Description

River hydroelectric power generation system

The invention provides a power generation system, especially a river hydroelectric power generation system applied to rivers.

Large-scale power plants can output sufficient power, but once there is an accident in power distribution, voltage rise and fall, etc., the power supply will have to be suspended. Decentralized generation and small power plants are therefore another option for today's electricity supply.

In the known small-scale hydroelectric power generation technology, a parallel waterway is dug along the stream or river, and then turbine blades are arranged in the waterway to generate electricity by hydropower.

The creator believes that the small-scale hydroelectric power generation system of the known technology must dig waterways, which is difficult to popularize and install. Therefore, the creator has exhausted his mind and researched carefully, and then developed a river hydroelectric power generation system in order to achieve a wide application and convenience. Purpose of installation.

The invention provides a river hydroelectric power generation system, which is applied to a river with a high channel and a low channel, and there is a height difference between the low channel and the high channel. The river water wheel power generation system includes a water gate and a water wheel. The water gate includes a gate body. The door body is arranged on the low water channel to block the water flow of the low water channel, and the bottom of the door body has a channel for water to flow through. The water wheel is pivotally connected to the door body and is located downstream of the low channel compared with the door body. The water wheel is used to be driven to rotate by the water flowing through the channel, thereby generating mechanical energy for conversion into electrical energy.

In one embodiment, the gate body of the water gate has an accommodating portion for accommodating the water wheel.

In one embodiment, the body of the water gate has a top. The top is used to supply water to overflow and flow out during the flood season of the river.

In one embodiment, the river hydroelectric power generation system may further include a generator. The generator is arranged on the bank and connected to the water wheel by transmission, so as to receive the mechanical energy generated by the water wheel and convert the mechanical energy into electric power.

In one embodiment, the water wheel includes a water wheel shaft and a plurality of blades attached to the water wheel shaft.

In one embodiment, the waterwheel axis corresponds to the width of the lower channel.

In one embodiment, the diameter of the water wheel shaft is related to the average water depth and the average water flow of the low channel.

In one embodiment, the blades include a plurality of first blades and a plurality of second blades, and in a transverse direction of the water wheel shaft, the first blades are juxtaposed with the second blades, and in a circumferential direction of the water wheel shaft , the first blades and the second blades are arranged alternately.

Therefore, the river hydroelectric power generation system created in the present invention can be installed in rivers with height differences through simple installation without the need to dig additional water channels, thus having the advantage of being widely applicable.

In order to fully understand the purpose, characteristics and effects of this creation, I will give a detailed description of this creation through the following specific embodiments and the accompanying drawings. The description is as follows: Please refer to Figures 1 to 4. As shown in Figures 1 and 2, the invention provides a river hydroelectric power generation system 100, which is applied to a river R with a high channel H and a low channel L, and there is a gap between the low channel L and the high channel H A height difference S. The river water turbine power generation system 100 includes a water gate 101 and a water wheel 102 . The water gate 101 includes a gate body 103 . The door body 103 is disposed on the low water channel L to block the water flow of the low water channel L, and the bottom of the door body 103 has a channel FL for water to flow through. The water wheel 102 is pivotally connected to the door body 103 and is located downstream of the low channel L compared to the door body 103 . The water wheel 102 is used to be driven to rotate by the water flowing through the flow channel FL, so as to generate mechanical energy for converting into electrical energy.

As mentioned above, the river hydroelectric power generation system 100 of the present invention can be installed on a river R having a height difference S through simple installation without additional excavation of water channels, thus having the advantage of being widely applicable.
