Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain that this is practical
It is novel, it is not used to limit the utility model.
For the drawback for solving variable diameter trunnion and fluidic generator replacement difficulty, the utility model provides a kind of underwater ditching
Mud device is raised in machine suction, and variable diameter trunnion and fluidic generator are very convenient in the present apparatus, not only ensure that connection precision, but also substantially reduce
The difficulty of offshore construction operation, improves the efficiency of ditcher at sea construction operation.In order to further illustrate the utility model
It is as follows to be described with reference to the accompanying drawings book for structure:
Mud device, including variable diameter trunnion 10, fluidic generator 30, suction sleeve 20 and suction are raised in a kind of suction of underwater trencher
Pump.
The variable diameter trunnion includes direct current pipeline section 101 and variable diameter pipeline section 102, lower end and the variable diameter of the direct current pipeline section
The upper end of pipeline section connects, and the variable diameter pipeline section cross-sectional area is gradually increased from top to bottom, the upper end opening of the direct current pipeline section and
Equipped with trunnion upper flange 103, the lower ending opening of the variable diameter pipeline section and be equipped with trunnion lower flange 104.Trunnion upper flange passes through short
Bolt is connected and fixed with external pipe, and surface is equipped with wound form gasket on it, realize variable diameter trunnion upper end opening with
The connection of external pipe.
The suction sleeve includes outer sleeve 201 and inner sleeve 202.The inner sleeve is fixed in the outer sleeve and constitutes
The suction sleeve with middle through-hole 203 and circumferential cavity 204.The side of the outer sleeve is equipped with and communicates with the circumferential cavity
High pressure water inlet 205, the outlet of the high pressure water inlet and the suction pump, the upper end of the circumferential cavity, which has, to be surrounded on
The circumferential opening of the middle through-hole upper end opening.The upper end of the suction sleeve is equipped with sleeve upper flange 206.
The suction sleeve is set to the lower section of institute's variable diameter trunnion and aspirates the middle through-hole of sleeve and the pipe of the variable diameter trunnion
Hole coaxial line, the fluidic generator are installed in method on the trunnion lower flange of the variable diameter trunnion and the sleeve of the suction sleeve
Between orchid, the trunnion lower flange of the variable diameter trunnion and the sleeve upper flange of the suction sleeve are fixed by clamping screw.
