Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering pipeline technology, and in particular to an impact-resistant socket connection device for water conservancy engineering pipelines. Background Technology

[0002] In water conservancy projects, pipeline systems are a crucial component for transporting water, regulating water flow, and ensuring the safe operation of the project. Pipeline systems typically consist of various components such as straight pipes, bends, valves, and connectors. These components require reliable connections to achieve sealing and stable connections. The stability and sealing of these connections are particularly important at locations where pipes of different angles or diameters need to be connected, such as the joints between bends and connecting pipes.

[0003] Traditional pipe connection methods, such as welding and flange connections, while possessing a certain degree of strength and sealing, have limitations in certain specific scenarios. For example, on construction sites, the size and angle of pipes may deviate from their intended purpose, or fine-tuning may be required based on actual site conditions. Traditional rigid connection methods often struggle to adapt to these changes, potentially leading to connection difficulties, inadequate sealing, or the need for pipe cutting and reprocessing, increasing construction difficulty and costs. Furthermore, during operation, hydraulic engineering pipeline systems are subject to various factors such as water flow impact, temperature changes, and foundation settlement, resulting in vibration and displacement. If the connection points lack effective protection and restraint measures, prolonged vibration may lead to loosening of connections, seal failure, and even pipe rupture and leakage, seriously affecting the safe and stable operation of the project.

[0004] To address the above problems, it is necessary to design an impact-resistant socket connection device for water conservancy engineering pipelines to overcome these issues. Utility Model Content

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-6 As shown, an impact-resistant socket connection device for water conservancy engineering pipelines includes a curved protective frame 1, a clamping sleeve 2, a bend 3, and a connecting pipe 4. One end of the top of the curved protective frame 1 is provided with an adjustment groove 5. The top end of the curved protective frame 1 near the adjustment groove 5 is connected to a first limiting frame 6 and a second limiting frame 7, respectively. An adjustment block 9 is connected to the inner side of the adjustment groove 5. One end of the adjustment block 9 is connected to a support rod 10. The end of the support rod 10 away from the adjustment block 9 is connected to an upper docking ring 11. One end of the top of the upper docking ring 11 is fixedly connected to a first dust collection box 12. The top of the first dust collection box 12 is connected to an installation frame 13. One end of the installation frame 13 is provided with a dust suction port 14. The top of the second limiting frame 7 is provided with a moving groove 8. The end of the installation frame 13 away from the second limiting frame 7 is fixedly connected to a connecting plate 15. One end of the connecting plate 15 is connected to an installation rod 16. The end of the installation rod 16 away from the connecting plate 15 is connected to a first arc-shaped anti-collision pad 17.

[0026] The curved protective frame 1 is fixedly connected to the clamping sleeve 2. The curved protective frame 1 is sleeved on the outer wall of the curved pipe 3. The curved protective frame 1 is threadedly fixedly connected to the first limiting frame 6 and the second limiting frame 7. The adjusting block 9 is slidably connected in the adjusting groove 5. The adjusting block 9 is rotatably connected to the support rod 10. The support rod 10 is rotatably connected to the upper docking ring 11. The first dust collection box 12 is movably connected to the inside of the mounting frame 13 through the connecting pipe. The bottom of the upper docking ring 11 contacts the connection between the curved pipe 3 and the connecting pipe 4. The connecting plate 15 is threadedly fixedly connected to the mounting rod 16. The mounting rod 16 is rotatably connected to the first arc-shaped anti-collision pad 17. The inner side of the first arc-shaped anti-collision pad 17 contacts the outer wall of the connecting pipe 4.

[0027] Specifically, the curved protective frame 1 has an arc-shaped structure, the curvature of which matches the shape of the bend 3, and is used to fit over the outside of the bend 3. One end of the curved protective frame 1 is fixedly connected to the clamping sleeve 2 by a thread. The clamping sleeve 2 is fitted onto the bend 3 near the connection end and is fixed to the bend 3 by bolts or other fastening methods to ensure that the position of the entire equipment relative to the bend 3 is stable. An adjustment groove 5 is provided on the curved protective frame 1 or its extension structure. The adjustment block 9 can slide freely in the adjustment groove 5 along the length of the groove. One end of the support rod 10 is fixedly connected to the adjustment block 9, and the other end is connected to the upper docking ring 11. By moving the position of the adjustment block 9 in the adjustment groove 5, the length or angle of the support rod 10 can be changed, thereby driving the upper docking ring 11 to make precise up-down and left-right adjustments in the docking area between the bend 3 and the connecting pipe 4. The inner diameter of the upper docking ring 11 is designed to be slightly larger than the outer diameter of the end of the bend 3 so that it can be smoothly fitted over the end of the bend 3 when the pipe is connected.

[0028] A movable groove 8 is provided on the curved protective frame 1 or the first limiting frame 6. A slider is provided at the bottom of the mounting frame 13, which slides in cooperation with the movable groove 8, allowing the mounting frame 13 to move back and forth within the movable groove 8. A connecting plate 15 is fixed above or to the side of the mounting frame 13. A mounting rod 16 fixes the first arc-shaped anti-collision pad 17 to the connecting plate 15, allowing the first arc-shaped anti-collision pad 17 to be adjusted at a certain angle according to the diameter of the connecting pipe 4. A dust suction port 14 is provided inside the mounting frame 13 or on the structure connected to it, for sucking up dust and impurities from the connection end of the connecting pipe 4. A fan 20 is connected to the dust suction port 14 inside the mounting frame 13 through a pipe, providing power for dust suction. When the fan 20 is working, air is sucked in through the dust suction port 14, carrying away the dust from the connection end of the connecting pipe 4. Since the position of the upper connecting ring 11 is adjustable, the mounting frame 13, its dust suction port 14, and the first arc-shaped anti-collision pad 17 follow the movement of the upper connecting ring 11, always aligning with the end of the connecting pipe 4 to be connected for cleaning.

[0029] The end of the first limiting frame 6 away from the curved protective frame 1 is connected to a fixed frame 18 via a slider. The inner side of the fixed frame 18 is provided with a dust suction port 14. The bottom of the fixed frame 18 near the first limiting frame 6 is fixedly connected to a second dust collection box 19. One end of the second dust collection box 19 is connected to a fan 20. One end of the second dust collection box 19 is connected to a lower connecting ring 21. The inner side of the fixed frame 18 is provided with a dust suction port 14. One end of the fixed frame 18 is fixedly connected to a fixed plate 22. One end of the fixed plate 22 is connected to a second arc-shaped anti-collision pad 23.

[0030] The fixed frame 18 is slidably connected to the first limiting frame 6 via a bottom slider in a groove. The second dust collection box 19 is movably connected to the inside of the fixed frame 18 via a connecting pipe. The inner side of the lower connecting ring 21 contacts the connection between the bend pipe 3 and the outer wall of the connecting pipe 4. The second dust collection box 19 and the lower connecting ring 21 are rotatably connected via a connecting rod. The fixed plate 22 is rotatably connected to the two second arc-shaped anti-collision pads 23. The two second arc-shaped anti-collision pads 23 are in contact with one end of the connecting pipe 4.

[0031] Specifically, the first limiting frame 6 is located on the side of the curved protective frame 1 away from the connecting end of the curved pipe 3, and a sliding groove is provided on it. The bottom of the fixed frame 18 is provided with a slider, which slides in cooperation with the sliding groove on the first limiting frame 6, allowing the fixed frame 18 to move within the sliding groove. A dust suction port 14 is provided on the inner side wall of the fixed frame 18, which functions similarly to the dust suction port 14 on the mounting frame 13, and is used to clean the other side of the connection between the curved pipe 3 and the connecting pipe 4. A second dust collection box 19 is fixedly connected to the bottom of the fixed frame 18 near the first limiting frame 6. One end of the second dust collection box 19 is connected to the fan 20 through a pipe, and the other end is rotatably connected to the lower docking ring 21 through a connecting rod. The inner diameter of the lower docking ring 21 is designed to be slightly larger than the outer diameter of the connecting pipe 4. The fixed frame 18 is used to fit over the end of the connecting pipe 4 after the connection is completed. One end of the fixed frame 18 is fixedly connected to the fixed plate 22. One end of the fixed plate 22 is connected to two second arc-shaped anti-collision pads 23 by a rotating connection. The two second arc-shaped anti-collision pads 23 are symmetrically distributed on both sides of the fixed plate 22. Their arc surface is designed to fit the outer wall of the connecting pipe 4. By moving the position of the fixed frame 18 in the sliding groove of the first limiting frame 6, the relative position of the lower docking ring 21 and the two second arc-shaped anti-collision pads 23 can be adjusted. When the fixed frame 18 moves, the lower docking ring 21 and the second arc-shaped anti-collision pads 23 move accordingly, working together with the upper docking ring 11 and the first arc-shaped anti-collision pad 17 to achieve all-round support and protection for the connection part of the bend pipe 3 and the connecting pipe 4.

[0032] It should be noted that this utility model is an impact-resistant socket connection device for water conservancy engineering pipelines. In use, the operator manually pushes the adjusting block 9 to slide in a specific direction in the adjusting groove 5 according to the actual size difference between the bend 3 and the connecting pipe 4. The movement of the adjusting block 9 is transmitted through the support rod 10 connected to it. The support rod 10 and the upper connecting ring 11 are usually rotatably connected. This allows the upper connecting ring 11 to adjust its height or angle relative to the docking position of the bend 3 and the connecting pipe 4 as needed when the adjusting block 9 moves. The design of the adjusting groove 5 ensures the guiding and limiting nature of this movement. The upper connecting ring 11 can be accurately moved to a position suitable for the socket docking of the bend 3 and the connecting pipe 4, providing precise guidance and support for subsequent pipeline connections.

[0033] During the adjustment of the upper docking ring 11, the first dust collection box 12 fixed to its top and the mounting frame 13 connected to the top of the first dust collection box 12 will move synchronously. The slider at the bottom of the mounting frame 13 slides in the moving groove 8, ensuring that the mounting frame 13 can smoothly follow the upper docking ring 11, so that the suction port 14 on the mounting frame 13 can be accurately aligned with the end face area where the bent pipe 3 and the connecting pipe 4 are about to be docked. The operator starts the fan 20, which is connected to the second dust collection box 19 through the connecting pipe. The dust collection box 19 is connected to the inside of the mounting frame 13 through the connecting pipe. Air is drawn in from the dust suction port 14 on the mounting frame 13 and the fixed frame 18, and is drawn away by the fan 20 through the channel. Dust and debris are collected through the second dust collection box 19. While the upper docking ring 11 is positioned, the dust suction device performs powerful dust suction on the docking end face of the bent pipe 3 and the connecting pipe 4 to ensure that the docking surface is clean. After the upper docking ring 11 is guided and cleaned, the operator performs the socket connection operation of the bent pipe 3 and the connecting pipe 4 to connect the two tightly.

[0034] After the pipe connection is completed, the operator adjusts the position of the fixing frame 18 as needed. The fixing frame 18 slides in the groove of the first limiting frame 6 through the slider at its bottom to achieve position adjustment. This movement also moves the lower docking ring 21 and the two second arc-shaped anti-collision pads 23 fixed on the lower inner side of the fixing frame 18 to the appropriate position. The movement of the fixing frame 18 and the position of the upper docking ring 11 and the first arc-shaped anti-collision pad 17 form a coordinated relationship, jointly providing support for the connection part of the bend 3 and the connecting pipe 4. By adjusting the length and position of the connecting plate 15 and the mounting rod 16, the first arc-shaped anti-collision pad 17 fixed on the connecting plate 15 is tightly attached to the outer wall of the connecting pipe 4. The first arc-shaped anti-collision pad 17 and the two second arc-shaped anti-collision pads 23 work together through the fixing plate 22 and the rotating connection to limit and clamp the outer wall of the connecting pipe 4. This allows the connecting pipe 4 to be tightly wrapped, restricting its displacement in the radial direction and a certain axial direction. When the bend 3 or connecting pipe 4 vibrates due to factors such as water flow impact and temperature changes during operation, the first arc-shaped anti-collision pad 17 and the second arc-shaped anti-collision pad 23 can absorb part of the vibration energy, preventing the connection part from loosening or misaligning due to vibration, thus playing an effective protective role and ensuring the long-term stability and safety of the pipeline connection.
