Description

Technical Field

[0001] The utility model relates to marine equipment, in particular to a power propeller. Background Art

[0002] Most of the existing marine propulsion devices use manual joysticks to control steering. For example, CN218085955U electric scattering boat discloses a technical solution for steering by joystick. The disadvantage of this type of solution is that manual operation is not convenient enough. In some improvements, such as CN217456311U, a remote-controlled wind propeller specifically discloses a solution for controlling the steering of the propeller by a motor. However, this type of solution is still not comprehensive enough. The device that drives the propeller to turn is set at a lower position, which is very easy to encounter water and cause rust and damage to the equipment. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a power propeller.

[0004] The power propeller is provided with a vertical pole fixed on the ship, a flat plate which can rotate around the vertical pole is provided on the top of the vertical pole, a wind propeller is installed on the flat plate, a driving device is installed under the flat plate, the driving device is connected to the flat plate, and the flat plate is driven to rotate by the driving device.

[0005] In this solution, the driving device is raised by a vertical pole to prevent the driving device from coming into contact with water. The water here refers to, for example, water brought up by fishing nets, a small amount of water accumulated on the boat due to rain, etc., which overflows the equipment, or water stepped on the driving device when walking on the boat. In this solution, the flat plate arranged on the top of the vertical pole, in addition to being used as a platform for installing the wind propeller, has a more important purpose, taking into account the situations where the driving device comes into contact with water from top to bottom due to rain, casting nets, etc., and after the driving device is installed under the flat plate, it can prevent the equipment from coming into contact with water in these situations.

[0006] Furthermore, the driving device is a linear telescopic device, which can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod. The advantages of using a linear telescopic device are that it has the advantages of simple structure, easy installation, easy maintenance, light weight, and small burden.

[0007] Furthermore, considering that it is too expensive to install a hydraulic pump or an air pump on a small boat to provide power for a hydraulic telescopic rod or a pneumatic telescopic rod, preferably, the linear telescopic device is an electric telescopic rod.

[0008] More specifically, the electric telescopic rod comprises a rod body and an inner rod that can be telescoped relative to the rod body, the bottom of the flat plate is provided with a first fixed shaft extending vertically downward, the tail of the rod body is provided with a fixed sleeve that allows the rod body to be sleeved on the first fixed shaft, a nut is screwed at the bottom of the first fixed shaft, and the rod body can be installed on the first fixed shaft after being sleeved on the first fixed shaft, the outside of the vertical rod is provided with a horizontally extending fixed seat, the top of the fixed seat is provided with a second fixed shaft extending vertically upward, and the front end of the inner rod is provided with a mounting rod that allows the inner rod to be sleeved on the second fixed shaft; when the inner rod is telescoped relative to the rod body, it can drive the flat plate to rotate; the advantage of this solution is that the electric telescopic rod can be dismantled by removing the nut and then removing the inner rod of the electric telescopic rod from the second fixed shaft, which is not only convenient for installation and maintenance, but also convenient for re-converting the remote-controlled power device into a manually operated power thruster, which can give users more flexible choices.

[0009] The utility model also provides another design of a driving device, wherein the driving device includes a servo motor, which is fixed under the flat plate. A first gear is fixed on the main shaft of the servo motor, and a second gear meshing with the first gear is fixed on the vertical rod. The flat plate is driven to rotate by the servo motor.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model provides a power propeller capable of realizing automatic steering of a wind propeller, and the design of the installation position of the driving device for driving the wind propeller to steer can well protect the driving device itself, effectively avoiding the situation where the driving device encounters water.
