[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0031] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] The utility model embodiment provides a water stop structure of a pontoon dock door, referring to Figure 1 As shown, an embodiment of the utility model provides a water-stop structure for a pontoon-type dock door, comprising: a pressure pad 10, a water-stop belt 20 and a pressure plate 30; in an optional embodiment, the water-stop belt 20 is made of chloroprene rubber; the pressure pad 10 is made of engineering plastic alloy; and the pressure plate 30 is made of nickel-chromium alloy.

[0035] The water stop 20 is located on the top of the pressure pad 10;

[0036] The water stop strip 20 includes an annular portion 21 , a connecting portion 22 and a strip portion 23 . The connecting portion 22 and the strip portion 23 are sequentially connected to one side of the annular portion 21 .

[0037] It is understandable that the water stop strip 20 made of chloroprene rubber is elastic and is an important component for the water stop structure 100 to achieve a water stop effect. It includes at least three parts: an annular portion 21, a connecting portion 22, and a strip portion 23. The connecting portion 22 is connected to both sides of the annular portion 21, and the strip portion 23 is connected to the side of the connecting portion 22 away from the annular portion 21. Generally speaking, the width of the strip portion 23 is greater than the width of the connecting portion 22.

[0038] Furthermore, the thickness of the connecting portion 22 is the same as the wall thickness of the annular portion 21 . The thickness of the strip portion 23 is greater than that of the connecting portion 22 . The strip portion 23 is provided with a notch 231 , and the thickness of the notch 231 is not less than that of the connecting portion 22 .

[0039] Furthermore, a pressure plate 30 is placed on the top of the connecting portion 22, and the pressure plate 30, the connecting portion 22 and the pressure pad 10 are fixed by a fixing assembly 40;

[0040] The strip portion 23 includes a plurality of notches 231 . The fixing assembly 40 fixes the strip portion 23 and the pressure pad 10 in any of the notches 231 .

[0041] It is understandable that the water stop 20 is arranged on the top of the pressure plate 10 and fixed by the fixing assembly 40. The pressure plate 10 can not only firmly fix the water stop structure 100 on the surface of the dock door 01, but also effectively adjust the flatness and fit of the water stop 20 to avoid the water stop 20 from shifting during the opening and closing process of the dock door 01, thereby causing the risk of water seepage.

[0042] Furthermore, a pressure plate 30 is provided at the connection portion 22. When the dock door 01 is closed, the water stop structure 100 is squeezed to close the gap between the dock door 01 and the dock pier 02 or dock sill 03, thereby achieving water stopping. Since the annular portion 21 of the water stop belt 20 is mainly subjected to force, a pressure plate 30 is provided on the connection portion 22 connected thereto to further fix the water stop belt 20 and ensure that the annular portion 21 will not be displaced.

[0043] In order to ensure the sealing effect of the waterstop structure 100, the accuracy requirements for the waterstop structure 100 are: the positive error of the surface of the pressure pad 10 does not exceed 2mm, the positive and negative errors of the verticality do not exceed 1mm, and the surface flatness error range of the waterstop belt 20 is ±2mm.

[0044] Further, the fixing assembly 40 is used to fix the water stop 20 and the pressure plate 10, as well as the pressure plate 30. Specifically, the fixing assembly 40 includes a bolt 41, a gasket 42 and a nut 43;

[0045] When the fixing assembly 40 is fixed to the connecting portion 22 of the water stop belt 20, the bolt 41 is screwed into the pressure plate 30, the connecting portion 22 and the pressure pad 10 in sequence, the gasket 42 is placed on the top of the pressure plate 30, and the nut 43 is tightened on the end of the bolt 41 facing away from the pressure pad 10.

[0046] When the fixing assembly 40 is fixed to the strip portion 23 of the water stop 20 , the bolt 41 is screwed into the strip portion 23 and the pressure pad 10 , the gasket 42 is placed on the top of the strip portion 23 , and the nut 43 is tightened on the end of the bolt 41 facing away from the pressure pad 10 .

[0047] It should be noted that the water stop structure 100 is disposed on the dock gate 01. Specifically, the pressure pad 10 of the water stop structure 100 is connected to the dock gate, and the water stop strip 20 points to the direction of the dock pier 02 and / or the dock sill 03. Figure 2 As shown, the water stop structure 100 includes several structures, all of which are arranged on the outer wall of the dock door 01 and arranged along the edge of the outer wall of the dock door 01. Specifically, the water stop structure 100 is arranged on the edge of the bottom of the outer wall of the dock door 01. The water stop structure 100 is arranged on the vertical edge of the outer wall of the dock door 01. Figure 3 and Figure 4 As shown, the dock door 01 is opened or closed by its own opening and closing system and with the help of an electric winch. The water stop structure 100 is arranged on the outer wall of the dock door 10. When the dock door 01 is closed with the dock pier 02 and the dock sill 03, the water stop strip 20 of the water stop structure 100 is closely attached to the pier 02 and the dock sill 03 by the water pressure on the sea side, effectively preventing seawater from entering or flowing out of the dry dock, and reducing the risk of water seepage in the dry dock door.

[0048] In order to further ensure the water-stopping and anti-seepage effect of the water-stop structure 100, the dock 02 and the dock sill 03 are respectively provided with a dock pier face and a sill protection block at a position opposite to the water-stop structure 100. The installation flatness error range of the dock pier face and the sill protection block is ±2mm. Combined with the high-precision water-stop structure 100, the tightness of the water-stop structure 100 and the dock pier 02 and the dock sill 03 can be effectively improved, thereby ensuring the water-stopping and anti-seepage effect. At the same time, along any edge of the outer wall of the dock gate 01, several water-stop structures 100 are arranged in parallel. The water-stop structure 100 may include two or more water-stop structures arranged in parallel, so as to improve the overall water-stopping and anti-seepage effect of the dock gate 01.

[0049] In summary, the water-stopping structure of the pontoon-type dock door provided by the utility model achieves at least the following beneficial effects:

[0050] In the embodiment provided by the utility model, the water stop is fixed on the pressure plate by means of a pressure plate and a fixing assembly, and the pressure plate is fixed on the dock door. After the dock door is installed and closed, the pressure of the seawater outside makes the water stop fit tightly with the dock pier and the dock sill, isolates the seawater, and achieves the water-stopping and anti-seepage effect of the dock door.
