Description

A propulsion apparatus of the underwater}

The present invention relates to a personal underwater propulsion device, and more particularly, it is possible to move quickly in the water by a propeller formed on the bottom of the stern, the second body slides inside the first body, the size of the diver's height and convenience of land movement The present invention relates to a personal underwater propulsion device whose length can be adjusted according to gender.

In general, the underwater propulsion apparatus has been developed in various forms for the rapid movement of people or smooth progress of underwater work. However, these submarine propulsion systems are large submarines and relatively small submersibles, which are difficult to move and use individually in terms of volume and cost, and are not exposed to enemies, especially in groups where individuals move and operate underwater. It was difficult to use.

As a prior art to improve this, the Republic of Korea Registered Utility Model Publication (No. 20-0364888) "Underwater propulsion device" as shown in Figure 1, the propulsion device 100 for generating a propulsion force; A power supply device 300 for supplying power required for driving the propulsion device 100; And a mounting apparatus 200 for mounting the propulsion apparatus 100 to the mounted object. It includes, The propulsion device 100, Casing 110 is opened and closed so that water can flow through; A propeller 120 provided to discharge the water received in front of the casing 110 by rotating while being seated and supported in the casing 110; And a motor 130 that receives power from the power supply device 300 and rotates the propeller 120.

However, the prior art as described above has a problem in that it is difficult for a diver or an operator to maintain a uniform posture due to the characteristics of the propulsion device fixed to the back of the body, and thus it is difficult to move in a desired direction.

In addition, if the diver's or man's fitness falls or is misdirected, the diver is not only dangerous, but also another problem that may cause the diver or man in danger due to collisions with floating materials floating in the sea or underwater while moving at high speed. There was this.

In order to solve the problems as described above, in the present invention, the front of the first body is closed in a structure in which the front of the first body is closed to prevent the diver or man from being injured by the floating material in the water when moving at a high speed. It is formed to provide a personal underwater propulsion device formed on the inner side of the first body is a guide rail is moved to the guide bar fixed to the second body so that the length is adjusted according to the body structure of the diver or manipulator.

In addition, there is a further object to provide a personal underwater propulsion device in which both ends of the control handle and the extension shaft formed on the first body are respectively connected by a second cable so that the diver can easily change the direction from underwater to up, down, left and right. .

The present invention is a personal underwater propulsion device formed with a bow and a stern, the transparent window formed of a transparent plastic material so that the front is identified on the front of the bow, a plurality of circular fixing grooves are formed in the longitudinal direction along the open inner surface of the upper A first body having guide rails fixed to the left and right sides in the longitudinal direction; A second body having a guide bar fixed to the left and right ends of the deck end of the planar shape in a longitudinal direction and inserted into the guide rail, and having an extension plate protruding from the center of the stern bottom; The motor is wrapped in a motor housing on the bottom of the stern and sealed, and a motor having a propeller coupled to one end, a battery fixed in an airtight space formed inside the deck, electrically coupled with the motor, and the propeller wrapped around the top and bottom of the stern, respectively. A protruding portion having a nozzle fixed to a bottom surface and an end of an extension plate, and an extension shaft having an “a” shape protruding from the upper part of the motor housing to be inserted into and fixed to a closed space; Both ends are inserted and rotated on both sides of the rotating shaft fixed to the inner bottom surface of the bow, the control handle fixed to the center of the rotating shaft and rotated clockwise / counterclockwise, and the rotating groove protruding from the rear end of the second body. And a control unit having a second cable formed with one end fixed to the control handle and the other end fixed to the extension shaft.

In addition, the second body has a diameter smaller than the first body, the guide bar is inserted into the guide rail is formed to be fixed by inserting a fixing bolt in the fixing groove after moving to the inside / outside of the first body.

In addition, the motor housing is formed so that the second cable is fixed to the extension shaft to rotate left and right about the extension shaft when the control handle rotates clockwise / counterclockwise.

In addition, the horizontal wing is connected to one end of the control handle is formed so that the other end through the first cable pipe fixed to the stern bottom is rotated when the control handle moves back and forth by the first cable fixed a predetermined distance away from the rotation groove do.

As described above, the personal underwater propulsion device according to the present invention has an effect of easily changing the direction of the water by rotating the control handle clockwise / counterclockwise by connecting the control handle and the extension shaft by the second cable.

In addition, the guide bar fixed to the second body is inserted into the guide rail fixed to the inner surface of the first body is moved after the second body is moved to the inside of the first body to adjust the body length according to the body conditions of the diver or manipulator There is another effect that can be used.

In addition, through the transparent window formed on the front of the athlete it is easy to check the front of the movement, and only one side is opened in a cylindrical shape concealed the position of the diver or the operator is another structure that can prevent the diver from injury during operation of the underwater propulsion system It works.
