Description
Technical Field
The invention relates to the technical field of dredging equipment, in particular to a dredging device for water conservancy facilities.
Background
The water conservancy facilities generally comprise dams, drainage channels, aqueducts and the like or related equipment, the drainage channels or the aqueducts are used for agricultural irrigation, the sluice for sectionally adjusting water quantity is generally arranged in a water channel of the water channel, the opening and closing position of the sluice, particularly the upstream surface bottom for blocking the water flow direction, often accumulates sludge formed by a plurality of impurities, the sludge not only affects the normal opening and closing of the sluice, but also blocks the sluice, the sluice which is generally distributed at present is a whole plate sluice which is vertically and slidingly opened and closed, the side edge and the bottom of the sluice are corresponding to the dam body around the sluice are provided with corresponding sliding grooves, the bottom or the side edge of the sluice is generally provided with deformable water stop plates, and the water stop plates are made of rubber materials or variable metals and are used for being in butt joint with grooves at the bottom of the sluice dam body to realize sealing and water blocking functions.
The silt of general soft mud class stacks up and can be broken up by high-speed rivers at the in-process of opening a floodgate water face bottom to can not produce serious jam or influence the condition of floodgate body, but to many drainage canals or aqueducts, the surface of water can drop many suspended solid, some be difficult to disperse impurity such as thicker branch, glass bottle etc. the water bottom also gathers a lot of stones, these surface of water impurity mix and can consolidate the structural strength of silt in soft mud, on the one hand silt is difficult to be effectively broken up at the in-process of opening a floodgate, on the other hand influences very big problem: when the impurities with larger hard sizes roll down to the sliding groove of the sluice to open and close along with the sluice water flow, the water stop plate can be deformed and damaged in the non-design direction when the sluice is closed, so that the side edge or the bottom edge of the sluice body can not finish sealing action.
There are also many devices for dredging the bottom of a sluice, generally including enclosing the baffle member, namely set up and enclose the baffle member, when silt is too much, drive and enclose the baffle member to rise, with the direct vacation clearance of original silt accumulation position, the second is through the initiative cleaning device of built-in the bottom of the sluice, utilize suction or rotatory mode of cleaning, directly break up or shift silt, these can realize the silt accumulation problem of sluice upstream face to a certain extent, but lack the influence to the debris in the sluice open and shut the in-process, for example, the big branch that the surface of water floats, this kind of condition opens the sluice, the clearance member of built-in bottom of the sluice can't carry out effective clearance, when sluice bottom is opened, the surface of water rivers subside rapidly and carry the floater towards the opening flow, at this moment the large-size floater is very easy to block in the recess of stagnant water when opening through the bottom, for example, the initial stage of opening the sluice, high-speed rivers can be blown down the soft mud of sluice upstream face, and then drive a lot of stones and begin to roll, the large-size stones once do not cross the recess of the stagnant water board, pile up and will cause the injury to the sluice.
Therefore, although the existing dredging devices can perform independent dredging operation, the influence of large-size impurities on the water surface or the water bottom on the grooves of the water stop plates cannot be effectively prevented according to the opening and closing state of the sluice, long-term stable operation of some electronic control equipment built in the water is difficult, the existing dredging devices are not in line with the actual vast small-scale sluice application scenes, and cannot be popularized and applied.
