Description

Technical Field

[0001] The present invention belongs to the technical field of aquatic plant planting, and in particular relates to an assembled aquatic plant planting device. Background Art

[0002] Aquatic plants refer to a general term for plants that can grow in water. Aquatic plants are divided into five major categories: emergent plants, submerged plants, floating plants, floating-leaf plants and wetland plants. They play important roles in purifying water quality, maintaining biodiversity and regulating the water environment.

[0003] The process of planting aquatic plants mainly simulates the natural growth environment, using water, subsoil, light and other conditions to provide plants with the oxygen, water, nutrients and light they need for growth. Container planting is usually adopted, and the aquatic plants are pre-planted in the selected container according to the growth needs and planting density of the plants, and then the container is submerged in water.

[0004] Traditional aquatic plant planting usually involves planting directly in the bottom mud of water bodies or in fixed planting beds to form a whole. After installation, the position is relatively fixed, making it difficult to maintain and replace a single plant.

At this time, the mounting block 14 is stationary through the support rod 11. When the rotating block 12 rotates, the two first nuts 15 move toward the center position as the bidirectional thread groove 13 rotates. At this time, the two fixed blocks 16 enter the middle of the corresponding card groove 101, and the connecting block 19 is fixed by the fixing block 16, so that multiple planting boxes 17 are installed in the middle of the mounting block 14. When the aquatic plants are placed in the water, the cone rod 102 is inserted into the bottom of the water, and the bottom of the fixed rod 1 enters the water.

Through the above structure, a specified number of fixing rods 1 can be connected and fixed to form an overall frame structure, so that the multiple fixing rods 1 can form mutual support, enhance the anti-dumping ability, provide stable support, and be quick and convenient to disassemble, thereby improving maintenance efficiency.

[0027] like Figure 2 and Figure 5 As shown, one side of the planting box 17 is fixed with a connecting seat 4; one end of the connecting seat 4 is fixed with a first magnetic block 41; the other side of the planting box 17 is fixed with a connecting plate 42; the end of the connecting plate 42 is fixed with a second magnetic block 43; when working, when the planting box 17 is installed, the connecting plate 42 on one side of the planting box 17 enters the connecting seat 4 corresponding to the side wall of another planting box 17, and when the end of the connecting plate 42 is close to the first magnetic block 41, the connecting plate 42 is fixed to the inside of the connecting seat 4 by strong magnetic attraction, and the planting box 17 is installed in the middle of the mounting block 14 at the same time. Through the above structure, when multiple planting boxes 17 are installed in the middle of the mounting block 14, an integral structure is formed, so that each planting box 17 supports each other, which can enhance the ability to resist wind and wave and water flow impact, reduce the connection damage of a single planting box 17 due to uneven force in waters with large winds and waves or turbulent water, and maintain overall stability.

[0028] like Figure 4As shown, the top and bottom of the second nut 23 are fixedly connected to a circular plate 5; the inner wall of the circular plate 5 is fixedly connected to a thread brush 51; during operation, when the second nut 23 moves in the middle of the one-way thread groove 21, the circular plate 5 moves synchronously with the second nut 23, and the impurities in the one-way thread groove 21 are cleaned by the thread brush 51.
