Description

Auxiliary struts for large ocean-going ships

technical field

The utility model belongs to the technical field of net-laying equipment, in particular to an auxiliary support rod for light-induced net-laying of a large ocean-going ship.

Background technique

Large-scale ocean-going light-lure netting boats are first developed in Zhejiang, Fujian and other provinces and cities in recent years to use lights to lure fish and catch fish. The characteristics of high efficiency, easy operation, and wide adaptability to water areas have been popularized and applied by fishermen, and they are often operated in the high seas of the North Pacific Ocean and the Indian Ocean. Among them, the net laying is mainly to hang the net mouth of the net gear under the water surface by means of two struts installed on the side of the ship at the stern of the hull, use the current to open the net gear mouth, and then use light lure to lure the pelagic fish. Enter the net gear, and then quickly retract the net mouth and lower the net to achieve the purpose of catching fish. Since the ships and net gear required for ocean-going operations are relatively large, in order to increase the catch, the gross tonnage of the ship can reach 1,000 tons. important.

Contents of the invention

The technical problem to be solved by the utility model is to provide a large-scale ocean-going ship with light-induced netting auxiliary struts, which can meet the operation requirements of large-scale ocean-going ships with light-induced netting, and has a simple and firm structure.

The technical solution adopted by the utility model to solve the technical problem is to provide a large-scale ocean-going ship light-induced coating net auxiliary struts, including three support tubes, two triangular tubes, diagonal struts and buoys, the three support tubes are triangular The distribution is arranged in parallel, and the two ends are respectively fixed by triangular tubes. Two of the three support tubes are connected and supported by diagonal braces to form a triangular inner support. The triangular inner supports are distributed at intervals along the length direction of the support tubes. The buoys are set at the bottom of the front end of the auxiliary strut.

The triangular inner supports are evenly spaced along the length direction of the support pipe.

The support pipe is a steel pipe.

The triangular tubes, the diagonal bracing rods and the supporting tubes are connected by welding.

The buoy is a closed stainless steel hollow cylinder.

Beneficial effect

The utility model has simple and firm structure, wide source of materials, and low cost. In actual use, it can well solve the problem of designing nets and poles for large ocean-going optical lure netting ships, and can meet the requirements of netting with a perimeter of more than 420m. It is used in boats and has good practical effect.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

A large-scale ocean-going ship's optical lure netting auxiliary struts include three support tubes 1, two triangular tubes 2, diagonal struts 3 and buoys 4.

The support pipe 1 is three stainless steel steel pipes of equal length, the pipe length is 35m, and the diameter is 10cm. The three support pipes 1 are arranged in parallel in a triangular distribution. It is constructed by welding three steel pipes with a diameter of 6cm.

The three support tubes 1 are welded and supported by diagonal braces 3 to form triangular inner supports. The triangular inner supports are evenly spaced along the length direction of the support tubes 1. The diagonal braces 3 are cylindrical stainless steel with a diameter of 5 cm and a length of 20 cm. . The buoy 4 is installed at the bottom of the front end of the auxiliary strut. The buoy 4 is a stainless steel closed hollow cylinder with a length of 2m and a diameter of 40cm. The outside of the frame of this auxiliary strut is painted with anti-rust paint.

In actual use, a strut is installed on both sides of the stern of the light lure net ship. The left and right sides of the front end of the auxiliary strut are connected to the middle of the hull through cable stays, and the ends of the auxiliary strut are connected to the stern of the hull through bolts. connected. When releasing the net, the pole is supported on the two corners of the stern, and the upper outline at both ends of the net port is tied to the front end of the pole through the ring. The auxiliary pole is located on the water surface and is almost perpendicular to the direction of the hull. The buoyancy of the pole is used to bear the weight of the net, and at the same time, the water flow is used to open the net opening to complete the laying state of the light net, and then the light is used to lure fish into the net. This type of strut can be configured on a fishing and processing integrated ship with a length of more than 50m, and can be equipped with a light cover net with a perimeter of about 420m. Fishing capacity and efficiency, suitable for fishing of pelagics such as mackerel and squid in high seas such as the North Pacific Ocean and the Indian Ocean. In actual production, it has been well promoted and used. It is especially suitable for the use of netting ships in the ocean and high seas. It can greatly increase the output of large netting ships in my country, and the net production is as high as 12 tons.
