Description

Screen apparatus of blocking green algae for intake tower

The present invention relates to a rust bed screen device for a water intake tower, and more particularly, to a rust bed screen device for a water intake tower in which equipment economics and compatibility are improved, and the depth of immersion by buoyancy is easily adjusted.

In general, a water intake tower is a device installed in a river, lake, or reservoir to take in raw water from a water source and supply it to a waterway, and the water intake tower is provided with an intake port through which the raw water is introduced. At this time, the water intake tower is connected to and communicates with a pipe whose bottom surface is directed to the water treatment plant. Accordingly, the raw water collected through the water intake tower is moved along the pipe, is pulled upward by a water intake pump connected to the pipe, passed through the water treatment plant, and then purified and then discharged.

Here, when the raw water is drawn into the intake port, algae or various suspended substances are introduced along with the raw water along the intake port to reduce the water quality of the intake port and block the intake port.

In particular, a green algae phenomenon in which the water color changes to green or blue-blue due to the complex action of four factors: excessive nutrients, warm temperature, a lot of light, and a slow flow rate during the summer season, and green algae and blue-green algae multiply in large quantities. This happens.

At this time, the green algae phenomenon often occurs in a reservoir with a slow flow rate or in a water intake area downstream of a river, so that when raw water is ingested, algae floating on the surface of the water may flow into the intake port along the flow of water. Accordingly, the inflow of the algae may cause a problem that the water source water is contaminated or the intake port is clogged, and the water treatment cost may increase in the process of removing the algae in the collected water. Thus, in order to prevent the above problems, a green algae blocking film was installed along the outer periphery of the water intake tower of the green algae frequent water source.

That is, in the related art, in preparation for the occurrence of green algae and blue-green algae, which have characteristics mainly distributed on the water surface, the green algae blocking film was installed and operated around the water intake tower when green algae occurs, and the raw water in the lower part of the algae concentration was low. In detail, when a green algae phenomenon occurs or contaminants are floating on the water surface due to a water pollution accident, the green algae blocking film is placed on the top of the raw water to induce the intake of deep water up to a depth of 5 to 6 m to minimize the inflow of pollutants and algae. .

In detail, the conventional green algae blocking film is a concrete block installed on the bottom of the water with a fixed wire and a connection chain by floating a float part integrally formed with a prevention film on the water surface in a certain range of the outer circumference of the water intake tower to form a boundary border around the outer circumference of the water intake tower. It has a structure to connect and install each.

However, in the conventional green algae blocking film, in order to fix the float part, the operator inevitably has to dive underwater and perform underwater work, and it is very difficult to place the concrete block underwater, which may lead to safety accidents. There was a problem with low, manpower consumption.

In addition, the green algae blocking film has a problem that the convenience of work is deteriorated due to inconvenient selection of water intake because the administrator must always observe the change in the water level of the river, lake, or reservoir in real time and adjust the height of the prevention film to suit the water intake quality. .

Moreover, the green algae blocking membrane has a problem that a lot of work time is consumed because the manager must manually adjust the length of the fixing wire and the connecting chain between the float part and the concrete block by manually submerging when ascending and descending due to a change in water level. .

In addition, in order to keep the green algae blocking film in a floating state in the raw water, a separate buoyancy member having a general known buoyancy such as wood, air tube, styrofoam, or a box structure containing air is required, so equipment economics are reduced. There was a problem.

Moreover, when the buoyancy member is separated from the green algae blocking membrane due to a sudden change in flow velocity and water level, etc., it is sucked into the intake port of the water intake tower and blocks the entrance, thereby reducing water intake stability.

In addition, the water intake tower is provided with a connecting means such as a rope or a chain for connecting and supporting the green algae blocking film so that the flow of the green algae blocking film in the horizontal direction is constrained and moves upwardly in a state spaced apart from the water intake tower at regular intervals. Accordingly, when the green algae blocking film is installed, a connection work with the water intake tower is required, and installation convenience is reduced.

In addition, since the length and the connection position of the connection means change according to the shape and size of each water intake tower, the connection means is difficult to be used interchangeably with various water intake towers, so that the applicability of the device is deteriorated.

In order to solve the above problems, the present invention aims to provide a screen device for a water intake tower in which economical efficiency and compatibility of equipment are improved, and the depth of immersion by buoyancy can be easily adjusted.

In order to solve the above problems, the present invention provides a plurality of lifting support piles which are spaced apart at regular intervals on the outside of a water intake tower in which raw water is taken in, and the lower end is fixed upright in the soil section of the bottom of the water source where raw water is received; And it is inserted into the inside of the plurality of lifting support piles to guide the lifting by buoyancy, but the upper and lower sides are opened and the lateral direction of the intake port through which the raw water is introduced is selectively shielded. It provides a rust bed screen device for a water intake tower that extends to a length and includes a rust end wall in which a hollow buoyancy control space is formed inside the rim side.

Here, the rust end wall is provided so that the upper end thereof is floated above the water surface, and is selectively raised and lowered according to the amount of water stored in the buoyancy control space to change the immersion depth, but the preset immersion length is the lower end of the rust end wall. It is preferable that it is set to be disposed below the lowermost end of the.

And, the rust end wall is provided with an inner blocking film and an outer blocking film spaced radially outwardly of the inner blocking film to be disposed opposite to each other, and the inner blocking film and the lower end of the outer blocking film are integrally connected to control the buoyancy between It is desirable that a space is formed.

At this time, it is preferable that the rust end wall is spaced apart from the water intake tower corresponding to a predetermined spacing distance so that an intake passage through which the raw water flows into the intake port is formed between the inner surface and the intake tower.

On the other hand, a bird detection sensor provided at the lower end of the rust wall to detect the concentration of algae, and a bird detection sensor provided at the upper end of the lifting support file to receive measurement data from the bird detection sensor and detect when it is detected above a preset concentration It is preferable to further include a signal communication unit for transmitting the signal to the server system.

Through the above solution means, the present invention provides the following effects.

First, as the lower end of the rust barrier is submerged, the algae proliferate on the water surface near the intake tower for photosynthesis and block the lateral direction of the intake port from the concentrated band-shaped algae layer, thereby minimizing the inflow of green algae into the intake port, and As the water quality of water is improved, water purification costs are reduced, and water treatment economics can be remarkably improved.

Second, when installed in the existing water intake tower, installation is completed simply by installing the lifting support pile on the outside and inserting the rust end wall inside the lifting support pile, so it can be easily applied to the previously installed water intake tower, so the compatibility of the device is remarkable. It can be improved.

Third, the rust barrier is easy to adjust the buoyancy because the buoyancy is changed according to the amount of water stored in the buoyancy control space connected to the pumping means for supplying and discharging water, so that the depth of flooding is controlled, and it is easy to adjust the buoyancy. The water quality of the raw water to be taken can be maintained satisfactorily by fluidly controlling the depth of immersion according to factors.

Hereinafter, with reference to the accompanying drawings will be described in detail the screen device for a water intake tower for a rust according to a preferred embodiment of the present invention.

This is an example projection cross-sectional view showing the state applied at the time of occurrence.

On the other hand, the present invention is mainly applied to the water intake tower 200 installed in a water source such as a river, lake, or reservoir in order to stably intake high-quality raw water (1). At this time, the water intake tower 200 has a lower end embedded in the bottom of the water source, and one side of the water intake tower 200 is connected to and communicated with one end of the pipe. Thus, the raw water taken into the water intake tower 200 flows out of the water intake tower along the pipe, and is drawn up by a water intake pump connected to the other end of the pipe. In addition, the raw water drawn upward by the water intake pump is moved along a water pipe connected to the water treatment facility to be purified by a water treatment process and then discharged.

At this time, the water intake tower 200 is installed at a point where the water depth is greater than or equal to a certain depth, and collects the raw water 1 through an intake port 200a installed on the side. Here, the intake port 200a means an inlet through which the raw water 1 to be taken in flows into the intake tower 200, and at least one or more along the circumference of the intake tower 200 at the side of the intake tower 200 It is equipped with. In addition, one or more of the water intake ports 200a may be formed at different heights in the water intake tower to receive the raw water 1 having a different depth.

In this case, the present invention is preferably understood as a device provided to cover the water intake port 200a installed within the height at which the green algae layer 3 is formed from the water surface by the mass proliferation of algae in the water source.

As shown in FIGS. 1 to 4, the rust floor screen apparatus 100 for a water intake tower according to an embodiment of the present invention includes an elevation support pile 10 and a rust end wall 20.

In detail, the lifting support piles 10 are provided in plural and are spaced apart at regular intervals outside the water intake tower 200 where the raw water 1 is intaken. At this time, it is preferable that the lower end of the elevating support pile 10 is embedded in the soil section 2 of the bottom of a water source such as a river or lake, a dam, or a reservoir in which the raw water 1 is accommodated and fixed upright.

Meanwhile, the elevation support pile 10 may be provided with a separate fixing member on the bottom of the water source so that the lower end thereof is supported, so that the elevation support pile 10 may be inserted into the fixing member to be fixedly coupled. In this embodiment, it is described and illustrated as an example that the lower end of the lifting support file 10 is installed so as to be embedded and fixed without having the separate fixing member.

Accordingly, since the fixing member for fixing is not required, equipment economics can be improved, and installation is completed simply by embedding the lower end in the soil section 2, so that the convenience of work can be improved.

In addition, each of the lifting support pile 10 is preferably installed so as to be spaced apart at equal intervals from the outer periphery of the water intake tower 200 in the radial direction. In this case, the elevating support piles are provided in three to four, and may be arranged at regular intervals from each other.

In addition, the rust end wall 20 is inserted into the elevation support pile 10 so that a part of it is floated on the water surface of the water source. In addition, the rust end wall 20 is arranged in close contact with the inner side of the elevation support pile 10 so that the elevation is guided along the elevation support pile 10 and moves only up and down.

At this time, it means that the rust end wall 20 is prevented from moving in the horizontal direction by the lifting support file 10, but at a fine interval so that insertion into the inside of the lifting support file 10 is not interfered. It is desirable to understand in the sense that they are arranged oppositely.

Here, since the rust end wall 20 is provided independently from the water intake tower 200 because insertion is guided by the lifting support pile 10 and the placement position is fixed, a separate connection and fixation with the water intake tower 200 No connecting member is required. Therefore, when the lifting support pile 10 and the rust even end wall 20 are installed, it does not affect the water intake tower 200, so that when the lifting support pile 10 is installed outside, one of the rust even end wall 20 Since it can be applied to other water intake towers, the compatibility of the device can be significantly improved.

In addition, the upper and lower sides of the rust end wall 20 are opened up and down to surround the outer circumference of the water intake tower 200 disposed in the inner center of the lifting support pile 10. Here, it is preferable to understand that the upper and lower sides are opened is a ring or a donut shape through which the central part excluding the outer border is penetrated to surround the water intake tower 200.

On the other hand, the shape of the ring or donut is not limited to a circular shape, and may cover various shapes in which the central portion is opened but the outer edge is left. For example, when the rust end wall 20 is provided in a circular shape, the flow may be restricted by three to four lifting support piles 10, and when provided in a quadrangular shape, the flow can be constrained. Elevating support files 10 may be provided.

At this time, in this embodiment, the rust end wall 20 is provided in a circular shape, and the four lifting support piles 10 are described and illustrated as an example that are arranged to constrain all directions of the rust end wall 20 .

In addition, the rust end wall 20 extends to a preset immersion length h1 to selectively cover the lateral direction of the intake port 200a into which the raw water 1 flows, and has a hollow shape inside the outer border. It is preferable that the buoyancy control space 21 is formed.

In detail, referring to FIG. 2, the outer edge of the rust end wall 20 includes an inner blocking layer 22 and an outer blocking layer 23, and between the inner blocking layer 22 and the outer blocking layer 23 It is preferable to understand that the buoyancy control space 21 is formed.

That is, the water intake tower 200 is wrapped by two layers of blocking film, and the inner blocking film 22 refers to a blocking film located close to the water intake tower 200. In addition, the outer blocking layer 23 is spaced radially outwardly from the inner blocking layer 22 and is disposed to surround the inner blocking layer 22. Accordingly, the inner blocking layer 22 and the outer blocking layer 23 may be disposed to face each other at regular intervals.

In this case, the inner blocking film 22 and the outer blocking film 23 have a lower end 24 integrally connected to the outer space. Accordingly, the buoyancy control space 21 in which the lower end 24 is sealed is formed between the inner blocking film 22 and the outer blocking film 23.

Here, it is preferable to understand that the buoyancy control space 21 is a storage space in which water is stored, and the depth at which the rust wall 20 is submerged according to the amount of water stored in the buoyancy control space 21 may vary. I can.

On the other hand, the rust end wall 20 increases the amount of water stored in the buoyancy control space 21, and when it is submerged, the upper end is raised above the water surface, and the lower end 24 is the raw water (1). ) Is formed to extend to a predetermined immersion length h1 to cover the water intake port 200a of the water intake tower 200 from which water is taken. At this time, it is preferable to understand that the preset immersion length h1 is a length corresponding to the maximum depth submerged from the water surface when the rust end wall 20 is maximally submerged.

That is, the rust end wall 20 is maximally submerged and the lower end 24 is extended so as to correspond to the preset submerged length h1, but has a preset floating length h2 so that a part is floated above the water surface and exposed. It is preferably formed in a length including the upper end. Here, the preset floating length (h2) is the length exposed above the water surface so that the raw water 1 flowing through the water source does not flow from the outside of the rust end wall 20 to the inside beyond the upper end due to sudden flow velocity fluctuations or waves. It is desirable to understand as.

Accordingly, it is preferable that the amount of water stored in the buoyancy control space 21 has a maximum amount of water when the rust end wall 20 is submerged to a depth corresponding to the preset submerged length h1. That is, the maximum amount of water stored inside the buoyancy control space 21 may be limited so as not to be submerged to a depth greater than the preset submersion length h1.

On the other hand, when the amount of water stored in the buoyancy control space 21 exceeds the maximum amount of water due to a worker's work error, etc., the green algae are stored in the elevation support pile 10 to prevent flooding of the rust end wall 20. It may be provided with a locking jaw that restricts the downward movement of the blocking wall 20. In this case, the locking jaws may be formed at a depth corresponding to the preset immersion length h1 to prevent the rust end wall 20 from being submerged to a depth equal to or greater than the preset immersion length h1.

Here, since the depth of immersion is adjusted in response to a change in the amount of water stored in the buoyancy control space 21, the rust end wall 20 rises and descends in the vertical direction along the lifting support pile 10 and is arranged opposite to the inner surface. It is possible to selectively cover the intake port (200a).

In detail, when the amount of water stored in the buoyancy control space 21 is small, and the lower end 24 of the rust end wall 20 is disposed above the uppermost end 200b of the water intake port 200a, the intake port 200a is opened. do.

In addition, when the lower end portion 24 of the buoyancy control space 21 is disposed below the lowermost end portion 200c of the water intake port 200a by increasing the storage amount, the intake port 200a has a side direction of the rust end wall 20 ) And is partitioned from the outside of the rust end wall 20. Accordingly, the raw water 1 outside the rust end wall 20 is blocked by the rust end wall 20 and does not flow into the intake port 200a, and the outer periphery of the rust end wall 20 It flows along the perimeter.

At this time, the word that the intake port 200a is covered by the rust end wall 20 is not completely sealed, but the space between the intake port 200a and the inner side of the rust end wall 20 is ) It is desirable to understand that it is separated from the outer space.

That is, the rust end wall 20 is spaced apart from the outer circumference of the water intake tower 200 at a predetermined spacing distance w1. At this time, the predetermined spacing (w1) means the intake passage (f) through which the raw water (1) flows into the intake port (200a) between the intake port (200a) and the inner surface of the rust end wall (20). It is desirable to understand as spaced apart to form.

On the other hand, when the distance between the rust end wall 20 and the water intake tower 200 is small, the amount of the raw water 1 flowing through the space formed by the space is small, so the amount of water intake passing through the water intake port 200a is reduced. Can be. Therefore, the rust-even end wall 20 has a predetermined spacing interval in consideration of the cross-sectional area of the intake passage (f) so that the raw water (1) flowing through the intake passage (f) has a flow rate corresponding to a preset amount of water intake ( It is preferable to be spaced apart according to w1).

Therefore, in a state in which the water intake port 200a is covered by the rust end wall 20, the water intake passage f flows the raw water 1 flowing under the rust end wall 20 to the water intake port 200a ) Rises into the space between the rust end wall 20 and has a path flowing into the intake port 200a.

At this time, the rust end wall 20 is prevented from horizontal flow due to wind, running water, or waves as the position of the rust end wall 20 is fixed by the lifting support pile 10, so that the inner circumferential surface of the rust end wall 20 and the water intake tower (200) The predetermined separation distance w1 may be maintained between the outer circumferential surfaces. Accordingly, the raw water 1 is introduced into the intake port 200a at a constant flow rate, and water can be stably taken in.

On the other hand, the rust barrier 20 may be made of stainless steel or polyvinyl chloride (PVC) material. At this time, although the material of the rust end wall 20 is not limited, it is possible to float on the water surface, but it is preferable that the raw water 1 is provided with a sealed material so that it does not pass to the side.

In addition, a pumping means (not shown) for supplying water into the buoyancy control space 21 or discharging water stored in the buoyancy control space 21 is additionally provided so that the lifting and lowering of the rust wall 20 is controlled by buoyancy. desirable.

Here, the pumping means may include a suction line for sucking water and a discharge line for discharging water, and discharges the raw water 1 along the discharge line by sucking the raw water 1 through the suction line. I can make it.

In this case, the suction line and the discharge line are selectively connected to the inside of the buoyancy control space 21 so that the raw water 1 may be supplied to the inside or the raw water 1 inside may be discharged to the outside. That is, it is understood that the word selectively connected means that the suction line and the discharge line are connected opposite to each other when the raw water 1 is supplied to the buoyancy control space 21 and when the raw water 1 is discharged. This is desirable.

In detail, when supplying the raw water 1 to the buoyancy control space 21, the suction line of the pumping means is connected to suck the raw water 1 of the water source, and the discharge line is the buoyancy control space 21 ) Can be connected to the inside. Accordingly, the raw water 1 sucked into the pumping means is discharged to the buoyancy control space 21 through the discharge line and is stored in the buoyancy control space 21. At this time, since the amount of the raw water 1 stored in the buoyancy control space 21 increases, the buoyancy of the rust end wall 20 decreases, so it moves downward and the depth of immersion increases.

Meanwhile, when the raw water 1 stored in the buoyancy control space 21 is discharged, the suction line of the pumping means is connected to the inside of the buoyancy control space 21, and the discharge line may be connected to the outside. Accordingly, the raw water 1 inside the buoyancy control space 21 is sucked by the suction line and discharged to the outside through the discharge line. At this time, since the weight of the rust end wall 20 decreases and the buoyancy is increased, it is moved upward and the height at which it is floated above the water surface is increased.

Here, the pumping means may be driven by changing the rotation direction of the motor without changing the connection between the suction line and the discharge line according to the supply and discharge directions of the raw water 1. That is, by changing the rotation direction of the motor, the existing suction line acts as the discharge line, and the existing discharge line acts as the suction line to supply and discharge the raw water 1 through one connection line. I can.

In addition, the pumping means is installed on one side of the lifting support file 10 and provided in a state connected to the buoyancy control space 21 and may be driven through valve control, or provided as a separate device to the buoyancy control space (21) It may be connected and driven only when the water storage quantity is adjusted.

In this way, by simply changing the storage amount of the raw water 1 stored in the buoyancy control space 21 by the pumping means, the depth of immersion of the rust end wall 20 can be adjusted. Because it is easy, operation convenience can be remarkably improved.

On the other hand, the rust end wall 20 is covered with an upper end, and a through hole communicating with the buoyancy control space 21 is formed on one side so that the pumping means passes through the through hole and is connected to the buoyancy control space 21. May be. At this time, the upper end of the rust end wall 20 may be covered with a separate cover member, or the upper ends of the inner blocking film 22 and the outer blocking film 23 may be integrally connected and covered.

Accordingly, since the buoyancy control space 21 except for the portion in which the through hole is formed is blocked from the external space, rainwater enters the interior during a rainfall or the external raw water 1 is introduced by waves, preventing the problem of increasing the amount of water stored. Can be. In other words, since water other than the supply of raw water (1) by the pumping means is prevented from changing, the amount of water stored in the buoyancy control space (21) is prevented, the predetermined depth of immersion of the rust end wall (20) is stably maintained. Can be.

On the other hand, referring to FIGS. 3 to 4, the screen apparatus 100 for a green plant for a water intake tower may be driven in consideration of occurrence of a green algae phenomenon.

At this time, the green algae phenomenon refers to a phenomenon in which the color of water changes to dark green when blue-green algae grow excessively in a river, lake, or reservoir used as a water source and multiply. In addition, the blue-green algae grows to the maximum at a high temperature of 20 to 30°C, and the green algae phenomenon occurs mainly in summer, and because of photosynthesis, the blue-green algae grows excessively on the sunny surface and forms a band-shaped green algae layer (3) on the surface. Can be formed.

In detail, in a river or lake where the water depth is deep and the flow is stagnant in summer, the water layer is separated due to the difference in water density, resulting in a stratification phenomenon in which the water does not move vertically, the temperature of the water surface is further increased, and a favorable condition for the growth of blue-green algae is formed. . Accordingly, the blue-green algae proliferate in large quantities, and the green algae layer 3 having a thickness of about 3 to 4 m from the water surface may be formed.

Here, it is preferable that the rust end wall 20 is disposed to cover the water intake port 200a installed at a height where the rust algae layer 3 is formed. That is, it is preferable to understand that the rust end wall 20 is a device that blocks the flow of water to prevent the algae forming the green algae layer 3 from flowing into the water intake port 200a along the horizontal flow of water. On the other hand, the rust barrier 20 is not limited to blocking only algae flowing into the water intake port 200a, and includes blocking various pollutants flowing through the water surface due to a water pollution accident.

In detail, the rust end wall 20 increases the amount of water inside the buoyancy control space 21 through the pumping means to block the water intake port 200a from the green algae layer 3, so that the lower part 24 is the water intake port. The depth of immersion may be adjusted to be disposed lower than the lowermost end portion 200c of 200a. That is, when the amount of water stored in the buoyancy control space 21 increases, the buoyancy space into which air is introduced decreases, the buoyancy decreases by the load of the stored water, and the sinking depth increases.

Accordingly, the water flowing through the water layer from the water surface to the lower end of the rust end wall 20 hits the rust end wall 20 and is blocked from linear movement and flows along the outer periphery of the rust end wall 20. Will go.

On the other hand, the water below the rust end wall 20 flows toward the water intake tower 200 along a horizontal flow path, rises upward between the inner surface of the rust end wall 20 and the outer surface of the water intake tower 200, so that the water intake port 200a It can be collected along the water intake passage (f) flowing into ).

Here, the green algae end wall 20 is preferably submerged below the green algae layer 3 formed to a thickness of about 3 to 4 m so as to stably cover the intake port 200a from the green algae layer 3 It can be formed with an immersion depth of about 5m. Accordingly, since deep water of about 5 to 6 m can be taken along the intake passage f, algae or other pollutants may be prevented from flowing into the intake port 200a. Of course, the rust end wall 20 may be formed to have a longer or shorter length in consideration of the height of the water intake port 200a or the thickness of the green algae layer 3.

In addition, a bird detection sensor 31 for detecting the concentration of algae may be provided at one side of the outer surface of the lower end 24 of the rust-even end wall 20. In addition, a signal communication unit 32 that transmits a detection signal to the server system 33 of the water intake tower manager according to the measurement data transmitted from the bird detection sensor 31 at the upper end of one of the plurality of lifting support files 10 It may be further provided.

At this time, the bird detection sensor 31 and the signal communication unit 32 may be connected wirelessly or wired, and the signal communication unit 32 preferably transmits and receives a signal through wireless communication with the server system 33. .

In detail, the algae detection sensor 31 is installed on the lower end 24 of the rust end wall 20 and can detect the algae concentration at the lower end 24 side. Here, the algae is preferably understood as a device for measuring the concentration of blue-green algae that causes green algae in summer.

In this case, when the algae concentration is detected to be higher than a preset concentration, it may be determined that the green algae layer 3 is formed above the immersion depth of the rust end wall 20. Accordingly, the signal communication unit 32 receives the detection signal from the bird detection sensor 31 and transmits the detection signal to the server system 33 of the manager of the water intake tower 200.

In addition, when receiving the detection signal, the manager of the water intake tower 200 drives the pumping means to suck the raw water 1 and supply the raw water 1 to the inside of the buoyancy control space 21. The depth of immersion can be adjusted to further submerge downward.

Meanwhile, a control unit may be further provided to receive a detection signal from the signal communication unit 32, and to be connected to the pumping unit to control the suction or discharge direction of the pumping unit and open/close power. Here, it is preferable to understand that the pumping means is provided on one side of the rust end wall 20 so that the buoyancy control space 21 and the raw water 1 outside and the suction and discharge lines are always connected.

That is, when the algae concentration is detected above a preset concentration, the signal communication unit 32 transmits a detection signal to the control unit. In addition, the control unit applies power to the pumping means and opens a suction line connected to the outer raw water 1 and a discharge line connected to an inner side of the buoyancy control space 21, so that the raw water 1 can be moved. .

Here, the pumping means is powered by the drive of the control unit and the suction and discharge directions of the raw water 1 can be adjusted, so that the manager of the water intake tower 200 does not manually drive the pumping means in real time. Can be manipulated.

In addition, the algae detection sensor 31 may be provided with a fluorescence meter or the like that measures the amount of light emitted by the algae absorbing energy from light. In addition, the preset concentration may be set based on the number of blue-green algae cells measured when it is determined that the green algae phenomenon has occurred.

In addition, the Ministry of Environment operates a three-stage tide alarm system of interest, alertness, and algae generation to protect the water supply source, and when it is determined as the level of interest, the installation of an algae blocking device in the intake port 200a is prescribed. Accordingly, the preset concentration may be set to correspond to 1,000 cells/ml by applying the standard for the number of cells of the blue-green algae corresponding to the step of interest.

In addition, the algae detection sensor 31, especially in the early summer in the rainy season inflow of nutrients excessive inflow of nutrients and high temperature conditions are formed, so that a large amount of algae proliferate near the water intake tower 200, and the green algae layer 3 Can be detected immediately. Therefore, by covering the intake port 200a from the green algae layer 3 according to a control signal, it is possible to quickly block the flow of algae together with the raw water 1 into the intake port 200a, thereby improving the speed of driving. Can be.

On the other hand, the algae detection sensor 31 may be replaced with a water level detection sensor. The water level sensor may be provided on one side of the lifting support pile 10 to detect the water level of the water source, and may be provided in plural and installed at different heights.

In detail, when the water level of the water source rapidly increases during a summer rainfall, the lower end 24 of the rust end wall 20 is moved upward from the lowermost end 200c of the water intake 200a to cover the water intake 200a. It may not be possible. At this time, the signal communication unit 32 transmits a detection signal to the server system 33 of the manager of the water intake tower 200 when the water level measurement data received from the water level detection sensor detects that the water level of the water source is above a predetermined level. In addition, the manager of the water intake tower 300 may adjust the depth of submersion of the rust end wall 20 according to the detection signal.

Accordingly, the manager of the water intake tower 200 increases the amount of water stored in the buoyancy control space 21 so as to prevent the inflow of blue-green algae or contaminants on the surface into the water intake port 200a to increase the depth of flooding of the rust end wall 20 Can be adjusted quickly.

On the other hand, in the dry season when the green algae does not occur and the water level of the water source is low, such as in winter, the water intake of the raw water 1 from the upper side is required, so the rust end wall 20 is moved upward so that the water intake port 200a is It is preferably adjusted to be open.

In detail, when the water stored in the buoyancy control space 21 is discharged to the outside by the pumping means, the space through which air is introduced into the buoyancy control space 21 is increased. That is, since the buoyancy space inside the buoyancy control space 21 increases and the buoyancy increases, the depth of submersion decreases as the rust end wall 20 rises and descends, and the interval to be floated above the water surface increases.

Accordingly, the lower end 24 of the rust end wall 20 is disposed above the uppermost end 200b of the water intake port 200a, so that the side direction of the intake port 200a is opened. Accordingly, the raw water 1 flowing through the height of the water intake port 200a may flow into the intake port 200a as it is along the horizontal flow path of the water source.

At this time, the rust end wall 20 is not floated so that the lower end 24 is necessarily disposed above the uppermost end 200b of the intake port 200a, and may be disposed to cover a part of the upper end of the intake port 200a. May be.

In this way, as the rust end wall 20 surrounds the water intake tower 200 and selectively covers the water intake port 200a, the flow path of the raw water 1 is changed, Even contaminants may be blocked without passing through the rust barrier 20. Accordingly, since the uncontaminated raw water 1 can be selectively taken by adjusting the depth of immersion of the rust end wall 20, the inflow of green algae is minimized, and the water quality of the raw water 1 to be taken in is improved. Economics can improve as costs are saved.

In addition, the rust-even end wall 20 increases the depth of submersion so that it is possible to prepare for the occurrence of green algae in summer, and when the water level decreases, the depth of submersion decreases so that the raw water 1 on the surface side can be ingested, thereby reducing the water level in winter. It can also respond. In this way, the applicability of the device can be improved because the depth of immersion of the rust end wall 20 can be flexibly adjusted by a change in buoyancy according to the amount of water stored in the buoyancy control space 21 according to seasonal changes.
