Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water delivery pipes, in particular to a water delivery pipe leakage blocking device. Background Art
[0002] A water pipe refers to the pipe from the water source to the water plant (raw water transmission) or from the water plant to the water distribution network (clean water transmission) when the water plant is far away from the water supply area. During long-term use, the water pipe will wear and age, which will reduce the quality of the water pipe, causing it to rupture due to external collision or internal water pressure, causing the water in the pipe to be lost.
[0003] At present, when the side wall of a water pipe is broken, waterproof glue is often wrapped around the broken part of the pipe, and the waterproof tape gradually blocks the broken gap. However, when the water flow rate is fast, the bonding is often not firm, so that some water seeps out, and the water gradually destroys the adhesion between the waterproof tape and the pipe, causing it to separate from the surface of the pipe, resulting in reduced sealing effect of the waterproof tape. Utility Model Content
[0004] In view of the above background technology, the prior art has the shortcomings and defects that the adhesion is often not firm when the water flow rate is fast, so that some water seeps out, and the water gradually destroys the adhesion between the waterproof tape and the pipe, causing it to detach from the pipe surface, resulting in reduced sealing effect of the waterproof tape.
[0005] The utility model discloses a water pipeline plugging device, which comprises a first shell, a positioning groove is provided inside the first shell, an L-shaped positioning block is arranged inside the positioning groove, a side surface of the positioning block is fixedly connected to a second shell, a locking mechanism is arranged on one side of the positioning block located at the positioning groove, and a sealing mechanism is arranged on the inner wall of the first shell and the inner wall of the second shell.
[0006] Furthermore, the locking mechanism includes a magnetic plate, one side of which is fixedly connected to the inside of the positioning groove, and a locking block is provided on one side of the magnetic plate. The magnetic plate and the side corresponding to the locking block repel each other, so that the fixed magnetic plate pushes the locking block to move, so that the locking block is separated from the positioning block, and the positioning block can move freely laterally inside the positioning groove.
[0007] Furthermore, the outer surface of the locking block is slidably connected to the inner wall of the positioning groove, and a side surface of the locking block is provided with an inclined surface.
[0008] Furthermore, the locking mechanism also includes a stepped groove, and the depth of the stepped groove is the same as the upper and lower heights of the inclined surface of the locking block.
[0009] Furthermore, the sealing mechanism includes a limiting ring, the cross-sectional shape of which is T-shaped, wherein the outer surface of one group of the limiting rings is slidably connected to the inner wall of the first shell, and the outer surface of another group of the limiting rings is slidably connected to the inner wall of the second shell.
[0010] Furthermore, the inner walls of the two groups of restriction rings are fixedly connected with an air intake pipe, and one end of the air intake pipe is fixedly connected with an air bag.
[0011] Furthermore, a sealing strip is fixedly connected to one side surface of the first shell, and an outer surface of the sealing strip is slidably connected to an inner wall of the second shell.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model connects the second shell through one side of the L-shaped positioning block and inserts it into the first shell. A locking mechanism is provided on one side of the positioning block to further improve the stability of the fixation. The first shell and the second shell are sealed with respect to the pipeline through the sealing mechanism to avoid water leakage, so as to solve the problem that the bonding is often not firm when the water flow rate is fast, so that part of the water seeps out, and the water gradually destroys the viscosity between the waterproof tape and the pipeline, so that it is separated from the pipeline surface, resulting in insufficient reduction of the sealing effect of the waterproof tape.
[0014] 2. A stepped groove is provided inside the positioning groove of the utility model. The depth of the stepped groove is the same as the upper and lower heights of the inclined surface of the locking block, so that the locking block can be retracted into the stepped groove to facilitate the lateral movement of the positioning block inside the positioning groove. At the same time, the limiting ring is slidably connected to the inside of the first shell and the second shell, and the gap between the internal airbag and the first shell and the second shell is adjusted to be staggered, thereby improving the sealing effect of blocking the pipeline gap.

[0023] See also Figure 1-5 The utility model of the water pipeline leakage plugging device comprises a first shell 1, a positioning groove 4 is opened inside the first shell 1, an L-shaped positioning block 6 is arranged inside the positioning groove 4, a side of the positioning block 6 is fixedly connected to the second shell 2, the positioning block 6 is located on one side of the positioning groove 4 and a locking mechanism 5 is arranged, and the inner wall of the first shell 1 and the inner wall of the second shell 2 are both provided with a sealing mechanism 3.
[0024] See also Figure 3 The locking mechanism 5 includes a magnetic plate 501, one side of which is fixedly connected to the inside of the positioning groove 4, and a locking block 502 is provided on one side of the magnetic plate 501. The side surfaces corresponding to the magnetic plate 501 and the locking block 502 repel each other, so that the fixed magnetic plate 501 pushes the locking block 502 to move, so that the locking block 502 is separated from the positioning block 6, and the positioning block 6 can move freely laterally inside the positioning groove 4.
[0025] See also Figure 3 The outer surface of the locking block 502 is slidably connected to the inner wall of the positioning groove 4, and a slope is provided on one side of the locking block 502. The side of the locking block 502 facing the inner wall of the first shell 1 is an arc-shaped surface, and has the same curvature as the inner arc surface of the first shell 1, so as to protect the locking block 502 from being lifted up from below, and at the same time, the upper slope facilitates the downward movement of the locking block 502.
[0026] See also Figure 3The locking mechanism 5 also includes a stepped groove 503, the depth of which is the same as the upper and lower heights of the inclined surface of the locking block 502. The stepped groove 503 is convenient for limiting the detachment of the locking block 502, and at the same time, it is convenient for storing the locking block 502 to release the locking effect of the positioning block 6.
[0027] See also Figure 5 The sealing mechanism 3 includes a limiting ring 301, and the cross-sectional shape of the limiting ring 301 is T-shaped, wherein the outer surface of one group of limiting rings 301 is slidably connected to the inner wall of the first shell 1, and the outer surface of the other group of limiting rings 301 is slidably connected to the inner wall of the second shell 2. When the first shell 1 and the second shell 2 are locked in the final position when the positioning block 6 moves to the final position, the two limiting rings 301 are just butted together, so that the limiting ring 301 on the first shell 1 can be rotated a certain angle and inserted into the second shell 2, so that after the two limiting rings 301 are semi-circularly engaged and rotated, they are staggered with the first shell 1 and the second shell 2 to improve the stability of the locking.
[0028] See also Figure 5 The inner walls of the two sets of limiting rings 301 are fixedly connected with an air intake pipe 302, and one end of the air intake pipe 302 is fixedly connected with an air bag 303. The air intake pipe 302 can use a valve core to facilitate internal inflation. When necessary, the gas inside the valve core is supported to release the gas, so that the air bag 303 shrinks or expands to block the water pipe.
[0029] See also Figure 3 A sealing strip 7 is fixedly connected to one side of the first shell 1, and the outer surface of the sealing strip 7 is slidably connected to the inner wall of the second shell 2. The sealing strip 7 is arranged between the first shell 1 and the second shell 2 to improve the sealing effect.
[0030] When using the utility model: positioning grooves 4 are opened on the upper and lower sides of one side of the first shell 1, and a positioning block 6 is provided on the second shell 2 corresponding to the first shell 1. The positioning block 6 is L-shaped and is provided on one side of the pipeline through the first shell 1. Then, the second shell 2 is inserted into the positioning groove 4 through the positioning block 6, and the first shell 1 and the second shell 2 are covered on the surface of the pipeline. At the same time, the positioning block 6 moves into the positioning groove 4, and the locking block 502 is pushed along the inclined surface on the locking block 502 to move so that the locking block 502 is directed toward the inside of the first shell 1. Then, after the positioning block 6 is completely moved into the positioning groove 4, it moves transversely along the axis of the covering of the first shell 1 and the second shell 2, so that the L-shaped positioning block 6 moves transversely in the positioning groove 4 and is plugged in. When the positioning block 6 moves transversely to the specified position After being placed, the first shell 1 and the second shell 2 are locked, and then the limiting ring 301 is rotated to make the limiting ring 301 drive the airbag 303 to rotate ninety degrees, so that the limiting ring 301 on the first shell 1 spans the first shell 1 and the second shell 2, further locking the first shell 1 and the second shell 2, and at the same time, the gaps of the two docking airbags 303 are staggered with the gaps between the first shell 1 and the second shell 2, and then the airbag 303 is filled with gas through the air inlet pipe 302 to expand the airbag 303, filling the first shell 1 and the second shell 2, and squeezing on the surface of the pipeline to block the gap on the pipeline, and at the same time, the expansion of the airbag 303 drives the locking block 502 to move upward, against the positioning block 6 on one side, and locks the positioning block 6, thereby improving the stability of the locking between the first shell 1 and the second shell 2.
