The self-lifting tidal current flow blocking device for flood tide comprises a second connecting rope 3.1, a second flow blocking screen plate 3.3 positioned on the outer side of the aquaculture net cage, a second floating frame 3.2 floating on the water surface, a second floating frame counterweight 3.5 sinking to the sea bottom and a second anchor rope 3.6 connecting the second floating frame and the second floating frame counterweight. One side of the cultivation floating frame is provided with a second bracket 3.4. The second support and the first support are located on two opposite sides of the cultivation floating frame, the second support is located above the water surface, and a second guide ring is arranged on the second support. The second flow blocking net plate and the second bracket are positioned at the same side of the aquaculture net cage. The second floating frame and the second bracket are positioned at two opposite sides of the aquaculture net cage. The one end that the rope was connected to the second floats the frame with the second and is connected, and the other end that the rope was connected to the second passes the second guide ring and is connected with the upper end of second choked flow otter board. The upper end of the second flow blocking net plate is hung below the second guide ring through a second connecting rope. The second connecting rope is provided with a second upper limiting piece and a second lower limiting piece, and the second lower limiting piece is positioned below the second guide ring.
When the second flow-obstructing mesh plate is hung on the second guide ring through the second upper limiting piece on the second connecting rope, the upper edge of the second flow-obstructing mesh plate is positioned below the bottom surface of the aquaculture net cage or close to the bottom surface of the aquaculture net cage. When the second lower limiting piece abuts against the second guide ring, the upper edge of the second flow blocking net plate is close to the water surface.
When tide rises and the tidal current flow rate is smaller than a set value V1, the second flow-resisting net plate sinks downwards under the action of self weight until the second upper limiting piece abuts against the second guide ring, and at the moment, the second flow-resisting net plate is hung on the second guide ring through the second upper limiting piece on the second connecting rope. When the tidal current flow rate is larger than a set value V1, the second floating frame overcomes the gravity of the second flow blocking screen plate under the action of the tidal current, moves to the open sea along the tidal current, and drives the second flow blocking screen plate to move upwards through the second connecting rope until the second lower limiting piece abuts against the second guide ring.
Therefore, when tidal current flow velocity is smaller than a set value V1 during tidal current rise, the upper edge of the second flow blocking screen plate is positioned below or close to the bottom surface of the aquaculture net cage, so that tidal current can smoothly flow through the aquaculture net cage, and the problems that field domestication effect is influenced due to too small tidal current, and even fry in the cage are dead due to oxygen deficiency are avoided; when the tidal current flow rate is larger than a set value V1, the second floating frame overcomes the gravity of the second flow-blocking screen plate under the action of tidal current, so that the second flow-blocking screen plate moves upwards, the upper edge of the second flow-blocking screen plate is close to the water surface, the tidal current is blocked by the second flow-blocking screen plate, the tidal current flowing through the aquaculture net cage is reduced, the situation that the normal life of the east-sea large yellow croaker fry is influenced due to overlarge tidal current flowing through the aquaculture net cage is avoided, even the east-sea large yellow croaker fry is injured, and the survival rate is influenced is avoided
Furthermore, the second flow blocking screen plate comprises a second upper connecting plate, a second guide hole arranged on the second upper connecting plate, a second guide rod arranged in the second guide hole in a sliding manner, a second fixed screen plate and a second floating screen plate which are positioned below the second upper connecting plate, a second flow blocking plate positioned below the second floating screen plate, a second limiting plate arranged at the upper end of the second guide rod, a second limiting block arranged on the second guide rod and positioned between the second upper connecting plate and the second limiting plate, and a second compression spring positioned between the second upper connecting plate and the second limiting plate. The upper end of the second fixed screen plate is fixed on the second upper connecting plate. The second floating net plate, the second fixed net plate and the second guide rod are parallel to each other. The upper end of the second floating net plate is connected with the lower end of the second guide rod. The second compression spring is used for driving the second guide rod to move upwards until the upper end of the second fixed screen plate abuts against the second upper connecting plate. The second spoiler is perpendicular to the second guide rod and is connected with the second floating screen plate through a connecting piece. The other end of the second connecting rope is connected with a second upper connecting plate of the second flow blocking net plate. When the upper end of the second fixed screen plate is abutted against the second upper connecting plate, the meshes of the second floating screen plate are opposite to the meshes of the second fixed screen plate. The specific structure of the second screen plate of the present embodiment refers to the first screen plate in fig. 4.
When tide rises and the tidal current flow rate is greater than a set value V2, the acting force of the tidal current acting on the second spoiler overcomes the acting force of the second compression spring, so that the second floating screen plate axially moves along the second guide hole until the second limiting block abuts against the second upper connecting plate, and at the moment, the meshes of the second floating screen plate and the meshes of the second fixed screen plate are distributed in a staggered manner; the set value V2 is greater than the set value V1.
Therefore, when tidal current is greater than a set value V2, the set value V2 is greater than a set value V1, the acting force of the tidal current acting on the second spoiler overcomes the acting force of the second compression spring, and meshes of the second floating mesh plate and meshes of the second fixed mesh plate are distributed in a staggered manner, so that the flow resistance of the second mesh plate is further increased, the tidal current flowing through the aquaculture mesh box is further reduced, the problem that the normal life of the east-sea pseudosciaena crocea fry is influenced, even the east-sea pseudosciaena crocea fry is injured, and the survival rate is influenced is solved.
Of course, the second baffle plate of the present embodiment may also be formed by one plate.
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.
