Description

Technical Field

[0001] The invention belongs to the technical field of sewage purification equipment, and specifically relates to a river ecological restoration device and method. Background Art

[0002] With the increasing severity of environmental pollution, the problem of eutrophication of river water bodies has become increasingly prominent, leading to deterioration of water quality and serious damage to aquatic ecosystems. Therefore, it is particularly important to restore the river ecology.

[0003] In the field of river aquatic ecosystem restoration, the introduction of ecological floating islands can increase the proportion of plants in the river ecosystem, and absorb nutrients such as nitrogen and phosphorus in the water through the growth and reproduction of plants, reducing the eutrophication of water bodies. At the same time, microorganisms attached to plant roots can also degrade pollutants in the water, thereby effectively purifying the water quality. In addition, ecological floating islands can provide habitats and breeding places for birds and fish, causing the river ecosystem to tend to be balanced and stable. Therefore, ecological floating islands are widely used in the field of river ecological restoration, especially in the field of still water. The ecological floating island has a more obvious effect on water purification. However, since the water flow in the still water of the river tends to be stable, the position of the ecological floating island on the water surface is relatively fixed, which affects the efficiency of the ecological floating island in purifying the water.

[0004] In order to improve the water restoration effect of ecological floating islands in still water, the related art discloses a scheme with application number CN2023110915241 and name of ecological floating island system for water body cruising. In this scheme, a controller controls the ecological floating island to drive the ecological floating island to undergo aeration treatment in the water body through aeration, and utilizes the impact force generated by aeration to cause the ecological floating island to move in the water body, thereby expanding the influence range of the ecological floating island. However, it is found in actual application that, on the one hand, due to the high energy consumption of the ecological floating island during forced aeration cruising, it is not suitable for batch application. On the other hand, when the movement rate of the ecological floating island is too fast, not only will the time for plants and microorganisms on the roots to transform and absorb nutrients in the water body be too short, but also the microbial film attached to the roots of the plants on the ecological floating island will be shed in large quantities, thereby having a negative impact on the water purification effect of the ecological floating island.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7 As shown, a river ecological restoration device and method described in the present invention includes a floating island body 1, on which a planting trough 11 is provided, and also includes a micro-power drive mechanism, which is installed on the floating island body 1. The micro-power drive mechanism is used to drive the floating island body 1 to move, and the micro-power drive mechanism includes: a decomposition and gas production chamber 12, an injection pipe 2 and a booster plate 21. The floating island body 1 is provided with a decomposition and gas production chamber 12, and the decomposition and gas production chamber 12 is filled with decomposition and gas production raw materials. The injection pipe 2 is installed on the floating island body 1, and one end of the injection pipe 2 is conductively connected to the top of the decomposition and gas production chamber 12, and the other end is inclined toward the water surface. A booster plate 21 is sealed and slidably installed in the decomposition and gas production chamber 12, and the top of the booster plate 21 is elastically installed in the decomposition and gas production chamber 12 through a support spring 27. A solar heating plate is fixedly installed on the floating island body 1 through an insulation rod.

[0023] A cleaning groove 6 is formed on the pressurizing plate 21 , and a baffle 61 is detachably and hermetically installed in the cleaning groove 6 .

[0024] In the field of river aquatic ecosystem restoration, the ecological floating island method is one of the most frequently used and widely used measures. However, in some areas of rivers, pools and ponds where the water flow is poor or even almost stagnant, the ecological floating island lacks the power to move, which will lead to the fixation of the purification area of ​​the ecological floating island, resulting in the inability to maximize the purification effect of the ecological floating island. In order to improve this phenomenon, the present invention improves the ecological floating island and controls the slow and continuous movement of the ecological floating island, thereby expanding the influence range of the ecological floating island.

[0025] Specifically, when the floating island body 1 is placed on the river surface, the ecological floating island is suspended on the river surface under the action of buoyancy. Under the nourishment of the river water, the plants in the planting grooves 11 on the floating island body 1 continue to grow and reproduce, and extend their roots into the river water, providing a place for microorganisms to attach. During the long-term floating process, the water body is purified. In this process, the micro-power drive mechanism set on the floating island body 1 drives the floating island body 1 to move slowly on the river surface. By switching the position, the purification range of the floating island body 1 is increased. The micro-power drive mechanism in the present invention uses the decomposition and gas production of the decomposition gas production raw material as the power source. During use, the river maintenance personnel periodically replenish the decomposition gas production raw material into the decomposition gas production chamber 12. As time goes by, the gas content in the decomposition and gas production chamber 12 gradually increases. Under the action of air pressure, the booster plate 21 is pushed upward, causing the support spring 27 to be continuously compressed. When the booster plate 21 moves to the opening position of the injection pipe 2, the injection pipe 2 is connected to the decomposition and gas production chamber 12. At this time, under the action of air pressure, the airflow is sprayed onto the water surface along the injection pipe 2. Under the action of the injection force of the airflow and the reaction force generated when the airflow is sprayed, the floating island body 1 has a tendency to move away from the gas injection direction. With the movement of the floating island body 1, the position of the floating island body 1 in the river channel changes, thereby changing the position of the ecological floating island, thereby improving the restoration effect of the ecological floating island on the river channel aquatic ecosystem.

[0026] It should be noted that the decomposition gas-producing raw material generated in the present invention is preferably a mixture of EM bacteria, dead branches and leaves, and water. When the mixture is put into the decomposition gas-producing chamber 12, under the decomposition action of the bacteria, the organic matter in the dead branches and leaves will be continuously decomposed into carbon dioxide, water, etc. Therefore, when the airflow is sprayed, the eruption of the airflow will cause the carbon dioxide concentration around the floating island body 1 to increase to a certain extent, thereby promoting the photosynthesis of the plants in the planting trough 11.

[0027] At the same time, in other embodiments of the present invention, a solar heating panel is also installed on the floating island body 1, and the solar heating panel is connected to the decomposition and gas production chamber 12 through a heat conduction material. Therefore, during the long-term use of the ecological floating island, as the light intensity gradually increases, the solar heating panel can provide heat energy supplement for the decomposition and gas production chamber 12, and the increase in temperature will not only cause the gas expansion rate to accelerate, but also cause the organic matter to be decomposed faster, thereby accelerating the rate of increase of the air pressure in the decomposition and gas production chamber 12, which is convenient for accelerating the movement rate of the ecological floating island in weather with good lighting environment. Therefore, in weather with good lighting environment, not only the transpiration of plants is significantly enhanced, but also the appropriately increased temperature and the supplement of carbon dioxide can also enhance the photosynthesis of plants, thereby enhancing the purification effect of the ecological floating island.

[0028] The present invention sets a micro-power drive mechanism and utilizes the continuous decomposition and gas production of the decomposition gas-producing raw materials to cause the air pressure in the decomposition gas-producing chamber 12 to continue to increase. When the air pressure intensity reaches a preset value, the booster plate 21 moves upward under the action of the air pressure, causing the injection pipe 2 to be connected to the decomposition gas-producing chamber 12, and the high-pressure airflow is ejected outward. Under the action of the reaction force, the mobility of the ecological floating island is enhanced, thereby enhancing the purification effect of the ecological floating island in still water.

[0029] As a preferred embodiment of the present invention, a lifting groove 22 is opened in the decomposition gas production groove, and a lifting block 23 is elastically installed in the lifting groove 22 through a reset spring 26. The booster plate 21 is inlaid with an elastic friction block 24 on the side facing the lifting groove 22, and the injection pipe 2 is installed on the lifting block 23.

[0030] The decomposition and gas production chamber 12 and the injection pipe 2 are both provided in plural numbers, and the plurality of decomposition and gas production chambers 12 and the injection pipes 2 are evenly arranged along the circumferential direction of the floating island body 1 .

[0031] In order to enhance the airflow impact effect, the injection pipe 2 in the present invention is made of a bellows, and a lifting groove 22 is provided in the decomposition gas production groove. One end of the injection pipe 2 is fixedly mounted on a lifting block 23 in the lifting groove 22 and passes through the lifting block 23. In the process of continuous gas generation by the decomposition gas production raw material in the decomposition gas production chamber 12, the air pressure pushes the boost plate 21 to move upward until the boost plate 21 rises to the end of the decomposition gas production chamber 12, so that the opening of the injection pipe 2 is connected with the high-pressure gas. In this process, since the lifting block 23 is initially located at the top of the lifting groove 22, as the boost plate 21 continues to rise, the elastic friction block 24 embedded and installed on the boost plate 21 always blocks the lifting groove 22. When the elastic friction block 24 contacts the bottom of the lifting block 23, under the action of air pressure, the boost plate 21 rises, causing the elastic friction block 24 to compress and deform until the injection pipe 2 is connected with the high-pressure gas. At this time, the high-pressure gas flows through the conducting pipe and is sprayed on the water surface. The reaction force is used to drive the floating island body 1 to float on the water surface. As the high-pressure gas in the decomposition and gas production chamber 12 continues to flow out, when the outflow rate is greater than the gas generation rate, the gas pressure in the decomposition and gas production chamber 12 decreases. At this time, under the elastic action of the support spring 27, the booster plate 21 will move downward. Under the action of the deformed elastic friction block 24, when the booster plate 21 moves downward, it will drive the lifting block 23 to move downward synchronously, thereby continuously discharging the gas in the decomposition and gas production chamber 12, thereby enhancing the driving effect of the airflow injection. As the descending distance increases, the pulling force of the reset spring 26 at the top of the lifting groove 22 gradually increases, and finally the lifting block 23 breaks away from the restriction of the elastic friction block 24 and resets upward. The elastic friction block 24, under its own elastic action, seals the lifting groove 22 again, and then in each gas injection process, the airflow injection intensity can be enhanced, so that the movement distance of the floating island body 1 is increased.

[0032] The arrangement of multiple decomposition and gas production chambers 12 and injection pipes 2 means that when the ecological floating island is used for a long time, when gas is generated in the decomposition and gas production chamber 12, the pressure increase rate in the multiple decomposition and gas production chambers 12 will be different due to the differences in temperature, light intensity, raw material filling time and other factors. In addition, since the ecological floating island is on the river channel for a long time, it is affected by various environmental factors such as water flow impact and wind impact, and its position and orientation are relatively unstable. Therefore, the arrangement of multiple injection pipes 2 and decomposition and gas production chambers 12 not only increases the movement frequency of the ecological floating island, but also increases the uncertainty of its movement direction, thereby increasing the complexity of the movement trajectory of the ecological floating island and increasing the coverage of the river surface by the movement trajectory of the ecological floating island.

[0033] The floating island body 1 is provided with an impact channel 25 which is evenly arranged along the circumference of the floating island body 1 and extends toward the center of the planting trough 11 . The injection pipes 2 are located at one end of the impact channel 25 close to the center of the planting trough 11 .

[0034] When EM bacteria and dead branches and leaves are used as the decomposition gas-producing raw materials, the gas produced by their decomposition is carbon dioxide. In order to enhance the impact on the carbon dioxide concentration around the plants, an impact flow channel 25 is provided in the present invention. The impact flow channel 25 extends toward the center of the planting trough 11, and the installation positions of multiple conducting pipes are close to the center of the planting trough 11. Therefore, when the airflow impacts the water surface and diffuses to the surroundings under the action of the reaction force, the characteristic that the injection position is relatively close to the center of the planting trough 11 can be utilized to make the diffused carbon dioxide approach the plants. It should be noted that although the ecological floating island will move when the airflow is injected, thereby gradually changing the position of the ecological floating island, after the carbon dioxide is injected on the water surface, it diffuses under the action of the reaction force. When the ecological floating island moves, the plants in the planting trough 11 move, which will promote the movement of carbon dioxide diffused into the air. By utilizing the interception effect of the plants, carbon dioxide can be intercepted and retained to a certain extent, thereby providing a certain boost to the photosynthesis of the plants.

[0035] As a preferred embodiment of the present invention, a collecting bucket 3 is installed on the outside of the floating island body 1. The collecting bucket 3 is made of a mesh plate. The collecting bucket 3 extends obliquely to below the liquid surface away from one end of the floating island body 1. A guide mesh plate 31 is fixedly installed on the floating island body 1. The guide mesh plates 31 are distributed on both sides of the collecting bucket 3. The guide mesh plates 31 are used to increase the collection efficiency of the collecting bucket 3.

[0036] The collecting bucket 3 is hingedly mounted to the floating island body 1 , a transmission rod 32 is fixedly mounted on the booster plate 21 , a connecting rod 33 is fixedly mounted on the collecting bucket 3 , the connecting rod 33 is elastically connected to the transmission rod 32 via an elastic rope 34 , and the connecting rod 33 is located on the ascending path of the transmission rod 32 .

[0037] When the floating island body 1 moves due to the impact of airflow, the collecting bucket 3 and the guide mesh plate 31 installed on the outside of the floating island body 1 generate relative movement with the duckweed, fallen leaves, etc. on the water surface, and finally the duckweed and fallen leaves enter the collecting bucket 3. At the same time, due to the continuous increase of air pressure in the decomposition and gas production chamber 12, the booster plate 21 pushes the transmission rod 32 to move upward. When the transmission rod 32 rises, it directly pushes the connecting rod 33 to rise, thereby causing the collecting bucket 3 to deflect below the river surface. When the gas in the decomposition and gas production chamber 12 is released, the booster plate 21 and the transmission rod 32 drop rapidly. Under the pull of the elastic rope 34, the connecting rod 33 deflects downward, thereby causing the collecting bucket 3 to deflect upward. The water flow in the collecting bucket 3 is discharged, while the solid branches and duckweed are intercepted. As the deflection angle of the collecting bucket 3 gradually increases, the branches, leaves and duckweed slide along the collecting bucket 3 toward the floating island body 1. It should be noted that in actual application, in order to facilitate the branches, leaves and duckweed in the collecting bucket 3 to slide toward the floating island body 1, at the initial stage of design, an inclined surface is set on the side of the collecting bucket 3 close to the floating island body 1, and the rotation of the collecting bucket 3 increases the difficulty of falling of dead branches and leaves. In order to enhance the collection effect of the collecting bucket 3, the injection pipe 2 in the present invention is away from the corresponding decomposition and gas production cavity 12 and extends to the impact flow channel 25 on the opposite side. The airflow injection direction is away from the corresponding decomposition and gas production cavity 12. Therefore, the movement direction of the floating island body 1 is consistent with the position of the decomposition and gas production cavity 12 that releases the airflow, thereby enhancing the collection effect of the collecting bucket 3.

[0038] The floating island body 1 is provided with a plurality of storage slots 4, which are conductively connected to the decomposition gas production chamber 12, and a closing plate 41 is hingedly installed in the storage slot 4, and a closing spring 42 is fixedly installed on the inner wall of the storage slot 4. In the initial state, the closing plate 41 closes the storage slot 4 under the action of the closing spring 42.

[0039] When the collecting bucket 3 is deflected, causing the collected branches and leaves to slide down under the action of gravity, the storage slot 4 opened on the floating island body 1 is located at the end of the branch and leaf sliding path, and the branches and leaves are stored. As the weight of the branches and leaves in the storage slot 4 gradually increases, the closing plate 41 will compress the closing spring 42, so that the branches and leaves are replenished into the decomposition gas production chamber 12 to replenish the decomposition gas production raw materials.

[0040] As a preferred embodiment of the present invention, a medicine storage box 5 is installed on the booster plate 21, and EM bacterial liquid is stored in the medicine storage box 5. A dosing tube 51 is fixedly installed on the medicine storage box 5, and a pressing bag 52 is fixedly installed on the bottom end of the dosing tube 51. A one-way liquid inlet hole 53 and a one-way liquid outlet hole 54 are opened on the dosing tube 51. The one-way liquid inlet hole 53 is conductively connected to the inner cavity of the medicine storage box 5, and the one-way liquid outlet hole 54 is conductively connected to the decomposition gas production cavity 12.

[0041] During the lifting and lowering process of the booster plate 21, when the booster plate 21 rises toward the top of the decomposition and gas production chamber 12, the medicine storage box 5 and the dosing tube 51 installed above the booster plate 21 gradually approach the top of the decomposition and gas production chamber 12, thereby squeezing the pressing bag 52 at the top of the dosing tube 51. When the pressing bag 52 is in a squeezed state, the pressure in the dosing tube 51 increases, thereby causing the EM bacteria liquid in the dosing tube 51 to drip onto the bottom of the decomposition and gas production groove. When the booster plate 21 descends, the pressing bag 52 recovers under the action of its own elasticity, thereby causing negative pressure in the dosing tube 51. Under the action of negative pressure, the EM bacteria liquid in the medicine storage box 5 enters the dosing tube 51 through the one-way liquid inlet hole 53, which is convenient for the next dripping of EM bacteria liquid. Through continuous replenishment of branches and leaves and bacteria liquid, the decomposition and gas production of organic matter in the decomposition and gas production chamber 12 continues.

[0042] After each cycle, the staff replenishes the EM bacterial solution in the medicine storage box 5, checks the residual organic matter in the decomposition gas storage chamber, and cleans the organic matter residue after decomposition and gas production. The cleaned organic matter residue can not only be used as fertilizer, but also can be backfilled into the planting trough 11 to provide support for plant growth.

[0043] like Figure 8 As shown, a river ecological restoration method comprises the following steps: S1: Mixing fermented fertilizer with soil, filling the mixture into the planting trough 11, and evenly planting aquatic plants in the planting trough 11; S2: Open the baffle 61 in the cleaning tank 6, pour the decomposition gas production raw materials into the decomposition gas production chamber 12, and replenish the EM bacteria liquid in the medicine storage box 5, and then reset the baffle 61; S3: The floating island body 1 is suspended on the water surface for a long time, and the plant roots extend into the river water to purify the water quality, while the decomposition and gas production chamber 12 continues to decompose and produce gas; S4: As the gas pressure in the decomposition gas production chamber 12 continues to increase, the booster plate 21 is pushed upward. When the booster plate 21 passes over the opening of the injection pipe 2, the air flow flows through the injection pipe 2 and is injected onto the water surface in the impact flow channel 25; S5: Under the action of impact and reaction force, the floating island body 1 moves slightly. During long-term use, combined with the flow of water and wind, the floating island body 1 purifies the water quality of the river.
