Description

A clear water diversion device based on siphon principle

technical field

The utility model belongs to the technical field of water diversion and discharge, in particular to a diversion device for automatically regulating the flow and interval based on the siphon principle.

Background technique

Water diversion refers to the installation of ditches, pipes, etc. at key nodes such as rivers, rivers, and ditches as diversion tributaries for water diversion. Currently, gates, weirs, float valves and other equipment are used to automatically or semi-automatically divert water at diversion nodes. The control needs to consume kinetic energy and the construction cost is high.

In mountainous and semi-mountainous water source villages, there are contradictions between rural water use, sewage discharge and source clean water protection. The diversion of clean water is to meet the downstream rural production and domestic water needs, to save the source of clean water to the greatest extent through the villages, to reduce the discharge of sewage in the villages, and to regulate the water volume to meet the agricultural production water use. For this reason, according to the requirements of water diversion purpose, flow accuracy, time accuracy and data timeliness, a clear water diversion device that can realize automatic operation without energy consumption around the clock, has strong economic applicability, and is easy to maintain and manage.

Utility model content

The purpose of the utility model is to solve the above problems and provide a clear water diversion device based on the siphon principle with good clear water diversion effect.

In order to achieve the above object, the utility model adopts the following technical solutions: a clear water diversion device based on the siphon principle of the utility model includes a reservoir, a water inlet, and a water inlet valve, and the reservoir is provided with an overflow pipe , an inverted U-shaped siphon and a lifting mechanism, the overflow pipe includes an overflow pipe water inlet, a corrugated hose and an overflow pipe outlet, the overflow pipe water inlet is connected with the lifting mechanism, and the inverted U-shaped The installation height of the type siphon is lower than that of the water inlet, the length of the outer siphon of the inverted U-shaped siphon is longer than the length of the siphon in the pool, the outlet of the overflow pipe is arranged at the bottom of the reservoir, and the outlet of the overflow pipe is connected to the The clear water ditch is connected, and the outlet of the inverted U-shaped siphon is connected with the village ditch.

Further, the installation position of the inverted U-shaped siphon is 40 cm from the top of the reservoir.

Further, the mouth of the siphon in the U-shaped siphon is 15cm away from the bottom of the pool.

Furthermore, the slope at the bottom of the reservoir forms an included angle of 5 degrees with the horizontal line.

Further, the volume of the reservoir is equal to the water storage capacity of the village ditches.

The working principle of the clear water diversion device based on the siphon principle:

The reservoir stores clean water from the upstream source of the village, and a large-diameter water inlet is used to transport clean water into the reservoir. A water inlet valve is installed on the large-diameter water inlet to adjust the flow of clean water.

An overflow pipe with water inlet from the upper part and water outlet from the bottom is installed in the reservoir. The outlet of the overflow pipe drains to the clear water ditch. The height of the water inlet of the overflow pipe can be adjusted. When the height of the water inlet of the overflow pipe is higher than the highest point of the inverted U-shaped siphon When the reservoir is full of water, the siphon effect occurs, and the clear water in the reservoir is drained from the inverted U-shaped siphon into the village ditch; when the height of the overflow pipe inlet is lower than the highest point of the U-shaped siphon, the clear water in the reservoir It is discharged from the overflow outlet and re-enters the clear water ditch to reduce the clear water entering the village and avoid secondary pollution.

Beneficial effects: the utility model has a good clear water diversion effect. It diverts the clear water at the source of the upstream of the village. By adjusting the height of the overflow pipe, the clear water in the reservoir can flow back to the clear water ditch to save the clear water at the source and protect the water quality. The clear water is discharged through a siphon, and the accumulated clear water with large volume and high potential energy is discharged into the village ditches, which has the effect of flushing and cleaning the village ditches, and at the same time supplements the clear water of the village ditches to meet the water demand for agricultural production and domestic use.
