step three: the sensor group 145 continuously measures the speed and the real-time water pressure of the catamaran hydrofoil 100 in real time, feeds back signals to the control system, and when the ascending requirement is met, a crew sends out a signal instruction to enable the vertical column connecting piece 144 to start to be folded upwards to drive the second auxiliary hydrofoil 143 to move upwards until the second auxiliary hydrofoil 143 stops moving in place, and the first-gear ascending operation is completed;
step four: the sensor group 145 continuously measures the speed and the real-time water pressure of the catamaran hydrofoil 100 in real time, feeds back signals to the control system, and when the requirement for rising again is met, the crew sends out a signal instruction to enable the vertical column connecting piece 144 to continuously start to retract upwards, so that the first pair of hydrofoils 142 are driven to move upwards and the second pair of hydrofoils 143 move upwards synchronously until the second pair of hydrofoils stop after moving in place, and the second-gear rising operation is completed.
The control starting of the lifting assembly is divided into first and second lifting gears, when the crew starts the first lifting gear, the oil cylinder 146a, the hydraulic oil pipe 146b and the hydraulic pump station 146c of the lifting assembly start to work, the hydraulic pump station 146c drives the end of the transmission rod, the transmission rod 146d is driven to press the third-step vertical strut 144c to move downwards, and then the third-step vertical strut 144c drives the second hydrofoil 143 to move downwards; when the second gear is lowered, the oil cylinder 146a, the hydraulic oil pipe 146b and the hydraulic pump station 146c of the lifting assembly do work more than that of the first gear, the hydraulic pump station 146c drives the transmission rod 146d, the transmission rod 146d can be driven to press the third-order vertical strut 144c and the second-order vertical strut 144b to move downwards, and then the third-order vertical strut 144c drives the second secondary hydrofoil 143 and the second-order vertical strut 144b to drive the first secondary hydrofoil 142 to move downwards, so that the hydrofoil is lowered and operated. Conversely, when the crew starts to raise the first gear, the oil cylinder 146a, the hydraulic oil pipe 146b and the hydraulic pump station 146c of the lifting assembly start to work, the hydraulic pump station 146c drives the end of the transmission rod to drive the transmission rod 146d to lift the third-order vertical strut 144c to move upwards, and then the third-order vertical strut 144c drives the second hydrofoil 143 to move upwards; when the second gear is lifted, the oil cylinder 146a, the hydraulic oil pipe 146b and the hydraulic pump station 146c of the lifting assembly do work much more than that of the first gear, the hydraulic pump station 146c drives the end of the transmission rod to drive the transmission rod 146d to lift the third-order vertical strut 144c and the second-order vertical strut 144b to move upwards, and then the third-order vertical strut 144c drives the second secondary hydrofoil 143 and the second-order vertical strut 144b to drive the first secondary hydrofoil 142 to move upwards, so that the hydrofoil is lifted.
When the sea condition gradually becomes worse, the sensor group 145 on the surface of the main hydrofoil senses and outputs a signal that the water pressure or the speed is lower than a set value to the terminal of the control console of the driving area through the sensor line, a crew can directly start to control the two-gear descending of the lifting assembly, the first auxiliary hydrofoil 142 and the second auxiliary hydrofoil 143 descend rapidly under the pushing of the transmission rod 146d, and the depth of the hydrofoil is adjusted.
The first propeller 121 and the second propeller 131 can be propellers, and the sailing speed of the hydrofoil catamaran 100 can be improved by changing the rotating speed of the propellers and matching with the adjustable multi-layer hydrofoils 140. When the propellers of the first monohull vessel 120 and the second monohull vessel 130 are both operated at maximum power, the first sub-hydrofoil 142 and the second sub-hydrofoil 143 of the adjustable multi-layer hydrofoil 140 are extended and lowered to maximum simultaneously, and the first propeller 121 and the second propeller 131 cooperate with the adjustable multi-layer hydrofoil 140 to assist in propelling the hydrofoil catamaran 100, thereby improving the rapidity of the hydrofoil catamaran 100.
The adjustable multilayer hydrofoil can promote the well front portion of whole hull or hull, reduces wet area, increases the afterbody draft simultaneously, reduces navigation resistance, and the afterbody of first monomer ship and second monomer ship sets up two adjustable multilayer hydrofoils of immersion propeller cooperation, has both provided the power supply for the hydrofoil catamaran, reduces the hydrofoil catamaran navigation resistance more greatly again to the rapidity of hydrofoil catamaran has been improved more.
The main hydrofoils of the adjustable multi-layer hydrofoils are fixedly connected with the first monohull vessel and the second monohull vessel, and the adjustable multi-layer hydrofoils have better effect of reducing heave, oscillation and pitch, so that the stability and wave resistance of the hydrofoil catamaran are improved greatly.
When the ship body has large longitudinal rocking angle and heave to cause the speed change or stall of a ship propeller under severe sea conditions, the sensor group can send signals in advance, so that a crew can adjust the depth and the relative position of the adjustable multilayer hydrofoils through the controller of the control device in advance, the heave and the pitch are reduced, and the seaworthiness of the ship body can be kept more compared with a single-layer hydrofoil ship.
