Description

Technical Field

[0001] The utility model belongs to the field of water ecological restoration, and specifically relates to a device for restoring submerged plants in lakes and reservoirs. Background Art

[0002] In recent years, due to the dual influence of natural evolution and human activities, a large amount of organic matter has accumulated in lakes and reservoirs. The decomposition of these organic matter brings a large amount of nutrients, causing algae outbreaks, reduced transparency, and death of aquatic plants in the lake and reservoir areas. The ecological problems are serious. If not resolved, it will lead to waste of water resources and further damage to the water ecological environment.

[0003] The traditional method of lake and reservoir water ecological restoration uses chemicals to control algae, then directly plants aquatic plants after catching herbivorous fish, which has a great impact on aquatic animals. However, pollutants continue to accumulate, nutrient concentrations increase, and algae are prone to recurrence, forming a shielding effect, resulting in reduced transparency, and the bottom light intensity is lower than the photosynthetic compensation point, causing the death of submerged plants. At the same time, fish from tributaries flowing into lakes and reservoirs enter the lakes and reservoirs to graze, resulting in unsustainable water ecological restoration effects, and it is difficult to achieve the ideal lake and reservoir water ecological restoration effect.

It should be understood that the implementation examples described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0020] like Figure 1 A device for restoring submerged plants in lakes and reservoirs comprises multiple rows of vertical support rods 1 whose bottom ends are buried in the lake bottom, the top ends of the vertical support rods 1 are exposed above the water surface and the height of the top ends of the vertical support rods is not lower than the design flood level, the bottom ends of the vertical support rods 1 are embedded in the mud to a depth not lower than the height above the mud, and transverse fixing rods 2 are arranged between each adjacent vertical support rod 1 on each row of vertical support rods 1, and the transverse fixing rods 2 are connected to the vertical support rods 1 by steel pipe lock buckles 10.

[0021] In some embodiments, the vertical support rods 1 and the horizontal fixing rods 2 are made of stainless steel.

[0022] Planting floats 3 are arranged between each adjacent row of supporting vertical poles 1. The outer periphery of the planting floats 3 is connected to the adjacent horizontal fixed poles 2 through nylon ropes 6. The planting floats 3 are spliced ​​together by multiple float units, and submerged plants 4 grow on the planting floats 3.

[0023] In some embodiments, the submerged plant 4 is Vallisneria or Hydrilla verticillata.

[0024] By adjusting the position of the steel pipe lock 10 on the supporting vertical rod 1, the distance between the submerged plant 4 and the water surface can be adjusted to ensure that the submerged plant 4 has sufficient sunlight. At the same time, the planting float 3 can block the light in the lower layer and prevent algae from breeding.

[0025] In order to prevent the planting float 3 from floating up and deforming under its own buoyancy, multiple longitudinal pressure rods 9 are arranged in parallel on the upper surface of the planting float 3, and the transverse pressure rods 8 are respectively connected to each longitudinal pressure rod 9. As a preferred solution, the transverse pressure rods 8 are connected to the longitudinal pressure rods 9 through steel pipe locks 10. There are multiple transverse pressure rods 8, the longitudinal pressure rods 9 and the transverse pressure rods 8 are perpendicular, and the transverse pressure rods 8 are parallel to the transverse fixing rods 2. The two ends of the longitudinal pressure rods 9 are respectively connected to the corresponding support vertical rods 1 of the adjacent rows through steel pipe locks 10.

[0026] In this embodiment, the length of the two ends of the longitudinal pressing rod 9 extending outward from the outer side of the upper surface of the planting floating plate 3 is 50 cm.

[0027] To prevent aquatic animals from grazing on the submerged plants 4, the planting float 3 is placed in a fish trap 5. The fish trap 5 is open at the top and sealed at the bottom. Nylon ropes 6 are installed at the top and bottom of the fish trap 5 to prevent aquatic animals from approaching the submerged plants 4. The nylon ropes 6 at the bottom of the fish trap 5 are connected to the support vertical rods 1 via fixing straps 7. The bottom of the fish trap 5 is ensured to be at least 50 cm below the planting float 3, ensuring space for the roots of the submerged plants 4 to grow. In this embodiment, the bottom of the fish trap 5 is 60 cm below the planting float 3.

[0028] The nylon rope 6 arranged on the upper part of the fish blocking net 5 is connected to the supporting vertical rod 1 through a fixing belt 7. The top position of the fish blocking net 5 is higher than the design flood level to prevent fish from entering the fish blocking net 5 during the flood period.

[0029] In some embodiments, the fish blocking net 5 is made of dense polyethylene net, the mesh size is ≥1mm, the mesh size is 10mm×10mm, and the nylon rope 6 size is 6mm in diameter.

[0030] During installation, follow these steps:

[0031] 1. Measure the height from the flood level to the lake bottom, select stainless steel pipes as support rods 1. The length of the support rods 1 should be twice the height from the flood level to the lake bottom. Insert the support rods 1 into the lake bottom and fix them. The support rods 1 should be arranged in multiple rows.

[0032] 2. Fix the horizontal fixing rod 2 to the supporting vertical rod 1 through the steel pipe lock 10;

[0033] 3. Place the planting float 3 in the pocket-shaped fish intercepting net 5, arrange the planting float 3 between each adjacent row of supporting vertical rods 1, and use nylon rope 6 to fix the planting float 3 to the adjacent horizontal fixing rods 2;

[0034] 4. Arrange multiple longitudinal pressing rods 9 on the upper surface of the planting float 3. The longitudinal pressing rods 9 are perpendicular to the transverse fixing rods 2 in the horizontal plane. Fix the transverse pressing rods 8 and each longitudinal pressing rod 9. Set multiple transverse pressing rods 8, and connect the ends of the longitudinal pressing rods 9 to the adjacent rows of support vertical rods 1 through steel pipe lock buckles 10.

[0035] 5. Connect the nylon ropes 6 at the upper and lower parts of the fish blocking net 5 to the supporting vertical poles 1 through fixing belts 7 respectively.
