Problems solved by technology
[0004] At present, most of the side sealing devices used by major domestic dredging companies are fixed hollow sealing rings. This sealing form is not conducive to the smooth sliding of the slider, the friction is large, the sealing performance is not good, and the sediment will flow from the The joint between the elbow and the slider is punched out, and there are many moving parts and the structure is complicated

Embodiment Construction
[0021] refer to Figure 1 ~ Figure 3 , the present invention is a butt joint sealing structure of a raking suction dredger, comprising a raking pipe 1 and a suction port joint 2 installed at one end of the raking pipe 1, and the raking pipe 1 includes a liner 11 located inside and a liner located on the liner. 11 The outer casing 12 that can slide along the liner 11 and the flange 13 located at the outer end of the suction docking part 2, the inner end of the suction docking part 2 on the rake tube 1 is provided with a wear-resistant buckle 14, 2 sets of suction docking parts On the rake tube 1, it is located between the wear-resistant buckle 14 and the flange 13. The end faces of the inner and outer ends of the suction joint 2 are respectively provided with an inner rubber airbag sealing ring 3 and an outer rubber airbag sealing ring 4. The suction joint 2 There is also an air passage 5 communicating with the inner rubber airbag sealing ring 3 and the outer rubber airbag seal...

The invention discloses a rake pipe docking sealing structure of a trailing suction dredger. The sealing structure installs an inner rubber airbag sealing ring and an outer rubber airbag sealing ring, which can be deformed by inflation, on a rake pipe and a suction port for docking Between the butt parts, the sealing performance of the butt joint position can be adjusted by controlling the inflation amount of the air bag part, so that a good sealing of the butt joint position can be achieved. The wear-resistant retaining ring and the flange plate are crimped on the seal to achieve sealing, which does not affect the movement of the casing, and can enhance the overall sealing performance of the joint. The invention is used in the field of trailing suction dredger structures.
Description
technical field [0001] The invention relates to the technical field of a trailing suction dredger, in particular to a butt joint sealing structure of a trailing suction dredger. Background technique [0002] Due to the need for dredgers to dig deep, trailing suction dredgers with a digging depth of more than 35 meters need to be equipped with underwater pumps. There are few domestic trailing suction dredgers with underwater pumps. [0003] At present, when the underwater pump is used, the side seal is not good, which leads to the pollution of the appearance of the ship, the pollution of the water around the ship, and the loading output and time are also affected. With regard to the side sealing device products, various design institutes and manufacturers currently have their own standard products, which are confidential products, but none of them have played a good role. Products designed abroad seem to be easy to use, but they are also confidential products. With the incr...
