Problems solved by technology

However, there is currently no ready-made pool that can directly simulate the actual working environment of the wave glider, especially the working environment under high sea conditions
[0004] Another option is to conduct actual sea trials on the wave glider, however, the wave glider is easily damaged in high sea conditions or after a long voyage
Since the wave glider is an unmanned device, once it is damaged, the cost of recovery is extremely high, so it is difficult to test the high sea conditions and long-term working performance of the wave glider, especially the components including the hydrodynamic fins
[0005] In addition, because the wave glider is relatively new, its theoretical research, such as force analysis, wave energy conversion efficiency, etc., still needs a large amount of actual data to improve, and sea trials have to obtain Actual data often face greater difficulties

Embodiment 1

[0037] The embodiment is basically as attached figure 1 Shown: a hydrodynamic fin testing device for a wave energy glider, comprising a stand 1 and a large water tank 11, the top of the stand 1 is rotatably connected with a reel 7, and the stand 1 in this embodiment includes an equipment platform 102 and Two support columns 101, and the equipment platform 102 is located between the two support columns 101. In this embodiment, a reinforcing rib 17 is fixedly connected between the equipment platform 102 and the two supporting columns 101 by screws, and the setting of the reinforcing rib 17 can strengthen Stability between the equipment platform 102 and the support column 101 , the equipment platform 102 and the two support columns 101 make the platform 1 a door-shaped frame structure as a whole, and the water tank 11 is located below the equipment platform 102 .

[0038] combine figure 2 As shown, the support columns 101 in this embodiment are all A-shaped structures, which ca...

Embodiment 2

[0050] like image 3 As shown, a wave energy glider hydrodynamic fin testing device differs from Embodiment 1 in that: a limit sensor 9 is installed below the equipment platform 102, and the limit switch in this embodiment adopts a proximity switch in the prior art . An electric control box 12 is installed on the stand 1, and in this embodiment, the electric control box 12 is installed on the lower part of one of the two support columns 101 by screws.

[0051] Limit sensor 9, clutch 5 and motor 2 are all electrically connected with electric control box 12, and controller etc. are installed in electric control box 12, limit sensor 9 can transmit signal to The electric control box 12 enables the electric control box 12 to control the clutch 5 to disengage.

[0052] In actual use, when the reel 7 rotates to make the rope 10 drive the underwater propeller 14 to lift upward, when the underwater propeller 14 is lifted to the water surface away from the water tank 11, when the limi...

Abstract

The invention relates to the technical field of test experiment devices, and discloses a wave energy glider hydrodynamic fin test device which comprises a rack and a water tank, the top end of the rack is rotatably connected with a winding drum, a rope is wound on the winding drum, the rope is provided with a tension sensor, a driving unit for driving the winding drum to wind or release the rope is arranged at the top end of the rack, the rope is connected with a tested object, and the tested object can move up and down in the water tank by driving the winding drum to release or wind the rope through the driving unit. According to the invention, the damage condition of each part of the underwater propeller, such as a wing panel, a connecting shaft and a bearing under a high sea condition and the fatigue and wear condition of long-time work can be simulated.

Description

technical field [0001] The invention relates to the technical field of test and experiment devices, in particular to a test device for hydrodynamic fins of a wave energy glider. Background technique [0002] The wave glider is a new type of unmanned marine vehicle that converts wave energy into forward kinetic energy. The wave glider is divided into two parts: the surface boat and the underwater propeller, which are connected by a flexible umbilical cable in the middle. The underwater propeller is equipped with hydrodynamic fins to convert wave energy into kinetic energy. Under high sea conditions, the hydrodynamic fins are under great stress and may break, and other parts such as connecting shafts and bearings may be damaged due to excessive stress. Hydrodynamic fins and other parts will also experience fatigue and wear after long-term work, so it is usually necessary to test the force of the wave glider under the waves before actual use. [0003] Although the general win...
