[0001] This utility model relates to the field of pipeline repair technology, and in particular to a pipeline leak sealing and repair device. Background Technology
[0002] During the operation of air conditioning equipment, water supply and drainage pipes or containers may leak in certain areas. Because the water pressure at the leak point is relatively high, it is necessary to drain some of the water from the leak point during repair to reduce the water pressure to a level suitable for welding.
[0003] Current pipe repair methods involve shutting off the water supply for repairs or waiting for the water at the leak to drain naturally, followed by welding to seal the leak once the water pressure at the leak point has decreased to a level suitable for welding. However, shutting off the water supply for repairs disrupts the normal operation of equipment, and some equipment cannot be repaired without water. Waiting for the water to drain naturally can be time-consuming, resulting in low pipe repair efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] It should be noted that in the description of this utility model, the terms "connection" and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] This utility model embodiment provides a pipe leak sealing and repair device, referring to... Figure 1 and Figure 2The device includes a plug 1, a pressure relief pipe 2, a water supply pipe 3, and a water pump 4. The plug 1 is attached to the pipe 100 to be repaired and is arranged around the leakage point of the pipe 100. One end of the pressure relief pipe 2 is connected to the plug 1, and the water pump 4 is installed on the pressure relief pipe 2. One end of the water supply pipe 3 is connected to the pressure relief pipe 2 and is located between the plug 1 and the water pump 4. The other end of the water supply pipe 3 is connected to a water source.
[0031] The working principle of the above device is as follows:
[0032] First, based on the location, shape, and size of the leak point in pipe 100, a corresponding plug 1 is made;
[0033] Next, attach the prepared plug 1 to the leak point of pipe 100, and connect one end of the pressure relief pipe 2 to the plug 1;
[0034] Then, turn on water pump 4 to transfer the water discharged from the leak point to quickly reduce the pressure at the leak point; if the water volume at the leak point is insufficient to support the operation of water pump 4, then add tap water to the pressure relief pipe 2 through water supply pipe 3 to support the operation of water pump 4.
[0035] Once the water pressure at the leak point has decreased to a level suitable for welding, weld plug 1 onto pipe 100. After welding, remove pressure relief pipe 2 from plug 1, and then install a valve or screw plug on plug 1. This completes the repair work.
[0036] As described above, the pipe leak sealing and repair device provided in this application can repair the pipe 100 while the equipment is running, and the water pump 4 can transfer the discharged water at the leak point, which can quickly reduce the pressure at the leak point and improve the repair efficiency of the pipe 100.
[0037] Based on the above structure, a first valve 21 is installed on the pressure relief pipe 2;
[0038] And / or, a second valve 31 is provided on the water supply pipe 3.
[0039] The first valve 21 and the second valve 31 are used to control the opening and closing of the pressure relief pipe 2 and the water supply pipe 3, respectively, so that the working status of the device can be flexibly controlled.
[0040] Furthermore, the pressure relief pipe 2 includes a flexible hose section and a rigid pipe section. The flexible hose section is connected between the plug 1 and one end of the rigid pipe section, and the water pump 4 is installed on the rigid pipe section. Because the pressure relief pipe 2 adopts a structure in which the flexible hose section and the rigid pipe section are connected, the position of the water pump 4 is not restricted by the pipe 100, thus making the device more convenient to use.
[0041] Based on the above structure, the pipe leak sealing and repair device also includes a pipe connector 8 and a pressure gauge 9. The pipe connector 8 is connected between the plug 1 and one end of the hose section, and the pressure gauge 9 is installed on the pipe connector 8. The pressure gauge 9 is used to detect and display the water pressure at the outlet of the plug 1, so that workers can determine whether the water pressure at the leak point has dropped to a range suitable for welding.
[0042] Furthermore, to improve the sealing between the plug 1 and the pipe 100, a sealing gasket 10 is provided between the plug 1 and the pipe 100. The outer contour of the sealing gasket 10 should be slightly smaller than the outer contour of the plug 1 to avoid the sealing gasket 10 affecting the welding of the plug 1.
[0043] In some embodiments, the sealing gasket 10 can be glued to the periphery of the leak point to prevent the sealing gasket 10 from moving or becoming misaligned during maintenance.
[0044] Reference Figure 3 and Figure 4 In some embodiments, the pipe sealing and repair device further includes a water tank 6, a pressure relief pipe 2 connected between the plug 1 and the inlet of the water tank 6, and a water supply pipe 3 connected between the pressure relief pipe 2 and the outlet of the water tank 6.
[0045] The water tank 6 serves two purposes: firstly, it can recycle water discharged from the leak point, avoiding waste of water resources; secondly, it can prevent the distance between the tap water interface and the leak point from being too far, which could lead to difficulties in connecting the water supply pipe 3 or even prevent it from being connected at all.
[0046] It should be noted that, in Figure 4 In the diagram, only the rigid pipe section of the pressure relief pipe is shown; the flexible pipe section is not shown. The flexible pipe section can be made of commercially available flexible water pipes, and its structure will not be described in detail here.
[0047] Based on the above structure, an inlet is provided at the top of water tank 6, and an outlet is provided at the bottom of water tank 6. This design can prevent the water from failing to drain properly due to a low water level in water tank 6.
[0048] Furthermore, the pipe sealing and repair device also includes a trolley 7, with a water pump 4 and a water tank 6 mounted on the trolley 7.
[0049] Specifically, the trolley 7 includes a frame, multiple wheels mounted at the bottom of the frame, and handles fixed to the frame. The water pump 4 and water tank 6 are mounted on the frame. In use, the operator can move the device by pulling the handles.
[0050] Figure 4 In the embodiment shown, the frame is provided with a plurality of fixing blocks for the periphery of the water tank 6, which can restrict the position of the water tank 6 relative to the frame.
[0051] Specifically, the fixing block is bolted to the frame and is L-shaped overall, with one corner of the water tank 6 able to be secured to the fixing block. In some embodiments, there are two fixing blocks, each located at one of the two opposite corners of the water tank 6. In other embodiments, there are four fixing blocks, each located at one of the four corners of the water tank 6.
[0052] Reference Figure 5 The pipe leak sealing and repair device also includes a clamp 5 for fixing the plug 1 to the pipe 100. Specifically, the clamp 5 includes a first arc-shaped plate 51, a second arc-shaped plate 52, and a fastener 53 for connecting the first arc-shaped plate 51 and the second arc-shaped plate 52. The first arc-shaped plate 51 and the second arc-shaped plate 52 can form an annular ring, and the plug 1 is clamped between the annular ring and the pipe 100. The clamp 5 can fix the plug 1 to the pipe 100 during the repair process, so as to facilitate pressure relief at the leak point and welding of the plug 1 to the pipe 100.
[0053] Figure 5 In the illustrated embodiment, the first curved plate 51 and the second arc-shaped plate 52 have the same shape, and the annular ring formed by them is adapted to the shape of the pipe 100 to be repaired; the fastener 53 can be a bolt, and the two side edges of the first curved plate 51 and the second arc-shaped plate 52 are connected by multiple bolts respectively. In this embodiment, the clamping force between the first curved plate 51 and the second arc-shaped plate 52 presses the plug 1 tightly onto the pipe 100 to facilitate subsequent maintenance.
[0054] Based on the above structure, the first arc plate 51 is provided with a clearance hole 511, through which part of the plug 1 is exposed.
[0055] Figure 5 In the illustrated embodiment, the plug 1 includes a plate and an annular connector welded to the plate. The plate has a through hole corresponding to the inner hole of the annular connector, and the annular connector has an external or internal thread for connecting to the pressure relief pipe 2. A first curved plate 51 is pressed onto the plate, and the annular connector and part of the edge of the plate are exposed through the clearance hole 511.
[0056] In the above structure, since the edge of part of the plate is exposed through the clearance hole 511, the plate can be spot welded to the pipe 100 through the clearance hole 511 before the clamp 5 is removed; after the plug 1 and the pipe 100 are initially welded and positioned, the clamp 5 is removed, and then the periphery of the plate is welded to firmly weld the plug 1 to the pipe 100.
[0057] Based on the above structure, the curvature of the plate is adapted to the shape of the pipe 100 to be repaired so that the two can fit together more tightly.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
