Compound high efficiency water turbine

Abstract

The invention relates to the technical field of water turbines and particularly a compound high efficiency water turbine. The water turbine comprises a housing; a main shaft is rotationally connectedin the housing; the top end of the main shaft is fixedly connected to the input shaft of a generator, the main shaft is rotationally connected to a turntable, the outer side of the turntable is fixedly connected with a connecting rod, and the end of the connecting rod is fixedly connected with a water bucket; the outer side of the housing is fixedly connected with a fixing seat, and the outer sideof the fixing seat is fixedly connected with an annular water pipe. The invention is applicable to hydroelectric power generation operations. The spraying device and the water bucket are arranged, and the water spray device impacts the water bucket through the water spray device to drive the spindle to rotate. The water storage tank and the vane are arranged, and the water flow is again used to impinge the vane by the water spray device to further drive the spindle to rotate. The flow meter and solenoid valve are set to protect the device by observing the inlet flow rate and adjusting the closing degree of the solenoid valve. The invention has simple operation, high utilization rate of water resources and multiple devices simultaneously drive the rotation of the main shaft, thereby improving efficiency and facilitating promotion.

Description

technical field [0001] The invention relates to the technical field of water turbines, in particular to a composite high-efficiency water turbine. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotating mechanical energy, and it belongs to turbomachinery in fluid machinery. Most modern hydro turbines are installed in hydropower stations to drive generators to generate electricity. In the hydropower station, the water in the upstream reservoir is led to the turbine through the water diversion pipe, which drives the runner of the turbine to rotate, and drives the generator to generate electricity. The finished water is discharged downstream through the tail water pipe. The higher the water head and the greater the flow, the greater the output power of the turbine. Turbine and auxiliary equipment are important hydropower equipment and an indispensable part of the hydropower industry. They are important equipment f...

Problems solved by technology

[0003] The water turbines currently in use, especially small water turbines, generally have the disadvantage of low water flow energy collection efficiency, and the water flow utilization rate is low. Most of them use a single water flow for a single impeller, and the power conversion rate is low.

[0004] Chinese patent (notification number: CN206917799U) discloses a high-efficiency water turbine power generation device, including gate valves, water channels, several water turbines installed on the water channel, speed changers, and generators. The bottom of the water channel is in a stepped structure; The hub, spokes, water bucket, baffle, the hub is composed of a hollow tube and a wheel; one end of the spoke is fixed on a wheel of the hub, and the other end extends out of the wheel; the two sides of the water bucket are respectively fixed on the spokes. At the end, each side is fixed by two spokes, and the number of water buckets can be increased or decreased according to the water flow; the baffle is fixed between two adjacent water buckets in a groove-like structure; the speed changer and generator are installed in turn on the water turbine The end of the main shaft, through the flow of water, drives multiple water wheels connected by belt transmission to rotate, thereby improving the use efficiency of the water flow and increasing the output power of the water turbine. However, this device is very dependent on the terrain and must be installed on an inclined waterway. The scope of application is relatively large. Small, and linked through the belt drive connection, the energy loss is large
