Fig. 1 is the structural representation of the embodiment of the present invention, for the ease of understanding internal structure, is drawn as transparent by telescopic machine fixed support；
Fig. 2 is the middle spout fan blades of the embodiment of the present invention and flexible dummy slider attachment structure schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention, after having read the present invention, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present invention.
Example 1
Referring to shown in Fig. 1, Fig. 2, the long-range strand controlling variable-diameter inhales ship spout, is mainly made up of remote control telescopic machine 1, telescopic machine fixed support 2, spout fan blades 3, fan-shaped flexible dummy slider 4, ring flange 5, screw hole 6 and flexible connection button 7.Remote control telescopic machine 1 uses the achievement (number of patent application 201320302251.6 of utility model patent remote control jack, license notification number CN 203269461 U), all remote control telescopic machines use unified wireless wave segment signal, use a remote controller to control all remote control telescopic machines 1 simultaneously, realize the even variation of spout, and simplify remote control process.Remote control telescopic machine 1 is welded on telescopic machine fixed support 2 upper end.Straight-tube shape telescopic machine fixed support 2 chooses stainless steel material, and telescopic machine fixed support 2 lower end is welded on ring flange 5.Multiple spout fan blades 3 were around one week, form big top and small bottom round table-like variable-diameter jet pipe, spout fan blades 3 is hollow-core construction, inside set dummy slider groove 8, connected by a piece of flexible dummy slider 4 between adjacent two spouts fan 3, i.e. flexible dummy slider 4 part is embedded in the dummy slider groove 8 of a spout fan blades 3, and another part is embedded in the dummy slider groove 8 of another spout fan blades 3；Flexible dummy slider 4 sets water proof rubber 9 with the junction of dummy slider groove 8.Flexible dummy slider 4 uses titanium alloy to make, and can realize the Flexible change of jet pipe, and density is little, can reduce the quality of spout.A piece of spout fan blades 3 upper end connects a remote control telescopic machine 1, and spout fan blades 3 lower end is flexibly connected with ring flange 5 by being flexibly connected button 7.Ring flange 5 is inhaled ship pipeline by screw hole 6 with strand with pad by screw and is connected.
During specifically used, in the case of in mud, soil property granule is relatively big, critical flow velocity is higher, if the construction too low easy generation plugging phenomenon of flow velocity.In this case, remote controller is used uniformly to reduce spout caliber to optimizing operating mode.Due to spout caliber reduce, construction flow velocity increase, increase to slightly above critical flow velocity time, flow velocity and flow velocity fluctuation relatively small, can ensure largely strand inhale ship equipment safe and stable operation.
During long-distance sand transport, often the internal row pressure of conveyance conduit is higher, if not only can threaten the safety of mud and spoil disposal pipeline higher than equipment tolerance range, also can increase equipment oil consumption, reduce production efficiency.In this case, remote controller can be used uniformly to increase spout caliber to optimizing operating mode.Owing to spout caliber increases, construction flow increases, and row pressure reduces accordingly, can save strand and inhale ship oil consumption incomparably, ensure the safety of workmen and equipment, can obtain bigger economic benefit and social benefit.
Example 2
In this second embodiment, for reducing spout cost, flexible dummy slider 4 can be used instead cold rolling thin steel.It is flexibly connected button 7 and can change built-in movable rotation-shaft into, the workload of manufacturing process can be reduced.In addition to above-mentioned structure, the structure of the second embodiment is identical with the structure of the first embodiment with reference to Fig. 1 and 2, and therefore, identical reference is used for representing the identical parts explained in the first embodiment.
