Abstract
Description
Technical Field
[0001] The present application relates to the field of ecological ditches, and in particular to an ecological ditch comprising permeable bricks. Background Art
[0002] Ecological ditches refer to farmland ditch ecosystems with a certain width and depth, composed of water, soil and organisms, with their own unique structure and corresponding ecological functions. They are also often called farmland ditch wetland ecosystems. As a farmland wetland ecosystem, ecological ditches not only assume the functions of traditional drainage ditches, but also effectively reduce the content of nutrients such as nitrogen and phosphorus flowing into surface water through natural processes such as soil adsorption, plant absorption and microbial degradation, thereby alleviating the eutrophication of water bodies.
[0003] In order to enhance the self-purification capacity of water bodies and improve water quality, ecological ditches often use floating islands to plant aquatic plants on the floating islands. The roots of the plants absorb nutrients such as nitrogen and phosphorus in the water, reduce eutrophication of the water body, and provide attachment points for microorganisms to promote the decomposition of organic matter. In addition, floating islands can also provide biological habitats, increase biodiversity, beautify the environment, reduce water evaporation, and have strong adaptability and are suitable for various water environments.
[0004] However, the use of floating islands may also bring some problems. Due to the effect of water flow, some floating pollutants tend to accumulate in front of the floating islands, which will not only affect the contact between the roots of floating island plants and the water body, reducing their purification efficiency, but may also cause water flow obstruction, change the path and speed of water flow, and increase the risk of flooding. Accumulated pollutants may also damage the beauty of the environment, affect the landscape value of ecological ditches, and even have a toxic effect on plants and aquatic organisms on the floating islands, interfering with the normal operation of the ecosystem. Summary of the invention
[0005] In order to optimize the design of the floating island to ensure its long-term effective operation, reduce the impact of floating pollutants on it, and effectively ensure the floating island's ability to purify water, the present application provides an ecological ditch comprising permeable bricks.
[0006] The present application provides an ecological ditch comprising permeable bricks, which adopts the following technical solution: An ecological ditch including permeable bricks comprises a main channel body and a floating island, wherein the main channel body comprises: a first channel body section; a second channel body section, which is wider than the first channel body section, the second channel body section forms flow-gathering parts on both sides protruding from the first channel body section, the floating island is located in the middle of the second channel body section, and each flow-gathering part forms a water inlet and a water outlet respectively along the direction of water flow; a blocking net vertically arranged on the two flow-gathering parts along the extension direction of the main channel body, the blocking net partially protrudes from the water surface, and the rear side of the blocking net blocks the outlet of the flow-gathering part; a guide floating plate fixed to a side of the floating island facing the water flow direction along the width direction of the main channel body, the guide floating plate is at least partially located above the water surface, and the middle part of the guide floating plate is protruding away from the floating island, so that the two ends of the guide floating plate are symmetrically inclined along the direction of water flow and extend to the blocking nets of the two flow-gathering parts.
[0007] By adopting the above technical solution, the guide float on the front side of the floating island can effectively disperse the water flow entering the ditch under the action of the water flow, avoiding the water flow from directly impacting the floating island, thereby reducing the accumulation of pollutants in front of the floating island and improving the purification efficiency of the floating island. The pollutants will enter the flow-gathering part under the guidance of the guide float, and the design of the barrier net can effectively block large particles of pollutants, gather pollutants for easy salvage, and prevent them from continuing to flow into the rear water flow through the outlet of the floating island, further protecting the ecological environment of the subsequent ditch, keeping the ditch unobstructed, and reducing the risk of flooding.
[0008] Optionally, it also includes: two columns, each of which is vertically fixed to the flow-gathering parts and arranged along the extension direction of the main channel body, the upper end of each column extending out of the water surface and bending away from the middle of the width of the main channel body to form a curved section; guide columns, respectively fixed to one end of each column located underwater, and bending away from the middle of the width of the main channel body to fit the outer wall of the main channel body and continue to extend upward to the water surface; bottom sleeves, which are sleeved on the columns and the guide columns and slide down to the bottom of the guide columns; floating sleeves, which are sleeved on the columns and the guide columns and float above the water surface, the upper ends of both sides of the barrier net are respectively fixed to the floating sleeves, and the lower ends of both sides of the barrier net are respectively fixed to the bottom sleeves.
[0009] By adopting the above technical solution, the design of the column and the guide column can effectively support and position the barrier net to ensure its stability and reliability. The curved design of the column enables the barrier net to better adapt to the changes in water flow and prevent displacement or damage caused by water flow scouring. The combined use of the floating sleeve and the sinking sleeve can not only adjust the height of the barrier net so that it is always in the best position, but also effectively intercept and collect floating pollutants, reduce the impact of pollutants on the roots of floating island plants, and improve the water purification efficiency. In addition, when it is necessary to clean the dirt in the flow-gathering part, by dragging the sinking sleeve upward along the guide column, the lower end of the sinking sleeve can be moved out of the water surface. At this time, by moving the floating sleeve and making it slide along the curved part of the column, the barrier net can be tilted as a whole, so as to quickly dump the blocked dirt to the shore as a whole, and when the barrier net needs to be replaced, the old barrier net can be removed from the sinking sleeve and the floating sleeve and replaced with a new one.
[0010] Optionally, it also includes: a first chain, one end of which extends underwater and is fixed to the bottom sleeve, and the other end extends out of the water; a second chain, one end of which is fixed to the floating sleeve, and the other end extends along the curved section of the column.
[0011] By adopting the above technical solution, one end of the second chain is fixed to the floating sleeve, and the other end extends along the curved section of the column. On the one hand, when the water flow is too large, the first chain and the second chain can be fixed on the shore respectively, thereby ensuring the stability of the barrier net under the impact of the water flow and preventing the barrier net from being washed away or displaced, thereby effectively intercepting floating pollutants and avoiding their accumulation in front of the floating island, reducing the impact on the roots of plants on the floating island, and improving the water purification efficiency. At the same time, it ensures the smooth flow of water and reduces the risk of flooding. On the other hand, when it is necessary to salvage the waste, by dragging the first chain, the bottom sleeve can be dragged out of the water from the underwater guide column, thereby dragging the lower end of the barrier net out of the water. At the same time, by pulling the second chain, the upper end of the barrier net can be separated from the water surface and lifted up to facilitate the dumping and cleaning of the waste.
[0012] Optionally, revetments are provided on both sides of the main channel body; the revetments of the second channel body section are paved with permeable bricks and gravel layers from top to bottom, and guide water pipes are laid in the gravel layers to guide water into the main channel body.
[0013] By adopting the above technical solution, the revetment of the second channel section is paved with permeable bricks and gravel layers from top to bottom, and the gravel layers are all paved with guide water pipes. On the one hand, this design is that when the barrier net is dragged to the water surface and positioned behind the revetment, the water dragged by the barrier net can penetrate into the gravel layer through the permeable bricks, and then be evenly guided into the ditch through the guide water pipes, reducing the accumulation of water on the revetment. At the same time, when rainwater falls on the revetment, it can also quickly guide the rainwater out, making up for the problem of missing slope diversion in this part, avoiding soil erosion caused by excessive rainwater runoff, and enhancing the water resource management capacity of the ecological ditch. In addition, the setting of permeable bricks and gravel layers helps to filter impurities and pollutants in rainwater, further improve water quality, and reduce the impact on the ecological environment.
[0014] Optionally, it also includes: a bottom net, fixed to the lower side of the guide float; and a pendant, fixed to the lower side of the bottom net and located at the bottom of the water.
[0015] By adopting the above technical solution, the bottom net is fixed to the lower side of the guide float, which increases the stability of the floating island and prevents the floating island from being displaced due to the impact of water flow. The pendants are fixed to the lower side of the bottom net and located on the bottom of the water, which further enhances the stability of the floating island and ensures the stability of the position of the floating island under the action of water flow, thereby increasing the contact area between the roots of the floating island plants and the water body and improving the water purification efficiency. At the same time, the pendants help reduce the accumulation of pollutants on the front and rear sides of the floating island, avoid water flow obstruction, maintain normal water flow path and speed, and reduce flood risks.
[0016] Optionally, the bottom of the main channel body is paved with permeable bricks and gravel layers from top to bottom, and a one-way water pipe is buried in the gravel layer; water storage wells are also provided on both sides of the main channel body, and the one-way water pipes are connected to the water storage wells to allow water to flow into the water storage wells.
[0017] By adopting the above technical solution, permeable bricks and gravel layers are laid at the bottom of the ditch, which can effectively improve the permeability of the water body, speed up the flow of water, and prevent the accumulation of pollution caused by water retention. The setting of a one-way water pipe further ensures the directional transportation of water flow and avoids secondary pollution caused by backflow. The introduction of water storage wells not only increases the water storage capacity, but also can quickly collect rainwater in the rainy season, reduce the probability of floods and waterlogging, and provide water supplements in the dry season to ensure the continuous operation of the ecological ditch.
[0018] Optionally, it also includes: slopes formed on both sides of the first channel section, and the slopes are paved with permeable bricks and gravel layers from top to bottom.
[0019] By adopting the above technical solution, permeable bricks and gravel layers are laid on the slope from top to bottom, which enhances the stability and permeability of the slope, helps rainwater to quickly penetrate into the ground, reduces surface runoff, prevents soil erosion, and at the same time increases the groundwater level and improves the surrounding ecological environment.
[0020] Optionally, it also includes: a planting area, which is arranged on the slope and is in the shape of a regular triangle.
[0021] By adopting the above technical solution, the planting area set up on the slope can effectively increase the vegetation coverage area, improve soil stability, and prevent soil erosion. At the same time, the planting area in the shape of a regular triangle can optimize space utilization, increase plant density, enhance the purification capacity of ecological ditches, further reduce the content of nutrients such as nitrogen and phosphorus in the water body, and reduce eutrophication of water bodies.
[0022] Optionally, it further includes: a plurality of water diversion plates arranged along the two outer sides of the slope corresponding to the inclined planting area, and the length direction of the water diversion plates is arranged along the extension direction of the main channel body.
[0023] By adopting the above technical solution, the water diversion plates are arranged along the two outer sides of the slope corresponding to the inclined planting area, and the length direction of the water diversion plates is set along the extension direction of the main channel body, so that the water flow can be more evenly distributed under the action of the water diversion plates, reducing the scouring of the slope by the water flow and protecting the stability of the slope.
[0024] Optionally, it also includes: a fixed rod, the lower end of which is fixed to the slope, and the water diversion plate is connected to the upper end of the water diversion plate; a torsion spring fixed between the fixed rod and the water diversion plate, which normally restricts the water diversion plate to remain arranged along the length direction of the main channel body. When the water diversion plate is impacted on the side away from the planting area, the side of the water diversion plate away from the planting area can tilt and swing toward the direction of the main channel body, so that adjacent water diversion plates are connected to form an inclined drainage surface.
[0025] By adopting the above technical solution, the torsion spring is fixed between the fixed rod and the water diversion plate, which can ensure that the water diversion plate is stably arranged along the length direction of the main channel body under normal conditions to ensure normal water flow guidance. When the water flow is too large, since the water diversion plate can only rotate in one direction, when the side away from the planting area is impacted, the water diversion plate can respond quickly and tilt toward the main channel body, thereby connecting with other water diversion plates to form an inclined drainage surface, effectively dispersing the water flow pressure, preventing the water flow from directly scouring the planting area, protecting the plants in the planting area from damage, reducing soil erosion, and improving the stability of the entire ecological ditch.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up a flow-collecting section and a barrier net in the second channel section, floating pollutants are effectively prevented from accumulating in front of the floating island, reducing the impact on the roots of plants on the floating island and improving the purification efficiency of the floating island; 2. The design of the guide float makes the water flow smoother and avoids water flow obstruction, thereby reducing the changes in water flow path and speed and reducing flood risks; 3. The combined design of the barrier net and the guide float not only beautifies the environment, but also protects the landscape value of the ecological ditch and avoids the damage to the beauty of the environment caused by accumulated pollutants.

[0035] The following will be combined with the attached Figure 1-7, the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.
[0036] The inventors of the present application found that when the ecological ditch uses the floating island 2, due to the effect of water flow, some floating pollutants tend to accumulate on the front side of the floating island 2, which will not only affect the contact between the plant roots of the floating island 2 and the water body, reducing its purification efficiency, but may also cause water flow obstruction, change the water flow path and speed, and increase the risk of flooding.
[0037] To this end, the present application mainly adopts the following technical solutions: an ecological ditch including permeable bricks 32, including a main channel body 1 and a floating island 2, the main channel body 1 including a first channel body section 11 and a second channel body section 12, the width of the second channel body section 12 is greater than that of the first channel body section 11, the second channel body section 12 forms a flow collecting portion 13 on both sides protruding from the first channel body section 11, the floating island 2 is located in the middle of the second channel body section 12, and each flow collecting portion 13 forms a water inlet and a water outlet 132 respectively along the water flow direction; a blocking net 75 is vertically arranged at the two flow-gathering parts 13 along the extension direction of the main channel body 1, the blocking part protrudes from the water surface, and the rear side of the blocking net 75 blocks the outlet 132 of the flow-gathering part 13; the guide floating plate 21 is fixed to the side of the floating island 2 facing the water flow direction along the width direction of the main channel body 1, the guide floating plate 21 is at least partially located above the water surface, and the middle part of the guide floating plate 21 is protruded away from the floating island 2, so that the two ends of the guide floating plate 21 are symmetrically inclined along the water flow direction and extend to the blocking net 75 of the two flow-gathering parts 13. Through this technical solution, the accumulation of pollutants on the front side of the floating island 2 is reduced, the purification efficiency of the floating island 2 is improved, the ditch is kept unobstructed, and the risk of flooding is reduced. The following is a further detailed description of this application. Example
[0038] Reference Figure 1 and Figure 2 An embodiment of the present application provides an ecological ditch including permeable bricks 32 , including a main channel body 1 and a floating island 2 located in the main channel body 1 .
[0039] The main channel body 1 can be divided into a first channel body section 11 and a second channel body section 12 arranged at intervals along its extension direction, wherein the width of the second channel body section 12 is greater than that of the first channel body section 11, and the parts of the second channel body section 12 protruding from the first channel body section 11 on both sides form a flow-gathering portion 13, and the flow-gathering portion 13 is rectangular in top-down view, and in some other embodiments, a trapezoidal shape can also be used. The floating island 2 is located in the middle of the second channel body section 12. And the two sides of the floating island 2 and the flow-gathering portion 13 form a water inlet 131 and a water outlet 132 respectively along the water flow direction, that is, the upper water flow in the first channel body section 11 enters the flow-gathering portion 13 through the water inlet 131, and flows out of the flow-gathering portion 13 through the water outlet 132. The lower side of the floating island 2 is fixed to the bottom of the main channel 1 by ropes to ensure that the floating island 2 will not drift with the water flow. Different aquatic plants are planted on the upper side of the floating island 2 according to needs to absorb nutrients such as nitrogen and phosphorus in the water through their roots, thereby reducing eutrophication of the water body and providing attachment points for microorganisms to promote the decomposition of organic matter.
[0040] The bottom of the main channel 1 is paved with a gravel layer 3, a fine sand layer and a permeable brick 32 from bottom to top, so as to enhance the permeability and self-purification ability of the main channel 1, reduce surface runoff and improve groundwater recharge. Reference Figure 2 and Figure 3 The first channel body section 11 is also formed with side slopes 4 on both sides, and the side slope 4 is also padded with gravel layer 3 and then permeable bricks 32 are laid on its surface. At the same time, a planting area 41 is reserved on the side slope 4 for planting green plants.
[0041] Reference Figure 3 and Figure 4 In the present embodiment, a planting area 41 in the shape of an equilateral triangle is used for planting green plants. Furthermore, water diversion components 42 are arranged at the two hypotenuse positions of the planting area 41, that is, a water diversion component 42 is provided at both ends of each row of green plants in the planting area 41, and a water diversion component 42 is also provided at the uppermost position of the planting area 41. The plurality of water diversion components 42 surround the planting area 41.
[0042] Specifically, the water diversion member 42 includes a fixed rod 421 fixed in the slope 4, a water diversion plate 422 rotatably connected to the upper side of the fixed rod 421, and a torsion spring fixed between the water diversion plate 422 and the fixed rod 421. Under normal circumstances, the torsion spring keeps the length direction of the water diversion plate 422 set along the length direction of the main channel body 1, and when the outer side of the water diversion plate 422, that is, the side of the water diversion plate 422 away from the planting area 41 is impacted, the water diversion plate 422 can squeeze the torsion spring so that the outer side of the water diversion plate 422 is rotated downward to an inclined state. At this time, adjacent water diversion plates 422 are connected end to end to form a drainage surface. It should be noted that in this solution, the water diversion plate 422 located at the uppermost side is fixed to the fixed rod 421, that is, the water diversion plate 422 will not deflect. However, in other embodiments of the present application, water-guiding members 42 that overlap each other on the inner sides of two water-dividing plates 422 may be provided in the uppermost planting area 41. In this case, the water-dividing plates 422 located at the two uppermost water-dividing members 42 can also be tilted and swung to guide the water flow.
[0043] In this arrangement, under normal conditions, the torsion spring is fixed between the fixed rod 421 and the water diversion plate 422, which can ensure that the water diversion plate 422 is stably arranged along the length direction of the main channel body 1 under normal conditions, ensuring normal water flow guidance, so that the water flow can be more evenly distributed under the action of the water diversion plate 422, reducing the scouring of the slope 4 by the water flow, and protecting the stability of the slope 4. When the water flow is too large, since the water diversion plate 422 can only rotate in one direction, when the side away from the planting area 41 is impacted, the water diversion plate 422 can respond quickly and tilt toward the main channel body 1 to swing, thereby connecting with other water diversion plates 422 to form an inclined drainage surface, effectively dispersing the water flow pressure, preventing the water flow from directly scouring the planting area 41, protecting the plants in the planting area 41 from damage, reducing soil erosion, and improving the stability of the entire ecological main channel body 1.
[0044] Replay Figure 1 Furthermore, water storage wells 5 can be set under the banks on both sides of the main channel body 1, and a one-way water pipe 51 can be buried in the gravel layer 3 of the main channel body 1. The one-way water pipe 51 is connected to the water storage well 5 so that the water flow in the main channel body 1 can enter the water storage well 5. A water supply pipe and a valve for controlling the water supply pipe (not shown in the figure) are set in the upper and middle parts of the water storage well 5, and the water supply pipe extends to the planting area 41 in the slope 4. In this way, the setting of the one-way water pipe 51 further ensures the directional transportation of water flow and avoids secondary pollution caused by backflow. The introduction of the water storage well 5 not only increases the water storage capacity, but also can quickly collect rainwater in the rainy season to reduce the probability of flood disasters. At the same time, the arid area can provide water source supplement for the planting area 41 in the dry season by connecting a water pump to the water supply pipe to ensure the continuous operation of the ecological main channel body 1.
[0045] A guide float 21 is vertically fixed to the front side of the floating island 2, that is, the water-facing surface of the floating island 2. The guide float 21 is arranged along the width direction of the main channel body 1 as a whole, and the middle part of the width direction of the guide float 21 protrudes away from the floating island 2 to form a front end against the direction of the water flow, so that both ends of the guide float 21 extend symmetrically and obliquely to the flow-gathering part 13. In other embodiments of the present application, the guide float 21 can also be set as an arc panel. Furthermore, the lower side of the guide float 21 should be at least lower than the lower side of the floating island 2, and the side of the guide float 21 is higher than the water surface. A bottom net 22 is fixed to the lower side of the guide float 21, and a pendant 23 is fixed to the lower end of the bottom plate, and the pendant 23 falls on the bottom surface of the main channel body 1.
[0046] The guide float 21 on the front side of the floating island 2 can effectively disperse the water flow entering the main channel body 1 under the action of the water flow, avoiding the water flow from directly impacting the floating island 2, thereby reducing the accumulation of pollutants in front of the floating island 2 and improving the purification efficiency of the floating island 2. The pollutants will enter the gathering part 13 under the guidance of the guide float 21, and the design of the blocking net 75 can effectively block large particles of pollutants, gather pollutants for easy salvage, and prevent them from continuing to flow into the rear water flow through the outlet 132 of the floating island 2, further protecting the ecological environment of the subsequent main channel body 1, keeping the main channel body 1 unobstructed, and reducing flood risks.
[0047] In addition, the bottom net 22 is fixed to the lower side of the guide float 21, which increases the stability of the floating island 2 and prevents the floating island 2 from being displaced due to the impact of the water flow. The pendants 23 are fixed to the lower side of the bottom net 22 and are located on the bottom of the water, which further enhances the stability of the floating island 2 and ensures that the position of the floating island 2 is stable under the action of the water flow, thereby increasing the contact area between the plant roots of the floating island 2 and the water body and improving the water purification efficiency. At the same time, the pendants 23 help to reduce the accumulation of pollutants on the front and rear sides of the floating island 2, avoid water flow obstruction, maintain a normal water flow path and speed, and reduce the risk of flooding.
[0048] Reference Figure 2 and Figure 6 The upper outer side of the second channel body section 12 forms a horizontally arranged revetment 6, which is also made of gravel and has permeable bricks 32 on the upper part. Further, in other embodiments of the present application, a guide water pipe can be laid in the gravel layer 3 to speed up the water flow into the main channel body 1.
[0049] Two columns 7 are vertically arranged in the flow-gathering part 13 of the second channel body section 12. The columns 7 are fixed to the main channel body 1 through a bracket (the bracket is not shown in the figure), and the two columns 7 are arranged along the extension direction of the main channel body 1. One of the columns 7 is located at the end position of the guide floating plate 21 extending to the flow-gathering part 13, and the other column 7 is located at a position of the flow-gathering part 13 near the outlet 132. The upper ends of the two columns 7 extend out of the water surface and bend in a direction away from the middle of the width of the main channel body 1 to form a curved portion, and the curved portion extends to the top of the revetment 6. The lower ends of the columns 7 are fixed with guide columns 72. The guide columns 72 are respectively fixed to the ends of each column 7 located underwater, and bend in a direction away from the middle of the width of the main channel body 1 to fit the outer wall of the main channel body 1 and continue to extend upward out of the water surface and be located on the upper side of the revetment 6. In this way, the guide columns 72 and the columns 7 form a U-shaped structure in the underwater part.
[0050] Reference Figure 5 and Figure 6 , the column 7 is sleeved with a sinking sleeve 73 and a floating sleeve 74, and both the sinking sleeve 73 and the floating sleeve 74 can slide to the guide column 72 through the column 7, and the positions of the sinking sleeve 73 and the floating sleeve 74 corresponding to the bracket are formed with notches to facilitate the bracket to give way. The sinking sleeve 73 has a large weight and will fall to the bottom of the water at the bottom of the column 7 and or the guide column 72 under normal conditions, while the floating sleeve 74 has a small weight and will float on the water surface, and the floating sleeve 74 has a portion extending out of the water surface to form a floating rod 741 with a certain flexibility.
[0051] A blocking net 75 is arranged between the two columns 7. The blocking net 75 has a certain degree of elasticity. The upper two ends of the blocking net 75 are respectively fixed to the floating rod 741 of the floating sleeve 74, and the lower two ends of the blocking net 75 are respectively fixed to the bottom sleeve 73. In this way, the upper side of the blocking net 75 is higher than the water surface, and the lower side is located at the bottom of the water, and is adjacent to the guide floating plate 21, and closes the outlet 132 of the gathering part 13.
[0052] In this way, the design of the column 7 and the guide column 72 can effectively support and position the blocking net 75, ensuring its stability and reliability. The combined use of the floating sleeve 74 and the sinking sleeve 73 can not only adjust the height of the blocking net 75 so that it is always in the best position, but also effectively intercept and collect floating pollutants, reduce the impact of pollutants on the plant roots of the floating island 2, and improve the water purification efficiency. In addition, when it is necessary to clean the dirt in the converging part 13, by dragging the sinking sleeve 73 upward along the guide column 72, the lower end of the sinking sleeve 73 can be moved out of the water surface. At this time, by moving the floating sleeve 74 and making it slide along the curved part of the column 7, the blocking net 75 can be tilted as a whole, so that the dirt blocked by the blocking net 75 can be quickly dumped to the shore as a whole. When the blocking net 75 needs to be replaced, the old blocking net 75 can be removed from the sinking sleeve 73 and the floating sleeve 74 and replaced with a new blocking net 75.
[0053] Furthermore, the bottom cover 73 is also fixed with a first chain 76, which can be fixed in a detachable manner such as bolts for easy removal and replacement. The other end of the first chain 76 extends out of the water and is fixed to an anchor point on the revetment 6. The floating cover 74 is fixed with a second chain 77, which can also be fixed in a detachable manner such as bolts for easy removal and replacement. A pulley 78 is also provided at the end of the first column 7. The other end of the second chain 77 extends along the curved section 71 of the column 7 and passes through the pulley 78, hanging down and also fixed to the anchor point of the revetment 6. Of course, in other embodiments of the present application, pulleys 78 can also be installed at different positions of the column 7 and the guide column 72 according to requirements.
[0054] In this way, one end of the second chain 77 is fixed to the floating sleeve 74, and the other end extends along the curved section 71 of the column 7. On the one hand, when the water flow is too large, the first chain 76 and the second chain 77 can be fixed on the shore respectively, thereby ensuring the stability of the barrier net 75 under the impact of the water flow and preventing the barrier net 75 from being washed away or displaced, thereby effectively intercepting floating pollutants and avoiding their accumulation on the front side of the floating island 2, reducing the impact on the plant roots of the floating island 2, and improving the water purification efficiency. At the same time, it ensures the smooth flow of water and reduces the risk of flooding. On the other hand, when it is necessary to salvage waste, by dragging the first chain 76, the bottom sleeve 73 can be dragged out of the water from the underwater guide column 72, thereby dragging the lower end of the barrier net 75 out of the water. At the same time, by pulling the second chain 77, the upper end of the barrier net 75 can be separated from the water surface and raised to facilitate the dumping and cleaning of waste.
[0055] In addition, the revetment 6 of the second channel section 12 is paved with permeable bricks 32 and gravel layers 3 from top to bottom, and the gravel layers 3 are paved with guide water pipes. On the one hand, this design is that when the barrier net 75 is dragged to the water surface and positioned behind the revetment 6, the water dragged by the barrier net 75 can penetrate into the gravel layer 3 through the permeable bricks 32, and then be uniformly guided to the inside of the main channel body 1 through the guide water pipes, reducing the accumulation of water on the revetment 6. At the same time, when rainwater falls on the revetment 6, it can also quickly guide the rainwater to flow out, making up for the problem of the lack of slope 4 diversion in this part, avoiding soil erosion caused by too fast rainwater runoff, and enhancing the water resource management capacity of the ecological main channel body 1. In addition, the setting of permeable bricks 32 and gravel layers 3 helps to filter impurities and pollutants in rainwater, further improve water quality, and reduce the impact on the ecological environment.
[0056] To facilitate the dragging and dropping of the first chain 76 and the second chain 77, in other embodiments of the present application, a rotating shaft can be set on the revetment 6, and the first chain 76 and the second chain 77 can be fixed to the rotating shaft. The first chain 76 and the second chain 77 can be dragged and dropped by rotating the rotating shaft by manual or electric drive.
[0057] Reference Figure 7In order to prevent other dirt from entering and flowing out of the gathering part 13 when the blocking net 75 is lifted to collect dirt, in other embodiments of the present application, a hanging rod 14 is fixed above the water inlet 131 of the gathering part 13, and a temporary protective net 141 is connected to the lower side of the hanging rod 14. The lower end of the temporary protective net 141 is a free end and is fixed with a shaping rod 142. When the temporary protective net 141 is hung down, the shaping rod 142 falls below the water surface, so that the temporary protective net 141 blocks the water inlet 131 of the gathering part 13 to prevent dirt from entering the water inlet 131 of the gathering part 13, and a rope ring 61 is fixed on the revetment 6, and a guide ring 143 is fixed on the hanging rod 14. The end of the first chain 76 close to the water inlet 131 of the gathering part 13, which is away from the sinking sleeve 73, passes through the rope ring 61 of the revetment 6 and the guide ring 143 of the hanging rod 14, and is finally fixed to the shaping rod 142 at the lower end of the temporary protective net 141.
[0058] Under normal circumstances, the bottom sinking sleeve 73 is lifted up and out of the water surface by pulling the shaping rod 142 through the first chain 76, so that dirt can enter the gathering part 13 through the water inlet 131. When the first chain 76 is pulled to drive the bottom sinking sleeve 73 to rise and drag the lower end of the blocking net 75 out of the water surface, the shaping rod 142 at the other end of the first chain 76 is lowered with the first chain 76 and falls below the water surface, playing a role of temporarily blocking dirt. When the dirt of the blocking net 75 is cleaned, the blocking net 75 is lowered again. As the bottom sinking sleeve 73 falls to the bottom of the gathering part 13, the first chain 76 will pull the shaping rod 142 up and retract the temporary protective net 141, so that the dirt can enter the gathering part 13 and be intercepted by the blocking net 75, waiting for the next cleaning.
[0059] The principles of the embodiments of this application are as follows: First, the guide float 21 on the front side of the floating island 2 can effectively disperse the water flow entering the main channel 1 under the action of the water flow, avoiding the water flow from directly impacting the floating island 2, thereby reducing the accumulation of pollutants in front of the floating island 2 and improving the purification efficiency of the floating island 2. The pollutants will enter the gathering part 13 under the guidance of the guide float 21, and the design of the blocking net 75 can effectively block large particles of pollutants, gather pollutants for easy salvage, and prevent them from continuing to flow into the rear water flow through the outlet 132 of the floating island 2.
[0060] When it is necessary to clean the dirt in the gathering part 13, the bottom sleeve 73 can be moved above the water surface by dragging the bottom sleeve 73 upward along the guide column 72. At this time, the floating sleeve 74 can be moved to slide along the curved part of the column 7, so that the blocking net 75 can be tilted as a whole, so as to quickly dump the blocked dirt to the shore as a whole. When the blocking net 75 needs to be replaced, the old blocking net 75 can be removed from the bottom sleeve 73 and the floating sleeve 74 and replaced with a new blocking net 75.
[0061] When the barrier net 75 is dragged to the water surface and positioned behind the revetment 6, the water dragged by the barrier net 75 can penetrate into the gravel layer 3 through the permeable bricks 32, and then be evenly guided to the inside of the main channel body 1 through the guide water pipe, reducing the accumulation of water on the revetment 6. At the same time, when rainwater falls on the revetment 6, it can also quickly guide the rainwater to flow out, making up for the problem of the lack of slope 4 diversion in this part, avoiding soil erosion caused by too fast rainwater runoff, and enhancing the water resource management capacity of the ecological main channel body 1. In addition, the setting of the permeable bricks 32 and the gravel layer 3 helps to filter impurities and pollutants in the rainwater, further improve the water quality, and reduce the impact on the ecological environment. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
