Description

Technical Field

[0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a settleable suspended seaweed ecological restoration device. Background Art

[0002] Seaweed plays a key role in aquatic ecosystems. Some seaweed can survive in freshwater bodies. It can absorb nutrients, fix carbon dioxide, and provide habitats for marine or lake organisms. However, with the development of coastal economies, problems such as eutrophication of seawater and lake water bodies have occurred frequently, which will lead to the destruction of seaweed habitats and a reduction in the number of seaweed, thereby affecting the ecological balance of oceans and lakes. Traditional restoration methods have certain limitations. For example, the artificial cultivation of seaweed is inefficient and greatly affected by environmental factors. Against this background, seaweed ecological restoration devices have emerged. This device can simulate the natural growth environment of seaweed, improve the efficiency of seaweed restoration, and can flexibly respond to different marine and lake environmental conditions to create favorable conditions for seaweed growth, thereby effectively improving the marine ecological environment.

[0003] Application No. WO2012174983A1 discloses a suspended aquatic plant bed device for underwater ecological restoration. The device comprises a main structure, a buoyancy device mounted on the main structure, a meshed aquatic plant planting platform positioned between the main structures, and a securing device. This invention enables suspended aquatic plant planting in deeper water bodies, thereby improving the effectiveness of aquatic ecological restoration projects. However, this patent still has room for improvement.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0005] To address the challenges of existing technologies, the present invention provides a settleable, suspended seaweed ecological restoration device for freshwater ecological restoration. This device utilizes seaweed to absorb and assimilate large amounts of nutrients such as nitrogen and phosphorus in the water, effectively addressing the problem of rapid eutrophication.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A sinkable, suspended seaweed ecological restoration device comprises a first roller and a second roller arranged opposite each other, and an elastic rope wrapped around the first and second rollers. The elastic rope is provided with a float, and the elastic rope comprises two opposing auxiliary ropes, each provided with a limit plate. Both rollers are provided with a roller frame, and the first and second rollers are arranged above the water surface. The roller frames can be buried on the shore or fixedly mounted on a vessel. The float utilizes buoyancy to increase the seaweed-carrying capacity of the upper portion of the elastic rope. The limit plate ensures that the two rope portions of the elastic rope are always kept at a certain distance from each other, preventing the elastic rope from separating from the first and second rollers.

[0008] According to one embodiment of the present invention, a bridging body is provided under the elastic rope body. The bridging body is a square cylinder with a curved surface at the top. The side wall of the square cylinder is provided with a through hole, and the through hole is provided on the curved surface of the square cylinder. The bridging body is relatively arranged at the lower side of the first roller and the second roller, and the bridging body is located between the first roller and the second roller. The first roller and the second roller are arranged above the horizontal plane. The bridging body is fixedly buried on the seabed at a distance close to the first roller and the second roller, and the upper curved surface of the bridging body is partially exposed on the seabed. In waters with fast currents, since the elastic rope body is arranged inside the through hole, the displacement of the elastic rope body will be limited, preventing the elastic rope body 103 from falling off the bridging body. A net body is provided under the elastic rope body, and a counterweight ball is fixed at the end of the net body.

[0009] In oceans and freshwater lakes, algae often grow abundantly. These algae often reside at varying depths within the water, depending on the environment, water resources, or species. Most algae are typically long and easily entangled in the rope. During installation, the elastic rope is wrapped around first and second rollers, which divide it into two sections: the upper section, closer to the water surface, and the lower section, farther away, naturally submerged. As the algae and water flow, they entangle the upper and lower sections of the rope. Because the types and quantities of algae at different depths vary, a weight difference between the two sections arises when the seaweed entangles. The rope slides along the first and second rollers until the weight balances. Because the movement of seaweed and the flow of water are continuous, the upper and lower parts of the elastic rope are in a state of dynamic equilibrium. To maintain this dynamic equilibrium, the rope continuously moves up and down, moving the seaweed from deeper layers with more algae to those with less. Furthermore, due to the rope's inherent elasticity, entangled algae may slip or break and fall off the rope during movement. Once detached, the increased weight of the entangled algae causes it to settle at different depths, redistributing the algae in the water to different depths and locations. This repeated process ensures that algae are distributed throughout the water at different depths, achieving the desired water purification effect.

[0010] Eutrophic waters often contain large amounts of nitrogen, phosphorus, and other substances deposited at the bottom. These substances are often mixed with bottom mud and sediment. Algae, which float in the water, are unable to purify these substances. The net is fixed to a lower elastic rope with weighted balls at its ends. Under the impact of the flowing water, the net drives the weighted balls back and forth, which not only covers the net but also increases the net's surface area. This creates countercurrents between the swaying net and the weighted balls and the bottom water, which in turn lifts the bottom mud and sediment, allowing nitrogen, phosphorus, and other substances to float to the surface and be absorbed by the algae. At the same time, the algae-covered net creates countercurrents with the bottom water, increasing the continuous impact of the water on the net and removing less active or dead algae.

[0011] A lap joint is provided for mounting the lower elastic rope body in the through hole on the lap joint, so as to prevent the lower elastic rope body from being worn due to long-term friction caused by the bottom support, and reduce the possibility of the elastic rope body sliding unsmoothly due to friction.

[0012] According to one embodiment of the present invention, a limiting plate array is disposed on an elastic rope. The limiting plates are provided with opposing first through-holes, with second through-holes disposed between the first through-holes. The diameter of the first through-holes is greater than that of the elastic rope. A connecting rope is connected to the second through-holes, which is connected to a floating body. A connecting ring is fixedly provided at the bottom end of the floating body, and the connecting rope is fixedly connected to the connecting ring. The floating body array is disposed above the elastic rope.

[0013] The elastic rope slides violently, so both the first and second rollers are designed with larger diameters on both sides than in the middle. This ensures that the elastic rope remains firmly on the rollers and does not fall off. Furthermore, the elastic rope consists of two opposing ropes connected by a stopper plate. The diameter of the first through-hole is larger than the diameter of the elastic rope, allowing the elastic rope to have free space within the first through-hole. Passing through the two first through-holes in the stopper plate also prevents the two ropes from separating and unevenly applying force, potentially causing the elastic rope to slip off the first and second rollers. During use, the evenly spaced stoppers prevent algae from tangling with the ropes during operation, preventing them from sliding together. A float is attached to the second through-hole via a connecting rope. The degree of sinking of the float allows personnel to determine the distribution of underwater algae. The buoyant pull of the float on the upper portion of the elastic rope allows the upper portion to carry more algae, indirectly increasing the algae removal rate at the upper surface of the water. At the same time, the float on the water surface can serve as a dividing line to divide the water body into two parts. People can observe and detect the water quality on both sides more intuitively based on the float.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The weight difference between the upper and lower sections of the elastic rope, caused by the different loads of seaweed, allows the rope to maintain a dynamic equilibrium. As the rope moves, it moves seaweed from deeper layers with more algae to deeper layers with less. Simultaneously, the added weight of seaweed that breaks off the rope redistributes the algae to different depths and locations. This repeated process ensures that algae are distributed throughout the water at different depths. Furthermore, the design of the net and weighted balls allows nitrogen, phosphorus, and other substances deposited in the mud and sediment at the bottom of the water to float back into the water, where they can be absorbed and purified by the algae.

[0016] The degree to which the float sinks allows personnel to determine the distribution of underwater algae. The pull of the float on the elastic rope allows the upper portion of the rope to carry more algae, indirectly increasing the algae removal rate on the upper surface. The float also serves as a dividing line, allowing personnel to more intuitively observe and monitor the water quality on both sides of the float. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0028] Embodiment one

[0029] Referring to the drawings Figure 1-Figure 7 As shown in the drawings, a sinkable suspended seaweed ecological restoration device includes a first roller 101 and a second roller 102 arranged opposite to each other, and an elastic rope body 103 wound on the first roller 101 and the second roller 102. The elastic rope body 103 is provided with a floating body 10. The elastic rope body 103 is two oppositely arranged rope groups, and the elastic rope body 103 is provided with a limiting plate body 201. Both rollers are provided with a roller frame. The first roller 101 and the second roller 102 are arranged above the water surface. The first roller 101 and the second roller 102 can be buried on the shore or fixedly arranged on a ship. The floating body 10 can use buoyancy to improve the carrying capacity of the upper part of the elastic rope body 103 for seaweed. The limiting plate body 201 keeps the two parts of the elastic rope body 103 at a certain distance, so as to avoid the elastic rope body 103 from being separated from the first roller 101 and the second roller 102.

[0030] The elastic rope body 103 is provided with a lapping body 20. The lapping body 20 is a square column with a curved top end. The side wall of the square column is provided with a through hole. The through hole is arranged on the curved surface of the square column. The lapping body 20 is arranged opposite to the lower side of the first roller 101 and the second roller 102. The lapping body 20 is located between the first roller 101 and the second roller 102. The first roller 101 and the second roller 102 are arranged above the horizontal plane. The lapping body 20 is fixedly buried on the seabed close to the first roller 101 and the second roller 102. The upper curved part of the lapping body 20 protrudes out of the seabed. In an area with rapid water flow, the displacement of the elastic rope body 103 is limited because the elastic rope body 103 is arranged inside the through hole, so as to avoid the elastic rope body 103 from falling off the lapping body 20. The elastic rope body 103 is provided with a net body 301. The net body 301 is provided with a counterweight ball 302 at the end.

[0031] In oceans and freshwater lakes, algae often grow in abundance. Depending on the environment, water resources, or species, these algae often reside at varying depths within the water. Most algae are generally long and easily entangled in the rope. During installation, the elastic rope 103 is mounted around the first and second rollers 101 and 102. These rollers divide the elastic rope 103 into two sections, the upper section closer to the water surface and the lower section farther away, naturally submerged. As the algae and water flow, they entangle the upper and lower sections of the elastic rope 103. Because the types and quantities of algae at different depths vary, a weight difference between the upper and lower sections of the rope 103 occurs when the algae entangles them. The elastic rope 103 slides along the first and second rollers 101 and 102 until the weight balance is achieved. Because the movement of the seaweed and the flow of the water are continuous, the upper and lower portions of the elastic rope 103 are in a state of dynamic equilibrium. In the process of maintaining this dynamic equilibrium, the elastic rope 103 continuously moves up and down, moving the seaweed from a water depth with more algae to a water depth with less algae. Furthermore, during the movement of the elastic rope 103, due to its inherent elasticity, entangled algae may slip or break and fall off the elastic rope 103. After falling off, the increased weight of the entangled algae causes them to settle in different water depths, redistributing the algae in the water to different depths and locations. This repetitive process allows algae to be distributed throughout the water at different depths, thereby achieving the desired water purification effect.

[0032] Eutrophic water bodies often have a large amount of nitrogen, phosphorus and other substances deposited on the bottom of the water. These substances are usually mixed with underwater sludge or sediment. Since algae plants float in the water, they cannot purify nitrogen, phosphorus and other substances at the bottom of the water. The net body 301 is fixed on the lower elastic rope body 103, and a counterweight ball 302 is provided at the end of the net body 301. In this way, under the impact of the flowing water, the net body 301 will drive the counterweight ball 302 to swing back and forth. On the one hand, the net body 301 can also be covered with algae. On the other hand, the net body 301 covered with algae will increase the force-bearing area of ​​the net body 301, so that the swinging net body 301 and the counterweight ball 302 form convection with the underwater water flow, thereby driving the underwater sludge and sediment to float, and then causing the nitrogen, phosphorus and other substances at the bottom of the water to float in the water, and then be purified and absorbed by the algae. At the same time, the net body 301 covered with algae will form convection with the bottom water flow, and the continuous impact force of the water flow on the net body 301 will become greater, which can remove algae with low biological activity or dead algae.

[0033] The overlapping body 20 is provided to install the lower elastic rope body 103 in the through hole on the overlapping body 20, so as to avoid the lower elastic rope body 103 being subjected to friction for a long time due to the bottom support, thereby causing wear on the elastic rope body 103, and reducing the possibility of the elastic rope body 103 sliding unsmoothly due to friction.

[0034] Limiting plates 201 are arranged in an array on elastic rope 103. First through holes 202 are positioned opposite each other on limiting plates 201. Second through holes 203 are positioned between the first through holes. The diameter of first through holes 202 is larger than that of elastic rope 103. Connecting ropes 105 are connected to second through holes 203. Connecting ropes 105 are connected to floating bodies 10. Connecting rings 104 are fixedly mounted at the bottom ends of floating bodies 10. Connecting ropes 105 are fixedly connected to connecting rings 104. Floating bodies 10 are arranged in an array above elastic rope 103.

[0035] The elastic rope 103 slides quite violently, so both the first roller 101 and the second roller 102 are configured with diameters on both sides larger than their center diameter. This ensures that the elastic rope 103 remains on the rollers and does not fall off. Furthermore, the elastic rope 103 is composed of two opposing ropes connected by a stopper plate 201. The diameter of the first through-hole 202 is larger than that of the elastic rope 103, allowing free space for the elastic rope 103 within the first through-hole 202. Passing the two ropes through the two first through-holes 202 in the stopper plate 201 also prevents the elastic rope 103 from slipping off the first and second rollers 101, 102, due to uneven force applied due to the two ropes being separated. During use, the evenly spaced stoppers 201 prevent the ropes from sliding together, as algae can become entangled. Floating body 10 is attached to second through-hole 203 via connecting rope 105. The degree of sinking of floating body 10 allows personnel to determine the distribution of underwater algae. The buoyancy of floating body 100 on upper elastic rope 103 allows it to carry more algae, indirectly increasing the algae removal rate on the upper surface. Furthermore, floating body 10, located on the water surface, serves as a dividing line, dividing the water into two parts. Using floating body 10, personnel can more intuitively observe and monitor the water quality on both sides.

Any person skilled in the art may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present invention, but they should still be regarded as technologies or embodiments that are essentially the same as the present invention.
