Description

Technical Field

[0001] The invention relates to the technical field of dock door maintenance, and in particular to an adaptive sealing mechanism for repairing a dock door rock wall. Background Art

[0002] A floating dock is a special type of dock used primarily for repairing and building various vessels, particularly large ones, providing a floating work platform. When a floating dock is in use for ship repair or construction work, the dock doors are closed, sealing the dock entrance and isolating the dock chamber from the waters outside. However, the maintenance process can generate impurities that contaminate the waters, especially for vessels with damaged fuel tanks. This oil pollution can cause serious pollution.

[0003] To this end, Chinese patent CN213566387U discloses a floating dock isolation device, which introduces the hull into the floating dock through an opening, and then powers on the motor to start the rotation shaft in the forward direction, which in turn drives the threaded rod to rotate, and the threaded rod drives the threaded pipe to rotate, thereby causing the sealing plate to rise, and the opening to be sealed under the action of the sealing gasket. The control valve is opened, and the water in the floating dock is released from the drain pipe, thereby lowering the height of the ship and repairing the ship. During the repair process, oil pollution will not leak out, and the oil pollution is effectively isolated.

[0004] The dock gate is a watertight gate that seals the dock entrance, used to close the dock entrance and separate the dock chamber from the waters outside the dock. The ground and rock wall outside the dock entrance are easily damaged by the environment or ship collisions. When the dock gate rock wall is damaged, the isolation effect is affected. Therefore, the damaged area needs to be repaired in time. During the repair process, the debris and dirt around the dock gate rock wall need to be cleaned to ensure that the repair area is clean and tidy, and a dry construction space is constructed to smoothly carry out the dock entrance rock wall crack detection and repair work.

[0012] Preferably, the limiting assembly includes an oblique clamping block and a second elastic member, the oblique clamping block is slidably mounted on the lateral push rod, the two ends of the second elastic member are respectively connected to the oblique clamping block and the lateral push rod, a clamping slot that cooperates with the oblique clamping block is opened in the branch pipe, and when the oblique clamping block and the clamping slot are engaged, the lateral push rod is restricted from extending; when the movable block moves toward the direction close to the sealing block, the oblique clamping block is driven to move toward the direction away from the clamping slot.

[0013] Preferably, a control assembly and a transmission assembly are provided in the telescopic tube.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes the function of sealing a construction space at an isolated location on the dock rock wall through a surrounding wall and a control mechanism, and cooperates with a water pump to achieve the effect of keeping the construction space dry during the maintenance process, so as to facilitate operators to repair the damaged dock rock wall. The surrounding wall and the control mechanism solve the problem of how to quickly form a dry construction space on the dock rock wall. When the dock rock wall needs to be repaired, the number of isolation plates is adjusted according to the height of the dock rock wall, and multiple isolation plates are tightly connected by bolts to ensure the sealing of the surrounding wall. The surrounding wall is then moved to the damaged location of the dock rock wall, and the sealing rubber belt is then controlled by the control mechanism to extend until the sealing rubber belt is tightly matched with the ground outside the dock. Through the cooperation of the surrounding wall and the dock rock wall, a sealed construction space is formed at the dock rock wall. The water in the construction space is then pumped out by a water pump to form a dry construction space, which is convenient for operators to perform maintenance operations.

[0018] 2. The present invention realizes the function of connecting the linear drive and the sealing block through the telescopic tube and the first hinge seat. The sealing block is connected to the linear drive by a hinge, and the rotation axis direction of the hinge is perpendicular to the surface of the support frame. By controlling the up and down movement of the sealing block through the linear drive, each sealing block can rotate slightly around the hinge connected to the linear drive, and the distance between the two sealing blocks can be extended and shortened to a certain extent. In this way, the uniformity of the pressure distribution between the sealing block and the ground is improved, and the sealing rubber belt is pushed stably by the sealing block, so that the sealing rubber belt and the ground are stably matched, thereby improving the sealing effect of the sealing rubber belt.

[0019] 3. The present invention can realize the function of pushing the sealing rubber belt along the sealing block through the lateral pneumatic push rod. The lateral push rod pushes the sealing rubber belt from both sides of the first hinged seat, so that the sealing rubber belt can be in closer contact with the ground. Even if there is still a certain gap, the speed of water entering can be greatly reduced, thereby ensuring the normal progress of maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 and Figure 2 : An adaptive sealing mechanism for repairing dock rock walls, the adaptive sealing mechanism includes a surrounding wall 1 and a control mechanism 2, the surrounding wall 1 includes at least two isolation panels 11, multiple isolation panels 11 are equidistantly distributed in the vertical direction, and adjacent isolation panels 11 are tightly connected, a sealing rubber belt 12 is provided on the bottom isolation panel 11, and the control mechanism 2 is used to control the extension of the sealing rubber belt 12.

[0033] The sealing mechanism has reliable sealing performance, thereby ensuring a sufficiently dry construction environment inside the device. The contact surfaces that the sealing mechanism needs to seal mainly include the rock wall at the dock entrance, the dock threshold 51, and the ground outside the dock. Since the rock wall at the dock entrance is usually relatively flat, and the dock threshold 51 is inside the dry dock, the sealing contact surface can be easily cleaned and trimmed in advance. Therefore, effective sealing can be achieved by designing a U-shaped groove structure at the contact part of the sealing mechanism and using a sealing rubber strip. However, for the ground outside the dock, there are many stones that are difficult to clean, as well as unevenness problems such as slight depressions and small slopes on the ground that appear as the dock is used for a long time. These uneven ground phenomena will cause the dock maintenance device to be unable to fully fit with the ground, thereby affecting the sealing effect of the dock maintenance device. To this end, the present invention achieves the function of isolating and enclosing a construction space on the dock rock wall 4 through the enclosure 1 and control mechanism 2. Furthermore, in conjunction with a water pump, the construction space is kept dry during maintenance, making it easier for operators to repair damaged dock rock wall 4. The enclosure 1 and control mechanism 2 solve the problem of how to quickly create a dry construction space on the dock rock wall 4. Adjacent isolation panels 11 are connected by bolts, and the height of the enclosure 1 can be quickly adjusted by disassembling and assembling the bolts. When maintenance is required on the dock rock wall 4, the number of isolation panels 11 is adjusted according to the height of the dock rock wall 4, and multiple isolation panels 11 are tightly connected by bolts to ensure the sealing of the enclosure 1. Then the surrounding wall 1 is moved to the damaged part of the dock rock wall 4, and then the sealing rubber belt 12 is controlled to stretch through the control mechanism 2 until the sealing rubber belt 12 is tightly fitted with the ground outside the dock. Through the cooperation of the surrounding wall 1 and the dock rock wall 4, a closed construction space is formed at the dock rock wall 4, and then the water in the construction space is pumped out by a water pump to form a dry construction space, so that the operator can perform maintenance operations. The water pump is not shown in the figure.

[0034] Reference Figure 2-Figure 4 : The control mechanism 2 includes a bracket 21, a linear drive 22 and a sealing block 23. The bracket 21 is connected to the isolation plate 11 at the bottom end of the surrounding wall 1. There are at least three linear drives 22 and sealing blocks 23. Multiple linear drives 22 and sealing blocks 23 are equidistantly distributed along the outer edge of the bracket 21. The linear drive 22 is set on the bracket 21. The sealing block 23 is connected to the sealing rubber belt 12. Adjacent sealing blocks 23 are hinged to each other. The linear drive 22 is used to control the lifting and lowering of the sealing block 23.

[0035] Adjacent sealing blocks 23 are also connected end to end via hinges, like a chain. At the same time, because the diameter of the hinge shaft on the left side of the sealing block 23 is smaller than the diameter of the hinge hole on the right side of the sealing block 23, the hinge connection between two adjacent sealing blocks 23 is loose and can be misaligned. The distance between the two sealing blocks 23 can be extended or shortened to a certain extent. When the ground is uneven, such as when there is a slight slope, a slight local depression, or a large protrusion that is difficult to clean but affects the seal, these factors will prevent the sealing structure from achieving sufficient contact and fit with the ground in conventional sealing structures, resulting in insufficient sealing pressure in local areas, causing the sealing effect to deteriorate or even fail. The present invention, however, achieves the function of controlling the extension of the sealing rubber belt 12 through the bracket 21, linear actuator 22, and sealing block 23, so that the sealing rubber belt 12 tightly cooperates with the ground outside the dock door and the dock threshold 51, achieving the effect of forming a closed space to isolate the water body. The linear actuator 22 is preferably a linear pneumatic cylinder or a linear hydraulic cylinder. When repairing the dock rock wall 4, the number of isolation panels 11 is adjusted according to the height of the dock rock wall 4, and adjacent isolation panels 11 are tightly connected using bolts to ensure the sealing of the surrounding wall 1. The surrounding wall 1 is then moved to the damaged area of ​​the dock rock wall 4. The linear actuator 22 then drives the sealing block 23 up and down, pulling the sealing rubber belt 12 through the sealing block 23. The sealing rubber belt 12 then abuts against the uneven ground outside the dock. The linear actuator 22 then drives the sealing block 23 down, causing the sealing rubber belt 12 to stretch until it tightly fits the ground outside the dock. The interaction between the surrounding wall 1 and the dock rock wall 4 creates a sealed construction space at the dock rock wall 4. By controlling the driving force provided by the linear actuator 22, the pressure between each sealing block 23 and the ground is maintained constant, thereby ensuring the overall sealing effect of the sealing rubber belt 12.

[0036] Reference Figure 2-Figure 4 : A telescopic tube 221 is provided at the driving end of the linear drive 22, and a first hinge seat 231 is provided on the sealing block 23. The end of the telescopic tube 221 away from the linear drive 22 is hinged to the first hinge seat 231.

[0037] The present invention realizes the function of connecting the linear drive 22 and the sealing block 23 through the telescopic tube 221 and the first hinge seat 231. The sealing block 23 is connected to the linear drive 22 by a hinge, and the axis of rotation of the hinge is perpendicular to the surface of the support frame. By controlling the up and down movement of the sealing block 23 by the linear drive 22, each sealing block 23 can rotate slightly around the hinge connected to the linear drive 22, and the distance between the two sealing blocks 23 can be extended and shortened to a certain extent. In this way, the uniformity of the pressure distribution between the sealing block 23 and the ground is improved, and the sealing rubber belt 12 is stably pushed by the sealing block 23, so that the sealing rubber belt 12 is stably matched with the ground, thereby improving the sealing effect of the sealing rubber belt 12.

[0038] Reference Figure 2-Figure 4 : Branch pipes 24 are provided on both sides of the telescopic tube 221, and the branch pipes 24 are filled with inert high-pressure gas. Side push rods 241 for supporting the sealing rubber belt 12 are provided on the branch pipes 24. When the side push rods 241 are extended under the action of the gas pressure in the branch pipes 24, the sealing rubber belt 12 can be pushed.

[0039] The present invention uses a lateral pneumatic push rod to push the sealing rubber belt 12 along the sealing block 23. Since the sealing block 23 is elongated and rigid, a large gap between the sealing block 23 and the ground may exist when encountering a small protrusion, affecting the sealing performance of the sealing rubber belt 12. The branch pipe 24 is sealed and filled with high-pressure inert gas. To this end, a lateral pneumatic push rod is provided. Before maintenance, the linear actuator 22 first drives the sealing block 23 downward, pushing the sealing rubber belt 12 through the sealing block 23 to achieve a preliminary sealing effect. High-pressure gas is then introduced into the branch pipe 24 to push the lateral push rod 241. The lateral push rod 241 pushes the sealing rubber belt 12 from both sides of the first hinge seat 231, allowing the sealing rubber belt 12 to make closer contact with the ground. Even if a certain gap still exists, the speed of water ingress can be significantly reduced, ensuring the normal progress of maintenance work.

[0040] Reference Figure 4 and Figure 5 : The sealing block 23 is provided with a guide frame 232 for limiting the range of movement of the lateral push rod 241, and the sealing block 23 is provided with a through slot 233 for the lateral push rod 241 to extend. When the lateral push rod 241 extends, the sealing rubber belt 12 is pushed through the through slot 233 on the sealing block 23.

[0041] The present invention realizes the function of guiding the movement of the lateral push rod 241 through the cooperation of the guide frame 232 and the through groove 233, and the rotation angle of the sealing block 23 can be limited by the abutment effect between the guide frame 232 and the lateral push rod 241. After the lateral push rod 241 is extended, if the lateral push rod 241 is grounded with the guide frame 232 after extension, the thrust of the lateral push rod 241 can drive the sealing block 23 to rotate relative to the telescopic tube 221, so that the sealing block 23 tends to be horizontal, avoiding excessive rotation of the sealing block 23 due to the flatness of the ground, causing large leakage, and after the sealing block 23 is closer to the horizontal, the two lateral push rods 241 push the sealing rubber belt 12 so that the sealing rubber belt 12 is close to the ground. Since the stroke of the lateral push rod 241 is relatively short, it can only assist in pushing the sealing block 23. Once the sealing block 23 rotates to one side at a large angle, the lateral push rod 241 on the other side cannot contact the sealing rubber belt 12 even if it is extended to its longest position, and thus cannot achieve the desired pushing effect. For this reason, a guide frame 232 is provided, and the inclination state of the sealing block 23 is first adjusted by the cooperation between the lateral push rod 241 and the guide frame 232, and then the lateral push rod 241 is used to push it. If the sealing block 23 is tightly fitted with the ground, the lateral push rod 241 will be pressed against the ground after being extended, which can also achieve the effect of assisting the fit.

[0042] Reference Figure 4 、 Figure 6 and Figure 7 : The branch pipe 24 is provided with an auxiliary mechanism 3 for controlling the extension and retraction of the lateral push rod 241. The auxiliary mechanism 3 includes a movable block 31 and a limiting assembly 32. The movable block 31 is movably set on the sealing block 23. The movable block 31 is provided with a first elastic member 311. The two ends of the first elastic member 311 are respectively connected to the movable block 31 and the sealing block 23. The limiting assembly 32 is used to limit the extension of the lateral push rod 241. When the movable block 31 is squeezed and approaches the sealing block 23, the first elastic member 311 contracts, and the movable block 31 releases the movement restriction of the limiting assembly 32 on the lateral push rod 241. The lateral push rod 241 is extended under the push of the high-pressure gas in the branch pipe 24.

[0043] The present invention achieves the function of controlling the extension of the lateral push rod 241 through the movable block 31 and the limiting assembly 32. Since the lateral push rod 241 only plays an auxiliary role in supporting and pushing the sealing block 23, it is usually necessary to extend it after the sealing block 23 contacts the ground. At the same time, in order to improve installation efficiency and avoid the need to introduce high-pressure gas into the branch pipe 24 after the linear actuator 22 drives the sealing block 23 to extend, the movable block 31 and the limiting assembly 32 are provided. When the sealing block 23 is in contact with the ground, the movable block 31 is not subjected to pressure. Under the restriction of the limiting assembly 32, the lateral push rod 241 will not extend under the action of the high-pressure gas. Until the sealing block 23 contacts the ground, the movable block 31 is squeezed, the first elastic member 311 contracts, and the movable block 31 drives the limiting assembly 32, releasing the restriction on the movement of the lateral push rod 241 by the limiting assembly 32. The lateral push rod 241 extends under the action of the gas pressure, providing auxiliary support and pushing the sealing rubber block further into contact with the ground.

[0044] Reference Figure 6 、 Figure 8 and Figure 9 : The limiting assembly 32 includes an oblique clamping block 321 and a second elastic member 322. The oblique clamping block 321 is slidably mounted on the lateral push rod 241. The two ends of the second elastic member 322 are respectively connected to the oblique clamping block 321 and the lateral push rod 241. A clamping groove 323 that cooperates with the oblique clamping block 321 is opened in the branch pipe 24. When the oblique clamping block 321 and the clamping groove 323 are clamped, the lateral push rod 241 is restricted from extending; when the movable block 31 moves toward the direction close to the sealing block 23, the oblique clamping block 321 is driven to move toward the direction away from the clamping groove 323.

[0045] The present invention utilizes the oblique block 321, the second elastic member 322, and the slot 323 to restrict the extension of the lateral push rod 241. When the movable block 31 is not in contact with the ground, the oblique block 321 engages with the slot 323, thereby restricting the extension of the lateral push rod 241. However, when the movable block 31 is in contact with the ground and is squeezed by the ground, the first elastic member 311 contracts, and the movable block 31 approaches the sealing block 23. Simultaneously, the movement of the movable block 31 controls the separation of the oblique block 321 from the slot 323, allowing the lateral push rod 241 to extend under the action of air pressure, pushing the sealing rubber belt 12.

[0046] Reference Figure 6 and Figure 7: A control component 33 and a transmission component 34 are provided in the telescopic tube 221. The control component 33 is used to release the movement restriction of the limiting component 32 on the lateral push rod 241. The movable block 31 is connected to the control component 33 through the transmission component 34. In the working state, when the movable block 31 moves upward relative to the sealing block 23, the movable block 31 drives the control component 33 through the transmission component 34. The control component 33 overcomes the elastic force of the second elastic member 322 to control the oblique block 321 to move in the direction away from the card slot 323.

[0047] The present invention utilizes the control assembly 33 and the transmission assembly 34 to achieve the function of controlling the separation of the oblique clamping block 321 from the retaining slot 323 via the movable block 31. In the operating state, when the movable block 31 is pressed by the ground and approaches the sealing block 23, the movable block 31 drives the control assembly 33 via the transmission assembly 34. The control assembly 33 controls the separation of the oblique clamping block 321 from the retaining slot 323, thereby releasing the extension restriction of the lateral push rod 241 by the restriction assembly 32.

[0048] Reference Figure 6 、 Figure 8 and Figure 9 : The control component 33 includes an oblique push block 331 and a third elastic member 332. The oblique push block 331 is slidably installed in the branch pipe 24, and the oblique push block 331 is located in the card slot 323. The two ends of the third elastic member 332 are respectively connected to the oblique push block 331 and the branch pipe 24.

[0049] The present invention achieves the function of controlling the separation of the oblique clamping block 321 from the clamping slot 323 through the oblique push block 331 and the third elastic member 332. When the movable block 31 moves closer to the sealing block 23, the elastic force of the third elastic member 332 is overcome, driving the oblique push block 331 toward the oblique clamping block 321. The oblique push block 331 then presses the oblique clamping block 321, overcoming the elastic force of the second elastic member 322 to drive the oblique clamping block 321 away from the clamping slot 323, thereby separating the oblique clamping block 321 from the clamping slot 323 and releasing the extension restriction of the lateral push rod 241 by the restriction assembly 32.

[0050] Reference Figure 6 、 Figures 8-10 : The transmission assembly 34 includes a telescopic rod 341, a second hinge seat 342 and a fourth elastic member 343. The telescopic rod 341 is slidably installed in the telescopic tube 221. The second hinge seat 342 is set on the movable block 31. The telescopic rod 341 is hinged to the second hinge seat 342. The two ends of the fourth elastic member 343 are respectively connected to the telescopic rod 341 and the telescopic tube 221. The telescopic rod 341 is provided with an oblique protrusion 3411. When the movable block 31 moves toward the sealing block 23, the oblique protrusion 3411 on the telescopic rod 341 squeezes the oblique push block 331, overcomes the elastic force of the third elastic member 332, and drives the oblique push block 331 to move toward the direction close to the oblique clamping block 321.

[0051] The present invention achieves the function of driving the control assembly 33 through the movement of the movable block 31 through the telescopic rod 341, the second hinge seat 342, and the fourth elastic member 343. Both the oblique clamping block 321 and the oblique push block 331 are provided with inclined surfaces. When the oblique protrusion 3411 contacts the inclined surface of the oblique push block 331, the oblique push block 331 is driven to move through a squeezing action. When the oblique push block 331 moves in the direction of the oblique clamping block 321, the oblique push block 331 squeezes the inclined surface of the oblique clamping block 321, pushing the oblique clamping block 321 to move. When the movable block 31 moves toward the sealing block 23, the movable block 31 drives the telescopic rod 341 to move, and the oblique protrusion 3411 on the telescopic rod 341 squeezes the oblique pushing block 331, overcoming the elastic force of the third elastic member 332 and driving the oblique pushing block 331 to move toward the oblique clamping block 321. Then, the oblique pushing block 331 squeezes the oblique clamping block 321, overcoming the elastic force of the second elastic member 322 and driving the oblique clamping block 321 to move away from the clamping slot 323, so that the oblique clamping block 321 is separated from the clamping slot 323, thereby releasing the extension restriction of the limiting assembly 32 on the lateral push rod 241.
