Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to an anti-settlement drainage pipeline adjustment interface device. Background Technology

[0002] Urban drainage pipeline systems are critical infrastructure for ensuring the normal operation of cities. During pipeline laying, it is usually necessary to connect segmented pipelines into a continuous system using interface devices. These pipelines, especially those buried underground, often face complex geological environments, such as uneven foundation settlement and soil creep.

[0003] To address axial, lateral, or angular displacement of pipelines caused by foundation settlement, existing technologies commonly employ flexible joints with elasticity, such as double-sphere rubber joints. These joints utilize the high elasticity of the rubber material itself to absorb and compensate for pipeline displacement within a certain range, thereby avoiding stress concentration caused by rigid connections and protecting the pipeline structure from damage.

[0004] However, while existing flexible interfaces offer displacement compensation capabilities, they face challenges in terms of connection stability and sealing durability. Traditional flange bolt connections, though providing initial tightening force, are prone to slight loosening under dynamic conditions such as continuous water flow impact within drainage pipes and pressure fluctuations caused by pump start-up and shutdown. This loosening not only gradually reduces the connection's tightening force but, more seriously, disrupts the original compression state of the sealing structure, leading to decreased sealing performance and ultimately creating leaks that compromise the safety of the entire drainage system.

[0005] Existing technologies, when addressing the settlement resistance issues of drainage pipelines, struggle to simultaneously ensure the flexibility of joint displacement compensation, the impact resistance of connections, and the dynamic durability of seals. How to guarantee long-term stability and leak-proof sealing of joint connections while providing sufficient settlement adaptability is a pressing technical challenge in this field.

[0006] Therefore, this utility model proposes an anti-settlement drainage pipe adjustment interface device to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above deficiencies, this utility model provides an anti-settlement drainage pipe adjustment interface device, which aims to improve the existing technology. In the face of dynamic working conditions such as foundation settlement and water flow impact, the anti-settlement drainage pipe adjustment interface device has insufficient connection firmness and sealing durability, and there is a risk of loosening and leakage.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an anti-settlement drainage pipe adjustment interface device, comprising a double-sphere rubber joint, a second connecting pipe; and a connecting component and a sealing component disposed inside the double-sphere rubber joint.

[0009] The connecting assembly includes a tube fixedly connected to the end of the second connecting tube, and a fixing block is provided on the outer wall of the tube; the inner wall of the double-ball rubber joint is provided with a sliding groove along the insertion direction of the tube, and a groove that communicates with the end of the sliding groove and extends circumferentially along the double-ball rubber joint.

[0010] The fixing block on the insertion tube can slide into the groove on the inner wall of the double-sphere rubber joint and rotate in the groove to lock it; the sealing assembly includes a rubber ring, a sliding block and a spring, which are arranged in sequence along the axial direction of the insertion tube. One end of the spring abuts against the inner wall structure of the double-sphere rubber joint, and the other end pushes the rubber ring through the sliding block, so that the rubber ring and the outer wall of the insertion tube form an elastically fitted sealing structure.

[0011] Preferably, the groove wall is further provided with a limiting groove for the fixing block to be inserted.

[0012] Preferably, a rubber protrusion ball is fixed on the side wall of the fixing block; the rubber protrusion ball is used to be squeezed and engaged with the limiting groove when the fixing block rotates to the limiting groove position.

[0013] Preferably, the sealing assembly further includes a telescopic rod that passes through the interior of the spring and provides guidance for the compression of the spring.

[0014] Preferably, the sliding block is slidably disposed on the inner wall of the double-sphere rubber joint.

[0015] Preferably, the anti-settlement drainage pipe adjustment interface device further includes a support ring, which is sleeved on the outer wall of the double-sphere rubber joint.

[0016] Preferably, the anti-settlement drainage pipe adjustment interface device further includes a first connecting pipe, which is connected to the end of the double-sphere rubber joint away from the second connecting pipe.

[0017] Preferably, the double-sphere rubber joint is fixedly connected to the first connecting pipe and the second connecting pipe respectively through a flange structure.

[0018] This utility model has the following beneficial effects: 1. In this utility model, by setting a mechanical locking structure consisting of a tube, a fixing block, a rubber convex ball, and a sliding groove, a groove, and a limiting groove on the inner wall of the double-sphere rubber joint, the problem of existing pipe joints being unsecured and prone to loosening and falling off under water flow impact and pressure fluctuation is solved, achieving the technical effects of fast connection, firm locking, and strong impact resistance.

[0019] 2. In this utility model, by setting a dynamic sealing component consisting of a rubber ring, a sliding block, a telescopic rod and a spring, the continuous elastic force of the spring keeps the rubber ring tightly attached to the insertion tube, which solves the problem that the sealing performance of traditional sealing structures is reduced and prone to leakage due to pipeline displacement or aging. It achieves the technical effect of long-lasting and reliable sealing effect and adaptive compensation for pipeline displacement. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 The present invention provides an embodiment of an anti-settlement drainage pipe adjustment interface device, which aims to solve the problems of insufficient connection reliability and poor sealing durability of existing drainage pipe interfaces when facing uneven foundation settlement.

[0024] The anti-settlement drainage pipe adjustment interface device includes a double-sphere rubber joint 1, a first connecting pipe 3, and a second connecting pipe 4. The two ends of the double-sphere rubber joint 1 are fixedly connected to the first connecting pipe 3 and the second connecting pipe 4 respectively through flange structures. A support ring 2 that provides rigid support is sleeved on the outer wall of the double-sphere rubber joint 1. The double-sphere rubber joint 1 is internally integrated with a connecting component 5 for enhancing connection strength and a sealing component 6 for achieving dynamic sealing.

[0025] Specifically, the connecting assembly 5 includes an insertion tube 501 fixedly connected to the end of the second connecting tube 4. A fixing block 505 is provided on the outer wall of the insertion tube 501. A track structure for inserting and locking the fixing block 505 is provided on the inner wall of the double-ball rubber joint 1. The track structure includes a sliding groove 502 opened along the insertion direction of the insertion tube 501 and a groove 503 communicating with the end of the sliding groove 502. The groove 503 extends circumferentially along the double-ball rubber joint 1. When the insertion tube 501 is inserted, the fixing block 505 slides in along the sliding groove 502 and can rotate with the second connecting tube 4 in the groove 503 after being fully inserted. To achieve final locking, a limiting groove 504 for locking is also provided on the groove wall of the groove 503. A rubber protruding ball 506 is correspondingly fixed on the side wall of the fixing block 505. When the fixing block 505 rotates to the position of the limiting groove 504, the rubber protruding ball 506 is squeezed and fits into the limiting groove 504, thereby forming a firm mechanical lock.

[0026] The sealing assembly 6 is disposed inside the double-sphere rubber joint 1. It includes a rubber ring 601, a sliding block 602, a spring 604, and a telescopic rod 603 that guides the spring 604. The rubber ring 601, the sliding block 602, and the spring 604 are arranged sequentially along the axial direction of the insertion tube 501. The telescopic rod 603 passes through the inside of the spring 604. One end of the spring 604 abuts against the inner wall structure of the double-sphere rubber joint 1, and the other end applies a continuous elastic thrust to the rubber ring 601 through the sliding block 602, which is slidably disposed on the inner wall of the double-sphere rubber joint 1. This ensures that the rubber ring 601 is always elastically fitted with the outer wall of the insertion tube 501, forming a reliable dynamic seal.

[0027] The inner wall of the double-sphere rubber joint 1 is composed of a sliding groove 502 along the insertion direction of the insertion tube 501, a groove 503 extending circumferentially along the end of the sliding groove 502 along the double-sphere rubber joint 1, and a limiting groove 504 formed inside the groove wall of the groove 503. This set of track structures provides precise guidance and limitation for the insertion, rotation and final locking of the insertion tube 501.

[0028] Meanwhile, a fixing block 505 corresponding to the locking track is provided on the outer wall of the insertion tube 501, and an elastic rubber protrusion ball 506 is fixed on the side wall of the fixing block 505. In the assembled state, the fixing block 505 at the end of the insertion tube 501 first slides along the sliding groove 502 inside the double-ball rubber joint 1 until the fixing block 505 enters the groove 503. Then, the second connecting tube 4 is rotated to drive the fixing block 505 to rotate in the groove 503. This rotation process will squeeze the rubber protrusion ball 506. When the fixing block 505 rotates to the corresponding position of the limiting groove 504, the compressed rubber protrusion ball 506 instantly springs in and fits into the limiting groove 504. This mechanical locking structure of sliding, rotating and re-embedding ensures the extremely high reliability of the connection between the double-ball rubber joint 1 and the second connecting tube 4, and effectively resists the risk of loosening caused by water flow impact and pressure fluctuation.

[0029] In a preferred embodiment, to ensure the stability of the spring 604's posture during compression, the sealing assembly 6 also includes a telescopic rod 603, which passes through the interior of the spring 604. The telescopic rod 603 provides precise guidance for the axial compression and rebound of the spring 604, preventing the spring 604 from bending or deflecting, thereby ensuring a stable output of the sealing thrust.

[0030] In order to ensure that the elastic force of the spring 604 can be smoothly and unobstructedly transmitted to the rubber ring 601, the sliding block 602 and the inner wall of the double ball rubber joint 1 are connected in a sliding manner. The outer peripheral surface of the sliding block 602 is precisely fitted with the inner wall surface of the double ball rubber joint 1, which can guide its smooth axial movement and maintain the overall coaxiality of the sealing assembly 6.

[0031] To improve the overall pressure resistance and structural strength of the double-sphere rubber joint 1, the device also includes a support ring 2, which is preferably a metal ring. It is fitted on the outer wall of the double-sphere rubber joint 1 to provide radial rigid support for the flexible rubber sphere part and effectively suppress its expansion and deformation under internal high pressure.

[0032] In order to form a complete pipe connection structure, the device also includes a first connecting pipe 3, which is connected to the end of the double-ball rubber joint 1 away from the second connecting pipe 4. More specifically, flanges are provided at both ends of the double-ball rubber joint 1, the corresponding ends of the first connecting pipe 3 and the second connecting pipe 4, and fixed connections between them are achieved by multiple sets of bolts passing through the through holes on the flanges.

[0033] Working principle: When connecting the pipes, first align the insertion tube 501 at the end of the second connecting pipe 4 with the inlet of the double-sphere rubber joint 1 and insert it. During the insertion process, the fixing block 505 on the outer wall of the insertion tube 501 will slide along the groove 502 opened on the inner wall of the double-sphere rubber joint 1 until the fixing block 505 is completely inserted into the groove 503 at the end of the groove 502. Then, rotate the second connecting pipe 4, and the fixing block 505 will move circumferentially in the groove 503. The rubber convex ball 506 on the side wall of the fixing block 505 is squeezed by the groove wall of the groove 503 when it moves. When the second connecting pipe 4 is rotated to the predetermined angle, the fixing block 505 just reaches the top of the limiting groove 504. The squeezed rubber convex ball 506 then springs in and fits into the limiting groove 504. Through this synergistic effect of sliding in, rotating and then embedding, a fast and firm mechanical locking is achieved, which solves the problem of easy loosening under the impact of water flow in the existing connection method.

[0034] While the aforementioned cannula 501 is inserted, its outer wall continuously compresses the rubber ring 601 of the sealing assembly 6. After being compressed, the rubber ring 601 pushes the sliding block 602 behind it, thereby compressing the spring 604. During this process, the telescopic rod 603 provides guidance for the stable compression of the spring 604. After the connection is locked, the elastic potential energy stored in the compressed spring 604 will continuously apply a stable thrust to the rubber ring 601 through the sliding block 602, ensuring that the rubber ring 601 is always tightly attached to the outer wall of the cannula 501. Even if the pipeline undergoes slight displacement or after long-term use, dynamic compensation can be achieved, solving the problem of easy aging and failure of traditional sealing structures.
