Description

Technical Field

[0001] This utility model relates to the field of ecological restoration, specifically a river ecological restoration device for environmental protection. Background Technology

[0002] River ecological restoration technology is an important means of restoring the ecological health of aquatic bodies. Among them, river ecological restoration devices improve water quality and restore the function of aquatic ecosystems in various ways, and are gradually becoming an important tool in modern environmental protection. In existing river ecological restoration devices, ecological floating boards are one of the key components. They mainly provide a suitable growth platform by floating on the water surface, allowing aquatic plants such as duckweed and algae to absorb nutrients (such as nitrogen and phosphorus) and carry out photosynthesis, thereby purifying the water.

[0003] Currently, ecological floating panels are mostly fixed using a combination of bolts and screw holes. This traditional method typically requires drilling holes on both sides of the floating panel and inserting bolts to ensure stability between the panels. However, in practice, connecting each floating panel requires multiple drilling and bolt installations, resulting in a large workload and complex operation, especially when connecting a large number of panels, making the process tedious and time-consuming. Therefore, to address these issues, an environmentally friendly river ecological restoration device is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that traditional ecological floating plates require multiple drilling and bolt installations, which is labor-intensive and complex, especially when connecting a large number of floating plates, the process is tedious and time-consuming, this utility model proposes an environmentally friendly river ecological restoration device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: the river ecological restoration device for environmental protection described in this utility model includes at least one floating island unit, which is formed by connecting multiple ecological floating plates to each other through connectors. The ecological floating board includes a floating body, a planting trough, and a root channel; The planting trough is used to grow aquatic plants, and the root channel allows plant roots to extend into the water; The floating island units are fixed in the river channel by an anchoring system.

[0006] Preferably, the connector includes a connecting frame and a rotating shaft. Each connector includes two connecting frames, which are rotatably connected to each other via the rotating shaft. The connecting frames are rotatably connected to the floating body, allowing the ecological floating boards to rotate relative to each other within a certain angle, so that the floating island unit can adapt to water surface fluctuations and water flow changes.

[0007] Preferably, the connecting frame includes a connecting plate connected to the rotating shaft. A mounting housing is provided on the side of the connecting plate away from the rotating shaft. A locking block is slidably installed at both ends of the mounting housing. A drive plate is slidably installed at both ends of the inner side of the mounting housing. The locking block is fixed to the side wall of the drive plate. The end of the drive plate away from the locking block passes through a through groove opened on the side wall of the mounting housing, and the end is slidably installed in a symmetrical movable groove opened on the connecting plate by a clamping plate. A groove is opened on the side wall of the float, and a slot is opened on the inner wall of the groove to engage with the locking blocks on both sides.

[0008] Preferably, a spring is provided inside the mounting housing and between the two drive plates.

[0009] Preferably, a telescopic sleeve is provided on the inner side of the spring, and the two ends of the telescopic sleeve are respectively connected to the two drive plates on both sides.

[0010] Preferably, the float of the ecological floating board is made of closed-cell foam plastic or recycled plastic, and has an internal cavity to enhance buoyancy.

[0011] Preferably, the planting trough is located on the upper part of the float, and the root channel is a mesh or perforated structure that runs through the float, allowing plant roots to freely extend into the water to absorb nutrients.

[0012] Preferably, the anchoring system includes a fixing sleeve fixed to the buoy, the fixing sleeve being equipped with an anchor chain and an anchor rod, one end of the anchor chain being connected to the fixing sleeve, and the other end being fixed to the riverbank by the anchor rod.

[0013] The advantages of this utility model are: 1. Multiple ecological floating boards are combined to form a floating island unit by setting connectors. The floating island unit is placed in a designated position in the river channel by an anchoring system. At this time, the floating body floats on the water surface, and the planting trough is exposed above the water surface, providing growth space for aquatic plants. The aquatic plants are planted in the planting trough, and their roots extend into the water through root channels, which can fully absorb nutrients in the water, such as nitrogen, phosphorus and other eutrophic substances, thereby achieving the purpose of purifying the water quality.

[0014] 2. When the water surface fluctuates or the water flow changes, the connecting components, including connecting frames and rotating shafts, allow the ecological floating panels to rotate relative to each other within a certain angle. This is because the two connecting frames of each component are rotatably connected via the rotating shaft, and the connecting frames are also rotatably connected to the floating body. When the water flow is stronger on one side, adjacent ecological floating panels will rotate around the rotating shaft at a certain angle to adapt to the change in water flow, ensuring the overall stability of the floating island unit and preventing it from falling apart or being damaged by the impact of the water flow.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0019] Please see Figure 1-5 As shown, an environmental protection river ecological restoration device includes at least one floating island unit, which is formed by connecting multiple ecological floating plates to each other through connectors. The ecological floating board includes a float 1, a planting trough 2, and a root channel 3; The planting trough 2 is used to plant aquatic plants, and the root channel 3 allows plant roots to extend into the water; The floating island units are fixed in the river channel by an anchoring system; During operation, multiple ecological floating boards are combined to form floating island units by setting quick-release connectors, improving assembly and disassembly efficiency. The floating island units are placed in designated locations in the river channel through the anchoring system. At this time, the float 1 floats on the water surface, and the planting trough 2 is exposed above the water surface, providing growth space for aquatic plants. The aquatic plants are planted in the planting trough 2, and their roots extend into the water through the root channels 3, which can fully absorb nutrients in the water, such as nitrogen, phosphorus and other eutrophic substances, thereby achieving the purpose of purifying the water quality.

[0020] The connector includes a connecting frame and a rotating shaft 13. Each connector includes two connecting frames, which are rotatably connected to each other via the rotating shaft 13. The connecting frames are rotatably connected to the float 1, allowing the ecological floating boards to rotate relative to each other within a certain angle so that the floating island unit can adapt to water surface fluctuations and water flow changes. The connecting frame includes a connecting plate 8 connected to the rotating shaft 13. A mounting housing 5 is provided on the side of the connecting plate 8 away from the rotating shaft 13. A locking block 6 is slidably installed at both ends of the mounting housing 5. A drive plate 7 is slidably installed at both ends of the inner side of the mounting housing 5. The locking block 6 is fixed on the side wall of the drive plate 7. The end of the drive plate 7 away from the locking block 6 passes through a through groove 9 opened on the side wall of the mounting housing 5, and the end is slidably installed in a symmetrical movable groove 10 opened on the connecting plate 8 by a clamping plate 14. A groove 4 is opened on the side wall of the float 1. A locking groove 15 is opened on the inner wall of the groove 4 to engage with the locking blocks 6 on both sides. A spring 12 is provided inside the mounting housing 5 and between the two drive plates 7 on both sides; During operation, when the water surface fluctuates or the water flow changes, the connecting components, including connecting frames and rotating shafts 13, allow the ecological floating panels to rotate relative to each other within a certain angle. For example, when the water flow is stronger on one side, adjacent ecological floating panels will rotate around the rotating shaft 13 at a certain angle to adapt to the change in water flow, ensuring the overall stability of the floating island unit and preventing it from falling apart or being damaged by the impact of the water flow. Furthermore, the locking blocks 6 at both ends of the mounting housing 5 play a crucial role in the connection process. When it is necessary to connect two ecological floating boards, the mounting housing 5 is placed near the groove 4 on the side wall of the float 1. By simultaneously pushing the drive plates 7 on both sides inward, the drive plates 7 slide along the through groove 9 inside the mounting housing 5, causing the locking blocks 6 to move into the mounting housing 5. At this time, the locking blocks 6 are compressed. Then, the locking blocks 6 are aligned with the slot 15, the drive blocks are released, and under the rebound action of the spring 12, the drive blocks 6 move outward and are locked into the slot 15 on the inner wall of the groove 4, thus achieving the connection and fixation of the two ecological floating boards. The spring 12 provides a certain elastic force during connection, allowing the locking blocks 6 to be more firmly locked in the slot 15. By adopting the above connection method, the operation is simple, the connection is stable, and the assembly and disassembly between ecological floating boards can be quickly realized, improving disassembly efficiency and facilitating the maintenance and adjustment of the floating island unit.

[0021] The inner side of the spring 12 is provided with a telescopic sleeve 11, and the two ends of the telescopic sleeve 11 are respectively connected to the two drive plates 7 on both sides. When working, the telescopic sleeve 11 provided on the inner side of the spring 12 is connected to the two drive plates 7 on both sides, which plays the role of restricting the extension and retraction direction of the spring 12, ensuring that the spring 12 can only extend and retract along the axial direction, and further improving the stability of the connection.

[0022] The floating body 1 of the ecological floating board is made of closed-cell foam plastic or recycled plastic, with an internal cavity to enhance buoyancy. During operation, the internal cavity structure of the floating body 1, made of closed-cell foam plastic or recycled plastic, effectively enhances the buoyancy of the floating island unit. Closed-cell foam plastic has the characteristics of low density and low water absorption, which allows it to float on the water surface for a long time without easily sinking. Recycled plastic is made by recycling waste plastic, which is both environmentally friendly and economical. The internal cavity design further reduces the weight of the floating body 1 while increasing the volume of water displaced, thereby improving buoyancy and ensuring that the floating island unit can float stably under various water level conditions, providing a good growth environment for aquatic plants.

[0023] The planting trough 2 is located above the float 1. The planting trough 2 is filled with lightweight planting soil (such as coconut coir) to fix the plants and provide a growth substrate. The root channel 3 is a mesh or perforated structure that runs through the float 1, allowing plant roots to extend freely into the water to absorb nutrients. During operation, the planting trough 2 is positioned above the float 1. This position design allows aquatic plants to receive sufficient sunlight for photosynthesis, promoting plant growth. The root channel 3, designed as a mesh or perforated structure that runs through the float 1, provides ample space for plant roots to grow, allowing them to extend freely into the water and directly absorb nutrients such as nitrogen and phosphorus. This effectively reduces the concentration of nutrients in the water, inhibits excessive algae growth, and thus achieves the purpose of purifying water quality and improving the aquatic environment. Example 2

[0024] Please see Figure 5 As shown in the comparative embodiment one, as another implementation of this utility model, the anchoring system includes a fixing sleeve 16 fixed to the float 1. The fixing sleeve 16 is equipped with an anchor chain and an anchor rod. One end of the anchor chain is connected to the fixing sleeve 16, and the other end is fixed to the riverbank by the anchor rod. In operation, when it is necessary to fix the floating island unit in the river channel, the fixing sleeve 16 is first firmly installed on the float 1 to ensure its stability. Then, one end of the anchor chain is reliably connected to the fixing sleeve 16, and an appropriate length of anchor chain is selected according to the width of the river channel and the water flow conditions. Then, the end of the anchor chain away from the float 1 is fixed to the riverbank by the anchor rod. By adjusting the length and tension of the anchor chain, the floating island unit can be stably positioned in the designated position in the river channel, so that it will not drift excessively due to the impact of water flow, and can adapt to water level changes within a certain range, providing a reliable guarantee for the growth of aquatic plants and the ecological restoration of the river channel.
