Description

TECHNICAL FIELD

[0001] The utility model belongs to pipeline repair technical field, concretely relates to a pipeline leakage emergency treatment device. BACKGROUND

[0002] Pipeline system is widely used in conveying liquid in various buildings and industrial facilities, and is a key component to ensure normal operation of the facilities. Among them, the emergency pipeline system such as fire has higher requirements for emergency handling capacity of sudden leakage. In the long-term use process, the pipeline often breaks due to corrosion, aging, mechanical damage or installation defects, etc., resulting in liquid medium leakage. Liquid medium leakage not only causes resource waste and environmental pollution, but also may cause equipment damage, electrical short circuit, ground slippery and other safety hazards, seriously affecting production safety and system stable operation. At present, the emergency repair and treatment for pipeline leakage mostly adopts methods such as quick plugging tape, temporary bandaging or simple flow guide device. Although these methods can realize temporary emergency disposal to some extent, there are still obvious limitations: first, most emergency devices have simple structure and limited pressure bearing capacity, and it is difficult to cope with the common high-pressure and large-flow leakage conditions in pipeline system, and the device is easy to fall off or the interface is easy to leak under the impact of medium; second, the traditional emergency device lacks internal fluid buffer structure, and the leakage fluid directly impacts the inner wall and the interface of the device, which not only aggravates the vibration and displacement risk of the device, but also easily leads to further expansion of the leakage point; third, the existing emergency device cannot be flexibly adjusted during the repair process, and has limited applicability in the emergency treatment of high-pressure pipeline leakage.

[0003] Chinese patent CN207527206U discloses a pipeline leakage emergency treatment device, which comprises a plugging insert pipe and a locking member for fixing the plugging insert pipe on the leakage pipeline. The plugging insert pipe is T-shaped and hollow, and is filled with viscoelastic material. The plugging insert pipe is made of flexible material. When the leakage hole is plugged, the plugging insert pipe is inserted into the hole and locked on the pipeline by the locking member to achieve temporary plugging of the leakage. However, this patent is only suitable for small-diameter, low-pressure medium leakage conditions, and cannot cope with common high-pressure injection and irregular fracture surface conditions in pipeline, and has limited applicability in the emergency treatment of high-pressure pipeline leakage.

[0029] The number of the support legs 6 is three, and the three support legs 6 are uniformly distributed along the outer wall of the flow guide pipe 2.

[0030] Three support hinge seats 8 are fixedly arranged on the outer wall of the flow guide pipe 2, and the top ends of the three support legs 6 are respectively hinged to the three support hinge seats 8.

[0031] An adjusting sliding ring 9 is slidably sleeved on the outer wall of the flow guide pipe 2, three support connecting rods 10 are hinged to the adjusting sliding ring 9, and the ends, away from the adjusting sliding ring 9, of the three support connecting rods 10 are respectively hinged to the corresponding three support legs 6.

[0032] The water hose connector 7 comprises a fixed clamp 701 and a movable clamp 702, the fixed clamp 701 is fixedly connected with the bottom end of the flow guide pipe 2, and the movable clamp 702 is detachably clamped on the fixed clamp 701.

[0033] A sealing ring is arranged between the abutting end faces of the fixed clamp 701 and the movable clamp 702.

[0034] The end, away from the fixed clamp 701, of the movable clamp 702 is fixedly connected with a drainage water hose.

[0035] The inclination angle of the bottom end of the flow guide pipe 2 is 30-60°.

[0036] A on-off handle 11 is rotatably arranged on the flow guide pipe 2, and a flow guide valve 12 fixedly connected with the on-off handle 11 is arranged in the flow guide pipe 2.

[0037] The material of the interface body 1 is stainless steel, aluminum alloy or copper alloy.

[0038] Working process and principle:

[0039] I. Transportation preparation stage

[0040] The whole device is transported to the leakage site, the adjusting sliding ring 9 is slid upwardly on the outer wall of the flow guide pipe 2, the three support legs 6 are synchronously folded inwardly through the linkage of the three support connecting rods 10, so as to reduce the occupied space and facilitate transportation.

[0041] II. Installation stage

[0042] Move the device under the damaged pipeline, slide down the adjusting sliding ring 9, and expand the three supporting legs 6 synchronously through the supporting connecting rod 10 to make the device stand stably on the ground. Align the top end of the interface body 1 with the damaged part of the pipeline and adhere to it, and realize the tight sealing with the irregular damaged edge by using the guiding effect of the interface body 1 and the deformation ability of the flexible sealing element 3.

[0043] III. Flow guiding stage

[0044] Connect one end of the drainage hose with the movable clamp 702, and then clamp the movable clamp 702 on the fixed clamp 701 fixed at the bottom end of the flow guide pipe 2, and the sealing ring between the butt joint end faces of the two ensures the sealing of the connection without water leakage. Rotate the on-off handle 11 arranged on the flow guide pipe 2 to drive the internal flow guide valve 12 to rotate, which can preliminarily adjust or completely open the flow guide.

[0045] IV. Buffering stage

[0046] After the high-pressure leakage water flow enters the interface body 1, it first directly impacts the buffer flow guide cone 4 with the top cone. Under the impact of the water flow, the buffer flow guide cone 4 can rotate relatively, converting part of the fluid impact energy into rotational kinetic energy, thereby weakening the direct impact force on the device. Subsequently, the water flow spreads to all directions along the conical surface of the buffer flow guide cone 4, and falls into the slow flow steps 5 arranged circumferentially along the inner wall of the flow guide pipe 2 below. The water flow spreads on the slow flow steps 5, further consumes energy, reduces flow rate and turbulence, and makes the fluid enter the main body of the flow guide pipe 2 smoothly.

[0047] V. Drainage stage

[0048] The water flow after buffering and deceleration converges in the flow guide pipe 2. Since the bottom end of the flow guide pipe 2 is inclined to one side by 30-60°, the water flow naturally flows to the hose connector 7 under the action of gravity, and is safely guided to the designated discharge point through the drainage hose. In this process, the opening of the flow guide valve 12 can be adjusted in real time by operating the on-off handle 11 to control the drainage flow.

[0049] VI. Device folding

[0050] After the leakage treatment is completed, close the flow guide valve 12 and disconnect the movable clamp 702 from the fixed clamp 701. Fold the supporting legs 6, and then move the device away from the scene to complete the entire emergency treatment operation.
