Device for starting side slope siphoning drainage system and method of device

Abstract

The invention discloses a device for starting a side slope siphoning drainage system and a method of the device. The device comprises a water tank, air discharge pipes and a drainage pipe, a water outlet of each siphon is formed in the sealed water tank, and an inlet of each air discharge pipe is connected to the top of the water tank; an inlet of the drainage pipe is connected to the bottom of the water tank, the vertical distance between the inlet of the drainage pipe and an outlet of the drainage pipe is larger than the height of a water column corresponding to the local atmospheric pressure, and the height difference between the top of the water tank and a hole opening of a drilling hole is larger than the height of the water column corresponding to the local atmospheric pressure. According to the device, by controlling opening and closing of the draining pipe, negative pressure is produced to start siphoning without the help of other equipment, and the device is simple and reliable; the vertical distance between the inlet of each air discharge pipe and an outlet of the corresponding air discharge pipe is larger than the height of the water column corresponding to the local atmospheric pressure, negative pressure is formed in the water tank, water in the air discharge pipes cannot enter the water tank, it is guaranteed that negative pressure in the water tank is not broken,and accordingly the stability of the whole device is improved; multiple siphons can be started simultaneously, and siphoning is started quickly and efficiently.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, in particular to a device and method for starting a slope siphon drainage system, which is used for quickly starting the slope siphon drainage system, and is especially suitable for a slope siphon drainage system that requires intermittent and repeated activation of the siphon action. Background technique [0002] Siphon is a physical phenomenon that uses the force of liquid level difference to promote liquid flow. The siphon flow process and flow rate are automatically controlled by liquid level changes. These physical characteristics are very suitable for slope drainage and have been promoted in slope drainage. application. [0003] The initial state of the siphon is full of air, and the siphon requires external force to fill the siphon with water. Under the gravity of the liquid in the downpipe, a negative pressure environment is formed at the top of the siphon, so that the water i...
