Description

Technical Field

[0001] The utility model relates to the technical field related to online in-situ repair of urban water supply, in particular to an in-situ online repair device for urban water supply pipelines without water outage. Background Art

[0002] With rapid urban development and the incomplete extension of water supply networks, water pipeline leakage and water resource management are attracting increasing attention. Failure to promptly identify and repair leaks can lead to severe water waste and secondary disasters such as road collapse. Traditional pipeline repair techniques require water outages, work stoppages, and production halts, resulting in high repair costs and significant inconvenience for residents. Previous pipeline repair equipment was prone to industrial accidents due to excessive water pressure within the pipes, as well as secondary bursts caused by the rapid increase in dynamic pressure when the male and female pipes are closed. Furthermore, traditional ring-shaped sealing arcs have a small sealing surface and are prone to splitting in two, which can lead to secondary leaks.

[0003] However, traditional pipe leak repair equipment often uses cast iron repair parts, which are not only difficult to operate but are generally only suitable for small pipe diameters. In daily production, due to the varying lengths and sizes of leaks and damage in water supply pipes, conventional pipe repair tools have poor versatility, often leading to product mismatches in inventory and an inability to quickly repair pipes. This delays repairs and places a high pressure on the repair tool inventory of pipeline maintenance units, causing significant inconvenience in repair work. Therefore, to address these issues, a device for in-situ, non-stop repair of urban water supply pipes has been proposed. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art and solve the problem of water supply network leakage, the utility model proposes an in-situ online repair device for urban water supply pipelines without water outage.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows: the utility model is an in-situ online repair device for urban water supply pipelines without water outage, comprising a rubber plate, a lining plate and a support plate, wherein the lining plate is located between the rubber plate and the support plate, and the lining plate is slidably connected to the rubber plate and the support plate;

[0006] The outer surface of the support plate is provided with an opening, and the opening of the outer surface of the support plate is fixedly connected to the connecting plate 1 and the connecting plate 2, and the front surface of the connecting plate 1 is fixedly connected to a plurality of evenly distributed guide plates;

[0007] A limiting component is provided between every two opposing guide plates, and a connecting component is provided between the limiting component and the second connecting plate.

[0008] Preferably, the second connecting plate is configured to be L-shaped, and the right side of the first connecting plate is in contact with the left side of the second connecting plate.

[0009] Preferably, the limiting assembly includes a sliding groove provided on one side opposite to the two guide plates, a sliding plate is slidably connected between the two sliding grooves, and a through-type threaded hole is provided at the inner center of the sliding plate.

[0010] Preferably, the connecting assembly includes a bolt threadedly connected to the inside of the threaded hole, the right end of the bolt passes through the connecting plate 2, a flat washer passes through the right side of the outer surface of the bolt, a nut threadedly connected to the right side of the outer surface of the bolt, and the flat washer is arranged between the nut and the connecting plate 2.

[0011] Preferably, the interior of the rubber plate is arranged in a grid shape.

[0012] Preferably, both left and right sides of the opening on the outer surface of the rubber plate are configured as inclined surfaces.

[0013] Preferably, protective sleeves are provided on both the left and right sides of the outer surface of the bolt.

[0014] The utility model is beneficial in that:

[0015] 1. The utility model does not need to shut down the water supply valve when in use, and the equipment will not affect the water supply to residents during maintenance, so the leaking pipe network can be repaired quickly, thereby shortening the repair process and improving work efficiency.

[0016] 2. The utility model adopts a unique overlapping grid structure. For pipelines with longer and larger leaks, multiple repair devices can be used in series to overlap, thereby solving the problem that other devices cannot quickly repair pipelines due to size mismatch, delaying emergency repair time and causing great inconvenience to the repair work. At the same time, the device uses an internal grid design to reduce the pressure of the leaking medium layer by layer, avoiding the secondary pipe burst caused by the rapid increase of pipeline dynamic pressure when the male and female devices are closed.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1-4 As shown, an in-situ online repair device for urban water supply pipelines without water outage includes a rubber plate 1, a lining plate 2 and a support plate 3. The lining plate 2 is located between the rubber plate 1 and the support plate 3. The lining plate 2 is slidably connected to the rubber plate 1 and the support plate 3.

[0027] The outer surface of the support plate 3 is provided with an opening, and a connecting plate 1 31 and a connecting plate 2 32 are fixedly connected to the opening of the outer surface of the support plate 3. A plurality of evenly distributed guide plates 4 are fixedly connected to the front surface of the connecting plate 1 31;

[0028] When working, the position of the damaged and leaking pipe should be determined first, and a working pit should be excavated at a suitable position. After the working pit is excavated, the repair equipment should be pre-fixed and installed at a position adjacent to the damaged pipe. The pre-fixed installation includes adjusting the position of the repair equipment first, and making the rubber plate 1 sleeve on the outer surface of the pipe, and making the support plate 3 sleeve on the outside of the rubber plate 1. The lining plate 2 is for facilitating the installation of the support plate 3. A gap should be left between the support plate 3 and the rubber plate 1. The lining plate 2 effectively fills the gap between the support plate 3 so that the support plate 3 and the lining plate 2 form a whole, further protecting the rubber plate 1. Then the three sets of connecting assemblies and the limiting assemblies are installed in sequence, but the connecting assemblies should not be tightened, and the equipment should only be pre-fixed. Then the repair equipment should be slowly moved to the damaged and leaking position of the pipe, adjusted and installed, and finally the connecting assembly should be tightened.

[0029] The second connecting plate 32 is configured to be L-shaped, and the right side of the connecting plate 1 31 is in contact with the left side of the connecting plate 2 32; during operation, the connecting plate 1 31 can be attached to and separated from the connecting plate 2 32, and the connection and operation between the limiting assembly and the connecting assembly are facilitated by the connecting plate 1 31 and the connecting plate 2 32, thereby facilitating the support plate 3 to fasten the rubber plate 1 and the pipeline.

[0030] The limiting assembly includes a slide groove 9 opened on the opposite side of the two guide plates 4, and a sliding plate 10 is slidably connected between the two slide grooves 9. A through-type threaded hole 11 is opened at the center of the sliding plate 10; when working, the rotation of the bolt 7 is limited by the sliding plate 10, and when not in use, the sliding plate 10 can be moved so that the bolt 7 is stored in the position between the two guide plates 4.

[0031] The connecting assembly includes a bolt 7 threadedly connected to the inside of the threaded hole 11, the right end of the bolt 7 passes through the connecting plate 2 32, a flat washer 5 passes through the right side of the outer surface of the bolt 7, and a nut 6 is threadedly connected to the right side of the outer surface of the bolt 7, and the flat washer 5 is arranged between the nut 6 and the connecting plate 2 32; during operation, the connection between the support plate 3, the connecting plate 1 31 and the connecting plate 2 32 is tightened by threading the nut 6 with the bolt 7 passing through the connecting plate 2 32, and the rubber plate 1 is used to repair the leaking pipe. At the same time, a torque wrench is used to ensure that the correct torque is applied to avoid excessive or insufficient tightening, and each bolt 7 is tightened step by step and evenly in sequence to ensure uniform distribution of tightening force, avoid deformation or stress concentration of the connector, and finally until the leakage phenomenon no longer occurs, that is, the pipeline repair is completed.

[0032] The interior of the rubber sheet 1 is arranged in a grid shape; when working, the rubber sheet 1 adopts a grid structure design, which can effectively reduce the impact of high water pressure in the pipeline, effectively avoid work-related accidents that are easily caused by high water pressure, and the situation where the dynamic pressure rises rapidly when the male and female pipes are closed, causing secondary pipe bursts in the pipeline. It can also effectively avoid the problem of traditional ring-type sealing arcs with small sealing surfaces and easy to split into two halves and prone to secondary leakage. At the same time, it can effectively deal with the problem of damaged pipelines being out of round and poorly fitting with surface impurities, resulting in failure to seal.

[0033] The left and right sides of the opening of the outer surface of the rubber plate 1 are both set to be inclined; when working, so that the two sets of the equipment can fully contact when overlapped, forming an integral style and avoiding leakage.

[0034] Example 2

[0035] See also Figure 5 As shown, compared with Example 1, as another implementation of the present invention, the outer surface of the bolt 7 is provided with a sheath 8 on both sides; when working, the sheath 8 can reduce the loosening of the bolt 7 during vibration or movement and fill the gap between the threads, providing additional sealing protection to prevent liquid leakage.
