Description

The paddling mechanism of a new type of recreational boat on water

technical field

The utility model relates to a small boat and a driving device for a small boat used for leisure on a lake or a calm river, more specifically, a paddling mechanism.

Background technique

At present, there are three common paddling methods of amusement park boats. First, dragon boat paddling, that is, when the person sits in the boat and holds the paddle in his hand, the entire paddle is held in the air by the human hand. Uncomfortable and prone to fatigue: The second is pedal paddling, that is, people sit on the bow or stern of the boat, step on the springboard of the oar (similar to pedaling a bicycle) to move forward, and at the same time hold the steering wheel to change the direction of the boat. Although this method is labor-saving, the fun of playing is not high; thirdly, it adopts motorized driving, which requires no effort and can be driven by simply manipulating the steering wheel. This makes people experience less than the meaning of paddling, and it is a waste of energy resources.

Utility model content

The purpose of the utility model is to provide a water stroke mechanism with simple structure, easy driving, and integrating learning and entertainment.

The utility model is realized in the following way: a new type of rowing mechanism for recreational small boats on water, including a steering wheel, the steering wheel is connected to a main shaft, the main shaft is perpendicular to the steering wheel and extends into the bottom of the boat, the main shaft is The lower end is vertically connected with a crossbar perpendicular to the water flow direction, the main shaft is located at the center of the crossbar, and the two ends of the crossbar are respectively connected with swingable paddles and baffles that limit the swing range of the paddles.

The paddle may consist of a shaft and blades.

The rotating shaft can be installed in parallel under the two ends of the cross bar, and the two ends of the cross bar are respectively connected with two upper and lower baffle plates, and the paddle swings between the upper and lower baffle plates with the rotating shaft as the center.

The rotating shaft can be vertically inserted into the two ends of the cross bar, and the two ends of the cross bar are respectively connected with two inner and outer baffles, and the paddle swings between the inner and outer two baffles with the rotating shaft as the center.

The angle at which the paddle can swing between the upper and lower baffles with the rotating shaft as the center is at most 90°.

The angle at which the paddle can swing between the inner and outer baffles with the rotating shaft as the center is at most 135°.

The rotating shaft can be obliquely inserted into the two ends of the cross bar.

The blades may be trapezoidal, arc-shaped, polygonal, etc.

Compared with the prior art, the utility model utilizes the underwater reaction force, and the driver can drive the small boat forward as long as the driver rotates the steering wheel back and forth; at the same time, the original direction control function of the steering wheel is maintained; moreover, the small The forward speed of the boat is controlled by the frequency at which the steering wheel rotates. Therefore, the utility model does not need power such as pedals, electric motors and motors, and its structure is simple and easy to use. It is also suitable for young children and mentally handicapped people to learn and exercise in shallow water areas, and the driver enjoys it.

Detailed ways

Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.

As shown in Figure 1, the utility model is made up of steering wheel 1, main shaft 2, cross bar 3, paddle and baffle plate 4. Steering wheel 1 is vertically connected with main shaft 2, and main shaft 2 extends below the bottom of the ship, and the lower end of main shaft 2 is vertically connected with cross bar 3, and cross bar 3 is in the horizontal direction, and its orientation is in the same direction as the transverse direction of the hull (that is, perpendicular to the direction of water flow). The lower end of the main shaft 2 is located at the center of the cross bar 3, and the two ends of the cross bar 3 are respectively connected to one (or more than one) blades that can swing. Connect two baffles 4 (two at one end, 4 in total). Each blade is made up of rotating shaft 5 and blade 6. The blade 6 can be quadrilateral, trapezoidal, triangular, polygonal or arc-shaped.

There are three installation methods for paddles and baffles:

1. Parallel installation type (rotating shaft is parallel to the cross bar): the rotating shaft 5 is installed in parallel under the two ends of the cross bar 3, and the two ends of the cross bar 3 are respectively connected with two upper and lower baffles 4, and the upper baffle 4 is set on The back of cross bar 3 two ends, and can touch with it when making paddle forward to parallel shape with water flow. The baffle plate 4 below is located at the below of the cross bar 3 two ends, and can be blocked by it when the paddle is turned to the vertical shape with the water flow. The paddle swings between the upper and lower baffle plates 4 with the rotating shaft 5 as the center, and the maximum swing angle is 90°.

2. Vertical installation (the shaft is perpendicular to the cross bar): the shaft 5 is vertically inserted into the two ends of the cross bar 3 from bottom to top or from top to bottom, and the two ends of the cross bar 3 are respectively connected with two inner and outer baffles 4 , outside baffle plate 4 is located at the outside of cross bar 3 two ends (and with cross bar 3 on the same straight line), and can be blocked by it when making paddle forward to and vertical shape with water flow. The baffle plate 4 of inner surface is located at the inboard of cross bar 3 two ends backs, and makes the minimum included angle that paddle blade and cross bar 3 form after being blocked by it be 45 °. The paddle swings between the two baffles 4 with the rotating shaft 5 as the center, and the swing angle (∠poq and ∠p'o'q' in the figure) is at most 135°.

3. Inclined installation type (the rotating shaft and the cross bar are inclined): the rotating shaft 5 is obliquely inserted into the two ends of the cross bar 3 .

Fig. 2 and Fig. 3 are a specific embodiment of the utility model, to illustrate the action of the utility model.

When the steering wheel 1 rotates back and forth in the angle range between 30° and 90°, the cross bar 3 makes corresponding strokes.

As shown in Figure 2, when the steering wheel 1 turns counterclockwise, the right side of the crossbar 3 swings forward, and the paddle at the right end of the crossbar 3 follows the water flow to turn parallel to the direction of the water flow; at the same time, the left side of the crossbar 3 Swipe backwards, when the blade at the left end of the cross bar 3 is rotated to be perpendicular to the water flow direction by the water resistance, the outer baffle plate on the left side of the cross bar 3 blocks and is in the backward stroke. The reaction force pushes the left side of the boat to swim forward.

As shown in Figure 3, when the steering wheel 1 rotates clockwise, the left side of the crossbar 3 swings forward, and the paddle at the left end of the crossbar 3 follows the water flow to turn parallel to the direction of the water flow; at the same time, the right side of the crossbar 3 Swipe backwards, the paddle at the right end of the cross bar 3 is blocked by the outer baffle plate on the right side of the cross bar 3 when it is rotated to be perpendicular to the water flow direction due to the water resistance, and the paddle is stroked backwards. The reaction force pushes the right side of the boat to swim forward.

In this way, under the back and forth rotation of the steering wheel, the left and right sides of the boat can swim back and forth to move forward.

To sum up, these are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. All ordinary technical personnel in this industry can smoothly implement the utility model as shown in the accompanying drawings and the above description; When the above-disclosed technical content can be utilized, the equivalent changes made to make some changes, modifications and evolutions are equivalent embodiments of the present utility model; at the same time, all modifications made to the above embodiments according to the substantive technology of the present utility model All changes, modifications and evolutions with equivalent changes all still belong to the scope of the technical solution of the present utility model.
