Abstract
Description
Technical Field
[0001] This utility model relates to the field of ecological environment restoration technology, specifically to a device for planting aquatic plants in still water environments. Background Technology
[0002] Aquatic plants' roots can absorb eutrophic substances in the water, such as total phosphorus, ammonia nitrogen, and organic matter, thus transferring nutrients from the water body and mitigating water pollution and eutrophication caused by closed or insufficient self-circulation. Therefore, people often plant aquatic plants in rivers to improve the river's aquatic ecological environment. However, to avoid the problem of excessive growth of aquatic plants, it is necessary to use planting devices to release aquatic plants into the river water. However, in still water environments, the growth of plants and the efficiency of their nutrient absorption are not high. The literature "The Influence of Submerged Plant Growth on Phosphorus Migration in Overlying Water and Sediments under Still and Flowing Water Conditions, Environmental Science Research, 2023, 36(05):975~985" explores the influence of Vallisneria natans and Hydrilla verticillata on phosphorus migration in overlying water and sediments under still and flowing water (v=0.10m / s) conditions, and finds that flowing water can promote the growth of submerged plants and phosphorus absorption. Therefore, we propose a planting device for aquatic plants in still water environments. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned shortcomings. This invention provides a water ecological aquatic plant planting device for still water environments to improve the growth efficiency of plants and the absorption efficiency of their nutrients.
[0004] This utility model is achieved through the following technical solution: a water ecological aquatic plant planting device for still water environment, including a fixing device, the fixing device including a protective tube, the inside of the protective tube being rotatably connected to the rotating shaft of the rotating device, the top of the rotating shaft being connected to the center of the wind turbine above the water surface, the bottom of the rotating shaft being connected to the center of the impeller below the water surface, the protective tube area corresponding to the impeller having a hollow structure, and the bottom of the protective tube being fixedly connected to the planting board.
[0005] Preferably, the upper surface of the planting plate has multiple uniformly spaced grooved culture chambers.
[0006] Preferably, the bottom of the protective tube is connected to the center of the planting board support frame. The protective tube is hollow and has perforated layers on the upper and lower sides of the planting board support frame. The perforated layer on the upper side corresponds to the position of the impeller. The bottom of the protective tube passes through the center of the planting board support frame and is connected to the anchor rod of the conical structure. Multiple support bars are provided on the outside of the planting board support frame, and the support bars pass through the support frame groove opened inside the planting board.

[0008] Preferably, the protective tube is rotatably connected to the rotating shaft of the rotating device via a bearing.
[0009] The beneficial effects of this utility model are:
[0010] The wind turbine of this invention rotates under the action of wind, which in turn drives the impeller to rotate. The impeller is located underwater, and its rotation causes the surrounding water to move, creating dynamic water conditions. Under the influence of flowing water, the growth of submerged plants in the planting board and the absorption of phosphorus can be promoted. This can improve the effect of aquatic plant roots in absorbing eutrophic substances in the water, thereby improving the plant growth efficiency and the absorption efficiency of nutrients. This invention can rationally plant plant types according to the water flow velocity around the impeller, while simultaneously increasing the oxygen content of the water to further purify the water. This planting device is easy to prepare, inexpensive, and suitable for large-scale production. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0020] Example 1:
[0021] like Figures 1 to 7 As shown, a water ecological aquatic plant planting device for still water environments includes a fixing device 1. The fixing device 1 includes a protective tube 11, which is rotatably connected to the rotating shaft 23 of a rotating device 2. The top of the rotating shaft 23 is connected to the center of a fan 21 above the water surface, and the bottom of the rotating shaft 23 is connected to the center of an impeller 22 below the water surface. The area of the protective tube 11 corresponding to the impeller 22 has a hollow structure, and the bottom of the protective tube 11 is fixedly connected to a planting plate 3. In this embodiment, the fan 21 located above rotates when the wind blows, thereby causing the rotating shaft 23 to rotate, which in turn drives the impeller 22 below to rotate, thus causing water flow. Under the influence of the flowing water, the growth of submerged plants and phosphorus absorption in the planting plate 3 can be promoted.
[0022] Preferably, the upper surface of the planting board 3 has multiple uniformly spaced grooved culture chambers 31. In this embodiment, the grooved culture chambers 31 are used to cultivate submerged plants.
[0023] Preferably, the bottom of the protective tube 11 is connected to the center of the planting board support frame 12. The protective tube 11 is hollow and has perforated layers 111 on the upper and lower sides of the planting board support frame 12. The perforated layer 111 on the upper side corresponds to the position of the impeller 22. The bottom of the protective tube 11 passes through the center of the planting board support frame 12 and is connected to the anchor rod 112 of the conical structure. Multiple support bars 121 are provided on the outer side of the planting board support frame 12. The support bars 121 pass through the support frame groove 32 opened inside the planting board 3. In this embodiment, the bottom of the protective tube 11 is connected to the center of the planting board support frame 12, and the support bars 121 of the planting board support frame 12 pass through the support frame groove 32 opened inside the planting board 3. Therefore, the protective tube 11 is finally fixedly connected to the planting board 3. The planting board 3 itself is submerged in water and in contact with the bottom of the riverbed. The anchor rod 112 can anchor the entire planting board 3 to the bottom of the riverbed, thereby fixing the entire device.
[0024] Preferably, the outer end of the support bar 121 is provided with an installation groove 122, and the outer side of the planting plate 3 is provided with a fixing crossbar groove 33, which cooperates with the fixing crossbar 4. The inner side of the fixing crossbar 4 is provided with a protruding component 41, which cooperates with the installation groove 122. Through the cooperation of the protruding component 41 and the installation groove 122, the connection between the support bar 121 and the planting plate 3 is made more stable.
[0025] Preferably, the protective tube 11 is rotatably connected to the rotating shaft 23 of the rotating device 2 via a bearing. This design limits the rotation shaft 23 without affecting its rotational movement inside the protective tube 11.
[0026] The specific working principle of this embodiment is as follows:
[0027] The bottom of the protective tube 11 is connected to the center of the planting board support frame 12, and the support bar 121 of the planting board support frame 12 passes through the support frame groove 32 opened inside the planting board 3. Therefore, the protective tube 11 is finally fixedly connected to the planting board 3. The planting board 3 itself is submerged in the water and in contact with the bottom of the riverbed. The entire planting board 3 can be anchored to the bottom of the riverbed by the anchor rod 112, thereby fixing the entire device. The wind fan 21 located above keeps rotating when the wind blows, thereby causing the rotating shaft 23 to rotate, which in turn drives the impeller 22 below to rotate, thereby driving the surrounding water to move and creating dynamic water conditions. Under the influence of the flowing water, the growth of submerged plants in the planting board 3 and the absorption of phosphorus can be promoted.
[0028] Example 2:
[0029] As attached Figure 8 As shown, this utility model uses Fluent software, which is similar to reality, to perform numerical simulation of the phenomenon of the impeller rotation driving the movement of the surrounding water. By observing the velocity distribution diagram, it can be seen that the flow velocity is higher near the impeller and lower further away from the impeller. Plants can be planted reasonably according to the flow velocity distribution.

The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
