Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing parade floats, and particularly to a paddle drive structure for land parade floats. Background Art

[0002] A parade float is a special vehicle used in theme parks, tourist attractions, urban tourism festivals, military parades, etc. It showcases various local customs and cultural characteristics of technological development and other themes through rich float styling elements, and is deeply favored by tourists. It is also a good way of cultural publicity. Traditional floats are basically modified on a truck chassis or the exterior of a truck with static decorative shapes. Except for a few human or animal-shaped ones with dynamic modes, other styling decorative elements are mainly static, lacking some dynamic effects.

[0003] The overall structure of a parade float must use lightweight materials for easy lifting or transportation by personnel. To change the bottom of the float to a dynamic paddle effect, if manual operation is used to swing the paddle of the parade float, it will greatly increase the labor intensity of the personnel. If a servo reduction motor is used to drive it, the transmission chain is too long, the structure is relatively complex, and it will also increase the overall weight of the float. Summary of the Invention

[0004] The purpose of the present invention is to provide a paddle drive structure for land parade floats to solve the problems encountered in the above background art.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A paddle drive structure for land parade floats includes a first drive box and paddles. There are two rows of the paddles on the float, and multiple paddles are provided in each row. An inner paddle arm is provided at the hand-held end of the paddle; a driving device is provided at the input end of the first drive box, and both output ends of the first drive box are respectively connected to a second drive box through a first transmission rotating shaft. The output end of the second drive box is connected to a second transmission rotating shaft, and cams are sleeved and fixed on the second transmission rotating shaft according to the number of the paddles. The cams are rotatably connected to the inner paddle arms.

[0007] In the above solution, the paddles are installed on both sides of the float through bearing seats, and a support rod for connecting all the paddles in series is provided inside the bearing seats. The support rod is rotatably connected to the paddles.

[0008] Further, a roller is installed at the top of the outer end of the inner paddle arm, and the top of the roller is rotatably connected to the cam.

[0009] In the above solution, it further includes paddle wheels. There are two paddle wheels, which are respectively installed at one end of the bottom of the decorated boat. A third transmission rotating shaft is connected between the two paddle wheels. A third drive box is installed on the third transmission rotating shaft. The third drive box is in transmission connection with one end of any one of the second transmission rotating shafts through a fourth transmission rotating shaft.

[0010] Furthermore, the first drive box, the second drive box, and the third drive box are respectively gear transmission boxes, and the drive device is a rechargeable electric drill with adjustable speed.

[0011] Furthermore, the center points of the cams are different at the positions of each inner paddle arm, and there is a certain regular angular spacing.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: Driven by the existing drive device, the first drive box drives the oars on both sides to swing up and down through the cams. Its structure is simple and can achieve the effect of the oars of the decorated boat swinging up and down. In addition, when the cams rotate on the second transmission rotating shaft at certain positions, a dynamic swinging effect of waves can be formed. And when two paddle wheels are further in transmission connection at the end of the second transmission rotating shaft, the dynamic swinging effect of the cruising decorated boat is further enhanced, meeting the requirements of the prior art.

Specific implementation manner

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the relevant components of the present invention.

[0024] According to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various replaceable structural forms and implementation manners. Therefore, the following specific implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0025] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Embodiment 1, as Figures 1 to 7 shown, a paddle transmission structure of an onshore cruise flower boat includes a first drive box 1 and an oar 2. There are two rows of oars 2 on the flower boat, and multiple oars 2 are provided in each row. An inner oar arm 22 is provided at the hand-held end of the oar 2. The inner oar arm 22 is located inside the flower boat. By swinging the oar 2, the oar blade swings, thereby forming a dynamic effect.

[0027] A drive device 15 is provided at the input end of the first drive box 1. The first drive box 1 is a gear transmission box. It has an input shaft and two output shafts for transmitting torque in a straight line direction. Please refer to Figure 4 , the drive device 15 is a rechargeable electric drill with adjustable speed. Its speed is adjustable according to the swinging speed of the oar 2, and it can be set to rotate forward and backward. During installation, only an installation frame needs to be added to fix the handle part of the electric drill. The two output ends on both sides of the first drive box 1 are respectively connected to a second drive box 12 through a first transmission rotating shaft 11. The first transmission rotating shaft 11 is made of round steel bar. The second drive box 12 is also a gear transmission box. The difference between it and the first drive box 1 is that it has an input end and an output end for being installed at the side end of the flower boat to change the output torque in a right angle direction.

[0028] The output end of the second drive box 12 is connected to a second transmission rotating shaft 13. Fixedly sleeved on the second transmission rotating shaft 13 according to the number of oars 2 are cams 14. The cams 14 are rotatably connected to the inner oar arms 22. Under the rotation of the cams 14, the oars 2 are driven to float up and down, thereby forming a dynamic effect of swinging up and down.

[0029] Specifically, rollers 24 can be installed at the top of the outer end of the inner oar arms 22. The tops of the rollers 24 are rotatably connected to the cams 14, making the relative rotation between the two more flexible and stable, so as to swing flexibly and reflect the dynamic effect.

[0030] Furthermore, the center points of the cams 14 are different at the positions of each inner oar arm 22 and have a certain regular angular spacing. Because the center points of the cams 14 are different at the positions of each inner oar arm 22, when the cams 14 rotate, from the outside of the decorated boat, the front - to - back order of the up - and - down swings of all the oars 2 is also inconsistent. When the center points of the cams 14 are the same at the positions of each inner oar arm 22, from the outside, all the oars 2 can swing up and down simultaneously and synchronously. When the center points of the cams 14 are different at the positions of each inner oar arm 22, the up - and - down swings of each oar 2 are not unified. When the cams 14 are set with a certain regular angular spacing, when they work, from the outside, all the oars 2 can swing up and down according to a certain rule simultaneously, forming a wavy swing effect. In this way, when the decorated boat is cruising, the dynamic aesthetic feeling given to people is better.

[0031] As a preferred solution, please refer to Figure 8 , the oars 2 are installed on both sides of the decorated boat through bearing seats 23. Inside the bearing seats 23 are support rods 21 that connect all the oars 2 in series. The support rods 21 are rotatably connected to the oars 2 to facilitate the formation of a support structure for swinging up and down. To improve the stability of the oars 2 during swinging, self - aligning bearings are installed inside the bearing seats 23. The bearing seats 23 are installed not only at the connection between the oars 2 and the outer wall of the decorated boat, but also at both ends of all the transmission rotating shafts to automatically adjust the axis of the transmission for the transmission rotating shafts.

[0032] Embodiment 2, based on Embodiment 1, a paddle drive structure of a land - cruising decorated boat further includes paddle wheels 3. There are two paddle wheels 3, and they are respectively installed at one end of the bottom of the decorated boat. During the rotation of the paddle wheels 3, due to their large volume, when they rotate on both sides of the decorated boat, they can better give the audience a visual dynamic feeling, with stronger visual attraction and better aesthetic property.

[0033] A third transmission rotating shaft 32 is connected between two paddle wheels 3. A third drive box 31 is installed on the third transmission rotating shaft 32. The third drive box 31 is also a gear transmission box, and its structure is similar to that of the first drive box 1. The third drive box 31 is drivingly connected to one end of any second transmission rotating shaft 13 through a fourth transmission rotating shaft 33, so as to transmit the driving torque of the second transmission rotating shaft 13 to the fourth transmission rotating shaft 33, and then drive the two paddle wheels 3 to rotate on both sides at one end of the head of the flower boat.

[0034] When the first drive box 1, the second drive box 12, and the third drive box 31 are implemented, they are all installed on the cruising flower boat and fixed by bolts, so as to stably output torque. Each drive box can be purchased externally, and the transmission inside is through bevel gears to change the torque on a straight line into the torque at a right angle.

[0035] The fourth transmission rotating shaft 33 is obliquely installed at the bottom of the flower boat through a bearing seat. A universal joint 34 is installed on the fourth transmission rotating shaft 33, so as to facilitate the adjustment of the torque output axis. When implemented, one end of the fourth transmission rotating shaft 33 is drivingly connected to one end of any second transmission rotating shaft 13, and the other end is connected to the input end of the third drive box 31. The third drive box 31 drives the third transmission rotating shaft 32 to rotate, and then drives the two paddle wheels 3 to rotate.

[0036] Please refer to Figure 6 , couplings 16 are respectively provided at both ends of the first transmission rotating shaft 11, both ends of the second transmission rotating shaft 13, both ends of the third transmission rotating shaft 32, and both ends of the fourth transmission rotating shaft 33, for adjusting the driving torque and stabilizing the transmission direction. The coupling 16 is a self-aligning coupling, with a small volume, light weight, and strong torque adjustment ability.

[0037] In summary, in the present invention, under the drive of the existing drive device 15, the first drive box 1 drives the oars 2 on both sides to swing up and down through the cam 14. Its structure is simple and can achieve the effect of the oars 2 of the flower boat swinging up and down. In addition, when the cam 14 rotates on the second transmission rotating shaft 13 at a certain position, a dynamic swinging effect of waves can be formed. And when two paddle wheels 3 are drivingly connected to the end of the second transmission rotating shaft 13, the dynamic swinging effect of the cruising flower boat is further enhanced, meeting the requirements of the existing technology.
