River pumping irrigation multifunctional scenery waterfall dam

Abstract

The invention discloses a river pumping irrigation multifunctional scenery waterfall dam which comprises river dam bodies constructed on one side or two sides along the river direction. A main overflow channel is formed at the top of each river dam body along the length direction of the same. Two auxiliary overflow channels lower than each river dam body are respectively constructed on two sides of the river dam body. Lotus-fish ponds are constructed on the outer side of each of the two auxiliary overflow channel. A protection net is disposed at the junction of each inner lotus-fish pond close to the river and the river. Each outer lotus-fish pond is communicated with a large field requiring irrigation through a water outlet. Water pumping devices such as a waterwheel are used to transfer water from the river to the main overflow channels. By the main and auxiliary overflow channels, the water running mode of 'one river two overflows' is formed, a natural scenery waterfall is formed by utilizing height of water, ecological environment is coordinated, air humidity is increased, coolness and warmness are optimized, and comfortableness of living environments is increased. The main and auxiliary overflow channels allow farmers to use the water flowing down to fight drought and irrigate fields and can distribute floods in the river.

Description

technical field [0001] The invention relates to the technical fields of river embankment ecological management, irrigation and flood control, in particular to a multi-functional landscape waterfall dam that utilizes river water lifting for irrigation. Background technique [0002] For the purpose of flood control and guiding the flow of water, river embankments are built on both sides of the river bank. The cost of building river dams is high, but its functions are relatively single. At present, there is no reasonable plan to comprehensively utilize river dams to meet the needs of tourism, ecology, irrigation, and flood discharge. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional landscape waterfall dam for water lifting and irrigation of rivers, which can meet the requirements of flood discharge and irrigation and form a landscape waterfall. [0004] For solving above technical problem, the ...
