Horizontal gate bed silt flushing device in tidal area

Abstract

The invention relates to the technical field of sewage disposal equipment and discloses a horizontal gate bed silt flushing device in a tidal region. The horizontal gate bed silt flushing device comprises two fixing blocks, wherein opposite sides of the two fixing blocks are provided with shells, and the shells are internally provided with trash holding grilles; difference between upstream and downstream water heads is utilized, a large-flow low-water-head is adopted for silt flushing, the silt flushing device is different from a conventional silt flushing device which adopts a pump and a nozzle to generate a small-flow high-water-head for jetting and desilting, the silt flushing device adopts a bilateral self-water-diversion suspension pipe arrangement scheme, water inlet facilities are arranged on the left bank and the right bank of the upstream side of a water gate respectively, water diversion is conducted from the upstream side, and control is conducted through a gate valve; the device penetrates through the gate bottom plate in a pipe burying mode and is led to the gate hole, the nozzle sprays water flow and disturbs silt in a pipe hanging mode, a desilting purpose is achieved, and compared with an existing conventional device, the desilting effect is better, and compared with an existing desilting device, the device is more energy-saving.

Description

technical field [0001] The invention relates to the technical field of sewage discharge equipment, in particular to a flushing and silting device for a horizontal gate bed in a damp area. Background technique [0002] The horizontal gate has a large discharge capacity and is a common gate type in water conservancy projects. However, the lower horizontal gate bed is prone to deposits, especially in tidal areas. When the gate is closed, the lower part of the gate and its surroundings will It will be silted by suspended matter. When the suspended matter silts to a certain height, it will hinder the opening and normal operation of the gate. Therefore, it is necessary to set up washing and silting equipment to regularly and effectively wash and silt, so that the gate can operate safely, flexibly and easily. In the actual application of engineering, the scouring and silting system mostly uses high-pressure nozzles to impact the silt in front of the gate or in the flow channel, dis...
