[0006] Korean Patent Publication No. 10-2017-0051204 (published on May 11, 2017) Summary of the invention

[0007] Problem to be solved

[0008] In the case of the floating water support device disclosed in the past, the support frame is combined with the ball. Here, the ball is supported by the floating part, so the ball can rotate. Therefore, the support frame also rotates around its central axis. At this time, if a wind turbine is installed on the support frame, the wind turbine rotates around its central axis. In this way, since the wings of the wind turbine do not face the front of the wind, there is a problem of reduced power generation.

[0009] The present invention is used to solve the above-mentioned problems, and an object of the present invention is to provide a floating water support device as follows: the support frame of the support structure can rotate around the ball, but cannot rotate around the axis of the support frame.

[0010] Means of solving the problem

[0011] The floating water support device of the present invention includes a ball, a floating tool and a support frame. The ball forms a guide groove along the circumferential surface. The floating tool has a floating part, and the floating part floats on the water to support the ball and rotate the ball. One end of the support frame is exposed on the water, and a structure is installed, and the other end is heavier than the one end, so as to stand vertically and pass through the circumferential surface to be connected to the ball. Among them, the floating tool also has a limiting protrusion, and the limiting protrusion is inserted into the guide groove to limit the ball from rotating around the axis of the support frame.

[0012] Furthermore, in the above-mentioned floating water support device, preferably, the floating tool further comprises a fixing member for mounting the limiting protrusion on the floating portion.

[0013] In addition, in the above-mentioned floating water support device, preferably, the ball is further formed with a fixing groove, and the fixing groove is formed on both sides of the ball and perpendicular to the central axis of the support frame on the path of the guide groove. In this case, the limiting protrusion is combined with the fixing member to advance and retreat in the radial direction of the ball with respect to the fixing member, and then can be inserted into the fixing groove.

[0014] In addition, in the above-mentioned floating water support device, preferably, the fixing component has a movable plate and a fixing frame. Combined with the limiting protrusion, when the limiting protrusion rotates, the limiting protrusion moves forward and backward, and the movable plate bends in the circumferential direction of the ball. The fixing frame is combined with the floating part to limit the movable plate to slide in the circumferential direction of the ball only within a predetermined spacing.

[0015] In addition, in the above-mentioned floating water support device, preferably, the fixing component further includes a clamp, and the clamp is combined with the fixing frame to pressurize the movable plate, thereby fixing the sliding of the movable plate.

[0016] In addition, the above-mentioned floating water support device also includes a blocking cover, which is combined with the floating part to prevent water that floats the floating tool from flowing into the ball.

[0017] The floating water support device of the present invention comprises a floating tool, a supporting tool and a mounting seat. The floating tool has a floating part floating on the water surface. The supporting tool has a coupling frame and a supporting frame, the coupling frame is coupled to the floating part, one end of the supporting frame is coupled to the coupling frame through a universal joint, and the other end is heavier than the one end to stand vertically. The mounting seat is exposed to the upper part of the floating tool to mount a structure at one end, and is coupled to the supporting frame.

[0018] In addition, the above-mentioned floating water support device also includes a blocking cover, which is combined with the floating part to prevent water from flowing into the universal joint.

[0019] Furthermore, in the above-mentioned floating water support device, preferably, the support frame is connected by joints and can be folded.

[0020] In addition, in the above-mentioned floating water support device, preferably, the weight of the support frame can be adjusted by injecting fluid at the other end.

[0021] Furthermore, in the above-mentioned floating water support device, preferably, the floating portion is formed by a hollow outer shell to accommodate the other end of the support frame inside.

[0022] In addition, the above-mentioned floating water support device also includes a solar panel, and the solar panel is arranged on the upper part of the floating part.

[0023] Effects of the Invention

[0024] According to the present invention, the limiting protrusion is inserted into the guide groove of the ball, so the support frame connected to the ball can be prevented from rotating around its central axis. Therefore, if a wind turbine is installed on the support frame, the shaft of the wind turbine can be prevented from rotating due to wind.

[0025] In addition, by the present invention, the movable plate can slide a predetermined spacing on the fixed frame. In this case, if the load of rotating the support frame around its axis is large, a part of the load can be absorbed, thereby preventing the restriction projection or the ball from being damaged due to excessive load.

[0048] Reference Figures 1 to 4 , describing an embodiment of the floating water support device of the present invention.

[0049] The floating water support device of the present invention includes a ball 10 , a floating tool 15 , a first support frame 25 and a solar panel 35 .

[0050] The ball 10 is formed with a guide groove 11 and a fixing groove 13. The guide groove 11 is formed along a circumferential surface of a virtual cross section passing through the center of the ball 10. That is, it is formed along a circumferential surface constituting the diameter of the ball 10. Then, the fixing groove 13 is formed on both sides of the ball 10 facing each other on the path of the guide groove 11 toward the center of the ball 10.

[0051] The first support frame 25 is coupled to the ball 10, and the other end is heavier than the one end 25a so as to stand vertically, so that the one end 25a is above the water surface and the other end is underwater. At this time, a structure such as a wind turbine can be installed at the one end 25a of the first support frame 25. When the first support frame 25 is coupled to the ball 10, it is coupled to the fixing groove 13 and vertically passes through the guide groove 11 and the center of the ball 10. The first support frame 25 is the same as the previous invention, and a fluid can be injected or discharged inside to change its weight. On the other hand, if Figure 5 As shown, the first support frame 25 can be connected with a hinge. This is to facilitate the disassembly and assembly of the floating water support device. In this way, fluid can be injected into the first support frame 25 or the foldable first support frame 25 can be applied to all embodiments described below.

[0052] The floating tool 15 includes a floating portion 16 , a limiting protrusion 17 , and a fixing member 20 .

[0053] The floating part 16 floats on the water and supports the ball 10. Therefore, a receiving part 16a for receiving and supporting the ball 10 is formed at the center of the floating part 16, and a cutting part 16b is formed, which is cut from the receiving part 16a to the outer peripheral surface, so that the first support frame 25 is located in the receiving part 16a or the other end of the first support frame 25 entering the water is lifted onto the floating part 16.

[0054] One end of the limiting protrusion 17 is inserted into the guide groove 11 to prevent the ball 10 from rotating around the axis of the first support frame 25. At this time, a screw is formed at the other end of the limiting protrusion 17 to move forward and backward in the fixing member 20.

[0055] The fixing member 20 plays a role in mounting the limiting protrusion 17 on the floating portion 16. To this end, the fixing member 20 includes a moving plate 21, a fixing frame 22 and a clamp 23.

[0056] The moving plate 21 is coupled to the other end of the limiting protrusion 17 by a screw, so that the limiting protrusion 17 can move forward and backward when the limiting protrusion 17 rotates. The moving plate 21 is formed to be curved in the circumferential direction of the ball 10 .

[0057] The fixing frame 22 is combined with the floating part 16 so that the movable plate 21 can only slide in the curvature direction of the movable plate 21 within a predetermined spacing. To this end, the fixing frame 22 guides the movable plate 21 to slide, and at this time, a collision rod 22a is formed, so that the movable plate 21 can only slide a predetermined spacing, and collide with the limiting protrusion 17 at a spacing corresponding to the spacing. That is, the limiting protrusion 17 only slides between the collision rods 22a at a predetermined spacing. Therefore, the movable plate 21 is the same as the collision rod 22a, and can also only slide within the spacing.

[0058] The clamp 23 restricts the sliding of the movable plate 21. Depending on the situation, it is necessary to fix the movable plate 21 instead of sliding the movable plate 21. In this case, the clamp 23 can be used to restrict the sliding of the movable plate 21. For this purpose, the clamp 23 is combined with the fixing frame 22, and then the movable plate 21 can be pressed if it is combined with the fixing frame 22. In the case of this embodiment, the clamp 23 can be screwed to the fixing frame 22, and then the movable plate 21 can be pressed.

[0059] The solar panel 35 is arranged on the upper part of the floating part 16. Therefore, the floating water support device of this embodiment can generate electricity by itself. In the case of this embodiment, although the solar panel 35 is arranged on the upper plate of the floating part 16, a vertical wind turbine generator may be arranged instead of the solar panel 35, or the solar panel 35 and the vertical wind turbine generator may be arranged together. The solar panel 35 and the vertical wind turbine generator may also be arranged in all the embodiments described below.

[0060] If the present embodiment is installed at sea, the first support frame 25 is vertically erected. In this case, the first support frame 25 is provided with a wind turbine or the like. If the rotation limiting protrusion 17 is inserted into the guide groove 11 of the ball 10, the ball 10 can be prevented from rotating around the axis of the first support frame 25. However, although the ball 10 is restricted from rotating around the axis of the first support frame 25, it can rotate around an axis perpendicular to the axis of the first support frame 25. Therefore, even if the floating portion 16 is shaken due to waves, the shaking of the floating portion 16 will not be transmitted to the first support frame 25.

[0061] However, at this time, the movable plate 21 equipped with the limiting protrusion 17 can slide a predetermined spacing. Therefore, the axis of the first support frame 25 can swing with a spacing corresponding to it as the center. Accordingly, if a strong wind that rotates the first support frame 25 in the axial direction of the first support frame 25 occurs, an excessive load acts on the limiting protrusion 17, which may damage the limiting protrusion 17 or the ball 10. In this case, the movable plate 21 combined with the limiting protrusion 17 slides, thereby alleviating its impact. On the other hand, if the movable plate 21 slides, the movable plates 21 located on both sides of the ball 10 slide in the same direction. Then, the movable plate 21 slides in the circumferential direction of the ball 10. Accordingly, even if the movable plate 21 slides, the limiting protrusions 17 located on both sides of the ball 10 will be spaced at a predetermined spacing. Therefore, the limiting protrusion 17 will not escape from the guide groove 11 of the ball 10.

[0062] On the other hand, in order to set up and disassemble the floating water support device, the first support frame 25 should be rotated and raised to the floating part 16. At this time, the first support frame 25 should be rotated so that the submerged part of the first support frame 25 immersed in the water rises between the cutouts 16b of the floating part 16. Therefore, the first support frame 25 should be limited to rotate only around one axis. In this case, it is also necessary to rotate the limiting protrusion 17 to move forward further. In this way, the limiting protrusion 17 is rotated and inserted into the inside of the fixing groove 13. According to this, the ball 10 is restricted from rotating in other directions and can only rotate around the axis of the limiting protrusion 17. Therefore, the first support frame 25 can be easily rotated and raised to the floating part 16.

[0063] According to this, in this embodiment, since the guide groove 11 is formed in the ball 10 and the limiting protrusion 17 is inserted into the guide groove 11, the rotation around the axis of the first support frame 25 can be limited. Therefore, if a wind turbine generator or the like is provided on the first support frame 25, the axis of the wind turbine generator can be prevented from rotating due to wind. Of course, in this case, the rotatable movable plate 21 can move in the circumferential direction of the ball 10.

[0064] Furthermore, in order to prevent the first support frame 25 from rotating about its axis, the limiting protrusion 17 inserted into the guide groove 11 can move left and right together with the movable plate 21 within a predetermined pitch range, so even if an excessive load acts, the impact can be mitigated.

[0065] In addition, the limiting protrusion 17 can be inserted into the fixing groove 13 of the ball 10, so the ball 10 is limited to rotate only in the axial direction of the limiting protrusion 17. Therefore, the first support frame 25 can be easily raised to the floating part 16.

[0066] Figure 6 It is another embodiment of the floating water support device of the present invention. Figure 6 An example is in Figure 1The embodiment further includes a blocking cover 40. The blocking cover 40 is installed on the floating part 16 to prevent water from flowing into the ball 10. The blocking cover 40 can be installed only on the lower part of the floating part 16 or on both the upper part and the lower part of the floating part 16 to prevent water from flowing into the ball 10. The blocking cover 40 can be formed of a soft material that can be deformed when the floating part 16 shakes.

[0067] Figure 7 These are other embodiments of the floating water support device of the present invention. Figures 1 to 4 In the embodiment, the floating portion 16 is composed of a plate, so the other end of the first support frame 25 is immersed in water, but Figure 7 In an embodiment, the floating part 16 is a hollow shell so that the other end of the first support frame 25 is accommodated inside. Even if the floating part 16 is shaken by waves when wave activity occurs, the first support frame 25 should not be affected by the waves. In this case, the other end of the first support frame 25 is accommodated inside the floating part 16 and is completely unaffected by the waves, so the first support frame 25 can be kept vertical more safely.

[0068] Figure 8 These are other embodiments of the floating water support device of the present invention.

[0069] Figures 1 to 4 The embodiment has a limiting protrusion 17 and a fixing member 20 for limiting the rotation of the ball 10. Figure 8 In another embodiment, the limiting protrusion 18 is formed into a ball shape and inserted into the guide groove 11 to limit the rotation of the ball 10. In this case, the fixing groove 13 is not required in the ball 10, but a groove that can accommodate the limiting protrusion 18 is formed in the floating part 16. Since the limiting protrusion 18 is accommodated in the floating part 16, the fixing member 20 is also unnecessary. On the other hand, in order to reduce the friction between the ball 10 and the floating part 16, the bearing 19 supporting the ball 10 can be installed in the floating part 16.

[0070] Fig. 9 and Fig.10 These are other embodiments of the floating water support device of the present invention.

[0071] The floating water support device of the present invention comprises a floating tool, a support tool 60 and a mounting seat 70 .

[0072] The floating tool has a floating portion 51, and the floating portion 51 is the same as that in the above-described embodiment.

[0073] The supporting tool 60 has a coupling frame 61 and a second supporting frame 63, and is installed on the floating part 51. The coupling frame 61 is composed of a support plate 61a at the upper end and coupled to the floating part 51, and the lower end can be coupled to the second supporting frame 63 through a universal joint. The upper end of the second supporting frame 63 is coupled to the lower end of the coupling frame 61 through a universal joint. Therefore, the coupling frame 61 can rotate forward, backward, left, and right relative to the second supporting frame 63. The lower end of the second supporting frame 63 is heavier than the upper end. Therefore, the second supporting frame 63 should always be vertically erected.

[0074] The mounting seat 70 is exposed to the upper part of the floating tool so that a structure such as a wind turbine generator can be installed on the upper part, and is connected to the second support frame 63 through a through hole passing through the center of the floating part 51. Accordingly, the mounting seat 70 is integrated with the second support frame 63, so that the same angle as the second support frame 63 can be maintained. Therefore, if the second support frame 63 is erected, the mounting seat 70 will also be erected.

[0075] In the present embodiment, the coupling frame 61 is coupled to the second support frame 63 via a universal joint, so the coupling frame 61 can rotate forward and backward or left and right relative to the second support frame 63. Fig.10 As shown, the floating part 51 sways forward and backward or left and right. Even if the floating part 51 sways forward and backward or left and right, the lower end of the second support frame 63 is heavy, so the second support frame 63 will stand vertically and will not sway forward and backward or left and right. Therefore, in the case of this embodiment, the mounting base 70 is also vertically erected, so if the wind turbine is installed on the mounting base 70, it can be kept vertical without being affected by waves.

[0076] Fig.11 These are other embodiments of the floating water support device of the present invention.

[0077] Fig.11 The illustrated embodiments and Figure 7 The same as the embodiment, in Fig. 9 In the embodiment, the upper floating portion 52 is formed by a hollow shell to surround the second supporting frame 63 .

[0078] in addition, Figures 7 to 11 The same is true for the embodiment of Figure 6 A blocking cover 40 may be installed.
