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

A kind of fish tail jacket cartridge type streamline sheet

Technical field

The invention belongs to underwater towed system, particularly a kind of streamline sheet.

Background technology

Along with the mankind explore constantly to off-lying sea and the development of field, deep-sea ocean, the rudder plate size of under-water robot is increasing, and its load of bearing is also increasing, requires more and more stronger to the design torque of steering wheel and impact resistance.Rudder stock, when bearing large impact load, easily occurs that rudder stock ruptures, and causes robot housing to leak, and this is fatal concerning robot.In order to stop this phenomenon, need to guarantee that rudder stock is after being subject to large impact load fracture, still can ensure the water tightness of robot housing.

Summary of the invention

The object of the invention is: provide one both to have conventional sleeve formula streamline sheet low-resistance, lowly to shake, low noise characteristic, there is again the fish tail jacket cartridge type streamline sheet of good following current stability.

Technical scheme of the present invention is: a kind of fish tail jacket cartridge type streamline sheet, and it comprises: fish tail type fin, Tuo Wa, connecting strap, lining, screw;

The hollow thin slice of fish tail type fin to be section be Y type, its afterbody is fish tail type, connecting strap two ends are inserted in two pieces of fish tail type fins respectively, the knock hole B on connecting strap both sides with align with the knock hole A of two pieces of fish tail type fins respectively, insert the connection that lining realizes between two pieces of fish tail type fins, cross section is that U-shaped Tuo Wa blocks towing cable, and the knock hole C of holder watt aligns with the tapped bore of lining, two pieces of screws screw in from both sides respectively, are fixed on towing cable by fish tail jacket cartridge type streamline sheet.

Beneficial effect: the fish tail type expansion structure that the present invention is installed additional on conventional sleeve formula streamline sheet basis, increase the area of thrust surface of novel streamline sheet in lateral flow, provide larger restoring moment, the following current stability that the towing cable tool in towing process making to install this streamline sheet is good, and remain low-resistance when installing conventional formula streamline sheet, lowly to shake, low noise characteristic.

Detailed description of the invention

To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.

See accompanying drawing, a kind of fish tail jacket cartridge type streamline sheet, it comprises: fish tail type fin 1, holder watts 2, connecting strap 3, lining 4, screw 5;

Fish tail type fin 1 for section be the hollow thin slice of Y type, its afterbody is fish tail type, connecting strap 3 two ends are inserted in two pieces of fish tail type fins 1 respectively, the knock hole B8 on connecting strap 3 both sides with align with the knock hole A6 of two pieces of fish tail type fins 1 respectively, insertion lining 4 realizes the connection 1 between two pieces of fish tail type fins, cross section is that towing cable 7 is blocked in U-shaped holder watts 2, a holder watt knock hole C9 of 2 aligns with the tapped bore 10 of lining 4, two pieces of screws 5 screw in from both sides respectively, are fixed on towing cable 7 by fish tail jacket cartridge type streamline sheet.

When the fish tail angle a of fish tail type fin 1 is taken as 10 °-20 °, test results shows that the average side force suffered by it reduces 60-75% compared with the average side force of conventional sleeve formula streamline sheet, this illustrates that fish tail jacket cartridge type streamline sheet is better compared to conventional sleeve formula streamline sheet following current stability, and the towing cable having installed fish tail jacket cartridge type streamline sheet additional more not easily lateral deviation occurs.Correlation data is: install conventional sleeve formula streamline sheet towing cable 360m additional, during towing speed 8kn, and towing cable range of slip angles ± 19.1 °; Install fish tail jacket cartridge type streamline sheet towing cable 360m additional, during towing speed 8kn, towing cable range of slip angles ± 2.34 °.

In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
