Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] Referring to the accompanying drawings, a fishtail-type sleeve-type streamline piece includes: fishtail-shaped fins 1, brackets 2, connecting pieces 3, bushings 4, and screws 5;

[0020] The fishtail fin 1 is a Y-shaped hollow sheet with a fishtail tail. The two ends of the connecting piece 3 are respectively inserted into two fishtail fins 1. The positioning holes B8 on both sides of the connecting piece 3 are connected with the The positioning holes A6 of the two fishtail fins 1 are aligned, and the bushing 4 is inserted to realize the connection 1 between the two fishtail fins. The positioning hole C9 is aligned with the threaded hole 10 of the bushing 4 , and two screws 5 are respectively screwed in from both sides to fix the fishtail-shaped sleeve-type streamline piece on the tow cable 7 .

[0021] When the fishtail angle a of the fishtail fin...

Abstract

The invention in particular relates to a streamline sheet, which belongs to an underwater towing system. The technical scheme of a fishtail-shaped sleeve type streamline sheet is that the fishtail-shaped sleeve type streamline sheet comprises a fishtail-shaped fin (1), a rear pad (2), a connecting sheet (3), a bushing (4) and a bolt (5). According to the invention, due to a fishtail-shaped expanding structure additionally mounted on the basis of the traditional sleeve type streamline sheet, the force bearing area of the novel streamline sheet in a lateral flow is increased and great return moment is provided so that a towing rope mounted with the streamline sheet exerts good downstream stability in the towing process and low resistance, low vibration and low noise characteristics during mounting the traditional streamline sheet are kept.

Description

technical field [0001] The invention belongs to an underwater dragging system, in particular to a streamlined sheet. Background technique [0002] With the continuous development of human exploration of the ocean to the distant sea and deep sea, the size of the rudder plate of the underwater robot is getting larger and larger, and the load it bears is also increasing, and the design torque and impact resistance of the steering gear are increasingly required. powerful. When the rudder stock is subjected to a large impact load, it is prone to breakage of the rudder stock, resulting in water leakage from the robot shell, which is fatal to the robot. In order to prevent this phenomenon, it is necessary to ensure that the watertightness of the robot shell can still be guaranteed after the rudder stock is broken by a large impact load. Contents of the invention [0003] The purpose of the present invention is to provide a fishtail-type sleeve-type streamline which not only has...
