Dredging device for water conservancy construction

Abstract

The invention discloses a dredging device for water conservancy construction. The dredging device comprises a support column. A driving motor is fixedly arranged on the upper wall of the support column. The upper wall of the support column is fixedly connected with a water storage tank. A water inlet pipe is arranged on the upper wall of the water storage tank in a communicated manner. A water absorbing mechanism is arranged in the water storage tank. The water absorbing mechanism comprises a water absorbing disc fixedly connected to the inner wall of the water storage tank. An annular cavityis formed in the water absorbing disc. A circular groove is formed in the side wall, far away from one end of the driving motor, of the water absorbing disc. Two stop blocks are symmetrically arrangedin and fixedly connected with the interior of the annular cavity. The interiors of the two stop blocks are communicated with the circular groove through one-way channels. The side walls of the two stop blocks are elastically connected with magnetic sliding plugs through reset springs. Water inlets are correspondingly formed in the inner walls, close to the two sides of the two baffles, of the annular cavity. One-way valves are correspondingly arranged in the four water inlets. By the adoption of the dredging device for water conservancy construction, the transportation difficulty of the device is reduced, the economic cost and the electric energy are saved, the more abundant cleaning means is provided, and the cleaning effect is better.

Description

technical field [0001] The invention relates to the technical field of water conservancy construction, in particular to a dredging device for water conservancy construction. Background technique [0002] Now, my country's water conservancy construction is becoming more and more developed. By building water conservancy projects, controlling water flow and preventing floods, it has brought great protection to people's happy life. In water conservancy projects, it is usually necessary to use some water conservancy pipelines. During the use of water conservancy pipelines, the pipeline mouth is often blocked due to the accumulation of some sundries and silt, which brings great inconvenience to the smooth implementation of water conservancy projects. Therefore, it is necessary to periodically clean the silt at the pipeline mouth Desilting and dredging the debris attached to the inner wall of the pipeline, thereby preventing the blockage of the pipeline. However, the existing dredgin...

Problems solved by technology

[0003] 1. The drive of the existing dredging device requires not only the motor, but also the water pump to pump water into the pipeline, which makes the equipment of the whole device too complicated and difficult to transport, and also makes the economic cost of the whole equipment higher. The motor and water pump At the same time, it also needs to consume too much power;

[0004] 2. The existing dredging devices are generally driven by a motor to drive the rotating shaft to rotate, and then drive some cleaning mechanisms to rotate to dredge the inner wall of the pipeline. However, during the construction of water conservancy projects, many debris such as cement adhere On the inner wall of the pipeline, these sundries are difficult to scrape off only by this single rotation, and the dredging effect is not good.
