Description

Technical Field

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

[0002] Bottom mud, the sediments of rivers and lakes, is a vital component of natural water bodies. When water bodies become polluted, some pollutants can accumulate in the bottom mud through precipitation or adsorption by particulate matter. Under appropriate conditions, they can be released again, becoming a source of secondary pollution. This type of pollution is called bottom mud pollution.

[0003] In the river environment, riverbed sediments are transported in the form of displacement and suspension, which to a large extent leads to the physical interaction between overlying water and sediments. Rivers have a strong natural environment, which tends to be conducive to the desorption of sediments in the river system, thereby affecting the water quality of the overlying water. Pollutants can be retained, accumulated and migrated in organisms through biological metabolism, causing toxic and teratogenic hazards, which not only harm the benthic organisms in the river, but also seriously threaten people's health.

[0004] Riverbed sediment remediation and treatment technology At present, there are two main methods for riverbed sediment remediation and treatment: in-situ remediation and ex-situ remediation. In-situ remediation mainly involves the remediation and treatment of the sediment in the original location of the river. The main methods used include physical, chemical, biological, etc., to adsorb and degrade pollutants in the sediment to improve the water quality of the river. Ex-situ remediation is a treatment technology that is currently used with high frequency. First, the riverbed sediment is dug out, and then the sediment is treated by biological or chemical methods. The treated sediment needs to be landfilled. Ex-situ remediation can effectively remove contaminated sediment in the river, but there are many ways to treat the excavated sediment. If not handled properly, it will cause secondary pollution to the environment and affect the balance of the surrounding natural environment.

[0005] At present, in-situ biological restoration is generally achieved by placing ecological restoration boards filled with vegetation in the river channel, and achieving the purpose of restoration through biological decomposition and transformation. However, since the biological restoration boards do not have a good positioning and fixing structure, the ecological restoration boards are unstable, resulting in unstable biological rooting, affecting the restoration effect. In addition, the ecological restoration boards do not have a structure to protect the vegetation on top, resulting in the vegetation being greatly affected by water flow or disturbance, making the vegetation easy to fall off, which is not conducive to vegetation growth. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a river ecological restoration device to solve the problem that the existing ecological restoration panels are not conducive to positioning and fixation and the growth of vegetation thereon.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A river channel ecological restoration device, applied to river channel bottom sediment, includes an ecological restoration plate, with multiple guide plates higher than the top surface of the ecological restoration plate provided around the ecological restoration plate. The side of the guide plate facing away from the ecological restoration plate has an arc-shaped guide surface. The multiple guide plates enclose a stable flow area on the top of the ecological restoration plate. A stable flow baffle with a height less than or equal to that of the guide plate is provided in the stable flow area. The stable flow baffle separates the top of the ecological restoration plate into multiple stable flow grids, each of which is provided with a biological placement area.

[0009] At least one opposite side of the ecological restoration board is symmetrically provided with a positioning support assembly, and the positioning support assembly includes a mounting rod parallel to the corresponding side of the ecological restoration board, and the mounting rod is rotatably connected to the ecological restoration board through at least one elastic buffer member, and counterweight blocks are respectively connected to both ends of the mounting rod, and a positioning seat is provided in the middle of the mounting rod, and the bottom of the positioning seat has a supporting surface, and a plurality of positioning rods for inserting into the riverbed mud are evenly distributed on the supporting surface.

[0010] In a possible implementation, the positioning rod includes a rod body having a pointed tip at its bottom end and at least one inverted annular conical protrusion arranged axially along the rod body.

[0011] In a possible implementation, the elastic buffer includes an inner telescopic rod and an outer telescopic tube, one end of the inner telescopic rod is rotatably connected to the ecological restoration plate, the other end of the inner telescopic rod is slidably fitted in one end of the outer telescopic tube, and the other end of the outer telescopic tube is connected to the mounting rod; a buffer spring is provided in the outer telescopic tube, the top of the buffer spring abuts against the bottom of the inner telescopic rod, and the bottom of the buffer spring abuts against the inner bottom of the outer telescopic tube.

[0012] In a possible implementation, the ecological restoration plate is provided with a mounting groove corresponding to each elastic buffer member, a rotating shaft is provided in the mounting groove, and the inner telescopic rod is connected to a rotating sleeve and is rotatably connected to the rotating shaft through the rotating sleeve.

[0013] In a possible implementation, the ecological restoration board is rectangular, a guide plate is provided on each of the four sides of the ecological restoration board, and the positioning support assembly is provided on each of the two width sides of the ecological restoration board.

[0014] In a possible implementation, at least one side of the ecological restoration board is provided with an airbag assembly;

[0015] The airbag assembly includes a storage shell with a storage cavity, the storage shell is provided with a storage port connected to the storage cavity, an inflatable bag is provided in the storage cavity, and arc-shaped cover plates are connected to both sides of the storage port through a rotating shaft. The arc-shaped cover plates on both sides are symmetrically arranged and a torsion spring is provided on the outside of the rotating shaft so that the arc-shaped cover plates have a tendency to flip inward; the inner side of the arc-shaped cover plate is connected to an elastic rope and is connected to the outer surface of the inflatable bag through the elastic rope.

[0016] In a possible implementation, the inflatable bag is folded in an S shape in the storage cavity, and the inflatable bag has an inflation port and an exhaust port, the inflation port is sealed and connected to an inflation tube, the inflation tube is connected to a one-way valve and connected to an air intake connecting tube through the one-way valve, and the air intake connecting tube is used to connect the inflation device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The river ecological restoration device of the present invention arranges guide plates on the peripheral sides of the ecological restoration plate. The guide plates can reduce the disturbance effect of the river water on the ecological restoration plate through the guide surface, and can also form a stable flow area on the inner side of the guide plate that is conducive to stable flow.

This not only facilitates the stability of the posture of the ecological restoration board when it sinks and during the restoration process, so that its top surface is always facing upward, but also enables the multiple positioning rods of the positioning seat to be inserted into the bottom mud for better positioning. It is also more stable when the water flow rate is large. The support surface of the mounting seat can also prevent the positioning support assembly from sinking into the bottom mud and being unable to effectively support it. Moreover, through the elastic support and elastic expansion of multiple elastic buffers, the ecological restoration board can better cope with the multi-angle and multi-directional disturbance of the water body, provide a buffering effect, and enable the ecological restoration board to maintain a basically stable posture, which is very beneficial to the ecological restoration of vegetation.

[0021] In addition, the ecological restoration board is equipped with an airbag assembly, which is convenient for the storage of the airbag and the expansion and deployment of the airbag after inflation. The airbag can be used to control the air pressure, so that the ecological restoration board can be raised or lowered, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] The ecological restoration of riverbed sediments is currently generally carried out by placing ecological restoration boards filled with vegetation in the river, and achieving the purpose of restoration through biological decomposition and transformation. However, since the biological restoration boards do not have a good positioning and fixing structure, the ecological restoration boards are unstable, resulting in unstable biological rooting, affecting the restoration effect. In addition, the ecological restoration boards do not have a structure to protect the vegetation on top, resulting in the vegetation being greatly affected by water flow or disturbance, making the vegetation easy to fall off, which is not conducive to vegetation growth.

[0033] In order to solve the above technical problems, the technical solution of the present application solves the problem from many aspects: 1. Since the vegetation needs to be set on the top of the ecological restoration board and the fixation is mostly simple, when facing water flow or disturbance, it has a great impact on the vegetation and is easy to fall off. Therefore, the impact of water flow or disturbance on the vegetation is reduced to a great extent. By arranging diversion components and separated and low components on the inner side of the ecological restoration board, several areas that can achieve stable flow of water in small areas can be formed on the ecological restoration board, and vegetation can be arranged in these areas. This can greatly reduce the impact of water flow or disturbance on vegetation, thereby facilitating the growth of vegetation and avoiding the problem of easy falling off of vegetation; 2. The plate-like structure of the ecological restoration board will swing or rotate irregularly when sinking or rising and when disturbed by water, resulting in its posture cannot be maintained stable and its top surface cannot be facing upward, even after sinking. Better fixing effect leads to instability, and the movable component with counterweight effect can make its top surface basically face upward when sinking, rising or disturbed by water, so as to maintain its posture, and when sinking to the bottom mud, the support surface of the positioning seat can play a better supporting role, preventing the positioning seat from sinking completely into the bottom mud, and the positioning component of the support surface can be inserted into the bottom mud to play a better fixing role, thereby achieving stability of the ecological restoration board, better responding to water flow or disturbance, and more conducive to vegetation growth and restoration. At the same time, by making the component and the ecological restoration board have elastic support to achieve buffering components, the impact of water flow or disturbance on the ecological restoration board can be reduced, and it can also be stretched and contracted accordingly to respond to forces from multiple directions to achieve better buffering. The more the number of them is set along the circumference, the better the buffering effect, and thus the stability of the ecological restoration board can be effectively maintained.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Please refer to Figure 1-5 As shown, an embodiment of the present application provides a river ecological restoration device for use in riverbed sediment, comprising an ecological restoration plate 1. Vegetation can be arranged on the ecological restoration plate 1, and a root guide hole or a root guide tube is provided at the bottom. Meanwhile, growth materials required for vegetation growth are also preset in the ecological restoration plate 1.

[0036] A river channel ecological restoration device according to an embodiment of the present application is provided with a plurality of guide plates 2 higher than the top surface of the ecological restoration plate 1 on the peripheral side of the ecological restoration plate 1, the guide plate 2 having an arc-shaped guide surface 21 on the side facing away from the ecological restoration plate 1, and a plurality of guide plates 2 are enclosed on the top of the ecological restoration plate 1 to form a steady flow area, a steady flow baffle 3 having a height less than or equal to that of the guide plate 2 is provided in the steady flow area, the steady flow baffle 3 separates the top of the ecological restoration plate 1 into a plurality of steady flow grids, and each steady flow grid is provided with a biological placement area 4.

[0037] The guide plate 2 functions as a flow barrier and stabilizer. It also diverts or guides water through its curved guide surface 21, diverting lateral water flow upward and downward. This diversion reduces the impact of water flow or disturbances on the ecological restoration plate 1, making it more stable. The peripheral guide plates 2 form a preliminary stabilizing zone within the plate, while the stabilizing baffles 3 further form multiple stabilizing grids with the guide plates 2 to stabilize small areas of water. By providing biological placement areas 4 for placing vegetation within the stabilizing grids, the vegetation has a more stable growth environment, further facilitating ecological restoration.

[0038] At least one opposite side of the ecological restoration board 1 is symmetrically provided with a positioning support assembly 5, and the positioning support assembly 5 includes a mounting rod 51 parallel to the corresponding side of the ecological restoration board 1, and the mounting rod 51 is rotatably connected to the ecological restoration board 1 through at least one elastic buffer 52. Counterweight blocks 55 are respectively connected to both ends of the mounting rod 51, and a positioning seat 54 is provided in the middle of the mounting rod 51. The bottom of the positioning seat 54 has a support surface 56, and a plurality of positioning rods 57 for inserting into the riverbed mud are evenly distributed on the support surface 56.

[0039] The positioning support assembly 5 is provided with two groups and is respectively arranged on two opposite sides, which is conducive to the stability of the ecological restoration board 1. The mounting rod 51 is rotatably connected to the ecological restoration board 1 through an elastic buffer 52. The rotatable connection can make the ecological restoration board 1 more mobile, which is conducive to adapting to the flowing or disturbed water environment, and the counterweight block can provide it with a stable foundation. The elastic buffer 52 can realize elastic support and buffering of the ecological restoration board 1, and is also conducive to responding to disturbances at multiple angles through elastic expansion and contraction, thereby better maintaining stability. The bottom surface of the positioning seat 54 is a support surface 56, which has a basic contact area, and its area can be determined according to the overall gravity. The support surface 56 can prevent the positioning seat 54 from sinking into the bottom mud, and the positioning rod 57 provided on the support surface 56 can play a fixing role, so that the ecological restoration board 1 is more stable under the influence of water flow or disturbance.

[0040] Through the above-mentioned technical solution, a guide plate 2 is set on the peripheral side of the ecological restoration plate 1. While the guide plate 2 can reduce the disturbance effect of the river water on the ecological restoration plate 1 through the guide surface 21, it can also form a stable flow area on the inner side of the guide plate 2 that is conducive to stable flow. With the cooperation of the stable flow baffle 3, the water body in the stable flow grid where each biological placement area 4 is located can have a more stable state, which is beneficial to the growth of vegetation and avoids the problem of vegetation easily falling off and affecting growth. Moreover, by arranging positioning support components 5 on both sides of the ecological restoration board 1, the positioning support components 5 are rotatable and are provided with counterweight blocks 55. This not only facilitates the stability of the posture of the ecological restoration board 1 when it sinks and during the restoration process, so that its top surface is always facing upward, but also can be inserted into the bottom mud through multiple positioning rods 57 of the positioning seat 54 for better positioning. It is also more stable when the water flow rate is large. The support surface 56 of the mounting seat can also prevent the positioning support component 5 from sinking into the bottom mud and being unable to effectively support it. Moreover, through the elastic support and elastic expansion of multiple elastic buffers 52, the ecological restoration board 1 can better cope with the multi-angle and multi-directional disturbance of the water body, provide a buffering effect, and enable the ecological restoration board 1 to maintain a basically stable posture, thereby greatly benefiting the ecological restoration of vegetation.

[0041] In one embodiment, the positioning rod 57 includes a rod body 571 with a pointed tip at the bottom end and at least one inverted annular conical protrusion 572 axially arranged along the rod body 571 .

[0042] The rod body 571 with a pointed end can be easily inserted into the bottom mud. After being inserted into the bottom mud, the inverted annular conical protrusion 572 can play a certain anti-pullout role, thereby making the ecological restoration board 1 more stable.

[0043] Furthermore, to better achieve the functions of elastic support and buffering, the elastic buffer member 52 includes an inner telescopic rod 521 and an outer telescopic tube 522. One end of the inner telescopic rod 521 is rotatably connected to the ecological restoration board 1, and the other end of the inner telescopic rod 521 slides inside one end of the outer telescopic tube 522, the other end of which is connected to the mounting rod 51. A buffer spring 523 is provided inside the outer telescopic tube 522, the top of which abuts the bottom of the inner telescopic rod 521, and the bottom of which abuts the inner bottom of the outer telescopic tube 522. In this way, the sliding fit between the inner telescopic rod 521 and the outer telescopic tube 522 allows for telescopic expansion and contraction, and the built-in buffer spring 523 enables elastic expansion and contraction and elastic buffering.

[0044] Furthermore, the ecological restoration board 1 has a mounting slot corresponding to each elastic buffer 52, a rotating shaft is provided in the mounting slot, and the inner telescopic rod 521 is connected to a rotating sleeve 53 and is rotatably connected to the rotating shaft via the rotating sleeve 53. This allows the elastic buffer 52 to rotate better, thereby facilitating the rotation of the positioning support assembly 5.

[0045] During the specific implementation process, the bottom of the outer telescopic cylinder 522 is also rotatably connected to the mounting rod 51 through the mounting sleeve, which can improve the flexibility of the positioning support assembly 5 and easily maintain the stability of the posture through the support surface 56 in the water, thereby better positioning and fixing.

[0046] In an embodiment of the present application, the ecological restoration board 1 is rectangular, a guide plate 2 is provided on each of the four sides of the ecological restoration board 1, and the positioning support assembly 5 is provided on each of the two width sides of the ecological restoration board 1.

[0047] By arranging the structure in this way, the rectangular ecological restoration board 1 can have better diversion and positioning support functions, making it more stable.

[0048] Please refer to Figures 6-8. In the embodiment of the present application, an airbag assembly 6 is provided on at least one side of the ecological restoration board 1; the airbag assembly 6 includes a storage shell 61 having a storage cavity 62, and the storage shell 61 is provided with a storage port connected to the storage cavity 62. An airbag 63 is provided in the storage cavity 62, and an arc-shaped cover plate 64 is connected to both sides of the storage port through a rotating shaft. The arc-shaped cover plates 64 on both sides are symmetrically arranged and a torsion spring is provided on the outside of the rotating shaft so that the arc-shaped cover plate 64 has a tendency to flip inward; the inner side of the arc-shaped cover plate 64 is connected to an elastic rope 65 and is connected to the outer surface of the airbag 63 through the elastic rope 65.

[0049] The airbag assembly 6 is used to make the ecological restoration board 1 rise or fall, which is achieved by controlling the air pressure of its inflation. The airbag assembly 6 is provided with two groups and is respectively arranged on both sides where the positioning support assembly 5 is not provided. This can make the structure of the ecological restoration board 1 more balanced and the lifting more stable. The airbag 63 can be inflated and stored in the storage shell 61. The arc-shaped cover plate 64 of the storage shell 61 is an arc-shaped structure to match the state of inflation of the airbag 63. The arc-shaped cover plate 64 can be realized by the rotating shaft and the torsion spring to have a tendency to flip inward, and thus can have two states. One state is that when the airbag 63 is not inflated, the two arc-shaped cover plates 64 are closed to close the storage shell 61. The other state is in the inflated state. When the inflated airbag 63 expands, the arc-shaped cover plate 64 is squeezed and gradually flipped outward to match the expansion of the airbag 63. When the airbag is exhausted and stored, it can be facilitated to achieve automatic storage, which is more convenient and practical.

[0050] Furthermore, to better achieve automatic storage, an elastic cord 65 is connected to the inner side of the arc-shaped cover plate 64 and is connected to the outer surface of the inflatable bag 63 through the elastic cord 65. One end of the elastic cord 65 is connected to the middle or right part of the inflatable bag 63 in the uninflated state, and the other end is connected to the inner middle part of the arc-shaped cover plate 64. This allows the portion connected to the inflatable bag 63 to be better stored in the storage shell 61 by flipping the arc-shaped cover plate 64 inward when the inflatable bag 63 is deflated, thereby improving the storage effect and making it more convenient and practical.

[0051] In a specific implementation, the inflatable bag 63 is folded into an S-shape within the storage chamber 62 and has an inflation port 66 and an exhaust port. The inflation port 66 is sealedly connected to an inflation tube, which is connected to a one-way valve and, through the one-way valve, to an air inlet connection pipe, which is used to connect to an inflation device. The S-shaped folding structure facilitates the expansion of the inflatable bag 63. The inflation port 66 of the inflatable bag 63, connected to the inflation tube, the one-way valve, and the air inlet connection pipe, allows for reverse flow of the injected gas during inflation, making inflation more efficient. The exhaust port is used for exhaust and is provided with a sealing component. The inflation device is preferably an inflatable and deflable inflation device, which can facilitate controlling the air pressure within the inflatable bag 63 to control its elevation.

[0052] In the embodiment of the present application, airbag components 6 are provided on both sides of the ecological restoration board 1.

[0053] In this way, the airbag components 6 on both sides can make the ecological restoration board 1 more balanced and stable during the rising or falling process.

[0054] The river ecological restoration device of the embodiment of the present application has the following beneficial effects:

[0055] By arranging the guide plate 2 on the peripheral side of the ecological restoration plate 1, the guide plate 2 can reduce the disturbance effect of the river water on the ecological restoration plate 1 through the guide surface 21, and at the same time, it can form a stable flow area on the inner side of the guide plate 2 that is conducive to stable flow. With the cooperation of the stable flow baffle 3, the water body in the stable flow grid where each biological placement area 4 is located can be in a more stable state, which is conducive to the growth of vegetation and avoids the problem of vegetation easily falling off and affecting growth.

[0056] Moreover, by arranging positioning support components 5 on both sides of the ecological restoration board 1, the positioning support components 5 are rotatable and are provided with counterweight blocks 55. This not only facilitates the stability of the posture of the ecological restoration board 1 when it sinks and during the restoration process, so that its top surface is always facing upward, but also can be inserted into the bottom mud through multiple positioning rods 57 of the positioning seat 54 for better positioning. It is also more stable when the water flow rate is large. The support surface 56 of the mounting seat can also prevent the positioning support component 5 from sinking into the bottom mud and being unable to effectively support it. Moreover, through the elastic support and elastic expansion of multiple elastic buffers 52, the ecological restoration board 1 can better cope with the multi-angle and multi-directional disturbance of the water body, provide a buffering effect, and enable the ecological restoration board 1 to maintain a basically stable posture, thereby greatly benefiting the ecological restoration of vegetation.

[0057] In addition, the ecological restoration board 1 is provided with an airbag assembly 6, which is convenient for the storage of the inflatable bag 63 and the expansion and deployment of the inflatable bag 63 after inflation. The inflatable bag 63 can be used to control the air pressure, so that the ecological restoration board 1 can be raised or lowered, which is more convenient.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
