Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, preferred embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

1 is a perspective view showing the appearance of a portable underwater propulsion device according to an embodiment of the present invention, Figure 2 shows a state of use of the portable underwater propulsion device according to an embodiment of the present invention.

As shown in Figure 1 and 2, the portable underwater propulsion device 100 according to an embodiment of the present invention is mounted on the waist portion of the diver (A) to provide a driving force to assist the movement of the diver (A). By providing the divers A to move faster with minimal stamina consumption, freeing both hands of the divers A who need to use various underwater equipment, perform the underwater operation and search more safely and efficiently. Do it.

Such a portable underwater propulsion device 100 according to an embodiment of the present invention, as shown in Figures 1 and 2, at least one or more to provide a driving force to assist the movement of the diver A in the water Propeller 110, at least one weight (120) to provide a weight that allows the diver A to maintain the neutral buoyancy, and the multi-purpose belt 150 worn on the waist of the diver (A) .

Here, the portable underwater propulsion device 100 according to an embodiment of the present invention, as shown in Figures 1 and 2, at least one battery 130 for supplying power to the propeller 110, and wired or It may further include a controller 140 for controlling the operation of the propeller 110 through wireless communication.

Hereinafter, each component of the portable underwater propulsion device 100 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The propeller 110 is mounted at a predetermined position of the utility belt 150 to provide a propulsion force for the diver A to move underwater. The propulsion unit 110 may vary in the mounting position or the number of mounting according to the required propulsion force, considering the balance of the propulsion efficiency and the diver (A) during swimming, as shown in Figures 1 and 2, diver (A) In the state in which the multi-purpose belt 150 is worn, it is preferable to mount the pair of propellers 110 at positions corresponding to both sides of the diver A. However, as described above, the mounting position or the number of mounting of the propeller 110 may be variously applied according to the purpose of underwater work, etc., it is apparent that the present invention is not limited to this embodiment.

Such a propeller 110 may be implemented as a conventional propulsion equipment consisting of a motor and a propeller, but only a small equipment that can be mounted on the multipurpose belt 150, which can be carried by divers according to the purpose of the present invention Is preferred. In addition, the propeller 110 has a deceleration function that can provide a step-by-step propulsion force by adjusting its output according to the operation of the controller 140 to be described later, and a wired line capable of transmitting or receiving a control command from the controller 140. Or it is desirable to be able to provide a wireless communication function. Such a propeller 110 may be selected from various types of propellers 110 by varying the propulsion method or the propulsion force according to the purpose of the underwater operation.

The weight 120 is mounted at a predetermined position of the multipurpose belt 150 to provide a weight for the diver A to maintain the neutral buoyancy in the water. In general, when the diver (A) proceeds to underwater work by diving, it is necessary to maintain the neutral buoyancy by offsetting the positive buoyancy received by the diver (A) and the wetsuit itself. The weight 120 serves to provide a weight for offsetting such positive buoyancy, and is usually provided in the form of a weight of lead.

Since the weight of the diver (A) or the weight of the underwater equipment varies, the weight or number of mounting of the weight (120) mounted on the multi-purpose belt 150 must also be selected in various ways. At this time, it is common for the diver (A) to wear all the equipment and breathe on the surface of the water to float, and to select the weight or the number of mounting weight 120 to provide a weight that is slightly sinking when exhaled desirable. The simplest way to calculate the proper weight is to take 10% of the weight of the diver A to the required weight. That is, when the weight of the diver (A) is 80kg, it is possible to select the mounting weight or the number of mounting weight 120 to provide a weight of 8.0kg. In this case, for example, if using the weight 120 of 1kg, it is preferable to mount the eight weights 120 to the multi-use belt 150. However, in the above-described example, since the weight of the underwater equipment such as a wetsuit is not taken into consideration, the weight or the number of mounting of the weight 120 according to the weight of the underwater equipment such as the wetsuit should be finely adjusted.

The versatile belt 150 is equipped with a propeller 110 and a weight 120, is worn on the waist of the diver (A). The multipurpose belt 150 allows the propeller 110 to be positioned at the waist of the diver A, so that the diver A can not only obtain propulsion when moving in water, but also freely use both hands for underwater operation and navigation. You can make it proceed. This versatile belt 150 may be configured in the form of a conventional weight belt consisting of a strap made of plastic or stainless steel buckle and hard nylon, and attaches the weight 120 according to the purpose of underwater work, Or in the form provided with a pocket that can put the weight 120 can be used.

Mounting position or the number of mounting of the propeller 110 mounted on the multi-purpose belt 150, as described above, can be variously selected depending on the propulsion efficiency and the balance of the diver (A), mounting of the weight (120) The weight or number of mountings may also be variously selected depending on the weight of the diver A or the weight of the underwater equipment.

The battery 130 supplies power required by the propeller 110 and may be provided in the form of a battery pack including one or more batteries according to the use period of the propeller 110. The battery 130 may be provided in various forms according to the power required by the propeller 110, but a rechargeable battery form that can be reused through charging is preferable.

The battery 130 may be mounted at any place, for example, an oxygen tank case (not shown), as long as the battery 130 is not limited to the movement of the diver A and the underwater work according to the object of the present invention. However, the weight 120 described above is essential for underwater work, but considering that there is no special function other than maintaining the neutral buoyancy and that the battery 130 also has a significant self-weight, the degree of neutral buoyancy maintenance Accordingly, if the battery 130 is mounted on the multipurpose belt 150 by replacing some or all of the weights 120, it is very desirable to reduce the number of equipment to be mounted while maintaining the neutral buoyancy essential for underwater work.

Accordingly, the portable underwater propulsion device 100 according to the present embodiment has a plurality of weights mounted on the multipurpose belt 150 in consideration of the amount of power required and the weight required for maintaining the neutral buoyancy according to the use time of the propeller 100. In place of some or all of the weight 120, the battery 130 is provided by mounting the multipurpose belt 150. In this case, if the power supply cable 151 is provided inside the multipurpose belt 150 to directly supply power to the propeller 110 from the battery 130 mounted on the multipurpose belt 150, an unnecessary cable or the like is externally provided. This would not be exposed and would be more desirable.

In order to explain in more detail the relationship between the weight 120 and the battery 130 mounted on the multi-purpose belt 150, the weight of the weight 120 and the battery 130 is 1kg, respectively, the power supply time of one battery It is assumed that this 1 hour, the required time of use of the propeller 110 is 4 hours, the weight of the diver (A) is assumed to be 80kg. First, the weight required to maintain neutral buoyancy is 8.0 kg (see the appropriate weight calculation example above), and the number of batteries required is four. Therefore, in this case, if the four weights 120 and four batteries 130 are mounted on the multipurpose belt 150, the weight of 8.0 kg required for neutral buoyancy and four hours of propeller 110 can be met. Will be. Similarly, in the above example, since the weight of the underwater equipment such as a wet suit is not taken into consideration, it is a matter of course that the weight of the weight 120 and the battery 130 need to be adjusted more precisely.

The controller 140 is worn on the wrist of the diver A to control the operation of the propeller 110 through wired or wireless communication. For example, the diver A may control the speed of movement by controlling the deceleration function of the propeller 110 to provide stepped thrust force through the controller 140. The controller 140 and the propeller 110 may transmit or receive a control command in a conventional wired or wireless manner, and it may be more preferable that the controller 140 and the propeller 110 be implemented in a wireless manner due to the nature of underwater work.

In addition, the controller 140 is provided with a small monitor 141 that displays the remaining amount of the battery 130. The diver A checks the remaining amount of the battery 130 displayed through the small monitor 141 of the controller 140, and determines whether the underwater work is continued, the moving distance, the return, etc. You can do it.

The controller 140 may be mounted at any position as long as the diver A can easily control the operation of the propeller 110. However, when considering the remaining amount check function of the battery 130 and the simple operation of the diver A, the controller 140 is worn on the wrist of the diver A, as shown in FIGS. 1 and 2. It is preferable. To this end, the controller 140 is provided with a wrist wearing band 142 that can be worn on the wrist of the diver (A), the wrist wearing band 142 is in the form of a flexible rubber band or belt with a buckle. And the like.

2 illustrates a state of use of the portable underwater propulsion device 100 according to an embodiment of the present invention.

As shown in Figure 2, the portable underwater propulsion device 100 according to an embodiment of the present invention is worn on the waist portion of the diver (A) by providing a driving force to assist the movement of the diver (A), In addition to allowing divers to move faster while minimizing physical expenditure, freeing both hands of divers A, who must use various underwater equipment, enables them to perform underwater operations and navigation more safely and efficiently. do.

As shown in FIG. 2, in the portable underwater propulsion device 100 according to the embodiment of the present invention, a pair of propellers 110 are provided at a position corresponding to both sides of the diver A. It is attached to 150. In addition, the plurality of propellers 110 and the plurality of weights 120 are mounted on the multi-use belt 150 according to the weight of the propulsion unit 110 as described above and the weight required for maintaining the neutral buoyancy.

The diver A controls the operation of the propeller 110 through the controller 140 worn on the wrist, performs underwater work while adjusting the moving speed, and checks the remaining amount of the battery 130 displayed on the controller 140. You can determine underwater work time, travel distance, return status, and more.
