Abstract
The utility model provides a collapsible screw of four leaves for underwater propulsor, include the paddle, install cap at the bottom of the screw of underwater propulsor tip, be equipped with four fixed positions at the bottom of the screw on the cap, be equipped with the smooth pin in surface on the fixed position, paddle swing joint in on the pin, close the motor when adopting the glide mode when the navigation ware, the screw receives the resistance of water automatic folding, and the very big water contact face that has reduced the water resistance, and the very big resistance that comes from the screw that has reduced has improved glide speed.
Description
Technical field
This utility model relates to marine technology equipment field, and particularly relating to a kind of four leaves for underwater propeller can
Fold propeller.
Background technology
Current most of submarine navigation device, such as underwater robot, underwater glider etc., mostly uses motor to drive
Propeller rotation mode realizes motor control.The propeller used mostly is fixed multiple-blade propeller, when under water
The when that aircraft using no-power way to glide, there is great water engaging surface in fixed multiple-blade propeller,
Aircraft will be produced great resistance, slow down the speed of service of submarine navigation device.
Utility model content
For solving above-mentioned technical problem, the utility model proposes a kind of four leaves for underwater propeller collapsible
Propeller, including blade, be installed on underwater propeller end propeller at the bottom of cap, cap at the bottom of described propeller sets
Having four fixed bits, described fixed bit is provided with ganoid pin, and described blade is movably connected on described pin
Nail on.
Preferably, cap at the bottom of described propeller is annular, is provided with female thread inside cap at the bottom of described propeller.
Preferably, described fixed bit includes two stators that be arranged in parallel, and described stator is provided with through hole, institute
State pin and be provided with hold-doun nut through described through hole and described pin, described blade be positioned at described stator it
Between.
Preferably, described fixed bit crossing distribution is on cap at the bottom of described propeller.
Preferably, described blade is made up of carbon fiber.
Preferably, described blade is helical structure.
The four collapsible propellers of leaf for underwater propeller that the utility model proposes have following beneficial effect: when
When aircraft closes motor employing glide mode, propeller, by the resistance auto-folder of water, is greatly reduced water
Contact surface, reduces water resistance, is greatly reduced the resistance from propeller, improves gliding speed.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical scheme in this utility model embodiment
It is clearly and completely described.
In conjunction with Fig. 1, Fig. 2, Fig. 3, the utility model proposes a kind of four leaves for underwater propeller 8 can
Fold propeller, including blade 1, be installed on underwater propeller 8 end propeller at the bottom of cap 2, described spiral
Cap 2 at the bottom of oar is provided with four fixed bits 3, and described fixed bit 3 is provided with ganoid pin 4, described oar
Leaf 1 is movably connected on described pin 4, and wherein, described fixed bit 3 includes two stators 6 that be arranged in parallel,
Described stator 6 is provided with through hole, and described pin 4 is provided with fixing spiral shell through described through hole and described pin 4
Cap 7, described blade 1 is between described stator 6, and cap 2 at the bottom of described propeller is annular, described spiral
It is provided with female thread 5 inside cap 2 at the bottom of oar, cap at the bottom of propeller 2 is fixed on angle of rake motor shaft, pushes away under water
Entering device 8 when working under water, driven by motor motor shaft rotates, thus drives blade 1 to rotate, four blades 1
Launched to rotate by centrifugal action under the driven by motor of high speed rotating, complete to push away hydrodynamic(al) and make, when motor stops rotation
Turning, submarine navigation device moves, before four blades 1 are turned to parallel and propeller by the resistance of water along pin 4
Enter direction, reduce the contact area with water, reduce resistance；
In order to make blade 1 on pin 4 freely rotatable, pin 4 surface carries out smooth treatment；
As shown in Figure 4, described fixed bit 3 crossing distribution is on cap 2 at the bottom of described propeller.
As it is shown in figure 5, described blade 1 is made up of carbon fiber, described blade 1 is helical structure, compares tradition
Propeller metal material has higher structural strength and corrosion resistance, is more suitable in abyssal environment using.
Multiple amendment to embodiment will be apparent from, herein for those skilled in the art
Defined General Principle can be implemented at other in the case of without departing from spirit or scope of the present utility model
Example realizes.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is intended to symbol
Close the widest scope consistent with principles disclosed herein and features of novelty.
