[0038] According to one scheme of the present invention, a ship leak-proof device comprises: a pressure plate, one surface of which is provided with at least two bracket grooves, and the other surface is provided with a plurality of sealing grooves; a support rod, which is correspondingly movably supported in each bracket groove, and one end of the support rod is hinged in the bracket groove; a sealing structure, which is correspondingly arranged in each sealing groove and is used to abut and seal the damaged part on the ship; pressure is applied to the pressure plate by the support rod, and the pressure is transmitted to the sealing structure through the pressure plate, and the damaged part on the ship is abutted and squeezed by the sealing structure, so as to achieve sealing and plugging of the damaged part on the ship.

[0039] According to one solution of the present invention, two bracket grooves are provided on one surface of the pressure plate, and the two bracket grooves are arranged in parallel and aligned, and the two bracket grooves are arranged in opposite directions. With such an arrangement, when pressure is applied to the pressure plate through the support rod, because of the opposite arrangement of the two bracket grooves, when the pressure plate continues to transmit pressure downward, the pressure can be transmitted downward symmetrically and evenly, ensuring that the pressure plate and the sealing structure below it can evenly press the damaged part on the ship, effectively improving the plugging effect.

[0040] According to one solution of the present invention, the bracket groove includes: a first groove and a second groove connected to the first groove, the width of the first groove is greater than the width of the second groove; a hinge point is provided in the first groove, and a clip is provided in the second groove; one end of the support rod is hinged to the hinge point, and the other end of the support rod is clamped in the second groove by the clip. In this way, the hinge point connected with the support rod can be set through the first groove, and the overall multi-angle swing of the support rod can be achieved through the connection between the hinge point and the end of the support rod, so that when the support rod is separated from the clamping of the clip, the support rod can swing freely, so as to achieve support with the nearby support points and further apply pressure to the pressure plate. When use is completed, the support rod can be placed in the bracket groove, and the support rod can be clamped by the clip to achieve rapid storage of the support rod.

[0041] According to one solution of the present invention, after the other end of the support rod is separated from the bracket groove, the other end of the support rod can reciprocate in the direction of approaching and moving away from the pressure plate. With such a configuration, when a nearby support point is found, the support rod can be swung to approach the support point, and then the other end of the support rod can be telescopically moved to achieve abutment support between the support rod and the support point, and then the support rod can be telescopically moved and the support of the support point can be used to provide a reverse support force for the pressure plate, thereby applying pressure to the sealing structure, squeezing the damaged part on the ship through the sealing structure, and plugging the leak.

[0042] According to one solution of the present invention, the support rod comprises: an outer tube, a bayonet, an inner tube, a screw, a handle and a support foot; one end of the outer tube is hinged to a hinge point; the inner tube is arranged in the outer tube and can be telescopically moved at the other end of the outer tube; the bayonet is arranged on the outer wall of the other end of the outer tube and passes through the outer wall of the outer tube to be engaged with the outer wall of the inner tube; the screw is arranged in the inner tube and its outer wall is screwed with the inner wall of the inner tube; the handle is arranged on the outer wall of the end away from the inner tube when the screw is screwed out; the support foot is arranged at the end away from the inner tube when the screw is screwed out. With such a setting, the overall length of the support rod can be roughly adjusted by moving the inner tube, and the overall length of the support rod can be finely adjusted by rotating the handle to screw the screw into and out of the inner tube. With such a solution, the support rod can be quickly supported at a nearby support point, and the plugging pressure can be quickly applied by cooperating with the reverse support of the support point according to the plugging requirement, thereby realizing rapid plugging of the hull, and the pressure can be quickly adjusted according to the plugging requirement to ensure the plugging effect.

[0043] According to one solution of the present invention, two sealing grooves are provided on the other surface of the pressure plate, and the two sealing grooves are respectively arranged opposite to the two first grooves. In this way, the force-applying end of the support rod hinged in the first groove can face the sealing structure in the sealing groove, so that the force transmission effect of the support rod and the sealing structure can be effectively improved, and the sealing effect of the sealing structure on the damaged part of the ship can be effectively improved.

[0044] According to one solution of the present invention, the sealing structure is an elastic sealing structure, and when the pressure is transmitted through the support rod and the pressure plate, the sealing structure elastically squeezes the damaged part on the ship. With such a configuration, the effect of squeezing and sealing the damaged part on the ship by the sealing structure can be better, safer and more reliable, so that the sealing structure will not cause damage to the hull due to excessive pressure, and at the same time, it can effectively improve the ability to adapt to the structural shape of the damaged part of the hull, that is, improve the ability to adapt to deformation, ensure that it can be squeezed and sealed according to the structural shape of the damaged part, increase the applicable range of the damaged part, and improve the plugging efficiency.

[0045] According to one solution of the present invention, the sealing structure comprises: a mounting part, a first support plate, a return spring, a first limiting structure, a second support plate and a first sealing rubber; the mounting part is correspondingly mounted in a sealing groove (e.g., a circular groove); the first support plate is supported on the surface of the mounting part away from the sealing groove; the return spring is supported on the center of the surface of the first support plate away from the mounting part; the first limiting structure (e.g., a cylindrical structure) is supported on the four edges of the surface of the first support plate away from the mounting part; the second support plate is supported on the return spring, and its travel range through the return spring is limited by the first limiting structure; the first sealing rubber is supported on the surface of the second support plate away from the return spring, and when the return spring supports the second support plate so that the second support plate and the end of the first limiting structure cooperate and contact, the first sealing rubber protrudes from the end of the first limiting structure. In this way, the mounting part can stably and reliably mount the sealing structure in the sealing groove, and then the first limiting structure limits the elastic movement range of the second support plate and the first sealing rubber driven by the return spring, so as to ensure that the elastic movement of the second support plate and the first sealing rubber will not deviate from the predetermined range, and ensure that the elastic movement and the plugging achieved by the elastic movement are more accurate and reliable.

[0046] According to one solution of the present invention, the first limiting structure comprises: a first limiting plate (e.g., cylindrical), a baffle and a second sealing rubber; one end of the first limiting plate is respectively supported on the edges of the surface of the first support plate away from the mounting portion; the baffle is supported on the other end of the first limiting plate, and one side of the baffle protrudes toward the inner side of the first limiting plate, which is used to limit the second support plate; the second sealing rubber is supported on the surface of the baffle away from the first limiting plate. In this way, the first limiting plate can be supported on the surroundings of the reset spring and the second support plate, and the baffle is supported on one side of the second support plate.

At the same time, the first sealing rubber and the second sealing rubber can achieve coordinated plugging, and a sealing gap is formed between the two, effectively improving the plugging effect and plugging efficiency.

[0047] According to one solution of the present invention, the sealing structure further includes: a second limiting structure (such as a limiting cylinder), the second limiting structure is sleeved on the periphery of the reset spring, and one end of the second limiting structure is fixed on the first support plate; when the second support plate is limited by contacting the baffle of the first limiting structure, the height of the second limiting structure is lower than the height of the reset spring. With such a configuration, the reset spring can have space to drive the second support plate to perform elastic movement, so that the reset spring can not only be limited by the second limiting structure to avoid deformation due to force exceeding the bending deformation range, but also can ensure the elastic support of the second support plate, and ensure the effect of elastic sealing of the damaged parts on the ship.

[0060] One end of the support rod 2 is hinged to the hinge point 101, and the other end of the support rod 2 is clamped in the second groove 1022 through the clip 103. In this way, the hinge point that is connected with the support rod 2 can be set through the first groove 1021, and the support rod 2 can be swung at multiple angles through the connection between the hinge point 101 and the end of the support rod 2. When the support rod 2 is separated from the clamping of the clip 103, the support rod 2 can swing freely, so as to achieve support with the nearby support points and further apply pressure to the pressure plate 1. When the use is finished, the support rod 2 can be placed in the bracket groove 102, and the support rod 2 can be clamped by the clip 103 to achieve the rapid storage of the support rod 2.

[0061] Furthermore, in this embodiment, after the other end of the support rod 2 is separated from the bracket groove 102, the other end of the support rod 2 can reciprocate in the direction of approaching and moving away from the pressure plate 1. With such a configuration, when a nearby support point is found, the support rod 2 can be swung to approach the support point, and then the other end of the support rod 2 can be telescopically moved to achieve abutment support between the support rod 2 and the support point, and then the support of the support rod 2 and the support point can provide a reverse support force for the pressure plate 1, so as to apply pressure to the sealing structure, squeeze the damaged part on the ship through the sealing structure, and achieve leak plugging.

[0062] Furthermore, if Figure 2 As shown, in this embodiment, the support rod 2 includes: an outer tube 201, a bayonet 202, an inner tube 203, a screw rod 204, a handle 205 and a support foot 206;

[0063] One end of the outer tube 201 is hinged to the hinge point 101;

[0064] The inner tube 203 is disposed in the outer tube 201 and can be telescopically moved at the other end of the outer tube 201;

[0065] The bayonet pin 202 is disposed on the outer wall of the other end of the outer tube 201 and passes through the outer wall of the outer tube 201 to engage with the outer wall of the inner tube 203;

[0066] The screw 204 is disposed in the inner tube 203, and its outer wall is screwed to the inner wall of the inner tube 203;

[0067] The handle 205 is arranged on the outer wall of one end of the screw rod 204 which is away from the inner tube 203 when the screw rod 204 is screwed out;

[0068] The support foot 206 is arranged at an end away from the inner tube 203 when the screw rod 204 is screwed out. With such arrangement, the overall length of the support rod 2 can be roughly adjusted by moving the inner tube 203, and the overall length of the support rod 2 can be finely adjusted by rotating the handle 205 to screw the screw rod 204 in and out of the inner tube 203. Such a scheme can realize the rapid support of the support rod 2 at a nearby support point, and the reverse support of the support point can be used to quickly apply the plugging pressure according to the plugging requirement, thereby realizing rapid plugging of the hull, and the pressure can be quickly adjusted according to the plugging requirement to ensure the plugging effect.

[0069] Furthermore, if Figure 2 As shown, in this embodiment, two sealing grooves 104 are provided on the other surface of the pressure plate 1, and the two sealing grooves 104 are respectively arranged opposite to the two first grooves 1021. In this way, the force-applying end of the support rod 2 hinged in the first groove 1021 can face the sealing structure 3 in the sealing groove 104, so that the force transmission effect of the support rod 2 and the sealing structure 3 can be effectively improved, and the sealing effect of the sealing structure 3 on the damaged part of the ship can be effectively improved.

[0070] Furthermore, if Figure 2 As shown, in this embodiment, the sealing structure 3 is an elastic sealing structure, and when the pressure is transmitted through the support rod 2 and the pressure plate 1, the sealing structure 3 elastically squeezes the damaged part on the ship. Such a configuration can make the effect of squeezing and sealing the damaged part on the ship by the sealing structure 3 better, safer and more reliable, so that the sealing structure 3 will not cause damage to the hull due to excessive pressure, and at the same time can effectively improve the ability to adapt to the structural shape of the damaged part of the hull, that is, improve the ability to adapt to deformation, ensure that it can be squeezed and sealed according to the structural shape of the damaged part, increase the applicable range of the damaged part, and improve the plugging efficiency.

[0071] Furthermore, if Figure 2As shown, in this embodiment, the sealing structure 3 includes: a mounting portion 303, a first support plate 304, a return spring 302, a first limiting structure 305, a second support plate 306 and a first sealing rubber 301;

[0072] The mounting portion 303 is correspondingly mounted in the sealing groove 104 (e.g., a circular groove);

[0073] The first support plate 304 is supported on the surface of the mounting portion facing away from the sealing groove;

[0074] The return spring 302 is supported at the center of the surface of the first support plate 304 away from the mounting portion 303;

[0075] The first limiting structure 305 (for example, a cylindrical structure) is supported on the edges of the first supporting plate 304 on the surface away from the mounting portion 303;

[0076] The second support plate 306 is supported on the return spring 302, and its travel range through the return spring 302 is limited by the first limiting structure 305;

[0077] The first sealing rubber 301 is supported on the surface of the second supporting plate 306 away from the return spring 302, and when the return spring 302 supports the second supporting plate 306 so that the second supporting plate 306 is in contact with the end of the first limiting structure 305, the first sealing rubber 301 protrudes from the end of the first limiting structure 305. In this way, the mounting portion 303 can stably and securely mount the sealing structure 3 in the sealing groove 104, and then the first limiting structure 305 limits the elastic movement range of the second supporting plate 306 and the first sealing rubber 301 driven by the return spring 302, so as to ensure that the elastic movement of the second supporting plate 306 and the first sealing rubber 301 will not deviate from the predetermined range, and ensure that the elastic movement and the plugging achieved by the elastic movement are more accurate and reliable.

[0078] Furthermore, if Figure 2 As shown, in this embodiment, the first limiting structure 305 includes: a first limiting plate 3051 (for example, cylindrical), a baffle 3052 and a second sealing rubber 3053;

[0079] One end of the first limiting plate 3051 is respectively supported on the four edges of the surface of the first supporting plate 304 away from the mounting portion 303;

[0080] The baffle plate 3052 is supported at the other end of the first limiting plate 3051, and one side of the baffle plate 3052 protrudes toward the inner side of the first limiting plate 3051, so as to limit the second supporting plate 306;

[0081] The second sealing rubber 3053 is supported on the surface of the baffle 3052 away from the first limiting plate 3051. In this way, the first limiting plate 3051 can be supported on the surroundings of the return spring 302 and the second support plate 306, and the baffle 3052 can be supported on one side of the second support plate 306. The lateral movement range and the longitudinal movement range of the second support plate 306 are limited by the first limiting plate 3051 and the baffle 3052, so that the first sealing rubber 301 on the second support plate 306 for sealing and plugging can move accurately, and the damaged part on the hull can be accurately elastically sealed, effectively improving the sealing effect. At the same time, the first sealing rubber 301 and the second sealing rubber 3053 can achieve coordinated plugging, and a sealing gap is formed between the two, effectively improving the plugging effect and plugging efficiency.

[0082] Furthermore, if Figure 2 As shown, in this embodiment, the sealing structure 3 further includes: a second limiting structure 307 (such as a limiting cylinder), the second limiting structure 307 is sleeved on the periphery of the return spring 302, and one end of the second limiting structure 307 is fixed on the first support plate 304;

[0083] When the second support plate 306 is contacted and limited by the baffle 3052 of the first limiting structure 305, the height of the second limiting structure 307 is lower than the height of the return spring 302. With such a configuration, the return spring 302 can have space to drive the second support plate 306 to perform elastic movement, so that the return spring 302 can not only be limited by the second limiting structure 307 to avoid deformation beyond the bending deformation range, but also ensure elastic support for the second support plate 306, and ensure the effect of elastic sealing of the damaged part on the ship.

[0084] According to the above scheme of the present invention, the present invention utilizes an integrated marine plugging device to plug the breach to limit water ingress.

When disassembling, rotate the handle in the opposite direction, screw the screw into the inner tube, then press the bayonet to retract the inner tube into the outer tube, and finally fold the support rod into the pressure plate to achieve disassembly and retraction.
