Description

Technical Field

[0001] This invention relates to the field of lock technology, specifically to a lock miter gate water-stopping system. Background Technology

[0002] The upper and lower ends of the gate leaf of the miter gate are fixed by a top pivot device and a bottom pivot device, respectively, which allows the gate leaf to rotate normally to open and close the miter gate. Since the miter gate needs to block the water flow on both sides when closed, sufficient sealing is required between the miter gate and the gate head, as well as between the two gate leaves, to prevent water leakage under the action of water pressure difference on both sides.

[0003] Currently, sealing structures are in place to prevent water leakage between the gate leaf near the rotation axis and the upper seat assembly of the lock head, between the bottom of the gate leaf and the bottom surface of the lock head, and between the two gate leaves. However, there is little attention paid to sealing the gap between the bottom pivot assembly and the gate leaf. The bottom pivot assembly of the miter gate in a lock is generally made of cast steel or forgings, consisting of a bottom pivot seat, mushroom head pad, mushroom head, ball bearing, and bearing housing. These components are assembled sequentially and then connected to the bottom plate of the gate leaf using high-strength bolts. However, because the bearing housing and gate leaf of the bottom pivot assembly are installed as a unit, leakage or water jetting between them is unavoidable. This leakage or water jetting can cause corrosion of the bearing housing mating surface and fastening bolts, which can negatively impact the service life and safe operation of the lock.

[0004] In summary, there is an urgent need for a miter gate water-stopping system for ship locks to solve the problems existing in the current technology. Summary of the Invention

[0042] To facilitate understanding of the present invention, a more complete description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] Example:

[0045] This embodiment provides a miter gate water-stopping system for a ship lock. The structure of the ship lock is based on existing technology. For ease of understanding, the structure of the ship lock will be briefly described here first.

[0046] like Figure 1 and Figure 2 As shown, the lock includes a lock head 100 and a V-shaped gate. The V-shaped gate includes two gate leaves 200. The upper end of the gate leaf 200 is installed by a top pivot device 400 set on the lock head, and the lower end is installed by a bottom pivot device 300 set on the lock head. The top pivot device 400 and the bottom pivot device 300 can realize the rotation of the gate leaf 200 around the rotation axis 500, thereby realizing the opening and closing of the V-shaped gate.

[0047] The bottom pivot device 300 generally includes a bearing nest 310, a bottom pivot seat 320, a mounting pad 330, a mushroom head 350, and a ball bearing 340. The bottom pivot seat 320 is fixedly connected to the gate head. The mushroom head 350 is snapped onto the bottom pivot seat 320 through the mounting pad 330. The ball bearing nest 310 is fixedly provided inside. The ball bearing 340 is provided with a spherical cavity that matches the ball head part of the mushroom head 350. The bearing nest 310 is fitted onto the ball head of the mushroom head 350 through the spherical cavity on the ball bearing 340, and the upper surface of the bearing nest is fixedly connected to the gate leaf, thereby achieving support for the lower part of the gate leaf 200 and enabling the rotation of the gate leaf.

[0048] Since the miter gate needs to block the water flow on both sides when it is closed, it is necessary to ensure a sufficient seal between the miter gate and the gate head, as well as between the two gate leaves, to prevent water leakage from the miter gate due to the water pressure difference on both sides.

[0049] Currently, there are corresponding sealing structures to stop water in the gaps between the gate leaf near the rotation axis 500 (i.e., the gate pivot assembly 220 on the gate leaf) and the lock head seat assembly 120, the gap between the bottom of the gate leaf and the bottom surface of the lock head, and the gap between the two gate leaves. However, the bearing housing 310 of the bottom pivot device 300 and the gate leaf 200 are installed together, so it is inevitable that water leakage or water jetting will occur between the bearing housing and the gate leaf. Water leakage or water jetting will cause corrosion of the bearing housing mating surface and fastening bolts, which will have a certain impact on the service life and safe operation of the lock.

[0050] To address the issue of water leakage or jetting between the bearing housing and the gate leaf, this embodiment provides a water-stopping system for a miter gate in a ship lock, the specific structure of which is as follows: Figures 1-12 As shown, the lock miter gate water-stopping system includes:

[0051] The door hinge sealing line is formed by the door hinge column assembly 220 of the door leaf 200 and the pillow seat assembly 120 on the gate head 100 when the miter door is closed.

[0052] Specifically, the door pivot assembly 220 is part of the door leaf, and it is a side component of the door leaf near the rotation axis 500. It should be noted that the axis of the door pivot assembly does not coincide with the rotation axis 500. For the specific structural form of the door leaf, please refer to the prior art. It will not be described in detail in this embodiment.

[0053] The bottom sealing line of the door leaf 200 and the bottom sill embedded part 110 embedded on the bottom surface of the gate head 100 form a bottom sealing line when the miter door is closed.

[0054] The door seal line is formed between the two door leaves 200 when the miter door is closed.

[0055] Bottom pivot sealing line: A sealing element is provided between the upper surface of the bottom pivot device 300 and the lower surface of the door leaf 200 near the end of the door pivot column assembly 220 to form a bottom pivot sealing line;

[0056] The door hinge sealing line, door bottom sealing line, and door interlocking sealing line are sequentially connected, and the two ends of the bottom pivot sealing line are respectively connected to the door hinge sealing line and the door bottom sealing line. The door hinge sealing line, door bottom sealing line, and door interlocking sealing line achieve water-stopping seals between the door leaf and the bolster assembly, between the door leaf and the bottom surface of the gate head, and between the two door leaves. The bottom pivot sealing line, with its two ends connected to the door hinge sealing line and the door bottom sealing line, achieves a seal between the bottom pivot device and the door leaf, effectively solving the problem of potential water leakage or jetting between the bearing housing and the door leaf, achieving zero water leakage after the miter gate is closed.

[0057] like Figures 3-5 As shown, the lower surface of the door leaf 200 is provided with a water-stop base frame 230, the bearing nest 310 in the bottom pivot device 300 is fixedly connected to the lower surface of the door leaf 200, and the bottom sealing strip 240 is disposed on the bearing nest 310 and the water-stop base frame 230; when the door leaf rotates, the bearing nest, the water-stop base frame and the bottom sealing strip rotate synchronously with the door leaf.

[0058] The bearing housing 310 includes a locking and fixing part 315 and a protrusion 313 that abuts against the water-stop base frame 230. The upper surface of the locking and fixing part 315 is provided with a sealing groove 311. One end of the sealing groove 311 extends to the lower end of the door pivot assembly 220, and the other end extends through the upper surface of the protrusion 313 to the lower edge of the end face of the protrusion 313 that abuts against the water-stop base frame 230. The sealing element is provided in the sealing groove 311.

[0059] Furthermore, the upper surface of the locking and fixing part 315, the upper surface of the protrusion 313, and the upper surface of the water-stop base frame 230 are flush to ensure that they can form a surface-to-surface engagement with the lower surface of the door leaf, thereby ensuring a sealing effect.

[0060] Furthermore, the bearing nest 310 also includes a mounting portion 312 located on the side of the protrusion 313 away from the water-stop base frame 230. The door bottom sealing strip 240 is disposed below the mounting portion 312, the protrusion 313 and the water-stop base frame 230. The lower surfaces of the mounting portion 312, the protrusion 313 and the water-stop base frame 230 are flush to ensure that they can form a surface-to-surface engagement with the upper surface of the door bottom sealing strip 240.

[0061] Specifically, the bearing housing 310 and the water-stop base frame 230 are both fixedly connected to the lower surface of the door leaf bottom plate 210 on the door leaf. The bearing housing is fastened to the door leaf bottom plate with bolts, and the water-stop base frame is welded to the door leaf bottom plate. Furthermore, the lower end of the door pivot assembly 220 is sealed with the locking fixing part by a seal; the locking fixing part 315 is sealed with the door leaf bottom plate 210 by a seal; the water-stop base frame is welded to the door leaf bottom plate 210 to achieve a sealed connection; the protrusion abuts against the end of the water-stop base frame and is sealed by a seal; and the door bottom sealing strip 240 forms a sealed connection with the mounting part 312, the protrusion 313, and the water-stop base frame 230. Therefore, sealing is achieved in the connection relationship of the door pivot assembly, bearing housing, water-stop base frame, door leaf bottom plate, and door bottom sealing strip, achieving a full sealing effect and preventing water from seeping out from the gaps between the parts. This configuration allows one end of the bottom pivot sealing line to be connected to the door hinge sealing line, and the other end to be connected to the bottom door sealing line, thus solving the problem of water leakage or spraying that may occur between the bearing housing and the door leaf, between the bearing housing and the door hinge column assembly, between the bearing housing and the water-stop base frame, and between the bearing housing and the bottom door sealing strip.

[0062] Preferably, the sealing element in this embodiment is an O-ring rubber strip. During installation, the O-ring rubber strip (SF6674) should be pressed into the sealing groove 311 first. The O-ring rubber strip should be measured to be more than 0.8mm above the upper surface of the bearing housing. Then, the bearing housing of the bottom pivot device and the bottom plate of the door leaf should be connected with high-strength bolts. After the connection is completed, a feeler gauge or light transmission should be used to check whether it is compacted.

[0063] For further details, please see Figure 5 , Figure 9 and Figure 10 The bearing nest 310 also includes a mounting groove 314. The door pivot assembly 220 includes a door pivot support pad 221 and a door pivot support pad seat. The lower end face of the door pivot support pad seat is located on the upper surface of the locking and fixing part 315, and the door pivot support pad seat is provided with a mounting cavity aligned with the mounting groove 314. The door pivot support pad 221 is disposed in the mounting cavity and its lower end is located in the mounting groove 314. Specifically, the sealing groove 311 extends to the bottom of the door pivot support pad seat.

[0064] See Figure 6The door bottom sealing strip 240 includes a first sealing section 241, a second sealing section 242, and a sealing block 243 arranged sequentially. The side of the sealing block 243 facing the bottom sill embedded part 110 forms the outer end point of the door bottom sealing line with the bottom sill embedded part 110, and the sealing blocks 243 on the two door leaves 200 form the lower end point of the door inter-door sealing line. Specifically, the outer end point of the door bottom sealing line refers to the end of the door bottom sealing line near the door inter-door sealing line, and its inner end point refers to the end of the door bottom sealing line near the door hinge sealing line. By using the sealing block as a transition between the door bottom sealing line and the door inter-door sealing line, the conversion and closed-loop connection between the door bottom sealing line and the door inter-door sealing line are realized, solving the problem of water leakage or water jetting at the connection point of the two sealing lines when the door bottom sealing line transitions to the door inter-door sealing line.

[0065] For further details, please see Figure 5 and Figure 7 The first sealing section 241 is provided with a sealing boss 2413. The sealing boss 2413 is placed in the mounting groove 314 and its upper surface abuts against the lower end face of the door shaft column support 221. The peripheral working surface of the sealing boss 2413 and the lower end of the pillow seat assembly 120 are sealed to form the lower end point of the door shaft sealing line.

[0066] See Figure 8 The bottom sill embedded part 110 includes a first bottom sill section 111 and a second bottom sill section 112 arranged in sequence, and the lower end face of the pillow seat assembly 120 is sealed to the upper surface of the first bottom sill section 111 away from the second bottom sill section 112.

[0067] Specifically, the peripheral working surface of the sealing boss 2413 and the door hinge support 221 together cooperate with the pillow seat assembly to form a door hinge sealing line. The sealing boss 2413 is part of the first sealing section 241, thereby realizing the transition between the door hinge sealing line and the door bottom sealing line on the movable door leaf. The bottom sill embedded part is part of the door bottom sealing line, and the pillow seat assembly is part of the door hinge sealing line. The lower end face of the pillow seat assembly is sealed to the first bottom sill section 111, thereby realizing the transition between the door hinge sealing line and the door bottom sealing line on the gate head. With this configuration, a closed-loop connection between the door hinge sealing line and the door bottom sealing line is realized, completely ensuring that there will be no leakage or water jetting at the junction of the door bottom sealing line and the door hinge sealing line.

[0068] Please continue reading Figure 7 and Figure 8 The center of the inner arc surface 2411 of the first sealing segment 241 is eccentrically positioned relative to the center of its outer arc surface 2412, and the radial width of the first end 2414 of the first sealing segment 241 is smaller than the radial width of its second end 2415 (the radial width refers to the width of the first sealing line in the radial direction). Figure 8 In this diagram, R1 represents the radius of the inner arc surface 2411, and R2 represents the radius of the outer arc surface 2412. The center of the inner arc surface 2411 is located on the rotation axis 500 of the door leaf 200, and the center and radius of the sealing surface of the first bottom sill section 111 are consistent with the center and radius of the outer arc surface 2412. This ensures that there is no interference between the first sealing section and the first bottom sill section during the rotation of the door leaf, and achieves a good sealing effect.

[0069] Furthermore, the peripheral working surface of the sealing boss 2413 that mates with the pillow seat assembly 120 is coplanar with the outer arc surface 2412. Coplanarity here means that the peripheral working surface of the sealing boss that mates with the pillow seat assembly is also an arc surface, and the center and radius of this arc surface are the same as those of the outer arc surface 2412. The outer arc surface is the end of the door bottom sealing line, and the sealing boss is the end of the door hinge sealing line. This arrangement ensures that the door hinge sealing line and the door inter-sealing line intersect, achieving a smooth transition between the two sealing lines.

[0070] See Figure 7 and Figure 12 In this embodiment, the door bottom sealing strip 240 includes a horizontal section 2416 and a vertical section 2417, wherein the horizontal section 2416 and the vertical section 2417 form an L-shaped structure. The sealing boss 2413 is located on the horizontal section. The horizontal section is used to engage with the bearing housing 310 and the water-stop base frame 230 to form a seal, and the vertical section is used to form a seal with the bottom sill embedded part as a door bottom sealing line; at the same time, as Figure 12 As shown, since the bottom door sealing strip in this embodiment has an L-shaped structure, the vertical section can fit tightly against the bottom sill embedded part under the action of water pressure to achieve a good seal, avoiding the problem of seal failure caused by wear and aging of the bottom door sealing strip during operation.

[0071] The structure of the door hinge sealing line and the door-to-door sealing line is existing technology. The composition of the door hinge sealing line and the door-to-door sealing line will be briefly described below in this embodiment. Figures 10-11 As shown.

[0072] Specifically, a sealing pad 250 is provided on the side of the door leaf 200 away from the door pivot assembly 220, and a steel water-stop seal is formed between the sealing pads 250 of the two door leaves 200 and between the door pivot assembly 220 and the pillow seat assembly 120.

[0073] The pillow seat assembly 120 includes a pillow seat 121 and a pillow 122. The pillow seat 121 is anchored in the concrete of the gate head, and the pillow 122 is disposed in the pillow seat 121. The pillow is adjusted in position by bolts and then epoxy mortar is poured. The door pivot support includes a door pivot baffle 222 and a door pivot end plate 223 (the door pivot end plate 223 is also the side end plate of the door leaf). The two door pivot baffles 222 are arranged in parallel. On the side of the door hinge end plate 223 facing the pillow assembly, the two door hinge baffles 222 and the door hinge end plate 223 form the mounting cavity. The door hinge support 221 is placed inside the mounting cavity, and the inside of the mounting cavity is filled with epoxy mortar. The door hinge support 221 rotates with the door leaf. When the miter door is closed, the door hinge support 221 and the pillow pad 122 are tightly fitted to form a steel water-stop seal, thereby achieving the effect of sealing and stopping water.

[0074] Similarly, after the position of the sealing support 250 is determined, epoxy mortar is poured, and a steel water-stop seal is formed between the two sealing supports when the miter door is closed.

[0075] For details regarding the working principle and construction method of steel waterstop seals, please refer to existing technologies, such as Chinese patents with application numbers CN202220830964.9, CN202210722425.8, and CN201910645899.5, which disclose detailed information about steel waterstop seals. Therefore, this embodiment will not provide specific explanations of the structural form and working principle of the door hinge sealing line and the door inter-door sealing line.

[0076] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
