Fourthly, manganese nodule collection:
and (3) the staff on the control ship makes the collection ship slowly advance, simultaneously starts a rotary column hub motor on the collection ship, makes the collection device start to work, and then continuously falls on the basket net on the uppermost layer with manganese nodules.
Fifthly, hoisting manganese nodules upwards:
when the number of the manganese nodules on the basket net reaches a rated value, workers on the control ship disconnect the power supplies of the two water pump hub motors and the rotary column hub motor, rotate corresponding lifting rope winches on the control ship, lift corresponding lifting ropes, and enable the basket net belt to ascend to the control ship along with the manganese nodules.
And repeating the fourth step and the fifth step until the n basket nets finish lifting.
The hawser winch is then activated, the collection vessel is hoisted back onto the handling vessel using the hawser, and the process is repeated.
After the structure is adopted, because no worker is arranged on the collection ship, all the work of the collection ship for collecting the manganese nodules in the deep sea is controlled by the worker on the control ship on the sea surface, the collection ship is safe, has low requirements on the structure of the collection ship, can obviously save investment, can be manufactured in batches, can collect a large number of manganese nodules, and can possibly generate better social benefit and economic benefit.
After the structure is adopted, the cabin is sealed, and the battery placed in the cabin is not eroded by seawater, so that the power supply can be reliably and safely supplied, the charging can be carried out for many times, and the electric vehicle can be used for a long time.
After adopting such structure, because collection system and guider cooperate each other well in coordination, the position that gathers the ship and arrives, gather the ship and can all gather the manganese nodule that the size is greater than the seabed of the horizontal width of tooth's socket, gather efficiently.
After the structure is adopted, the technical problem that the manganese nodule automatically falls onto the basket net is solved because the guiding device and the basket net are matched with each other and are better in cooperation.
After the structure is adopted, the hoisting rope, the rope ring, the basket net and the net ring on the hoisting device are matched with each other well, and the flattened basket net can be changed into a bag shape when the hoisting rope ascends, so that a manganese structure falling onto the basket net can be lifted onto a control ship, and the hoisting problem of the manganese structure is ingeniously solved.
After the structure is adopted, the n lifting ropes are orderly arranged in the rope clamp clamping groove according to the groove outlet sequence, so that the n lifting ropes can not become a pile of messy hemp, and conditions are created for the smooth groove outlet of the lifting ropes.
After adopting such structure, because replace the propeller with centrifugal water pump and use on the collection ship, carry out water jet propulsion to the collection ship, because the position of water pump installation is high again, solved the technical problem that the propeller rotation arouses silt to float everywhere and influence visibility.
After adopting such structure, because the cooperation of ship rope and rope pipe each other, solved and gathered the technical problem that the ship takes place to incline by a wide margin in the process of rising or subsiding.
After the structure is adopted, because the front part of the ship bottom is provided with the water leakage hole, the longitudinal middle part of the collection ship can not retain seawater in the water outlet process, so that the position of the gravity center of the collection ship can not be changed, and conditions are created for smooth water outlet
After the structure is adopted, the rope pipe and the ship rope are fixedly connected to the top plate right above the gravity center of the collecting ship, so that the bottom of the collecting ship can be kept in a horizontal state in the rising or settling process of the collecting ship in the static water.
The invention can not be perfectly beautiful, and the invention can not bring the brick to the motherland and expect the future to be continuously refined.
