Description

Technical Field

[0001] This utility model belongs to the field of pipeline leak prevention technology and relates to a leak repair device. Background Technology

[0002] Water supply pipelines are important facilities in cities, affecting the daily water use of citizens and the normal operation of industrial production. They play an important role in people's daily lives, but in actual use, water supply pipelines inevitably leak due to various reasons.

[0003] When a water supply pipe leaks, the traditional method is to stop the water supply, use equipment to disconnect the pipe, seal the pipe joints with asbestos cement, and then perform maintenance. However, this method requires a long water outage, is labor-intensive and time-consuming, and is inconvenient to operate.

[0004] To address this, Chinese patent application (application number: 200320101192.2) discloses a leak repair device for water supply pipe sockets, comprising an upper semi-circular plate and a lower semi-circular plate. Closed upper and lower sealing ring grooves are respectively formed at the edges of the upper and lower semi-circular plates, and upper and lower sealing rings are respectively embedded therein. Bolt fixing holes are provided at the axial edges of both the upper and lower semi-circular plates for fastening bolts. A drain hole with a sealing plug is provided at the center of either the upper or lower semi-circular plate.

[0005] However, the above method has the following drawbacks: 1. During use, the upper and lower semi-circular buckles need to be fastened to the leaking part of the socket, the fastening bolts need to be tightened, and then the sealing plug needs to be inserted into the drain hole and tightened, making the installation operation relatively troublesome. 2. During installation, personnel need to face the drain hole to see its location, but at this time, the buckles will block the personnel's view, making it impossible for them to see the location on the pipe where water needs to be drained, i.e., the leaking part, thus making it difficult to achieve quick and accurate alignment. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a leak-proof repair device. The technical problem this invention aims to solve is: how to make the repair device installed quickly and accurately.

[0007] The purpose of this utility model can be achieved through the following technical solution: a leak-proof repair device, comprising two semi-shells, each semi-shell comprising a semi-cylindrical sealing part and lugs located on both sides of the sealing part, the two lugs being fastened together, characterized in that a positioning groove and a sealing ring located outside the positioning groove are provided at the center of the inner sidewall of one of the sealing parts, and a protrusion is provided on the outer sidewall of the sealing part opposite to the sealing ring, the cross-section of the positioning groove being circular.

[0008] In practice, first align the protrusion with the leaking part of the pipe. At this point, the corresponding sealing ring should also be aligned with the leaking part. Then, bring the two half-shells closer together until the inner walls of the two sealing parts abut against the pipe. At this point, the two lugs will also abut. Finally, secure the two lugs together to complete the installation. The protrusion extends beyond the outer wall of the sealing part, allowing personnel to simultaneously see the leaking part and the protrusion's position from the side. The alignment of the protrusion with the leaking part and the sealing ring with the leaking part facilitates quick and accurate alignment. After alignment, bring the two half-shells closer together until the inner walls of the two sealing parts abut against the pipe. At this point, the two lugs will abut. Finally, secure the two lugs together to complete the installation. The sealing ring adheres to the inner wall of the sealing part to achieve a seal, eliminating the need for any additional parts and making installation convenient. The positioning groove has a circular cross-section, while the sealing ring is annular. The positioning groove is located at the center of the inner wall of the sealing part. Due to the axially symmetric geometry of the circle, when installing the sealing ring, aligning the center of the sealing ring with the center of the positioning groove and fitting it onto the outer circumference of the positioning groove allows for quick and accurate positioning, which facilitates installation.

[0009] In the aforementioned leak repair device, the protrusion is disc-shaped. The disc shape and geometric symmetry of the protrusion allow personnel to quickly determine the position of its central axis from top, side, and oblique views, enabling rapid and accurate alignment of the protrusion with the leaking part of the pipe.

[0010] In the aforementioned leak repair device, the diameter of the sealing ring is larger than the diameter of the protrusion. Since the sealing ring's diameter is larger than the protrusion's diameter, as long as the protrusion is aligned with the leaking part of the pipe, the leaking part will inevitably be within the sealing ring's effective range. This facilitates easy installation of the repair device while achieving quick and accurate alignment.

[0011] In the aforementioned leak-proof repair device, the diameter of the protrusion is larger than the diameter of the positioning groove. The size of the positioning groove is controlled within a reasonable range to avoid creating excessively large grooves on the inner wall of the sealing part, which would affect structural strength and thus the sealing effect.

[0012] The aforementioned leak-proof repair device has several elongated reinforcing ribs on the outer wall of the sealing part. These reinforcing ribs effectively improve structural strength, thereby ensuring a good seal.

[0013] The aforementioned leak-proof repair device has several protrusions along the length of the outer edge of the lug, and several fixing holes corresponding to the protrusions on the lug for fasteners to pass through. When installing fasteners, personnel do not need to specifically look at the position of the fixing holes from the front; they can roughly determine the position of the fixing holes by feeling the protrusions, which facilitates convenient installation.

[0014] Compared with existing technologies, this leak repair device has the following advantages:

[0015] 1. In this leak repair device, the protrusion protrudes from the outer wall of the sealing part, allowing personnel to see both the location of the pipe leak and the position of the protrusion from the side. When the protrusion is aligned with the location of the pipe leak, the sealing ring is also aligned with the location of the pipe leak, which facilitates quick and accurate alignment.

[0016] 2. In this leak-proof repair device, after alignment, bring the two half-shells close to each other until the inner walls of the two sealing parts abut against the pipe. At this time, the two lugs abut against each other. Finally, fix the two lugs together to complete the installation. At this time, the sealing ring fits against the inner wall of the sealing part to achieve a seal, without the need for any additional parts, making the installation convenient.

[0017] 3. In this leak-proof repair device, the cross-section of the positioning groove is circular, and the sealing ring is annular. The positioning groove is located at the center of the inner wall of the sealing part. Due to the axially symmetric geometric characteristics of the circle, when installing the sealing ring, align the center of the sealing ring with the center of the positioning groove and fit it on the outer circumference of the positioning groove to quickly and accurately complete the positioning, which facilitates installation.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As can be seen, this leak-proof repair device includes two semi-shells 1. Each semi-shell 1 includes a semi-cylindrical sealing part 1a and lugs 1b located on both sides of the sealing part 1a. When the two lugs 1b are fixed together, the two sealing parts 1a form a cylindrical sealing cavity. A positioning groove 4 and a sealing ring 3 located outside the positioning groove 4 are provided at the center of the inner wall of one of the sealing parts 1a. A disc-shaped protrusion 5 is provided on the outer wall of the sealing part 1a opposite the sealing ring 3. Several elongated reinforcing ribs 6 are provided on the outer wall of the sealing part 1a. The reinforcing ribs 6 effectively improve the structural strength, thereby ensuring the sealing effect.

[0027] Specifically, the positioning groove 4 has a circular cross-section, the diameter of the sealing ring 3 is larger than the diameter of the protrusion 5, and the diameter of the protrusion 5 is larger than the diameter of the positioning groove 4. Since the diameter of the sealing ring 3 is larger than the diameter of the protrusion 5, as long as the protrusion 5 is aligned with the leaking part of the pipe, the leaking part will inevitably be within the effective range of the sealing ring 3. This facilitates easy installation of the repair tool while achieving quick and accurate alignment. Similarly, the larger diameter of the sealing ring 3 compared to the protrusion 5 ensures that the leaking part of the pipe will be within the effective range of the sealing ring 3, further facilitating easy installation of the repair tool while achieving quick and accurate alignment.

[0028] The positioning groove 4 has a circular cross-section. The axially symmetric geometry of the circle not only distributes stress evenly in the circumference, avoiding stress concentration at sharp corners, but also evenly absorbs deformation caused by temperature in all directions. In addition, when installing the sealing ring 3, aligning the center of the sealing ring 3 with the center of the positioning groove 4 allows for quick and accurate positioning, which facilitates installation.

[0029] The lug 1b has several protrusions 1b1 along its length at its outer edge, and several fixing holes 7 corresponding to the protrusions 1b1 on the lug 1b for fasteners to pass through. When installing fasteners, personnel do not need to specifically look at the position of the fixing holes 7 from the front; they can roughly determine the position of the fixing holes 7 by touching the protrusions 1b1, which facilitates convenient installation.

[0030] In practical work, first align the protrusion 5 with the leaking part of the pipe. At this time, the sealing ring 3 corresponding to the protrusion 5 should also be aligned with the leaking part of the pipe. Then, bring the two half-shells 1 closer together until the inner walls of the two sealing parts 1a abut against the pipe. At this time, the two lugs 1b abut against each other. The position of the fixing hole 7 can be quickly determined by the protrusion 1b1. When the fastener is passed through the fixing hole 7, the two lugs 1b are fixed together, completing the installation. Specifically, the fastener can be a fastening screw or bolt.

[0031] The protrusion 5 protrudes from the outer wall of the sealing part 1a, allowing personnel to simultaneously see the location of the pipe leak and the position of the protrusion 5 from the side. When the protrusion 5 is aligned with the leaking part of the pipe, the sealing ring 3 is also aligned with the leaking part, facilitating quick and accurate alignment. After alignment, bring the two half-shells 1 closer together until the inner walls of the two sealing parts 1a abut against the pipe. At this point, the two lugs 1b abut against each other. Finally, fix the two lugs 1b together to complete the installation. At this point, the sealing ring 3 adheres to the inner wall of the sealing part 1a to achieve a seal, without the need for any additional parts, making installation convenient. When installing the sealing ring 3, aligning the center of the sealing ring 3 with the center of the positioning groove 4 allows for quick and accurate positioning, further facilitating installation.

[0032] The protrusion 5 protrudes from the outer wall of the sealing part 1a, allowing personnel to simultaneously see the location of the pipe leak and the position of the protrusion 5 from the side. When the protrusion 5 is aligned with the leaking part of the pipe, the sealing ring 3 is also aligned with the leaking part, facilitating quick and accurate alignment. After alignment, bring the two half-shells 1 closer together until the inner walls of the two sealing parts 1a abut against the pipe. At this point, the two lugs 1b abut against each other. Finally, fix the two lugs 1b together to complete the installation. At this point, the sealing ring 3 fits against the inner wall of the sealing part 1a to achieve a seal, without the need for any additional parts, making installation convenient. The positioning groove 4 has a circular cross-section, while the sealing ring 3 is annular. The positioning groove 4 is located at the center of the inner wall of the sealing part 1a. Due to the axially symmetric geometry of the circle, when installing the sealing ring 3, aligning the center of the sealing ring 3 with the center of the positioning groove and fitting it onto the outer circumference of the positioning groove 4 allows for quick and accurate positioning, further facilitating installation.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0034] Although this document frequently uses terms such as half-shell 1, sealing part 1a, lug 1b, protrusion 1b1, sealing ring 3, positioning groove 4, protrusion 5, reinforcing rib 6, and fixing hole 7, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
