AI Technical Summary

Technical Problem

Existing hydraulic turbine devices for energy recovery cannot adjust when the water flow is too large, affecting the output stability of the output shaft and leading to unstable operation.

Method used

The system employs a pressure relief assembly and a stability detection assembly in conjunction with a processing module. An infrared detector monitors the stability data of the drive shaft in real time, automatically adjusting the opening and closing of the pressure relief assembly to ensure that the drive shaft operates within a suitable and stable range. Simultaneously, the system controls the water flow into the No. 1 tank for discharge by adjusting the sealing plate and sealing ring through a support frame and an electric telescopic rod. Furthermore, a noise reduction assembly reduces the impact force and noise of the water flow.

Benefits of technology

This technology improves the stability of the output shaft when the water flow is too large, increases energy recovery efficiency, reduces maintenance time and noise, and optimizes the operating environment.

Abstract

This invention discloses a low-noise energy recovery hydraulic turbine device. The invention relates to the field of hydraulic turbine technology and includes a housing, an inlet, an outlet, a turbine rotor, a turbine stator, a drive shaft, a pressure relief pipe, and a pressure venting assembly. The inlet and outlet are installed through the outer wall of the housing, the turbine stator is installed on the inner wall of the housing, and the drive shaft is installed through the outer wall of the housing via bearings. The invention utilizes a first support frame to provide support for a first support cylinder. The movement of the electric telescopic rod moves the top head, which in turn moves the sealing plate. The sealing plate then moves the first support rod, causing the sealing plate to move the sealing ring. This movement allows the sealing ring to move away from the support ring, allowing water to flow through the pressure relief pipe into the first tank for discharge. This effectively prevents excessive water flow within the hydraulic turbine device and improves output stability.
