The specific embodiment
Below be example with the dredging system of sewage pipeline with large-pipe diameter that uses this small dredger, describe the concrete structure and the working method of this small dredger in detail:
Referring to Fig. 1, Fig. 2 and Fig. 3, this small dredger is as a part of dredging system of sewage pipeline with large-pipe diameter, and it is with small dredger ground operating system, inflating rubber gate and inflating rubber gate ground aerating and exhaust device cooperating.
1, small dredger, in conjunction with Fig. 4 A, Fig. 4 B and Fig. 4 C of Fig. 1, Fig. 4: it is formed by connecting by four angle cleats 4 by two buoyancy tanks 3, and four angle cleats are fixed on the buoyancy tank support of two buoyancy tanks.High speed waterproof machine 1, agitating auger oar 2 and four cameras 6 are housed on the small dredger.
Be arranged in desilting pipeline 17 during the work of down-hole small dredger, screw rotate under the drive of motor when stirring and mud to be stirred the while motive force that canoe is walked forward also is provided.Screw should have certain rigidity and flexibility simultaneously, is unlikely to damage to enough motive forces of current with when running into hard material when the rotary work to guarantee screw; Screw and should be antiwind influence operation to prevent to be wound when the work thing to twine.The camera that install in four corners of canoe is in order to observe the situation in the sewage conduct so that operating position and the direction of adjusting canoe for the ground staff provide foundation.
2, small dredger operating system on the ground, in conjunction with Fig. 4 A, Fig. 4 B and Fig. 4 C of Fig. 1, Fig. 2, Fig. 4: it shows that by a scalable guide rod 12, pulley 9, guide rod supports 16, two hawsers 7, winch 15, control cabinet 13, camera control flow 14 etc. forms.
Be two hawsers 7 on two buoyancy tanks of small dredger, two one on hawsers tie up on the ground winch 15, on the small dredger that ties up in the sewage conduct, respectively by being installed in four pulleys 9 of guide rod 12, this head at the small dredger buoyancy tank is established a hawser integrator 8, hawser 7 passes hawser integrator 8, and the staff operates winch 15 and regulates canoe in ducted operating position and direction by regulating hawser 7.Hawser integrator 8 can be two 30 ° elbow and is welded, and hawser was unlikely to rock too severe and influence the staff and operates when it made canoe work.Winch 15 and camera show that control flow 14 is placed on the ground from inspection shaft 1m distant place.The camera that camera 6 connects ground by holding wire shows control flow 14 or the camera demonstration control flow communication by wireless mode and ground.
3, inflating rubber gate and inflating rubber gate ground aerating and exhaust device:
Referring to Fig. 6 A, Fig. 6 B and Fig. 6 C of Fig. 1, Fig. 3, Fig. 6, the inflating rubber gate comprises cylindrical inflating rubber leather bag 25 and detent mechanism, puts into the operating position by desilting pipeline section downstream inspection shaft 28.Be arranged in by the downstream line 29 of desilting pipeline during the work of inflating rubber gate, aerating and exhaust device 18 charges and discharge gas by air hose 19 to the inflating rubber gate on the ground.Play after the inflating rubber gate inflation and block the water effect and make by the ducted water level of desilting and rise so that the small dredger operation.
The big I of cylindrical inflating rubber leather bag 25 is flexible within the specific limits according to the difference of its place duct size, works to be applicable in the pipeline of different-diameter.External diameter size after the inflating rubber leather bag inflation with equated by the internal diameter of desilting pipeline section downstream line 29.Inflating rubber leather bag 25 center opened round holes 26, the aperture of hole 26 is 0.6～0.8 times of inflating rubber leather bag external diameter, capping when flow is big, flow hour take off limit.Like this, thus the inflating rubber leather bag when blocking water, make its have certain discharge capacity guaranteed by the water level in the desilting pipeline section be unlikely at certain proper height too high influence small dredger work or the upstream pipeline section produced pour in down a chimney phenomenon.
One side of inflating rubber leather bag 25 is equipped with four retractable supports skeleton short tubes 24, and they play the effect that rubber gate skeleton supports.Retractable supports skeleton short tube 24 will be longer than the diameter of inflating rubber leather bag 25 all the time, retractable supports skeleton short tube that part ofly just is stuck on the mouth of pipe than rubbery human body is additional after the inflating rubber leather bag is full of gas like this, thereby has prevented that the rubber gate from being washed away by current.Wherein two of retractable supports skeleton short tube 24 in the vertical directions more much longer and transversely two look few.Retractable supports skeleton short tube is flexible voluntarily according to the size of rubbery human body.
Scalable gate control lever 20 in order to transfer and when mentioning the inflation of rubber gate and gate the staff stop gate to be flushed away by holding control lever.Scalable gate control lever 20 is formed by connecting by some short steel pipes, and the retractable supports skeleton short tube 24 on control lever and the inflating rubber leather bag is connected four-way 23 and connects by 90 ° of connecting bends 21, card ball joint 22, a steel.Because of having adopted card ball joint 22 just to make the relative position of gate control lever 20 and inflating rubber leather bag 25 to change within the specific limits, increased flexibility.Gate without the time control lever can disassemble from gate, made things convenient for the transportation of control lever and gate and deposited.
Inflating rubber leather bag 25 should be done thickening in the side that retractable supports skeleton short tube 24 is arranged and handle, to prevent water stream impulse force and the transverse pressure destruction to rubbery human body.Inflating rubber leather bag 25 charges and discharge device 18 by air hose 19 and ground air and is connected, and air charges and discharge device and can be air compressor machine.
In the said system, the miscellaneous equipment that is used with this small dredger is not limited to above form, and other similar version can also be arranged.
The course of work of above-mentioned desilting system is as follows:
The first step: be put in the pipeline for the treatment of desilting pipeline section downstream by the rubber gate of gate control lever with unaerated, charge and discharge device to rubber gate inflation by the ground air then, ground staff holds the gate control lever and is washed away by current with the rubber gate that prevents underfill gas in the process.
Second step: treat after the ducted water level of desilting rises to certain altitude small dredger to be put in the sewage pipe from the inspection shaft for the treatment of desilting pipeline section upstream, the good guide rod of frame has been managed hawser.
The 3rd step: start the high speed waterproof machine on the small dredger, the agitating auger oar begins operation and will manage the mud at the end and stir under the drive of motor, camera in the course of work on the small dredger passes to ground camera with the situation in the sewage pipe of taking and shows control flow, on the ground the staff shows that by observing control flow operates winch, by the hawser constantly position and the direction of small dredger in the adjustable pipe as required.
The 4th step: after a work pipeline section is finished and stirred operation, close motor, small dredger is proposed from pipeline and the air in the inflating rubber gate is bled off taking-up rubber gate rapidly.The sewage of accumulating in by the desilting pipeline just flows away rapidly before, and the mud that is stirred simultaneously washes away with current.The dredging operation of a work pipeline section is finished, and changes next work pipeline section over to.
