Description

Technical Field

[0001] This utility model relates to the field of urban pipeline maintenance technology, specifically a rapid sealing device for pipelines. Background Technology

[0002] During the long-term operation of urban pipeline networks, factors such as environmental corrosion, media erosion, and pipeline aging can easily lead to malfunctions such as rust leaks, pinhole leaks, and crack leaks. Especially in winter, if a leak occurs in the main pipeline, traditional handling methods require shutting down the gas supply and replacing the pipe, which can cause large-scale and prolonged gas outages in the main urban area, severely impacting residents' lives and business operations.

[0003] Existing sealing devices have significant drawbacks: First, the sealing process is complex and time-consuming, making it difficult to meet emergency sealing needs; second, they lack specificity, failing to achieve a tight seal when the pipeline surface is irregular, easily leading to secondary leaks; third, a thorough cleaning of the pipeline surface anti-corrosion layer is required before sealing, further extending the sealing operation time; and fourth, their applicability is limited, only suitable for sealing straight pipe sections, unable to adapt to irregularly shaped fittings such as tees and elbows, and unable to cope with diverse leakage scenarios in pipeline networks, thus failing to meet current needs. Therefore, we propose a rapid sealing device for pipeline networks. Utility Model Content

[0004] The purpose of this utility model is to provide a rapid sealing device for pipeline networks, so as to solve the problems mentioned in the background art, such as the complexity of operation, poor adaptability, long sealing time, and inability to adapt to irregular pipe fittings of existing sealing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid sealing device for pipeline networks, comprising a first pressure plate, which is arranged horizontally, and two second pressure plates arranged longitudinally on both sides of the upper surface of the first pressure plate, wherein the first pressure plate and the second pressure plate are welded and fixed, a sealing plate is provided at the middle position below the first pressure plate, and the sealing plate has an arc-shaped structure, wherein a filling mechanism is provided at the bottom of the sealing plate, the filling mechanism is used to seal the gaps on the pipeline, and three equidistant adjusting bolts are provided at the middle position above the first pressure plate, the adjusting bolts are threadedly connected to the first pressure plate, and the position of the sealing plate is adjusted by adjusting the adjusting bolts. Semi-circular clamps are provided on both sides below the first pressure plate, and the two clamps are spliced ​​together and fitted to the outer wall of the pipeline to be repaired, wherein the two ends of the clamps are respectively connected to the second pressure plate.

[0006] Preferably, locking bolts are provided on the outer sides of both ends of the clamp, and the sidewalls of the lower ends of the locking bolts are welded and fixed to the clamp. The front and rear ends of the second pressure plate are provided with clamp mounting holes, and the two ends of the locking bolts pass through the clamp mounting holes respectively. Nuts matching the locking bolts are provided above the clamp mounting holes.

[0007] Preferably, the upper surface of the sealing plate is provided with three universal joints aligned with the position of the adjusting bolt. Each universal joint includes a fixed end and a movable end, and the fixed end and the movable end are universally fitted together. The bottom of the fixed end is fixed to the sealing plate, and the upper end of the movable end is connected to the bottom of the adjusting bolt.

[0008] Preferably, the filling mechanism includes a silicone plate and a sealing adhesive disposed at the bottom of the silicone plate.

[0009] Preferably, the first pressure plate, the second pressure plate, and the clamp are all made of stainless steel.

[0010] The shape of the sealing plate is adapted to the outer diameter of the pipe to be repaired.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model addresses the leakage problem of various pipe fittings such as straight pipes, tees, and elbows in urban pipeline networks. This device, through a customized pressure plate precisely matched to the pipe fitting type and a sealing plate matching the pipeline's outer diameter, breaks through the limitation of existing devices that can only seal straight pipes, achieving full-scenario coverage. Simultaneously, the device eliminates the need for comprehensive cleaning of the pipeline's anti-corrosion layer; only the leak location needs to be cleaned, significantly simplifying the sealing process, effectively shortening emergency sealing time, and enabling rapid response to pipeline leak emergency needs, reducing the impact of power outages on residents' lives and commercial operations.

[0013] 2. To ensure a tight seal, this utility model includes a silicone plate and sealing adhesive sequentially arranged on the lower surface of the sealing plate. The silicone plate has good elasticity and can closely fit irregular parts of the pipeline surface, filling in minor protrusions or depressions. The sealing adhesive can deeply fill the gaps in the leaking area, forming a double seal. In addition, the universal joint connection structure between the adjusting bolt and the sealing plate allows for flexible adjustment of the sealing plate angle, ensuring that it always fits tightly against the pipeline surface. This fundamentally eliminates the risk of secondary leakage after sealing and ensures the long-term stable operation of the urban pipeline network.

[0014] 3. The core components of this utility model are all common, conventional mechanical parts found in the market, making them easy to manufacture and obtain. The raw materials are readily available, and the overall cost is controllable, effectively reducing pipeline maintenance investment. Furthermore, the operation process is simple, requiring no specialized technicians to quickly learn, facilitating its widespread application in urban pipeline maintenance teams at all levels. In addition, by strengthening the structural strength of the semi-circular clamps, pressure plates, and adjusting bolts, the device's applicability can be easily expanded to high-pressure pipeline sealing scenarios in long-distance pipelines.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-7 This utility model provides an embodiment of a pipeline quick sealing device, including a first pressure plate 1, which is arranged horizontally. The upper surface of the first pressure plate 1 is provided with two longitudinally arranged second pressure plates 2, and the first pressure plate 1 and the second pressure plates 2 are welded and fixed. A sealing plate 3 is provided at the middle position below the first pressure plate 1, and the sealing plate 3 has an arc-shaped structure. The bottom of the sealing plate 3 is provided with a filling mechanism 9, which is used to seal the gaps on the pipeline. Three equidistant adjusting bolts 4 are provided at the middle position above the first pressure plate 1. The adjusting bolts 4 are threadedly connected to the first pressure plate 1, and the position of the sealing plate 3 is adjusted by adjusting the adjusting bolts 4. Semi-circular clamps 5 are provided on both sides below the first pressure plate 1. After the two clamps 5 are spliced ​​together, they fit and wrap around the outer wall of the pipeline to be repaired. The two ends of the clamps 5 are respectively connected to the second pressure plate 2.

[0025] By splicing two semi-circular clamps 5 to wrap around the pipe to be repaired, the overall device position is fixed by the connection between the clamps 5 and the second pressure plate 2. Then, by turning the adjusting bolts 4 on the first pressure plate 1, the sealing plate 3 is pushed down, so that the bottom filling mechanism 9 fits against the pipe leak to achieve a seal. The welded structure of the horizontal first pressure plate and the vertical second pressure plate improves the overall stability. The three adjusting bolts can apply pressure evenly to ensure that the sealing plate is under balanced force. The arc-shaped sealing plate can better adapt to the pipe shape and improve the sealing fit.

[0026] Please refer to the figure. Locking bolts 6 are provided on the outer sides of both ends of the clamp 5, and the lower sidewalls of the locking bolts 6 are welded and fixed to the clamp 5. The front and rear ends of the second pressure plate 2 have clamp mounting holes, and both ends of the locking bolts 6 pass through these holes. Nuts 7, matching the locking bolts 6, are provided above the clamp mounting holes. The clamp 5 passes through the mounting holes of the second pressure plate 2 via the locking bolts 6 welded at both ends, and is then tightened by the nuts 7, ensuring that the two semi-circular clamps 5 tightly encircle the pipe, firmly fixing the entire device to the pipe. The locking bolt and nut mating structure allows for quick tightening and loosening of the clamps, facilitating rapid installation of the device while ensuring the device's fixation strength on the pipe, preventing displacement due to pressure during the sealing process.

[0027] Please see Figure 2 and Figure 3 The upper surface of the sealing plate 3 is provided with three universal connectors 10 aligned with the positions of the adjusting bolts 4. Each universal connector 10 includes a fixed end and a movable end, which are universally fitted together. The bottom of the fixed end is fixed to the sealing plate 3, and the upper end of the movable end is connected to the bottom of the adjusting bolt 4. The adjusting bolt 4 is connected to the sealing plate 3 through the universal connectors 10. When the adjusting bolt 4 is turned, the movable end can flexibly adjust its angle as the bolt rotates, while the fixed end drives the sealing plate 3 to maintain a close fit with the pipe surface, achieving multi-angle adaptive clamping. The universal connection structure can compensate for unevenness of the pipe surface or minor deviations in the installation of the device, ensuring that the sealing plate is always in close contact with the pipe surface and avoiding sealing problems caused by angular deviations.

[0028] Please see Figure 4 The filling mechanism 9 includes a silicone plate and a sealing adhesive placed at the bottom of the silicone plate. The silicone plate conforms to irregular parts of the pipe surface through its elastic deformation, while the sealing adhesive fills the gaps at the leak points. Under the pressure of the adjusting bolt, the two together form a double sealing layer, blocking the flow of leaking media. The combination of the elasticity of the silicone plate and the fluidity of the sealing adhesive can adapt to the slight unevenness of the pipe surface and deeply fill the leak gaps, greatly improving the sealing reliability and effectively preventing secondary leaks.

[0029] Furthermore, the first pressure plate 1, the second pressure plate 2, and the clamp 5 are all made of stainless steel. Stainless steel has high strength and corrosion resistance, and can withstand the pressure of the adjusting bolt and the reaction force of the medium in the pipeline during pipeline sealing operations, while resisting the corrosion of the external environment and the pipeline medium.

[0030] Furthermore, the shape of the sealing plate 3 is adapted to the outer diameter of the pipe to be repaired, and the arc curvature of the sealing plate 3 is consistent with the outer diameter of the pipe to be repaired. Under pressure, it can form a large area of ​​contact with the pipe surface, so that the sealing effect of the filling mechanism 9 is evenly distributed in the leakage area. The adapted shape design increases the contact area between the sealing plate and the pipe, making the sealing pressure distribution more uniform, avoiding sealing failure caused by insufficient local pressure, and improving the adaptability to pipes of different diameters.

[0031] Working principle: When using, first, splice the two semi-circular clamps 5 and wrap them around the outer wall of the pipe to be repaired, so that the locking bolts 6 at both ends of the clamps 5 pass through the clamp mounting holes of the second pressure plate 2, tighten the nuts 7 and fix it initially. Then, align the silicone plate and sealing glue at the bottom of the sealing plate 3 with the pipe leak. By turning the adjusting bolts 4 on the first pressure plate 1, the angle self-adaptive function of the universal connector 10 is used to push the sealing plate 4 down, so that the silicone plate and sealing glue are tightly attached to the pipe surface. Then, gradually tighten the nuts 7 on the clamps 5 to fix the position of the whole device. Finally, continue to turn the adjusting bolts 4 until the filling mechanism completely seals the pipe gap, and the sealing operation is completed.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
