Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hydrofoils, and more specifically, to an anti-sway clamping structure for hydrofoil struts on hydrofoils. Background Technology
[0002] Water transportation is an important mode of transport; however, ordinary boats suffer from high water resistance, leading to high energy consumption, and poor wave resistance, resulting in poor passenger comfort. Hydrofoils, on the other hand, have the characteristics of aircraft. The hull is detached from the water surface and is supported solely by the lift generated by the hydrofoils in the water, allowing for stable movement on the water with low resistance and low energy consumption.
[0003] Hydrofoils and their struts are the main load-bearing and force-transmitting components. For example, a T-type hydrofoil transmits its lift to the hull via a strut. Typically, the strut can move up and down within a support frame, resulting in a gap between the strut and the support. This gap can easily cause the strut to wobble and vibrate during force transmission, leading to hull swaying and rocking during flight. Prolonged vibration risks reducing the hull's reliability and also decreases passenger comfort.
[0004] Based on this, we provide a hydrofoil support anti-sway clamping structure for hydrofoil boats. Utility Model Content

[0023] The following is in conjunction with the appendix Figures 1 to 4 The present invention will be described in further detail below.
[0024] It should be noted that the accompanying drawings are schematic and not to scale.

[0025] Example 1
[0026] This utility model discloses an anti-sway clamping structure for hydrofoil struts on a hydrofoil boat. (Refer to...) Figures 1 to 2 A hydrofoil support anti-sway clamping structure for a hydrofoil boat includes a support 1, a fixed bracket 2, and a clamping member; the support 1 is disposed inside the fixed bracket 2; the clamping member is disposed on the fixed bracket 2 and is used to clamp and fix the support 1.
[0027] like Figure 1 and Figure 2 As shown, the clamping components include an active clamping block 3, a driven clamping block 4, a trapezoidal lead screw 5, a floating seat 6, a floating seat connector 7, a guide shaft 1 8, a guide shaft 2 9, a driven clamping push block 10, a sliding hole seat 11, a guide shaft 3 12, and a guide shaft 4 13; the sliding hole seat 11 is fixedly connected to the fixed bracket 2, and the sliding hole seat 11 has guide holes that mate with the guide shaft 3 12 and the guide shaft 4 13, allowing the guide shaft 3 12 and the guide shaft 4 13 to move axially along the guide holes; one end of the guide shaft 3 12 and the guide shaft 4 13 is fixedly connected to the floating seat 6, and the guide shaft 3 12 and the guide shaft 4 13... A limiting part is provided at the other end of the fourth shaft 13 to limit the axial relative movement of the third guide shaft 12, the fourth guide shaft 13 and the sliding hole seat 11, and to limit the movement of the floating seat 6 away from the support column 1; the floating seat 6 is fixedly connected to the floating seat connector 7, the floating seat connector 7 is fixedly connected to one end of the first guide shaft 8 and the second guide shaft 9, and the other end of the first guide shaft 8 and the second guide shaft 9 is fixedly connected to the driven clamping push block 10. The fixed bracket 2 is provided with a guide hole that cooperates with the first guide shaft 8 and the second guide shaft 9, and the first guide shaft 8 and the second guide shaft 9 can move axially along the guide hole.
[0028] like Figure 1 and Figure 2 As shown, the driven clamping block 4 can be pushed towards the support column 1 by the driven clamping push block 10. One end of the trapezoidal screw 5 is threadedly connected to the active clamping block 3, and the other end of the trapezoidal screw 5 is rotatably connected to the floating seat 6.
[0029] Specifically, the active clamping block 3 and the driven clamping block 4 are not clamped in the initial state. When the trapezoidal screw 5 is driven to rotate externally, it can push the active clamping block 3 to move towards the support column 1. The active clamping block 3 presses against the support column 1. The trapezoidal screw 5 applies a force to the floating seat 6 in the opposite direction to the movement of the active clamping block 3, so that the floating seat 6 drives the guide shaft 1 8, guide shaft 2 9, guide shaft 3 12 and guide shaft 4 13 to move in the opposite direction to the active clamping block 3 along each guide hole. The guide shaft 1 8 and guide shaft 2 9 drive the driven clamping push block 10 to move in the opposite direction to the active clamping block 3, thereby driving the driven clamping block 4 to move in the opposite direction to the active clamping block 3, so that the two sides of the support column 1 are clamped towards each other by the active clamping block 3 and the driven clamping block 4.
[0030] This structural design eliminates the gap between the hydrofoil and the strut 1, ensuring that the strut 1 stably transmits the lift of the hydrofoil to the hull, avoiding hull swaying and rolling caused by the gap, improving wing stability and passenger comfort.
[0031] It is worth noting that when the helix angle of the trapezoidal screw 5 is less than or equal to the self-locking angle, the clamping block can be self-locked, preventing the active clamping block 3 from moving away from the support column 1. Therefore, when the external driving force of the trapezoidal screw 5 is removed, the clamping blocks on both sides (active clamping block 3 and driven clamping block 4) can still maintain the clamping force on the support column 1.
[0032] Specifically, there are at least two guide shafts: 8, 9, 12, and 13.
[0033] Example 2
[0034] This utility model discloses an anti-sway clamping structure for hydrofoil struts on a hydrofoil boat. (Refer to...) Figures 3 to 4 A hydrofoil support anti-sway clamping structure for a hydrofoil boat includes a support 1, a fixed bracket 2, and a clamping member; the support 1 is disposed inside the fixed bracket 2; the clamping member is disposed on the fixed bracket 2 and is used to clamp and fix the support 1.
[0035] like Figure 3 and Figure 4 As shown, the clamping component includes a left cavity 14 of the bracket, a left cavity piston 15, a left cavity piston 2 16, a right cavity 17, a right cavity piston 18, a right cavity piston 2 19, a cavity connecting pipe 20, and an oil inlet / outlet port 21. The left cavity 14 and the right cavity 17 of the bracket are mounted on the fixed bracket 2, and the oil inlet / outlet port 21 is connected to the cavity. The left cavity 14 and the right cavity 17 of the bracket are connected through the cavity connecting pipe 20. The left cavity piston 15 and the left cavity piston 2 16 are connected and arranged inside the left cavity 14 of the bracket, and the right cavity piston 18 and the right cavity piston 2 19 are connected and arranged inside the right cavity 17 of the bracket.
[0036] Specifically, the left cavity piston 15, left cavity piston 2 16, right cavity piston 18, and right cavity piston 2 19 are not initially clamped. When oil enters the cavity (support left cavity 14 and support right cavity 17), the pistons (left cavity piston 15, left cavity piston 2 16, right cavity piston 18, and right cavity piston 2 19) in the support left cavity 14 and support right cavity 17 are subjected to equal pressure and move towards the support column 1 until they clamp the support column 1.
[0037] It is worth noting that the piston can stop when the chamber pressure reaches a certain value, corresponding to a certain clamping force, or when the chamber oil volume reaches a certain volume, corresponding to the piston moving to a certain position.
[0038] When oil is discharged from the cavity, the left and right cavities are subjected to equal suction and move away from the support column 1, and the support column is released from the clamping state.
[0039] This structural design eliminates the gap between the hydrofoil and the strut 1, ensuring that the strut 1 stably transmits the lift of the hydrofoil to the hull, avoiding hull swaying and rolling caused by the gap, improving wing stability and passenger comfort.
[0040] Specifically, the left cavity 14 and the right cavity 17 of the bracket are integrally formed with the fixed bracket 2.
[0041] Specifically, the left cavity 14 and the right cavity 17 of the bracket are detachably connected to the fixed bracket 2.
[0042] Specifically, there are at least two left cavity pistons 15, 16, 18, and 19.
