Description

Underwater propulsion system using jet principle

The present invention relates to an underwater propulsion device using a jet principle, and more particularly, two propellers, an underwater motor, and a battery are configured inside the first body and the second body to be symmetrically coupled to each other, so that the propeller is rotated and the propulsion force is increased. And further screw grooves are formed inside the propulsion system so that the water flowing through the propulsion system can cause eddy currents and strong jet phenomena so that it can quickly escape the distress and respond quickly to emergency situations. In addition, it prevents survivors from drifting or curling up at vortex points such as high-speed rivers and algae, and can easily escape the inexperienced or swimmers. Jet phenomena in the city can reduce the health of the distress. The present invention relates to an underwater propulsion device using a jet principle that can be separated from the backboard and combined with a separate surfboard to be utilized for everyday leisure.

In general, life jackets are made in the form of vests using buoyancy materials, and buoyancy materials that float on the water inside the life jackets are provided. Even if you do not, you are preventing asphyxiation by water.

These life vests are essential elements to be worn when riding a marine vessel or boat, and in the event of an emergency where even a swimmer can fall into the water, buoyancy of the life vest prevents a person from floating in the water. Prevents asphyxia.

In particular, life jackets are one of the water safety products worn to prevent the occurrence of safety accidents when playing in the river or sea, or when playing water leisure sports such as windsurfing or rafting. It has the basic functions to injure the body and additional functions to prevent the body from lowering the temperature and shock from the outside.

Conventionally used life jackets are largely divided into a method of providing a tube in the space between the endothelial and the outer shell and injecting air therein, and a buoyant material made of a foamed resin is installed between the inner shell and the outer shell. There is an inconvenience in injecting or discharging air, and when the tube is damaged, the life jacket loses its function, so in most cases, a life jacket provided with a buoyant material of a foaming resin is used.

The life jacket is composed of a front part that is worn on the upper body and surrounds the chest and abdomen, and a rear part that surrounds the back part, and foam resin buoyancy materials of the same thickness are installed in the front part and the rear part, and the life jacket is buoyant. The wearer is made to float.

In addition, a support band is provided at the bottom of the front portion and the rear portion so that the life jacket wearer's legs are fitted to maintain the wearing state of the life jacket firmly.

However, since such a life jacket simply performs a function of allowing a survivor, ie, a drowning person, to float in the water, if the distressed person has been in the water for a long time, the body may have a low body temperature due to low body temperature or physical consumption. The rhythm drops sharply, causing problems such as human accidents.

In addition, if the missing person is a vortex where waves gather into one place, or where the tide is severe, or where a rapid current occurs, rather than a lifebuoy floated by buoyancy, the distress may be severely shaken or There is a problem of being floated away.

As a result, when a person is far from the missing place, the rescue operation is difficult and the time for rescue is delayed. Therefore, the body, except for the face of the person who is distressed, is left in the water for a long time, causing the hypothermia or exhaustion of the person. The situation is exposed to great danger that can endanger the lives of the people.

In this regard, the present applicant has devised a life jacket equipped with a screw, which is a patent application No. 10-2009-0099131, which is connected to the back plate which is located on the back of the user, and is connected to the back plate and the connection belt and is located on the back of the user. In the life jacket consisting of a backboard which is, the submersible motor is configured in the interior of the backboard and screwed on the lower side; A battery configured to be electrically connected to the submersible motor, the battery configured to supply power to the submersible motor, respectively; In the life jacket equipped with a screw consisting of a switch that is electrically connected to the submersible motor on / off to expose the surface of the subboard to turn on / off the motor, the upper end of the subboard further comprises a direction control unit, the direction control unit The support plate which is fastened to the upper surface of the back plate by a bolt and a nut; The top of the support plate is centrifugally coupled by a rotating pin, the direction key is protruded on the rear, and the front surface consists of a handle plate formed with a handle for rotating the direction of the direction keys to the left or right.

Therefore, by constructing a screw that is rotated by the driving of the motor in the lower part of the life jacket, even if drowned in water, the distress person can escape the distress place by using the rotation of the screw without having to stay in the distress place. We expect effect to be able to cope.

However, there is an urgent need for an underwater propulsion system that can escape the distress accident area more quickly and quickly.

The present invention has been made to solve the problems of the conventional life jackets used, by combining the propeller equipped with two propellers with the backboard and the life jacket into one, two propellers are rotated by the driving force of the underwater motor, the driving force is And a screw groove is formed inside the propulsion device so that water flowing through the propulsion device becomes a vortex phenomenon, causing a strong jet phenomenon to quickly escape the distress area so as to respond quickly to an emergency situation. In addition, it prevents survivors from drifting or curling up at vortex points such as high-speed rivers and algae, and can easily escape the inexperienced or swimmers. Of the displaced by the jet phenomenon It is, and it is an object to provide an underwater propulsion device using a separately removable sternum and the jet principle, combined with extra surfboards to utilize for everyday leisure.

A second body composed of a second inner body having a second outer body fixed at both ends and having a semi-circular second accommodating part formed at an inner center thereof; An underwater motor accommodated inside the first accommodating part of the first body and the second accommodating part of the second body; First propellers and second propellers which are respectively arranged on both sides of the submersible motor and rotated by the rotational driving force of the submersible motor; In the underwater propulsion device consisting of a fixed body for fixing the first body and the second body symmetrical to each other is fitted to the first hinge portion of the first body and the second hinge portion of the second body, the first body Partition walls defining a partition space by partitioning between the first outer body and the first inner body and the second outer body and the second inner body constituting the second body; A battery retracted into the compartment space formed by the partition walls and electrically connected to the submersible motor; Elastic clips elastically coupled to the outer surfaces of the first and second outer bodies of the first body and the second body to protect the first propeller and the second propeller on the upper and lower portions of the first body and the second body. It further comprises a protector formed on the outer surface.

In addition, by simply pressing the switch of the life jacket, the propeller can be easily rotated to get out of the distress, so it is easy to use. Respond promptly in case of distress.

In addition, the propeller can be moved to the desired position by the rotating propeller, and jet thrust is generated by the screw groove to prevent the distressed person from being swept away or swept away by the vortex, such as a high-speed river, high waves, and high algae. It can prevent drowning of drowning drowning person.

In addition, the underwater motor, the propeller and the battery are coupled to a single body composed of the first body and the second body by the jet propulsion principle, and can be combined with a surfboard or water play equipment to enjoy a variety of water play, thereby increasing the usability. In addition, since the batteries are respectively drawn into the compartment space formed by the partition walls formed on the first body and the second body, the operation time of the underwater motor, which is a power source for rotating two propellers by several batteries, is extended. In addition, a strong propulsion force can be generated, so that the displaced person can easily escape from the distress place and the operation of the underwater motor is stopped during the escape.
