Abstract
Description
Technical Field
[0001] This utility model relates to the field of tuna purse seine fishing vessels, and in particular to a storage net wave-blocking structure and a purse seine fishing vessel. Background Technology
[0002] Tuna purse seine fishing vessels typically have a net storage platform with bollards at the stern. For example... Figure 1 As shown, in existing technology, the storage net sinking platform 30 is arranged on the stern deck 20, and its platform 33 is installed as a sinking structure that intrudes into the ship's compartment 5. Because this sinking platform is close to sea level 4, its height is typically only 1.8 meters. To ensure operational safety, the existing solution adds a first baffle 31 and a second baffle 32 to form a groove structure. However, this closed design obstructs drainage channels. Although drainage outlets are pre-installed within the sinking platform, the water is difficult to drain effectively due to its proximity to sea level and the intense swells. Workers must operate the nets in the accumulated water for extended periods, increasing the risk of slipping and reducing operational efficiency. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a wave-blocking structure for seed storage nets and a purse seine fishing vessel, so as to improve the safety factor of personnel operations and simultaneously improve the drainage performance of the platform.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A net storage and wave-blocking structure includes a semi-open net storage platform located at the junction of the main deck and the stern deck, facing the stern, wherein the net storage platform is at the same plane height as the main deck.
[0006] Furthermore, the storage platform has wave-breaking plates for forming a barrier between it and the main deck.
[0007] Furthermore, at least one drainage outlet communicating with the side of the main deck is provided on the wave shield.
[0008] Furthermore, the wave deflector includes a vertical baffle extending upward along the main deck to form a wave barrier and a horizontal baffle connecting the vertical baffle and extending towards the stern deck, and forms a concave cavity extending laterally towards the side on the side facing the stern deck, constituting the semi-open structure.
[0009] Furthermore, the drain outlet is located on the vertical baffle.
[0010] Furthermore, cable bollards are installed within the concave cavity.
[0011] Furthermore, the horizontal baffle is supported and fixed by a number of support rods.
[0012] Furthermore, the vertical baffle can extend vertically upwards or extend obliquely towards the stern.
[0013] Purse seine fishing vessel, including any of the above-mentioned net storage and wave-blocking structures.
[0014] The beneficial effects of this utility model are as follows:
[0015] The present invention provides a net storage and wave-blocking structure and a purse seine fishing vessel. Firstly, it increases the height of the net storage platform, allowing operators to work as far away from the sea surface as possible to avoid wave surges and improve the safety factor of the operation. Secondly, the semi-open platform structure effectively prevents water accumulation in the net storage platform, and at the same time, it is equipped with drainage outlets connected to the main deck to ensure the drainage performance of the rear side of the main deck.

The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0022] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features.

[0026] Figure 2 and Figure 3 A wave-blocking structure for a storage net is shown, including a wave-blocking plate 11 disposed at the stern of the main deck 10. The wave-blocking plate 11 has a vertically extending baffle 11a and a horizontal baffle 11b connecting the vertical baffle 11b and extending toward the stern deck 20, forming a recess 13 at the stern of the main deck 10 that extends laterally toward both sides. At least one bollard 34a for securing cables is disposed within the recess 13, thereby forming a storage net platform 30a.
[0027] In some embodiments, bollards 34a are positioned at both ends of the cavity 13 near the hull side.
[0028] A drain outlet 12 is provided in the middle of the vertical baffle 11a. The drain outlet 12 connects the cavity 13 to the main deck 10 of the stern 1, allowing seawater on the main deck 10 to be discharged through the drain outlet 12 and the storage net platform 30a. The horizontal baffle 11b extends rearward and is supported and fixed by several support rods 11c at the bottom.
[0029] In some embodiments, the vertical baffle 11a may be configured to extend vertically upward or to extend obliquely toward the stern in a more hydrodynamic manner to facilitate the discharge of seawater from above.
[0030] The stern ramp deck 20 is inclined and consists of a central ramp 23 and two side ramps 22. The central ramp 23 is used to place cable boats (not shown) and is coaxial with the centerline of the hull. Steps 21 for walking are provided on the side ramps 22.
[0031] This utility model provides an optimized wave-blocking structure for net storage, the core of which lies in the wave-blocking plate 11 installed at the stern of the main deck 10. The wave-blocking plate 11 consists of a vertical baffle 11a and a horizontal baffle 11b: the vertical baffle 11a extends upward along the main deck 10 to form a wave barrier; the horizontal baffle 11b connects to the vertical baffle 11a and extends towards the stern ramp deck 20, together forming a concave cavity 13 extending laterally towards the hull side. This semi-open concave cavity design facing the stern replaces the original closed groove. At least one bollard 34a is installed within the concave cavity 13 to secure the net cables, forming a novel net storage platform 30a. Compared to the solution of creating a net storage platform 30 on the side ramp 22, the technical solution involved in this application also significantly increases the area of the mooring operation area, no longer limited to the original small groove.
[0032] Figure 4 The overall structure of the purse seine vessel is shown. The net storage platform 30a is placed at the stern 1, at the same level as the main deck 10. The upward placement of the space is beneficial to improving the steering gear room 2 at the bottom of the stern ramp deck 20. Figure 3 On the one hand, the raised storage platform 30a is at least 2.8 meters above sea level, allowing personnel to work at sea away from the sea level. Figure 3 To avoid being disturbed by waves and affecting work safety, the semi-open structure of the 30a storage platform also facilitates the discharge of surging seawater and avoids water accumulation.
