A hydraulic water intake system

Abstract

The invention discloses a hydraulic water taking system which comprises a water taking ditch. The hydraulic water taking system is characterized in that a water taking device is arranged at a water taking ditch inlet, and comprises a water taking cavity body; a water outlet located above the water taking ditch inlet is formed at one end of the water taking cavity body; a water outlet one-way valve is arranged at the water outlet; a water taking piston is arranged in an inner cavity at the other end of a water taking channel; a push-pull rod is connected and arranged outwards; a water inlet pipe is downwards communicated and arranged on the water taking cavity body; a water inlet one-way valve is arranged in the water inlet pipe; the outer end of the push-pull rod is in transmission connection with an impeller by a transmission mechanism; the impeller is mounted on an impeller shaft, and can rotate by virtue of driving of a water flow; an input end of the transmission mechanism is connected with the impeller shaft; and an output end of the transmission mechanism is connected with the outer end of the push-pull rod, and can drive the push-pull rod to make push-pull reciprocating motion. The hydraulic water taking system has the advantages that water taking can be performed by ingeniously utilizing energy carried by a river; operation is stable; the cost is low; a site selection requirement is lower; the quantity and the quality of taken water are more ensured; and cleaning of silt is facilitated.

Description

technical field [0001] The invention belongs to the field of river hydraulic engineering, and in particular relates to a hydraulic water intake system. Background technique [0002] The river bed water intake structure refers to the structure that uses the water inlet pipe to extend the water intake head into rivers and lakes to take water. composition. The water intake head is the water intake part of the riverbed-type water intake structure, and is the source of water intake for the water diversion pipeline. It is often built on the side of the river bank, and the water flow is controlled by laying gates. The site selection of the water intake should generally take into account the sedimentation of the river channel and the water intake requirements, so as to ensure that the source water can enter the diversion pipeline when the water level of the river channel is the lowest. [0003] Usually, the water intake can be arranged on the side of the river bank with less sedim...

AI Technical Summary

Problems solved by technology

[0003] Usually, the water intake can be arranged on the side of the river bank with less sediment accumulation (such as the concave bank of the curve), but the following problems also exist in the actual engineering: (1) relying on the water pump for water intake, which is dependent on and wastes electricity, and the water pump is prone to failure after long-term operation , poor water stability

(2) The construction of the pump house is limited by the sedimentation of the river channel, so it is difficult to select a site; at the same time, the construction of the pump house at the water intake destroys the original river channel boundary and has an impact on the river regime. The amount is reduced, making it difficult to meet the design water demand

(3) The water directly entering the diversion pipeline from the water intake is mixed with suspended sediment, which affects the water quality and causes congestion due to sediment deposition
