Description
Technical Field
[0001] This utility model specifically relates to a clamshell sealing and isolation device for blocking pipelines, belonging to the field of pipeline blocking application technology. Background Technology
[0002] A pipeline is a system of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. It is typically used to move pressurized fluids from high-pressure areas to low-pressure areas, or it can utilize the fluid's own pressure or gravity for transport. Pipelines have a wide range of applications, including water supply, drainage, heating, gas supply, long-distance oil and natural gas transportation, agricultural irrigation, hydraulic engineering, and various industrial installations. "Pipeline blocking" typically refers to taking measures within a pipeline system to cut off and block the flow of water or other fluids to a specific area. In waterproofing projects, interception and blocking are two crucial elements that together constitute part of the waterproofing system, ensuring the dryness and safety of the structure.
[0003] An existing patent application (CN202323407825.9) discloses a clamshell sealing isolation device for temporarily blocking pipelines, aiming to address the problems of large size, high installation difficulty, and high construction cost of existing equipment. This device includes a main support, a sealing assembly, an adjusting assembly, and a docking assembly. The sealing assembly includes side baffles and a middle baffle. The sealing assembly has a first state and a second state. In the first state, the adjusting assembly contracts, causing the side baffles to retract towards the main support. In the second state, the adjusting assembly extends, causing the side baffles to open away from the main support, so that the side baffles and the middle baffle form a circular surface. The side baffles of the sealing assembly fold on both sides of the main support, reducing the vertical projection size of the sealing assembly, thus reducing the size of the pre-drilled holes in the pipeline, lowering the construction difficulty and cost.
[0004] The above-mentioned device improves the convenience of construction. However, a single-layer baffle can easily cause pipe blockage and leakage, and the structure is relatively complex and not convenient to disassemble and assemble. Utility Model Content

[0025] The arc-shaped fitting plate 1 fits against the inner surface of the external pipe, meaning that the arc-shaped fitting plate 1 is designed to match the internal shape of the pipe to ensure that the device can fit tightly against the inner wall of the pipe and form an effective seal. This design helps to prevent fluid or gas leakage in the pipe. Rotary mounting holes are opened on both ends of the arc-shaped fitting plate 1, and rotating mounting shafts are designed on both ends of the sealing adjustment plate 3. The rotating mounting shafts and rotating mounting holes are mutually engaged, allowing the sealing adjustment plate 3 to be rotated and adjusted on the arc-shaped fitting plate 1 to adapt to different sealing requirements. This design not only improves the flexibility of the device but also helps to ensure the stability and reliability of the sealing effect.
[0026] A rotating connecting frame 301 is fixedly welded to one side of the sealing adjustment plate 3, serving as a rotating connection point between the supporting adjustment plate 4 and the sealing adjustment plate 3. One end of the supporting adjustment plate 4 is rotatably connected to the rotating connecting frame 301. This connection method allows the supporting adjustment plate 4 to rotate to a certain extent within the rotating connecting frame 301, thereby adjusting its relative position with the arc-shaped fitting plate 1 and the sealing adjustment plate 3. Mirror transition grooves are provided on both sides of the rotating connecting plate 5, and the mirror transition grooves are rotatably engaged with the other end of the supporting adjustment plate 4. This connection method not only allows the supporting adjustment plate 4 to rotate on the rotating connecting plate 5, but also ensures the stability and reliability of the rotation.
[0027] The rotating connecting plate 5 includes a front adjusting mounting plate 501 and a rear adjusting mounting plate 502. One end of each rotating connecting plate 5 is provided with an adjusting threaded hole. The adjusting threaded hole and the adjusting threaded rod 7 are threadedly connected to each other. This threaded connection method allows the position of the rotating connecting plate 5 to be adjusted by rotating the adjusting threaded rod 7, thereby changing the angle and position of the supporting adjusting plate 4 and the sealing adjusting plate 3. The adjusting threaded hole is located on the upper side of the front adjusting mounting plate 501 and on the lower side of the rear adjusting mounting plate 502, which facilitates the adjustment of the working state of the sealing adjusting plates 3 at both ends of the device.
[0028] The mounting structure 9 includes a sealing collar 901, a connecting rod 902, and an operating handle 903. The sealing collar 901 is fitted onto the outside of the mounting threaded pipe 8, the connecting rod 902 is located on the inside of the sealing collar 901, and the operating handle 903 is installed on the outside of the sealing collar 901 to assist in the assembly and disassembly of the device. The sealing collar 901 and the mounting threaded pipe 8 are slidably engaged with each other. A connecting groove is provided on the inside of the sealing collar 901, and the connecting rod 902 is fixedly welded to the inside of the connecting groove. Connecting grooves are evenly provided around the mounting threaded pipe 8, and the connecting rod 902 and the connecting groove are slidably engaged with each other, making it convenient for the user to push the device to rotate, thereby making the device more flexible in assembly and disassembly.
[0029] The sealing structure 10 includes a fixed threaded tube 101 and a sealing rubber ring 102. The fixed threaded tube 101 is fitted onto the outside of the mounting threaded tube 8, and the sealing rubber ring 102 is disposed on the outside of the fixed threaded tube 101. The fixed threaded tube 101 and the mounting threaded tube 8 are threaded together to ensure a tight fit between them, thereby preventing media leakage. The sealing rubber ring 102 and the fixed threaded tube 101 are tightly fixed and adhered to each other. The sealing rubber ring 102 is usually made of soft and durable rubber material to ensure good sealing between it and the pipeline.
