Understandably, can consider in said roller 121, counterweight 125 not to be set according to the flow condition in river; When river flow is crossed when low, in addition can in said roller 121, be provided with proportion less than 1 object to increase the buoyancy of said roller devices 12.
Alternatively, the external surface of said bored roll formula roller can be opened a little apertures, so that the water inlet of said roller, thereby the buoyancy of less said roller.
Shown in Fig. 4 a, the two ends of said roller 121 also are respectively equipped with end cap 121a, and two said end cap 121a adopt embedded design.Water (flow) direction is j; It is k that said roller 121 receives force direction, when said roller devices 12 in rolling process during run-off the straight, the suffered river impact force in the two ends of said roller 121 will change; In figure, the suffered river impact force of the A of roller 121 end is just held greater than B.Said end cap 121a has the effect of automatic straightening to the rolling of said roller 121.Add the draw of said floating body 10, the correcting action of guide strip 24, guaranteed that the direction of advance of said controllable type Hydrodynamic force automatic slit remover and the direction of current are consistent.
Particularly, be connected by flat key between said hitch frame 22 and the said roller shaft 122, thereby can not rotate.Said guide strip 24 is installed on said hitch frame 22, can reduce the possibility of run-off the straight in said roller devices 12 rolling processes.When the roller direction of said roller devices 12 and water (flow) direction were inconsistent, said guide strip 24 produced a corrective force, and maintenance is vertical as far as possible with water (flow) direction for the axis when said roller devices 12 is rolled, and makes said roller devices 12 better roll.Understandably, the position of said guide strip 24 is not limited to the centre position among the figure, also can be placed on both sides, and quantity is not limit.
Particularly, shown in Fig. 5 and Fig. 5 a, the roller shaft 122 of said roller devices 12 is offered a slotted eye 122a, and the electromagnetic clutch 124 in said cable 20 passes said slotted eye 122a and is installed on said roller is connected.Understandably, said slotted eye 122a can replace with groove milling, after said cable 20 passes said slotted eye 122a or groove milling, needs further to adopt adhesives such as epoxy resin or glass cement its slit to be blocked and fixing dead said cable 20.
Clutch closed, that separate when switching on when preferably, said electromagnetic clutch 124 is recommended to use outage.That is, during power-failure close, said roller 121 and roller shaft 122 " locking ", said roller devices 12 stop to roll; When energising separated, said roller devices 12 rolled forward.Because said roller devices 12 works under water, therefore when the said roller devices 12 of design, should consider to insulate, withstand voltage and silt is to the problems such as influence of said electromagnetic clutch 124 foldings.
Alternatively; Shown in Fig. 7 and Fig. 7 a, in another embodiment of the present invention, said roller 121 can also be designed to the spiral structure of winning in succession; Said roller 121 comprises end plate 121b, 121c and fixed head 121d win in succession; Two said end plate 121b are installed on the two ends of said roller 121, and the said fixed head 121d of polylith is installed on the external surface of said roller 121, and the said 121c of winning in succession of polylith is installed on the said fixed head 121d.Adopt such design, good manufacturability, handling ease, convenient disassembly, space shared during transportation is less, and can said electromagnetic clutch 124, counterweight 125 be installed on the centre of said roller 121.
Please refer to 8 with Fig. 8 a; The operating principle of present embodiment controllable type Hydrodynamic force automatic slit remover is following: said roller devices 12 is drawn and is sunken in water-bed 101 by said floating body 10 through said pull rope 18, and the blade 123 of said roller devices 12 inserts in the silts 102.When the roller 121 of said roller devices 12 rolls down (rotating direction is shown in arrow J among the figure) in the promotion (water (flow) direction is shown in arrow N among the figure) of current and the traction of said floating body 10, said blade 123 will be deposited on the bottom in the rolling process of said roller 121 silt 102 starts with washed away.In addition; The barrier effect of roller 121 can be accelerated the flow velocity of river between roller 121 and the bottom, riverbed; And because the support of blade 123 is arranged, said roller 121 has a gap in rolling process and between the riverbed, current during through this gap that becomes narrow flow velocity can accelerate; And at the effect of the blade 123 water generates spiral of going to river, this has strengthened the erosion of river to the riverbed widely.
When making said roller shaft 122 through the electromagnetic clutch 124 in the said roller 121 with said roller 121 " locking ", can not rotate between promptly said roller 121 and the roller shaft 122, just formed on-position as shown in Figure 8.Because hitch frame 22 and roller shaft 122 link together through flat key, also can not rotate between them.Therefore; Hitch frame 22 is under the huge moment of torsion of roller devices 12; With roller 122 rotations, might cause the front end of hitch frame 22 to insert in the silt 102, or turn round in an angle with pull rope 18; Whole like this roller devices 12 just can not roll and advance, and has promptly realized stopping of said roller devices 12.Even because pull rope 18 tension make the front end of said hitch frame 22 not insert in the silt 102; Because said roller devices 12 own wts make said blade 123 insert deeply in the silt 102, huge frictional force also can brake wheel device 12.
Under on-position as shown in the figure; Because the supporting role of said blade 123; Said roller 121 keeps a gap with the bottom, riverbed all the time; And the current through this gap and will be rolled the silt of river bed rapidly because the barrier effect of said roller 121 and blade 123 will become rapid, agitate, circles round.And stop the roller devices 12 that roller advances because following silt is swept away, will sink, and in the sinking process, said roller 121 also can keep certain interval all the time with the river bed.Rapid river can wash away the riverbed of the said roller devices of erosion 12 bottoms all the time.In theory, this process will go on always, and is concordant with the river bed up to the top edge of said roller devices 12.In a short period of time, will form a hole below the said roller devices 12.The time of staying is long more, cheats dark more.If make said roller devices 12 angle of rolling forward this moment under said programmable logic controller 162 predefined programmed instruction, between 1/3 thoughtful 1 week, said roller devices 12 small distance that will advance.Under said programmable logic controller 162 predefined programmed instruction, make 124 pairs of said roller devices 12 of said electromagnetic clutch brake once more then.Said roller devices 12 stays for some time, and can below it, form a new hole again, so circulation, and the vestige that said roller devices 12 rolls across will be pulled out a zanjon in the river bed.
Preferably, said blade 123 not only plays a supportive role, and it also provides the motive force of advancing for advancing of said roller 121, can also change the direction of a stream of water.As shown in the figure, because the barrier effect of said blade 123, it is mobile to make that a part is just becoming along the K direction along the mobile river of M direction, goes to impact the river bed.
Secondly; With fine sand is that sedimental riverbed is at the bottom of can forming unique semilune ripple glaze under the washing away of river; The same with the semilune sand dune in the desert, such shape meets fluid mechanics principle, is the most erosion resistant shape; When roller 121 rolls across, destroyed this shape, also can strengthen the erosion of river the riverbed.And, utilize controllable type Hydrodynamic force automatic slit remover of the present invention to clear up repeatedly, can be drawn out a narrow zanjon at the center in river, this narrow bottom of trench river flow velocity also will increase, and natural erosion effect also will strengthen.Under the natural erosion of river, this narrow zanjon of being pulled out by dredger can constantly be widened under the normal erosion of river like this.Because under the same flow, the water channel of river narrows down, and the flow velocity of river will be accelerated.When river was lower than certain critical flow velocity, the silt in the river will deposit, and when being higher than this critical flow velocity, and silt can be flushed away with regard to deposition no longer.The flow velocity of river can be faster after the river course narrowed down, and the river that flow velocity is accelerated will be accelerated the natural erosion effect to the riverbed.The speed and the effect of the desilting in river course have so also just been accelerated widely.
Controllable type Hydrodynamic force automatic slit remover of the present invention can not cause damage to riverbank and dykes and dams.Since the effect of self gravitation, said controllable type Hydrodynamic force automatic slit remover can walk automatically river the most deeply, the most rapid centre position.Through racing crook, river the time, because the effect of said pull rope 18, the movement locus of said roller devices 12 can be partial to the inboard a bit, and dykes and dams in the outer part not.
It should be noted that because electric supply installation 14 and control device 16 are installed on the said floating body 10, therefore in design and manufacture process, will consider measures such as " anti-rolling ", " anti-water inlet ".In addition, can be provided with literal, sound, radio signal, warning lamp etc. on the said floating body 10, to remind passing ships and to guarantee the safety of passing ships.In the present invention, the effect of said floating body 10 is following: (1) play the guiding role, and makes the roller 121 of said roller devices 12 in rolling process, be unlikely to tilt; (2) tractive force of increase pair roller 121; Also in the speed of rolling, rolling how or the like whether (3) play marked effect, roller 121 is judged probably where in the position that people can be through floating body 10; (4) electric supply installation 14 and control device 16 electric equipments such as grade are installed.
