Description

water diversion enclosure

technical field

The invention relates to the technical field of water body pollution prevention and control, in particular to a diversion enclosure in water.

Background technique

In recent years, many water bodies have experienced eutrophication. It refers to the phenomenon that under the influence of human activities, nutrients such as nitrogen and phosphorus required by organisms enter lakes, rivers, bays and other slow-flowing water bodies in large quantities, causing algae and other plankton to multiply rapidly. It makes it difficult for sunlight to penetrate the water layer, thereby affecting the photosynthesis of plants in the water, and may cause a supersaturated state of dissolved oxygen. The supersaturation of dissolved oxygen and the lack of dissolved oxygen in water are harmful to aquatic animals and cause a large number of fish deaths. At the same time, due to the eutrophication of the water body, a large number of algae with blue-green algae and green algae as the dominant species grow on the surface of the water body, forming a layer of "green scum", which causes the harmful gases generated by the decomposition of organic substances accumulated at the bottom under anaerobic conditions and the biotoxins produced by some plankton will also harm fish. Because eutrophication water contains nitrates and nitrites, people and animals will be poisoned and diseased if they drink water with these substances exceeding a certain standard for a long time. After the formation of "green scum", the underwater algae will breathe oxygen in the water due to lack of sunlight, and cannot carry out photosynthesis. The oxygen in the water will gradually decrease, and the organisms in the water will also die due to lack of oxygen. The dead algae and organisms will be oxidized in the water again, and the water body will also become very smelly at this time, and the water resources will be polluted and cannot be reused. Cyanobacteria blooms in reservoirs are not terrible, because the naturally growing living cyanobacteria will not pollute the water quality; but if not handled properly, they will accumulate in the water area in front of the dam (downwind direction), and then die and rot to pollute the water quality. Therefore, the existing cyanobacteria protection measures at water outlets and temporary emergency algae removal measures cannot meet the needs of preventing and controlling cyanobacteria disasters, and a stronger defense front must be constructed.

In response to the above problems, the water treatment department needs to implement corresponding anti-pollution measures through water operations. Therefore, it is necessary to set up emergency engineering measures in the reservoir area, coordinate with the original algae removal facilities, effectively intercept, enrich and remove algae, and ensure water supply safety.

Second, "one embodiment" or "an embodiment" referred to herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. "In one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

Secondly, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional view showing the device structure will not be partially enlarged according to the general scale, and the schematic diagram is only an example, which should not limit the protection scope of the present invention. In addition, the three-dimensional space dimensions of length, width and depth should be included in actual production.

As shown in Figures 1 to 2, the overall structural diagram of the diversion enclosure in water according to the first embodiment of the present invention, in order to realize the partial interception of the pollutants crossed by the bottom end of the defense line after the barrier of the defense line, further reduce the content of cyanobacteria blooms in the water, and the manufacturing cost is low, and the installation is simple. Specifically, the dragging and buoyancy assembly 100 is arranged under the water surface and has a certain buoyancy; the diversion wing membrane 200 is arranged under the dragging and buoyancy assembly 100, and is suspended in the water by the dragging and buoyancy assembly 100; Floating balls, and the floating balls are connected in series to form a linear strip-shaped floating body, floating on the water surface, and the lower end of the towing and floating assembly 100 is connected to the upper end of the diversion membrane sheet 200 through a nylon installation belt 400, and the lower end of the diversion membrane sheet 200 is connected to the bottom anchor 300 through the lower part.

Further, the lower part is a chain made of manganese steel material, which is used as a load on the bottom, so that the upper and lower ends of the diversion wing membrane 200 are suspended in the water due to the buoyancy and gravity respectively, and the underwater bloom cyanobacteria is blocked to reduce its underwater content.

As shown in Figures 3 to 4, the overall schematic diagram of the intelligent barrier enclosure in the water diversion enclosure according to the first embodiment of the present invention is shown. In this embodiment, the upper end side of the towing and floating assembly 100 is connected to the intelligent barrier enclosure A through the connection line 500 to complete the limit. Through the connection with the intelligent barrier enclosure A, the algae blooms are first blocked by the intelligent barrier enclosure A and then pass through the intelligent barrier enclosure A from underwater, and then enter the water diversion enclosure to block the underwater sewage. The flow direction of the algae goes upwards to further reduce the content of cyanobacteria in the water. After the algae pass under the intelligent barrier type enclosure A, it will move to the water surface due to the diversion wing film. When it is close to the water surface due to photosynthesis, the cyanobacteria will produce air bubbles. Coupled with the effect of the wave-dissipating floating blanket, it will be difficult to sink to the bottom of the water. Most of them will float on the water surface. Salvage the cyanobacteria floating on the water surface to further reduce the cyanobacteria content in the water.

In order to block the cyanobacteria produced on the large water surface of the reservoir area in the waters far away from the water outlet and salvage and remove them in time to prevent problems before they happen; establish a core water source protection area in front of the dam to eliminate the hidden dangers of cyanobacteria disasters and ensure water supply safety. Therefore, the intelligent blocking type enclosure in this embodiment is built to block the cyanobacteria in the reservoir area. Referring to Fig. They are respectively connected to the buoyancy component 600 and the anchor component 800. The one shown in the figure is a side view. Referring to FIG. 4, it is a square blocking strip, which is suspended under the water surface, blocked by the buoyancy component 600 above the water surface, and blocked by the blocking component 700 under the water surface. More specifically, the buoyancy component 600 has a certain buoyancy when it is set on the water surface; and the barrier component 700 includes an apron skirt 701 and a water window 702, the apron skirt 701 is arranged under the buoyancy component 600 and is towed by it, and the water window 702 is arranged under the apron 701, where the apron 701 is made of industrial filter cloth, which is a filter medium woven from natural fibers and synthetic fibers. Polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, and are used to block the underwater part; the water-passing window 702 is connected to the lower end of the apron 701, and the water-passing window 702 is composed of a number of nylon belts arranged at intervals, and the hollow part is used for the bottom fluid to flow through. And the anchor assembly 800 is arranged in the slot of the mud layer M under the water. The mud layer M is connected to the bottom of the water window 702, and acts on the upper and lower ends of the blocking assembly 700 through the buoyancy assembly 600 and the anchor assembly 800, so that it can be unfolded at the bottom of the water. The anchor assembly 800 is a gabion bag made by sewing, which is placed in the corresponding slot at the bottom of the water. It includes a fixed pile 901 and a connecting rope 902. The fixed pile 901 is connected to the lower line member 702c through the connecting rope 902, and the fixed pile 901 is fixedly arranged at the bottom of the water to enhance the stability of the anchor assembly 800 and the blocking assembly 700 when the bottom is impacted by the water body, thereby improving the stability of the overall operation of the intelligent blocking enclosure in this embodiment.

In the intelligent barrier type enclosure described in the second embodiment of the present invention, the barrier assembly 700 is located below the water surface. When there are only water-passing windows 702, the effect of blocking underwater cyanobacteria is relatively low due to the relatively large gap between them. The effect of blocking pollutants at the bottom of the water is improved, and the blocking assembly 700 is protected against impact to a certain extent. Therefore, the difference between this embodiment and the first embodiment is that the blocking assembly 700 also includes a suspension assembly 703 . Specifically, referring to FIG. 3 again, the intelligent barrier enclosure includes a buoyancy component 600, a barrier component 700, and an anchor component 800. The downhill ends of the barrier component 700 are respectively connected to the buoyancy component 600 and the anchor component 800. It is shown in a side view. Referring to FIG. 4 again, it is a square barrier belt suspended under the water surface. More specifically, the buoyancy component 600 has a certain buoyancy when it is set on the water surface; and the barrier component 700 includes an apron skirt 701 and a water window 702, the apron skirt 701 is arranged under the buoyancy component 600 and is towed by it, and the water window 702 is arranged under the apron 701, where the apron 701 is made of industrial filter cloth, which is a filter medium woven from natural fibers and synthetic fibers. Polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, and are used to block the underwater part; the water-passing window 702 is connected to the lower end of the apron 701, and the water-passing window 702 is composed of a number of nylon belts arranged at intervals, and the hollow part is used for the bottom fluid to flow through. And the anchor assembly 800 is arranged in the slot of the mud layer M under the water, and is connected with the bottom of the water window 702. The buoyancy assembly 600 and the anchor assembly 800 act on the upper and lower ends of the blocking assembly 700, so that it can be unfolded at the bottom of the water. The anchor assembly 800 is a gabion bag made by sewing, which is placed in the corresponding groove at the bottom of the water. 01 and the connecting rope 902, the fixed pile 901 is connected to the lower part 702c through the connecting rope 902, and the fixed pile 901 is fixedly arranged on the bottom of the water, so as to enhance the stability of the anchor assembly 800 and the blocking assembly 700 when the bottom is impacted by the water body, thereby improving the stability of the overall operation of the intelligent blocking type enclosure in this embodiment. Further, the hanging component 703 is arranged under the apron 701 and hangs on the side of the water window 702. Here, the hanging component 703 is composed of a hanging curtain through stitching, such as the position S in the figure, which is installed and stitched by T-shaped nylon. Based on the above, it is not difficult to find that the suspension assembly 703 can also be made of industrial filter cloth. The general process of its operation is: when the bottom of the water impacts the suspension assembly 703, the magnitude of the flow velocity leads to the size of the impact force, thereby determining the size of the opening and closing between the suspension assembly 703 and the water window 702, so as to improve the effect of blocking pollutants at the bottom of the water without affecting the flow of water bodies, and has a certain impact protection for the blocking assembly 700.

Figures 5 to 8 are schematic diagrams of the overall structure of the intelligent barrier enclosure according to the third embodiment of the present invention.

Specifically, referring to FIG. 3 , the intelligent barrier enclosure includes a buoyancy component 600 , a barrier component 700 and an anchor component 800 . The upper and lower ends of the barrier component 700 are respectively connected to the buoyancy component 600 and the anchor component 800 . The figure shows its side view. Referring again to FIG. 4 , it is a square barrier belt suspended under the water surface. More specifically, the buoyancy component 600 has a certain buoyancy when it is arranged on the water surface, for example, it can be an inflatable strip floating body or a strip-shaped floating ball; and the blocking component 700 includes an apron skirt 701 and a water-passing window 702, the apron skirt 701 is arranged under the buoyancy assembly 600 and is dragged by it, and the water-passing window 702 is arranged under the apron skirt 701, where the apron skirt 701 is made of industrial filter cloth.

The anchor assembly 800 is a gabion bag made by sewing, which is placed in the corresponding groove at the bottom of the water. 01 and the connecting rope 902, the fixed pile 901 is connected to the lower part 702c through the connecting rope 902, and the fixed pile 901 is fixedly arranged on the bottom of the water, so as to enhance the stability of the anchor assembly 800 and the blocking assembly 700 when the bottom is impacted by the water body, thereby improving the stability of the overall operation of the intelligent blocking type enclosure in this embodiment. Further, the hanging component 703 is arranged under the apron skirt cloth 701 and hangs on the side of the water passing window 702. Here the hanging component 703 is composed of a hanging curtain by stitching. Based on the above, it is not difficult to find that the hanging component 703 can also be made of industrial filter cloth.

It is connected to the flat belt 702a through the splint 702b, and the lower member 702c is connected to the anchor assembly 800. Based on the above, for example, the upper and lower ends of the apron 701 are respectively connected to the upper member 701a and the middle member 701b.

9 to 18 are schematic diagrams of the overall structure of the diversion enclosure in water according to the fifth embodiment of the present invention. In the above embodiment, the buoyancy component 600 is set on the water surface and has a certain buoyancy. For example, it can be an inflatable floating body. In actual operation, changes in the water level of the water surface will cause the tension between the buoyancy component 600 and the enclosure to increase or decrease, so that the state of the enclosure in the water will change from tight to loose, resulting in a decrease in its blocking effect on cyanobacteria. In the tight state, it is easily damaged by the impact of the water flow in the water. It is necessary to provide a buoyancy component 600 that can adapt to changes in the water level. At the same time, the buoyancy component 600 floating on the water surface will be affected by the wind and will be offset, which will also lead to the deformation of the blocking defense line and reduce the blocking effect. The difference between this embodiment and the above-mentioned embodiments is that the buoyancy assembly 600 also includes a damping module 601, a lifting module 602 and a wind locking module 603, wherein the damping module 601 can generate a certain damping, and when the water level changes, it can adapt to the change of the tension of the enclosure to realize the rise or fall of the buoyancy assembly 600; the lifting module 602 can adjust the buoyancy by controlling the amount of internal water, thereby controlling the lifting of the buoyancy assembly 600; , the damping module 601 is locked to avoid rotation of the damping module 601 caused by wind force. Specifically, the damping module 601 includes a damping shaft 601a, a damping block 601b, a damping rotation sleeve 601c, and a limit screw 601d. Referring to FIG. The apron skirt 701 is located between the partition plates 601a-1 and rolled on the damping shaft 601a, and the shrinkage of the apron skirt 701 is realized by rotation. It should be noted here that the part of the damping shaft 601a between the partition plates 601a-1 can rotate relative to the damping matching area, that is, the apron skirt 701 is wound on the damping shaft 601a according to this rotation, and a recovery spring is also set in the rotation mode so that After relative rotation, it has a tendency to return to the original state, that is, the turning force. Both the thread 601a-2 and the slot 601a-3 are arranged at both ends of the damping shaft 601a outside the partition plate 601a-1, and the thread 601a-2 is in the shape of a ring, extending inward from the outermost edge of the damping shaft 601a without contacting the side of the partition plate 601a-1, that is, there is a blank area between the two, and the slot 601a-3 is set along the helical extension direction of the thread 601a-2 and touches the partition plate 601a-1 . 11-12, the damping block 601b is sleeved on the damping shaft 601a, and the outer end is limited by the stop screw 601d. The stop screw 601d can cooperate with the thread 601a-2 to change the distance, thereby adjusting the distance between the damping block 601b and the partition plate 601a-1;

Further, as shown in FIG. 13 , the damping block 601b also includes an inner convex strip 601b-1 and an outer convex strip 601b-2. In this embodiment, several inner convex strips 601b-1 are correspondingly arranged in the slot 601a-3, so that the damping block 601b can only move along the direction in which the damping shaft 601a extends, and the relative rotation of the damping shaft 601a cannot occur. The damping rotating sleeve 601c is sleeved on the damping block 601b, and one end is fixedly connected with the partition plate 601a-1, which can be realized by welding or an integrated structure. Further, the inner wall of the damping rotating sleeve 601c is also provided with a damping part 601c-1 and a through notch 601c-2. Damping fit. In addition, in this embodiment, shaft holes 601c-2 ₁ are symmetrically arranged on the inner side walls of the through notch 601c- 2 , and the shaft holes 601c-2 ₁ can interact with the wind locking module 603 .

Referring to FIG. 15 , it is a schematic diagram of the overall structure of the lifting module 602 of the present invention, which is a buoy structure. Specifically, the lifting module 602 includes an accommodation space 602a, a skirt cloth gap 602b, an air intake assembly 602c, a water inlet assembly 602d, and a drainage assembly 602e. The apron skirt 701 is wrapped on the damping shaft 601a, and the two are arranged in the accommodation space 602a to be able to rotate. At both ends, simply speaking, the lifting module 602 is actually a supporting and fixing structure for the damping module 601 . In order to realize the lifting protection of the lifting module 602, in the present embodiment, the inside of the buoy is a hollow structure, which can take in air and water. The buoyancy of the buoy on the water can be set by the water volume and gas ratio in the hollow structure. Further, the air intake assembly 602c and the water inlet assembly 602d are arranged on the top of the elevating module 602, and the drainage assembly 602e is arranged on the bottom of the elevating module 602. In this embodiment, the air inlet assembly 602c can be an air pump, and the water inlet assembly 602d The drain assembly 602e can be a water pump.

Its working principle is as follows: on the one hand, when the water surface freezes or other bad weather occurs, the buoyancy component 600 needs to be placed below the water surface, and the ratio of water and gas content in the hollow structure of the buoy is controlled through the air intake component 602c and water intake component 602d, and the buoyancy of the buoy is adjusted to make it rise or sink. On the other hand, by adjusting the damping size (the damping size can be set in advance, and the frictional force can be adjusted by rubber material or extrusion force), the buoyancy of the buoy and the traction force generated between the skirt cloth 701 and the damping magnitude are equal. At this time, the buoy can just float on the water surface. Equal, to realize the automatic adjustment of the buoyancy component 600 adaptive to water level changes, to protect the buoyancy component 600 from sinking in cold weather, and to solve the increase of the traction force on the buoyancy component 600 and the apron 701 when the water level rises, so that there is a problem that the components are easy to be pulled and damaged, and self-protection and prolonging its service life through self-adaptation.

Referring to Figures 16-18, further, in order to prevent the buoyancy assembly 600 from being blown by relatively large wind force in the water environment, the blocking defense line formed by it on the water surface will be deformed, thereby affecting the blocking effect. Therefore, in this embodiment, a wind force locking module 603 is also provided to lock the damping module 601 when encountering a strong wind force, and to unlock the damping module 601 when the water level rises. Therefore, the locking module 603 also includes a wind force deflecting plate 603a and a locking trigger block 603b. It should be noted that both of them are made of elastic materials such as rubber and have certain elasticity. Specifically, the wind deflection plate 603a includes a wind plate 603a-1 that increases the contact area with the wind force and a pin 603a-2 that locks the locking trigger block 603b.

The locking trigger block 603b includes a floating block 603b-1, an elastic piece 603b-2 and a pressing block 603b-3. Specifically, the floating block 603b-1 has a certain buoyancy, floats on the water surface, and is arranged on the top of the pressing block 603b-3. The pressing block 603b-3 has a certain angle. The floating block 603b-1 is connected.进一步的，弹片603b-2上还设置限位孔603b-5，插销603a-2能够插入限位孔603b-5中完成锁定，且压块603b-3位于通透槽口601c-2内的部分内侧面设置有锁定凸起603b-4，该锁定凸起603b-4与外凸条601b-2相抵触作用实现锁定，其中压块603b-3的折角端还设置轴603b-3 ₁ ，其两端插入轴孔601c-2 ₁内实现压块603b-3在通透槽口601c-2内的轴转动。

The working principle of the wind locking module 603 in this embodiment is as follows: when the water level is in a normal state, that is, the buoyancy of the buoyant block 603b-1 is equal to its gravity, and it just floats on the water surface, the pressing block 603b-3 is just in the transparent notch 601c-2, the pressure between the locking protrusion 603b-4 and the outer convex strip 601b-2 meets the locking condition, and it is in the locked state at this time, and the length of the skirt 701 is stable. And when the water level rises, the buoyancy force received by the floating block 603b-1 will increase, causing the floating block 603b-1 to rise. The inside of the rotating shaft 601a is pulled out and becomes longer to realize the self-adaptation to the rise of the water level. During this process, if there is a strong wind force, the wind force deflection plate 603a is blown to deflect in the direction of the wind force. Based on the above, it is not difficult to find that when the water level drops, it is only necessary to adjust the lifting module 602 to control the relationship between the floating block 603b-1 and the water surface, that is, the buoyancy of the floating block 603b-1. Similarly, the damping module 601 can be locked and unlocked.

The invention provides an application of diversion enclosure in water, which is illustrated by taking the application of Yuqiao reservoir as an example. Specifically, for the eutrophication of the water body caused by the bloom of algae on the surface of the reservoir, because of the eutrophication of the water body, a large number of algae with cyanobacteria and green algae as the dominant species grow on the surface of the water body, forming a layer of "green scum", which causes the harmful gases generated by the decomposition of organic substances accumulated at the bottom under anaerobic conditions and the biotoxins produced by some plankton will also harm fish. Because eutrophication water contains nitrates and nitrites, people and animals who drink water with these substances exceeding a certain standard for a long time will also be poisoned and cause diseases, so that water resources will be polluted and cannot be reused. Therefore, it is necessary to build a barrier line of defense (i.e. water diversion enclosure) on the surface of the reservoir to block the algal blooms and cyanobacteria that grow on the water surface to prevent it from polluting water resources. The underwater sediment surface slotting method described in this embodiment is applied to the construction of the barrier line of defense of the reservoir. The operations of its construction are such as underwater slotting, underwater anchoring, and straight line layout operations. In the east of Jixian County, it is one of the national key large reservoirs. The dam site of the reservoir was built at the outlet of the Zhou River, the left tributary of the Jiyun River, and it is one of the main projects for harnessing the Jiyun River. The controlled drainage area is 7060km2, with a total storage capacity of 1.559 billion m3. The main rivers entering the reservoir are the Lin River, Sha River and Li River in the upper reaches, with an average annual runoff of 506 million m3. After the construction of the Luan River into Tianjin Project in 1983, Yuqiao Reservoir was officially included in the management of the Luan River into Tianjin Project and became the only water source in Tianjin. Its main functions are flood control and urban water supply, while taking into account irrigation and power generation. The barrage is a homogeneous earth dam, that is, the reservoir dam in this embodiment is 600m, its total length is 2222m, the maximum dam height is 24m, the dam crest elevation is 28.72m, and the diameter of the water discharge tunnel (and power generation tunnel) is 5m. 0 kW. The spillway is an open weir sluice, eight-hole gate, with a net width of 80m and a maximum flood discharge capacity of 4138m3/s. The downstream of the reservoir directly affects the low-lying areas of Jixian, Baodi, Ninghe, Yutian, Hangu and other counties (districts) with a population of nearly one million and more than 8 million mu of cultivated land. Urban water supply is the main priority, while irrigation and power generation are also taken into consideration. Therefore, the water quality of Yuqiao Reservoir directly affects the water supply safety of downstream cities.

The input of nitrogen and phosphorus led to the eutrophication trend of the water body of Yuqiao Reservoir. It is generally believed that when the concentrations of N and P in the water body reach 0.2mg/L and 0.02mg/L respectively, algae will grow in large numbers. The water quality of Yuqiao Reservoir is affected by the upstream water and the surrounding environment of the reservoir. In recent years, the annual average value of total nitrogen has been higher than 1.15mg/L, and total phosphorus has been higher than 0.025mg/L. During the flood season from June to September, a large amount of nitrogen and phosphorus loads are input into the reservoir along with the runoff, providing a nutritional basis for the growth of cyanobacteria and creating preliminary conditions for cyanobacteria blooms. The rich nutrients also make the aquatic plants of some dominant species in the reservoir, such as weeds, grow enormously, and nearly 95,000 m3 of weeds are salvaged from the water surface of the reservoir area every year. Except for the main channel of the Zhou River, the growing area of Smilax has basically covered the entire reservoir area. In addition, Yuqiao Reservoir's own morphological characteristics also provide favorable conditions for water eutrophication and cyanobacteria blooms. In the north, due to the small water depth, the light radiation can reach relatively deep underwater, so the water temperature is relatively high, and the water flow rate is slow. No matter whether it is windy or not, it has little effect on improving its flow state, so it is more suitable for the reproduction and accumulation of algae, which makes this area a high-value area of phytoplankton in the reservoir. Affected by multiple conditions, Yuqiao Reservoir is prone to cyanobacteria blooms in summer, posing a threat to the safety of urban water supply. But in fact, cyanobacteria blooms in Yuqiao Reservoir are not terrible, because the naturally growing living cyanobacteria will not pollute the water quality; but if not handled properly, they will accumulate in the water area in front of the dam (downwind direction), and then die and rot to pollute the water quality. Therefore, it is necessary to take advantage of the natural characteristics of cyanobacteria drift and accumulation, and with the help of the topography, wind and water flow of Qiao Reservoir, set up blocking-diversion-algae removal facilities on the path of its drift and accumulation to effectively enrich and remove cyanobacteria. At present, although emergency measures have been taken in front of the dam to remove the accumulated blue-green algae, water pollution has already formed. The content of blue-green algae in the water supply is too high, and the pollutants released by the decomposition of blue-green algae have seriously affected the water supply quality.

Algae blooms breed on the large water surface of Qiao Reservoir. When the climate conditions are suitable, they are concentrated in the surface warm water layer. Under the action of the southeast monsoon, they migrate and accumulate with the wind-induced surface flow to the waters in front of the dam, causing impact pollution (algae bloom outbreak), and enter the water supply channel system with the water flow. Therefore, the large water surface of Yuqiao Reservoir is the source of algae blooms, and the migration and accumulation with wind is an important mechanism affecting water supply. It is planned to build an algae bloom barrier defense line at the throat of the dam in the reservoir area (from the north bank dam to the south bank grassland) to cut off the migration and accumulation of algae blooms to the front of the dam. The barrier defense line is located at the throat of the bridge reservoir dam, between the north bank dam and the south bank grassland. Dead rot pollutes the water quality; the main project of this blocking line of defense consists of 2 flexible intelligent enclosures with a spacing of 700m (i.e. the intelligent blocking type enclosure described in the present invention). At the deep groove of the original river channel at the bottom of the reservoir, a water mesh window is set at the bottom of the enclosure to allow the flow of water with low algae content in the deep layer to pass through, so as to supplement the water required for normal water supply.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
