Background technology
The installation of towed cable fairing can effectively promote the serviceability of underwater towed system.For example: reduce towing cable tension force, reduce the towing cable shake, improve submergence depth and cable laying length ratio and prolong the towing cable life-span etc.For relying on airfoil lift or propeller thrust to realize that towed body carries out when water conservancy diversion is enclosed within sub aqua sport, meets flow path direction and constantly changing for the towing system of undulation under water, therefore need adopt sectional type be installed on the towing cable in the water conservancy diversion cover.The set segmented formula of water conservancy diversion is installed its folding and unfolding has been proposed requirement, because the effect of gravity, is difficult to by track adjusting wheel when water conservancy diversion is enclosed within folding and unfolding and drags wheel, makes it smoothly by track adjusting wheel with drag wheel thereby therefore need lead to the water conservancy diversion cover.The design and craft of this aspect does not see as yet that both at home and abroad relevant report is arranged at present.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of and when the folding and unfolding of water conservancy diversion cover it is rotated to an angle around towing cable, guarantees the spiral righting mechanism that is used for the sectional type towed cable fairing of towed cable fairing safety folding and unfolding.
The utility model solves the technical scheme that its technical matters adopts: this spiral righting mechanism that is used for the sectional type towed cable fairing, comprise main shaft, one side of main shaft is provided with one group of guide pillar, is socketed with the cylinder that can rotate flexibly on each guide pillar, and this group guide pillar is arranged and constituted a helix driving band; Main shaft is respectively equipped with baffle plate, bearing at the two ends of helix driving band, and steamboat is housed on the bearing, and the wheel rim place of steamboat has and can hold the annular groove that water conservancy diversion cover guide margin passes through; Also be provided with the helix press strip that is parallel to the helix driving band on the main shaft.
The effect that the utility model is useful is: the utility model is rational in infrastructure, and result of use is good, makes it smoothly by track adjusting wheel with drag wheel thereby can be easily the water conservancy diversion cover be led, and guarantees the folding and unfolding of towed cable fairing safety.This is used for the spiral righting mechanism simple installation of sectional type towed cable fairing; In the process of folding and unfolding cable, do not need manual intervention; Can guarantee the folding and unfolding safety of towed cable fairing.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
This spiral righting mechanism that is used for the sectional type towed cable fairing comprises main shaft 1, and main shaft 1 material adopts high-strength stainless steel, and main shaft 1 length is long greater than the exhibition of 6 times of water conservancy diversion covers 13.Have one group of tapped bore 1-1 of line arrangement in the shape of a spiral on the main shaft 1, tapped bore 1-1 line in the shape of a spiral arranges, and the anglec of rotation is not less than 150 degree.The hand of rotation of tapped bore 1-1 is decided on installation site and winch 12 row's cable modes.Main shaft 1 is plugged with one group of guide pillar 2 on this group tapped bore 1-1, the length of guide pillar 2 is about the chord length of water conservancy diversion cover 13.This guide pillar 2 is three sections stepped shaft, adopts high-strength stainless steel, and an end is provided with the threaded connector 2-1 that is complementary with tapped bore 1-1, and the other end is provided with defining flange 2-2; Guide pillar 2 is plugged on the main shaft 1 by its threaded connector 2-1.Be socketed with the cylinder 3 that can rotate flexibly on each guide pillar 2, this group guide pillar 2 is arranged and is constituted a helix driving band.Cylinder 3 is a thin circular cylinder, and between flange 2-2 and main shaft 1, material adopts high-strength stainless steel, adopts rolling touch with water conservancy diversion cover 13, reduces friction.Main shaft 1 is respectively equipped with baffle plate 4, bearing 5 at the two ends of helix driving band.Baffle plate 4 profiles are trapezoidal, are with circular arc slightly; Be installed in main shaft one end, material adopts high-strength stainless steel, plays guiding and location.Bearing 5 materials adopt high-strength stainless steel, and it is equipped with steamboat 6 by fastener 9, and the wheel rim place of steamboat 6 has and can hold the annular groove 6-1 that water conservancy diversion cover guide margin passes through, and material adopts high-strength stainless steel or plastics, plays guiding and location.Also be provided with the helix press strip 7 that is parallel to the helix driving band on the main shaft 1, the spacing of press strip 7 and helix driving band is slightly larger than water conservancy diversion and overlaps 13 maximum ga(u)ges, plays the role of positioning, and material is stainless reinforcing bar.Main shaft 1 is provided with the adapter plate 8 that is used to install the spiral righting mechanism that is used for the sectional type towed cable fairing, and this adapter plate 8 is a T shape flat board, and two ends have connecting bore; The installation that is used for the spiral righting mechanism of sectional type towed cable fairing connects, and concrete dimensional structure is decided on dragging wheel 10 and winch track adjusting wheel 11, and material adopts high-strength stainless steel.
