DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figure 1 to Figure 8 As shown, a buffer-type dock structure includes a shore base, a primary buffer mechanism and a secondary buffer mechanism. The primary buffer mechanism is arranged on the side of the shore base close to the sea water and protrudes outward from the outer side of the shore base close to the sea water. The secondary buffer mechanism is arranged inside the shore base, closely attached to the primary buffer mechanism, and located on the side of the primary buffer mechanism close to the land.

[0026] It can be understood that when the ship docks, it first contacts the primary buffer mechanism at the initial speed, and the primary buffer mechanism further acts on the secondary buffer mechanism under the squeeze of the ship, further reducing the speed of the ship.

[0027] In this embodiment, multiple layers of carrying platforms 3 are arranged from bottom to top inside the shore base, and the top plate of the shore base is a shore sidewalk 1; the first-level buffer mechanism includes multiple anti-collision flattened balloons 4 and multiple first-level buffer balloons 9, and multiple anti-collision flattened balloons 4 are arranged at intervals on the side of the shore sidewalk 1 close to the sea water, and multiple first-level buffer balloons 9 are divided into multiple groups and are respectively embedded and fixed on a layer of carrying platforms 3. In each group, multiple first-level buffer balloons 9 are arranged at intervals in the length direction of the carrying platform 3 on the side of each layer of carrying platforms 3 close to the sea water; the secondary buffer mechanism is located on each layer of carrying platforms 3, and is located on the side of the first-level buffer balloons 9 close to the land.

[0028] The anti-collision flattening balloon 4 is composed of a tire-shaped body 401 and two circular parts 402. The circular parts 402 are arranged on the two circular sides of the tire-shaped body 401 respectively. The outer contours of the two circular parts 402 are located on the same circle and are arranged concentrically with the tire-shaped body 401. A plurality of deflation areas 5 are arranged at intervals on the circumferential side of the tire-shaped body 401. The central axis of the anti-collision flattening balloon 4 is arranged perpendicular to the side of the shore where it is located. In this embodiment, the tire-shaped body 401 and the two circular parts 402 are integrally formed. Of course, in other embodiments, the tire-shaped body 401 and the two circular parts 402 can also be a split structure connected to each other.

[0029] The primary buffer balloon 9 includes a hollow buffer sphere 10, and a plurality of deflation areas 5 are evenly distributed on the outer wall of the hollow buffer sphere 10. The side of the hollow buffer sphere 10 close to the water surface protrudes outside the shore base; a plurality of freely movable sand balls 11 are placed inside the hollow buffer sphere 10. In this embodiment, a shore base side plate 21 is provided between the shore base sidewalk 1 and the loading platform 3, and an opening 211 is provided on the shore base side plate. The diameter of the opening is smaller than the diameter of the hollow buffer sphere 10, and the center point of the opening is located on the same horizontal line as the center of the hollow buffer sphere 10. The portion of the hollow buffer sphere 10 protruding from the shore base side plate passes through the opening, and the diameter of the opening is the same as the maximum longitudinal section diameter of the portion of the hollow buffer sphere 10 protruding from the shore base side plate.

[0030] Of course, in other embodiments, the primary buffer balloon 9 may also be fixedly connected to the shore in other forms, for example, the upper and lower parts of the primary buffer balloon 9 may be fixedly connected to the carrying platform 3 and / or the shore-based sidewalk 1.

[0031] It can be understood that when the ship docks, it comes into contact with the primary buffer balloon 9 and the anti-collision flattened balloon 4, and the buffer balloon and the anti-collision flattened balloon 4 begin to deflate and deform, increasing the contact area between the balloon and the hull, and gradually converting the force into kinetic energy and potential energy. The anti-collision flattened balloon 4 transfers the force to the base shore, the primary buffer balloon 9 is deformed, and the sand ball 11 inside rolls and moves inward as a whole. The inner side of the primary buffer balloon 9 comes into contact with the secondary buffer mechanism, thereby achieving the purpose of protecting the dock and the hull.

[0032] Furthermore, a plurality of embedded rolling balls 7 are evenly arranged on the outer surfaces of the two circular portions 402, and the embedded rolling balls 7 are embedded and connected to the circular portions 402; pull rings 20 are provided on opposite sides of two adjacent anti-collision flattening balloons 4, and the two pull rings 20 are connected by a nylon rope 7; a plurality of embedded rolling balls 7 are also provided on the outer surface of the hollow buffer sphere 10, and the plurality of embedded rolling balls 7 and the plurality of deflation areas 5 are evenly distributed.

[0033] It is understandable that when the ship floats while docked, the hull contacts the embedded rolling ball 7 on the primary buffer bladder 9 and the anti-collision flattening bladder 4, and the embedded rolling ball 7 rolls with the floating hull, thereby achieving the purpose of protecting the hull structure and the outer surface paint.

[0034] In some embodiments, on the hollow buffer sphere 10, the plurality of embedded rolling balls 7 and the plurality of air release areas 5 are distributed on a plurality of outer circular lines of the hollow buffer sphere 10, and the embedded rolling balls 7 and the air release areas 5 on the same outer circular line are alternately arranged at equal intervals.

[0035] Of course, in other embodiments, the plurality of embedded rolling balls 7 and the plurality of air release areas 5 may also be evenly distributed on the hollow buffer sphere 10 in other forms.

[0036] In this embodiment, the shore foundation also includes a plurality of piles 2, which are arranged in two rows on the front and rear sides of the length direction of the shore foundation. The upper ends of the piles 2 are fixedly connected to the shore foundation sidewalk 1 after passing through multiple layers of carrying platforms 3 in sequence from bottom to top. The plurality of piles 2 in each row are arranged at intervals, and each of the first-level buffer balloons 9 is located between two adjacent piles 2.

[0037] It can be understood that, on the one hand, the plurality of piles 2 are used to form a supporting frame for the shore foundation, and on the other hand, placing the primary buffer balloon 9 between two adjacent piles 2 can limit the left and right positions of the primary buffer balloon 9 in the length direction of the shore foundation.

[0038] Furthermore, the degassing area 5 is circular, the diameter of the degassing area 5 is the same as the diameter of the embedded ball 7, the degassing area 5 is made of high elastic rubber 6, wherein the diameter of the central circular hole of the degassing area 5 is 1 / 3-1 / 2 of the diameter of the degassing area 5.

[0039] It is understandable that if Figure 8 As shown, in the static state, the internal and external pressures of the anti-collision flattening balloon 4 and the hollow buffer sphere 10 are balanced. When the anti-collision flattening balloon 4 and the hollow buffer sphere 10 are subjected to external pressure, the internal pressure increases, the diameter of the central circular hole in the deflation area 5 gradually increases, and the flow rate gradually increases, so that the buffer balloon gradually deforms, thereby achieving the purpose of protecting the dock.

[0040] In this embodiment, the secondary buffer mechanism includes a buffer water tank 12, and the buffer water tank 12 is provided with an opening on one side surface close to the primary buffer balloon 9, and the opening is blocked by a rubber film 13. Water 15 is filled in the buffer water tank 12, and an air vent 17 and a water injection hole 18 are provided on the top plate of the buffer water tank 12. A drain valve 19 is connected to the lower part of the side wall of the buffer water tank 12, and a limiting member is fixed on the inner wall of the buffer water tank 12 located on the outer peripheral side of the rubber film 13. The longitudinal section of the limiting member is an isosceles trapezoid, and the large bottom end of the limiting member is fixedly connected to the inner wall of the buffer water tank 12. Specifically, the limiting member is a circular flat iron 14 whose inner diameter and outer diameter gradually decrease from bottom to top. Of course, in other embodiments, the limiting member may also be of other structural forms, such as a plurality of inclined flat iron blocks arranged evenly in a circle.

[0041] It can be understood that when the ship docks, the ship contacts the primary buffer balloon 9, the primary buffer balloon 9 is deformed, the sand ball 11 inside rolls and moves inward as a whole, the inner side of the primary buffer balloon 9 contacts the rubber film 13, the water 15 in the water tank shakes, and the water 15 in the buffer water tank 15 hits the side wall and then moves in the opposite direction and hits the rubber film 13, the rubber film 13 hits the primary buffer balloon 9, and the primary buffer balloon 9 hits the hull, and the buffering process ends, achieving the purpose of protecting the dock and the hull; the setting of the limiter can guide and limit the squeezed rubber film 13, provide protection for the rubber film 13, limit the maximum squeezing degree of the balloon, and protect the film from rupture.

[0042] In this embodiment, the rubber film 13 is circular. When the radius of the rubber film 13 is too small, the secondary buffer mechanism cannot perform buffering well. When the rubber film 13 is too large, the entire primary buffer balloon 9 will be squeezed into the water tank 15 of the secondary buffer mechanism. Setting the radius of the rubber film 13 to between 1 / 2-2 / 3 of the radius of the primary buffer balloon 9 can effectively avoid the above two problems. In this embodiment, the radius of the rubber film 13 is 1 / 2 or 2 / 3 of the radius of the primary buffer capsule. Of course, in other embodiments, it can be set to other values ​​according to the situation; the water 15 in the buffer water tank 12 is located at 1 / 2-2 / 3 of its height.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications and substitutions may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
