Description

Technical Field

[0001] The present invention relates to the technical field of mangrove wetland protection, and in particular to a method for rapidly restoring the ecological structure of degraded mangroves. Background Art

[0002] Mangroves are one of the most valuable forms of coastal wetlands. They serve as a buffer and transition zone between land and sea, and are an ideal home for countless benthic and marine organisms. The organic matter produced by mangroves is returned to the mudflats and ocean through litterfall, providing a substantial food source for organisms living there and significantly protecting and promoting biodiversity. In recent years, with the increasing population, rapid economic development, and rapid urbanization in coastal areas, coastal engineering construction, overdevelopment, and the increasing discharge of industrial wastewater, urban domestic wastewater, and agricultural wastewater, coastal mangrove wetlands have been severely damaged, with a sharp decrease in area, severe eutrophication of water and soil, and a decline in the integrity of biodiversity and ecological structure. Furthermore, numerous coastal industries and new coastal developments have generated large amounts of wastewater and industrial waste, ultimately leading to the collapse of the entire mangrove wetland ecosystem.

[0003] In the prior art, a Chinese patent application numbered CN202120892600.9 discloses a method for rapidly restoring the ecological structure of degraded mangroves. By injecting microbial agents into deep water and soil, organic pollutants are absorbed, transformed, and degraded, thereby repairing the ecological structure of the mangroves. Although it is possible to repair and manage the ecological structure of mangrove wetlands to a certain extent by laying a delivery pipeline under the tree planting area, laying a delivery pipeline in the soil is costly, and it is not easy to repair and treat the delivery pipeline when it is damaged; and because the roots of mangrove plants are not in a plane, but grow vertically from top to bottom, it is impossible to repair and manage silt layers of different depths and fully provide nutrients to the plant roots. It can only repair and manage silt at a single height, and the nutrient supply to the plant roots is not comprehensive, resulting in poor ecological restoration effects in mangrove wetlands. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a method for quickly restoring the ecological structure of degraded mangroves.

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

[0009] A protective tube, which is sleeved on the outside of the inner material tube and is used to prevent impurities in the water area to be repaired from entering the inner material tube;

[0010] Wherein, a driving component for driving the protective tube to move is provided in the material guiding tube.

[0011] Preferably, a connecting pipe is provided between the metal tube and the inner material tube, a plurality of evenly distributed first through holes are provided on the outer side of the inner material tube, and a plurality of second through holes cooperating with the first through holes are provided on the protective tube.

[0012] Preferably, the driving assembly includes a fixed seat fixed on the metal tube, the fixed seat is rotatably connected to a rotating shaft inside the metal tube, a torsion spring is arranged between the rotating shaft and the fixed seat, a paddle is arranged on the shaft body of the rotating shaft placed in the metal tube, and the end of the rotating shaft away from the fixed seat passes through the metal tube and is fixedly connected to the protective tube.

[0013] Preferably, a guide block for guiding the liquid is fixedly provided in the metal tube, and a movable groove for the movement of the connecting tube is provided on the top of the protective tube.

[0014] Preferably, a sleeve for covering the second through hole is provided on the outer side of the protective tube, a counterweight block is rotatably provided on the bottom of the sleeve, a movable tube is fixedly provided on the top of the sleeve, a telescopic rod is provided between the movable tube and the metal tube, and a movable groove is provided on the movable tube to cooperate with the metal tube.

[0015] Preferably, an air guide plate is provided on the top of the movable tube, and the bottom of the inner material tube is rotatably connected to the positioning rod.

[0016] Preferably, a bending and toggling rod is fixedly provided at the bottom of the inner material tube, and the bending and toggling rod moves in the silt layer at the bottom of the water area to be repaired.

[0017] Preferably, the bending and shifting rod includes an L-shaped connecting rod fixedly connected to the positioning rod, a plurality of movable tubes are sleeved on the L-shaped connecting rod, a coil spring is provided between each movable tube and the L-shaped connecting rod, and a shifting rod 122 is fixed on the movable tube.

[0018] Preferably, a water pump is further included, wherein the water outlet of the water pump is connected to the water inlet of the first material guide pipe, and the water inlet of the water pump is connected to a soil remediation agent box.

[0019] Preferably, it also includes a fence structure, which is arranged at the edge of the water area to be restored. The fence structure includes an artificial fence and / or an ecological fence. The artificial fence includes sandbags or mud bags, and the ecological fence is made of wooden piles or oyster shells.

[0020] Compared with the existing technology, the present invention provides a method for quickly restoring the ecological structure of degraded mangroves, which has the following beneficial effects:

[0021] 1. The degraded mangroves quickly restore their ecological structure. The inner material pipe is inserted into the silt layer in the water area to be restored through positioning rods. The soil remediation agent is more comprehensively transported to the silt layer using multiple inner material pipes connected by guide pipes. The soil remediation agent provides the elements required for the growth of mangrove plants, and the soil remediation agent effectively repairs and manages the silt in the water area, absorbs, transforms and degrades organic pollutants, with good economic, social and ecological benefits. At the same time, the inner material pipe uses a vertical plug-in method instead of being buried in the water and soil, which is convenient for timely treatment when the inner material pipe is damaged.

[0022] 2. The degraded mangrove quickly restores its ecological structure by arranging a protective tube on the outside of the inner material pipe. When the inner material pipe is not being repaired, the protective tube blocks the first through hole of the inner material pipe to prevent silt and impurities in the water from entering the inner material pipe, causing the inner material pipe to be blocked and affecting the subsequent repair and use of the inner material pipe; when the inner material pipe is being repaired, the soil remediation agent in the guide pipe impacts the toggle piece under the guidance of the guide block, so that the toggle piece drives the protective pipe to rotate through the rotating shaft. After the protective pipe rotates, the second through hole is aligned with the first through hole, so that the soil remediation agent that enters the inner material pipe from the guide pipe through the connecting pipe can flow out from the through hole. When the outflowing soil remediation agent repairs the wetland silt, it can simultaneously limit external substances from entering the inner material pipe through the through hole, thereby ensuring the continuous repair and use of the inner material pipe.

[0023] 3. The degraded mangrove quickly restores its ecological structure by arranging a casing on the outside of the protective pipe. The bottom of the casing is placed on the upper side of the silt through a counterweight block, so that the casing blocks the protective pipe body portion placed on the upper side of the silt, thereby avoiding the overlap of the through-holes of the protective pipe and the inner material pipe during the repair work, so that the soil repair agent also flows out of the through-holes of the protective pipe placed on the silt layer, resulting in a large amount of soil repair agent sprayed on the surface of the silt layer, causing waste of the soil repair agent. In addition, the casing can automatically adjust its height according to the insertion depth of the positioning rod under the action of the counterweight block, and has strong applicability.

[0024] 4. The degraded mangroves can quickly restore their ecological structure by setting an air guide plate on the top of the mobile tube. When the air guide plate is blown by the wind, it drives the mobile tube to rotate. The mobile tube drives the material guide tube to rotate through the telescopic rod. The material guide tube drives the protective tube and the inner material tube connected to it to rotate through the connecting tube, thereby automatically adjusting the outflow range of the soil remediation agent in the inner material tube, making the soil remediation range of the inner material tube more comprehensive, and effectively improving the restoration effect of the mangrove wetland.

[0025] 5. The degraded mangroves can quickly restore their ecological structure. By setting up artificial fences or ecological fences around the waters to be restored, they can serve as barriers to intercept garbage and further restore the ecological structure of the mangroves.

[0038] 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.

[0039] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0040] Example 1: Reference Figure 1-10 A method for rapidly restoring a degraded mangrove forest ecosystem comprises: a plurality of inner feed pipes 2 arranged in a water area 1 to be restored; and further comprising:

[0041] The material guide pipe 3 includes a metal pipe 301 connected to the inner material pipe 2 and a connecting hose 302 connected to both ends of the metal pipe 301. Two adjacent inner material pipes 2 are connected through the material guide pipe 3;

[0042] A positioning rod 4 is provided at the bottom of the inner tube 2 and is used to fix the inner tube 2 in the silt layer 101 in the water area 1 to be repaired; and

[0043] The protective tube 5 is sleeved on the outside of the inner material tube 2 and is used to prevent impurities in the water area 1 to be repaired from entering the inner material tube 2;

[0044] A driving assembly for driving the protective tube 5 to move is provided in the material guiding tube 3 .

[0045] Furthermore, a water pump 13 is included, the water outlet of the water pump 13 is connected to the water inlet of the first material guide pipe 3, and the water inlet of the water pump 13 is connected to the soil remediation agent box 131.

[0046] Furthermore, a connecting pipe 3011 is provided between the metal tube 301 and the inner material tube 2 , a plurality of evenly distributed first through holes 201 are opened on the outer side of the inner material tube 2 , and a plurality of second through holes 501 cooperating with the first through holes 201 are opened on the protective tube 5 .

[0047] Furthermore, the driving assembly includes a fixed seat 6 fixed on the metal tube 301, and the fixed seat 6 is rotatably connected to the metal tube 301 via a rotating shaft 601. A torsion spring 602 is provided between the rotating shaft 601 and the fixed seat 6. The rotating shaft 601 is placed on an axis in the metal tube 301 and a paddle 603 is provided. The end of the rotating shaft 601 away from the fixed seat 6 passes through the metal tube 301 and is fixedly connected to the protective tube 5.

[0048] Furthermore, a guide block 3012 for guiding the liquid is fixedly provided in the metal tube 301 , and a movable groove 502 for the movement of the connecting tube 3011 is provided on the top of the protective tube 5 .

[0049] Specifically, the staff evenly inserts multiple positioning rods 4 into the silt layer 101 in the water area 1 to be repaired, especially into the soil near the mangrove plants, so that multiple inner material tubes 2 are evenly distributed in the water area 1 to be repaired. Two adjacent inner material tubes 2 are connected by the guide tube 3. The protective tube 5 can block the first through hole 201 of the inner material tube 2 when no repair work is being carried out, so as to prevent silt and impurities in the water body from entering the inner material tube 2, causing blockage of the inner material tube 2 and affecting the subsequent repair and use of the inner material tube 2.

[0050] When performing the repair work, the water pump 13 is controlled to operate, and the water pump 13 extracts the soil repair agent inside the soil repair agent box 131 and transports it to the metal pipe 301 through the guide pipe 3. The soil repair agent drives the toggle piece 603 through the guiding effect of the guide block 3012, and the toggle piece 603 drives the protective pipe 5 to rotate through the rotating shaft 601, so that the protective pipe 5 rotates relative to the inner material pipe 2, and the second through hole 501 of the protective pipe 5 is aligned with the first through hole 201 of the inner material pipe 2. The soil repair agent in the metal pipe 301 is passed through the connecting pipe 301. 3011 enters the inner material pipe 2 and flows out through the through-hole. When the outflowing soil remediation agent impacts outward to repair the wetland water body and silt, it can also limit external substances from entering the inner material pipe 2 through the through-hole, ensuring the continuous repair and use of the inner material pipe 2. The soil remediation agent repairs the soil while providing the elements required for the growth of mangrove plants; the protection tube 5 and the through-hole arrangement of the inner material pipe 2 effectively avoid the need to set a valve or other sealing member at each through-hole of the inner material pipe 2 to intercept liquid or isolate silt, reducing the difficulty and cost of installation;

[0051] The present invention facilitates the uniform delivery of the soil remediation agent into the silt layer 101 through a plurality of inner material pipes 2, so that the soil remediation agent can effectively repair and treat the silt at different heights in the water area, absorb, transform and degrade organic pollutants, and has good economic, social and ecological benefits; at the same time, the inner material pipe 2 uses a vertical plug-in method instead of being buried in the water and soil, which is convenient for timely treatment of the inner material pipe 2 when it is damaged.

[0052] Example 2: Reference Figure 3 、 Figure 7 、 Figure 8 and Figure 9 , a rapid restoration ecological structure for degraded mangroves, based on Example 1, further, a sleeve 7 for covering the second through hole 501 is provided on the outside of the protective tube 5, a counterweight block 701 is rotatably provided at the bottom of the sleeve 7, a movable tube 8 is fixedly provided on the top of the sleeve 7, a telescopic rod 801 is provided between the movable tube 8 and the metal tube 301, and a movable groove 802 is opened on the movable tube 8 to match the metal tube 301.

[0053] Specifically, a sleeve 7 is sleeved on the outside of the protective tube 5, and the bottom of the sleeve 7 is placed on the surface of the silt layer 101 through a counterweight block 701. The counterweight block 701 has a certain weight to prevent the tube body from being displaced under the impact of the water body. The sleeve 7 blocks the tube body portion of the protective tube 5 placed on the surface of the silt layer 101 to avoid the protective tube 5 and the inner material tube 2 from overlapping during the repair work, so that the soil remediation agent also flows out of the through hole of the protective tube 5 placed above the water, resulting in a large amount of soil remediation agent sprayed on the surface of the silt layer 101, causing waste of soil remediation agent. In addition, the sleeve 7 can automatically adjust its height according to the insertion depth of the positioning rod 4 in the water area under the action of the counterweight block 701, and has strong applicability.

[0054] Example 3: Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 A rapid restoration ecological structure for degraded mangroves. Based on Example 2, further, an air guide plate 9 is provided on the top of the movable tube 8, and the bottom of the inner material tube 2 is rotatably connected to the positioning rod 4.

[0055] Furthermore, a bending and moving rod 10 is fixedly provided at the bottom of the inner material tube 2 , and the bending and moving rod 10 moves on the silt layer 101 at the bottom of the water area 1 to be repaired.

[0056] Furthermore, the bending and toggling rod 10 includes an L-shaped connecting rod 12 fixedly connected to the positioning rod 4, and a plurality of movable tubes 121 are sleeved on the L-shaped connecting rod 12. A coil spring is provided between each movable tube 121 and the L-shaped connecting rod 12, and a toggling rod 122 is fixed on the movable tube 121.

[0057] Specifically, an air guide plate 9 is provided on the top of the mobile tube 8. When the air guide plate 9 is blown by the wind, the mobile tube 8 is driven to rotate. The mobile tube 8 drives the material guide tube 3 to rotate through the telescopic rod 801. The material guide tube 3 drives the protective tube 5 and the inner material tube 2 connected thereto to rotate through the connecting tube 3011, thereby automatically adjusting the outflow range of the soil remediation agent of the inner material tube 2, making the soil remediation range of the inner material tube 2 more comprehensive, avoiding the occurrence of repair dead corners, and effectively improving the restoration effect of the mangrove wetland.

[0058] When the inner material tube 2 rotates, the bent and moved lever 10 moves the silt in the silt layer 101, so that gaps and channels appear between the silt layers 101, thereby facilitating the soil remediation agent flowing out of the inner material tube 2 to fully penetrate into the silt layer 101, and can fully absorb, transform and degrade the organic pollutants in the silt layer 101;

[0059] When the bending and toggling rod 10 may encounter plant roots or stones firmly fixed in the soil layer during rotation, the movable tube 121 will stop relative to the rotating L-shaped connecting rod 12 when the toggling rod 122 is subjected to force, and will automatically avoid the stones or plant roots to avoid affecting the normal loosening and through-hole action of the bending and toggling rod 10 as a whole.

[0060] Example 4: Reference Figure 1 A rapid restoration ecological structure for degraded mangroves, based on Example 3, further includes a fence structure 11, which is arranged at the edge of the water area 1 to be restored. The fence structure 11 includes artificial fences and / or ecological fences. The artificial fences include sandbags or mud bags, and the ecological fences are made of wooden piles or oyster shells.

[0061] Specifically, artificial fences or ecological fences are set up around the water area to be restored 1 to intercept garbage around the sea area outside the mangrove area. The multiple fence structures 11 form an ecological barrier to intercept garbage, further repair the ecological structure of the mangroves, ensure the normal growth of plants, purify the mangrove wetlands, and play a role in treating both the symptoms and the root causes.

[0062] Working principle: The staff evenly inserts multiple positioning rods 4 into the silt layer 101 in the water area 1 to be repaired, especially near the mangrove plants, so that multiple inner material tubes 2 are evenly distributed in the water area 1 to be repaired. Two adjacent inner material tubes 2 are connected by the guide tube 3. When the repair work is not in progress, the protective tube 5 blocks the first through hole 201 of the inner material tube 2 to prevent silt and impurities in the water from entering the inner material tube 2, causing blockage of the inner material tube 2 and affecting the subsequent repair and use of the inner material tube 2;

[0063] A casing 7 is sleeved on the outside of the protective tube 5. The bottom of the casing 7 is placed on the surface of the silt layer 101 through a counterweight block 701. The counterweight block 701 has a certain weight to prevent the tube body from being displaced under the impact of the water. The casing 7 blocks the part of the protective tube 5 that is placed on the surface of the silt layer 101.

[0064] When performing the repair work, the water pump 13 is controlled to operate. The water pump 13 extracts the soil repair agent from the soil repair agent box 131 and transports it to the metal pipe 301 through the guide pipe 3. The soil repair agent drives the toggle piece 603 through the guiding effect of the guide block 3012. The toggle piece 603 drives the protective pipe 5 to rotate through the rotating shaft 601, so that the protective pipe 5 rotates relative to the inner pipe 2. The second through hole 501 of the protective pipe 5 is aligned with the first through hole 201 of the inner pipe 2. The soil repair agent in the metal pipe 301 enters the inner pipe 2 through the connecting pipe 3011 and flows out through the through hole. When the outflowing soil repair agent impacts the wetland water body and silt outward to repair the wetland water body and silt, it can also limit external substances from entering the inner pipe 2 through the through hole, thereby ensuring the continuous repair and use of the inner pipe 2. The soil repair agent repairs the soil while providing the mangrove plants with the elements required for growth.

[0065] An air guide plate 9 is provided on the top of the mobile tube 8. When the air guide plate 9 is blown by the wind, it drives the mobile tube 8 to rotate. The mobile tube 8 drives the material guide tube 3 to rotate through the telescopic rod 801. The material guide tube 3 drives the protective tube 5 and the inner material tube 2 connected thereto to rotate through the connecting tube 3011, thereby automatically adjusting the outflow range of the soil remediation agent in the inner material tube 2, making the soil remediation range of the inner material tube 2 more comprehensive and avoiding the occurrence of remediation blind spots.

[0066] When the inner material tube 2 rotates, the bent and moved lever 10 moves the silt in the silt layer 101, so that gaps and channels appear between the silt layers 101, thereby facilitating the soil remediation agent flowing out of the inner material tube 2 to fully penetrate into the silt layer 101, and can fully absorb, transform and degrade the organic pollutants in the silt layer 101;

[0067] When the bending and toggling rod 10 encounters plant roots or stones firmly fixed in the soil layer during rotation, the movable tube 121 is stationary relative to the rotating L-shaped connecting rod 12 when the toggling rod 122 is stressed, and automatically avoids the stones or plant roots, thereby avoiding affecting the normal loosening and through-hole action of the bending and toggling rod 10 as a whole;

[0068] The present invention facilitates the uniform delivery of the soil remediation agent into the silt layer 101 through a plurality of inner material pipes 2, so that the soil remediation agent can effectively repair and treat the silt at different heights in the water area, absorb, transform and degrade organic pollutants, and has good economic, social and ecological benefits; at the same time, the inner material pipe 2 uses a vertical plug-in method instead of being buried in the water and soil, which is convenient for timely treatment of the inner material pipe 2 when it is damaged.

[0069] 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.
