Freeman and Thomas L. Murphy, Idaho Falls, Idaho, assignors to the United States of America as represented by the United States Atomic Energy Commission Filed Apr. 26, 1966, Ser. No. 546,143 6 Claims. (Cl. 239-186) The invention described herein was made in the course of or under a contract with the United States Atomic Energy Commission.
This invention relates to an apparatus for applying fluid to the interior of an object. More specifically, the invention relates to a device that can be readily inserted in a top opening of a vessel for spraying a large part of the interior of the vessel.
In the drawings:
FIG. 1 is an elevational view of the novel apparatus of the present invention;
FIG. 2 is a fragmentary sectional view of the upper part of the apparatus;
FIG. 3 is a fragmentary view, partly in section, of an intermediate portion of the apparatus;
FIG. 4 is a sectional view taken on the line 44 of FIG. 3; and
FIG. 5 is a sectional view taken on the line 55 of FIG. 3.
As shown in FIG. 1, the novel apparatus of the present invention comprises essentially a rotatable vertical shaft and a gun 11 mounted on the shaft for vertical movement therealong in response to rotation of the shaft. Thus the gun 11 moves in a spiral path and is adapted to spray paint, dye, or water over an extensive area of the interior of a vessel (not shown) such as a pressure vessel for a nuclear reactor. The present apparatus will be applied to the vessel by insertion of the shaft 10 and gun 11 through an opening in the top of the vessel.
As shown in FIGS. 2 and 3, the shaft 10 has an upper part 12 which is circular in section, extends through a housing 13, and is journaled therein on two closely spaced ball bearings 14 at the upper end of the shaft part 12 and on a roller bearing 15 at the lower portion of the shaft part 12. The shaft 10 is rotated by a pinion 16 Which is keyed to the upper end of the shaft part 12 between the bearings 14.
As shown in FIG. 1, power to drive the pinion 16 comes from an electric motor 17 which is mounted on the housing 13. The motor 17 is connected with a speed-reducing drive 18, which, as shown in FIG. 2, includes a gear 19 meshing with the pinion 16.
As shown in FIG. 2, the upper end of the upper shaft part 12 is connected by means of a swivel 19a to an elbow 20, which is in turn connected to a line 21 through which air or a washing liquid such as water is supplied. The swivel 19a is so constructed that one part thereof connected to the elbow 20 does not rotate and another part thereof connected to the upper shaft part 12 does rotate. The upper part 12 of the shaft 10 has an axial passage 22 which extends from the upper end of the part 12 in communication with the swivel 19a, elbow 20, and line 21 downward to a region that, as shown in FIG. 4, is near the lower end of the housing 13. At this region the axial passage 22 is connected through a short transverse passage 23 with a longitudinal passage 24, which is offset from the axis of the shaft 10 so as to clear a cross shaft 25 which extends through and across the upper shaft portion 12 and is rotatably mounted therein. The purpose of the shaft 25 will be described presently. The upper shaft portion 12 has a side outlet 26 leading to the longitudinal passage 24. A coiled tube 27 is connected at one end with the side outlet 26 and at the other end, as shown in FIGS. 1 and 3, with the gun 11. Because the tube 27 is coiled, it connects the side outlet 26 with the gun 11 at all times, regardless of movement of gun 11 along the shaft 10.
The gun 11 is attached to a carriage 28 which surrounds a lower part 29 of the shaft 10. As shown in FIG. 5, the lower shaft part 29 is hollow and rectangular in section and is engaged on four sides by rollers 30 mounted in the carriage 28. By virtue of this arrangement, the carriage 28 and gun 11 may move vertically along the lower shaft portion 29 without rotating with respect thereto. The lower shaft part 2.9 is secured by screws 31 to a rectangular lower extension 32 on the upper shaft part 12 so as to rotate therewith.
As shown in FIG. 3, the upper shaft portion 12 has opposed lateral projections 33 through which the cross shaft 25 extends. Thus the support of the cross shaft 25 in the upper shaft part 12 is increased. One end of the cross shaft 25 is fixed to a bevel gear 34 meshing with a fixed crown gear 35 attached to the lower end of the housing 13. The other end of the cross shaft 25 is fixed to a spur gear 36 meshing with a spur gear 37. The spur gear 37 is secured to a shaft 38- which extends transversely to the upper shaft portion 12 and is rotatably mounted thereon. A sprocket 39 is secured to the shaft 38 and meshes with the interior of the upper end of a sprocket-chain loop 40. As shown in FIG. 1, the interior of the lower end of the sprocket-chain loop 40 is engaged by an idler sprocket 41 carried on an idler shaft 42 mounted at the lower end of the lower shaft portion 29. A base member 42a for the shaft 10 is secured to and within the lower end of the lower shaft portion 29. As shown in FIGS. 3 and 5, a bracket 43 attached to the carriage 28 is secured to one side of the sprocket-chain loop 40 by a channel 44 and bolts 45. The bracket 43 and channel 44 clamp the one side of the sprocket-chain loop 40 between them, and the bolts 45 pass through the bracket, the channel, and the one side of the sprocket-chain loop.
Referring to FIG. 3, when the shaft 10 is rotated with respect to the housing 13 and the fixed crown gear 35, the bevel gear 34 revolves in mesh therewith about the axis of the shaft 10 and so is made to rotate about the axis of the cross shaft 25. This shaft, being fixed to the bevel gear and to the spur gear 36, rotates and causes the gear 36 to rotate. This rotation is transmitted to the spur gear, shaft 38, and sprocket 39, and movement of the chain loop 40 results. Since the carriage 28 is attached to the chain loop 40 by the bracket 43, channel 44, and
bolts 45, the gun 11 moves with the chain loop 40, that is, vertically along the lower shaft portion 29. Since the lower shaft portion is rectangular in section and is engaged on all sides by the rollers 30 of the carriage 28 for the gun 11, the gun rotates with the shaft 10, but not with respect thereto. Thus, in summary, the shaft 10 and the gun 11 rotate jointly, and at the same time the movement of the sprocket-chain loop 40 due to rotation of the shaft 10 causes the gun 11 to move along the lower shaft portion 29. These rotary and longitudinal movements of the gun 11 are combined into a spiral movement, which enables the gun to deliver liquid over an extensive area of the interior of a vessel.
In operation, the apparatus of the present invention is lowered by means (not shown) into a vessel to be treated so as to have the base member 42a rest on the base of the vessel and the axis of the shaft 10 to be on the axis of the vessel. The top of the vessel will be somewhat below the motor 17. In succession the apparatus may apply dye, wash, and developer to the interior of the vessel in order to test whether the lining of the vessel may be penetrated and thus to indicate how successfully the vessel will be at keeping radioactive matter from escaping'For application of dye, air is delivered to the gun 11 through the line 21, elbow 20, swivel 19a, passages 22, 23, and 24, outlet 26, and coiled tube 27 to the gun 11, from which dye is sprayed. For application of wash, a by-pass valve (not shown) above the spray gun 11 causes water supplied by the line 21 to be delivered independently of the spray gun. For application of developer air is again supplied by the line 21 to the present apparatus and causes developer to be delivered by the gun 11.
It is also understood that the invention is not to be limited by the details given herein but that it may be modified within the scope of the appended claims.
