Detailed Description
In order to make the present invention more easily and clearly understood, the technical solutions and technical effects of the present invention will be described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1 to 3, the marine riser brush for deep water of the invention comprises a short drill pipe 1, wherein an upper guide block 2, a stop ring 3, a brush sleeve mandrel 6, a bailing cup centering rib 7, a bailing cup 8 and a lower guide block 9 are sequentially arranged outside the short drill pipe 1 from top to bottom. Go up guide block 2 and weld inside keeping off 3 upper ends of ring, evenly be provided with six along keeping off 3 inside circumferences of ring, keep off 3 lower extremes of ring and be connected with brush cover dabber 6 through the external screw thread, brush cover dabber 6 outside is provided with brush cover 5. The baffle ring 3, the brush sleeve mandrel 6 and the brush sleeve 5 are fixedly connected together through a fixing pin 4.
