Trash blocking device for water inlet of pumped storage power station

By adding the rotation of the motor drive thread column in the water inlet of the pumped storage power station to change the inclination angle of the current limiting plate and the relative separation transmission method, the blockage, water purification effect and jamming caused by the fixed spacing of the stain-blocking grid are solved. It realizes control of flow rate and sewage discharge accuracy and motor safety protection.

AI Technical Summary

Technical Problem

The spacing between the dust blocking devices of existing pumped storage power stations is fixed, resulting in smaller-sized debris blockage and reduced water purification effect, and may cause stuck during cleaning, damage to the motor and stagnant work.

Method used

A device including a body of a dirt blocking device, a barrier plate, a waterproof box, a motor, a transmission gear and a rubber rod is designed. By controlling the rotation of the motor drive thread column, the inclination angle of the current limiting plate is changed, the water flow rate and the discharge accuracy are controlled, and the relative The separate transmission method avoids the motor stagnation in the event of jamming and ensures the stable operation of the device.

Benefits of technology

Effectively control the flow rate and discharge accuracy, avoiding the problem of difficult control of the flow rate and discharge accuracy of the original device, and protecting the motor when it is stuck, ensuring the service life and safety of the device.

Abstract

The invention belongs to the technical field of hydropower station garbage cleaning, and particularly relates to a pumped storage power station water inlet trash holding device which comprises a trash holding device body, two sets of baffles are welded to the top end of the trash holding device body, a waterproof box is installed at the bottom between the two sets of baffles, and a second motor is arranged in the waterproof box. The output end of the second motor is connected with a threaded column, five sets of fourth transmission gears are rotationally connected to the outer portion of the threaded column, and one side of each fourth transmission gear penetrates through the waterproof box to be fixedly connected with a current limiting plate. A first motor is arranged at the top end of the operation bin, and the output end of the first motor penetrates through the operation bin and is in welded connection with a driving gear; the inclined angle of the flow limiting plate is changed by controlling the motor to drive the threaded column to rotate, so that the flow speed of water flow is controlled, the sewage discharging precision can be controlled, and the problem that an original device is high in difficulty in controlling the flow and the sewage discharging precision is solved.
