Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and in particular to a leak-proof device for water pipes in construction projects. Background Technology

[0002] Construction engineering refers to the systematic process of transforming design drawings into actual buildings, encompassing various types such as residential, commercial, and infrastructure. During construction, the installation of various pipelines is crucial, with water pipe laying being particularly critical. Water pipes are divided into multiple systems, including water supply, drainage, and fire protection, and their layout must strictly adhere to specifications to ensure safe water supply and unobstructed drainage.

[0003] When water pipes leak, the traditional repair method usually involves using a leak-stopping device. A leak-stopping device is a common pipe repair tool that stops the leak by applying pressure at the leak point. However, the installation process is quite cumbersome, requiring multiple bolts to be fixed to the leak-stopping device and tightened one by one to ensure a tight seal between the device and the pipe, preventing secondary leakage. This is not only time-consuming and labor-intensive but also requires a high level of skill from the installer. Uneven bolt tension can lead to poor sealing and even affect the overall stability of the pipeline. Utility Model Content

Detailed Implementation

[0018] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] A leak-proof device for water pipes in construction projects, such as Figures 1-5 As shown, the device includes a first fixing ring 1, a second fixing ring 2, a fixing assembly, a third fixing seat 6, a fourth fixing seat 7, a rotating shaft 8, a fixing belt 9, a turntable 11, a connecting ring 12, a plug 10, a plastic bag 17, and a needle 18. The first fixing ring 1 is connected to the fixing assembly, and the first fixing ring 1 is connected to the second fixing ring 2 via the fixing assembly. The first fixing ring 1 is connected to the third fixing seat 6, and the second fixing ring 2 is connected to the fourth fixing seat 7. The fourth fixing seat 7 is rotatably connected to the rotating shaft 8, and the fixing belt 9 is wound around the rotating shaft 8. The third fixing seat 6 is rotatably connected to the turntable 11, one end of which is fixedly connected to the rotating shaft 8. The turntable 11 has a slot 111 that matches the fixing belt 9. The other end of the fixed belt 9 is engaged with the turntable 11 via the slot 111. A rotating component is connected to the turntable 11. A connecting ring 12 is connected to the side of the turntable 11 away from the third fixed seat 6. The outer diameter of the connecting ring 12 is larger than the outer diameter of the turntable 11. The connecting ring 12 can prevent the fixed belt 9 from slipping off the turntable 11 during winding. A plug 10 is inserted into the turntable 11. The plug 10 passes through the turntable 11 and can fix the fixed belt 9 on the turntable 11 to prevent the fixed belt 9 from slipping off the turntable 11. A groove 16 is opened on the inner wall of the second fixed ring 2. A plastic bag 17 is connected in the groove 16. The plastic bag 17 is filled with sealant. At least five needles 18 are connected circumferentially on both sides of the groove 16.

[0020] like Figure 1 As shown, the fixing assembly includes a first fixing seat 3, a second fixing seat 4, and a rubber block 5. The second fixing seat 4 is connected to the first fixing ring 1, and the first fixing seat 3 is connected to the second fixing ring 2. The rubber block 5 is connected between the first fixing seat 3 and the second fixing seat 4. The flexible rubber block 5 enables this leak-proof device to be suitable for leak-proof treatment of water pipes with various outer diameters.

[0021] like Figures 1-3As shown, the rotating assembly includes a spring 19, a rotating block 13, a fixed block 14, and a plug rod 15. The rotating block 13 is connected to the connecting ring 12 and is fixedly connected to the turntable 11. A regular hexagonal groove 131 is opened in the middle of the rotating block 13. At least two fixed blocks 14 are connected to the rotating block 13 at intervals along the circumference. The side of the fixed block 14 away from the rotating block 13 is slidably connected to the plug rod 15. At least twenty insertion holes 61 are opened to the third fixed seat 6 at intervals along the circumference. The plug rod 15 is inserted into the third fixed seat 6 through the insertion holes 61. A spring 19 is connected between the plug rod 15 and the fixed block 14.

[0022] Initially, the fixing band 9 is disengaged from the slot 111, the insertion rod 15 is disengaged from the third fixing block 14, the spring 19 is in its natural state, and the insertion rod 15 is inserted into the insertion hole 61. When using this leak-proof device, first, the first fixing ring 1 and the second fixing ring 2 are placed on the water pipe, so that the second fixing ring 2 covers the leaking position of the water pipe. Then, the end of the fixing band 9 away from the rotating shaft 8 is inserted into the slot 111, and then the insertion bolt 10 is inserted into the turntable 11, so that the insertion bolt 10 passes through the fixing band 9, thereby fixing both ends of the fixing band 9. The sliding insertion rod 15 then... When it disengages from the socket 61, the spring 19 is stretched, and then a tool is inserted into the regular hexagonal slot 131 to make the rotating block 13 rotate counterclockwise, causing the fixing block 14 to drive the turntable 11 to rotate counterclockwise. The fixing band 9 is released from the rotating shaft 8 until the rotating shaft 8 can no longer rotate, the fixing band 9 is in a taut state, and the fixing band 9 is wound onto the turntable 11, thereby making the first fixing ring 1 and the second fixing ring 2 tightly adhere to the outer wall of the water pipe, mechanically sealing the water pipe leakage point. When the first fixing ring 1 and the second fixing ring 2 are tightly attached to the water pipe... After fitting, align the insert rod 15 with the socket 61, release the insert rod 15, and the spring 19 returns to its original state, allowing the insert rod 15 to be inserted into the socket 61, thereby fixing the rotating block 13. The turntable 11 can no longer rotate, and the fixing band 9 remains taut. Under the action of the first fixing ring 1 and the second fixing ring 2, the leak in the water pipe is sealed. At this time, the plastic bag 17 is squeezed and deformed. Both sides of the plastic bag 17 are close to the needle 18. The needle 18 punctures the plastic bag 17, causing the sealant to leak out, thus allowing it to be sealed by the second fixing ring. 2. Fill the gap between the water pipe and the leaking point with sealant to perform secondary leak prevention treatment on the leaking point of the water pipe. It can also fill the small gaps between the first fixing ring 1 and the second fixing ring 2 and the water pipe, forming a double leak prevention mechanism to improve the leak prevention effect. When it is necessary to disassemble this leak prevention device to replace the water pipe, pull out the plug 15 from the plug hole 61, then rotate the rotating shaft 8 to release the fixing band 9 from the turntable 11, then pull out the plug 10, remove the fixing band 9 from the turntable 11, and then remove this leak prevention device from the water pipe.
