Sprocket wheel watermill

Abstract

The invention discloses a chain wheel water mill, comprising a bracket, a power mechanism and a lifting mechanism; the power mechanism comprises two chain wheel groups arranged vertically, a plurality of large water boxes are distributed uniformly between the chain wheel groups and one end of the large water box opposite to the moving direction of the chain wheel is opened; the lifting mechanism comprises two chain wheel groups arranged vertically, a plurality of small water boxes are distributed uniformly between the chain wheel groups and the end surface of the small water box same with themoving direction of the chain wheel is provided with a water inlet which is positioned at the side far away from the chain; one side of the small water box which is adjacent with the end face of the water inlet and is near to one side of the chain is provided with a water outlet; an upper chain wheel of the power mechanism is connected with a lower chain wheel of the lifting mechanism by a transmission mechanism in a transmission mode; the chain wheel group of the power mechanism is lower than the chain wheel group of the lifting mechanism and in unit time, the reduced potential energy causedby the decreased water contained in the large water box of the power mechanism is larger than the increased potential energy caused by the lifted water contained in the small water box of the liftingmechanism. The invention does not need to add energy externally, completes the function of lifting the water by using the water mill and realizes irrigation or power generation.

Description

technical field [0001] The invention relates to a water conservancy equipment for lifting water upwards, in particular to a sprocket water wheel, which is mainly suitable for farmland irrigation, water supply, etc., and can also be used for power generation. Background technique [0002] Waterwheels, also known as overturned carts, were used by people as early as the Later Han Dynasty. In the Tang Dynasty, they generally appeared beside various rivers and ditches. They raised water at low water levels and introduced them into the canals for irrigation of farmland. The early waterwheels were all human-pedaled. With the development of science and technology, waterwheels using electricity, diesel engines, gasoline engines, etc. as power sources appeared. , mountainous areas or areas lacking power are not fully applicable. [0003] In response to the above problems, there have been water trucks that use the kinetic energy of the water flow to pump water. As the Chinese utility ...

Problems solved by technology

[0004] However, since the chain of the above-mentioned waterwheel is arranged in parallel with the water flow, its power is generated by the water flow pushing the water-retaining fan blades. Therefore, the waterwheel has high requirements on the flow velocity of the water flow, and is not suitable for occasions where the flow velocity of the water flow is low; At the same time, the power generated by the water flow pushing the water-retaining fan blades is very limited, and the water level is not raised high enough to be practically applied

[0005] In order to obtain higher kinetic energy, people usually use the method of building dams, which do not require additional energy, and can directly use water storage to irrigate farmland or realize hydropower generation. It can be said to kill two birds with one stone. , aquatic animals, etc., and at the same time solve and resettle immigrants, so there has been a global opposition to the construction of large dams in recent years; for some tributaries or small rivers, the construction of small dams has little impact on the environment, but Its water storage capacity is limited, the water level and water level difference are low, and direct irrigation cannot be realized. When used for power generation, only low-head, high-flow hydroelectric generators can be used, and even power generation cannot be performed.
