Device for converting gravitational potential energy into rotational energy

Abstract

The invention discloses a device for converting gravitational potential energy into rotational energy, and belongs to the field of urban energy saving and water resource recycling comprehensive utilization. The device comprises a water turbine, a water turbine spindle serves as a center and is sequentially sleeved with a rainwater pipe, a second-floor sewage pipe and a first-floor sewage pipe in sequence from interior to exterior, the bottom of the water turbine spindle is sequentially connected with an upper layer impeller, a middle layer impeller and a lower layer impeller in sequence from top to bottom, the lower-layer impeller is arranged in an annular channel between the extension face of the outer wall face of the second-floor sewage pipe and the inner wall face of the first-floor sewage pipe, the middle-layer impeller is arranged in an annular channel between the extension face of the outer wall face of the rainwater pipe and the inner wall face of the second-floor sewage pipe,the upper layer impeller is arranged in an annular channel between the inner wall face of the rainwater pipe and the outer wall face of the water turbine spindle, and the top face of the rainwater pipe is higher than the upper layer impeller by 3.2 m or above. Scattered untime discontinuous drained rain sewage gravitational potential energy is recycled and is converted into the rotational energy,a distribution power station can use the device, and the device is small in investment, convenient to mount and compact in arrangement. The efficiency for converting gravitational potential energy into rotational energy is 75%.

Description

technical field [0001] The invention belongs to the fields of energy saving, emission reduction and resource recovery comprehensive utilization in rural areas, towns and cities, and in particular relates to a gravity potential energy conversion rotational energy device suitable for recovering rainwater and domestic sewage gravity potential energy and converting it into rotational kinetic energy for use. Background technique [0002] With the increasing scarcity of water resources and the increasing awareness of people's environment, the recycling of rainwater and domestic sewage such as household kitchen, bathroom washing and other domestic miscellaneous drainage has become a topic of concern. [0003] Rainwater is usually used for fire fighting, environmental landscape, car washing, water storage for toilet flushing, cooling water replenishment and other domestic miscellaneous water. Domestic sewage is usually used to flush toilets. A large number of used rainwater sewage ...
