Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipeline laying, and in particular to a water pipeline laying device. Background Technology
[0002] Water pipeline laying is a key part of water supply system construction, involving the selection of pipeline materials, application of construction technology, and environmental adaptability design.
[0003] In related technologies, reference can be made to Korean Patent No. KR20230082589A, which discloses a laminated pipe segment having a laminated pipe segment length, a laminated pipe segment axis extending along the laminated pipe segment length, an outer diameter and an inner diameter determining the wall thickness, and a laminated pipe segment cross-section formed along the laminated pipe segment axis. This allows for the individual configuration of wear areas in the laminated pipe or its simple application to a segment of a very complex laminated pipe axis as part of the laminated pipe through which workpieces are deposited. The wall thickness is determined at a specific height on the laminated pipe segment axis, and the laminated pipe segment is produced by an additive manufacturing method.
[0004] When the above-mentioned pipe sections are connected to each other, traditional flanges are usually used. However, this traditional flange structure only wraps the outer surface of the pipe. The integrity and sealing of the pipe and flange are not perfect. The flange can easily separate from the pipe, causing the fluid flowing inside the pipe to leak from the gap between the flange and the pipe. This makes the pipe unusable for a long time and requires frequent maintenance or reconstruction. Utility Model Content
[0005] To improve the sealing and stability of connections between pipe sections, this application provides a water pipe network laying device.
[0006] This application provides a water pipeline laying device, which adopts the following technical solution:
[0007] A water pipe network laying device includes a connecting base pipe that abuts against the end of a water pipe. A first connecting mechanism and a second connecting mechanism are respectively provided at both ends of the connecting base pipe. The connecting base pipe is connected to the water pipe via the first connecting mechanism, and connected to a connecting base pipe at the end of an adjacent water pipe via the second connecting mechanism. The first connecting mechanism includes:
[0008] A connecting inner pipe is provided on the connecting base pipe and abuts against the inner wall of the water pipe.
[0009] An outer connecting pipe is provided on a connecting base pipe and abuts against the outer wall of the water pipe. The inner connecting pipe and the outer connecting pipe cooperate to clamp the inner and outer sides of the water pipe.
[0010] A sealing assembly is disposed on the inner connecting pipe and the outer connecting pipe and is used to fill and seal the gap between the inner connecting pipe and the outer connecting pipe and the base connecting pipe.
[0011] By adopting the above technical solution, an inner connecting pipe and an outer connecting pipe are installed on the connecting base pipe. The inner connecting pipe and the outer connecting pipe are in contact with both the inner and outer sides of the water pipe. The gap between the inner connecting pipe and the outer connecting pipe and the connecting base pipe is filled and sealed by a sealing component. This greatly improves the sealing performance of the two water pipes on the inner side of the connection. Furthermore, the connecting base pipe, the inner connecting pipe, and the outer connecting pipe form a whole, which increases the stability and durability of the water pipe connection and extends the service life of the water pipe connection.
[0012] Optionally, the sealing assembly includes:
[0013] A sealing inner ring and a sealing outer ring are respectively disposed at the ends of the connecting inner tube and the connecting outer tube;
[0014] A sealing gasket is provided on the connecting base pipe. When the connecting base pipe is pressed against the water pipe, the sealing gasket deforms and fills the gap between the inner and outer sides of the water pipe and the inner and outer connecting pipes.
[0015] By adopting the above technical solution, sealing inner rings and sealing outer rings are installed on the inner and outer connecting pipes respectively. The sealing inner and outer rings block the gap opening between the inner and outer connecting pipes and the water pipe, thereby reducing the probability of fluid from inside or outside the water pipe entering the gap between the inner and outer connecting pipes and the water pipe. Then, a sealing gasket is installed on the connecting base pipe. When the connecting base pipe is pressed against the water pipe, the sealing gasket deforms and fills the gap between the inner and outer sides of the water pipe and the inner and outer connecting pipes, thereby performing a secondary seal on the gap between the inner and outer connecting pipes and the water pipe, greatly improving the sealing performance between the inner and outer connecting pipes and the water pipe.
[0016] Optionally, the second connecting mechanism includes:
[0017] A connecting male plate is mounted on a connecting base pipe;
[0018] A connecting female plate is disposed on a connecting base pipe adjacent to a connecting base pipe with a connecting male plate. A connecting groove is provided on the connecting female plate, and the connecting male plate is inserted into the connecting groove.
[0019] A limiting component is disposed on two adjacent connecting base tubes and is used to limit the position of the connecting male plate in the connecting groove.
[0020] By adopting the above technical solution, a male connecting plate and a female connecting plate are installed on two adjacent connecting base pipes respectively. The male connecting plate is inserted into the connecting groove on the female connecting plate, and then a limiting component is used to limit the male connecting plate in the connecting groove, thereby completing the connection of two adjacent connecting base pipes.
[0021] Optionally, the limiting component includes:
[0022] The limiting rings are provided in two forms, and the two limiting rings are respectively provided on two adjacent connecting base pipes;
[0023] The limiting screw has limiting holes on both limiting rings, and both ends of the limiting screw pass through the two limiting holes respectively;
[0024] The limiting nuts are provided in two form, and the two limiting nuts are respectively threaded to the two ends of the limiting screw that pass through the limiting hole and abut against the two limiting rings.
[0025] By adopting the above technical solution, limiting rings are installed on the connecting base pipes. After the connecting male plate and connecting female plate on the two connecting base pipes are inserted together, the moving limiting screw passes through the limiting holes on the two limiting rings. Then, the limiting nuts at both ends of the limiting screw are tightened against the two limiting rings, thus completing the fixing of the position of the two limiting rings and firmly limiting the connecting male plate and connecting female plate together.
[0026] Optionally, the middle section of the limiting screw located between the two limiting rings and both ends passing through the limiting hole are covered with rubber protective sleeves.
[0027] By adopting the above technical solution, rubber protective sleeves are fitted on the middle section and both ends of the limiting screw, thereby protecting the threads on the limiting screw and reducing the probability of thread wear after the limiting screw has been affected by the external environment for a long time, which facilitates the subsequent disassembly of the limiting screw.
[0028] Optionally, the end of the connecting inner tube away from the connecting base tube is provided with an inclined first guide surface, and the diameter of the first guide surface near the connecting base tube is smaller than the diameter of the end away from the connecting base tube.
[0029] By adopting the above technical solution, an inclined first guide surface is opened on the connecting inner pipe, so that the fluid in the water pipe can flow into the connecting base pipe along the first guide surface when it flows, which greatly reduces the thrust generated when the fluid comes into contact with the connecting inner pipe and improves the stability of the connecting inner pipe.
[0030] Optionally, the end of the connecting outer tube away from the connecting base tube is provided with an inclined second guide surface, and the diameter of the second guide surface near the connecting base tube is smaller than the diameter of the end away from the connecting base tube.
[0031] By adopting the above technical solution, an inclined second guide surface is opened on the connecting outer pipe. When the connecting outer pipe is moved close to the water pipe, the second guide surface will guide the water pipe, making it easier for the water pipe to be inserted between the connecting outer pipe and the connecting inner pipe, thus improving the installation efficiency.
[0032] In summary, this application includes at least one of the following beneficial technical effects:
[0033] 1. By installing an inner connecting pipe and an outer connecting pipe on the connecting base pipe, the inner and outer connecting pipes make contact with the inner and outer sides of the water pipe. The gap between the inner and outer connecting pipes and the connecting base pipe is filled and sealed by a sealing component, which greatly improves the sealing performance of the two water pipes on the inner side of the connection. The connecting base pipe, inner connecting pipe and outer connecting pipe form a whole, which increases the stability and durability of the water pipe connection and extends the service life of the water pipe connection.
[0034] 2. By installing sealing inner and outer rings on the inner and outer connecting pipes respectively, the sealing inner and outer rings block the gap opening between the inner and outer connecting pipes and the water pipe, thereby reducing the probability of fluid from inside or outside the water pipe entering the gap between the inner and outer connecting pipes and the water pipe. Then, a sealing gasket is installed on the connecting base pipe. When the connecting base pipe and the water pipe are pressed together, the sealing gasket deforms and fills the gap between the inner and outer sides of the water pipe and the inner and outer connecting pipes, thereby performing a secondary seal on the gap between the inner and outer connecting pipes and the water pipe, which greatly improves the sealing performance between the inner and outer connecting pipes and the water pipe.
[0035] 3. By creating an inclined second guide surface on the connecting outer pipe, the second guide surface guides the water pipe when the connecting outer pipe is moved close to the water pipe, making it easier for the water pipe to be inserted between the connecting outer pipe and the connecting inner pipe, thus improving installation efficiency.

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.
[0041] This application discloses a water pipe network laying device.
[0042] Reference Figure 1 The water pipe network laying device includes a connecting base pipe 11, the surface of which abuts against the end of the water pipe, and a first connecting mechanism 2 and a second connecting mechanism 3 respectively provided at both ends of the connecting base pipe 11. The connecting base pipe 11 is connected to the water pipe through the first connecting mechanism 2, and the connecting base pipe 11 is connected to the connecting base pipe 11 at the end of the adjacent water pipe through the second connecting mechanism 3.
[0043] Reference Figure 1 and Figure 2 The first connecting mechanism 2 includes an inner connecting tube 21, an outer connecting tube 22, and a sealing assembly 23. Both the inner connecting tube 21 and the outer connecting tube 22 are fixedly installed on the surface of the connecting base tube 11 that contacts the water pipe. The inner connecting tube 21 and the outer connecting tube 22 are located on the inner and outer sides of the water pipe, respectively. The inner connecting tube 21 contacts the inner wall of the water pipe. The outer connecting tube 22 contacts the outer wall of the water pipe. The sealing assembly 23 is disposed on the inner connecting tube 21 and the outer connecting tube 22 and is used to fill and seal the gaps between the inner connecting tube 21 and the outer connecting tube 22 and the connecting base tube 11.
[0044] Reference Figure 2 and Figure 3 The sealing assembly 23 includes an inner sealing ring 41, an outer sealing ring 42, and a sealing gasket 43. The inner sealing ring 41 and the outer sealing ring 42 are respectively fixedly installed at the ends of the connecting inner tube 21 and the connecting outer tube 22 away from the connecting base tube 11. The inner sealing ring 41 and the outer sealing ring 42 block the gap opening between the connecting inner tube 21 and the connecting outer tube 22 and the water pipe, thereby reducing the probability of fluid from inside or outside the water pipe entering the gap between the connecting inner tube 21 and the connecting outer tube 22 and the water pipe.
[0045] Reference Figure 3The sealing gasket 43 is fixedly placed on one side surface of the connecting base pipe 11 between the connecting inner pipe 21 and the connecting outer pipe 22. When the connecting base pipe 11 is pressed against the water pipe, the sealing gasket 43 deforms and fills the gap between the inner and outer sides of the water pipe and the connecting inner pipe 21 and the connecting outer pipe 22, thereby providing a secondary seal between the connecting inner pipe 21 and the connecting outer pipe 22 and the water pipe, greatly improving the sealing performance between the connecting inner pipe 21 and the connecting outer pipe 22 and the water pipe.
[0046] Reference Figure 3 An inclined first guide surface 24 is provided at the end of the connecting inner tube 21 away from the connecting base tube 11. The diameter of the first guide surface 24 at the end near the connecting base tube 11 is smaller than the diameter at the end away from the connecting base tube 11. The first guide surface 24 allows the fluid in the water pipe to flow into the connecting base tube 11 along the first guide surface 24, greatly reducing the thrust generated when the fluid comes into contact with the connecting inner tube 21 and improving the stability of the connecting inner tube 21.
[0047] Reference Figure 3 An inclined second guide surface 25 is provided at the end of the connecting outer pipe 22 away from the connecting base pipe 11. The diameter of the second guide surface 25 at the end near the connecting base pipe 11 is smaller than the diameter at the end away from the connecting base pipe 11. The second guide surface 25 guides the water pipe when the connecting outer pipe 22 is moved closer to the water pipe, making it easier for the water pipe to be inserted between the connecting outer pipe 22 and the connecting inner pipe 21, thus improving installation efficiency.
[0048] Reference Figure 1 and Figure 2 The second connecting mechanism 3 includes a male connecting plate 31, a female connecting plate 32, and a limiting component 33. The male connecting plate 31 and the female connecting plate 32 are respectively fixedly installed on the side surface of two adjacent connecting base pipes 11 facing away from the water pipe. A connecting groove is provided on the female connecting plate 32, and the male connecting plate 31 is inserted into the connecting groove. The limiting component 33 is provided on the two adjacent connecting base pipes 11 and is used to limit the position of the male connecting plate 31 in the connecting groove.
[0049] Reference Figure 2 The limiting assembly 33 includes a limiting ring 34, a limiting screw 35, and a limiting nut 36. The limiting ring 34 is fixedly installed on the outer wall of the connecting base pipe 11. A limiting hole penetrating the thickness of the limiting ring 34 is provided on the limiting ring 34. The two ends of the limiting screw 35 pass through the limiting holes of the limiting rings 34 on two adjacent connecting base pipes 11. Two limiting nuts 36 are provided, and the two limiting nuts 36 are respectively threaded to the two ends of the limiting screw 35 that pass through the limiting holes and abut against the two limiting rings 34. This completes the fixing of the position of the two limiting rings 34. The middle section of the limiting screw 35 between the two limiting rings 34 and the two ends that pass through the limiting holes are covered with rubber protective sleeves.
[0050] The working principle of this application embodiment is as follows:
[0051] An inner connecting pipe 21 and an outer connecting pipe 22 are installed on the connecting base pipe 11. The inner connecting pipe 21 and the outer connecting pipe 22 are connected to both the inner and outer sides of the water pipe. The gap between the inner connecting pipe 21 and the outer connecting pipe 22 and the connecting base pipe 11 is filled and sealed by the sealing inner ring 41, the sealing outer ring 42 and the sealing gasket 43. This greatly improves the sealing performance of the two water pipes on the inner side of the connection. The connecting base pipe 11, the inner connecting pipe 21 and the outer connecting pipe 22 form a whole, which increases the stability and durability of the water pipe connection and improves the service life of the water pipe connection.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
