Description

Simple hydroelectric power plant

technical field

The utility model relates to a mechanical device installed on rivers and canals to generate electricity by running water, in particular to a simple hydroelectric power generation device.

Background technique

my country is a big country rich in water resources. Various reservoirs are often seen on the vast rivers. The lower part of the dam of the reservoir is generally equipped with a hydroelectric generator set. Using the water level difference in the reservoir, the water flow hits the water turbine at a high speed, and the water turbine rotates at a high speed. That is to say, it can generate a steady stream of electric current and send it to thousands of households. However, the construction cost of the existing hydropower stations is very high, the technology is complex, and they are often built on rivers with a large water drop, which makes it impossible for the vast remote areas of our country to use local hydropower resources for hydropower generation, which seriously restricts the development of the local economy. develop.

Utility model content

The purpose of this utility model is to provide a simple hydroelectric power generation device, not only simple in structure, less investment, low production cost, but also small in size, light in weight, easy to manufacture, easy to install and use, and easy to be accepted by ordinary consumers. Installed on rivers and channels for hydropower generation, it is conducive to promoting economic development in remote areas.

The purpose of this utility model is achieved in this way: a simple hydroelectric power generation device, including a frame and a generator installed on the frame, a gear speed increaser is also installed on the frame, and the power output shaft of the gear speed increaser Connected with the rotating shaft of the generator, support arms are vertically and evenly distributed on the power input shaft of the gear speed increaser, and blades are respectively installed on the free ends of each support arm.

When the utility model is in use, it is installed on a river or a channel, and the blade installed on the support arm is extended into the water. Under the promotion of the water flow, the blade drives the power input shaft of the gear speed increaser through the support arm to rotate, and the gear The speed increaser drives the generator shaft to rotate at a high speed through its power output shaft to generate electricity. The utility model is not only simple in structure, low in investment, low in production cost, but also small in size, light in weight, easy to manufacture, easy to install and use, and easy to be accepted by ordinary consumers. It is conducive to promoting the economic development of remote areas.

Detailed ways

A simple hydroelectric power generation device, as shown in Figure 1, includes a frame 1 and a generator 5 installed on the frame 1, a gear speed increaser 4 is also installed on the frame 1, and the power of the gear speed increaser 4 The output shaft is connected with the rotating shaft of the generator 5, the power input shaft 2 of the gear speed increaser 4 is vertically and evenly distributed with support arms, and blades 3 are respectively installed on the free ends of each support arm. The number of support arms is 2-10, which is beneficial to increase the rotating speed of the power input shaft 2 . As shown in Figures 1 and 2, the blade 3 is a dustpan-shaped blade with an inner concave water surface, and its open end is connected to the support arm, and the water surface of the blade 3 faces the flow direction of the water flow. The dustpan-shaped blade can bear the thrust of the water flow as much as possible, which is beneficial to increase the rotating speed of the blade 3 . As shown in Figure 1, for a channel with a small cross-sectional area, the frame 1 can adopt a gate-shaped structure, and the frame 1 is installed across the channel, and the blades 3 are extended into the water in the channel. You can generate electricity. As shown in Figure 3, for wider rivers, the power input shaft 2 of the gear speed increaser 4 should be made longer, so that the end with the blades 3 can be extended to the middle of the river as much as possible, thereby effectively utilizing the water flow Thrust, improve the rotating speed of blade 3, improve power generation efficiency. The utility model support arm and blade 3 all adopt light material (as carbon fiber, aluminum alloy etc.) to make, so that reduce the bending deformation phenomenon of the power input shaft 2 of gear speed increaser 4.
