Problems solved by technology

However, it is not an easy task to build and maintain flood drainage facilities in some inaccessible places. It is not only a modern flood control dam, but also needs to consume electric energy and start related large-scale mechanical equipment during flood drainage. So can a kind of Natural flood drainage facilities as a preventive protection against flood disasters

Embodiment Construction

[0009] Such as figure 1 According to the water storage volume of the dam body, a reasonable warning water level is selected, and a through hole is cut horizontally on the dam body at the warning water level to place the starting branch pipe. The starting branch pipe runs through the dam body. It is laid to the crest of the dam, and then laid from the crest to the bottom of the dam outside the dam. The start-up branch pipe is connected horizontally with the siphon outside the dam. The difference between the diameter of the start-up branch pipe and the diameter of the flood discharge siphon determines the start-up time. The larger the value, the slower the start-up time, and the smaller the diameter difference, the faster the start-up time, and the diameter of the flood discharge siphon needs to be selected according to the requirements of the flood discharge rate. A plurality of flood discharge siphon pipes can also be laid on a dam body as required.

Abstract

A zero-energy-consumption automatic flood discharge device for lake dam comprises a dam body, an inverted U-shaped siphon flood discharge pipeline, a starting branch pipe and a pressure valve plate and is characterized in that when the water level exceeds a warning water level, flood flows into a lower siphon pipe of the inverted U-shaped siphon flood discharge pipeline through the starting branch pipe, and the water level of the lower siphon pipe increases unceasingly; when the water level of the lower siphon pipe is higher than a siphon water level, the pressure valve plate is opened, water in the lower siphon pipe is discharged out and siphonage is initiated to occur, and at the moment, a great amount of flood is discharged from the inverted U-shaped siphon flood discharge pipeline; and when the flood level is lower than the warning water level, air enters the starting branch pipe quickly and arrives in the lower siphon pipe, and then siphonage is broken, so that flood discharge is finished automatically as soon as siphonage is finished. The whole process occurs and ends naturally, does not require manual operation and does not consume any energy.

Description

Technical field [0001] The invention relates to a flood discharge facility, in particular to an unattended flood discharge facility. Background technique [0002] At present, the design and construction of reservoir dams and embankments of rivers and lakes will definitely invest a lot of manpower and material resources in the prevention of natural disasters to ensure that nothing goes wrong. However, it is not an easy task to build and maintain flood drainage facilities in some inaccessible places. It is not only a modern flood control dam, but also needs to consume electric energy and start related large-scale mechanical equipment during flood drainage. So can a kind of The natural flood drainage facilities act as a preventive protection against flood disasters. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems and design the flood discharge facility, the zero-energy automatic flood discharge device of the la...
