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 efficiency of artificially cultivated seaweed is low and it is 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. WOCN12076463 discloses a suspended waterweed bed device for underwater ecological restoration, comprising a main structure, a buoyancy device arranged on the main structure, a waterweed planting mesh platform arranged between the main structures, and a fixing device. The invention can complete the suspended planting of waterweed in deeper water bodies, thereby improving the effect of water body ecological restoration projects. This patent still has room for improvement.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a settleable suspended seaweed ecological restoration device for freshwater ecological restoration. The device can utilize seaweed to absorb and assimilate a large amount of nutrients such as nitrogen and phosphorus in the water, effectively solving the problem of rapid eutrophication of water bodies.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: A sinkable suspended seaweed ecological restoration device comprises a first roller and a second roller arranged opposite to each other, and an elastic rope body wound around the first roller and the second roller, a floating body is arranged on the elastic rope body, the elastic rope body is composed of two auxiliary rope bodies arranged opposite to each other, and a limiting plate body is arranged on the elastic rope body. Both rollers are provided with a roller frame, the first roller and the second roller are arranged above the water surface, the roller frames of the first roller and the second roller can be buried on the shore or fixed on a ship, the floating body can use buoyancy to increase the carrying capacity of the upper part of the elastic rope body for seaweed, and the limiting plate body can be used to keep the two parts of the rope body constituting the elastic rope body at a certain distance at all times to prevent the elastic rope body from detaching from the first roller and the second roller.

[0007] According to one embodiment of the present invention, a lap joint is provided under the elastic rope body, and the lap joint is a square cylinder with a curved surface at the top, and a through hole is provided on the side wall of the square cylinder, and the through hole is provided on the curved surface of the square cylinder. The lap joint is relatively arranged at the lower side of the first roller and the second roller, and the lap joint is located between the first roller and the second roller. The first roller and the second roller are arranged above the horizontal plane. The lap joint is fixedly buried on the seabed close to the first roller and the second roller, and the upper curved surface of the lap joint partially leaks out on the seabed. In waters with rapid water flow, since the elastic rope body is arranged inside the through hole, the displacement of the elastic rope body will be limited, and the elastic rope body 103 will be prevented from falling off the lap joint. A net body is provided under the elastic rope body, and a counterweight ball is fixedly provided at the end of the net body.

[0008] There are often many seaweeds in the seawater or freshwater environment of the lake. These seaweeds are often located at different depths in the water resources according to the living environment, water resources or seaweed species. Most seaweeds are generally long in shape and easy to be entangled on the rope. When the elastic rope is installed, since the elastic rope is installed around the first roller and the second roller, the two rollers divide the elastic rope into two parts, the upper part is closer to the water surface, and the lower part is farther from the water surface and naturally sinks in the water. During the flow of seaweed and water, the seaweed will be entangled on the upper and lower parts of the elastic rope. Since the types and quantities of seaweed at different depths are different, when the seaweed is entangled on the upper and lower parts of the elastic rope, there will be a weight difference between the upper and lower parts of the rope, and the elastic rope will slide along the first roller and the second roller until the weight is balanced. And because the movement of seaweed and the flow of water are continuous, the upper and lower parts of the elastic rope will be in a state of dynamic balance. In the process of maintaining this dynamic balance, the elastic rope will move up and down continuously, and will move the seaweed from the water depth layer with more algae to the water depth layer with less algae. At the same time, in the process of the movement of the elastic rope, since the elastic rope itself has a certain elasticity, the entangled algae may slide or break and fall off the elastic rope. After falling off, due to the increase in the deadweight of the entangled algae, it is placed in different water depths, and the algae in the water can be redistributed to different depths and different positions. This can be repeated, so that the algae can be distributed in different water depths in the water body, thereby achieving the effect of purifying the water body.

[0009] 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 bottom mud or sediment. Since algae plants float in the water, they cannot purify nitrogen, phosphorus and other substances located at the bottom of the water. The net body is fixed on the lower elastic rope body, and a counterweight ball is set at the end of the net body. In this way, under the impact of the water flow, the net body will drive the counterweight ball to swing back and forth. On the one hand, the net body can also be covered with algae. On the other hand, the net body covered with algae will increase the force-bearing area of ​​the net body, so that the swinging net body and the counterweight ball will form convection with the bottom water flow, thereby driving the bottom mud and sediment to float, and then making the nitrogen, phosphorus and other substances located at the bottom of the water float in the water, and then be purified and absorbed by the algae. At the same time, the net body covered with algae will form convection with the bottom water flow, and the continuous impact of the water flow on the net body will increase, which can remove algae with low biological activity or dead algae.

[0010] The overlapping body is provided to install the lower elastic rope body in the through hole on the overlapping body, so as to avoid the lower elastic rope body 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.

[0011] According to one embodiment of the present invention, the limiting plate array is arranged on the elastic rope body, the limiting plate body is provided with first through holes opposite to each other, a second through hole is provided between the first through holes, the diameter of the first through hole is larger than the diameter of the elastic rope body, a connecting rope is connected to the second through hole, a floating body is connected to the connecting rope, 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 arranged above the elastic rope body.

[0012] The elastic rope body slides violently, and the first roller and the second roller are both set as rollers with diameters on both sides larger than the middle diameter, so that the elastic rope body can be always located on the rollers without falling off. In addition, the elastic rope body is composed of two rope bodies arranged opposite to each other, and the two rope bodies are connected by a limiting plate body. The diameter of the first through hole is larger than the diameter of the elastic rope body, so that the elastic rope body has free space in the first through hole. At the same time, the two rope bodies pass through the two first through holes on the limiting plate body, which can also avoid the phenomenon that the two rope bodies are separated by a long distance and uneven force causes the elastic rope body to escape from the first roller and the second roller. When in use, since algae will be entangled on the rope body, the evenly arranged limiting plates will not slide together. The floating body is tied to the second through hole through a connecting rope, and personnel can judge the distribution of underwater seaweed by the sinking degree of the floating body. Because the floating body exerts a buoyancy pull on the upper elastic rope body, the upper elastic rope body can carry more seaweed, which indirectly increases the seaweed purification rate on the upper water surface. At the same time, the buoy located on the water surface can serve as a dividing line to divide the water body into two parts. Personnel can observe and detect the water quality on both sides more intuitively based on the buoy.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The weight difference between the upper and lower parts of the elastic rope due to the different weight of the seaweed can keep the elastic rope in a state of dynamic balance. During the movement of the elastic rope, the seaweed will be moved from the water depth with more algae to the water depth with less algae. At the same time, the seaweed broken on the elastic rope will be redistributed to different depths and positions due to the increase of its own weight. This can make the algae spread all over the water depths. In addition, the design of the net and the weighted ball can make the nitrogen, phosphorus and other substances deposited in the mud and sediment at the bottom of the water float again in the water, and then be purified and absorbed by the algae.

[0014] The personnel can judge the distribution of underwater seaweed by the sinking degree of the floating body, and because of the pulling force of the floating body on the elastic rope, the upper elastic rope can carry more seaweed, which indirectly increases the seaweed purification rate on the upper water surface. At the same time, the floating body can serve as a dividing line to help personnel more intuitively observe and detect the water quality on both sides of the floating body.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0020] Embodiment 1 See attached Figure 1-Figure 7As shown, a sinkable suspended seaweed ecological restoration device comprises a first roller 101 and a second roller 102 arranged oppositely, and an elastic rope 103 wound on the first roller 101 and the second roller 102, a floating body 10 is arranged on the elastic rope 103, the elastic rope 103 is two rope groups arranged oppositely, and a limiting plate 201 is arranged on the elastic rope 103. Both rollers are provided with a roller frame, the first roller 101 and the second roller 102 are arranged above the water surface, and the roller frames of the first roller 101 and the second roller 102 can be buried on the shore or fixed on a ship, the floating body 10 can use buoyancy to improve the carrying capacity of the upper part of the elastic rope 103 for seaweed, and the limiting plate 201 is used to keep the two parts of the rope body constituting the elastic rope 103 at a certain distance, so as to prevent the elastic rope 103 from escaping from the first roller 101 and the second roller 102.

[0021] The elastic rope body 103 is provided with a lap body 20 below. The lap body 20 is a square cylinder with a curved surface at the top. The side wall of the square cylinder is provided with a through hole. The through hole is provided on the curved surface of the square cylinder. The lap body 20 is relatively arranged at the lower side of the first roller 101 and the second roller 102. The lap 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 lap body 20 is fixedly buried on the seabed close to the first roller 101 and the second roller 102. The upper curved surface of the lap body is partially exposed on the seabed. In waters with rapid water flow, since the elastic rope body 103 is arranged inside the through hole, the displacement of the elastic rope body 103 will be limited to prevent the elastic rope body 103 from falling off the lap body 20. The elastic rope body 103 is provided with a net body 301 below. A counterweight ball 302 is fixedly provided at the end of the net body 301.

[0022] In the marine seawater or lake freshwater environment, there are often many seaweeds. These seaweeds are often located at different depths in the water resources according to the living environment, water resources or seaweed species. Most seaweeds are generally long in shape and easy to be entangled on the rope. When the elastic rope body 103 is installed, since the elastic rope body 103 is installed around the first roller 101 and the second roller 102, the two rollers divide the elastic rope body 103 into two parts, the upper part is closer to the water surface, and the lower part is farther from the water surface and naturally sinks in the water. During the flow of seaweed and water, the seaweed will be entangled on the upper and lower parts of the elastic rope body 103. Since the types and quantities of seaweed at different depths are different, when the seaweed is entangled on the upper and lower parts of the elastic rope body 103, there will be a weight difference between the upper and lower parts of the rope body, and the elastic rope body 103 will slide along the first roller 101 and the second roller 102 until the weight is balanced. And because the movement of the seaweed and the flow of the water are continuous, the upper and lower parts of the elastic rope body 103 will be in a state of dynamic balance. In the process of maintaining this dynamic balance, the elastic rope body 103 will move up and down continuously, and will move the seaweed from the water depth layer with more algae to the water depth layer with less algae. At the same time, in the process of the movement of the elastic rope body 103, since the elastic rope body 103 itself has a certain elasticity, the entangled algae may slide or break and fall off from the elastic rope body 103. After falling off, due to the increase in the dead weight of the entangled algae, it is placed in different water depths, and the algae in the water can be redistributed to different depths and different positions. This can be repeated, so that the algae can be distributed in different water depths in the water body, thereby achieving the effect of purifying the water body.

[0023] 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, and algae plants cannot purify nitrogen, phosphorus and other substances located on the bottom of the water because they float in 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 making the nitrogen, phosphorus and other substances located at the bottom of the water 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 larger, so that algae with low biological activity or dead algae can be removed.

[0024] 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 worn due to long-term friction caused by the bottom support, and reduce the possibility of the elastic rope body 103 sliding unsmoothly due to friction.

[0025] The limiting plate bodies 201 are arranged in an array on the elastic rope body 103. The limiting plate bodies 201 are provided with first through holes 202 opposite to each other. Second through holes 203 are provided between the first through holes. The diameter of the first through holes 202 is larger than the diameter of the elastic rope body 103. The second through holes 203 are connected with connecting ropes 105. The connecting ropes 105 are connected with the floating body 10. The bottom end of the floating body 10 is fixedly provided with a connecting ring 104. The connecting rope 105 is fixedly connected to the connecting ring 104. The floating body 10 is arranged in an array above the elastic rope body 103.

[0026] The elastic rope 103 slides violently, and the first roller 101 and the second roller 102 are both set as rollers with diameters on both sides larger than the middle diameter, so that the elastic rope 103 can be always located on the rollers and does not fall off. In addition, the elastic rope 103 is composed of two ropes arranged opposite to each other, and the two ropes are connected by a limiting plate 201. The diameter of the first through hole 202 is larger than the diameter of the elastic rope 103, so that the elastic rope 103 has free space in the first through hole 202. At the same time, the two ropes pass through the two first through holes 202 on the limiting plate 201, which can also avoid the phenomenon that the two ropes are separated by a long distance, resulting in uneven force and the elastic rope 103 falling off the first roller 101 and the second roller 102. When in use, since algae will be entangled on the rope, the evenly arranged limiting plates 201 will not slide together. The float 10 is tied to the second through hole 203 by the connecting rope 105. The personnel can judge the distribution of underwater seaweed by the sinking degree of the float 10. Because the float 10 exerts a buoyancy force on the upper elastic rope 103, the upper elastic rope 103 can carry more seaweed, which indirectly increases the seaweed purification rate on the upper water surface. At the same time, the float 10 located on the water surface can be used as a dividing line to divide the water body into two parts. The personnel can observe and detect the water quality on both sides more intuitively according to the float 10.
