BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hydraulic power generation apparatus, and more particularly, to a hydraulic power generation apparatus that is installed on a pipeline on which water flow advances to produce electric energy.

Generally, hydroelectric power generation means a device for generating electric energy by driving a power generation device using potential energy or kinetic energy of flowing water according to the water level of the water.

Generally, these hydroelectric power plants produce electric energy by constructing a power plant in a position where a topographical large drop is formed in a river or a river. Recently, researches for producing electric energy using buoyancy in wave or water have been active .

Especially, recently, as the risk of environmental pollution due to nuclear power plant and thermal power plant is greatly increased, more attention is paid to the hydroelectric power generation method which does not cause environmental pollution.

However, since conventional hydropower generation has been mainly performed using a geographical condition or accompanied by a large-scale construction, power loss is caused because it is located at a remote place from a city where power demand is high and is generated, Since it was a large-scale power generation system through construction, it was very difficult to produce electric energy by providing power generation facilities at a private level.

In order to solve the above-mentioned problems, the present invention is to provide a hydraulic power generating apparatus capable of producing electric energy by using kinetic energy of a water current moving along a pipeline.

In order to attain the above object, the present invention provides a water treatment device comprising: a channel portion forming a channel through which a water flow passes, a shaft member fixed inside the channel portion and having a coil wound therein, A rotating member provided rotatably around the shaft member and having a permanent magnet disposed at a position opposite to the coil wound on the shaft, and a rotating member electrically connected to the coil to transmit electric energy generated from the coil And a power transmission unit provided outside the power transmission unit.

Here, the rotating member may include a body portion having a hollow in which the shaft member is received, and a wing portion formed in a spiral shape along an outer surface of the body portion.

The distance from the center of the shaft member to the outer diameter of the wing portion may be 0.75 times or more of the length of the channel portion.

In addition, it is also possible to provide a connection part on both sides of the conduit part in which an opening corresponding to an internal conduit of the conduit part is formed, and a support frame in which both ends of the shaft member are fixedly installed may be installed inside the connection part Do.

Here, the support frame may include a fastening portion provided at the center of the inner opening portion and fitted with the shaft member, and a support portion extending in the outer direction of the fastening portion to support the fastening portion and the shaft member, And the shaft member may be electrically connected to the power generating unit through the coupling unit and the support unit.

The conduit portion may be detachably installed in the connection portion, and the plurality of conduit portions may be connected through the connection portion.

At least one bearing may be provided between the shaft member and the rotary member.

Furthermore, the coil wound on the outer surface of the shaft member or the permanent magnet installed inside the rotating member may be coated with a waterproof material. Alternatively, the coil may be internally wound so as not to be exposed to the outer surface of the shaft member, or may be disposed inside the rotating member such that the permanent magnet is not exposed to the hollow inner wall of the rotating member. The watertight packing may be formed at a position adjacent to the shaft member or the support frame so as to prevent the flow of water into the hollow inside the both ends of the rotary member.

According to the present invention, it is possible to utilize a pipeline such as a drain pipe or a water supply pipe disposed at an adjacent position, or to bury a pipe in an area adjacent to a river, mountain, valley, or river to perform hydroelectric power generation. It is also possible to produce hydroelectric power in urban areas with high electricity demand.

For convenience of explanation, the drawings may be simplified or omitted, if necessary, to simplify the structure of the invention. Therefore, the respective constituent elements are not limited to the sizes and shapes shown in the drawings, and the size of each constituent element can be enlarged or miniaturized as necessary, and the design can be changed in various shapes as a matter of course . Further, it goes without saying that the present invention is not limited thereto, and various devices may be added, changed or omitted.

1 is a cross-sectional view of a hydroelectric power generating apparatus according to an embodiment of the present invention.

1, the hydroelectric power generating apparatus according to the present embodiment includes a channel portion 100 forming a channel 101 through which water flows, a shaft member 110 installed inside the channel portion, and a rotary member 120 And a connection part 200 provided on both sides of the conduit part 100.

The channel section 100 is formed in a cylindrical tubular shape and forms a channel 101 through which water flows. A flange 130 protruding outward is formed at both ends of the conduit part 100 and is configured to be connected to a connection part 200 to be described later through a flange 130.

The duct 100 may form a water supply pipe for supplying water to each facility from a water supply source or a drain pipe for transferring the sewage drained from each facility to a sewage treatment plant. In addition, it is possible to form an enlarged water flow pipe for hydropower generation using sea or river water in an area adjacent to the sea or a river. The channel portion may be embedded in the ground, or may be installed on the ground.

The diameter and length of the conduit section 100 can be variously determined in design, and when the existing water supply pipe or drain pipe is used, the diameter and length of the conduit pipe 100 can be configured to have a diameter and a length corresponding to the existing water supply pipe or drain pipe.

The shaft member 110 and the rotary member 120 are installed inside the conduit part 100 and generate electric energy by using the kinetic energy of the water current passing through the conduit part 100. 1, the shaft member 110 is fixedly installed in the conduit part 100, and the rotational member 120 moves the shaft member 110 by the kinetic energy of the water flow passing through the conduit part 100 And is rotatable about an axis.

The rotary member 120 includes a body portion 121 and a wing portion 122 installed along the outer side of the body portion 121.

The body portion 121 is formed of a cylindrical member that is elongated along the longitudinal direction of the rotary member 120. A hollow is formed in the body portion 121 to form a space for receiving the shaft member 110, Axis. At this time, at least one bearing 141 is formed between the inner surface of the body portion 121 of the rotary member 120 and the outer surface of the shaft member 110, thereby minimizing friction generated during rotation.

1, the wing portion 122 is configured to be wound in a spiral shape along the outer surface of the body portion 121. As shown in FIG. The wing portion 122 is arranged in a spiral shape having an inclination of 40 degrees or more with respect to the direction perpendicular to the longitudinal direction of the body portion 121. The wing portion 122 has a streamlined curved surface so as to obtain the maximum rotation Respectively.

The wing portion 122 protrudes outward from the body portion 121 and the end portion of the wing portion 122 may be configured to form a certain radius from the central axis of the body portion 121. [ At this time, the wing portion 122 is configured such that the length from the center (the center of the body portion) of the wing portion to the end portion is 0.75 times or more of the inner radius of the channel portion, so that the maximum rotational force can be ensured as the water flow advances And it is shown that the maximum rotational motion can be induced when the experimental result is 0.85 to 0.95 times. As described above, when the wing portion 122 is extended to the portion adjacent to the pipe radius, it is possible to perform the rotational motion even when the water flow passing through the pipe is small, and it is possible to prevent the foreign matter or the like from being precipitated in the pipe There is an advantage.

The shaft member 110 is disposed to penetrate the inside of the body 121 of the rotary member 120 and both ends of the shaft member 110 may be fixed to the support frame 210 of a connection portion to be described later. Accordingly, as the rotary member 120 rotates in the course of water flow, the rotary member 120 can rotate relative to the rotary member 120, and it is possible to produce electric energy using the relative rotary motion.

Fig. 2 is a cross-sectional view showing a cross section of the shaft member 110 and the rotating member 120 in Fig. As shown in FIG. 2 (a), the shaft member 110 is provided with a coil 111 wound on it, and the rotating member 120 may be provided with a permanent magnet 123. Therefore, when the rotating member 120 rotates, the permanent magnet 123 and the coil 111 wound on the coil 111 move relatively to change the magnetic field. As a result, a current flows on the coil 111 wound on the permanent magnet 123, have.

In the present embodiment, the coil is wound around the shaft member 110 and the permanent magnet 123 is provided on the rotating member 120. However, this is merely an example, and as another example, And the coil may be wound on the rotary member.

Specifically, as shown in FIG. 2A, the coil provided in the shaft member 110 may be wound along the outer side of the shaft member 110. Also, considering the water flow that may flow into the water flow during the water power generation, the coiled coil can be coated with the waterproof material 142.

The permanent magnet 123 provided on the rotary member 120 is disposed along the inner surface of the body portion 121 of the rotary member 120. In consideration of the water flowing into the hollow of the body portion 121, The exposed portion of the substrate 123 may be coated with a waterproof material 142.

However, as shown in FIG. 2B, the coil 111 is configured to be wound on the inner side of the shaft member 110 so as not to be exposed to the outside, The magnet 123 may be provided inside the body 121 of the rotary member so as not to be exposed to the outside. Or between the shaft member 110 or the support frame 210 and the shaft member 110 at both sides of the rotary member 120 so as to prevent flow of water into the hollow portion of the rotary member 120 in which the shaft member 110 is accommodated. It is also possible to form the space of the water-tight packing.

FIG. 3 is a front view showing the connecting portion in FIG. 1; FIG. As described above, the connecting portion 200 is configured to be coupled to both sides of the conduit portion 100. The connecting part 200 may be configured to have a shape corresponding to the both end flanges 130 of the conduit part 100 and to be coupled to the flange 130 of the conduit part 100. Inside the connection part 200, an opening corresponding to the channel of the channel part 100 is formed, and a space along which the water flow advances together with the channel of the channel part 100 can be formed.

At least one supporting frame 210 formed inside the opening 201 is formed in the conduit part 100. 3, the support frame 210 may include a coupling portion 211 to which the shaft member 110 is fixedly mounted, and a support portion 212 to support the coupling portion 211. As shown in FIG.

The coupling part 211 is formed of a hollow cylindrical member having a predetermined length in the longitudinal direction of the shaft member 110 and the end of the shaft member 110 may be inserted into and fixed to the coupling part 211. The support portion 212 is formed to extend from the inner wall surface of the opening 201 to the outer side of the coupling portion 211 to support the coupling portion 211.

At this time, the coupling portion 211 is configured to be electrically connected to the coil 111 of the shaft member 110 in a state where the end portion of the shaft member 110 is fixed, so that the electric energy generated from the coil 111 Can be delivered. The electric energy transmitted to the coupling part 211 is transmitted to the electric power transmission part 300 provided on the outside along the electric line formed on the coupling part 211 and the supporting part 212. Accordingly, the electric energy produced as the water flow proceeds can be supplied to the outside through the electric power transmission unit 300.

Although FIG. 3 shows a simple example of the connecting part according to the present embodiment, it is needless to say that the connecting part 200 can be formed in various forms other than the above-described structure. For example, the connection portion may be formed in a single block shape, and the upper structure and the lower structure may be formed in a detachable structure. In addition, in FIG. 3, one support frame is provided at one connection portion, and two shaft members provided at the respective channel portions disposed at both sides are fixed to one support frame. However, It is also possible to provide two support frames for fixing the shaft members of the conduit portion. It goes without saying that the shape of the fastening portion and the support portion can be variously modified in consideration of the shaft member and the water flow characteristics.

FIG. 4 is a front view showing a state in which a plurality of pipe portions are connected and installed according to the present embodiment, and FIG. 5 is a plan view showing another aspect in which a plurality of pipe portions are connected and installed according to the present embodiment.

4 and 5, both ends of the connection part 200 are respectively connected to the adjacent channel part 100, and the plurality of channel parts 100 are connected to each other through the connection part 200 . Accordingly, the plurality of conduit sections 100 and the plurality of connection sections 200 are alternately arranged, and electric energy can be produced using the kinetic energy of the flow path while forming the flow path of the water flow.

In this case, the connecting portion 200 may be formed as a straight block so as to form a flow path formed in a linear direction (see FIG. 4). In the case of forming a flow path to be bent, It is also possible to connect the respective channel portions with each other (see Fig. 5).

As described above, the flange 130 of the conduit part 100 and the connection part 200 are selectively removable by separate fastening members (not shown). Therefore, it is easy to manufacture and install, and it is possible to construct various types of pipelines according to the designed flow path. Further, when an abnormality occurs at a specific position, there is an advantage that the maintenance work can be performed or replaced easily by separating the pipeline and the connection portion at the corresponding position.

6 is a cross-sectional view of a hydroelectric power generating apparatus according to another embodiment of the present invention. As shown in FIG. 6, the hydroelectric power generation apparatus can be installed at a predetermined depth from the ground surface. The channel section 100 of the hydro-electric power generating apparatus may have a small-sized hollow 102 along the outer surface thereof. At this time, the size of the hollow 102 can be configured to have a diameter that is small enough to allow foreign matter such as soil to pass through and water to pass through. Therefore, the rainwater flowing through the ground surface or the groundwater existing in the ground can flow into the channel section 100 and be used for hydroelectric power generation. At this time, the plurality of hollows 102 may be formed only on the upper side of the channel section 100 to prevent the water flow passing through the inside of the channel from being leaked to the outside.

In this case, even in a region where the amount of the water flowing through the pipeline is small, the water existing in the basement flows into the pipeline, thereby contributing to the hydroelectric power generation. Further, even if there is no water in the pipeline, It is possible to carry out the hydroelectric power generation by using it.

Meanwhile, as shown in FIG. 6, the conduit part 100 according to the present embodiment may be provided with a conduit in a downward inclined shape with respect to a horizontal plane (plane having the same potential energy). In this case, the efficiency of hydroelectric power generation can be increased because water in the pipeline accelerates while moving downward. Furthermore, even if the water does not flow at all times, it is possible to produce electric energy by rotating the rotating member 120 inside the hydrostatic power generator while the water flowing from the outside flows in an inclined direction by the potential energy. Furthermore, it is also possible to provide the electric energy produced by the hydroelectric power generation device to external facilities or to sell electric energy.

In the above, the hydroelectric power generation apparatus capable of producing electric energy using the kinetic energy of the water current passing through the pipeline was described. The hydroelectric power generation apparatus may be constituted by a small scale device for application to a water supply and drainage facility of a small scale building or may be constituted by a large scale device for application to a large scale pipeline connecting main waterways.

Furthermore, it should be understood that the above-described embodiments may be modified and implemented in various ways in addition to those described above. Therefore, the scope of rights claimed in the present invention should not be limited to those described in the embodiments, but should be judged as to whether or not the features described in the claims are implemented.
