Description

Technical Field

[0001] The present invention relates to a marine propeller, in particular to an electric propeller driven by a new energy battery. One propeller is installed on each side of a willow leaf boat. The propeller is composed of a joystick handle, a joystick connecting rod, a controller, a support beam, a motor, a propeller bracket, a propeller, a guide plate, etc. The propeller is called a double-sided electric propeller for a willow leaf boat. The present invention is also applicable to canoes, kayaks, paddle boards, etc. Background Art

[0002] Willow leaf boats are small boats that are as slender as willow leaves and pointed at both ends. They are often seen in rivers with gentle currents, especially in southwest my country and many countries in Southeast Asia, South Asia, South America, Latin America, and Africa. In order to better counter the flow rate of water and carry more cargo, people will make the boats slender and long. Since the stern is also pointed, it is impossible to install the propeller that hangs on the stern like we usually see. Instead, a diesel engine propeller with a long propeller is used. The control handle is also long, and the propeller extends a long way from the stern to fall into the water. This kind of boat has the disadvantages of slow speed, loud propeller noise, pollution, and people can only stand to operate it and are prone to fatigue.

[0003] The present invention installs an electric propeller on each side of the willow-leaf boat, which not only greatly improves the speed of the boat but also allows people to operate it while sitting. These boats often go out to transport goods for a whole day, and people will not be so tired when sitting. The propeller adopts electric propulsion, and the power size can be arbitrarily configured. The new energy battery has a long battery life, and charging saves a lot of money compared to using diesel. The electric propeller is noiseless and pollution-free, and is an environmentally friendly product. It is the direction of future development.

[0004] The invention is also applicable to watercraft such as canoes, kayaks and paddleboards, which are light and easy to carry, convenient to use, and improve efficiency and sailing speed compared to hand paddling. Summary of the invention

[0005] The present invention is improved based on the characteristics of the slender stern of the willow leaf boat, and is designed to install a propeller on each side of the willow leaf boat. No long rod is needed. With the same power, the volume of the electric propeller is much smaller than that of the diesel engine, and the two sides of the willow leaf boat are not much wider. One joystick controls the two propellers, and people can operate it while sitting.

[0006] The present invention is implemented as follows: a support beam is provided across the sides of the boat, a support beam clamp is provided to clamp the sides of the boat and is fixed with screws, a sleeve is provided on the rotating shaft of the motor, the sleeve passes through a propeller bracket, a water pressure plate and a propeller are provided at the lower end of the rotating shaft, the propeller bracket has a clamp to clamp the support beam and then tighten, a controller and a new energy battery are connected, and the installation is completed, a water pressure plate and a propeller are provided at the lower end of the rotating shaft of the motor, the rotation of the motor drives the propeller to rotate, and pushes the boat forward, the function of the water pressure plate is to reduce water splashes, a stepless speed regulating knob is provided on the joystick handle, the controller controls the battery charging and discharging, and has a power switch, forward and reverse buttons, a cruise control button operation key and a power and speed display, a connecting rod connects the two propeller control handles, the joystick handle or the connecting rod is swung left and right for steering control, and one joystick handle is used to control the two propellers, and a guide plate is provided at the front end of the propeller to reduce water flow resistance.

[0007] The technical effects of the present invention are: 1. The electric propeller has a variety of power and is not as large as a diesel engine, so it can be easily disassembled and taken home; 2. It can be charged anytime and anywhere, and the cost of use is lower than gasoline and diesel, and it can also be charged by solar photovoltaics; 3. It is easy to operate and multifunctional; 4. It is noiseless and pollution-free; 5. The power is much greater than that of a diesel engine.

[0008] The electric propeller introduced in the present invention has a propeller protected by an outer cover and a tail rudder plate under the propeller. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] from Figure 1 , Figure 2 , Figure 3 and Figure 4 As can be seen from the figure, the bilateral dual electric propellers introduced in the present invention have support beams 7 crossing the sides 10 of the boat, support beam clamps 8 clamp the sides 10 and fix them with screws, the rotating shaft of the motor 5 is wrapped with a sleeve, the sleeve passes through the propeller bracket 9, the lower end of the rotating shaft is provided with a water pressure plate 11 and a propeller 6, the propeller bracket 9 has a clamp to clamp the support beam 7 and then tighten, connect the controller 2 and the new energy battery, and the installation is completed, the lower end of the rotating shaft of the motor 5 is the water pressure plate 11 and the propeller 6, the rotation of the motor 5 drives the propeller 6 to rotate, and pushes the boat forward, the function of the water pressure plate 11 is to reduce the splash, the joystick handle 1 is provided with a stepless speed regulating knob, the controller 2 controls the battery charging and discharging, and has a power switch, forward and backward buttons, a cruise control button operation key and a power and speed display, a joystick connecting rod 3 connects the two propeller handles, the joystick handle 1 or the joystick connecting rod 3 is swung left and right for steering operation, so that one joystick handle 1 can operate two propellers, and a guide plate 4 is provided at the front end of the propeller to reduce water flow resistance.

[0018] Figure 5 The boat shown is a willow-leaf boat propelled by a diesel engine 12, which is still in widespread use today. The joystick is very long, extending three or four meters from the stern, making it inconvenient to operate. The key point is that this propeller is not only noisy, but also has low thrust and slow speed. There is an exhaust port 13 that emits black smoke, and oil often pollutes the water surface.

[0019] The propeller of the electric propeller introduced by the present invention is protected by an outer cover.
