Water Purification System of River Using Waterside Plants {SYSTEM FOR PURIFYING QUALITY OF WATER OF RIVER USING AQUATIC PLANT}

The present invention relates to a water purification system for rivers using waterside plants, and more particularly, to a water purification system for purifying water quality of rivers using waterside plants and blocking dirt from upstream. will be.

As awareness of the natural environment has gradually spread, the problem of pollution to drinking water, an absolute factor for human survival, has become a serious problem. Sources of contaminating rivers and rivers, which are drinking water sources, are contaminants, live sewage, surplus fertilizers and pesticides from the upstream, which often cause eutrophication of the rivers. Upstream dirt flows down like rivers and contaminates rivers and rivers.

As is well known, eutrophication refers to a phenomenon in which abnormal growth of red tide, plankton, etc. occurs due to the increase in nutrients in rivers due to decomposition of organic matter by microorganisms. Since eutrophication destroys ecosystems in rivers and kills all living organisms in freshwater, various measures to prevent eutrophication have been attempted in the past, and one of them is a method of absorbing and removing nutrients using water plants. That is, nutrients are absorbed through the roots of aquatic plants to prevent eutrophication, and such water plants are reeds, moon roots, silver grasses, irises, strings, and buds.

By the way, it is possible to plant the riparian plant on the outermost edge of the low-depth stream, but cannot plant on the inner edge deeper than the outermost edge. Therefore, in order to plant the riparian plants on the inner edge of the river, artificial buoyancy floating on the surface by buoyancy is required.

Various artificial defaults have also been presented in the past, and one of them will be described as follows. It is a structure in which the anchor is connected to the float by a rope in order to place the fibrous mat on which the water vegetation can float on the float floating on the surface of the water.

By the way, in the conventional artificial default as described above, the floating body is supported only by the anchor of a predetermined weight or more, mostly one anchor. More specifically, the conventional structure is such that the floating body is not moved only by the anchor placed on the bottom of the river.

Artificial bankruptcy of this structure is not a problem when there is no water flow or a low flow rate, such as freshwater lakes. However, when the flow velocity is high like a river, and the flow rate is such that the anchor moves, the situation changes. In particular, in the case of Korea, heavy rain falls during the rainy season, which causes a rapid increase in the flow velocity of the river. In this situation, floats supported only by anchors are often lost due to very high flow rates.

In addition, the filth floated from the upstream during the flooding will remain floating along the surface of the river or river, and in the past, enormous manpower, time, and money had to be invested to remove the filth. The reason for this is that conventionally, there was no way to collect dirt on the riverside, so the worker had to go directly to the center of the river or river to carry out work.

In particular, if the soil introduced from the upstream in the river or river where the artificial bank using the waterfront plant is placed as it is, there is a high possibility that the soil may penetrate into the artificial bank. Sewage penetrated into the artificial islands will interfere with the growth of the water plants and cause a situation in which water purification of the water plants will be degraded.

Accordingly, the present invention has been made to solve the above-described problems, the water quality of the river using the waterfront plants that can prevent the loss of artificial buoys by maintaining the artificial buoys do not deviate from the predetermined position even by the rapid flow rate The purpose is to provide a purification system.

Another object of the present invention is to provide a water purification system for rivers using waterfront plants that can prevent the inflow of dirt introduced from upstream to the riverside and prevent penetration into artificial banks.

In order to achieve the above object, the water purification system according to the present invention has the following configuration.

A plurality of artificial buoys are arranged to float along the water surface of the river. On the upstream side of the artificial buoy, a water remedy for preventing the infiltration of dirt into the artificial buoy is disposed.

The composition of the artificial default is as follows. Floating mats floating on the water surface of the river are placed on the mesh mats that make the water plants grow. The net mat is fitted with a plurality of pots, each of which is filled with soil for planting water plants. The roots of the riparian plants grow to penetrate the pots and mesh mats and are placed underwater to absorb nutrients generated in the stream. The entire outline of the float is surrounded by a support frame, which is firmly fixed to the support frame. Several rings are installed on the outer surface of the support frame. One end of the wire rope is connected to the loop, and the other end of the wire rope is connected to the anchor block. Anchor blocks are embedded in the bottom of the stream and fixed.

The composition of the award measures is as follows. At the bottom of the stream is fixed at least one of the lower ends of the cylinder. The upper end of the cylinder is opened, and the lower end of the rod is fitted into the upper end of the cylinder so as to be liftable. At the top of the rod is installed a barrier member to block the flow of dirt while floating along the water surface of the river. The barrier member is disposed perpendicular to the flow direction of the river. In particular, the barrier member is preferably disposed to be inclined at a predetermined acute angle with respect to the river flow direction so that the blocked dirt is guided to the riverside.

According to the configuration of the present invention described above, since the floating body is supported by the support frame, and the support frame is supported by the anchor block fixed to the bottom of the river, the floating body can be maintained at a predetermined position without being lost by the high flow rate. Loss of artificial defaults is prevented. In addition, the water measures are disposed upstream of the artificial buoy, thereby making it easy to remove the dirt from the upstream, and also prevent the dirt from penetrating into the artificial buoy and hindering the action of the waterside plants.

As shown in FIG. 1, the water purification system of a river according to the present invention includes a plurality of artificial buoys 1 floating along the water surface of the river and disposed upstream of the artificial buoy 1 to block dirt. It consists of the water measures (2).

First, the configuration of the artificial incubator 1 will be described in detail. In Figures 2 and 3, several support frames 10 (five in this embodiment) in a rectangular frame shape are arranged laterally and connected to each other. Each support frame 10 has four anchor blocks 20 connected to the wire rope 21 at each corner. In particular, the support frame 10 on both sides of the outer two anchor blocks 20 are further connected to the outer side to strengthen the bearing force. As shown in detail in FIG. 3, the anchor block 20 is not simply placed on the bottom of the river but is embedded in the bottom and fixed.

Meanwhile, although not shown in FIG. 2, four floats are arranged in each support frame 10, and the arrangement structure is illustrated in FIG. 4 in detail. As shown, the partition member 11 in the support frame 10 is arranged crosswise, so that the support frame 10 is divided into four regions. Four floating bodies 30 are arranged in each region, and are firmly fixed to the support frame 10 and the partition member 11. The partition member 11 may be configured to cross the two crosswise, but in the present embodiment, as shown in detail in Figure 5, by using the joint 12 to the center portion that intersects the four and the connection point of each other You can also connect. In other words, by using the joints 12 having four openings, the four partition members 11 can be fitted into each of the openings of the joints 12 by interference fit.

As shown in Figs. 6A and 6B, the floating body 30 has several long rectangular members arranged at regular intervals, both ends of which are fixed to two rectangular members, and at the bottom four rectangular members are rhombic. It is arranged as a structure. On the floating body 30 having such a shape, as shown in more detail in FIG. 7, a mesh mat 31 for sliding the waterside plants is mounted and fixed. Several ports 32 are fitted to the mesh mat 31, with each port 32 being located between the lattice structures of the float 30. Accordingly, the waterside plants planted in the soil filled in the pot 32 can grow through the mesh mat 31 and the float 30. The material of the floating body 30 employed in this embodiment is a lightweight plastic.

In the present embodiment, the support frame 10 is divided into four regions by the partition member 11, and four floating bodies 30 are arranged in each region, but the configuration is the same as in the present embodiment. There is no need to do it. As an example, the support frame 10 and the floating body 30 may be manufactured to have substantially the same size, and may be configured one by one, and in addition to the four in the supporting frame 10, several floating bodies 30 may be configured. Of course.

The key elements of the present invention are a support frame 10 and an anchor block 20 for supporting the floating body 30 so as not to be lost by a rapid flow rate, and only one support frame 10 is shown in FIG. The detailed structure of the support frame 10 is shown in FIGS. 9 to 11.

As shown, the support frame 10 is composed of an annular pipe 13 made of plastic and a square pipe 14 made of stainless steel. The annular pipe 13 is arranged inside, and the square pipe 14 is arranged outside. Therefore, the outside of the floating body 30 is fixed to the annular pipe 13, it is preferable to use a bolt and nut fastening method as a fixing method. In order for the annular pipe 13 to be buoyant, it is preferable to fill the interior thereof with a foamable filling.

The annular pipe 13 and the rectangular pipe 14 are connected by a U-shaped band 16. As shown in Fig. 8, a total of eight points are connected to the U-shaped band 16 for every two corner portions of the support frame 10, and the detailed structure thereof is shown in Figs. As shown, the bottom surface of the L-shaped bracket 17 is welded to each of the upper and lower surfaces of the square pipe 14, and the welding nut 18 is welded to the side of each bracket 17. The U-shaped band 16 surrounds the inner circumferential half of the annular pipe 13, and the bolt 19 formed at both ends thereof is fastened to the welding nut 18, whereby the annular pipe 13 and the rectangular pipe 14 are formed. It will be fixed firmly. On the other hand, in order to prevent the U-shaped band 16 from being worn in frictional contact with the annular pipe 13, the cushioning rubber 16a is interposed between the contact surface of the U-shaped band 16 and the annular pipe 13. desirable.

The support frame 10 configured as described above is connected to the anchor block 20 through the wire rope 21 as described above. For this, as shown in FIG. 9, the outer surface of the square pipe 14 is provided. More specifically, the ring 15 is installed at each portion where the U-shaped band 16 is located. Thus, the ring 15 is a total of eight per one support frame 10, like the U-shaped band 16, the anchor block 20 is not connected to all the ring (15).

That is, as shown in Figure 4, since the support frame 10 is not one, but several, the loops of each support frame 10 disposed on both sides based on Figure 3 adjacent to each other are different wire rope 21 By being connected to each other, each support frame 10 is connected to one. Therefore, the wire rope 21 connected to the anchor block 20 is connected to the remaining rings arranged in front and rear with reference to FIG. 4.

As described above, the anchor block 20 is embedded in the bottom of the river, and the material of the anchor block 20 is concrete in this embodiment. On the upper surface of the concrete anchor block 20, as shown in Figure 13, a ring 22 for connecting the wire rope 21 is provided.

Artificial banks having the above configuration are not to be lost even by the rapid flow rate. By the way, the water level of the river is not always constant, and varies greatly with the season. In particular, depending on the rainy season and the dry season, the level of the river will show a significant difference.

Therefore, the float 30 must float along the fluctuating water surface, and the vertical movement range of the float 30 is determined by the length of the wire rope 21 connected to the anchor block 20 according to the present invention. . Therefore, if the length of the wire rope 21 is sufficiently long, it may be said that the floating body 30 does not interfere with floating along the surface of the water.

However, the problem to be solved by the present invention is to prevent the artificial buoys from moving by the stream flow, if the length of the wire rope 21 is too long, as described above, the artificial buoys will not be lost depending on the flow of water The range of movement becomes too large.

In order to prevent this, it is preferable that a mooring device for mooring the artificial buoy at the installation position is provided in the artificial buoy according to the present invention, and the mooring device is shown in FIG.

First, it should be noted that the mooring device shown in FIG. 14 is not well developed by the applicant but is a well known technique. Therefore, only the outline will be described.

As shown, the floating holes 24 are disposed one by one on both sides of the artificial default. The wire rope 21 fixed to the artificial bank is movably connected to the left floating hole 24. The wire rope 21 is divided into two strands and fixed to each of the two anchor blocks 20 embedded in the bottom of the river. On the other hand, the floating hole 23 is also provided in each of the two wire rope 21 branched. Of course, the wire rope 21 is movably connected to each floating hole (23).

Similar to the left side, the right floating hole 24 is connected to the two anchor blocks 20 by branching in two strands, but is fixed as shown in the left side or each is wound on a ring so that the right floating hole 24 is formed. It is wound up by the buoy 25 which floats along the water surface.

Thus, the portion of the wire rope 21 wound around the buoy 25 is released as the artificial buoy rises along the water surface, thereby enabling floating of the artificial buoy. As a result, the entire length of the left wire rope 21 in FIG. 14 limits the vertical movement range of the artificial failure. That is, the mooring device is a device that adjusts the length of the wire rope 21 according to the water level of the river, so that the artificial buoy is limited to move only up and down without greatly flowing from side to side along the water surface at the installation position.

Next, the constitution of the water remedies is explained. As shown in Fig. 15 and 16, the lower end of the cylinder 40 is fixed to the bottom of the river. The lower end of the cylinder 40 may be simply driven by fixing as described above, but in order to further strengthen the fixing force, the lower end of the cylinder 40 is fixed to the anchor block 41 of concrete, and the anchor block 41 is fixed. It is more preferable to put the in the bottom of the river.

The upper end of the cylinder 40 is opened, and the lower end of the rod 42 is fitted into the upper end of the cylinder 40 so as to be liftable. A barrier member 50 for blocking dirt while floating along the water surface of the river is installed at the top of the rod 42. On the other hand, the outer circumferential surface of the cylinder 40, it is preferable that a plurality of entrance holes 43 are formed in order to facilitate the entrance and exit of water.

Here, as shown in Figure 16, the railing member 50 is a shape and a material that can block the dirt floating upstream, in this embodiment is a cylindrical log, in particular arranged to be substantially perpendicular to the flow direction of the river water. Should be. However, the barrier member 50 is not limited to the cylindrical log as described above, and may be replaced with another material that is floatable on the surface of the water, for example, a plastic pipe filled with an expandable filler therein.

Further, as shown in FIG. 1, the barrier member 50 is more preferably disposed at an inclination angle of about 45 ° with respect to the flow direction of the river. More specifically, the dirt is blocked by the railing member 50, which is intended for water barrier, and if the railing member 50 is simply arranged orthogonal to the direction of the river flow, the dirt is in the blocked position. Therefore, as described above, if the railing member 50 is disposed to be inclined with respect to the river flow direction, since the dirt is guided to the riverside by the river flow, the operator can remove the dirt from the riverside more easily.

As described above, according to the present invention, the water quality of the river is purified by the waterfront plants of the artificial banks, and in particular, the water measures disposed upstream of the artificial banks prevent the infiltration of dirt into the artificial banks. Water purification will not be interrupted by dirt.

In addition, since the floating body of the artificial buoy is supported by the support frame, and the support frame is supported by the anchor block fixed to the bottom of the river, the situation in which the artificial buoy is lost due to the rapid flow rate is prevented.

In addition, it is possible to more easily remove the dirt floated from the upstream by the water measures, and in particular, it is possible to collect and remove the dirt from the riverside side by the obliquely arranged railing member.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
