Description
Technical Field
The invention relates to the technical field of dredging equipment, in particular to a dredging device for a water conservancy facility.
Background
The more common general of hydraulic facilities includes the dam, the drainage canal, aqueduct etc. or equipment relevant with it, drainage canal or aqueduct are used for agricultural irrigation more, generally set up the sluice that is used for the segmentation regulated water yield more at the canal water course, the department that opens and shuts of sluice especially blocks the upstream face bottom of rivers direction and often can pile up the silt that many impurity constitute, silt not only influences the normal switching of sluice, still can block up the water course, the sluice that currently generally distributes is mostly whole board-like sluice that vertical slip opened and shut, the peripheral dam body of sluice corresponds the side and the bottom sets up corresponding spout, sluice bottom or side generally set up deformable stagnant water board, stagnant water board adopts rubber class material or changeable metal to make to be used for and dock realization sealing and water blocking effect with the recess of sluice dam body bottom more.
The silt of general soft mud class piles up and can be broken up by high-speed rivers in the process of opening the floodgate in floodgate upstream face bottom, can not produce the condition of serious jam or influence the floodgate body, but to a lot of drainage canals or aqueducts, the surface of water can drop a lot of suspended solids, if thick branch, some be difficult to dispersion impurity such as glass bottle, submarine also gather many stones, these surface of water impurity mix can consolidate the structural strength of silt in soft mud, silt is difficult effectively broken up by opening the floodgate in-process on the one hand, on the other hand influences very big problem and is: when the impurities with larger rigid sizes roll down into the chutes for opening and closing the sluice along with the sluice-opening water flow, when the sluice is closed, the water stop plate can be deformed and damaged in the non-designed direction, so that the sealing action of the side edge or the bottom edge of the sluice body can not be finished.
Also there are a lot of equipment to sluice bottom desilting in the existing market, generally including enclosing the fender formula, set up promptly and enclose the fender part, when silt is too much, the drive encloses fender part lifting, pile up the position with original silt and directly vacate the clearance, the second is through built-in initiative cleaning equipment at submarine, utilize the mode of suction or rotatory cleaning, directly break up silt or shift, these though can realize the silt of sluice upstream face to a certain extent and pile up the problem, but lack the influence to sluice opening and shutting in-process debris, for example, the floated huge branch of surface of water, this kind of condition is opened the floodgate, built-in submarine cleaning component can't effectively clear up, when the sluice bottom is opened, the surface of water rivers sink rapidly and take the floater to flow towards the opening, the jumbo size floater is very easily blocked in the recess of stagnant water board when passing through the bottom opening this moment, for example again, the initial stage of opening the floodgate, the high-speed rivers can blow off the soft mud of sluice surface of sluice rapidly, and then drive a lot of beginning to roll, in case there is not had the stagnant water board to pile up the jumbo size damage in case many sluice boards and to the damage.
Therefore, although some existing dredging devices can carry out independent dredging operation, influence of large-size impurities on the water surface or the water bottom on the water stop plate groove can not be effectively prevented according to the opening and closing state of the sluice, long-term stable operation of some electric control equipment built in the water is difficult to achieve, the electric control equipment does not conform to the application scene of a practical large-scale small-scale water channel sluice, and the electric control equipment cannot be popularized and applied.
