[0027] Please refer to Figures 1-5 The utility model provides a kind of racing dragon boat,

[0028] It includes a head of dragon boat 1, a boat body 2 and a tail of dragon boat 3. The boat body 2 includes a boat bottom plate 21 at the bottom and boat side plates 22 at the top of both sides. The boat body 2 has a UV type boat section 23, which includes an inner recess 231 arranged between the boat bottom plate 21 and the boat side plates 22.

[0029] As Figure 2As shown in the drawings, the boat body 2 further comprises a first inclined plate 24 connected to both sides of the boat bottom plate 21 and a second inclined plate 25 connected to both sides of the first inclined plate 24 and the bottom of the boat side plate 22; when the first inclined plate 24 and the second inclined plate 25 are located in the UV-shaped boat section 23, the second inclined plate 25 is vertically inclined at an angle greater than the first inclined plate 24 to form an inner recess 231; that is, the boat bottom plate 21 and the first inclined plate 24 form a U shape, and the second inclined plate 25 forms a V shape.

[0030] As shown in the drawings, Figures 3-4 The boat body 2 further has a U-shaped boat section 26 located at the front and rear of the UV-shaped boat section 23, and the U-shaped boat section 26 comprises an outer convex portion 261 arranged between the boat bottom plate 21 and the boat side plate 22.

[0031] When the first inclined plate 24 and the second inclined plate 25 are located in the U-shaped boat section 26, the first inclined plate 24 is vertically inclined at an angle greater than the second inclined plate 25 to form the outer convex portion 261; that is, the boat bottom plate 21 and the first inclined plate 24 and the second inclined plate 25 form a U shape.

[0032] Among them, the vertical inclination angle refers to the angle between the plate surface and the vertical plane; the smaller the angle, the closer the plate surface to the vertical, and the larger the angle, the closer the plate surface to the horizontal.

[0033] The boat bottom plate 21 is arc-shaped in both the transverse and longitudinal directions, and the longitudinal arc has a smaller arc at the front end and a larger arc at the rear end, with the lowest point located at the rear side of the boat body 2.

[0034] Among them, the boat bottom plate 21, the boat side plate 22, the first inclined plate 24 and the second inclined plate 25 can be formed by combining multiple wooden boards or by planing a whole wooden board in actual production; the wooden boards and plate pieces are fixed by nailing or iron bars.

[0035] The bottom of the boat body 2 is provided with an arc-shaped bottom bone 27, and the boat bottom plate 21 is fixed to the bottom of the bottom bone 27.

[0036] The widest part of the boat body 2 is 100-110 cm in size.

[0037] It is worth noting that, as shown in the drawings, Figure 5 The dragon boat in the embodiment further comprises crosspieces, seat plates, footboards, dragon intestines and other structures known to those skilled in the art; the specific arrangement can adopt conventional designs in the prior art.

[0038] In the embodiment, the bottom of the boat 2 is immersed in water, the athlete sits on the seat plate in the boat 2, and uses the boat paddle to slide water to make the dragon boat move forward. The water flows through the bottom of the boat 2, and part of the water flows through the inner recess 231. When the dragon boat has a tendency to tilt laterally, the inner recess 231 generates a greater pushing force on the water, and the water generates a reverse force on the boat, that is, a force that prevents the boat from tilting. At the same time, the water generates an impact on the front of the boat 2, generating an upward force on the dragon boat, making the dragon boat float up. And because the dragon boat has a high speed, it drives the water near it to flow faster, so at the tail of the dragon boat, the liquid in the middle flows fast, and the liquid on both sides flows slowly, so the liquid on both sides flows to the middle, that is, to the back of the dragon boat tail, pushing the dragon boat.

[0039] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
