Description

Technical Field

[0001] This invention relates to the field of sealing equipment technology, and in particular to a hole sealing device. Background Technology

[0002] During shipbuilding, pre-drilled holes are unavoidable in ship plates (such as decks and bulkheads). These holes may have been CNC-machined in the early stages or incorrectly drilled on-site later. If these pre-drilled holes are not sealed, rainwater or construction water can easily seep through them to the next deck or flow into dry compartments, affecting the normal operation of the ship's internal functions. Therefore, a hole-sealing device is needed to seal these pre-drilled holes in ship plates. Summary of the Invention

[0003] One objective of this invention is to provide a hole sealing device that solves the problem of leakage in the through holes of the plate to be sealed, which affects the normal operation of the ship, by inflating an airbag to seal the through hole.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hole-sealing device is applied to a plate to be sealed, the plate having a through hole. The hole-sealing device includes a working airbag, an inflatable airbag, an inflation valve, and a sealing element. The working airbag includes a body, an inlet pipe, and an outlet pipe. Both the inlet pipe and the outlet pipe are connected to the inner cavity of the body. The inflatable airbag is connected to the inlet pipe for inflating and deflating the body. The inflation valve is located on the inlet pipe and is a one-way valve. The sealing element is located on the outlet pipe. The working airbag is inflated by the inflatable airbag, causing it to expand until a portion of its surface can fit against the inner wall of the through hole, thus sealing the through hole.

[0006] Optionally, it also includes a barometer having a data acquisition end disposed within the capsule.

[0007] Optionally, the bladder includes a first bladder portion and a second bladder portion that are connected to each other, wherein the outer peripheral wall between the first bladder portion and the second bladder portion is recessed inward to form a sealing portion, and the sealing portion is at least partially located within the through hole.

[0008] Optionally, a portion of the outer peripheral wall of the sealing portion protrudes outward to form a hole-fitting portion, which can fit against the hole wall of the through hole under the inflation action of the inflatable airbag.

[0009] Optionally, the sealing portion is arc-shaped so that at least a portion of the sealing portion can extend beyond the through hole and fit against the side wall of the plate to be sealed.

[0010] Optionally, the outer peripheral wall of the sealing portion outside the through hole is provided with an oleophilic coating, which can form a seal between the sealing portion and the side wall of the plate to be sealed under the action of oil molecules.

[0011] Optionally, the working airbag is provided with a first crease along the axis of symmetry, and both the first airbag portion and the second airbag portion are divided into two halves by the first crease.

[0012] Optionally, the working airbag is provided with a second crease, and there are at least two second creases located on both sides of the first crease, and the distance from each second crease to the first crease is greater than the distance from the sealing hole to the first crease.

[0013] Optionally, the inflatable airbag has an inlet chamber, an outlet chamber, a first inflation chamber, and a second inflation chamber inside; the inlet chamber is in communication with the external environment of the inflatable airbag; the outlet chamber is in communication with the inlet pipe; the first inflation chamber and the second inflation chamber are separated by a partition, and the capacity of the first inflation chamber is greater than the capacity of the second inflation chamber; one end of the first inflation chamber is in communication with the inlet chamber, and the other end is in communication with the outlet chamber; one end of the second inflation chamber is in communication with the inlet chamber, and the other end is in communication with the outlet chamber.

[0014] Optionally, a first pressing airbag and a second pressing airbag are respectively provided on both sides of the inflatable airbag; the first pressing airbag is connected to the first inflation chamber; and the second pressing airbag is connected to the second inflation chamber.

[0015] The beneficial effects of the present invention are as follows: During the process of sealing the through hole of the plate to be sealed, the working airbag is inserted into the through hole of the plate to be sealed (such as the pre-opening hole of the ship plate). The air is unidirectionally pressed into the working airbag through the inflation valve by the inflation airbag to inflate the working airbag. When the working airbag expands to the point that part of its surface can fit against the inner wall of the through hole, the sealing of the through hole is completed.

[0016] This method not only enables rapid sealing of through holes, preventing rainwater or construction water from leaking through the through holes in the plate to be sealed to the next deck or flowing into the dry compartment, thus ensuring dryness and normal operation of the ship's internal functions, but also facilitates the re-opening of through holes. Operators only need to open the sealing part located on the air outlet pipe to allow air to be discharged from the working airbag. The re-opening process does not require much operation of the device, and the disassembly process is simple and convenient, improving the overall work efficiency. Attached Figure Description

Detailed Implementation

[0024] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] During shipbuilding, pre-drilled holes are inevitable in both decks and bulkheads. These pre-drilled holes may be CNC-controlled in the early stages or incorrectly drilled on-site later. If these pre-drilled holes are not sealed, rainwater or water generated during construction can easily seep through these pre-drilled holes to the next deck or flow into the dry compartment, thus affecting the normal operation of the ship's internal functions.

[0028] Currently, steel plates are typically used to temporarily cover pre-drilled holes, or enclose them with partitions. However, when using temporary covers, spot welding is generally used for fixation to facilitate later removal. Temporary covers can prevent rainwater from falling directly into the holes during rainy days, but if there is water accumulation, it will flow into the gaps in the plates that are not fully welded. If partitions are used to seal the holes, although they can prevent water from flowing in, they must be fixed by continuous welding, which will require more work during later removal, thus increasing construction costs and efficiency.

[0029] Based on the above, please refer to Figures 1-5 This invention provides a hole sealing device that acts on a plate 100 to be sealed. The plate 100 has a through hole 110. The hole sealing device includes a working airbag 200, an inflatable airbag 300, an inflation valve 410, and a sealing element. The working airbag 200 includes a body 210, an inlet pipe 220, and an outlet pipe 230. Both the inlet pipe 220 and the outlet pipe 230 are connected to the inner cavity of the body 210. The inflatable airbag 300 is connected to the inlet pipe 220 and is used to inflate and deflate the body 210. The inflation valve 410 is located in the inlet pipe 220 and is a one-way valve. The sealing element is located in the outlet pipe 230. The working airbag 200 is inflated by the inflatable airbag 300, causing the working airbag 200 to expand until part of its surface can fit against the inner wall of the through hole 110, thereby sealing the through hole 110.

[0030] It should be noted that the plate to be sealed 100 can be a ship's plate, such as a deck or bulkhead. The through hole 110 can be a pre-drilled hole in the ship's plate. Both the working airbag 200 and the inflatable airbag 300 are made of elastic materials such as rubber. The sealing element is an exhaust valve 420 or a plug. The airbag 210 can be vented by opening the exhaust valve 420 or the plug. The inflation valve 410 is a one-way valve, and the gas flow direction of the inflation valve 410 is from the inflatable airbag 300 to the working airbag 200. By using the inflation valve 410 as the control valve on the air inlet pipe 220 of the working airbag 200, it is possible to prevent some of the gas in the working airbag 200 from flowing back to the inflatable airbag 300 during the inflation process, which would reduce the inflation efficiency of the working airbag 200. To prevent issues such as low pressure, an air inlet valve 430 can be installed at the air inlet of the inflatable airbag 300. The air inlet valve 430 is a one-way valve, and the gas flow direction of the inflation valve 410 is from the outside to the inflatable airbag 300. By setting the air inlet valve 430, it can be prevented that some gas is discharged from the inflatable airbag 300 to the outside when the inflatable airbag 300 is pressed, which would affect the inflation of the working airbag 200 by the inflatable airbag 300. Alternatively, a filter screen can be installed at the air inlet of the inflatable airbag 300. The filter screen can prevent external dust from entering the inflatable airbag 300 or the working airbag 200, and prevent excessive dust accumulation in the working airbag 200 from causing the working airbag 200 to increase in volume, which would affect the sealing of the sealing plate 100 by the working airbag 200.

[0031] In the process of sealing the through hole 110 of the plate to be sealed 100, the present invention uses a working airbag 200 inserted into the through hole 110 (such as a pre-drilled hole in a ship plate). Air is unidirectionally forced into the working airbag 200 through the inflation valve 410 via the inflation airbag 300, causing the working airbag 200 to inflate. Once the working airbag 200 inflates to the point where a portion of its surface can fit against the inner wall of the through hole 110, the through hole 110 is sealed. This method not only achieves sealing of the through hole 110... The rapid sealing of the airbag helps prevent rainwater or construction water from leaking through the through-hole 110 of the plate to be sealed 100 to the next deck or into the dry compartment, ensuring the dryness of the compartment and the normal operation of the ship's internal functions. It also facilitates the re-opening of the through-hole 110. Workers only need to open the vent valve 420 located on the vent pipe 230 to allow air to escape from the working airbag 200. The re-opening process requires minimal manipulation of the device, making disassembly simple and convenient, thus improving overall work efficiency. Furthermore, when removal is required later, simply opening the vent valve 420 to deflate the working airbag 200 allows it to be removed from the through-hole 110 of the plate to be sealed 100. Removal is very convenient, reducing construction costs and improving efficiency. Compared to the traditional method of using temporary covering plates, this invention provides a better sealing effect. Compared to the traditional method of sealing with a cofferdam, this invention does not require disassembling the weld points, saving the need for grinding the weld points after disassembly.

[0032] Please see Figure 1 The hole sealing device also includes a barometer 500, which has a data acquisition end located inside the bladder body 210. The barometer 500 measures the internal air pressure of the working airbag 200 bladder body 210, allowing for the determination of the working airbag's inflation level. This prevents the working airbag from being too low to properly seal the through hole 110 of the sealing plate 100. Furthermore, by appropriately releasing air from the working airbag 200 using the vent valve 420, the risk of explosion due to excessively high internal air pressure can be avoided.

[0033] Please see Figure 2The airbag 210 includes a first airbag portion 211 and a second airbag portion 212 that are connected to each other. The outer peripheral wall between the first airbag portion 211 and the second airbag portion 212 is recessed inward (that is, recessed towards the inner cavity of the working airbag 200) to form a sealing portion 213. The sealing portion 213 is at least partially located within the through hole 110. The sealing portion 213 increases the contact area between the working airbag 200 and the plate to be sealed 100, allowing the working airbag 200 to have sufficient area to fit against the plate to be sealed 100, which helps to enhance the sealing performance between the working airbag 200 and the plate to be sealed 100. Moreover, the sealing portion 213 can play a positioning role, so that the operator can accurately insert the working airbag 200 into the required position within the through hole 110 of the plate to be sealed 100.

[0034] It should be noted that you should refer to [link / reference]. Figure 2 The length of the first bladder portion 211 or the second bladder portion 212 along the length direction of the plate to be sealed 100 (that is, the left-right direction in the figure) is greater than the thickness of the first bladder portion 211 or the second bladder portion 212 along the thickness direction of the plate to be sealed 100 (that is, the up-down direction in the figure). This arrangement ensures that the sealing hole portion 213 located between the first bladder portion 211 and the second bladder portion 212 has sufficient area to contact the plate to be sealed 100.

[0035] Based on the sealing portion 213, the inventors also discovered that although the sealing portion 213 can increase the contact area between the working airbag 200 and the plate to be sealed 100, after the working airbag 200 inflates, please refer to... Figure 2 The portion of the sealing part 213 inside the through hole 110 does not easily contact the inner wall of the through hole 110, especially when the thickness of the plate to be sealed 100 is large. The area where the sealing part 213 fits against the inner wall of the through hole 110 becomes increasingly smaller, directly affecting the sealing performance between the sealing part 213 and the plate to be sealed 100. Please refer to... Figure 3 The present invention forms a sealing portion 214 by protruding outward from the outer peripheral wall of the sealing portion 213 (that is, protruding away from the inner cavity of the working airbag 200). The sealing portion 214 can fit against the wall of the through hole 110 under the inflation action of the inflatable airbag 300. Provided that the sealing portion 213 has sufficient area to contact the plate to be sealed 100, the sealing portion 214 can contact and fit against the inside of the through hole 110 after inflation, thereby sealing the through hole 110 from the inner wall of the through hole 110. This compensates for the sealing effect of the sealing portion 213 inside the through hole 110, further improving the sealing effect of the working airbag 200 through the sealing portion 213 on the through hole 110 of the plate to be sealed. This helps to prevent rainwater or construction water from entering the cabin, reduces the workload of cleaning accumulated water, ensures the cabin is dry, and prevents the ship plates from rusting due to long-term contact with moisture, thus improving the quality and efficiency of ship processing.

[0036] It should be noted that the first bladder portion 211, the second bladder portion 212, the sealing portion 213, and the patch portion 214 can be integrally molded from the same elastic material, or they can be composites of different elastic materials. Moreover, the elasticity of the elastic material that makes up the patch portion 214 and the sealing portion 213 is greater than that of the elastic material that makes up the first bladder portion 211 and the second bladder portion 212. This arrangement ensures that the patch portion 214 and the sealing portion 213 can preferentially expand outward when inflated, which helps to ensure that the patch portion 214 and the sealing portion 213 can fully contact the plate to be sealed 100, thereby ensuring that the working airbag 200 has a good sealing effect on the plate to be sealed 100.

[0037] Please see Figures 2-3 The sealing portion 213 is arc-shaped so that at least part of the sealing portion 213 can extend beyond the through hole 110 and fit against the side wall of the plate to be sealed 100. By setting the sealing portion 213 in an arc shape, it is possible to facilitate the outer wall of the sealing portion 213 to fit against the side wall of the plate to be sealed 100. On the other hand, it can also improve the puncture resistance of the sealing portion 213, which helps to avoid the edge of the through hole 110 of the plate to be sealed 100 from cutting the sealing portion 213.

[0038] It should be noted that a reinforcing layer can also be provided on the outer wall of the sealing part 213. The reinforcing layer can further improve the wear resistance and tear resistance of the sealing part 213, and can prevent the sealing part 213 from being scratched or abraded by the plate to be sealed 100 when it comes into contact with the plate to be sealed.

[0039] Please see Figure 4The sealing part 213 is provided with an oleophilic coating 215 on its outer peripheral wall outside the through hole 110. The oleophilic coating 215 can form a seal between the sealing part 213 and the side wall of the plate to be sealed 100 under the action of oil molecules. When sealing the through hole 110 of the plate to be sealed 100, first open the vent valve 420 to deflate the working airbag 200. Then, place the first bladder part 211 or the second bladder part 212 through the through hole 110 on the inner side of the plate to be sealed 100 (the side of the plate to be sealed 100 closest to the center of the ship is the inner side). Then, close the vent valve 420, open the inflation valve 410 and the air inlet valve 430, and inflate the airbag 300 by pressing it. This causes the airbag 300 to continuously draw air out and deliver it into the working airbag 200, causing the working airbag 200 to expand continuously. When the internal air pressure of the working airbag 200 reaches a certain level, the hole-attaching part 214 can then contact the through hole. The inner wall of the 110 contacts and adheres to the surface, and part of the outer peripheral wall of the sealing part 213 can contact and adhere to the side wall of the plate to be sealed 100. Then, the inflation of the working airbag 200 by the inflation airbag 300 is stopped. Then, oil is sprayed between the outer peripheral wall of the sealing part 213 and the side wall of the plate to be sealed 100. With the help of the oleophilic coating 215, it is easy to achieve oil sealing between the outer peripheral wall of the sealing part 213 and the side wall of the plate to be sealed 100. Moreover, since oil and water are immiscible, the oil can better prevent rainwater or construction water from entering the cabin through the pre-opening hole of the ship plate, thereby further improving the sealing effect of the working airbag 200 on the through hole 110 of the plate to be sealed 100, which helps to reduce the work of cleaning up water accumulation and ensures that the cabin is dry.

[0040] It should be noted that an oleophilic coating 215 can also be provided on the side wall of the plate to be sealed 100. This arrangement is more conducive to the rapid formation of a seal between the outer peripheral wall of the sealing part 213 and the side wall of the plate to be sealed 100. Furthermore, the inner and outer side walls of the plate to be sealed 100 are also provided with an oleophilic coating 215. The corresponding positions of the sealing part 213 and the inner or outer side wall of the plate to be sealed 100 are also provided with an oleophilic coating 215. This arrangement can form a seal from both the inner and outer sides of the plate to be sealed 100. Combined with the seal formed by the hole-attaching part 214 on the inner wall of the through hole 110, the working airbag 200 can seal the through hole 110 of the plate to be sealed 100 from three places: the outer side of the plate to be sealed 100, the inner wall of the through hole 110, and the inner side of the plate to be sealed 100. This gives the working airbag 200 a good sealing effect on the plate to be sealed 100, which helps to prevent rainwater or construction water from entering the cabin through the through hole 110 of the plate to be sealed 100.

[0041] Furthermore, the inventors discovered that, since the through-hole 110 of the plate to be sealed 100 is often relatively small in diameter, if the working airbag 200 in its deflated state is rolled up arbitrarily, the first airbag portion 211 or the second airbag portion 212 is prone to interference with the inner wall of the through-hole 110 when passing through it, which is not conducive to placing the first airbag portion 211 or the second airbag portion 212 inside the plate to be sealed 100 through the through-hole 110. Please continue reading. Figure 4 In this invention, a first crease 610 is provided along the axis of symmetry in the working airbag 200, dividing both the first airbag portion 211 and the second airbag portion 212 into two halves. The first crease 610 provides an auxiliary line for correctly folding the working airbag 200, assisting the operator in folding and rolling up the entire working airbag 200 in its deflated state, and allowing the first airbag portion 211 or the second airbag portion 212 to pass more easily through the through hole 110.

[0042] Based on the first crease 610, please continue reading. Figure 4 The working airbag 200 is provided with a second crease 620. There are at least two second creases 620, located on both sides of the first crease 610, and the distance from each second crease 620 to the first crease 610 is greater than the distance from the sealing hole 213 to the first crease 610. The second creases 620 provide an auxiliary line for correctly folding the working airbag 200. Combined with the first crease 610, the first airbag portion 211 or the second airbag portion 212 can be folded into a smaller shape. This not only helps the first airbag portion 211 or the second airbag portion 212 to be placed inside the sealing plate 100 through the through hole 110, but also makes it easier for the folded working airbag 200 to unfold without becoming messy. In other words, the first airbag portion 211 or the second airbag portion 212 placed inside the sealing plate 100 through the through hole 110 can easily unfold into the required shape.

[0043] It should be noted that the number of second creases 620 on the first pouch 211 or the second pouch 212 is not limited to two, but can also be three, four, five, etc. The specific number can be designed according to actual needs.

[0044] In one embodiment, please refer to Figure 5 The inflatable airbag 300 has an inlet chamber 330, an outlet chamber 340, a first inflation chamber 310, and a second inflation chamber 320 inside. The inlet chamber 330 is connected to the external environment of the inflatable airbag 300, and the outlet chamber 340 is connected to the inlet pipe 220. The first inflation chamber 310 and the second inflation chamber 320 are separated by a partition 350. The capacity of the first inflation chamber 310 is greater than that of the second inflation chamber 320. One end of the first inflation chamber 310 is connected to the inlet chamber 330, and the other end is connected to the outlet chamber 340. One end of the second inflation chamber 320 is connected to the inlet chamber 330, and the other end is connected to the outlet chamber 340.

[0045] By dividing the inner cavity of the inflatable airbag 300 into an air inlet chamber 330, an air outlet chamber 340, a first inflation chamber 310, and a second inflation chamber 320, the air inlet chamber 330 serves as the chamber for the inflatable airbag 300 to take in air from the external environment, while the air outlet chamber 340 serves as the chamber for the inflatable airbag 300 to inflate the working airbag 200. The first inflation chamber 310 and the second inflation chamber 320 can each serve as a chamber for the inflatable airbag 300 to be pressed and deflated, or they can both serve as chambers for the inflatable airbag 300 to be pressed and deflated. When the inflatable airbag 300 inflates the deflated working airbag 200, the sidewalls of the inflatable airbag 300 containing the first inflation chamber 310 and the second inflation chamber 320 can be pressed simultaneously. The pressure is adjusted so that the first inflation chamber 310 and the second inflation chamber 320 can simultaneously draw air out and inflate the working airbag 200, allowing the inflatable airbag 300 to inflate the working airbag 200 with maximum efficiency. When the pressure gauge 500 detects that the air pressure value of the working airbag 200 is close to the preset value, it can be selected to press only the side wall of the inflatable airbag 300 where the first inflation chamber 310 or the second inflation chamber 320 is located to continue inflating the working airbag 200. This can continue to inflate the working airbag 200 so that the air pressure of the working airbag 200 can reach the preset value, while avoiding the risk of the working airbag 200 being over-inflated and exploding due to overpressure.

[0046] It should be noted that the partition 350 is made of a soft, elastic material such as silicone, so that it does not affect the operator's ability to simultaneously inflate the airbag 300 containing both the first inflation chamber 310 and the second inflation chamber 320. The capacity of the first inflation chamber 310 can be 1.5 to 2 times that of the second inflation chamber 320, which makes it easier for the operator to select the appropriate efficiency for inflating the working airbag 200.

[0047] Based on the design of the first inflation chamber 310 and the second inflation chamber 320, the inventors discovered that when the side wall of the inflatable airbag 300 containing the first inflation chamber 310 (or the second inflation chamber 320) is pressed, the partition 350 also experiences partial force and deformation. This causes the side wall of the inflatable airbag 300 containing the second inflation chamber 320 (or the first inflation chamber 310) to also be affected and deform accordingly. In other words, the first inflation chamber 310 and part of the second inflation chamber 320 (or the second inflation chamber 320 and part of the first inflation chamber 310) participate in inflating the working airbag 200. This prevents the operator from effectively inflating the working airbag 200 by simply pressing the side wall of the inflatable airbag 300 containing the first inflation chamber 310 or the second inflation chamber 320. Please continue reading. Figure 5This invention provides a first pressing airbag 311 and a second pressing airbag 321 on both sides of the inflatable airbag 300. The first pressing airbag 311 is connected to the first inflation chamber 310, and the second pressing airbag 321 is connected to the second inflation chamber 320. By connecting the first pressing airbag 311 to the outside of the first inflation chamber 310 and the second pressing airbag 321 to the outside of the second inflation chamber 320, there is no need to press the side wall of the inflatable airbag 300 containing the first inflation chamber 310 or the second inflation chamber 320. This avoids the situation where the first inflation chamber 310 and the second inflation chamber 320 interfere with each other and inflate independently during pressing, ensuring that both the first inflation chamber 310 and the second inflation chamber 320 can independently inflate the working airbag 200, allowing the operator to select the required inflation efficiency according to the actual situation.

[0048] It should be noted that the inflatable airbag 300 may have pressing parts on the side wall of the first inflation chamber 310 away from the second inflation chamber 320 and on the side wall of the second inflation chamber 320 away from the first inflation chamber 310. By pressing the two pressing parts at the same time, the air in the first inflation chamber 310 and the second inflation chamber 320 can be squeezed at the same time, so as to force the air in the inflatable airbag 300 into the working airbag 200 to achieve the inflation effect.
