Five, the specific embodiment: the utility model is described further below in conjunction with accompanying drawing:
Fig. 1 is the overall schematic of the utility model, and Fig. 2 is the upward view of the utility model, and Fig. 3 is the longitudinal section of the utility model; Fig. 4 is the lateral opening side expanded view of the utility model, in conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, and jetting drilling well shower nozzle; Comprise head body 1, on the head body 1 weep hole is arranged, inside has the exhalant canal of vertical arrangement to communicate with weep hole; Built-in nozzle in the exhalant canal, nozzle plays the effect into the water column supercharging.Head body 1 is the taper of flush end for front end, and front end is that flush end is in order to leave certain wall thickness for the nozzle in the head body 1, prevents the quartz sand particle polishing head body 1 that reflects to make its wearing and tearing, causes nozzle to fly out.Weep hole comprises mesopore 2 with lateral opening 3, and mesopore 2 is positioned on the flush end of head body 1 front end, and lateral opening 3 are positioned on the tapered slope of head body 1, and lateral opening 3 is that arrange radially at the center with mesopore 2.Mesopore 2 is positioned at head body 1 foremost, and it can provide the jet power of maximum in order to broken rock.Lateral opening 3 owing to be positioned on the tapered slope of head body 1, and the water column jet power that therefore provides is slightly smaller than mesopore 2.Head body 1 is the taper of flush end for front end, and this structure helps broken step by step rock, and the speed of mesopore 2 is maximum; At first broken rock; Help lateral opening 3 jets to form the pore-forming of even rule then, in addition, pyramidal structure also helps the propelling of shower nozzle and the discharge of landwaste.
The exhalant canal of mesopore 2 is consistent with the shower nozzle axis direction, and lateral opening 3 exhalant canal tangentially tilts respectively 5 ~ 15 °, and lateral opening 3 exhalant canal incline direction is consistent.The effect that lateral opening 3 exhalant canal tangentially tilts respectively mainly is to enlarge lateral opening 3 projected area; Because shower nozzle is sent to while spraying when breaking rock; Make that have lateral opening 3 of inclination angle does not stop conversion and spray site, enlarged projected area greatly, and the projected area between each weep hole reaches and partially overlaps; The spray-hole of shower nozzle ejection no longer is a single hole, but forms a big pore-forming.The setting at 5 ~ 15 ° of inclination angles will be satisfied jet and be greater than brokenly rock power at nozzle axis to decomposing force, also will make the projected area of adjacent two weep holes overlap, and angle is excessive or too small all improper.
In order to enlarge the projected area of the utility model; Lateral opening 3 exhalant canal forms 2 ° of angles at the direction and the nozzle axis line of mesopore 2 dorsad; Effect is that the water column of lateral opening 3 ejections is dispersed to the outside of head body 1, enlarges the projected area on rock, and the shower nozzle diameter is about 100mm; Can form the pore-forming of about 120 ~ 130mm apart from the injection of rock 100mm place, send to while make things convenient for the utility model when jetting, to spray.
During use, shower nozzle is connected flexible steel pipe, give by the high pressure pump truck and press, directly spray brokenly rock and get final product.Produce reverse torsional forces when preventing that the utility model from spraying; Thereby cause the junction of shower nozzle and steel pipe to produce back-off; Exhalant canal with lateral opening 3 tangentially forms clockwise inclination angle respectively, like this, can produce certain positive torque power; Make to be threaded tightlyer between shower nozzle and the steel pipe, prevent back-off.
Figure 14 is resolution of forces figure lateral opening in the utility model, and is as shown in the figure, when jetting; Because lateral opening 3 is inclined design, when the ejection water column, the power of each weep hole can be decomposed into x axle, y axle, three directions of z axle; But because head body 1 be conical, lateral opening 3 is that arrange radially at the center with mesopore 2, and lateral opening 3 exhalant canal incline direction unanimity; When a plurality of power of lateral opening 3 are carried out when comprehensive; The axial power of x axle and z is cancelled basically, this during to the shower nozzle drilling depth formed well track do not have influence basically, prevent that deviation from appearring in well track.
Fig. 5 is the overall schematic of another embodiment of the utility model; Fig. 6 is the upward view of another embodiment of the utility model; Fig. 7 is the longitudinal section of another embodiment of the utility model, and Fig. 8 is the lateral opening side expanded view of inner ring in another embodiment of the utility model, and Fig. 9 is the lateral opening side expanded view in outer ring in another embodiment of the utility model; In conjunction with Fig. 5, Fig. 6, Fig. 7, Fig. 8, shown in Figure 9; Other a kind of embodiment of the utility model is lateral opening 3 to be divided into inside and outside two circles, and the inclination angle size that the exhalant canal of lateral opening 3a of inner ring and the lateral opening 3b in outer ring tangentially forms respectively is consistent, in the opposite direction.Because the power of each weep hole can be decomposed into x axle, y axle, three directions of z axle; The inclination direction that lateral opening 3a of inner ring and the lateral opening 3b in outer ring tangentially form is opposite; Make the axial power of x axle and z by the part of cancelling out each other, when preventing the shower nozzle injection well track is impacted.The exhalant canal of the lateral opening 3a of inner ring tangentially forms counterclockwise inclination angle respectively, and the exhalant canal of the lateral opening 3b in outer ring tangentially forms clockwise inclination angle respectively.Because the number of the lateral opening 3b in outer ring is more than the number of the lateral opening 3a of inner ring; Therefore; The clockwise torsional forces that the lateral opening 3b in outer ring produces during injection will be greater than the counterclockwise torsional forces of the lateral opening 3a generation of inner ring, and after the two balanced out a part, residual value still was clockwise torsional forces; This power makes and is threaded tightlyer between shower nozzle and the steel pipe, prevents back-off.
Figure 10 is the overall schematic of single hole shower nozzle, and Figure 11 is the upward view of single hole shower nozzle, in conjunction with Figure 10, shown in Figure 11; Present existing shower nozzle is the single hole shower nozzle, promptly has only a weep hole on the shower nozzle, because jetting needs very big pressure; Promptly 45 ~ 50MPa could break rock, so the aperture of the weep hole of shower nozzle is limited; Have only about 5mm, the pore-forming aperture of spraying back formation can only reach 20 ~ 50mm.After forming pore-forming, change if certain geology takes place the earth, pore-forming is easy to take place to stop up even disappear.
Figure 12 is the overall schematic of straight hole shower nozzle, and Figure 13 is the upward view of straight hole shower nozzle, in conjunction with Figure 12, shown in Figure 13; The straight hole shower nozzle is the improvement that the single hole shower nozzle is done; Because it is less that the single hole shower nozzle sprays the aperture of back formation, can't meet the needs of production, therefore be transformed into the straight hole shower nozzle of porous.But the shortcoming of straight hole shower nozzle is; Because the water column that straight hole sprays receives the restriction of shower nozzle area perpendicular to rock face, the weep hole number is limited too; Make the straight hole shower nozzle spray the back and form single hole one by one; The projected area of single hole can not form overlapping, can't form a big pore-forming, and shower nozzle can not follow up after spraying thereupon.
