The anti-roll grooves are open on the head and tail end surfaces of the stabilizing fins, and the depths of the anti-roll grooves are different.

[0007] The depth of the anti-roll groove is first deep and then shallow from the head to the middle to form a first buffer zone, and the depth of the anti-roll groove is first deep and then shallow from the middle to the tail to form a second buffer zone.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Figure 1 A high-speed racing boat shown in the figure comprises a bottom plate 1 made of a brushed air cushion, with air bags 2 fixed on the left and right sides of the bottom plate, the head of the air bag is conical, and the head of the air bag is tilted upward and out of the water surface, and the head end of the bottom plate is tilted upward and out of the water surface together with the head of the air bag. The head end of the racing boat is sharp, which can reduce wind resistance when traveling at high speed; the part of the bottom plate that always contacts the water surface is the contact surface 3.

[0024] like Figure 3 As shown, a wave-breaking fin 4 is fixed in the middle of the contact surface 3 along the length direction, the length of the wave-breaking fin is smaller than the length of the contact surface, and the head end of the wave-breaking fin extends forward beyond the contact surface, and the head end of the wave-breaking fin is conical; the wave-breaking fin is in an upright plate shape, and the lower edge of the wave-breaking fin is in a curve shape that bends up and down, and the lower edge of the wave-breaking fin bends downward from the head end to form a downward convex portion, extends to the waist, bends upward to form a narrow portion, and then bends downward again to form a downward convex portion, and the convex portion near the tail end is wider than the convex portion near the head end.

[0025] like Figure 2 and Figure 3 As shown, stabilizing fins 5 are fixed on the contact surface and the bottom surface of the airbag. The thickness of the stabilizing fins is less than that of the wave-breaking fins. Since the water flow impact force borne by the stabilizing fins is less than that of the wave-breaking fins, the thickness of the wave-breaking fins is not required, and the overall weight of the racing boat can be reduced accordingly; there are multiple stabilizing fins, and the multiple stabilizing fins are symmetrically distributed on the left and right sides of the wave-breaking fins. The stabilizing fins on both sides are staggered backward in a stepped manner to form a V-shape with the sharp corners facing the head end. The V-formation can reduce the resistance of the racing boat during movement, which is similar to the formation of migrating geese, and can reduce the resistance during migration.

[0026] The shape of each stabilizing fin is the same as that of the wave-breaking fin, e.g. Figure 4As shown, the stabilizing fin is in the shape of an upright plate, and the lower edge of the stabilizing fin is in a curved shape that bends up and down. The lower edge of the stabilizing fin bends downward from the head end to form a first downward convex portion 51, extends to the waist and bends upward to form a narrow portion 52, and then bends downward again to form a second downward convex portion 53, and the second convex portion is wider than the first convex portion.

[0027] The materials of the wave-breaking fin and the stabilizing fin are both PVC. PVC has a small mass, which can reduce the weight of the racing boat itself and increase its agility. A reinforcement layer is fixed to the head of the wave-breaking fin to enhance the strength of the head of the wave-breaking fin to cope with the impact of air and waves.

[0028] The left and right sides of the stabilizing fin are symmetrically provided with anti-roll grooves 6, the length of which is the same as that of the stabilizing fin. The anti-roll grooves are open on both end surfaces of the head and tail of the stabilizing fin, and the depths of the anti-roll grooves are different. The depth of the anti-roll grooves is first deep and then shallow from the head to the middle to form a first buffer zone 61, and is also first deep and then shallow from the middle to the tail to form a second buffer zone 62. The depth of the first buffer zone is less than that of the second buffer zone. When the stabilizing fin enters the water, the water separates from the left and right sides of the stabilizing fin after contacting the stabilizing fin. The separated water flow impacts the stabilizing fin under the action of the water body nearby, and the impact force increases from the head to the tail. The role of the buffer zone is to increase the distance of the water flow in depth, thereby reducing the impact force of the water flow, and the greater the impact force, the deeper the depth, thereby maintaining the stability of the racing boat and preventing pitching.

[0029] Water diversion grooves are symmetrically arranged on the left and right sides of the wave-breaking fin. The length of the water diversion grooves is the same as the length of the wave-breaking fin. The water diversion grooves are opened on the head and tail end surfaces of the wave-breaking fins, and the depth of the water diversion grooves is uniform. Since the wave-breaking fin is located in the middle of the competition boat, the uniform depth of the water diversion grooves can promote the same water impact force on both sides of the wave-breaking fin, thereby helping to maintain the stability of the competition boat.

[0030] like Figure 5 , Figure 6 As shown, the upper surface of the bottom plate is provided with a raised water diversion keel 7, which extends from the middle of the bottom plate to the tail, and the height of the head end of the water diversion keel is greater than the height of the tail end of the water diversion keel; the water diversion keel is made of a brushed air cushion or PVC, and the water diversion keel diverts the water entering the competition boat. The tail end of the bottom plate is provided with a plurality of overflow holes 8 distributed along the width, and the overflow holes are connected to the overflow trough inside the bottom plate, and the outlet of the overflow trough is located on the tail end surface of the bottom plate. During the driving process of the competition boat, when the waves rush into the inside of the competition boat, due to the shape of the bottom plate, the water will flow to the tail of the competition boat, and after being diverted by the water diversion keel, it can flow out of the competition boat from the tail end of the bottom plate along the overflow holes and the overflow trough, thereby avoiding water accumulation in the boat.

[0031] The airbag is provided with a safety rope 9, a plurality of D-rings 10 for fixing the safety rope, an oar lock 11 for fixing the oar, and a handle 12, which can be used by the personnel in the boat for performing corresponding operations.

[0032] The method of using a high-speed racing boat includes the following steps:

[0033] Step 1: The wave-breaking fins and stabilizing fins are fixed on the bottom plate of the competition boat and the bottom surface of the airbags. The bottom plate of the competition boat is made of brushed air cushions. The bottom plate can be inflated through the inflation valve so that the bottom plate can float on the water. The airbags on both sides of the bottom plate are made of PVC material. After the airbags are inflated, they can float on the water.

[0034] Among them, the head of the airbag is made to be conically tilted, so that the pressure generated by the head of the airbag on the air can be increased during high-speed driving, so that the competition boat can quickly break through the air and reduce air resistance, which is beneficial to the speed increase of the competition boat; because the pointed head of the airbag is the first to contact the air, according to the interaction relationship of forces, the head of the airbag will bear a greater force, so a reinforcement layer is added to the head of the airbag to enhance the strength of the head of the airbag; thus, the hull of the competition boat includes a tilted head and a body that is always in contact with the water surface, and the bottom surface of the body that is always in contact with the water surface is the contact surface;

[0035] Step 2: The wave-breaking fin extends along the length direction of the center line of the contact surface, and the head end of the wave-breaking fin extends from the head end of the contact surface. The head end of the wave-breaking fin is conical, so that when the racing boat is driving, the wave-breaking fin can quickly insert into the water surface to divert the water surface, thereby reducing the resistance of the water flow to the boat body; multiple stabilizing fins are symmetrically distributed on the left and right sides of the wave-breaking fin, and the stabilizing fins on both sides are staggered backward in a stepped manner to form a V-shape with a sharp angle facing the head end. The shape of the wave-breaking fin and the multiple stabilizing fins is that the lower edge first bends downward from the head end to form a downward convex part, extending to The waist is bent upward to form a narrow part and then bent downward again to form a downward convex part, and the convex part near the tail end is wider than the convex part near the head end, so that the wave-breaking fin and the stabilizing fin have width, and the original surface contact friction between the bottom surface of the competition boat and the water surface is changed to line contact friction between the lower edge of the wave-breaking fin and the stabilizing fin and the water surface, which reduces the contact area and thus reduces the resistance; and the width of the wave-breaking fin and the stabilizing fin increases from shallow to deep from the degree of breaking water, and the curve of the lower edge fits the wave curve, which can reduce the hull swaying caused by waves accordingly;

[0036] Step 3: Water diversion grooves are symmetrically arranged on the left and right sides of the wave-breaking fin. The length of the water diversion grooves is the same as that of the wave-breaking fins. The water diversion grooves are opened on both end surfaces of the wave-breaking fins, and the depth of the water diversion grooves is uniform. Since the wave-breaking fins are located in the middle of the competition boat, the uniform depth of the water diversion grooves can promote the same water impact force on both sides of the wave-breaking fins, thereby helping to maintain the stability of the competition boat.

[0037] The left and right sides of the stabilizing fin are symmetrically provided with anti-roll grooves, the length of which is the same as that of the stabilizing fin, and the anti-roll grooves are open on both end surfaces of the head and tail of the stabilizing fin. The depth of the anti-roll grooves is first deep and then shallow from the head to the middle to form a first buffer zone, and is also first deep and then shallow from the middle to the tail to form a second buffer zone. The depth of the first buffer zone is less than that of the second buffer zone. When the stabilizing fin enters the water, the water separates from the left and right sides of the stabilizing fin after contacting the stabilizing fin. The separated water flow impacts the stabilizing fin under the action of the water body nearby, and the impact force increases from the head to the tail. The role of the buffer zone is to increase the distance of the water flow in depth, thereby reducing the impact force of the water flow, and the greater the impact force, the deeper the depth, so that the stability of the competition boat can be maintained to prevent pitching;

[0038] Step 4: A raised water-dividing keel is provided on the upper surface of the bottom plate, and the water-dividing keel extends from the middle of the bottom plate to the tail, and the height of the head end of the water-dividing keel is greater than the height of the tail end of the water-dividing keel; the water-dividing keel is made of a brushed air cushion or PVC, and the water-dividing keel diverts the water entering the competition boat; a plurality of overflow holes are distributed along the width of the tail end of the bottom plate, and the overflow holes are connected to the overflow trough inside the bottom plate, and the outlet of the overflow trough is located on the end surface of the tail end of the bottom plate. During the driving process of the competition boat, when the waves rush into the interior of the competition boat, they first flow through the diversion of the water-dividing keel, and then flow out of the competition boat from the tail end of the bottom plate along the overflow holes and the overflow trough, thereby avoiding water accumulation in the boat;

[0039] Step 5: The airbag is provided with a safety rope, a plurality of D-rings for fixing the safety rope, an oar lock for fixing the oar, and a handle for the people in the boat to use together in the competition boat.

[0040] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also belong to the protection scope of the present invention.
