Embodiment 1

[0022] combine Figure 1-Figure 3 , this embodiment includes four parts: an underwater paddle unit, a paddle rotation unit, a paddle stroke unit and a housing fixing unit. The underwater blade unit is installed on the blade rotating unit, and the blade rotating unit is connected with the blade paddling unit, and these two moving units must be installed on the shell fixing unit.

[0023] combine figure 1 , the underwater paddle unit is a symmetrical paddle paddle 1 adapted to paddling underwater. The blade rotation unit consists of a rotation unit servo motor 8, a motor fixing plate 12, a motor fixing ring 13, a motor barrel 9, a motor barrel front cover 17, a motor barrel rear cover 10, a motor shaft sleeve 18, a small bearing 5, a seal 4, 11,15, cylindrical pin 3, connector 2 and real rotating shaft 14 and hollow rotating shaft 6 constitute. The rotary unit servo motor 8 is installed in the motor barrel 9 and fixed on the front cover 17 of the motor barrel through the moto...

Embodiment 2

[0028] combine Figure 4 , this embodiment is based on Figure 4 The state installs the device in a single set at the tail of the submersible, that is, as Figure 4 The scull board 30 shown is at the rear of the casing 21 and is in the water; the paddle unit motor 22 is at the front of the casing 21 and inside the submersible. At this time, the moving direction of the submersible should refer to the left side of the drawing. Figure 4 The right part shows a cross-sectional schematic diagram of the scull board 30 , and it can be seen from the figure that the cross-section of the scull board is streamlined. When the scull swings from side to side, the top of the scull (that is, the surface facing the water) is slightly protruding, and the bottom (that is, the surface facing the water) is slightly concave, resulting in different water pressures and generating forward thrust. Such as Figure 4 state, the rotating unit motor 8 starts counterclockwise at first, so that the scull bo...

Abstract

The invention provides an underwater paddling propulsion device. It includes a shell fixing unit, an underwater blade unit, a blade rotating unit and a blade padding unit, the blade rotating unit is installed in the shell of the shell fixing unit through a rotating shaft, and an arrangement is made between the rotating shaft and the shell There is a sealing mechanism, the underwater paddle unit is connected with the paddle rotation unit, the paddle paddle unit is a motor installed outside the shell of the fixed unit of the shell, and the paddle paddle unit and the paddle rotation unit are connected through a transmission mechanism . The invention is compact in structure and easy to install, and can be installed symmetrically on both sides of the submersible in multiple sets, and can be installed on the tail of the submersible in a single set.

Description

(1) Technical field [0001] The invention relates to the technical field of underwater propulsion, in particular to an underwater paddling propulsion device for an underwater vehicle. (2) Background technology [0002] In order to navigate, the underwater vehicle must have propellers. Propellers on underwater vehicles can almost all be found in the propellers of ships, but due to various reasons, propeller propulsion is the most common traditional propulsion method in water currently applied to underwater vehicles. In the process of R&D and application of underwater vehicles, the traditional propulsion methods, such as high noise and low efficiency, seriously restrict the development of underwater vehicle speed, maneuverability, energy consumption and other technologies. To expand, the development of underwater propulsion technology for underwater vehicles is very necessary, and the research and development of various propulsion technologies is imminent. (3) Contents of th...
