[0002] A floating dock is an engineering vessel used for ship repair and shipbuilding. The floating dock has a special structure, with a huge concave-shaped cabin, walls on both sides, and open front and rear ends. It is a special trough-shaped flat-bottomed ship. The walls on both sides and the bottom of the dock are box-shaped structures, which are divided into several closed compartments along the longitudinal and transverse directions. Some compartments are called water tanks, which are used to fill and drain water to make the dock sink and float. In addition to ensuring buoyancy, the bottom tank can also support the ship.

[0003] During the operation of the floating dock, ships need to enter and exit the floating dock from land for construction or repair. However, the elevation height of the land dock and the water depth of the dock area are limited. In some cases, the floating dock needs to be raised so that its pontoon deck is flush with the land dock to ensure that ships can be safely pulled in and out of the floating dock.

[0036] Reference below Figure 1-Figure 6 The freeboard structure of a floating dock raising pontoon according to an embodiment of the utility model is described.

[0037] like Figure 1-Figure 6 As shown, the floating dock pontoon freeboard raising structure is mainly used in the floating dock 100 structure. The conventional process of ships entering the floating dock 100 only focuses on the operation function of the ship entering and exiting the floating dock 100 in the water area, while ignoring the consideration of pulling and moving in and out of the floating dock 100 in the land dock stage during the ship construction and repair process. The utility model designs a floating dock 100 freeboard raising structure, adopts a basin-shaped structure to provide a safe and efficient ship entering and exiting the floating dock 100 structure in the land stage, facilitates the renovation and construction of the floating dock 100, and has low cost and efficient construction.

[0038] Specifically, the floating dock 100 includes a boat lift deck 110, a dock wall 120, a dock door 200 and a dock pier 130. The boat lift deck 110 is arranged at the bottom of the floating dock 100, and dock walls 120 are arranged on both sides of the boat lift deck 110, and the dock walls 120 and the boat lift deck 110 constitute the main structure of the floating dock 100.

[0039] The boat-lifting deck 110 and the dock wall 120 are combined to form the concave structure of the existing floating dock 100, which has the designed rated buoyancy. In order to further increase the freeboard height of the floating dock 100, dock gates 200 are arranged at the front and rear ends of the boat-lifting deck 110. The bottom of the dock gate 200 is connected to the boat-lifting deck 110, and the two sides of the dock gate 200 are respectively connected to the dock wall 120. The dock gate 200, the boat-lifting deck 110 and the dock wall 120 form a closed basin structure. The dock gate 200 can increase the buoyancy reserve of the floating dock 100, so that the part above the boat-lifting deck 110 of the floating dock 100 forms a closed basin structure, providing additional buoyancy for the floating dock 100.

[0040] The dock 130 is arranged on the surface of the ship lifting deck 110, and the dock 130 is used to support the bottom of the ship. When the ship enters the floating dock 100 and lands on the floating dock 100 ship lifting deck 110, the bottom support of the ship is supported by the dock 130. Among them, the height of the dock door 200 is lower than the height of the dock 130.

[0041] In this embodiment, the height of the dock 130 is H1, the height of the boat-lifting deck 110 at the bottom of the floating dock 100 is H, the inner distance of the dock walls 120 on both sides, i.e., the width, is B, the height of the dock gate 200 is h, and the distance between the dock gates 200 at both ends is L. The extra buoyancy provided by the basin-shaped structure formed by the connection of the floating dock 100 with the dock gates 200 displaces a liquid volume of L*h*B, which can significantly increase the freeboard height of the floating dock 100.

[0042] The height H1 of the floating dock 100 pier 130130 is generally 1m to 2m, and the height h of the dock gate 200200 is less than H1.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the width of the dock door 200 is equal to the distance between the two dock walls 120. Specifically, the width of the dock door 200 is equal to the inner distance of the two dock walls 120, and the width is also B. The two sides of the dock door 200 are respectively welded to the inner wall of the dock wall 120 to form a sealed basin-shaped structure.

[0044] In some embodiments of the present invention, Figure 1 and Figure 2 Specifically, the height h of the dock door 200 is lower than the height H1 of the dock 130 , and the h value is equivalent to the freeboard increase value of the ship lifting deck 110 of the floating dock 100 on the basis of meeting the requirements of the classification society.

[0045] Furthermore, if Figure 1 and Figure 2As shown, the freeboard elevation value of the floating dock 100 is equal to the height value of the dock door 200. Specifically, after the portion above the ship lifting deck 110 of the floating dock 100 forms a closed basin-shaped structure, when a ship is pulled in and out of the floating dock 100 by the land dock, the floating dock 100 is lifted as a whole, and the ship lifting deck 110 is lifted accordingly, and the height of the lifting value is h.

[0046] In some embodiments of the present invention, Figure 3-Figure 6 As shown, the dock door 200 adopts a box structure, and the dock door 200 and the boat lifting deck 110 are connected to form a watertight box structure. Specifically, the dock door 200 is designed as a box structure, and the steel structure material is a combination of steel plates and profiles, and the materials are all of Class A material grade of the classification society CCS.

[0047] In some embodiments of the present invention, Figure 3-Figure 6 As shown, the dock door 200 includes a dock door panel 210 and a dock door belly plate 220. The dock door panel 210 is arranged on the top of the dock door 200. Both sides of the dock door panel 210 are respectively welded to the top of the dock door belly plate 220. The bottom of the dock door belly plate 220 is welded to the boat lifting deck 110 to form a sealed box inside the dock door 200. The bottom of the dock door belly plate 220 is welded and fixed to the boat lifting deck 110 to form a watertight structure at the bottom.

[0048] The height of the dock door web 220 is h, which is equal to the height of the dock door 200, the spacing b between the two dock door webs 220 is 0.8m to 1.5m, and the width of the dock door panel 210 is equal to the spacing between the two dock door webs 220. Avoid setting the dock door webs 220 too close to increase the weight of the dock door 200 or setting them too far to reduce the structural strength of the dock door 200.

[0049] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the inner walls of the dock panel 210 and the dock web 220 are provided with a plurality of dock ribs 230 , and the dock ribs 230 are used to strengthen the structural strength of the dock panel 210 and the dock web 220 , and the spacing between the dock ribs 230 is 0.5 mm to 0.8 mm.

[0050] Specifically, the dock door 200 adopts a transverse internal frame structure, which is composed of dock door ribs 230. The materials of the dock door ribs 230 are all of Class A material grade and profile structure specifications of the classification society CCS, and angle steel or bulb flat steel profiles are used.

[0051] In some embodiments of the present invention, Figure 4-Figure 6As shown, the dock door ribs 230 and the dock door ribs 240 are staggered inside the dock door 200. Specifically, the dock door ribs 240 and the dock door ribs 230 are interlaced inside the dock door 200 along the length extension direction of the dock door 200. The periphery of the dock door ribs 240 are welded and fixed to the dock door panel 210, the dock door web 220 and the ship lifting deck 110 respectively.

[0052] In some embodiments of the present invention, Figure 4-Figure 6 As shown, the thickness of the dock panel 210, the dock web 220, the dock rib 230 and the dock rib 240 is 6 mm to 8 mm.

[0053] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
