Title: Dredging equipment
Inventor: KUIOKA KIYOSHI
IPC: E02F3/92
Filed: 1992-08-21
Abstract: PURPOSE:To improve the workability by a method wherein inlet cutters are provided to the lower part of a vertical screw conveyor while a semicircular mud-gathering plate is provided inside the inlet cutters, and thereby resistance in forward movement is decreased. CONSTITUTION:Since a mud-gathering plate 70 is incorporated inside inlet cutters composed of excavation cutters 53 and agitation blades 54, forward movement of a dredging equipment can be made without resistance in excavated and agitated sludge even in the case where the dredging is made in hard, solidified sludge. In the case where the mud-gathering plate 70 is required to be turned round in change of the direction of advance, the turning-round can be made smoothly in the softened sludge that is less resistive. An inlet device 50 prevents alien substances intermixing in the sludge from coming into the inside by checking the same with the inlet cutters. Thereby forward movement of the equipment can be made easily during operation while the mud-gathering plate can be smoothly turned round even in the case of dredging through hard sludge, and efficiency in the dredging and operation of the equipment can be improved.

Abstract: PURPOSE:To certainly detect a fault section by providing a current detector and a central device and storing current data to detect the generation of a fault and locating the fault section. CONSTITUTION:Current data of definite time width is always stored in a memory device 120. The generation of a fault is detected by a fault detector 122 and the indication data of the generation of the fault is transmitted to a writing control circuit 124 and the circuit 124 prohibits the writing of the current data to the memory device 120 after a predetermined time. Subsequently, an analyser 126 accesses the memory device 120 to analyze the data. That is, the change quantity (change quantity 1) of current values before and during the generation of the fault at every current sensor and the absolute value (change quantity 2) of the change quantity of the current values at every current sensor during and after the generation of the fault are calculated. The section corresponding to the output layer neuron unit showing the max. output value among the output layer neuron units outputting the data of the analyzed results is located as a fault section. By utilizing current data during, before and after the generation of the fault, erroneous locating operation due to a current change easy to erroneously confirm or an instantaneously generated surge current can be prevented.
