An emergency water-stopping component for burst water supply pipe connections

Abstract

This utility model discloses an emergency water-stopping component for burst water supply pipe connections, relating to the technical field of water-stopping components. It includes a water pipe to be treated, with a water-stopping plunger inserted into its inner end and a rubber water-blocking ring installed on the outer end of the plunger. This design allows a horn-shaped water-blocking cylinder to pre-cover the outer wall of the water pipe, forming a protective barrier. This effectively blocks water splashing when the conical inserter with the plunger is inserted, preventing environmental pollution or wetting of personnel. The universal ball block rotates flexibly within the hollow outer frame, reducing frictional resistance between the water-stopping plunger and the connecting cylinder, allowing the outer cylinder to smoothly cover the water pipe. It also limits the water-stopping plunger, preventing it from shifting during advancement and ensuring stable movement. Furthermore, the threaded connection between the threaded extension rod and the water-stopping plunger, along with the outer end bearing, ensures that the outer connecting cylinder does not rotate when the lever is turned, maintaining the stability of the inclined connecting rod, telescopic crossbar, and other structures.

Description

Technical Field

[0001] This utility model relates to the field of water-stopping components, and in particular to an emergency water-stopping component for a burst water supply pipe connection. Background Technology

[0002] During the operation of the water supply network, pipe bursts are prone to occur at the connection points due to problems such as aging pipe materials, pressure fluctuations, and installation deviations. If the water cannot be stopped in time, it will cause a large amount of water waste, and may also flood surrounding facilities, affect residents' domestic water use or industrial production, and even cause secondary risks such as road collapse.

[0003] A plastic water pipe stopper with Chinese patent number CN219692619U includes an anti-slip water-stop block, a first flared metal plate, a first hexagonal extended nut, and a second hexagonal extended nut. A needle is integrally provided at the left end of the anti-slip water-stop block, and a threaded rod is integrally provided at the middle of the right end of the anti-slip water-stop block. Through holes are provided on the side surfaces of both the first and second flared metal plates. This utility model has a reasonable structure and good practicality, allowing for length adjustment according to the actual length of the plastic water pipe on site. This facilitates the installation or removal of the device by workers using an external hexagonal handle or an external extraction tool.

[0004] In the emergency water-stopping process used for burst water supply pipe connections, when the water-stopping component is inserted into the burst pipe, high-pressure water can easily splash, which not only pollutes the operating environment but may also cause operators to slip and fall, increasing safety hazards. Summary of the Invention

[0007] As a further technical solution of this utility model, a T-shaped handle is fixedly connected to the end of the threaded extension rod away from the water pipe to be treated, and an anti-slip sleeve is fixedly connected to the outer end of the T-shaped handle.

[0008] As a further technical solution of this utility model, multiple telescopic crossbars are arranged in a ring at equal intervals, and an external spring is sleeved on the outer end of the telescopic crossbars.

[0010] As a further technical solution of this utility model, the inner end of the circular slot is fixedly connected with multiple hollow outer ring frames, which are arranged in a ring at equal intervals.

[0011] As a further technical solution of this utility model, the inner end of the hollow outer ring frame is rotatably connected to a universal ball block, and the universal ball block and the water-stop plunger are in contact with each other on the outer wall surface of the end of the connecting cylinder.

[0012] As a further technical solution of this utility model, the outer end of the rubber water-blocking ring is fixedly connected with a frosted outer coating, and the frosted outer coating and the inner wall of the water pipe to be treated are tightly bonded to each other.

[0013] As a further technical solution of this utility model, a conical insertion head is fixedly connected to one end of the rubber water-blocking ring near the water pipe to be treated.

[0014] This utility model provides an emergency water-stopping component for burst pipe connections in water supply systems, which has the following advantages compared with the prior art: This design presents an emergency water-stopping component for burst water supply pipe connections. The solution involves a horn-shaped water-blocking cylinder that pre-covers the outer wall of the water pipe to form a protective barrier. This effectively prevents water splashing when the conical plunger with plunger is inserted, avoiding environmental pollution or wetting of personnel. Combined with a universal ball block that rotates flexibly within the hollow outer frame, this reduces frictional resistance between the water-stopping plunger and the connecting cylinder, allowing the outer cylinder to smoothly carry the horn-shaped water-blocking cylinder to cover the water pipe. It also limits the water-stopping plunger, preventing it from shifting during advancement and ensuring stable movement. Furthermore, the threaded connection between the threaded extension rod and the water-stopping plunger, along with the outer end bearing, ensures that the outer connecting cylinder does not rotate when the lever is turned, maintaining the stability of the diagonal connecting rod, telescopic crossbar, and other structural components.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 This utility model provides an emergency water-stopping component for a burst water supply pipe connection: it includes a water pipe to be treated 1, a water-stopping plunger 2 inserted into the inner end of the water pipe to be treated 1, a rubber water-blocking ring 4 installed on the outer end of the water-stopping plunger 2, a threaded extension rod 6 threadedly connected to the end of the water-stopping plunger 2 away from the water pipe to be treated 1, a bearing movably connected to the outer end of the threaded extension rod 6, an external connecting cylinder 8 fixedly connected to the outer end of the bearing, a plurality of oblique connecting rods 9 arranged in a ring at equal intervals fixedly connected to the outer end of the external connecting cylinder 8, a follower outer cylinder 10 fixedly connected to the end of the plurality of oblique connecting rods 9 away from the external connecting cylinder 8, a horn-shaped water-blocking cylinder 11 fixedly connected to the end of the follower outer cylinder 10 away from the hand-held T-shaped rod 7, and a plurality of telescopic crossbars 12 fixedly connected to the end of the external connecting cylinder 8 away from the hand-held T-shaped rod 7.

[0019] Please see Figures 1-3 The threaded extension rod 6 is fixedly connected to a T-shaped handle 7 at the end away from the water pipe 1 to be treated. The outer end of the T-shaped handle 7 is fixedly connected to an anti-slip sleeve 18. Multiple telescopic crossbars 12 are arranged in a ring at equal intervals. An external spring 13 is sleeved on the outer end of the telescopic crossbar 12. An abutment connecting cylinder 14 is fixedly connected to the end of the telescopic crossbar 12 away from the external connecting cylinder 8. A conical insertion head 3 is fixedly connected to the end of the rubber water-blocking ring 4 near the water pipe 1 to be treated.

[0020] By pre-covering the outer wall of the water pipe 1 to be treated with a funnel-shaped water baffle 11 to form a ring-shaped protective barrier, the water splashing generated at the burst point when the conical insertion head 3 with the rubber water-blocking ring 4 and the water-stopping plunger 2 is inserted into the water pipe 1 to be treated can be effectively blocked, thus avoiding the spread of water to pollute the operating environment or wet the operators, and improving the comfort of operation.

[0021] Please see Figures 1-4 The connecting cylinder 14 has a ring-shaped slot 15 at one end near the water-stopping plunger 2. Multiple hollow outer ring frames 16 are fixedly connected to the inner end of the ring-shaped slot 15. The multiple hollow outer ring frames 16 are arranged in a ring at equal intervals. A universal ball block 17 is rotatably connected to the inner end of the hollow outer ring frame 16. The universal ball block 17 and the outer wall surface of the end of the water-stopping plunger 2 near the connecting cylinder 14 are in contact with each other. A frosted outer coating 5 is fixedly connected to the outer end of the rubber water-blocking ring 4. The frosted outer coating 5 and the inner wall of the water pipe 1 to be treated are tightly fitted together.

[0022] During the pushing process, the universal ball block 17 rotates flexibly within the hollow outer ring frame 16 and presses tightly against the outer wall of the water-stop plunger 2 near the connecting cylinder 14. This reduces the frictional resistance between the water-stop plunger 2 and the connecting cylinder 14, making the follower outer cylinder 10 move more smoothly with the outer connecting cylinder 8 via the inclined connecting rod 9. This makes it easier to drive the horn-shaped water baffle 11 to cover the outer wall of the water pipe 1 to be treated, and also limits and stabilizes the water-stop plunger 2, preventing it from deviating during pushing and ensuring the stability of the water-stop plunger 2's movement posture.

[0023] The working principle of this utility model is as follows: When using this solution, first hold the T-shaped handle 7 with the anti-slip sleeve 18 and align the conical insert 3 with the burst point of the water pipe 1 to be treated. When pushing the T-shaped handle 7, the external connecting cylinder 8 drives the follower outer cylinder 10 to move synchronously through multiple annularly spaced inclined connecting rods 9 fixed at its outer end. The follower outer cylinder 10 first drives the horn-shaped water-blocking cylinder 11 away from the end of the T-shaped handle 7 to move closer to the outer wall of the water pipe 1 to be treated. At the same time, multiple annularly spaced telescopic crossbars 12 of the external connecting cylinder 8 away from the end of the T-shaped handle 7 extend with the pushing action. The external springs 13 sleeved on the outer ends of the telescopic crossbars 12 are stretched to generate a rebound force, pushing the telescopic crossbars 12 to move closer to the outer wall of the water pipe 1 to be treated. The connecting cylinder 14 at the end of rod 12 away from the external connecting cylinder 8 moves closer to the water-stopping plunger 2. The connecting cylinder 14, through multiple equidistantly spaced hollow outer ring frames 16 fixed within a ring-shaped slot 15 near the end of the water-stopping plunger 2, drives the universal ball blocks 17 rotatably connected within the hollow outer ring frames 16 to press tightly against the outer wall surface of the end of the water-stopping plunger 2 near the connecting cylinder 14. This pressing action ensures the water-stopping plunger 2 maintains a stable posture during subsequent movements, and the flexible rotation of the universal ball blocks 17 reduces the frictional resistance between the water-stopping plunger 2 and the connecting cylinder 14. This allows the follower outer cylinder 10 to drive the horn-shaped baffle cylinder 11 to cover the outer wall of the water pipe 1 to be treated. The rotation and pushing action are smoother. After the horn-shaped water baffle 11 is installed, it forms a ring-shaped protective barrier. Continue to push the T-shaped rod 7 so that the conical insert head 3, along with the rubber water-blocking ring 4 and the water-stopping plunger 2, is inserted into the water pipe 1 to be treated. At this time, the water splash caused by the plunger insertion at the burst point of the water pipe 1 will be blocked by the horn-shaped water baffle 11, preventing the water splash from spreading outward. At the same time, the frosted outer coating 5 of the rubber water-blocking ring 4 gradually adheres tightly to the inner wall of the water pipe 1 as the conical insert head 3 and the water-stopping plunger 2 are inserted, reducing the amount of water overflowing from the gap between the water-stopping plunger 2 and the inner wall of the water pipe 1 to be treated, further reducing the degree of water splashing. Rotate the T-shaped rod 7 to drive the threaded extension As the long rotating rod 6 rotates, the threaded extension rod 6 is threadedly connected to the water-stopping plunger 2. The rotating threaded extension rod 6 pushes the water-stopping plunger 2 further into the water pipe 1 to be treated. The bearing connected to the outer end of the threaded extension rod 6 prevents the outer connecting cylinder 8 from rotating with the threaded extension rod 6. At this time, the universal ball block 17 continuously presses against the outer wall of the water-stopping plunger 2, ensuring that the water-stopping plunger 2 is steadily pushed forward while always providing a guarantee for the smooth movement of the follow-up outer cylinder 10 and the trumpet-shaped water-blocking cylinder 11. Finally, with the barrier effect of the trumpet-shaped water-blocking cylinder 11 and the sealing effect of the rubber water-blocking ring 4 and the frosted outer coating 5, the problem of water splashing is effectively solved and the emergency water stop is achieved at the connection of the water pipe 1 to be treated.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
