Description

Technical Field

[0001] The utility model relates to the technical field of temporary protection devices for pipelines, in particular to a temporary sealing device for a large-diameter pipe opening. Background Art

[0002] During the construction of large-scale projects, due to the large number of pipes required, on-site storage is inevitable to ensure construction progress. However, these pipes are generally stored outdoors nearby. Due to rain and snow, the interior of the pipes will be washed by rainwater and a large amount of water will accumulate, causing severe rust near the pipe openings. Before installation, the pipes must be cleaned and the rust near the pipe openings must be re-polished. At the same time, since most construction sites are carried out in the wild or in villages, there is a risk of animals entering the pipes to keep warm after welding. Due to the long pipelines, these animals are generally difficult to detect, which may cause subsequent pipeline blockage during trial operation, resulting in serious losses.

[0003] Therefore, it is urgent to design a device that can seal and protect the pipe opening when the pipe is stored. Summary of the Invention

[0022] The technical solution of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 to 4 As shown, an embodiment of the present application provides a temporary sealing device for a large-diameter pipe orifice, comprising a sealing fabric 1 for covering the pipe orifice 100, a rotating rod 2, and a plurality of rotating seats 20 arranged and rotated in sequence on the rotating rod 2. Sleeves 3 extending in opposite directions are respectively provided on the circumference of the rotating seats 20, and a pressing member 4 is movably provided on the sleeve 3. The pressing member 4 can move outward relative to the sleeve 3 to press the circumference of the sealing fabric 1 against the inner wall of the pipe orifice 100.

[0024] When in use, the sealing fabric 1 is covered on the orifice of the pipe 100, and then each pressing piece 4 is moved and adjusted so that each pressing piece 4 presses the sealing fabric 1 around the inner wall of the orifice of the pipe 100, thereby blocking the orifice of the pipe 100 and preventing external debris from entering the pipe. It is practical and convenient.

[0025] Furthermore, the sleeve 3 is provided with a locking structure 5 capable of locking the relative position between the pressing member 4 and the sleeve 3 .

[0026] Specifically, the locking structure 5 includes a locking screw hole 51 opened on the side wall of the sleeve 3, and a locking screw 52 screwed on the locking screw hole 51, and the bottom end of the locking screw 52 presses on the pressing piece 4 to lock the relative position between the pressing piece 4 and the sleeve 3.

[0027] When in use, first loosen the locking screw 52 to separate the bottom end of the pressing piece 4 from the pressing piece 4, so that the pressing piece 4 can move smoothly. After the moving pressing piece 4 presses the sealing fabric 1 around the inner wall of the pipe mouth 100, tighten the locking screw 52 to press the bottom end of the pressing piece 4 on the pressing piece 4 to lock the relative position between the pressing piece 4 and the sleeve 3, completing the locking, which is practical and convenient.

[0028] Furthermore, by setting the locking structure 5, the pressing member 4 can be locked at any position of the sleeve 3, and can be applied to pipes with different diameters, with strong applicability.

[0029] In this embodiment, the locking structure 5 is provided close to the outer end surface of the sleeve 3 .

[0030] Furthermore, the pressing member 4 includes a sliding rod 41 movably sleeved on the sleeve 3 , and a pressing strip 42 provided on the outer end surface of the sliding rod 41 .

[0031] Specifically, the top pressure strip 42 and the slide bar 41 are arranged perpendicular to each other, which can make the contact area between the top pressure strip 42 and the inner wall of the pipeline larger and the top pressure more stable.

[0032] Specifically, the material of the top pressure strip 42 is an elastic material, which can make the top pressure strip 42 fit the inner wall of the pipeline more closely when in contact with the inner wall of the pipeline, thereby achieving a better sealing effect and a tighter sealing.

[0033] Furthermore, the rotating rod 2 includes a rod body 21 , and a plurality of rotating seats 20 are sequentially sleeved on the rod body 21 . Limiting plates 22 are provided at both ends of the rod body 21 to prevent the rotating seats 20 from separating from the rod body 21 .

[0034] Specifically, the number of the rotating seats 20 is 3. By rotating and adjusting the positions of the rotating seats 20 respectively, the multiple pressing members 4 can be directed to different positions, thereby allowing the multiple pressing members 4 to press different positions, thereby achieving a better sealing effect.

[0035] Furthermore, the sealing fabric 1 is made of waterproof material.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
