Description

The present disclosure relates to a hydroelectric power generation device having an adjustment mechanism having both tension adjustment and position adjustment in the direction parallel to the axis.

As an example of a conventional hydraulic power generator, an impeller shaft installed between an inner cylinder and an outer cylinder, which is rotated by a water flow, a first sprocket directly connected to the impeller shaft, and a generator installed outside the flow path. Axial water flow consisting of a transmission connected to a generator, a second sprocket directly connected to the transmission, and a transmission member such as a chain or belt connecting the first sprocket and the second sprocket. There is a vehicle-type power generator (see, for example, Patent Document 1).

In such a conventional hydroelectric power generation device, the power of the impeller axle rotated by the water flow is transmitted from the first sprocket to the second sprocket via the transmission member, and after being changed by the transmission, it is transmitted to the generator. It has a structure to be used.

The transmission member for transmitting power from the first sprocket to the second sprocket usually needs to generate proper tension. In the conventional hydroelectric power generation device according to Patent Document 1, the tension is adjusted by changing the height position by moving the second sprocket in a circular motion around the rotation axis of the transmission.

Japanese Unexamined Patent Publication No. 2002-242811

However, the prior art has the following problems.
The conventional hydroelectric power generation device according to Patent Document 1 has an adjustment structure only for the tension of the transmission member, and there is no position adjustment in the direction parallel to the axis. However, it is also important for the transmission member to adjust in the direction parallel to the axis.

If the position in the parallel direction of the axis shifts, the transmission member tilts. For this reason, in the case of a friction conduction type belt, power loss due to slippage, life reduction due to local wear, abnormal noise, vibration, and the like occur. Further, in the case of a toothed belt or a metal chain, power loss due to tooth skipping, life reduction due to local wear, abnormal noise, vibration and the like occur.

Regarding the position in the axis parallel direction, it is possible to suppress the inclination to a certain level or less in advance depending on the accuracy of the device parts. However, the required angle accuracy may be 0.1 degrees or less in some cases.

Therefore, considering the variation of parts from the first sprocket to the second sprocket, there is a concern that the required tilt angle is not satisfied. Further, even if the required tilt angle is satisfied, high-precision parts, assembly, etc. are required, and there is a concern that these costs will increase.

Further, in the conventional hydroelectric power generation device according to Patent Document 1, a tension adjusting device having a shaft different from that of the water wheel shaft and the generator / transmission shaft is used for adjusting the transmission member. Therefore, parts such as a shaft and a bearing for forming this shaft structure and a complicated transmission member such as a gear for transmitting power from the tension adjusting shaft to the transmission are required. As a result, the assembly man-hours are required, and there is a concern that the parts cost and the assembly cost will increase.

The present disclosure has been made to solve such a problem, and an object of the present invention is to obtain a hydroelectric power generation device having an adjustment mechanism having both tension adjustment and position adjustment in the axis parallel direction.

The hydraulic power generation device according to the present disclosure includes a first rotating body provided at one end of the rotating shaft of the water turbine, a second rotating body provided on the rotating shaft of the speed increaser directly connected to the generator, and the first. It is a hydraulic power generation device equipped with a transmission member for transmitting power from the rotating body of the above to the second rotating body, and has a first adjusting mechanism for adjusting the position of the rotating shaft of the speed increaser in a direction parallel to the axis and an increasing speed. Further provided with an adjustment mechanism having a second adjustment mechanism for adjusting the position in the vertical direction of the axis corresponding to the distance from the rotation axis of the water wheel with respect to the rotation axis of the machine, the first adjustment mechanism performs the rotation angle motion by a linear distance. The mechanism that converts the rotation angle motion into a linear distance motion enables the position adjustment in the axis parallel direction, and the second adjustment mechanism enables the position adjustment in the axis parallel direction by the mechanism that converts the rotation angle motion into a linear distance motion . The adjustment mechanism is a flat plate A as a base, a flat plate B that moves on the flat plate A in an axially parallel direction, a flat plate C fixed to the flat plate B, and a flat plate D and a flat plate E fixed to the flat plate A. The first rotation-linear motion conversion component that is communicated with the flat plate D and the flat plate E and enables the flat plate B to be moved in the axial parallel direction by rotation to adjust the position in the axial parallel direction, and the end of the position adjustment in the axial parallel direction. Later, a fixing member for fixing the flat plate B to the flat plate A is provided, and the second adjusting mechanism is made to pass through the flat plate F that moves in the vertical direction of the axis and the flat plate F, and moves the flat plate F in the vertical direction of the axis by rotation. Between the second rotation-linear motion conversion component that enables position adjustment in the vertical axis direction by adjusting the distance to the flat plate B, and between the flat plate B and the flat plate F after the position adjustment in the vertical direction of the axis is completed. A plurality of spacers are arranged in the flat plate F, and the flat plate F and the spacer are passed through each other to provide a fixing member for fixing the flat plate F to the flat plate B. After completing the position adjustment of the flat plate B in the direction, the flat plate B can be fixed to the flat plate A, and the flat plate F is moved in the vertical direction of the axis by the second adjustment mechanism to adjust the distance from the flat plate B. After completing the position adjustment in the vertical direction, the flat plate F can be fixed to the flat plate B, and the position adjustment and fixing in the axis parallel direction with respect to the flat plate F and the position adjustment and fixing in the vertical direction with respect to the flat plate F are possible.

Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings, and the same or corresponding members and parts will be described with reference to the same reference numerals in the drawings.

Embodiment 1.
FIG. 1 is a perspective view of the hydroelectric power generation device 1 according to the first embodiment of the present disclosure. Of the hydroelectric power generation device 1 according to the first embodiment, the water turbine main body 2 has a wing portion 3 that rotates by the pressure of a water flow, a disk portion 4 that holds the wing portion 3, a water turbine rotation shaft 5, and a frame 6 that holds them. , And a first rotating body 7 directly connected to one end of the water turbine rotating shaft 5.

On the other hand, the power generation device 8 is composed of a generator 9, a speed increaser 10 directly connected to the generator 9, and a second rotating body 12 directly connected to the speed increaser rotating shaft 11. The power generation device 8 is attached to an adjustment mechanism 13 described later.

Next, the power generation system will be described. When the wing portion 3 receives pressure from the water flow, the water turbine rotating shaft 5 of the water turbine body 2 and the first rotating body 7 directly connected to the water turbine rotating shaft 5 rotate. The power generated by this rotation is transmitted to the second rotating body 12 by the transmission member 14. The transmitted power is accelerated by the speed increaser 10 directly connected to the second rotating body 12 and transmitted to the generator 9, so that power generation is performed.

The transmission member 14 needs to be in close contact with the first rotating body 7 and the second rotating body 12 in order to transmit power. Therefore, the transmission member 14 is composed of a deformable member such as a belt or a metal chain.

When the transmission member 14 is a belt, the first rotating body 7 and the second rotating body 12 are composed of pulleys. When the transmission member 14 is a metal chain, the first rotating body 7 and the second rotating body 12 are composed of gears such as sprockets. For the belt and pulley, a friction conduction type, a toothed type, or the like can be selected.

FIG. 2 is a schematic view of the first rotating body 7, the second rotating body 12, and the transmission member 14 according to the first embodiment of the present disclosure. Since the transmission member 14 needs to transmit appropriate power, it is necessary to generate an appropriate tension and suppress the inclination in the axial direction.

In order to generate an appropriate tension, it is necessary to set the vertical distance ΔH between the axis of the first rotating body 7 and the axis of the second rotating body 12 to be an appropriate distance. Further, in order to suppress the inclination in the axial direction, it is required to keep the distance difference ΔL in the parallel direction between the axis of the first rotating body 7 and the axis of the second rotating body 12 within an allowable value.

FIG. 3 is a perspective view of the power generation device 8 according to the first embodiment of the present disclosure. Further, FIG. 4 is a perspective view of the perspective view of FIG. 3 in the first embodiment of the present disclosure as viewed from the rear side. The power generation device 8 is attached to the adjusting mechanism 13 as shown in FIGS. 3 and 4.

Among the adjusting mechanisms 13, the first adjusting mechanism for adjusting the positions of the first rotating body 7 and the second rotating body 12 in the axial parallel direction includes flat plates 15 to 19 and screws 21 to 23. It is composed of. The flat plate 15 is a flat plate as a base. The flat plate 16 is a flat plate that moves on the flat plate 15 in the direction parallel to the axis. The flat plate 17 is a flat plate fixed to the flat plate 16. The flat plate 18 and the flat plate 19 are flat plates fixed to the flat plate 15.

The screw 21 and the screw 22 are first rotation-linear motion conversion components that are communicated with the flat plate 18 and the flat plate 19 and move the flat plate 16 in the direction parallel to the axis by rotation. Further, the screw 23 is a fixing member for fixing the flat plate 16 to the flat plate 15 after the position adjustment in the axis parallel direction is completed. Here, the axis parallel direction is a direction parallel to the speed increaser rotating shaft 11, and is a direction in which ΔL can be adjusted in FIG. 2 to enable position adjustment.

Further, among the adjusting mechanisms 13, the second adjusting mechanism for adjusting the tension of the transmission member 14 includes a flat plate 24, a screw 27, a plurality of spacers 28, a screw 29, a guide plate 20, and a pin 26. There is. The flat plate 24 is a member that can move in the direction perpendicular to the axis for adjusting the tension of the transmission member 14. The screw 27 is a second rotation-linear motion conversion component that is passed through the flat plate 24 and moves the flat plate 24 in the direction perpendicular to the axis that adjusts the tension of the transmission member 14 by rotation. Here, the axis vertical direction is a direction corresponding to the distance of the speed increaser rotating shaft 11 from the water turbine rotating shaft 5, and is a direction in which ΔH is adjusted in FIG. 2 to enable position adjustment.

The plurality of spacers 28 are arranged between the flat plate 16 and the flat plate 24, and serve to maintain the adjusted tension. The screw 29 serves as a fixing member for fixing the flat plate 24 to the flat plate 16 by passing the flat plate 24 and the spacer 28 through each other.

The guide plate 20 serves to regulate the movement of the flat plate 16 other than the direction parallel to the axis. Further, the pin 26 is communicated with the hole 25 provided in the flat plate 24, and serves to regulate the movement of the flat plate 24 in a direction other than the axial vertical direction for adjusting the tension of the transmission member 14.

Next, the first adjusting mechanism for adjusting the positions of the first rotating body 7 and the second rotating body 12 in the axial parallel direction, and the axis vertical between the first rotating body 7 and the second rotating body 12. A method of assembling the adjusting mechanism 13 including the second adjusting mechanism for adjusting the tension of the transmission member 14 by adjusting the position in the direction will be described.

First, the flat plate 18 and the flat plate 19 are fixed to the flat plate 15, and the flat plate 15 is fixed to the frame 6. On the other hand, the flat plate 17 is fixed to the flat plate 16, the pin 26 is inserted into the flat plate 16, and the flat plate 24 on which the power generation device 8 is mounted is aligned on the flat plate 16 so that the pin 26 can be inserted into the hole 25. To be installed in.

Next, the flat plate 16 is arranged on the flat plate 15, the guide plate 20 is fixed to the flat plate 15, and the screws 21, the screws 22, and the screws 27 are attached. Finally, the transmission member 14 is locked to the first rotating body 7 and the second rotating body 12. The assembly method described here is an example, and there is no problem even if the assembly method or the order is changed.

Next, the adjustment method of the adjustment mechanism 13 will be described. First, a mechanism for adjusting the positions of the first rotating body 7 and the second rotating body 12 in the axial parallel direction will be described with reference to FIG. FIG. 5 is a schematic diagram for explaining the position adjustment in the axis parallel direction in the first embodiment of the present disclosure.

When the screw 21 is rotated to the right, the end portion 31 of the screw 21 pushes the flat plate 16 in the direction of the arrow indicated as the direction 1, that is, in the direction approaching the center in the width direction of the water turbine. As a result, the flat plate 16 moves in the direction of the arrow in the direction 1.

On the other hand, when the screw 22 is rotated to the right, the end portion 32 of the screw 22 pushes the flat plate 16 in the direction of the arrow indicated as the direction 2, that is, in the direction away from the center in the width direction of the water turbine. As a result, the flat plate 16 moves in the direction of the arrow in the direction 2. Direction 1 and direction 2 correspond to the direction parallel to the axis.

By such adjustment, the screw 21 and the screw 22 are appropriately adjusted so that the inclination of the transmission member 14 (that is, the value corresponding to ΔL shown in FIG. 2) is equal to or less than a predetermined value, and after the adjustment is completed, the screw is screwed. The flat plate 16 is fixed to the flat plate 15 at 23.

The insertion hole 33 of the screw 23 in the flat plate 16 is an elongated hole. Therefore, even after the flat plate B16 is moved in the direction parallel to the axis by adjustment, the structure is such that the fastening using the screw 23 is possible.

In order to smoothly move the flat plate 16, the contact surfaces of the flat plate 15, the flat plate 16, the flat plate 17, and the guide plate 20, the male screw portion of the screw 21 and the screw 22, and the female screw portion of the flat plate 18 and the flat plate 19 , The end 31 of the screw 21 and the end 32 of the screw 22 may be treated with a lubricant or the like.

Next, a mechanism for adjusting the tension of the transmission member 14 will be described with reference to FIG. FIG. 6 is a schematic diagram for explaining the tension adjustment of the transmission member 14 in the first embodiment of the present disclosure.

As the screw 27 is rotated to the right, the end portion 34 of the screw 27 comes into contact with the flat plate 16. Even after the contact, by further rotating the screw 27 to the right, the flat plate 24 moves in the direction of the arrow indicated as the direction 3, that is, the direction in which the tension of the transmission member 14 is increased.

On the other hand, when the screw 27 is rotated to the left from this state, the flat plate 24 moves in the direction of the arrow indicated as the direction 4, that is, in the direction in which the tension of the transmission member 14 is reduced. Direction 3 and direction 4 correspond to the direction perpendicular to the axis.

By such adjustment, the screw 27 is appropriately adjusted so that the tension of the transmission member 14 becomes an appropriate value (that is, ΔH shown in FIG. 2 becomes an appropriate value). Further, in order to maintain the tension of the transmission member 14, a spacer 28 is arranged between the flat plate 16 and the flat plate 24 and fixed with screws 29.

As the spacer 28, there is no problem even if different types of spacers are prepared and used in combination with an ultra-thin shim or the like as needed. Further, in order to smoothly move the flat plate 24, a lubricant is applied to the contact surface between the flat plate 24 and the pin 26, the male screw portion of the screw 27, the female screw portion of the flat plate 24, and the end portion 34 of the screw 27. May be applied.

In the structure of FIGS. 1 to 6 as described above, in addition to the tension adjustment of the transmission member 14 which is normally performed, the adjustment in the axial parallel direction is also possible. Therefore, in addition to optimizing the tension of the transmission member 14, the inclination in the axial direction can be easily adjusted within the allowable value.

Therefore, when a friction conduction type belt is used, it is possible to suppress power loss due to slippage, shorten the life due to local wear, and suppress abnormal noise, vibration, and the like. Further, when a toothed belt or a metal chain is used, power loss is eliminated by eliminating tooth skipping, and it is possible to suppress life reduction, abnormal noise, vibration and the like due to local wear.

Further, the adjusting mechanism 13 according to the first embodiment is provided as an integrated device that can adjust both the axial parallel direction and the tension directly under the power generation device 8. The adjusting mechanism 13 is mainly composed of parts having a generally simple shape such as a flat plate, a screw, a pin, and a spacer, and the structure is also simplified. Therefore, it is possible to reduce the parts cost and the assembly man-hours as compared with the configuration with complicated shaped parts.

Further, the movement of the flat plate 16 and the flat plate 24 for adjusting the axis parallel direction and adjusting the tension is performed by converting the rotation angle motion of the screw 21, the screw 22, and the screw 27 into a linear distance motion. Therefore, the linear movement distance can be reduced to a few millimeters by the nominal screw, the selection of the pitch, and the adjustment of the rotation angle.

Therefore, it is possible to make adjustments by minute movement of the flat plate, and it is possible to approach the adjustments with extremely desired accuracy. From this, even when the inclination of the belt increases or the tension decreases due to a change with time, it is possible to prolong the time until the allowable value is exceeded. As a result, the time until maintenance can be extended, which leads to a longer life and a reduction in maintenance man-hours.
