Description

Technical Field

[0001] The invention relates to the technical field of kayaks, and in particular to a device for preventing water from entering the hull of a kayak when it capsizes. Background Art

[0002] Kayaking is a highly competitive water sport and is mainly divided into kayaks and rowing boats according to the distribution of oars. In order to reduce water resistance, the overall appearance of a kayak is slender and shuttle-shaped, and people generally only have the lower body inside the hull. However, due to the slender structure of the kayak, it is easy to capsize in the water. The hulls of most existing kayaks have poor water-proof effects. After the hull capsizes, people are easily crushed underwater by the hull, which is dangerous. In addition, a large amount of water will enter the hull and the hull will sink when it capsizes, which increases the cost and difficulty of subsequent recovery and salvage of the hull, and further improvement is needed.

[0003] Therefore, the present invention provides a device for preventing water from entering the hull of a kayak when it capsizes, so as to solve the above-mentioned problems. Summary of the invention

[0037] Embodiment 2:

[0038] Reference Figure 1-6 As shown, the difference between the embodiment 1 and the embodiment 1 is that two sets of sliding grooves 305 are provided at both ends of the cabin 102, and sliding blocks 306 are fixedly connected at both ends of the two sets of sliding plates 304.

[0044] In this embodiment, refer to Figure 1-6 As shown, the movement of the lifting plate 202 will drive the two groups of baffles 301 to move, so that the air inlet pin 310 is separated from the air inlet of the vacuum air bag 303. The two groups of vacuum air bags 303 are inflated by air, and the cabin 202 can be filled when the cabin 202 just starts to take in water to increase the buoyancy, so as to prevent the kayak body 101 from capsizing and taking in water, and at the same time enable it to float on the water surface without sinking to the bottom.

The overall structure is simple, stable and convenient to use.

[0045] The working principle of the present invention is as follows: first, a person sits on the lifting plate 202 in the cabin 102, and uses three sets of elastic bands 203 to limit and fix the legs. When the kayak body 101 overturns and the person falls into the water, the two sets of springs 207 are no longer stressed, and the springs 207 reset to drive the lifting ring 206 to move, and the lifting ring 206 drives the connecting seat 207 to drive the lifting plate 202 to move. The movement of the lifting plate 202 separates the lower body of the person from the cabin 102, preventing the person from being pressed and trapped in the hull. At the same time, the movement of the lifting plate 202 drives the two sets of baffles 301 to move. 301 drives the air intake pin 310 to move and separate it from the air intake of the vacuum air bag 303. At this time, the vacuum air bag 303 will quickly suck in the remaining air in the cabin 102 and expand. At the same time, the sliding plate 304 is driven to move so that the cabin 102 is filled with the vacuum air bag 303, so that even if the kayak capsizes, a large amount of water will not enter the hull, and it can always float on the water surface for easy recovery. By rotating the two sets of fastening bolts 210 to separate them from the threaded holes 209, the lifting plate 202 and the baffle 301 can be removed, so that the floating assembly 3 can be reset and reused after recovery by personnel.
