As shown in Figure 5, spud pile 10 is installed in the centre bore 8 of central post 6 by bearing 11, apparatus of the present invention are installed in by spud pile 10 on the riverbed 13 in river course 12, according to the riverbed situation, select the spud pile of respective length, first apparatus of the present invention are debugged during use, be installed on the riverbed by spud pile 11, according to its position in river, regulate the tolerance of gas bag the inside, make apparatus of the present invention and riverbed keep respective distance, approximate contact riverbed; Blade I 2 and blade II 9 are under the impact of flow dynamic, the rotation of drive apparatus of the present invention, thereby band cutter 7 rotates, make riverbed silt be subject to breakage, the riverbed, bottom plays certain ratio and falls, and than falling further quickening water velocity, it is large that hydraulic impact becomes, and apparatus of the present invention rotating speed is accelerated thereupon, further damaged riverbed silt, under water flow velocity and apparatus of the present invention rotating speed were constantly accelerated, the riverbed degree of depth continued to deepen, and the damaged area in riverbed also becomes large, the damage length of river bed water flow path direction also prolongs, water and silt form density current, further wash away the riverbed, form the riverbed, further form curb, form again muddy water stream in curb, under the effect of buoyancy tank and gas bag, apparatus of the present invention move down along spud pile simultaneously, keep and the corresponding distance in riverbed, the current that riverbed silt is accelerated by flow velocity are flushed to the downstream, discharge from the sand discharge outlet, so that whole section riverbed reduces.
During apparatus of the present invention specific works, begin to install apparatus of the present invention from downstream, river course afterbody first, wash away first the riverbed, form curb, apparatus of the present invention work on, every a segment distance another apparatus of the present invention are installed in the upstream, river course again, carry out successively work, each device forms the section of washing away, a plurality of apparatus of the present invention actings in conjunction, form the relay sand surfing, many sections of washing away have been connected to a line, and silt is gone out sediment ejection opening the most at last, thereby so that riverbed, whole river course reduces, during work, silt must have outlet, in order to silt is discharged the river course.
Below by example, concrete application of the present invention is described.
Example 1, get 100 meters long of certain channels and be the place, channel is wide 0.55 meter, and is high 0.8 meter, the sclerosis channel, lay 0.3 meter of Yellow River Sand thick at the bottom of canal, silt hardens behind water soaking, and pumping irrigation station is for 0.5 meter-0.8 meter of water depth, flow velocity 0.34 meter per second, apparatus of the present invention are installed in above the silt at the bottom of the canal by spud pile, and under unhurried current impacted, blade began helical rotation, the band cutter rotates, and the silt breakage is dug down and let out.After measured, let out 50 meters-70 meters under the bed load sand, let out under the suspended load apart from farther.Along with the increasing of flow velocity, it is farther that silt is washed.In this process, apparatus of the present invention move down under the effect of buoyancy tank and gas bag voluntarily, keep and the corresponding distance in riverbed, during apparatus of the present invention work eleven minute, measure the silt dinting depth and reach 0.15-0.18 rice, 1.5 meters long, 0.5 meter wide of desilting area records silt dinting depth 0.2-0.25 rice after 20 minutes, 2.5 meters of desilting areas are long, and 0.5 meter wide.
Example 2, measure 0.68 meter of the depth of water when drawing yellow lock in the peach blossom valley, water flow velocity 1.1 meter per seconds, this device is vertical circular barreled structure, 0.46 meter of blade diameter, central post is high 0.48 meter, and 0.03 meter of the cutter length of side is vertically mounted on this device on the riverbed by spud pile, measured 2.0 meters of riverbed silt dinting depth average out to, decline area 1.4-1.5 rice after working 20 minutes.
Example 3, measure 0.8 meter of the depth of water when drawing yellow lock in the peach blossom valley, water flow velocity 1.0 meter per seconds will originally be installed on the riverbed, work and measure after one hour, riverbed silt decline width is 1.4 meters, 0.7 meter of this device upstream decline length, 0.2 meter of downstream decline length, 0.2 meter of dinting depth average out to.
The broken sand of apparatus of the present invention removes the successful that becomes silted up, and only by flow dynamic, need not other outside energy, time saving and energy saving, save cost, the present invention can use in little river course, also can be applied to the large rivers such as the Yellow River, start working from estuary first during use, silt is poured the sea, carry out the work a plurality of apparatus of the present invention co-operation toward the upstream successively, just can reduce whole riverbed, solved flooding, dyke breach problem, ensured people's life security, large river is convenient to open ship's navigation, promote the water resource utilization, promote socio-economic development.
