Sludge extraction device used for river restoration based on Bernoulli principle

Abstract

The invention relates to the technical field of river restoration, and discloses a sludge extraction device used for river restoration based on the Bernoulli principle. The sludge extraction device used for river restoration based on the Bernoulli principle comprises a ship body, an extraction head comprises a first arc groove, a rectangular magnet, a hanging ring, a second arc groove and an annular groove, the outer side of the lower portion of the extraction head is provided with a grid plate, the inner side of the middle of the extraction head is connected with a rotating ring, an inclinedfan is arranged on the inner wall of the inner side of the rotating ring, convex balls are arranged on the outer side wall of the rotating ring, the inner part of the extraction head is connected witha swing rod, the spherical magnet is arranged at the inner side end of the swing rod, a spiral thread is arranged on the upper end face of the rotating ring, and the inner side end of the guide rod is connected with a plugging plate. According to the sludge extraction device used for river restoration based on the Bernoulli principle, a fluid pushes the inclined fan to drive the rotating ring torotate, the rotating ring drives a sliding rod to extend outwards through the convex balls, the sliding rod pushes the swing rod so that cleaning impurities on the outer side of the grid plate can becarried out, and the structure solves the problems that the existing river sludge extraction device cannot perform cleaning to the impurities and the cleaning position cannot be changed.

Description

technical field [0001] The invention relates to the technical field of river restoration, in particular to a river restoration sludge extraction device based on Bernoulli's principle. Background technique [0002] Ecological river management refers to promoting the restoration of the river water ecosystem through artificial restoration measures and building a healthy, complete and stable river water ecosystem within the land control line of the river, on the basis of satisfying the basic functions of the river, such as flood control, drainage and water diversion. activity. The ecological management of river courses involves different river sections and different functions, and the degree of attention to each function and the time to be repaired are not the same. Therefore, the priority of ecological river management should be determined first. It should be noted that the restoration project It is not always necessary to start with the most damaged section of the river, some...
