Problems solved by technology

[0002] For cutter suction dredgers, the construction parameters are closely related to the soil quality, and the optimization of construction parameters is closely related to the energy consumption and output of the dredger. In engineering practice, the selection and adjustment of dredging parameters often depend on the operator's on-site Based on experience, there is no experience and basis for the operation parameters of specific soil quality, and the use of professional large-scale construction simulation devices or the use of real ship tests is expensive, time-consuming, and energy-consuming
Moreover, in terms of scientific research, the observation of the movement law of underwater mud particles and the shape of the flow field is complicated, and computer simulation is often used, and its accuracy needs to be verified by experiments.

Abstract

The invention relates to a small construction simulating device for a cutter-suction type dredger. The small construction simulating device comprises electric control equipment, a rail and a transparent wear-resistant water tank. A movable rack is arranged on the rail, and the movable rack is provided with wheels, mobile motors, locking mechanisms, a transverse motor, a lead screw, a dredge pump and a dredge pump motor. The lead screw is matched with a sliding table which is provided with a rotary motor, a telescoping mechanism and a swing arm, and the rotary motor is connected with a transmission shaft through a universal joint. The transmission shaft is provided with a 3D print rimer which is located in the water tank, the telescoping end of the telescoping mechanism is hinged to the swing arm, a pressure sensor which is connected with the 3D print rimer is arranged on the portion, at an inlet of the dredge pump, of a mud conveying pipe, and a pressure sensor and a productivity meter are arranged on the portion, at an outlet of the dredge pump, of the mud conveying pipe. By means of the electric control equipment, construction operation can be simulated in a manual single-step mode and in a full-automatic mode. By means of the device, the functions of propulsion and positioning, transverse moving, swing lifting, rotational cutting and mud discharge of the cutter-suction type dredger can be simulated quickly at low cost, and underwater flow field observation is achieved.

Description

technical field [0001] The invention belongs to the field of cutter suction dredging, in particular to a small construction simulation device for a cutter suction dredger. Background technique [0002] For cutter suction dredgers, the construction parameters are closely related to the soil quality, and the optimization of construction parameters is closely related to the energy consumption and output of the dredger. In engineering practice, the selection and adjustment of dredging parameters often depend on the operator's on-site It is carried out empirically, and there is a lack of experience and basis for the operating parameters of specific soil properties, and the use of professional large-scale construction simulators or real ship tests is expensive, time-consuming, and energy-consuming. Moreover, in terms of scientific research, the movement rules of underwater mud particles and the observation of flow field morphology are complex, and computer simulation is often used...
