Abstract
A flood control and drought relief method involving building a group of extensible water retaining dams on a river. The extensible water retaining dam comprises a dam body (1), a wheel (2), a driving motor (3), a guide rail (4), a controller (5), and a water level sensor (6). When it is raining heavily in an upstream region, the water level sensor (6) at a downstream region senses that a water level rises, and transmits information to the controller (5), and the controller (5) controls the driving motor (3) to drive the water retaining dam to open to the maximum, such that flood peak waters easily pass therethrough. If the water level is still at a dangerous level when the water retaining dam in the downstream region has opened to the maximum, a water retaining dam in the heavily raining region upstream extends so as to reduce the flow of water arriving from the upstream region, thereby reducing the water level in the downstream region. After the flood peak waters pass through the downstream region, the water retaining dam in the upstream region returns to a normal degree of opening. When it is raining heavily in the downstream region, the water retaining dam in the upstream region extends to reduce the flow of water arriving from the upstream region, thereby reducing the water level in the downstream region. After the flood peak waters leave the downstream region, the water retaining dam in the upstream region returns to the normal degree of opening. After each flood season, the degree of opening of the water retaining dam is reduced to the minimum, such that the water level remains at the highest height, so as to achieve drought relief.

发明内容Summary of the invention
本发明的目的是提供一种在江河上建筑伸缩拦水坝群防洪抗旱的方法。The purpose of the present invention is to provide a method of flood control and drought resistance for building retractable dam groups on rivers.
上述伸缩拦水坝由坝体1、轮子2、驱动电机3、导轨4、控制器5、水位传感器6组成。The above-mentioned telescopic dam is composed of a dam body 1, wheels 2, a drive motor 3, a guide rail 4, a controller 5, and a water level sensor 6.
上游出现暴雨时，下游水位传感器6感应到水位上升向控制器5发出信息，控制器5控制驱动电机驱动拦水坝1打开至最大。让洪峰顺利通过。如果下游拦水坝开至最大，水位还是处在危险高度时，暴雨区上游拦水坝伸出减少上游流量，从而降低下游水位。下游洪峰过后，上游拦水坝恢复正常开口。When a heavy rain occurs upstream, the downstream water level sensor 6 senses that the water level rises and sends a message to the controller 5, which controls the drive motor to drive the dam 1 to the maximum. Let Hong Feng pass smoothly. If the downstream dam is opened to the maximum and the water level is still at a dangerous height, the upstream dam in the rainstorm area extends to reduce the upstream flow, thereby reducing the downstream water level. After the downstream flood peak, the upstream dam resumed its normal opening.

每年汛期之后，拦水坝开口缩至最小，让水位保持在最高，以到达抗旱目的。After the annual flood season, the opening of the dam is minimized to keep the water level at the highest level to achieve the purpose of drought resistance.
