Description

Technical Field

[0001] This invention relates to the field of underwater towing technology, specifically to a tow cable guide vane with an adjustable airfoil in real time. Background Technology

[0002] Currently, an increasing number of underwater towing systems are adding guide vanes to their towlines to meet system resistance, vibration, and depth requirements. The guide vanes currently in use mainly consist of fixed-airfoil blades, trailing plates, connecting plates, and fasteners. During towing, the guide vanes are subjected to the combined effects of fluid forces and towline friction, causing the cross-section of the guide vane to form an angle with the towing direction. This angle causes the entire towline to unfold in a horizontal plane perpendicular to the towing direction, affecting the efficiency and accuracy of the towing operation.

[0003] As human exploration of the ocean continues to advance, the underwater towing field faces increasingly deeper waters and higher requirements for detection accuracy, demanding greater precision and efficiency from towing operations. Therefore, there is an urgent need for a tow cable guide vane capable of real-time airfoil adjustment. Summary of the Invention

[0016] Preferably, the winglet I and the winglet II are hinged together by a connecting shaft.

[0017] Preferably, the top of the wing I has a hinge support I that is hinged to the wing II. The hinge support I has threaded holes at both ends for fixing the connecting shaft. The hinge support I has lower arc surfaces on both sides for installing the telescopic bladder. The surface of the lower arc surfaces is polished smooth and burr-free to prevent the surface from being scratched when the telescopic bladder expands.

[0021] Beneficial effects:

This structure is small in size, light in weight, low in cost, and easy to install and disassemble.

[0023] (2) The structure of pipe II in this invention is flexible, which facilitates the connection between each pipe II and the corresponding expansion bladder and pipe I, and also helps to effectively store a large number of scattered connecting pipes together.

[0024] (3) In this invention, the two telescopic bladders and the two pipelines I are arranged symmetrically, which is conducive to the precise adjustment of the volume of the two telescopic bladders, thereby accurately controlling the directional rotation of the blade I around the blade II, so as to realize the function of real-time adjustment of the airfoil shape.

[0025] (4) The use of tow cable in this invention is beneficial for multiple guide plates to be used in a row to transmit tension or thrust, and also beneficial for single use to be connected with other floating bodies to transmit tension or thrust.

[0026] (5) The hinge support I and the lower arc surface designed at the top of the wing I in this invention, and the hinge support II and the upper arc surface designed at the bottom of the wing II, and the wing I and the wing II cooperate through the hinge support I, hinge support II, upper arc surface and lower arc surface, so that the telescopic bladder is reasonably assembled between the wing I and the wing II, which is conducive to ensuring that the wing I rotates relative to the wing II.

[0027] (6) The connection interface on the blade II in this invention can realize the connection between adjacent tow cable guide blades; when multiple guide blades are used in a row along the wingspan direction, the chamfers on both sides of the tow blade can effectively prevent the stacking interference of adjacent guide blades.

Detailed Implementation

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] This embodiment provides a tow cable guide vane with real-time adjustable airfoil. The guide vane adopts a segmented design, which can adjust the airfoil of the tow cable guide vane in real time. This structure has wide applicability and is applicable to both pneumatic and hydraulic drives. It can be used as a single piece or in a row. The structure is small in size, light in weight, low in cost, and easy to install and disassemble.

[0036] like Figure 1 As shown, the tow cable guide plate includes: wing I1, airbag 2, honeycomb plate 3, connecting shaft 4, connecting pipe I5, quick connector 6, air pipe 7, wing II 8, connecting pipe II 9, and tow plate 10.

[0037] Wing I1 and wing II 8 are hinged together via connecting shaft 4. Two symmetrical arc-shaped spaces along the thickness direction are reserved between wing I1 and wing II 8. Each arc-shaped space extends along the wingspan direction, and an airbag 2 can be installed in each arc-shaped space. The airbag 2 can inflate or deflate to provide driving force for wing I1, causing wing I1 to rotate around wing II 8 along with connecting shaft 4. Specifically, when... Figure 1 When the pressure of the left airbag 2 is greater than the pressure of the right airbag 2, the wing I1 deflects to the right; conversely, when the pressure of the right airbag 2 is greater than the pressure of the left airbag 2, the wing I1 deflects to the right. Figure 1 When the pressure of the left airbag 2 is less than the pressure of the right airbag 2, the wing I1 should deflect to the left.

[0038] Each of the two airbags 2 is covered by a honeycomb plate 3. The two honeycomb plates 3 correspond to the two airbags 2 and are also symmetrically arranged along the thickness direction of the whole formed by the wing I1 and the wing II 8, and both are symmetrical and stable along the whole formed by the wing I1 and the wing II 8.

[0039] In this embodiment, as Figure 5 As shown, the trailing plate 10 is an arc-shaped curved plate structure that can cover the air pipe 7 and the towing cable 11 and rotate around the towing cable 11 and the air pipe 7; wherein, the extension direction of the trailing plate 10 is consistent with the wingspan direction of the winglet II 8.

[0040] In this embodiment, as Figure 4 As shown, the U-shaped groove opening of the winglet II8 has a threaded hole 18 for connection with the drag pad 10, as... Figure 5 As shown, the drag pad 10 has a countersunk hole 20 for connecting with the wing plate II8. Fasteners pass through the countersunk hole 20 on the drag pad 10 and the threaded hole 18 on the wing plate II8 in sequence to connect the drag pad 10 and the wing plate II8 into one unit.

[0041] In this embodiment, as Figure 3 As shown, the top of the wing I1 has a hinge support I12 for connecting the wing II 8 and the connecting shaft 4. The hinge support I12 has threaded holes at both ends for fixing the connecting shaft 4. The two sides of the hinge support I12 have lower arc surfaces 13 for installing the airbag 2. The surface of the lower arc surface 13 is polished smooth and burr-free to prevent the surface of the airbag 2 from being scratched when it expands. The two lower arc surfaces 13 are symmetrically arranged in the thickness direction of the wing II 8.

[0042] In this embodiment, as Figure 4 As shown, one end of the wing II8 near the wing I1 has two hinge supports II15 connected to the wing I1. Each hinge support II15 is designed with a through hole for mounting the connecting shaft 4. On both sides of the hinge support II15, there are upper arc surfaces 16 for mounting the airbag 2. The surface of the upper arc surface 16 is polished smooth and burr-free to prevent the surface from being scratched when the airbag 2 expands. The two upper arc surfaces 16 are symmetrically arranged in the thickness direction of the wing I1. The lower arc surface 13 and the upper arc surface 16 on the same side form an arc-shaped space.

[0043] In this embodiment, as Figure 1 As shown, the connecting shaft 4 is a stepped shaft, with one end being a smooth round rod and the other end being a threaded rod. The end of the threaded rod first passes through the through hole of the hinge support II15 on the wing II8, and then screws into the threaded hole of the hinge support I12 on the wing I1 to fix the wing II8 and the wing I1.

[0044] In this embodiment, the airbag 2 can also be replaced with other telescopic airbags, such as an oil-filled airbag. When using an oil-filled airbag, the way to control the airfoil of the tow cable guide vane is the oil-filling method. If it is changed to the oil-filling method, the air pipe 7 is changed to an oil-filling pipeline, that is, the pneumatic drive is changed to the hydraulic drive.

[0045] The assembly process of the tow cable guide plate is as follows:

[0046] Step 1: Place the two airbags 2 in the center on the two lower arc surfaces 13 of the wing I1;

[0047] Step 2: Place winglet II8 above winglet I1, align the through hole of hinge support II15 with the threaded hole of hinge support I12 on winglet I1, and then, from both ends of the two connecting shafts 4, pass through the through hole of hinge support II15 and screw them into the threaded hole of hinge support I12 to connect winglet II8 and winglet I1 into one unit; finally, pass the connecting pipe 15 out of the groove 14 in the middle of winglet II8 and vulcanize it into one unit with airbag 2; complete the installation of winglet II8, winglet I1 and airbag 2. After installation, winglet I1 must be able to rotate around winglet II8.

[0048] Step 3: Take two honeycomb panels 3, keep them aligned with the edges of vane II 8 and vane I1, and bond each honeycomb panel 3 to vane I1 and vane II 8 to form a streamlined and continuous guide vane substrate.

[0049] Step 4: Insert the two connecting tubes I5 into the quick connector 6;

[0050] Step 5: Take two air tubes 7, select the corresponding positions to connect tubes II 9 respectively, and insert the two connecting tubes II 9 into the quick connector 6;

[0051] Step 6: Take the drag pad 10 and the drag cable 11, align the open side of the drag pad 10 with the drag cable 11 and the air pipe 7 assembly, align the countersunk hole 20 of the drag pad 10 with the threaded hole 18 at the upper end of the wing II 8, and fix the drag pad 10 to the wing II 8 with fasteners.

[0052] Step 7: Use clamps to bind the two air hoses 7 to the tow cable 11; if the air hoses 7 and the tow cable 11 have been pre-bound, this step can be omitted;

[0053] Step 8: Inject gas into the corresponding airbags 2 simultaneously through two air tubes 7. Stop injecting when the airbags 2 on both sides inflate to the preset size. When gas is injected into the left airbag 2 and gas is extracted from the right airbag 2, the wing I1 deflects to the right. Conversely, when gas is extracted from the left airbag 2 and gas is injected into the right airbag 2, the wing I1 deflects to the left. Thus, by changing the volume between the two airbags 2, the wing I1 is controlled to rotate directionally around the wing II 8. The honeycomb panels 3 on both sides then undergo flexible deformation, adjusting the airfoil of the tow cable guide vane in real time. At this point, the installation of the tow cable guide vane with real-time adjustable airfoil is completed.

[0054] In this embodiment, the guide vane can be used individually or multiple guide vanes can be arranged in a row along the wingspan direction and connected to the tow cable 11. When used in a row, the airbag 2 of the guide vane that needs to control the airfoil can be connected to the air pipe 7 as needed; for guide vanes that do not need to control the airfoil, the connecting pipe II 9 connected to the corresponding airbag 2 can be blocked; when multiple guide vanes are used in a row, one air pipe 7 can simultaneously control the inflation or deflation of the airbags 2 of multiple guide vanes.

[0055] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
