[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example 1

[0023] Ecological floating islands are a type of water treatment technology that utilizes nutrients in the water to allow plants to grow on the water surface. Ecological floating island technology involves artificially transplanting aquatic plants or modified terrestrial plants onto floating islands. The plants absorb nutrients such as nitrogen and phosphorus from the water through their root systems, thereby remediating polluted water in situ and achieving purification.

[0024] This embodiment provides a floating island shrimp farming device specifically for freshwater prawns, comprising a floating island 500, a planting area 400 located on the upper part of the floating island 500, and a farming area 300 located at the lower part of the floating island 500, used for raising freshwater prawns. The floating island also has a pontoon 200, and a solar tower 100 is installed inside the floating island 500. The solar tower 100 contains a solar power generation system for power supply and storage space. The area between the solar tower 100 and the pontoon 200 is the planting area 400, whose frame is constructed of alloy steel. The planting area 400 has planting floats for planting plants, mainly aquatic plants such as water canna, water lily, calamus, variegated reed, green rush, pickerelweed, water caltrop, and water lily. The planting floats have a detachable structure. A spiral propulsion device is fixed to one side of the wire mesh of the farming area 300, and the control device for the spiral propulsion device is located inside the solar tower 100. There is a certain amount of space between the bottom of the floating island and the 300-meter horizontal level of the aquaculture area.

[0025] Furthermore, the solar power generation system includes solar photovoltaic panels, batteries, and a transformer. The solar photovoltaic panels are electrically connected to the batteries, and the batteries are connected to the transformer. The solar photovoltaic panels are installed on the outer wall of the solar tower 100, while the batteries and transformer are located in the power supply room at the top of the solar tower. The storage room houses the storage cylinders, feeding machine, and oxygen generator. The transformer is connected to the power supply terminals of the feeding machine and oxygen generator. The power supply room also contains a control cabinet, whose power supply terminal is connected to the transformer.

[0026] The floating island shrimp farming equipment provided by this invention is designed specifically for freshwater prawns. Shrimp farming and plant cultivation are independently separated but integrated within the system. It is very convenient to use in lakes, rivers, and large ponds, facilitating centralized farming management, precise feeding and environmental control of freshwater prawns, and simple harvesting. It produces high-quality shrimp with high yield per unit area. Plant growth improves the water environment and surface environment of lakes, rivers, and large ponds, creating a micro-ecosystem, establishing a micro-environmental ecological cycle, and reducing environmental problems in aquaculture. It has great market promotion and application value. Example 2

[0027] Plants grow through hydroponics, typically by adding specialized nutrient solutions to water bodies. This direct supplementation of available elements meets the plant's absorption needs, ensuring its growth and reproduction. However, in lakes, rivers, and large ponds, the nutrients present are diverse in form and distribution, with only a small portion directly absorbable by aquatic plants for growth. For example, the available phosphorus content in water is generally only about 0.16% of the total phosphorus content. Therefore, direct hydroponics is not suitable and cannot effectively solve the problem of eutrophication.

[0028] This embodiment provides a floating island shrimp farming device specifically for freshwater prawns. Unlike the previous embodiments, the planting floating plate is modified to allow the planted aquatic plants to simultaneously receive nutrients from both soil and hydroponics, optimizing nutrient circulation within the floating island. Specifically, the planting floating plate has a filler-filling space, internally divided into a filler layer 401-1 and a water-passing layer, with the water-passing layer at the top. The filler layer 401-1 is filled with filler material, and each filler layer 401-1 receives the filler material through a receiving plate 401-3. When only a single filler layer 401-1 is used, the bottom surface of the planting floating plate can receive the filler material. The filler material is soil suitable for the growth of aquatic plants.

[0029] Furthermore, the receiving plate 401-3 includes a frame, with a layer of blocks tightly arranged in the middle of the frame by friction, and a certain gap is maintained between the receiving plate 401-3 and the filler below. Example 3

[0030] This embodiment provides a floating island shrimp farming device specifically for freshwater prawns. Unlike the previous embodiment, a water hammer chamber is also provided in the lower part of the packing layer 401-1. A water hammer pipeline structure 600 is provided in the water hammer chamber. The water hammer pipeline structure 600 uses high-speed water flow in the pipeline to push the packing and release effective nutrients suitable for plant growth.

[0031] The water hammer pipeline structure 600 includes a water flow chamber 601 and pipes. One end of a first inlet pipe 602 is connected to an external water body or an external water pump, while the other end is connected to the water flow chamber 601 at a lower height, creating a drop. Along the direction of the first inlet pipe 602, an outlet pipe 603 is provided on the other side of the water flow chamber 601. A first intelligent inlet valve is provided between the water flow chamber 601 and the first inlet pipe 602, and a second intelligent outlet valve is provided between the water flow chamber 601 and the outlet pipe 603. A first outlet pipe 604 is provided from the water flow chamber 601 towards the packing material. A first intelligent quick valve is provided at the connection between the first outlet pipe 604 and the water flow chamber 601, and a first intelligent outlet valve is provided after the first intelligent quick valve. The first intelligent inlet valve, the first intelligent quick valve, the first intelligent outlet valve, the second intelligent outlet valve, and the external water pump are all controlled via an intelligent terminal. Water flows into the water hammer pipeline structure 600, and the intelligent terminal quickly controls the valve to switch, creating a water hammer effect in the water flow chamber 601. The resulting high-pressure water body will impact out through the first outlet pipe 604. Preferably, the first outlet pipe 604 is set towards the block connection of the receiving plate 401-3.

[0032] Furthermore, each packing layer is equipped with a receiving plate for replacement. The water hammer pipe outlet of the water hammer pipe structure 600 faces the block in the middle of the frame of the receiving plate 401-3. After the equipment has been used for a period of time, by controlling an external water pump, the water hammer pipe impacts the packing, thereby disrupting the tight arrangement of the blocks until they collapse, causing the blocks and the packing above them to fall and rearrange, thus changing the facing surface of the packing and the water flow, and promoting the release of nutrients in the packing.

[0033] Ideally, the upper part of the filler layer is a thick nutrient soil, and the lower part is a lightweight filler for support, such as fly ash or lightweight gravel. This supports the soil and plants above and prevents the floating island from sinking due to excessive weight. At the same time, the lightweight filler at the bottom can better exert the water hammer effect.

[0034] Ideally, the lower outer wall of the planting float, corresponding to the area below the filler layer, is provided with through holes. The lightweight filler retains nutrients in the water, especially particulate matter, which are then transformed and decomposed over time, increasing the effective content of nutrients. After being disturbed by water hammer operations, the effective nutrients are preferentially released to the aquatic plant area, promoting plant growth and improving the eutrophication state of the water.

[0035] The planting area of ​​this invention is directly connected to the lake water, and a special floating platform for vegetable cultivation is placed above the water. Since vegetables can be grown on the floating island, they will draw nutrients from the aquaculture area below the floating island during their growth process, thus meeting their growth needs. In addition, the vegetable cultivation on the floating island also has a certain purifying effect on the water in the aquaculture area below the floating island.

[0036] The aquaculture area of ​​this invention can gather fish, increasing yield. Fish, shrimp, and crabs are cultured in the lower part of the floating island. Designated aquaculture areas in the lower part of the floating island prevent the fish, shrimp, and crabs from wandering away. Furthermore, this invention separates the fish, shrimp, and crabs for aquaculture; fish can be cultured in the inner aquaculture area of ​​the lower part of the floating island, while shrimp and crabs can be cultured in the outer aquaculture area. When harvesting fish, the upper floating island and the underwater aquaculture area can be separated, allowing this invention to be used flexibly according to the scenario; however, it is typically used as a single unit. Example 4

[0037] like Figure 3 As shown, the solar power generation system includes solar photovoltaic panels, batteries, and transformers. The solar photovoltaic panels are installed on the outer wall of the solar tower, and the batteries and transformers are installed in the power supply room. The power supply room also has a control cabinet. The storage room houses the storage cylinder, feeder, and oxygen generator. The solar photovoltaic panels are electrically connected to the batteries, the batteries are connected to the transformer, and the transformer is connected to the power supply terminals of the feeder, oxygen generator, control cabinet, water hammer system, and smart terminal.

[0038] The principle of a solar power generation system is as follows: solar photovoltaic panels convert light energy into electrical energy, which is then output to a storage battery for energy storage. When power is needed, the storage battery outputs its internal electrical energy to a transformer, which converts the direct current into alternating current and then outputs it to power the feeder, oxygen production equipment, control cabinet, water hammer system, smart terminal, etc.

[0039] This invention enables automated, timed, and quantitative feeding of fish using a storage hopper and a feeder, and is simple to operate. The floating island of this invention features a water-impact structure at the bottom of the planting board, allowing aquatic plants to better absorb nutrients such as nitrogen, phosphorus, and organic matter from the water. This helps improve eutrophication, promotes the reproduction of fish and shrimp, and ensures a stable and balanced ecosystem within the aquatic environment.

[0040] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the invention. The scope of the present invention is defined by the appended claims and their equivalents.
