Description

TECHNICAL FIELD

[0001] The utility model relates to water conservancy pipeline technical field, specifically, relate to a kind of water conservancy pipeline of disassembling. BACKGROUND

[0002] In the field of water conservancy projects, pipeline system plays a vital role, responsible for the transportation and allocation of water resources. Traditional water conservancy pipeline connection methods mostly use welding, flange connection and other fixed connection forms.

[0003] Although welding connection method can provide relatively firm connection, it faces many problems during pipeline maintenance or replacement. Once a part of the pipeline is damaged, professional welding equipment and technicians are often needed to cut and remove the damaged part, and then repair or replace the new pipe section. This process not only consumes time and effort, but also easily causes thermal effects on the surrounding structure during cutting and welding, leading to changes in the material properties of the pipeline and affecting the overall structural strength and stability. For example, in a large urban water supply network, if a section of the main water supply pipeline connected by welding leaks, local water supply may need to be stopped during maintenance. Long-term maintenance operations will bring great inconvenience to urban residents' life and industrial production, and the economic loss is incalculable.

[0004] Flange connection method is relatively easy to disassemble compared to welding connection, but it also has obvious defects. The use of flange and connecting bolts increases the material cost, installation space and weight of the pipeline system. Moreover, due to factors such as water flow impact, temperature changes and geological movements, the bolts at the flange connection may loosen over time, leading to water leakage. This requires regular inspection and maintenance of the flange connection parts, increasing the operation and maintenance cost and workload. Taking the complex water conservancy pipeline system in an industrial plant as an example, numerous flange connection points need frequent inspection. If a problem occurs at a flange connection point and is not discovered and addressed in time, it may result in damage to production equipment, production interruption and other serious consequences.

[0005] With the continuous development of water conservancy projects, higher requirements are placed on the installation convenience, maintenance efficiency, cost controllability and operation reliability of pipeline systems. Traditional pipeline connection methods have difficulty meeting these needs, so developing a new type of disassembling water conservancy pipeline has become an urgent problem in the field of water conservancy engineering technology. This disassembling water conservancy pipeline should have characteristics such as reasonable structure, excellent sealing performance, simple installation and disassembly operation, low cost and adaptability to various complex working conditions, in order to overcome the shortcomings of traditional pipeline connection methods, improve the overall performance and service life of the water conservancy pipeline system, and ensure the stable operation of water conservancy projects and the effective transportation of water resources.

[0043] In order to make the drawing simple, only the parts related to the present application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0044] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0046] As Figures 1-5 As shown in the figure, the present application provides a detachable water pipeline, which comprises: a pipe body 1 having two ends, one end being a front end 11 and the other end being a rear end 12, the front end 11 of the pipe body 1 being used for connecting with the rear end 12 of the adjacent other pipe body 1; a plug-in pipe 2 is slidingly arranged in the pipe body 1, the plug-in pipe 2 is located near the front end 11, and after sliding, one end of the plug-in pipe 2 extends or retracts from the front end 11, which is a plug-in end 21, the plug-in end 21 is used for being inserted into the rear end 12 of the adjacent other pipe body 1.

[0047] In this embodiment, the pipe body 1 serves as the main conveying channel for water flow, and its clear front end 11 and rear end 12 design, as well as the sliding arrangement of the splicing pipe 2 inside the pipe body 1 near the front end 11, are the basis for realizing the detachable function of the pipeline. In the scenarios of water conservancy construction or pipeline maintenance, when it is necessary to overhaul, replace or expand a certain section of the pipeline, this structure allows direct operation on the target pipe body 1, without the need for large-scale removal of surrounding pipelines or complex cutting operations as in traditional fixed connection pipelines. For example, in the local reconstruction project of urban water supply network, if the pipeline in a certain area is aging or damaged, the detachable design enables workers to quickly locate the problem pipe body 1, pull out the splicing pipe 2 from the rear end of the adjacent pipe body, and then replace the new pipe body 1 or repair the original pipe body before reconnection, greatly shortening the maintenance time, reducing the impact on the continuity of urban water supply, improving the ability of the entire water conservancy pipeline system to respond to unexpected situations and overall operational efficiency, while also reducing the human, material and potential damage to the surrounding environment. costs and risks brought by large-scale construction.

[0048] Further, the inner wall of the pipe body 1 has a first annular sealing surface 13 and a second annular sealing surface 14, the first annular sealing surface 13 is near the front end 11, and the second annular sealing surface 14 is near the rear end 12; the outer wall of the splicing pipe 2 has a first annular abutting surface 23 and a second annular abutting surface 22, the second annular abutting surface 22 is near the splicing end 21 of the splicing pipe 2, and the first annular abutting surface 23 is near the other end of the splicing pipe 2; the first annular abutting surface 23 is used for abutting with the first annular sealing surface 13, and the second annular abutting surface 22 is used for abutting with the second annular sealing surface 14 of the adjacent another pipe body 1.

[0049] In this embodiment, by arranging annular sealing surfaces and abutting surfaces on the inner wall of the pipe body 1 and the outer wall of the splicing pipe 2 respectively, a nested sealing and connecting structure is formed. When the splicing end 21 of the splicing pipe 2 is inserted into the rear end of the adjacent pipe body, the abutting of the first annular abutting surface 23 with the first annular sealing surface 13 and the abutting of the second annular abutting surface 22 with the second annular sealing surface 14 of the adjacent pipe body seal and position the connection from multiple directions. When water flows through the pipeline, this multi-surface abutting structure can effectively prevent water from seeping out of the connection, ensuring the sealing of the water conservancy pipeline.

[0050] Further, the first annular sealing surface 13, the second annular sealing surface 14, the first annular abutting surface 23 and the second annular abutting surface 22 are all conical surfaces.

[0051] In this embodiment, the design of the annular surfaces as conical surfaces brings multiple advantages. First, the conical surfaces have good guiding properties during the pipe connection process. When the spigot pipe 2 is inserted into the rear end of the adjacent pipe body, the conical surfaces can automatically guide the spigot pipe 2 to accurately enter the predetermined position, reducing the adjustment difficulty and time during the connection process. Second, the self-tightening sealing property of the conical surfaces is one of their important advantages. As the water pressure in the pipe increases, the water pressure will generate an outward pushing force on the spigot pipe, and the design of the conical surfaces allows this pushing force to be converted into a pressing force between the abutting surfaces, thereby automatically enhancing the sealing effect. This self-adaptive sealing mechanism does not require additional sealing adjustment devices and can effectively maintain the sealing of the pipe under different water pressure conditions. Whether in a water supply system of a high-rise building in the city facing high water pressure or in a small rural water conservancy facility in a low water pressure environment, the conical surface structure can reliably work, reducing the risk of sealing failure due to changes in water pressure and improving the applicability and stability of the pipe system under various working conditions.

[0052] Further, the first annular sealing surface 13, the second annular sealing surface 14, the first annular abutting surface 23, and the second annular abutting surface 22 each have an elastic sealing gasket.

[0053] In this embodiment, the provision of elastic sealing gaskets on the annular surfaces further enhances the sealing performance of the pipe. The elastic sealing gaskets are made of materials with good elasticity and water resistance, such as rubber or special high-molecular elastomers. During pipe connection, the sealing gaskets are compressed between the abutting surfaces and the sealing surfaces, which can fill the small gaps that may occur due to limitations in processing precision or after long-term use. Moreover, even when the pipe is subjected to a certain degree of external impact or vibration, the sealing gaskets can play a dual role of buffering and sealing, protecting the integrity of the pipe connection. This additional sealing safeguard measure greatly prolongs the service life of the pipe, reduces the cost of equipment damage, downtime maintenance, and other costs caused by leakage, and also reduces the waste of water resources and the risk of pollution to the surrounding environment.

[0054] Further, the spigot pipe 2 is slidingly and rotatably arranged in the pipe body 1, and after the spigot pipe 2 slides and rotates, the first annular abutting surface 23 abuts against the first annular sealing surface 13, and the second annular abutting surface 22 abuts against the second annular sealing surface 14 of the adjacent another pipe body 1.

[0055] In this embodiment, the spigot pipe 2 is first slid to make the first annular abutting surface 23 close to the first annular sealing surface 13 and the second annular abutting surface 22 close to the second annular sealing surface 14 of the another pipe body 1, and then the spigot pipe 2 is rotated and slid on the guide surface to make the first annular abutting surface 23 tightly abut against the first annular sealing surface 13 and the second annular abutting surface 22 tightly abut against the second annular sealing surface 14 of the another pipe body 1, thereby achieving good sealing performance and firmness.

[0056] Further, the pipe body 1 has a first slot 15 and a second slot 16 near the front end 11 and the rear end 12 respectively; the pipe body 1 also has a slot 17 along the circumference of the pipe body 1, one end of the slot 17 communicates with the second slot 16; the outer wall of the insertion pipe 2 has a sliding block 24 which is used to slide in the first slot 15, the second slot 16 and the slot 17; after the sliding block 24 slides in the slot 17, the insertion pipe 2 rotates, and the first annular abutting surface 23 tightly abuts against the first annular sealing surface 13, and the second annular abutting surface 22 tightly abuts against the second annular sealing surface 14 of the adjacent pipe body 1.

[0057] In this embodiment, the first slot 15, the second slot 16 and the slot 17 on the pipe body 1 and the sliding block 24 on the outer wall of the insertion pipe 2 constitute a complete connection and locking mechanism.

[0058] In the initial stage of pipeline installation, the front end 11 of one pipe body 1 is aligned with the rear end 12 of another pipe body 1, so that the first slot 15 communicates with the second slot 16, and the sliding block 24 can slide in the first slot 15 and the second slot 16, thereby facilitating the extension and retraction of the insertion pipe 2 and the insertion of the insertion end 21 of the insertion pipe 2 into the rear end of the adjacent pipe body.

[0059] When the insertion pipe 2 reaches the predetermined position, the sliding block 24 enters the slot 17 and slides along the slot 17, at this time, the insertion pipe 2 rotates under the constraint of the slot 17, so that the first annular abutting surface 23 tightly abuts against the first annular sealing surface 13, and the second annular abutting surface 22 tightly abuts against the second annular sealing surface 14 of the adjacent pipe body, thereby completing the sealing and connecting process.

[0060] Finally, the sliding block 24 is clamped at a specific position (such as the clamping groove 18) in the slot 17, thereby firmly locking the insertion pipe 2 in the connected state. This structure design standardizes and normalizes the pipeline connection process, and the construction personnel only need to move the sliding block 24 according to the specific operation process to complete the complex pipeline connection and locking work.

[0061] Further, the sliding block 24 has a insertion hole 25.

[0062] In this embodiment, the insertion hole 25 provided on the sliding block 24 provides a convenient operation point for pipeline disassembly. When it is necessary to disassemble and maintain or replace the pipeline, the operator can easily apply force to the sliding block 24 by inserting a handle insertion rod 26 into the insertion hole 25. Under the leverage of the handle insertion rod 26, the operator can overcome the friction between the sliding block 24 and the slot or the slot with a small force, so that the sliding block 24 reversely slides in the slot, thereby realizing the disassembly of the pipeline. This not only improves the efficiency of pipeline disassembly, but also reduces the requirements for construction environment and operator skills, so that the pipeline maintenance work is more flexible and efficient, and the influence time on the residents' water use is reduced.

[0063] Further, the strip-shaped locking hole 17 has a clamping groove 18, and the sliding block 24 is clamped in the clamping groove 18 after sliding in the strip-shaped locking hole 17.

[0064] In the embodiment, the clamping groove 18 in the strip-shaped locking hole 17 further enhances the stability of the sliding block 24 in the locking position. After the sliding block is clamped in the clamping groove 18, the edges of the clamping groove 18 mechanically limit the sliding block 24, so that it is difficult to be separated from the locking position when subjected to external forces such as water flow impact and external vibration.

[0065] Further, the front end 11 and the rear end 12 are provided with buffer pads.

[0066] In the embodiment, the buffer pads provided on the front end 11 and the rear end 12 play an important role in the process of pipeline connection and operation. During the connection process, when the plug-in pipe is inserted into the rear end of the adjacent pipe body or the adjacent pipe bodies are butted against each other, the buffer pads can absorb the impact force generated by the collision, preventing the end of the pipe body from being scratched, deformed or damaged due to direct collision.

[0067] During the operation of the pipeline, the buffer pads can also absorb the vibration and noise generated by the water flow impact. In addition, the buffer pads can also relieve the pipeline expansion stress caused by temperature changes to a certain extent, protect the integrity of the pipeline connection part, and further prolong the service life of the pipeline.

[0068] Further, a handle plug rod 26 is arranged in the insertion hole 25 for disassembly.

[0069] In the embodiment, the handle plug rod 26 arranged in the insertion hole 25 for disassembly clearly defines the specific operation mode and tool cooperation relationship of the pipeline disassembly. As a simple and effective disassembly tool, the handle plug rod 26 is closely matched with the insertion hole 25, so that the operator can quickly implement the operation when disassembling the pipeline.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
