2) the control platform sends a control signal for attracting fish shoals to the excitation regulation and control system 12, and the excitation regulation and control system 12 inputs voltages with opposite voltage directions and 20V voltage amplitudes to 8 groups of excitation devices 8 according to the signal for attracting fish shoals sent by the control platform, namely A, C, E, G and B, D, F, H are opposite in voltage direction;
3) the 8 groups of excitation devices 8 are excited to deform so as to generate force, and the pile foundation 9 is excited to generate vibration frequency to attract fish shoals;
4) the control platform sends a signal to a remote communication module on the motor 63, so that the motor 63 rotates by a certain angle, and the feed stored in the feed feeding device 6 falls into the sea to feed fishes;
5) after feeding fish for a plurality of times, maintainers can take the boat to the offshore working platform 5 and add feed, so that the subsequent use is convenient;
6) the excitation regulation system 12 is turned off so that the fish shoal is divergently swim.
8 small lattices are arranged in the feed box 61 on the offshore working platform 5, or more small lattices can be arranged according to actual needs so as to increase the feeding times, and enough feed for fish school to eat once is respectively placed in each small lattice and fed once every day; when feeding, the motor 63 rotates, so that the small lattices for storing the feed in the feed box 61 are aligned to the feed feeding channel 64, and the feed falls out completely for feeding.
The specific working mode is as follows: sea wind pushes the rotor wing 1 to rotate, the rotor wing 1 transmits mechanical energy to the wind generating set 2, and the mechanical energy is converted into electric energy after passing through the wind generating set 2 to supply power for the excitation regulation and control system 12 and the excitation device 8; through the remote control platform, the excitation regulation and control system 12 can be controlled, so that the excitation regulation and control system 12 regulates the voltage phase on each excitation device 8, the pile foundation 9 starts to be excited, the pile foundation 9 sends out sound waves 11 with different frequency spectrum characteristics under water, and different types of fish 10 are attracted to the sea area below the offshore working platform 5; the remote control platform controls the motor 63 to start working, so that the motor 63 rotates by a certain angle, and feeds are put into seawater; maintenance personnel can periodically go to the offshore platform 5 for maintenance, open the cover 67 and top up the feed in the feed box 61 for subsequent feeding.
The above embodiments are preferred embodiments, it should be noted that the above preferred embodiments should not be considered as limiting the present invention, and the scope of the present invention should be limited by the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and scope of the invention, and such modifications and improvements should be considered within the scope of the invention.
