DETAILED DESCRIPTION

[0038] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0039] With reference to Figure 1 , Figure 2 and Figure 4 , the present application provides an embodiment: a dragon boat suitable for ice surface, comprising a boat body 1, the bottom of the boat body 1 is provided with a second motor 10 at the left and right ends, through the installation of the second motor 10, the subsequent process is given power, the output end of the second motor 10 is fixedly connected with a connecting short column 16, the rear side of the connecting short column 16 is fixedly connected with a rotating column 9, one side of the rotating column 9 is rotatably connected with the boat body 1, the other side of the rotating column 9 is fixedly connected with a folding plate 4, the sides away from each other of the two connecting short columns 16 are fixedly connected with connecting ropes 8, through the installation of the connecting ropes 8, the state of the folding plate 4 is adjusted, the rear side of the connecting rope 8 is fixedly connected with the front side of the folding plate 4, the top left and right ends of the folding plate 4 are fixedly connected with square long rods 5, a plurality of springs 7 are fixedly connected with one side of the square long rod 5 at equal intervals, a rotating long rod 6 is rotatably connected with the middle part of the folding plate 4, through the installation of the rotating long rod 6, the folding plate 4 can be folded, the bottom of the boat body 1 is provided with a supporting mechanism 2 at the front and rear ends, the supporting mechanism 2 is used for supporting the boat body 1, a plurality of ice skates 11 are provided at equal intervals on the bottom of the boat body 1, a plurality of rolling bearings 15 are fixedly connected with the bottom of the folding plate 4 at equal intervals, a balance rudder 19 is installed on the top rear side of the boat body 1, fixed square plates 17 are installed on the top front and rear ends of the folding plate 4, screws 18 are threadedly connected with the top left and right ends of the fixed square plates 17, through the installation of the fixed square plates 17, when the device is not used, it can be fixed through the screws 18;

[0040] Specifically, when the dragon boat is used on the ice surface, the second motor 10 at the left and right ends of the bottom of the boat body 1 is started, the rotation of the second motor 10 drives the rotation of the connecting short column 16, and then the connecting short column 16 drives the rotation of the rotating column 9, so that the folding plate 4 is unfolded around the connecting point of the rotating column 9 and the boat body 1. During the unfolding process, the connecting rope 8 plays a role in assisting and limiting the unfolding angle and position of the folding plate 4, ensuring stable unfolding. After the folding plate 4 is unfolded, the springs 7 on the square long rods 5 at the top left and right ends play a buffering role. For example, when the ice surface is uneven or there is a jolt impact during movement, the springs 7 can buffer the impact on the boat body 1, and the rotating long rod 6 can adapt to the changes of the ice surface to a certain extent. When encountering local height differences on the ice surface, the rotating long rod 6 can rotate relative to the folding plate 4, so that the part in contact with the ice surface can better fit the ice surface, ensuring the stable movement of the dragon boat on the ice surface. Through the above process, the operation of pushing the dragon boat forward and turning on the ice surface effectively reduces the probability of instability of the dragon boat. When the athletes paddle, the pressure wave generated by the bow will form a small range of ice melting area in front, helping the boat to break through the ice and move forward. A plurality of groups of ice knives 11 contact the ice surface to generate stable support points, keeping the direction unchanged. Once it is necessary to turn, the driver can change the heading by adjusting the direction of the balance rudder 19. At this time, the inclination angle of the ice knife 11 on the corresponding side increases, generating additional lateral resistance, forcing the boat body to deflect. The small rolling bearing 15 at the bottom rotates with the movement of the boat, reducing friction loss during forward movement.

[0041] Referring to Figure 1 , Figure 3 and Figure 5 , the support mechanism 2 includes two first motors 201, which are respectively installed on the bottom front and back sides of the boat body 1. The output end of the first motor 201 is fixedly connected with a rotating circular plate 202. The installation of the first motor 201 enables the rotating circular plate 202 to rotate. The rear side of the rotating circular plate 202 is fixedly connected with a rotating short column 207. The bottom front and back sides of the boat body 1 are equally provided with a plurality of square plates 206. The adjacent sides of the two square plates 206 are both provided with a sliding groove 203. The inside left and right ends of the sliding groove 203 are both slidably connected with a sliding block 204. The sliding groove 203 facilitates the sliding of the sliding block 204. The outside of the rotating short column 207 is equally and rotatably connected with a plurality of square rods 205. One side of the square rod 205 is slidably connected with one side of the sliding block 204. The bottom of the bottom square plate 206 is equally and fixedly connected with a plurality of anti-skid balls 14.

[0042] Specifically, when the first motor 201 starts, its output end drives the rotating circular plate 202 to rotate, and then the rotating short column 207 behind the rotating circular plate 202 also rotates synchronously, and the plurality of square rods 205 connected with the rotating short column 207 at equal distances also rotate synchronously. Since one side of the square rod 205 is connected with the sliding block 204 through sliding connection, and the sliding block 204 can slide in the sliding groove 203 formed in the square plate 206, during the rotation of the square rod 205, the sliding block 204 also slides in the sliding groove 203, so as to change its position in the sliding groove 203. Through the cooperative movement of the plurality of square rods 205 and the sliding block 204, the overall shape of the supporting mechanism 2 and the contact state with the ice surface are adjusted, the stable support of the boat body 1 is realized, the supporting mode and intensity are adjusted according to the actual needs of the boat body 1 and the ice surface conditions, so as to adapt to the support needs of the boat body 1 when driving on the ice surface, and ensure that the dragon boat keeps balance and runs smoothly on the ice surface. Through the installation of the anti-skid ball 14, the stability is further improved.

[0043] Referring to Figure 1 , Figure 2 and Figure 3 , a plurality of fixed rods 13 are fixedly connected to the inside of the boat body 1 at equal distances, the front side of the fixed rod 13 is provided with the sail 12, and the inside middle part of the boat body 1 is provided with the flag 3.

[0044] Specifically, through the installation of the sail 12, the movement of the boat body 1 is facilitated, and through the installation of the flag 3, the device is easy to identify.

[0045] Working principle: when the dragon boat is used on the ice surface, the second motor 10 at the left and right ends of the bottom of the boat body 1 is started. The second motor 10 drives the connecting short column 16 to rotate, the connecting short column 16 drives the rotating column 9 to rotate, so that the folding plate 4 is unfolded around the connecting point of the rotating column 9 and the boat body 1. During the unfolding process, the connecting rope 8 plays a role in assisting and limiting the unfolding angle and position of the folding plate 4, so as to ensure the stable unfolding. After the folding plate 4 is unfolded, the springs 7 on the square long rods 5 at the top left and right ends of the folding plate 4 play a buffering role. For example, when the ice surface is uneven or there is a jolt impact during movement, the springs 7 can buffer the impact received by the boat body 1, and the rotating long rod 6 can adapt to the changes of the ice surface to a certain extent. When encountering local height difference of the ice surface, the rotating long rod 6 can rotate relative to the folding plate 4, so that the part in contact with the ice surface can better fit the ice surface, so as to ensure the stable movement of the dragon boat on the ice surface. Through the above process, the forward movement and turning operation of the dragon boat on the ice surface are realized, and the probability of instability of the dragon boat is reduced.

[0046] When the first motor 201 starts, the output end drives the rotating disc 202 to rotate, the rotating short column 207 at the back of the rotating disc 202 rotates synchronously, and the plurality of square rods 205 connected with the rotating short column 207 at the outer side also rotate synchronously. Since one side of the square rod 205 is connected with one side of the sliding block 204 in sliding mode, and the sliding block 204 slides in the sliding groove 203 of the square plate 206, in the rotating process of the square rod 205, the sliding block 204 slides in the sliding groove 203, so as to change the position of the sliding block 204 in the sliding groove 203. Through the cooperative movement of the plurality of square rods 205 and the sliding block 204, the overall shape of the supporting mechanism 2 and the contact state with the ice surface can be adjusted, so as to realize the stable support of the boat body 1. According to the actual situation of the ice surface and the demand of the boat body 1, the supporting mode and strength are changed, so as to adapt to the supporting demand of the boat body 1 when driving on the ice surface, and ensure that the dragon boat can keep balance and normally run on the ice surface.

[0047] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
