Embodiment
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
In the utility model, for convenience of description, the description of the relative position relation of each parts is all that the Butut mode according to Figure of description 1 is described, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
Below in conjunction with embodiment and accompanying drawing, the utility model is further described:
As shown in Figure 1, this drags for the lance hydraulic propeller and comprises upper body and lower body 1; Be installed with lower body 1 in the lower end of upper body, crossing the liquid groove and forming liquid air chamber 2 of mutual correspondence arranged respectively in the bottom of upper body and in the top of lower body 1; Have on upper body and the inlet opening 3 of crossing liquid air chamber 2 and communicating; On lower body 1 circle distribution have at least three with the hydrojet through hole 4 of crossing 2 bottoms, liquid air chamber and communicating, it is high outside and low outside skewed that hydrojet through hole 4 is.At first spear is arranged on lower body 1 bottom, then with the utility model by under the wire rope lower going-into-well, by to inlet opening 3 filling liquids, liquid through liquid air chamber 2 from 4 ejections of hydrojet through hole; Because hydrojet through hole 4 is high outside and low outside skewed, after the liquid ejection, it is descending that the utility model is subject to reaction force acts, promotes spear and arrive fast, swimmingly the predetermined point of salvaging; Can be convenient to higher in pit shaft inner fluid viscosity or hole condition that Negative Pressure Difference is larger under use, applicability is strong; Adopt simultaneously supplementary equipment few, at the bottom of labor intensity, to salvage efficient high, practical.
Can according to actual needs, the above-mentioned lance hydraulic propeller that drags for be made further optimization and/or improvements:
As shown in Figure 1, upper body comprises upper cap 7 and reducing sleeve 5; The outside of reducing sleeve 5 is inverted cone wide at the top and narrow at the bottom; The outside thread convex platform 6 that annular is arranged in the upper end of reducing sleeve 5 is installed with upper cap 7 in reducing sleeve 5 upper ends by screw thread; Have on the top of lower body 1 with reducing sleeve 5 inner corresponding cross the liquid groove, the inside of crossing liquid groove and reducing sleeve 5 formed liquid air chamber 2; Have on upper cap 7 and the inlet opening 3 of crossing liquid air chamber 2 and communicating.Like this upper body is divided into upper cap 7 and reducing sleeve 5 and carries out disassembly, cleaning after can be easy to use, make cleaning process more convenient, easily processing; The reducing sleeve 5 that is simultaneously taper wide at the top and narrow at the bottom when G.I.H, can be difficult for being obstructed by external diameter less position excessively to the larger position of external diameter, makes under the utility model lower going-into-well process more unobstructed.
As shown in Figure 1, the inside of reducing sleeve 5 is wide at the top and narrow at the bottom stepped.Liquid entered liquid air chamber 2 by inlet opening 3 and impacted the halfpace of reducing sleeve 5 inside, thereby increased the downward impact force of the utility model.
As shown in Figure 1, the groove that is threaded of annular is arranged in the upper center of upper cap 7, be installed with hanger 8 by screw thread in the groove that is threaded, on the top of hanger 8, connecting through hole 9 is arranged; Have on the upper cap 7 in hanger 8 outsides and the inlet opening 3 of crossing liquid air chamber 2 and communicating.Can be connected with wire rope by the connecting through hole 9 on hanger 8, be convenient to the dismounting of the utility model and wire rope; Easy to use.
As shown in Figure 1, be useful on the internal thread that is connected with spear in the bottom of lower body 1 groove 10 is installed.Spear can be arranged on internal thread by screw thread and install in groove 10, is convenient to the utility model and spear dismounting.
As shown in Figure 1, the bottom in liquid air chamber 2 is concave arc shape excessively.2 bottoms, liquid air chamber excessively of concave arc shape can reduce liquid resistance, and the impulse force when making liquid from 4 ejection of hydrojet through hole is larger, increases the downward thrust of the utility model.
As shown in Figure 1, the outside thread lower convex platform 11 of annular is arranged in the lower end of reducing sleeve 5, there is connecting groove the upper end of the lower body 1 corresponding with outside thread lower convex platform 11, and outside thread lower convex platform 11 is fixedly mounted in connecting groove by screw thread.Make reducing sleeve 5 and lower body 1 easy accessibility.
Above technical characteristics has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs non-essential technical characteristics, satisfies the demand of different situations.
The using process of the utility model most preferred embodiment: at first spear is arranged on lower body 1 by screw thread; And wind wire rope on the connecting through hole 9 on hanger 8; The pipeloop interface of surface flow systemic circulatory system is received on inlet opening 3, propelling force is tested and adjusted in ground after connecting again; And then precalculated position spear and the utility model integral body are sent into well under the traction of wire rope and under driving of the present utility model in; Spear is closed the surface flow systemic circulatory system with after object successfully docks, and haulage cable is synchronizeed with the propulsion device pipeloop and furled, and completes fishing.
