I CLAIM
1. A redesigned dam siphon featuring ability to drain out the water below penstock level enabling to carry out repair and maintenance works on the bottom layer of the dam structure which feature is not currently available nor attempted for. The siphon is characterized by
• Overall device with an inverted 'V shape.
• Head of siphon (a box vent), fitted to the two sides of siphon by nuts and bolts, used to fill water in the siphon without air pockets.
• A movable siphon (suction side) for intake of water, end of which is devised with a feature to move down with the gradual depletion of water level so that it remains immersed in the water throughout the decanting process and provided with a upward open valve at the end
• A fixed siphon (delivery side), end of which is set to route the water to desired destinations.
2. The redesigned dam siphon as claimed in claim 1, enables utilization of currently unutilized and left stagnated below the penstock level, to be utilized for routing to canals and power stations. The end of delivery side of the siphon is designed to route the water to desired destinations. The process of decanting can be controlled to avoid sedimented impurities etc. to be drawn using the feature of Head of siphon which when opened the process is terminated.
3. The redesigned dam siphon as claimed in claim 1, provides for the suction side to move down along with the depletion of water level during the decanting process so that the end of suction side remain immersed in water throughout the process. The movable portion with a diameter size lesser than.the outer fixed portion is inserted into the outer fixed one. Two oil seals and oil enables the moving of the inner portion possible. It has two threaded shafts, gear box and motor to control the movement i.e. whenever water level reduces the inner movable portion goes down and keeps itself immersed in water.
4. The redesigned dam siphon as.claimed in claim 1, applies gravity force instead of fuel dependent mechanical technology to commence and terminate the functioning of the device.
A long steel pipe is set at delivery (outlet) side. It has an end cap made of tempered glass. It can be opened instantly in a second. To make the siphon system function, the end cap of delivery side is broken using a minimal explosion mechanism that causes water to flow upward from the suction side and raise through the siphon by means of the gravity force and flow out through the delivery side of the siphon.
