<Example>

1 is a conceptual diagram illustrating an operation of an offshore mobile system according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view illustrating a configuration of an offshore mobile system according to an embodiment of the present invention. 3A to 3C are perspective views for explaining the configuration of a seawater pocket and a displacement plate in an offshore mobile system according to an embodiment of the present invention, and FIG. 4 is a view showing the configuration of a weight module in the offshore mobile system according to an embodiment of the present invention. It is a perspective view for explanation.

As shown, the marine moving system according to the embodiment of the present invention sucks seawater from the front in a state supported by a support member (L1) below the watercraft 200 floating on the sea level and the watercraft 200. At the same time, it is composed of an unmanned submersible 100 that generates a propulsion force F1 by spraying seawater from the rear so that the watercraft 200 can be dragged. (For reference, reference numeral W1 is seawater sucked from the front of the submersible 100, and reference numeral W2 is seawater injected from the rear of the submersible 100)

Hereinafter, the marine moving system according to the embodiment of the present invention will be described in detail, focusing on each component.

The watercraft 200 may be equipped with various equipment according to the purpose of the marine moving system. For example, communication and marine measurement equipment 230 may be installed on the hull 210, and in addition, a solar power generation device 220 for providing power to the communication and marine measurement equipment is preferably installed.

As described above, the unmanned submarine 100 converts the vertical motion of the watercraft 200 by waves to generate a propulsive force for dragging the watercraft 200 located at the sea level, and continues without a separate energy supply. It is structured to be able to move forward. To this end, the unmanned submersible 100 includes a housing 110, a seawater pocket 120, a displacement plate 130, a seawater suction check valve 140a, 140b, and a seawater injection check valve 150a, 150b, and a weight module. It is made including 160.

In the unmanned submarine 100, the housing 110 is a streamlined member having an internal space and is configured to move up and down along the watercraft 200 that is elevated by a wave. The support member (L1) is connected to the upper and lower ends of the water line 200 and the housing 110, respectively. In the case of the support member (L1), it may be provided with a flexible rope or cable, but as shown in the drawing, the upper part and the lower part are provided as a straight bar hinged to the watercraft 200 and the housing 110, respectively. It is desirable. As a result, when the watercraft 200 descends, the housing 110 can be pushed and lowered, so that the housing 110 immediately reacts and ascends and descends as the watercraft 200 moves up and down. Of course, the support member L1 may also be provided with a flexible rope, and in this case, the housing 110 does not immediately descend when the watercraft 200 descends, so it may be relatively less efficient. Therefore, when the support member L1 is not provided as a straight bar but is provided as a flexible rope, a compression spring 136 that pushes the displacement plate 130 to be displaced downward from the inside of the housing 110 If possible, it must be installed.

The seawater pocket 120 is installed so as to be able to contract and expand in the housing 110, and when expanded, it sucks and stores seawater in front of the housing 110, and when contracted, the stored seawater is sprayed to the rear of the housing 110 for propulsion. It plays the role of generating. To this end, the seawater pocket 120 is installed in the form of a corrugated pipe capable of expanding and contracting for suction and injection of seawater. The seawater pocket 120 is disposed upward and downward with respect to each other, and the upper pocket 120a has an upper end fixed to the housing 110, and a lower end composed of a fixed end fixed to the housing 110. It is provided as a pocket 120b, and a displacement plate 130 that is displaced relative to the housing 110 is installed between the upper pocket 120a and the lower pocket 120b.

In this way, according to the configuration in which the seawater pocket 120 is provided with an upper pocket 120a and a lower pocket 120b, the housing 110 rises (arrow H1) while the water line 200 rises by blue as shown in FIG. 5A. In this case, the displacement plate 130 has an inertia to stay as it is and is relatively displaced downward (arrow G1) with respect to the housing 110. In this case, while the upper pocket 120a expands, the seawater is sucked and stored in front of the housing 110, while the lower pocket 120b contracts and sprays the stored seawater from the rear of the housing 110 to provide a driving force to advance forward. Is obtained. On the other hand, as shown in FIG. 5B, when the housing 110 descends (arrow H1) while the water vessel 200 descends by the wave, the displacement plate 130 has an inertia to stay as it is and upwards with respect to the housing 110. Is the relative displacement (arrow G1). In this case, when the upper pocket 120a is contracted, the stored seawater is injected to the rear of the housing 110, and the lower pocket 120b is expanded and the seawater is sucked from the front of the housing 110 to obtain a driving force to advance forward. In the configuration of the seawater pocket 120, it should be noted that even if the displacement plate 130 is displaced in either the upward or downward direction inside the housing 110, the seawater is sucked from the front of the housing 110 and at the same time, the seawater is sucked from the rear. As the motion of spraying is continued, it generates a driving force that can move forward.

Here, the seawater suction upper hose 121a and the seawater suction lower hose 121b connecting the front ends of the upper pocket 120a and the lower pocket 120b and the housing 110 are installed for seawater suction, and seawater injection For this purpose, an upper hose 122a for seawater spraying and a lower hose 122b for seawater spraying are installed connecting the rear end of the upper pocket 120a and the lower pocket 120b and the housing 110, respectively. And the upper first check valve (140a) and the lower first check valve (140b) allowing the flow of seawater only in the direction in which seawater is sucked, respectively, in the upper hose 121a for seawater suction and the lower hose 121b for seawater suction. Is installed, and the upper second check valve 150a and the lower second check valve allowing the flow of seawater only in the direction in which seawater is injected, respectively, in the upper hose 122a for seawater injection and the lower hose 122b for seawater injection. (150b) is installed.

Meanwhile, only one seawater pocket 120 may be installed in a form in which an upper pocket 120a and a lower pocket 120b are stacked as shown in FIG. 3A. In addition, it is also possible to be installed side by side in a parallel form as shown in Fig. 3b or 3c. In this case, the above-mentioned seawater suction upper hose (121a) and seawater suction lower hose (121b), seawater injection upper hose (122a) and seawater injection lower hose (122b), each check valve also seawater pocket 120 ) Must be installed in a number corresponding to the number of installations. As such, in the case of a configuration in which a plurality of seawater pockets 120 are installed in a parallel form, it is a structural way to secure a larger capacity of the seawater pocket 120 in a relatively large submersible 100, and simply seawater based on the same capacity In the case of increasing the number of installations of the pockets 120, it can be used to maintain a balance during propulsion by increasing the number of seawater suction and injection points. In the case where a plurality of seawater pockets 120 are installed, even if some seawater pockets 120 are damaged or malfunction, it is also a great advantage in that the propulsion force can be continuously generated by the other seawater pockets 120.

The displacement plate 130 is installed so as to be displaceable in a state coupled to the seawater pocket 120 inside the housing 110, so that the seawater pocket is displaced relative to the housing 110 as the watercraft 200 is elevated by the waves. It serves to induce the forward suction and rear injection of seawater by deforming (120). To this end, the displacement plate 130 is formed of a metal plate having an area not to interfere with the inside of the housing 110 and is installed between the upper pocket 120a and the lower pocket 120b. The displacement plate 130 is displaced later than the housing 110, which is directly elevating according to the elevation of the water vessel 200 due to the action of inertia, thereby causing the seawater pocket 120 to be deformed. When the displacement plate 130 is relatively displaced downward from the inside of the housing 110, the upper pocket 120a is expanded to suck seawater from the front of the housing 110 and store it, while the lower pocket 120b is contracted and stored. The existing seawater is injected from the rear of the housing 110. In addition, when the upper pocket 120a contracts and injects the stored seawater from the rear of the housing 110, the lower pocket 120b expands and expands the seawater in the front of the housing 110 when the upper pocket 120a is displaced upward from the inside of the housing 110. Is induced to inhale and store.

In order to guide the vertical displacement of the displacement plate 130, in the housing 110, a pair of two or a pair of four guide rods 135 vertically installed while passing through the displacement plate 130 is further provided. Is installed. In addition, a coil-type compression spring 136 is wound and installed on an upper portion of the guide rod 135 around the displacement plate 130. The compression spring 136 is supported so as to operate stably without shaking when the displacement plate 130 is displaced in the vertical direction along the guide rod 135. In this way, when the vertical displacement of the displacement plate 130 is stably achieved by the installation of the guide rod 135 and the compression spring 136, as a result, the expansion and contraction of the seawater pocket 120 are stably achieved, while the suction and injection of seawater Is made stably, and the driving of the submersible 100 is also made more stable. The role of the compression spring 136 is exerted when the support member L1 is provided with a flexible rope rather than a bar, as described above. In this case, in place of the support member (L1), which becomes loose when the watercraft 200 descends by the wave, the compression spring 136 moves the displacement plate 130 in a downward direction relative to the housing 110, and the seawater pocket Induces the generation of the deformation and propulsion of (120).

On the other hand, the weight module 160 suspended from the housing 110 by a connection rope L2 to the lower side of the housing 110 serves to stably prevent shaking of the submersible 100. To this end, the weight module 160 is made of a metal material as a whole, as shown in FIG. 4, a frame 161 having a vertical portion in which vertical guide grooves 161a are formed on the inner surfaces facing each other, and the vertical portion It consists of a plurality of weights 162 stacked in a pair of spaced spaces and a bent plate shape, and is integrally joined in a form surrounding the lower portion of each weight 162, and both ends protrude to the left side and the right side to form a pair of It is composed of a separation preventing bending plate (162a) to prevent the separation of the weight in the state inserted into the vertical guide groove (161a). Here, a slit-shaped cutout 161a is formed on the front side wall of the frame 161 so that both protruding ends of the bent plate 162a are inserted. It should be noted that in this configuration, the weight module 160 is not formed in a single mass, but is formed in a form in which weights 162 are stacked. According to this configuration, there is an advantage in that the weight can be flexibly imparted by adjusting the number of stacked weights 162 so that the submersible 100 does not shake according to an increase in water depth or movement of seawater.

According to this configuration, the displacement plate 130 is directly elevated along the water vessel 200 that is elevating and descending by the wave, and the housing 110 exhibits a slow reaction speed due to the inertia of staying in place, resulting in a displacement difference between each other. This will deform the seawater pocket 120. Here, as shown in FIGS. 7A and 7B, the support member L1 must be bent at the point where it is inserted into the housing 110, so unlike the previous embodiment, the support member L1 is not provided with a rigid straight bar, but is provided with a flexible rope. Here, a pair of rollers 111 is installed to guide the support member L1 to the entrance and exit of the housing 110 to prevent frictional damage so that the support member L1 can be smoothly in and out of the housing 110. It is desirable to be.

In the case of the marine moving system according to the first modified embodiment of the present invention configured as described above, the displacement plate 130 rises with respect to the housing 110 when the water vessel 200 rises due to blue as shown in FIG. 7A, and the upper pocket (120a) and the lower pocket (120b) contract and expand, respectively, and the displacement plate 130 descends with respect to the housing 110 when the watercraft 200 descends, so that the upper pocket 120a and the lower pocket 120b Each expands and contracts. Here, when the water vessel 200 descends, the support member L1 is in a loose state, and at this time, the displacement plate 130 is installed on the upper part of the guide rod 135 so that the displacement plate 130 quickly descends downward from the inside of the housing 110. The compression spring 136 pushes the displacement plate 130 downward.

Other detailed configurations of the first modified embodiment that are not described are substantially the same as those of the previous embodiment, and thus descriptions thereof will be omitted.

Accordingly, when the displacement plate 130 is displaced upward, the seawater pocket 120 expands and the seawater is sucked and stored in front of the housing 110, and when the displacement plate 130 is displaced downward, the seawater stored while contracting It is characterized in that the injection to the rear of the housing 110.

In this case, the seawater suction lake 121 and the seawater injection lake 122 are connected to the lower end of the seawater pocket 120, and the first check valve 140 and seawater allow the flow of seawater only in the direction in which seawater is sucked. Each of the second check valves 150 are installed to allow the flow of seawater only in the direction in which the is sprayed.

On the other hand, in the second modified embodiment of the present invention, the support member L1 is provided with a flexible rope that penetrates the housing 110 and connects the water vessel 200 and the displacement plate 130 as in the first modified embodiment. The displacement plate 130 is lowered between the housing 110 and the displacement plate 130 so that the displacement plate 130 can be relatively displaced in the downward direction with respect to the housing 110 when the water vessel 200 descends by the wave. A compression spring 136 that pushes in the direction is installed.
