Description

Aquatic water conservancy diversion enclosure

Technical Field

The invention relates to the technical field of pollution prevention and treatment of water bodies, in particular to an underwater diversion enclosure.

Background

In recent years, eutrophication occurs in many water bodies, which means that under the influence of human activities, nutrient substances such as nitrogen, phosphorus and the like required by organisms enter slow-flowing water bodies such as lakes, rivers, lakes, bays and the like in a large amount, algae and other plankton are rapidly propagated, the dissolved oxygen in the water bodies is reduced, the water quality is deteriorated, and fishes and other organisms die in a large amount, wherein floating algae are propagated in a large amount to form water bloom (a natural ecological phenomenon of the large-scale algae propagation in fresh water bodies), the water quality of the water bodies is influenced by the eutrophication, the transparency of water is reduced, sunlight is difficult to penetrate through a water layer, and photosynthesis of plants in the water is influenced, so that a supersaturation state of the dissolved oxygen is possibly caused. Oversaturation of dissolved oxygen and less dissolved oxygen in water are harmful to aquatic animals, resulting in massive death of fish. Meanwhile, because the water body is eutrophicated, a large amount of algae taking blue algae and green algae as dominant species grow on the surface of the water body to form a layer of green scum, so that harmful gas generated by decomposing organic matters accumulated on the bottom layer under anaerobic conditions and biotoxin generated by some plankton can also hurt fish. Because the eutrophic water contains nitrate and nitrite, people and livestock drink water with the content exceeding a certain standard for a long time, the water can also be poisoned and pathogenic. After the green scum is formed, the underwater algae cannot breathe oxygen in water due to the fact that sunlight irradiation is not available, and photosynthesis cannot be performed. Oxygen in water is gradually reduced, and aquatic organisms die due to insufficient oxygen. Dead algae and organisms oxidize in water, which can become very odorous and the water resource can be contaminated and not reused. The blue algae bloom in the reservoir is not afraid, because living blue algae growing naturally does not pollute the water quality; however, if the disposal is not enough, the water can be accumulated at the height of the water area (downwind direction) in front of the dam, and then the water is dead, rotted and polluted. Therefore, the existing protection measures of blue algae at the water outlet and temporary emergency algae removal measures cannot meet the requirements of preventing and controlling blue algae disasters, and stronger defense lines must be constructed.

Aiming at the problems, the water treatment department needs to execute corresponding anti-pollution measures in a water operation mode, so that emergency engineering measures are necessary to be arranged in a warehouse area to operate in coordination with the original algae removal facility, water bloom algae are effectively intercepted, enriched and removed, water supply safety is ensured, and a blocking defense line is built through water operation such as water bottom slotting, water bottom anchoring, linear arrangement and the like, so that the blocking defense line is used for preventing and controlling water quality pollution caused by water bloom blue algae breeding in a pollution manner.

On the other hand, through adjusting the damping size (can set up the damping size in advance, adjust the size of frictional force through rubber material or extrusion dynamics), make the flotation pontoon buoyancy equal with damping size between the apron cloth 701 and produce traction force, the flotation pontoon can just in time float on the surface of water, the water level on the surface of water is because bad weather water level rises, lead to the traction force that buoyancy produced to be greater than damping force, damping pivot 601a takes place to rotate this moment, and be pulled out the part in the apron cloth 701 until traction force equals with damping force size again, realize buoyancy module 600 self-adaptation water level variation's automatically regulated, can carry out the protection of sinking to buoyancy module 600 under cold weather, and the increase of traction force that buoyancy module 600, apron cloth 701 received when solving the water level rising, thereby there is the problem that the part is easy to pull damage, through self-adaptation protection and extension its life.

Referring to fig. 16-18, further, to avoid the greater wind force in the water environment blowing the buoyancy module 600 results in a distortion of the barrier line formed on the water surface, thereby affecting the barrier effect.

The working principle of the wind power locking module 603 in this embodiment is as follows: when the water level is in a normal state, that is, the buoyancy of the floating block 603b-1 is equal to the gravity of the floating block, the floating block 603b-1 just floats on the water surface, the pressing block 603b-3 just sits in the through notch 601c-2, the pressure between the locking protrusion 603b-4 and the outer protrusion 601b-2 meets the locking condition, the floating block is in a locking state, and the length of the apron cloth 701 is stable. When the water level rises, the buoyancy force exerted by the floating block 603b-1 will increase, so that the floating block 603b-1 rises, at this time, the pressing block 603b-3 is driven to rotate axially, the lower half part of the bevel end of the pressing block 603b-3 is tilted upwards, the pressure between the locking protrusion 603b-4 and the outer protrusion 601b-2 is reduced, at this time, in an unlocking state, the damping rotating sleeve 601c can rotate, the length of the enclosure skirt cloth 701 is pulled out from the damping rotating shaft 601a to be prolonged, the self-adaption of the water level rise is realized, in the process, if strong wind force is met, the wind force deflection plate 603a is blown, the direction of the wind force is deflected, at this time, the plug pin 603a-2 is inserted into the limiting hole 603b-5 to prevent the upward movement trend of the floating block 603b-1, the locking is performed, and the damping rotating sleeve 601c cannot rotate, so that the locking of the damping module 601 in strong wind force is completed. Based on the above-mentioned findings, when the water level is lowered, only the lifting module 602 needs to be adjusted to control the relationship between the floating block 603b-1 and the water surface, that is, the magnitude of the buoyancy force exerted on the floating block 603b-1, and the same can be said that the damping module 601 can be locked and unlocked.

The invention provides application of a diversion enclosure in water, which is illustrated by taking application of a bridge reservoir as an example. Specifically, for water eutrophication caused by the growth of water bloom algae on the surface of the reservoir, a large amount of algae taking blue algae and green algae as dominant species grow on the surface of the water body to form a layer of green scum, so that harmful gas generated by decomposing organic matters accumulated on the bottom layer under anaerobic conditions and biotoxin generated by some plankton can also hurt fish. Because the eutrophic water contains nitrate and nitrite, people and livestock drink water with the content exceeding a certain standard for a long time, the water can be poisoned and pathogenic, and water resources can be polluted and cannot be reused. Therefore, a blocking line (i.e. a diversion enclosure in water) needs to be constructed on the surface of the reservoir to block water bloom and blue algae growing on the water surface to prevent the water resource from being polluted, and the method for grooving the surface layer of the underwater sediment in the embodiment is applied to construction engineering of the blocking line of the reservoir, such as underwater grooving, underwater anchoring, linear layout operation and the like, and is exemplified by a bridge reservoir, particularly an anti-pollution blocking line applied to the bridge reservoir, and is exemplified by the bridge reservoir being located in the city and east of Tianjin thrice county, which is one of the important large reservoirs in China. The reservoir dam site is built at the outlet of the branch state of the thistle canal left, and is one of the main projects for treating the thistle canal. The control flow area is 7060km2, and the total storage capacity is 15.59 hundred million m3. The upstream main warehouse-in rivers are the river, the sand river and the Li river, and the average annual runoff is 5.06 hundred million m3. After the construction of the water inlet project of Luan in 1983, the water inlet project of Luan is formally incorporated in the bridge reservoir, and is managed as the only water source of Tianjin, the main functions of the water inlet project are mainly flood control and urban water supply, irrigation, power generation and the like are considered, and in the bridge reservoir, the reservoir hub project comprises a barrage, a water discharge hole, a spillway and a hydropower station. The barrage is a homogeneous earth dam, namely a water reservoir dam 600 in the embodiment, the total length of the barrage is 2222m, the maximum dam height is 24m, the dam top elevation is 28.72m, the hole diameter of a water discharge hole (concurrently generating hole) is 5m, the water discharge hole is a water discharge culvert A in the embodiment, running water in a bridge reservoir realizes operations such as reservoir water collection, water discharge and the like through the water discharge culvert A, four through-flow units are arranged at a power station behind the barrage, and the total assembly machine is 5000 kilowatts. The spillway is an open weir gate, an eight-hole gate, the clear width is 80m, the maximum flood discharge capacity is 4138m3/s, the direct influence range of the downstream of the reservoir is near to millions of people in low-lying areas of various counties (areas) such as thrips, bao Ding, ning river, yutian, hangu and the like, 800 more than ten thousand acres of cultivated land is built in 1983, the water is formally introduced into the water introducing project of Luan after the construction of the water introducing project is built in the bridge reservoir, the water source area which is the only water source area of Tianjin is formally managed, the main functions of the water source area are flood prevention, urban water supply and the water supply safety of the downstream of the water source area is directly influenced by the water quality of the bridge reservoir.

The input of nitrogen and phosphorus causes the water body of the bridge reservoir to show eutrophication trend. It is generally believed that algae will grow in large amounts when the N, P concentration in the body of water reaches 0.2mg/L and 0.02mg/L, respectively. In recent years, the average value of total nitrogen in bridge reservoirs is always higher than 1.15mg/L and the total phosphorus is higher than 0.025mg/L under the influence of upstream water supply and the surrounding environment of the reservoirs. The flood season is 6-9 months, a large amount of nitrogen and phosphorus loads are input into the reservoir along with runoff, a nutrition foundation is provided for the growth of blue algae, and preliminary conditions are created for the blue algae bloom. The rich nutrition also makes the growth of water grass such as water pondweed in the dominant population of the reservoir extremely large, and the water pondweed is fished out from the water surface of the reservoir area by approximately 9.5 ten thousand m < 3 > each year. The growth area of the potamogeton crispus is basically covered with the whole reservoir area except for the main river channel of the state river. In addition, the morphological characteristics of the bridge reservoir also provide favorable conditions for water eutrophication and cyanobacterial bloom outbreak. The water depth is small in the north, the light radiation can reach the deep underwater position relatively, so that the water temperature is high, the water flow speed is low, no matter whether wind exists or not, the effect of improving the flow state of the water is not great, and therefore the water is more suitable for the propagation and aggregation of algae, the propagation of algae is facilitated, and the area becomes a high-value area of reservoir phytoplankton. Under the influence of multiple conditions, blue algae bloom is extremely easy to form in summer of the bridge reservoir, and the safety of urban water supply is threatened. However, the blue algae bloom in the bridge reservoir is not afraid, because living blue algae growing naturally does not pollute the water quality; however, if the disposal is not enough, the water can be accumulated at the height of the water area (downwind direction) in front of the dam, and then the water is dead, rotted and polluted. Therefore, the natural characteristic of blue algae drift gathering must be utilized, and by means of the topography, wind power and water flow of the bridge reservoir, a blocking-guiding-algae removing facility is arranged on the drift gathering path, so that blue algae can be effectively gathered and removed, the blue algae disaster in the water area in front of the dam can be prevented, the blue algae population base number of the whole reservoir area can be reduced by removing a large amount of blue algae, the contained nutrient substances can be taken away, and the accumulation of nutrient salts in the water body and the development of blue algae bloom can be effectively restrained. At present, although emergency measures are taken before a dam to remove accumulated blue algae, water quality pollution is formed, the blue algae content in water supply is too high, and pollution substances released by decay and decomposition of the blue algae seriously affect the water quality of the water supply.

Algae bloom grows on the large water surface of the bridge reservoir, is concentrated on a warm water layer on the surface when the climate conditions are proper, migrates and gathers along with the direction of the surface of the aquatic product to the water area in front of the dam under the action of southeast monsoon, causes impact pollution (algae bloom outbreak), and enters a water supply channel system along with water flow. Therefore, the large water surface of the bridge reservoir is a source for algae bloom growth, and the migration and accumulation along with wind are important mechanisms for influencing water supply. The method comprises the steps of constructing an algae bloom blocking line at a front throat part of a reservoir dam (a north bank dam to a south bank grassland) so as to cut off a path for migration and accumulation of algae bloom towards the front of the dam, wherein the blocking line is selected at the front throat part of a bridge reservoir dam and positioned between the north bank dam and the south bank grassland, has a span of approximately 1700m and a maximum water depth of 12m, intercepts and controls the large water surface of the reservoir, which is 98% of the upstream of the blocking line, and timely catches and clears the intercepted algae so as to prevent the algae from dying, rotting and polluting water; the main engineering of the blocking defense line consists of a flexible intelligent enclosure with a distance of 2 channels of 700m (namely the intelligent blocking type enclosure disclosed by the invention), wherein the enclosure is provided with an upper water outlet surface, is provided with a lower reservoir bottom, spans across two banks, separates water bodies at two sides, cuts off water flow on the surface of a wind generator, and intercepts water bloom algae migrating along with the water flow on the surface. The bottom of the enclosing partition is provided with a water passing net window at the deep groove part of the original river channel at the bottom of the reservoir, so that water flow with lower deep algae content is allowed to pass through, and the water quantity required by normal water supply is supplemented.
