Description

Fluidization Apparatus for River or Lake and Methods Using The Same}

The present invention relates to a device for fluidizing river or lake water and a fluidization method using the same, and more particularly, by stirring or inducing a flow of stagnant water, an effect of reducing algae can be expected, and actively responding to external environmental changes such as precipitation or wind. It relates to a river water or lake water fluidization device capable of minimizing loss or maintenance cost of the device and a fluidization method using the same.

Nutrients such as nitrogen and phosphorus flow into the water system, and due to the temperature rise caused by global warming, algal blooms frequently occur in various water systems including water sources every year. Green algae refers to a phenomenon in which the color of water appears green, and is the result of non-ideal growth of blue-green algae. This green algae phenomenon not only has an aesthetic effect, but also can cause health harm because blue-green algae produce a toxin called microcystin, so it is necessary to suppress the occurrence of green algae in river water or lake water used as source water as much as possible.

On the other hand, in a stagnant area where there is little flow of water in a river or lake, for example, inducing water flow near the edge to minimize the proliferation of algae, and to supply dissolved oxygen, an aberration wheel is installed and operated.

For example, it is common to connect one side to the aberration and fix the other side to an underwater anchor or land structure so that the aberration is not lost using a pipe or rope.

In this case, some degree of algae reduction effect can be expected by stirring or inducing water flow through the rotational motion of the aberration, but in this case, the aberration is lost due to the inability to cope with external environmental changes such as precipitation or wind, or the structure for fixing However, problems such as damage to the aberration occur.

It is located in a floating state in a water system such as a river or a lake and is intended to agitate water near the water surface or to give flow to stagnant water, the main buoyancy body ( 110), a rotary blade 120, a motor 130, and a fixed frame 150.

The main buoyancy body 110 having buoyancy such as a cylindrical tube or styrofoam having an empty inside with the outside sealed may be provided as a pair spaced apart at a predetermined distance for the stability of the disturbing member 100, but if necessary Accordingly, the number of main buoyancy bodies 110 can be changed.

A plurality of rotary blades 120 located in a state connected to the support shaft are for agitating water near the water surface, and these rotary blades 120 are driven by a motor 130.

Although not shown in the drawing, the motor 130 may be supplied with power from a power cable connected to the ground, or may be supplied with power through a known power supply means such as a rechargeable battery or solar power generation.

The fixing frame 150 made of a plurality of bar shapes is to firmly fix the main buoyancy body 110, the rotary blade 120, and the motor 130, and the connection frame 200 is Connected.

The support rope 400 for holding the disturbance member 100 more stably is connected to the fixed frame 150 on one side and to a fixing pin or structure (not shown) on the ground, and the support rope 400 is connected to both sides of the disturbance member. ) are connected. Although the drawing shows that the support rope 400 is two, it is obvious that this is only an example and can be changed as much as possible.

This is an enlarged view of the structure.

The disturbance member according to the present invention can move freely in the vertical direction (in the direction of the depth of the water) and in the left and right directions (in the direction of the surface of the water) when referring to the water surface, so it has excellent ability to cope with environmental changes and in addition, external pressure applied to the disturbance member It is possible to minimize the loss of the fluidization device such as breakage of the support 300 can be prevented.

As shown in FIGS. 3 and 4, one side of the fixed frame 150 and the first connection frame 210 is connected in a hinge structure, and the other side of the first connection frame 210 is the second connection frame 220 One side of is also preferably connected to the hinge structure.

Here, the hinge structure connecting the fixed frame 150 and the first connection frame 210 is a hinge structure in which the disturbance member 100 can move up and down near the water surface, and the first connection frame 210 and the second Even in the hinge structure connecting the connecting frames 220, the first connecting frame 210 is a hinge structure that can move up and down.

In addition, as shown in FIG. 5, the other side of the second connection frame 220 is coupled to the upper support 320 of the support 300 in a hinge structure. At this time, based on the support 300, the second connection frame 220 ) is preferably hinged so that it can move up and down.

When the connection structure of the fixed frame 150, the first connection frame 210, the second connection frame 220, and the upper support 320 is connected by the hinge structure as described above, even if the water level rises due to rain or the like It is easy to position the disturbing member 100 in a floating state while minimizing the load transferred to the support 300, and in addition, the disturbing member 100 can move freely along the vicinity of the water surface.

On the other hand, there may be a case where the first connection frame 210 is located near the surface of the water due to the lowering of the water level. It is good that the sieve 230 is additionally provided.

The material of the first connection frame 210 and the second connection frame 220 is not particularly limited, and for example, it may be a steel pipe with a hollow inside, and if the above movement can be implemented, the configuration related to the hinge is not particularly limited. don't

Next, the support 300 will be described in detail. 6 is a cross-sectional view of the support, and FIG. 7 is an exploded perspective view of the support.

The support 300 prevents the disturbance member 100 and the connection frame 200 from being lost, while further expanding the movement path of the disturbance member 100, that is, an area in which it can move along the vicinity of the water surface.

Specifically, the support 300 includes a lower support 310 fixed to the ground, an upper support 320 located above the lower support 310, and an upper support 320 clockwise or It includes a rotation adapter 330 enabling rotation in a counterclockwise direction.

First, the lower support 310 is described, having a predetermined length in the shape of a cylinder or a polygonal column, and is positioned in a state firmly fixed to the ground through a known fixing method such as anchor or concrete casting, and a rotation adapter 330 at the top. ) is formed with a flange so that it can be attached or detached.

The upper support 320 hinged with the aforementioned second connection frame 220 has a predetermined length and is located above the lower support 310 .

Meanwhile, as described above, the fixed frame 150 and the first connection frame 210, the first connection frame 210 and the second connection frame 220, and the second connection frame 220 and the upper support 320 Since the hinge structure that connects is connected to allow only vertical movement, the permissible radius of the disturbing member 100 is inevitably limited.

Accordingly, the rotation adapter 330 is configured to allow the upper support 310 to freely rotate clockwise or counterclockwise with respect to the ground, through which the second connection frame 220 and the first connection frame 210 and the permissible radius of the disturbing member 100 can be maximized.

The rotation adapter 330 includes a lower adapter 331 detachably coupled to the upper end of the lower support 310, an upper adapter 332 detachably coupled to the lower end of the upper support 320, a lower adapter 331 and an upper adapter. It includes a fastening member 333 for controlling attachment/detachment of 332, and a rotational friction reducing plate 334 provided between the lower adapter 331 and the upper adapter 332.

The lower adapter 331 has a cylindrical structure with an open top and an empty interior, and has one or more fastening holes 331' formed on the side so that the fastening member 333 can be inserted to a predetermined depth inside. A flange for fixing to the lower support 310 is provided.

The upper adapter 332 has a cylindrical shape that can be accommodated in the inner space of the lower adapter 331, and a first groove 332′ for accommodating one end of the fastening member 333 is provided along the circumference of the outer wall There is, and a flange is provided on top so that it can be fixed to the upper support (320).

The fastening member 333 is to prevent the upper adapter 332 from being separated when the upper adapter 332 is inserted into the lower adapter 331, and may be a bolt, but is not particularly limited.

That is, when the fastening member 333 is inserted to a predetermined depth through the fastening hole 331' of the lower adapter 331 in a state where the upper adapter 332 is accommodated in the inner space of the lower adapter 331, the fastening member 333 The end of the upper adapter 332 is positioned in the first groove portion 332', and thus the upper adapter 332 is prevented from being separated from the lower adapter 331. Of course, it is obvious that the end of the fastening member 333 should not come into close contact with the wall surface of the first groove 332′ of the upper adapter 332 so that the upper adapter 332 can rotate freely, and the upper adapter 332 To prevent the rotation of the end portion of the fastening member 333 and the first groove portion 332 'of the upper adapter 332 are in close contact with the wall surface.

Meanwhile, the upper adapter 332 rotates while being accommodated in the lower adapter 331. At this time, the contact area between the lower adapter 331 and the upper adapter 332, that is, the upper surface of the side wall of the lower adapter 331 and the upper adapter The inner bottom surface of the flange of 332 may be worn or damaged by repeated rotation, and thus maintenance costs such as replacing the rotary adapter 330 or polishing the damaged portion may occur.

The rotational friction reduction plate 334 positioned between the lower adapter 331 and the upper adapter 332 is configured to minimize maintenance costs and further induce the upper adapter 332 to rotate easily.

That is, the approximately donut-shaped plate-shaped rotation adapter 330 having a central hole through which the cylindrical portion of the upper adapter 332 can pass through is interposed between the lower adapter 331 and the upper adapter 332, resulting in damage such as abrasion. By repairing or replacing only the rotating adapter 330, maintenance is relatively easy and costs can be saved.

In particular, when one or more second grooves 334′ having one or more circular shapes hollowed out to a predetermined depth are provided on the upper or lower surface of the rotational friction reducing plate 334, or on both the upper and lower surfaces, the frictional force can be reduced and the upper adapter 332 Rotation is easier, and when grease is applied to the surface of the rotational friction reducing plate 334, its lifespan can be extended due to reduced frictional force.
