Description

An impeller canal power generation device

technical field

The invention belongs to the technical field of hydropower generation. Specifically relates to an impeller river canal power generation device. the

Background technique

At present, hydropower includes large-scale hydropower, medium-scale hydropower, and small-scale hydropower. Large-scale hydropower investment is huge and subject to geographical environment. Small and medium-sized hydropower also needs to build dams and stations on rivers of a certain scale. However, there are many mountains, rivers and streams in our country, but the geographical conditions do not meet the requirements for building small and medium-sized hydropower. These natural rivers have not been fully utilized. the

Utility model content

The utility model provides an impeller river canal power generation device that can be widely used in various large rivers and small rivers in view of the above shortcomings. the

The utility model is realized in the following way: an impeller river canal power generation device includes a frame, an impeller shaft, a bearing seat, an impeller blade, a driving sprocket, a driven sprocket, and a generator, and is characterized in that: the impeller shaft is installed on the On the frame, the bearing is fixed in the bearing seat, the impeller blade is fixed on the impeller shaft radially, and the drive sprocket is arranged at the shaft end of the impeller shaft, and the impeller blade, the drive sprocket and the impeller shaft rotate freely synchronously along the axis of the impeller shaft, and the generator Fixed on the frame, the generator shaft end is provided with a driven sprocket, and the driving sprocket and the driven sprocket are meshed through a chain. the

The device is installed on the canal. When the water flows, the impeller blades are driven to rotate around the impeller shaft. The driving sprocket and the impeller shaft rotate synchronously, and the driven sprocket is driven by the chain, so that the generator rotates to achieve the purpose of power generation. the

The device can be conveniently installed in various big rivers and small rivers or other places where water flows, and is not limited by the location of the ground, and can be popularized and applied in large quantities. At the same time, the length of the impeller shaft can be adjusted to adapt to rivers of different widths. The adjusting screw rod is installed on the frame of the device, and the purpose of lifting can be achieved by adjusting the screw rod. When there are floating objects in the river, the device can be raised to prevent the floating objects from clogging the impeller blades. the

In order to allow the device to work more efficiently, the impeller blades are set in a concave shape, and the concave surface of the impeller blades faces the upstream of the water flow. At the same time, in order to allow the device to work continuously, 3-9 impeller blades are provided. the

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the utility model is not limited to the following embodiments, and any changes or alternatives made on the principle of this embodiment all fall into the requirements of the utility model within the scope of protection. the

Referring to Figure 1 and Figure 2, the impeller shaft 8 is installed on the frame 1 through the bearing seat 4, the impeller blade 2 is fixed on the impeller shaft 8 in a radial shape, and the shaft end of the impeller shaft 8 is provided with a driving sprocket 3, the impeller blade 2, the driving chain The wheel 3 and the impeller shaft 8 freely rotate synchronously along the axis of the impeller shaft 8, the generator 6 is fixed on the frame 1, the shaft end of the generator 6 is provided with a driven sprocket 9, and the driving sprocket 3 and the driven sprocket 9 pass through the chain 5 meshes. The device is installed on the river canal. When the water flow drives the impeller blade 2 to rotate around the impeller shaft 8, the driving sprocket 3 and the impeller shaft 8 rotate synchronously, and the driven sprocket 9 is driven by the chain 5, so that the generator 6 rotates. In order to achieve the purpose of power generation. At the same time, the length of the impeller shaft 8 can be adjusted so as to adapt to rivers of different widths. The adjusting screw mandrel 7 is installed on the device frame 1, and the lifting purpose can be achieved by rotating the adjusting screw mandrel 7. When there are floating objects in the river, this device can be raised to prevent the floating objects from blocking the impeller blade 2. the

In order to make the device work more efficiently, the impeller blade 2 is configured to be concave, and the concave surface of the impeller blade 2 is directly facing the upstream of the water flow. Simultaneously, in order to allow the device to work continuously, the impeller blades 2 are provided with 3-9 blades. the
