Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to an anchored waterproof sealing device for water conservancy engineering construction. Background Technology

[0002] In fields such as construction, water conservancy, and underground engineering, the waterproof sealing of anchored structures is a crucial aspect of ensuring project safety. An anchored waterproof sealing device, as a core component connecting the anchoring assembly to the substrate, must simultaneously meet the dual requirements of anchor stability and waterproof sealing. Its performance directly affects the project's impermeability and durability. Especially in complex geological formations, high water pressure, or vibration environments, the device's waterproof sealing effect is vital to preventing leakage-induced structural instability and is key to improving the overall reliability of the project.

[0003] In existing technologies, waterproof sealing of anchoring structures is mostly achieved by using a single rubber ring and bolt tightening. The technical principle is that the elastic deformation of the rubber ring fills the connection gap, and the preload of the bolts maintains the sealing pressure. Some structures add a metal cap to enhance the fixing effect. This type of structure relies on the tight fit between the rubber ring and the contact surface to block the water penetration path through physical barriers, and is widely used in various waterproofing scenarios for anchoring nodes.

[0004] However, existing sealing structures are prone to loosening due to long-term vibration, water pressure fluctuations, or slight settlement of the substrate. The fit between the rubber ring and the connecting groove is susceptible to gaps due to reduced preload, leading to seal failure. Furthermore, traditional fixed structures are time-consuming to install and prone to overall sealing performance degradation due to bolt loosening, making them unsuitable for long-term stable waterproofing in complex environments and posing potential risks to project safety. Therefore, an anchored waterproof sealing device is proposed to address these issues. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides an anchored waterproof sealing device, which aims to improve the existing problem of time-consuming and easily loosened fixing between components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anchored waterproof sealing device includes an anchor base and a sleeve. A connecting ring 1 is fixedly connected to the top of the anchor base, and a connecting ring 2 is fixedly connected to the bottom of the sleeve. Sealing components are provided inside the connecting ring 1 and the connecting ring 2. Multiple connecting components are provided inside the connecting ring 2, and the connecting components are distributed in a circumferential manner. Each connecting component includes a locking post. The upper part of the outer wall of the locking post is fixedly connected to the inside of the connecting ring 2, and the lower part of the outer wall of the locking post is slidably connected to the inside of the connecting ring 1. A movable post is slidably connected inside the locking post. A rotating handle is fixedly connected to the top of the outer wall of the movable post, and the rotating handle is located above the locking post. A limit groove is formed at the bottom of the outer wall of the movable post, and multiple limit balls are provided at the bottom of the outer wall of the movable post. The multiple limit balls are distributed in a circumferential manner inside the lower part of the locking post, and the outer walls of the multiple limit balls are slidably connected to the inside of the locking post. A limit component is provided at the top of the inside of the locking post.

[0008] Preferably, the aforementioned limiting component includes a linkage column, which is fixedly connected to the upper part of the outer wall of the movable column. Multiple limiting plates are fixedly connected to the outer wall of the linkage column, and the limiting plates are distributed in a circumferential shape. A limiting ring is provided on the outer wall of the linkage column, and the outer wall of the limiting ring is fixedly connected to the upper part of the inner wall of the locking column.

[0009] Preferably, a limit spring is provided below the linkage column, with one end of the limit spring fixedly connected to the bottom of the linkage column and the other end of the limit spring slidably connected to the inner wall of the locking column.

[0010] Preferably, the casing has an inner tube inside, the bottom of which is fixedly connected to the top of the connecting ring 2. Multiple connecting strips are fixedly connected between the casing and the side wall of the inner tube, and the multiple connecting strips are distributed in a circumferential manner. Multiple grouting holes are opened on the outer wall of the casing, and the multiple grouting holes are distributed in a circumferential array.

[0011] Preferably, the sealing assembly includes a sealing ring, a receiving groove is provided at the top of the connecting ring, the bottom of the sealing ring is fixedly connected to the bottom of the inner wall of the receiving groove, and a plurality of positioning grooves are provided on the outer wall of the sealing ring, the plurality of positioning grooves being distributed in a circumferential shape.

[0012] Preferably, the bottom of the connecting ring two is provided with a fitting groove, and the outer wall of the sealing ring is slidably connected to the inner wall of the fitting groove.

[0013] Preferably, a plurality of retaining balls are provided on one side of the aforementioned fitting groove. The plurality of retaining balls are distributed in a circumferential shape inside the second connecting ring. Each retaining ball has a connecting plate fixedly connected to its sidewall. The outer wall of the connecting plate is slidably connected to the inside of the second connecting ring.

[0014] Preferably, a reset spring is provided on the side of the connecting plate. One end of the reset spring is fixedly connected to the inside of the second connecting ring, and the other end of the reset spring is slidably connected to the side wall of the connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the operator rotates and presses down the top handle, causing the handle to move downwards and drive the movable column, allowing the limiting ball in the limiting groove to slide out and engage with the hole. Simultaneously, the linkage column, carrying the limiting plate, passes through the limiting ring, compressing the limiting spring. The rotation of the handle causes the limiting plate to engage under the limiting ring, fixing the limiting ball in the engaged state. This achieves the effect of quickly fixing the anchor seat and the sleeve, solving the problem of time-consuming and loosening fixation between components, and improving installation efficiency and connection stability. Connecting ring one is aligned with connecting ring two, causing the sealing ring inside the former to engage with the latter's fitting groove. After the sealing ring is fully engaged, the return spring pushes the connecting plate back to its original position, causing the retaining ball to engage with the sealing ring positioning groove, completing the limiting effect and preventing the sealing ring from loosening due to vibration or water pressure. This solves the problem of traditional sealing rings easily falling off, improving installation sealing and structural stability. Attached Figure Description

[0026] 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.

[0027] Reference Figures 1-5 This utility model discloses an anchored waterproof sealing device, which includes an anchor seat 1 and a sleeve 3. The anchor seat 1 is made of Q355B steel and is used to support the entire device and provide stable support. The top of the anchor seat 1 is fixedly connected by welding to a connecting ring 2, which is cut from a No. 20 seamless steel pipe and has an inner diameter that matches that of the connecting ring 7. This is used to mate with the connecting ring 7 of the sleeve 3 to achieve docking. The sleeve 3 is made of Q235B steel pipe with an anti-corrosion coating on the outer wall. The bottom is fixedly connected by welding to a connecting ring 7, which is made of the same material as the connecting ring 2. The sealing components inside the connecting ring 2 and the connecting ring 7 are used to fill the gap between the two rings and prevent water leakage.

[0028] Multiple circumferentially distributed connecting components inside connecting ring 2 7 are used to rigidly fix connecting ring 1 2 and connecting ring 2 7. The locking post 8 of the connecting component is made of stainless steel. Its upper outer wall is fixedly connected to the inside of connecting ring 2 7 by welding. Its lower outer wall forms a clearance fit with the through hole inside connecting ring 1 2, and is slidably connected to the inside of connecting ring 1 2 to transmit locking force. The movable post 10, made of 45# steel, is slidably connected inside the locking post 8 and is used to control the extension and retraction of the limit ball 9. The top of the outer wall of the movable post 10 is fixedly connected to the rotating handle 12 by key. The handle 12 is made of ABS engineering plastic injection molding and has anti-slip texture on the surface. Above the locking post 8, the movable post 10 is easily operated by the staff. The bottom of the outer wall of the movable post 10 has a limiting groove 11 milled by milling, with an arc-shaped cross-section, to accommodate the limiting balls 9 and control their pop-out and retraction. Multiple limiting balls 9 at the bottom of the outer wall of the movable post 10 are made of bearing steel and are distributed in a circumferential shape in the through hole at the bottom inside the locking post 8. The outer wall and the inner wall of the locking post 8 form a sliding fit to engage with the slot of the through hole of the connecting ring 2 to achieve locking. The limiting component at the top inside the locking post 8 is used to lock the position of the movable post 10. The linkage post 13 of the limiting component is made of 304 stainless steel and is fixed internally by interference fit. Connected to the upper part of the outer wall of the movable column 10, it drives the limiting plate 14 to move synchronously. Multiple circumferentially distributed limiting plates 14, also made of stainless steel, are welded to the outer wall of the linkage column 13 and used to cooperate with the limiting ring 15 to achieve axial positioning of the movable column 10. The limiting ring 15 on the outer wall of the linkage column 13 is stamped from Q235B steel plate and its outer wall is welded to the upper part of the inner wall of the locking column 8. The limiting ring 15 has holes with the same cross-section as the linkage column 13 and the limiting plate 14 inside, used to prevent the limiting plate 14 from falling back and maintain the locked state. The limiting spring 16 below the linkage column 13 is made of spring steel. One end is welded to the bottom of the linkage column 13, and the other end abuts against the spring seat on the inner wall of the locking column 8, which is used to provide an upward reset force for the movable column 10. The inner tube 4 inside the sleeve 3 is made of the same material as the sleeve 3 and is used to run cables or pipes. The bottom is fixedly connected to the top of the connecting ring 7 by welding. Multiple circumferentially distributed connecting strips 5, made of Q235B flat steel, are fixedly connected between the side walls of the sleeve 3 and the inner tube 4 by welding to enhance the connection strength between the sleeve 3 and the inner tube 4 and prevent deformation. Multiple circumferentially arrayed grouting holes 6 are opened on the outer wall of the sleeve 3 to inject waterproof grouting material to fill the gaps and enhance the sealing performance.

[0029] Reference Figure 6 and Figure 7The sealing ring 18 of the sealing assembly is made of EPDM rubber. Its bottom is fixed to the bottom of the receiving groove 17 via a vulcanization process, filling the gap between connecting ring 12 and connecting ring 27 to prevent liquid leakage. The receiving groove 17, milled at the top of connecting ring 12, is used to receive the sealing ring 18. Multiple circumferentially distributed positioning grooves 19, with arc-shaped cross-sections, are formed on the outer wall of the sealing ring 18 via a molding process, used to cooperate with the retaining ball 23 to achieve axial positioning of the sealing ring 18. The fitting groove 20, milled at the bottom of connecting ring 27, has an inner diameter matching the outer diameter of the sealing ring 18, used for fitting... The sealing ring 18 provides a sealing space. Multiple circumferentially distributed retaining balls 23, made of bearing steel, are located on one side of the fitting groove 20 and are used to lock the sealing ring 18 by engaging with the positioning groove 19. The sidewalls of the multiple retaining balls 23 are fixedly connected by welding to the connecting plate 22, made of 304 stainless steel. The outer wall of the connecting plate 22 forms a sliding fit with the sliding groove inside the connecting ring 27, which is used to synchronously drive the retaining balls 23 to move. The return spring 21, made of spring steel, is set on the side of the connecting plate 22. One end is welded to the spring seat inside the connecting ring 27, and the other end abuts against the sidewall of the connecting plate 22, which is used to provide return elasticity for the retaining balls 23.

[0030] The working principle of this utility model is as follows: When installing the anchored waterproof sealing device, the worker first aligns the connecting ring 12 at the top of the anchor seat 1 with the connecting ring 27 at the bottom of the sleeve 3, so that the sealing ring 18 on the inner wall of the receiving groove 17 at the top of the connecting ring 12 is inserted into the fitting groove 20 at the bottom of the connecting ring 27. At this time, the outer wall of the sealing ring 18 will squeeze the retaining ball 23 on one side of the inner wall of the fitting groove 20, so that the retaining ball 23 drives the connecting plate 22 to retract into the inner wall of the connecting ring 27, and the return spring 21 is compressed. When the sealing ring 18 is completely inserted into the fitting groove 20, the return spring 21 pushes the connecting plate 22 back to reset, and then the retaining ball 23 is inserted into the positioning groove 19 on the side wall of the sealing ring 18, thus completing the limiting of the sealing ring 18 and achieving the effect of preventing the sealing ring 18 from loosening.

[0031] Subsequently, the staff inserted the locking pin 8 inside the second connecting ring 7 into the corresponding hole of the first connecting ring 2. Then, they rotated and pressed down the handle 12 on the top of the locking pin 8. First, the handle 12 moved downward, causing the movable pin 10 to move as well. This caused multiple limiting balls 9 inside the limiting groove 11 to slide out and get into the corresponding hole of the first connecting ring 2. At the same time, the linkage pin 13 caused the limiting plate 14 to pass through the limiting ring 15, and the limiting spring 16 to be compressed. The rotation of the handle 12 caused the linkage pin 13 and the limiting plate 14 to rotate, thereby locking the limiting plate 14 below the limiting ring 15, thus completing the limiting of the limiting balls 9, so that they are always in the state of being locked in the hole of the first connecting ring 2. This achieves the effect of quickly fixing the anchor seat 1 and the sleeve 3.
