A control system and control method for improving dredging efficiency of cutter suction dredger

Abstract

The invention relates to a control system and a control method for improving the dredging efficiency of a cutter suction dredger, which relate to the control of the dredging process of the cutter suction dredger. Parameter control to effectively improve the working efficiency of the cutter suction dredger and prevent pipe plugging accidents. A control system for improving the dredging efficiency of a cutter suction dredger consists of a suction pipe, a mud discharge pipe, a mud discharge pump, a vacuum release valve, a remote display, a pressure sensor, a flow rate sensor, a density sensor, a vacuum signal sensor and The parameter control alarm device is composed of; the dredging pipe is a middle-pass cylinder, and a dredging pump is arranged at one end of the dredging pipe, and a dredging pipe is arranged at the other end of the dredging pump; A vacuum signal sensor is used to detect the vacuum degree in the dredge pipe; a pressure sensor, a flow rate sensor and a density sensor are respectively installed on the inner wall of the mud discharge pipe.

Description

technical field [0001] The invention relates to a control system and a control method for improving the dredging efficiency of a cutter suction dredger, which relate to the control of the dredging process of the cutter suction dredger. Parameter control to effectively improve the working efficiency of the cutter suction dredger and prevent pipe plugging accidents. [0002] technical background [0003] The population living in China's coastal areas accounts for about 45% of the national population. The rapid development of the national economy has brought about a tight supply of coastal land, and dredging and reclamation projects such as the construction of coastal ports and land reclamation in China have increased year by year. Especially in areas such as coastal tidal flats and shoals, it is very difficult to build ports, but it is very beneficial for land reclamation. Improving the construction efficiency of cutter suction dredgers is a very important topic for dredging e...

Problems solved by technology

[0007] There is uncertainty in people's working attention, and it is impossible to guarantee continuous maintenance of high concentration to make the equipment work in the best efficiency zone;

[0008] ② There is also an objective gap in everyone's business capabilities, and it is impossible to realize in time whether they have deviated from the optimal efficiency zone;

[0009] ③ When the optimal construction efficiency point is deviated from, the operation behavior cannot be corrected in time

[0010] The above three reasons make it difficult for the cutter suction dredger to continue to work at the best efficiency point, and it is also the root cause of the pipe blocking accident caused by human error. Therefore, it is necessary to design a new control method and device. Improve production efficiency under the premise of ensuring safety, and prevent pipe plugging accidents
