The intelligent through flow turbine comprises a filter mechanism, a water guide pipe and a water inlet pipe; the filter mechanism includes a third driving motor, a driving wheel, a second pulley, a first lifting wire and a filter unit; the filter unit includes a pull rod, a filter screen and two connecting modules; a guide chamber is formed below the water guide pipe; and a guide mechanism is arranged in the guide chamber, and includes a second driving motor, a first connecting rod, a second connecting rod, a slide block and a support frame. The intelligent through flow turbine with safety, reliability and excellent performances uses the filter screen for effectively isolating impurities in water currents, uses the filter mechanism for driving the filter screen to ascend through monitoring flow data, is convenient for removing the impurities, guarantees normal operation of a power generation mechanism, and has improved safety and reliability; and in addition, a guide plate upwards rotates through the guide mechanism, so that the contact area between the water currents and blades is increased, the work of the water currents applied on the blades is improved, and the excellent power generation performance of the water turbine is guaranteed.

Description

technical field [0001] The invention relates to the field of hydraulic power generation equipment, in particular to an intelligent tubular water turbine with safety, reliability and excellent performance. Background technique [0002] Tubular turbines are suitable for water heads of 1-25m. The water flow is straight. It is a horizontal axis turbine. The shape of the runner is similar to that of the axial flow runner, similar to the blades of an electric fan. Tubular turbines also have fixed paddles and There are two kinds of paddles. Because the water flow basically moves in the circumferential direction without turning, the water passing capacity and hydraulic efficiency of the unit can be improved. Tubular turbines have good hydraulic performance both as turbines and as water pumps, and are especially suitable for tidal power stations. Their two-way power generation, two-way pumping and two-way discharge functions are very suitable for comprehensive utilization of low-hea...

Problems solved by technology

[0003] Similar to the working principle of a wind turbine, the working principle of a tubular turbine is that the water flowing in the pipeline drives the blades to rotate, and after being accelerated by the gearbox, it drives the generator to rotate and generate electricity, realizing the effect of converting mechanical energy into electrical energy. During the flow process, when the water flow rate is small, the water flow is affected by gravity and flows at the bottom of the pipe. At this time, the water flow only contacts or even does not touch the bottom of the blades, resulting in a small amount of work done by the water flow on the blades, resulting in a decrease in speed, thereby reducing the power generation efficiency. Not only that, after the existing tubular water turbine is introduced into the water flow, due to some large impurities such as stones and garbage in the water flow, these garbage impurities are easy to get stuck on the blades when the water flows through the blades of the turbine, causing the blades to not rotate. , affect the safe operation of the equipment, so that the water turbine cannot work normally, resulting in a reduction in the practicability of the water turbine
