Technical Field
[0001] This invention relates to the field of marine fishing systems technology, specifically to an intelligent deployment and self-cleaning system and method for Antarctic krill fishing trusses. Background Technology
[0002] Antarctic krill, as one of the largest biological populations on Earth, has become a valuable marine resource that countries around the world are vying to develop and utilize. To effectively capture this abundant resource, fishing vessels have become indispensable harvesting tools, and fishing methods have undergone a significant evolution from traditional trawls to modern truss trawls with continuous pump suction technology. In this advanced fishing system, the truss plays a crucial role; it not only bears the enormous tensile force of the trawl net but also flexibly adapts to various changes in the vessel's attitude and precisely adjusts the distance between the net and the vessel, thereby ensuring the efficiency and stability of the fishing operation.
[0003] However, existing truss devices and their supporting systems present a pressing problem: during the deployment and retraction of the truss, if it encounters foreign objects or unknown obstacles, the system often fails to provide timely feedback, making it difficult for operators to react promptly. If operation is continued under these circumstances, it could cause serious damage to the truss structure, thereby affecting the smooth progress of the entire fishing operation and even leading to safety accidents.
[0004] Based on this, the present invention proposes a novel intelligent deployment and self-cleaning system and method for Antarctic krill fishing trusses. Summary of the Invention

[0020] Further, the identification module comprises a camera; the camera is used for capturing image information of the front end of the truss structure.

Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0043] In the description of the embodiments of the present application, it should be noted that unless specifically defined and limited, the terms "connected", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection, it can be mechanical connection, or electrical connection, it can be direct connection, or indirect connection through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0044] There is a technical problem in the prior art that during the folding and unfolding of the truss, foreign matter or unknown obstacles are encountered, and relevant information cannot be fed back in time, making it difficult for the operator to make timely response. In view of this technical problem, the present application proposes an innovative solution - a South Polar krill fishing truss intelligent folding and unfolding and self-cleaning system and method.
[0045] The embodiments of the present application will be further described in detail below with the help of the accompanying drawings Figures 1 to 4 and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.
[0046] Example 1
[0047] As Figure 1 shown, the South Polar krill fishing truss intelligent folding and unfolding and self-cleaning system provided by the embodiments of the present application comprises: a truss structure, an identification module 7, a cleaning module 8, a monitoring module 10 and a control module 9.
[0048] The truss structure can be connected to the ship end in multiple directions for towing underwater netting.
[0049] Specifically, as Figure 2 and Figure 3 shown, the truss structure comprises: a truss 1, a cable-stayed cable group 2, a truss rotating shaft 3, a truss pushing device 4, a front end fixing device 5, a rear end fixing device 6 and a top end fixing device.
[0050] The truss 1 is used to suspend a trawl car to make the trawl steel wire rope pass through the trawl car to tow underwater netting.
[0051] One end of the truss 1 is rotatably connected to the ship end through the truss rotating shaft 3; the truss pushing device 4 is used to push the truss 1 to change from a vertical state to a horizontal unfolded state.
[0052] The outer end of the truss 1 is rotatably connected to the ship end through the cable-stayed cable group 2 and the front end fixing device 5, the rear end fixing device 6 and the top end fixing device; under the action of the cable-stayed cable group 2, the front end fixing device 5, the rear end fixing device 6 and the top end fixing device, the outer end of the truss 1 can be realized in three-dimensional direction rotation through three-point fixing.
[0053] In one specific example, the cable group 2 includes a front cable, a rear cable and a top cable.
[0054] The front cable, the rear cable and the top cable are connected to the outer end of the truss 1 at an angle of 45°, respectively, to decompose the trawl tension under the outer end of the truss 1 in three directions in which the cables extend.
[0055] By adjusting the length of each working rope, the desired truss deployment position can be achieved.
[0056] The truss rotation shaft 3 is a cross-shaped bidirectional rotation shaft, and the truss 1 can rotate in multiple directions around the cross-shaped bidirectional rotation shaft to make the truss 1 rotate horizontally and / or vertically.
[0057] Specifically, the truss rotation shaft 3 includes a horizontal rotation shaft and a vertical rotation shaft, and the horizontal rotation shaft and the vertical rotation shaft are arranged in a cross shape.
[0058] In an optional embodiment, the truss pushing device 4 includes a ball head hydraulic pushing cylinder.
[0059] The pushing part of the truss pushing device 4 is in spherical contact with the truss 1, and under the action of the ball head hydraulic pushing cylinder, the truss 1 can be gradually unfolded and pulled apart to the target angle under the traction of the front end fixing device 5.
[0060] Using the principle of moment balance, the moment generated between the cylinder pushing point of the ball head hydraulic pushing cylinder and the horizontal rotation shaft 31 is defined as M1, and the static friction moment M2 of the truss 1 at the horizontal rotation shaft is defined. In the case of M1>M2, the truss 1 can be unfolded horizontally under the pushing force.
[0061] The truss rotation shaft identification module is installed at the front end of the truss rotation shaft truss structure and is used to identify obstacles.
[0062] Specifically, the truss rotation shaft identification module includes a camera, and the truss rotation shaft camera is used to capture image information of the front end of the truss rotation shaft truss structure.
[0063] When the truss rotation shaft identification module identifies an obstacle, the truss rotation shaft identification module feeds back initial identification information to the control module.
[0064] The truss rotation shaft control module controls the truss rotation shaft truss structure to stop the deployment action and starts the cleaning module according to the initial identification information of the truss rotation shaft, and the truss rotation shaft cleaning module removes the obstacle through the back-and-forth movement of the front end cleaning device.
[0065] After the truss rotation axis identification module identifies the cleaning completion, it feeds back the cleaning identification information to the truss rotation axis control module. The truss rotation axis control module controls the start of the cleaning action of the truss rotation axis cleaning module and the start of the truss structure retraction and extension actions based on the truss rotation axis cleaning identification information until the fishing and retrieval are completed.
[0066] The truss rotation axis monitoring module is used to monitor the length of the working ropes of the truss rotation axis truss structure.
[0067] The truss rotation axis cleaning module, truss rotation axis identification module, and truss rotation axis monitoring module are all electrically connected to the truss rotation axis control module.
[0068] The truss rotation axis control module is used to control the precise positioning of the truss structure based on the monitoring information from the truss rotation axis monitoring module, and to control the retraction and extension actions of the truss structure and the cleaning actions of the truss rotation axis cleaning module based on the identification information from the truss rotation axis identification module.
[0069] Based on the above embodiments, the intelligent deployment and self-cleaning system for Antarctic krill fishing trusses further includes a monitoring module.
[0070] The truss rotation axis monitoring module is used to monitor the recognition images of the truss rotation axis identification module in real time, so as to provide feedback on the working status of the truss structure and the truss rotation axis cleaning module.
[0071] Specifically, the truss rotation axis monitoring module includes an audible and visual alarm device, which is used to issue an audible and visual alarm when abnormalities are detected in the truss structure and the cleaning module of the truss rotation axis.
[0072] Example 2
[0073] like Figure 4 As shown in the figure, the intelligent deployment and self-cleaning method for Antarctic krill fishing trusses provided in this embodiment of the invention includes the following steps:
[0074] S1. Based on the target horizontal and vertical angles, the control module controls the truss structure to adjust at multiple angles in three dimensions until the truss and underwater net are in the target state.
[0075] S2. The recognition module identifies obstacles and transmits the recognition information to the control module.
[0076] S3. The truss rotation axis control module controls the extension and retraction of the truss structure and the cleaning action of the truss rotation axis cleaning module based on the identification information of the truss rotation axis identification module.
[0077] Specifically, when the identification module identifies the obstacle, the truss rotating shaft control module controls the truss rotating shaft structure to stop the action of winding and unwinding and starts the cleaning module according to the identification information of the truss rotating shaft identification module.
[0078] In summary, the Antarctic krill fishing truss intelligent winding and self-cleaning system and method provided by the embodiment of the application has the following advantages:
[0079] (1) The Antarctic krill fishing truss intelligent winding and self-cleaning system provided by the application can improve the operation efficiency and reduce the risk and uncertainty caused by human operation by monitoring the winding and unwinding length of each working rope, feeding the data to the control module for processing, and positioning accurately with the expected truss winding position as the target.
[0080] (2) The Antarctic krill fishing truss intelligent winding and self-cleaning system provided by the application can identify the abnormal state of the truss winding by setting the identification module.
[0081] (3) The Antarctic krill fishing truss intelligent winding and self-cleaning system provided by the application can automatically remove foreign matter in the truss winding process by setting the control module to real-time process and feedback the state of the truss work and real-time control the cleaning module, thereby ensuring the safety of the truss winding.
[0082] The system and method can monitor the state of the truss in the winding process in real time and quickly feedback to the operator when encountering foreign matter, so that appropriate measures can be taken in time. At the same time, the self-cleaning mechanism is also integrated, which effectively reduces the risk of foreign matter attachment and blockage, further improving the reliability and durability of the system. This innovative design not only ensures the safety and efficiency of the fishing operation, but also provides strong technical support for the sustainable utilization of Antarctic krill resources.
