[0001] The present invention relates to the technical field of underwater vehicle pipeline connection, and in particular to a detachable pipeline connection structure. Background Art

[0002] Underwater vehicle piping primarily involves connecting the vessel's water tanks. Water tanks are typically used to store ballast water, fresh water, and sewage, transporting and managing these waters through a piping system. These tanks play a critical role, serving not only to adjust the submarine's buoyancy and balance but also to store domestic water, including drinking water and clean water.

[0003] There are many water tanks in underwater vehicles, and the distribution of their pipelines is also relatively complex. Each water tank has the needs of water supply and pumping. When a pipeline needs to be disassembled and maintained, the flow channel of the pipeline needs to be disconnected and the disassembly and maintenance needs to be carried out. During the disassembly and maintenance process, in order to ensure the normal operation of the water inlet and outlet of the water tank, another pipeline needs to be replaced immediately for water supply and outlet treatment. The operation during the disassembly and replacement of the pipeline is difficult and takes too much time. At the same time, the water inlet and outlet treatment of the water tank still needs to be temporarily suspended when the pipeline is replaced, which affects the normal operation of the water tank.

[0004] The invention, with publication number CN114763864A, proposes a pipe connection structure that facilitates disassembly, comprising a pipe body (I), a pipe body (II) fixedly connected at its right end, a connector fixedly connected to the outer ends of the pipe bodies (I and II), the pipe bodies (I and II) being fixedly connected via the connector, and sealing rings fixedly mounted on the left and right ends of the pipe bodies (I and II).

At this time, the control rack on the undisassembled side moves upward under the action of the control gear, and the control rack drives the connecting rod to move upward along the sliding rod, so that the counterweight sliding ring on that side can realize the rotation adjustment of the rotating shaft without sliding. No matter which side of the connecting pipeline needs to be disassembled and maintained, it is only necessary to adjust the configuration sliding ring on that side to slide downward, which is convenient to use.

[0051] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] like Figures 1 to 14 As shown, the detachable pipe connection structure of the present invention is characterized in that it includes an inlet tee 11, an outlet tee 12, a connecting pipe 2, a rotating shaft 41, a sealing plate 42, a diverter plate 43 and a regulating component 5, wherein the inlet tee 11 includes two water outlet ends, the outlet tee 12 includes two water inlet ends, the two connecting pipes 2 are respectively connected to the two water outlet ends of the inlet tee 11, and are connected to the two water inlet ends of the outlet tee 12; the inlet tee 11 includes a first vertical pipe 111, and a water inlet cavity 114 for water circulation is formed inside the inlet tee 11, and the diverter plate 43 is arranged inside the water inlet cavity 114 and divides the water inlet cavity 114 into two equal volumes The two water inlet channels are respectively connected to the two connecting pipes 2, the end of the diverter plate 43 extends to the inside of the first vertical pipe 111, and the end of the diverter plate 43 is provided with an arc-shaped sealing groove 431; the rotating shaft 41 is rotatably arranged inside the first vertical pipe 111; the sealing plate 42 is fixedly connected to the rotating shaft 41, and the sealing plate 42 is a semicircular plate, and a sealing gasket is provided on the side wall of the sealing plate 42. When the rotating shaft 41 rotates, the sealing plate 42 rotates to block half of the flow cavity of the first vertical pipe 111. The width of the sealing plate 42 is smaller than the diameter of the rotating shaft 41. The rotating shaft 41 is located on the inner side of the sealing groove 431 and is sealed with the sealing groove 431; the regulating component 5 is used to regulate the rotation of the rotating shaft 41.

[0053] In practice, the inlet tee 11 and outlet tee 12 are similar to existing tee designs. During normal water supply through the pipeline connection structure of the present application, the sealing plate 42 and the diverter plate 43 are both in a vertical position. Water flows from the first vertical pipe 111 into the inlet tee 11 and, under the diversion effect of the sealing plate 42 and the diverter plate 43, flows into the interiors of the two connecting pipes 2 respectively, and then flows out through the connecting pipes 2 and converges at the outlet tee 12.

[0054] When it is necessary to disassemble and maintain the connecting pipe 2 on one side, the regulating component 5 is used to regulate the rotating shaft 41 to rotate toward the connecting pipe 2 on that side. At this time, the rotating shaft 41 drives the sealing plate 42 to rotate. When the rotating shaft 41 rotates ninety degrees, the sealing plate 42 is sealed with the pipe wall of the first vertical pipe 111 under the action of the sealing gasket on its surface. At this time, the sealing plate 42 can block the water flow and cooperate with the diverter plate 43 to guide the water flow to the side of the connecting pipe 2 that has not been disassembled. At this time, the connecting pipe 2 to be maintained can be disassembled, and during the disassembly and maintenance, the blocking effect of the sealing plate 42 can prevent the water from flowing out of the disassembled connecting pipe 2, thereby preventing waste of resources.

[0055] During the disassembly and maintenance of the connecting pipe 2 on one side, water flows through the connecting pipe 2 that has not been disassembled, which can ensure the water flow requirements of the water tank. At the same time, when the connecting pipe 2 is disassembled for maintenance, there is no need to immediately connect a new connecting pipe 2, which simplifies the complexity of the disassembly and maintenance steps of the connecting pipe 2, facilitates the disassembly and maintenance of the connecting pipe 2, and is convenient for use.

[0056] It should be noted that the present application also allows the outlet tee 12 to be detached. In this case, the inlet tee 11 can be used as a new tee in conjunction with the two connecting pipes 2, thereby improving the applicability of use.

[0057] As a preferred embodiment, the regulating component 5 includes a regulating gear 51 and two regulating racks 52, wherein the end of the rotating shaft 41 passes through and extends to the outside of the first vertical tube 111, and the regulating gear 51 is fixedly connected to the end of the rotating shaft 41; the two regulating racks 52 are respectively located on opposite sides of the regulating gear 51 and mesh with the regulating gear 51.

[0058] It also includes a counterweight sliding ring 61, and the regulating component 5 also includes a connecting rod 53 and a sliding rod 54, wherein the connecting rod 53 is fixedly connected to the regulating rack 52, and the sliding rod 54 is slidingly connected to the connecting rod 53; the counterweight sliding ring 61 is slidingly arranged relative to the water inlet tee pipe 11, and has the same sliding path as the sliding rod 54, and the counterweight sliding ring 61 is fixedly connected to the sliding rod 54.

[0059] The water inlet tee 11 also includes two diverter pipes 112 and two second vertical pipes 113, wherein the two diverter pipes 112 are connected to the water outlet end of the first vertical pipe 111, and the diverter plate 43 is arranged at the connection between the two diverter pipes 112 and the first vertical pipe 111; the two second vertical pipes 113 are respectively connected to the two diverter pipes 112, and the counterweight sliding ring 61 is slidably sleeved on the second vertical pipe 113. The second vertical pipe 113 has the same extension direction as the first vertical pipe 111, and the water outlet tee 12 has the same shape as the water inlet tee 11.

[0060] When the water flows through the connecting pipes 2 on both sides, the regulating gear 51 is located in the middle position of the two regulating racks 52, and the sliding rod 54 is slidably connected to the deepest position of the connecting rod 53. At this time, the sliding rod 54 conflicts with the counterweight sliding ring 61.

[0061] When it is necessary to maintain the connecting pipe 2 on that side, the counterweight slide ring 61 on that side is adjusted to slide downward. At this time, the counterweight slide ring 61 first drives the sliding rod 54 to slide along the connecting rod 53. After the sliding rod 54 slides downward to the maximum distance, the sliding rod 54 drives the connecting rod 53 to move downward together. The connecting rod 53 drives the regulating rack 52 on this side to move downward and drives the regulating gear 51 to rotate, thereby completing the rotation adjustment processing of the rotating shaft 41. At this time, the regulating rack 52 on the other side moves upward under the action of the regulating gear 51, and the regulating rack 52 drives the connecting rod 53 to move upward along the sliding rod 54, so that the counterweight slide ring 61 on this side can realize the rotation adjustment processing of the rotating shaft 41 without sliding. No matter which side of the connecting pipe 2 needs to be disassembled and maintained, it is only necessary to adjust the configuration slide ring 61 on that side to slide downward, which is convenient to use.

[0062] It should be noted that the diverter pipe 112 is an arc-shaped curved pipe to reduce energy consumption when water flows through the diverter pipe 112 .

[0063] As a preferred embodiment, the two water outlet ends of the water inlet tee 11 are respectively provided with two first assembly flanges 311, the two water inlet ends of the water outlet tee 12 are respectively provided with second assembly flanges 312, and the two ends of the connecting pipe 2 are respectively provided with a first connecting flange 321 and a second connecting flange 322, the first connecting flange 321 and the first assembly flange 311 are detachably connected, and the second connecting flange 322 and the second assembly flange 312 are detachably connected.

[0064] It also includes a push rod 62 , wherein a limiting hole 3111 is opened on the first assembly flange 311 ; the push rod 62 is arranged on the first connecting flange 321 and passes through the limiting hole 3111 to abut against the counterweight sliding ring 61 .

[0065] In a specific implementation, the connection between the connecting pipe 2 and the water inlet tee 11 and the water outlet tee 12 is completed by connecting the connecting flange and the assembly flange. When the first connecting flange 321 is connected to the first assembly flange 311, the push rod 62 passes through the limiting hole 3111 and slides along the limiting hole 3111. At this time, under the limitation of the push rod 62, it is used to increase the stability of the connection of the first connecting flange 321. The push rod 62 contacts the counterweight sliding ring 61 and pushes the counterweight sliding ring 61 to move upward. After the first connecting flange 321 is connected to the first assembly flange 311, the counterweight sliding ring 61 slides to the top. At this time, the sliding rod 54 slides to the inside of the connecting rod 53. The connecting rod 53 contacts the counterweight sliding ring 61. Under the limitation of the two connecting rods 53, the regulating gear 51 is located in the middle position of the regulating rack 52, and one of the regulating racks 52 cannot overcome the limitation of the connecting rod 53 and move upward alone. In this way, the push rod 62 plays a role in supporting and positioning the counterweight sliding ring 61.

[0066] In this way, when it is necessary to disassemble and maintain the connecting pipe 2 on one side, it is first necessary to disassemble the first connecting flange 321 connected to the first assembly flange 311. At this time, the push rod 62 moves along the limiting hole 3111 and gradually disengages from the first assembly flange 311. As the push rod 62 moves, the counterweight sliding ring 61 also gradually slides downward under the action of its own gravity. In this way, after the connecting pipe 2 is completely disassembled, the counterweight sliding ring 61 also naturally slides down to conflict with the first assembly flange 311. At this time, the control rack 52 corresponding to the counterweight sliding ring 61 on this side moves downward accordingly, and the control gear 51 is driven to rotate, thereby completing the adjustment of the sealing plate 42. The rotation and adjustment of the sealing plate 42 are convenient. After the connecting pipe 2 that needs maintenance is disassembled, the sealing plate 42 automatically turns to the side of the disassembled connecting pipe 2 and seals it. No additional force is required to rotate and adjust the rotating shaft 41, which is convenient to use.

[0067] As a preferred embodiment, when the first connecting flange 321 is connected to the first assembly flange 311, the distance between the counterweight slide ring 61 and the first assembly flange 311 is a, the maximum distance that the sliding rod 54 slides outward relative to the connecting rod 53 is b, the length of the regulating rack 52 is c, and the relationship between a, b, and c is: b<a<2b<c.

[0068] With this design, when disassembling the connecting pipe 2, the counterweight sliding ring 61 on the corresponding side first drives the sliding rod 54 to move a distance b along the connecting rod 53. At this time, the sliding rod 54 slides to the maximum distance. Since a>b, the counterweight sliding ring 61 can carry the sliding rod 54 and the connecting rod 53 to drive the corresponding regulating rack 52 to move downward. At this time, the connecting rod 53 on the other side slides upward along the sliding rod 54. Since a<2b, the counterweight sliding ring 61 can slide smoothly to the bottom. At this time, the regulating gear 51 drives the rotating shaft 41 to rotate 90 degrees toward the disassembly side, and the sealing plate 42 completes the blocking of the water inlet channel on the disassembly side. Since the regulating gear 51 is located in the middle of the regulating rack 52 during normal water supply, by setting c>2b, when the counterweight sliding ring 61 slides and is aligned with the first assembly flange 311, the counterweight sliding ring 61 can drive the regulating rack 52 to move and drive the regulating gear 51 to rotate.

[0069] As a preferred embodiment, the connecting pipe 2 includes a fixed pipe 21 and a sliding pipe 22 that are slidably connected to each other, wherein the first connecting flange 321 is arranged at the end of the sliding pipe 22, and the second connecting flange 322 is arranged at the end of the fixed pipe 21.

[0070] With this design, when the connecting pipe 2 is disassembled and maintained, the sliding pipe 22 is adjusted to slide along the fixed pipe 21, so that the top cover 62 can slide smoothly along the limiting hole 3111 and detach from the first assembly flange 311, thereby facilitating the disassembly of the connecting pipe 2.

[0071] As a preferred embodiment, it also includes a clamping component 7, wherein the clamping component 7 is arranged on the counterweight slide ring 61, and when the counterweight slide ring 61 slides to conflict with the first assembly flange 311, the clamping component 7 is used to locate the sliding position of the counterweight slide ring 61.

[0072] The clamping component 7 includes a positioning block 71 and a spring 72, wherein a mounting groove 611 is provided on the inner side of the counterweight slide ring 61, and the positioning block 71 is slidably arranged inside the mounting groove 611, and a positioning groove 1131 for the positioning block 71 to be inserted is provided on the outer side of the second vertical tube 113, and the positioning block 71 is an arc-shaped block; the spring 72 conflicts with the positioning block 71 and the mounting groove 611, and is used to reset the sliding position of the positioning block 71.

[0073] In the specific implementation, when the counterweight slide ring 61 slides under its own gravity until it conflicts with the first assembly flange 311, the side wall of the second vertical pipe 113 can squeeze the positioning block 71 and cause the spring 72 to contract. When the counterweight slide ring 61 slides under its own gravity until it conflicts with the first assembly flange 311, the positioning block 71 is relative to the positioning slot 1131. At this time, the spring 72 resets and pushes the positioning block 71 to be inserted into the inside of the positioning slot 1131. Since the positioning block 71 is an arc-shaped block, the simple positioning processing of the counterweight slide ring 61 can be completed under the restriction of the positioning block 71 to prevent the counterweight slide ring 61 from accidentally sliding upward, thereby increasing the stability of the sealing plate 42 in blocking the water flow when the connecting pipe 2 is disassembled.

[0074] The working principle of the present invention is described below:

[0075] Specifically, when water is supplied in the present application, the sealing plate 42 and the diverter plate 43 are also in a vertical state, and the water flows into the water inlet tee 11 from the first vertical pipe 111, and under the diverting action of the sealing plate 42 and the diverter plate 43, flows into the interior of the two connecting pipes 2 through the two diverter pipes 112 and the second vertical pipe 113 respectively, and flows out after being collected at the water outlet tee 12 through the connecting pipe 2. When it is necessary to disassemble and maintain the connecting pipe 2 on one side, the connecting pipe 2 on that side is directly disassembled. During disassembly, the connecting rod 53 needs to be adjusted to move downward to disengage from the first assembly flange 311. As the top rod 62 moves, the counterweight sliding ring 61 gradually slides downward under the action of its own gravity. In this way, after the connecting pipe 2 is completely disassembled, the counterweight sliding ring 61 naturally slides down to conflict with the first assembly flange 311. When disassembling the connecting pipe 2, the counterweight sliding ring 61 on the corresponding side first drives the sliding rod 54 to move a distance b along the connecting rod 53. At this time, the sliding rod 54 slides to the maximum distance. Since a>b, this At this time, the counterweight sliding ring 61 can carry the sliding rod 54 and the connecting rod 53 to drive the corresponding regulating rack 52 to move downward. At this time, the connecting rod 53 on the other side slides upward along the sliding rod 54. Since a<2b, the counterweight sliding ring 61 can slide smoothly to the bottom. At this time, the regulating gear 51 drives the rotating shaft 41 to rotate ninety degrees toward the disassembly side. The sealing plate 42 is sealed with the pipe wall of the first vertical pipe 111 under the action of the sealing gasket on its surface. At this time, the sealing plate 42 can block the water flow and cooperate with the diverter plate 43 to guide the water flow to the side of the connecting pipe 2 that has not been disassembled. At this time, the connecting pipe 2 to be maintained can be disassembled.

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