[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 and Figure 2As shown, a cultivation device for planting seaweed includes a cultivation tank 1, with a cultivation chamber 7 inside the cultivation tank 1. A lifting frame 4 is installed above the cultivation tank 1. The lifting frame 4 has four ends, each of which is Z-shaped. A lifting electric telescopic rod 3 is fixed to the bottom of each end of the lifting frame 4. The lifting electric telescopic rod 3 is fixed to the ground. Four symmetrically distributed fixing rods 5 are fixed to the bottom of the lifting frame 4. A protective outer plate 9 is fixed to the bottom of the fixing rods 5. A planting board 8 is fixed to the inner side of the protective outer plate 9. Multiple drainage holes 10 are provided through the surface of the protective outer plate 9. The drainage holes 10 are arranged in a circular array around the axis of the planting board 8. Soil is filled in the middle of the planting board 8 and seaweed is planted. The protective outer plate 9 surrounds and protects the planting board 8 to prevent soil loss inside the planting board 8. The protective outer plate 9 can also collect the seeds that fall after the seaweed matures.

[0021] A drain pipe 2 is fixed to the shallow surface of the cultivation tank 1. A valve 12 is installed inside the drain pipe 2. The rear end of the drain pipe 2 extends through the cultivation tank 1 into the cultivation chamber 7. The drain pipe 2 is used to release the cultivation water inside the cultivation chamber 7 to achieve the purpose of replacing the cultivation water.

[0022] The outer edge of the protective outer plate 9 is inclined upward at a 15-degree angle, and the protective outer plate 9 is made of rubber. The outer edge of the protective outer plate 9 slides in contact with the inner wall of the cultivation bucket 1. The protective outer plate 9 fills the gap between the planting board 8 and the cultivation bucket 1 to prevent the soil inside the planting board 8 from being lost due to water flow.

[0023] like Figure 3 and Figure 4 As shown, the height difference between the planting board 8 and the bottom of the cultivation bucket 1 is 20 centimeters. Water injection channels 6 are provided on both sides of the cultivation bucket 1. The top of the water injection channel 6 is flush with the upper surface of the cultivation bucket 1. The bottom of the cultivation bucket 1 is close to the bottom of the cultivation bucket 1 and is bent in a U-shape.

[0024] The bottom of the cultivation chamber 7 is provided with two symmetrical water injection holes 11, which are connected to the bottom of the water injection channel 6. Cultivation water is injected into the cultivation chamber 7 through the water injection channel 6. When the cultivation water is injected, the flow rate is reduced by the U-shaped bottom of the water injection channel 6, and it enters the cultivation chamber 7 smoothly from the water injection hole 11. This ensures that the cultivation water will not impact the cultivation soil inside the planting board 8 when it is injected, and will not damage the roots of the seaweed cultivated on the planting board 8.

[0025] Working principle: When cultivating *Ottelia acuminata* using the cultivation device, firstly, cultivation soil is filled in the middle of the planting plate 8. Then, *Ottelia acuminata* seeds are planted in the cultivation soil. Subsequently, cultivation water is added into the cultivation chamber 7 through the water injection channel 6. The cultivation water enters from the top of the water injection channel 6 and reaches the water injection hole 11 from the bottom of the water injection channel 6. Because the bottom of the water injection channel 6 is U-shaped, the flow rate of the cultivation water decreases when passing through the bottom of the water injection channel 6. After entering the cultivation chamber 7, the cultivation water first fills the bottom of the cultivation chamber 7. After filling the bottom of the cultivation chamber 7, the cultivation water comes into contact with the planting plate 8 and the protective outer plate 9 and seeps through the seepage holes 10 on the surface of the protective outer plate 9 to the top of the planting plate 8 and the protective outer plate 9. The cultivation water slowly fills the cultivation chamber 7. During this process, the cultivation water will not affect the cultivation soil in the middle of the planting plate 8. This design prevents erosion, ensuring that the cultivation soil is not washed away by the filling of cultivation water. After the water hyacinth matures, the seeds fall onto the surface of the protective outer plate 9 and gather at the connection between the planting plate 8 and the protective outer plate 9. When workers collect the water hyacinth seeds, they only need to lift the lifting frame 4, the fixing rod 5, and the protective outer plate 9 upwards using the lifting electric telescopic rod 3, so that the protective outer plate 9 is separated from the cultivation water. Workers can then pick up the water hyacinth seeds, improving seed collection efficiency and reducing collection difficulty. At the same time, when changing the cultivation water inside the cultivation chamber 7, the cultivation water inside the cultivation chamber 7 can be drained through the drain pipe 2. During the drainage of the cultivation water, due to the presence of the protective outer plate 9, the water flow will slowly decrease and will not cause erosion or loss of the cultivation soil inside the planting plate 8.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
