In this embodiment, the float is further provided with a night light, such as a night light stick.
The third embodiment, the remaining structure of the present embodiment refers to the first or second embodiment, and the difference is that,
as shown in fig. 2, the floating tuna gathering device further comprises a gravity member 7.1 which is connected with the central buoyancy member through a suspension rope, and the gravity member is suspended below the central buoyancy member. Therefore, the stability of the floating tuna gathering device is improved, and the influence of sea wind, sea current and the like on the floating tuna gathering device is reduced.
The fourth embodiment is the same as the first embodiment, but the other structure of the present embodiment is different from the first embodiment,
as shown in fig. 3, the floating tuna gathering device further comprises an adaptive choke device, wherein the adaptive choke device comprises a gravity piece 7.1, a choke piece 7.5, a steel wire rope 7.3, a blocking piece 7.4 arranged in the middle of the steel wire rope, and a support ring 7.2 arranged at the bottom of the central buoyancy piece. In this embodiment, the gravity member is a gravity ball. The steel wire rope penetrates through the support ring, the gravity piece is fixed at one end of the steel wire rope, and the flow blocking piece is fixed at the other end of the steel wire rope. The spoiler comprises several spoiler panels 7.51. The obstruction is on the same side of the support ring as the flow obstruction. The stop cannot pass through the support ring.

The blocking piece is abutted against the supporting ring under the action of the gravity piece. The length of the steel wire rope is 30-60 meters, in the embodiment, the length of the steel wire rope is 30 meters, 40 meters or 50 meters.
In order to reduce the influence of sea wind, sea current and the like on the fish collecting device, a choke piece is generally hung below a drifting object, and because the drifting object floats on the sea surface, if the choke piece is close to the sea surface, the choke piece can synchronously flow along with the drifting object, and the choke effect is poor; therefore, the choke element can be preferably hung on a deeper sea layer through a rope, and the choke effect is improved through the water flow difference of the sea layers with different depths; however, in artificial drifting objects for gathering tunas, as tunas generally move with the drifting object in a water layer 30-100 meters deep below the drifting object, the chokes cannot be suspended in the sea layer below 30, generally 10-20, by ropes, otherwise the chokes interfere with gathering of the tunas on the one hand and catching in a purse net on the other hand. The self-adaptive flow blocking device can not interfere the gathering of the tunas under the condition of good weather conditions (in the weather with small storms and suitable for fishing), and effectively reduces the influence on the purse net fishing; in the weather with large wind waves (the wind waves are large and are not suitable for catching), the flow resisting pieces are made to fall to deeper sea layers, and the flow resisting effect is improved through the water flow difference of the sea layers with different depths, so that the influence of the wind waves and the like on the floating tuna gathering device is reduced; in particular, the method comprises the following steps of,
under the condition of good weather conditions (small stormy waves and weather suitable for fishing), because the flowing speed of the rubber inflatable floating ring is low, the flow resistance of the flow resisting piece is small, at the moment, the blocking piece is supported on the support ring under the action of the gravity piece, the steel wire rope is equivalently folded, the gravity piece and the flow resisting piece are positioned in a sea layer with the depth of 15-30 meters (because the tuna moves along with the drifting object in a water layer with the depth of 30-100 meters under the drifting object), therefore, the gathering of the tuna is not interfered, and the influence on the purse seine fishing can be effectively reduced. In the weather that the stormy waves are great, be not suitable for fishing, because sea water surface flow velocity is fast, the rubber aerifys the flow velocity of floating ring fast, the flow resistance that the choked flow piece received is great, this in-process, the choked flow piece will overcome the gravity and the flow resistance of gravity piece, make gravity piece up move, the choked flow piece descends, until the gravity piece supports on the support ring, at this moment, the choked flow piece will descend to deeper sea floor, through the rivers difference of different degree of depth sea floors, improve the choked flow effect.
In this embodiment, the spoiler further includes connecting rods 7.52 connecting each spoiler, and the connecting rods are vertically distributed, and each spoiler is parallel, and the spoilers are perpendicular to the connecting rods.
The buoyancy of the central buoyancy member is greater than the gravity of the adaptive flow blocking device. Therefore, the floating stability of the floating tuna collector is improved.
The length of the steel wire rope between the support ring and the blocking piece is larger than that between the support ring and the gravity piece. The difference between the length of the steel cable between the support ring and the blocking piece and the length of the steel cable between the support ring and the gravity piece is 0.5-1 meter.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
