Description

Technical Field

[0001] The present invention relates to the field of design and manufacturing of Antarctic krill fishing vessels, and in particular to an automatic truss retraction and deployment system for Antarctic krill vessels. Background Art

[0002] In Antarctic krill fishing, traditional truss deployment and retraction are primarily achieved through wire rope winches. Due to the deck placement of the truss and wire rope winches, as well as the operating range, the truss is subjected to significant forces at the initial deployment and retraction angles, creating dead zones for tension and thrust. This results in a long truss deployment cycle, making the process inefficient and posing serious safety risks. Traditional truss deployment methods often struggle to adapt to the changing fishing environment, resulting in low fishing efficiency and high operating costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to propose an automatic retractable and deployable system for Antarctic krill vessel trusses, which can realize the rapid, safe and precise deployment, recovery, lifting and lowering of the trusses, avoid the dead angles of tension and thrust during the deployment and recovery process, reduce manpower requirements and improve work efficiency.

[0004] In order to solve the above technical problems, an automatic retractable and retractable truss system for Antarctic krill boats is proposed, comprising a truss, a drive device, a hydraulic system, and an intelligent control system. The truss includes a truss body, a rotating body, a base, a mounting plate and a lifting lug. The base is installed on the deck structure. The rotating body is connected to the base and the truss body in the form of a pin / hinge transmission. The mounting plate and the lifting lug are respectively arranged on the truss body. The mounting plate is connected to the piston rod of the thrust cylinder, and the lifting lug is connected to the wire rope and the wire rope winch. The driving device includes the thrust cylinder, a wire rope winch and a wire rope, and the wire rope winch is installed on both sides of the truss; The hydraulic system is arranged near the truss body on the deck, its hydraulic output system is connected to the thrust cylinder, and its control system is connected to the sensor network and communication module; The intelligent control system includes a PLC module, a communication module and an operation terminal; The sensor network includes a position sensor, a torque sensor, an angle sensor and a sensor network.

[0005] Furthermore, the rotating body allows rotation with six degrees of freedom.

[0006] The optimized, intelligent control system also includes an audible and visual alarm system.

[0007] (1) Strong adaptability. The present invention uses a rotary truss device and equipment such as a thrust cylinder and a wire rope winch to achieve rapid deployment and recovery of the truss, which helps ships operate flexibly in complex sea conditions and improves fishing efficiency. The present invention uses a combination of a thrust cylinder, a horizontal rotating body, and a vertical rotating body to achieve rapid adjustment of the truss in three directions, thereby improving the flexibility of fishing operations.

[0008] (2) High degree of automation. The deployment and recovery process of the truss of the present invention is realized by automated equipment, which reduces the difficulty and complexity of manual operation.

[0009] (3) Low maintenance costs. Since manual operations are reduced, the chance of damage caused by human error is reduced. At the same time, intelligent systems can help predict and prevent potential failures, perform maintenance in advance, and reduce long-term operating costs.

[0010] (4) Enhanced safety. The intelligent control system can monitor environmental conditions and truss status in real time to ensure that deployment or retraction operations are not performed under unsuitable conditions, thereby ensuring the safe operation of the equipment and the safety of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0012] Figure 1 This is a general assembly diagram of the Antarctic krill vessel truss retracting and deploying system on the deck of the present invention.

[0013] Figure 2 This is the main view of the truss body.

[0014] Figure 3 This is a top view of the truss body. DETAILED DESCRIPTION

[0015] Combine Figure 1 、 2 As shown in Figure 3, the automatic retracting and extending system of the truss of the Antarctic krill ship of the present invention includes 1-truss, 2-thrust cylinder, 3-wire rope winch, 4-wire rope, 5-intelligent control system, 6-wind speed sensor, 7-position sensor, 8-torque sensor, 9-angle sensor, 10-hydraulic system, and 11-sound and light alarm system.

[0016] The truss 1 comprises a truss body 12, a rotating body 13, a base 14, a mounting plate 15, and a lifting lug 16. The base 14 is mounted on the deck structure, and the rotating body 13 connects the base 14 and the truss body 12 via a pin / hinge transmission, allowing for six degrees of freedom of rotation. The truss body 12 is provided with a mounting plate 15 and a lifting lug 16. The mounting plate 15 is connected to the piston rod of the thrust cylinder 2, while the lifting lug 16 is connected to the wire rope 4 and the wire rope winch 3. By applying an external force, such as cylinder thrust / tension, the rotating body 13 can achieve angular rotation of the truss body 12 in the horizontal plane, thereby enabling deployment and retraction. By retracting and releasing the wire rope via the wire rope winch, the truss body 12 can be angularly rotated in height, thereby enabling lifting and lowering.

[0017] The thrust cylinder 2, wire rope winch 3, and wire rope 4 are the driving devices that primarily power the horizontal deployment and retraction, as well as the lifting and lowering of the truss 1. The thrust cylinder 2 is located on one side of the truss 1, slightly aft of the ship. The wire rope winch 3 is mounted on either side of the truss, with both ends of the wire rope 4 connected to the lifting lugs 16 on the truss body 12. The thrust cylinder 2 and wire rope winch 3 precisely control the speed and direction of the deployment, retraction, lifting, and lowering of the truss 1, ensuring smooth and orderly operation. They are also capable of bearing the weight of the truss and its accessories, as well as the impact of seawater on the truss 1, ensuring its stability and safety.

[0018] The hydraulic system 10 is located near the truss body 12 on the deck. It consists of a hydraulic pump station and its associated motor, valve block, and oil tank. It ensures smooth and precise movement of the truss 1 during operation, preventing impact forces caused by rapid starts and stops. Its operating principle is to adjust the hydraulic system 10's start and stop operations and maintain constant flow and pressure by opening and closing multiple valve blocks, increasing and decreasing flow and pressure, based on truss-related data provided by network sensors and communication modules. This ensures stable output and operation of the thrust cylinder 2 and wire rope winch 3.

[0019] The intelligent control system 5 integrates and includes a PLC module, a communication module, an operation terminal, and an audible and visual alarm system 11. The intelligent control system 5 uses a touchscreen console as its terminal, located on the deck opposite the truss 1. The sensor network includes a wind speed sensor 6, a position sensor 7, a torque sensor 8, and an angle sensor 9. This sensor network monitors the truss 1's status in real time and provides feedback. The communication module collects data such as wind speed, position, torque, and angle. After PLC calculations and testing, the calculated and evaluated results are transmitted to the operation terminal, allowing operators to control and operate the truss 1's deployment, retraction, lifting, and lowering processes through the hydraulic system 10. The audible and visual alarm system 11 provides overload warnings.

[0020] The present invention is suitable for the rapid deployment, recovery, lifting, and lowering of Antarctic krill trusses in different operating water depths, different sea areas, and different fishing conditions. The operation process and implementation method are as follows: When truss 1 receives the deployment command, intelligent control system 5 first assesses whether the current environment is suitable for deployment. If so, thrust cylinder 2 activates to push truss body 12 outboard. Simultaneously, hydraulic system 10 begins adjusting pressure, allowing truss body 12 to deploy from base 14 to a predetermined angle. Then, under the pull of wire rope winch 3 and wire rope 4, truss 1 is gradually deployed outward until fully deployed. The pitch angle of truss 1 is also adjusted by wire rope winch 3 and wire rope 4. Rotation of rotor 13 allows truss 1 to be rapidly adjusted in three directions to determine the optimal fishing posture and deployment area.

[0021] The specific control steps of the truss retraction and extension system are as follows: (1) The wire rope on the wire rope winch is connected to the fixing device on the truss; (2) Start the intelligent control system; (3) Open the thrust cylinder device and expand the truss to a certain angle; (4) The truss reaches the designated position under the pulling action of the wire rope winch; (5) Under the pulling action of the auxiliary winch, the intelligent control system adjusts the horizontal rotating body according to the actual required horizontal angle of the truss; (6) The horizontal adjustment and fixing of the truss are completed; (7) The intelligent control system adjusts the vertical rotating body according to the actual vertical angle required by the truss; (8) The vertical adjustment and fixing of the truss are completed; (9) Start the self-retracting system and use the wire rope winch to pull the truss back; (10) After the recovery is completed, the sound and light alarm system is activated; (11) Shut down the entire system.

[0022] In the above process, the sensor network including the wind speed sensor 6, the position sensor 7, the torque sensor 8, and the angle sensor 9 continuously feeds back data to the intelligent control system through the sensor network so that necessary adjustments can be made in a timely manner.

[0023] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
