Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline technology, specifically a thermal pipeline repair device. Background Technology

[0002] During long-term operation, urban heating pipe networks often experience leaks or localized damage due to aging, corrosion, mechanical damage, or joint wear. Traditional repair methods mostly rely on cutting and replacing pipe sections or welding repairs after the pipeline supply is shut down, which is time-consuming, costly, and carries certain safety risks.

[0003] While some existing heating pipeline repair devices can achieve external fixation, they typically rely on a single-layer clamp or simple compression structure, resulting in poor sealing, limited pressure resistance, complex construction, and insufficient adaptability. These limitations make it difficult to meet the rapid repair needs of urban pipeline networks in emergency situations. Therefore, there is an urgent need for a heating pipeline repair device that can be temporarily installed in emergencies, is easy to operate, and provides both robust protection and sealing, ensuring the safe and stable operation of pipelines before long-term maintenance or replacement.

The number of first fixing structures is multiple, and the first fixing structures are evenly installed on the outside of the repair patch. The second fixing structure is installed on the outside of the first fixing structure, and the number of first fixing structures is multiple. The second fixing structure includes a crossbar, which is installed in a cross shape on the outside of the first fixing structure. A support block is sleeved on the outside of the crossbar, and the support block is installed on the outside of the first fixing structure.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0017] Please see Figure 1-6 This utility model provides a technical solution: A thermal pipeline repair device includes a repair patch 1, a first fixing structure 2, and a second fixing structure 3.

[0018] The repair patch 1 is preferably an arc-shaped metal patch that matches the outer diameter of the thermal pipe being repaired. An inner sealing gasket 12 and an expansion gasket 13 are sequentially adhered to the inner surface of the patch. The inner sealing gasket 12 is made of high-temperature resistant rubber or composite sealing material, which can tightly adhere to the outer wall of the pipe to prevent media leakage. The expansion gasket 13 is arranged between the reinforcing plate 11 and the sealing gasket 12, and can expand slightly after being heated or pressurized to compensate for minor unevenness in the pipe wall and improve sealing performance. A reinforcing plate 11 is fixed to the outer surface of the repair patch 1 to enhance the overall rigidity of the patch and prevent secondary damage to the damaged area caused by media pressure.

[0019] Multiple first fixing structures 2 are evenly installed on the outer circumferential surface of the repair patch 1. The first fixing structure 2 is preferably a second clamp 21, which is formed by multiple clamp units enclosing an arc shape. Adjacent clamp units are connected by a second screw 22 and a third nut 23. After installation, the repair patch 1 can be evenly tightened along the circumferential direction to ensure that the device is stably attached to the pipe surface.

[0020] A second fixing structure 3 is provided outside the first fixing structure 2. The second fixing structure 3 includes a crossbar 32, a support block 31, and a first fixing ring 33. The crossbar 32 is arranged in a cross pattern on the outer surface of the first fixing structure 2. The first fixing ring 33 is installed at both ends of the crossbar. A first fixing nut 34 is screwed to one side of the fixing ring 33, which can axially lock the crossbar 32. The support block 31 is sleeved on the outside of the crossbar 32. The support block 31 is connected to the second fixing ring 24 on the repair patch 1, so that a stable support relationship is formed between the crossbar 32 and the repair patch 1, improving the overall compressive strength and limiting performance.

[0021] To facilitate the overall installation and disassembly of the device, a first clamp 35 is also installed on one side of the first fixing ring 33. The connection of the clamp 35 is locked and tightened by the first screw 36 and the second nut 37 to form a circumferential clamp on the pipe and the repair patch 1, which facilitates quick fixation without welding or cutting.

[0022] Installation method: First, clean the surface of the leaking or damaged part of the heating pipe to ensure that the pipe wall is dry and flat; then, attach the repair patch 1 together with the inner sealing gasket 12 and expansion gasket 13 to the damaged area of ​​the outer wall of the pipe; then, sequentially put several first fixing structures 2 on the outside of the repair patch 1 and lock them with the second screw 22 and the third nut 23 to make the repair patch 1 initially fit with the pipe; install the second fixing structure 3, fix the crossbar 32 crosswise on the outside of the first fixing structure 2, put the support block 31 into it and connect it with the second fixing ring 24 on the repair patch 1, and tighten the first fixing nut 34 at the same time to limit the displacement of the crossbar 32; put the first clamp 35 on the outer periphery of the device and lock it with the first screw 36 and the second nut 37 in sequence until the repair patch 1 is evenly pressed against the outer wall of the pipe to form a reliable seal.

[0023] Through the above steps, this device can perform temporary emergency repairs on leaking parts of heating pipelines without interrupting supply or pressure, achieving a comprehensive effect of rapid installation, secure fixing, and reliable sealing, providing a safe transition for subsequent permanent maintenance.
