In a further development of example 3, the same functions and effects as in the further development of example 2 are provided. Namely: the bottom of the floating body 4 is also provided with a damping baffle 43, and when the rotating disc 1 floats on the water surface through the floating body 4 and the power mechanism 42 drives the rotating disc 1, the damping baffle 43 enables the rotating disc 1 to rotate relative to the floating body 4 through the reaction force of water. And a generator 44 for charging the rechargeable battery 49 is provided on the float support 41, and the float 4 has a hollow structure and stores fuel supplied to the generator 44, so that the float support has a function of remote operation; and a plurality of oil separation plates 45 are uniformly arranged in the floating body 4 at intervals, and slow flow holes 451 for enabling the fuel oil on two adjacent sections of the oil separation plates 45 to smoothly flow are arranged on the oil separation plates 45.

As inventive example 4:

The difference between this embodiment and the above embodiment is that the device comprises a rotating upright post 8 and a flexible driving belt 9, the rotating upright post 8 is rotatably connected to the deck of the ship, the upper portion of the rotating upright post 8 is provided with a bracket manipulator 81, the upper end of the bracket manipulator 81 is provided with a circular ring inserting opening 82 for supporting the rotating disc 1, when the rotating upright post 8 is controlled to rotate, the bracket manipulator 81 rotates along with the rotating upright post, the rotating disc 1 is circumferentially provided with an annular groove 13, one end of the flexible driving belt 9 is a fixed end and is fixedly connected to the bracket manipulator 81 and rotates along with the rotating upright post 8, the other end of the flexible driving belt 9 is a free end and is used for winding on the annular groove 13, and when the rotating upright post 8 drives the bracket manipulator 81 to rotate instantaneously, the rotating disc 1 on the bracket manipulator 81 is correspondingly thrown out, at the same time, the flexible driving belt 9 pulls the rotating disc 1 to rotate and fly out, and when the rotating disc 1 rotates to a preset rotation speed, the fishing net 2 and the counterweight 21 overcomes the constraint force of the binding assembly 3 to loosen the fishing net 2, and the net 2 is opened under the traction action of the counterweight 21, so that a net space 22 is formed.

As an improvement of this embodiment, the vortex fan 7 is disposed in the rotating disc 1, so that the rotating disc 1 rotates in an accelerating manner when falling freely in the air after the initial rotation speed, and a wireless controller is disposed, when the rotating disc 1 rotates to the preset rotation speed, the fishing net 2 and the counterweight 21 release the fishing net 2 against the constraint force of the binding assembly 3, so that the fishing net 2 is opened to form the net capturing space 22 under the traction action of the counterweight 21, and when in practical implementation, the net capturing space is accessed through the falling sonar fish detector, so as to detect the fish condition, and then net captured fish information is sent to the corresponding ship.

In the above embodiments 1, 2, 3, and 4, for a small amount of fish collecting modes, the fish shoal can directly take off, translate and pull the fishing net through the coaxial rotor craft 5 or the multiaxial rotor craft 6, so that the fish shoal enters the fishing net anti-pocket area at the tail end of the fishing net, and then take off, return to the deck of the ship, put down and hover, and manually take out the fish shoal and put into the fish protector; for a large number of fish collecting modes, the coaxial rotor craft 5 or the multiaxial rotor craft 6 cannot lift and fly directly, so that a ship can wait for using a large-area pull net to pick up a fish shoal trapped in advance by a fishing net, and after the large net finishes trapping a closed area, a small amount of fish shoal is pulled out to fly back to the deck of the ship through the coaxial rotor craft 5 or the multiaxial rotor craft 6. Before the fishing net is caught next time, the fishing net is bound on the rotating disc through the binding component 3 again according to the fishing net folding mode, and the fishing net which is folded is correspondingly borne by the tray so as to avoid scattering.

In order to effectively monitor a target object before net capturing, a periscope and/or a sonar fish detector 46 is arranged at the bottom of a floating body bracket 41, when a coaxial rotor aircraft 5 or a multiaxial rotor aircraft 6 carries a rotating disc 1 which completes folding and binding of a fishing net to fly to a destination to hover, the rotating disc is on or close to the water surface, the periscope or the sonar fish detector is firstly placed down, the lifting height of the periscope or the sonar fish detector is controlled by a miniature winch, and when fish is found to be gathered in a water area below the rotating disc, a fish gathering image can be visually seen by a handheld mobile control terminal; then, hovering and rotating can be carried out after taking off so as to carry out net broadcasting; or the control adapter 51 is separated from the clutch connection part 121, the power mechanism 42 is started to drive the rotating disc 1 to reach the preset rotating speed, and the fishing net is loosened to open to form the net capturing space 22 to trap the target object.

Further, the bottom of the floating body bracket 41 is provided with a spotlight 47 and/or a bait casting box 48, when the coaxial rotor craft 5 or the multiaxial rotor craft 6 carries the rotating disc 1 which is folded and bound with the fishing net to fly to a destination to float in water, a periscope or a sonar fish detector is lowered, and no fish is found, at this time, the bait can be cast through the bait casting box 48 and/or the fish can be attracted by opening the spotlight 47 for trapping.

In the utility model, the turbofan 7 is arranged in the rotating disc 1, and the main purpose is that when the coaxial rotor aircraft 5 or the multiaxial rotor aircraft 6 fly to the air with the rotating disc 1 with the binding fishing net to be separated from the rotating disc, the fishing net is still in a binding state, therefore, the rotating disc 1 needs to rotate continuously and faster, the turbofan 7 can accelerate the rotating disc 1 which generates free falling, namely, the angle of the windward side of the fan blade of the turbofan 7 gradually changes to guide the air to flow to the central shaft hole of the intersection point of the fan blade of the turbofan 7 to be intensively flushed. The fan blade of the turbofan 7 has relatively high thickening and moderate relative bending; the leading edge of the blade is relatively thick and rounded to reduce aerodynamic losses and drag, and the trailing edge of the blade is relatively thin and sharp to reduce turbulence generation and improve the overall quality of the airflow.

Moreover, the thickness of the wing profile of the blade of the turbofan 7 varies with distance from the blade root, specifically, the root is thicker to bear larger load and rotation speed, and the tip part is thinner to reduce resistance and improve flow field distribution. In addition, the curvature radius of the upper surface of the front edge airfoil of the fan blade 7 of the turbofan is smaller so as to generate higher suction effect, which is helpful for improving the lift force and efficiency of the fan blade; the rear edge of the fan blade of the turbofan 7 has a certain bending degree, which is called rear edge bending degree, and the rear edge bending degree can reduce peak resistance and turbulent flow generation and improve the aerodynamic performance of the fan blade.

In addition, in order to facilitate the net capturing operation net collecting, the rotating disc is correspondingly provided with wireless communication and satellite positioning signals so as to carry out tracking positioning, and the following performance requirements are also met for the coaxial rotor craft 5 or the multiaxial rotor craft 6 which are required to cooperate with each other:
