The present invention relates to a generation system, and more particularly to a hydropower system generating power by flowing water.
With reference to
The flowing water diverted into the canal 72 from the flowing river 71 spins the water turbine 73 and drives a generator for generating electric power.
To improve power-generating efficiency, the water turbine 73 is placed in a segment of the canal 72 which is away from a headrace of the canal 72 with a large height difference. However, the conventional run-of-river hydropower system requires a canal 72 to be built alongside the flowing river 71. The construction is time-consuming and labor-intensive. Moreover, one canal 72 is only suitable for setting one water turbine 73, and power generation of the water turbine 73 is limited.
To overcome the shortcomings, the present invention tends to provide a hydropower system to mitigate or obviate the aforementioned problems.
The main objective of the invention is to provide a hydropower system which can generate power by flowing water flowing through an existing river directly. Thus, the construction of the hydropower system is easy and may reduce time and labor.
The hydropower system has a channel and at least one water turbine. The channel has two side walls, a flowing path, and at least one turbine recess. The at least one turbine recess is recessed in at least one of the side walls. Each turbine recess has a spinning space formed therein and an opening communicating with the flowing path. An amount of the at least one water turbine is equal to an amount of the at least one recess. Each water turbine is mounted in the spinning space of the corresponding turbine recess, and has a shaft, a blade wheel, and a generator. The shaft is vertically and axially rotatably mounted in the spinning space of the corresponding turbine recess. The blade wheel is mounted on and rotatable with the shaft, partially protrudes into the flowing path from the opening of the corresponding turbine recess, and has a base fixed on the shaft and multiple driving blades mounted around the base at equiangular intervals and extending radially. The generator is connected with the shaft.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The channel 10 is applied for flowing water F to flow through, and has two side walls 101, a flowing path 103, and at least one turbine recess 11. The two side walls 101 and the flowing path 103 may be formed from a flowing river directly. The at least one turbine recess 11 is recessed in at least one of the side walls 101 of the channel 10. The at least one turbine recess 11 may be multiple turbine recesses 11. The multiple turbine recesses 11 may be recessed in one of the side walls 101 and arranged along the side wall 101 at spaced intervals, or recessed in the two side walls 101 and each of the side walls 101 has at least one of the turbine recesses 11 formed therein. The turbine recesses 11 formed in the different side walls 101 may be arranged in opposite positions or in staggered positions. Each turbine recess 11 has a spinning space 111 and an opening communicating with the flowing path 103.
The amount of the at least one water turbine 200 is equal to the amount of the at least one turbine recess 11. Multiple said water turbines 200 are respectively mounted in the spinning spaces 111 of the multiple turbine recesses 11. Each water turbine 200 has a shaft 30, a blade wheel 20, and a generator 40. The shaft 30 is vertically and axially rotatably mounted in the spinning space 111 of the turbine recess 11. The blade wheel 20 is disposed under the flowing water F, is fixed on and rotatable with the shaft 30, partially protrudes into the flowing path 103 from the opening of the turbine recess 11, and has a base 21 and multiple driving blades 23. The base 21 is fixed on the shaft 30. The driving blades 23 are mounted around the base 21 at equiangular intervals and extend radially. The generator 40 is connected with the shaft 30. The blade wheel 20 will be propelled to rotate by the flowing water. F flowing through the flowing path 103, and the shaft 30 will be spinning with the blade wheel 20 to drive the generator 40 for generating electric power.
In the first embodiment of the water turbine 200, each driving blade 23 is a flat blade, and a portion of the driving blade 23 that is away from the base 21 protrudes into the flowing path 103 from the opening of the turbine recess 11.

With reference to
The water turbine 200B further has a guiding seat 50. The guiding seat 50 is a barrel, is mounted on the bottom of the shaft 30 in the turbine recess 11, and has an opening formed in the top thereof and a flowing hole 51 radially formed through the guiding seat 50. When the flowing water F drives the water turbines 200B to generate electric power, the water inside the turbine recesses 11 will be led into the guiding seats 50 and flow to the flowing path 103 via the flowing holes 51. The water inside the turbine recesses 11 will keep flowing to enhance the unimpeded rotation of the water turbines 200B and prevent the water from retaining in the turbine recesses 11.
With such arrangements, the water turbines 200, 200A, 200B can be propelled to generate power by flowing water F flowing through an existing river directly, and the multiple water turbines 200, 200A, 200B can be set alongside of the existing river to increase the power generation. The construction of the hydropower system in accordance, with the present invention is easy and may reduce time and labor.
