A water conservancy power generation and irrigation device that uses resonance to remove sand and gravel to prevent wear

Abstract

The invention discloses a hydraulic power generating and irrigating device adopting resonance to remove sand and prevent abrasion. The hydraulic power generating and irrigating device structurally comprises a water inlet pipeline, irrigating pipelines, a connecting flange, an irrigating water tank, a controller, supporting foot seats, and a sand removing and power generating device. A rotating shaft drives a linkage ring to rotate, and therefore a filter screen attached to the rugged outer side of the linkage ring shocks up and down. Resonance is generated under deformation resilience force ofa rubber ball and a connecting strip, and therefore sediment accumulated above the filter screen moves to the left under the inertia force and the driving force of the water current. Filter screen blocking is prevented. The water current penetrates through the fine filter screen for further filtering, abrasion caused by sediment impact to the surface of a driving impeller is prevented, and service life shortening is prevented. The water current is buffered by a buffering pad and a groove block, and therefore the water current passes through the surface of a defloating pad at a moderate flow rate to increase the residence time, floating wadding removing in the water current is facilitated. Floating wadding entering rotating clearance of the driving impeller and accelerating abrasion is prevented, and a mass of floating wadding blocking the irrigating pipeline is prevented.

Description

technical field [0001] The invention relates to the field of hydropower generation, more precisely, a hydropower generation and irrigation device that utilizes resonance to remove gravel and prevent abrasion. Background technique [0002] With the development of the economy, people's demand for electricity is constantly increasing, and the environmental pollution caused by thermal power generation is too serious, which makes the more environmentally friendly and effective hydropower generation popularized and developed, which converts the kinetic energy of water into mechanical energy. , the existing traditional technology is not considered comprehensively, and has the following disadvantages: [0003] Most of the water resources used by hydropower come from groundwater and river water. Due to long-term sediment accumulation, the water contains a large amount of sediment. Although a filter is installed at the inlet, due to the large amount of sediment, it is easy to Blockag...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a hydroelectric power generation and irrigation device that utilizes resonance to remove sand and gravel to prevent abrasion, so as to solve the problem that most of the water resources used in hydropower generation in the prior art come from groundwater and river water. Due to long-term The accumulation of sediment makes the water contain a lot of sediment. Although there is a filter screen at the inlet, due to the large amount of sediment, if the filter screen aperture is small, it will be easily blocked, resulting in a decrease in water volume and power generation efficiency. If the filter screen aperture is too large If it is too large, it is easy to make sediment mixed with water, and the water flow mixed with sediment will quickly and vigorously impact the paddle wheel of the power generation under the force of gravity. The sediment will scratch the surface of the paddle wheel and aggravate the defect of paddle wheel wear.
