Description
Technical Field
The present invention relates to a life saving unit for rescuing a flood victim, and more particularly, to a propulsion unit of a life buoy which can be stably propelled even if a buoyancy body provided to the flood victim is overturned.
Background
In general, drowning accidents often occur in places where water sources such as rivers, lakes, reservoirs, sea are abundant. These drowning accidents are caused by the lack of timely and proper countermeasures against emergency situations, such as lack of swimming experience, loss of foothold on the ship, and capsizing of the ship. Therefore, life-saving equipment is installed at a place where drowning accidents frequently occur, or a live life-saving person is disposed to prevent the drowning accidents from occurring. These drowning accidents occur because such emergencies occur unexpectedly and in most cases do not provide timely assistance. In some unfortunate situations, ordinary people who have not received adequate safety and rescue training participate directly in the rescue and drown with drowners.
In addition, for a drowned person nearby, the drowned person can be saved by throwing a life-saving tube (tube), rope, rod, etc. to the drowned person while in water. However, if the distance from the drowner is too large, even if the life-saving pipe or rope is thrown to the drowner, there is a high possibility that the life-saving pipe or rope will fail because it cannot reach the drowner or does not reach the correct position. Even if successful, it takes a lot of time and drowners may lose consciousness or miss ropes etc. making all rescue work futile.
Thus, there is a strong need for a rescue means that can more safely and more quickly deliver a rescue tube to a drowning person and guide the drowning person to a safe location.

And, at least one or more repositioning members 300 are provided and coupled to the auxiliary fixing member 200.
Further, a repositioning member 300 is provided at the rear end of the auxiliary fixing member 200, wherein the repositioning member 300 is configured to rotate the deployment position (disposition position) of the propelling member 400 by a predetermined angle.
Specifically, when the buoyancy body 100 floats on the water surface, the repositioning member 300 changes the position of the propulsion member with reference to the water surface, so that the position of the propulsion member can be placed under water.
More specifically, the repositioning component 300 includes a housing 310, a drive module 320, and a coupling 330.
First, a predetermined space is formed in the housing 310 to accommodate the driving module 320.
The drive module 320 is then configured to change the position of the propulsion component.
At this time, the driving module 320 is separated from the housing 310, wherein a portion of the driving module 320 is accommodated in the housing 310.
Herein, although not particularly shown in the drawings, a sealing member made of an elastic material may be provided to prevent external water from penetrating into a separation space formed due to a detachable coupling structure between the driving module 320 and the housing 310.

Further, the module body 321 is configured to be slidingly coupled to the housing and is housed within the housing 310. By adopting the above coupling structure, simpler coupling and uncoupling can be performed by sliding and fixing the module main body into the housing, thereby improving maintenance convenience.
The control unit 322 is coupled to the module body 321 and configured to control driving of the driving module.
Next, a power supply unit 323 is coupled to the module body 321 and supplies power to the driving module, wherein the power supply unit may include a battery capable of charging and discharging.
The driving member 324 is configured to drive the repositioning member 300, wherein the driving member 324 is powered by the power unit 323 and operates to change the position of the propulsion member 400 according to a control signal generated by the control unit 322.

Further, the slide coupling part 340 is configured to be coupled by sliding along the extending direction of the guide member 210 described above.
At this time, the guide member 210 is extended in the advancing direction while being fixed to the buoyancy body, and a guide groove having a predetermined width is formed in the extending direction so that the sliding coupling part 340 can be seated thereon.
Further, the sliding coupling part 340 slidably moves along a guide groove formed on the guide member to be coupled to the guide member 210. By having the coupling structure as described above, when the repositioning member 300 is mounted, the repositioning member can be mounted more conveniently by aligning the mounting direction of the repositioning member.
Next, the pushing members 400 are fixed to the repositioning member 300, wherein at least one pushing member 400 is provided to move the buoyancy body 100, and the pushing members corresponding to the number of repositioning members 400 are provided.
In this context, the propulsion unit of the life buoy is provided with propulsion members 400 to enable rescue without throwing the life buoy towards the drowned person during a rescue operation, so that the life buoy can safely approach the location of the drowned person without risk of collision between the thrown life buoy and the drowned person.
Furthermore, the propulsion unit of the life buoy can change the position of the propulsion member 400 by the repositioning member 300, thereby enabling more stable propulsion with respect to the buoyancy body 100.
Accordingly, the propulsion unit of the life buoy can place the position of the propulsion part 400 under water by the repositioning part 300, thereby providing a more stable propulsion effect.
As shown in fig. 4, repositioning component 300 includes a drive 324 and a coupling 330.

Further, the coupling 330 is configured to couple to the propulsion component 400.
Specifically, the coupling 330 has a rotation axis parallel to the advancing direction of the advancing member 400.
Herein, the coupling 330 is coupled to the driving member 324 and the propulsion member 400, respectively. Thus, even if the buoyancy body 100 is tipped over and falls on the water surface, the driving member 324 is operated so that the propulsion member 400 located on the water surface can rotate under the water surface.
In addition, the repositioning member 300 has a coupling 330, the rotation axis of which is parallel to the advancing direction of the advancing member 400 and rotates, so that the advancing member 400 can rotate more accurately under water. Thus, a more improved propulsion stability can be ensured.
Accordingly, the buoyancy body 100 can be operated normally, and the buoyancy body 100 is located on the water surface regardless of whether the buoyancy body 100 is in a normal state. Thus, during life-saving actions, even if the buoyant body 100 falls on the water surface in a tipped state, the buoyant body 100 can quickly and safely approach the position of a drowned person without re-throwing the buoyant body 100.
