Description

Technical Field

[0001] This utility model relates to the field of emergency leak-sealing equipment technology, and more specifically to a bulkhead leak-sealing device. Background Technology

[0002] During use, the walls of ship bulkheads, equipment enclosures, and other enclosed spaces may develop holes or damage due to external impacts, structural fatigue, corrosion, or accidents. In the event of a leak, the internal medium will spill out through the damaged area, affecting not only the normal operation of the equipment but also potentially posing safety hazards in certain environments. Therefore, it is necessary to seal the damaged area as quickly as possible.

[0003] For emergency sealing of bulkhead breaches, existing technologies typically employ methods such as sealing boxes, sealing plates, or simple mechanical clamping devices. These devices generally work by attaching the box or plate to the outside of the bulkhead, then using screws, crossbars, or other structures to create a supporting relationship with the inside of the bulkhead, thereby clamping and sealing the damaged area. However, existing sealing devices are mostly modular structures, requiring on-site assembly of multiple components before use, involving numerous steps and hindering rapid installation in emergency situations.

[0004] Furthermore, some existing leak-sealing devices still require continuous manual pressure to be applied to the container during installation to counteract the reaction force from the medium pressure. The stability of the device depends on the continuous force applied by the operator, and the sealing effect can be affected by operator fatigue or external disturbances. At the same time, most existing devices use a single crossbar or single-point support structure, resulting in a relatively concentrated stress point on the inner side of the bulkhead, which leads to insufficient stability under high pressure.

[0005] In addition, existing leak-sealing devices often only install simple seals at the contact points between the housing and the bulkhead, while neglecting the sealing of the screw penetration points. This can easily create new leakage channels in these areas, affecting the overall sealing effect.

[0006] Therefore, existing technologies still have shortcomings in terms of emergency installation efficiency, structural stability, stress rationality, and overall sealing reliability, and need further improvement. Utility Model Content

[0007] This utility model provides a bulkhead leak sealer, which, through the combination of a box structure, a tie rod structure, a double crossbar structure and a sealing component, enables the device to form a stable force relationship in the installed state, so as to seal the damaged location of the bulkhead.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The bulkhead leak sealer includes a housing, a pull rod, and a handwheel for applying axial force to the pull rod. One end of the housing forms an open structure. A sealing frame is provided around the opening of the housing, and a sealing groove is provided on the inner side of the housing along the periphery of the opening.

[0010] The pull rod is arranged along the axial direction of the box body. One end of the pull rod passes through and is connected to the box body, and the other end extends out of the box body and is fixedly connected to the handwheel.

[0011] The pull rod is provided with a double crossbar structure at the end located on the front side of the box. The double crossbar structure includes a first crossbar and a second crossbar spaced apart along the axial direction of the pull rod.

[0012] A sealing connection structure is provided between the pull rod and the box body. The sealing connection structure is sleeved on the outside of the pull rod and located between the pull rod and the box body.

[0013] Preferably, the box body is a box-shaped structure with an opening on one side, and a handle is provided on the side wall of the box body.

[0014] Preferably, the pull rod includes a smooth section and a threaded section, with the threaded section located at the end near the handwheel.

[0015] Preferably, both the first and second crossbars are arranged laterally and connected to the tie rod via connectors, with the first and second crossbars arranged parallel to each other.

[0016] Preferably, the first crossbar and the second crossbar are spaced apart along the axial direction of the pull rod and are located in the front area outside the opening of the box.

[0017] Preferably, the sealing connection structure includes a connecting body, the connecting body having a through hole in the middle, and the pull rod passing through the through hole.

[0018] Preferably, a sealing ring is provided on one side of the connecting body, and the sealing ring is located between the connecting body and the housing.

[0019] Preferably, a limiting structure is provided on the other side of the connecting body, and the limiting structure is configured to cooperate with the sealing ring.

[0020] Preferably, the handwheel and the pull rod are coaxially arranged and fixedly connected.

[0021] Preferably, the sealing frame is configured to cooperate with the sealing groove and surrounds the periphery of the opening of the box.

[0022] Compared with the prior art, this utility model forms an integral assembly relationship between the box structure and the tie rod structure, so that the leak-sealing device does not need to be temporarily assembled in use, reducing operation steps and facilitating rapid installation in emergency situations such as bulkhead damage.

[0023] By setting up a double crossbar structure with axial spacing at the front end of the tie rod, the tie rod forms a multi-point support relationship on the inner side of the bulkhead. Compared with a single crossbar structure, the force on the inner side is more dispersed, the overall stress stability is higher, and it is beneficial to improve the structural reliability of the device under pressure.

[0024] By using a pull rod to penetrate the enclosure and a handwheel at the rear end, the enclosure, pull rod, and double crossbars form a tensioning path from the inside out after installation. This avoids relying solely on manual continuous pressure on the enclosure, allowing the device to maintain a stable fit under sealed conditions.

[0025] This invention features a sealing frame around the opening of the housing and a sealing groove inside the housing. This allows the sealing structure to be constrained by the housing structure during assembly, enabling a stable sealing fit under the axial action of the tie rod, which improves the reliability of sealing at damaged locations.

[0026] In addition, by setting a sealing connection structure between the tie rod and the housing, an independent sealing node is formed at the point where the tie rod passes through, reducing the possible leakage path at that point and improving the sealing integrity of the overall leak-proof structure.

[0027] In summary, this utility model, through the combination of a box body, a pull rod, double crossbars, and a sealing structure, has significant improvements in structural stability, rational force path, and sealing reliability, and is suitable for emergency leak sealing scenarios in locations such as bulkheads.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] like Figures 1 to 7 As shown, the bulkhead leak stopper described in this embodiment includes a housing 1, a handle 2, a sealing frame 3, a pull rod 4, a first crossbar 5, a second crossbar 6, a handwheel 8, and a sealing connection structure 9. All of the above components are arranged along the same axial direction to form an integral leak-stopping device structure.

[0041] The container 1 has a box-like structure with an opening on one side, which is positioned to face the location of the bulkhead damage. A handle 2 is fixedly installed on the side wall of the container 1, forming a secure connection with the side wall, facilitating the operator's grip and position adjustment of the container 1 during handling, alignment, and installation. A sealing frame 3 is integrally formed around the opening of the container 1, continuously distributed along the edge of the opening, creating a complete annular contact area when the container 1 is close to the bulkhead.

[0042] On the inner side of the housing 1, a sealing groove 101 is provided along the periphery of the opening. The sealing groove 101 and the sealing frame 3 correspond to each other in spatial position. The sealing groove 101 is used to accommodate the sealing structure, so that the sealing structure is restricted to the structural position of the housing 1 in the assembled state, and avoids displacement during the pressure process.

[0043] The pull rod 4 is arranged along the axial direction of the housing 1. One end of the pull rod 4 passes through the housing 1 and extends out of the rear side of the housing 1. The pull rod 4 and the housing 1 are sealed together by a sealing connection structure 9. A handwheel 8 is fixedly connected to the rear end of the pull rod 4. The handwheel 8 is coaxially arranged with the pull rod 4, allowing the operator to apply axial force to the pull rod 4 by rotating the handwheel 8. The pull rod 4 includes a smooth section and a threaded section 401. The threaded section 401 is located at the end near the handwheel 8, and the smooth section is located at the end near the housing 1.

[0044] A double crossbar structure is provided at the end of the pull rod 4 located on the front side of the housing 1. The double crossbar structure includes a first crossbar 5 and a second crossbar 6. The first crossbar 5 and the second crossbar 6 are arranged at intervals along the axial direction of the pull rod 4. Both are transversely arranged and are fixedly connected to the pull rod 4 by connectors, so that the first crossbar 5 and the second crossbar 6 maintain their relative positions when the pull rod 4 moves axially. The first crossbar 5 and the second crossbar 6 are arranged parallel to each other, forming a double support structure at the front end in space.

[0045] A sealing connection structure 9 is provided between the pull rod 4 and the housing 1, such as Figure 4 and Figure 5 As shown, the sealing connection structure 9 includes a connecting body 902, which is generally annular in shape. A through hole 903 is provided at its center, through which the pull rod 4 passes, allowing it to move axially relative to the connecting body 902. A sealing ring 901 is provided on one side of the connecting body 902, located between the connecting body 902 and the housing 1, forming a seal at the point where the pull rod passes through in the assembled state. A limiting structure 904 is provided on the other side of the connecting body 902, which cooperates with the sealing ring 901 to keep the sealing ring 901 stable in the axial direction.

[0046] In practical use, the operator first holds the box 1 with handle 2 and aligns the open end of the box 1 with the damaged hole in the bulkhead. Then, the pull rod 4 and its front first crossbar 5 and second crossbar 6 are pushed in together along the direction of the damaged hole, so that the double crossbar structure is completely inserted into the inner space of the bulkhead.

[0047] After the double crossbar structure enters the inner side of the bulkhead, the axial position of the tie rod 4 is adjusted so that the first crossbar 5 and the second crossbar 6 are located at different axial positions on the inner side of the bulkhead, thus forming support points distributed front and back on the inner side of the bulkhead. Then, the handwheel 8 is rotated to move the tie rod 4 axially towards the container 1, so that the first crossbar 5 and the second crossbar 6 gradually form a stable support relationship with the inner side of the bulkhead.

[0048] As the pull rod 4 continues to move axially, the container 1 gradually approaches the outer side of the bulkhead under the traction of the pull rod 4. The sealing frame 3 at the opening of the container 1 contacts the outer surface of the bulkhead, and the sealing structure in the sealing groove 101 deforms under pressure, thereby forming a continuous sealing and fitting area between the container 1 and the bulkhead. At the same time, the sealing ring 901 in the sealing connection structure 9 forms a seal at the position where the pull rod 4 passes through, preventing the formation of a leakage channel at that position.

[0049] After the above operations are completed, the bulkhead sealer forms an overall force-bearing system consisting of the first crossbar 5, the second crossbar 6, the tie rod 4, and the box 1. The box 1 is stably attached to the outside of the bulkhead, and the double crossbar structure is stably supported on the inside of the bulkhead, thereby completing the sealing of the damaged location of the bulkhead.

[0050] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
