The leading section of this traction core 28 and rearward end penetrate at the through hole 29a of the fixed support (accepting parts) 29 of guide rail 12 outstanding configurations and can be supported with moving axially.By at the front and back end of traction core 28 equipment retainer 30 and by making this retainer 30 lean fixed support 29, make traction core 28 advance, bear respectively when retreating tractive force.The retainer 30 of front side is set to the fixed support 29 more forward sides than the front side, and the retainer 30 of rear side is set to more lean on rear side than the fixed support 29 of rear side.
Through hole 29a is formed by the slotted hole that extends up and down or free size hole etc., moves up and down to allow traction core 28.In addition, when shown in Figure 4 scraping collects, the left side (front side) of traction core 28 is pulled and the retainer 30 of front side is contacted with the fixed support 29 of front side, on the other hand, compression can occur in the right side (rear side) of traction core 28 when retainer 30 contacts with fixed support 29, therefore, in order to prevent this situation, the right side of drawing core 28 is moved freely to the right so that draw core 28 buckling does not occur.Therefore, as Fig. 4 right side represents with e, between fixed support 29 and retainer 30, be provided with mobile space (play).Be the dotted line state of Fig. 4 at piston 27, namely non-when scraping collection (retreating) beginning, the retainer 30 of rear side contacts with the fixed support 29 of rear side, and the left side of drawing core 28 becomes free state.Thus, traction core 28 always only acts on simple tractive force, therefore can not act on buckling.In addition, although each retainer 30 is anchored on traction core 28, can regulate the mobile appropriate gap e that just can access so long as constitute.Fixed support 29 only like that just consists of independently invention with the described structure of retainer 30.Therefore, as shown in Figure 6, the described structure of fixed support 29 and retainer 30 also goes for not possessing the driving cylinder 15 of handling part 17.
As shown in Figures 1 and 2, the end on the fore-and-aft direction of body 18 and pars intermedia in the both sides of body 18, have respectively erecting bed 33 integratedly.Three groups of wheels 34 that travel before and after being equipped with via these erecting beds 33 can rotate at guide rail 12 to constitute.In addition, also can omit guide rail 12 and the wheel 34 that travels is directly rotated at diapire 4.Other position at erecting bed 33 is fixed with pair of right and left bearing 35, and the scraper shaft 36 interting freely via these bearing 35 rotations is equipped with mud scraper plate 37.
These mud scraper plate 37 front and back are provided with three, and the interval before and after it is set to L, and changeablely become freely vertical shown in the solid line and scrape low non-collection (retreating) posture of scraping behind the front height shown in collection (advancing) posture and the dotted line.Described interval L sets shortly than the stroke S of piston 27 and cylinder body 16.These three mud scraper plates 37 constitute and utilize trace shown in Figure 2 38 and interlock connecting rod 39 interlocks.Mud scraper plate 37 and trace 38 can be integratedly around scraper shaft 36 rotations.
The 40th, front retainer (one of posture switching mechanism), when the mud scraper plate 37 of front end advanced and becomes final stage, front retainer 40 contacted with trace 38, lifts mud scraper plate 37 to switch to the non-collection posture of scraping of level.The 41st, rear retainer (one of posture switching mechanism), when the mud scraper plate 37 of rear end retreated and becomes final stage, rear retainer 41 contacted and acts on trace 38, made mud scraper plate 37 turn back to the vertical collection posture of scraping.At described trace 38 or interlock connecting rod 39, can be balancer or spring as the assembling of one of posture switching mechanism, described balancer or spring be used for making to scrape the collection posture and non-scrape the action that the collection posture switches and switch after each posture keep stable.
In addition, in extremely shown in Figure 4 the scraping under the collection posture of Fig. 1, the mud scraper plate 37 of this sludge scraping acquisition means becomes vertically, if from this state to front side water guide mouth 20 injected waters, cylinder body 16 and handling part 17 will move forward, if arrive near stroke S, will mud scraper plate 37 be lifted by front retainer 40, switch to the non-collection posture of scraping.If the position of scraper shaft 36 during the state of collection posture scraped of the solid line of Fig. 2 is made as A, B, C, the position of the scraper shaft 36 when dotted line non-scraped the state of collection posture just becomes A1, B1, C1.So the scraper shaft 36 (A1) of front end is come on the sludge sump 5, utilizes mud scraper plate 37 that sludge scraping is fallen sludge sump 5.On the other hand, the twoth scraper shaft 36 (B1) and the 3rd scraper shaft 36 (C1) are come respectively the place ahead of scraper shaft 36 (A) and the twoth scraper shaft 36 (B) of front end, the sludge scraping collection thereunto.That is, this mud of scraping collection is forwards scraped collection at the mud scraper plate 37 that follow-up phase is restored to Fig. 2.This also as disclosed in TOHKEMY 2006-205147 communique and the TOHKEMY 2005-131627 communique, also can scrape collection to the mud at rear to effective mode aspect the sludge sump 5 even be for short stroke S conscientiously.Need to prove that long S is set to slightly longer than long L.
Represent with arrow X in Fig. 2 that to scrape collection posture state and the direction of advancing mud scraper plate 37 lifts and collects state and the direction that posture retreats and represent with arrow Y with non-scraping in Fig. 2.After described mud scraper plate 37 lifts, if from rear side water guide mouth 21 injected waters, cylinder body 16 and handling part 17 will move to the right, if trace 38 retreats end forwards rotation with rear retainer 41 butts at it, mud scraper plate 27 will switch to the vertical collection posture of scraping.
In the forward both sides of cylinder body 16, erect and be provided with pillar pallet 44.Erect the pillar 45 that arranges at this pillar pallet 44 and be projected into the water surface more than 7, in the top, the crossbearer material 46 of control shown in Figure 3 is installed.Be equipped with nozzle 47 at this crossbearer material 46, spray with certain moment (when crossbearer material 46 during to Fig. 2 right-hand mobile) and carry out thereby be used in the water of carrying dregs.Certainly, also can carry out at whole reciprocating stroke from the water injection of nozzle 47.
Be provided with the transfer valve 48 of Fig. 3 in an end of crossbearer material 45, set up changer lever 49 with roller in the one side.This changer lever 49 is the parts that can keep the mode of the first switching position and these two positions of the second switching position.The contact chip 50 relative with this changer lever 49 arranges from the face of sidewall 2 is outstanding.As shown in Figure 1 and Figure 2, two places before and after contact chip 50 is provided with.
The 51st, fluid is given row controlling organization.In this controlling organization 51, the 52nd, filter, the 53rd, with the water pump of control device, they constitute: will arrange interior sewage or the water purification that flows or store in water treatment and pump up and be transported to follow-up flexible flow pipe 54, and described sewage or water purification are passed through in the pipe arrangement fixture 55 with the confession water to described transfer valve 48.In addition, dregs are removed device 8 and by actuating arm 59 the dregs that swim on the water surface 7 are depressed to suck in weir 60 via chain 58 etc. by alone driving mechanisms such as electronic or hydraulic cylinder 57.Therefore, constitute the operation that manual arm 61 is carried out and to be independent of driving mechanism 57 sides and to carry out, but also can constitute weir 60 is descended because of the interlock that approaches of described pillar 45 sides, and utilize the buoyancy on weir 60 to recover freely.
The STA representation of Fig. 1 to Fig. 4 is scraped collection (retreating) recovering state and is switched to the moment of scraping collection (advancing) state from non-.Changer lever 49 contacts and transfer valve 48 is switched to the straight circuit of Fig. 3 as shown in Figure 2 with the contact chip 50 of rear side.Thereupon, by pass in the pillar in the pillar 45 (also can be outer for pillar) pipe arrangement 63 as arrow A to front side water guide mouth 20 water fillings, and as arrow a from 21 drainings of rear side water guide mouth and turn back to supply source.By this water filling, body 18 advances to the arrow directions X of Fig. 2.If trace ahead 38 contacts with front retainer 40, the non-collection posture of scraping of mud scraper plate 37 switching levels then.Meanwhile, on the water surface, changer lever 49 contacts and is switched with the contact chip 50 of front side.Thus, transfer valve 48 switches to the oblique circuits of Fig. 3.So, rear side water guide mouth 21 water fillings as arrow b in Fig. 4, and as arrow b, make inner water discharge and return from front side water guide mouth 20.This water that returns is used as carrying dregs as the b of Fig. 4.Under the state that mud scraper plate 37 lifts, cylinder body 16 and handling part 17 retreat, and make last trace 38 with rear retainer 41 butts and switch to forward, scrape the collection posture thereby become.Although the water from nozzle 47 sprays the water that returns that utilizes Fig. 4, directly sprays from water pump 53 by transfer valve 48.
Although the handling part 17 of front and back has the function that prevents from drawing core 28 bendings, as mentioned above, the slip at sealing gasket 24 positions is the reason of wearing and tearing, thereby not preferred.Its reason is that the inflow of outside mud and sewage is caused, in order to prevent its inflow, except utilizing the pipe arrangement different from described pipe arrangement to handling part 17 interior water fillings and cleaning the inner solution, as shown in Figure 4, can also by insert to front side water guide mouth 20 and rear side water guide mouth 21 with bypass pipe 65 water fillings of choke valve 64 and from discharge outlet 25 drainings, thereby often clean inner.By choke valve 64 is set, can suppress the flow in the handling part 17, guarantee to the flow of driving cylinder 15.
Discharge water from discharge outlet 25 is water under high pressure, therefore, if to sealing gasket 24 around the traction core 28 before suitable position spray, just can entry deterrence in accumulation mud Ga process chamber 17a.Therefore, shown in the hurdle, lower-left of Fig. 5, the situation that discharge outlet 25 has close end flanges 23 central authorities to offer.In addition, with regard to the front end shape of handling part 17, so long as not the tabular surface vertical with traction core 28, but that dotted line represents in the hurdle, lower-left of Fig. 5 is hemispherical, just can make from the mud in the place ahead to get rid of with the shape of sphere coupling, invade to process chamber 17a thereby can stop.
In addition, described guide rail 12 can by and diapire 4 between the padded coamings such as vibration-proof rubber that clamp deal with earthquake.In addition, described mud scraper plate 37 switches between vertical and horizontal, and in the past, when the every trade of going forward side by side is sailed test, can't confirm its switching state above the pond in handle assembly is arranged on the pond.So, for being confirmed, it when switching mud scraper plate 37, this information is notified above the pond, and for example also air can be ejected in the water and produce sound at the water surface.
In addition, described cylinder body 16 is generally to Zhou Jinhang honing in it, but present situation is, its honing length is limited about with 4m.And as cylinder body 16, usually need as shown in Figure 4 considerably beyond 4m, this long parts of 9m or 10m for example, in this case, can be as described like that the complete short parts of honing by being welded to connect and adding section chief's cylinder 16.In addition, in addition, as shown in Figure 5, also can engage lose heart cylinder body 16a, the 16b of shorter length L a, Lb about many 4m with flange 65, form a complete cylinder body 16 of honing.Although in this case three cylinder body 16a, 16b, 16b are coupled together, its radical is not limited to this, also can be for more than two or four.
And, as other embodiment of described traction core 28, its integral body or a part are formed: take the rod-like members that is shaped as base material as the carbon fiber (comprising carbon fiber-reinforced carbon composite) of carbon axle or other nylon fiber etc.In this situation, can implement coated with improving sliding capability etc. by effects on surface.
In addition, above-mentioned traction core 28 is solid shape parts, but as the part of flow control mechanism, traction core 28 can be constituted pipe arrangement tubulose, that water or air are used of fluid passage.In Fig. 4, make traction core 28 in the situation of pipe, connect the pipe arrangement (also can manage) 67 from transfer valve 48 in the front and back end, thereby can import water or air to piston 27 left side injection zones by the left end of traction core 28.On the other hand, can pass through the right-hand end of traction core 28 to right side injection zone importing water or the air of piston 27, and can make designs simplification.In this situation, transfer valve 48 is arranged on the precalculated position above the pond, and its switching mechanism consists of simply by the sense switch relative with the end of the forward-reverse of pillar 45 with the valve switching mechanism (solenoid etc.) of this sense switch interlock.So, form tubulose by drawing core 28, utilize the movable agencies such as feed pipe 54 and portable pillar 45 to consist of flow control mechanism, and unlike Fig. 3, utilize pillar 45, can inject, discharge fluid by fixed device and pipe arrangement fully.In this situation, as long as with the front inlet side of body 18 and retreat end and relatively be equipped with sense switch and make transfer valve 48 switch interlocks, just can inject, discharge control by convection cell.
