[0022] The utility model will be described further in detail below in combination with the drawings and specific embodiment.

[0023] Example 1:

[0024] like Figures 1 to 5 As shown, a water ecological aquatic plant planting device for dynamic water environment includes a water baffle 1, which is hinged to a planting plate 2 by a telescopic connecting rod 3. The bottom of the planting plate 2 is provided with a fixing rod 4, and the upstream side of the water baffle 1 is a fish head shape formed by two arc-shaped plates.

[0025] Preferably, the water-blocking plate 1 comprises two parts: a water-facing plate 11 and a water-repelling plate 12. The water-facing plate 11 is a fish-head shape formed by combining two arc-shaped plates, and the water-repelling plate 12 consists of two symmetrically distributed parts. The water-facing plate 11 and the water-repelling plate 12 are connected by a hinge, and the telescopic connecting rod 3 is hinged to the water-repelling plate 12. With this design, the position of the water-repelling plate 12 can be adjusted, which can effectively regulate the flow velocity range in the low-speed zone. Different aquatic plants require different optimal dynamic water conditions to adsorb eutrophic substances, thus improving the adsorption effect of aquatic plants.

[0026] Preferably, the telescopic connecting rod 3 is a three-stage telescopic rod. The telescopic process of the telescopic connecting rod 3 allows the position of the backwater plate 12 to be adjusted, and the three-stage telescopic rod is equipped with internal damping, that is, it will maintain the telescopic length when telescopically extended to different lengths, and its telescopic length can only be changed if subjected to a large force.

[0027] Preferably, the upper surface of the planting plate 2 is evenly provided with a plurality of grooved culture chambers 21, and the planting plate 2 is divided into left and right planting plates, which are connected in the middle by a fixing block 22.

[0028] Preferably, the fixing block 22 has a vertical fixing rod mounting hole 221 that cooperates with the fixing rod 4.

[0029] Preferably, the mounting hole 221 of the fixing rod has slide rails on both sides that mate with the side of the fixing plug 222, and the side of the fixing rod 4 has multiple fixing grooves 42 that mate with the end of the fixing plug 222. In this embodiment, fixing grooves 42 are provided every 1m in height. In this embodiment, the position of the planting board 2 on the surface of the fixing rod 4 can be adjusted, that is, the height of the planting board 2 in the river can be adjusted.

[0030] Preferably, a plurality of protrusions 41 are fixedly welded to the outer bottom of the fixing rod 4. The protrusions 41 can be anchored to the bottom of the river channel, enhancing the anchoring force and enabling the fixing rod 4 to remain upright.

[0031] The specific working principle of this embodiment is as follows:

[0032] When the upstream river water comes, the water flow will first impact the water baffle 1 of the planting device, the water-facing surface of the water baffle 1 is fish head-shaped, and a low-speed area is created for the internal area of the water baffle 1, that is, the planting plate 2 area, which can effectively protect the planting plate 2 and the internal aquatic plants, and adjusting the position of the back baffle 12 can effectively adjust the flow speed range of the low-speed area; different aquatic plants require different optimal water conditions for adsorbing eutrophication substances, and the adsorption effect of the aquatic plants can be improved.

[0033] Embodiment 2:

[0034] The utility model adopts the fluent software similar to the actual to carry out numerical simulation, simulates the upstream water flow speed to be 1 m / s, three different tail water board angle conditions, the flow speed distribution of planting device and surrounding water body. Three tail water board angle schematic diagram and the flow speed distribution of planting device horizontal section as Figures 6 to 9 shown, it can be seen that the flow speed range of the internal area of the water baffle is obviously different when different tail water board angles, the flow speed range is 0.2 m / s~0.6 m / s when-30°, the flow speed range is 0.4 m / s~0.7 m / s when-15°, and the flow speed range is 0.3 m / s~0.6 m / s when 15°, but all are less than the flow speed of surrounding water body and the upstream water flow speed, which proves that the principle of the utility model is feasible.
