A water conservancy desilting device

Abstract

The invention discloses a water conservancy dredging and solidifying device, which comprises a silting cage installed on the walking equipment and driven to rotate in the water channel, a telescopic disturbance and crushing mechanism is installed in the silting cage, and the telescopic disturbance and crushing mechanism It is installed on the silting pipe coaxial with the silting cage, and the silting pipe is provided with silting holes along its axial interval, and the side wall fixing mechanisms are respectively movable and installed at both axial ends of the silting cage. , the end of each side wall fixing mechanism away from the side wall of the water channel is movably connected with a crushing degree adjustment mechanism for pressing the axial end of the telescopic disturbance crushing mechanism. The crushing degree adjusting mechanism and the side wall fixing mechanism are interlocked, An adjustment cavity is formed between the two, and the adjustment cavity expands and contracts along the axial direction of the silt cage due to changes in water pressure. The invention dredges the canal and discharges the silt, plants and garbage at the bottom of the canal at one time, reduces labor intensity and saves cost input. The invention is applicable to the technical field of water canal pollution control.

Description

technical field [0001] The invention belongs to the technical field of water canal pollution control, and in particular relates to a water conservancy dredging and solidifying device. Background technique [0002] Farmland irrigation often uses water from rivers and rivers, which is introduced into farmland through "ditches" opened on the ground, that is, canals. Due to the random discharge of pollutants into the canal, the canal is blocked, at least the circulating water of the canal becomes non-circulating water, so that the floating plants and algae on the water surface cover the entire water surface, which in turn causes the problem of eutrophication. Causes changes in water quality, which is not conducive to water storage and irrigation. Most of the existing cleaning methods are done manually, or the floating plants and the silt at the bottom of the canal are gradually salvaged by machinery, that is, the silt is cleared out of the canal by hand or an excavator.

Problems solved by technology

Due to the random discharge of pollutants into the canal, the canal is blocked, at least the circulating water of the canal becomes non-circulating water, so that the floating plants and algae on the water surface cover the entire water surface, which in turn causes the problem of eutrophication. Causes changes in water quality, which is not conducive to water storage and irrigation

Most of the existing cleaning methods are done manually, or the floating plants and the silt at the bottom of the canal are gradually salvaged by machinery, that is, the silt is cleared out of the canal by hand or an excavator. Although the silt at the bottom of the canal is removed in this way, the dredging operation is time-consuming Laborious and costly
