Description

Fence type power generating apparatus using flowing water}

The present invention relates to a power generating apparatus, and more particularly, to a power generating apparatus using aberrations rotated by running water so that it can be used for hydropower generation.

Conventional hydroelectric generation uses large mechanical dams to build large dams in order to achieve free fall, flow water into the water pipes using the free fall of the dam, and use the mechanical power generated when the flowing water impulses the aberration. On the other hand, hydrophobic power generation can be performed using the momentum of the flowing water even in places where the drop is not large.

Small hydroelectric power generation has the advantage of being able to supply energy in separated areas where facility cost is low and construction is not easy compared with hydroelectric power generation that requires large dams.

However, existing small hydro power generation is also generally carried out by stacking small beams for stable water supply, or constructing fixed facilities for installing water wheels. Therefore, it is difficult to rotate the aberration and generate power in such a fixed facility installation method in rivers, which have a small facility cost compared to power generation capacity and have a large flow rate according to the season, and therefore have a great change in depth, especially upstream or midstream. It is easy to fall.

In addition, when a small dam is built up, it often incurs maintenance costs to remove the sedimentary material from the dam, and may damage the environmental ecosystem. This can block the flow and cause nearby flooding.

The present invention is to solve such a conventional problem, the power using a flowable or variable type that can easily change the position or installation form to increase the efficiency and to reduce the management difficulties while using the flowing water locally. It is an object to provide a generator.

In addition, an object of the present invention is to provide a power generator using water flow that can simplify and lighten the aberration and the surrounding structure and improve the power generation efficiency to be suitable for operation in a movable or variable type.

Power generating device using the flowing water of the present invention for achieving the above object,

A plurality of unit aberrations having a case in which a through hole is formed in a longitudinal direction to form a flow path, a screw-shaped aberration installed in the through-hole, and a support shaft rotatably supporting the rotating shaft of the screw-shaped aberration, while being fixed to the case. Is arranged in a fence shape in the width direction of the unit aberration.

For this arrangement, a flow or rotatable link means is provided at the widthwise end of the unit aberration so that a plurality of unit aberrations can be coupled by this means.

In the present invention, at least a part of the case may be provided with a sealable empty space to float the case in water. At this time, the through hole should be made so that at least a part of the through-hole in contact with the water flowing through the screw wing in the normal state, the empty space is located in the upper portion of the case can be most of the state except the upper portion.

In the present invention, the case is preferably formed in such a way that the periphery of the inlet is widely extended so as to collect the running water at one end of the through hole, and the distance from the extended end to the support is smaller than the distance to the screw blades. It is desirable to be able to be stably supported.

In the present invention, the case can reach the bottom in a shallow river or the like, in this case, one end of the inlet side in the through hole is high, the outlet side is located so that the through hole is inclined, the water flowing around the inlet The periphery may form a slope that is lowered toward the front so that the entrance is well introduced. (The through-hole inlet can be formed higher than the longitudinal front and rear.)

In the present invention, the screw-type aberration may be arranged such that a plurality of screw blades are spaced apart from each other on the side of the rotation shaft to form a spiral. The connecting line connecting the screw blades can be rotated one or more times while drawing a spiral. In other words, the screw-type aberration can achieve a spiral aberration in which the wings overlap and turn when viewed from the front.

Case or screw, the support in the present invention may be made of a synthetic resin material, it may be formed by a synthetic resin molding.

According to the present invention, it is possible to easily change the location or installation form while using the flowing water locally, and it is easy to manage, and it is easy to install and use the optimum form at the optimum place at the appropriate time, thereby increasing the use efficiency.

In addition, the present invention can reduce the manufacturing and maintenance costs by simplifying and lightening the aberration and the surrounding structure to be suitable for operating in a movable or variable type.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a partial cross-sectional view showing the form seen from the side by cutting the case in the longitudinal direction in the unit aberration constituting an embodiment of the present invention.

The through hole 11 is formed in one direction in the case 10. When this direction is called longitudinal direction a, this invention apparatus is provided so that the longitudinal direction a of this unit aberration may correspond to the flow direction of flowing water. The end of the through hole 11 on the right side of the drawing becomes an inlet, and the flow of water flows in, and the running water is discharged to the end of the through hole on the left side.

The through-hole 11 is provided with a screw-shaped aberration 20 along the longitudinal direction. The skew-like aberration 20 largely consists of the rotating shaft 21 and the screw blades 23: fin. The blade-shaped portion of the rotary shaft 21 has an enlarged diameter compared to other portions to have a substantially cylindrical shape, and a screw blade 23 is formed on the side of the cylinder 25. In this embodiment, the screw-type aberration 20 is made by installing a screw blade on the side of the rotation shaft. Screw blades may be made of one, a plurality of screw blades 23 are spaced apart are arranged so that the connecting line connecting the wings to form a substantially spiral. In other words, the connecting line connecting the screw blades connected to the cylinder 25, which is the portion of the rotating shaft, the diameter of which extends, is drawn in a thread-like spiral. The spiral drawn on the side of the cylinder may have wings formed to rotate more than one round (four times in this embodiment). In other words, the screw-type aberration here can be said to be a spiral aberration in which the blades are pivoted overlapping in the longitudinal front (inlet side).

The screw-shaped aberration 20 is installed by rotatably fixing the rotation shaft 21 of the screw-shaped aberration 20 to the support 30 which is installed near the inlet portion of the through hole 11. The rotating shaft 21 passes through the longitudinal center of the screw-shaped aberration 20 in the longitudinal direction a. The screw-shaped aberration is formed in advance in the rotating shaft 21, the synthetic resin material is poured into the mold in a state in which the rotating shaft 21 is installed in the mold to form the screw blade 23 and the cylinder 25 to which the blade is attached. It can be manufactured by the insert injection method.

The support 30 is formed in a tricycle form so that three leg portions at the center thereof extend radially with respect to a plane perpendicular to the longitudinal direction of the case 10. The end of the leg is fixed in the through hole 11 of the case, and the leg portion is formed to have a thin thickness when viewed in a cross section cut in a plane perpendicular to the longitudinal direction so as not to disturb the flow of running water entering the inlet. The through-hole is formed in the center in the longitudinal direction to allow the rotation shaft 21 of the screw-shaped aberration 20 to pass. The rotary shaft 21 may be fixed with a pin or the like so as not to fall out of the support 30, and the contact surface between the rotary shaft 21 and the hole of the support 30 is treated with a sleeve or a separate bearing to facilitate rotation. Can be installed.

Although the position of the support 30 may be determined so that the rotating shaft 21 passes through the support 30 in the middle of the longitudinal direction of the winged portion, in this embodiment, the screw wing 23 of the screw-shaped aberration 20 is formed. Compared with the part, the support 30 is formed closer to the inlet side of the through hole 11. Therefore, the aberration can be maintained at the correct position due to the flow of running water, and the rotation of the aberration can be normally performed to properly maintain the rotational efficiency. In addition, if a gear or pulley or other mechanical element is installed at the front end (inlet end) of the rotating shaft 21 to pull out the aberration force to the outside, the support is advantageous for balancing the weight between these mechanical elements and the aberration. . However, when the support 30 is installed at the end of the rotating shaft 21 of the screw-type aberration (rear end when the flow of water is based), the screw-type aberration 20 may be bent by water pressure, in this case, the aberration It is preferable that the support 30 is not installed at the end of the rotation shaft because the rotation efficiency may be reduced.

On the other hand, the inlet portion of the through-hole 11 in the case 10 forms a diameter or wider toward the front (the direction in which water flows). Therefore, when water flows into the inlet, a larger amount of flowing water passing around the case may be introduced into the inlet, similar to the funnel, and the width of the through hole 11 passes through the through hole 11, which is the passage of the flowing water. This somewhat narrower effect can result in faster flow rates.

An empty space 13 (void) is formed in the case 10 at an upper portion of the through hole 11. This space 13 acts like a buoy so that the unit aberration 100 does not sink in the water but at least a portion floats on the surface of the water. The size and position of this space is combined with the unit aberration itself or these unit aberrations 100 in a state in which an element (not shown) for transmitting power to the inlet end of the rotation shaft 21 of the unit aberration 100 is coupled. It is determined in consideration of the weight, buoyancy and the like of the power generating device of the present invention. For example, running water should be introduced into the through hole 11 in the installed state, and the running water should be able to rotate at least a portion of the wing of the screw-type aberration 20 to rotate the screw-type aberration. Preferably, the amount of water passing through the through hole 11 is increased, and the position is such that the speed is high. In rivers, the velocity of runoff is greatest at the surface, so it is desirable that the hole pass surface water flowing through the surface rather than deep water.

Although not shown, at the inlet of the through hole, a filter net is installed at the entrance of the through hole to prevent the entry of suspended matter, garbage, etc., which are caught in the wing 23 of the screw-shaped aberration or the legs of the support 30 to prevent the operation of the aberration. Can be. The support may also act as a strainer by adjusting the number and shape of the legs and the location of the support.

FIG. 2 is a perspective view illustrating an embodiment of the present invention in which a plurality of unit aberrations having the same shape as that of FIG. 1 are arranged in a width direction.

In this embodiment, there is no separate element or configuration, such as a link structure, in which all of the cases forming unit aberration are integrally formed to couple the unit aberration in the width direction.

However, through-holes are not formed at the connection portion between the unit aberration and the unit aberration in the case, so that only the wall constituting the case exists. Therefore, by increasing the width of the connection portion and the material of the case itself constituting the connection portion with excellent elasticity and ductility material, the relative position can be elastically adjusted while the unit aberration is little by little depending on the flow.

3 and 4 are a plan view and a perspective view showing an embodiment of the present invention different from FIG.

In this embodiment, among the configuration of the unit aberration, the shape and configuration of the screw-type aberration or the support stand is similar to the previous embodiment. However, unlike the embodiment of FIG. 2, an empty space serving as a buoy in the case is not separately installed in the unit aberration portion.

However, even in such a configuration, the material of the screw-type aberration, the support, and the case forming the unit aberration is made of a material having a specific gravity lower than that of water, or by installing separate buoys or supports at both ends of the width direction (b direction in FIG. 1). It is also possible to keep the level of unit aberrations at a level suitable for generating power by screwing them by tying the buoys or supports with tensioned cables.

In addition, the front end of the connecting portion connecting the unit aberration and the unit aberration (part where it first collides with the running water) is streamlined like an airplane wing so that the device of the present invention does not fall into the water by the flowing force of the running water. It may be.

Such a device can be installed in such a manner that both ends of the entire widthwise direction are fixed to both sides of the river, one side of the river, or fixed to a fixture in the middle of the river.

5 to 8 are conceptual configuration diagrams showing the apparatus of the present invention installed in water such as a river while varying the level.

5 typically shows the apparatus 300 of the present invention installed in running water. When only one fixed side of the apparatus of the present invention is viewed, the lower side includes a fixing base 70 which is firmly fixed with a foundation concrete, a foundation bolt, etc. and which can be rotated in a horizontal plane, and the fixing table 70 rotates in a horizontal plane. One side of the horizontal support 75 is coupled. The other side of the horizontal support 75 is connected to the first link 80, one side of the connecting rod 90 is coupled to the first link (80). The other side of the connecting rod 90 is connected to the apparatus 300 of the present invention with the second link 85 interposed therebetween.

In this case, since the lower eye where the fixing table 70 is installed is higher than the surface of the flowing water, the connecting rod 90 has an inclination downward toward the apparatus 300 in which the unit aberrations are arranged in the width direction. Arrows here indicate the direction of flow.

Although not shown, the other side that is not coupled to the fixture 70 of the apparatus 300 may be coupled to the fixture of the opposite eye opposite to the lower eye where the fixture is installed, and the flow of water may be concentrated to the part where the device is installed in the entire stream. It can be installed to connect to an auxiliary fence that functions similar to a funnel. In addition, in the case where the ratio of the width to which the present invention device is installed in the total river width is small, the other side of the present invention is provided separately upstream of the bottom of the same bottom as the bottom where the fixing table 70 shown in FIG. 5 is installed. It can be fixed to the fixing device by using connecting rod or connecting cable.

Figure 6 shows that the surface of the flowing water is lowered so that the connecting rod makes a steeper downward slope toward the device of the present invention. If the surface of the flowing water is lowered in the state of FIG. 5, the device in the flowing water is also at a lower level. In addition, the connecting rod connecting the device 300 of the present invention and the horizontal support which is fixed at the level is coupled to both the first link and the second link, so that the inclination of the horizontal plane can be changed freely by the action of these links. have. As a result, when the surface of the flowing water is lowered, the level of the device is lowered, and the inclination of the connecting rod with the horizontal plane is more urgent. However, the apparatus of the present invention can maintain the power generation efficiency as in the case of FIG.

In Figure 7, the surface of the flowing water is increased, so that the connecting rod connecting the lower supporter or the horizontal support and the device is kept almost parallel to the horizontal plane. In Figure 8, the level of the flowing water is higher than the level at which the fixing unit is installed in the stream. It shows that the rod is inclined upward towards the device. Having such a connection structure, the invention device can change the level according to the flow of water level, so that even if the level of water flows within a short time, the power generator can continue to operate at an appropriate level without additional artificial adjustment. FIG. 8 may also represent a condition in which the device does not interfere with flow on the surface of the flowing water by raising the device artificially approaching another fixed end of the device of the present invention as shown, when the flowing water level rises in the short term. .

Fig. 9 shows a state in which the apparatus of the present invention, such as a flooding machine, is not properly operated, is rotated and attached to the lower side where the stator is installed, or lifted over the lower side. This will prevent the floats from colliding with the device and destroying the device or accumulating in the device and impeding the flow of running water.

On the other hand, the fixing of both ends as well as one end of the apparatus 300 of the present invention can be made detachable. In such a case, the fixing of both ends is dismantled at the position where it was originally installed but it is currently difficult to use, and the entire power generating device is transported by using water flow as it is, or it is loaded and transferred to the transport device in a disassembled state and then moved to another location. After all we can install detachably.

Although not shown, the unit aberration constituting the power generating apparatus of the present invention has a link means which is movable or rotatable at a widthwise end of the unit aberration when a plurality of unit aberrations are arranged in the width direction of the unit aberration so that the plurality of unit aberrations are provided. Can be combined by. For example, each node of the chain may have a form linked by a link pin. In this case, when a front is seen at the widthwise end of the unit aberration, a link hole into which the connecting pin can be inserted at the front left, rear end and the right middle part (length direction) is made, and the unit aberration is arranged in the width direction. Then, the link hole at the right middle part of the left unit aberration and the link holes at the left and right ends of the right unit aberration are aligned in the longitudinal direction, and the left and right unit aberrations are rotatable with each other by inserting the connecting pins in the link holes. Can be fixed

Fig. 10 is a perspective view showing a side aberration of the unit aberration 200 constituting another embodiment of the present invention.

The overall configuration has many parts similar to the unit aberration shown in FIG. There are some differences.

The through hole 41 is formed in the case 40 in the longitudinal direction. The end of the through-hole 41 on the right becomes an inlet, and the flow of water flows in, and the flow of water is discharged to the end of the through-hole 41 on the left. The inlet portion of the through hole 41 in the case 40 forms a diameter or width wider toward the front (the direction in which water flows).

Here, the empty space of the case 40 is located below the through hole 41 through which the flowing water passes. Here too, the volume of the empty space can be determined so that the Higgs-type power generator of the present invention does not sink in water but partially floats and the flowing water is sufficiently introduced into the through hole to efficiently rotate the screw-type aberration 50. However, when the amount of running water is not sufficient and the depth of the water is not secured, the lower part of the unit case 40 is installed to reach the bottom, such as the bottom of the river. The shape of the case 40 is such that the inlet end is high in the through hole 41 and the outlet end is low when the case reaches the bottom so that the through hole is inclined downward in the longitudinal direction.

In addition, the inlet end portion has a shape in which the periphery extends widely toward the front, while the lower portion 45 is inclined forwardly to form a water overflow with respect to the flowing water.

Therefore, in the unit aberration 200 of this embodiment, the flowing water approaching the inlet of the through hole 41 is inclined in front of the inlet by the speed even if the level is higher than the inlet of the through hole 41. Ride up and flow along the lower portion 45 forming the water overflows the inlet. In addition, the inlet flows along the through-hole 41 by the rear inclined from the inlet and rotates the rotary shaft 51 while impinging the blade 53 of the screw-shaped aberration 50 installed in the through-hole 41. .

The configuration of the screw-shaped aberration 50 and the support 60 supporting the same is the same as the screw-shaped aberration and the support forming the unit aberration of FIG. 1, but the through hole 41 is inclined so that the rotation axis of the screw-shaped aberration 50 51 is also inclined, and the front end (through hole inlet side end portion) faces forward upward in the longitudinal direction.

Since the end position of the rotary shaft 51 is located outside the surface of the flowing water, it is advantageous to install a mechanical element or an electrical device at the end of the rotary shaft 51 as compared with the unit aberration of FIG.

Although not shown here, the inlet of the through-hole 41 prevents entry of suspended matter, garbage, etc., which hinders the operation of the aberration by being caught in the blade 53 of the screw-shaped aberration or the support 60 leg when introduced into the through-hole. A strainer can be installed further.

11 and 12 are perspective and plan views showing an embodiment of a power generator in which a plurality of unit aberrations of FIG. 10 are arranged in the width direction.

In the connecting part between the unit aberrations, a ridge or floor is formed at the periphery of the through-hole inlet of the case, and a valley is formed between the lower part of the through-hole inlet and flows to the inlet of the through-hole as much as the runoff approaches the inlet. Is focused to pass through.

According to the apparatus of the present invention, the unit aberration in the entire power generating device is segmented (when connected by a link) at the current installation position, or the connecting portion is elastic, so that the proper level can be maintained by flowing water. Will be maintained. Therefore, the maximum flow of water flows into the through-hole efficiently, and it is possible to escape while turning the screw-type aberration.

In addition, since most cases, supports, and screw-shaped aberrations that form unit aberrations can be easily formed through molding using a material such as synthetic resin, manufacturing and installation costs can be reduced, and the installation location, the form of installation, and the entire device can be reduced. It is possible or easy to flexibly adjust the number of unit aberrations to be achieved depending on the surrounding conditions.

On the other hand, there may be a variety of ways to draw the power available from the end of the rotary shaft of the screw-type aberration to the outside. For example, a method of drawing the end of the rotating shaft with a small generator fixed through the whole device and drawing it out as a lead wire or storing it in a battery may be considered as a kind of power generating device.

Alternatively, the gear may be installed at the end of the rotation shaft, and the rotational force of all the rotation shafts may be gradually transmitted to one end in the width direction of the apparatus by connecting the gears and the gear box at the ends of the rotation shafts of adjacent unit aberrations. (For example, a bevel gear or the like may be used in a portion where the rotating shaft of the unit aberration and the common shaft which receives and transfers the power of the rotating shaft are orthogonal to each other.)

In a similar way, instead of installing gears at the ends of the rotating shaft and using gearboxes between adjacent rotating shafts, the rotational forces of all the rotating shafts can be exerted through the chain of chains or chains (elements with teeth on the belt to mesh with the pinion gears). It can be used as mechanical power by gathering in two or distributed directions. Of course, gears and chains can be replaced by conventional dedicated means such as pulleys and belts, but it is necessary to take into account the lossless transmission of torque.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical spirit of the present invention, and such modifications and modifications belong to the appended claims. .
