Description

Micro hydropower unit

This creation is related to a kind of micro hydropower generating device, especially a micro hydropower generating device that can be installed between rivers and channels, using rivers and natural water streams for power generation.

According to the development of electric power, the development of the national industrial and commercial economy is a concrete manifestation of national strength. Therefore, countries around the world are not committed to power development, and can meet the needs of domestic electricity use. At present, the more widely used power generation methods are nothing more than nuclear power generation, thermal power generation, solar power generation, wind power generation, and hydropower generation. However, these power generation methods have their own advantages and disadvantages.

It is noted that nuclear power generation, which is the main source of electricity, has the advantages of lower power generation costs and can effectively reduce pollution and greenhouse gas emissions. However, the safety of nuclear energy and radiation pollution have been deeply questioned, leading to the anti-nuclear sounds; especially after the accident at the Fukushima nuclear power plant in Japan in March 2011, the dispute over the existence and disposal of nuclear power plants became more serious.

Thermal power generation (including: coal, oil and natural gas), another major source of electricity, is safer. However, it will emit excessive carbon dioxide and waste gas, causing air pollution and global warming, which will seriously damage the ecological environment.

In contrast, green energy, such as solar power, wind power, and hydropower, which are regulated and standby power, has become a trend of future energy development because of its advantages of safety, pollution-free, and renewable.

After investigation, hydropower mainly uses the water level drop in gravity The kinetic energy is formed to impact the turbine and rotate it to convert the kinetic energy into mechanical energy, which is then driven by the turbine to generate electricity. Although this type of power generation is more powerful than large-scale hydropower plants, relatively large-scale hydropower plants are built. Not only the infrastructure and the investment of the units are huge, but they are also bound to cause damage to the surrounding environment, ecology and land. It is in line with the local public opinion of the construction site, and the difficulty is quite high.

In view of this, the creators of this case can use the natural geographical advantages of China's rivers and channels to generate electricity for the purpose of regulating, standby power or power in neighboring areas to effectively utilize natural water resources.

Therefore, this creation is to provide a kind of water that can be installed between rivers and channels, using water flowing through rivers and channels to drive turbines, and after driving and accelerating, driving generators to generate electricity, which can increase power generation. Efficacy to meet the trend of green energy and environmental protection micro-hydropower devices.

The creation system comprises: a door frame, a water turbine, a transmission rod, a transmission and a generator. The span between the two sides of the portal frame depends on the width of the selected river and the channel, and A bearing seat is respectively arranged at the bottoms of the two sides; the turbine system is placed between the inner sides of the bottom of the door frame, and an axle is disposed at the center thereof, and both ends of the axle pass through the bearing housings at the bottom sides of the door frame And a first bevel gear is arranged at an end edge of the one end, and the inner surface of the hydraulic turbine is fixed with a plurality of blades along the axial direction thereof, and the blades have a curved curvature, and both are separated from the rim inward obliquely Set up and reserve appropriate clearance between the hub and the hub, and use the water flow of the river and the channel to radially impact the blade to drive the turbine to run, and prevent the debris in the water from being stuck between the blades; The rod system is erected on the outer side of the door frame, and a second bevel gear is arranged at the bottom thereof, and the second bevel gear train meshes with the first bevel gear on the turbine axle, so that it is driven to rotate with the turbine operation. The transmission is assembled on the top of the portal frame, and the drive shaft end is fixed to the top end of the transmission rod, and can be interlocked and matched by the internal gear ratio, and the transmission belt is driven to accelerate and rotate. The generator is fixed to the side of the transmission, and the power generating mandrel is coupled with the driven shaft of the transmission to rotate the power generating spindle of the generator to generate electricity. In this way, the door-shaped frame can be erected between the rivers and the banks, and the rivers and channels can be used to radially impact the blades to drive the turbines to operate, so that they can be driven and accelerated to drive the generators to generate electricity. Power generation efficiency, in order to effectively use natural water resources, fully in line with the trend of green energy and environmental protection.
