Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to an ecological restoration device for damaged coastal wetlands. Background Art

[0002] As one of the important ecosystems on the earth, coastal wetlands play an irreplaceable and key role in maintaining biodiversity, regulating climate, purifying water quality and resisting natural disasters. However, in recent years, with the acceleration of urbanization, the frequent development of industrial activities and human development and utilization, the ecological environment of coastal wetlands is facing serious threats and damage. In order to restore the ecological functions of coastal wetlands, traditional ecological restoration methods are widely used. Among them, ecological restoration devices occupy an important position in wetland restoration work. In traditional restoration, floating beds or suspended beds are often used to purify water quality, and then the bottom sludge is cleaned regularly to remove nitrogen and phosphorus nutrients in the water.

[0003] The current ecological restoration device has a suspended bed installed at the bottom. When the flowing water contacts the suspended bed, the silt impurities in the water will be deposited. The deposited silt forms a mound, which accumulates more and more. Excessive silt will affect the growth of submerged plants on the suspended bed, and may affect its ecological restoration effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an ecological restoration device for damaged coastal wetlands that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An ecological restoration device for damaged coastal wetlands comprises: a floating bed and a suspended bed, and also comprises: a dredging plate arranged on the lower side of the suspended bed; a plurality of square grooves equidistantly provided on the dredging plate; a connecting assembly arranged between the floating bed and the dredging plate; and a plurality of insert blocks fixedly arranged on the lower side of the dredging plate, wherein the insert blocks are provided with an insertion surface and an arcuate surface.

[0007] Furthermore, the floating bed includes floating blocks, and a plurality of equally spaced planting blocks are arranged in the floating blocks. The suspended bed includes suspended blocks, and a planting layer is arranged in the suspended blocks.

[0008] Preferably, the connecting assembly includes a plurality of limiting sleeves arranged on the dredging plate, a piston rod is sealingly and slidingly connected inside the limiting sleeve, a plurality of first limiting ears are fixedly connected to the floating block, the piston rod is connected to the first limiting ear, a first pull rope is fixedly connected between the piston rod and the first limiting ear, and a second pull rope is fixedly connected between the bottom of the limiting sleeve and the dredging plate.

[0009] In order to adapt to wind, waves and rising water environments, an exhaust pipe is further provided in the piston rod, and the end of the piston rod is fixedly connected to an extension pipe connected to the exhaust pipe. A first circular hole corresponding to the extension pipe is provided on the first limiting ear, and an exhaust pipe is provided at the lower end of the limiting sleeve. A tension spring is fixedly connected between the piston rod and the limiting sleeve, and a one-way valve is provided in both the exhaust pipe and the exhaust pipe.

[0010] In order to ensure that the distance between the suspended bed and the water surface remains consistent and that it receives light evenly, a plurality of connecting steel wires are fixedly connected between the floating block and the suspended block.

[0011] Preferably, a plurality of second limiting ears corresponding to the limiting sleeves are fixedly connected around the periphery of the suspension block, and a second circular hole is provided on the second limiting ears.

[0012] In order to facilitate limiting the shaking of the suspended bed, a movable gap is further provided between the second circular hole and the limiting sleeve.

[0013] In order to facilitate the provision of oxygen for the submerged plants in the hanging bed, further, a mesh tube is provided on the hanging bed, and a plurality of nozzles arranged at equal intervals are provided on the mesh tube, and the end of the exhaust pipe is connected to the mesh tube.

[0014] In order to facilitate the positioning of the dredging plate, a plurality of fixing ears are fixedly connected to the dredging plate, mounting holes are symmetrically provided on the fixing ears, anchor rods are slidably provided in the mounting holes, and a connecting plate is fixedly connected between the tops of two adjacent anchor rods, and there is a gap between the anchor rods and the mounting holes.

[0015] In order to expand the dredging range, a plurality of sub-plates are further provided around the dredging plate, and the sub-plates are fixedly connected to the dredging plate by bolts.

[0016] Compared with the existing technology, the present invention provides an ecological restoration device for damaged coastal wetlands, which has the following beneficial effects:

[0017] 1. The ecological restoration device for damaged coastal wetlands purifies water quality through the roots of plants planted in the planting blocks. The suspended bed is suspended at a certain depth in the water body, and the plants in the planting layer also participate in water purification, so that different water layers can be purified synchronously. When there are waves generated by wind or water flow, the waves impact the floating blocks of the floating bed, causing one side of the entire floating bed to slightly lift up or shake downward. When the floating bed shakes, the floating bed pulls the silt removal plate upward through the connecting assembly. In the process of the silt removal plate shaking upward, the plug inserted in the silt is pulled out, and part of the deposited silt is lifted upward, so that it flows with the water flow, thereby effectively solving the problem of serious local silt deposition after hanging bed planting, and at the same time preventing excessive silt on the lower side of the hanging bed from affecting the growth of plants on the hanging bed.

[0018] 2. The ecological restoration device for damaged coastal wetlands floats upward as the water level rises. At this time, the floating bed pulls the piston rod upward through the first pull rope to slide, so that it can adapt to different water level changes. When there are wind and waves, the floating bed is in rapid shaking. At this time, the suction speed of the suction pipe is lower than the suction speed required for the piston rod to move, so that the limiting sleeve pulls the silt removal plate upward to shake for silt removal, thereby ensuring the stability and reliability of the ecological restoration device in complex coastal wetland environments and preventing the floating bed from being submerged.

[0019] 3. The ecological restoration device for damaged coastal wetlands can draw external gas into the limiting sleeve through the movement of the piston rod and the exhaust pipe, and then continuously transport the gas into the mesh tube through the exhaust pipe, and finally eject it through the nozzle of the mesh tube. On the one hand, it can blow out the silt deposited on the bottom, and on the other hand, it can achieve an oxygenation effect, increase the activity of submerged plants, and thus improve its ecological restoration effect.

[0020] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The present invention effectively solves the problem of serious local deposition of silt after hanging bed planting, and at the same time prevents excessive silt on the lower side of the hanging bed from affecting the growth of plants on the hanging bed.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 An ecological restoration device for damaged coastal wetlands includes: a floating bed 1 and a suspended bed 2, and also includes: a silt removal plate 3, which is arranged on the lower side of the suspended bed 2; a plurality of square grooves 301, which are equidistantly opened on the silt removal plate 3; a connecting component, which is arranged between the floating bed 1 and the silt removal plate 3; and a plurality of plug blocks 302, which are fixedly arranged on the lower side of the silt removal plate 3, and the plug blocks 302 are provided with an insertion surface 303 and an arcuate surface 304.

[0031] The floating bed 1 includes floating blocks 102 , in which a plurality of equally spaced planting blocks 101 are arranged. The suspended bed 2 includes suspended blocks 202 , in which a planting layer 201 is arranged.

[0032] In a specific embodiment, the floating bed 1 floats on the water surface, and the water quality is purified by the roots of plants planted in the planting blocks 101. The suspended bed 2 is suspended at a certain depth in the water body, and the plants in the planting layer 201 also participate in water purification, so that different water layers can be purified synchronously. When there are waves generated by wind or water flow, the waves hit the floating blocks 102 of the floating bed 1, causing one side of the entire floating bed 1 to slightly lift up or shake downward. When the floating bed 1 shakes, the floating bed 1 pulls the silt removal plate 3 upward through the connecting assembly. During the upward shaking process of the silt removal plate 3, the plug 302 inserted in the silt is pulled out. At this time, part of the deposited silt is lifted upward and flows with the water flow, thereby effectively solving the problem of serious local silt deposition after the suspended bed 2 is planted, and at the same time, it can prevent excessive silt on the lower side of the suspended bed 2 from affecting the growth of plants on the suspended bed 2.

[0033] Example 2: Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an ecological restoration device for damaged coastal wetlands, which is basically the same as Example 1, further, the connecting assembly includes a plurality of limiting sleeves 4 arranged on the dredging plate 3, a piston rod 401 is sealingly and slidingly connected inside the limiting sleeve 4, a plurality of first limiting ears 103 are fixedly connected to the floating block 102, the piston rod 401 is connected to the first limiting ear 103, a first pull rope 405 is fixedly connected between the piston rod 401 and the first limiting ear 103, and a second pull rope 406 is fixedly connected between the bottom of the limiting sleeve 4 and the dredging plate 3.

[0034] An exhaust pipe 403 is provided in the piston rod 401, and the end of the piston rod 401 is fixedly connected to an extension pipe 407 connected to the exhaust pipe 403. A first circular hole 104 corresponding to the extension pipe 407 is provided on the first limiting ear 103, and an exhaust pipe 404 is provided at the lower end of the limiting sleeve 4. A tension spring 402 is fixedly connected between the piston rod 401 and the limiting sleeve 4, and a one-way valve is provided in the exhaust pipe 404 and the exhaust pipe 403.

[0035] In actual application, as the water level rises, the floating bed 1 floats upward. At this time, the floating bed 1 pulls the piston rod 401 upward through the first pull rope 405 to slide, so that it can adapt to different water level changes. When there are wind and waves, since the floating bed 1 is in rapid shaking, the suction speed of the exhaust pipe 403 is less than the suction speed required for the piston rod 401 to move, so that the limiting sleeve 4 pulls the silt removal plate 3 upward to shake upward for silt removal, thereby ensuring the stability and reliability of the ecological restoration device in complex coastal wetland environments and preventing the floating bed 1 from being flooded.

[0036] Example 3: Reference Figure 3 , an ecological restoration device for damaged coastal wetlands, which is basically the same as Example 1, furthermore, a plurality of connecting steel wires 208 are fixedly connected between the floating block 102 and the suspended block 202.

[0037] The connection wire 208 can ensure that the suspended bed 2 always maintains the same distance from the water surface, thereby allowing it to receive sufficient sunlight and preventing the water level from rising and affecting the photosynthesis of the submerged plants on the suspended bed 2.

[0038] A plurality of second limiting ears 203 corresponding to the limiting sleeve 4 are fixedly connected to the periphery of the suspension block 202 , and a second circular hole 204 is provided on the second limiting ears 203 .

[0039] A movable gap 205 is provided between the second circular hole 204 and the limiting sleeve 4 .

[0040] The second circular hole 204 can be used to limit the suspended bed 2 to prevent the suspended bed 2 from shaking too much when the floating bed 1 shakes, and the movable gap 205 can be set to control the shaking range of the suspended bed 2, thereby ensuring the shaking of the suspended bed 2 while reducing its shaking amplitude.

[0041] When the suspended bed 2 is shaken, the silt impurities attached to and deposited on the submerged plants on the suspended bed 2 are scattered and mixed in the water, accompanied by the flow of water, thereby effectively preventing excessive silt impurities attached to the submerged plants from affecting their ecological restoration efficiency, and at the same time effectively preventing the roots of the submerged plants from rotting in a nutrient-rich sludge environment for a long time.

[0042] Example 4: Reference Figure 1-Figure 7 , an ecological restoration device for damaged coastal wetlands, which is basically the same as Example 1, and further, a mesh tube 206 is provided on the suspended bed 2, and a plurality of equidistantly arranged nozzles 207 are provided on the mesh tube 206, and the end of the exhaust pipe 404 is connected to the mesh tube 206.

[0043] Through the movement of the piston rod 401 and the exhaust pipe 403, the external gas can be sucked into the limiting sleeve 4, and then the gas is continuously transported to the mesh tube 206 through the exhaust pipe 404, and finally ejected through the nozzle 207 of the mesh tube 206. On the one hand, the silt deposited at the bottom can be blown out, and on the other hand, the oxygenation effect can be achieved, thereby increasing the activity of submerged plants and thereby improving its ecological restoration effect.

[0044] A plurality of fixing ears 305 are fixedly connected to the dredging plate 3, and mounting holes 310 are symmetrically provided on the fixing ears 305. Anchor rods 306 are slidably provided in the mounting holes 310, and a connecting plate 307 is fixedly connected between the tops of two adjacent anchor rods 306, and there is a gap between the anchor rods 306 and the mounting holes 310.

[0045] During the actual installation process, the dredging plate 3 is installed underwater through the anchor rod 306, and the connection is not limited to the use of foundation piles. During the connection, the gap between the anchor rod 306 and the installation hole 310 ensures that the dredging plate 3 can be tilted and lifted to adapt to the shaking of the dredging plate 3 driven by waves in different directions, and the dredging plate 3 will also lift up the silt at the bottom after falling after shaking upwards, thereby effectively preventing the deposition of silt.

[0046] In actual application, special dredging equipment is set up at the confluence of water flows to carry out dredging.

[0047] A plurality of sub-plates 308 are provided around the silt cleaning plate 3 , and the sub-plates 308 are fixedly connected to the silt cleaning plate 3 by bolts 309 .

[0048] Sub-plates 308 of different sizes can be installed around the dredging plate 3, wherein the lower end of the sub-plate 308 also has an insert 302, which can provide dredging over a large area. Different sub-plates 308 are matched according to the specific planting positions of the floating bed 1 and the suspended bed 2. When the distance between adjacent floating beds 1 is far, a larger sub-plate 308 can be installed.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
