Problems solved by technology

[0003] In water conservancy projects, the way of laying pipelines is often used to transport water. In order to facilitate the dredging of the silt in the pipeline, the motor is often used to drive the helical blade to rotate in the pipeline to achieve the purpose of dredging the pipeline. However, after the helical blade is buried by the silt, when the motor is started, The motor is easy to fail to start normally due to excessive starting load, and it is easy to be damaged when forced to start, which affects the service life of the motor

Abstract

The invention relates to the technical field of water conservancy projects, in particular to dredging equipment for a water conservancy project, comprising a support, a motor mounted on the upper surface of the horizontal part of the support, a driving shaft fixedly connected to the output end of the motor through the support, a round cover fixedly connected to the lower end of the cylinder, and around box mounted on the lower surface of the round cover. A first gear and a second gear which are meshed with each other are installed in the round box, a connecting column is fixedly connected tothe upper surface of the first gear, a first square hole is formed in the middle of the face, away from the motor, of the driving shaft, a square rod is inserted into the first square hole, and a second square hole matched with the square rod is formed in the face, away from the first gear, of the connecting column. Compared with the prior art, the motor no-load starting device has the following beneficial effects that no-load starting of the motor is achieved, and the motor is prevented from being started in a large-load state.

Description

technical field [0001] The invention relates to dredging equipment for water conservancy projects, which belongs to the technical field of water conservancy projects. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. [0003] In water conservancy projects, the way of laying pipelines is often used to transport water. In order to facilitate the dredging of the silt in the pipeline, the motor is often used to drive the helical blade to rotate in the pipeline to achieve the...
