Description

Technical Field

[0001] The utility model relates to a plant seedling raising and planting device, in particular to a submerged plant seedling raising and planting device used for flood-carrying rivers in mountainous areas. Background Art

[0002] Tributaries of mountain rivers are usually dry or have low flow rates. However, due to their steep gradients, they are prone to generating large flows during heavy rains, resulting in floods. These floods often rise and fall sharply, with significant fluctuations in flood volume and water level. This water flow has a strong sediment-carrying capacity. Mountain rivers often flow through mountainous or plateau areas, with narrow, winding valleys and steep slopes. During heavy rain seasons, geological disasters such as landslides and debris flows are common. Furthermore, the bed sediments of mountain rivers are mostly gravel and pebbles, which are weathered and broken down from rocks along the riverbanks. These bed sediments are coarse and have a wide gradation distribution. Therefore, after heavy rains, mountain river tributaries are prone to generating large amounts of high-sediment-laden water in a short period of time, resulting in strong sediment transport. This is particularly true in areas affected by earthquakes, where earthquakes generate large amounts of loose solids along the river valleys. This loose solids can migrate and accumulate in the mountain river channels. During heavy rains, these loose solid particles can significantly exacerbate the strong sediment transport in mountain river tributaries.

[0003] When a mountain river's tributaries experience a rapid sediment transport event within a short period of time, a large amount of highly sediment-laden water flows from the tributaries into the mainstream. Due to the presence of flow separation zones and the presence of supporting forces at the confluence of the main and tributary streams, the main stream's sediment-carrying capacity is limited. Therefore, it is difficult or even impossible for the main stream to carry away all the sediment from the tributaries, resulting in sediment accumulation at the confluence. If this severe sediment transport event persists for a long time, the sediment accumulation problem at the confluence will continue to intensify, eventually forming alluvial fans, estuary shoals, mid-channel shoals, or river islands at the confluence. These will severely compress the main stream channel, narrowing the main stream's flow section, reducing the main stream's effective flow area, lowering its flood-carrying capacity, and even causing sudden changes in the main stream's flow path. All of these factors will reduce the flood control capacity of existing levees and affect the safety of the river channel. Strong sediment transport can alter riverbed topography and flow conditions at the confluence of main and tributary rivers and in upstream and downstream reaches. In severe cases, this can lead to the formation of dams and barrier lakes, inundating upstream farmland, roads, railways, and riverside structures, causing widespread disasters. Currently, there are no reports on disaster mitigation measures for confluences of main and tributary rivers in mountainous areas under strong sediment transport conditions. Developing methods to alleviate sediment blockage at confluences of main and tributary rivers in mountainous areas would have significant implications for flood safety in mountainous river channels.

[0004] Submerged plants are an important part of aquatic ecosystem restoration. They not only provide more habitats and shelter for aquatic animals, but also increase dissolved oxygen in the water, purify water quality, and expand the effective living space of aquatic animals. At the same time, the young and tender parts of submerged plants can be eaten by aquatic animals and birds, thereby improving the entire aquatic ecosystem. The role of submerged plants in water ecological restoration, especially in improving water visibility and landscape creation, is increasingly receiving attention. Common submerged plants include Vallisneria, Hydrilla verticillata, and Potamogeton serrata. Common planting methods use artificial methods such as cuttings and broadcasting. However, the survival rate of traditional cuttings and broadcasting methods in flood channels in mountainous areas is still low, resulting in a certain amount of waste of resources and construction costs.

[0007] The plant planting frame structure comprises an outer end connecting frame arranged on the inner side of each limiting and fixing partition body and a seedling positioning clamp evenly distributed on each outer end connecting frame.
