Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pipeline repairing device, and particularly relates to a water conservancy pipeline repairing device and a repairing method. BACKGROUND

[0002] In water conservancy projects, surface water or underground water is distributed through water conservancy pipelines to flow to the places where it is needed, so as to meet the demand for water resources. When the water conservancy pipeline is damaged, the pressure water in the water conservancy pipeline will be sprayed out from the damaged position. At this time, the damaged position of the water conservancy pipeline needs to be repaired.

[0003] In the prior art, two arc-shaped plates are sleeved on the water conservancy pipeline for repairing. Specifically, the two arc-shaped plates are first sleeved on the water pipeline, and the positions of the two arc-shaped plates are preliminarily fixed by bolts. At this time, the arc-shaped plates can slide along the water conservancy pipeline. When the arc-shaped plates slide to the damaged position of the water conservancy pipeline, the arc-shaped plates are continuously slid and covered on the damaged position of the water conservancy pipeline. Since a valve is arranged on one of the arc-shaped plates, the valve is in an open state during the sliding of the arc-shaped plates. When the arc-shaped plates cover the damaged position of the water conservancy pipeline, the water sprayed out from the damaged position of the water conservancy pipeline will be sprayed out from the valve position of the arc-shaped plate. At this time, the operator tightens the bolts on the two arc-shaped plates by using a tool, so as to fix the two arc-shaped plates on the water conservancy pipeline. Then, the valve is closed, and the repairing of the damaged position of the water conservancy pipeline is completed.

[0004] In the above repairing method, after the arc-shaped plates cover the damaged position of the water conservancy pipeline, in order to facilitate the tightening of the bolts and reduce the spraying of the pressure water from other positions of the arc-shaped plates, the pressure water is continuously sprayed out from the valve position, which easily causes the waste of water resources.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and advantages of the application clearer, the application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0036] Please refer to Figs. 1-3 , a water conservancy pipeline repairing device provided by the application will be described. The water conservancy pipeline repairing device comprises a first arc-shaped plate 1, a second arc-shaped plate 2 and a valve 3; the first arc-shaped plate 1 and the second arc-shaped plate 2 respectively have a hinged end 11 and a connecting end 12; the hinged end 11 of the first arc-shaped plate 1 and the hinged end 11 of the second arc-shaped plate 2 are hinged to each other, and the connecting end 12 of the first arc-shaped plate 1 and the connecting end 12 of the second arc-shaped plate 2 are connected by bolts; the valve 3 is connected to the outer side wall of the first arc-shaped plate 1; the first arc-shaped plate 1 has a water passing hole 13 which is in communication with the valve 3; wherein the inner side wall of the first arc-shaped plate 1 is provided with a water bag 4 at a position corresponding to the valve 3, and the water bag 4 has an avoiding space 41 for avoiding the water passing hole 13; the water bag 4 has a water passing pipe 42 which is detachably connected with the valve 3; in the initial state, the inside of the water bag 4 is in a negative pressure state, and the valve 3 is in a closed state.

[0037] The water conservancy pipeline repairing device provided by the application can reduce the water spouted in the process of tightening the bolt, compared with the repairing method in the prior art, and can save water resources.

[0038] For example, the inner circumferential wall of the first arc-shaped plate 1 and the second arc-shaped plate 2 is provided with a sealing pad, when the first arc-shaped plate 1 and the second arc-shaped plate 2 clamp the water conservancy pipeline, the sealing pad on the first arc-shaped plate 1 abuts against the first arc-shaped plate 1 and the water conservancy pipeline, and the sealing pad on the second arc-shaped plate 2 abuts against the second arc-shaped plate 2 and the water conservancy pipeline, thereby playing a sealing role. The sealing pad on the first arc-shaped plate 1 avoids the position of the water bag 4, that is, the sealing pad on the first arc-shaped plate 1 has a through hole for avoiding the water bag 4.

[0039] In some embodiments, as shown in Figs. 1-3 The water pipe 42 is a hose, and the water pipe 42 is connected with the quick connector; the water pipe 42 is connected with an on-off valve (not shown in the figure), and the on-off valve is closed before the water pipe 42 is separated from the quick connector, so that the water bag 4 is in a pressure maintaining state.

[0040] It should be noted that before use, the valve 3 on the first arc-shaped plate 1 is in a closed state, at this time, the on-off valve can be opened; when the water conservancy pipeline damage position is located in the water bag 4 avoiding space 41, the valve 3 is opened, so that water can enter the water bag 4, and then the water bag 4 seals the gap between the first arc-shaped plate 1 and the water conservancy pipeline. After the first arc-shaped plate 1 and the second arc-shaped plate 2 are fixed on the water conservancy pipeline, the valve 3 is closed, and the on-off valve is closed, at this time, the water pipe 42 can be detached from the quick connector; after the water pipe 42 is separated from the quick connector, the water bag 4 is in a pressure maintaining state, and can still play a sealing role.

[0041] When water needs to be taken from the valve 3 position, the water pipe 42 can be separated from the valve 3, without affecting water taking.

[0042] In some embodiments, as shown in Figs. 1-3 The inner side wall of the first arc-shaped plate 1 is provided with a placing groove 14 for placing the water bag 4.

[0043] It should be noted that by arranging the placing groove 14 on the inner side of the first arc-shaped plate 1, the water bag 4 can be placed in the placing groove 14 to provide installation space for the water bag 4. After the water bag 4 is filled with water, one side of the water bag 4 abuts against the bottom wall of the placing groove 14, and the other side of the water bag 4 abuts against the water pipeline. Through the above arrangement, the connection between the water bag 4 and the inner side wall of the first arc-shaped plate 1 can be improved, and the sealing effect can be improved.

[0044] In some embodiments, as shown in Figs. 1-3 The outer side wall of the water bag 4 is provided with an elastic sealing pad. After the water bag 4 is filled with water, the water bag 4 pushes the elastic sealing pad to fill the gap between the first arc-shaped plate 1 and the outer peripheral wall of the water pipeline.

[0045] It should be noted that by arranging the elastic sealing pad on the outer side wall of the water bag 4, the elastic sealing pad can change with the deformation of the water bag 4. After the water bag 4 is filled with water, the elastic sealing pad can abut against the first arc-shaped plate 1 and the outer side wall of the water pipeline to achieve a sealing effect. After the first arc-shaped plate 1 and the second arc-shaped plate 2 are fixed in position by bolts, the water bag 4 discharges part of the water. At this time, the water bag 4 is still in a pressure maintaining state, and the elastic sealing pad is still abutting against the first arc-shaped plate 1 and the outer side wall of the water pipeline to achieve a sealing effect. Therefore, through the above arrangement, the sprayed water can be reduced during the process of repairing the damaged position of the water pipeline, and water resources can be saved.

[0046] In some embodiments, as shown in Figs. 1-3 The water passing hole 13 has an internal thread, and the water passing hole 13 is used in threaded cooperation with the air extraction pipeline of the air extraction device. The air extraction device is a prior art, and will not be described here.

[0047] It should be noted that before use of the water bag 4, when the water bag 4 is not in a negative pressure state, the air in the water bag 4 can be extracted through the connection of the air extraction pipeline and the water passing hole 13 and the start of the air extraction device. Then the valve 3 is closed to make the water bag 4 in a negative pressure state. When the first arc-shaped plate 1 and the second arc-shaped plate 2 are slid to the damaged position of the water pipeline, the valve 3 is opened to make water enter the water bag 4, and then the water bag 4 seals the outer side wall of the first arc-shaped plate 1 and the water pipeline. The sprayed water between the first arc-shaped plate 1 and the water pipeline is reduced, and water resources can be saved.

[0048] In some embodiments, as shown in Figs. 1-3As shown, the hinged end 11 of the second arc-shaped plate 2 has a slot 111, and the hinged end 11 of the first arc-shaped plate 1 has a protrusion 112 for being inserted into the slot 111, and the position of the protrusion 112 close to the bottom wall of the slot 111 is an arc surface 113; the second arc-shaped plate 2 has a first insertion hole on both sides of the slot 111, and the protrusion 112 has a second insertion hole aligned with the first insertion hole, and the first insertion hole and the second insertion hole are inserted and matched with a rotating shaft 15.

[0049] It should be noted that the position of the two side ends of the slot 111 of the second arc-shaped plate 2 is also an arc surface 113, which can reduce interference and facilitate the rotation of the first arc-shaped plate 1 and the second arc-shaped plate 2 around the rotating shaft 15; after the rotating shaft 15 is inserted into the first insertion hole and the second insertion hole, the rotating shaft 15 can be fixed on the first arc-shaped plate 1, or the rotating shaft 15 can be fixed on the second arc-shaped plate 2; no matter whether the rotating shaft 15 is fixed on the first arc-shaped plate 1 or the second arc-shaped plate 2, the first arc-shaped plate 1 and the second arc-shaped plate 2 can rotate relative to the rotating shaft 15; taking the case that the rotating shaft 15 is fixed on the first arc-shaped plate 1 as an example, the outer side wall of the protrusion 112 has a threaded hole communicated with the second insertion hole, and after the rotating shaft 15 is inserted into the second insertion hole, the rotating shaft 15 can be tightly pressed against the protrusion 112 by tightening the bolt in the threaded hole, so that the rotating shaft 15 is relatively fixed with the protrusion 112. When the rotating shaft 15 is fixed on the second arc-shaped plate 2, the rotating shaft 15 can also be tightly pressed by the bolt, which will not be described here.

[0050] In some embodiments, as shown in Figs. 1-3 The connecting end 12 of the first arc-shaped plate 1 and the connecting end 12 of the second arc-shaped plate 2 respectively have a plurality of through holes along the length direction, and the through holes on the connecting end 12 of the first arc-shaped plate 1 correspond to the through holes on the connecting end 12 of the second arc-shaped plate 2 one by one; wherein, when the first arc-shaped plate 1 and the second arc-shaped plate 2 are sleeved on the water pipeline, the through holes on the first arc-shaped plate 1 are aligned with the through holes on the second arc-shaped plate 2, and the bolt can pass through the connecting end 12 of the first arc-shaped plate 1 and the connecting end 12 of the second arc-shaped plate 2 and be fixed by the nut.

[0051] It should be noted that when the first arc-shaped plate 1 and the second arc-shaped plate 2 are preliminarily fixed, the bolt and the nut are not tightly matched, and at this time the first arc-shaped plate 1 and the second arc-shaped plate 2 can move along the radial direction, and during the sliding process of the first arc-shaped plate 1 and the second arc-shaped plate 2 along the axial direction of the water pipeline, the second arc-shaped plate 2 can slide along the side wall of the water pipeline, which can increase the distance between the water bag 4 and the outer side wall of the water pipeline and reduce the friction between the water bag 4 and the outer side wall of the water pipeline. After the first arc-shaped plate 1 and the second arc-shaped plate 2 are slid into place, the first arc-shaped plate 1 and the second arc-shaped plate 2 can be clamped to the water pipeline by tightening the bolt, and the repairing process is completed; after the repairing is completed, the valve 3 on the first arc-shaped plate 1 is closed.

[0052] Based on the same inventive concept, the application further provides a repairing method, comprising the following steps:

[0053] The first arc-shaped plate 1 and the second arc-shaped plate 2 are sleeved on the water pipeline and are preliminarily fixed through bolts;

[0054] The first arc-shaped plate 1 and the second arc-shaped plate 2 are slid along the axial direction until the damaged position of the water pipeline is located in the avoiding space 41 of the water bag 4;

[0055] The valve 3 is opened, the water sprayed from the damaged position of the water pipeline enters into the water bag 4 through the valve 3 and the water pipe 42, the water bag 4 is inflated and fills the gap between the first arc-shaped plate 1 and the outer side wall of the water pipeline; after the water pressure in the water bag 4 is stable, the water pressure in the water bag 4 is the same as the water pressure in the water pipeline;

[0056] The bolts on the first arc-shaped plate 1 and the second arc-shaped plate 2 are tightened, so that the first arc-shaped plate 1 and the second arc-shaped plate 2 clamp the water pipeline and the water in the water bag 4 is discharged;

[0057] The valve 3 is closed.

[0058] For example, when the first arc-shaped plate 1 and the second arc-shaped plate 2 are preliminarily fixed, the first arc-shaped plate 1 and the second arc-shaped plate 2 can slide along the radial direction of the water pipeline; when the first arc-shaped plate 1 and the second arc-shaped plate 2 are slid along the axial direction, the second arc-shaped plate 2 is first contacted with the outer peripheral wall of the water pipeline, so that the water bag 4 has a gap with the outer peripheral wall of the water pipeline.

[0059] Through the above arrangement, when the first arc-shaped plate 1 and the second arc-shaped plate 2 are slid, the distance between the water bag 4 and the outer side wall of the water pipeline can be increased, and thus the friction between the water bag 4 and the outer side wall of the water pipeline is reduced.

[0060] For example, when the water bag 4 is inflated before use, the air in the water bag 4 is extracted through the air extraction device, so that the water bag 4 is in a negative pressure state.

[0061] The air extraction pipeline of the air extraction device is connected to the water passing hole 13 of the first arc-shaped plate 1, and then the air extraction device is started to extract the air in the water bag 4.

[0062] For example, before the first arc-shaped plate 1 is sleeved on the water pipeline, sealing glue is applied on the outer side wall of the water bag 4; through the above arrangement, the sealing effect of the water bag 4 can be improved.

[0063] The above only describes the preferred embodiments of the application and is not used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
