Definitions of these terms should be made based on the contents throughout this specification.

Hereinafter, the configuration and function of the algae-based lifting device of the present invention will be described with reference to FIGS. 1 to 6.

The algae meter 600 is installed in the sea near the loading dock 10 to measure environmental information such as the speed and direction of the algae, water temperature, and the like. The algae system 600 may be submerged below sea level and exposed to the underwater environment of the sea for a long time.

As shown in FIG. 2, in the conventional algae-based lifting method, the algae system 600 is moored by a wire 20, and for this purpose, a weight 11 is connected. The wire 20 and the weight 11 submerged in the sea are caught or combined with fish, seaweed, and marine floats, and as a result, excessive tension may be applied to the wire 20 and the wire 20 may be broken. In addition, when lifting the tidal current 600, the cable 30 and the wire 20 are twisted, so that the cable 30 may be disconnected and a contact failure may occur. The cable 30 may be for transmitting measurement information of the tidal stream 600 to the ground or supplying power to the tidal stream 600.

In addition, since the corrosion of the wire 20 exposed to salt for a long time may occur, it may occur that the tension applied during lifting cannot be maintained.

In addition, the wire 20 or the cable 30 submerged in the sea may be entangled due to waves or tides in the sea.

Sea level refers to the surface of the sea and can be assumed to be a virtual plane for explanation.

The loading dock (10) is a mooring dolghin area that binds the mooring lines so that the vessel does not move and does not move, or a moored dolphin region that can dock the hull, and the vessel is moored to embark passengers. It may be a port facility that can be ordered or loaded and unloaded. The unloading pier 10 may be a building material of wood or concrete.

As shown in Figure 1, the algae-based lifting device of the present invention is coupled to the algae system 600 and the mobile unit 300 and vertical movement in the direction perpendicular to the sea level, and the mobile unit 300 is perpendicular to the sea level It may include a guide unit 100 to guide in one direction. The guide unit 100 may be fixed to the unloading port 10.

As shown in Figure 5, the mobile unit 300 is inserted into the guide unit 100, the mobile unit 310 moves in accordance with the extending direction of the guide unit 100, and the tidal current meter 600 on one side It may be fixed and may include a plate portion 320 to which the moving part 310 is fixed on the other side. The moving part 310 is coupled to the upper part of the plate part 320, the tidal current system 600 is coupled to the lower part of the plate part 320, and the lower end of the moving part 310 and the upper end of the tidal current system 600 are a certain distance. D or more can be separated. At this time, the direction of gravity in the direction perpendicular to the sea level is defined as down and the direction of opposite gravity is defined as up.

That is, the moving part 310 may be coupled to the upper part of one side of the plate part 320, and the algae system 600 may be coupled to the lower part of the other side of the plate part 320. The plate portion 320 may be a hard material having corrosion resistance and high rigidity.

Components submerged in the sea may adhere to fish, seaweed, and floating matters, and accordingly, a mechanism for mechanically driving a component that has been submerged for a long time in the water may place a burden on the device. Therefore, a structure in which the moving part 310 is not submerged in the sea may be desirable. However, the algae system 600 must be submerged as a device for measuring the underwater environment in the sea.

In the algae-based lifting device of the present invention, by using the plate part 320 as an intermediate connecting member between the algae system 600 and the moving part 310, the moving part 310 and the algae system 600 are vertical to the sea level. Since a certain distance is connected to the separated state, the moving part 310 may not be simultaneously dive into the sea together with the algae system 600. That is, only the algae system 600 is submerged in the sea, and the moving unit 310 may exist on the sea level.

The moving part 310 has a lower limit of vertical movement at a point that does not fall below the sea level, and only a lower portion of the plate part 320 coupled with the moving part 310 may be submerged in the sea.

Therefore, in the algae-based lifting device of the present invention, the diving depth of the algae system 600 is related to the separation distance D in a direction perpendicular to the sea level between the lower end of the moving part 310 and the upper end of the algae system 600, This may be determined as a length in a direction perpendicular to the sea level of the plate portion 320.

The algae system 600 may be fixed to the plate portion 320 by bolts. Specifically, the algae system 600 may be coupled to the plate portion 320 by U-bolt. U-bolt, also called Danski bolt, means a horseshoe-shaped bolt.

Part of the submerged part of the algae-based lifting device of the present invention may be a bolt for fixing the lower part of the plate part 320, the algae system 600 and the plate part 320. The part of the algae-based lifting device of the present invention that is submerged in the sea is simplified so that no problem occurs when the algae system 600 is lifted, even if it is exposed to sea water for a long time or if a foreign object is stuck.

In addition, since the submerged part of the algae-based lifting device of the present invention is made of a material having high rigidity and can maintain its original shape even in the tide of the sea, the wire 20 and the like are entangled in the device. A phenomenon in which a failure occurs may be solved, and a separate weight weight 11 may not be required.

A lifting unit 500 is installed at the unloading pier 10 to provide power for vertical movement in the direction perpendicular to the sea level, and the lifting unit 500 and the moving unit 300 are wires ( 20), the lifting unit 500 may raise the mobile unit 300 by applying a tension to the wire 20.

The lifting unit 500 may be a crane device installed on the upper surface of the unloading pier 10. Specifically, the lifting unit 500 may be a jib crane that loads the tip of the arm with one boom.

As shown in FIG. 5, one end of the wire 20 may be coupled to the upper end of the plate part 320 or the moving part 310.

The plate part 320 is made of a larger size compared to the moving part 310 and the tide gauge 600, and the moving part 310 and the tide gauge 600 may be installed on both sides, respectively, and the moving unit 300 The center of gravity of) may be located on the plate portion 320 or adjacent to the plate portion 320. Accordingly, the wire 20 pulling the mobile unit 300 upward may be preferably connected to the upper end of the plate portion 320.

Since the moving part 310 moves inside the guide pipe part 110, friction occurs between the moving part 310 and the guide pipe part 110, so that the moving unit 300 moves on the moving part 310 side. A friction force may be generated in the direction, and the mobile unit 300 may be inclined during movement due to the friction force. Therefore, it may be desirable to connect the wire 20 pulling the mobile unit 300 upward to the upper end of the mobile unit 310 in order to offset the corresponding frictional force and prevent the mobile unit 300 from tilting.

The meaning that the mobile unit 300 is inclined may mean that the plate portion 320 is inclined based on the normal attitude when the plate portion 320 is standing in a direction perpendicular to the sea level.

In one embodiment, the wire 20 includes a first wire 21 and a second wire 23, the first wire 21 is coupled to the plate portion, the second wire 23 is a moving portion 310 ), The lifting unit 500 may raise the mobile unit 300 by applying tension to the first wire 21 and the second wire 23.

The algae-based lifting device of the present invention connects the wires 20 to the plate portion 320 which is the center of gravity and the moving portion 310 where frictional resistance occurs, and pulls them at the same time, so that the mobile unit 300 is tilted during operation. You can prevent it from losing.

The tide lifting device of the present invention is a wire drum installed on the lifting unit 500 to wind the wire 20 and a cable drum wound on the cable 30 installed on the lifting unit 500 and connected to the tidal current meter 600. It may include. Here, the wire 20 means a string pulling the tidal current 600 due to tension, and the cable 30 is an electric wire that exchanges electrical signals with the tidal current 600 or supplies power to the tidal current 600. Can mean

If the wire 20 is wound for lifting at the time of lifting the tidal current system 600, the length of the cable 30 remains as the length of the wire 20 decreases, and the cable 30 is caught or entangled in the surrounding structures. Can be. Therefore, it may be good to wind the wire 20 while lifting the tidal current 600 while simultaneously winding the cable 30. That is, it may be desirable for the wire drum and the cable drum to wind the same length per unit time.

The guide unit 100 may include a guide pipe 110 in which one end is fixed to the unloading port 10 and the other end extends toward the sea level.

The guide pipe part 110 and the moving part 310 may have a cylindrical shape extending in a direction perpendicular to the sea surface.

3 and 4, the guide pipe portion 110 may be a hollow elongated pipe. The moving part 310 may move along the length direction of the guide pipe part 110 inside the guide pipe part 110. Therefore, the outer diameter of the moving part 310 may be smaller than the inner diameter of the guide pipe part 110. That is, the guide pipe part 110 may be a rail for the moving part 310 to move.

A guide long hole 115 forming a long axis in the longitudinal direction of the guide pipe portion 110 may be formed on the outer surface of the guide pipe portion 110. The guide long hole 115 may be formed by drilling a side surface in a pipe pipe constituting the guide pipe part 110 along a longitudinal direction of the pipe.

The mobile unit 300 may include a connecting portion 330 connecting the moving portion 310 and the plate portion 320 to which the algae system 600 is fixed. The connection part 330 may penetrate the guide hole 115 and connect the moving part 310 inside the guide pipe part 110 and the plate part 320 outside the guide pipe part 110. One end of the connection portion 330 is fixed to the side wall of the moving portion 310, the other end is fixed to one surface of the plate portion 320, the connection portion 330 may pass through the guide hole 115.

Therefore, when the moving part 310 is moved while sliding inside the guide pipe part 110, the connection part 330 coupled with the moving part 310 slides along the guide long hole 115 together with the moving part 310. Can be moved.

The guide pipe part 110 may include a stopper that contacts the lower end of the moving part 310 to limit the downward movement of the moving part 310.

When the moving part 310 and the guide pipe part 110 serving as a rail of the moving part 310 are immersed in the sea, seafood, seaweed, and marine floats are coupled to the moving part 310 or the guide pipe part 110 Or, the shape is deformed due to corrosion by seawater, and the movement of the moving part 310 may be prevented. It may be desirable that the length of the moving part 310 is not submerged in the sea. Therefore, it may be preferable that the algae-based lifting device of the present invention is designed such that the moving part 310 does not descend below the sea level. To this end, a stopper for allowing a lower limit in the moving section of the moving part 310 may be provided in the guide pipe part 110 which is a rail of the moving part 310.

The stopper can limit the movement of the moving part 310 by blocking any point inside the guide pipe part 110. Since the stopper is for limiting the downward movement of the moving part 310, the stopper may contact the lower end of the moving part 310.

Alternatively, the stopper may restrict a movement of the moving portion 310 by blocking a part of the long hole to limit the movement of the connection portion 330 connected to the moving portion 310.

As shown in FIG. 6, the guide pipe part 110 is a rotation axis 111 in a direction perpendicular to the longitudinal direction of the guide pipe part 110 by using a point at which one end of the guide pipe part 110 is fixed as a support point. Can be rotated.

The guide pipe unit 110 may be deformed, such as warping or torsion, due to collision of ships or marine floats, or environmental changes such as swelling waves. Due to the deformation of the guide pipe, the moving part 310 may be caught inside the guide pipe part 110 to limit movement. In order to cope with such an accident, the algae-based lifting device of the present invention can be rotated with the rotating shaft 111 in a direction perpendicular to the longitudinal direction of the guide pipe portion 110. Since the support point of the guide pipe portion 110 is located at the unloading pier 10, when the guide pipe is rotated 90 degrees, the tidal stream 600 can be raised to the height of the unloading pier 10.

The guide pipe portion 110 may be supported by a single point on the unloading pier 10 in order to be fixed to the unloading pier 10 in a rotatable structure. The unloading pier 10 may be worn due to weathering or corrosion because it is made of a material such as concrete or wood. At this time, the wear can be accelerated by fixing the device to the unloading pier 10 with one point. To prevent this, the support plate 113 is fixed to the side of the unloading pier 10 with a plurality of support means (bolts, etc.), and the guide pipe portion 110 can be fixed to the support plate 113. That is, the rotation shaft 111 of the guide pipe portion 110 may be installed on the support plate 113.

The guide unit 100 may include a pipe support portion 120 that contacts one side of the guide pipe portion 110 to limit rotation of the guide pipe portion 110. The pipe support 120 may extend in a direction perpendicular to the sea level.

Since the guide pipe 110 is supported by the rotating shaft 111 which is one support point to the unloading pier 10, in the normal operation state, the guide pipe 110 is restricted from rotating about the rotating shaft 111. It may be necessary. The pipe support 120 may be fixed so that the longitudinal direction of the guide pipe 110 is directed in a direction perpendicular to the sea level.

The normal operating state is a state before an accident such as a collision with a ship or a marine floating object or an environmental change such as a swelling wave occurs in the guide pipe part 110, the guide pipe part 110 without deformation such as bending or twisting ). That is, the normal operating state may mean a state in which the moving part 310 does not have any problem in moving inside the guide pipe part 110.

The algae-based lifting device of the present invention has a fixed distance spaced apart in the horizontal direction of the sea level from the support wire (the position of the rotational shaft 111 of the guide pipe part 110) and the take-off wire that is connected to the guide pipe part 110 at one end. It may include an auxiliary lifting portion 510 to rotate the guide pipe portion 110 by pulling the wire out at the point. That is, the auxiliary lifting part 510 for pulling the guide pipe part 110 by applying tension to the take-out wire may be a device that provides a driving force to the rotational movement of the guide pipe part 110.

The auxiliary lifting part 510 may be fixed to the unloading pier 10, and preferably may be positioned at the same height as the rotation shaft 111 of the guide pipe part 110. Here, the height may mean a distance from the sea level in a vertical direction.

The support point (guide pipe part 110) at a point where one end of the take-out wire connected to the guide pipe part 110 is distanced from the auxiliary lifting part 510 to a support point (the position of the rotation shaft 111 of the guide pipe part 110) ) May be the same as the distance to the rotational axis 111. By equalizing the two distances, it is possible to minimize the energy required to rotate the guide pipe portion 110.
