Description

Technical Field

[0001] The present invention relates to a ship-shaped cage system in the technical field of marine aquaculture, in particular to a split ship-shaped cage system. Background Art

[0002] In recent years, my country has paid more and more attention to marine resources. As an important application of marine aquaculture, ship-shaped cages have an important significance in the utilization of marine resources.

[0003] However, due to the impact of waves in the open sea, marine facilities such as cages and platforms may be damaged, causing economic losses. This requires that the ship-type cages have a lifting function. When the sea waves are too strong and the seawater flow rate is too high, the cages can be sunk into the relatively calm deep sea to avoid irreversible damage such as bending and breaking of the cage frame.

[0004] However, the ship-shaped cages in the prior art still have the following technical problems: It is difficult to sink a ship-shaped cage. During the sinking process, the overall water-entry posture of the ship-shaped cage is difficult to control, which can easily cause it to tilt and lead to damage to the cage structure.

[0005] Therefore, the applicant proposes the present invention. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art and to provide a split ship-shaped cage system capable of controlling the overall entry posture of the cage into the water during the sedimentation process.

[0007] In order to achieve the above-mentioned purpose, the present invention is designed to have a split-type ship-shaped cage system, including a rectangular frame system, a net system, a counterweight system and a single-point mooring system, wherein: The side where the width and height of the rectangular frame system are located is the wave-facing side, and a bow system is provided on the wave-facing side of the rectangular frame system. The rectangular frame system and the bow system are fixed in a detachable manner, and the two are arranged in a line; a control system is provided on the bow system; The net system is distributed along the outer contour of the rectangular frame system and encloses a rectangular cage breeding area; The counterweight system includes a compressed air system and a sinker; The sinkers are connected to the bottom of the net system and are distributed along the outer contour of the net system; a cavity and a water flow channel are formed on each sinker, and the cavity is communicated with the outside through the water flow channel, and an electric regulating valve or a signal valve is provided on the water flow channel to switch the on-off state of the water flow channel; The air compressor of the compressed air system is installed on the bow system, and the cavities of all sinkers are independently connected to the pipeline system of the compressed air system, and an electric regulating valve or a signal valve is arranged on the pipeline system to control the cavities of different sinkers to be injected or exhausted through the pipeline system individually or in combination; The single point mooring system is located on the wave-facing side of the bow system and is interconnected with the bow system; The control system is electrically connected to the compressed air system, electric regulating valve or signal valve one and electric regulating valve or signal valve two respectively. It controls the working state of the compressed air system and the on-off state switching of the electric regulating valve or signal valve one and the electric regulating valve or signal valve two to realize the exhaust and water injection of the sinker from one side to the other side in the length direction of the ship-type cage system, thereby controlling the entry posture of the ship-type cage system during the sinking process.

[0008] When the wind and waves are too strong and exceed the wave-breaking and wave-resisting capabilities of the present invention, the rectangular frame system and the bow system of the split ship-shaped cage system of the present invention can be detached; in addition, the present invention can control the sinkers to exhaust and inject water from one side to the other side in the length direction of the ship-shaped cage system, that is, to change the mass of the local sinkers in sequence, so that the ship-shaped cage system can enter the water in a step-by-step manner, and then control the entry posture of the ship-shaped cage system during the sinking process, effectively preventing the ship-shaped cage system from tilting during the sinking process. Therefore, the present invention cleverly solves the problems of the traditional ship-shaped cage system that the entry speed and the entry posture cannot be controlled, and the cage structure (such as the bending cage frame) is easily damaged, and realizes the protection of the ship-shaped cage system when the wind and waves are strong.

[0009] Among them, the ship-shaped cage system of the above structural design can realize the mechanical principle of step-by-step entry into the water during the settlement process, as follows: During the entire settling process of the ship-shaped cage system, the later settling part always applies a balanced pulling force to the earlier settling part on a pair of sides where the length and width of the ship-shaped cage system are located to avoid the ship-shaped cage system from tilting, and the part of the ship-shaped cage system that has already settled will apply the same pulling force to the later settling part.

[0010] As a preferred technical solution, the above-mentioned split ship-shaped cage system has a structure in which: The rectangular frame system is divided into a plurality of rectangular frame units arranged in a line; The net system corresponding to each rectangular frame unit forms an independent rectangular cage breeding area; The sinkers of the counterweight system are located at the four corners of each rectangular cage culture area.

[0011] The different rectangular cage culture areas in the above preferred technical solution achieve the purpose of mixed culture of multiple marine organisms. Further, considering that the rectangular cage culture area in the front direction of the waves can reduce waves and block the flow for the rectangular cage culture area behind, it is possible to adapt the cultured organisms according to the culture environment in different rectangular cage culture areas.

[0012] In order to simplify the detachable fixing structure between the rectangular frame system and the bow system, thereby improving the convenience of operation and structural stability, the above-mentioned split ship-shaped cage system, in which the detachable fixing structure between the rectangular frame system and the bow system is preferably selected to include: A connector mounted on the rectangular frame system; an end of the connector forms a locking mouth; A double screw mechanism is installed on the bow system; the two sliders in the double screw mechanism are locking blocks and always move in opposite directions; The two locking blocks of the double screw mechanism move toward each other until they are engaged in the locking openings of the connecting piece to achieve mutual locking of the rectangular frame system and the bow system.

[0013] When the sea waves are too strong and the seawater flow rate is too high, the two screw motors of the double screw mechanism are controlled to drive the corresponding locking blocks to move in reverse, that is, the two locking blocks are separated and unlocked, and then the force applied to the ship-type cage system by the ocean wind and waves is combined to complete the separation of the bow system and the rectangular frame system.

[0014] Compared with the prior art, the split ship-shaped cage system obtained by the present invention has the following technical effects: When the wind and waves are too strong and exceed the wave-breaking and wave-resisting capabilities of the present invention, the rectangular frame system and the bow system of the split ship-shaped cage system of the present invention can be separated; in addition, the present invention can control the sinkers to exhaust and inject water from one side to the other side in the length direction of the ship-shaped cage system, that is, to change the mass of the local sinkers in sequence, so that the ship-shaped cage system can enter the water in a step-by-step manner, thereby controlling the entry posture of the ship-shaped cage system during the sinking process. Therefore, the present invention cleverly solves the problems of the traditional ship-shaped cage system that the entry speed and the entry posture cannot be controlled, and the cage structure (such as the bending cage frame) is easily damaged, and realizes the protection of the ship-shaped cage system when the wind and waves are strong.

[0015] Considering that the front rectangular cage culture area of ​​the present invention can reduce waves and block current for the rear rectangular cage culture area in the wave-facing direction, the present invention can adapt the cultured organisms according to the culture environment in different rectangular cage culture areas.

[0019] like Figure 1 and Figure 2 As shown, as an embodiment of the present invention, a split ship-type cage system provided in this embodiment includes a rectangular frame system 1, a net system 2, a counterweight system and a single-point mooring system 3, wherein: The side where the width and height of the rectangular frame system 1 are located is the wave-facing side, and a bow system 4 is provided on the wave-facing side of the rectangular frame system 1. The rectangular frame system 1 and the bow system 4 are fixed in a detachable manner, and the two are arranged in a line; a control system (not shown in the figure) is provided on the bow system 4; The net system 2 is distributed along the outer contour of the rectangular frame system 1 and encloses a rectangular cage breeding area; The counterweight system comprises a compressed air system 5 and a sinker 6; The sinkers 6 are connected to the bottom of the net system 2 and are distributed along the outer contour of the net system 2; each sinker 6 is formed with a cavity 6-1 and a water flow channel 6-2, and the cavity 6-1 is communicated with the outside through the water flow channel 6-2, and an electric regulating valve or a signal valve 1 (not shown in the figure) is provided on the water flow channel 6-2 to switch the on-off state of the water flow channel 6-2; The air compressor 5-1 of the compressed air system 5 is installed on the bow system 4, and the cavities 6-1 of all sinkers 6 are independently connected to the pipeline system 5-2 of the compressed air system 5, and an electric regulating valve or a signal valve 2 (not shown in the figure) is arranged on the pipeline system 5-2 to control the cavities 6-1 of different sinkers 6 to be individually or in combination injected or exhausted through the pipeline system 5-2; The single point mooring system 3 is located on the wave-facing side of the bow system 4 and is interconnected with the bow system 4; The control system is electrically connected to the compressed air system 5, the electric regulating valve or signal valve 1 and the electric regulating valve or signal valve 2 respectively. It controls the working state of the compressed air system 5 and the on-off state switching of the electric regulating valve or signal valve 1 and the electric regulating valve or signal valve 2 to realize the sinker 6 to exhaust and fill water from one side to the other side in the length direction of the ship-type cage system, thereby controlling the entry posture of the ship-type cage system during the sinking process.

[0020] The rectangular frame system 1 in this embodiment is divided into a plurality of rectangular frame units arranged in a line; The net system 2 corresponding to each rectangular frame unit forms an independent rectangular cage breeding area; The sinkers 6 of the counterweight system are located at the four corners of each rectangular cage culture area.

[0021] The above-mentioned different rectangular cage aquaculture areas achieve the purpose of mixed aquaculture of multiple marine organisms. Further, considering that the rectangular cage aquaculture area ahead in the wave-facing direction can reduce waves and block currents for the rectangular cage aquaculture area behind, it is possible to adapt the aquaculture organisms according to the aquaculture environment in different rectangular cage aquaculture areas.

[0022] In order to realize the detachable fixing structure between the rectangular frame system 1 and the bow system 4 by simplifying the fixing structure, thereby improving the convenience of operation and the stability of the structure, such as Figure 3 As shown, the detachable fixing structure between the rectangular frame system 1 and the bow system 4 in this embodiment includes: A connecting member 7, which is mounted on the rectangular frame system 1; the end of the connecting member 7 forms a locking opening 7-1; A double screw mechanism 8 is mounted on the bow system 4; the two sliders in the double screw mechanism 8 are locking blocks 8-1 and always move in opposite directions; The two locking blocks 8 - 1 of the double screw mechanism 8 move toward each other until they are engaged in the locking opening 7 - 1 of the connecting member 7 to achieve mutual locking of the rectangular frame system 1 and the bow system 4 .

Therefore, the present invention cleverly solves the problems of the traditional ship-shaped cage system that the entry speed and the entry posture cannot be controlled, and the cage structure (such as the bending cage frame) is easily damaged, and the protection of the ship-shaped cage system is achieved when the wind and waves are strong.

[0025] When the sea condition returns to calm, that is, the wind and waves are small and the water flow rate is low, the control system of the ship-type cage system of the present invention only needs to control the working state of the compressed air system 5 and the on-off state switching of the electric regulating valve or signal valve 1 and the electric regulating valve or signal valve 2 again to realize the air injection and drainage of all sinkers 6, that is, to change the mass of the sinkers 6, and the rectangular frame system 1 of the ship-type cage system can rise to the water surface again, together with the net system 2.
