Description

Technical Field

[0001] The present invention relates to the field of water ecology technology, and in particular to a water ecology restoration device and a restoration method thereof. Background Art

[0002] Water ecological restoration involves restoring and repairing degraded or damaged aquatic ecosystems through a series of measures, essentially returning them to their original state or exceeding it, and maintaining their long-term stability. Among these measures, eutrophication is one of the major environmental issues facing humanity. Eutrophication is primarily caused by the release of elements such as nitrogen, phosphorus, and potassium into slow-flowing surface waters with long renewal cycles, which in turn leads to the rapid growth and reproduction of aquatic organisms such as algae. This causes the production of organic matter to far exceed its consumption, leading to its accumulation in the water and disrupting the balance of the aquatic ecosystem.

[0003] A key step in water ecological restoration is the cultivation of aquatic plants. The survival of aquatic plants decomposes elements such as nitrogen and phosphorus in the water. Practice has shown that water bodies with lush aquatic plants tend to have better water quality and are crystal clear. However, the current process of river water ecological restoration requires manual planting of cultivated aquatic plants one by one in the mud at the bottom of the river, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a water ecological restoration device to facilitate the cultivation of aquatic plants. Summary of the Invention

DETAILED DESCRIPTION

[0027] It should be noted that, unless there is a conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other. The embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] The present invention provides a water ecological restoration device, comprising a plurality of planting boxes 1 distributed in a grid, wherein a through hole is opened at the bottom end of the planting box 1, and a mesh plate 2 with a hole is fixedly installed in the through hole; a support column 3 is detachably installed at the bottom of the planting box 1, and a counterweight block 4 is detachably installed at the bottom end of the support column 3, and the counterweight block 4 is a conical structure; restoration aquatic plants are planted in the planting box 1, and the roots of the restoration aquatic plants extend out of the planting box 1 through the mesh plate 2 with a hole.

[0029] The present invention plants repair water grass in a planting box 1, and then places the repair device with the planting box 1 as a whole at the bottom of the river that needs to be managed, so as to plant multiple repair water grasses at one time, effectively reducing the labor intensity of the staff; under the action of the counterweight block 4, the support column 3 can partially enter the mud at the bottom of the river, which helps to maintain the stability of the repair device, and utilizes the repair water grass to decompose nitrogen, phosphorus and other elements in the water body, thereby realizing the repair of the river water ecology. The setting of the perforated mesh plate 2, on the one hand, in the early stage of planting the repair water grass, allows the eutrophic water in the river to enter the planting box 1 and be absorbed and purified by the repair water grass; on the other hand, in the later stage of planting the repair water grass, it is convenient for the roots of the repair water grass to extend out of the planting box 1 through the perforated mesh plate 2, slowing down the water flow rate, thereby improving the repair effect on the river water ecology.

[0030] Furthermore, in order to facilitate the grid-distributed planting boxes 1 to maintain structural stability, so that the area where the repair device is located can form a slow-flow area, so as to improve the repair effect of aquatic plants on eutrophic water bodies, the planting boxes 1 are made into a square structure, and a connecting piece is provided above the planting boxes 1, and the planting boxes 1 adjacent to the four corners are connected and fixed by the connecting piece; the connecting piece includes a connecting plate 5, and the four corners of the bottom end of the connecting plate 5 are fixedly connected to the limiting columns 6, and the four limiting columns 6 are distributed in the four planting boxes 1, and the connecting plate 5 is threaded with screws, and the connecting plate 5 is fixed with the planting box 1 by screws.

[0031] Furthermore, in order to prevent the early repaired aquatic plants from escaping from the planting box 1 and affecting the survival rate of the repaired aquatic plants, a water grass cover plate 7 is provided in the planting box 1. The water grass cover plate 7 is provided below the connecting piece and cooperates with the connecting piece to limit the position; the water grass cover plate 7 includes two plates of the same shape, and a semicircular opening is provided in the middle of the opposite sides of the two plates. The two semicircular openings constitute planting holes. Connecting rods 8 are fixedly connected at both ends of one side of any plate close to the semicircular opening, and connecting holes are provided at both ends of the other plate close to the semicircular opening, and the connecting rods 8 are adapted to the connecting holes.

[0032] By setting the water grass cover 7, on the one hand, the position of the repaired water grass can be fixed by using the water grass cover 7, reducing the possibility of the repaired water grass escaping from the planting box 1, thereby improving the survival rate of the repaired water grass. On the other hand, the repaired water grass can grow vertically under the restriction of the planting hole, reducing the possibility of its horizontal growth and reducing the possibility of the repaired water grass overlapping.

[0033] Furthermore, the support column 3 is a hollow structure, and a storage box 9 is provided at the bottom end of the support column 3. The bottom end of the storage box 9 is an open structure, and the counterweight 4 can be removably installed at the bottom of the storage box 9; a plurality of water inlets 10 and a plurality of water outlets 11 are provided on the side wall of the support column 3 in a vertical direction, and the water inlet 10 and the water outlet 11 are symmetrically arranged; a plurality of guide tubes 12 are fixedly connected to the inner wall of the support column 3, and the plurality of guide tubes 12 are spirally arranged downward, and the guide tubes 12 are arranged one by one corresponding to the water inlet 10.

[0034] The water inlet 10 faces the upstream of the river. Through the setting of the diversion pipe 12, water enters through the water inlet 10 and is diverted through the diversion pipe 12. At the flow rate of the water body itself, the water is more likely to form a vortex in the support column 3, which helps impurities such as particulate matter carried in the water body to gather in the storage box 9, which helps to repair the water ecology of the river.

[0035] Furthermore, the top of the counterweight 4 is fixedly connected to a connecting column 13, and the top of the connecting column 13 is fixedly connected to an arc-shaped blocking plate 14. The arc-shaped blocking plate 14 is arranged in the storage box 9, and a gap is provided between the arc-shaped blocking plate 14 and the inner wall of the storage box 9.

[0036] By providing the arc-shaped blocking plate 14 , the impurities gathered at the bottom of the storage box 9 can be intercepted by the arc-shaped blocking plate 14 , thereby reducing the escape of impurities entering the support column 3 , thereby making the water in the river clearer.

[0037] Furthermore, the bottom corners of the planting box 1 are fixedly connected with mounting columns, and the four adjacent mounting columns on the planting boxes 1 at the four adjacent corners form a cylindrical structure, and the cylindrical structure is inserted into the top of the support column 3; the mounting column includes a connecting tube 15 and a wood 16 fixedly installed in the connecting tube 15, the wood 16 is in contact with the inner wall of the support column 3, and the length ratio of the wood 16 to the connecting tube 15 is not less than 1:1.

[0038] By inserting the four mounting posts forming the cylindrical structure into the top of the support posts 3, the planting box 1 can be fixed again using the support posts 3, and the wood 16 will swell after being soaked in water, thereby improving the connection strength between the mounting posts and the support posts 3.

[0039] Furthermore, an interception net is provided between two adjacent support columns 3, and the interception net is provided perpendicular to the direction of water flow. By providing the interception net, particulate impurities such as organic matter in the water body can be intercepted. On the one hand, it can promote the aggregation and reproduction of microorganisms in the water body, accelerate the decomposition of organic matter in the water body, and on the other hand, it helps to repair the rapid growth of aquatic plants, thereby forming a virtuous cycle. Moreover, the provision of the interception net can slow down the flow of the water body. Even if the mesh of the interception net is clogged with particulate impurities, it can still guide the water body, thereby increasing the flow rate of the water body when passing through the support column 3, thereby making the swirl effect in the support column 3 more obvious, thereby improving the aggregation effect of particulate impurities in the water body in the storage box 9.

[0040] A method for water ecological restoration specifically comprises the following steps:

[0041] S1. Assembly of the repair device: First, use the mounting columns to install several planting boxes 1 on the support columns 3, and assemble the planting boxes 1 into a grid structure. Then, plant the repaired aquatic plants in the planting boxes 1, and use the aquatic plant cover 7 to fix the planted repaired aquatic plants. Finally, use the connecting piece to connect and fix the planting boxes 1, and at the same time, use the connecting piece to fix the aquatic plant cover 7.

[0042] S2. Hoist the restoration device planted with restoration aquatic plants into the water body to be restored, and control the distance between the restoration devices along the direction of water flow to be between 15m and 20m;

[0043] S3. Spray flocculants into the water upstream of the restoration device. After dissolving in water, the flocculants can cause the fine particles and natural colloids in the water to condense into large flocs, which then settle and are intercepted and collected by the restoration device. The intercepted and collected flocs can provide a material basis for the reproduction of microorganisms and provide sufficient nutrients for the growth of restored aquatic plants, thereby promoting the growth and survival of the restored aquatic plants and the growth of the roots of the restored aquatic plants. The roots of the restored aquatic plants can further slow down the flow rate of the water body, improve the interception effect of large flocs in the water body, form a virtuous cycle, and achieve the effect of purifying water.

[0044] S4. Regularly clean the storage box 9 and the interception net in the repair device to ensure the interception effect.

[0045] The water ecological restoration device and restoration method provided by the present invention can filter flocs in the water body and use the restoration water plants to absorb nitrogen, phosphorus and other substances in the water, thereby improving the restoration efficiency of the water body; multiple planting boxes 1 can be connected into a whole through the connecting parts and the support column 3, so that the overall structure of the restoration device is more stable; when planting the restoration water plants, they are directly planted in the planting boxes 1 on the shore, and then the whole is hoisted into the water body to be repaired, so that multiple restoration water plants can be planted at one time, effectively reducing the labor intensity of the staff.

[0046] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
