Description

Technical Field

[0001] The utility model relates to the technical field of offshore equipment structures, and particularly relates to a dock gate sealing structure. Background Art

[0002] In the past, hardwood soaked with hemp ropes was commonly used for water sealing of traditional dock gates. However, due to its poor effect and short service life, it has gradually been abandoned. Later, rubber sealing materials were used for water sealing. Rubber water sealing materials have the characteristics of soft structure, good water sealing effect, easy processing and forming, etc., so they are often used in modern offshore equipment for water sealing.

[0003] Existing rubber water seals are divided into types such as triangular, P-shaped, and T-shaped according to their cross-sectional shapes. At the same time, most of the existing dock gate sealing structures use a single P-shaped water seal or triangular water seal for water sealing. When there are impurities such as floating objects, floating logs, and garbage in the water near the dock, they are likely to enter and get stuck between the dock gate water seal and the sealing surface, thereby damaging the water seal, causing the dock gate to leak water, and resulting in unnecessary economic losses. Summary of the Utility Model

[0041] Embodiment

[0042] Combined with Figure 1 And Figure 3 In this embodiment, a dock door sealing structure is provided, including: a first seal 1, which is installed on the dock side of the dock door body 2 in the working state, and the first seal 1 is used to seal the gap between the side wall of the dock door body 2 and the sealing surface of the dock entrance structure 4; a second seal 3, which includes a water seal section 3a and an installation section 3b connected to each other. The installation section 3b is installed on the water-facing side of the dock door body 2 in the working state, and the installation section 3b can seal the gap between the water seal section 3a and the dock door body 2; wherein, in the installed state, the water seal section 3a always abuts against the sealing surface of the dock entrance structure 4.

[0043] It should be understood that the existing dock door mechanism also includes a dock door body 2 and a dock entrance structure 4. The dock entrance structure 4 is usually a reinforced concrete structure and is arranged in a U shape, including structural types such as a bottom sill and side sills. The bottom sill in the dock sill is horizontally arranged at the entrance of the dry dock, and the side sills are arranged on both sides of the dock entrance. The dock door body 2 is a welded steel structure, and its length covers the entire dock entrance area, slightly larger than the dimensions of the dock sill and side sills.

[0044] In this embodiment, sealing plates 10 are provided on both the side sill and the bottom sill of the dock entrance structure 4, and the sealing surface is the side surface of the sealing plate 10 facing the dock. Generally speaking, on the side sill and the bottom sill of the dock entrance structure 4, stainless steel plates are embedded for bearing the horizontal thrust of the dock door and providing a water-stop contact surface. That is, the sealing plate 10 is a stainless steel plate, and of course, other corrosion-resistant and high-strength materials can also be used to make the sealing plate 10. Similarly, the sealing plate 10 is arranged in a U shape.

[0045] Among them, the sealing plate 10 not only needs to be in close contact with the first seal 1 and the second seal 3 to achieve the effect of water stoppage, but also needs to be in contact with the corresponding component on the dock gate body 2 (the water seal mounting seat 5) to transmit the load borne by the dock gate. In this regard, on the other side of the sealing plate 10 in this embodiment, embedded connecting ribs 11 are provided. The embedded connecting ribs 11 are embedded in the dock structure 4 to ensure that there is sufficient connection strength between the sealing plate 10 and the dock structure 4. The embedded connecting ribs 11 are usually in the shape of a bracket and are welded to the sealing plate 10. Of course, connecting ribs with other structural forms and other fixed connection methods can also be used.

[0046] Combined with Figure 2 , the first seal 1 is a triangular water seal to ensure that the first seal 1 can be reliably sealed.

[0047] It can be understood that the triangular water seal is usually made of rubber, its cross-section is similar to a triangle, and there are rounded corners at the three corners. The entire dock gate is arranged with a triangular water seal using 1 first seal 1.

[0048] Combined again with Figure 1 and Figure 2 , this embodiment further includes a water seal mounting seat 5. The water seal mounting seat 5 is installed on the dock side of the dock gate body 2 in the working state; a sealing groove 5a is provided on the dock side of the water seal mounting seat 5, and the first seal 1 is installed in the sealing groove 5a to facilitate the installation of the first seal 1 on the dock gate body 2.

[0049] In this embodiment, the water seal mounting seat 5 is made of ultra-high molecular weight polyethylene. It can be known that the existing water seal mounting seat 5 usually uses hardwood. However, hardwood has characteristics such as water absorption and expansion, poor compressive capacity, and short service life. The water seal mounting seat 5 made of polyethylene material has good heat resistance, does not absorb water, high strength, etc., strong compressive capacity, is not affected by water flow, and has a long service life.

[0050] Among them, the sealing groove 5a is a dovetail groove to ensure the stability of the installation of the first seal 1.

[0051] On this basis, the notch of the sealing groove 5a is chamfered to store the deformation amount after the first seal 1 is compressed through the chamfer of the notch of the sealing groove 5a. Thus, after the first seal 1 is in contact and pressed against the sealing surface of the dock structure 4, the first seal 1 completely enters the installation groove 2a, and its top plane always remains flat without protrusion, thereby ensuring the sealing ability of the first seal 1.

[0052] It should be understood that an installation groove 2a is provided on the dock side of the dock gate body 2, and the water seal mounting seat 5 is fixedly installed in the installation groove 2a to facilitate the installation of the water seal mounting seat 5.

[0053] Correspondingly, this embodiment further includes a first fixing bolt 6, and the first fixing bolt 6 is used to fixedly connect the water seal mounting seat 5 to the dock gate body 2 to ensure the stability of the installation of the water seal mounting seat 5.

[0054] Correspondingly, the water seal mounting seat 5 is provided with a bolt hole, the bolt hole is a countersunk hole, and the first fixing bolt 6 is inserted into the bolt hole.

[0055] In this embodiment, a sealing plug 7 is adapted to the countersunk end of the bolt hole to protect the first fixing bolt 6 and prevent the first fixing bolt 6 from being eroded by water flow.

[0056] Meanwhile, an epoxy sealing layer 2b is provided in the installation groove 2a, and the epoxy sealing layer 2b is used to bond the corresponding side wall of the water seal mounting seat 5, so as to facilitate the fixation of the water seal mounting seat 5 and prevent water from seeping between the water seal mounting seat 5 and the side wall of the installation groove 2a.

[0057] That is to say, the epoxy sealing layer 2b is located at the gap between the dock gate body 2 and the water seal mounting seat 5 and wraps the water seal mounting seat 5 on three sides. On the one hand, it bonds and fixes the water seal mounting seat 5, and on the other hand, it fills the gap to prevent water seepage. For the epoxy sealing layer 2b, a two-component epoxy filler is usually used for support, and the filling work needs to be carried out by pouring after the installation and adjustment of the water seal mounting seat 5 are completed.

[0058] It should be noted that when the dock gate body 2 is closed, the triangular water seal is compressed and all squeezed into the installation groove 2a, and the front end is in surface contact with the stainless steel sealing plate 10 to achieve the water stop effect. And this water seal is the main water seal of the dock gate, and its water stop effect is directly related to the water stop effect of the entire dock gate.

[0059] Combined with Figure 3 , the second sealing member 3 is a P-shaped water seal to ensure that the second sealing member 3 can achieve the effects of sealing and blocking debris. Similarly, the second sealing member 3 is a water seal formed by processing ethylene propylene diene monomer rubber through processes such as rubber mixing and vulcanization, and its P head (water seal section 3a) is solid and without holes.

[0060] This embodiment further includes a mounting pressing plate 8, and the mounting pressing plate 8 is used to press and attach the mounting section 3b to the water-facing side of the dock gate body 2. On the one hand, the gap between the mounting section 3b and the dock gate body 2 is filled to prevent leakage, and on the other hand, it can protect the second sealing member 3 from the tangential force during installation and avoid damage to the second sealing member 3 during the installation process.

[0061] It can be known that this embodiment further includes a second fixing bolt 9, and the second fixing bolt 9 is used to fix the mounting pressing plate 8 to the water-facing side of the dock gate body 2 to facilitate the fixation of the second sealing member 3 and the mounting pressing plate 8.

[0062] Meanwhile, a plurality of mounting through-holes are provided at intervals along the length directions of the mounting pressing plate 8 and the mounting section 3b, and the rod portions of the second fixing bolts 9 can pass through the mounting through-holes. That is to say, there are several fixing holes (with a spacing of 300 - 600 mm, such as 500 mm) on the mounting section 3b, and they are installed corresponding to the second fixing bolts 9.

[0063] Among them, the mounting through-holes on the mounting pressing plate 8 are long strip holes extending along the length direction of the mounting pressing plate 8 to ensure that the second fixing bolts 9 can correspond to the mounting through-holes on the mounting section 3b one by one.

[0064] Thus, the second seal 3 is fixed on the dock gate body 2 through the second fixing bolts 9 and the mounting pressing plate 8, and a certain design torque is applied to the second fixing bolts 9 to ensure the sealing performance. The second seal 3 has a corresponding compression amount (4 - 6 mm, such as 5 mm). When the dock gate is being closed from the open state, the water seal section 3a of the second seal 3 is gradually loaded and pressed, reaching the designed compression amount. When it is fully closed, the compression amount is the largest. At this time, the P-shaped head of the second seal 3 turns outwards and keeps in close contact with the sealing surface under the action of water pressure and its own elastic deformation pressure, playing a role in stopping water.

[0065] In summary, for the dock gate sealing structure provided in this embodiment, the first seal 1 is installed on the side of the dock gate body 2 facing the dock in the working state to seal the gap between the side wall of the dock gate body 2 and the sealing surface of the dock structure 4, playing a main sealing role. The second seal 3 includes a connected water seal section 3a and a mounting section 3b. The mounting section 3b is installed on the side of the dock gate body 2 facing the water in the working state, and the mounting section 3b can seal the gap between the water seal section 3a and the dock gate body 2 to prevent water from seeping in between the second seal 3 and the dock gate body 2. In the installation state, the water seal section 3a always abuts against the sealing surface of the dock structure 4, so that the second seal 3 plays an auxiliary sealing role.

[0066] Meanwhile, the mounting section 3b is installed on the side of the dock gate body 2 facing the water in the working state. In the installation state, the water seal section 3a always abuts against the sealing surface of the dock structure 4, so that the water seal section 3a extends to the side of the dock gate body 2 facing the dock, which can prevent floating objects and garbage outside the dock from mixing into the sealing surface and damaging the sealing surface and the first seal 1.

[0067] In addition, in this embodiment, the triangular water seal seat plate abandons the traditional hard wood material and adopts a high molecular weight PE material, avoiding the disadvantages of hard wood being fragile and swelling when absorbing water. And the dovetail groove structure is used to install and fix the triangular water seal, which can effectively ensure its installation accuracy. When the triangular water seal bears pressure, the reserved chamfered area can better absorb the expansion amount and ensure the flatness of the sealing surface of the entire PE seat plate.

[0068] Moreover, all hydraulic loads are borne by the gate body and the water seal mounting seat 5. The P-type water seal and the triangular water seal only serve the function of water stop, which can greatly reduce the loads on the water seal and extend the service life of the water seal.

[0069] In summary, the dock gate sealing structure provided by this embodiment can reduce the entry of debris between the dock gate water seal and the sealing surface, thereby improving the service life of the sealing member. At the same time, a double-layer seal is provided, with good sealing performance, thus improving the water stop efficiency and safety factor of the dock gate sealing structure.

It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention.
