BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric water circulation device for preventing an electric cable and an anchor chain from being twisted, and more particularly to an electric water circulation device using an electric water circulation device having an impeller, To an electric water circulation device capable of preventing a cable and an anchor chain from being twisted.

There are about 18,000 lakes in Korea, and there are about 14500 lakes with less than 10m of open water and less than 1 million ㎥ of fresh water. Most of these lakes are exposed to soil and foreign matter due to the influx of runoff during rainfall, and water quality tends to deteriorate in urban or nearby areas. In addition, due to the influx of polluted river water, most of these lakes are accelerating eutrophication, and are suffering from pollution and algal bloom. In addition, reservoirs that have been used as agricultural water in recent years, including artificially constructed reservoirs in cities, have been newly developed as adoption lakes by the development of new cities or the expansion of urban areas and the conversion of reservoirs with lower utilization rates as agriculture water sources. Since these hydrophilic lakes are low in water depth, the green tides tend to be deepened by the dust supplied from the air even in the absence of a particular influent pollutant source, and they are aesthetically affected by the contamination depending on the bottom surface condition of the lake. Therefore, it is essential to apply the water quality improvement technology to control the microfluidic substances and the algae phenomenon which are common problems of these lakes. However, the water circulation system developed in the past has a large volume of circulating water of 38 tons per minute. In the case of such a large facility, it is not suitable for the application of small lake such as ecological river, park pond, golf course pond, wastewater treatment plant and water treatment plant in Korea due to excessive cost and inefficiency of initial installation and maintenance. Furthermore, the conventional water circulation apparatus is structurally designed to be applied to the stagnant water such as a lake dam, and can not be used in a place where the wind speed is high or the wave is high.

In order to solve the above-mentioned conventional problems, Korean Patent Registration No. 10-1207955 has proposed a solar water circulation apparatus improved in internal wave. This is a solar water circulation apparatus provided with a solar panel capable of charging electric power using solar light and having a motor driven by the power charged by the solar panel, ; An upper pedestal for seating the motor; An impeller connected to the motor by a shaft at the lower end of the upper pedestal; A distribution plate for allowing the water introduced into the inlet by the impeller to spread from the upper side to the lower side; An extension support connected to the upper pedestal; A connecting portion connecting the end of the extension support to the buoyancy member, the connection portion being formed of a chain or stretchable material to improve the wave resistance by wave or wave; And a length adjuster formed between one end of the upper pedestal and the intermediate portion of the extended pedestal to adjust the length between the upper pedestal and the middle portion of the extended pedestal.

Such a conventional water circulation apparatus has been known as a device which does not require consumption of external electric power by using sunlight and has little maintenance cost and is simple in structure and easy to disassemble when necessary.

However, in the water circulation device, the water circulation device rotates by the thrust of the water discharged from the impeller, and the buoyant material installed in the water circulation device rotates, so that the chain connected with the buoyancy material is twisted in water. When a certain level is twisted, the length of the chain is decreased accordingly, and when the anchor is floated and the position of the apparatus is largely deviated or the anchor is deeply fixed to the low-grade layer, the water circulation device is partially submerged by tension, A trouble occurs. In addition, when the connection part between the buoyant material and the device is broken, there is a serious problem that the water circulating device floating on the water surface by the buoyant material is completely flooded.

In addition, when an electric water circulation device is used by connecting commercial electric power rather than a solar water circulation device, the electric water circulation device drives the motor connected with the electric cable to operate the impeller. Here, the electric water circulation device introduces the lower layer water at the lower end due to the pressure difference generated by the driving of the impeller. Then, the water is naturally discharged to the upper layer water through the distribution plate at the upper part, and the lower layer water is repeatedly circulated to the upper layer water, thereby realizing efficient water circulation. However, thrust is generated in the opposite direction of the water discharged by the driven impeller rotation, and the water circulation device rotates. When the electric cable connected to the motor and the anchor chain connected to the buoyant material are twisted and the electric cable and the anchor chain are twisted to a certain level or more, the cable is damaged and the power supply is interrupted and the water circulation device can not be operated. . Also, cable and anchor chains can become tangled and shortened in length, leading to catastrophic accidents that cause water circulation to overturn or sink.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electric water circulation apparatus for preventing twisting of an electric cable and an anchor chain according to an embodiment of the present invention will be described in detail with reference to the drawings.

2 is a perspective view of an electric water circulation apparatus according to the present invention.

2, the electric water circulation apparatus according to the present invention comprises a main unit 100, a driving unit 200, and a distribution plate 300, and will be described below.

The main unit 100 of the present invention includes an underwater pipe 110 located in a water body and a plurality of buoyant members 130 provided outside the underwater pipe 110 and an anchor connecting the ends of the buoyant 130 to the anchor, A chain 150 is provided.

The water tube 110 may be formed in a cylindrical shape and the water inlet 111 located at the lower end of the water tube 110 and the distribution plate 300 located at the upper end may be installed in the water of the water, And is used as a discharge passage. The water is circulated by repeating the discharge of the water of the lower layer water flowing through the underwater pipe 110 to the upper layer water.

 Preferably, the inlet 111 is positioned in a lower layer of the body of water to allow the lower layer water of the water body to enter the inlet 111 of the underwater tube 110. Since the depth of the lower layer of the water body varies depending on the position, it is preferable that the length of the underwater pipe 110 varies according to the water depth. Therefore, the underwater pipe 110 may be formed as a corrugated pipe so that the length thereof may be changed.

The buoyancy material 130 is installed outside the underwater pipe 110 and a plurality of the buoyancy materials 130 are connected to float the water circulation device. In addition, the buoyancy material 130 is made of a material that can be floated in water in an empty shape. The buoyancy member 130 is installed to be connected to the dish and the arm connecting the distribution dish 300. Here, the arm may have the shape of a long connecting link for installing the buoyancy material 130 at a wide radius outside the underwater pipe 110.

The anchor chain 150 connects the anchor with the buoyancy material 130 so that the water circulation device can moor at a desired position. The anchor chain 150 is made of a material resistant to the flow of water and resistant to corrosion.

The driving unit 200 of the present invention includes an impeller 210 disposed at an upper end of the water tube 110 and circulating water to discharge the inflow water, a motor 230 driving the impeller 210, 230 and an electric cable 250 connected thereto.

The motor 230 is provided on an upper support 231 at an upper end of the underwater pipe 110 and is connected to the electric cable 250 to rotate the impeller 210 with electric power.

The impeller 210 is provided between the upper pedestal 231 and the underwater pipe 110 so that water moving upward in a predetermined direction can be easily discharged through the distribution plate 300. The impeller 210 is composed of a plurality of rotating blades with a driving shaft as a center, and is connected to the motor 230 and can be rotated by receiving power.

1 is an exemplary view showing a twisted state of an electric cable and an anchor chain of a conventional electric water circulation apparatus.

1, thrust is generated in the direction opposite to the water discharged through the distribution dish 300 by the rotation of the impeller 210 to rotate the water circulation device, and the electric cable 250 and the anchor chain (150) is twisted.

3 is a view provided to explain the principle of rotation of a water circulation apparatus of the prior art. And FIG. 5 is a detailed view of the vertical impeller of the present invention.

3 and 5, when the vertical impeller 211 rotates in the clockwise direction, the water discharged by the rotation of the vertical impeller 211 flows in the direction opposite to the rotating direction through the distribution dish 300 . Therefore, the water discharged from the distribution dish 300 has an angle of? In the direction opposite to the rotation of the vertical impeller 211 and is discharged in the A direction. At this time, a reaction force and a thrust against the water flow acceleration force generated by the rotation of the vertical direction impeller 211 are generated. Here, the thrust is generated in the A direction of the water discharged from the distribution dish 300 and in the B direction of the beta angle, which is the circumferential direction in the rotating direction of the vertical direction impeller 211. As a result, the water circulation device is rotated by the thrust, and the electric cable and the anchor chain connected to the water circulation device are twisted. The vertical direction impeller 211 generates angular velocity by rotation, and the direction of rotation is changed according to the shape and angular velocity.

4 is a view for explaining the principle of rotation prevention of a water circulation apparatus equipped with a guide vane of the present invention.

As shown in FIG. 4, the guide vane 310 is installed in the distribution plate 300 to eliminate thrust which is a cause of rotation of the water circulation apparatus shown in FIG.

Here, the thrust is generated by the impeller (210, 210) having a rotational force in the distribution dish (300) and water is discharged. Therefore, when the water is discharged from the distribution dish (300) The guide vane 310 is installed.

The guide vanes 310 are installed such that a plurality of thin guide plates are vertically installed on the outer circumferential surface of the distribution plate 300 at an angle. And each of the guide vanes 310 forms an angle of 90 [deg.] With respect to the circumference. As a result, when the water having rotational force is discharged from the distribution dish 300 by the rotation of the impeller (FIGS. 2 and 210), the rotational force is canceled by the guide vane 310 and the guide vane 310 is guided And is discharged in the same direction C as the direction of the discharge. Here, the C direction is like a radial shape starting from the distribution dish 300 and extending from one point in the center in the direction perpendicular to the circumference. The guide vane 310 installed in the distribution plate 300 can prevent the water circulation device from rotating.

In order to prevent rotation of the water circulation device in the distribution plate 300 of the present invention, a plurality of guide vanes 310 are formed at regular intervals along the outer circumferential surface.

This is because the main vane 310, A plurality of the guide vanes 310 are arranged on the outer circumferential surface of the distribution dish 300 to eliminate the thrust for rotating the dispenser 100. Here, one guide vane 310 is installed so that a plurality of thin guide plates are vertically arranged along the outer circumferential surface of the distribution plate 300 at an angle. Each of the guide vanes 310 has an angle of 90 ° to contact the circumference of the guide vane 310 and water having a rotational force due to the rotation of the vertical impeller 211 is discharged through the guide vane 310 and is discharged in the same direction as the guide vane 310 guides. This makes it possible to prevent the water circulation device from rotating.
