Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a fixed device for a floating dock and a floating dock system. Background Art

[0002] A floating dock is a rectangular flat-bottomed non-self-propelled ship without a power device, usually fixed on the shore as a "floating dock" for ships to dock, for passengers to board and alight, for loading and unloading goods, for refueling, etc. Floating docks are usually used for cargo loading, unloading and storage in inland rivers, rivers and seas or ports, and are also used as floating warehouses, floating office places or floating entertainment places, etc. Especially in recent years, with the rise of electric or other clean energy ships, the function of floating docks as berthing and charging and clean fuel supply has become more and more important.

[0003] In order to ensure the effective positioning of the floating dock, in the prior art, usually an anchor is thrown, and an anchor chain of sufficient length is thrown on the ship. The grip of the anchor claw on the bottom of the water and the friction between the anchor chain and the bottom of the water are used to resist the impact of the water flow on the floating dock. This method can only effectively position the floating dock in calm weather; or reliable fixing facilities such as mooring bollards and mooring rings are set on the shore, and then the floating dock is tied to these facilities through steel cables and anchor chains to resist the impact of the water flow. This fixing method is suitable for floating docks close to the shore and depends on a stable shore base, which has requirements for geographical location and tidal difference, and has a narrow scope of adaptation. In case of strong winds and waves, it may cause damage to the shore base and bring greater property losses; or a positioning pile or other methods are set to achieve the positioning of the floating dock. The floating dock positioning pile is fixed on the dock or in the water and installed in front of and behind the floating dock to fix the floating dock. This method still damages the shore base in waters with large tidal differences. In case of strong winds, waves and typhoons passing by, there may be a situation where the superstructure is slapped by the wind and waves, resulting in damage to the superstructure. Later maintenance will affect normal use. It can be seen that the positioning methods in the prior art cannot simultaneously solve the problems of positioning the floating dock in case of strong winds and waves, the requirements for the shore base and geographical location, and the damage to the superstructure caused by the slapping of the wind and waves in case of strong winds and waves.

[0004] Therefore, there is an urgent need for a fixed device for a floating dock and a floating dock system to solve the above problems. Summary of the Utility Model

[0031] Example 1

[0032] This embodiment provides a barge fixing device for fixing a barge. The barge includes a main hull 5 and a superstructure 6 detachably connected to the main hull 5. Even in strong winds and waves, the barge can be well positioned, and the position of the superstructure 6 relative to the main hull 5 can be adjusted to avoid damage to the superstructure 6 caused by the impact of wind and waves. At the same time, the positioning of the barge fixing device proposed in this embodiment does not rely on the shore base and is not affected by the geographical location.

[0033] As Figures 1-3 shown, the barge fixing device includes: a positioning pile 1, a support column 2, and a height adjustment mechanism (not shown in the figure). Specifically, the positioning pile 1 is vertically fixed to the bottom of the water and is used to position the main hull 5 in a first direction, and the first direction is perpendicular to the vertical direction. Specifically, the bottom end of the positioning pile 1 is fixed to the bottom of the water, and the top end of the positioning pile 1 can extend out of the water surface and is used to interfere with the main hull 5 in the first direction, so that the main hull 5 cannot move in the first direction. The main hull 5 is provided with a positioning space, and the positioning pile 1 can extend into the positioning space to achieve the positioning of the main hull 5. Optionally, one or more positioning piles 1 can be provided, and this embodiment does not limit this. As Figure 3 shown, two positioning piles 1 are provided, and the two positioning piles 1 are spaced apart in the first direction and are both in contact with the main hull 5 to limit the main hull 5 in the first direction.

[0034] The support column 2 linearly extends in the vertical direction. The bottom end of the support column 2 passes through the main hull 5 and is fixed to the bottom of the water, and the top end of the support column 2 passes through the superstructure 6, and the superstructure 6 is selectively connected to the support column 2; the height adjustment mechanism is connected to the superstructure 6 and is used to drive the superstructure 6 to move relative to the main hull 5.

[0035] By setting the positioning piles 1, one end of the positioning pile 1 is fixed to the bottom of the water, and the other end is connected to the main hull 5, thereby positioning the main hull 5 in the first direction. The bottom end of the support column 2 passes through the main hull 5 and is fixed to the bottom of the water, and the top end of the support column 2 passes through the superstructure 6. By setting the support column 2, the translation of the main hull 5 in the horizontal direction is restricted. Through the combined action of the positioning pile 1 and the support column 2, the rotation of the main hull 5 in the horizontal direction is also restricted, so that the main hull 5 can only move in the vertical direction, realizing the positioning of the main hull 5. The height adjustment mechanism can adjust the position of the superstructure 6 relative to the main hull 5, and the superstructure 6 can be connected to the support column 2, realizing the fixation of the superstructure 6, and thus realizing the positioning of the entire pontoon. Even in strong wind and wave conditions, the pontoon can be well positioned, avoiding the translation and rotation of the pontoon on the horizontal plane. At the same time, the height adjustment mechanism is connected to the superstructure 6 and is used to drive the superstructure 6 to move relative to the main hull 5, and the superstructure 6 is selectively connected to the support column 2, thereby realizing the position adjustment of the superstructure 6 relative to the main hull 5, and avoiding the situation that the superstructure 6 is damaged by the impact of wind and waves in strong wind and wave conditions.

[0036] As Figure 3 shown, further, there are two positioning piles 1. The pontoon fixing device further includes a first positioning structure 52 and a second positioning structure 53 arranged at one end of the main hull 5 in the length direction. The two positioning piles 1 are arranged at intervals in the first direction. The first positioning structure 52 and the second positioning structure 53 are arranged on the opposite sides of the two positioning piles 1 in the first direction. The first positioning structure 52 or the second positioning structure 53 is detachably connected to the main hull 5, and the superstructure 6 is arranged near the other end of the main hull 5 in the length direction. It can be understood that the first positioning structure 52 and the second positioning structure 53 are arranged at one end of the main hull 5 in the length direction and fixed on the positioning piles 1, restricting the movement of one end of the main hull 5 on the horizontal plane. The superstructure 6 is arranged near the other end of the main hull 5 in the length direction, and the support column 2 passing through the main hull 5 restricts the movement of the other end of the pontoon on the horizontal plane, thereby simultaneously limiting the movement of the pontoon on the horizontal plane at both ends of the pontoon, further improving the positioning effect of the pontoon on the horizontal plane. Even in strong wind and wave conditions, the pontoon can be well positioned, further improving its stability. Whether to specifically use the first positioning structure 52 or the second positioning structure 53 to be detachably connected to the main hull 5 can be determined according to the installation requirements, and this embodiment does not make any limitations in this regard.

[0037] Furthermore, the height adjustment mechanism includes a winch 3 and a steering member 4. The steering member 4 is rotatably arranged at the top end of the support column 2. The winch 3 is installed on the superstructure 6. The end of the cable 31 of the winch 3 bypasses the steering member 4 and is connected to the main hull 5 or the superstructure 6. It can be understood that when the end of the cable 31 of the winch 3 is connected to the main hull 5, the superstructure 6 and the main hull 5 are connected by the cable 31. When the end of the cable 31 of the winch 3 is connected to the superstructure 6, the cable 31 can be fixed on the superstructure 6 to prevent the cable 31 from interfering with other structures on the pontoon, damaging other structures or injuring the staff on the pontoon. Exemplarily, the steering member 4 is a fixed pulley, and the end of the cable 31 bypasses and abuts against the fixed pulley to change the movement direction through the fixed pulley, so as to realize the connection with the main hull 5 or the superstructure 6.

[0038] Optionally, the pontoon fixing device further includes a first fixing structure 61 arranged on the superstructure 6 and a second fixing structure 51 arranged on the main hull 5. The cable 31 includes a lifting state and a limiting state. When the cable 31 is in the lifting state, the end of the cable 31 is connected to the second fixing structure 51. When the cable 31 is in the limiting state, the end of the cable 31 is connected to the first fixing structure 61. It can be understood that when the cable 31 is in the lifting state, the end of the cable 31 is connected to the second fixing structure 51, that is, the end of the cable 31 is connected to the main hull 5. At this time, the cable 31 can be driven by the winch 3, specifically by winding up the cable 31, to realize the movement of the superstructure 6 relative to the main hull 5, and further realize the position adjustment of the superstructure 6 relative to the main hull 5. When the cable 31 is in the limiting state, the end of the cable 31 is connected to the first fixing structure 61, that is, the end of the cable 31 is connected to the superstructure 6. At this time, both the end of the cable 31 and the winch 3 are located on the superstructure 6, and the cable 31 can be fixed on the superstructure 6 to prevent the cable 31 from interfering with other structures on the pontoon, damaging other structures or injuring the staff on the pontoon. Exemplarily, both the first fixing structure 61 and the second fixing structure 51 are lashing eye plates, and the end of the cable 31 can be passed through the lashing eye plate and fixedly connected thereto.

[0039] Further optionally, the second fixing structure 51 is located on the top surface of the main deck of the main hull 5 or below the main deck of the main hull 5. It can be understood that when the second fixing structure 51 is located on the top surface of the main deck of the main hull 5, it is convenient to fix the second fixing structure 51 on the main deck of the main hull 5, and the operation is simple. When the second fixing structure 51 is located below the main deck of the main hull 5, the flatness of the main deck surface can be ensured.

[0040] In this embodiment, the second fixing structure 51 is arranged at one end of the main deck of the main hull 5 close to the positioning pile 1, so as to facilitate the connection between the mooring rope 31 and the second fixing structure 51, and avoid interference with the superstructure 6 when the mooring rope 31 is connected to the second fixing structure 51.

[0041] Optionally, a plurality of groups of support columns 2 and height adjustment mechanisms are provided in one-to-one correspondence, and the steering member 4 of the height adjustment mechanism is rotatably arranged at the top end of the corresponding support column 2. It can be understood that by providing a plurality of groups of support columns 2 and height adjustment mechanisms, the limiting effect on the main hull 5 can be improved. At the same time, when adjusting the position of the superstructure 6 relative to the main hull 5, there can be multiple force application ends and force receiving ends, which can drive superstructures 6 of different specifications. Moreover, since the driving ability of the height adjustment mechanism is limited, by providing a plurality of groups of support columns 2 and height adjustment mechanisms, when driving the superstructure 6, the force applied by each group of height adjustment mechanisms can be reduced, which is beneficial to extending the service life of the height adjustment mechanism.

[0042] Optionally, the plurality of groups of support columns 2 are respectively located at both ends of the superstructure 6 along its length direction and close to the ship's side. It can be understood that in the case of strong winds and waves, the superstructure 6, especially the parts at both ends along its length direction and close to the ship's side, will bear a large wave impact force. By arranging the plurality of groups of support columns 2 at this position respectively, a good positioning effect can be ensured, and there is no interference with the inside of the superstructure 6, and the layout is convenient.

[0043] Exemplarily, the support columns 2 and the height adjustment mechanisms can be provided in 2 groups, 3 groups, 4 groups, 5 groups, etc. in one-to-one correspondence. In this embodiment, as Figure 3 shown, the support columns 2 and the height adjustment mechanisms are provided in 3 groups in one-to-one correspondence, one of which is arranged at one end of the superstructure 6 along its length direction, and the other two are arranged at intervals in the width direction at the other end of the superstructure 6 along its length direction.

[0044] Furthermore, as Figure 2 shown, the support column 2 is provided with a fixing hole 21, and the pontoon fixing device further includes a limiting component 7. The limiting component 7 is arranged on the superstructure 6, and at least part of the limiting component 7 selectively passes through the fixing hole 21 and is used to fix the superstructure 6 to the support column 2. It can be understood that by providing the fixing hole 21 on the support column 2 and the limiting component 7 on the superstructure 6, and at least part of the limiting component 7 selectively passes through the fixing hole 21, the superstructure 6 is fixed to the support column 2 in this way, thereby improving the stability of the superstructure 6.

[0045] Optionally, a plurality of fixing holes 21 are provided at intervals along the axial direction of the support column 2, and at least part of the limiting component 7 selectively passes through any one of the fixing holes 21. It can be understood that by providing a plurality of fixing holes 21 at intervals along the axial direction of the support column 2, the superstructure 6 can be fixed at different positions of the support column 2, that is, the superstructure 6 can be fixed at different heights relative to the main hull 5. For different wind and waves, different heights can be selected, and the adaptability is relatively strong.

[0046] Optionally, the limiting component 7 includes a movable member 72 and two fixing plates 71 both arranged on the superstructure 6. Each fixing plate 71 is provided with a limiting hole (not shown in the figure), and the two fixing plates 71 are arranged on both sides in the radial direction of the support column 2. The movable member 72 can pass through the fixing hole 21 and the two limiting holes. It can be understood that when fixing the superstructure 6, the movable member 72 can pass through the fixing hole 21 and the two limiting holes at the same time, that is, the movable member 72 passes through the support column 2 and the two fixing plates 71 at the same time to limit the superstructure 6. The limiting effect is good, and at the same time of limiting the superstructure 6, it can also play a certain supporting role for the superstructure 6 to make the superstructure 6 more stable.

[0047] Furthermore, the limiting component 7 has a limiting state and a free state. When the limiting component 7 is in the limiting state, the movable member 72 passes through the fixing hole 21 and the two limiting holes at the same time to fix the superstructure 6 and limit the superstructure 6. When the limiting component 7 is in the free state, the movable member 72 is located outside the support column 2, and the movable member 72 does not interfere with the fixing hole 21, and the superstructure 6 can move radially along the support column 2 to adjust the position of the superstructure 6 relative to the main hull 5.

[0048] Exemplarily, the fixing plate 71 is a steel plate, vertically welded to the superstructure 6, and the movable member 72 is a bolt.

[0049] Furthermore, as Figure 1 and Figure 2As shown in the figure, the floating dock has a floating state and a separated state. In the case of no strong winds and waves, the floating dock is in the floating state, with less ballast water in the main hull 5. The buoyancy provided by the water surface to the main hull 5 ensures that the main hull 5 can float on the water surface. The end of the mooring rope 31 is connected to the first fixing structure 61 of the superstructure 6 to fix the mooring rope 31. At this time, the limiting component 7 is in a free state, and the movable part 72 is outside the support column 2, and the movable part 72 does not interfere with the fixing hole 21, so the floating dock can move freely in the height direction. In the case of strong winds and waves, the floating dock is in the separated state. At this time, there is more ballast water in the main hull 5, which can directly sink to the bottom of the water. The end of the mooring rope 31 is connected to the second fixing structure 51 of the main hull 5. The height adjustment mechanism drives the superstructure 6 to move relative to the main hull 5 to lift the superstructure 6 to an appropriate height. After the superstructure 6 is lifted to an appropriate height, the limiting component 7 is switched to the limiting state to position the superstructure 6.

[0050] It can be understood that in the separated state of the floating dock, after the main hull 5 sinks to the bottom of the water, it can ensure the positioning of the floating dock in the case of strong winds and waves. After the superstructure 6 is lifted, it can ensure that the superstructure 6 will not be affected by large waves. The limiting component 7 can position the lifted superstructure 6. The end of the mooring rope 31 is connected to the main hull 5. Since the main hull 5 is heavy, it can play a certain role in fixing the superstructure 6, so that the floating dock can be stably positioned in the case of strong winds and waves.

[0051] Embodiment 2

[0052] This embodiment provides a floating dock system, including a floating dock and the floating dock fixing device disclosed in Embodiment 1. Even in the case of strong winds and waves, it can better position the floating dock system.

[0053] The floating dock includes a main hull 5 and a superstructure 6 detachably connected to the main hull 5. The positioning pile 1 positions the main hull 5 in the first direction. The bottom end of the support column 2 passes through the main hull 5 and is fixed to the bottom of the water. The top end of the support column 2 passes through the superstructure 6, and the height adjustment mechanism is connected to the superstructure 6. It can be understood that: the positioning pile 1 positions the main hull 5 in the first direction, and the bottom end of the support column 2 passes through the main hull 5 and is fixed to the bottom of the water. Through the combined action of the positioning pile 1 and the support column 2, the entire floating dock can be positioned. The superstructure 6 is detachably connected to the main hull 5, and the main hull 5 can sink to the bottom of the water, which not only strengthens the positioning pile 1 but also reduces the acting force of the wind and waves on the main hull 5, thus avoiding the risk of blocking the waterway caused by the displacement of the main hull 5. At the same time, the height adjustment mechanism is connected to the superstructure 6 and can drive the superstructure 6 to move relative to the main hull 5 to realize the position adjustment of the superstructure 6 relative to the main hull 5, and can avoid the situation where the superstructure 6 is damaged by the impact of the wind and waves in the case of strong winds and waves.

[0054] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than a limitation on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here.
