Description

Technical Field

[0001] The present invention relates to the technical field of aquatic product breeding and marine engineering, and in particular to a cage floating system and a purse seine type cage. Background Art

[0002] In order to save costs, most of the cages in the prior art are small cages, and their materials are mostly plastic, foam, wood, etc., which have poor resistance to large wind and waves in the open sea. Due to the periodic rise and fall of the tide in the open sea, it has a certain self-purification ability. As a transition form to offshore aquaculture, it still has a certain utilization value. From this, aquaculture tools in shallow waters have been derived. The most common one is a fence-type cage created by the people. The piles are driven into the seabed by the piling method, and then surrounded by nets to become a fixed cage that cannot be moved at will. This method of piling in the ocean is costly and unsafe.

[0003] For example, in the invention patent with the patent number "201510370218.0" and the name "A soft and hard deep-sea cage resistant to wind and waves", a soft protection ring is arranged around the cage, and six floats are evenly arranged on the soft protection ring. The force on the cage is buffered and alleviated by the traction force of the soft protection ring, thereby resisting the direct impact of wind and waves on the cage. However, the overall non-detachable structure of the soft protection ring is large, which makes the processing and installation time-consuming and labor-intensive, and the soft protection ring structure is light and easily damaged. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems and provide a cage floating system and a purse seine cage, which do not require piling and support systems, and the entire cage floating system is assembled to make the construction extremely convenient and quick, and is suitable for continental shelf oceans with various water depths and bottom conditions, and effectively improves the safety and stability of the entire cage under wind and wave conditions.

[0008] Preferably, mooring piles are respectively provided at both ends of the floating body, and cables are fixed on each mooring pile, and each cable is used to connect the floating body and the connecting plate adjacent to the floating body.

[0009] Preferably, both the floating body and the connecting plate are trapezoidal structures with an outer side length greater than an inner side length, so as to ensure uniform spacing between edges of adjacent floating bodies and connecting plates.

[0010] Preferably, the upper end of the floating body and the connecting plate are higher than the highest water level, the upper end of the floating body is used for personnel activities and material storage, and the connecting plate is used for personnel passage.

[0011] Preferably, a purse seine cage is provided, further comprising a suspended purse seine system and an anchor system, wherein the suspended purse seine system comprises a closed net and a detachable mechanism disposed on the annular structure and used to fix the net, and the anchor system is used to fix the positions of the cage buoyancy system and the suspended purse seine system in the water.

[0012] Preferably, the net includes side nets arranged around each of the annular structures and a top net detachably connected to the side nets, the side nets include an upper opening and a lower opening, the top net is used to close the upper opening, and the top net is provided with a float for making the top net float on the water surface.

[0016] 1. The two ends of the connecting plate are hinged with the floating body through the holes and the vertical axis. The connecting plate can rotate around the floating body in the horizontal direction. The relative movement of the two can buffer the impact of wind and waves on the cage floating system and avoid the cage floating system from being too rigid and prone to breakage.

[0017] 2. The socketed holes and vertical axis restrict the connection plate to rotate only in the horizontal direction around the floating body, thereby restricting the relative movement between the floating body and the connection plate in the vertical direction, thereby improving the stability of the connection between the floating body and the connection plate.

[0018] 3. The adjacent floating bodies and connecting plates are connected by cables, which can not only fully limit the horizontal rotation angle between the floating bodies and the connecting plates, avoiding the deformation of the entire annular structure to affect the space inside the net, but also limit the amplitude of the relative movement between the adjacent floating bodies and the connecting plates, avoiding damage to the vertical axis and separation of the hole from the vertical axis.

[0019] 4.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a cage floating system and a purse seine cage, which do not require piling and support systems, and the entire cage floating system is assembled to make construction extremely convenient and quick, and is suitable for continental shelf oceans with various water depths and bottom conditions, and effectively improves the safety and stability of the entire cage under wind and wave conditions.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment provides a cage float 3 system, including a plurality of floats 3 and a connecting plate 4 erected between two adjacent floats 3, and the floats 3 and the connecting plate 4 are connected to form a ring structure. Among them, the float 3 supports its own weight and the weight of the net 8 by its own buoyancy, and the float 3 can be selected in any shape according to the sea conditions, and is usually circular, rectangular or boat-shaped, and its upper end is higher than the highest water level, which is used to provide a place for personnel activities and material storage in the fishery base. Preferably, when the float 3 is in the shape of a boat, the deck is higher than the highest water level at high tide, and preferably, the float 3 is a steel ship, or is made of wire mesh cement or wire mesh concrete. Whether it is made of steel or wire mesh cement or wire mesh concrete, it should be designed and constructed in accordance with the national ship construction specifications. Pedestrian railings are set on the edges of the decks on both sides, and auxiliary rooms such as tool rooms, storage rooms, lounges, and conference rooms required for aquaculture can also be set on the float. The connecting plate 4 is also higher than the highest water level and is used for people to pass. Preferably, the connecting plate 4 is a steel frame structure, for example, made of steel or wire mesh cement or wire mesh concrete. To simplify the design, the plane shape of the connecting plate 4 is generally designed to be a trapezoid or a rectangle, on which anti-slip wooden boards, plastics or flower steel plates are laid for people to walk, and pedestrian railings are set on the edges of the connecting plate 4 on both sides. Furthermore, in order to ensure the convenience of assembly between the floating body 3 and the connecting plate 4, holes and vertical axes that are connected to each other are respectively provided at both ends of the connecting plate 4 and the floating body 3. For example, vertical axes 6 are respectively provided at both ends of the floating body 3, and holes with vertical axes are respectively opened at both ends of the connecting plate 4. Preferably, a fastening device 10, such as a bolt or other structure, is provided. After the hole is sleeved on the vertical axis 6, the hole is fixed on the vertical axis 6 by the fastening device 10. Further preferably, a fixed bracket 11 is provided on the side walls at both ends of the floating body 3, and the vertical axis 6 is provided at the upper end of the fixed bracket 11. The connecting plate 4 is sleeved on the vertical axis through the hole, so that a hinge is formed between the connecting plate 4 and the floating body 3, and it is integrally overlapped and mounted on the fixed brackets 11 of two adjacent floating bodies 3, that is, its weight is supported by the buoys at both ends, and then the connecting plate 4 can rotate around the floating body 3 in the horizontal direction through the vertical axis, which can not only buffer the impact of wind and waves on the cage floating body 3 system, but also improve the stability of the connection between the floating body 3 and the connecting plate 4.

[0032] In order to reduce the impact force generated between the float 3 and the connecting plate 4, a flexible connecting device 5 is provided between the float 3 and the connecting plate 4, such as a rubber leaning ball or an old tire leaning handle, etc. The rubber leaning ball or the old tire leaning handle is a commonly used anti-collision device and can be purchased on the market. In this example, it is used as a flexible connecting device 5 between the float 3 and the connecting plate 4 to ensure the smooth and safe pedestrian passage at sea. Preferably, in order to ensure that the float 3 and the connecting plate 4 are respectively stably connected with the flexible connecting device 5, a base and a connecting chain that can fix the flexible connecting device 5 are respectively provided at both ends of the float 3 and the connecting plate 4.

[0033] In order to prevent the entire annular structure from being greatly deformed by wind and waves and thus affecting the space inside the net 8, cables 9 are also connected between adjacent floats 3 and connecting plates 4, so as to fully limit the horizontal rotation angle between the floats 3 and the connecting plates 4. Preferably, mooring piles 7 are respectively provided at both ends of the float 3, and cables 9 are fixed on each of the mooring piles 7. The cables 9 are directly fixed on the main body of the connecting plate 4, or mooring piles 7 are also respectively provided at both ends of the connecting plate 4. The two ends of the cable 9 are respectively fixed on the mooring piles 7 of the adjacent floats 3 and the connecting plates 4. Moreover, the connection between the floats 3 and the connecting plates 4 by the cables 9 can also limit the amplitude of the relative upward and downward movement between the adjacent floats 3 and the connecting plates 4, thereby preventing the vertical axis 6 from being damaged and the hole from being separated from the vertical axis 6.

[0034] Furthermore, in order to reduce the pressure when adjacent buoys 3 and connecting plates 4 are squeezed against each other, both the buoys 3 and connecting plates 4 are trapezoidal structures with an outer side length greater than an inner side length, so as to ensure that the spacing between the edges of adjacent buoys 3 and connecting plates 4 is uniform. Then, after the flexible connecting device 5 is arranged between the buoys 3 and the connecting plates 4, the flexible connecting device 5 will not be affected by excessive pressure in a certain part between the buoys 3 or the connecting plates 4. For example, when the buoys 3 and the connecting plates 4 are both rectangular structures, after the two form a ring structure, the place where the distance between the two is the smallest is the position corresponding to the two sharp corners. Then, after the buoys 3 and the connecting plates 4 are impacted by wind and waves, the two sharp corners act on the flexible connecting device 5 at the same time, which is bound to easily cause the flexible connecting device 5 to be damaged prematurely by the impact of the two sharp corners. Then, the present invention preferably sets the buoys 3 and the connecting plates 4 to be trapezoidal structures with an outer side length greater than an inner side length, precisely to avoid the occurrence of the above-mentioned situation, thereby making the edges between the two evenly correspond, thereby extending the service life of the flexible connecting device 5.

[0035] As a preferred embodiment of the present invention, the size of the cage float 3 system provided in the above embodiment is further limited. The cage float 3 system is set as a circular sleeve, and the diameter D of the circular sleeve is 100m. It is composed of sixteen groups of floats 3, flexible connecting devices 5 and connecting plates 4. The pontoon is a barge, and the deck plane is trapezoidal, with an outer side length of 9.676m, an inner side length of 9.204m, a ship width d2.5m, a molded depth of 1.6m, and a draft of 1.1m. Railings with a height of 1.1m are set on both sides of the deck. As a preferred embodiment of the present invention, the connecting plate 4 of the cage float 3 system is trapezoidal in plane, with an outer side length of 9.630m, an inner side length of 9.250m, and a ship width of 2.0m. The channel steel specification of the connecting plate 4 is 25b (250*80*9, 31.335kg / m). Preferably, a non-slip plastic plate is laid on the connecting plate 4, and 1.1m high railings are set on both sides.

[0036] This embodiment also provides a purse seine type net cage, including the net cage floating system, the suspended purse seine system and the anchor system as in the above embodiment, the suspended purse seine system includes a closed net 8 and a detachable mechanism arranged on a ring structure and used to fix the net 8, preferably, the upper end of the net 8 is tied with a steel wire rope, and the steel wire rope is hung on a hook located on the floating body 3 or the connecting plate 4, and the steel wire rope of the net 8 is tied to the hook with a short rope to prevent it from falling off. The anchor system is used to fix the position of the net cage floating system and the suspended purse seine system in the water, without the need for piling and supporting systems, making the construction extremely convenient and quick.

[0037] The net 8 includes side nets arranged around each annular structure and a top net detachably connected to the side nets. The side nets include an upper opening and a lower opening. The top net can be arranged on the water surface in the annular structure to close the upper opening. Preferably, the top net is also connected to the net box body by a rope. When there is no typhoon or the wind and waves are small, the staff can remove the top net from the side nets and store it in the floating body 3. When the wind and waves are large, the top net is installed on the side nets and can cover the water surface in the annular structure to prevent fish from escaping outside the net box body and causing unnecessary losses. At the same time, the top net is provided with a floating object for making the top net float on the water surface.

[0038] Furthermore, the net 8 includes a bottom net for closing the lower opening, or a number of weights are evenly fixed at the bottom of the side net, which drive the bottom to sink to the bottom of the water to close the lower opening. When in shallow waters, the bottom of the side net can be sunk to touch the seabed by the weights. In this case, the bottom net may not be set to avoid a gap between the net 8 and the bottom of the water. If the water is deep, a bottom net must be set to close the lower opening of the side net.

[0039] Meanwhile, the anchor system includes an anchor 1 and an anchor chain 2 or an anchor cable arranged between the anchor 1 and the annular structure. The anchor system is determined by theoretical calculation or model test based on the ocean waves of the maximum wind level in the sea area where the annular structure is located. Preferably, the anchor chain 2 is selected as the connection between the anchor 1 and the annular structure. After the force of the annular structure in a certain sea area is determined, the anchor chain 2 is generally selected according to the catenary theory. Preferably, the arrangement of the anchor system can generally be divided into two cases, one is arranged according to the wind direction, that is, the maximum probability direction of the wind direction of the maximum wind level in the sea area where the annular structure is located is set as the arrangement direction of the main anchor system, and the other is evenly arranged around the annular structure, that is, the wind direction of the maximum wind level is not considered. Preferably, when the arrangement of the net box and the force of the anchor chain 2 are determined, a conventional anchor or a large grip anchor can generally be selected according to the ship specification, such as the anchor disclosed in the patent number ZL201720440879.0 and the name "A Gravity-type Ocean Wind Measurement Tower".
