing water storage and energy storage. When the temperature reaches the pre-set low temperature line or normal temperature line of the temperature sensor, it sends a signal to the valve controller 12, and the valve 11 opens to release water and generate electricity.

[0024] The floating plate 13 is connected to maintain balance by the connecting bridge 14. The center of the connecting bridge 14 is coaxially connected to the center of the tower 2 to achieve stable support.

[0025] Rope 16 is attached to the aquaculture cage 15 and connected to the control motor 18 via pulley 17. When the temperature reaches the pre-set low temperature line of the temperature sensor 19, signal 1 is sent to the controller in the control motor 18 to release the tight state of rope 16 and lower the cage smoothly. When the temperature returns to the pre-set normal temperature line of the temperature sensor 19, signal 2 is sent to the controller in the control motor 18 to tighten rope 16 and raise the cage smoothly.
