Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
The leakage protection device that is used for penstock lighting outlet interface of the present invention, the line of wherein drawing refers to the submersible pump power line.As shown in Figure 1, this leakage protection device comprises four parts such as cannulated sleeve 3, rubber seal 4, threading tube core 6 and stressed nut 11.
As shown in Figure 2, cannulated sleeve 3 is the cylinder type hollow tube, and the one end is welded on the submersible pump power line of penstock 1 and draws jointing.Penstock 1 are provided with penstock threading hole 2 with the relative position place of cannulated sleeve 3 welding, and the aperture of threading hole 2 is more bigger than the external diameter of the submersible pump power line of wearing, and can pass electric wire smoothly and get final product.
As Fig. 1, shown in Figure 3, rubber seal 4 is fitted in the cannulated sleeve 3 by threading tube core 6.Rubber seal 4 is a frustoconic shape, and its larger diameter end is close to penstock 1.Rubber seal 4 is provided with the Sealing threading hole 5 that supplies the submersible pump power line to draw that matches with penstock threading hole 2 from penstock 1.Sealing threading hole 5 is the clear opening perpendicular to bottom surface on the rubber seal 4.When press-fiting, should note the position of Sealing threading hole 5 corresponding with the position of penstock threading hole 2.
As Fig. 4, shown in Figure 5, threading tube core 6 outside cylindrical, its outer wall is provided with the boss 7 of a circle ring.The hypomere of threading tube core 6 inside is the round platform 8 that caves in that shape matches with rubber seal 4 shapes, and the height of the round platform 8 that caves in is less than the height of rubber seal 4, and the epimere of threading tube core 6 inside is offered concave station 9.
As Fig. 1, shown in Figure 7, threading tube core 6 is fixed on the cannulated sleeve 3 by stressed nut 11, and stressed nut 11 and cannulated sleeve 3 are by being threaded.As shown in Figure 2, the outer wall of cannulated sleeve 3 is provided with outside thread.As shown in Figure 6, the hypomere inwall of stressed nut 11 is provided with the internal thread that matches with cannulated sleeve 3 outside threads, makes cannulated sleeve 3 and stressed nut 11 realize being threaded.
As shown in Figure 1, the upper end-hole inner ring of stressed nut 11 be provided with threading tube core 6 outer walls on the ring table top 12 that matches of boss 7, fixedly the time, ring table top 12 is stuck on the boss 7, make threading tube core 6 with respect to cannulated sleeve 3 not landings of fixed-site.
Boss 7 is apart from the distance of the threading tube core 6 bottom surfaces height less than cannulated sleeve 3, and after guaranteeing that threading tube core 6 compressed into cannulated sleeve 3 fully, the bottom surface tripping power water pipe 1 of threading tube core 6 has certain safe distance, not the rupture pressure water pipe.
After threading tube core 6 was fixed on cannulated sleeve 3 by stressed nut 11, rubber seal 4 compressed with penstock mutually by threading tube core 6.For guaranteeing that rubber seal 4 can be by the stressed purpose that reaches sealing of extrusion-deformation, in the smaller diameter end of the end face of the round platform 8 that caves in and rubber seal 4 mutually after the pressing, boss 7 and cannulated sleeve 3 open ends are also should leave the space between the mouth of pipe of non-welding ends, otherwise rubber seal 4 lacks the leeway of distortion.
As shown in Figure 2, vertically offer bar shaped locating slot 13 on the mouth of pipe of the open end of cannulated sleeve 3.As Fig. 4, shown in Figure 5, boss 7 lower ends on threading tube core 6 outer walls are provided with the positioning strip 14 that matches with bar shaped locating slot 13.When threading tube core 6 hypomeres are put into cannulated sleeve 3, positioning strip 14 is engaged with locating slot 13.
The engaging that it should be noted that locating slot 13 and positioning strip 14 when locating slot 13 and positioning strip 14 are set passes position relative fixed between line hole 2 and the threading tube core wire outlet hole 10 with the build-up of pressure water pipe.For preventing that penstock from passing that dislocation causes the submersible pump power line not draw smoothly between line hole 2 and the threading tube core wire outlet hole 10, should when welded hollow sleeve 3 and penstock 1, determine the direction of locating slot 13 according to the position of positioning strip 14.Also can be when casting threading tube core 6, the position of positioning strip 14 is positioned on the medial axis or the axis of symmetry of threading tube core wire outlet hole 10 as far as possible, so that when welded hollow sleeve 3 and penstock 1, on the medial axis or the axis of symmetry with the position alignment penstock threading hole 2 of locating slot 13, can guarantee that penstock pass line hole 2 and threading tube core wire outlet hole 10 position correspondences can be drawn the submersible pump power line smoothly.
As shown in Figure 8, the extruding force f of threading tube core 6 is received in rubber seal of the present invention 4 sides, and this power is pointed to rubber seal 4 center lines perpendicular to rubber seal 4 side surfaces.Power f resolves into the power f of substantially horizontal
xPower f with vertical direction
y, power f
