Dredging device for canal gate

Technical Field

The utility model belongs to the technical field of canal gates, and particularly relates to a dredging device for a canal gate.

Background

Canal gates are low head hydraulic structures built into the canal body to control water flow and regulate water level. In practical application, if the water quality and the sand content of the channel controlled by the gate are poor, sediment accumulation is easily formed at the bottom of the channel at the upstream side of the gate, so that the control and regulation functions of the gate are greatly reduced, and unnecessary economic property loss can be caused.

The gate dredging device in the prior art is a dredging device of a canal gate, such as disclosed in an authorized bulletin No. CN 211773387U, wherein a collecting plate of the device is movably connected with the gate, when the gate is closed, the collecting plate is positioned at the bottom of a river channel to collect sludge, and when the gate is opened, the collecting plate and the gate lift out of the water together to carry out dredging work.

The prior art described above has the following drawbacks: the lifting of the collecting plate and the gate are synchronous, so when the gate needs to be opened without dredging, the collecting plate and the gate are lifted together, which causes unnecessary energy waste and mechanical abrasion, and a dredging device is needed in which the lifting of the collecting plate and the opening and closing of the gate can be separately carried out.

Further, both ends of the sludge collecting plate are respectively contacted with the inner side walls of the two vertical plates, and one end of the sludge collecting plate, which is close to the gate, is contacted with the gate.

Through making silt collecting plate contact with riser and gate respectively, the silt that will deposit of collection that can be better avoids silt to fall into on the diapire of canal body, influences the regulatory function of gate.

Further, the driving assembly comprises a winch, steel wire ropes and hinging seats, wherein the hinging seats are respectively arranged on four corners of the upper surface of the sludge collecting plate, the steel wire ropes are fixed on the hinging shaft of each hinging seat, the upper ends of the steel wire ropes are all wound on one winch, and each two winches are arranged at the top end of a corresponding vertical plate in a group.

Through setting up four hoists for pull corresponding wire rope and articulated seat and drive the silt and collect the board, when the silt that needs to clear up on the silt collection board, drive four hoists simultaneously, make silt collection board upwards remove to silt clearance hole, then carry out silt clearance, after silt clearance finishes, drive four hoists simultaneously, put down the silt collection board, make silt collection board drop to on the diapire of canal body, collect the silt that will deposit.

Further, the articulated seat includes bottom plate, two risers and articulated shaft, and the bottom plate sets up along the horizontal direction, and the bottom plate sets up on the upper surface of silt collecting plate, and two riser intervals set up on the upper surface of bottom plate, and the articulated shaft rotates to connect between two risers.

Through setting up articulated seat, can link together wire rope and silt collection board through articulated seat, every hoist engine makes silt collection board upwards or downwardly moving through corresponding wire rope of drive and articulated seat.

Further, two grooves are formed in the inner side wall of each vertical plate at intervals, the grooves are arranged in the vertical direction, the top ends of the grooves are close to the lower edge of the sludge cleaning hole, two limiting plates are arranged at the two ends, in contact with the inner side wall of each vertical plate, of each sludge cleaning plate, and each limiting plate is arranged in one groove in a sliding mode.

Through set up recess and slip limiting plate that sets up in the recess on the inside wall of two risers for inject the direction of movement of silt collecting plate, make silt collecting plate can more steady rise or descend, through the position of control every recess upper end, make silt collecting plate can rise to silt clearance hole, recess and silt clearance hole do not link up, the lower extreme of every recess extends to on the diapire of canal body.

The beneficial effects of the utility model are as follows:

1. through setting up silt collecting plate and being used for driving the drive assembly of silt collecting plate, make the lift of silt collecting plate and gate go on separately, overcome among the prior art, when not needing desilting but needing to open the gate, the collecting plate still goes up and down with the gate synchronization's drawback, so has the advantage of energy saving.
