Description

Technical Field

[0001] This utility model relates to the field of river protection net technology, and in particular to a water conservancy river ecological management and protection net. Background Technology

[0002] In the fields of water conservancy engineering and river ecological management, protective nets are a common facility widely used for isolating specific water areas, blocking floating objects, stabilizing riverbanks, and guiding water flow. Traditional river protective nets typically employ a simple structure of posts and metal mesh panels, installed by directly driving or casting the posts into the riverbank or riverbed.

[0003] However, in practical applications, significant shortcomings of existing technologies have been identified. First, their fixing methods are relatively simple, relying primarily on the insertion depth of the columns or concrete foundations for stability. Under long-term water erosion, especially the impact of high-speed floodwaters, the riverbed soil around the base of the columns is easily eroded, leading to column loosening, tilting, or even complete collapse, rendering the protective function ineffective and posing safety hazards. Second, traditional protective net structures have limited functionality, primarily focusing on physical isolation and blocking, lacking ecological considerations. The rigid steel structure or concrete foundation disrupts the natural continuity of the riverbed, hindering the ecological exchange between water and sediment, and failing to meet the requirements of ecological bank protection and promoting water self-purification in modern river management. Therefore, a new type of ecological river management protective net is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a water conservancy river ecological management and protection network to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a water conservancy river ecological management and protection net, including columns, a main frame, and hinges. The main frame is fixedly connected between the columns, and a secondary frame is movably connected to the side of each column through hinges. An internal network is fixedly connected to the inner side of the main frame and the sub-frame, and the network port of the internal network is rectangular. The bottom end of the column is fixedly connected to a box; The box body has reserved holes at its four corners, and steel columns are driven into the reserved holes; The bottom end of the steel column is conical, and the bottom end of the steel column is inserted into the riverbed; The box body has several compartments, two of which are filled with a layer of gravel; The other two compartments are fixedly connected to partitions, and the openings of the partitions and the corresponding compartments are filled with a substrate layer, in which aquatic plants are planted.

[0007] Preferably, in any of the above solutions, the column is welded to the main frame, and the column, main frame, and sub-frame are made of stainless steel.

[0008] The core of this water conservancy river ecological management and protection net, which adopts the above technical solution, lies in the design of the bottom of the columns as a flatter box structure with a certain area, i.e., a box. This design does not only involve opening holes at the four corners for piling and fixing, but also involves opening multiple large grids on the entire surface of the box.

[0009] Before installation, operators can fill the grid with gravel, planting soil, and water-resistant plant roots (such as seedlings of calamus and reeds). Then, the entire protective netting is placed in the designated location in the river channel and secured with steel posts through pre-drilled holes at the four corners. Once the enclosure sinks to the riverbed, the gravel and plants inside play multiple roles. The gravel layer increases the friction between the enclosure and the riverbed, stabilizing the riverbed and preventing erosion of the surrounding area. The aquatic plants planted in the substrate layer gradually penetrate the riverbed, forming a tight bond and further enhancing the netting's stability. Simultaneously, the inner netting on the main and secondary frames prevents garbage and other debris from entering specific areas of the river channel, providing some protection and filtration.

[0010] Preferably, in any of the above embodiments, the column is hollow and the bottom end of the column is welded to the box body.

[0011] Preferably, the edge of the inner mesh is riveted to the inner side of the main frame and the sub-frame, according to any of the above schemes.

[0012] The core design of this device is as follows: the layer of crushed stone filling the tank increases the contact area and friction with the riverbed, effectively preventing water flow from eroding the surrounding riverbed and maintaining its stability. Simultaneously, the roots of aquatic plants penetrate deep into the riverbed, further reinforcing its structure and reducing the risk of erosion.

[0013] The insertion of steel pillars into the riverbed and the tight integration of plants within the enclosure with the riverbed make the entire protective netting installation in the river channel more secure. It can withstand greater water flow impact and external forces, making it less prone to being washed away or damaged, thus extending the lifespan of the protective netting. The aquatic plants such as calamus and reeds planted in the substrate layer not only beautify the river environment but also purify the water. These plants can absorb nutrients such as nitrogen and phosphorus from the water, reducing eutrophication and improving the river's ecological environment.

[0014] Preferably, of any of the above solutions, the grid is rectangular, and the partition is made of plastic or stainless steel.

[0015] Preferably, in any of the above embodiments, the partition is connected to the inner wall of the grid by screws, and the substrate layer is specifically planting soil.

[0016] Preferably, in any of the above schemes, the plants in the substrate layer are calamus and reeds.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This ecological protection netting for river channels features an improved base design for the support columns, incorporating a large-area box structure with several openings. The gravel filling these openings increases the contact area and friction with the riverbed, effectively preventing erosion of the surrounding riverbed and maintaining its stability. Simultaneously, the roots of aquatic plants penetrate deep into the riverbed, further reinforcing its structure and reducing the risk of erosion.

[0018] The insertion of steel pillars into the riverbed and the tight integration of plants within the enclosure with the riverbed make the entire protective netting installation in the river channel more secure. It can withstand greater water flow impact and external forces, making it less prone to being washed away or damaged, thus extending the lifespan of the protective netting. The aquatic plants such as calamus and reeds planted in the substrate layer not only beautify the river environment but also purify the water. These plants can absorb nutrients such as nitrogen and phosphorus from the water, reducing eutrophication and improving the river's ecological environment.

[0024] like Figure 1-4 As shown, this water conservancy river ecological management and protection network includes pillars 1, main frames 2, and hinges 3. The main frames 2 are fixedly connected between the pillars 1, and the secondary frames 4 are movably connected to the sides of the pillars 1 through the hinges 3. The inner sides of the main frame 2 and the secondary frame 4 are fixedly connected to the internal network 5, and the network port of the internal network 5 is rectangular; The bottom end of column 1 is fixedly connected to box 6; Pre-drilled holes 7 are provided at the four corners of the box body 6, and steel columns 8 are driven into the pre-drilled holes 7; The bottom of steel column 8 is cone-shaped and is inserted into the riverbed. The box body 6 has several compartments 9, two of which are filled with a layer of gravel 10; The other two compartments 9 are fixedly connected to partitions 11, and the openings of the partitions 11 and the corresponding compartments 9 are filled with a substrate layer 12, in which aquatic plants are planted.

[0025] Example 1: The upright 1 is welded to the main frame 2. The upright 1, main frame 2, and secondary frame 4 are all made of stainless steel. The upright 1 is hollow, and its bottom end is welded to the box body 6. The edge of the inner mesh 5 is riveted to the inner side of the main frame 2 and secondary frame 4. The grid 9 is rectangular, and the partition 11 is made of plastic or stainless steel. The partition 11 is connected to the inner wall of the grid 9 by screws. The substrate layer 12 is specifically planting soil. The plants in the substrate layer 12 are specifically calamus and reeds.

[0026] Example 2: The core of this water conservancy river ecological management and protection net lies in the design of the bottom of the column 1 as a flatter box structure with a certain area, namely box 6. This design is not only for opening holes at the four corners for piling and fixing, but also for opening multiple large grids 9 on the entire surface of box 6.

[0027] Before installation, operators can fill the grid 9 with gravel, planting soil, and water-resistant plant roots (such as seedlings of calamus and reeds). Then, the entire protective netting is placed in the designated location in the river channel and secured using steel posts 8 through the pre-drilled holes 7 at the four corners. Once the box 6 is submerged, the gravel and plants inside play multiple roles. The gravel layer 10 increases the friction between the box 6 and the riverbed, stabilizing the riverbed and preventing erosion of the surrounding area. The aquatic plants planted in the substrate layer 12 gradually penetrate the riverbed, forming a tight bond and further enhancing the stability of the protective netting installation. Simultaneously, the inner netting 5 inside the main frame 2 and secondary frame 4 prevents garbage and other debris from entering specific areas of the river channel, providing some protection and filtration.

[0028] The working principle of this utility model is as follows: Stainless steel is used to construct the uprights 1, main frame 2, and secondary frame 4, ensuring sufficient strength and corrosion resistance. Uprights 1 are designed with a hollow structure for easy installation and reduced overall weight. A suitably sized box 6 is prepared, made of a material with sufficient strength and water resistance. Steel pillars 8 are purchased, and their bottom ends are machined into pointed cones for easy insertion into the riverbed. An inner mesh 5 is prepared, with rectangular openings and riveting prepared at the edges. Simultaneously, gravel, planting soil, and seedlings of calamus and reeds are prepared as filling materials. Uprights 1 are welded to the main frame 2, ensuring a secure connection. The secondary frame 4 is movably connected to the side of uprights 1 using hinges 3, ensuring flexible opening and closing. The edges of the inner mesh 5 are riveted to the inside of the main frame 2 and secondary frame 4, fixing the inner mesh 5 within the frames. The bottom of uprights 1 is welded to the box 6, forming a complete protective netting structure. In the box 6, select two of the several compartments 9 to fill with a layer of crushed stone 10, ensuring even distribution and a moderate filling height. Select the other two compartments 9 and first secure partitions 11 to their inner walls using screws. Partitions 11 can be made of plastic or stainless steel. Then, fill the openings of partitions 11 and the corresponding compartments 9 with planting soil as a substrate layer 12. Plant seedlings of calamus and reeds in the substrate layer 12, watering appropriately after planting to ensure seedling survival. Transport the assembled and filled protective netting to the designated installation location in the river channel. Using piling equipment, drive steel columns 8 into the riverbed through the pre-drilled holes 7 at the four corners of the box 6, ensuring sufficient depth for the box 6 to sink stably to the riverbed. Adjust the position and angle of the protective netting to meet design requirements. After installation, regularly check the stability of the protective netting and inspect the steel columns 8 for loosening; if any loosening is found, reinforce them promptly. Observe the growth of aquatic plants and carry out watering, fertilization and other maintenance work in a timely manner to ensure the healthy growth of plants and to ensure that they continue to play a role in stabilizing the riverbed and improving the strength of the protective net.

[0029] Compared with the prior art, the present invention has the following advantages: This ecological protection net for river channels features an improved base design for the pillar 1, incorporating a box-like structure 6 with a larger surface area. The box 6 has several openings 9, and the gravel layer 10 filling these openings increases the contact area and friction with the riverbed, effectively preventing water erosion of the surrounding riverbed and maintaining its stability. Simultaneously, the roots of aquatic plants penetrate deep into the riverbed, further reinforcing its structure and reducing the risk of erosion.

[0030] The insertion of steel columns 8 into the riverbed and the close integration of plants within the enclosure 6 with the riverbed make the entire protective netting more securely installed in the river channel. This allows it to withstand greater water flow impact and external forces, making it less prone to being washed away or damaged, thus extending the netting's lifespan. The aquatic plants such as calamus and reeds planted in the substrate layer 12 not only beautify the river environment but also purify the water. These plants can absorb nutrients such as nitrogen and phosphorus from the water, reducing eutrophication and improving the river's ecological environment.
