Unless otherwise specified, in the following description, "plurality" means two or more.

Fig. 1 is a perspective view showing a first embodiment of a hydroelectric power generation device 10 in conjunction with the action shown in Fig. 2 . In this embodiment, the hydroelectric power generation equipment 10 includes: a set of fan blades 11, a transmission shaft 14, a set of universal joints 15, 17, a long rod 16, a short rod 161, a joint bearing 18, A gearbox 20 , a connector 21 and a generator 22 .

Wherein, each fan blade 11 has a joint portion 12 . According to the vortex direction, three blades 13 extend from the outer surface of the joint portion 12 . All the coupling parts 12 are sleeved on the transmission shaft 14, so that the group of fan blades 11 connected in series by the transmission shaft 14 can rotate in the same direction. A universal joint 15 connects the long rod 16 and the transmission shaft 14, and another universal joint 17 connects the long rod 16 and the short rod 161, so This group of universal joints 15, 17 is like a joint, and the transmission shaft 14, the long rod 16 and the short rod 161 are connected together. The gearbox 20 is also called a gear box. A shaft rod (see Fig. 4 , not labeled) respectively protrudes from both sides of the gear box. There is a ratio between the two shaft rods, which are used as input shafts and output shafts.

While the input shaft is connected to the stub 161 through the joint bearing 18 , the output shaft is joined to a shaft 23 of the generator 22 via the coupling 21 . The generator 22 is connected to at least one electrical line 24 .

When in use, the generator 22 and the universal joint 17 maintain a transverse connection, so the connector 21, the gearbox 20, the joint bearing 18 and the short rod 161 maintain a straight line. The long rod 16 is oblique, and forms an obtuse angle with the transmission shaft 14, so that the transmission shaft 14 is roughly parallel to the shaft 23 of the generator 22, and does not affect the group of fan blades 11 to drive the transmission shaft 14 to rotate in the same direction. In this way, the gearbox 20 receives the torque of the transmission shaft 14 through the long rod 16 and the short rod 161 , and can also change the torque or speed of the transmission shaft 14 . At the same time, the generator 22 converts the kinetic energy of the transmission shaft 14 into electrical energy, and outputs it to the outside through the wire 24 .

In this way, the group of blades 11 is used to float in a water well (not shown in the figure), without affecting the original irrigation and drainage function of the water well. Moreover, the group of blades 11 may generate relatively large torsion force, which increases the power generated by the generator 22 and can support public electricity consumption. Furthermore, the small hydroelectric power generation equipment 10 reduces investment costs, avoids damage to the environment, and has the advantages of power output.

In addition, a group of floating balls 27 is connected in series to the transmission shaft 14, and the transmission shaft 14 can rotate smoothly in the flowing liquid through the floating balls 27. In some embodiments, the hydroelectric device 10 retains at least one floating ball 27, which is also within the scope of the present invention.

Fig. 3 is also a perspective view, and cooperates with the action shown in Fig. 4 to show the structure of the second embodiment of the hydroelectric power generation equipment 10 of the present invention, which is roughly the same as the first embodiment structure, the difference lies in: firstly, the hydroelectric power generation equipment 10 has a main box 30, and the main box 30 protects the components from the generator 22 to the long pole 16, such as the connector 21, the gearbox 20, the joint bearing 18, the short Rod 161 and universal joint 17.

Secondly, the length of the pair of rails 32 is greater than the length of the main box 30, and the main box 30 is arranged at one end of the two rails 32 and is fixed.

Furthermore, a sub-box 31 is mounted on the other end of the pair of rails 32, capable of reciprocating relative to the main box 30, and the sub-box 31 is connected to the transmission shaft 14 through a universal joint 25 and a connecting rod 26. In other words, two ends of the transmission shaft 14 are respectively connected to the long rod 16 and the connecting rod 26 .

For example, the hydroelectric power plant 10 is moved to the vicinity of a ditch 40 , and the two rails 32 are fixed on the top surfaces 42 of the two walls 41 of the ditch 40 . By one of manual, electric and automatic methods, the auxiliary box 31 approaches the main box 30 along the length direction of the track 32, shortens the distance between the two, and supports the drive shaft 14 and the group of fan blades 11 with the long rod 16 and the connecting rod 26 Sink into the liquid surface 43 times.

According to the flow direction 44 indicated by the arrow in FIG. 4 , the liquid (usually flowing water) in the ditch 40 impinges on the blade 13 . Because the transmission shaft 14 is combined with the coupling portion 12 , the group of fan blades 11 drives the transmission shaft 14 to rotate in the same direction. The connecting rod 26 idles relative to the auxiliary case 31 and does not perform work. According to the preset value or the gear ratio, the gearbox 20 changes the torque of the transmission shaft 14 to drive the shaft 23 to act synchronously, so that the generator 22 generates electricity and outputs it to the outside through the wire 24 .

As shown in Figures 5 and 6, along the length direction of the track 32, the auxiliary box 31 is separated from the main box 30 by a distance between them. At this moment, the connecting rod 26 , the transmission shaft 14 and the long rod 16 are almost straightened, so that the set of fan blades 11 is suspended above the liquid surface 43 . Even if the liquid in the ditch 40 continues to flow in the flow direction 44 in FIG. 6 , the hydroelectric power generation device 10 will not generate electricity.

In this embodiment, in order for the reciprocating movement of the auxiliary box 31 to proceed smoothly, it is better that the main box 30 is usually provided with a long and narrow hole (not labeled) that allows the long rod 16 to swing.

Fig. 7 is a top view, showing the structure of the third embodiment of the hydroelectric power generation equipment 10 of the present invention, which is roughly the same as the structure of the first embodiment, the difference is: the generator 22 to the elements of the joint bearing 18 (such as the connector 21 and the joint bearing 18) The gearbox 20) is mounted on a swing arm 55.

Secondly, the swing arm 55 is pivotally connected to a foundation 53 , such as a protrusion 54 of the foundation 53 .

In use, the foundation 53 is fixed on a river beach 52, and the swing arm 55 swings toward a river 50, and through the support of the short rod 161 and the long rod 16, the transmission shaft 14 and the set of fan blades 11 sink into the river 50. According to the flow direction 51 in FIG. 7 , the set of fan blades 11 rotates together with the transmission shaft 14 , and the torque is transmitted to the generator 22 via the gearbox 20 to generate electricity.

Those skilled in the art can understand and make changes to the above-disclosed embodiments without departing from the broad concepts of the present disclosure. Therefore, this case is not limited to the specific embodiments disclosed in the specification, and all modifications made according to the spirit and technical scope of this case shall be covered and protected by the textual content defined in the scope of the patent application.
