Description

Technical Field

[0001] The utility model relates to the technical field of plant cultivation, in particular to a water purification plant cultivation device that takes into account the protection of the revetment. Background Art

[0002] Water purification plants mainly refer to aquatic plants, which are generally divided into the following categories: emergent plants, floating-leaved plants, submerged plants, floating plants and hygrophytes. The restoration and reconstruction of aquatic plants play an important role in the steady-state transformation of freshwater ecosystems (from turbid water to clear water) and are the main measures for water ecological restoration.

[0003] At present, in the process of surface runoff water ecological restoration, the planting method of aquatic plants is mainly to plant the cultivated mature aquatic plants on the floating island, and use ropes to horizontally fix the floating island on the revetment of the runoff, so that the floating island is perpendicular to the runoff revetment, and the aquatic plants planted on the floating island form a purification section perpendicular to the water flow direction.

[0004] However, the above planting method still has the following problems: during the long-term erosion by water flow, since the floating island is perpendicular to the runoff revetment, the flow velocity of the surface water body in the middle part of the floating island will be greatly reduced or even in a static state, which will exacerbate the enrichment of elements such as nitrogen and phosphorus in the surface water body in the middle part of the floating island, causing the rapid reproduction of algae and other plankton in the surface water body, forming the "water bloom" phenomenon. This will not only prevent light from entering the water body, but also lead to a decrease in dissolved oxygen in the water body, thus affecting the photosynthesis of aquatic plants and destroying the balance of the water ecological system. The flow velocity of the surface water flow near the two ends of the floating island close to the revetment will increase, which will exacerbate the erosion of the revetment by the water flow and cause more serious soil erosion. Therefore, it is urgent to develop a water purification plant cultivation device to improve the defects existing in the above water plant planting method. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a water purification plant cultivation device that takes into account the protection of the revetment aiming at the deficiencies of the above prior art. It can control the flow velocity of surface runoff, prevent the enrichment of elements such as nitrogen and phosphorus in the surface water body of the runoff, avoid the occurrence of the water bloom phenomenon, ensure the balance of the water ecological system, and at the same time can effectively slow down the erosion of the surface soil of the revetment by the water flow, thereby preventing the water flow from exacerbating the soil erosion at the revetment.

[0006] The technical solution adopted by the present utility model is as follows: A water purification plant planting device that takes into account the protection of the revetment, including a telescopic frame and a fixing column detachably arranged on the telescopic frame. A plurality of extension rods are installed on one side of the telescopic frame away from the fixing column. A planting basket with a porous structure is connected to each extension rod in a lifting manner. The planting basket is used for planting and cultivating water purification plants. A protective cloth for protecting the revetment is provided at the bottom of the telescopic frame. A support rod for tightly pressing the surface of the protective cloth is installed at the end of the telescopic frame close to the extension rod. A stretching member is provided between the fixing column and the extension rod.

[0007] Preferably, a plurality of fixing columns are provided, and fixing strips are detachably connected between each of the fixing columns.

[0008] Preferably, the bottom of each fixing column is a conical structure. A striking part is provided at the top of each fixing column, and an anti-slip layer is provided on the surface of each fixing column.

[0021] To make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figure 1 and Figure 2 , an embodiment of the present utility model provides a water purification plant planting device that takes into account the protection of the revetment, including a telescopic frame 1 and a fixed column 2 detachably arranged on the telescopic frame 1. A plurality of extension rods 3 are installed on one side of the telescopic frame 1 away from the fixed column 2. A porous planting basket 4 is connected to each extension rod 3 in a lifting manner. The planting basket 4 is used for planting and cultivating water purification plants. A protective cloth 5 for protecting the revetment is arranged at the bottom of the telescopic frame 1. A support rod 6 for tightly pressing the surface of the protective cloth 5 is installed at the end of the telescopic frame 1 close to the extension rod 3. A tensile member 7 is arranged between the fixed column 2 and the extension rod 3.

[0023] In some embodiments, the length of the extension rod 3 and the unfolded width of the telescopic frame 1 can be telescopically adjusted.

[0024] In some embodiments, refer to Figure 1 , the planting basket 4 is set to be porous, which is convenient for the growth of the roots of water purification plants and the purification of runoff water bodies.

[0025] In some embodiments, the tensile member 7 is detachably connected between the fixed column 2 and the extension rod 3.

[0026] In some embodiments, refer to Figure 3, a telescopic frame 1 is provided with a plurality of mounting rings 101 facilitating the installation of fixing columns 2 and a limiting rod 102 for mounting and fixing a protective cloth 5.

[0027] In some embodiments, a single plant planting device can serve as a water purification unit for surface runoff. According to the distance between the revetments on both sides of the surface runoff, an appropriate number of water purification units are arranged on both sides of the revetments of the surface runoff, so that a purification section obliquely intersecting the water flow direction can be formed in the runoff.

[0028] In some embodiments, referring to Figure 1 and Figure 2 , a plurality of fixing columns 2 can be provided, and fixing strips 201 are detachably connected between each fixing column 2. In this way, the mutually independent fixing columns 2 can be connected into a whole, ensuring the stability of the telescopic frame 1 on the bank of the surface runoff.

[0029] In some embodiments, referring to Figure 1 , the bottom of each fixing column 2 is a conical structure, a striking part 202 is provided at the top of each fixing column 2, and an anti-slip layer 203 is provided on the surface of each fixing column 2. The conical structure can reduce the resistance of the fixing column 2 when inserted into the soil at the bank slope of the surface runoff. Through the striking part 202 at the top of the fixing column 2, it is convenient to drive the fixing column 2 into the soil of the bank slope of the surface runoff, and the anti-slip layer 203 is conducive to the later disassembly and recycling of the fixing column 2.

[0030] In some embodiments, referring to Figure 4 , the protective cloth 5 includes a matrix layer 501, a nutrient layer 502 and a filling layer 503. Plant seeds for solidifying the runoff revetment are placed in the filling layer 503. The matrix layer 501 provides conditions for the plant seeds to take root on the protective cloth 5, the nutrient layer 502 can provide the nutrients required for the germination and subsequent growth of the plant seeds, and the filling layer 503 can effectively prevent the plant seeds from being washed away by the water flow. Through the protective cloth 5, the erosion of the surface soil of the revetment by the water flow can be effectively reduced, and the surface soil at the revetment can be protected and fixed by the plant seeds.

[0031] In some embodiments, referring to Figure 3 , one end of the support rod 6 in contact with the surface of the protective cloth 5 is provided with a pressing block 601, and a tooth nail 602 is provided on the pressing block 601. Through the cooperation of the pressing block 601 and the tooth nail 602 on the support rod 6, it is convenient for the whole support rod 6 to tightly press the protective cloth 5 at the revetment, so that the protective cloth 5 at the revetment always closely adheres to the surface soil at the revetment, which is conducive to the germinated plant seeds in the protective cloth 5 taking root in the surface soil of the revetment.

[0032] In some embodiments, the stretching member 7 is a connecting rope made of a flexible material or a connecting rod made of a rigid material. The stretching member 7 provides the required supporting force for the extension rod 3, ensuring that the planting basket 4 connected to the extension rod 3 can be stably located at the surface water body of the surface runoff, enabling the aquatic plants in the planting basket 4 to grow and develop normally, and ensuring the normal progress of the water ecological restoration work of the surface runoff by the water purification plants.

[0033] When the present utility model is specifically used:

[0034] According to the distance between the revetments on both sides of the surface runoff, an appropriate number of telescopic frames 1 are installed on both sides of the revetments of the surface runoff. At the same time, the protective cloth 5 is laid on the shore of the surface runoff, so that the surface of the protective cloth 5 is closely attached to the surface soil of the revetment and the bank slope of the surface runoff. The telescopic frame 1 is unfolded to an appropriate width, and the limiting rod 102 on the telescopic frame 1 presses and fixes the protective cloth 5 at the bank slope part of the surface runoff, so that the protective cloth 5 is closely attached to the bank slope part of the surface runoff. The protective cloth 5 can reduce the scouring of the water flow on the revetment, and the plant seeds in the protective cloth 5 can further protect and fix the surface soil at the revetment and the bank slope, effectively reducing the soil erosion at the revetment.

[0035] Insert the fixing column 2 into the mounting ring 101 of the telescopic frame 1 to completely fix the telescopic frame 1 at the bank slope of the surface runoff, and form an integral body of the independent fixing columns 2 through the fixing strip 201. It should be noted that there is a safety distance between the position where the fixing column 2 is inserted into the soil of the bank slope of the surface runoff and the edge position of the revetment, preventing the soil at the edge of the revetment from collapsing and avoiding aggravating the soil erosion at the revetment of the surface runoff.

[0036] After the fixing column 2 is installed, adjust the position of the supporting rod 6 at the end of the telescopic frame 1, and tightly press the surface of the protective cloth 5 at the revetment part through the pressing block 601 and the tooth nail 602 on the supporting rod 6, so that the protective cloth 5 is always closely attached to the surface soil of the revetment, thereby facilitating the plant seeds in the protective cloth 5 to take root in the surface soil of the revetment. Adjust the length of the extension rod 3 to adjust the placement position of the planting basket 4 arranged thereon for lifting and lowering, and adjust the height of the planting basket 4 relative to the runoff liquid surface according to the height of the bank slope of the surface runoff and the runoff liquid surface, ensuring the normal growth and development of the water purification plants in the planting basket 4, thereby forming a purification section in the runoff water body that is obliquely intersecting with the water flow direction and for the water ecological restoration of the surface runoff. The oblique intersection of the purification section and the water flow direction of the runoff can effectively control the water flow velocity of the runoff water body, facilitating the water ecological restoration of the surface runoff by the water purification plants, and at the same time not blocking the water purification channel and avoiding the occurrence of the "water bloom" phenomenon caused by the enrichment of elements such as nitrogen and phosphorus, ensuring the balance of the water ecological system in the surface runoff.
