Description

Water man-driven leisure boat

The utility model relates to a human-driven recreational boat on water, in particular to a human-driven recreational boat with leisure and interest, a sense of speed and sports properties.

There are quite a wide range of leisure activities on the water, such as surfing, water skiing, jet skis, human-driven leisure boats, etc. Although the above-mentioned various activities are interesting to a certain extent, they also have certain restrictions. Water skiing must be towed by an external force, jet skis are expensive and cause environmental pollution, and are generally prohibited from being used on sightseeing lakes. Human-driven leisure boats do not need to be towed by external forces and will not cause environmental pollution, and the scope of use is relatively small. Restricted, but due to lack of speed and lack of fun, it is gradually facing elimination.

The traditional human-driven leisure boat is to set a runner on both sides of the hull with a diameter higher than the hull. There are multiple blades on the runner. The runner is driven by the sprocket. After the wheel turns, the runner can be rotated, and the blades on the runner paddle the water surface to drive the hull forward, but because the diameter of the runner is larger than the hull, the driving is more laborious and the speed is relatively slow, not only the speed is extremely slow , and after the blade leaves the water, it will splash water and easily wet the user's clothing. Based on these defects, the user's interest is lacking.

Therefore, the main purpose of the present utility model is to provide a human-driven leisure boat on water which is faster and less likely to splash water, which can create more fun and arouse users' interest.

The purpose of this utility model is achieved in that:

A water human-driven leisure boat, including a hull, a driving mechanism arranged inside the hull, and a steering mechanism that controls the forward direction of the hull, is characterized by:

The rear end of the hull is provided with a pipe fitting exposed at the bottom of the hull, and the bottom of the hull is cut in front of the pipe fitting to guide the water flow at the bottom of the hull to the inlet of the pipe fitting. There is a bearing seat, and it is equipped with bearings and waterproof gaskets;

The drive mechanism is provided with a drive sprocket, a gearbox and a propeller that extends the power to the interior of the pipe fitting. The center of the drive sprocket is provided with pedals on both sides, and each gear in the gearbox is driven by the sprocket.

The purpose of this utility model can also be further realized by the following technical means.

In the aforementioned manpower-driven leisure boat, the pipe fittings are conical pipes that taper from front to back.

In the aforementioned human-driven leisure boat, the steering mechanism is assembled by a flexible tube at the end of the pipe fittings. Both sides of the flexible tube are wound on a turntable via a rope connected by a pulley, and a direction controller is set on the turntable to control the rotation of the turntable. .

For the aforementioned manpower-driven leisure boat, one of the gears in the gearbox is equipped with a one-way ratchet, and a flywheel is coaxially installed.

In the aforementioned human-driven leisure boat, the front end of the pipe fitting extends upwards to an air duct to the top of the hull.

The utility model has the advantages: due to the use of a simple structural design, the speed of the manpower-driven leisure boat can be greatly increased to enhance its fun; When moving forward, there is no splash of water, and because the user must be driven by manpower, it also has the effect of movement.

Below in conjunction with accompanying drawing of specification sheet and embodiment, the technical content of the present utility model is further described:

Description of drawings:

Fig. 1 is the schematic plan view of the utility model;

Fig. 2 is a schematic diagram of the drive mechanism of the present utility model;

3 to 5 are schematic diagrams of the steering mechanism of the present invention and its operation.

First, as shown in Figure 1, the utility model is a human-driven leisure boat on water, which is mainly composed of a hull 10, a driving mechanism 20 and a steering mechanism 30 located inside the hull, wherein:

The rear end of the hull 10 is provided with a pipe fitting 11 that tapers from the front to the rear and protrudes from the bottom of the hull 10. A diversion surface 12 is cut in front of the pipe fitting 11 at the bottom of the hull 10 and extends to the entrance of the pipe fitting 11 for guiding The water at the bottom of the hull flows to the pipe fitting 11 inlet, and the guide surface 12 is provided with a bearing seat 13 on which a bearing 14 and a waterproof washer 15 are housed.

Cooperate shown in Fig. 2 by Fig. 1 in addition, driving mechanism 20 is made up of driving sprocket 21, gearbox 22 and propeller 23 that power is extended to the inside of the above-mentioned pipe by gearbox 22, and the center both sides of driving sprocket 21 are arranged Pedal 24 is arranged, and the inside of this gearbox 22 has a driven sprocket 221 that cooperates with the driving sprocket 21. The number of teeth of the driven sprocket 221 is less than that of the driving sprocket 21, and the driven sprocket 221 is coaxially provided with one more A gear 222 with a number of teeth, and a gear 223 with a small number of teeth meshed with the gear 222. The gear 223 is coaxially provided with a gear 224 with a large number of teeth, and a gear 225 with a small number of teeth meshed with the gear 224. The gear 225 is coaxially provided with a gear 226, the gear 226 meshes with another gear 227, the bevel gear 227 is installed on the shaft 228, the shaft 288 passes through the bearing seat 13 and is combined with the propeller 23, after the driving sprocket 21 rotates, it will pass through the gearbox 22 Each gear changes the transmission of the rotational speed ratio to drive the propeller 23 to rotate at a high speed.

As shown in Figure 1 and Figures 3, 4, and 5, the steering mechanism 30 is assembled at the end of the pipe fitting 11 by a flexible tube 31, and the two sides of the flexible tube 31 are wound on a rope 32 via a pulley 33. On the turntable 34, a direction controller 35 is set on the turntable 34 to control the rotation of the turntable 34. After the turntable 34 is rotated by the direction controller 35, the direction inclination angle of the end of the flexible tube 31 is changed by the pulling of the rope 32.

As shown in Figure 1 again, after the above-mentioned components are assembled, the user is placed inside the hull 10, and after stepping on the pedal 24 to make the drive sprocket 21 rotate, after the conversion of the high speed ratio of the gearbox 22, the propeller 23 Rotating at a high speed, the water is discharged backwards by the pipe fitting 11, generating a thrust to push the hull. Since the pipe fitting is in a state of tapering from front to back, the water flow in the pipe fitting 1 will be compressed and then discharged. This principle is similar to According to the turbine principle, the steering mechanism 30 controls the drainage direction of the end of the flexible pipe 31 connected to the rear end of the pipe fitting 11 to control the forward direction of the hull.

The utility model is to make the propeller 23 continue to rotate after the user stops stepping on the pedal 24. One of the gears in the gearbox 22 can be equipped with a one-way ratchet, and a flywheel 229 is coaxially installed to maintain the propeller 23. Inertial rotation, in addition, an air duct 16 is extended upwards to the top of the hull 10 at the front end of the pipe fitting 11 to guide air to the inside of the pipe fitting 11 to improve the ability of the pipe fitting 1 to compress water flow.

Since the structural design of brakes, waterproofing and flywheels of the hull are common technologies, they will not be described in detail in this manual.

To sum up, the structural features of this utility model are unprecedented, and can improve the defects of traditional human-driven leisure boats, and are progressive. Therefore, the structural features of this utility model are in line with the provisions of the Patent Law. application requirements.
