AI Technical Summary

Technical Problem

The existing automated cleaning devices for water conservancy gates are independent of the opening and closing systems, which increases equipment costs and energy consumption. They also have poor linkage, complex structures, and high failure rates, making them unable to effectively clean floating objects and sediments in rivers and lakes.

Method used

The system combines a transmission component with a collection component. The gate is raised and lowered by a motor-driven first bevel gear set and a threaded rod, while a pneumatic cylinder drives the movement of the collection component. Combined with a funnel-shaped feed inlet and a detachable receiving space, it achieves automated cleaning of contaminants.

Benefits of technology

It achieves efficient and automated cleaning of pollutants, reduces equipment costs and energy consumption, improves the linkage and stability of the structure, and ensures the normal opening and closing of the gate and the ecological safety of the water body.

Abstract

This utility model discloses a water conservancy gate with pollutant cleaning function. It belongs to the field of water conservancy gate technology and includes a dam body and a support frame. A gate frame is located in the middle of the dam body, and a motor is installed on the top of the gate frame. A connecting plate is slidably connected inside the gate frame, and the gate body is fixedly connected to the bottom of the connecting plate. A first bevel gear set is connected downwards to the output end of the motor. A first threaded rod is connected to the bottom of the first bevel gear set via a rotating shaft. The first threaded rod is threadedly connected to a threaded sleeve. The support frame is fixedly connected above the dam body. One side of the first bevel gear set is connected to one end of a support rod via a rotating shaft. One end of the support rod extends into the support frame and is connected to a second bevel gear set. This device solves the problem that in some current gate systems, the cleaning components and the gate opening and closing system are independent, requiring an additional power source and increasing cost and energy consumption.
